Description

The invention relates to a locking fitting for an opening slider comprising a housing extending perpendicularly at the back of a mounting plate with an opening access to an actuator for the control in displacement, between a locking position and a position unlocked, at least one slider mounted axially movable in said housing and provided able to act at least on a bolt carrier.

The present invention relates more particularly to the field of locking fittings for sliding leaf.

We already know, in particular from the documents FR-2,808,832 and EP-0,044,264 lock fittings for sliding leaf as described above. So, such fittings include a housing adapted to register in the thickness of the front pillar of a sliding leaf, the back of an inner fixing plate knowing that this fitting can still be provided with an outer plate presenting, for example, a key element for the control of locking and unlocking.

Anyway, the case of such a fitting of locking for sliding leaf is constituted, substantially by said inner fixing plate and two parallel walls extending perpendicular to the back of this plate, knowing that these walls are provided, substantially up to their free end singing, a return delimiting, thus, with said internal fixing plate, a guide channel of a slide. In short, this one fits between the aforementioned returns and the rear face of said plate internal fixation.

It is provided with a maneuvering device to act on this slider. According to a particular embodiment, this internal fixing plate has an opening longitudinal allowing direct access to the slider which is then provided with a bowl handle.

This slide comes act, as the case, directly or at through a vacuum stroke, on a bolt carrier which comprises means for adjusting in position a hook bolt or similar. In particular, through these adjustment means it is, for example, possible to adjust the protruding length of this hook bolt relative to the singing of the amount before the sliding door.

It is very common to equip this lock fitting an anti-false-maneuver and / or burglar-proof device. The first is to prevent the hook bolt can be mistakenly returned from its locked position locking position, as long as the sliding leaf does not have was closed on the sleeping frame. If that were to happen, he It is obvious that when closing the door or window, the hook bolt, previously pushed back into position interlock would hit the strike arranged in correspondence on the sleeping frame, instead of engaging normally.

The burglar alarm device is intended to prevent acting directly on a locking member and the hook bolt, it can be pushed back, from its locking position, in its unlocked position. This would allow a bittersweet to penetrate, very easily, in a dwelling.

In some designs and with some adjustments the action on the slide can be reflected on one or more rods of maneuver extending above or below the housing of the lock fitting, to control, simultaneously, several organs of locking, for example several hook bolts in view to ensure a multipoint type lock.

In particular, it can be seen that the bolt carrier on which comes to act the slide of such a fitting of lock for sliding leaf, comes in form a molded housing that is either independent and united moving in different ways of the slide, is done integral part of the latter, also obtained by a process molding.

The first solution of an independent case is the most often adopted when the slide is engaged on the bolt carrier beyond a vacuum run, for example, for the command for unblocking an anti-intrusion device or the like.

Anyway, such a molded bolt holder case turns out a significant manufacturing cost. Moreover, the problem of immobilization, in relation to this bolt carrier, of locking bolt, which must still be adjustable in order to adjust its position according to the location of the waste with which it is intended to cooperate.

In this connection, it has been described in EP-A-1,258,582, a lock fitting for a sliding leaf the recess in the bolt carrier, intended to receive the tail of this locking bolt, has characteristics specific to ensure this immobilization function.

In particular, in this recess is arranged a ramp with which is able to cooperate a toothing that includes the body of the hook bolt and which promotes the attachment of this last in the bolt holder to withstand any possible shocks that may, on different occasions, undergo such a fitting sliding door.

In the end, the present invention makes it possible to simplify the design of such a fitting for sliding leaf, in view a lower manufacturing cost, without its characteristics mechanics are altered.

In particular, the bolt carrier, resulting, preferentially, from simple cutting and stamping operations of the slider, is designed in such a way as to guarantee the immobility of the bolt hook through a perfect isostatic support.

The invention also aims to provide a solution to the problem posed, in general, these iron fittings because of their complexity and the means of various manufacturing, such as stamping, molding, machining, etc. that should be implemented for their design.

Finally, it aims to review the latter for respond to congestion problems.

For this purpose, the invention relates to a lock fitting for sliding leaf having a housing extending perpendicular to the back of a mounting plate provided an access opening to a control device for the control moving, between a locking position and a unlocking position, of at least one mounted slide mobile axially in said housing and provided able to act at less on a bolt carrier, characterized by the fact that said bolt carrier is defined at one end of the slide by a median band that delimit cutting lines in relation to lateral bands, the latter and / or said median band being bent at their ends to extend into parallel offset planes and define a transversal light of passage of the tail of a locking bolt, said strips side, the middle band and at least one of the ends bent of one and / or the other of these constituent strips at least three isostatic points of support.

