Description

The invention relates to a box extension device of roller shutter for receiving a concealment device and / or additional protection, such as a blind, mosquito net or the like. The invention further relates to a component rolling with such an extension device.

The present invention relates to the field of protection and occultation, such as blinds, mosquito nets, rolling shutters or the like.

It is more and more common to equip a window of means protection or partial occultation, such as a blind, to protect a home from the shelves solar panels, or a mosquito net so as to avoid entry flying insects, this in duplicate means of closure more hermetic, roller shutter type.

In this respect, some difficulties arise when it is wished to add such a device for occultation and / or additional protection for roller blinds, known as renovation, planned to be reported, from the outside, in the frame of a door or window.

Obviously, the casing of such a shutter can be pre-sized to accommodate, not only, the apron wrapped around its winding axis, but also this store or this additional mosquito net, as well as its mechanism drive.

Note, in this regard, that this implantation in the box is thus determined so that this blind or this mosquito net can unfold parallel and at the back of the shutter apron rolling, either between this apron and the door or window.

However, it should be noted that under these conditions of renovation, the rolling shutter box adopts a in which he is prominent externally, partly superior of a door or window. Therefore, for questions of aesthetics and thickness of the splaying in which must take position said rolling shutter, it is desirable to have a box that is as small as possible. This renovation roller shutter box is, so usually, strictly adapted to accommodate, in position folded, the apron of this shutter rolling and it is in the impossibility of receiving any mechanism winding additional blinds.

In fact, the addition of such a blind or mosquito net is done at through an independent set comprising a safe adapted to this blind and incorporating, therefore, the winding means of the last. This box overcomes, very often, backstage more particularly intended to guide the blind laterally or the mosquito net.

Thus, in a typical type of renovation, this box of the awning is interposed, externally, between the sleeping frame of the door or window and the shutter box.

In the end, in view of the foregoing, one understands that there is no simple solution for the time being allow, in case of renovation, to double or not a component rolling of a blind, a mosquito net or other, while having, in all cases, a box with dimensions systematically optimized to the chosen choice.

Finally, the present invention is able to respond to this problem through a box extension device of rolling shutter which, by simple substitution to the wall of this box lying substantially in the extension of guides of the deck, allows to enlarge this box of sufficient to be able to implement the mechanism winding a blind, a mosquito net or the like. Thus, this blind or this mosquito net can be guided laterally by scenes that are interposed between those of the apron of said roller shutter and the amounts of the sleeping frame of the door or window that comes to equip this last one.

In particular, the invention relates to a device for roller shutter box extension for the reception of a device for concealment and / or additional protection, such blind, a mosquito net or the like, characterized in that it has a front vertical wall adjusted to the length said box and walls of superior and lateral sections intended to cooperate, by means of appropriate connection, with the top wall and the flanges side of said shutter box.

This extension device, according to the invention, can still be consisting of the only upper extension walls and provided for, on the one hand, to cooperate through appropriate means of connection, with the upper wall and the lateral flanges of the casing of a rolling shutter, on these walls of upper and lateral extension still being to be reported the front wall of said box.

According to a first embodiment of the invention, this extension device defines means for receiving the winding mechanism of said occultation device and / or protection.

According to another embodiment, the extension device defines, in addition to the shutter box, the means receiving the winding mechanism of said device occultation and / or protection.

According to another particularity of the invention, the means of connection with the upper wall and the side flanges of the caisson are defined by complementary fastening means the attachment means equipping, on the edge, this wall upper and side flanges.

The advantages of the present invention are that the size of a shutter box can be easily adapted to whether or not to integrate a device occultation and / or additional protection, such as a blind, a mosquito net or other.

In short, for the manufacturer it is enough for him to manage the manufacture and keep in stock, on the one hand, caissons standard shutters and, on the other hand, extenders adapted to these standard boxes for, where appropriate, configure them so that they are able to receive this occultation and / or protection device additional.

The invention is explained in more detail in the description which will follow pertaining to embodiments given to as examples and illustrated in the figures of the attached drawing.

FIG. 1 is a schematic representation, in perspective and in section of an example of roller shutter box.

FIG. 2 is a schematic and sectional representation similar to Figure 1, illustrating this roller shutter box equipped with the extension device according to the invention.

Figure 3 is a side view and slightly in perspective of this roller shutter box equipped with the extension device according to the invention.

As shown in the figures of the attached drawing, the The present invention relates to the field of shutters and particularly relates to a device 1 for lengthening a box 2 of such a shutter 3, more particularly suitable for renovation.

