Description

The invention relates to a device for mechanical monitoring and / or securing the operative position of opening closures, such as e.g. Windows, doors, gaps or the like, assembled, electrical or electronic proximity switches, especially those with magnetic contacts, in object surveillance and intrusion detection systems, in which the contact part on one element of the opening lock, e.g. on the fixed frame of the window or door, and the trigger part on the other element of the opening lock, for example on the wing of the window or door, is attached.

With object surveillance and intrusion alarm systems, security areas in buildings or the like are monitored by assigning all closable openings provided in the space limitations, such as windows, doors, gaps or the like, electrical or electronic proximity switches, primarily those with magnetic contacts are each connected to a reporting and / or alarm center.

With such object monitoring and intrusion detection systems, it is important that, in addition to the required opening monitoring, a locking monitoring and / or security of each individual opening lock is also ensured.

The fulfillment of this requirement is important because a window or door leaf, a hatch cover or the like - especially if it is a little stiff to move - can only be pressed shut and thus only closed without being locked, i.e. locked. In such a case, the associated electrical or electronic proximity switch comes into its active position and then signals the correct closed position of the opening closure in question. Due to uncontrollable external influences, such as gusts of wind, draft or the like, however, the wing or the flap can then be moved in the opening direction, so that an unwanted false or false alarm is triggered when the object monitoring and intrusion alarm system is switched on. To avoid such false or false alarms, it must therefore be ensured that each individual opening closure - window, door, hatch or the like - not only assumes its closed position, but is also effectively fixed therein, in particular locked or closed, when the object monitoring - and intrusion alarm system is armed.

It is therefore known to equip the individual opening closures with locking contacts and / or to assign so-called throwing springs to them, which counteract a simple pressing without simultaneous locking.

While the usual bolt contacts are not only assembly-intensive, but also sensitive to moisture and therefore susceptible to corrosion and error reporting, the use of the suspension springs proves to be disadvantageous in that they can weaken or break after a certain period of use and then in most cases cannot be replaced will.

The invention now aims to provide a device for mechanical monitoring and / or securing the operative position of electrical or electronic proximity switches mounted on opening closures, such as windows, doors, hatches or the like, primarily such magnetic contacts, in object monitoring and Intrusion alarm systems to specify the Entry of window or door sashes and hatch covers or hatches into their closed position is blocked as long as a special lock or a special lock is not actuated.

According to the invention, such a device is characterized by an element on the opening closure, e.g. on the fixed frame, attachable support or abutment bracket and an adjusting stop which can be attached next to this on the other element of the opening lock, for example on the sash, the support or abutment bracket at a distance in front of the closing level of the opening lock exceeding the response distance of the proximity switch one in the infeed path of the adjusting stop horizontal support stop, to which a slot-like or groove-like guide link adjoins the closing plane, and the control stop sits in a guide, as well as therein between an operative position assigned to the support stop and at least one blocking or assigned to the guide link The engagement position can be changed manually.

This mechanical monitoring and / or securing device designed according to the invention effectively prevents a window or door leaf, but also a hatch cover or a hatch flap, from being able to assume the closed position as long as no locking operation is carried out.

It is also advantageous that a device according to the invention can be retrofitted in the area of windows, doors and hatches or the like if these are to be included in object monitoring and intrusion detection systems by equipping them with proximity switches.

It has proven to be recommendable if, in an embodiment of the invention, an abutment stop is assigned to at least the blocking or engagement position of the actuating stop in the guide link which is furthest away from the active position, which abutment stop counteracts the support stop Has position and thereby prevents opening of the wing or the flap or the lid to a limited extent, as long as no unlocking is carried out.

It has been found to be particularly advantageous if the abutment stop is at a distance below the response distance of the proximity switch from the closing plane of the opening lock, because this ensures that the proximity switch remains in the active position even when the wing, the flap or the cover of the locked opening lock , for example for ventilation purposes, takes a gap opening position.

So that when the support stop is manually shifted from its operative position into the locked or engaged position of the wings, the flap or the cover of the opening closure inevitably comes into that position relative to the closing plane in which the associated proximity switch assumes its active position, it is provided that the Guide link in the area between the support stop and the abutment stop - for example deviates from the vertical - inclined course and approaches the closing plane of the opening closure in the direction of the abutment stop.

Another design measure of the device according to the invention consists in that the guide link is provided in a side surface of the support or abutment bracket with an approximately Z-shaped course, the one link leg facing away from the closing plane of the opening closure having an entry and exit opening for one end has the actuating stop, while its other end is delimited by the support stop, which is directly adjoined by the upright link section, which merges into the link leg facing the closing plane of the opening closure.

Another recommended measure is that the support stop sits on a slide in the housing-like guide, which is connected to an operating handle. The latter can be designed as a slide button or button. However, a rotary knob can also be provided as an operating handle, which is in drive engagement with the slide via a crank and / or toothed drive.

In many cases, however, it can also be advantageous if the operating handle can be fixed, in particular latched, to the housing-like guide at least in both sliding end positions of the slide.

The operating handle can also be fixed to the housing-like guide in a middle sliding position of the slide, e.g. engage, the actuating stop forming a night ventilation sash stop with an upright link section of the guide link in the support or abutment bracket.

Particularly when the device is installed in the vicinity of the usual operating handle of a window or door fitting, a tilt-and-turn window or a tilt and turn door can be fixed in position relative to the fixed frame both in a gap ventilation pivot position and in a gap opening tilt position.

A structurally advantageous embodiment of the device according to the invention results if the slide carrying the actuating stop and the housing-like guide containing it have an angular cross-section and on two boundary surfaces of one element of the opening closure, which are at right angles to one another, e.g. on the end face and the rollover circumferential surface of the casement of a window or door, can be attached.

Another development feature essential to the invention is that the support or abutment bracket and the housing-like guide for the associated actuating stop each contain at least one receiving chamber, in which on the one hand the contact part and on the other hand the trigger part of a proximity switch can be accommodated. This measure not only reduces the assembly effort because the proximity switch can be struck at the same time as the device for mechanical monitoring and / or securing its operative position at the opening lock, but it is also ensured that the response distance of the proximity switch corresponds exactly to the installation conditions of the mechanical monitoring device. and / or securing device is coordinated.