According to the invention, a fourth isostatic point is constituted, as the case may be, by the other end bent of this or these bands, median or lateral, or by means of clamping.

Advantageously, these clamping means consist of by a screw through a threaded opening in the band median or one of the lateral bands, so as to cooperate with a locking bolt tail engaged in the transverse light of said bolt carrier.

According to another feature of the invention, the bolt holder extends staggered towards the inside of the housing by relative to the general plan of the slider.

In addition according to the invention, the slider results from cutting and stamping a metal plate.

Furthermore, according to the invention, the housing comprises walls side parallels extending perpendicular to the back of said fixing plate, these walls comprising a light oblong for the passage of the tail of a locking bolt in such a way as to enable the latter to cooperate with the bolt holder.

According to another feature of the invention, the slide is mounted substantially at the end edge and between these walls parallel sides of the housing, so as to close, at least partially, the latter at the rear and delimit, with the fixation plate, a volume of reception of organs of command and / or security.

According to another particularity of the invention, the organ of maneuver is mounted mobile transversely to the housing, either perpendicular to the fixing plate, while means are designed apt to transform this displacement transverse of the actuator in a displacement longitudinal axis of the slide.

In a particularly advantageous manner, the slider can be extended to one and / or the other of its ends by means defined junctions able to cooperate with joining means complementary associated with maneuvering rods.

The advantages that flow from the present invention consist, essentially, in that the slide can be designed by simple cutting and stamping of a metal plate, while incorporating a bolt holder meeting the criteria of holding required for such a lock fitting for sliding door.

In particular, through the very design of this bolt carrier, it can be positioned inside the housing extending under the internal fixing plate. Also, this housing, in particular its parallel side walls are in able to ensure perfect guidance of the bolt carrier and directly oppose constraints that would be applied on the latter through the locking bolt.

The maintenance of this locking bolt is further improved by the opening in one of the parallel side walls that comes cross its tail to cooperate with said bolt carrier.

As shown in the various figures of the attached drawings, the present invention relates to a fitting of lock 1 more particularly applicable to openings sliding.

Such a fitting 1 comprises a housing 2 consisting of two parallel walls 3, 4 extending substantially perpendicular to the back of a fixing plate 5. This has an opening 6 allowing access to a actuating member 7 for the control movement, between a lock position and unlocked position, from to minus one slider 8.

In a particular way to the present invention, this slider 8 resulting, preferably, from a cut metal dish and stamped is slidably mounted substantially at the end edge free 9, 10 and between the parallel walls 3, 4 of the housing 2. Also, it comes to close, at least partially, the latter in rear part and delimits, with the fixing plate, a receiving volume of control members and / or safety.

Especially, at this end edge 9, 10 and the inner side to this housing 2, these parallel walls 3, 4 have grooves 11 for receiving the borders 12, 13 of the slide 8. Note that these borders 12, 13 of the slider 8, so that they can slide in the grooves 11, can be shaped by stamping.

It should be noted that, advantageously, this slider 8 is transversely arched, which allows to improve the rigidity. This arch extends backwards, so to the outside of the housing 2 and allows to increase so advantageous the volume of the latter.

According to another particularity of the invention, at one end 14 of this slider 8 is designed, by stamping-cutting, a bolt carrier 15.

Thus, symmetrically and parallel to the longitudinal axis 16 of the slider 8 are made by a stamping tool adapted, cutting lines 17, 18. These define a median band 19 and sidebands 20, 21, the first and / or these are counter-bent at their ends 25, so this middle band 19 and the sidebands 20, 21 extend in parallel offset planes. This allows define a transverse light 22 for passage of the tail 23 a bolt 24, in this case a hook bolt.

It will be observed that the lateral bands 20, 21 and the median band 19 define two isostatic support planes at this tail 23 of the hook bolt 24. While a third isostatic point is constituted by at least one of the ends bent of this median strip 19. A needle screw 26 through a threaded aperture 27 in the middle strip 19 can create, in this case, the fourth isostatic point. It is to note that the tail 23 of the hook bolt 24 can be notched on its side edges, notches with which is able to cooperate with this needle screw 26, so as to ensure axial immobilization of this hook bolt 24.

However, the fourth isostatic point can still be defined by the other end bent of the middle band 19 to which is then adjusted the tail 23 of the bolt 24, the screw needle ensuring only the immobilization in translation of this latest. In particular, in such a situation, the 23 of the bolt 24 can be provided with a serrated light on its longitudinal edges to improve this immobilization in translation by said needle screw 26.

