Description

Support device for a tree winding of a closing or sun protection installation and corresponding installation.

The present invention relates to a support device of a winding shaft of a installation of closure or sun protection, as well as a closing or sun protection installation provided with less a support device.

By closing installation, the doors, portals, blinds and other elements equivalent.

The invention more particularly provides a installation of closure or sun protection, of the aforementioned type previously, which is provided with a screen whose tree winding is received in a chest. In this regard, it is due note that the invention finds its application for any type of winding shaft, whatever the maneuver mode of the latter, namely motor, lathe and crank, or even belt.

The placement is already known, in the vicinity of the side faces of the chest, of a support device, intended to receive a corresponding end of the tree from winding In this regard, the document US-A-4,234,032 teaches to provide each face using a pin, appropriate to receive this device from support.

A support device is also known, marketed by the company ASA with the reference 2203045, which It is represented in the attached figure 7. This device 312, which collects the set of features of the preamble of the attached claim 1, first comprises an element of reception 314 of the aforementioned end of the tree winding, which is drilled by a central hole 316_2 of step of the busty face. This receiving item 314 presents a globally symmetrical rectangular shape with respect to the center of this hole.

The support device also comprises a immobilization element 320, substantially U-shaped. service, the soul 322 of this element 320 rests against the peripheral walls of the chest, while its 324 wings rest against the side walls facing the receiving element 314, to prevent rotation of the latter.

This support device of the ASA company It has a remarkable interest, particularly because it allows to avoid any perforation or any screwed on the face of the chest. Therefore, this gives an advantageous aesthetic to the closing or sun protection installation of which it is equipped

The inconvenience related to this support device resides anyway in its lack of polyvalence.

In effect, the length of a closing screen or sunscreen is variable, depending on the dimensions of the area to cover. In particular, if it is a closing screen, thickness and pitch of the constituent sheet of This may vary substantially.

It follows that the diameter of this screen, once wound, is capable of presenting very different dimensions from one installation to another. In this regard, it is usual for manufacturers to propose in general at least two chests of appropriate sections, in order to meet these requirements. On the other hand, since the dimensions of each chest vary from one manufacturer to another, there is a vast decline in sections of
chests

Now, the material proposed by the ASA company does not allow to satisfactorily cover the whole of these sections. Therefore, it is necessary to have several different supports, of which each one is adapted to a corresponding chest dimension. Therefore, it is conceived that this situation involves significant costs, particularly in terms of storage and the number of commercial references.

On the other hand it is known, from the document EP-A-0 784 145, a rolling shutter comprising a curtain, a tree, as well as a means of holding said tree, which in particular comprise a console, which is screwed on the face of the chest. This known solution it has been, however, less comfortable than the device ASA company support, described above, particularly in the extent to which a screwed is involved.

Having said that point, the invention is proposed avoid all the disadvantages of the prior art that They have been stated above.

To this end, the invention aims at a support device according to claim 1 attached.

The advantageous features of the invention they are the subject of subordinate claims 2 a 10.

The object of the invention is also a closure or sun protection installation according to claim 11 attached.

The invention and its advantages will become more clearly apparent from the following description of three embodiments of a support device according with its principle, given only as examples not limiting and referring to the attached figures, in the that:

- Figure 1 is a perspective view exploded, which partially illustrates a closing installation  or sunscreen according to the invention;

The closing or sun protection installation, partially represented in figure 1, it comprises a tree 2, commanded by an electric motor 4. A closing board, not represented, it is appropriate to be wrapped around the tree above.

This tree is received in a chest, or drawer 6, which has peripheral walls 8, as well as two walls lateral, which are formed by faces, of which only one 10 is represented in figure 1. The different organs mechanics mentioned above are of the classic type, such so that they are described succinctly.

The installation also includes a device of support of the winding shaft 2, which is designated in its set with numerical reference 12.

As Figure 2 shows in particular, this device comprises a first element 14, also called receiving element, which globally presents a U-shape. Thus, it presents a soul 16, which comprises a central part 16_ {1}, in which has been made a hole 16_ {2} for receiving a busty 10_ {1}, which extends from the facing face 10. This hole 16_ {2} thus allows to immobilize radially the receiving element 14 with respect to said face 10.

The soul 16 also has two walls lateral 16_ {3}, which form protrusion with respect to the part central 16_ {1} in the direction of the engine, namely in opposition to the face 10. This soul thus forms, in a known way, an area of reception of the corresponding end of the motor 4. A reception of this type can be secured, for example, by screwing the motor in the central part 16_ {1} and / or by interlocking said motor at the side walls 16_ {3}.

The receiving element 14 is provided by another part of two wings 18, which extend from the walls lateral 16_ {3} of the soul 16.

The support device 12 further comprises of the receiving element 14, an immobilization element 20, also in a U-shape. The soul 22 of said device is appropriate to rest against one of the peripheral walls 8 of the drawer 6, while its wings 24 are appropriate to prevent pivoting of the receiving element 14, as will be seen in the continuation of the description.

Finally, some means are planned that allow the reception element 14 and the immobilization element 20, while ensuring a radial displacement between these two elements. To this end, the two wings 24 of the immobilization element 20 are perforated by respective oblong holes 24_ {2}, while a screw 26 is integral with the two wings 18 of the element of reception 14. Therefore, it is conceived that it is possible to do slide these two elements 14 and 20 with respect to each other, in this example according to a vertical direction in figures 3 and 4, and keep them in position by screwing the screws 26 against the walls of the oblong holes 24_ {2}.

The center of hole 16_ {2} is noted as C, practiced in the soul 16. Therefore, it is conceived that, contrary to the prior art, the receiving element 14 it is not symmetric, in the plane of hole 16_ {2}, with respect to this point C, due to the presence of wings 18. Therefore, if this receiving element 14 is pivoted around C, according to An angle of 180º, this receiving element is suitable for present two different configurations with respect to the element of immobilization 20.

