Description

The present invention relates to a device for correcting the vertical deflection of an upper rail of the joinery of a door, window or the like. This invention also relates to a shutter box, intended to be mounted and fixed on an upper rail of the joinery, and comprising such a vertical deflection correction device. This invention relates to the field of the building and, more particularly, that of the manufacture of closure systems of an opening that comprises the masonry of a building. This invention will find a particularly suitable application in the context of a closure installation comprising, on the one hand, a closure system in the form of a door, window or the like and, on the other hand, a concealment system under form of a roller shutter equipping such a closure system. We already know, closing systems in the form of a door, window or the like. Such a closure system comprises, on the one hand, a joinery comprising at least lateral uprights, a bottom rail and an upper rail and, on the other hand, at least one opening mounted on the carpentry, as the case may be, pivoting or in translation. This carpentry is positioned in an opening that includes the masonry of a building and is secured to this masonry by fixing the lateral uprights and cross members on the masonry. In the context of a closure system comprising such a closure system and an obscuration system in the form of a shutter, the occultation system comprises a box surmounting the top rail of the closure system. This configuration does not make this upper crosspiece integral with the masonry. Although the box is usually attached to the upper crossbar, this box does not have sufficient rigidity to overcome deformation, caused by a horizontal stress exerted on the closure system (wind, attempted break-in), and detrimental appropriate closure and opening of this system. One solution has been found and consists in horizontally reinforcing the upper rail with a steel tube engaged inside this upper rail. However, such a solution requires a joinery whose dimensions can accommodate such a tube which is not the case of aluminum joinery. For a PVC joinery, this solution is acceptable but only for a short closing system. On the other hand, for a closure system of great length (for example a sliding door), this solution is by no means sufficient. Also, it was imagined a horizontal reinforcement in the form of a horizontal steel plate mounted and fixed on the upper rail of the joinery. However, under the effect of its own weight, this steel plate flexes vertically and weighs on the upper crossbar which undergoes a vertical deformation and which then has a vertical arrow preventing the opening and closing of the closure system.

The present invention aims to overcome the drawbacks of closure installations of the state of the art. To this end, the invention relates to a device for correcting the vertical deflection of an upper rail of the joinery of a closure system. This device 25 comprises: - a vertical reinforcement, extending horizontally, intended to extend substantially parallel to the upper rail of the joinery and to be immobilized with respect to this joinery; At least one base intended to cooperate with the upper rail of the joinery; at least one means for adjusting the vertical position of such a base relative to the vertical reinforcement. The invention also relates to a rolling shutter box 35 intended to be mounted and fixed on an upper rail of the joinery of a closure system. This box is characterized in that it comprises a device for correcting the vertical deflection of the upper rail of the joinery, this device having the characteristics described above.

Finally, the invention relates to an installation for closing an opening presented by the masonry of a building, this closure system comprising, on the one hand, a closure system in the form of a door, window or the like incorporating a joinery with at least side jambs and a top rail and, secondly, a concealment system incorporating a shutter box mounted and fixed on the top rail of the joinery of the closure system. This installation is characterized by the fact that the rolling shutter box has the characteristics described above. Thus, the invention relates to a device for correcting the vertical deflection of an upper rail of the joinery of a door, window or the like. This device comprises a vertical reinforcement immobilized with respect to the joinery (more particularly with respect to the lateral uprights of this joinery), a base intended to cooperate with the upper rail of the joinery and means for adjusting the vertical position of this base by compared to the vertical reinforcement. These adjustment means then make it possible, advantageously and in the event of a vertical deflection of the top rail of the joinery, to exert an ascending traction on the base and, therefore, on the upper cross member cooperating with this base, this with a view to back this base and, therefore, this upper crossbar which allows to correct or cancel, the vertical arrow of the upper rail. Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