Advantageously, again, the bolt carrier 15 extends from staggered way inside the housing 2 relative to the general plane of the slider 8, while the parallel walls 3, 4 of this housing 2 comprise, in the right of this bolt holder 15, an oblong light 28 intended, again, to the passage of the 23 of the hook bolt 24. In sum, such a light 28 ensures a perfect maintenance of the whole in the volume of the housing 2 and participates in the good holding or maintaining the bolt to hook 24 in the bolt carrier 15.

It will be observed that the shifting towards the inside of the housing 2 the bolt carrier 15 leads to bring it to the plate of 5, which results in a better recovery of printed forces to the fitting 1 through the bolt 24.

In this same objective, the difference between the plane of the bolt holder 15 and that of the slider 8 results from a double folding 8A in "S" printed on the latter, with a first elbow 8B extending between the grooves 11 and to the end edge 9, 10 of the parallel walls 3, 4. This double folding 8A in "S" ensures, finally, perfect guidance and lateral support of the slider 8.

des doigts de commande pour assurer le déplacement de ce coulisseau 8, entre sa position de verrouillage et sa position déverrouillée ;

et/ou des doigts de blocage prévus aptes, en coopération avec des plans butés 32, 33, 34, à concevoir, selon le cas, un dispositif d'anti-effraction 35 et/ou un dispositif d'anti-fausse manoeuvre 36.

In a very particular way according to the invention, in the slider 8 are cut and folded more or less inside the housing 2, one or more tongues 29, 30, 31 may define, as the case may be:

control fingers for moving said slider 8 between its locked position and its unlocked position;

and / or locking fingers provided capable, in cooperation with abutment planes 32, 33, 34, to design, as the case may be, an anti-burglar device 35 and / or an anti-false-operation device 36.

According to another particularity of the invention, the organ of maneuver 7 is designed to move transversely across the housing 2 in the opening 6, perpendicular to the plane of the slider 8, while means 37 are provided for transforming this displacement of said operating member 7 into a longitudinal axial displacement of this slider 8.

Thus, the actuating member 7 is superimposed on the slide 8, guiding means 38 ensuring its maintenance and guidance transversely inside the housing 2. These means 38 are defined, on the one hand, at the level of the parallel sidewalls 3, 4 of this housing 2, by transverse oblong openings 39, 40 in which is able to come to engage, in particular in an elastic manner, a guide pin 41 that includes each of the side walls 42 of this operating member 7.

Moreover, this one is designed to interact with the control fingers in the form of inclined planes 45, 46 that define one or more tabs 29, 30 cut in the slide 8.

More exactly, the operating member 7 has on its side oriented towards this slider 8, one or more edges 43, 44 taking advantage of these inclined planes 45, 46 defined by the said tongues 29, 30. Thus, under the effect of a pressure exerted on this operating member 7 and the action of said ridges 43, 44 on these inclined planes 45, 46, the result is a displacement longitudinal direction of the slider 8. Obviously the direction of the displacement communicated to the latter depends on the orientation of the plans 45, 46. Preferably, these are oriented so that under the effect of pressure exerted on the actuator 7 results in the unlocking of the fitting 1.

The reverse movement advantageously results from the action of elastic return means not shown in the drawings. Of such elastic return means can act directly on the slider 8 to, for example, be put under stress during the unlock command. Also, coming to relax the action on the operating member 7, these return means elastics push the slide 8 in the position of locked. The interaction between the inclined planes 45, 46 and the edges 43, 44 has the effect of reducing, simultaneously the operating member 7 in its rest position.

Advantageously, at least one of these same tongues 29, 30 corresponding to the inclined planes 45, 46 defines, at through its end edge 49, 50, a locking finger coming to cooperate with a plane stop 32, 33 to oppose, from a locking position to a possible attempt to unlock the fitting 1 by direct action on the hook bolt 24 and constitute, thus, the device burglarproof 35.

It is illustrated by the arrow referenced 51 in FIG. such action that would be passed directly on the slider 8. As can be seen, the end edge 49, 50 of the tabs 29, 30 then meets these stop plans 32, 33. These are defined in the design according to Figure 6, in particular by means of recesses 52 at the free end of the edges of retained 47, 48 extending under the operating member 7. This last being here in his resting position he can not to extract more from the housing 2 and is thus opposed to displacement. It will be noted, in particular, that these retaining edges 47, 48 are of opposite orientation to tongues 29, 30.