According to the invention, it is further possible that the effective range of the proximity switch can be covered by the slide carrying the actuating stop in a final sliding position, while this effective range can be released in its other final sliding position. In such an embodiment, if the mechanical monitoring and / or securing device is moved from its locking position into the unlocking position, then the electrical or electronic proximity switch triggers a signal before the actual opening movement of the opening closure in question has even started.

Another type of device according to the invention is characterized in that the actuating stop is held in the sliding end position assigned to the support stop by weight and / or spring force and that the guide link in its area closest to the closing plane of the opening closure has an end section directed parallel to it, in which the stop can be snapped in by the weight and / or spring force.

This design of the mechanical monitoring and / or securing device is recommended for cases in which it is important that a locking of the opening closure takes place automatically when approaching its closing plane after the actuating stop has previously been manually brought into engagement with the slot-like or groove-like guide link from the effective area of the associated support stop. When designing a mechanical monitoring and / or securing device, it proves to be expedient if the sliding end position of the actuating stop, which releases the effective range of the proximity switch. which corresponds to the basic position determined by the direction of action of the weight and / or spring force.

The object on which the invention is based can also be achieved by an element of the opening closure, e.g. on the fixed frame, attachable support or abutment bracket and an adjusting stop which can be attached next to this on the other element of the opening lock, for example on the sash, the support or abutment bracket at a distance in front of the closing level of the opening lock exceeding the response distance of the proximity switch one in the infeed path of the adjusting stop horizontal support stop, to which guide surfaces for the actuating stop and an abutment stop running approximately parallel to the support stop are connected, and the actuating stop is seated in a guide and can be manually changed between an operative position assigned to the support stop and the abutment stop and a disengagement position is.

In this case too, the abutment stop can have a position facing away from the support stop and can have a distance from the closing plane of the opening lock that is less than the response distance of the proximity switch. The guide surfaces should have an inclined course in the area between the support stop and the abutment stop and should approach the closing plane of the opening closure in the direction of the abutment stop. These guide surfaces can be provided in a side surface of the support and abutment bracket with an approximately V-shaped course.

In the sliding end position assigned to the support stop and the abutment stop, the actuating stop is held by spring force.

For the optional right-hand and left-hand installation of the device, it is advantageous according to the invention if the operating handle is detachably and relocatable in connection with the slide bearing the support stop. A compression spring can be held and supported on the operating handle, which engages in a recess in the housing and has its abutment in this.

Also to be recommended is a further development, which consists in the fact that the housing has an integrally formed angular tab that engages around the support or abutment bracket.

It has also proven to be useful if the support stop, abutment stop and guide surfaces are provided on a shaped piece which is adjustably held and guided on the support and abutment bracket. The shaped piece can be in a continuously adjustable engagement with the support and abutment bracket via a threaded pin.

Yet another design of the device with which the set goal is achieved is characterized according to the invention by at least two snap catches arranged in a housing on one element of the opening lock, for example the fixed frame, and movable in parallel to the closing plane, one of which traverses a transverse to the Closing plane, but only in the direction away from this supporting stop and the other also transversely to the closing plane, but only acting towards this supporting stop, forms that the supporting stops are at a distance from the closing plane of the wing and are at a distance from one another that are equal to the width an engaging element seated on the other element, for example the wing, is coordinated in such a way that the snap catch having the support stop acting in the direction away from the closing plane on the one hand can be disengaged against the spring force by the engagement member via a run-up slope and on the other hand by a handle, while the catch latch having the support stop acting in the direction towards the closing plane can only be disengaged together with the first catch latch against spring force, and that the support stops on the housing in a response distance of the proximity switch adapted maximum distance in front of the closing plane of the opening lock.

The advantage of this device for mechanical monitoring and / or securing the active position on opening closures such as Windows, doors or the like. Assembled, electrical or electronic proximity switches is that an automatic fixation of the wing or the flap of the opening lock in a position ensuring the response of the proximity switch is also effected when the wing or the flap is still is not properly locked or locked on the fixed frame.

For optimum position fixation, it is advantageous if, according to the invention, the distance between the support stops of the two snap catches is matched at least approximately free of play to the cross-sectional width of the engagement member.

According to a further feature of the invention, it is proposed that both snap catches in the housing in adjacent levels, e.g. as a slide, are movable so that they carry transversely engaging driver stops lying transversely to their direction of movement and that the driver stop of the first catch latch lies in the direction of action of the spring force before the driver stop of the second catch latch.

In the context of the innovation, it has proven particularly useful if each catch latch is acted upon by its own spring force.

Furthermore, it is provided that only the first catch trap is provided with or can be connected to an actuating handle, which can also be brought into effect on the second catch trap via the driver stops.

According to the invention, however, it is also possible that either the two snap catches can be disengaged together by a handle engaging the first snap catch or the second snap catch can be disengaged for all of them by a handle connected to it and both handles can be removed from the housing at different points stick out.

An embodiment of this device according to the invention in which the second snap latch has at least one further support stop, which is effective in the direction away from the closing plane and is assigned to the closed position of the sash on the fixed frame, has proven particularly useful.

It has also proven useful, however, if the second catch trap in the area between its two support stops is additionally provided with at least one locking recess for the engaging member, which can be overcome in both possible directions of movement of the wing, but at the same time ensures that one of the two support stops with the The engagement member is able to enter into active connection.

An inlet slot for the engagement member, which extends essentially transversely to the direction of movement of the snap catches, can also be assigned to the snap catches in the housing.

However, it is also advantageous if the housing and the first catch latch are each designed symmetrically to a transverse plane, while the second catch latch is designed symmetrically to a longitudinal plane. Using the same components, the innovation can Device can be assembled for either right-handed or left-handed.

From a structural point of view, it has finally proven itself if the second snap catch is received in flat recesses in the first snap catch.

In Fig. 1 of the drawing, a window is shown in a purely schematic representation, which on the one hand has a fixed frame 1 and on the other hand a wing 2. However, this can of course also be a door or any other opening lock, for example a hatch that can be closed by a lid or a flap.

