Description

The present invention relates to a device for supporting a tree

  winding of a closing or sun protection system, as well as a closure or sun protection system provided with

  at least one such support device.

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

  The invention is more particularly a closure or sun protection system, of the aforementioned type, which is provided with a screen whose winding shaft is received in a trunk. In this regard, it should be noted that the invention finds application to any type of winding shaft, regardless of the mode of maneuver of the latter, namely including motor, winch and crank, or by strap.

  It is known to place, in the vicinity of the side cheeks of the trunk, a support device for receiving a corresponding end of the winding shaft. For this purpose, US-A-4,234,032 teaches to provide each cheek by means of a pin, adapted to receive this support device.

  Also known is a support device, marketed by the ASA company under the reference 2203045, which is shown in Figure 7 attached. This device 312 firstly comprises a receiving element 314 of the aforementioned end of the winding shaft, which is hollowed out of a central orifice 3162 for the 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 comprises an immobilizing element 320, substantially U-shaped. In use, the core 322 of this element 320 rests against the peripheral walls of the trunk, while its wings 324 abut against the side walls. facing the receiving element 314, so as to prevent rotation of the latter.

  This support device of the ASA company is of significant interest, especially in that it prevents any drilling and screwing on the cheek of the trunk. This therefore gives an advantageous aesthetic to the installation of closure or sun protection that is equipped.

  The disadvantage associated with this support device lies in its lack of versatility.

  Indeed, the length of a closing screen or sun protection is variable, depending on the size of the area it must cover. In particular, if it is a closure screen, the thickness and the pitch of the constituent blade thereof can vary significantly.

  As a result, the diameter of this screen, once wound, is likely to have very different dimensions from one installation to another. For this purpose, it is customary for manufacturers to generally provide at least two boxes of appropriate sections to meet these requirements. Moreover, since the dimensions specific to each chest vary from one manufacturer to another, there is on the market a wide range of sections of boxes.

  However, the equipment proposed by the company ASA does not cover, satisfactorily, all of these sections. It is therefore necessary to have several different supports, each of which is adapted to a corresponding size of chest. It is therefore conceivable that this situation involves significant costs, especially in terms of stocks and number of commercial references.

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

  For this purpose, it relates to a device for supporting a winding shaft of a closure or sun protection screen, this shaft being received at least partly in a trunk, this device comprising a receiving element for an end of said shaft, comprising radial immobilization means relative to a side wall of said trunk, in particular at least one orifice intended for the passage of a stud belonging to said side wall of said trunk, this device further comprising an element of immobilization of the receiving element, adapted to bear against a peripheral wall of said chest, characterized in that, in the plane of the or each orifice, the receiving element is asymmetrical with respect to the center of the or each orifice, this receiving element being adapted to have at least two different configurations with respect to the immobilizing element.

  According to other features of the invention; the receiving element is hollowed out with a single orifice for passing the stud, this receiving element being able to have two different configurations with respect to the immobilizing element, by rotating 180 about the center of said orifice; the receiving element is hollowed out with at least two selectively passing orifices of said stud, this receiving element being capable of presenting at least two different configurations with respect to the immobilizing element by means of a rotation of 180 around from the center of each orifice, a translation corresponding to the passage of the nipple from one orifice to another orifice; the receiving member has a receiving zone of the end of said shaft, and a clean blocking zone at least partially supported in at least one of said positions against the immobilizing element; - The receiving element has a generally U-shaped, whose core is hollowed out of said single orifice and forms said receiving zone and whose two wings form said locking zone; the receiving member generally has a rectangular shape, the locking zone being formed by a massive extension of the receiving zone, the receiving zone and the extension being each hollowed out with a corresponding orifice, adapted to selectively receive said nipple; - Means are provided for mutual attachment of the receiving element with respect to the immobilizing element, according to different positions; - The securing means comprise at least one screw, integral with the receiving member, which is adapted to be secured, adjustably, along the walls of at least one slot in the immobilizing element; - The receiving element is provided with at least one slide, adapted to slidably receive said immobilizing element, the or each screw being integral with the or each slide; - There are two slides, adapted to receive the free ends of two wings of the immobilizing element 30, each wing being provided with a corresponding shoulder.

  The invention also relates to a closure or sun protection system comprising a winding shaft, a receiving box of this shaft, at least one device for supporting at least one end of this winding shaft, the or each support device being provided in the vicinity of a corresponding side wall of the box, characterized in that the or each support device is as defined above.

  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. non-limiting 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; FIG. 2 is a front view illustrating the two constituent elements of a support device belonging to the installation of FIG. 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 closure or sun protection system, partially shown in FIG. 1, comprises a shaft 2 controlled by an electric motor 4. A closing apron, not shown, is suitable for being wound around the aforementioned shaft. .

  This tree is received in a box, or box 6, which has peripheral walls 8, as well as two side walls, which are formed by cheeks, only one of which is shown in FIG. 1. The various mechanical members mentioned above above are of conventional type, so that they are described succinctly.

  The installation further comprises a device for supporting the winding shaft 2, which is generally designated by the reference numeral 12.