In this respect, this roller shutter box 2 comprises, as visible in FIG. 1, an upper wall 4 and a wall vertical 5, immediately juxtaposed with the deployment plan of the apron (not shown) of the shutter 3, this wall vertical 5 being called front wall in the continuation of the description.

It includes, again, an underside 6 delimiting, in particular with the front wall 5, a slot 7 for passage of said apron, and a rear wall 8 or inspection hatch. Indeed, in the where in case of renovation the front wall 5 of this box 2 shutter 3 is intended to come in applied externally on the carpentry, such as a door, window or similar, access to the winding mechanism 9 of the deck does not can intervene only through this rear wall 8 provided removable for this purpose.

The casing 2 is again closed at its lateral ends 10 by lateral flanges 11 which, in certain configurations, can play the role of support cheeks, in that they are designed to support, directly, the tree winding of the rolling shutter apron.

It will be noted that the above description is intended to present the general characteristics of a shutter box rolling, knowing that there are different embodiments. AT As an example, shown in Figure 1, the different walls composing this box 2 are not necessarily independent of each other. In particular the underside 6 can be directly integral with the wall rear 8, as the upper wall 4 and the front wall 5 can be defined by an angled profile.

In addition, the connection between these different walls can be ensured by interlocking thanks to fastening means 12 that has one of these 4 walls and is designed to cooperate with complementary attachment means 13 of which is equipped the other wall 5.

One can still imagine bonds made by riveting, screwing or similar means.

To return to the extension device 1, it comprises a front vertical wall 5A adjusted at least in length to that of the box 2 of the shutter 3 and the walls of upper extension 4A and lateral 11A provided suitable for cooperate, through appropriate means of connection 14, with the upper wall 4 and side flanges 11 of said housing 2.

In particular, in case it is necessary to extend the box 2 of a shutter 3 to incorporate a device occultation and / or additional protection, store type, mosquito net or similar, it is removed its front wall 5 that can, if necessary, recover to define the wall before 5A of said extension device 1. Also, by extension, the extension device 1 may consist of only upper extension walls 4A and side walls 11A intended, on the one hand, to cooperate through said means 16, with the upper wall 4 and the flanges 11 of the casement 2 of a roller shutter 3, on these walls of upper extension 4A and lateral 11A still planned able to be reported said front wall 5 of the box 2.

Moreover, if the attachment means 12 that the upper wall 4 and, if appropriate, lateral flanges 11 of this box 2 are of adapted design, they can define, in part, the connecting means 14 which are then supplemented by complementary attachment means (not shown) that have the upper 4A and lateral extension walls 11A of the extension device 1.

In the case where said attachment means 12 have a shape adapted, it can be made a cut at the wall upper 4 and if necessary at the side flanges 11 of the box 2 which have a right edge with which are able to cooperate with nesting means 16 that have, then, on their song 17 the walls of extension superior 4A and lateral 11A for the definition of the means of link 14.

As an example shown in the attached drawing, such nesting means 16 may take the form of a step 18 at the edge 19 of these extension walls upper 4A and lateral 11A so as to enable them to extend, in part, under the upper wall 4 and the flanges 11 of the box 2. Riveting, welding, screwing and / or gluing ensures, in the end, a rigid connection of the extension device 1 to this housing 2.

As a means of nesting 16, the edge 17 of the walls of extension 4A and 11A may have a "U" shape their allowing to engage on the end edge 15 of the wall upper 4 and lateral flanges 11 of the casing 2.

According to the invention, this extension device 1 can define in means for receiving the concealment device and / or additional protection and have, internally, 20 adapted for mounting its winding mechanism.

In particular, as shown in FIG. 2, such means 20 can be in the form of tips for receiving pivotally of the winding shaft 21 of such occultation and / or protection device. More simple, these means 20 can be defined by openings for the passage of any fasteners and / or forming bearing for receiving axle sections on which is pivotably mounted on said winding shaft 21.

Since it usually persists in box 2 an available space in the upper corner 22 located, substantially, in the vertical extension of the wings 23 of lateral guidance of the roll shutter apron 3, the means of reception of the concealment and / or protection device may be defined, substantially, in part by the casing 2 and the extension device 1. From this way one comes to optimize the final size of this box 2.

So, in this configuration and in case of renovation, this additional store or mosquito net is perfectly capable of deploy at the back of the shutter apron, either between last and the door or window against which is applied, externally, said shutter 3.

Note that for this deployment, this store or this mosquito net can be guided laterally by means of wings 24 adapted between the door or window and the slides 23 for guiding the shutter apron, as visible in Figure 2. He was again represented in the FIG. 3 is a double slide 23A that replaces the slide 23 to guide both the apron and the additional store.

The present invention, therefore, responds advantageous, the problem posed.
