Description

rear upright (10) of said sliding leaf (2).

1 2826997

  The invention relates to an anti-lifting device for

  sliding door, window or the like.

  The present invention relates to the field of building hardware and relates, in particular, to fittings for sliding leaves. In the context of a door, window or the like, comprising at least one leaf mounted to slide on a sleeping frame, it is usual for said leaf to have, in a vertical direction, relative mobility relative to the sleeping frame to allow

its hanging on the latter.

  Obviously, this relative mobility must be condemned, in particular once the leaf closed and locked on the sleeping frame, otherwise breaking into a dwelling would hardly pose any difficulties insofar as it would suffice to lift said leaf from the outside. and, finally, by a

  reverse operation, unhook it from the frame.

  Most of the time, this anti-lifting function is ensured through the locking fitting which comes to equip

such a sliding leaf.

  Usually, this fitting is associated with the front upright of this leaf and comprises a locking member, for example a hook bolt, provided capable of cooperating with a keeper formed on the corresponding upright of the sleeping frame, after closing the door or window. In the end, it is through the upward orientation of the hook that we come to prevent, once the fitting

  locked, lifting the leaf.

  Obviously, there are different embodiments of locking members making it possible to achieve this result, that is to say, not only guaranteeing the correct locking of the leaf on the frame.

  dormant, but, moreover, preventing that one can unhook it.

  If, thanks to such a locking fitting, this vertical mobility relative to the sleeping frame, of the sliding leaf can be annihilated at the height of the upright before the latter, it is not the same at the level of the opposite upright, so that, in the event of an attempted break-in, this leaf can be brought at an angle. This has

2 2826997

  as a consequence of creating, between the lower crosspieces, respectively, of the latter and of the sleeping frame, side opposite to the locking fitting, a clearance which may be sufficient for the insertion of a tool, for example a crowbar , a screwdriver or other, to force the carpentry. I1 is also known to install anti-lifting wedges at the upper cross member of the fixed frame, more particularly in the guide rail of the leaf. However, to allow the assembly and disassembly of the leaf, these shims are necessarily arranged on the side of the upright of the frame against

  which closes the leaf.

  Also, such shims, if they prevent an attempted break-in by lifting the sliding leaf from having an integral effect on the locking members, they do not allow

  not to respond to the problem posed.

  This exposed, it will be noted, moreover, that if within the framework of a pivoting door or window, an opening can be provided with a fitting, of the type cremone bolt or cremone bolt, with perimeter locking, ie intervening , if necessary, both at the level of the front upright of this opening and at the level of the crosspieces, or even along the rear upright, in the case of a sliding leaf this type of locking, even with the use of such a cremone bolt or cremone bolt, can only be envisaged by implementing more complex systems which, although reliable, are not applicable to all designs of sliding sash or do

  do not meet the needs and would therefore be too expensive.

  Also, it is customary to act exclusively on the front upright of this leaf, seeking to guarantee its locking with respect to the corresponding amount of the sleeping frame, at best, also, with respect to the lower and / or upper cross member of

this last.

  In particular, it is known to provide this front upright of the leaf with a lever whose control mechanism makes it possible to act on at least one operating rod extending above and / or below a central housing. . In the locked position, the free end of this operating rod, disposed along the

3 2826997

  front upright of this sliding leaf, is able to be projecting relative to the cross member, as the case may be, upper or lower of the latter, so as to come to cooperate with a keeper which is in turn equipped with the sleeping frame , at its upper, or even lower, cross-member. If, in itself, such a design is satisfactory insofar as it effectively confers on the door or window, an additional degree of security against an attempted break-in intended to force the sliding of the leaf in the sense of openness, it only prevents due to the use, during such actions, of increasingly efficient tools, this solution may prove to be insufficient. In all cases, such an attempted break-in may cause deformations at the level of the locking members, or even, possibly, a play of the leaf relative to its sleeping frame, detrimental to the proper functioning of

  said door or window later.

  Ultimately, the invention aims to remedy the aforementioned drawbacks through an anti-lifting device for sliding door leaf, window or the like, which is able to assist, in a complementary manner, the locking fitting fitted, usually, this leaf, this in this anti-lifting function, but also in its primary locking function. Also, this anti-lifting device, in accordance with the invention, comprises a prewept keeper capable of being attached to the edge of an amount of said sliding leaf and comprising an opening extending in a direction perpendicular to the plane of this leaf and in which is prewe able to come to engage, under the action of elastic return means and by displacement in the same direction, a locking finger slidably mounted in a housing associated in correspondence with the frame or a sliding leaf

  adjacent to said door, window or the like.