  As shown in particular in Figure 2, this device comprises a first element 14, also called receiving element, which has a generally U-shaped. It thus has a core 16, which comprises a central portion 161, in which is formed a hole 162 receiving a pin 101r extending from the cheek 10 facing. This orifice 162 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 163 projecting from the central portion 161 in the direction of the motor, namely opposite the cheek 10. This core 16 thus forms, in known manner, a receiving zone the corresponding end of the motor 4. Such a reception can be ensured, for example, by screwing the motor in the central portion 161 and / or latching thereof at the side walls 163.

  The receiving element 14 is also provided with two wings 18, which extend from the side walls 163 of the core 16.

  The support device 12 comprises, in addition to the receiving member 14, an immobilizing element 20, also in the form of a U. The core 22 of the latter is able to bear against one of the peripheral walls 8 of the box 6, while its wings 24 are adapted to prevent the pivoting of the receiving element 14, as will be seen in what follows.

  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 242, while a screw 26 is integral with the two wings 18 of the receiving element 14. The two elements 14 and 20, in this case in a vertical direction in FIGS. 3 and 4, can be slid relative to one another and then held in position by screwing the screws 26 against the walls. oblong holes 242.

  C is the center of the orifice 162, 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 162 , relative to this point C, because of the presence of the wings 18. Therefore, if this receiving element 14 is rotated around C at an angle of 180, this receiving element is able to present two different configurations with respect to the immobilizing element 20.

  In Figure 3, the support device 12 is integrated in a trunk 61, which has minimum transverse dimensions. In this configuration, the core 16 of the receiving member 14 is integral with the pin 101, while receiving the motor, which is not shown in this figure.

  The wings 18 extend downwards, namely opposite the web 22 of the immobilizing element 20. Furthermore, this web 22 bears against the peripheral walls 81r belonging to this trunk 61.

  In FIG. 4, a half-turn of the receiving element 14 is made around the central point C. Under these conditions, the wings 18 of this element 14 are now directed towards the core 22 of the immobilizing element 20.

  In this figure, the support device 12 is integrated in a box 62 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 242, in order to ensure a radial clearance between the receiving element 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 trunk 3061r whose dimensions are identical to those of the trunk 61 of FIG.

  Moreover, in FIG. 9, this support device 312 equips a box 3062, having maximum dimensions. Note that this chest 3062 is significantly smaller than that 62 of Figure 4 so that, if it is desired to integrate the device of the prior art 312 into a larger box, such as the one 62, 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 regard, 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, since they do not substantially project beyond wings 24 of the immobilizing element 20. In contrast, the presence of these wings 18 allows the adaptation of this device 12 in large boxes, as shown in Figure 4. Indeed, with these wings 18, which abut against the wings 24 of the immobilizing element 20, it is possible to mutually separate the two webs 16 and 22 of these elements 14 and 20, and thus to increase the vertical dimension of the set of the chest.

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

  The support device 112 of this FIG. 5 differs from that of FIG. 2 in that the receiving element 114 has a rectangular shape. More specifically, the upper portion 116 of the receiving member 114 forms the receiving zone, similarly to the core 16 in the device of FIGS. 2 to 4. On the other hand, the locking zone is not formed by wings, such as those 18 of Figures 2 to 4, but by an extension 118, adapted to bear against the wings 124 of the immobilizing element 120.

  It will be appreciated that depending on whether the extension 118 is above or below the receiving area 116, the support device 112 can accommodate different sizes of cases. Thus, when the extension 118 is placed below the zone 116, the device 112 can be integrated in a small box, such as that of FIG. 3. On the other hand, when this extension 118 is situated above the zone 116 by half a turn of the receiving element 114 around the point C, the support device 112 can be integrated into a large box, such as that of FIG. 4.

  It should be noted that the extension 118 is hollowed out with an additional orifice 119, of center C ', also capable of receiving the stud 101. Under these conditions, this extension 118 may also constitute an engine receiving zone, when the The aforementioned nipple penetrates into this orifice 119. Thus, when this portion 118 forms a receiving zone, the portion 116 of the receiving element 114 then forms a blocking zone.

  Finally, it will be noted that, to pass from one position of the support device 112 to another, it is sufficient to pass the pin 101 of a first port 1162 or 119 to the other orifice 119 or 1162. This operation is equivalent to that of rotating the receiving element 114 of 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 of FIG. 5 are assigned the same reference numbers, increased by 100. The support device 212, illustrated in this FIG. 6, differs from that 112 of FIG. the side walls 2163 of the receiving element 214, which protrude away from the facing cheek, form slideways. Thus, the free end 2241 of each wing 224 of the immobilizing element 220 can be slidably received in these slides 2163.

  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 2242, arranged in each free end 2241.

  Finally, the wings 224 of the immobilizing element 220 are each provided with a shoulder 2243, so that the proximal portion of these wings, adjacent to the core 222, bears against the cheek of the chest, 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 pin 101 from one orifice to the other. It is conceivable that this latter possibility confers a great convenience of use, for an operator.
