Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A device for rotatably supporting a hub of a bicycle wheel, comprising: a shaft arranged through a cavity of the hub, a pair of rolling bearings interposed between an outer surface of the shaft and a surface of the cavity of the hub, each bearing comprising an inner ring and an outer ring respectively secured to the shaft and the hub, and means for locking said bearings in the assembled condition, wherein said means include at least one annular element having an outer conical surface interposed between the outer surface of shaft and the inner ring of one of said bearings, the inner ring of this bearing having an inner surface at least partially conical in contact with the conical surface of said conical annular element, means being provided for axially pushing the conical annular element between the shaft and the bearing towards an operative position in which it stably secures the inner ring of said bearing in rotation on said shaft, said means being further adapted to lock said conical annular element in said operative position.
Claim 2
Independent Claim
177 words
A device for rotatably supporting a hub of a bicycle wheel, comprising: a shaft arranged through a cavity of the hub, a pair of rolling bearings interposed between an outer surface of the shaft and a surface of the cavity of the hub, each bearing comprising an inner ring and an outer ring respectively secured to the shaft and the hub, and means for locking said bearings in the assembled condition, wherein said means include at least one annular element having an outer conical surface interposed between the outer surface of shaft and the inner ring of one of said bearings, the inner ring of this bearing having an inner surface at least partially conical in contact with the conical surface of said conical annular element, means being provided for axially pushing the conical annular element between the shaft and the bearing towards an operative position in which it stably secures the inner ring of said bearing in rotation on said shaft, said means being further adapted to lock said conical annular element in said operative position.
Claim 3
Dependent Claim
41 words
A device according to claim 1, wherein said means for axially pushing the conical annular element comprises an inwardly threaded ring nut screwed on a threaded end portion of the shaft and provided with means for locking thereof on the shaft.
Claim 4
Dependent Claim
40 words
A device according to claim 1, wherein said means for axially pushing the conical annular element comprises an annular clamp slidably mounted on a non-threaded end portion of the shaft and provided with means for locking thereof on the shaft.
Claim 5
Dependent Claim
38 words
A device according to claim 1, wherein a single conical annular element is used with one bearing, the other bearing being locked on a portion of the shaft having a conical surface and formed directly on the shaft.
Claim 6
Dependent Claim
61 words
A device according to claim 1, wherein the shaft has a regular cylindrical shape and in that there are provided two conical annular elements to be used with the two bearings, one of these conical elements being directly subjected to the force imparted by said pressing means, the other conical annular element abutting against a stop element connected to the shaft.
Claim 7
Dependent Claim
13 words
A device according to claim 1, wherein the shaft is of metal material.
Claim 8
Dependent Claim
13 words
A device according to claim 1, wherein the shaft is of composite material.
