Abstract

A fitting for doors, windows or the like including an espagnolette or espagnolette lock fitted in a case in which is housed a control mechanism permitting the activation of at least one operating rod and an electrical blocking device. In order to avoid significant modifications to the standard espagnolette or espagnolette lock, the electrical blocking device is in the form of a separate assembly placed either at any place at the front edge of the leaf of the door or window, or aligned with the prolongation of and coupled with the case of the espagnolette or espagnolette lock.

Description

The invention relates to a fitting for a door, window or the like, comprising, on the one hand, a cremone bolt or cremone bolt provided with a housing in which is housed a control mechanism making it possible to actuate at least one operating rod and , on the other hand, an electric locking device provided with motor means for driving blocking means moving perpendicularly relative to the operating rod or rods, this, in the terms of the preamble of claim 1.

The present invention will find its application, more particularly, in the field of building hardware.

Usually, the bolts or bolts-locks for door, window or the like consist of a housing secured to a headrest and in which is housed a control mechanism allowing the user to actuate one or more locking elements.

As a general rule, the latter consist of one or two operating rods extending on either side of the housing and sliding behind the headrest of the cremone bolt or cremone bolt. These rods are provided with one or a plurality of locking members, for example bits or rollers, emerging from said headrest through slots machined therein, so as to cooperate with strikes integral with the sleeping frame of the door, window or the like.

In the context of cremone bolts, these are provided with a key element making it possible to immobilize in translation the rod or rods or to annihilate the action of the user on an operating member, such as a crutch, button or other. In addition, the control mechanism of these bolts and bolts also makes it possible to actuate another locking element and, in particular, a latch bolt.

In certain cases, it may prove to be particularly advantageous to ensure the remote control of the locking of an opening leaf provided with such a lever or lever-lock.

To this end, cremones or cremone bolts have been designed provided with an electrical locking device comprising motor means making it possible to actuate directly or by means of a secondary connection part, one or more locking elements. Thus, these motor means, consisting of either an electric motor or an electromagnet, can control the movement of a latch bolt and / or one or more rods.

In general, these electrical locking devices have a relatively large size due to the motor means whose power must be sufficient to cause the displacement of the locking elements. Therefore, the cremone bolt or bolt lock, containing said motor means, has dimensions greater than a standard casing and requires a deeper and wider notching in the edge of the opening to allow its embedding. However, such specific notching requires the use of a tool different from that usually used. Note also, that the amount of the opening must have a sufficient thickness allowing the notching

Furthermore, in the context of locks and bolts, motor means operating on the blocking system are known, for example the key element, for immobilizing the locking elements. Such drive means require less power to impart translation or rotation to a blocking element when locking or locking the opening of a door, window or the like.

However, this reduction in power of the motor means does not make it possible to resolve the aforementioned problems. Indeed, whatever the size of an electric motor or an electromagnet, their insertion in the housing of a lock-bolt inevitably generates an increase in the size of this housing. This results in a wider cut and, in any case, deeper in the edge of the opening.

In certain cases, the electrical locking device and, in particular, the drive means are located on the door leaf and act on the control mechanism embedded in the edge of the this last. This solution only partially solves the problem since it requires the machining of the internal face of said opening.

Another disadvantage that presents, in general, the association of an electrical locking device with a cremone bolt or cremone bolt consists in that a large number of the parts of the latter's control mechanism necessarily have a particular configuration to authorize the integration of the driving means.

It is therefore necessary to manage a heavier production and a larger stock to have cremone bolts or bolts-locks, some of which are provided with an electrical locking device and others which are not.

It is also known, according to the prior document EP-A-0173987, an electrically controlled auxiliary locking device associated with a cremone bolt or cremone bolt.

In fact, this auxiliary locking device consists of an electromagnet provided with a locking pin capable of cooperating with a control member actuating one or more of the locking elements of the lever or lever-lock. This control member can be an easel acting on a tilting bolt integrated in the front edge of the door or window.

However, this auxiliary locking device can also be associated with the main housing containing the control mechanism of said cremone bolt or cremone bolt.

However, to allow this electromagnet to perform the function assigned to it, it must necessarily be fixed securely either to the main casing of the cremone bolt or cremone bolt, or to one of the housings containing an element lock. Consequently, the combination of such an auxiliary locking device requires a specific arrangement of the cremone bolt or cremone bolt. This deviates from the standard characteristics and requires additional manufacturing and storage management.

