Definitions

  • the present invention relates to devices for actuating movable members such as the windows of motor vehicles. It relates more particularly to actuation devices of the type comprising a rotary drum on which is wound a flexible element working in traction and in thrust.
  • actuating devices use steel cables as a flexible element. To prevent decohesion of the cable during pushing operation, and also to reduce friction between this cable and the drum casing and / or between this cable and its guide channel under the same conditions, it is necessary to surround the cable a plastic sheath.
  • the object of the invention is to provide an actuating device making it possible to significantly reduce the size of the drum as well as the weight of the entire device without hampering the attachment of the movable member to the flexible element.
  • the invention relates to an actuating device of the aforementioned type, characterized in that the flexible element is a plastic tape with a constant full rectangular section.
  • the Applicant has found that, surprisingly, by means of a suitable choice of the plastic material of the ribbon, the latter can have mechanical properties substantially equivalent to those of a steel cable with a large dimension equal to the diameter of this cable.
  • the actuating device can in particular be of the disc-shaped drum type having on one side a groove in the general shape of a spiral, as described in patent FR 80 22013 of the Applicant and in its certificate of addition FR 81 08874.
  • the space requirement is particularly reduced if the ribbon is received in a groove of the drum of conjugate section, the large dimension of this groove being its axial dimension.
  • the stresses to which the flexible element is subjected are on the one hand the useful tensile or compressive stresses, on the other hand parasitic stresses due to the curvature. It is therefore necessary to dimension the flexible element for the sum of these constraints, which oversizes its anchoring ends, which are rectilinear.
  • the device of the invention makes it possible to take advantage of this oversizing by the fact that at at least one of its ends, the strip has at least one hole in which is inserted a transverse anchoring pin on the drum or on the movable member, this pin being received in a recess of this drum or this member. This gives a specific fixing method of the invention which does not generate constraints in the tape and which is economical and reliable.
  • the invention also relates to an automobile window regulator provided with an actuating device as defined above.
  • the actuator 1 shown in Figs. 1 to 4 is intended to equip a window lift for a motor vehicle. It comprises a plastic drum 2 housed in a metal casing 3 and is intended to move in two directions a bottom ice slider (not shown) suitably guided, by means of a flexible tape 4 of rectangular section.
  • the drum 2 has the general shape of a flat annular disc in one face 5 of which is hollowed out a groove 6 of section complementary to that of the ribbon 4, with its large dimension oriented axially.
  • This groove has the general shape of a spiral of reduced radial size described in the aforementioned patent FR 80 22013.
  • the inner periphery of the drum 2 has, on the side of the face 5, an internal toothing 7. At the intersection of the outer periphery of the opposite face 8 and the outer cylindrical surface 9 of the drum is provided a rolling track 10 to quarter circle section.
  • the casing 3 consists of a bowl 11 closed by a crimped cover 12.
  • the bowl 11 receives the drum, with the interposition of balls 13, interposed with the separating members (not shown), between its rounded angle 15 and the track 10.
  • the two contacts of each ball 13 are inclined at approximately 45 ° on the axis XX of the drum, so that the ball bearing thus formed is both a thrust bearing and a centering bearing for the drum in its casing.
  • the cover 12 has, at a point on its periphery, a projection 16 open circumferentially in the direction of exit of the ribbon 4. This projection extends radially over the entire interval occupied by the groove 6, opens at its origin in the plane of the cover. , on this groove, and gradually narrows, forming a tangential appendage 19 of the cover 12.
  • the bowl 11 has another tangential appendage 20 opposite the appendage 19. These two appendages end in two knurled jaws 21, 22. These, crimped one on the other (Fig. 4), enclose and firmly block a flexible guide tube 23, in plastic material, which may in particular, as shown, consist of the end part of the cable guide channel up to the bottom window cursor.
  • the tube 23 is free between the jaws 21, 22 and the groove 6 and is contained inside the projection 16; it ends with a bevelled edge 24 located roughly in the general plane of the cover 12 and therefore perpendicular to the axis XX of the drum 2 and close to the face 5 thereof.
  • the end of the tube 23 is forcibly threaded onto a rigid tubular reinforcing element 25 which, like the tube 23, has a rectangular internal section combined with that of the ribbon 4.
  • the free end of the element 25 forms a beak 26 which penetrates in the throat 6.
  • the ribbon 4 is full, of constant rectangular section, with smooth faces. It consists of a plastic material with high mechanical properties, which can in particular be a drawn polyester.
  • An example of such. ribbon is the ribbon sold commercially by the governing du Pont de Nemours under the name "EPS tape DYMETROL", an appropriate section being 6 x 1.8 mm. This tape has a tensile strength of 30 kg / mm 2 , with an elastic limit of 10 kg / mm 2 .
  • the ribbon 4 is anchored by one end, in a manner which will be specified later, to the interior end of the groove 6. It is inserted into the groove, of which it exactly fills the section by being flush with the face 5 of the drum 2. When it is fully wound, it follows the groove 6 to a point close to the outer end of the latter and the entrance to the projection 16, point where it begins to exit from the groove 6 on edge to penetrate the reinforcing element 25 (Fig. 2). As seen in Fig. 2, the cover 12 is curved near the projection 16 to allow this exit of the ribbon 4. Then the ribbon 4 passes through the tube 23 and the guide channel which extends the latter and is anchored at its other end to the bottom window cursor.
  • the drive shaft 27 of the device 1 is guided parallel to the axis XX by two bearings 28, 29 provided in aligned bosses of the bowl 11 and of the cover 12.
  • the shaft 27 carries a pinion 30 in engagement with the toothing 7 of the drum, as well as a known mechanism 31 of the "auto-lock" type which is housed in an attached boss 32 of the cover 12.
  • the shaft 27 protrudes out of this boss to be connected to an actuator not shown.
  • the ribbon 4 working in compression does not tend to flame until the moment it begins to come out of its throat. Consequently, over almost three quarters of a turn, the cover 12 can practically be eliminated, or at least largely perforated to further lighten the device.
  • the hood openings can then be fitted with very light plastic covers, to protect against dust and other impurities.
  • FIGS. 5 to 8 to avoid shifting the strip 4 on edge when it leaves, it is possible to use a reinforcing element 25A twisted by a quarter turn, as illustrated diagrammatically in FIGS. 6 to 8.
  • the large dimension of the tube 23 in the jaws 21, 22 is then no longer parallel but perpendicular to the axis X-X.
  • an additional element 33 for guiding the tube 23 can be provided in the casing 3, between the element 25A and the appendix 20.
  • Figs. 9 and 10 illustrate the method of anchoring the ribbon 4 in the inner end of the groove 6, it is possible to anchor this ribbon on the slider in the same way.
  • the end of the strip is straight and has three holes 34 close to each other, located in a local enlargement 35 of the groove 6 which extends only over part of the depth thereof from the face 5 of drum.
  • a comb 36 with three teeth 37 complementary to the holes 34 is engaged in these holes and is inserted axially in the enlargement 35, the shape of which it follows. It is clear that this anchoring does not in itself create any constraint in the ribbon.
  • the size of the holes 34 is such that the remaining section is sufficient to withstand the stresses of thrust and traction; this is made possible by the fact that the end of the ribbon thus anchored is straight and is therefore not subject to additional stresses due to the curvature.
  • the ribbon 4 can be armed with one or more longitudinal metal wires.
