Description

The present invention relates to a device for support of a winding shaft of an installation of closure or sunscreen, as well as a closure or sun protection system provided at least one such support device.

Closure means doors, gates, shutters and other equivalent equipment.

The invention aims more particularly at a closure or sun protection system of the type aforementioned, which is equipped with a screen whose shaft winding is received in a chest. In this respect, it is note that the invention finds application to any type winding shaft, irrespective of the maneuvering mode of the latter, namely in particular by motor, winch and crank, or by strap.

It is known to place, in the vicinity of the cheeks side of the boot, a support device, intended for receive a corresponding end of the tree winding. For this purpose, US-A-4,234,032 teaches provide each cheek with a nipple, suitable for receiving this support device.

There is also known a support device, marketed by ASA under the reference 2203045, which is shown in Figure 7 attached. This device 312, which includes all the features of the preamble of appended claim 1, firstly comprises a receiving element 314 of the aforementioned end of the winding shaft, which is hollowed out with a central orifice. 316 ₂ passage of the nipple of the cheek. This receiving element 314 has a rectangular shape generally symmetrical with respect to the center of this orifice.

The support device also includes an element 320, substantially U-shaped. service, the soul 322 of this element 320 rests against the peripheral walls of the trunk, while its wings 324 come to bear against the side walls next to the receiving element 314, so as to prevent the rotation of the latter.

This support device from the ASA company presents a noticeable interest, especially in that it avoids any drilling and screwing on the cheek of the chest. This confers therefore an advantageous aesthetic to the installation of closure or solar protection that is equipped.

The disadvantage related to this support device resides however in its lack of versatility.

Indeed, the length of a closing screen or sun protection is variable, depending on the dimensions of the area to be covered. In particular, if this is a closing screen, the thickness and the pitch of the constituent blade of it can vary so sensitive.

As a result, the diameter of this screen, once coiled, is likely to have very large dimensions different from one installation to another. For this purpose, he It is customary for manufacturers in general to minus two boxes of appropriate sections, in order to meet these requirements. Moreover, since the dimensions of each chest vary from one manufacturer to the other, there exists on the market a vast declination of sections of chests.

However, the equipment proposed by ASA does not allow not cover, satisfactorily, all of these sections. It is therefore necessary to have several different supports, each of which is suitable for one dimension matching chest. It is therefore conceivable that this situation involves significant costs, particularly in terms of stocks and number of commercial references.

Also known from EP-A-0 784 145, a component with a curtain, a tree, as well as means of support for this tree, which include a console, which is screwed on the cheek of the chest. This known solution, however, is less convenient than the support device of ASA, described above, especially as it involves a screwing.

That being said, the invention proposes to remedy to all the disadvantages of the prior art mentioned above.

For this purpose, it relates to a device for support according to claim 1 attached.

Advantageous features of the invention make the subject of dependent claims 2 to 10.

The subject of the invention is also a plant of closure or sun protection according to claim 11 annexed.

The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of three embodiments of a support device according to its principle, given solely as examples. nonlimiting and with reference to the accompanying drawings, in which:

• Figure 1 is an exploded perspective view, partially illustrating a closure system or solar protection according to the invention;
• Figure 2 is a front view, illustrating the two components of a support device belonging to the installation of Figure 1;
• Figures 3 and 4 are front views, illustrating two chests, respectively minimum and maximum dimensions, in which can be integrated the support device of Figure 2;
• Figures 5 and 6 are front views, similar to Figure 2, illustrating two alternative embodiments of a support device according to the invention;
• Figure 7, previously mentioned, is a front view illustrating a support device of the prior art; and
• FIGS. 8 and 9 are front views, similar to FIGS. 3 and 4, illustrating two chests, the dimensions of which are respectively minimum and maximum, integrating the device of FIG.

The installation of closing or sunscreen, partially shown in FIG. a shaft 2, controlled by an electric motor 4. An apron closure, not shown, is suitable for being wound around the aforementioned tree.

