摘要:
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.

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.

A bicycle rim is provided that includes a tire attachment portion, a spoke attachment portion and a plurality of reinforcement members. The spoke attachment portion is fixedly coupled with the tire attachment portion. The spoke attachment portion includes a plurality of circumferentially spaced attachment openings. The reinforcement members are fixedly coupled to the spoke attachment portion at the attachment openings to effectively increase the thickness of the spoke attachment portion of the rim at the attachment openings. Each of the reinforcement members is bonded to the spoke attachment portion. The through openings are aligned with the attachment openings.

A bicycle wheel includes a rim with a plurality of holes defined therethrough and each hole receives an insertion section of a nut. The insertion section is enclosed by an inner periphery of the hole and an end surface of the insertion section is in flush with an inner periphery of the rim. A threaded hole is defined in the end surface of the insertion section. A plurality of spokes each have a threaded end at a first end thereof so as to be threadedly connected to the threaded hole of one of the nuts. A hooking end is connected at a second of each spoke so as to be connected to a hub.

A wheel rim includes two annular sidewalls and a main connecting wall. The main connecting wall has two ends connected respectively and fixedly to radial inner ends of the sidewalls, and opposite radially inner and outer surfaces. The radially inner surface faces the hub, and has two axial surface portions and a middle surface portion that are preferably concaved toward the tire. The radially outer surface has two axial surface portions and a middle portion. The axial surface portions of the radially inner and outer surfaces define two force-bearing areas having a plurality of mounting holes. The middle surface portions of the radially inner and outer surfaces define a weight-reducing area having a thickness smaller than a thickness of the force-bearing areas. The force-bearing areas and the weight-reducing area are arched.

The present disclosure includes a bicycle wheel having a hub, a plurality of spokes, and a rim. The spokes are connected to the hub, each spoke having two ends and a major axis. The ends of each spoke are substantially aligned with the major axis of such spoke. The rim provides a plurality of fixed spoke mounts secured to the spokes. The spoke mounts provide stress grading, in one preferred embodiment by decreasing in section as they extend away from the main body of the rim toward the hub. The spoke mounts are formed integrally with the rim and avoid the use of holes through the wall of the rim that seats the tube. Spoke adjustment mechanisms for straight spokes attached to such spoke mounts are also provided. The disclosure also includes a method of constructing a wheel.

A vehicle wheel spoke termination assembly includes an outer rim with means for holding a tire, a central hub assembly and a plurality of spoke portions. The central hub assembly includes an axle assembly and a hub shell that is rotatable about the axle. The spokes are connected at their outer ends to the outer rim hoop and at their inner ends to the hub flange. A connecting element is blindly attached to at least one of the outer rim and the hub flange for a firm connection between the connecting element and the spoke.

The invention relates to a tubeless mounted assembly for a cycle, more particularly for a bicycle, consisting of a rim and a tyre. A mounted assembly of the tubeless type for a cycle consists of a rim and of a tyre comprising in particular beads, said rim consisting of two wings, attached to two seats, intended to receive the beads of a tyre. According to the invention, the rim and/or the tyre comprises means for stabilising the pressure of the air at the level of the outer surface of the tyre, in the zones which are neither in contact with the ground nor in contact with the rim, to a value lower than 2 bar. The invention is directed also at a rim for a cycle wheel and a tubeless tyre for a cycle.

A bicycle rim includes a plurality of holes defined therethrough and each hole has a recess defined in an inner periphery of the rim. A diameter of the recess is larger than a diameter of the hole so that an end of a spoke is engaged with the recess. A screw extends through the hole in the rim and threadedly engaged with a threaded hole defined longitudinally in the end of the spoke.
