Abstract

The invention relates to a device for providing gap ventilation, for a window, a door or the like. Said device comprises a frame (1) and a leaf (2) as well as a drive rod fitting (6). Said drive rod fitting can be displaced between a closing position, an opening position and a gap opening position in which the leaf (2) can be opened to a gap ventilation position. The inventive device additionally comprises a movable gap opening arm (24) which is pivotally connected to the drive rod fitting (6). A displacement of the drive rod fitting (6) from the closing position to the opening position effects the displacement of the gap opening arm (24) along a trajectory. As a result, the gap opening arm (24) butts against a stop which ensures blockage in the direction of displacement. The gap ventilation device is also characterized in that a pivoting motion of the gap opening arm (24) is effected by further displacing the drive rod fitting (6) and thus the coupling element (25) from the opening position into the gap opening position, interacting with the stop. The gap opening arm (24) thereby opens the leaf (2) to a gap ventilation position.

Description

Night ventilation device

The invention relates to a gap ventilation device according to the preamble of patent claim 1.

Gap ventilation devices are used to set a ventilation position of a window or a door. The wing of the window or door should be opened a more or less large gap and held in the set position.

From DE 82 18 084 U1 a gap ventilation device has become known in which a locking member of the connecting rod fitting interacts with the V-shaped end of a gap opening arm in such a way that the pivotable and slidably articulated on a base plate

The gap opening arm holds the unlocked sash on the locking element when the so-called gap ventilation position of the connecting rod fitting is reached. The gap opening arm pivots perpendicular to the folding plane and - supported by a corresponding spring load on the gap opening arm - causes the sash to be set apart from the frame. The movement of the limit lever is limited by a side stop.

DE 37 19 040 C2 sees as a further development of DE 82 18 084 IM a gap ventilation device with increased holding force and greater

Night vent. This is essentially achieved in that the compression spring is replaced by a tension spring lying in the plane of the articulation point of the gap opening arm, and in that the stop is arranged at a distance to limit the opening movement of the gap opening arm. The stop plunges into a side-open recess of the limiting arm, which is displaced longitudinally by the locking member, so that it can be pivoted further. A disadvantage of the night ventilation devices of the aforementioned type is that the arrangements are very complex and yet a reliable holding of the wing in the spring-loaded V-shaped recess of the night opening arm is not guaranteed. At the same time, a large installation space is required for the assembly of the gap ventilation device, which is not always the case, particularly in the depth of the rebate area transverse to the sash and frame level.

Other night ventilation devices, such as those from DE 80 15 677 U1. Known ones are based on the interaction of a stop part fixed to the frame, against which a locking pin of the connecting rod fitting starts after the sash is unlocked, in order to ensure that the sash is forced to move away from the frame.

The locking pin engages behind a closing edge of this known gap ventilation device and prevents the wing from opening.

A disadvantage of these designs is in addition to the complicated

Operation the only relatively small opening width, which only allows insufficient ventilation of the room.

From DE 38 20 755 A1 an opening limiter for windows has become known in which a locking pin of the

Espagnolette fitting cooperates with a limiting arm which is pivotally and displaceably held on a base plate in the direction of movement of the locking pin. The limiting arm has on its front longitudinal side in the opening direction a recess in which the locking pin between the

Close position is present. In the open position, the firing pin is assigned a recess distant from the anchoring point of the limiting arm of a positive extension of the limiting arm. In this position the sash can be swiveled, but is now limited in its maximum swivel opening position by the opening limiter.

The invention has set itself the task, starting from the

DE 38 20 755 A1 to create an opening limiter which allows a large opening width of the wing with simple operation of the drive rod fitting.

The object is achieved according to the invention by the features specified in the characterizing part of claim 1. An assignment of the gap opening arm to the espagnolette fitting is effected, which permits a forced opening movement of the wing controlled by the actuation of the espagnolette fitting, which is dimensioned much larger than would be possible, for example, by locking members movable only in the longitudinal direction. For this, only a few components are required, which can be arranged in a simple manner concealed for the user in the rebate area of the wing and or of the frame.

It can first be converted into a rotary opening position by means of the arrangement according to the invention of the sash of the window or the door, and the desired gap opening position can be set therefrom by advancing the connecting rod fitting.

