Description

The present invention relates to a device for closing an opening that includes a building masonry.

This invention relates to the field of building construction, more particularly that of the manufacture of closing devices for an opening of a masonry of such a building, such a device comprising, on the one hand, a door, window or analogous carpentry is positioned at the front or inside of such an opening and, secondly, a roller shutter comprising a box surmonting said joinery.

First of all, it should be observed that, when such an opening is closed only by a door or the like (therefore in the absence of roller shutter), the joinery of such a door is secured to the masonry by through fasteners associated with the lateral uprights and the upper and lower rails. Such a fastening advantageously makes it possible to immobilize said door with respect to the masonry and to avoid that, under the effect of a constraint such as the wind, this door moves, deforms or even undergoes damage, more particularly under broken form of a glazed element.

However, when such a door or the like is completed by a roller shutter, the casing of such a shutter is attached over the top rail of the door carpentry which prevents the attachment of the upper rail on the masonry.

In this regard, it will be observed that the door or the like is usually designed and dimensioned to withstand stresses, particularly wind, without deformation, this when the joinery of such a door is secured to the masonry by its members. side uprights as well as through its upper and lower rails. In the absence of attachment of the top rail to the masonry, resistance to these constraints is considerably less exposing the door not only to a lack of sealing between the joinery and the box but also to the aforementioned degradation.

In addition, the manufacture of such a door is made in accordance with regulations and standards which impose the presence of acoustic and / or thermal insulation elements considerably reducing the possibilities of implantation of any reinforcing member to level of carpentry.

However, when the closure device comprises a roller shutter incorporating a box provided with an underside, on the one hand, at least partially closing the bottom of this box and, on the other hand, extending over carpentry of the door or the like, it is customary to fix such a soffit directly on this joinery.

When such an underside is formed or supplemented by a rigid element (more particularly a sheet metal plate or the like), the rigidity of this element allows, at least in part, to remedy the lack of rigidity of the joinery.

However, and in such a case, the fixing of the box on the joinery takes place by the interior of this box which, on the one hand, is a particularly difficult operation because of the difficulty of access and the smallness of the box and, on the other hand, requires a specific design of this box, more particularly in order to allow a setting up of a winding shaft of the rolling shutter apron inside the box after assembly of the latter on carpentry.

It is also known closure devices comprising a roller shutter incorporating a box (usually known as a half-chest box) consisting, on the one hand, by a front part of box extending over the joinery and having a vertical front wall and a lateral wing, horizontal, external to the box and by which this box is attached to the joinery and, secondly, a rear portion of the box, extending at least at the rear of carpentry (or even partly over the carpentry) and at least in the opening or in a reservation of masonry.

In fact, in such a case, most of the box extends to the rear of the joinery while only a small part of this box extends over the joinery. Such a box, either has no underside extending over the joinery, or has an underside extending over the joinery but too small to provide any stiffness, or is positioned relative to the joinery to carpentry in such a way that it is not possible to set up any reinforcement.

It is, again, known the document FR-2652380 relating to a roller shutter box and in which is described a closure device having the features of the preamble of claim 1.

We also know the document EP-1209316 relating to a trunk body for roller shutter.

The present invention is intended to overcome the disadvantages of closure devices of the state of the art.

• une menuiserie de porte, fenêtre ou analogue destinée à être positionnée à l'avant et/ou à l'intérieur de cette ouverture ;
• un volet roulant incluant un caisson de volet roulant comportant, d'une part, une partie avant de caisson s'étendant par-dessus la menuiserie, au moins en partie rapportée par-dessus cette menuiserie, et fixée sur une traverse supérieure de cette menuiserie et, d'autre part, une partie arrière de caisson, s'étendant au moins à l'arrière de la menuiserie, et destinée à venir se positionner au moins dans l'ouverture de la maçonnerie ou dans une réservation que comporte cette maçonnerie au-dessus de cette ouverture ;
• au moins un renfort pour renforcer la menuiserie et/ou le caisson et comportant au moins un profilé :

To this end, the invention relates to a closing device of an opening that includes a building masonry and which comprises at least.

• a door, window or the like carpentry intended to be positioned at the front and / or inside of this opening;
• a shutter including a roller shutter box comprising, on the one hand, a casing front portion extending over the joinery, at least partly attached over this joinery, and fixed on a top rail of this joinery and, secondly, a rear portion of the box, extending at least behind the joinery, and intended to be positioned at least in the opening of the masonry or in a reservation that includes the masonry at above this opening;
• at least one reinforcement for reinforcing the joinery and / or the box and comprising at least one profile:
• reported externally to the box and on the front part of this box;
• extending longitudinally with respect to the casing and at least over the top rail of the joinery, this over at least a portion of the length of the casing and / or of this top rail;
• fixed at least on the top rail of the joinery as well as on the front part of the box;
• and comprising, on the one hand, a first part coming into application against the front part of the roller shutter box and, on the other hand, a second part which is applied against the front part of the box and fixed on the upper cross member of the carpentry as well as on the front part of the box.

