Description

The invention relates to a locking fitting for a door, a window or the like comprising a control mechanism for pushing at least in the unlocked position at least one locking member provided to cooperate with a keeper and which are associated with adjustment means in position. , this control mechanism further comprising an anti-false-maneuver device provided with a movable control probe, against the action of elastic return means, between an active locking position and an unlocking position, this anti-false device operation further comprising means for retaining at least one locking member in the unlocked position when the control probe is in the active blocking position.

The present invention will find its application in the field of lock fittings for door, window or the like, fittings provided with an anti-false-maneuver avoiding, especially when said door, window or the like is in an open position, pushing the lock fitting into a locked position.

There already exist multiple lock fittings as described above. Such fittings are described, for example, in the following documents: EP-0 693 604, EP-0 881 347, EP-0 246 172, EP-0 942 132.

Particularly, in all these documents of the state of the art, there are described locking fittings comprising a control mechanism that can adopt different embodiments, but which systematically contributes at least to the unlocking control, under the impulse of a maneuvering member, such as a button or a handle or a key element. More specifically, through this control mechanism is operated at least on a locking member, in the form of a hook bolt, a roller or the like, to push it into an unlocked position in which it is likely to to release a strike allowing the opening of the carpentry. Note that the return to the locking position of such a bolt hook, roller or other locking member, can be obtained through the same control mechanism and by action on the operating member associated with it, or still under the impulse of elastic return means.

To prevent the locking member (s) from being pushed into their locking position even before the door or window is closed again, these locking fittings described in the various documents cited above systematically include an anti-false-lock device. maneuver. The latter comprises, in the usual manner, a movable control probe, against the action of elastic return means, between an active locking position and an unlocking position. The operating principle being the following: after unlocking control of the locking fitting and opening of the door or window, the elastic return means push the control probe in its active locking position. At this time, there is cooperation with the control mechanism so as to prevent that through the latter or the locking members can be pushed from their unlocked position in their locking position. Conversely, when closing the door or window, the control probe is thus positioned to be actuated through the meeting between the opening of the door or window, equipped with the locking fitting, with, for example, the frame sleeping. Through this actuation the control probe is pushed from its active locking position in the unlocking position, against the action of the elastic return means. In this unlocking position the control mechanism, released in its movements, allows the locking control, and therefore the displacement of the locking members.

Position adjustment means are often associated with the locking members of these fittings. For example, such adjustment means allow, for example, to intervene on a hook bolt to adjust its protruding protruding length of the front pillar of a sliding leaf, this depending on the implementation on the frame sleep of the striker with which is brought to cooperate this hook bolt. For example, this implementation of the lock on the joinery may depend on the configuration of the profiles defining, as the case, the frame or the frame of an opening of the door or window.

These adjustment means associated with a locking member are also intended to ensure the cooperation of the latter with the striker in which it is intended to be housed according to the rebate set between opening and frame. Moreover, this rebate game can evolve over time, whether by sagging, deformation or otherwise, again requiring, to change the positioning of the locking members relative to their respective strikes.

It goes without saying that if it is necessary to adjust or adjust the positioning of the locking members according to the parameters mentioned above and in particular according to the different profiles of carpentry, it is the same with the control probe the anti-false-maneuver device.

Thus, provided that the control probe is too recessed in rabbet of a sliding leaf can not be pushed properly in its unlocking position through its cooperation with the frame, thus preventing the locking operation. Conversely, a control probe actuated too early leads to release the control mechanism of the lock fitting before the locking members are positioned to the right of their strikes and mishandling is then possible. This is the reason why it is usual for the control probe itself to be adjustable in position thanks to adjustment means which are directly associated with it.

Finally, if the solutions according to the state of the art satisfactorily satisfy the constraints of the adjustment in position whether of a locking member or a control probe of an anti-tamper device this, depending on the constraints of implantation of a locking fitting on a door or window joinery, it is found that it is up to the operator to intervene, at the same time, on the means of adjusting an organ and those associated with a control probe to achieve optimum operation of this lock fitting. It is within the framework of a first inventive step that it has been shown that an adjustment of the positioning of a locking member, such as a hook bolt or the like, according to a given type of Carpentry profile necessarily leads to an equivalent amplitude adjustment of the control probe. This is all the more true that it is common to make interact such a control probe with a strike with which is brought to cooperate such a locking member.

Consequently, it is within the framework of a real inventive step that it has been imagined that the control probe is made integral in displacement of a locking member under the influence of common position adjustment means, in particular, when the control probe is in its active blocking position.