The understanding of this description will be facilitated with reference to the accompanying drawings in which: FIG. 1 is a schematic and perspective view of a closure installation according to the invention; - Figure 2 is a schematic view corresponding to a detail of the closure system illustrated in Figure 1; FIG. 3 is a diagrammatic, side and cross-sectional view of the closure system illustrated in FIGS. 1 and 2. The present invention relates to the field of the building and, more particularly, to the manufacture of closure systems. an opening in the masonry of a building. Such a closure installation 1 comprises a closure system 2 adopting the shape of a door, a window or the like. Such a closure system 2 then comprises a joinery 3 constituted by a lower cross member 30, an upper cross member 31 and side posts 32 connecting the lower cross member 30 to the upper cross member 31. This lower cross member 30 and these lateral posts 32 are made integral with the masonry of the building. This closure system 2 comprises, again, at least one opening (not shown) mounted movably (pivotally or slidingly) on the joinery 3, this between an open position and a closed position of the closure system 25 2. Said closure installation 1 further comprises a concealment system 4 fitted to such a closure system 2. Such a concealment system 4 adopts the form of a shutter comprising lateral slides (not shown) usually made integral with the lateral uprights 32 of the joinery 3 of the closure system 2. This concealment system 4 comprises, again, an apron (not shown) having lateral ends able to slide inside the lateral channels described herein. above, this between a deployed position at the front of the closure system 2 and a folded position above this closure system 2. This occultation system 4 comprises, also ent, a box 5 inside which is folded and from which is deployed the apron mentioned above. This box 5 then comprises, internally, a shaft for winding said deck in the folded position inside the box 5 and for the unwinding of the deck in the deployed position at the front of the closure system 2. 10 This box 5 is mounted on the joinery 3, more particularly by being attached to the joinery 3, this above the top rail 31 of this joinery 3 on which 31 is then mounted the box 5. In addition, this box 5 is fixed on this carpentry 3, more particularly on said upper cross member 31. In this regard, it will be observed that this box 5 comprises, then usually, an underside 50 and that it is, more particularly, this underside 50 which is mounted on the joinery 3 (more particularly being reported above 20 of the upper rail 31 of this woodwork 3) and which is fixed on this joinery 3 (more particularly on said upper cross member 31). This box 5 also comprises, and laterally, parts 51 of box 5, each surmounting a lateral upright 32 of the joinery 3 of the closure system 2 (or reported and / or resting on such a lateral upright 32), such Lateral upright 32 then supporting such a portion 51 of box 5. In addition, such a portion 51 of box 5 is made integral (more particularly by fixing) the joinery 3 (more particularly 30 of a lateral amount 32 of this woodwork 3 ) which advantageously makes it possible to immobilize such a portion 51 of box 5 with respect to the joinery 3. It will also be observed that this portion 51 of box 5 is also made integral with the masonry, depending on the case, directly and / or indirectly (in particular by being secured to the joinery 3 as described above, this joinery 3 being, itself, secured to the masonry). Such a fastening advantageously makes it possible to immobilize such a portion 51 of box 5 with respect to the masonry. In fact, it will be observed that such a portion 51 of box 5 may, at least in part, be constituted by a bracket 52, laterally closing said box 5, and on which is rotatably mounted said winding shaft / unwinding of the deck . Finally, this box 5 may comprise a horizontal reinforcement 53 which is designed to reinforce the closure system 1 (more particularly the closure system 2) with respect to horizontal stresses (for example due to the wind, to an attempt The horizontal reinforcement 53 can be used on any type of closure system 1 but is more particularly adapted to equip a closure system 1 comprising a closure system 2 of large size. length. In fact, such a horizontal reinforcement 53 usually adopts the shape of a profile or a plate and / or is made of steel. This horizontal reinforcement 53 extends over at least part (even and preferably all) of the length of the box 5. This horizontal reinforcement 53 is made integral with the upper crossbar 31 of the joinery 3, more particularly 25 by screwing. As can be seen in FIG. 3, this horizontal reinforcement 53 is positioned over the underside 50 of the box 5, inside this box 5, and is fixed on the upper rail 31 of the joinery 3, this through In this connection, it will be observed that this upper cross-member 31 may have a vertical deflection, this being due to its own weight and / or vertical stresses exerted on this upper cross-member 31. In fact, when the closure device 1 (more particularly the box 5) comprises a horizontal reinforcement 53 as described above, such a vertical stress can then result from the weight exerted by this horizontal reinforcement 53, or even the deflection of this reinforcement horizontal 53 under its own weight. The invention thus relates to a device 6 for correcting the vertical deflection of such an upper cross member 31 of the joinery 3 of a closure system 2 associated with the masonry of a building. This device 6 comprises: - a vertical reinforcement 7, extending horizontally, intended to extend substantially parallel to the upper cross member 31 of the joinery 3 and to be immobilized (at least vertically) with respect to the carpentry 3, more particularly with respect to at least one side jamb 32 (preferably with respect to the two lateral uprights 32) of this joinery 3; At least one base 8 intended to cooperate with the upper rail 31 of the joinery 3; at least one adjusting means 9 for the vertical position of such a base 8 with respect to the vertical reinforcement 7. Such vertical reinforcement 7 comprises a horizontal bracket 70 with which the adjustment means or means 9 cooperate and intended to take support on at least one support 54 stationary relative to the joinery 3, more particularly with respect to at least one side post 32 of this joinery 3. In fact, such a vertical reinforcement 7 adopts at least in part the shape of a angle, a piece "U", a tube, a portion of tube, a piece in an arc (the radius of such an arc can then correspond substantially to that of the rolling shutter apron in folded position in the box 5) or other. As can be seen in the appended figures, such vertical reinforcement 7 has the shape of a "U" -shaped piece comprising two parallel wings (70, 71), one of which 70 constitutes the horizontal bracket 70 mentioned above. This "U" -shaped piece further comprises a bottom 72 connecting the two parallel flanges (70, 71), and adopting a profile in an arc whose radius corresponds substantially to that of the rolling shutter deck in the folded-in position. the casing 5. With regard to said base 8, it comprises at least one horizontal flange (80, 81) with which the 5 or the adjusting means 9 and / or intended to cooperate with the upper cross member 31 of the Carpentry 3. Thus, said base 8 may comprise a horizontal flange 80 with which the adjustment means or means 9 cooperate. As seen in the appended figures, this horizontal flange 80 extends parallel to the horizontal support 70 of the reinforcement vertical 7, more particularly above this horizontal console 70. Said base 8 may also include a horizontal flange 81 intended to cooperate with the upper cross member 31. According to a first embodiment (not shown felt), such a horizontal flange 81 is intended to cooperate directly with said upper crossbar 31 of the joinery 3, this being made integral with the upper cross member 31 (directly or through the underside 50 of the box 5), especially by screwing. However, it has been illustrated in the figures in the appendix, a closure installation 1 comprising a concealment system 4 incorporating a box 5 having a horizontal reinforcement 53 25 as described above and secured to the upper cross member 31 of the Carpentry 3. In such a case, the horizontal flange 81 that comprises said base 8 is intended to cooperate with said upper cross member 31, this indirectly and through said horizontal reinforcement 53, more particularly coming to hang on. under a hooking flange that includes the horizontal reinforcement 53. In fact and as shown in the accompanying figures, said base 8 may be constituted by a jumper in "U" or 35 by a profile in "U" with two wings parallel (80, 81), connected by a bottom 82, and one 80 cooperates with the adjustment means 9 and the other 81 is intended to cooperate (directly or indirectly) with said trough It will be observed that said wings (80, 81) and, where appropriate, the "U" profile extend horizontally and parallel to the vertical reinforcement 7. As mentioned above, the device 6 The correction means comprises, also, at least one adjustment means 9. This or these adjustment means 9 may each be constituted by a screw, in particular a traction or compression screw, which cooperates with the base 8 as well as with the vertical reinforcement 7. In fact and as shown in the figures in the appendix, such adjustment means 9 is interposed between the base 8 and the vertical reinforcement 7, more particularly between the horizontal flange 80 of the base 8 and the horizontal bracket 70 of the vertical reinforcement 7. Also and according to a preferred embodiment of the invention illustrated in the appended figures, the horizontal flange 80 of the base 8 extends parallel to and above 20 of the horizontal console 70 of the vertical reinforcement 7 and is crossed by the or the screws of the adjustment means 9, such a screw bearing on the horizontal bracket 70 of this vertical reinforcement 7. The present invention also relates to a casing 5 of shutter that includes the occultation system 4 of a closure installation 1. This box 5 has the characteristics described above. In particular and as mentioned above, this box 5 is intended to be mounted and fixed on the upper cross member 31 of the joinery 3 of a closure system 2 constituted by a door, a window or the like. According to the invention, this box 5 comprises a device 6 for correcting the vertical deflection of the upper rail 31 of the joinery 3, this device 6 having, then, the features described above.