• une paroi avant s'étendant verticalement à partir de la menuiserie et contre laquelle vient en applique la première partie du profilé que comporte le renfort ;
• une aile latérale, d'une part, s'étendant perpendiculairement à partir de la paroi avant du caisson et parallèlement à la traverse supérieure de la menuiserie, d'autre part, rapportée sur cette traverse supérieure et par-dessus laquelle est rapportée en applique la deuxième partie du profilé que comporte le renfort et, d'autre part encore, traversée par un moyen pour la fixation de ce renfort sur cette traverse supérieure et sur la partie avant du caisson.

This closure device is characterized in that the front part of the shutter box comprises:

• a front wall extending vertically from the joinery and against which comes to apply the first part of the profile that includes the reinforcement;
• a side wing, on the one hand, extending perpendicularly from the front wall of the box and parallel to the upper cross member of the joinery, on the other hand, attached to the top rail and over which is applied the second part of the profile that includes the reinforcement and, secondly, crossed by a means for fixing this reinforcement on the upper rail and the front part of the box.

According to an additional feature, the reinforcement further comprises a tube positioned inside the profile and having a section and / or dimensions adjusted to those of the profile and / or allowing its positioning inside the profile by sliding.

Thus, the closure device according to the present invention comprises a reinforcement attached to the box, externally thereto, which advantageously allows this reinforcement to be put in place by the outside of the box, which on the other hand, is much easier than setting up the interior of such a box and, on the other hand, overcomes the disadvantages described above of such an implementation by the interior of the box.

The presence of such a reinforcement, outside the box, allows to reinforce this box and / or joinery without requiring the establishment of such a reinforcement inside the box, especially with the problems of accessibility or lack mentioned above.

The reinforcement comprises at least one profile, or even a tube positioned internally to said profile, which advantageously makes it possible to adapt this reinforcement (more particularly its rigidity) to the size (width) of the door, window or the like, this for to confer on such a door or the like the rigidity necessary to cope with external constraints.

The present invention relates to the field of building construction 1 and will find a particular application when it comes to closing an opening 10 that includes a masonry 11 of such a building 1.

The invention relates, then, more particularly to a device 2 for closing such an opening.

Such a closure device 2 comprises, on the one hand, a door 3, a window or the like constituted by a joinery 30 as well as by at least one opening (not shown), mounted on this joinery 30, and capable of adopting a open position and a closed position.

When the closure device 2 is installed at the level of the masonry 11 of the building 1, the joinery 30 of this door 3, window or the like is intended to be positioned, either at the front (according to an observer positioned at the interior of the building 1 and facing the closing device 2) the opening 10 of the masonry 11 and applied against this masonry 11 (as shown figure 3 ), either inside this opening 10, or partly at the front and partly inside such an opening 10.

This joinery 30 is then made integral with this masonry 11 by fixing, on this masonry 11, the lateral uprights 31 and the lower rail 32 of this joinery 30.

On the other hand, such a closure device 2 comprises a shutter 4 including a box 5 shutter, a winding shaft (positioned or intended to be positioned inside the box 5), an apron (connected said winding shaft and intended to be wrapped around this winding shaft and inside said box 5) as well as lateral slides (inside which scrolls the lateral ends of the deck and usually equipping the carpentry 30, this at the rear of the door 3, window or the like).

In fact, such a box 5 shutter 4 comprises, firstly, a front portion 50 of box 5 (according to an observer positioned inside the building 1 and facing the closure device 2), extending above the joinery 30 of the door 3 or the like, at least partially attached above this joinery 30, and fixed on an upper rail 33 of this joinery 30.

On the other hand, this box 5 shutter 4 comprises a rear portion 51 of box 5 (again according to an observer positioned inside the building 1 and facing the closure device 2), extending at least to the rear of the joinery 30, or even partly over this woodwork 30.

This rear portion 51 of box is intended to be positioned at least in the opening 10 of the masonry 11 or (and as shown figure 3 ) in a reservation 12 that includes the masonry 11 above this opening 10.

In this regard, it should be noted that the present invention can find an application for any type of shutter 4.

However, this invention will find a particularly suitable application when such a shutter 4 comprises a casing 5 roller shutter 4 usually called box half-chest as shown in the accompanying figures.

In fact and as visible on the figure 3 such a box 5 has a front portion 50, extending over the joinery 30 of the door 3 or the like, and having, on the one hand, a front wall 500 extending vertically and from the joinery 30 of the door 3 or the like, more particularly from the upper rail 33 of this joinery 30.