  The invention also relates to a door, window or the like comprising at least one leaf mounted to slide on a fixed frame and having a front upright equipped with a locking fitting, characterized in that it comprises a device for anti-lifting

4 2826997

  the above features associated with the rear upright of said

sliding leaf.

  Other objects and advantages of the present invention

  will appear during the description which follows relating to

  to an embodiment which is given only by way of example

indicative and not limiting.

  Understanding this description will be facilitated by

  referring to the attached drawings, in which: - Figure 1 is a schematic representation of a window provided with two leaves, at least one of which is slidably mounted on the frame, this leaf receiving, in particular, '' anti-lifting compliant

to the invention.

  - Figure 2 is a detail w e of Figure 1 illustrating an anti-lifting device in its inactive position; - Figure 3 is a view similar to Figure 2 showing the anti-lifting device once made active; - Figures 4 and 5 show, in these same inactive and active positions, the conforming anti-lifting device

to the invention.

  As shown in Figure 1 of the accompanying drawings, the present invention relates to the field of sliding doors or windows. Thus, such a door or window 1 comprises one or more leaves 2, 2A of which at least one is slidably mounted on a frame 3. More particularly, this sliding leaf 2 comprises, usually at the height of its front upright 4 located on the side o the opening takes place, a locking fitting 5 which, through an appropriate control mechanism, acts on at least one locking member, such as a hook bolt capable of cooperating with a keeper attached to the upright

correspondent 6 of the frame 3.

  If, in a usual manner, such a locking fitting 5, once locked, prevents the leaf 2 from being able to be lifted relative to the sleeping frame 3, this up to its front upright 4, the invention relates to everything particularly, a

2826997

  anti-lifting device 7 capable of assisting, so

  complementary, this locking fitting 5.

  Thus, this anti-lifting device 7 comprises a keeper 8 which can be seen represented in FIGS. 2 to 5, which is very particularly suitable for being attached to the edge 9 of an upright

sliding leaf 2.

  This keeper 8 has an opening 11 extending in a direction 12 perpendicular to the plane of the door or window 1 and in which is able to come to engage, under the impulse of elastic return means 13 and by displacement in a identical direction 12, a locking finger 14. This is slidably mounted in a housing 15 associated, in correspondence, with the sleeping frame 3 or

  to another leaf 2 adjacent to this door, window or other 1.

  In essence, such an anti-lifting device 7 equips the rear upright 10 of the sliding leaf 2, opposite the

  front upright 4 provided with locking fitting 5.

  According to an advantageous embodiment, said keeper 8 comprises a fixing plate 16 through which it is provided capable of being attached to the edge 9 of this rear upright 10 of the sliding leaf 2. On this fixing plate 16 is provided, parallel to direction 12, either perpendicular to the plane of the door or window 1, at least one guide and retaining ledge 17 above which extends the opening 11 intended to

receiving said locking finger 14.

  For questions of reversibility of this keeper 8, the latter adopts a symmetrical configuration and comprises at its fixing plate 16 a second guiding and retaining twist 18 arranged parallel to the first 17 and delimiting with the latter and in combination with said fixing plate 16, a channel 19

  corresponding to said opening 11.

  As shown in Figures 3 and 5, the locking finger 14, coming to be registered between the two guide and retaining retorts 17, 18 placed at different levels along the rear upright 10 of the sliding leaf 2, prevents that -to move,

  vertically, relative to the frame 3.

6 2826997

  So as to allow the connection of this keeper 8 at the edge 9 corresponding to the rear upright 10 of the sliding leaf 2, said fixing plate 16 has openings, not shown, for the passage of fixing members, such as screws or Similar. In particular, such openings and the fixing members that they receive are prews capable of being erased under covers 20, coming to define, advantageously, extensions of the guide and retaining edges 17, 18. Preferably, these covers 20 are made of a material, for example rubber, capable of absorbing the shock resulting from the meeting of the rear upright 10 of the sliding leaf 2 with any obstacle,

  in particular, the corresponding rear upright 21 of the sleeping frame 3.

  Thus, this keeper 8 advantageously replaces the rubber buffers which are usually fitted to this rear upright.

21 of the frame 3.