The window shown in Fig. 1 is, for example, a tilt-and-turn window, in which the sash 2 relative to the fixed frame 1 can either be brought about a lateral, vertical axis 3-3 from the closed position into a rotational opening position, or but with which it can be brought from the closed position into the tilt opening position about a lower, horizontal axis 4 - 4. The tilt opening position is limited by an opening device 5, which is installed, for example, between the upper horizontal leg of sash 2 and fixed frame 1 and at the same time also has such a design that it forms the upper swivel joint when the sash 2 is opened. At the intersection of the two hinge axes 3 - 3 and 4 - 4, the wing 2 is supported on the fixed frame 1 by a so-called corner bearing 6.

The window is also assigned an espagnolette fitting 7, by means of which not only the sash 2 can be fixed to the fixed frame 1 in the closed position via locking plates 8 and locking plates 9, but which also serves to actuate a tilt lock 10, which consists of a wing-side tilt bolt 11 and a frame-side tilt lock plate 12. Finally, a locking device 13 is actuated via the connecting rod fitting 7, which consists of a locking member 14 on the leaf side and a locking engagement 15 provided on the opening device 5, in such a way that the opening device 5 for the closed position and the rotating opening of the leaf 2 can be coupled to the latter while it is unlocked for the opening of the wing 2 tilt.

So that the window according to FIG. 1, but also an opening closure designed, for example, as a door or as a hatch, can be included in an electrical or electronic object monitoring and intrusion detection system, a proximity switch 16 is provided between the sash 2 and the fixed frame 1 , whose contact part 17 can be designed as a magnetic contact, to which a suitable permanent magnet is then assigned as a trigger part 18.

While the contact part 17 is advantageously mounted on the fixed frame 1, the associated trigger part 18 of the proximity switch 16 is located on the wing 2.

The structure and mode of operation of the proximity switch 16 are known per se. The contact part 17 designed as a magnetic contact can contain at least one reed contact, which can be designed as a make contact, a break contact or also as a changeover contact. The trigger part 18 of the proximity switch contains a permanent magnet, which can be designed with different magnetic field strengths.

Contact part 17 and trigger part 18 of the proximity switch 16 are arranged between the wing 2 and the fixed frame l so that the proximity switch assumes its active position when the wing 2 is in the closed position on the fixed frame 1 and also remains therein as long as the wing 2 is only around the fixed frame 1 a small gap distance is moved in the opening direction. The opening gap can be at a certain point in a range between 30 and 40 mm, it being located on a tilt-and-turn window, preferably on the closure side between the sash 2 and the fixed frame 1, and therefore both opening options - turning and tilting - of Wing 2 monitored relative to the fixed frame 1.

As long as the wing 2 is in the closed position on the fixed frame 1 or the limited size of the opening gap is not exceeded, the proximity switch 16 is in the switching state which signals the proper closing state of the opening lock to the object monitoring and intrusion detection system. If, however, the magnitude of the opening gap between the sash 2 and the fixed frame 1, which is predetermined, for example by the magnetic field strength in the triggering part 18, is exceeded, the proximity switch 16 responds and signals the object monitoring and intrusion detection system to the opening state of the opening closure in question, which at arming the system would trigger an alarm.

A possible structure for an object monitoring and intrusion detection system can be seen in FIG. 2. According to FIG. 2, the system is designed, for example, to monitor at least three different opening closures A, B and K, with such an interconnection of the magnetic contacts 17a, 17b and 17k that the opening closures A, B and K cannot be individually identified from the central station Z. further is possible.

The design of the object monitoring and intrusion alarm system according to FIG. 2 is of such a type that it can work with up to 10 proximity switches 17a to 17k, thus ensuring the individual identification of ten different opening closures A - K.

In addition to the proximity switch 17a, 17b ... 17k, which is designed as a changeover contact, there is a signaling resistor 19a, 19b ... 19k and a so-called pointed connection 20a, 20b ... 20k for each opening closure to be monitored. H. each proximity switch 17a, 17b ... 17k works with a so-called 5-wire circuit. So that the individual identification of the opening closures A, B ... K can be reached via the resistance measurement in the control center Z, a terminal resistor 21 must be connected in series after the last proximity switch 17k, each of the signaling resistors 19a, 19b ... 19k and also the terminating resistor 21 has one and the same resistance, for example of 680 ohms.

Since the object monitoring and intrusion detection systems have a design that responds to the closed state of the monitored opening locks, regardless of whether they are also locked or locked, it is important to prevent the wing 2 from being designed as windows or doors or the lid or the flap of opening closures configured as hatches can not only be closed, but that they must then also be closed or locked. In order to ensure this, each opening lock A, B ... K connected to the object monitoring and intrusion detection system is a special mechanical monitoring and / or

Associated safety device 22, which is shown only schematically simplified in Figure 1 of the drawing. The structure and mode of operation of this mechanical monitoring and / or securing device 22 is, however, shown in FIGS. 3 to 10 of the drawing in different exemplary embodiments.

Each mechanical monitoring and / or securing device 22 comprises a support or abutment bracket 23 and an associated actuating stop 24. According to FIG. 1, the support or abutment bracket 23 is mounted on the inside of the fixed frame 1, while the actuating stop is on the side next to it Wing 2 is attached.

For a better understanding of the design and mode of operation of the mechanical monitoring and / or securing device 22 to be explained below, it is important to briefly explain the mode of operation of the proximity switches designed as magnetic contacts.

A reed contact is in a certain starting position, for example open. If you bring a magnet serving as a trigger part in the right direction close enough to the reed contact, this changes its position. It therefore comes, for example, into the rest position corresponding to the other switching position. If the magnet is removed again, the reed contact falls back into its original position. The maximum distance between the contact part 17 and the trigger part 18, at which the reed contact is brought from its rest position into its working position, is the so-called response level. It is assumed here that this response distance for the monitoring of opening closures is approximately 35 mm. As long as, for example, the wing 2 of a window or a door in the area of the closure side is still more than 35 mm from the closing plane of the fixed frame 1, the proximity switch 16 remains in its rest position. However, if the wing 2 approaches this closing level of the fixed frame 1, then the proximity switch 16 responds, ie it comes from the predetermined rest position into the active position.

