Definitions

  • the invention relates to the field of sun shades, and in particular venetian blinds with parallel blades, foldable and steerable.
  • These venetian blinds can be operated by means of a motorization device, housed in a support box, to which are folded the blades in a full opening movement of the blind.
  • the blades are themselves supported by cords or ribbons and the motorization device also manages the winding of cords or ribbons at the box.
  • the document EP-A-1321623 describes elastomeric supports reported between the feet of a motor and the free edges of the U of the box, or arranged at the ends of a support ring of the engine. These serve to absorb the vibrations possibly transmitted to the box. It is also known from this same document to maintain the box vis-à-vis the support structure, for example a wall or a ceiling which is suspended from the blind, with support hooks, enclosing the box. These hooks are provided with flexible tabs so as to insert the box U. Several hooks support the box along its length.
  • the document DE-U-202007010766 describes a device for holding an engine inside a box that does not require the use of a tool.
  • the holding device comprises in particular a tongue provided with folded edges at its ends. These flanges are housed under the curved edges of the U-shaped casing. By means of an eccentric lever, the tongue plates the motor in a cradle in the bottom of the box and also makes it possible to press against the box the ends of the cradle. engine support.
  • the document DE-U-202008002359 describes a similar device, for which the engine support cradle comprises handles coming to rest on the curved edges of the box. These handles cooperate with a hook for holding the motor in the rail, this hook comprising holes in which the handles of the cradle are embedded.
  • the document CH-A-691 131 also describes a device for holding an engine inside a box.
  • the motor is equipped at its ends with elastomer elements, to prevent the propagation of noise.
  • the holding device comprises in particular a flange in two parts assembled by screws and maintaining axially and radially the motor and the elastomeric elements.
  • NL-A-6 400 653 or US-A-4,949,926 to use two-part consoles, comprising a support and a locking member, for fixing the rail of a blind on a supporting structure.
  • these materials must allow the installation of the rail after fixing the support on a supporting structure, such as a ceiling or a wall.
  • the locking element is supported on this support, with the possibility of pivoting as in NL-A-6 400 653 , or sliding against a spring as in US-A-4,949,926 .
  • These movements require games, to the point that the edges of the box can vibrate transversely, including after mounting on the consoles.
  • vibrations can propagate on the free edges of the box, between two consoles, and the number of consoles used to fix the rail on the supporting structure can not be increased without increasing the exposure time.
  • the invention therefore proposes a device for stiffening the box to reduce or prevent the problems mentioned above.
  • the stiffening of the box is obtained by the combined action of the first contact element and the second contact element which can enclose between them certain parts of the box, which immobilizes these parts and provides a permanent stiffening of the box .
  • This immobilization can take place independently of the distribution of the support means along the box.
  • the number of stiffening device can be adapted to the vibratory behavior of the box, without increasing its exposure time. The propagation of vibrations in the box is thus avoided to a large extent.
  • the invention also relates to a receiving box of a motorization device for the operation of a blind, in particular a Venetian blind, this box having a U-shaped section.
  • This box is characterized in that it is equipped with less a device as mentioned above which allows its stiffening, along an axis perpendicular to a longitudinal axis of the box.
  • the figure 1 shows schematically a sectional view of a motorization device 1, comprising a box (or rail) 10 in which is placed a motor (not shown) and a winding tube 3, according to the prior art.
  • the box 10 has a substantially square section forming a U, the edges 11, 12 are curved so as to stiffen this section.
  • the motor or the winding tube are held in place by a clamping piece 5, housed inside the U-shaped section and partly under the curved edges 11 and 12.
  • This clamping piece serves mainly to maintain the motor and / or winding tube clamped against the bottom 10a of the box 10.
  • the means conventional clamping devices are not shown.
  • a shim 6 elastomer may be present between the box and the various elements of the motorization device (flange, motor, tube).
  • FIGS. 2 and 3 show in perspective a first embodiment, according to the invention, a device 30 for stiffening a box 10, the latter being partially shown.
  • the figure 4 represents this first exemplary embodiment in end view.
  • the stiffening device does not participate in maintaining and tightening the motor or the winding tube in the box, but this alternative is possible.
  • Fasteners comparable to those, 21, of the figure 1 but not shown, allow to immobilize the box 10 on a supporting structure, for example a ceiling. These fastening elements cooperate with a flange similar to the flange 7 of the prior art and are independent of the device 30.
