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.
Claims14
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, the at least one shaped washer comprising a substantially flat radially inner surface and a radially outer surface, the radially outer surface configured to abut the enlarged head of the nipple and the substantially flat radially inner surface configured to abut the rim;
- and,
- holding means configured to hold said at least one shaped washer associated with the nipple,
- wherein said spoke attachment assembly comprises a portion made of a magnetically attractable material and wherein said holding means are of a magnetic type.
The 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, the at least one shaped washer comprising a substantially flat radially inner surface and a radially outer surface, the radially outer surface configured to abut the enlarged head of the nipple and the substantially flat radially inner surface configured to abut the rim;
- and,
- holding means configured to hold said at least one shaped washer associated with the nipple,
- the spoke attachment assembly comprising an insert made of a magnetically attractable material, said insert defining said holding means and being removably associated with the nipple.
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, the at least one shaped washer comprising a substantially flat radially inner surface and a radially outer surface, the radially outer surface configured to abut the enlarged head of the nipple and the substantially flat radially inner surface configured to abut the rim;
- and,
- holding means configured to hold said at least one shaped washer associated with the nipple;
- wherein said at least one shaped washer has a predetermined inner diameter and said holding means comprise a holding washer mounted in a groove made on an outer surface of the stem of the nipple on the opposite side to said at least one shaped washer with respect to the enlarged head of the nipple, wherein said holding washer has an outer dimension greater than the inner diameter of said at least one shaped washer, and wherein said holding washer is made of a water-soluble material to allow its removal after having positioned the stem of the nipple in a spoke attachment seat.
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, the at least one shaped washer comprising a substantially flat radially inner surface and a radially outer surface, the radially outer surface configured to abut the enlarged head of the nipple and the substantially flat radially inner surface configured to abut the rim;
- and,
- holding means configured to hold said at least one shaped washer associated with the nipple;
- wherein said holding means comprise an adhesive substance interposed between said at least one shaped washer and the head and/or the stem of the nipple.
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.
