Bicycle rim reinforced with a continuously extending resin material
First Claim
1. A bicycle rim comprising:
- an annular metallic rim member including an annular tire attachment portion adapted to have a tire mounted thereon, a first annular side wall portion, a second annular side wall portion and an inner annular wall portion connecting the first and second annular side wall portions being formed of an extruded metallic material, with a plurality of spoke attachment openings formed in the inner annular wall portion, the first and second annular side wall portions having first and second annular braking surfaces that face in opposite directions and an external undercut surface extending between the first and second annular braking surfaces, respectively, the external undercut surface having annular transition sections offsetting the external undercut surface from the first and second annular braking surfaces; and
a reinforcing resin material having a rim facing surface attached to the annular metallic rim member such that the reinforcing resin material continuously extends from the first transition section across the inner annular wall portion to the second transition section to overlie exterior surface areas of the first and second annular side wall portions and exterior surface areas of the inner annular wall portion around the spoke attachment openings without overlying the first and second annular braking surfaces,the reinforcing resin material continuously overlying the annular transition sections of the external undercut surface about an entire circumferential area of the annular metallic rim member, and the rim facing surface of the reinforcing resin material being entirely directly attached to the extruded metallic material of the annular metallic rim member.

Abstract
A bicycle rim is provided with an annular metallic rim member and at least one reinforcing resin material. The annular metallic rim member includes an annular tire attachment portion adapted to have a tire mounted thereon, a first annular side wall portion, a second annular side wall portion and an inner annular wall portion connecting the first and second annular side wall portions with a plurality of spoke attachment openings formed in the inner annular wall portion. The at least one reinforcing resin material is attached to the annular metallic rim member such that the reinforcing resin material continuously extends from the first annular side wall portion across the inner annular wall portion to the second annular side wall portions to overlie exterior surface areas of the first and second annular side wall portions and exterior surface areas of the inner annular wall portion around the spoke attachment openings.

-
an annular metallic rim member including an annular tire attachment portion adapted to have a tire mounted thereon, a first annular side wall portion, a second annular side wall portion and an inner annular wall portion connecting the first and second annular side wall portions being formed of an extruded metallic material, with a plurality of spoke attachment openings formed in the inner annular wall portion, the annular metallic rim member having first and second annular braking surfaces that face in opposite directions and first and second transition sections formed in the first and second annular side wall portions radially inward of the first and second annular braking surfaces, the first and second annular side wall portions and the inner annular wall portion having wall thicknesses that are thinner in areas located radially inward of the first and second transition sections than wall thicknesses of the first and second annular side wall portions located radially outward of the first and second transition sections; and a reinforcing resin material having a rim facing surface attached to the annular metallic rim member such that the reinforcing resin material continuously extends from the first transition section across the inner annular wall portion to the second transition section to overlie exterior surface areas of the first and second annular side wall portions and exterior surface areas of the inner annular wall portion around the spoke attachment openings without overlying the first and second annular braking surfaces, the reinforcing resin material continuously overlying an entire circumferential area of the annular metallic rim member, and the rim facing surface of the reinforcing resin material being entirely directly attached to the extruded metallic material of the annular metallic rim member. - View Dependent Claims (11, 12, 13, 14, 15, 16)
