Definitions

  • the invention relates to a cord or analog for rolling shutter, according to the preamble of claim 1.
  • the present invention will find its application in the field manually operated shutters.
  • such a compensating device is usually has the form of a helical spring arranged inside the winding shaft which comes out is gradually put under stress during the deployment of the apron so as to allow it to restore its energy to time to open the roller shutter again.
  • this pulley rotatably mounted on a shaft drive, this pulley being chamfered at the periphery and on each of its sides so as to define, on its periphery, inclined walls generating friction zones and slip for a crown.
  • This is defined by two annular flanges made integral with a friction ring cooperating with the inclined walls of the pulley. More particularly, this friction ring is defined by elastic washers secured to the annular flanges and bearing, by means of skids, on said overhanging walls. The assembly is pre-stressed so that said elastic washers exert, by through their skate one component force at a time radial and axial on the pulley.
  • the drive pulley comprises, at level of its periphery, a succession of semicircular reservations for receiving the spherical elements of a Ball drive chain.
  • Said pulley is rotatably mounted on the shaft training, the latter being carried out at across a plate with elastic blades.
  • this plate is rotatably mounted on said shaft drive and has, radially, four blades elastic whose ends come to cooperate with reservations, provided for this purpose, on one side of the pulley.
  • the subject of the present invention is able to meet requirements from the point of view of the very design of a manual drive device disengageable for rolling shutter. More specifically, the device is simple in construction while being reliable, that is to say capable of providing training with a couple determined and constant over time.
  • the additional drive means are defined by a star wheel associated with the intermediate hub and having teeth with which the blade cooperates elastic of said drive means.
  • Figure 1 is a schematic representation, in elevation and in section along I-I of Figure 2 of the drive device according to the invention
  • Figure 2 is a schematic representation in section along II-II of Figure 1.
  • the present invention relates to the field of roller shutters and to relates, in particular, to a drive device 1 to cord 2 or the like.
  • This drive device 1 comprises a pulley 3 around which is wound at least partially, the said cord 2, this pulley 3 being mounted integral in rotation on a drive shaft 4 engaged with the winding shaft 5 of the apron of said rolling shutter.
  • this pulley 3 it is very common for this pulley 3 to be in taken with the winding shaft 5 via a reduction mechanism 6 which has been shown so shown diagrammatically in FIG. 1, taking into account, in fact, that this reducing mechanism 6 can adopt different forms of production.
  • This drive device 1 also includes a mechanism drive torque limiter 7 provided capable of ensuring the disengagement of the drive by the pulley 3 beyond a torque determined resistance produced by the winding shaft 5, the case if necessary through the reduction mechanism 6.
  • this torque limiting mechanism 7 consists in an intermediate hub 8 which is integral in rotation with the drive shaft 4.
  • this hub 8 is also rotatably mounted pulley 3, which is provided with drive means 9 engaged with means additional drive 10 associated with said hub 8, these drive means 9 and / or drive means complementary 10 being provided of an elastic nature so able to bend under the effect of resistance to training determined, to allow the free rotation of said pulley 3 relative to the intermediate hub 8.
  • the pulley 3 is in the form of a crown in the internal bore 12 in which the intermediate hub 8 is housed.
  • Quant the drive means 9 associated with the pulley 3, they are defined by at least one elastic blade 13 extending at through this bore 12 so as to cooperate with the toothing 14 of a star wheel 15 defined in the center of a groove peripheral 16 of said intermediate hub 8 and corresponding additional training means 10.
  • two 14A, 14B teeth of the teeth 14 corresponding to this star wheel 15 are defined suitable for take support on this elastic blade 13 so as to allow the drive of this intermediate hub 8 by through the pulley 3.
  • said drive means 9 may consist of two elastic blades 13, 13A arranged symmetrically with respect to a diametrical plane 17 of the pulley 3, each of these elastic blades 13, 13A engaging diametrically opposite with the teeth 14 of the wheel star 15, this for a better distribution of forces.
  • the present invention makes it possible to remedy, advantageously, to the aforementioned problem in the sense that through of the torque limiting mechanism 7 it is impossible, at a user, to communicate to the winding shaft 5, if applicable if necessary through a reduction mechanism 6, a couple greater than a given value which would result in damage the roller shutter.
