Description

The invention relates to a locking fitting for a sliding leaf comprising a control mechanism for pushing at least in the unlocked position at least one locking member provided to cooperate with a striker and which are associated with means for adjusting the position. control further comprising an anti-false-maneuvering 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 comprising still means for retaining at least one locking member in the unlocked position when the control probe is in the active locking position.

The present invention will find its application in the field of locking fittings for a door, window or the like, fittings provided with an anti-false-maneuver preventing device, 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 an operating member, such as a button or a handle or a key element. More precisely, through this control mechanism, at least one locking member acts in the form of a hook bolt, a roller or the like, for push the latter into an unlocked position in which it is likely to disengage a strike allowing the opening of the joinery.

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 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 of the anti-false-maneuvering 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 respond satisfactorily to the constraints of the adjustment in position whether of a locking member or a control probe of an anti-false-maneuvering 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 adjustment means of a control member. locking and those associated with a control probe to achieve optimal operation of this lock fitting.

It has been demonstrated that adjustment of the positioning of a locking member, such as a hook bolt or the like according to a given type of joinery profile necessarily leads to an equivalent amplitude adjustment of the probe. control. 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 has been imagined that the control probe is made integral in displacement of a locking member under the influence of common position adjustment means, this in particular when the control probe is in its active blocking position. . Such a locking fitting is described in the document US-8,931,812 .

The adjustment means in position are distinct from the means that defines, in particular, the control mechanism, to push the locking member between its locked position and unlocking or vice versa.

The advantages 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 lock fitting on a carpentry, s performed with greater ease by the operator-fitter. Especially, any further adjustment of this position setting is achieved with a safety increased. 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.

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 the figure 4 , knowing that this locking control can still be obtained under the influence 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 the figure 1 , knowing that this body of 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 striker 12, an exemplary embodiment of which is particularly visible in the Figures 2 to 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 what or these locking members 8, rather than engage in their respective strikes, would hit the latter during the closing order of the opening 3.

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

This anti-false-maneuvering device 13 also comprises means 18 for retaining the locking member (s) 8 in the 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. Depending on the opening direction of the opening 3 with respect to the fixed frame 4, this control probe 14 may be movable perpendicularly or parallel to this front face 19 of the lock 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 the 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 make it possible to adjust the positioning of this locking member 8 to ensure its cooperation with the corresponding striker 12 on the fixed frame 4, this as a function of constraints related to the implantation of the locking 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.

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.

According to the invention, 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, of the 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.

Another feature is that the hook bolt 8 adopts the shape of an "L" piece and comprises, on the one hand, a first branch 80 constituting an attachment member designed to cooperate with the striker 12 and, on the other hand, a second leg 81, extending from the first leg 80 perpendicularly, and having at one end, opposite to that from which the first leg 80 extends, said end portion 23.

Another characteristic consists in that the locking pin 21 comprises, on the one hand, a bearing surface 210 against which the end portion 23 abuts (more particularly a free end 230 that this end portion comprises 23) of the hook bolt 8, in particular in the active locking position 16 and / or during the adjustment in position of the hook bolt 8 and / or the anti-false-maneuvering device 13. On the other hand, this finger of blocking 21 comprises a bearing flange 211 against which abuts the end portion 23 (more particularly a stopper 231 that includes this end portion 23) of the hook bolt 8, in particular in the active blocking position 16. This bearing surface 210 and this bearing flange 211 are defined by a recess that includes the locking pin 21 and / or s perpendicularly extend one 210 relative to the other 211 and / or the extension 210 of the other 211.

In fact, this locking pin 21 extends laterally with respect to a plunger 140, which comprises the control sensor 14, which protrudes from the front face 19, which can take the form of a rod or the like, and which is designed to cooperate with the keeper 12 or with the frame 4.

In addition, this locking pin 21 has a free end 212, opposite to an end from which the plunger 140 extends, and which comprises said bearing surface 210 and the bearing flange 211.

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, which comprises the locking fitting 1, which is movable to the inside of the housing 20, and through which this hook bolt 8 extends. It is, more particularly, on this holding case 24 that the control mechanism 7 is defined able to act, more particularly for controlling moving the hook bolt 8 from the locking position 10 to the unlocked position 9, or even from the unlocked position 9 to the locking position 10.

In fact, this holding box 24 is movable in a direction parallel to the front face 19 of the locking fitting 1 and / or between the unlocked position 9 and the locking position 10 of the hook bolt 8.

Another feature is that the holding case 24 is positioned between the retaining means 18 and the front face 19 of the lock fitting 1.

As regards the adjustment means in position 22 of the locking member 8, these are, in fact, made of by means for adjusting the position of the hook bolt 8 relative to the holding case 24.

Such adjustment means in position 22 then comprise, on the one hand, a rack 25 extending along the hook bolt 8 (more particularly than the second branch 81 of the "L" part of this bolt hook 8) and, on the other hand, a set screw 26, which is provided with the holding case 24, and which acts on the rack 25.

Yet another characteristic consists in that the holding box 24 comprises immobilization means for immobilizing the hook bolt 8 inside this holding box 24. Such immobilizing means are, more particularly, actuated after the implementation of the adjustment means in position 22. According to a preferred embodiment, these immobilization means are constituted by a clamping screw immobilizing said hook bolt 8 in the holding housing 24.

Another characteristic of the invention consists in that the control probe 14 comprises adjustment means for adjusting its protruding length with respect to the front face 19 of the locking fitting 1, more particularly as a function of the distance between, on the one hand, this front face 19 and, on the other hand, the keeper 12 and / or the frame 4.

In fact, these adjustment means comprise, on the one hand, complementary probing means (not shown) and, on the other hand, receiving means 142, which are configured to receive these complementary probing means, and that comprises an end portion 141 of the control probe 14, more particularly of the plunger 140 of this control probe 14.

With regard to these complementary probing means, these are interchangeable and of different lengths, in order to adjust the protruding length of the control probe 14.

In fact, these complementary probing means may take the form of a stud, a ball, a rod or the like.

Regarding the receiving means 142, they may take the form of a housing, more particularly whose characteristics (including geometry and / or dimensions) are configured to receive and maintain the complementary probing means.

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.
