  • Patent number: 6068347
    Abstract: 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 for receiving the outer ends of the spokes therein. The outer ends of the spokes are 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. Optionally, an adhesive may be used to more securely retain the outer ends of the spokes in the openings of the rim. In certain embodiments, the spoke attachment portion of the rim can be constructed of individually spaced elements which can be either fastened to the rim or unitary part of the rim.

  • Patent number: 6068348
    Abstract: 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.

  • Patent number: 5924328
    Abstract: The braking device of the present invention is equipped with a resistance element which acts so that, when the brake device is operated by pulling a brake lever to a set operating position where the wheel braking force produced by brake shoes reaches a certain set value, a discretely increased force resists operation of the brake lever so that further operation of said brake lever is inhibited until a pulling force which is greater than the resistance force is thereafter applied to the brake lever.

  • Patent number: 5915821
    Abstract: A snowboard boot includes a toe portion, a heel portion and a leg portion. The heel portion and the leg portion are coupled so that the leg portion is capable of inclination in a longitudinal direction relative to the heel portion, and/or the heel portion and the leg portion are coupled so that the leg portion is capable of inclination in a lateral direction relative to the heel portion. In a more specific embodiment, a rigid heel overlap member is coupled to the heel portion, and a rigid leg overlap member is coupled to the leg portion. The heel overlap member and the leg overlap member overlap in a longitudinal direction. The heel overlap member and the leg overlap member are capable of relative movement in a vertical direction and/or rotation around a longitudinal axis. If desired, the heel overlap member and the leg overlap may interface through an arcuate or approximately spherical surface to facilitate relative movement in the desired directions.

  • Patent number: 5909946
    Abstract: The invention relates to a shoe lacing configuration where short straps attached to sides of an article of footwear are formed with loops. At least one long strap extends through the loops in the one pair of the short straps, the long strap extending from side to side of the article of footwear. The long strap is further formed with loops at either end thereof. A lace extends through the loops in the long strap. The long strap has the effect of doubling the force applied to the lace on the short straps in a manner similar to that of a block and tackle thus improving the lace tightening characteristics of the article of footwear.

  • Patent number: 5704139
    Abstract: A sole for a snowboard boot includes a depression defined in the sole for attachment of a fastener and a recessed groove for providing a space which opens to the front of the boot for creating a through-passage between the space and the depression. The open space allows the boot to be easily attached to the snowboard while preventing direct contact between the fastener and the ground. A portion of the sole which includes the toe and recessed groove is more resilient than a remaining portion of the boot to further facilitate walking by allowing the sole to flex during walking.