Furthermore, because of its arrangement perpendicular to the operating rods, the electromagnet imposes a notching of increased depth of the edge before the opening welcoming the lever or lever-lock. However, the present invention proposes, precisely, to limit the importance of this notching.

In addition, the direct and unique action of the locking pin on any control member has certain drawbacks. In particular, the actions of a haddock on this control member are passed on, in full, to said blocking pin whose resistance is relatively limited.

However, if the assembly resists these actions, it is likely that the locking pin has undergone such a deformation that it puts the electromagnet out of use. However, under these conditions, no solution is offered to the user to unlock the door or window again.

The object of the present invention is to remedy all of the aforementioned drawbacks.

The invention as characterized in the claims solves the problem of creating a fitting for door, window or the like comprising, on the one hand, a cremone bolt or cremone bolt provided with a housing integral with a headrest and in which is housed a control mechanism making it possible to actuate at least one operating rod, and, on the other hand, an electrical locking device which is, on the one hand, in the form of a separate assembly from the cremone bolt or cremone bolt, and placed, either at any place located in the longitudinal extension and on either side of the housing, or in the immediate extension of the latter, in an adjoining manner at one of the ends thereof, and secondly, having blocking means, subject to motor means and electrical control members, and cooperating with the control mechanism and / or the operating rod, said blocking means being constituted s by a slide moving perpendicular to the longitudinal axis of the operating rod, and having a front end cooperating, in the locked position, with said control mechanism and / or the operating rod, said motor means being dissociated from said blocking means and acting along an axis perpendicular to the movement of said slide.

The advantages obtained thanks to this invention consist essentially in that the location of the electrical locking device with respect to the case of the cremone bolt or cremone bolt prevents a deeper and wider notching of the amount of the opening. Only an additional longitudinal notching is necessary, which allows the use of standard tools. Note that this additional notching can be carried out either as an immediate extension of that arranged for the cremone bolt or cremone bolt, or at any location on the edge of the opening.

Another advantage obtained thanks to this invention consists in that the association of the electric locking device with a cremone bolt or cremone bolt does not generate any more modifications of the constituent elements of the control mechanism and hardly any modifications of the box containing the latter. Therefore, it is advantageous to be able to adapt the electrical locking device to any lever or lever-lock already installed, with very few modifications to be made except the longitudinal enlargement of the notching.

FIG. 6 represents a plan view of the guide element illustrated in FIG. 5.

Reference is made more particularly to FIGS. 1 and 2.

The fitting 1, for door, window or the like, in accordance with the invention, comprises a cremone bolt or locking bolt 81, formed essentially of a housing 2 attached to the internal face of a headrest 82 (not shown) and intended to be embedded in the edge of an opening.

The housing 2 serves as a housing for a control mechanism 3 whose function consists in transmitting the action of a user on any control member, for example, a crutch or a key element, on one or more locking elements .

Thus, this control mechanism 3 makes it possible to actuate at least one operating rod 83 extending on one side or the other of the housing 2. This operating rod 83 carries, as a general rule, a plurality of members locking, such as rollers, bits or the like, which are able to cooperate with strikes arranged on the frame.

In the context of a locking lever, the control mechanism 3 also makes it possible to actuate another locking element and, in particular, a latch bolt 4.

When a cremone bolt or locking bolt is provided with two operating rods extending on either side of the housing 2, these are moved by the action of the control mechanism 3, either in opposite directions, l 'one in relation to the other, in an identical sense. In the latter case, the said operating rods are generally connected by an easel 5 or other, housed in the housing 2 and on which the control mechanism 3 acts.

According to the invention, the fitting 1 comprises an electrical locking device 6, controlled remotely and the function consists in immobilizing, in the locked position and after closing the opening of the door, window or the like, a mobile member of the control mechanism 3 and / or the operating rod or rods 83 of the lever or lever-bolt 81.

Advantageously, this electrical locking device 6 is located in the longitudinal extension of the housing 2 and is in the form of a separate assembly consisting of a second housing 7.

This latter contains, more precisely, electrical control members 8 actuating motor means 9 ensuring the driving of blocking means 10.

Thus, said housing 7 is composed of a cover 11 and an enantiomorphic bottom 12 comprising a series of housings in which the aforementioned elements take place. It is important to note that the thickness 7A, as well as the width 7B, of this housing 7, does not exceed the corresponding dimensions of the housing 2 of the cremone bolt or cremone bolt. This allows the use of identical tools when notching the edge of the opening.

