Abstract
A hollow wheel is rotatively mounted on a vehicle about an axis of rotation defining an acute angle with the vertical. This wheel comprises a first convex side wall having an outer face defining a circular and axially tapering tread centered on the axis of rotation, and a second side wall spaced apart from and connected to the first side wall to form the hollow wheel. A tube, centered on the axis of rotation, interconnects the first and second side walls to receive an axle. The tread is generally conical and presents a convex cross section. Preferably, the interconnected first and second side walls form a water-tight hollow body presenting buoyancy. The hollow wheel can be used on ground, water and snow.
Claims14
A wheel to be rotatively mounted on a movable object about an axis of rotation defining an acute angle with the vertical, comprising:
- a plane of symmetry;
- first and second opposite side faces symmetrical with respect to said plane of symmetry, said first and second side faces being both convex and defining respective circular and axially tapering treads centered on said axis of rotation and symmetrical with respect to said plane of symmetry;
- and
- means for rotatively mounting said wheel on the movable object about said axis of rotation where one of said treads is capable of engaging a wheel-supporting surface.