In a further embodiment, the invention provides that the effective length of the gap opening arm is dimensioned approximately half as large as the entire stroke length of the connecting rod fitting between the closing and opening positions A, C. This causes the opening movement of the Limiting arms only after overcoming about half the stroke length of the connecting rod fitting begins, i.e. after reaching the rotary opening position. This ensures, on the one hand, that all locking points of the connecting rod fitting have been unlocked and, on the other hand, that the sash is in the rotational opening position. The rotary opening position is usually indispensable, for example, for cleaning the wing's glass filling.

A further embodiment of the gap ventilation device provides that the gap opening arm is arranged as a limiting arm on the connecting rod fitting in a non-detachable and pivotable manner, its end having a coupling point for connection to the fixed stop. In this exemplary embodiment, the limiting arm is part of the connecting rod fitting, so that the limiting arm is assigned to the connecting rod fitting in any case. The limit arm is used together with the

Espagnolette fitting moved and interacts with the fixed stop after the distance of the guide slot has been overcome. This also ensures simple mounting of the gap ventilation device on the wing, since this is provided in one piece with a corresponding component of the connecting rod fitting.

A particularly preferred embodiment provides that the stop has a backdrop forming a fulcrum, the outer contour of which forms a segment of a circle and the limiting arm forms at its free end an approximately semicircular hook which - acting as a sliding block - interacts with the backdrop. After the first distance, which represents a partial stroke of the connecting rod fitting, the limiting arm is inserted into the link with the semicircular hook and the limiting arm is forcibly pivoted about the free end due to the shape of the semicircular hook and the link. In order to secure the wing relative to the frame, it is further provided that the backdrop forms an undercut area which the limiting arm engages behind in the open position. With this configuration, the limiting arm with its semicircular hook can be pushed past the half-cylinder and, after forcibly pivoting about the pivot point formed by the link, engages behind this half-cylinder and prevents an undesired opening or other movement of the wing due to the positive connection.

A further embodiment of the gap ventilation device provides that the coupling point of the limiting arm interacts as a positive connection with a locking pin of the connecting rod fitting. As a result, commercially available hardware components that are already in use can be used together with the gap ventilation device.

Further advantageous configurations result from the further subclaims and the drawings. Show it:

The window shown in FIG. 1 and provided with a gap ventilation device consists of a frame 1 to which a wing 2 is articulated, which can be opened in rotation about a vertical axis 3. A connecting rod fitting 6 is arranged in a groove in the rebate surface of the wing 2 in a manner known per se, which can be adjusted into three different switching positions by actuating the operating handle 7. In the first switching position - the closed position A - the wing 2 is locked to the frame 1 by means of locking members or locking pins arranged on the connecting rod fitting 6. In the second switching position - the rotary opening position B - the wing 2 can be opened in a rotary position and in the third switching position - gap opening position C - gap opening can be opened into a gap ventilation position. The

Switch positions A, B, C are each set, for example, by turning the operating handle 7 by 90 °. As can be seen in FIG. 2, the drive rod fitting 6 is essentially formed from a faceplate or a cover bracket 10 and a drive rod 11 which is guided longitudinally displaceably underneath. The faceplate or the cover bracket 10 cover the drive rod 11 located in the groove 12 of the rebate surface 13. In the illustrated

An exemplary embodiment shows a connecting rod component in the form of a corner deflection 14. On the lower horizontal leg

15 of the corner drive 14, a locking pin 16 with a cylindrical shape can be moved back and forth by the drive rod 11 in the longitudinal direction of the drive rod fitting 6. The locking pin

16 extends through the slot opening 17 in the cover bracket or the faceplate 10.

The gap ventilation device 21 visible in FIG. 3 is arranged in the lower horizontal frame leg 20 of the window. The

The gap ventilation device 21 is fastened on a rebate surface 22 of the frame 1 and has a limiting arm 24 projecting in front of the frame visible surface 23.

