Definitions

  • a ski bob comprising a frame and a pair of axially aligned runners in which the front runner is steerable by handlebars pivotally mounted on the frame and one of the runners, usually the rear runner, is provided with a rotating mechanism so that it may be rotated about a longitudinal axis for transverse movement relative to the frame so that the runner is caused to edge" as the bob turns in snow.
  • the rotating mechanism is controlled by a twist grip on the handlebars.
  • the apparatus of the invention is characterized by the fact that at least one of the runners is articulated on the frame along a longitudinal axis and provided with actuating means permitting it to oscillate along the said axis in respect of said frame.
  • FIG. 1 is a side view of the apparatus.
  • FIG. 2 is a vertical section, on a larger scale, of the actuating device situated between the rear bar of the frame and the corresponding runner.
  • FIGS. 3 and 4 are elevated diagrammatic views from the rear illustrating the operation of the apparatus.
  • FIG. 5 is a side perspective view of the actuating device.
  • the ski bob shown in FIG. 1 comprises a frame having a general U-shaped profile and supported by two runners 2 and 3.
  • the front runner 2 is articulated on a transverse axis 4 provided on the lower extremity of a steering-column 5, the top of which is equipped with a handle-bar 6.
  • This column 5 is pivotally supported by two angle-irons 7 solid with the front bar of the frame 1.
  • the frame is equipped with a saddle 8 attached to a telescopic shock absorber 9, the base of which is resting on a bracket 10.
  • an actuating device as shown in FIG. 2, which device is controlled on the handle-bar 6 by means of a rotating grip of the type used on motor bikes and similar apparatus.
  • the actuating device comprises a horizontal casing 12 having a cylindrical profile and facing crosswise in respect of the runner 3, the upper wall of the casing 12 being solid with a vertical rod 13 which fits into the open base of the rear bar of the frame 1. This rod may be secured angularly in any appropriate manner.
  • the casing 12 encloses a shaft 14 supported by two bearings 15 and 16; this shaft is enclosed within a threaded cap 17 screwed into the threaded opening of the casing 12.
  • the shaft 14 extends beyond the bearing 15 and the 6 end surface of the casing 12 to carry a drum 18 which is solid with said shaft.
  • a drum 18 which is solid with said shaft.
  • the extremities of two cables 20 are secured to this drum and enclosed in sheathes 21, which are attached to the above-mentioned bracket 10 by means of ordinary couplings 22.
  • the cables 20 end at an upper drum 23 (FIG. 1) angularly solid with the rotating grip 11, so that the turning of said grip causes the rotation of the drum 18 and the shaft 14 in one direction or the other.
  • the turning of the grip 1 1 permits the horizontal swivelling of the runner 3 following the longitudinal axis 26, by means of the cables 20, the endless screw and the sector 25, in the manner illustrated in FIGS. 3 and 4.
  • the driver at the same time as he changes the direction of the handle-bar 6, may begin a controlled skidding to make a sharp turn, or on the other hand, he may, using the technique known in skiing as edging, firmly hold the apparatus onto a gentle curve. In either case, he does not have to brake using the usual foot grips or exert any pressure on the frame 1.
  • the articulation of the runner 3 around the pins 27 permits this runner to pivot so as to follow the irregularities of the trail.
  • the front extremity of the runner 3 is attached to the base of the front bar of the frame 1 by means of a flexible piece 30 of rubber or similar material, which does not interfere with the transversal or longitudinal movement of the runner in question.
  • the actuating device situated between the frame and the rear runner could be provided with a swivel-joint.
  • this device could be controlled by the steering-column 5, so that the runner oscillates automatically when the direction of the handle-bar is changed.
  • the front runner 2 may be directly connected to an actuating device which is either independent or synchronized with that of the rear runner 3.
  • the actuating device or devices may be driven by an electric or other type of motor operated by the driver.
  • a ski-bob or like apparatus for sliding on snow including a frame; at least one runner to support said frame; and connecting means to attach said runner to said frame; the improvement according to which said connecting means comprise:
  • said means to secure said gear sector to said runner comprising:
  • said runner having an upper side
  • said support including a sill rigidly secured onto the upper side of said runner, and a pair of lateral lugs solid with said sill, with said gear sector situated between said lugs;
  • said means to pivot said gear sector to said support comprising a pair of opposed pins rotatably carried by said lugs along said substantially transverse axis, each of said 5 pins having a threaded inner end screwed into said gear sector.
  • said means to rotate said endless screw comprising:
  • cable means attached to said drum and wound thereon, said cable means having two ends in opposed relation to each other with respect to said drum;
  • said means to selectively pull each end of said cable means including a rotatable grip mounted on said frame.
  • said frame including a steering column
  • said frame further including a handlebar secured to i said steering column to control same; and said means to selectively pull each end of said cable means comprising a rotatable grip mounted on said handlebar.
  • said frame including a steering column angularly
