Description

TECHNICAL FIELD The present invention relates to a method for assembling a closure or sun protection system, in particular an indoor blind type. The invention also relates to a support system, designed to implement such a method of assembly. The invention also relates to an installation comprising such a support system. The field of the invention is that of blinds or roller shutters, intended to equip a building opening such as a door or a window arranged in a wall or a roof. In particular, the field of the invention is that of indoor blinds with a single control. In known manner, an inner blind comprises a box, a blade apron and guidewires, a cable winding shaft, and a drive motor of the shaft. The deck goes up or down to clear or hide the opening, depending on the rotational movement of the shaft driven by the engine. When assembling an interior blind with a single control, placing the motor in the housing is a delicate operation. Under these conditions, the engine is equipped with a support system facilitating its positioning in the box. The support system typically comprises two support members attached to the longitudinal ends of the engine. This attachment is usually made by clipping, when the support elements and the motor are located outside the box. Fixing the support elements on the engine inside the box would be difficult because of the necessary clipping efforts.

Conventionally, once the support elements attached to the motor, the assembly is slidably inserted through an open end of the housing, and then moved in translation to its final position. This insertion step is relatively difficult to accomplish, especially because of the adjustments between the support elements and the box, and can be very long for awnings having a large width.

The object of the present invention is to provide an improved assembly method, overcoming the above disadvantages. For this purpose, the subject of the invention is a method of assembling a closure or sun protection system, in particular of the indoor blind type, comprising: a box, a motor housed in the box, a support system designed for position the engine in the box, and an apron designed to be lowered or raised according to the commands received by the engine. The assembly method comprises: a manufacturing step a) of manufacturing the box, the motor, the support system and the apron; and then a preparatory step b) of fixing the motor to the support system out of the box, to form a motor assembly. The assembly method is characterized in that it also comprises a mounting step c) of mounting the motor assembly in the box by pivoting and clipping. Thus, the invention makes it easier and therefore accelerates the assembly step of the motor assembly in the box. As a result, the assembly process is facilitated and accelerated, which reduces the time and cost of manufacturing the installation. Instead of sliding slowly from one end of the box to its final position, according to a longitudinal translational movement, the motor unit can be directly and quickly mounted by the upper opening of the box, following a rotational movement. According to other advantageous features of the assembly step c) of the assembly method according to the invention, taken separately or in combination: the motor assembly during pivoting temporarily deforms a wall of the box. - Parts of the support system are deformed successively and temporarily in contact with a wall of the box while the motor assembly is being pivoted. - The motor assembly is introduced into the housing in an insertion direction and at the end of the mounting step c), at least a portion of the support system is retained in the housing in a direction opposite to the direction of 'insertion. - A stud belonging to the support system engages with a lip 25 formed on a wall of the box. - The pivoting of the motor assembly is formed around a pivot axis located at the lip and the pin. Advantageously, when the installation is in use, the pin provides an additional function of absorption of torque peaks of the motor.

According to a preferred embodiment, the support system comprises two support elements arranged at the longitudinal ends of the motor. The invention also relates to a support system, designed to implement the assembly method as mentioned above. The support system includes at least one support member which includes: a motor attachment port, engagement means with the housing upon pivoting, and blocking means in position in the housing after clipping.

The invention also relates to a closure system or sun protection, including indoor store type, comprising: a box, a motor housed in the box, a support system as mentioned above, and an apron intended to be lowered or raised according to the commands received by the engine.

