Description

The invention relates to a locking fitting for a sash sliding comprising a box extending perpendicularly at the rear of a fixing plate provided with an opening access to an operating member for movement control, between a locking position and a position unlocked, at least one slide mounted axially movable in said housing and provided capable of acting at least on a bolt holder.

The present invention relates, more particularly, to the area of locking fittings for sliding sash.

We already know, in particular by the documents FR-2.808.832 and EP-0.044.264 of the locking fittings for sliding door corresponding to the description above. So, such fittings include a housing provided adapted to register in the thickness of the front upright of a sliding leaf, at the back of an interior mounting plate knowing that this fitting can also be fitted with an external plate having, for example, a key element for controlling locking and unlocking.

Anyway, the case of such a fitting sliding door lock is formed, substantially, by said internal fixing plate and two parallel walls extending perpendicular to the rear of this plate, knowing that these walls are provided, substantially up to their free end edge, a return thus delimiting, 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 fixing.

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

This slide acts, as the case may be, directly or at across an empty stroke, on a bolt holder which comprises means for adjusting a hook bolt in position 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 edge of the upright before sliding door.

It is very common to equip this locking fitting an anti-tampering and / or anti-intrusion device. The first is to prevent the hook bolt may be returned by mistake from its locked position in locked position, as long as the sliding sash has not been closed on the sleeping frame. If this should happen, there is obvious, in fact, that when closing the door or window, the hook bolt, previously pushed back into position lock would strike the keeper arranged in correspondence on the sleeping frame, instead of committing to it normally.

The anti-intrusion device is intended to prevent acting directly on a locking member and the hook bolt occurrence, it can be pushed back, from its locked position, to its unlocked position. This would allow a sourfin to penetrate, very easily, in a home.

In some designs and with modifications specific, the action exerted on the slide can be passed on to one or more operating rods extending above or below the housing of the locking fitting, to simultaneously control multiple organs of locking, for example several hook bolts in sight provide multi-point locking.

In particular, we see that the bolt holder on which acts the slide of such a fitting of locking for sliding sash, comes in the form a molded case which is either independent and made integral moving in different ways the slider be done integral part of the latter, also obtained by a process molding.

The first solution of an independent box is the most often adopted when the slide intervenes on the bolt holder beyond an idle stroke, for example, for ordering for unlocking an anti-intrusion device or the like.

Anyway, such a molded latch holder box turns out a significant manufacturing cost. In addition, arises the problem of immobilization, in relation to this bolt holder, of locking bolt, which must still be adjustable to be able to adjust its position according to the location of the strike with which it is intended to cooperate.

In this regard, it has been described in document EP-A-1,258,582, a locking fitting for a sliding leaf of which the recess in the bolt holder, designed to receive the tail of this locking bolt has characteristics specific to ensure this immobilization function.

In particular, in this recess is provided a ramp with which is able to cooperate a toothing that includes the body of the hook bolt and which favors the attachment of this last in the bolt holder to resist any shocks that can undergo, on different occasions, such a fitting for sliding door.

Ultimately, the present invention simplifies the design of such a fitting for a sliding leaf, with a view lower manufacturing cost, without its characteristics are altered.

In particular, the bolt holder, preferably resulting from simple cutting and stamping operations on the slide, is designed to guarantee the immobility of the bolt hook through a perfect isostatic support.

The invention also aims to provide a solution to the problem generally posed by these fittings lock due to their complexity and 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 to respond to congestion problems.

To this end, the invention relates to a locking fitting for a sliding leaf comprising a housing extending perpendicular to the rear of a fixing plate provided an access opening to an operating member for the control in movement, between a locking position and a unlocking position, at least one slide mounted axially movable in said housing and provided capable of acting on less on a bolt holder, characterized in that said bolt holder is defined, at one end of the slide, by a median strip delimited by cutting lines with respect to side bands, the latter and / or said median band being angled at their ends to extend into parallel offset planes and define a transverse light of passage of the tail of a locking bolt, said strips lateral, the median strip and at least one of the ends counter-bent from one and / or the other of these bands constituting at least three isostatic support points.

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

Advantageously, these clamping means are constituted by a screw passing through a threaded opening in the strip median or one of the side bands, so as to cooperate with a locking bolt tail engaged in the transverse light of said bolt holder.

According to another feature of the invention, the bolt holder extends offset towards the inside of the case by relation to the general plan of the slide.

Furthermore according to the invention, the slide results from the cutting and stamping a metal dish.

Furthermore, according to the invention, the housing has walls lateral parallels extending perpendicular to the rear of said fixing plate, these walls comprising a light oblong for the passage of the tail of a locking bolt so as to allow the latter to cooperate with the bolt holder.

