Definitions

  • This invention relates to a device for coupling a ski-bob to a ski lift and comprises a hook including a mobile element ensuring the closure of the hook, a spring biased lock for locking the mobile element in closed position and a control member operating, when actuated, on the lock to maintain the lock in a closed position against the action of the biasing spring.
  • This invention relates to a device for coupling a skibob to a ski lift.
  • a ski-bob is a device adapted for sliding on snow covered slopes and comprises generally two lined up skis of relatively short dimension.
  • the back ski is fixed to the structure of the ski-bob but the front ski is mounted on a steering axle permitting to control the ski-bob.
  • slope lifts of the ski lift types, for ski-bob adepts presents a security problem which has not been satisfactorily resolved so far.
  • An object of the present invention is to solve the abovementioned problem and to permit the always increasing number of adepts of this new sport to use ski lifts which were reserved until now to skiers alone.
  • the present invention guarantees that the skibob will be uncoupled every time that the circumstances require it.
  • the coupling device in accordance with the invention is characterized by the fact that it comprises, mounted on the ski-bob, a hook including a mobile element ensuring the closure of the hook, a spring biased lock for locking said mobile element in closed position, and a control member operating, when actuated, on said lock to maintain said lock in closed position, against the action of its biasing spring, whereby a ski-bob adept may, at the departing station of the ski lift, introduce in the hook a ring of the towing cable, close the hook, and by acting in a 3,620,168 Patented Nov. 16, 1971 continuous fashion on said control member, maintain said hook closed during the ascent, and by releasing the control member cause the automatic opening of the hook and the releasing of the ring to uncouple the ski-bob from the ski lift.
  • FIG. 1 is a front view of the coupling device in accordance with the invention.
  • FIG. 2 is a partial side view in the direction of arrow II of FIG. 1;
  • FIG. 3 is a section view taken along III-III of FIG. 2;
  • FIG. 4 is a View similar to FIG. 3 taken along IVIV of FIG. 2, illustrating the operation of the device.
  • the device illustrated in FIG. 1 comprises a portion mounted on an angle 10 riveted on an axle of the steering skate of a ski-bob, a control handle 11 secured to the handle bar of the ski-bob, and a control cable 12.
  • the portion of the device supported by the angle 10 comprises (FIGS. 2 and 3) a hook having a finger 13 pivoted at 14 on the horizontal portion 15 of angle 10, this hook being intended to receive a ring A of a towing cable B of a ski lift, and further comprises a lock 16 including a lever 17 pivoted in a bearing 18 and a biasing spring 19.
  • the bearing 18 is part of a member 20, welded on the portion 15 of angle 10, which has two legs 21 to which are respectively attached the spring 19 and the end of the sheath of cable 12, which end is provided with an adjusting screw 22.
  • the locking portion of lever 17 comprises a catch 23.
  • lever 17 takes the position shown in FIG. 4, position in which catch 23 is retracted and does not prevent the finger 13 of the hook to swing back (FIG. 2) when a traction is exerted on it by ring A.
  • lever 17 pivots against the action of spring 19 and catch 23 locates itself in the path of hook 13 which is thereby locked in position (FIGS. 1, 3 and 4).
  • Screw 22 permits to adjust the locking position of lever 17.
  • the coupling device illustrated and disclosed operates as follows: At the departing station of the ski lift, the skibob adept gets hold of a ring A of the towing cable, engages it in the hook 13, and locks the hook by pulling the handle 11 against the handle bar. The ski-bob is thereby coupled to the towing cable by which it is pulled. When the ski-bob adept arrives at the top of the hill, he releases the handle 11 which causes the hook '13 to pen under the pull of the towing cable. The ring A is released from the book 13 and the ski-bob is uncoupled from the ski lift.
  • the portion of the device mounted on the axle of the steering skate could be fixed on the handle bar on the frame of the ski-bob if the stability of the equilibrium of the skibob adept could be improved that way.
  • a second spring may be provided, working for example in compression if the first spring 19 works in tension to increase the security of operation of the device. Indeed, a breaking of the spring 19 could occur during the ascent of the ski-bob adept which would impair the opening of the hook and consequently the release of the ski-bob if a second safety spring is not provided.
  • the catch 23 may be designed in such a way that hook 13 is automatically released from lock 16 under the action of a pull on ring A if lever 17 is not subjected to the action of the biasing spring or springs, for example in the case of a breaking of the spring or springs. That way, a triple security of operation of the device may be realized.
  • a device for coupling a ski-bob to the towing cable of a ski lift comprising:
  • a lock mounted on said support and adapted, when operated, to maintain said mobile element into a position ensuring the closure of the hook, said lock comprising a lever having a catch which is adapted to be positioned in the path of the mobile element of said hook when the lock is operated;
  • ski-bob includes a steering axle and wherein said support is mounted on said steering axle.