As is clear from FIG. 2, the limiting arm 24 can be pivotally connected to the locking pin 16 via a coupling point 25. The limiting arm 24 is, as shown in particular in FIGS. 4a to 4c, together with the locking pin 16 arranged on the connecting rod fitting 6 from the closed position A according to FIG. 4a, into the rotary opening position B (FIG. 4b) and into the gap opening position C (FIG. 4c) to be transferred. The locking pin 16 indicated here travels a stroke length Y. In the closed position A, the limiting arm 24 is retracted into the position shown in FIG. 4a by the positive connection of the coupling point 25 and the locking pin 16. In this situation, the most

Limiting arm 24 fixed guide and holding pin 26, 27 comes near the end of the guide slots 28, 29. As is clear from FIG. 4a, the guide slot 29 is a straight one Longitudinal slot formed, which is provided on its underside with a step 30. The guide slot 28, on the other hand, has an arcuate section 31, the center point 32 of which coincides with the center point of the pin 26, which it occupies in the rotational opening position B. The guide slot 28 is also provided on the back of the base plate 33 with a step 34.

The step countersinks 30, 34 serve, as the section along the line IVd using the example of the guide pin 27, to accommodate the

Head 35 of the guide pin 27. As is also clear from FIG. 4d, a disk 36 is provided coaxially to the guide pin 27 between the base plate 33 and the limiting arm 24, which spacers the limiting arm 24 from the base plate 33.

When the locking pin 16 is shifted from the closed position A shown in FIG. 4a to the rotary opening position B (FIG. 4b), the limiting arm 24 is displaced by the distance X. Here, the guide pin 26, as shown in FIG. 4a, is also displaced by the distance X in the guide slot 29. In the rotational opening position B, the leaf 2 can be pivoted about the vertical axis 3 without any problems, the locking pin 16 being disengaged from the coupling point 25.

When the wing 2 is closed from the rotary opening position B, the locking pin 16 returns to the coupling point 25 via the funnel-like guide surfaces 40 balanced in the guide slots 28, 29. The limiting arm 24 is prevented in the rotational opening position B of the connecting rod fitting 6 from rotating about the guide pin 26 by the guide pin 27. In order to be able to execute this rotary movement, as shown in FIG. 4c, the locking pin 16 must also be in the rotational opening position B of the

Teibstangenbeschlag 6 are shifted into the gap opening position C. If the locking pin 16 is moved further beyond the distance X, the guide pin 26 comes against the end of the guide slot 29 which acts as a stop 43, the limiting arm 24 being caused by the further displacement of the

Locking pin 16 is guided on a circular path around the guide pin 26. The limiting arm 24 is therefore forcibly pivoted about the guide pin 26, the guide pin 27 being guided in the section 31. In order to facilitate the rotary movement of the limiting arm 24, the stop 43 is offset parallel to the

Direction of movement of the locking pin 16 arranged. As a result, when the stop 43 is reached, a moment acts on the limiting arm 24, which allows a simple pivoting movement without frictional engagement at the stop.

The stop 43 acts as locking only in the direction of displacement of the limiting arm 24; a rotary movement of the limiting arm 24 is possible, the stop 43 forming a pivot bearing.

4c, the longitudinal center line 41 of the limiting arm 24 and the longitudinal central axis 42 of the connecting rod fitting 6 are therefore spaced apart by the effective length L of the limiting arm 24. The limiting arm 24 is rotated approximately 90 ° from its starting position, almost perpendicular to the connecting rod fitting.

This alignment prevents any forces acting on the wing 2 from leading to a displacement of the locking pin 16 and thus of the entire drive rod fitting 6. The effective one Length L of the limiting arm 24 is dimensioned approximately half as large as the entire stroke length 4 of the connecting rod fitting 6. This allows the 90 ° position of the limiting arm 24 already mentioned in the gap opening position C, but also enables the rotary opening position B to be set from the

Closed position A.

To secure the locking pin 16 in the gap opening position C, the coupling point 25 is provided with a circular ring section 45 which can be pivoted about the central axis 44 of the coupling point 25. As can be seen from FIG. 4b, the circular ring section 45 is arranged such that it can pivot relative to the limiting arm 24. For this purpose, guide pins 46 attached to the underside of the circular ring section 45 engage in corresponding links 47. The circular ring section 45 is rotationally inhibited with respect to the closing pin 16, which can be achieved, for example, by a

Inside of the circular ring section 45 attached holding mandrel 48 can be reached. When pivoting the limiting arm 24 from the position shown in FIG. 4b, in which the longitudinal center lines 41, 42 of the opening limiter 21 and the connecting rod fitting 6 run parallel, into the gap opening position C shown in FIG. 4c, in which the longitudinal center line of the connecting rod fitting and the limiting arm Stand almost perpendicular to each other, the circular ring section 45 closes the opening 49 of the coupling point 25. As a result, the locking pin 16 is encompassed in a form-fitting manner until the connecting rod fitting 6 moves out of the gap opening position C into

Rotary opening position B is returned.