The present invention should be understood in that these position adjustment means are distinct from the means that defines, in particular, the control mechanism, to push the locking member between its locked and unlocked position or vice versa.

The advantages resulting from the present invention consist in that the adjustment in position of the locking members and a control probe of an anti-false-maneuvering device according to the constraints of implantation of a locking fitting on a carpentry, is carried out with greater ease by the operator-fitter. Above all, any subsequent adjustment of this position setting is achieved with increased security. In particular, whether it is a user or an experienced operator, it can no longer omit to adjust at the same time the position of the control probe when it intervenes on the correct positioning of the locking members. To this end, the invention relates to a lock fitting for a door, window or the like comprising a control mechanism for pushing at least in the unlocked position at least one locking member provided to cooperate with a strike and which are associated with adjustment means in position, this control mechanism further comprising an anti-false-maneuver device provided with a movable control probe, against the action of elastic return means, between an active locking position and an unlocking position, this anti-false-maneuvering device further comprising means for retaining at least one locking member in unlocked position when the control probe is in the active blocking position, characterized in that said control probe is made integral in displacement. a locking member under the influence of the adjustment means in position of the latter, in particular when the control probe is in active blocking position. Other advantages arising from the present invention will become apparent from the following description relating to an example of the embodiment given by way of indication and not limitation.

The understanding of this description will be facilitated with reference to the attached drawing in which: - Figure 1 is a schematic representation of a sliding door type of carpentry equipped with a lock fitting according to the invention, - Figure 2 is a schematic and partial representation of a lock fitting according to the invention in unlocked position, - Figure 3 is an illustration similar to Figure 1 illustrating the lock fitting unlocked, the anti-false-maneuvering device being activated - Figure 4 is a view similar to Figures 2 and 3 illustrating the lock fitting in the locking position.

As shown in the figures of the accompanying drawing, the present invention relates to the field of door lock fittings, window or the like.

More particularly, there is illustrated in these figures a lock fitting 1 according to the invention for door 2 or sliding window.

Thus, the latter 2 comprises an opening 3 slidably mounted on a frame 4. The opening 3 is equipped with a locking fitting 1, according to the invention, in rebate of its front post 5, intended to come close again. on the corresponding amount 6 of the sleeping frame 4.

More particularly, the locking fitting 1 comprises a control mechanism 7 through which at least one locking member 8, here represented in the form of a hook bolt, can be pushed back at least in the unlocked position. Note, in this connection, that by means of such a control mechanism 7 or these locking members 8 can also be returned to the locking position 10 as illustrated particularly in Figure 4, knowing that this lock control can also be obtained under the impulse of elastic return means acting, as the case may be, directly on this or these locking members 8 or indirectly through said control mechanism 7.

Of course, the action even on the control mechanism 7, in particular for the unlocking control, can be obtained by means of any operating member 11 illustrated in the form of a handle in FIG. 1, knowing that this organ maneuver can still be in the form of a key cylinder or an electric motor.

As illustrated in the figures, the locking member 8, here in the form of a hook bolt, is provided to cooperate, in the locking position 10, with a keeper 12, an exemplary embodiment of which is particularly visible in FIGS. at 4.

This locking fitting 1, according to the invention, further comprises an anti-false-maneuvering device 13 whose essential function is to maintain the locking member (s) 8 in their unlocked position 9 when the door or window 2 is open. More particularly, this anti-false-maneuvering device 13 prevents this or these locking members 8 can be pushed into their locking position 10, as the opening 3 is not closed on its frame 4, without this or these locking members 8, rather than engage in their respective strikes, would hit them during the closing command of 1'ouvrant 3.

This anti-false-maneuvering device 13 is provided with a movable control probe 14, against the action of elastic return means 15, between an active locking position 16, which is shown in FIG. 2 and an unlocking position 17 visible in Figures 3 and 4.

This anti-false-maneuvering device 13 also comprises means 18 for retaining the locking member (s) 8 in unlocked position 9, when the control probe 14 is in its active locking position 16. Note that these means 18 are further defined to, conversely, releasing the locking member (s) 8 when the control probe 14 is pushed towards its unlocking position 17.

In the usual way, this control probe 14 is mounted on the locking fitting 1 so as to protrude from the front face 19 of the latter. According to the opening direction of the opening 3 relative to the fixed frame 4, this control probe 14 can be movable perpendicularly or parallel to this front face 19 of the locking fitting 1.