The mechanical monitoring and / or securing device 22 is now designed and mounted on the window, on the door, on the hatch or on another opening lock in such a way that its manual actuation is indispensable for each closing operation if the response distance of the respective opening lock is assigned Proximity switch 16 is to be reached. A first exemplary embodiment of the mechanical monitoring and / or securing device 22, which takes account of the prerequisites mentioned, is shown in FIGS. 3-7 of the drawing.

Here, the support or abutment bracket 23 is rigidly attached to the room-side end face of the fixed frame 1 of a window, a door or the like, in the area of the closure side of the wing 2 with a parallel distance from the upright rollover peripheral surface 25 of the same.

The support or abutment bracket 23 is equipped on one broad side with a slot or groove-shaped guide link 26 which has a multiple angled course (FIGS. 6 and 7) and on one side, namely on the one from the closing plane of the opening lock 1, 2 turned away, end is provided with an inlet and outlet opening 27 to which a horizontal link leg or branch 26a connects. This link leg or branch 26a merges into a downward link link section 26b, which in turn is followed by a horizontal link section or branch 26 c, which faces the closing plane of the opening closure in question - windows 1, 2. One boundary surface of the downward link section 26b forms a support stop 28 over the entire length of the link section 26b, while the opposite boundary surface of this link section 26b acts as an abutment stop 29 over its entire length.

The support stop 28 in the link section 26 b of the guide link 26 has such a distance 30 from the closing plane 31 of the opening lock - window 1, 2 - that it exceeds the response distance of the proximity switch associated with this opening lock.

The support stop 28, but also a wall 32 carrying the abutment stop 29 on its inside, lie in the inlet path of the adjusting stop 24 mounted on the wing 2 or the like of the opening closure - window 1, 2. The adjusting stop 24 is, for example, a pin with a round cross-section The diameter of which is designed to be somewhat smaller than the width of the inlet and outlet opening 27 and also as the distance between the support stop 28 and the abutment stop 29 in the guide link 26 on the support or abutment bracket 23. The actuating stop 24 is seated on a slide 33 , which is accommodated in a longitudinal guide 34 of a housing 35, the housing 35 being mounted on the wing 2 of the opening closure — windows 1, 2 — laterally next to the support or abutment bracket 23 mounted on the frame side.

The housing 35 with the guide 34 and also the slider 33 accommodated therein have an angular cross-sectional shape, so that they each lie with one leg on the end face of the wing 2 on the room side, while its other leg lies laterally next to the rollover circumferential surface 25 thereof. The stop 24 designed as a pin protrudes from one leg of the slide 33 through a longitudinal slot 36 of the housing 35, while an operating handle 37 is connected to the other leg of the slide 33 and passes through a longitudinal slot 38 in the housing 35.

The operating handle 37 is designed, for example, as a handle bolt. But it can also be shaped as a button or formed by a rotary handle, which then meshes with a toothing or an engagement slot in the slide 33 via a pinion or a crank pin. It is only important that by means of the operating handle 37 the actuating stop 24 carried by the slider 33 can be displaced between two specific end positions, in such a way that it is in one sliding end position at the level of the inlet and outlet opening 27, but in the other end sliding position is located at the level of the link leg or branch 26c.

In one sliding end position, the actuating stop 24 according to FIG. 6 can run through the inlet and outlet opening 27 of the support or abutment bracket 23 up to the support stop 28. However, a further closing movement of the leaf 2 of the opening closure - window 1, 2 - carrying the stop 24 is prevented. Only when the actuating stop 24 has been shifted into its other end switch position (FIG. 7) can the leaf 2 be moved further in the closing direction up to the closing plane 31-31, because the actuating stop 24 is free within the link leg or branch 26c is. However, the abutment stop 32 in this end sliding position of the actuating stop 24 in turn prevents the wing 2 from completely opening. The wall 32 carrying the abutment stop 29 also ensures, however, that the actuating stop 24 is only in its end position corresponding to FIGS. Sliding position can be brought into and out of operative connection with the support or abutment bracket 23 or its guide link 26.

Only after overcoming the frame-side support stop 28 by the wing-side actuating stop 24, that is to say after deliberately manually actuating the latter, can the wing 2 of the opening closure - window 1, 2 - be moved against the fixed frame 1 in the direction of its closed position in such a way that the existing proximity switch 16 responds and thus signals the desirable and at least limited locked state of the opening lock to the center Z (Figure 2).

The complete locking of the wing 2 on the fixed frame 1 in the closed position must still be effected by actuating the connecting rod fitting 7 via the locking pin 8 and the locking plates 9 (Figure 1).

However, if the connecting rod fitting 7 is not brought into its locking switch position, the wing 2 can be moved relative to the fixed frame 1, for example by wind pressure or tension, into the position by the actuating stop 24 and the restart 29 Move back the limited and limited locked opening position, in which the proximity switch 16 (FIG. 1) drops out, thus signaling the central station Z (FIG. 2) the opening state of the opening lock in question, although there is still a limited effective locking which still has to be overcome.

FIG. 8 of the drawing shows an embodiment for the support or abutment bracket 23 which counteracts this inadequacy. This is achieved in that the support stop 28 extends in the guide link 26 only over that area which is opposite the entry and exit opening 27 of the link leg or branch 26a. On the other hand, the abutment abutment 29 on the wall 32 only extends over the cross-sectional width of the lower link leg or branch 26c. Support stop 28 and abutment stop 29 lie almost on the same level within the guide link 26, i. H. the abutment stop 29 in the support or abutment bracket 23 according to FIG. 8 has moved a considerable amount closer to the closing plane 31 - 31 of the opening closure than in the exemplary embodiment according to FIGS. 6 and 7. In order to obtain this arrangement, the link section 26b has - deviating of the embodiment according to FIGS. 6 and 7 - a course inclined towards the vertical, whereby it approaches the closing plane 31 - 31 of the opening closure from top to bottom.

