Abstract
A spoke attachment assembly configured to couple a rim to the spokes of a spoked bicycle wheel. The spoke attachment assembly comprises a nipple having an enlarged head and a stem provided with a coupling portion for coupling with a spoke, at least one shaped washer associated with the nipple and configured to abut on one side with the enlarged head of the nipple and, on the opposite side, with the rim and holding means configured to hold said at least one shaped washer associated with the nipple. The invention also relates to a spoked bicycle wheel and to a process for manufacturing such a wheel.
Claims15
A spoke attachment assembly, configured to be coupled to a rim of a spoked bicycle wheel, comprising:
- a nipple having an enlarged head and a stem provided with a coupling portion for coupling to a spoke;
- at least one shaped washer associated with the nipple and configured to abut on one side with the enlarged head of the nipple and, on the opposite side, with the rim;
- and,
- holding means configured to hold said at least one shaped washer associated with the nipple.
A spoked bicycle wheel, comprising:
- a rim comprising a tyre coupling channel and at least one spoke attachment chamber, the at least one spoke attachment chamber being provided with at least one opening and with a spoke attachment surface comprising a plurality of spoke attachment seats, said at least one opening comprising a number of openings smaller than a number of spoke attachment seats;
- a plurality of nipples each having an enlarged head arranged in said at least one spoke attachment chamber and a stem inserted in a respective spoke attachment seat and provided with a coupling portion for coupling to a respective spoke;
- a plurality of spokes each having an end portion coupled to the coupling portion of the stem of a respective nipple;
- and
- for each respective nipple, at least one shaped washer applied onto the stem of the nipple and in abutment on one side with the enlarged head of the nipple and, on the opposite side, with the spoke attachment surface.
A process for manufacturing a spoked bicycle wheel, the process comprising the steps of:
- a) providing a rim element having a tyre coupling channel and at least one spoke attachment chamber, the at least one spoke attachment chamber being provided with at least one opening and with a spoke attachment surface comprising a plurality of spoke attachment seats;
- b) inserting a spoke attachment assembly into the at least one spoke attachment chamber through said at least one opening, said spoke attachment assembly comprising:
- a nipple having an enlarged head and a stem provided with a coupling portion for coupling to a respective spoke;
- at least one shaped washer;
- holding means configured to hold said at least one shaped washer associated with the nipple;
- c) moving said spoke attachment assembly along said spoke attachment surface and up to one of said spoke attachment seats;
- d) inserting the stem of the nipple of said spoke attachment assembly in said spoke attachment seat;
- e) constraining said spoke attachment assembly to said spoke attachment seat;
- f) repeating steps b) to e) and coupling a respective spoke attachment assembly to each other spoke attachment seat.