This front face 19 can be defined substantially by a headrest at the rear of which are housed the various components of this fitting.

In the illustrated embodiment, the locking fitting 1 applying to a sliding leaf 3, this control probe 14 is movable perpendicularly to this front face 19 so as to be more or less salient in front of the latter .

Thus, when closing the opening 3, in cooperation with, as the case, the fixed frame 4 or, as shown, a keeper 12 mounted on the latter, the control probe 14 is pushed towards this front face 19 More particularly, in the embodiment as visible, this control probe 14 is pushed inside a housing 20 against the action of elastic return means 15 such as a spring, housed by this housing 20 .

Of course, in the case of a pivoting opening 3, this control probe 14 can be rotatably mounted, such as a rocking lever, on the front face 19 of the locking fitting 1. In this case, internally to the housing 20, this tilting control sensor 14 may be in cooperation with a lever on which said elastic return means act.

As for the retaining means 18, they comprise, inside the housing 20, a locking pin 21 depending on said control sensor 14 and which, in the active locking position 16 of the control sensor 14, constitutes an obstacle to the movement of the locking members 8 holding the latter or these in the unlocked position 9. In contrast, in the unlocking position 17 of the control probe 14, this locking pin 21 is erased to allow the locking member (s) 8 to be displaced. from their unlocked position 9 in their locking position 10 and vice versa.

It is usual for a locking member 8, such as a hook bolt, to be associated with means 22 for adjusting the position. Such means 22, also known to those skilled in the art and not visible in detail in the figures of the accompanying drawings, make it possible to adjust the positioning of this locking member 8 to ensure its cooperation with the latch 12 corresponding on the sleeping frame 4, this according to constraints related to the implementation of the lock fitting 1 on a joinery.

Thus, such an adjustment of a locking member 8 may be necessary depending on the rebate clearance between the opening 3 and the frame 4, or even in case of modification of the rebate game over time.

In the case more particularly of the embodiment illustrated in the figures of the attached drawing, such a setting of a locking member 8 in the form of a hook bolt may be necessary to adjust the projecting length of the hook bolt relative to the front face 19 of the locking fitting 1, this depending on the dimensions and / or configuration of the profile defining, for example, the front post 5 of the opening 3 accommodating the locking fitting 1 and / or that corresponding to the amount before 6 of the frame 4 accommodating the keeper 12 with which is brought to cooperate this hook bolt 8.

It goes without saying that if it is necessary to adjust the protruding length of a hook bolt front face 19 of the locking fitting 1, this due to the latter's installation constraints on the joinery, it is necessarily necessary to even of the control probe 14.

Once again, it should be observed that if the invention is described and illustrated in the context of its application to a sliding leaf leading to an adjustment of the pieces in a direction perpendicular to the plane of the front face 19 of the locking fitting 1, this invention is entirely transferable to a carpentry with pivoting opening where this adjustment in position where is substantially transversely and parallel to this front face 1 of the locking fitting 1.

Thus, according to the invention, the control probe 14 is secured in displacement of a locking member 8, displacement conferred under the influence of the adjustment means in position 22. In particular, this securing in displacement occurs when the control probe 14 is in the active blocking position 16.

In the exemplary embodiment illustrated in the accompanying drawings, the locking pin 21, in this active locking position 16 of the control sensor 14, bears, at least on the end portion 23, inside the housing 20, hook bolt 8.

Also, it is understood that by adjusting, through the means 22, the projecting length of the hook bolt 8 relative to the front face 19 of the locking fitting 1, this end portion 23, internal to the housing 20, of this hook bolt 8 necessarily moves. Also, during this adjustment of the hook bolt 8 moves, simultaneously, the control probe 14 secured to the locking pin 21.

As already indicated above, the adjustment means 22 may adopt different embodiments. Thus, in the case of a locking member 8 in the form of a hook bolt, it can extend through a holding housing 24 on which is defined able to act the control mechanism 7. This housing 24 comprises, for example, a clamping screw immobilizing in the latter said hook bolt 8. This holding case 24 may further be provided with a set screw acting on a rack 25 extending along the bolt. crochet 8, etc.

The advantages deriving from the present invention consist in that by adjusting the positioning of a locking member 8 according to the constraints of implantation of a locking fitting on a joinery, the result is, at the same time, the adjustment of the locking device. anti-false-maneuver 13 with respect to these same implantation constraints.

Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations of these various elements can be made. without departing from the framework and spirit of the invention.