If, in the support or abutment bracket 23 according to FIG. 8, the actuating stop 24 is displaced by means of the operating handle 37 after it has run against the support stop 28d through the inlet and outlet opening 27, then the wing 2 approaches due to the inclined position of the link branch 26b the fixed frame 1 inevitably until the response distance of the proximity switch 16 (FIG. 1) is at least reached when the abutment stop 29 is reached. This ensures that after the proximity switch 16 has responded, the conditionally locked closing state of the leaf 2 relative to the fixed frame 1 can no longer be left as long as the actuating stop 24 is at the level of the abutment stop 29.

In some cases, it may be desirable to combine the proximity switch 16 with the mechanical monitoring and / or securing device in a unitary manner for the purpose of simplifying assembly and for optimizing the mode of operation. To achieve this goal, the support or abutment bracket 23 can, as indicated in FIGS. 6-8, be provided with molded-in chambers 39, in which, for example, the contact part 17 can then be accommodated. The associated magnet as the trigger part 18 can then be accommodated on or in the wing-side housing 35, in which the actuating stop 24 is displaceably guided. If the housing 35 and the slide 33 carrying the actuating stop 24 are made of non-magnetizable material, an arrangement of the magnet that plunges the release part 18 may be possible, in which the effect of this on the contact part 17 is shielded when the actuating stop 24 is in a sliding end position will, d. H. that it can influence the contact part 17 only in the other end sliding position of the actuating stop 24. This further optimizes the functional reliability of the overall system.

The types of mechanical monitoring and / or securing device described so far with reference to FIGS. 3 to 8 allow the setting of stomata between the wing 2 and the fixed frame 1 of an opening closure - windows 1, 2. However, they neither make it possible to lock the opening closure in its properly closed position, nor do they allow the immovable fixing of a certain gap opening width between sash 2 and fixed frame 1.

FIG. 9 of the drawing shows a support or abutment bracket 23 which is further developed by the support or abutment bracket 23 according to FIG. 8 and which by means of the actuating stop 24 can automatically lock the opening closure of its closed position after the response distance for the proximity switch 16 (FIG. 1) was undercut.

In order to effect the automatic locking, according to FIG. 9 the guide link 26 in the support or abutment bracket 24 is additionally equipped with a link leg or branch 26d running upwards from the rear end of the link leg or branch 26c.

Furthermore, a spring 40 is assigned to the slide 34 carrying the actuating stop 24 within the housing 35, which spring is indicated in FIGS. 3-5 by dash-dotted lines. This spring 40 seeks to keep the actuating stop 24 in its upper sliding end position. I.e. To overcome the stop action of the support stop 28, the actuating stop 24 must be brought into its lower sliding end position by the operating handle 37 against the action of the spring 40. If the wing 2 of the opening closure - window 1, 2 - is then moved in the direction of its closing plane 31 - 31, the actuating stop 24 within the link leg or branch 26c reaches the area of the adjoining link leg or branch 26d and becomes therein then shifted upward by the action of the spring 40. As a result, the leaf 2, which occupies the closed position, is fixed in position automatically relative to the fixed frame 1, which can only be canceled by pressing the actuating stop 24 again manually by means of the operating handle ₃₇ .

A conditionally fixed gap opening position of the wing 2 relative to the fixed frame 1 can be set according to FIG. 9 if a flat detent depression 26e is placed in front of the link leg or branch 26d within the link leg or branch 26c, into which the actuating stop 24 is acted upon by the force the spring 40 can indent. By relatively slight force acting on the wing 2, however, the actuating stop 24 can be brought out of the detent depression 26e either in the opening direction or in the closing direction, so that it penetrates either into the link section 26b or into the link section 26d.

Another variant of the training for the support or abutment bracket 23 is shown in Figure 10 of the drawing. This differs from the support or abutment bracket 23 according to FIG. 9 essentially in that instead of the relatively flat locking recess 26e, a link leg or branch 26f is provided, which extends parallel to the link leg or branch 26b extends.

As in the case of FIG. 9, the wing 2 is also fixed to the fixed frame 1 in its closed position in the support or abutment bracket according to FIG. 10 by spring-loaded engagement of the adjusting stop 24 in the link leg or branch 26d. On the other hand, the wing 2 can be fixed relative to the fixed frame 1 by automatically engaging the actuating stop 24 in the link leg or branch 26f in a gap opening ventilation position, from which it can be moved only after the actuating stop 24 has been depressed again.

Finally, it should also be mentioned that in some cases it can be advantageous if the adjusting stop 24 can be fixed in position on the housing 35 at least in its two possible sliding end positions. For this purpose, for example, only the slide button 37 needs to be provided with a cap spring-loaded in the axial direction, the edge of which comes into locking engagement with keyhole-like extensions at the ends of the longitudinal slot 38. By pulling the cap up against the spring force, the latching can then be released before the displacement of the actuating stop 24 is effected by means of the operating handle 37.

In a departure from the exemplary embodiment according to FIG. 8, the guide link 26 can also be designed such that the link leg 26c is completely absent, that is to say the link section 26b leads from the link leg 26a with a corresponding inclined position up to the closing plane 31-31. There it can then possibly run into the abutment stop 29.

The construction and mode of operation of a further type of mechanical monitoring and / or securing device 122 are shown in FIGS. 11 to 14 and 15 of the drawing using different exemplary embodiments.

Each mechanical monitoring and / or securing device 122 comprises a support and abutment bracket 123 and an associated engagement member 124. The support and abutment bracket 123 according to FIG. 12 is mounted on the inside of the fixed frame 101, while the engagement member 124 laterally next to it is attached to the wing 102.

The mechanical monitoring and / or securing device 122 is also designed and mounted on the window, on the door, on the hatch or on another opening lock in such a way that it has to be actuated with each closing operation if the response distance of the respective opening lock is assigned Proximity switch 16 is to be reached.

11 to 14, the support and abutment bracket 123 is rigidly attached to the room-side end face of the fixed frame 101 of a window, a door or the like, in the area of the closure side of the wing 102 with a parallel distance from the upright rollover Circumferential surface 125 of the same, as can be seen in FIGS. 13 and 14.

