Description

1 2775312

  The invention relates to an intermediate security device for a door or window comprising at least one opening pivotally mounted by means of articulation means on a frame, this device comprising a sole secured to the frame and serving as a keeper for a finger for attaching a mobile element integral with the opening. The present invention will find its application in the field of building hardware and, more particularly, that

  hinge fittings for door, window or the like.

  It is a fact that works such as doors, windows or the like, which are either old or of great height, or weakened by uprights of small section or fatigue of materials and equipment, and the opening of which is pivotally mounted on the frame, have certain weaknesses both in terms of the quality of the seal they provide and their

  resistance to attempted break-in.

  If we have already been able to respond effectively to these drawbacks, in particular by the use of locking fittings with multiple locking points, this is mainly on the side opposite the hinge axis of these doors or windows. , problems arise to guarantee this seal and improve the mechanical strength at the pivoting mounting of the opening on its frame. Very often, the solutions previously adopted either were able to make up for the play between the sash and the frame to guarantee the compression of a peripheral seal when closing the door or window, or contributed to a certain improvement, from the point of view of their mechanical strength, of the opening and of the frame, in particular towards a

attempted break-in.

  Anyway, these known solutions frequently use complex means necessarily fitted with adjustment means, besides that they are currently only suitable

  a given mode of pivoting of the opening relative to its frame.

  In fact, to date, there is no universally solution

2 2775312

  applicable that is not complex because of many facts

technical generators.

  Thus, by way of example, it is known, in particular from document FR-A-2. 649.439, an intermediate bearing for window or other, comprising a fixed sole made integral with the frame and provided with a light in which engages a latching finger of a movable element integral with the opening. This intermediate bearing comprises adjustable articulation means for modifying the attachment zone perpendicular to the amount of the frame.

  between the movable element of the fixed base.

  More specifically, said articulation means are in the form of an articulation axis housed in a vertical bore produced in the fixed sole. This articulation axis is located, substantially, on the axis of the pivoting of the opening relative to the frame. As for the adjustment means, they can be in the form of an eccentric located on the aforementioned articulation axis and the two extreme positions of which, obtained according to a rotation of 1800, constitute the amplitude of adjustment of the zone of hooking and, therefore, the amplitude of the compression of the door against the frame. In another embodiment, the attachment finger is itself of an adjustable nature. In fact, the very design of such an intermediate bearing requires it to be applied on the frame, while the mobile element comes, for example, to be fixed on the edge of the covering strip equipping the rear upright of the opening. Also, if such a bearing responds to the problem of the compression of the peripheral seal of a door or window when closing the door on the frame, it is impossible for it to provide real reinforcement of the mechanical strength of the hinge fittings during an attempted break-in, for example at

crowbar.

  The document DE-U-84 15 163.3 describes a similar solution except that the movable element and its hooking finger come, here, to be fixed in the rebate of the opening, while the fixed sole

3 2775312

  is in the form of a housing coming to be housed in a notch practiced at the level of the internal face of the frame. It does not remain about it less than at the level of this fixed sole intervenes an articulation axis maintained, at the level of its ends, in bearings and being located, appreciably, on the pivot axis of the opening relative to its dormant. On this articulation axis is mounted an eccentric which acts on an intermediate device which is, therefore, adjustable perpendicular to the plane of the door or window. On this intermediate device, the hooking finger is supported when closing the door to press

this one against the frame.

  As for document DE-U-90 10 551.6, it also describes an intermediate bearing applied on the inside of the opening and the frame. In fact, the device described here involves, at the movable element, hooking means able to pivot around complementary hooking means

  associated with the fixed sole made integral with the frame.

  In the end, it is clear from this state of the art that priority has been given, until now, to the compression of the opening relative to the frame when closing the door or window, at the using devices making

  often use complex means of adjustment.

  In addition, existing solutions are applicable to a

  determined mode of pivoting of the sash relative to the frame.

  More precisely, in most cases, the positioning of the parts is intimately linked to that of the axis of

pivoting of the door or window.

  Ultimately, the bearings and other existing devices had little function to increase, simultaneously, the mechanical strength of these doors or pivoting windows with respect to a

attempted break-in.

  The present invention has proposed, precisely, to provide a simple, universal solution, requiring no external intervention because self-adjusting. To this end, the invention relates to an intermediate safety device for a door or

4 2775312

  window, comprising at least one opening pivotally mounted by means of articulation means on a frame, this device comprising a fixed sole secured to the frame and serving as a keeper for a finger for hooking a movable element secured to the opening, characterized in that the movable element comprises a fixing plate capable of being fixed in the rebate of the opening, while the sole is added in the rebate of the frame, the attachment finger being in the form of a curved blade, according to a radius of curvature determined around a substantially parallel axis while being offset relative to the pivot axis of the opening, suitably, when closing the door or window and through its cooperation with the striker of the sole

  fixed, to ensure compression of the sash against the frame.

