Definitions

  • the invention relates to an operating mechanism and to a closure or sun protection system comprising such a mechanism.
  • Closure installation means doors, gates, shutters, grilles and equivalent materials.
  • a mechanical or electrical drive member to rotate, around its main geometric axis, a winding shaft for a shutter screen of an opening , or a force transmission member, such as a strap, associated with such a screen.
  • Winding mechanisms comprising compensation springs are known, for example, from FR-A-2,743,107 , from DE-A-296 05 670 or JP-A-2000-234485 .
  • a tubular drive motor and, on the other hand, compensation springs, these springs and this motor to be put in place in the winding shaft on the site of use of the installation, whereas the conditions of work of the installer are sometimes precarious, in particular because of a accessibility in height limited.
  • many parts must be provided to install, on the one hand, the compensation spring and on the other hand, the motor inside the winding shaft, which increases the known facilities.
  • JP-A-11-101077 It is also known to JP-A-11-101077 to realize a control mechanism of a roller shutter in which a spring is fixed on a motor and on a transmission element associated with a clutch. The torque exerted by the spring is transmitted to the winding shaft of the shutter.
  • the invention intends to remedy more particularly by proposing an operating mechanism which comprises at least one compensating spring and which can be set up easily, while its cost price is more attractive than that of the known compensated mechanisms.
  • the invention relates to a mechanism for operating a closure or sun protection system comprising a drive member for rotating a winding shaft for a shutter screen and at least one compensation spring.
  • the weight of this shutter screen in which the drive member is secured to a bracket and the spring is mounted around a housing of the drive member and belongs therewith to a sub-frame. assembly adapted to be at least partially introduced unitarily within the winding shaft.
  • This mechanism is characterized in that a first end of the spring is kinematically connected to a first end of the housing which is opposite to the console, while its second end is secured to a first ring mounted free to rotate around a second end of the housing which is closest to the console, the first ring being adapted to be rendered directly integral in rotation with the winding shaft when the subassembly is in place in the shaft.
  • the drive member which may be an electric motor
  • the compensation spring can be manipulated and set up in a relatively simple operation, which facilitates the work of the installer, decreases the mounting time and reduces the number of accessory parts needed.
  • the invention also relates to a closure or sun protection system which comprises an operating mechanism as precisely described. Such an installation is easier to implement and more economical than those of the state of the art.
  • the installation partially represented figures 1 and 2 is not according to the invention. It comprises a mechanism 1 for winding more or less an apron T around a geometric axis X-X ', this to close more or less an opening O formed in the masonry of a building.
  • the mechanism 1 comprises a shaft 2 whose central geometric axis coincides with the axis X-X 'and which is supported relative to the building structure by means of a bracket 3 forming a bearing.
  • a drive member 4 is provided for rotating the shaft about the X-X 'axis, as shown by the arrow R at the figure 2 .
  • This member comprises an electric motor 41 and a gearbox 42.
  • the output shaft 43 is noted of the member 4 and 44 its housing inside which are housed the elements 41 and 42.
  • a compensation spring 5 is provided to compensate the torque exerted by the weight of the deck T about the axis X-X '.
  • This spring is a torsion spring disposed helically around the housing 44 of the member 4.
  • the housing 44 is provided with a lug 45 around which is anchored a first end 51 of the spring 5 which is shaped in a loop.
  • the second end 52 of the spring 5 is introduced into a housing 62 formed in a drive disk 6 provided to be secured in rotation with the shaft 2 by any appropriate means, for example by riveting.
  • the disc 6 is provided with a central opening 61 of section adapted to the section of the shaft 43, so that the disc 6 is integral in rotation with the shaft 43.
  • a spacer ring 7 is provided for centering the housing 44 in the shaft 2, with the possibility of rotation.
  • the elements 3 to 7 constitute a subassembly 10 which can be partially introduced, in one operation, inside the shaft 2, as represented by the arrow F 1 .
  • the member 4 and the spring 5 belong to the assembly 10 and are placed in the shaft 2.
  • L 5 is the length of the spring 5 taken in the direction of the axis X-X '.
  • L 4 is the length of the member 4 taken in the same direction. The length L 5 is less than the length L 4 and the spring 5 does not project substantially beyond the casing 44, which gives the subset 7 a compact and monolithic character simplifying its handling and allowing time savings by installation.
  • a rotation R of the shaft 2 induces a corresponding rotation of the disc 6 and a change in the tension of the spring 5, since its end 52 rotates about the axis X-X ', while its end 51 remains fixed relative to to the housing 44 which is itself fixed relative to the axis X-X '.
