Definitions

  • the invention relates to a device for attaching a tow bar to the circumferential rope of a ski lift with a bracket for the tow bar rotatable about the rope axis.
  • the invention is therefore based on the object to avoid these deficiencies and to improve a device for attaching a towing bracket to the circumferential rope of a ski lift so that the towing bar can be easily brought into the most advantageous position for the ski lift user without the course of the rope need to change.
  • the invention solves this problem in that the holder has an arm protruding from the rope, at the end of the rope facing away from the tow bar rotatably mounted about an axis running at least approximately parallel to the rope and can be rotated by means of a handle.
  • the tow bar Since the tow bar is not rigidly connected to the bracket, but is rotatable about an axis that runs at least approximately parallel to the rope, the tow bar can be adjusted in height parallel to itself without having to shift the rope in height, because yes over the Swivel position of the protruding arm of the bracket, the height of the towbar is determined.
  • the tow bar can therefore be adjusted by the ski lift user via the handle to the most favorable towing position for the ski lift user, whereby only the towing forces running in the conveying direction can be transferred to the ski lift user via the tow bar, but not transverse forces.
  • the drag bar is attached to one end of a shaft which passes through a bearing bush on the arm of the holder and carries the handle at its other end.
  • this shaft runs approximately parallel to the angled forearm of a ski-lift user at the drag height of the towbar, so that the turning adjustment of the towbar via the handle is carried out essentially by turning the forearm about its longitudinal axis.
  • the handle can be arranged with an angular offset with respect to the drag bar with respect to the axis of rotation of the drag bar. This ensures an optimal application of force to adjust the tow bar. Due to the anatomical conditions, there is an advantageous angle between the handle and the tow bar between 60 ° and 90 °.
  • the drag bar can be rotated from a rest position pivoted against the arm of the bracket against the force of a return spring into a position of use protruding from the arm, the drag bar returns after its use to the rest position pivoted against the arm of the bracket, in which the bracket with the Due to the weight, the tow bar hangs down from the rope because the bracket is freely rotatable around the rope axis.
  • the length of the device remains limited to the length of the arm of the bracket when the towing bracket is pivoted in.
  • the device shown consists essentially of a bracket 2 fastened to a peripheral rope 1 of a ski lift, which is rotatably mounted about the rope axis and carries a drag bar 3.
  • the drag bar is not connected in a rotationally fixed manner to the holder 2, but is rotatably mounted at the end of an arm 4 of the holder 2 protruding from the cable 1 about an axis running at least approximately parallel to the cable 1.
  • the arrangement is such that the arm 4 carries at its end a bearing bush 5, which is penetrated by a shaft 6, on the rear end of the tow bar 3 with respect to the towing direction indicated by the arrow 7 and a handle 8 at the front end thereof are attached to twist the tow bar 3.
  • a bearing bush 5 which is penetrated by a shaft 6, on the rear end of the tow bar 3 with respect to the towing direction indicated by the arrow 7 and a handle 8 at the front end thereof are attached to twist the tow bar 3.
  • the handle 8 is offset relative to the drag bar 3 with respect to the axis of rotation of the drag bar by an angle a, which in the exemplary embodiment is approximately 75 ° and can advantageously be between 60 ° and 90 °, to the natural hand position to take into account when rotating the bracket 3 in the use position.
  • the drag bar 3 is held by a spring not recognizable in the drawing in a position swung in against the bracket 2, so that the bracket with the bracket 3 hangs down from the rope 1 due to weight.
  • the arm 4 of the bracket 2 is pivoted up into a roughly horizontal rotational position by a suitable guide device, the drag bar 3 being rotated at the same time so that it is directed downward and the handle 8 is the ski lift user counter-strikes, as indicated by dash-dotted lines in FIG. 2.
  • the ski lift user grasps the handle 8 and is twisted.
  • the ski lift user grasps the handle 8 and rotates the handle 3 via the handle 8 into the use position in which the drag bar projects approximately horizontally from the arm 4 of the holder 2 (FIGS. 1 and 2). Since the shaft 6 runs approximately parallel to the forearm of the ski lift user when the handle 8 is rotated, an advantageous force application is ensured by the ski lift user, which makes the handling of the device easy. Via the handle 8, the tow bar 3 can also be adjusted in height without having to move the rope 1, because the tow bar 3 is pivotally mounted relative to the arm 4 and the arm 4 relative to the rope 1.