It is essential in the embodiment according to FIGS. 4a to 4d that the limiting arm 24 can be carried along by the drive rod fitting 6 along the entire stroke length Y of the driving rod fitting 6, and that the longitudinal center line 41 of the limiting arm 24 and the longitudinal center line 42 of the connecting rod fitting 6 in 4a and 4b have the parallel alignment position shown. The longitudinal center line 41 denotes less the geometric longitudinal center than the one on which both the coupling point 25 and the pivot bearing of the limiting arm 24 lie.

In the exemplary embodiment shown in FIG. 5, the limiting arm 24 is guided in a longitudinally displaceable manner by a laterally flattened guide rivet 60 in the guide slot 29. The guide slot 29 is formed like a keyhole and in the region of the cylindrical bore 61 to which the width of the

Guide rivets 60 matched elongated slot section 62, dimensioned such that the guide rivet 60 is pivotable in the bore 61. The limiting arm 24 is rotatably connected to the guide rivet 60, so that the limiting arm 24 is rotatably mounted on the base plate 34 in the closed position A shown in FIG. 5. After covering the distance X in which the longitudinal center lines 41 and 42 of the limiting arm 24 and the connecting rod fitting 6 run parallel, the guide rivet 60 abuts the edge of the bore 61 which acts as a stop. If the locking pin 16, not shown here, is moved further from the rotary opening position B, it is sufficient As practice has shown, a small pressure, for example generated by the seal between frame 1 and wing 2, on wing 2 about the longitudinal center lines 41, 42 of limiting arm 24 and drive rod fitting 6 should be spaced apart or pivoted so that the over the locking pin 16 applied

Torque causes a rotation of the limit arm 24.

Of course, this can also be achieved by additional measures, for example by hitting a spring element 64 attached to the limiting arm 24 against one

Stop 65 on the base plate 34, so that the limiting arm 24 is given away slightly. The spring element 64 can, as shown in FIG. 5, be formed in one piece with the limiting arm 24 by cutting it. The stop 65 is to be arranged so that the spring element 64 hits it before the guide rivet 60 fully inserts in the bore 61. The spring element 64 is at

Swiveling the limiting arm 24 from the gap opening position C loads and causes the coupling point 25 to lean against the locking pin 16. The opening 49 of the coupling point 25 can be provided by the circular ring section 45 known from FIG. 4c for the positive connection with the locking pin 16.

In the exemplary embodiment according to FIGS. 6a to 6d, the limiting arm 24 is pivotably articulated on the drive rod 11 of the drive rod fitting 6 via a pin 70. For a better overview, the representation of the connecting rod fitting 6 has been omitted in FIGS. 6a and 6b. If the connecting rod fitting is transferred from the closed position shown in FIG. 6a to the rotary opening position B shown in FIG. 6b, the longitudinal center lines 41 of the limiting arm 24 and the longitudinal center line 42 of the connecting rod fitting 6 are congruent.

The limiting arm 24 forms at its free end 71 an approximately semicircular hook 72 which is closed in the direction R towards the interior of the room. The frame 1 - not shown here - is assigned a frame part 73 which has a stop 74 for the limiting arm 24. The stop 74 forms a backdrop 75 with a shape complementary to the semicircular hook 72, so that its outer contour 76 forms a segment of a circle transverse to the direction of displacement of the limiting arm 24. After the distance X has been overcome, the semicircular hook 72 reaches the area of the backdrop 75.

