Abstract

Abstract In this improved skilift pole distributor a lever is pivoted about a horizontal fixed fulcrum in a support overlying the path followed by the sockets and studs provided at the upper end of each pole for wedging the traction rope in the socket, the stud projecting radially from said socket, the lever is connected through links to a pair of vertical stop members disposed on either side of the fulcrum and adapted one to engage said socket and the other said stud, the other stop member comprises at its lower end a bevelled face adapted to engage the stud of the first waiting pole at the starting station of the skilift where the waiting poles are accumulated. The arrangement is such that any undue wedging of sockets by the first stop member is safely prevented to provide a reliable, trouble-free operation of the pole distributor.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 348 words
A skilift of the type comprising a plurality of successive poles each including at the upper end thereof, an anchoring body having a rigid stud laterally projecting on one side of the pole and a rigid socket laterally projecting on the other side of the pole and adapted to be anchored by wedging to a traction rope such that the anchoring body can advance along a path of travel, the stud on each body being spaced forwardly of the socket on the same body, and a pole distributor comprising a lever, a fixed horizontal fulcrum disposed above the path of travel of the sockets and studs, said lever being pivotably connected to said horizontal fulcrum, first and second stop members disposed vertically and attached to said lever on either side of said fulcrum in laterally spaced relation corresponding to the lateral spacing between the sockets and studs, the second stop member being spaced forwardly of the first stop member, return means acting on said lever to urge said lever to an inoperative position in which the lower end of the first stop member lies in the path of the sockets and prevents release of the first waiting pole while the second stop member is above the stud of said first pole, and control means for pivoting said lever to a distributing position in which, on the one hand, said second stop member moves into the path of said studs for preventing any advance thereof while displacing the stud of said first pole forwardly and, on the other hand, said first stop member rises to a position above the path of said sockets, said first stop member being so spaced in the direction of travel of the ski poles with respect to the second stop member such that when the second stop member engages the stud of the next pole, the first stop member is spaced ahead of the socket associated with said next pole, each anchoring body thereby being successively contacted at laterally spaced locations on its stud and socket by said second and first stop members respectively.
Claim 2
Dependent Claim 348 words
A skilift of the type comprising a plurality of successive poles each including at the upper end thereof, an anchoring body having a rigid stud laterally projecting on one side of the pole and a rigid socket laterally projecting on the other side of the pole and adapted to be anchored by wedging to a traction rope such that the anchoring body can advance along a path of travel, the stud on each body being spaced forwardly of the socket on the same body, and a pole distributor comprising a lever, a fixed horizontal fulcrum disposed above the path of travel of the sockets and studs, said lever being pivotably connected to said horizontal fulcrum, first and second stop members disposed vertically and attached to said lever on either side of said fulcrum in laterally spaced relation corresponding to the lateral spacing between the sockets and studs, the second stop member being spaced forwardly of the first stop member, return means acting on said lever to urge said lever to an inoperative position in which the lower end of the first stop member lies in the path of the sockets and prevents release of the first waiting pole while the second stop member is above the stud of said first pole, and control means for pivoting said lever to a distributing position in which, on the one hand, said second stop member moves into the path of said studs for preventing any advance thereof while displacing the stud of said first pole forwardly and, on the other hand, said first stop member rises to a position above the path of said sockets, said first stop member being so spaced in the direction of travel of the ski poles with respect to the second stop member such that when the second stop member engages the stud of the next pole, the first stop member is spaced ahead of the socket associated with said next pole, each anchoring body thereby being successively contacted at laterally spaced locations on its stud and socket by said second and first stop members respectively.
Claim 3
Dependent Claim 46 words
The device according to claim 1, wherein said second stop member has a lower end with a bevelled face inclined downwards and backwards in relation to the direction of movement of said studs to engage the stud of the first waiting pole and cause advance thereof.
Claim 4
Dependent Claim 15 words
The device according to claim 1 comprising links coupling said stop members to said lever.