In fact, such retaining ridges 47, 48 can, possibly, constitute lifting wedges which, by coming extend under an inclined plane 45, 46 when ordering unlocking, can intervene, in the manner of the edges 43, 44, on this inclined plane 45, 46 to push the slide 8 in locking position under the effect of the restoring force of elastic means acting on the operating member 7. All as before, such elastic return means are set under stress by exerting a pressure on this organ of maneuver 7.

As for the anti-false maneuver device 36 that we see shown in Figures 1, 4 and 5, its function is to keep the slide 8 and, therefore, the hook bolt 24 in its unlocked position after opening the door or window.

As already mentioned above, this anti-false device maneuver 36 is constituted, on the one hand, by a tongue 31 cut axially in the slider 8 and pushed back to inside the housing 2 so that this tongue 31 define a blocking finger. More specifically, the end free 53 of this tongue 31 is thus oriented and offset by relative to the plane of the slider 8 so as to form a redan in the direction of displacement of the lock, represented by the arrow 54.

On the other hand, this anti-false maneuver device 36 consists of in a stop plane 34 disposed inside the housing 2 of such way that in the unlocked position the tongue 31, plus precisely, its free end 53 comes to be in front of of this plane stop 34 and, forming redan, opposes a reverse movement of the slider 8 towards the locking.

Finally, this anti-false maneuver device 36 is completed by a deblocking control member 55 provided capable of repelling elastically the tongue 31 in the plane of the slide 8 and, thus, to ensure the erasure of its free end 53, forming redan, in front of the stopper 34. The elastic return means of the slide 8 ensure, then, his return to position locking.

In particular, the abutment plane 34 consists of a cage of block 56, under which is formed a retaining rim 57 extending above and transversely to the longitudinal axis of the slide 8 and defining, more particularly, the plane stop 34. In fact, this blocking cage 56 is mounted with a relative mobility transversely in the housing 2, while elastic return means, visible in FIGS. 5, the pushes towards the slide 8. Through this relative mobility the passage of the tongue 31 under the plane stop 34, when the release command of the fitting, is done with greater ease. Indeed, the coefficient of stiffness of the elastic blade that defines the tongue 31 can be determined higher than the coefficient of stiffness of the means of resilient return 58 acting on this locking cage 56. This can be easily pushed back by the tongue 31 during this unlock command, knowing that it is enough less effort to bring back the locking cage 56 and, therefore, the stopped plane 34 in an active position to ensure the function of anti-false maneuver thereafter.

The mounting with relative mobility transversely of the cage of block 56 in the housing 2 is obtained through openings oblong 59 extending transversely at the walls 60 of this cage 56. Moreover, these openings 59 are traversed by an axis 61 held at its ends in holes 62 adjusted accordingly in the side walls 3, 4 housing 2.

As for the control member 55, it consists of a button pusher 63 under which extends a control finger 64 crossing, preferably, the locking cage 56 so able, precisely, to be able to act on the tongue 31 forming retaining finger.

Note that this control finger 64 is split so as to able to span the axis 61 on which is mounted the cage of block 56 in the housing 2. This push button 55 is subject to resilient return means in the rest position, constituted advantageously by the elastic return means 58 acting on said locking cage 56. In fact, these means elastic return means 58 are constituted by a return spring interposed between this locking cage 56 and the inner face to the housing 2 of the push button 63.

Note, again, that it is equipped with a retaining stopper 65 preventing it from extricating itself excessively from the housing 2, under the impulse of these elastic recall means 58.

As visible in the drawings, said push button 63 constitutes the extension of the actuator 7 and is inserted between one end of the latter and the end corresponding to the opening 6 in the fixing plate 5.

Moreover, this opening 6 can be strictly adjusted to this actuator 7 and push button 63, just as at the opposite end of the latter, it may extend beyond said operating member 7 so as to make accessible, in particular in the unlocked position of the slider 8, the needle screw 25 of the bolt carrier. This is the provision that was shown in Figures 1 and 3.

Moreover, it will be noted that the slider 8 can, in the context of such a lock fitting according to the invention, to be easily extended at one and / or the other of its ends 14, 66, by joining means 67 as visible in the figures 7, 8, this to cooperate with junction means 68 of which are equipped with operating rods 69 extending above and / or below the housing 2.

As shown in these FIGS. 7 and 8, such means of junction 67 and the complementary connecting means 68 may adopt different forms of realization. In particular, by their intermediate movement communicated to the slider 8 can transmitted to operating rods 69 extending into perpendicular planes, the latter substantially corresponding to the front edge of the sliding leaf. This allows everything especially, to pass on the controls of the fitting 1 on other locking members, for example other bolts hook, secured to such operating rods 69.