If the espagnolette fitting 6 is moved further from the switching position shown in FIG. 6b in the direction of the gap opening position C according to FIG. 6c, the semi-circular block acting as a sliding block follows Hook 72 of the backdrop 75, which forms a pivot point 77 for the limiting arm 24. The longitudinal central axis 41 of the limiting arm 24 is rotated relative to the longitudinal central axis 42 of the connecting rod fitting 6 until they assume the rectangular position shown in FIG. 6c in the gap ventilation position with respect to one another. The limiting arm 24 with the semicircular hook 72 encompasses an approximately quarter-circular section 78 of the b-shaped web 79, which forms the inner contour in the region of the semicircular link 75. The web 79 forms at its end the quarter cylinder 78, the flat surface 80 of which runs parallel to the direction of displacement of the connecting rod fitting 6 and at right angles to the direction R, so that the semicircular hook 72 can pass through the web 79 when the different switching positions are set. The web 79 forms the inner contour of the link 75 through the section 78 an undercut area

81, which the limiting arm 24 engages behind with the hook 72 in the open position C. The link 75 therefore not only forms the fulcrum 77 for the limiting arm 24, but also serves as a positive connection of the limiting arm 24 with the frame part 73 and is effective as a stop 74.

When the espagnolette fitting 6 is reset from the gap opening position C, the sash 2 is forcibly returned to the frame 1 at the same time. In order to ensure a defined position of the limiting arm 24, the

A device 70 is also provided for the pin 70, which resets the limiting arm 24, at least in the rotational opening position B, into the parallel alignment position of the longitudinal center lines 41, 42 shown in FIG. 6b. This can be done, for example, by an energy storage device in the form of a spring, which is on the pin

70 is arranged and engages the limiter arm 24 with a leg or the like. As can be seen in particular from FIG. 6d, the limiting arm 24 is produced from a flat metal strip or the like and is fastened on a collar 82 of the pin 70. As a result, the limiting arm 24 is spaced from the faceplate or the cover bracket 10 and forms a mushroom head. With that, he engages

Limiting arm 24 in the closed position an undercut 83 of the frame part 73, as can be seen from FIG. 6a. In this case, a radius 85 embodied on the limiting arm 24 coaxially to the pivot axis 84 on the connecting rod fitting lies in a complementary pocket 86 of the frame part 73

Slit opening position B, a roof 87 covers the backdrop 75, so that on the one hand the penetration of dirt or the like is prevented, but on the other hand a prying out of the limiting arm 24 from the backdrop 75 is prevented. Like the backdrop 75, the pocket 86 is dimensioned larger in height 88 than the limiting arm

24, in order to be able to compensate for any changes in the relative position of the wing 2 relative to the frame 1. If the wing 2 settles, for example due to wear on the hinge parts forming the vertical axis 3, the limiting arm 24 is displaced downward within the pocket 86 in the drawing. To one

To make relative alignment of the frame 1 and the sash 2, a ramp surface 89 is therefore provided on the frame part 73, which cooperates with a ramp 90 arranged on the drive rod fitting 6 and thus additionally ensures the necessary distance of the drive rod fitting 6 from the frame part 73.

The run-up surface 89 is inclined in a manner known per se as a wedge surface against the opening direction of the wing. The casserole 90, as shown in FIG. 6d, is provided as an additional component in the form of a disk coaxial with a fastening bore 91 of the drive rod fitting.

In addition to the illustrated exemplary embodiments, it is of course also possible for the mushroom head pin 70 to form Pin is formed as a separate second pin and therefore it has the functions of locking and supporting the limiting arm 24 different components (Fig. 6d).

7, the frame part 73 is shown in a plan view. In

6d that the width 92 of the locking engagement 93 is matched to the collar 82 of the pin. The collar 82 is eccentric to the axis of the pin 70, so that the pressure behavior of the collar 82 for the closing engagement 93 can be adjusted via a hexagon collar 94. The frame part 73 is designed as a molded part and can be produced from metal by die casting or the like.

Finally, it should also be pointed out that the link 75 can taper towards the end, that is to say, in the opening area of the semicircular hook 72, it has a width 95 which is larger than the width 96 which occurs in the rear area of the link 75. This is intended to ensure easy insertion of the limiting arm 24 into the link 75, while in the gap opening position C the limiting arm 73 is to be accommodated in the link 75 closely and without play. The range of motion of the wing 2 in the gap opening position C is restricted and undesired movements of the wing 2, which can lead to the "rattling" of the wing 2, are prevented.

In the exemplary embodiment of the opening limiter 21 shown in FIGS. 8a to 8d, the limiting arm 24 is pivotably articulated on the drive rod 11 via the coupling point 25 in the form of a connecting rivet 100. The limiting arm 24 is thereby carried along the entire stroke length Y with the drive rod.