  Insofar as both the fixing plate of the mobile element and the fixed base are fixed in rebate, respectively, of the sash and the frame, their fixing members can come to be housed in the same thickness of the component profiles this opening and the frame so that they offer resistance to tearing, in particular against a force perpendicular to the plane of the door or window, particularly important. Note that the fixing plate of the mobile element can receive, if necessary, a fixing shoe capable of taking position in a groove which are usually provided with the amounts and crosspieces of these doors or windows when these are designed by metallic or synthetic type profiles. Thus, such a fixing shoe advantageously contributes to increasing the rigidity of the profile in which it

comes to stay.

  Likewise and as will appear in the figures of the attached drawing, the blade defined by the attachment finger corresponding to the movable element, can, not only, penetrate into a light which serves as a keeper at the level of the fixed sole, but also in the thickness of the profile making up the frame. Thus, as part of a reinforced plastic profile, this

2775312

  blade can engage in the metal reinforcement integrated into said audit

  profiled to improve the grip it provides.

  Ultimately, such a device is capable of ensuring a catch-up of a given amplitude, in a direction perpendicular to the plane of the door, window or the like, between the leaf and the frame, this with great ease which that the resistance provided by a peripheral seal. Also, this intermediate safety device, being self-adjusting, can be dispensed with any adjustment means,

  necessarily complex, but also able to get out of balance.

  It is still a feature of the present invention, as

  that will become apparent from the following description, namely that the

  intermediate safety device has characteristics which are independent of the mode of pivoting of the leaf relative to the frame and give it a certain universality of application. Indeed, the pivot axis of the opening can be in rebate, just like it can be slightly offset on the internal side of the door or window to ensure a certain projection outside the frame of the opening, particularly when the latter is provided with a covering strip. Finally, through their rebate layout, the height of the fixed base, like that of the fixing plate of the mobile element can be arbitrary and, a fortiori, they can be relatively large, which allows them to significantly improve the mechanical strength of a door or

  window regarding attempted break-in.

  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 better understood by

  referring to the attached drawing, in which:

6 2775312

  - Figure 1 is a partial schematic representation in section of an opening and the frame of a door, window or the like, this up to the pivot axis of the latter, in this figure being illustrated schematically, the intermediate safety device according to the invention; - Figure 2 is a view similar to Figure 1, the opening being, here, being closed on the frame, causing the engagement of the latching finger corresponding to the movable element of the intermediate safety device with the fixed sole made integral with the frame; - Figure 3 shows schematically and elevation of the fixing plate of the movable element; - Figure 4 illustrates schematically and elevation of the fixed sole serving as a keeper for the attachment finger fitted

the movable element.

  The present invention relates to an intermediate safety device 1 for door or window, the opening 2 of which is pivotally mounted on a dormant frame 3 by means of articulation means which, which may be any, have not been

  represented in the figures of the attached drawing.

  In this regard, in the context of Figures 1 and 2 of these drawings, only the sections 4 and 5 corresponding to this opening 2 and to this frame 3 and extending in the immediate vicinity of the axis of

  pivoting of the door or window, have been shown.

  It should be noted, in particular, that the intermediate safety device 1, which is the subject of the invention, will find its utility whatever the location of this pivot axis, in rebate 6 or 7 is applied. This latter solution corresponds more, in the embodiment illustrated in FIGS. 1 and 2 insofar as the opening 2 is, here, provided with a peripheral covering strip 8 intended to come into contact with the internal face 9 of the frame 3. In fact, in Because of such a covering strip 8 it is necessary to project, slightly, this opening 2 on the outside of the frame 3 so that it does not interfere with the opening of

door, window or the like.

7 2775312

  Again, in the absence of such a covering strip 8, this pivot axis could be located in rabbet 6 without this calling into question the distinctive characteristics of the intermediate safety device 1, object of the invention and which will now be described. Thus, this device 1 comprises a fixed sole 10 made integral with the rebate 6A of the frame 3 and serving as a keeper for a fastening finger 11 of a movable element 12 which, for its part, is fixed to

opening it 2.

  In fact, according to the invention, the movable element 12 essentially comprises a fixing plate 13 capable of being fixed in the rebate 6B of the opening 2. From this fixing plate 13 extends the catching finger 11 which, advantageously, is in the form of a blade 14 curved according to a radius of curvature 15 about an axis substantially parallel while being offset with respect to the pivot axis of the opening 2 relative to the frame 3. More precisely, this curved blade 14 which is, according to a preferred embodiment of the invention, cut out from one of the longitudinal edges 17 of the fixing plate 13, is inserted, gradually, at the time of closing the opening 2 on the frame 3, in a slot 18 serving as a keeper formed in the fixed sole 10 attached to the frame 3. Note, in this regard, that the free end 19 of this blade 14 as the surroundings of the light 18 can be chamfered for

facilitate the aforementioned commitment.

