Abstract
A wheel for light vehicles and a disc member used therein. The wheel comprising a hub, a rim and a pair of disc members detachably coupled with the hub and the rim, wherein the wheel has the advantage of a spoke wheel that it is lightweight and has sufficient strength as well as the advantage of a disc wheel that it has less air resistance when it rotates, and further the wheel can be easily repaired when it is damaged.
Claims8
A wheel for light vehicles, comprising:
- a hub including a rotating shaft;
- a rim surrounding the hub at a predetermined distance;
- a pair of disc members with each disc member composed of at least one smooth surfaced, sheet member stretched between said hub and said rim for coupling the former with the latter;
- and
- each of said disc members has an opening defined at the center thereof to fit said hub, an inner circumferential edge detachably coupled with said hub and an outer circumferential edge detachably fixed to said rim by screw threading means and said disc member is stretched by a tensile force applied by said screw threading means and corresponding to the extent of threading of said screw threading means.