The limiting arm 24 is first shifted from the closed position A shown in FIG. 8a into the rotary opening position B shown in FIG. 8b. In doing so, the Coupling point 25 opposite end of the limiting arm 24 in the region of an elongated hole 101 of a fixed frame part 102 which has a lateral opening 103. The limiting arm 24 engages in the elongated hole 101 with a pin 104 with a square or rectangular cross section, which is shown invisibly in FIG. 8c. The cross section of the pin 104 is designed so that it almost corresponds to the width of the elongated hole 101. The opening 103 is provided with funnel-like guide surfaces 105 which are intended to facilitate insertion of the pin 104 from the rotational opening position B back into the elongated hole 101. When the wing 2 is open for rotation, the connecting rod fitting 6 is pivoted together with the limiting arm 24 out of the fold surface shown in FIG. 3, so that when the pivot 104 is pivoted in again, it must be inserted again into the elongated hole 101.

On the limiting arm 24, a link 106 is rotatably fastened via a rivet 107, so that the anchoring point 108 lies next to the longitudinal center line 41 of the limiting arm 24. The end of the link 106 opposite the attachment point 108 is longitudinally displaceable in a slot 109 via a guide rivet 110 in FIG

Movable in the direction of the drive rod 11. After overcoming the distance X from the closed position A, the guide rivet 110 abuts the end 111 of the slot 109 acting as a stop, so that the link 106 - acting as a toggle lever - triggers a pivoting movement of the limiting arm 24. For other people too

To prevent exemplary embodiments of the link 106 and the limiting arm 24, in which the coupling point and guide rivet 110 lying on a common longitudinal center line 42 cannot generate a moment for the rotary movement of the limiting arm 24, the anchoring point 108 is opposite the opening direction of the wing 2 next to the longitudinal center line 41 of the limiting arm 24 arranged. As a result, a torque is applied to the Limiting arm 24 causes, which leads to a rotation about the coupling point 25.

In order not to impede the pivoting movement of the limiting arm 24 in the elongated hole 101, a keyhole-like extension 112 is provided in the end region of the elongated hole 101, to which the pin 104 is assigned in the switching position C, which permits a rotary movement of the square cross section of the pin 104. In the rotated position of the square cross section of the pin 104, it cannot be transferred back into the narrow region of the elongated hole 101.

8d shows the spatial arrangement of the components of the opening limiter 21 which are shown as visible in FIG. 8c irrespective of the actual spatial arrangement. The frame part 102 assigned to the fixed frame 1 consists of an approximately U-shaped sheet metal part, which in the area of the elongated hole 101 has a bent portion 115 pointing in the direction of the connecting rod fitting 6. This creates a space behind the frame part 102, which the head 116 of the

Pin 104 offers enough space so that it does not drag on the rebate surface 22 of the frame. The limiting arm 24 has a bent portion 117 which is directed away from the faceplate 10 in order to be able to arrange the link 106 arranged below it between the limiting arm 24 and the faceplate 10. The link 106, on the other hand, is designed as a flat sheet metal section and only has the bores necessary for receiving the rivet 107 or the guide rivet 110.

In addition, it should also be noted that the distance X is dimensioned slightly larger than the stroke length between the closed position A and the rotary opening position B. To avoid unnecessary Forcing and as tolerance compensation, a tolerance distance T is provided which ensures that the rotary opening position B is set.

In addition, it should also be pointed out that in the last-mentioned exemplary embodiment, the attachment point 108 also relates to the

The longitudinal center line 113 of the link 106 is laterally offset in order to be able to ensure a parallel position of the link 106 to the connecting rod fitting 6 in the closed position A.

9a and 9b show a securing device 150 for a

Gap ventilation device 21. The securing device 150 consists of a frame part 151 assigned to the rebate surface 22 of the frame 1, on which a securing arm 152 is pivotably articulated via a pin 153. Furthermore, the securing device 150 has a drive rod 11 of the

Espagnolette fitting 6 longitudinally displaceable locking member 154 that is formed from an approximately Z-shaped sheet metal part 155. The free end of the sheet metal part 155, which is spaced apart from the faceplate or the cover bracket 10, forms a fork-shaped locking engagement 156, while the opposite end of the sheet metal part 155 is guided in a longitudinally displaceable manner by a pin 157 on the faceplate or the cover bracket 10. For this purpose, the cover bracket or the faceplate 10 has an elongated hole 158, into which a section 159 of the leg 160 of the sheet metal part 155 assigned to the cover bracket or the faceplate 10 is immersed. The pin 157 is in

Extended in the direction of the frame 1 and assigned as a mushroom head pin 161 in the closed position A to a bolt engagement 162 arranged on the frame part 151.

