Definitions

  • the present invention relates to a device for fixing a chairlift or a gondola or any other similar machine to a cable, of the type comprising a fixing part on the cable extending along the cable and having a surface bearing on which rollers are caused to roll.
  • Fixing devices of this type are currently already known. From patent FR-A-2276970, there is known a fixing device which comprises a fastener fixed to a cable and on which are provided rolling surfaces for rollers which extend in the direction of the cable and which has at their ends flat surfaces inclined towards the latter. Also known from US-A-3420189 is a fixing device, the fixing part of which on the cable comprises, at its ends, extensions and on which is provided a rolling surface for rollers, extending in the direction of the cable, these extensions being, in the direction of the cable, rounded and inclined in the direction of the latter. In these known fastening devices, each time a roller frees the fastener or the fixing part on the cable, there is a shock on the fastening device when the roller goes up on the rolling surface and a shock on the cable when the roller leaves this running surface.
  • the present invention aims to remedy these drawbacks and provides a fixing device whose structure makes it possible to avoid any impact of the rollers both in its part for fixing to the cable and on the latter.
  • the fixing device via a hanger of a gondola or chairlift on a cable moving on rollers, according to the present invention, comprises a fixing part which clamps the cable.
  • This fixing part comprises at its ends extensions and has a rolling surface extending in the direction of the cable and on which the rollers are caused to roll to cross it, this rolling surface being on said extensions inclined towards the cable .
  • each of said extensions further comprises at least one branch which extends laterally and along the cable and which provides a running surface or ramp which extends the running surface of said fixing part so that the rollers come or leave by tangential contact the rolling surface or ramp of the branches of said extensions, at their ends or in the vicinity.
  • each of said extensions comprises two branches which extend on either side of the cable, laterally and along the latter, these two branches providing said rolling surface or ramp extending the rolling surface of said fixing part.
  • the surface adjacent to the cable of said extensions and their branches is preferably provided concave in order to substantially match the shape of the cable.
  • the shape of the running surface of said legs corresponds, perpendicular to the cable, to the shape of the running surface of said fixing part.
  • the device for fixing a gondola or chairlift is generally constituted by a clamp. Consequently, the extensions to the present invention can be provided on the branches of this clamp.
  • the fixing device represented in FIGS. 1 and 2 and generally identified by the reference 1 is intended for fixing a chairlift or a gondola not visible in the figures on a cable 2.
  • This fixing device 1 is of the clamp type.
  • This clamp is generally identified by the reference 3 and comprises a first part 4 which has two end branches 5 and 6 spaced apart and a second part 7 which comprises an end branch 8 which extends between the branches 5 and 6 of the first part 4.
  • the branches 5, 6 and 8 have a U-shaped section groove open downwards in which the cable 2 extends so that these branches are supported on the cable 2 .
  • Part 7 of the clamp 3 is integral with an axis 9 which extends perpendicular to the cable 2 and horizontally on which the part 4 is mounted, and which carries the upper end of the suspension arm 10 of the cabin or chairlift .
  • a nut 11 At the end of the axis 9 is mounted a nut 11 which makes it possible to move the parts 4: and 7 of the clamp 3 one relative to the other perpendicular to the cable 2 so as to pinch the cable in the grooves branches 5, 6 and 8 in order to fix the device 1 on the cable 2.
  • the upper surface of the arms 5, 6 and 8 can constitute a rolling surface 12 parallel to the cable 2 on which rollers, for example the roller 13 which is supported on the cable 2, are driven to roll.
  • This rolling surface 12 is, in section perpendicular to the cable 2, rounded to substantially match the shape of the groove 13a of circular section of the roller 13.
  • the branches 5 and 6 of the clamp 3 respectively have an extension 14 and an extension 15.
  • extensions 14 and 15 extend in opposite directions along the cable 2 and have respectively two branches 16 and 17 and two branches 18 and 19 which extend laterally to the cable and on either side as well as a central part 20 and a central part 21 which respectively connect the branches 16 and 17 and the branches 18 and 19 and which extend above the cable.
  • the extensions 14 and 15 respectively provide a rolling surface or ramp 22 and a rolling surface or ramp 23 which extend the rolling surface 12 of the clamp 3 and which are inclined relative to the direction of the cable 2 over part of their length adjacent to the arms 5 and 6 so that their central parts 20 and 21 stop just above the cable 2 and their arms 16, 17 and 18, 19 extend further laterally to the cable 2.
  • the shape, in section perpendicular to the cable 2, of the rolling surfaces 22 and 23 formed by the extensions 14 and 15 is rounded, so as to extend the rolling surface 12 and to substantially match the groove 13a of the roller 13.
  • the roller 13 crosses the clamp 3 in the following manner.
  • roller 13 can cross the branches 5, 6 and 8 of the clamp 3 without causing impacts on the clamp 3 or on the cable 2 thanks to the extensions 14 and 15.
  • the present invention is not limited to the example described above. Indeed, the extensions 14 and 15 could be provided on a clamp locked by a spring and unlocked automatically using a lever.
  • the branches 16 and 18 of the extensions 14 and 15 could be eliminated in particular to allow the bending of the cable 2 in the direction which moves it away from the branches 17 and 19.
  • the rolling surfaces or ramps of the extensions 14 and 15 would be formed only by the branches 17 and 19 and the central parts 20 and 21.
  • extensions 14 and 15 which have been provided in the example in one piece with the branches 5 and 6 of the clamp 2 could be manufactured separately and assembled on the branches 5 and 6 by means of pins. articulation extending perpendicular to the cable 2 to be vertically movable.