The support or abutment bracket 123 has a housing 126 which, in its side wall 126a which faces the rollover peripheral surface 125 of the wing 102, also contains a longitudinal slot 127 which breaks through the end face 126a at 127a and which is essentially transverse to the closing plane 128-128 of the Window, the door or the like. Extends, for example, approximately approximately horizontally.

The engagement member 124 interacts with the longitudinal slot 127, for example, via a pin 129 which is fixedly connected to the wing 102 via an angle plate 130.

In the housing 126 of the support and abutment bracket 123, a snap arrangement 131 is accommodated, which is formed by two snap latches 132 and 133, each of which is movably arranged parallel to the closing plane 128-128 of the window, the door or a similar opening lock. The snap catch 132 is constantly acted upon by a spring force 134, while the snap catch 133 is constantly under the action of a similar spring force 135.

In the example, both catch latches 132 and 133 are designed as slides which are movably guided transversely to the longitudinal slot 127 in the housing 126, and are normally held by the spring forces 134 and 135 in the operative position shown in FIGS. 11 and 12, in which they are fitted with at least two support stops 136 and 137 protrude transversely into the longitudinal slot 127. The two support stops 136 and 137 are at a distance 138 from each other, which is closely adapted to the cross-sectional width of the pin 129, which is located on the engagement member 124. The support stop 136 is located on the snap latch 132 and is arranged near the end of the longitudinal slot 127 opening out of the end wall 126 of the housing 126 at 127a in such a way that it acts in the direction transverse to the closing plane 128-128 of the window, the door or a similar opening lock and has a position facing this closing level 128-128.

The second support stop 137, on the other hand, is located on the second catch latch 133, also acts in the direction transverse to the closing plane 128-128 of the opening lock, but has an arrangement that is averted from this closing plane 128-128.

In front of the support stop 136, that is to say in direct connection to the opening 127a of the longitudinal slot located in the transverse wall 126b of the housing 126 127, the catch latch 132 is provided with a run-on slope 139 with which the pin 129 of the engaging member 124 can come into contact with one another during the closing movement of the wing 102 relative to the fixed frame 101. About the pin 129 of the engaging member 124, the catch latch 132 can be temporarily lifted out of the region of the transverse slot 127 against the restoring action of the spring force 134, so that the pin 129 of the engaging member 124 can enter the longitudinal slot 127 of the housing 126.

As soon as the pin 129 of the engaging member 124 has reached in the longitudinal slot 127 behind the support stop 136, the snap catch 132 is reset by the spring force 134 and thereby returns to its locked position. In this locked position, the support stop 136 engages in front of the pin 129 of the engagement member 124 and holds the wing 102 relative to the fixed frame 101 at a distance 140 (FIG. 14) against reopening. The distance 140 corresponds to the so-called response distance of the electrical or electronic proximity switch 16, which is assigned to the window, the door or a similar opening lock according to FIG. 1. Only by actuating a special handle 141, which protrudes, for example, through a slot 142 in the end wall 126b of the housing 126, can the catch latch 132 be raised against the spring force 134 in order to open its support stop 136 for the purpose of opening the wing 102 with the pin 129 of the Disengaging engagement member 124.

The catch latch 133 of the catch arrangement 131, which carries the second support stop 137, engages with a catch stop 143 formed by an angled leg 133a, a catch stop 144 which is located on the upper transverse edge of the catch catch 132. The spring force 135 acts from above on the angled leg 133a of the snap catch 133 and tries to keep the driver stop 143 with the driver stop 144 in constant contact.

This ensures that each disengagement movement of the catch latch 132, be it via the run-up slope 139 or the handle 141, also causes an disengagement movement of the catch latch 133 with its support stop 137. In the engagement position of the catch latch 132, however, the catch latch 133 can be moved independently of the catch latch 132 between its engagement position and its disengagement position, because then its driver stop 143 can be displaced relative to the driver stop 144. In this way it is ensured that the catch latch 133 with its support stop 137 can also be in the disengaged position, although the catch latch 132 with its support stop 136 assumes the engagement position.

The support stop 137 of the catch latch 133 ensures that the wing 102 is fixed in the position shown in FIG. 14, that is, while maintaining the response distance 140 for the proximity switch 116, against a further closing movement relative to the fixed frame 101.

Since the two mutually facing support stops 136 and 137 are relatively movable with respect to the distance 138, they can be designed so that in their operative position they pinch the pin 129 of the engaging member 124 with virtually no play between them and thereby give the wing 102 a good hold.

11 and 12 of the drawing, in particular, it can be seen that the catch latch 133 has, in addition to the support stop 137, a further support stop 145, which extends essentially parallel to the support stop 137, but has a position turned away from it. This support stop 145 is assigned to the rear end 127b of the longitudinal slot 127 in the housing 126, with a distance which is matched to the cross-sectional width of the pin 129 on the engagement member 124. The support stop 145 of the snap catch 133 comes here with the pin 129 of the engaging member 124 in holding engagement as soon as the wing 102 assumes its closed position relative to the fixed frame 101, that is to say the opening closure in question is in its closing plane 128-128. An automatic locking of the wing 102 located in its closed position on the fixed frame 101 is also achieved in this way, which can only be canceled by holding both catch latches 132 and 133 together in the unlocked position for as long via the handle 141, until the pin 129 has passed the support stop 145. If the handle 141 is then released, the catch latch 132 automatically returns to its engagement position under the action of the spring force 134, although the catch latch 133 remains in the disengaged position against its spring force 135 until the pin 129 has reached the support stop 137. At this moment, the support stop 137 then engages behind the pin 129 of the engagement member 124 under the action of the spring force 135, so that it is fixed again between the two support stops 136 and 137.

In the lower transverse edge 133 of the snap latch 133, at least one locking trough 146 can be provided in the area between the two support stops 137 and 145, which can interact with the pin 129 of the engagement member 124. This makes it possible to keep the wing 102 relative to the fixed frame 101 in a night ventilation position that is smaller than the maximum response distance 140 required for the proximity switch 116 (FIG. 14).