As mentioned above, this box 5 comprises, laterally, parts 51 of box 5 which are, each at least in part, constituted by a side bracket 52. In addition, each of these parts 51 of box 5 is 5 intended to be supported by a lateral amount 32 of the joinery 3 and each of these parts 51 of box 5 comprises means 55 for receiving the vertical reinforcement 7. In fact, these means 55 for receiving the vertical reinforcement 7 comprise a support 54 on which supports the vertical reinforcement 7 and / or a means 56 for immobilizing this vertical reinforcement 7 with respect to the casing 5. Thus, the means 55 for receiving the vertical reinforcement 7 comprise a support 54 on which the vertical reinforcement 7 bears. In fact and as visible in FIGS. 1 and 2, it is the lateral end of this vertical reinforcement 7, and more particularly the lateral end of the horizontal bracket 70 of this vertical reinforcement 7, which is supported on a such suppo 54. In this connection, it will be observed that, since it is a side jamb 32 of the joinery 3 which supports the part 51 of box 5 comprising such a support 54, the vertical reinforcement 7, based on such a support support 54, is then advantageously supported by such a lateral amount 32 of the joinery 3. It will be observed, also, that the support of the vertical reinforcement 7 on the support 54 advantageously allows to immobilize vertically this vertical reinforcement 7 relative to the portion 51 of box 5 which includes the support 54 and, therefore, with respect to the box 5 itself. As mentioned above, such a part 51 of box is made integral with the joinery 3 (more particularly of a lateral amount 32 of this joinery 3) which advantageously allows to immobilize, compared to the carpentry 3 (more particularly with respect to a lateral amount 32 of this joinery 3), such a portion 51 of box 5 but also such a support 54 which is, then, also immobile with respect to the joinery 3 (more particularly with respect to a lateral amount 32 of this joinery 3). It follows that, by resting on such a support 54, the vertical reinforcement 7 is, then, also immobile vertically with respect to the joinery 3 (more particularly with respect to a lateral amount 32 of this joinery 3) As mentioned here. above, the means 55 for receiving the vertical reinforcement 7 comprise means 56 for immobilizing this vertical reinforcement 7 with respect to the casing 5.