The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example and with reference to the appended drawings in which: FIG. 1 is a perspective view of an installation of the type internal blind according to the invention; Figure 2 is a view along the arrow II in Figure 1, on a larger scale, showing only a support member equipping the inner blind; Figure 3 is a perspective view similar to Figure 1, on a larger scale, showing two support elements and the motor equipping the inner blind, in disassembled configuration; Figure 4 is a perspective view similar to Figure 3 showing the two support members and the engine in assembled configuration; Figure 5 is a perspective view similar to Figure 1, showing only the box and the engine equipped with support elements before mounting in the box; and Figures 6 to 10 are views similar to Figure 2, on a smaller scale, showing the mounting of the motor and support members in the box. In Figure 1 is shown an installation 1, according to the invention, closing or sun protection, in this case the type of inner blind. The blind 1 comprises a box 10, a motor 20, a support system 30, an apron 50, a shaft 60 and reels 70. The support system 30 comprises two support elements 40 designed to be assembled with the motor 20, thus forming a one-piece motor assembly, intended to be mounted in the box 10. In practice, the support system 30 is designed to position the motor 20 in the box 10. When the blind 1 is assembled, then the box 10, the motor 20, the support system 30, the shaft 60 and the reels 70 are generally centered on a longitudinal axis X10 of the box 10. The box 10 is elongate between two ends 10A and 10B, in a longitudinal direction defined parallel to the X10 axis. The casing 10 is preferably made of aluminum or PVC. The box 10 has a bottom wall 11, a front wall 12 and a rear wall 13. The upper side opposite the bottom wall 11, the box 10 has an upper opening 14. The walls 11, 12 and 13 define a space 3032998 The interior space 15 is closed by the walls 11, 12 and 13, and open at the upper opening 14 and the longitudinal ends 10A and 10B. The walls 12 and 13 comprise two upper borders, 16 and 17 respectively, delimiting the upper opening 14. The walls 11, 12 and 13, the opening 14 and the borders 16 and 17 each extend in a direction parallel to the X10 axis. The border 16 comprises a lip 162 curved towards the interior space 15. The border 16 delimits a groove 164. Likewise, the edge 17 comprises a lip 172 curved towards the interior space 15. The border 17 delimits a groove 174. In a plane perpendicular to the axis X10, each of the lips 162 and 164 has a crooked hook shape in the interior space 15. The motor 20 comprises a body 22 elongated between two longitudinal ends 24. Once disposed in the space inside 15 of the box 10, the motor 20 extends in a direction parallel to the axis X10. In the body 22 are housed the constituent actuator devices of the motor 20.

In the example of FIGS. 1 to 10, each end 24 of the motor 20 comprises two parts 26 and 28 arranged projecting from the body 22. More precisely, the portion 26 is disposed projecting out of the portion 28 to the Opposite the body 22, while the portion 28 is protruded from the body 22. When the motor 20 is in use, the body 22 and the parts 28 are held in position in the box 10 thanks to the support system 30 while the parts 26 are rotatable about the axis X10. Part 26 has hexagonal external and internal forms. The portion 26 defines an internal cavity 260 provided to receive the shaft 60. The cavity 260 and the shaft 60 have complementary hexagonal sections, so that the shaft 60 is secured to the portion 26 rotating around the X10 axis. The portion 28 is secured to the body 22. For example, the body 22 and the portion 28 may be integrally molded. Part 28 has a complex external shape, designed to cooperate mechanically with the corresponding support member 40. The portion 28 comprises four protuberances 282 formed radially at the axis X10 and separated by four recesses 284. The protuberances 282 and the recesses 284 are regularly distributed about the axis X10. The apron 50 is designed to be lowered or raised according to the commands received by the motor 20. The apron 50 comprises a series of blades 52 parallel to each other, including a final blade 54 which is farthest from the box 10. The blades 52 35 extend between the ends 10A and 10B of the box 10, each in a direction parallel to the axis X10.

The apron 50 also comprises cables 56 for guiding the blades 52. The cables 56 pass through the blades 52, preferably being regularly distributed along the axis X10. In the example of Figure 1, the apron 50 comprises three cables 56, equidistant in pairs in a direction parallel to the axis X10. The cables 56 have upper ends 57 fixed to the winders 70 integral with the shaft 60, as well as the lower ends 58 fixed under the final blade 54. When the deck 50 is raised, the blades 52 are tightened against one another against the wall lower 11 of the box 10, while the cables 56 are wound around the reels 70 and the shaft 60. When the apron 50 is lowered, as in the example of 1, the blades 52 and cables 56 s extend generally in the same vertical plane, with the blades 52 which are parallel to each other and to the axis X10, while the cables 56 are parallel to each other and orthogonal to the axis X10. The apron 50 may include a device for inclining the blades 52, for tilting these blades 52 when the apron 50 is partially or completely lowered.