Furthermore, according to the invention, this electrical locking device 6 can be embedded in the edge of an opening, either in the immediate extension and in a glued manner to the housing 2, or at any place, located on one side or on the other of the latter.

In the first case, the cover 11 and the bottom 12 of the housing 7 have, as shown in FIG. 1, a particular morphology at their part denoted 13 and cooperating with the housing 2, this characteristic having the function of ensuring their adaptation to one of the ends 2A, of the latter.

More precisely, said housing 2 is devoid, at one of its ends 2A, situated on the longitudinal axis of the operating rod or rods, of the wall forming the edge and connecting the front and rear covering plates of this housing 2. Thus, the part 13 of the cover 11 and of the bottom 12 constituting the housing 7, can be introduced, partially, for example, into the upper edge 14 of the housing 2, as shown in FIG. 1, and play a role of 'spacer coming to be inserted between the covering walls of the latter. This part 13 of the cover 11 and the bottom 12 is further provided with corresponding holes 15 with openings machined in said cover plates. These orifices 15 serve as passage for fixing members, such as screws, rivets or the like, to make the electrical locking device 6 secured to the casing 2 of the cremone bolt or cremone bolt.

The enantiomorphic nature of the cover 11 and of the bottom 12 makes it possible to ensure the reversibility of the electrical locking device 6, this both for right-left use on the opening, but also with respect to a median plane transverse to the housing 2 of the cremone bolt or bolt lock 81.

As regards the electrical control members 8 making it possible to actuate the motor means 9, these are composed of a control relay system 16 disposed in a housing 17 located in the upper part 17A of the housing 7. These members 8 electrical control also include a connection element 18 for connection with an external power supply connected, for example, to a control unit.

Note that to access this connection element 18, the bottom 12 and / or the cover 11 include a light allowing the introduction of a connection plug.

The electrical control members 8 intervene in the operation of the motor means 9 and, more particularly, of an electric motor driving the blocking means 10.

However, it can be envisaged to substitute an electromagnet for such an electric motor to drive the blocking means 10. The modifications which it would be advisable to make, under these conditions, to the housing 7 and, in general, to the all of the constituent elements of the electrical locking device 6 are within the reach of those skilled in the art. Therefore, it is obvious that such a substitution can be carried out without departing from the scope and the spirit of the present invention.

The locking means 10, actuated by the electric motor 9, consist, essentially, of a slide 19 moving in the housing 7, perpendicular to the longitudinal axis of the operating rods. Thus, the front end 20 of this slide 19 is able to cooperate, in the locking position, either with one of these operating rods 83, or with a connecting element 21, connected to the control mechanism 3. According to another operating mode, this front end 20 of the slider 19 can immobilize either an operating rod 83 or a connecting element 21, and, simultaneously, cooperate with the headrest 82 of the lever or lever-lock. Under these conditions, said headrest 82 plays the role of waste and comprises, for this purpose, an opening or a lumen in which the locking means 10 partially engage.

As regards the connecting element 21, this necessarily has a displacement in a direction substantially parallel to said operating rods 83, under the action of the control mechanism 3.

Figure 1 shows a fitting whose electrical locking device 6 and, in particular, the slider 19, cooperates with such a connecting element 21. In this specific case, the latter is connected to the bridge 5 giving two operating rods, s 'extending on either side of the housing 2, an identical displacement. However, in other cases, this connecting element 21 can be connected to any part of the control mechanism 3 and whose movement takes place according to the aforementioned conditions.

Thus, according to the configuration described above, the locking of the opening of a door, window or the like is obtained by moving the slide 19 in the direction of the headrest 82, so that its front end 20 is positioned at above the upper edge 22 of the connecting element 21, immobilizing the latter in its locked position. In contrast, the withdrawal of the slider 19 frees the control mechanism 3 while ensuring a displacement parallel to the operating rods to said connecting element 21.

The guide of the slide 19 is ensured by a set of ranges 23, 24, 25 arranged in the bottom 12 and in the cover 11 of the housing 7. However, it may turn out that the stress, exerted by a shark or a user not advised on a control member of the fitting, causes the slide 19 to flex under the effect of the thrust exerted by the connecting element 21. To remedy this drawback, said slide 19 is provided at its front end 20 with a shoe 26 whose upper edge 27 cooperates with a bearing 28 arranged in the bottom 12 and the cover 11, parallel to the movement of the slide 19. In the locked position, this shoe 26 is located in the extension of the connecting element 21.

