Problems solved by technology

[0006] Additionally, rim failure can also occur when the tire fails to protect the rim from impact due to a severe impact or, for example, under inflated air, causing the rim to bend or crack, loosening spokes and potentially dangerous failure of the entire wheel

Embodiment Construction

[0018] Preferred embodiments of the present invention will be described herein with reference to the accompanying drawings. It is to be understood that the drawings and descriptions described herein are for purposes of illustration and not limitation of the invention as defined by the appended claims and any and all equivalents thereof.

[0019] figure 1 and figure 2 A clipper rim 20 is shown wherein the beads 22 , 24 of a clipper tire 26 are held over the rim. The rim 20 generally includes a radially outer tire engaging portion 28, a radially inner spoke engaging portion 30, a first sidewall 32, and a second sidewall 34 spaced from the first sidewall. The first sidewall 32 and the second sidewall 34 extend between the tire engaging portion 28 and the spoke engaging portion 30 to generally form the shape of the rim 20 .

[0020] The tire engaging portion 28 includes a pair of circumferential bead engaging members 36 , 38 for engaging the beads 22 , 24 of the tire 26 . It ...

Abstract

The present invention relates to a bicycle rim having an integral impact-resistant structure. An FRP rim for a bicycle is provided, which includes a radial outer tire joint portion and a radial inner spoke joint portion. The first side wall and the second side wall are in a spaced configuration. The first sidewall and the second sidewall extend between the radial casing joint and the radial inner spoke joint, and one or more integral bumpers are positioned on the radial casing. On the outermost radial extension or peak of the joint.

Description

technical field [0001] The present invention relates to bicycle rims, and more particularly, to bicycle rims having an integral impact-resistant structure and methods of making the same. Background technique [0002] Bicycle rims are made from a variety of materials. For example, wheel rims have historically been made of wood, metals such as steel and aluminum alloys, and more recently composite materials such as carbon fiber reinforced materials and the like. Often, composite rim materials are generally referred to as fiber-reinforced plastics or fiber-reinforced polymers (FRP). [0003] Most bicycle rims fall into two groups that classify tire types according to what they are designed to do. One common type of rim is called a clincher rim, which is used with either clincher-style tires or tubeless tires. Clincher and tubeless tires typically have a wire or aramid (Kevlar) fiber bead that interlocks with sidewall flanges in the rim. A separate airtight inner tube, parti...