Of course, it would also be conceivable to equip the second snap catch 133 in a manner similar to the first snap catch 132 with its own operating handle in order to be able to bring it out of its engaged position against the action of the spring force 135, if necessary. In this case it would then not be necessary to provide the driver stops 143 and 144 between the two snap catches 132 and 133. The actuating handle for the snap catch 133 could also be on another Position are provided, such as the actuating handle 141 for the snap catch 132. This would be advantageous if a common disengagement movement of the two snap catches 132 and 133 is to be made more difficult.

11 and 12 of the drawing it can still be seen that the housing 126 of the support and abutment bracket 123 and the snap catch 132 are designed symmetrically to a transverse plane 147-147, while the snap catch 133 has a symmetrical design to a longitudinal center line 148-148 Has. Using the same parts, it is hereby possible to assemble the support and abutment bracket 123 in such a way that the mechanical monitoring and / or securing device 122 is suitable either for a right-hand stop - as shown in the drawing - or for a left-hand stop. It is only necessary for this purpose, on the one hand, to implement the spring 134 relative to the catch trap 132 within the housing 126 and, on the other hand, to implement the catch catch with its spring 135 relative to the catch trap 132 in the housing 126.

In any case, it is expedient to provide the first snap catch 132 with flat recesses 149, in which the second snap catch 132 is accommodated and guided in a space-saving manner when both snap catches are inserted into the housing 126. A structurally simple configuration for the mechanical monitoring and / or securing device 122 is obtained if the housing 126 of the support and abutment bracket 123 is a one-piece molded part which is open on the rear, the two latches 132 and 133 with their springs 134 being opened through the rear and 135 can be installed and removed. The position securing and exact guidance of the snap catches 132 and 133 in the housing 126 is achieved by means of plug pins 150, which can be inserted into holes 150 in the housing wall and each extend through elongated holes 151 in the snap catch 132 and a window 152 in the snap catch 133.

As already mentioned above, the snap catch 133 contains its exact guidance in the flat recesses 149 on the snap catch 132. 15 shows a modified embodiment of a support and abutment bracket 153 in a representation corresponding to FIG. 12. This in turn has a housing 154 into which a longitudinal slot 155 opening at the end face 154a is formed, so that a lower housing leg 154b and an upper housing leg 154c are formed. In the upper housing leg 154c of the housing 154, three snap catches 156, 157 and 158 are accommodated, each of which is under the action of a spring force 159, 160 and 161 at its upper end.

Each of the springs 159, 160, 161 endeavors to place the catch latch 156, 157, 158 assigned to it with its free end transversely into the longitudinal slot 155.

The snap catches 156, 157 and 158 can each be formed by a collar bolt which is accommodated in its cross-sectionally adapted guide in the leg 154c of the housing 154 and with its free end is able to pass through a hole in the upper boundary wall of the longitudinal slot 155.

The free end of the bolt forming the catch latch 156 is provided with a run-on slope 162 which faces the open end 155a of the longitudinal slot 155 and can cooperate with a pin 163 which forms a wing-side engagement member.

The catch 163 is raised against the action of its spring force 159 and thereby brought out of the area of the longitudinal slot 155 by the pin 163 entering the longitudinal slot 155 and hitting the run-up slope 162. After the pin 163 has overcome the bevel 162, the snap latch 156 is pressed down again by the spring force 159 and then engages behind the bolt 163 with its support stop 164 facing away from the opening 155a of the longitudinal slot 155.

On the other hand, the bolt 163 bears against a support stop 165. which is located on the latch trap 157 and faces the opening 155a of the longitudinal slot 155. Between the two support stops 164 and 165, therefore, the pin 163 of the engagement member is fixed in such a way that the wing 102 is fixed relative to the fixed frame 101 at a distance which is adapted to the maximum response distance 140 for the proximity switch 116 (see Fig. 1 and 14).

The support stop 165 of the catch latch 157 can only be passed over in the direction of the closing plane 128-128 of the opening lock (see FIG. 14) if the catch latch 157 has previously been manually disengaged against the spring force 160. In order to make this possible, a slide 167 which can be actuated, for example by a push button 166, is built into the housing 154 and can be operatively connected via a molded wedge surface 168 to a correspondingly adapted wedge surface 169 on the catch latch 157.

By actuating the slide 167 by means of the push button 166, the catch latch 157 is raised against the spring force 160 via the wedge surfaces 168 and 169, so that the support stop 165 moves away from the area of the pin 163 and the latter can then run further into the longitudinal slot 155. There, the third catch latch 158 again has a run-on slope 170, which is inclined in the same direction as the run-on slope 162 of the catch latch 156. Therefore, the catch latch 158 can also be overcome against the action of the spring force 161 by the pin 163, so that the Pin 163 reaches the rear end 155b of the longitudinal slot 155. There, the snap latch 158 then acts under the action of the spring force 161 with a support stop 161 behind the pin 163 and thereby causes its position fixing when the wing 102 is in the closed position on the fixed frame 101.

So that the support stop 171 of the snap catch 158 and also the support stop 164 of the snap catch 156 the pin 163 of the engagement member to release the opening movement of the wing 102 relative to the fixed frame 101, the snap latches 158 and 156 must also be disengaged by manual actuation. For this purpose, the slide 167 which can be actuated manually, for example by means of the push button 166, has further wedge surfaces 172 and 173 which can come into operative connection with adapted wedge surfaces 174 and 175 of the catch latches 158 and 156. By pushing in the slide 167, the catch latches 156 and 158 with their support stops 164 and 171 are therefore lifted out of the area of the longitudinal slot 155 and thereby release them for the movement of the pin 163.

15, the two snap catches 157 and 158 can be designed so that they form a catch for the pin 163 in the longitudinal slot 155, which fixes an intermediate ventilation position for the wing 102, which with sufficient Exertion of force can be overcome in each of the two possible directions of movement.

The advantage of the support and abutment block 153 according to FIG. 15 lies in the fact that the effective areas of the three different latches 156, 157 and 158 are completely separated from each other on the outside, so that the mechanical monitoring and / or securing device 122 is rendered ineffective from the outside prevented, or at least considerably more difficult.

