Abstract
A bicycle wheel includes a wheel rim and a plurality of spokes. The wheel rim includes spaced left and right tire retaining walls that are interconnected by a base wall. Each of the tire retaining walls is formed with a set of spoke mounting holes, each of which extends through lateral outer and inner surfaces of the tire retaining wall. Each spoke has an inner end portion mounted on a hub, and an outer end portion which includes an enlarged head abutting against the lateral outer surface of the respective tire retaining wall, an extending section received in a respective spoke mounting hole, and a bending section disposed adjacent to the lateral inner surface of the respective tire retaining wall. The bending section is bent from the extending section, and extends toward the inner end portion of the spoke.
Claims6
A bicycle wheel adapted to be installed on a wheel axle, said bicycle wheel comprising:
- a hub adapted to be mounted rotatably on the axle, said hub having left and right end portions which are opposite to each other along an axis of the axle, each of said left and right end portions being formed with a set of spoke fastening holes which are arranged around the axis of the axle;
- a wheel rim disposed around said hub, said wheel rim including spaced-apart left and right annular tire retaining walls, each of which has a radial inner section proximate to said hub, a radial outer section distal to said hub, and an intermediate section between said radial inner and radial outer sections, said radial outer sections of said tire retaining walls being adapted for retaining a bicycle tire therebetween, said radial inner section of each of said tire retaining walls having a lateral inner surface confronting said radial inner section of another one of said tire retaining walls, and a lateral outer surface opposite to said lateral inner surface, said radial inner section of each of said tire retaining walls being formed with a set of spoke mounting holes, each of which extends through said lateral outer surface and said lateral inner surface of said radial inner section of a respective one of said tire retaining walls, said wheel rim further including an annular base wall interconnecting said intermediate sections of said tire retaining walls;
- and
- a plurality of spokes, each of which has an inner end portion mounted on a respective one of said spoke fastening holes in one of said left and right end portions of said hub, and an outer end portion mounted on a respective one of said spoke mounting holes in said radial inner section of one of said tire retaining walls, said outer end portion of each of said spokes including an enlarged head abutting against said lateral outer surface of said radial inner section of a corresponding one of said tire retaining walls, an extending section connected to said enlarged head and received in the respective one of said spoke mounting holes, and a bending section which is connected to said extending section and which is disposed adjacent to said lateral inner surface of said radial inner section of the corresponding one of said tire retaining walls, said bending section being bent from said extending section and extending from said extending section toward said inner end portion of said spoke.