This inclination device is not shown for purposes of simplification. The shaft 60 is designed to cooperate with the motor 20 and the reels 70. The shaft 60 consists of two distinct parts received at the ends 24 of the motor 20. These parts are prevented from being separated from the motor 20 by bushings. stop not shown. The shaft 60 has a hexagonal outer section. Thus, when the shaft 60 is housed in the motor 20 and the reels 70, then the parts 26 of the motor 20, the shaft 60 and the reels 70 are integral in rotation about the axis X10. The support members 40 are provided to be fixed to the longitudinal ends 24 of the motor 20, by clipping on the parts 28. The elements 40 are preferably made of plastic, for example polyamide.

Each element 40 comprises a central body 41 provided with an orifice 42 for receiving the portion 28 of one end 24 of the motor 20. Each element 40 comprises a lower side 401, a front side 402, a rear side 403 and an upper side 402. Each element 40 comprises a front upper corner 46, a rear upper corner 47, a lower front corner 48 and a rear lower corner 49. The lower side 401 comprises a reinforcing bar 410 which extends between the the rear side 403 has an outer surface 430 which extends between the corners 47 and 49 and has a rounded convex shape. The wedge 46 has an orifice 460, a front leg 462 and an upper leg 464. The orifice 460 is delimited by the arms 462 and 464, as well as by the body 41. The arm 464 comprises a hollow 466 open on the upper side 404, and a pin 468 which extends from the upper side 404 in the extension of the branch 3032998 6 462. The stud 468 borders the hollow 466 of the front side 402. When the element 40 is positioned in the box 10, the hollow 466 receives the lip 162, while the stud 468 is housed in the groove 184, as detailed below. The wedge 47 comprises an orifice 470, a rear branch 472 and an upper branch 474. The orifice 470 is delimited by the branches 472 and 474, as well as by the body 41. The wedge 47 has a hollow 476 formed at the junction between the branches 472 and 474, the outer side opposite the orifice 470. When the element 40 is positioned in the box 10, the hollow 476 receives the lip 172, as detailed below. The wedge 48 has an orifice 480 and a front branch 482. The orifice 480 is delimited by the branch 482, the body 41, as well as the sides 401 and 402. The wedge 49 has an orifice 490 and a rear branch 492. The orifice 490 is delimited by the branch 492, the body 41, as well as the sides 401 and 403. The orifices 42, 460, 470, 480 and 490 pass through the element 40 in a direction parallel to the axis X10. Ports 460, 470, 480, and 490 provide some flexibility to member 40 around port 42, which is adapted to receive one of the portions 28 of motor 20. Port 42 includes a complex internal shape The orifice 42 comprises four recesses 422 formed radially on the axis X10 and separated by four U-shaped protuberances 424. The recesses 422 and the protuberances 424 are regularly distributed around it. of the X10 axis. The recesses 422 are provided to receive the protuberances 282, while the protuberances 424 are provided to be accommodated in the recesses 284, when the element 40 is mounted on the motor 20. Thus, when the support system 30 is positioned in the box 10, the motor 20 secured to the elements 40 can not pivot about the axis X10, because the parts 28 are blocked by clipping in the orifices 42. The method of assembly of the blind 1 is detailed below. The method comprises a manufacturing step a) of manufacturing the elements 10, 20, 30, 50, 60 and 70 constituting the blind 1. The method then comprises a preparatory step b), illustrated in Figures 3 and 4, consisting of attaching the motor 20 to the support system 30 out of the well 10 to form the motor assembly 20 + 30. Specifically, the support members 40 are attached to the ends 24 of the motor 20. The method then comprises a mounting step c), illustrated in Figures 5 to 10, of mounting the motor assembly 20 + 30 in the box 10 by pivoting R1 35 and clipping. Only one element 40 is visible in FIGS. 6 to 10, it being understood that the other element 40 is situated behind.