  In addition, the length of this blade 14 can be defined so as to allow it to extend, widely, beyond the lumen 18 of the fixed sole 10 in the thickness of the profile 5 corresponding to the frame 3. If this undoubtedly leads to better attachment, and therefore to better mechanical strength of the assembly in the event of an attempt to break in at the crowbar, in the very particular context of a profile 5 of synthetic material comprising, internally, a reinforcing profile 20, as illustrated in FIGS. 1 and 2, this blade 14 can

8 2775312

  extend through this reinforcing profile 20 which then includes a light 21 allowing this passage of the blade 14 to the right

  light 18 in the fixed sole 10.

  It should be observed that if this non-materialized axis around which the blade 14 is bent along a radius of curvature 15, extends substantially parallel to the pivot axis of the opening relative to the frame 3, it persists between them a determined offset so as to allow the blade 14, in cooperation with the fixed sole 10 which serves as a keeper, to ensure this compression of the leaf 2 against the frame 3, this in a progressive manner at the very moment of close the door, window or the like. In fact, it is precisely because this offset is necessary that the exact positioning of the pivot axis of the opening is of little importance. This gives this intermediate security device its universal character with regard to its application, but also its property.

auto - tuning.

  To return to the fixing plate 13, the latter has one or more openings 22 for the passage of fixing members, such as screws, rivets or the like. Note that such openings 22 can be defined in an oblong shape, to allow a certain adjustment of this fixing plate in particular in a direction perpendicular to the plane of the opening and / or to give this fixing plate the possibility of easily adapt to the positioning of the openings for the passage of fixing screws or the like,

opening 6B rebate 2.

  It will be observed, in particular, that being disposed in rabbet 6B of the opening 2, such a fixing plate 13 does not pose any aesthetic problem. Also, it can be dimensioned widely both in height and in width, the latter being however limited with respect to the depth 23 of this

opening 6B rebate 2.

  As can be seen in FIG. 3, such a fixing plate 13 can then comprise two parallel rows of opening 22

9 2775312

  intended for the passage of fixing screws or the like. Under these conditions, it is able to offer perfect mechanical resistance in the event of an attempted break-in and therefore tearing away from the

crowbar.

  It should be noted that a mounting plate 13 of considerable height can significantly increase the inertia of the profile 4 on

which it is fixed.

  In this regard, it is usual, in the case of doors or windows designed in metal profiles or in synthetic material, that the profiles 4 making up the leaf 2 comprise, in rebate 6B, a T-groove 24 in particular capable of accommodating certain organs a locking fitting. Under these conditions, this fixing plate 13 can be equipped with a fixing and consolidation shoe 25 able to extend in this groove 24 and, therefore, of form adjusted to the latter. Such a shoe 25, if it extends substantially over the entire height of the fixing plate 13, contributes not only to a better resistance to tearing of the latter, but, moreover, comes to improve there.

  again, the inertia of the profile 4 corresponding to this opening 2.

  It is understood, of course, that if the fixing plate 13 corresponding to the movable element 12 of the intermediate safety device can be greatly oversized due to its implantation in the rebate 6B of the opening 2, the same applies to the blade 14 defining the attachment finger 11 and, of course, the

  fixed sole 10 made integral with the frame 3.

  As is apparent from the above description, through

  of its particular configuration, the latching finger 11 in the form of a blade 14 has the function: - of ensuring a perfect seal between the leaf 2 and the frame 3, in particular by compressing the latter against each other , when closing the door, window or the like; - And to improve the mechanical resistance of this door, window or the like with regard to an attempted break-in, for example at the crowbar, carried out at the level of the pivot axis of the leaf 2 by

relative to the frame 3.

2775312

  However, according to the invention, this fastening finger 11 can also be provided capable of limiting the rebate clearance of the opening 2 relative to the frame 3, this with respect to a movement of this opening 2 in the plane of the door, window or the like, parallel to the pivot axis. This result can be obtained by giving the blade 14 an inclination at an angle α determined with respect to the axis of the fixing plate 13, the lumen 18 in the fixed sole 10 also being inclined under these conditions according to a mame angle al, as marked in the

figure 4.

  It is still possible to obtain better results by having, along the sections 4 and 5 of the opening 2 and of the frame 3, two intermediate safety devices 1, the blade 14 corresponding to the movable element 12 of a intermediate safety device 1 being inclined at an angle P substantially symmetrical to the angle of inclination a of the blade 14 corresponding to the movable element 12 of the other intermediate safety device 1. It is obvious that, by the same way, the light 18 in the fixed base 10 will be inclined correspondingly at an angle respectively P1 or al. Finally, it can be seen that such an intermediate safety device, in accordance with the invention, is also capable of opposing a displacement in the plane of the leaf 2 relative to the frame 3, displacement generated , for example, by

  through a crowbar.

  As is apparent from the above description, the

  intermediate safety device 1, according to the invention, although being of simplified configuration, is able to provide

  a real answer to the problem posed.

  Although the invention has been described with reference to a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to the forms, materials and combinations of these. various elements,

  without departing from the scope and spirit of the invention.
