no. 2 example

[0066] see now Figure 9 with 10 , which shows a central hub 120 consistent with a second embodiment of the invention. The central hub 120 is substantially the same as the central hub 20 of the first embodiment except for parts to be described below. Therefore, the central hub 120 will not be described and shown in detail here. The central hub 120 is designed to use spoke nipples 28 to attach the spokes 22 and rim 24 thereto.

[0067] Basically, the central hub 120 has a tubular body portion 130, a left tubular mounting portion 132a and a right tubular mounting portion 132b. The left tubular mounting portion 132a is formed by a plurality of spoke attachment protrusions 138a and a tapered portion 139a. The tapered portion 139a securely connects the left tubular mounting portion 132a to the tubular body portion 130 . The spoke attachment protrusions 138a are provided with a plurality of spoke attachment holes 134a formed therein. The spoke attachment holes 134a are differe...

[0072] see now Figure 11 with 12 , which shows a central hub 220 consistent with a third embodiment of the invention. The central hub 220 is substantially the same as the central hub 20 of the first embodiment except for parts to be described below. Therefore, no detailed description and illustration of the central hub 220 will be made here. The central hub 220 is designed so that the spokes 22 and rim 24 can be connected thereto using spoke nipples 28 .

[0073] Basically, the central hub 220 has a tubular body portion 230, a left tubular mounting portion 232a and a right tubular mounting portion 232b. The left tubular mounting portion 232a is formed by a plurality of spoke attachment protrusions 238a and a tapered portion 239a. The left tubular mounting portion 232a is substantially the same as the left tubular mounting portion 32a of the first embodiment. The tapered portion 239a securely connects the left tubular mounting portion 232a to the tubular body portion 230 ...

Abstract

A bicycle wheel basically has a hub, a plurality of spoke nipples, a plurality of spokes extending outwardly from the hub and an annular rim coupled to the outer ends of the spokes for supporting a tire. The annular rim has a pair of spoke attachment portions with a plurality of openings for retaining outer ends of spokes therein. The outer ends of the spokes have bent sections located within the spoke holes of the rim and enlarged head members arranged to engage the spoke attachment portions. The hub has a pair of tubular mounting portions. Each tubular mounting portion has a plurality of mounting projections and a plurality of spoke attachment openings.

Description

technical field [0001] The present invention relates generally to spoke nipples for bicycle wheels. More particularly, the present invention relates to bicycle wheels that use spoke nipples to connect the spokes to the hub. Background technique [0002] Cycling is becoming an increasingly popular form of recreation and transportation. In addition, cycling has also become a very common competitive sport for both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving various parts of the bicycle. One particular bicycle part that has undergone numerous redesigns over the years is the bicycle wheel. There is ongoing redesign of bicycle wheels in order to make them lighter in weight, better in aerodynamic shape and easier to manufacture and assemble. [0003] There are many different styles of bicycle wheels currently available on the market. The most basic bicycle wheel has a hub se...
