Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
254 words
In a wheel for a bicycle and like two-wheel vehicle including a shaft having an axis, a hub mounted on the shaft for rotation about said axis, a rim, said hub including a hub sleeve coaxial with said shaft, an input member rotatably mounted on said shaft, a portion of said input member extending outside said hub sleeve, motion-transmitting means for transmitting torque between said input member and said hub sleeve, said motion transmitting means being enclosed in said hub, and a plurality of elongated spokes having each a longitudinal end portion connected to said rim, and attaching means attaching the other end portion of each spoke to said hub sleeve, the improvement in said attaching means which comprises: a. a spoke attachment sleeve connected to said other end portion of each spoke, 1. said hub sleeve having an outer face and said spoke attachment sleeve having an inner face enveloping said outer face; b. a plurality of axially elongated ribs on each of said faces, the ribs on each face defining a plurality of grooves therebetween and being received in grooves between ribs on the other face; c. an axially terminal portion of one of said sleeves axially projecting beyond the other sleeve, 1. the projecting portion of said one sleeve being threaded; and d. a securing ring threadedly engaging said threaded portion and axially abutting against said other sleeve, 1. said spoke attachment sleeve being the sole element of said wheel capable of transmitting torque between said hub sleeve and said spokes.
Claim 2
Dependent Claim
254 words

Claim 3
Dependent Claim
36 words
In a wheel as set forth in claim 1, said ribs and grooves extending in an axial direction over at least a major part of the length of said hub sleeve and said spoke attachment sleeve.
Claim 4
Dependent Claim
17 words
In a wheel as set forth in claim 1, said motion-transmitting means comprising a multispeed gear system.
Claim 5
Dependent Claim
17 words
In a wheel as set forth in claim 3, said motion-transmitting means further comprising a back-pedalling brake.
Claim 6
Dependent Claim
17 words
In a wheel as set forth in claim 1, said one sleeve being said spoke attachment sleeve.
Claim 7
Dependent Claim
13 words
In a wheel as set forth in claim 5, the spokes being wire-members.
Claim 8
Dependent Claim
56 words
In a wheel as set forth in claim 5, the other axially terminal portion of said spoke attachment sleeve projecting beyond said hub sleeve in a direction opposite to the direction in which said one axially terminal portion projects, another securing ring threadedly engaging said other axially terminal portion and axially abutting against said hub sleeve.
Claim 9
Dependent Claim
37 words
In a wheel as set forth in claim 7, said axially terminal portions of said spoke attachment sleeve being internally threaded, and said hub sleeve having two radial end faces respectively abuttingly engaged by said securing rings.
Claim 10
Dependent Claim
22 words
In a wheel as set forth in claim 8, the spokes being fixed to said spoke attachment sleeve by welding or brazing.
Claim 11
Dependent Claim