  • the fasteners not shown are dedicated to mounting on the carrier structure and distributed along the rail according to its weight and its environment, for example the nature of the ceiling which may include beams and plaster.
  • One or more devices 30 are mounted on the box 10 at locations that may correspond to vibratory deformation bellies, that is to say zones of deformation of maximum amplitude, for example between two fixing flanges of the box to the supporting structure. Since the devices 30 are independent of the fixing elements, their number and their position along the longitudinal axis X-X 'of the box can be adapted according to the vibratory behavior of the box, without increasing the exposure time of the drive device.
  • the curvature printed at the free edges of the box allows to stiffen it
  • the longitudinal opening required for the insertion of the winding tube or the motor necessarily causes a fragility of the box conducive to the propagation of vibrations from mechanical transmissions of motor movement.
  • the stiffening device 30 comprises a first contact element 31 intended to cooperate with at least a portion of a surface 13 facing outwardly of a box 10, said outer surface, and a second contact element 32 intended to cooperate with at least a portion of a surface 14 facing the interior of the box, said inner surface.
  • the outer surface 13 extends, in particular, on the outside of the branches of the U formed by the cross section of the box 10.
  • the outer surface 13 and / or the inner surface 14 are not necessarily continuous, because of the presence of the curved edges of the box.
  • the device 30 also comprises clamping means 35 of the first element 31 and the second element 32 with each other.
  • the first contact element is in the form of an outer flange 31 comprising a median portion 31a and ends 31b and 31c folded relative to the median portion to be housed on either side of the box 10.
  • the outer flange 31 is directly in contact with the outer surface 13 of the box, on the vertical walls and / or on part of the curved edges of the box 11, 12 facing outwardly of the box.
  • the outer flange 31 can be placed on the casing 10 by elastic deformation, in particular the box itself. It is preferably tightly mounted on the box.
  • the outer flange supports in its middle part a part of the clamping means 35.
  • the not shown fastening elements are removably attached to the outer flange 31.
  • the second contact element is in the form of a flange 32 inside the box, comprising a median portion 32a and ends 32b and 32c folded to be housed under the curved and free edges 11 and 12 of the box when the latter is installed.
  • the folded ends of the inner flange 32 are themselves bent outwardly to form two tabs 32d, 32e for hooking the inner flange under the edges 11 and 12 of the box 10.
  • the inner flange 32 is directly in contact with the inner surface of the box, on the vertical walls and / or on part of the curved edges of the box facing inwardly of the box.
  • the inner flange 32 can be put into place in the box by lateral displacement, by rotation or by elastic deformation of the box 10 and / or the flange 32.
  • the inner flange supports, in particular in its middle part, a part of the clamping means 35. It is preferably tightly mounted on the box.
  • the flanges 31 and 32 may be made of plastic or metal.
  • the clamping means 35 consist, for example, of a screw and a nut, arranged on either side of the two median portions of the first and second flanges. They allow the bringing together of the two flanges vis-à-vis the other, so the tightening of the edges 11 and 12 of the box 10 between the flange 31 and the tabs 32d and 32c.
  • a counter nut 35a locks the means 35 in the clamping configuration.
  • the flanges can be clamped relative to each other in rotation.
  • the inner flange can be placed obliquely by the opening of the box and rotated relative to the outer flange, so as to clamp its folded ends against the inner surface of the box.
  • the clamping means then comprise a member for rotating the inner flange and / or an anti-loosening clip, avoiding the loosening of the inner flange under the effect of repeated vibrations.
  • stiffening devices 30 may be installed along the length of the box 10, as far as possible distributed equitably along this length, parallel to the axis X-X '.
  • the outer flange 31 comprises two shims 31 f and 31 g intended to bear, from above, on the edges 11 and 12 of the box. These shims can be made integrally with the flange 31 or be reported during assembly and before tightening. In the same way, curved portions 32f and 32g are created at the folded ends of the flange 32 and provided to bear on the portion of the edges 11 and 12 facing the inside of the box 10. These wedges can be rigid or elastic.
  • the inner flange 32 also includes a lateral abutment 36, making it possible to form a lateral bearing surface for the outer flange 31, during assembly and tightening of the elements 31, 32 and 35, and thus to position the flanges one compared to the other.
  • This lateral stop could alternatively be arranged on the outer flange.
  • the stiffening device 30 is independent of the not shown elements used for fixing the box 10 to the ceiling or on a wall.