In Figure 3, the support device 12 It is integrated in a 6_ {1} chest, which has dimensions minimum cross sections. In this configuration, soul 16 of the receiving element 14 is integral with the pin 10_ {1}, receiving at the same time the engine, which is not represented in this figure.

Wings 18 extend down, namely in opposition to the soul 22 of the immobilization element 20. On the other part, this soul 22 leans against the peripheral walls 8_ {1}, that belong to this chest 6_ {1}.

In figure 4, an average has been carried out return of the receiving element 14, around the center point C. Under these conditions, the wings 18 of this element 14 meet now directed towards the soul 22 of the immobilization element twenty.

In this figure, the support device 12 It is integrated in a 6_ {2} chest, which has dimensions maximum cross sections. It is noted that, in this arrangement, the wings 18 and 24 of the two elements 14 and 20, constituting the device 12, support each other.

This therefore ensures a blockage of the receiving element 14, by the immobilization element 20, what which prevents its rotation. It should be noted that, in one or another of the configurations of figures 3 and 4, screws 26 they are appropriate to cooperate with the hole walls oblong 24_ {2}, in order to ensure radial displacement between the receiving element 14 and the immobilization element twenty.

The asymmetric nature of the receiving element 14, due to the presence of the wings 18, is particularly advantageous with respect to the prior art illustrated in Figure 7. In this regard, this arrangement has been illustrated in Figure 8.
positive of the prior art 312 in a chest 306_ {1}, the dimensions of which are identical to those of the chest 6_ {1} of figure 3.

Moreover, in figure 9, this device of support 312 equips a chest 306_ {2}, which presents some maximum dimensions It is noted that this chest 306_2 is clearly smaller than the chest 6_2 of Figure 4 of such so that, if you want to integrate the technique device previous 312 in a larger chest, of type 6_ {2}, It is necessary to have a different model. In these conditions, the invention is particularly advantageous in economic terms, since the same support device allows adaptation to a larger number of chests than in the prior art.

In this regard, it should be noted that, in the support device 12 of the invention, the wings 18 do not hinder the arrangement of figure 3, since they do not form substantially no protrusion beyond the wings 24 of the element of immobilization 20. On the contrary, the presence of these wings 18 allows the adaptation of this device 12 in chests of large dimensions, as illustrated in figure 4. Indeed, thanks to these wings 18, which rest against wings 24 of the immobilization element 20, it is possible to move the two away from each other souls 16 and 22 of these elements 14 and 20, and therefore increase the vertical dimension of the chest set.

Figure 5 illustrates a first variant of embodiment of the invention. In this figure, to the elements mechanics analogous to those in figure 2 are assigned the same numerical references, increased by 100.

The support device 112 of this figure 5 differs from 12 in Figure 2, because the receiving element 114 It has a rectangular shape. More precisely, the part upper 116 of the receiving element 114 forms the area of reception, analogously to soul 16 in the device of the Figures 2 to 4. On the contrary, the blocking zone is not formed by wings, such as the 18 of figures 2 to 4, but by a extension 118, appropriate to rest against wings 124 of the immobilization element 120.

It is conceived that, as the extension 118 is located above or below the reception area 116, the support device 112 can be adapted to different sizes of chests. Thus, when the extension 118 is placed below of zone 116, the device 112 may be integrated in a small chest, such as the one in figure 3. On the contrary, when this extension 118 is located above zone 116, by a half turn of the receiving element 114 around from point C, the support device 112 may be integrated in a large chest such as the one in figure 4.

It should be noted that extension 118 is perforated by a supplementary hole 119, of center C ', also liable to receive the pin 10_ {1}. Under these conditions, this extension 118 may also constitute a reception area of the motor, when the aforementioned bumper penetrates into this hole 119. Thus, when this part 118 forms an area of reception, part 116 of receiving element 114 then forms a blocking zone

It will be highlighted finally that, to pass from one position of support device 112 to another, just do pass the pin 10_ {1} of a first hole 116_ {2} or 119 towards the other hole 119 or 116_ {2}. This operation is equivalent to which consists in swinging the receiving element 114 180º, respectively around point C or C '.

Figure 6 illustrates a third mode of embodiment of the invention. In this figure, the mechanical elements  analogous to those in figure 5 are designated with the same reference numbers, increased by 100.

The support device 212, which is illustrated in this figure 6 differs from 112 in figure 5, in that the walls sides 216_ {3} of the receiving element 214, which form stand out in opposition to the facing face, they form sliding. Thus, the free end 224_ {1} of each wing 224 of the element of immobilization 220 can be slidably received in these slides 216_ {3}.

In addition, the relative position of these wings and of These slides can be regulated, through the cooperation of a screw 226, integral with a corresponding slide, which is liable to assign different positions along a corresponding port 224_ {2}, practiced at each free end 224_ {1}.

Finally, the wings 224 of the element of immobilization 220 are each provided with a stepped 224_ {3}, so that the proximal portion of these wings, in the proximity of the soul 222, leans against the face of the chest, in service. In addition, a return 223 form stands out from this soul 222, as opposed to this face, to ensure a better distribution of the efforts. It should be noted that, in service, this return is also applied against a facing peripheral wall, which It belongs to the drawer.

It will be noted that the embodiment of the Figures 5 and 6 have specific advantages. Indeed for move from one configuration to another, it is possible first of all to do pivot the receiving element around the center of a corresponding hole C or C '. This operation can be performed. also by a translation of the receiving element, corresponding to the passage of the pin 10_ {1}, of a hole towards the other. It is conceived that this last possibility confers, for a Operator, great convenience of use.