  To return to the locking finger 14 and more particularly to its housing 15 in which it is slidably mounted, the latter can be designed so as to be embedded in the joinery. Thus, in the case of a door or window having only one sliding leaf, the rear upright of the latter may, once the door or window closed, be located in correspondence with an amount of the sleeping frame, so that in

  the latter can be integrated this box 15.

  Furthermore and as illustrated in the figures of the attached drawings, this box 15 can, again, be engaged in a housing prew for this purpose in the upper crosspiece 22, even lower 23 of an adjacent leaf 2A, suitably, when the door or window is closed, to present the locking finger 14 which it receives in line with a keeper 8. The latter is therefore located along the edge 9 of the rear upright 10 corresponding to the sliding leaf 2, substantially at the upper end or as appropriate

lower of the latter.

  To facilitate this embedding, the box 15 can be defined in a tuEular form making it easier to design the housing prew capable of accommodating it. Furthermore, it is advantageously reported to

7 2826997

  the back of a faceplate 24 through which it can be made integral with the joinery. Thus, just as for the strike plate 8, at the level of this face plate 24 can be made openings for the passage of fasteners, such as screws or the like. Furthermore, this anti-lifting device 7 comprises means 25 provided capable of retaining the erased locking pin 14 in its housing 15, against the action of the elastic return means 13, means 25 themselves under the stress of 'An elastic member 26 for systematically pushing them into an active position for retaining the locking finger 14. In addition, these means 25 are manually unlocked to release the locking finger 14 and thus make active the anti-lifting device 7. These means 25 consist of a latch 27 slidably mounted in a groove 28 formed in the head plate 24, this in a direction perpendicular to the direction of movement of the locking finger 14. More particularly, one of the free ends 29 of this latch 27 is provided capable of extending, under the impulse of the elastic member 26, in the housing of the housing 15 receiving the locking finger 14 to cooperate with the latter and maintain it

  cleared in relation to keeper 8, this when the anti-

uplift 7 is made inactive.

  More particularly, this free end 29 of the latch 27 is capable, in this inactive position of the anti-lifting device 7, coming to be positioned in front of a retaining stop 30 which comprises, substantially at its emerging end 31,

the locking finger 14.

  According to a preferred embodiment, this retaining stop 30 is formed in the bottom 33 of an axial groove 32 that includes the locking finger 14, knowing that at the rear of this retaining stop 30, in the direction of the housing 15, this bottom 33 of said axial groove 32 has a slope from the top defined by said retaining stop 30. Thus, when, starting from the position illustrated in FIG. 3 or again in FIG. 5, the locking finger 14, initially engaged in keeper 8, is

8 2826997

  pushed back into its housing 15 to return to its inactive position corresponding to FIGS. 2 and 4, the free end 29 of the latch 27 cooperates with this bottom 33 with a slight slope of the groove 32, having the effect of pushing said latch 27 back into a retracted position inactive, against the action of the elastic member 26 and, ultimately, to allow the crossing at the end 29 of this latch 27 of said retaining stop 30. Ultimately, once it is exceeded, this latch 27 automatically returns to its active position under the action of the elastic member 26, that is to say that its free end 29 is positioned in front of the retaining stop so as to keep the locking finger 14 erased in the

housing 15.

  It will be noted that through this design, the latch 27 is systematically erased at the rear of the faceplate 24, whether it is in the active position in which it maintains the locking finger 14 erased in the housing 15 or when this finger blocking

  14 is. on the contrary, protruding and that the anti

  uplift 7 is. himself, active.

  Obviously, to make the anti-lifting device 7 active again, starting from the position described above, it suffices, manually, to remove the latch 27, so as to release its free end 29 from the stop of restraint 30. For this this latch 27 comprises, moreover, gripping means 34, for example a tranevereal twist to its axis of movement made accessible through a light 35 in the headrest plate 24, communicating with the groove 28 in which is slidably mounted

this latch 27.

  It will be noted that insofar as the emerging end 31 of the locking finger 14 is directly accessible, its retreat in the

  housing 15 can be obtained manually and by direct action.

  As is apparent from the above description, the present

  invention makes it possible to respond effectively to the drawbacks of the state of the art. In addition, it will be noted that an anti-lifting device 7 thus designed is capable of equipping, at

  retrospectively any sliding door or window.

9 2826997

  Obviously, by multiplying the number of these anti-

  lifting 7 along a rear upright 10 of a leaf

  sliding 2 a multiple locking of the latter is obtained.

  Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited thereto and that there can be made various modifications to the forms, materials and combinations of these. various elements without

  for that to move away from the framework and the spirit of the invention.