According to another embodiment, as shown in FIG. 4, this shoe 26 is in the form of an element 70 in its own right, attached to the upper end 71 of a vertical branch 72 secured to the front end 20 of the slide 19. To this end, a cut is made in the upper edge 73 of this vertical branch 72, the lateral edges of which are able to engage in grooves 74 machined on either side of the shoe 26. Thus, just as before, the latter is able to place itself, in the locked position, above the connecting element 21, or even to act on an operating rod. This shoe 26 or, more precisely, the element 70 also cooperates, at its upper edge 75 with the bearing 28 arranged in the bottom 12 and the cover 11 and this, whatever the position of the slide 19.

In the context of direct cooperation between the locking means 10 and a rod for operating the cremone bolt or lever-lock, said operating rod 83 is provided with a light coming to be situated, in the locked position, in line with the slide 19. In this configuration, the front end 20 of the latter, whether or not devoid of a shoe 26, engages in this light arranged in the operating rod to immobilize the latter.

Furthermore, the shoe 26, whether or not defined by a separable element 70, can advantageously constitute a locking bolt which is able to penetrate, in the locked position, into the keeper formed by the opening in the headrest 82. This arrangement gives perfect reliability to the electrical locking device 6 since a forced action on the control mechanism 3 does not, in any case, deteriorate it.

It should also be noted that the shoe 26, in the form of the element 70, can be made of a more resistant material than that of the slide 19. This results in a reduction in the manufacturing cost of the latter and an increased longevity of the electrical locking device 6.

Preferably, the front end 20 of the slide 19 or the front face 76 of the shoe 26 (whatever its embodiment) are slightly chamfered around their outline or have a bias cut at the level of the lower part facilitating their engagement, either in a slot machined in the operating rod 83 and / or in the headrest 82, ie above the upper edge 22 of the connecting element 21.

The electric motor 9, making it possible to drive the slide 19, is introduced into a housing 29 arranged in the cover 11 and the bottom 12 of the housing 7. More particularly, this housing 29 ensures the rotation rotation of the electric motor 9. It has , for this purpose, a substantially cylindrical shape and comprises, on its internal wall and at one of its ends, an internal rim cooperating with a peripheral groove produced in the wall of the electric motor 9. During assembly, it is important that the engagement of this internal rim in the aforementioned peripheral groove takes place with a certain resistance. Of course, other means for blocking the rotation of the electric motor 9 can be envisaged.

The housing 29 also makes it possible to position the latter relative to the slider 19. Thus, according to the invention, said housing 29 is arranged so that the drive shaft 30 of the electric motor 9 is perpendicular to the movement of the slider 19 and is able to cooperate with the latter via appropriate drive means 31.

According to a first embodiment, the drive means 31 consist of a toothed wheel 32 mounted at the end of the drive shaft 30 and cooperating with a rack 33 machined in a slot 34 arranged in the slide 19.

Therefore, the drive of the electric motor 9 causes the rotation of the toothed wheel 32 and the translation of the slider 19 inside the housing 7. Preferably, the slider 19 comprises stop control means 36, 37 of the operation of the electric motor 9. Thus, these stop control means 36, 37 are constituted by wings 38, 39, extending, respectively, on either side of and from the slide 19. These wings 38, 39 constitute control fingers actuating, respectively, a stop switch at blocking 40 and a stop switch at opening 41. The designation of these switches 40, 41 is chosen by analogy to their function. Thus, the blocking stop switch 40 causes the electric motor 9 to stop when the slide 19 is in the advanced blocking position. Unlike, the opening stop switch 41 controls the stop of the operation of the electric motor 9 when said slide 19 is in the retracted position, having released the control mechanism 3 and, more particularly, the connecting element 21 or the rod. maneuver.

Advantageously, one 39 of the wings 38, 39 extending on either side of the slide 19 also serves as a manual control member of the latter. Indeed, for security reasons, it seems essential to be able to control the unlocking of the rods for operating the cremone bolt or bolt lock when the electric locking device 6 is put out of use or if its control is inaccessible.

To this end, the bottom 12 and / or the cover 11 is provided with a light 42 arranged in line with the wing 39 to ensure accessibility to the latter and to control the advance and, as a general rule, the decline of the slide 19.

Advantageously, this light 42 is of semicircular shape facilitating the transmission of the external action to the housing 7 on the slide 19.

The machining of the rack 33 of the slide 19 can prove to be a particularly delicate operation to carry out. To overcome this drawback, the drive means 31 can be formed, according to a second embodiment, by an eccentric secured to a disc driven in rotation by the drive shaft 30 of the electric motor 9.