Another type of mechanical monitoring and / or securing device 222 is shown in FIGS. 16 to 21 of the drawing. Here, too, the support or abutment bracket 223 is rigidly attached to the room-side end face of the fixed frame 201 of a window, a door or the like. It is advantageously provided in the area of the closure side of the wing 202 at a parallel distance from the upright rollover circumferential surface 225 thereof.

The support or abutment bracket 223 is provided in its broad side facing the rollover circumferential surface 225 of the wing 202 with trough-like depressions 226a and 226b which are delimited from one another by a central web 226c which is approximately T-shaped in cross section. The web 226c carries a shaped piece 227 which has a support stop 228 on the one hand and an abutment stop 229 on the other hand. Support stop 228 and abutment stop 229 extend parallel to one another and are also parallel to the closing plane of the opening closure consisting of the fixed frame 221 and the wing 202.

The distance between the support stop 228 and the abutment stop 229 is bridged by guide surfaces 227a and 227b, which have an approximately V-shaped course inclined towards the closing plane 231, as can be clearly seen in FIG. 20.

By means of a threaded pin 227c, the shaped piece can be adjusted continuously in the longitudinal direction of the T-shaped web 226c on the support or abutment bracket 223 in the direction transverse to the closing plane 231 of the opening lock, in such a way that the distance between the support stop 228 and the abutment stop 229 from this closing plane is thereby simultaneously achieved 231 is changeable within certain limits. In any case, however, the support stop 228 on the support or abutment bracket 223 takes up such a distance 230 from the closing plane 231 of the opening closure - windows 201, 202 - that it exceeds the response distance of the proximity switch 16 associated with this opening closure.

The support stop 228 and also the abutment stop 229 on the shaped piece 227 or on the support or abutment bracket 223 lie in the inlet path of the actuating stop 224 mounted on the wing 202, which is formed, for example, by a pin with a round cross section. This stop 224 is seated on a slide 233, which is received in a longitudinal guide 234 of a housing 235. The housing 235 is on the wing 202 of the opening lock is mounted laterally next to the support or abutment bracket 223 mounted on the frame side.

The housing 235 with the guide 234 and also the slider 233 accommodated therein have an angular cross-sectional shape, so that they each lie on the room-side end face of the wing 202 with one leg, while the other leg lies laterally next to the rollover peripheral surface 225 of the same. The actuating stop 224 protrudes from one leg of the slide 233 through a longitudinal slot 236 of the housing 235, while an operating handle 237 is connected to the other leg of the slide 233 and passes through a longitudinal slot 238 in the housing 235. The operating handle is preferably designed as a handle button and is detachably and detachably connected to a tab 233a of the slider 233 via a stud screw 237a. For this purpose, the tab 233a of the slide 233 passes through the longitudinal slot 238 of the housing 235 to the front.

In its rear, the operating handle 237 is provided with a recess 237b in which a compression spring 240 is held by a pin 239. The pin 239 passes through the compression spring 240 in its longitudinal direction and holds it so that it protrudes with its half circumference from the recess 237b of the operating handle 237 and protrudes into the longitudinal slot 238 on the housing 235. One end of the compression spring is supported on an abutment 238a in the longitudinal slot 238, while its other end engages on a stop 237c of the operating handle 237, as can be seen in FIG. 19.

From the basic position shown in FIG. 19, the actuating stop 224 can be moved in the downward direction against the action of the compression spring 240 via the operating handle 237 acting on its slide 233, and zv, ar up to the lower end of the longitudinal slot 236. A shift up is, however, by the on the back of the operating Handle 237 prevents protruding stop tongue 237d, which protrudes into the longitudinal slot 238 of the housing 235 and engages in front of its upper end 238b.

After loosening the stud 237a, however, the operating handle 237 can be pulled off the tab 233a of the slide 233 and then put back on it in a position turned through 180 °. After the stud screw 237a has been tightened again, the adjusting stop 224 can subsequently be moved from the basic position shown in FIG. 19 towards the upper end of the longitudinal slot 236 against the restoring action of the spring 240, while moving downward through the stop tongue 237d is prevented.

Since the actuating stop 224 with its slide 233 and also the housing 235 are configured symmetrically to a transverse plane coinciding with the basic position, it is only necessary for an optional right and left stop to implement the operating handle 237 with the compression spring 240 in accordance with the desired actuation direction.

In the basic position shown in FIG. 19, the actuating stop 224 runs against the support stop 228 on the support and abutment bracket 223, as can be seen from FIG. 17. As a result, the wing 202 is blocked at a distance 230 from the closing plane 231 of the fixed frame 201 against a further closing movement. The distance 230 is dimensioned larger than the response distance of the proximity switch 16 (not shown) associated with the wing 202 and the fixed frame 201.

So that the wing 202 can be brought into the closed position relative to the fixed frame 201, the actuating stop 224 has to be displaced via the operating handle 237 at least so far against the restoring action of the compression spring 240 that it is in the region of the inclined guide Surface 227a reaches the fitting 227. If a closing pressure is then exerted on the wing 202, the actuating stop 224 slides downward, overcoming the restoring force of the compression spring 240, until the apex between the guide surface 227a and the adjoining, opposite-inclined guide surface 227b is reached. The actuating stop 224 now acts on the guide surface 227b, the compression spring 240 trying to push it in the upward direction. As a result, the wing 202 is moved over the guide surface 227b against the closing plane 231 of the fixed frame 201. At the end of this wing movement, the actuating stop 224 then occurs behind the abutment stop 229 on the fitting 227, as can be seen in FIG. 18, and thereby holds the wing 202 in the closed position on the fixed frame 201. In this operative position of the mechanical monitoring and / or securing device 225, the response distance of the proximity switch 16 (not shown) installed between the sash 202 and the fixed frame 201 is undershot, so that this becomes effective.

16 to 19 can still be seen that an angular tab 241 is integrally formed on the housing 235, which has such an arrangement and design that it supports the support and abutment bracket 233 in the closed position on the fixed frame 201 wing 202nd overlaps and covers on the room side.