The securing arm 152 is also bent and has one

S shape. A further pin 166 provided with a mushroom head is provided on the leg 165 bent off to the frame part 151. The locking arm 152 is in position via a spring 167 aligned, in which the longitudinal central axis 168 is aligned with the longitudinal central axis 169 of the frame part 151. If the espagnolette fitting 6 is moved to the gap opening position C, the wing 2 and thus also the longitudinal central axis 42 of the espagnolette fitting 6 is forcibly separated from one another by the gap ventilation device 21. The

Fig. 9c shows in a schematic representation that the sheet metal part 155 - due to the section 159 locked against rotation - on the drive rod fitting 6, not shown here, maintains its original orientation. The securing arm 152, on the other hand, becomes the gap ventilation device 21 and the like by the gap opening movement

Gripping around the pin 166 by the fork-shaped section 156 pivoted about the axis defined by the pin 153. The effective length 170 of the securing arm 152 corresponds approximately to the length of the limiting arm 24, but is preferably of somewhat longer design.

The securing device 150 acts predominantly passively, since the wing 2 is forcibly switched off via the gap ventilation device 21. By means of the securing device 150, the wing 2 can additionally be secured in the gap ventilation position on the frame spar opposite the gap ventilation device 21, whereby it is of course expedient that the gap ventilation device 21 is not only arranged on the opposite frame spar, but also approximately the same distance from the corner region of the Frame 1 has as the gap ventilation device 21. By the

Safety arm 152 prevents the wing 2 from being pressed inwards by wind forces or impermissible handling. The configuration of the pin 166 as a mushroom head pin reliably prevents the securing arm 152 from being levered out of the latch engagement 156. Due to the bolt engagement 162, which interacts with the mushroom head pin 161 in the closed position A, the security of the entire window is increased. Finally, it should be pointed out that the arrangement of such a gap ventilation device 21 is preferably carried out in an area 175 (FIG. 1). If the gap ventilation device 21 is arranged in this area, the securing device 150 can be arranged on the opposite horizontal frame spar. The closer the gap ventilation device 21 is arranged from the corner region of the frame 1 or wing 2 removed from the axis 3 to the center of the wing, the more the wing 2 is opened by the gap ventilation device 21. However, the balance of power also changes, so that the operation of the

Espagnolette fitting 6 is difficult. The gap ventilation device 21 can of course also take place on the vertical frame or wing leg opposite the axis 3. The securing device 151 can be provided on a horizontal frame leg, the

The securing arm 152 naturally extends less far than the limiting arm 24 due to the smaller distance from the axis 3.

The illustrated exemplary embodiments are based on a wing 2 which can be pivoted about a vertical axis 3. This is the

Wing 2 is designed as a pure rotating wing. Of course, it can also be provided that instead of the vertical axis 3, a pivoting movement about a horizontal axis, for. B. is provided on the lower horizontal frame spar. Even with such pure tilting wings can be a simple

Slit opening position C can be set.

It is also possible to provide that the gap ventilation position does not represent a pivoting about the axis 3, but that the wing 2 is pivoted about a second about a tilt axis perpendicular to the axis 3. For this purpose, only appropriate latch interventions are to be provided on the lower or upper horizontal frame rail which hold the sash on the frame in the gap ventilation position, e.g. B. a toggle latch device.

With the configuration of the securing device 150 according to FIGS. 9a to 9c, both right and left wings 2 can be provided, since all components are aligned symmetrically on the longitudinal center lines. In the gap ventilation device 21, however, different frame parts 73, 102 are to be provided for windows opening to the right and left. However, this can be dispensed with if the gap ventilation device 21 is provided for the lower horizontal frame spar in the window shown in FIG. 1 and is attached to the upper horizontal frame spar with a wing opening to the left. Then the closing direction of the espagnolette fitting 6 is the same.