According to another feature of the invention, the slide is mounted substantially at the edge of the end and between these walls parallel lateral sides of the housing, so as to close at least partially, the latter at the back and delimit, with the fixing plate, a volume for receiving organs of control and / or security.

According to another feature of the invention, the maneuver is mounted movable transversely to the housing, or perpendicular to the mounting plate, while means are designed capable of transforming this displacement transverse of the operating member in one movement longitudinal axial of the slide.

Particularly advantageously, the slide can be extended at one and / or the other of its ends by means defined junction able to cooperate with junction means complementary associated with operating rods.

The advantages which flow from the present invention consist, basically, in that the slide can be designed by simple cutting and stamping of a metal dish, while incorporating a bolt holder that meets the holding criteria mechanical required for such a locking fitting for sliding door.

In particular, through the very design of this bolt holder, it can be positioned inside the case 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 holder 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 holder.

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

Such a fitting 1 comprises a housing 2 consisting of two parallel walls 3, 4 extending substantially perpendicular to the back of a mounting plate 5. This has an opening 6 allowing access to a operating member 7 for the movement control, between a locked position and an unlocked position, at least minus a slide 8.

Specifically to the present invention, this slide 8 preferably resulting from a cut metal dish and stamped is slidably mounted substantially at the edge of the end free 9, 10 and between the parallel walls 3, 4 of the housing 2. Also, it closes, at least partially, the latter in rear part and defines, with the fixing plate, a reception volume of control and / or safety devices.

In particular, at this end border 9, 10 and on the internal side of this case 2, these parallel walls 3, 4 have grooves 11 for receiving the borders side 12, 13 of the slide 8. Note that these edges 12, 13 of slide 8, so that they can slide in the grooves 11, can be shaped by stamping.

It will be noted that, advantageously, this slide 8 is arched transversely, which improves the rigidity. This camber extends backwards, so towards outside of case 2 and allows to increase so advantageous volume of the latter.

According to another feature of the invention, at one end 14 of this slide 8 is designed, by stamping-cutting, a latch holder 15.

So, symmetrically and parallel to the longitudinal axis 16 of the slide 8 are produced by a stamping tool adapted, cutting lines 17, 18. These define a middle band 19 and side bands 20, 21, the first and / or the latter are bent at their ends 25, so this middle strip 19 and the side strips 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 for this tail 23 of the hook bolt 24. While a third isostatic point consists of at least one of the bent ends of this median strip 19. A needle screw 26 passing through a threaded opening 27 in the middle strip 19 can create, in this case, the fourth isostatic point. It is note that the tail 23 of the hook bolt 24 can be notched on its side edges, notches with which it is able to cooperate with this needle screw 26, so as to ensure perfect axial immobilization of this hook bolt 24.

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

Advantageously, again, the bolt holder 15 extends from offset to the inside of the housing 2 relative to the general plane of the slide 8, while the parallel walls 3, 4 of this box 2 comprise, in line with this bolt holder 15, an oblong light 28 intended, here again, for the passage of the tail 23 of the hook bolt 24. In sum, such a light 28 ensures perfect retention of the whole in the volume of the box 2 and participates in the good behavior or maintenance of the bolt hook 24 in the bolt holder 15.

It will be observed that the fact of shifting towards the inside of the case 2 the bolt holder 15 leads to bring it closer to the plate attachment 5, which results in better recovery of forces printed on the fitting 1 through the bolt 24.

For the same purpose, the offset between the plane of the bolt holder 15 and that of the slide 8 results from a double folding 8A in "S" printed on the latter, with a first elbow 8B extending between the grooves 11 and up 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 slide 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 completely particular manner according to the invention, in the slide 8 are cut and folded more or less inside the housing 2, one or more tabs 29, 30, 31 capable of defining, as the case may be:

control fingers to ensure the movement of this slide 8, between its locked position and its unlocked position;

and / or provided locking fingers capable, in cooperation with abutment planes 32, 33, 34, of designing, as the case may be, an anti-intrusion device 35 and / or an anti-tampering device 36.

According to another feature of the invention, the maneuver 7 is designed capable of moving transversely to the case 2 in opening 6, either perpendicular to the plane of the slide 8, while means 37 are provided for transform this movement of said operating member 7 into a longitudinal axial displacement of this slide 8.

Thus, the operating member 7 is superimposed on the slide 8, guide 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 side walls 3, 4 of this housing 2, by oblong transverse openings 39, 40 in which is able to come to engage, in particular resiliently, a guide pin 41 which comprises each of the side walls 42 of this operating member 7.

In addition, it 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 from the slide 8.

