Abstract
A device for pulling a skater including a longitudinal frame, handle bars provided at the upper end potion of the frame and a ground engaging drive wheel rotatably coupled to a lower end portion of the frame. A prime mover is mounted on the frame so as to drive the drive wheel, and a unit for controlling a rotational speed of the drive wheel is coupled thereto. An arm having at least one ground engaging jockey wheel is rotatably coupled to one end thereof and in movably connected at its opposite end to the frame in such a manner that the jockey wheel is disposed substantially rearwardly of the drive wheel when the device is in use.
Claims24
A device for pulling a skater comprising:
- a longitudinal extending frame having an upper end portion and a lower end portion, and defining a steering axis,
- handle bars provided at the upper end portion of said frame,
- a ground engaging drive wheel rotatably coupled to the handle bars of said frame and tiltable about said steering axis of said frame by operation of the handle bars,
- a prime mover mounted on said frame so as to drive said drive wheel,
- means for controlling a rotational speed of said drive wheel, and
- an arm having at least one ground engaging jockey wheel rotatably coupled to one end of said arm, and said arm being movably connected at another end of said arm to said frame in such a manner that said jockey wheel is disposed substantially rearwardly of the drive wheel when the device is in use and said arm is rotatable about said axis of said frame.
A device for pulling a skater comprising:
- a frame having a steering axis;
- at least one steering member provided at an upper end portion of said frame;
- a drive wheel tiltable about the steering axis of the frame such that a plane of the drive wheel tilts relative to the ground;
- a first device driving said drive wheel, said first device mounted to said frame to rotate about said steering axis to permit tilting of the drive wheel relative to the ground;
- a second device controlling a rotational speed of said drive wheel;
- an arm connected to a rearwardly disposed jockey wheel;
- and
- said arm being rotatable about the steering axis of the frame.
