Description

The invention relates to a box extension device

  roller shutter for the reception of an additional occultation and / or protection device, such as a blind, a mosquito net or the like. The invention also relates to a roller shutter comprising such an extension device.

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

  It is more and more common to equip a window with 10 means of protection or partial occultation, such as a blind, to protect a house from the sun's rays, or a mosquito net so as to avoid the entrance of flying insects, this in doublon more hermetic means of closure, type roller shutter.

  In this regard, some difficulties arise when it is desired to add such a device for occultation and / or additional protection to shutters, called renovation, provided to be reported from the outside, in the frame of a door or window.

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

  Note, in this regard, that this implantation in the box is thus determined so that the blind or the mosquito net can be deployed parallel to and behind the apron of the shutter, or between the apron and the door or window.

  However, it should be noted that under these conditions of renovation, the casing of the shutter adopts a provision in which it is prominent externally, in the upper part of a door or window. Therefore, for aesthetic reasons and the thickness of the splaying in which said shutter must take position, it is desirable to have a box that is as small as possible. This box rolling shutter renovation is, therefore usually strictly adapted to accommodate, in the folded position, the apron of the shutter and it is impossible to receive any winding mechanism of additional blinds.

  In fact, the addition of such a blind or mosquito net is through an independent assembly comprising a chest adapted to this blind and incorporating, therefore, the winding means of the latter. This box very often overcomes slides specifically designed to guide laterally the blind or the mosquito net.

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

  In the end, in view of the foregoing, it is well understood that there is no simple solution for the time being, which, in the event of renovation, will make it possible to double a roller shutter or not. a blind, a mosquito net or other, while having, in all cases, a box with dimensions 20 systematically optimized choice chosen.

  Finally, the present invention is able to respond to this problem through a roller shutter box extension device which, by simple substitution to the wall of this box being located substantially in the extension of the guide rails of the apron, allows to enlarge this box sufficiently to be able to implement the winding mechanism of a blind, a mosquito net or similar. Thus, this blind or this mosquito net can be guided laterally by slides 30 interposed between those of the deck of said shutter and the amounts of the frame of the door or window that comes to equip the latter.

  In particular, the invention relates to a roller shutter box extension device for receiving an additional concealment and / or protection device, such as a blind, a mosquito net or the like, characterized in that it comprises a front vertical wall fitted to the length of said box and upper and lateral extension walls provided adapted to cooperate, through appropriate connecting means, with the upper wall and the side flanges of said shutter box.

  This extension device, according to the invention, may also consist of only the upper and lateral extension walls provided adapted, on the one hand, to cooperate through appropriate connecting means, with the upper wall and the side flanges of the casing of a shutter, on these upper and lateral extension walls being still able 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 concealment and / or protection device.

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

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

  The advantages of the present invention are that the dimension of a shutter box can be easily adapted to the fact that it must or not incorporate an additional occulting and / or protection device, such as a blind. , mosquito net or other.

  In short, for the manufacturer it suffices to manage the manufacture and keep in stock, on the one hand, standard roller shutter boxes and, on the other hand, extension devices adapted to these standard boxes for, the case If necessary, configure them so that they are able to receive this additional concealment and / or protection device.

  Other objects and advantages of the present invention will become apparent from the following description relating to an exemplary embodiment given by way of indication and not limitation.

  The understanding of this description will be facilitated with reference to the drawing, attached, in which: - Figure i is a schematic representation, in perspective and in section of an example of roller shutter box; - Figure 2 is a schematic representation and in section 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 the roller shutter box equipped with the extension device according to the invention.

  As shown in the figures of the attached drawing, the present invention relates to the field of roller shutters and relates, in particular, to a device i for extending a box 2 of such a shutter 3, more particularly adapted to the renovation.

  In this regard, this casing 2 shutter comprises, as shown in Figure 1, an upper wall 4 and a vertical wall 5, immediately juxtaposed to the deployment plane of the deck (not shown) of the shutter 3, this vertical wall 5 being called front wall in the continuation of the

description.

