Definitions

  • the present invention relates to a device for closing a sliding member, in particular a sunroof of a motor vehicle, of which a transverse rod carrying a motor pinion is engaged, engaged with a fixed longitudinal rack.
  • the engine force in general, remains constant and moderate during most of the race and increases sharply during the last centimeter (s), that is to stretch the fabric when it acts of a flexible roof, that is, in the case of a rigid roof, to compress seals.
  • the object of the invention is to provide a closing device making it possible to significantly reduce the torque necessary to obtain the final closing force and, at the same time, to lock the sliding member in the closed position by relieving the members of the reducer.
  • the subject of the invention is a device of the aforementioned type, characterized in that it comprises a toothed element fixed or articulated at the front end of the rack and the teeth of which have a curved front part and a rear part. practically rectilinear, and means for forcing the pinion to remain in engagement with said curved part at the end of the closing stroke.
  • the toothed element comprises, at least in its curved part, a ramp of the same profile on which a roller is supported by the rod.
  • the device 1 shown in Figs. 1 and 2 is articulated at its rear end, by an axis 2, at the front end of a rectilinear fixed rack 3 having its teeth 4 on its upper face.
  • This device essentially comprises a toothed element 5, a hook 6, 17 and a ramp 7.
  • the element 5 is a small rack whose teeth 8, in the rest position of FIG. 1, extends over the same width the toothing 4 of the fixed rack 3.
  • the toothing 8 has a rectilinear rear part 9 whose teeth have flat sides, and a front part 10 in the form of a toothed wheel sector extending over a little more than a quarter of a circle, directed downwards, the teeth of which have rounded sides.
  • the base 11 of its first tooth is knocked down.
  • the tooth 12 located at the junction between the parts 9 and 10 of the toothing 8 has a flat rear face and a curved front face.
  • the hook 6, 17 is constituted by a rectilinear plane lever 6 attached to one side of the element 5.
  • the lower end of this lever journals on an axis 13 passing through the center of the quarter circle 10.
  • a spiral spring 14 stretched between the underside of the element 5 and a stud 15 of the lever 6 and wound around the axis 13 normally maintains this lever in abutment, in a vertical position, against a stop 16 which projects laterally on the element 5.
  • the part of the lever 6 which projects above the toothing 8 has a notch 17 open towards the rear, the bottom of which is a semicircle centered vertically on the axis 13.
  • the ramp 7 is constituted by a plate plated and riveted against the lateral face of the element 5 opposite the lever 6; the upper edge of this sheet forms a rolling ramp parallel to the toothing 8 but projecting slightly relative to the latter, preceded by an ascending collision part 18 8 and consisting of a flat rear part 18 b and d 'a front part 19 in quarter cylinder.
  • the device 1 is used at the front end of a sunroof for an automobile, under the following conditions illustrated in FIGS. 3 and 4.
  • the sunroof is secured to a transverse rod 20 guided in horizontal translation, by means not shown, in a plane P passing through the center of the notch 17; the bottom thereof has the same diameter as the rod 20.
  • This rod is connected without sliding to the output member of the reduction gear of a motor for actuating the sunroof (not shown).
  • a pinion 21 On each of its ends is wedged a pinion 21, for example of plastic material, the teeth of which have curved faces and which is engaged with a longitudinal rack 3 fixed to the body of the vehicle.
  • Each rack 3 carries at its end an articulated device 1 as described above.
  • each pinion 21 is engaged with the corresponding rack 3, as shown in phantom in FIG. 3. Then this pinion rolls in direction f on the part 9 of the element 5 until the rod 20 is received, at point A, in the bottom of the notch 17 of the hook 6, 17.
  • the pinion 21 continues to be driven in rotation in the fl direction by the rod 20, whose axis is forced to remain in the plane P. There then occurs a rolling of the pinion on the curved teeth 10 with, simultaneously, a rotation of the element 5 upwards around the axis 2 and a downward rotation of the hook 6, 17 relative to the element 5, against the spring 14.
  • the device 1 In the position of FIG. 4, the device 1 is self-locked so that the traction force F exerted in the plane P. This force is almost entirely supported by the support of the roller 24 on the part 19 of the ramp 7. It is not necessary to continue to exert a torque on the rod 20.
  • part 10 of the toothing 8 can be given a length slightly greater than that over which the closing force increases, that is to say a length of approximately 15 mm.
  • the curvature of this part 10 ensures a significant reduction in the force, so that the increase in engine torque to be provided is only about half of what it would be if the rack 3 extended to the point B.
  • the motor rotates the shaft 20 and the pinion 21 in the direction f opposite to the f i.
  • the pinion then rolls on the part 10 of the toothing 8 causing the element 5 to return to its rest position in FIG. 3, defined by its coming into abutment against the support 3 8 of the rack 3.
  • the spring 14 causes the lever 6 to return to the vertical position against the stop 16.
  • the pinion 21 then rolls successively on the part 9 of the toothing 8 and on rack 3.
  • the roller 24 can have the diameter of the pitch diameter of the pinion 21 and roll on a ramp along the pitch curve 25 of the toothing 8.
  • the roll 24 can be wedged on the rod 20, or made of material with the pinion 21, since it rotates at the same speed as the latter while rolling on the ramp. This fastening of the roller-pinion can moreover be provided in all cases, since a bearing with sliding of the roller 24 on the ramp 7 does not present any serious disadvantage.
  • the lever 6 could be suspended, freely rotatable, on the rod 20, possibly with a return spring against a stop of a bearing for guiding this rod, with the notch 17 directed forward and hooking a stud provided on the element 5 at the location of the axis 13.
  • Other means can also be provided to force the pinion 21 to roll on the part 10 of the toothing 8, for example a sheet fixed on the lateral face of the element 5 opposite the ramp 7 and provided with a circular sector slot open towards the rear at the location of the notch 17 in FIG. 3.
  • the assembly constituted by the element 5, the ramp 7 and possibly such a split sheet can be molded in one piece from a suitable material.
  • the fixed rack 3 often has a slight curvature in a vertical plane to follow the shape of the roof of the vehicle.
  • the part 9 of the element 5 has a similar curvature.
  • the element 5 can be rigidly fixed to the rack 3 in the position of FIG. 1, and the rod-pinion 21 assembly can move in a vertical slot provided in the guide bearing, this bearing being guided in horizontal translation.
  • the invention can be applied to the closing of other sliding members, in particular those, such as hermetic doors, which require increased effort at the end of the race.