Figure 5 shows the motor assembly 20 + 30 positioned above the housing 10. The motor assembly 20 + 30 is ready for insertion into the interior space 15, in an insertion direction D1 which is orthogonal to the X10 axis, and not parallel to the X10 axis. Figure 6 shows the wedge 47 positioned in the rim 16. Specifically, the stud 468 is inserted into the groove 164, while the recess 466 receives the lip 162. Engaging the wedge 46 with the rim 16 facilitates pivoting R1 of the element 40. At the same time, the wedge 49 and the surface 430 bear against the edge 17, which deforms the wall 13. FIGS. 6 to 9 show the pivoting R1 of the motor assembly 20+ 30, including the element 40. The pivot R1 is a rotational movement centered on an axis X30, which is parallel to the axis X10 and is located generally at the lip 162 and the pin 468. During the pivoting R1, the wedge 49, then the surface 430, then the wedge 47 slide against the edge 17, deforming the wall 13. Figure 10 shows the motor assembly 20 + 30 in the final position in the caisson 15 10. The pin 468 is positioned in the groove 164, while the lip 162 is received in the hollow 466. In addition, the The lip 172 is received in the recess 476, which prevents pivoting of the element 40 in a direction of rotation R2 opposite to the direction of rotation R1. In addition, the branches 462 and 472 bear against the walls 12 and 13, while the side 401 bears against the wall 11. The element 40 is thus held firmly in position in the interior space 15 of the box 10, with its corners 46 and 47 blocked by the borders 16 and 17 on either side of the opening 14, while its sides 401, 402 and 403 are locked against the walls 11, 12 and 13. Thus, 20 + 30 motor assembly is inserted into the box 10 generally in the direction D1 and clipped by pivoting R1. At the end of the mounting step c), the wedges 46 and 47 are retained in the casing 10 by the borders 16 and 17 in a direction D2 opposite to the direction D1, preventing the motor assembly 20 + 30 from emerging. by the opening 14. The mounting of the element 40 by pivoting R1 keeps the stud 468 engages under the lip 162 of the box 10, which could not be retained in case of mounting by translation in the direction D1 by the top of the box 10. In practice, in addition to the pivot function, this pin 468 provides an additional function of absorbing torque peaks of the motor 20 when the blind 1 is in use. These peaks can occur in particular when the blind 1 is brought into abutment. This pivoting mounting R1 and clipping requires little effort and, thanks to the rounded shape of the external surface 430 of the element 4, does not deform only slightly the box 10 during the pivoting R1. Indeed, this surface 430 is designed to follow the pivot trajectory R1. The shape of the surface 430 depends on the geometry of the box 10 and can be adapted to the shapes and dimensions of the box 10. For the sake of simplification, only the wall 13 of the box 10 is shown temporarily deformed in FIGS. 6 to 9 illustrating the mounting step c).

Nevertheless, in practice, the wall 12 of the box 10 is also likely to be temporarily deformed during the pivoting R1. Preferably, the element 40 is of rigid material and sized to not deform during the pivoting R1. In optional variant, when the dimensions and the material of the element 40 allow it, its parts 49, 403 and 47 are also capable of being deformed, successively and temporarily, against the wall 13 during the pivoting R1. The method also comprises complementary mounting steps, consisting in mounting the shaft 60 in the motor 20 and the reels 70, and then mounting the cables 56 of the deck 50 on the reels 70. Furthermore, the installation 1 can be shaped differently. Figures 1 to 10 without departing from the scope of the invention. In particular, the support system 30 may have any other configuration adapted to the intended application. In a variant that is not shown, the support system 30 may comprise a single support element 40. For example, this support element 40 may be positioned in the middle of the motor 20 in the longitudinal direction. In this case, the width of the support member 40 in a direction parallel to the axis X10 can be adapted accordingly. According to another variant not shown, the ends 24 of the motor 20 and the orifices 42 of the elements 40 may have different configurations, allowing their coupling. Similarly, the ends 24 of the motor 20 and the shaft 60 may have different configurations, allowing their coupling.

According to another variant not shown, the shaft 60 may be monobloc instead of being made of two parts. According to another variant not shown, the winders 70 may be integrated with the shaft 60, or the installation 1 may be devoid of winders 70. The cables 56 are then directly wound on the shaft 60.

Whatever the embodiment of the invention, the assembly method of the installation 1 comprises a step of mounting the motor assembly 20 + 30 in the box 10 by pivoting R1 and clipping, and not by translation along the X10 axis. In addition, the technical characteristics of the various embodiments and variants mentioned above may be all or some of them combined with each other. Thus, the installation 1 and its assembly method can be adapted in terms of cost, ergonomics, functionality and performance.