On the other hand, this front portion 50 has a lateral flange 501 extending horizontally, perpendicularly from the front wall 500 of the box 5, and parallel to the upper rail 33 of the joinery 30.

It is, more particularly, this lateral wing 501 which is attached to this upper rail 33 of the joinery 30 and which is secured to this upper crossbar 33.

As visible on this same figure 3 such a box 5 has a rear portion 51 extending to the rear of the joinery 30 and partly over this joinery 30.

Such a rear portion 51 has an upper wall 510 (more particularly secured to the front wall 500 of the front portion 50 of the casing 5, in particular by clipping), a rear wall 511 and an underside 512 extending under the box 5 and closing the latter 5 in part, so as to allow the passage of the deck between the underside and the joinery 30.

It will be observed that the upper wall 510 and the rear part 511 (or even the underside 512) may be constituted by a single element, more particularly in the form of a cover, made integral with the front wall 500 of the front part 50 of the box 5, in particular by clipping.

The closure device 2 comprises, again, at least one reinforcement 6 designed to reinforce the joinery 30 and / or the box 5.

• rapporté extérieurement au caisson 5 et sur la partie avant 50 de ce caisson 5 (plus particulièrement sur la paroi avant 500 ainsi que sur l'aile latérale 501 de cette partie avant 50 de caisson 5);
• s'étendant de manière longitudinale par rapport au caisson 5 et au moins par-dessus la traverse supérieure 33 de la menuiserie 30, ceci sur une partie au moins de la longueur du caisson 5 et/ou de cette traverse supérieure 33 (plus particulièrement sur l'intégralité de la longueur de cette traverse 33 comme visible figures 1 et 2);
• fixé au moins sur la traverse supérieure 33 de la menuiserie 30 ainsi que sur la partie avant 50 du caisson 5 (plus particulièrement sur l'aile latérale 501 que comporte cette partie avant 50 du caisson 5).

According to the invention, this reinforcement 6 comprises at least one profile 60:

• reported externally to the box 5 and on the front portion 50 of the box 5 (more particularly on the front wall 500 and on the lateral flange 501 of the front portion 50 of box 5);
• extending longitudinally with respect to the box 5 and at least over the top rail 33 of the joinery 30, this over at least a portion of the length of the box 5 and / or of this upper rail 33 (more particularly on the entire length of this crossbar 33 as visible Figures 1 and 2 );
• fixed at least on the top rail 33 of the joinery 30 and on the front portion 50 of the box 5 (more particularly on the lateral flange 501 that includes the front portion 50 of the box 5).

In fact and according to the invention, such a section 60 comprises, on the one hand, a first portion 600 coming into application against the front portion 50 of the casement 5 shutter 4, more particularly against the front wall 500 that includes this part before 50 of the box 5.

On the other hand, this profile 60 includes a second portion 600 'also applying against the front portion 50 of the box 5, more particularly against the lateral flange 501 that includes the front portion 50 of the box 5.

This second portion 600 'of profile 60 extends over the top rail 33 of the joinery 30 as well as over said lateral wing 501 of the front portion 50 of the box 5, this lateral wing 501 being, then and as such visible Figures 1 to 5 interposed between the second portion 600 'of this section 6 and this upper cross member 33.

This second part 600 'of section 60 is, again, fixed on the top rail 33 of the joinery 30 as well as on the front portion 50 of the box 5, more particularly on the lateral flange 501 of this front portion 50 of box 5.

In this regard, it will be observed that it is, more particularly, through the attachment of this second portion 600 'of profile 60 on the upper cross member 33 that said lateral flange 501 (and, therefore, the front portion 50 of the box 5 and, therefore, the box 5 itself) is attached to the joinery 30 of the door 3 or the like.

According to a first embodiment, the profile 60 comprising said first 600 and said second 600 'part may be constituted by a tube whose first 600 and / or second portion 600' take the form of a involute of a circle, in particular of different radius.

Another embodiment consists in that the profile 60 is constituted by a circular or elliptical section tube. The first 600 and the second portion 600 'of profile 60 of such a tube may then also have a different radius.

Such a tube comprises, then and preferably, a longitudinal opening allowing, advantageously, the establishment, inside the profile 60 and through this opening, a fastener of this profile 60 on the joinery 30 .

However, according to a preferred embodiment of the invention, the first 600 and the second 600 'part of the profile 60 each comprise at least one wing (601, 601 '), these two wings (601; 601'), on the one hand, being in the extension one (601 '; 601) of the other (601; 601 ') and, on the other hand, extending (601'; 601) from the other (601; 601 ') substantially perpendicularly.

A particular embodiment then consists in that such a profile 60 takes the form of an angle iron or the like.

