A spoke receiving hole is perforated through a flange formed on a rim so as to incline by a predetermined angle in a radial direction with respect to a line perpendicular to a wheel center plane. A head of a spoke seats on a seating surface provided on one side surface of the spoke receiving hole in contact at a region I on the side closer to a rim body and a head straight portion of the spoke contacts with an edge portion K of an opening on the side distant from the rim body to which a hole portion directly opens on the opposite side from the seating surface of the spoke receiving hole.

A bead seat clincher bicycle rim includes a tire supporting surface bounded by a first straight sidewall and a second straight sidewall wherein said bicycle rim does not comprise bead hooks. A method for forming a bead seat clincher rim includes forming composite plies in a bottom portion of a mold and placing a single piece upper portion over the bottom portion. A bladder is inflated in the center of the mold to form a closed cavity within the rim. The rim is cured and the bladder is deflated. The single piece upper portion and bottom portion of the mold are removed.

A spoked wheel comprises a rim, a hub, wishbone shaped spokes, nipples, and eyelets. There is true pairing of the spokes, because the rim has half the number of spoke attachments as there are nipples. True paired spoking means that there are no side wobble forces or rim twist caused by spoke tension. The rim has spoke attachment holes that are parallel to the axis of wheel rotation and are reinforced with eyelets. The rim has unnecessary material cut away between the spoke attachment holes. To ease adjustment, the nipples are located about midway between the hub and the rim. The hub has longitudinal ribs and that are aligned with each other. That allows the hub body to be machined from a relatively lightweight extrusion. To increase the wheel strength, the inboard spokes are moved outboard as much as possible. The hub has pairs of nipple attachment holes where each pair is located on a diagonal relative to the axis of the hub.

A bicycle rim includes side portions with an outer portion extending between the side portions to form a pair of outer corners, and a spoke attachment portion. The outer portion includes a pair of ridges spaced from the outer corners. The ridges preferably divide a pair of inclined surfaces. The side portions preferably include a pair of ground braking surfaces with a pair of sloping surfaces extending from the braking surfaces to a pair of outer side surfaces.

A bicycle wheel basically has a hub, a plurality of spokes extending outwardly from the hub and an annular rim coupled to the outer ends of the spokes for supporting a tire. The annular rim has a spoke attachment portion with a plurality of spoke openings for receiving the outer ends of the spokes therein. The spoke openings of the annular rim have reinforcement members located between the spokes and annular rim. The outer ends of the spokes have bent sections located within the spoke holes of the reinforcement members or washers and head section that engage the inner surface of the reinforcement members. The rim is free of access apertures or holes in the outer annular portion adjacent a majority of the spoke holes. The reinforcement member has a transverse dimension allowing the outer end of the spoke and the reinforcement member to pass through the openings in a first orientation and be retained in the openings in a second orientation.

摘要:
A multi-part lightweight easily extruded or molded wheel rim and wheel particularly for cycling with joined flanges which extend radially inwardly toward the center of the rim and wheel provides strength not found in conventional channel shaped rims. The radially extending flanges are provided with apertures for receiving bent ends of spokes for assembling the rim and a hub to form a wheel which receives an inflatable tubeless or tube tire which need not be dismounted from the rim when repairing or replacing spokes.

A bicycle wheel includes a hub and a plurality of mounting seats arranged around the hub and pivoted to the hub for pivoting about axes parallel to an axis of the hub. A plurality of spokes have outer ends mounted on a wheel rim, and inner ends mounted on the mounting seats for mounting the wheel rim on the hub.

A bicycle hub is provided for use with bicycle spokes with spoke nipples threadedly coupled to their inner ends. The bicycle hub includes a hub axle and a hub body. The hub axle has a center axis extending between a first end and a second end. The hub body has a tubular center portion defining an interior passageway and a first mounting portion coupled to a first end of the center portion. The center portion defines an interior passageway with the hub axle being rotatably supported in the interior passageway. The first mounting portion has a plurality of first spoke openings extending axially to a first free edge and a plurality of first protrusions extending radially inwardly from the first mounting portion. The plurality of first protrusions are fixedly coupled to the first mounting portion. The bicycle hub also includes a second mounting portion coupled to a second end of the central portion. The second mounting portion has a plurality of second spoke openings. The second mounting portion can be different than the first mounting portion.
摘要:
A bicycle wheel basically has a hub, a plurality of spokes extending outwardly from the hub and an annular rim coupled to the outer ends of the spokes for supporting a tire. The annular rim has a spoke attachment portion with a plurality of openings and radially extending recesses for receiving the outer end portions of the spokes therein. The outer end portions of the spokes are at least partially recessed within the radially extending recesses to provide an aerodynamic design. The outer end portions of the spokes are preferably bent such that first sections of the spokes are offset from sections of the spokes. These bends are positioned in the openings of the rims to retain the outer ends of the spokes in the openings of the rim. In selected embodiments, the offset section between the first and second sections is either thicker or corrugated.
