Abstract
A method is intended for manufacturing a bicycle spoked wheel. By inserting the nipples or barrels for the attachment of the spokes in the spoke attachment seats from the inside of the spoke attachment chamber instead of from the outside, after having inserted them in the chamber from a suitably sized opening, the rim of the bicycle wheel can be manufactured even without additional openings, still using conventional nipples or barrels.
Claims21
A bicycle rim having a tire coupling channel and at least one spoke attachment chamber comprising:
- i) a plurality of spoke attachment seats, each spoke attachment seat being intended to receive a spoke attachment element with a shank thereof partially protruding from the at least one spoke attachment chamber and a head thereof widened with respect to the shank held inside the at least one spoke attachment chamber;
- and
- ii) at least one opening suitable for the passage of the spoke attachment elements, wherein a shortest circumferential distance between a selected one of the spoke attachment seats and one of the at least one opening that is nearest thereto includes a second one of the spoke attachment seats.
A bicycle accessory comprising:
- a) a rim having a tire coupling channel and at least one spoke attachment chamber comprising:
- i) a plurality of spoke attachment seats, each spoke attachment seat being intended to receive a spoke attachment element with a shank thereof partially protruding from the at least one spoke attachment chamber and a head thereof widened with respect to the shank held inside the at least one spoke attachment chamber;
- and
- ii) at least one opening suitable for the passage of the spoke attachment elements, wherein the at least one opening are less in number than the spoke attachment seats and at least one of the spoke attachment seats is not adjacent to any of the at least one opening, wherein a shortest circumferential distance between a selected one of the spoke attachment seats and one of the at least one opening that is nearest thereto includes a second one of the spoke attachment seats;
- b) a plurality of the spoke attachment elements;
- and
- c) a means for holding the spoke attachment elements with the respective shank aligned with the respective spoke attachment seat.

A bicycle wheel assembly comprising:
- a hub;
- a plurality of spokes;
- a rim having joined first and second ends, an upper bridge, a lower bridge, and opposite side walls, forming a spoke attachment chamber therebetween;
- a plurality of magnetically interactive spoke attachment elements that attach the rim to the spokes;
- and
- a magnetic element;
- wherein a plurality of spoke attachment apertures are formed in the lower bridge, each receiving a respective one of the spoke attachment elements with a shank thereof partially protruding from the spoke attachment chamber and a head thereof held inside the at least one spoke attachment chamber;
- at least one opening is formed in the upper bridge, the at least one opening dimensioned for the passage of the spoke attachment elements into the spoke attachment chamber;
- and
- the magnetic element is suitable to attract the spoke attachment elements, to draw the spoke attachments elements from the at least one opening along the spoke attachment chamber to respective spoke attachment apertures while remaining outside of the spoke attachment chamber.