This tree is received in a chest, or box 6, which has peripheral walls 8, as well as two walls side, which are formed by cheeks, of which only one 10 is shown in Figure 1. The various organs mentioned above are of the classic type, of so that they are described succinctly.

The installation also comprises a device for support of the winding shaft 2, which is designated in together by reference 12.

As shown in particular in Figure 2, this device comprises a first element 14, also called receiving element, which generally has a U-shape. It thus has a core 16, which comprises a central portion 16 ₁ , in which is formed a port 16 ₂ receiving a stud 10 ₁ , extending from the cheek 10 opposite. This orifice 16 ₂ thus makes it possible to radially immobilize the receiving element 14 with respect to this cheek 10.

The core 16 also has two side walls 16 ₃ protruding from the central part 16 ₁ in the direction of the motor, namely opposite the cheek 10. This core 16 thus forms, in a known manner, a zone for receiving the corresponding end of the motor 4. Such a reception can be ensured, for example, by screwing the motor in the central portion 16 ₁ and / or latching thereof at the side walls 16 ₃ .

The receiving element 14 is also provided with two wings 18, which extend from the side walls 16 ₃ of the core 16.

The support device 12 comprises, in addition to the element receiving element 14, an immobilizing element 20, also in the shape of a U. The soul 22 of it is fit to come into bearing against one of the peripheral walls 8 of the box 6, while its wings 24 are able to prevent the pivoting of the receiving element 14, as will be seen in the following.

Finally, there is provided means for mutually securing the receiving element 14 and the immobilizing element 20, while ensuring a radial movement between these two elements. For this purpose, the two wings 24 of the immobilizing element 20 are hollowed out with respective oblong holes 24 ₂ , whereas a screw 26 is integral with the two wings 18 of the receiving element 14. It is therefore conceivable that it is possible to slide with respect to one another these two elements 14 and 20, in this case in a vertical direction in FIGS. 3 and 4, and then to hold them in position by screwing the screws 26 against the walls of the oblong holes 24 ₂ .

C is the center of the orifice 16 ₂ , formed in the core 16. It is therefore conceivable that, contrary to the prior art, the receiving element 14 is not symmetrical, in the plane of the orifice 16 ₂ , with respect to this point C, because of the presence of the wings 18. Therefore, if this reception element 14 is rotated around C at an angle of 180 °, this receiving element is clean. to present two different configurations with respect to the immobilizing element 20.

In Figure 3, the support device 12 is integrated in a trunk 6 ₁ , which has minimum transverse dimensions. In this configuration, the core 16 of the receiving element 14 is integral with the stud 10 ₁ , while receiving the motor, which is not shown in this figure.

The flanges 18 extend downwards, namely opposite the web 22 of the immobilizing element 20. Furthermore, this web 22 bears against the peripheral walls 8 ₁ belonging to this trunk 6 ₁ .

In Figure 4, we made a half-turn of the receiving element 14 around the central point C. In these conditions, the wings 18 of this element 14 are now directed to the soul 22 of the element immobilization 20.

In this figure, the support device 12 is integrated in a box 6 ₂ having maximum transverse dimensions. Note that in this arrangement, the wings 18 and 24 of the two elements 14 and 20, constituting the device 12, bear against each other.

This thus ensures a blocking of the receiving element 14, by the immobilizing element 20, which prevents rotation. It should be emphasized that, in one or other of the configurations of FIGS. 3 and 4, the screws 26 are adapted to cooperate with the walls of the oblong holes 24 ₂ , in order to ensure a radial clearance between the element of FIG. receiving 14 and the immobilizing element 20.

The asymmetrical nature of the receiving element 14, due to the presence of the wings 18, is very advantageous compared with the prior art illustrated in FIG. 7. For this purpose, FIG. of the prior art 312 in a chest 306 ₁ , whose dimensions are identical to those of the chest 6 ₁ of Figure 3.