Under these conditions, the slider 19 comprises, as shown in FIG. 3, on the one hand, a groove 43 in which the disc cited above is housed and moves. On the other hand, the slide 19 is provided with a cutout 44 machined in one of its lateral edges 45 and extending transversely to its longitudinal axis. Therefore, during the operation of the electric motor 9, the eccentric moves inside the cutout 44 while causing the slide 19 to move back or forward.

However, this driving of the slide 19 by means of an eccentric can have a drawback, in particular in the context of a manual release command. Indeed, such a manual control, obtained by acting on the wing 39 may prove to be practically impossible when the eccentric is located substantially in the longitudinal axis of the slide 19, therefore in alignment with the drive shaft. 30 of the electric motor 9 and in the extension of the force applied to said wing 39.

To remedy the aforementioned drawback, the drive means 31 consist, according to a third embodiment shown in FIG. 4, on the one hand, of a disc 50 secured to the drive shaft 30 and bearing an eccentric 51. The latter is engaged in a cutout 52 machined in the slide 19 and having a morphology identical to the cutout 44 described above. On the other hand, these drive means 31 comprise a manual control pusher 46 composed of a wing 47 extending parallel and above the slide 19 and a control lever 48 secured to one of the longitudinal edges 77 of said wing 47 and extending below the slide 19.

More specifically, the wing 47 of this control pusher 46 is provided with a rack 49 meshing on a ring gear 78 surmounting the disc 50. Furthermore, the control lever 48 is inserted in a recess 79 produced in the lateral edge 80 of the slide 19 and is in the same plane, perpendicular to the housing 7, as the wing 39 constituting the stop control means 37. This arrangement ensures accessibility to said control lever 48 by means of light 42.

For the proper functioning of the drive means 31, in accordance with this third embodiment, it is important to ensure a certain clearance either of the eccentric 51 in the cutout 52, or of the control lever 48 in the recess 79.

The advantage of such a manual control pusher 46 is that it is possible to transmit a tangential force on the ring gear 78, regardless of the position of the eccentric 51 in the cutout 52 with respect to to the longitudinal axis of the slide 19.

In Figures 5 and 6 is shown a guide member 54 attached to the end 2A of the housing 2 of the lever or lever-lock, where the electrical locking device is located 6. More precisely, this guide element 54 allows 'ensure the functions which are usually fulfilled by the edge of the case which does not exist in the context of the lever or lever-bolt shown in Figure 1.

Thus, this guide element 54 makes it possible to maintain and guide the operating rod 83 and, moreover, the connection between the housing 2 and the headrest 82. Advantageously, it also makes it possible to guide the connecting element 21 during its movements parallel to the longitudinal axis of the operating rod or rods.

According to a preferred embodiment, this guide element 54 consists of a body 55 of parallelepiped shape and of width 56 substantially equal to the distance respected by the front and rear cover plates forming the housing 2. This body 55 is provided, on its lateral sides 57, with a tongue 58 cooperating with an opening made in said cover plates to ensure, after assembly of the latter, the connection between the guide element 54 and the housing 2.

In addition, two flanks 59, located on these same lateral sides 57 of the body 55, are projecting with respect to the front face 60 of the latter. Between these two flanks 59 are caused to move, simultaneously, an operating rod 83 and the connecting element 21.

This front face 60 of the body 55 also has a central boss 61 which engages in the slots machined respectively in said connecting element 21 and in the operating rod 83. A pin 62 disposed on this central boss 61 makes it possible to position box 2 of the cremone bolt or lock-bolt on the headrest 82. In addition, a threaded orifice 63, placed under the central boss 61, authorizes the engagement of a screw ensuring their connection.

It is obvious that such a guide element 54 only has its usefulness in the context of a fitting, the electrical locking device 6 of which is attached to the casing 2 of the cremone bolt or cremone bolt and / or whose means of blocking 10 cooperate with a connecting element 21 and not with an operating rod.

The advantages obtained thanks to this fitting, in accordance with the invention, consist in that the notching which it is necessary to make in the amount of an opening to embed the casing of the cremone bolt or cremone bolt and the device for electric locking has dimensions, in particular, in depth and in width of the standard type and usually applying in the context of conventional bolts and bolts. Furthermore, the constituent elements of the latter, and in particular, their control mechanism and their housing, differ only in minute details near those involved in the fitting of the present invention.