  It comprises, 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, insofar as in case of renovation the front wall 5 of the casing 2 roller shutter 3 is intended to apply externally on the joinery, such as a door, window 35 or the like, access to the mechanism winding 9 apron can only intervene through this rear wall 8 provided removable for this purpose.

  The casing 2 is again closed at its lateral ends by lateral flanges 11 which, in certain configurations, can act as support cheeks, in that they are provided able to directly support the winding shaft. rolling shutter deck.

  It will be appreciated that the above description is intended to present the general characteristics of a rolling shutter box, knowing that there are different embodiments.

  By way of example, moreover represented in FIG. 1, the various walls making up this caisson 2 are not necessarily independent of one another. In particular, the underside 6 may be directly integral with the rear wall 8, just as the upper wall 4 and the front wall 5 may be defined by an angled profile.

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

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

  To return to the extension device 1, the latter 25 comprises a front vertical wall 5A adjusted at least in length to that of the box 2 of the shutter 3 and the upper extension walls 4A and 11A provided lateral adapted to cooperate, through appropriate connecting means 14, with the upper wall 4 and the lateral flanges 11 of said box 2.

  In particular, in the case it is necessary to extend the casing 2 of a shutter 3 to incorporate an additional blocking device and / or protection, type store, mosquito net or similar, it is removed its front wall 5 35 that it can, if necessary, recover to define the vertical wall before 5A of said extension device 1. Also, by extension, the extension device 1 may be constituted only of the upper extension walls 4A and 11A provided suitable side walls, on the one hand, to cooperate through said connecting means 16, with the upper wall 4 and the side flanges 11 of the casing 2 of a roller shutter 3, on these upper extension walls 4A and lateral walls 11A being still provided for in FIG. even to be reported said front wall 5 of the box 2.

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

  In the case where said attachment means 12 have an unsuitable shape, a cut-out can be made at the level of the upper wall 4 and, if appropriate, at the level of the lateral flanges 11 of the casing 2 which have a right-hand edge 15 with which are able to cooperate interlocking means 16 that comprise, then, on their edge 17 the upper extension walls 4A and lateral 11A for the definition of the connecting means 14.

  By way of example shown in the accompanying drawing, such interlocking means 16 may take the form of a recess 18 at the edge 19 of these upper and laterally extending walls 4A and 11A so as to allow them to extend in part, under the upper wall 4 and the side flanges 11 of the box 2. A riveting, welding, screwing and / or gluing ensures, finally, a rigid connection of the extension device 1 to the box 2.

  As the interlocking means 16, the edge 17 of the extension walls 4A and 11A may have a U-shape enabling them to engage the end edge 15 of the upper wall 4 and the lateral flanges 11 of the box 2.

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

  In particular, as shown in FIG. 2, such means 20 may be in the form of end pieces for pivotally receiving the winding shaft 21 of such a concealment and / or protection device. More simply, these means 20 may be defined by openings for the passage of any fastening members and / or bearing for receiving axis sections on which is pivotally mounted said winding shaft 21.

  Insofar as, usually, there persists in the caisson 2 an available space in the upper angle 22 situated, substantially, in the vertical extension of the lateral guiding slide 23 of the rolling shutter apron 3, the means for receiving the device Additional concealment and / or protection can be defined, substantially in part, by the casing 2 and the extension device 1. In this way, the final size of this casing 2 is optimized.

  Thus, in this configuration and in case of renovation, this additional blind or mosquito net is perfectly able to deploy at the rear of the shutter apron, or between the latter and the door or window against which is applied, externally, said shutter 3.

  Note that for this deployment, this blind or this mosquito net can be guided laterally by means of adapted slides 24 which are interposed between the door or window and the slides 23 for the apron guidance of the roller shutter, as can be seen in FIG. It is also shown in FIG. 3 a double slide 23A replacing the slide 23 to guide both the apron and the additional blind.

  The present invention, therefore, responds advantageously to the problem.

  Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. 5 various elements without departing from the scope and spirit of the invention.
