Patent number: 7192098Abstract: A bicycle rim includes a tire attachment portion a spoke attachment portion and a plurality of reinforcement members fixedly coupled to the spoke attachment portion at attachment openings to effectively increase the thickness of the spoke attachment portion at the attachment openings. Each reinforcement member includes a rim facing surface that contacts the rim, an exterior facing surface facing and a through opening extending between the rim facing surface and the exterior facing surface that is aligned with one of the attachment openings. Each of the reinforcement members is preferably welded to the spoke attachment portion. Each of the reinforcement members preferably has a maximum overlapping dimension overlapping the spoke attachment portion as measured from an outer peripheral edge to a respective one of the attachment openings with the maximum overlapping dimension being at least half as large as a maximum transverse dimension of the attachment openings.Type: GrantFiled: May 7, 2003Date of Patent: March 20, 2007Assignee: Shimano Inc.Inventor: Shinpei Okajima

Patent number: 7178239Abstract: A method intended for manufacturing a bicycle spoked wheel is described. 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.Type: GrantFiled: November 7, 2003Date of Patent: February 20, 2007Assignee: Campagnolo S.r.l.Inventors: Mario Meggiolan, Maurizio Passarotto

Patent number: 7140695Abstract: A rim for a bicycle has a lower bridge with infra-spoke zones of lower thickness than the thickness of the spoke attachment zones. The increase in thickness from the infra-spoke zones to the spoke attachment zones and the reduction in thickness between the spoke attachment zones and the infra-spoke zones have a sharp corner.Type: GrantFiled: June 25, 2004Date of Patent: November 28, 2006Assignee: Campagnolo S.r.l.Inventor: Maurizio Passarotto

Patent number: 7140696Abstract: An internal spoke nipple for a bicycle rim that is positioned internal to the rim and can be pivoted for alignment with various spoke angles. The internal spoke nipple is adapted to be positioned within an aero or deep V-shaped rim. The spoke nipple includes a cupped shaped base portion and a stem portion. The cupped base portion allows the internal spoke nipple to automatically align with the angle of the attached spoke, eliminating undesirable lateral forces on the spoke. The internal spoke nipple further comprises a fully threaded central bore that is adapted to engage and retain the spoke. The stem portion includes a plurality flat side walls that are adapted to accept a spoke wrench, to allow for adjustment of spoke tension.Type: GrantFiled: June 25, 2004Date of Patent: November 28, 2006Assignee: Trek Bicycle CorporationInventors: David Guzik, Steve Malchow

Patent number: 7137671Abstract: An element for the attachment of a spoke in a bicycle wheel at a seat hole has a body, an axial hole, and can engage a tool. The body is of greater transverse size than a seat hole, and abuts the seat hole at a first end of the body. The axial hole extends from the first end in the body and engages a spoke. The element engages a tool at a second end of the body opposite the first end. Finally, the maximum transverse size of said body is defined by side surface portions of said body other than the area of the second end that engages the tool.Type: GrantFiled: January 27, 2005Date of Patent: November 21, 2006Assignee: Campagnolo S.r.l.Inventors: Maurizio Passarotto, Davide Urbani

Patent number: 7104300Abstract: A sealing strip to be used with the rim of a wheel, particularly the rim of a so-called box section bicycle rim, as well as a rim equipped with such a sealing strip, and a wheel having such rim and sealing strip. The sealing strip is formed by a continuous annular strip having, in cross section, a median depression, forming a U-shaped radial groove provided to be positioned within in the central well of the rim, two lateral extensions provided to be supported upon on the interior edges of the rim that border of the well, and two lateral walls provided to extend along the flanges of the rim. The walls of the sealing strip are extended by a pair of lips that project toward the inside relative to the walls of the sealing strip, the lips being adapted to be positioned adjacent the lips of the rim.Type: GrantFiled: November 19, 2003Date of Patent: September 12, 2006Assignee: Salomon S.A.Inventors: Jean-Luc Veux, Gilles Parquet

Patent number: 7093910Abstract: A bicycle rim includes a plurality of recesses defined in an inner periphery thereof and a through hole is defined through the rim and shares a common axis with the recess corresponding thereto. A plurality of spokes each have a threaded hole defined in a first end thereof which is fitted in one of the recesses and a plurality of bolts extend through the through holes and are threadedly connected to the threaded holes in the spokes. The through holes are small so that they do not reduce the structural strength of the rim and the end of each spoke is fitted in the recess to further position the spokes to the rim. A second end of each of the spokes is connected to a hub by extending a bolt through the hub and threadedly connected to the second end of each spoke.Type: GrantFiled: December 8, 2004Date of Patent: August 22, 2006Inventors: Eric Alan Hjertberg, Douglas Chiang
