Definitions

  • the present invention will find its application in the field manually operated shutters.
  • roller shutter drive mechanism Insofar as the user will act directly on the roller shutter drive mechanism, nothing limits the torque likely to be printed on this mechanism if not the force available to the user himself. Also, it may be that actuating the roller shutter somewhat brutally, it may be damaged.
  • 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 canted 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 torque likely to be transmitted through the training cord on the shaft on which the pulley depends on the coefficient of adhesion therefore, friction, existing between this pulley and the crown. It is, by therefore, very difficult to precisely predefine the torque likely to be transmitted to the shutter drive tree rolling. In addition, it is likely to vary over time, depending on the wear rate of the friction ring. We will also notice that this coefficient of friction depends more particularly the axial forces exerted by the pads of the elastic washers. These axial forces are also caused to change over time.
  • 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 cooperate with reservations, provided for this purpose, on one side of the pulley.
  • the elastic blades in case the torque exerted on this pulley, by through manual training means, came to exceed a predetermined value, the elastic blades, at through their configuration, escape from their respective reservations allowing freewheeling at least a quarter turn of said pulley. In fact, said elastic blades again engage elastically in the following notches of the pulley allowing it to train the training tree provided, of course, that meanwhile, the resisting torque, with respect to the sense of control rotation has decreased.
  • the subject of the present invention is able to meet the requirements of the point view of the very design of a drive device disengageable manual for rolling shutter. More specifically, the device is simple in construction while being reliable, ie capable of training with a couple determined and constant over time.
  • the invention as defined in the claims, meets these criteria and consists of a device cord or similar drive for roller shutters, comprising a pulley around which is wound, at at least partially, said cord, this pulley being mounted secured in rotation on a drive shaft engaged with the winding shaft of the roller shutter deck, in particular through a reducing mechanism, a mechanism torque limiter being provided capable of ensuring the disengagement of pulley drive beyond a resistant torque determined produced by the winding shaft, this mechanism torque limiter consists of an integral intermediate hub in rotation of the drive shaft, on this hub being rotatably mounted the pulley, which is provided training means engaged with means complementary associated with said hub these drive means and the additional drive means being provided for elastic in nature and capable of bending under the effect resistance to determined training, to authorize the free rotation of the pulley relative to the intermediate hub.
  • the pulley is in the form of a crown in the internal bore of which the hub is housed intermediate, the training means associated with this pulley being defined by at least one elastic blade extending through this bore so as to cooperate with the toothing of a star wheel associated with the intermediate hub and corresponding to additional training means.
  • the present invention relates to the field of roller shutters and to particularly relates to a drive device 1 with cord 2 or the like.
  • This drive device 1 comprises a pulley 3 around which is wound, at least partially, 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 can 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 efforts.
  • 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 torque greater than a given value which would result in damage the roller shutter.
