  • Patent number: 6846047
    Abstract: An improved wheel rim, an improved spoke nipple and an improved wheel are disclosed. The rim has spoke openings and a threaded end of each spoke extends therethrough. An internal nipple with a threaded bore is connected to the threaded spoke end so that a first, ball-shaped, rounded end of the nipple is seated on the rim. A portion of the rim around each spoke opening is deformed or removed so as to define a portion of a socket with the same curvature as the first end of the nipple. This minimizes the required diameter of the spoke opening in the rim and maximizes the area of the rim socket surface. The invention also extends to an external nipple with a rounded collar in combination with a rim including a concave rounded rim surface formed in the rim itself.

  • Patent number: 6715844
    Abstract: An improved tensioned spoke bicycle wheel. The wheel comprises a hub, a rim, spokes and spoke nipples. A spoke that is connected to the left side of the hub is paired, at the rim, with a spoke that is connected to the right side of the hub. For each pair of spokes, there is provided a spoke plate that is positioned between the rim floor and the nipples. Each of the spokes in a pair extends through adjacent spoke bores in the rim, through spoke bores in the spoke plate and into the spoke nipples. The spoke plates distribute the forces associated with the tensioned spokes over a substantial portion of the rim floor. The spoke plate may have a flat surface where it supports the nipples or a socket shaped surface. In the latter case, the nipples have a ball shaped lower end that seat in the socket.

  • Patent number: 6244667
    Abstract: An improved bicycle wheel is disclosed in which spokes (22) and spoke bores (18) are paired at the flanges of the hub (12) and the circumferential distance between adjacent pairs is grater than the distance between the spokes and the bores in a given pair, providing improved torque transmission and reduced spoke stresses at spoke crossover points. Such a wheel may be constructed to have reduced dish by comparison with a conventionally laced wheel. In this case, the wheel is one which, when laced conventionally, would be dished such as a rear wheel with at least one sprocket or a front wheel with a brake disk. In a rear wheel embodiment, the spokes extend from inside to outside, through a proximate hub flange and along the outside to inside through the opposed hub flange. In a front wheel embodiment, the spokes extend from inside to outside through the proximate hub flange along an inside or disk surface thereof.

  • Patent number: 6145938
    Abstract: Improvements in torque transmitting wheels are disclosed. The improvements afford more balanced torque transmission as between the proximal spokes, adjacent to a torque transmitting member, such as a sprocket, sprocket cluster or disc for a brake, and the distal spokes which are opposite from the torque transmitting member. A wheel according to the present invention is provided with radially oriented proximal spokes and tangentially oriented distal spokes. This shifts the majority of the torque transmission task to the distal spokes which, in a torque transmitting wheel, are under less tension than proximal spokes under static conditions. A torque transmitting member is mounted on the hub, adjacent the proximal hub flange, and the distance from the proximal hub flange to a plane through the proximal edge of the rim is substantially less than the corresponding distance from the distal hub flange.

  • Patent number: 5938293
    Abstract: Improvements in rear bicycle wheels are disclosed. The improvements afford more balanced torque transmission as between the proximal spokes, adjacent to the multiple sprockets and the distal spokes which are opposite from the sprockets. In one embodiment, torque balancing is achieved by providing the hub with a distal hub flange which has a diameter which is substantially larger than the proximal hub flange. Excellent results have been achieved in a wheel with a hub having a proximal hub flange with a diameter of X and a distal hub flange with a diameter of approximately 1.5 X. According to another embodiment, a wheel according to the present invention is provided with radially oriented proximal spokes and tangentially oriented distal spokes. This shifts the majority of the torque transmission tasks to the distal spokes which, as noted above, are under less tension than proximal spokes under static conditions.