  • the flanges 31 and 32 are respectively in contact with the outer surfaces 13 and inner 14 of the box 10 by means of elastomeric parts. More specifically, elastomer wedges 41b and 41c are interposed between the curved ends 31b and 31c of the flange 31 and the surface 13. Moreover, elastomer wedges 42b and 42c are interposed between the curved ends 32b and 32c of the flange 32 and the surface 14. It is noted that the wedges 42b and 42c have an L-shaped section, so that they also extend between the ends 32d and 32c and the curved edges 11 and 12 of the box 10.
  • the clamping means 35 may be of any type adapted to their functions, in particular a screw, a screw / nut assembly or a pivoting hook. On the figure 5 these clamping means are represented by a rectangular element and the two arrows F 35 represent the clamping force exerted on the flanges 31 and 32.
  • the figure 6 represents a third embodiment.
  • the references of the preceding figures are repeated and increased by 100 to designate similar elements.
  • the fixing device is independent of the elements not shown fixing the rail 10 to the ceiling or on a wall.
  • the outer flange 131 is formed of a central portion 131a and two ends 131b and 131c folded relative to the central portion to be housed on either side of the box 10. It also comprises fixed pads 131h and 131 i protruding from the middle portion of the outer flange opposite its ends 131b and 131c.
  • the inner flange 132 is formed of two independent portions 132i and 132ii. Each portion of the inner flange 132 is formed of an arm 132b, 132c whose end 132d, 132e is folded to be housed under the curved edges 11 and 12 of the box.
  • Each portion 132i or 132ii of the inner flange 132 can slide vis-à-vis the outer flange and be held tight against one of the fixed pads 131 h or 131 i, which represent the arrows F 135 .
  • the flanges 131 and 132 tightened pinch the curved edges of the box. This pinching can take place by direct contact between the flanges 131 and 132, on the one hand, and the box 10, on the other hand.
  • this nip can take place via elastomer wedges 141b, 142b, 141c, 142c.
  • the flanges 131 and 132 form a rigid connection with the box 10, in particular along an axis YY 'defined as in the first embodiment.
  • the arms of the inner flange 132 and the pads of the outer flange 131 namely the arm 132b and the pad 131 h on one side, the arm 132c and the pad 131 i on the other, are made to each have a clamping surface vis-à-vis each other when these flanges are assembled on the housing 10.
  • the clamping means 135b and 135c can be here consist of a screw and a nut, on the one hand and other two surfaces facing the two flanges. Tightening causes the portions 132i and 132ii of the inner flange 132 to move axially parallel to the axis Y-Y '. This clamping can affect either the two parts 132i and 132ii simultaneously or a clamping means per flange portion interior. Thus, the flange 132 pinches the curved edge of the box.
  • An alternative to this third embodiment is to use a one-part inner flange and a two-part outer flange.
  • the assembly is equivalent to that described above.
  • the stiffening device may comprise two independent flanges and preferably symmetrical, each forming a contact between an outer surface and an inner surface of the box on either side of the opening of the box. Clamping means ensures the connection between the flanges and also the contact with the different surfaces of the box.
  • the stiffening device 30 or 130 allows, like that of the first embodiment, to create a rigid connection between the free edges 11 and 12 of the box, without degree of freedom along the Y axis -Y. This is achieved by closing the U-section of the box by the stiffening device at selected locations along the box regardless of the position of the fasteners on the carrier structure.
  • the stiffening device 30 or 130 comprises at least one dynamic vibration absorber means as represented, with the references 51, 52 and 150, on the figures 5 and 6 .
  • This means of dynamic vibration absorber transforms the mechanical energy, vibratory type, into thermal energy.
  • This dynamic vibration absorber means comprises, for example, a piezoelectric element capable of generating an electrical voltage under the effect of a deformation or a constraint mechanical, connected to an electrical resistance.
  • the electrical energy produced is completely dissipated by the Joule effect in the electrical resistance.
  • a single composite material is used for producing the dynamic absorber means, having both piezoelectric and electrical resistance properties capable of simultaneously producing and dissipating electrical energy from mechanical energy. of vibration.
  • the compound material is arranged to be constrained in the space between the two flanges, as shown in FIG. figure 5 .
  • the dynamic vibration absorber means is simply glued to one of the flanges, as shown in FIG. figure 6 . It then works essentially in shear.
