  • Patent number: 8973937
    Abstract: The present invention provides a shock absorber with compliant members. Shock absorption is provided by the bending and rebound of curved, flexible arms. The deflection and the damping capabilities of the shock absorber are determined by the dimensions, curvature, and material modulus of elasticity of these compliant members. The shock absorber with compliant members technology may be applied to a bicycle front fork shock absorber and a rear shock absorber, both described herein. The benefits of a shock absorber with compliant members are that it is light-weight, it is simple in design, it has few movable joints, it can be designed to have precise flexion and damping characteristics, and it is resilient in harsh conditions.

    Abstract: A one-piece connector for a shock-absorbing frame of a bicycle is manufactured by casting, forging or high pressure hydraulic forming means, is made of aluminum and formed as a single piece without welding, and has a bottom bracket shell, a connecting tube, a pivot and a linking joint. The connecting tube is formed on and protrudes from a top surface of the bottom bracket shell. The pivot is formed with the connecting tube near the bottom bracket shell. The linking joint is formed on an upper end of the connecting tube. The bottom bracket shell, the connecting tube, the pivot and the linking joint are formed with each other to form the one-piece connector without welding to simplify the production process, to improve the precision, quality and appearance of the one-piece connector, and to reinforce the structural strength of the one-piece connector.

  • Patent number: RE45503
    Abstract: A suspension structure includes a pair of right and left cushion units. The right cushion unit is constituted of a compression coil spring and a right damper, and the left cushion unit is constituted of only a left damper having an outer diameter smaller than a diameter of the compression coil spring and larger than a diameter of the right damper. The left cushion unit is constituted of only the left damper and does not include the compression coil spring and hence, the suspension structure can be simplified. Further, in the left cushion unit, the left damper does not slide relative to the compression coil spring in performing a stroke and hence, no friction is generated.