Another feature of such a profile 60 is that the two parts (600; 600 ') have, perpendicular to the general direction of extension of the profile 60, a different width.

Such an embodiment advantageously makes it possible to position this profile 60 in one direction (the second part 600 'of profile 60 having the greatest width and coming into application on the lateral flange 501 as illustrated Figures 1 to 4 ) or in the other (the second portion 600 'of profile 60 having the smallest width and applying to the side flange 501 as illustrated figure 5 ), so as to adapt to the thickness of a means 7 of insulation and / or doubling reported on the masonry 11.

Another feature of the invention is that the first 600 and / or the second 600 'part of the profile 60 are provided with at least one hole 602, more particularly a pre-drilling.

Such a bore 602 is intended to receive a means for fixing this profile 60 at least on the upper rail 33 of the joinery 30.

In fact, such a fixing means is constituted by a screw (more particularly a self-drilling screw) engaged inside such a bore 602, passing through the lateral flange 501 of the front portion 50 of box 5 and screwed in the upper cross member 33 (more particularly in a metal section that internally comprises such an upper cross member 33) of the joinery 30.

Yet another feature of the invention is that the profile 60 has at least one return (603; 603 '), on the one hand, extending from the end of the first 600 and / or the second 600 'part of the profile 60, parallel to the second 600' and / or the first 600 part of the profile 60 and in the same direction as the second 600 'and / or that first 600 part of the profile 60.

When such a return 603 equips the first portion 600 of the profile 60, this return 603 delimits a longitudinal opening 603, as the case may be, with the second 600 'profile portion 60 or with another return 603' extending from the end of this second portion 600 'of section 60, parallel to the first 600 part of the profile 60 and in the same direction as the first 600 part of the profile 60.

However, when such a return 603 'equips the second part 600' of the profile 60, this return 603 'delimits a longitudinal opening 603, as the case may be, with the first 600 profile part 60 or with another return 603 extending , from the end of this first portion 600 of section 60, parallel to the second portion 600 'of profile 60 and in the same direction as this second portion 600' of section 60.

As can be seen in the appended figures, the profile 60 having the characteristics described above substantially adopts a "C" section.

In fact, a profile 60, having the characteristics described above, has sufficient rigidity to properly reinforce the joinery 30 and / or the box 5 of a closure device 2 of a door 3 or a small window width or average width.

However, and in the context of a door 3 or of a window of medium width or of large width, a reinforcement 6 constituted solely by such a section 60 may be insufficient to reinforce the joinery 30 and / or the casing 5 of appropriate way.

Such a reinforcement 6 comprises, then again, a tube 61, positioned inside the aforementioned section 60, and having a section and / or dimensions adjusted to those of this section 60 and / or allowing its positioning inside the profile 60 by sliding.

• on rapporte, tout d'abord, le profilé 60 sur la partie avant 50 de ce caisson 5 ;
• on engage, au travers de l'ouverture longitudinale 604 du profilé 60 et à l'intérieur de ce profilé 60, au moins un organe de fixation que l'on introduit dans un perçage 602 ;
• on fixe, ensuite et avec cet organe de fixation, ce profilé 60 sur la traverse supérieure 33 de la menuiserie 30, ceci au travers de l'aile latérale 501 de la partie avant 50 du caisson 5 ;
• on engage le tube 61 à l'intérieur du profilé 60, ceci de manière latérale par rapport à celui-ci 60.

In this respect, it will be observed that, when placing such a reinforcement 6 on the casing 5:

• firstly, the profile 60 is reported on the front portion 50 of this box 5;
• is engaged, through the longitudinal opening 604 of the profile 60 and within this profile 60, at least one fastener which is introduced into a bore 602;
• this profile 60 is then fixed and with this fastener on the top rail 33 of the joinery 30, this through the lateral flange 501 of the front portion 50 of the box 5;
• the tube 61 is engaged inside the profile 60, this laterally with respect thereto 60.

According to a first embodiment, this tube 61 is immobilized inside the profile 60 under the effect of a section and / or a dimension of this tube 61 adjusted, particularly tightly, to those of this profile 60.

However, according to another characteristic, at least one return (603; 603 ') that includes the profile 60 is provided with at least one hole 605, more particularly a pre-drilling, intended to receive a fixing screw of this profile 60 on the tube 61.

Such an embodiment advantageously makes it possible, on the one hand, to make a hole 605 only in the or the returns (603; 603 ') of the profile 60 and, on the other hand, to engage and guide a screw ( preferably of the self-drilling type) in such a bore 605 (by preventing such a screw from flushing with respect to the profile 60 during its screwing) and, secondly, by screwing such a screw into the tube 61 in such a way that easy.

Finally, this section 60, or even the tube 61, are made of a metal material (in particular steel, aluminum or other) and / or composite (including charged type, multilayer or other).