  • the mechanism 101 of this embodiment is also centered on an axis XX 'and comprises a shaft 102 for winding a deck T, this shaft being supported by a console 103 and receiving a drive member 104 comprising an electric motor 141 and a gearbox 142.
  • a spring 105 is mounted around the housing 144 of the member 104, this spring being secured by its first end 151 of a lug 145 provided on the casing 144.
  • a spacer ring 107 is disposed around the housing 144, near the bracket 103, with the possibility of rotation, and allows a relative centering of the elements 102 and 104.
  • a ring 108 is rotatably mounted around the end 144a of the housing 144 opposite the console 103, this ring 108 being provided with a central opening 181 whose section is such that it can be rotated by the output shaft 143 of the member 104.
  • the second end 152 of the spring 105 is fixed by any appropriate means on the ring 108, for example by cooperation of shapes, clipping, gluing or welding.
  • a drive disk 106 is fixed inside the tube 102 during its manufacture and is provided with an opening 161 for receiving the shaft 143, the section of the opening 161 allowing a drive in rotation of the disk 106. from the tree 143.
  • the elements 103 to 107 and 108 constitute a subassembly 110 which may be partially introduced into an operation inside the tube 102, as represented by the arrow F 1 at the figure 3 .
  • the length L 105 of the spring 105 parallel to the axis XX ' is smaller than the length L 104 of the member 104 parallel to this axis.
  • the mechanism 201 of this embodiment comprises a drive shaft 202 of an apron T to close more or less an opening O.
  • This shaft 202 is supported by a console 203 immobilized relative to the masonry of the building.
  • a drive member 204 comprises an electric motor 241 and a gearbox 242 disposed within a cylindrical casing 244 of circular section such as the housings 44 and 144.
  • This shaft 243 is the output shaft of the member 204. This shaft 243 is intended to be introduced into an opening 261 of a drive disc 206 fixedly mounted inside the shaft 202.
  • a spring 205 is mounted around the housing 244 and immobilized in rotation thereon by clamping its first end 251 on a frustoconical ring 209, itself immobilized on the end 244a of the housing 244 opposite the bracket 203.
  • Another ring 208 is mounted around the housing 244, at its end 244b closest to the console 203, the ring 208 being rotatable around the end 244b.
  • the ring 208 is, moreover, provided with a frustoconical surface 282 for receiving and jamming the second end 252 of the spring 205.
  • the ring 208 is also provided with a plurality of radial projections 283 intended to be each engaged in a notch 223 formed at the end 221 of the tube 202.
  • the elements 203 to 205, 208 and 209 constitute a subassembly 210 that can be introduced in one operation, represented by the arrow F 1 on the figure 5 , inside the tube 202, this subassembly for performing the drive functions of the tube 202 and compensation, as the subsets 10 and 110 of the first and second embodiments.
  • the shaft 243 engages inside the opening 261, while the projections 283 engage in the notches 223.
  • the ring 206 is mounted on the shaft 243 before the subassembly 210 is introduced into the tube 202, which avoids a subsequent adjustment of the relative orientation of the rings. 206 and 208.
  • the same way of proceeding can be used with the mechanisms of the first and second embodiments.
  • This embodiment has the particular advantage that, in the configuration of the figure 5 of the subassembly 210, which corresponds to its storage configuration before installation in an installation provided on a building, the torque exerted by the spring 205 between the rings 208 and 209 is not transmitted to the shaft 243.
  • a means of immobilization in rotation of the ring 208 relative to the housing 244 this means may be a key 211 as shown in phantom at the figure 5 . Any other means of immobilization can however be envisaged, for example a fastening by screwing.
  • the position of the ring 208 can be adjusted before its immobilization with respect to the housing 244, so that the compensation force exerted by the spring 205 substantially corresponds to the compensation force to be exerted to compensate for the maximum weight of the deck. T, that is to say its weight in the closed configuration of the opening O.
  • This maximum torque is not transmitted to the shaft 243, and by the same to the gearbox 242, this gear can be dimensioned taking into account because when the subassembly 210 is in place in the shaft 202, the weight of the deck T and the force of the spring 205 compensate approximately.
  • the gearbox 242 may therefore be smaller and lighter than the gearboxes of the known installations, this making it possible to make a substantial gain in the cost price of the mechanism 201.
  • the length L 205 of the spring 205 is substantially shorter than the total length of the member 204.
  • a mechanism according to its principle can also be equipped with a safety device as described in the French patent application No. 2,837,866 .
