  • Apparatuses comprising a drive pulley device, moved manually or mechanically, which scrolls a cable without storing it.
  • this device the tightening of the cable in the groove of the pulley is exerted by the pressure of a pivoting member, a roller or a series of rollers for example, this pressure being applied either by the effect of springs, or by the effect of deflection exerted by the load.
  • a pivoting member a roller or a series of rollers for example, this pressure being applied either by the effect of springs, or by the effect of deflection exerted by the load.
  • patent FR-A-1 389 136 describes a traction device allowing the lifting and lowering of a load.
  • This device comprises a pulley driven in rotation, a cable which runs on the periphery of this pulley and to one strand of which the load is fixed, and a chain of pressure rollers which is constrained, under the effect of the load, to press the cable on the peripheral surface of the pulley.
  • the peripheral groove of the pulley has a cross section in V to receive the cable which is pressed by the rollers of the chain.
  • the object of the present invention is to remedy to this drawback and proposes for this purpose a drive device which is constituted by the combination of a pulley, clamping and guiding members, and a flexible flat link to which the load, the pulley and the clamping and guiding members being designed to allow the driving of such a flexible flat link, strap or flat belt for example, taking into account the constraints specific to the use of such a link, constraints different from those encountered for driving a round section link, such as a cable, in particular less flexible than a flat link and, in particular, a strap.
  • the invention applies to the different possible embodiments of known devices, according to the two main methods of tightening the cable in the pulley groove, that is to say constant pressure by springs and pressure by return of a deflection of the load.
  • the pressure of the flexible link against the peripheral surface of the pulley can be applied by a single pressing member or by a series of pressing members arranged at the periphery of the pulley.
  • these can be actuated either by separate springs applied respectively to each of them, or by a force applied at a single point, itself transmitted to said pressing members or by a bogie system , or by a connection between said pressing members by means of a series of links forming a chain with these pressing members.
  • a separate spring or springs for each pressing member can be combined with a deflection action, said spring or said springs then playing a permanent pre-tightening role.
  • the action of the springs can be replaced by an elastic deformation of the surface peripheral of the pulley and / or of a pressing member whose axis is then fixed.
  • means can be provided for retracting the axis of the pressing member during the introduction of the flexible link.
  • said chain is subjected to tensile stress, at its end situated on the side of the soft strand of the link, from a deflection member disposed on the path of the strand charged with the link, and in a direction forming an angle at most of 90 ° with the radius of the pulley passing through the end point of said chain to which this traction applies.
  • the arrangement of the pressing member or pressing members is arranged so that the winding arc of the link on the pulley covers the greatest possible radial angle.
  • the drive system can also be designed for winding the link along an S-shaped path around two pulleys, the pulley of which is located downstream from the load and is fitted with the pressure and guidance devices mentioned above.
  • the device for driving a load comprises a pulley driven in rotation, a flexible link running on the periphery of said pulley and to one strand of which the load is fixed, and constrained means for pressing the link on the peripheral surface of the pulley, said means being mainly constituted by at least one roller and the peripheral surface of the pulley being profiled to receive the winding of such a link by cooperating with a counter-profile, and it is characterized in that the link is flat and in that the counter-profile corresponds to the profile of the peripheral surface of the pulley and belongs to the peripheral surface of the pressure roller (s).
  • the peripheral profile of the pulley can thus be flat with lateral guide flanges, or concave in an elliptical shape or a very flat V shape with a flat bottom or bottom formed by an arc tangent to the two branches of the V, or conversely be convex in one of the forms mentioned above for the concave profile.
  • the peripheral profile of the pressure member (s) being the counter-profile which corresponds to the peripheral profile of the pulley, so as to ensure correct cooperation of the pulley, the flat link and the pressing member.
  • peripheral surfaces of the pulley and / or of the pressing member (s) may be coated with a substance chosen to improve their adhesion to one and / or the other of the two flat surfaces of the link, depending on the material of which it is made. this. Furthermore, the peripheral surface of the pulley and / or of the pressing member or of the pressing members may include a system of roughness such as knurling.
  • the configuration and flexibility of the flat link require the fitting of appropriate guiding means in order to ensure a course correct soft strand of this link during the upward movement or traction of the load, and especially in order to avoid its untimely winding around the pulley training outside its normal course. Similarly on the side of the strand loaded with the link, if the load ceases to apply to it.
  • the invention provides a guide which covers the peripheral part of the pulley not covered by the winding of the flexible link, at least on the side where the soft strand must leave the peripheral surface of the pulley, so that the strand leaving this surface is thus deviated out of the circular path that the pulley tends, by its movement, to impress on it.
  • the guide has a curved face conforming to the shape of the periphery of the pulley on its part not covered by the winding of the link and extending from one point to the other of the two points of insertion of the link. on the pulley.
  • the curved face of the guide can be extended, at each of its ends, by a lateral face arranged to orient the movement of the link so as to print the desired path inside the device.
  • a fourth face can join the ends of the two preceding ones according to an appropriate conformation, and the guide thus formed can be constituted either by a full or partially full piece, or by a plate folded in a suitable way.
  • the guide can be held in place in a position of extreme proximity to the pulley arch that it covers, and it then has a curvature concentric with that of the pulley.
  • the guide can also be applied in contact with the pulley, by a spring acting on the face of the guide located opposite the pulley and whose action can be adjusted.
  • the curvature of this face is of a radius substantially less than that of the pulley, so that only its two ends are in frictional contact with the pulley.
  • Complementary devices can guide the movement of the guide under the effect adjustment of the above spring, this adjustment being able, if necessary, to remove the contact between the guide and the pulley.
  • the face of the guide located opposite the pulley can be made of an elastic material ensuring flexibility of this face under the action of the spring mentioned above.
  • a pair of rollers whose axes are parallel to that of the pulley, can be associated, outside the pulley, with the soft strand of the link as well as, optionally , to the load carrying strand in case it ceases to apply to this strand.
  • Each of these pairs can be completed by a pair of rollers located in their vicinity, whose axes are perpendicular to those of each pair above, so as to frame the faces of the flat link delimiting the thickness thereof.
  • a simplified embodiment of this device only one of the rollers of the pair or pairs of rollers concerned is thus motorized, while the other roller is applied against the link by an adequate pressure means, so as to maintain contact constant between the link and the motorized roller.
  • the soft strand of the link can be recovered by a winding system incorporated in the device and provided with a spring system which constantly urges it in the winding direction, regardless of the direction of rotation of said winding system.
  • this arrangement does not make it possible to maintain the tension of the strand loaded in the event of the suppression of the application of the load in the direction of descent.