Moreover, in FIG. 9, this support device 312 equips a box 306 ₂ , having maximum dimensions. It should be noted that this box 306 ₂ is considerably smaller than that 6 ₂ in FIG. 4 so that, if it is desired to integrate the device of the prior art 312 into a larger box, such as that 6 ₂ , it is necessary to have a different model. Under 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 state of the art.

In this respect, it should be noted that in the support device 12 of the invention, the wings 18 are not troublesome in the arrangement of Figure 3, being given that they do not substantially project beyond the wings 24 of the immobilizer 20. On the other hand, presence of these wings 18 allows the adaptation of this device 12 in large chests like illustrated in Figure 4. Indeed, thanks to these wings 18, which come to bear against the wings 24 of the element immobilizer 20, it is possible to move mutually the two souls 16 and 22 of these elements 14 and 20, and therefore to increase the vertical dimension of the whole chest.

Figure 5 illustrates a first variant of embodiment of the invention. In this figure, the elements similar to those in Figure 2 are affected the same reference numbers, increased by 100.

The support device 112 of this FIG. 5 differs from that 12 of Figure 2, in that the element of receiving 114 has a rectangular shape. In a way more precise, the upper part 116 of the element of reception 114 forms the reception zone, in a similar way to the core 16 in the device of FIGS. 2 to 4. However, the blocking zone is not formed by wings, such as those 18 in FIGS. 2 to 4, but by a extension 118, fit to bear against the wings 124 of the immobilizing element 120.

It is conceivable that, depending on whether the extension 118 is located above or below reception area 116, the support device 112 can adapt to different Chest sizes. So, when the extension 118 is placed below the zone 116, the device 112 can be integrated in a small chest, like the one in the figure 3. On the other hand, when this extension 118 is located above of zone 116, by half a turn of the element reception point 114 around the point C, the support 112 can be integrated in a large box, such that of Figure 4.

It should be noted that the extension 118 is hollowed out with an additional orifice 119, with a center C 'capable of also receiving the stud 10 ₁ . Under these conditions, this extension 118 may also constitute a motor receiving zone, when the aforementioned pin enters this orifice 119. Thus, when this portion 118 forms receiving zone, the portion 116 of the receiving element 114 then forms blocking area.

Finally, it will be noted that, to pass from one position of the support device 112 to another, it suffices to pass the pin 10 ₁ of a first orifice 116 ₂ or 119 to the other orifice 119 or 116 ₂ . This operation is equivalent to that of rotating the receiving element 114 by 180 °, respectively around the point C or C '.

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

The support device 212, illustrated in this FIG. 6, differs from that 112 of FIG. 5, in that the side walls 216 ₃ of the receiving element 214, which protrude away from the opposite cheek, form slides. Thus, the free end 224 ₁ of each wing 224 of the immobilizing element 220 can be slidably received in these slides 216 ₃ .

In addition, the relative position of these wings and of these slides can be adjusted, by cooperation of a screw 226, integral with a corresponding slide, which is capable of affecting different positions along a corresponding light 224 ₂ , arranged in each free end 224 ₁ .

Finally, the wings 224 of the immobilizing element 220 are each provided with a shoulder 224 ₃ , so that the proximal portion of these wings, adjacent to the core 222, bears against the cheek of the trunk, in use . In addition, a return 223 protrudes from this core 222, opposite this cheek, so as to ensure a better distribution of efforts. It should be noted that, in use, this return is also pressed against a peripheral wall opposite, belonging to the box.

It should be noted that the embodiment of FIGS. 5 and 6 has specific advantages. Indeed, to move from one configuration to another, it is first possible to rotate the receiving element around the center of a corresponding hole C or C '. This operation can also be performed by means of a translation of the receiving element, corresponding to the passage of the stud 10 ₁ from one orifice to the other. It is conceivable that this latter possibility confers a great convenience of use, for an operator.