More precisely, the operating member 7 has on its side oriented towards this slide 8, one or more stops 43, 44 based on these inclined planes 45, 46 defined by said tabs 29, 30. Thus, under the effect of a pressure exerted on this operating member 7 and the action of said edges 43, 44 on these inclined planes 45, 46, this results in a displacement longitudinal of slide 8. Obviously the direction of movement communicated to the latter depends on the orientation of the plans inclined 45, 46. Preferably, these are oriented so that under the effect of a pressure exerted on the operating member 7 this results in the unlocking of the fitting 1.

The reverse displacement advantageously results from the action of elastic return means not shown in the drawings. Of such elastic return means can act directly on the slide 8 to, for example, be stressed during the unlocking command. Also, by coming to release the action on the operating member 7, these return means elastic push the slider 8 into position locked. The interaction between the inclined planes 45, 46 and the edges 43, 44 has the effect of bringing, simultaneously the operating member 7 in its rest position.

Advantageously, at least one of these same tabs 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 stop plane 32, 33 to oppose, from a locking position, to a possible attempt to unlock fitting 1 by direct action on the hook bolt 24 and thus constitute the device burglar resistant 35.

It is illustrated by the arrow referenced 51 in Figure 6 a such action which would be directly reflected on the slide 8. As can be seen, the end edge 49, 50 of the tongues 29, 30 then meets these stop plans 32, 33. These are defined, in the design according to FIG. 6, in particular by recesses 52 at the free end of edges of retainer 47, 48 extending under the operating member 7. This the latter being, here, in its rest position, it cannot to extract itself more from the case 2 and thus opposes this displacement. It will be noted, in particular, that these retaining edges 47, 48 are oriented opposite to tabs 29, 30.

In fact, such retaining edges 47, 48 can, if necessary, constitute lifting blocks which, coming from extend under an inclined plane 45, 46 when ordering unlocking, can intervene, in the manner of edges 43, 44, on this inclined plane 45, 46 to push the slide 8 back 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 used under stress by exerting pressure on this organ of operation 7.

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

As already specified above, this anti-fake device maneuver 36 is constituted, on the one hand, by a tongue 31 axially cut in the slide 8 and pushed back to the interior of the housing 2 so that this tongue 31 define a locking finger. Specifically, the end free 53 of this tongue 31 is thus oriented and offset by relative to the plane of the slide 8 so as to form a step in the direction of movement of the lock, represented by arrow 54.

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

Finally, this anti-false operation device 36 is completed by a release 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 step, in front of the stop plane 34. The elastic return means slide 8 then ensure its return to the position of locking.

In particular, the abutment plane 34 consists of a cage blocking 56, under which a retaining edge 57 is formed 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. 1 and 5, pushes it back in the direction of the slide 8. Through this relative mobility the passage of the tongue 31 under the plane stop 34, during the command to unlock the fitting, is carried out with greater ease. Indeed, the coefficient of stiffness of the elastic blade defined by the tongue 31 can be determined greater than the stiffness coefficient of the means of elastic return 58 acting on this blocking cage 56. It can therefore be easily pushed back by the tongue 31 during this unlocking command, knowing that it suffices with less effort to bring back this blocking cage 56 and, therefore, the stop plane 34 in an active position in order to ensure the function of anti-false operation thereafter.

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

As for the control member 55, it consists of a button pusher 63 under which extends a control finger 64 preferably passing through the blocking 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 ability to step over axis 61 on which the cage is mounted blocking 56 in the housing 2. This push button 55 is subjected to elastic return means in the rest position, advantageously constituted by elastic return means 58 acting on said blocking cage 56. In fact, these means elastic return 58 consist of a return spring interposed between this blocking cage 56 and the internal face to the housing 2 of the push button 63.

Note, again, that the latter is provided with a retaining stop 65 preventing it from being extracted excessively from the housing 2, under the impetus of these elastic return means 58.

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

Furthermore, this opening 6 can be strictly adjusted to this operating member 7 and said push button 63, just like at the opposite end of the latter, it can extend beyond said operating member 7 so as to make it accessible, in particular in the unlocked position of the slide 8, the needle screw 26 of the latch bolt 15. This provision was shown in Figures 1 and 3.

In addition, it will be noted that the slide 8 can, in the context of such a locking fitting according to the invention, 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 in order to cooperate with joining means 68 which are fitted with operating rods 69 extending above and / or below the housing 2.

As shown in these figures 7 and 8, such means of junction 67 and the complementary junction means 68 can adopt different embodiments. In particular, by their intermediary the movement communicated to the slide 8 can be transmitted to operating rods 69 extending in perpendicular planes, the latter corresponding substantially to the edge before the sliding sash. This allows everything in particular, to pass on orders for fitting 1 on other locking members, for example other bolts hook, integral with such operating rods 69.