In this respect, it will be observed that this means for immobilizing 56 is, more particularly, designed to immobilize horizontally this vertical reinforcement 7 with respect to the box 5, but then also with respect to the joinery 3 as well as with respect to the masonry.

In fact, such a means for immobilizing 56 is constituted by a clamp, extending internally to the box 5, equipping a cooperating with the reinforcement with a lateral side of the bracket 52 of this box 5, and vertical 7, more particularly vertical reinforcement 7.

As mentioned above, the box 5 (more particularly its underside 50) is intended to be secured to the upper rail 31 of the woodwork 3. It is also with this upper rail 31 of 3 woodwork are intended to cooperate (directly or indirectly) or the bases 8 of the device 6 for correcting the deflection of this upper crossbar 31. In fact, such a base 8 can cooperate directly with this upper crossbar 31, this being made integral of the latter, in particular by screwing (solution not shown).

However, such a base 8 can, again, cooperate with this upper cross member 31 indirectly. This is, more particularly, the case when the box 5 comprises a horizontal reinforcement 53 intended to be secured to the upper crosspiece 31, in particular by screwing.

In such a case, or the bases 8 cooperate with this horizontal reinforcement 53, more particularly by attachment of a wing 81 of this base 8 under a hooking flange that includes the horizontal reinforcement 53. Finally, the invention concerns a closure installation 1 of an opening that presents the masonry of a building. Such a closure installation 1 has the characteristics mentioned above. In particular, such an installation 1 comprises, on the one hand, a closure system 2 in the form of a door, window or the like and incorporating a joinery 3 with at least 10 lateral uprights 32 and an upper crossbar 31 and, d on the other hand, a concealment system 4 incorporating a roller shutter box 5 mounted and fixed on the upper rail 31 of the joinery 3 of the closure system 2. According to the invention, the shutter box 5 of this installation closure 1 has the features described above. In particular, this closure installation 1 comprises a box 5 which comprises, laterally, parts 51 of box 5 (more particularly side brackets 52) 20 each supported by a lateral amount 32 of the joinery 3, and each having means 55 to receive the vertical reinforcement 7. In this installation 1, such a portion 51 of box 5 comprises, then and as it emerges from the foregoing, a support 54, supported by a lateral amount 32 of the joinery 3, and still (more particularly vertically) with respect to this joinery 3 (more particularly with respect to a lateral amount 32 of this joinery 3). This closure device 1 then also comprises a device 6 for correcting the deflection of the upper cross member 31 of the joinery 3 of its closure system 2. In particular, this installation 1 comprises such a device 6 comprising a reinforcement vertical 7, bearing on the support 54, supported by at least one side jamb 32 of the joinery 3, and stationary (more particularly vertically) with respect to this joinery 3 (more particularly with respect to at least one lateral upright 32 of this joinery 3).
