  • Publication number: 20120243931
    Abstract: A longitudinally adjustable assembly for a bicycle seat has a seat tube, a seat post and an auxiliary hoop device. The seat tube has an inner surface and multiple longitudinal grooves formed in the inner surface of the seat tube. The seat post is slidably inserted into the seat tube and has an outer surface and multiple protrusions. The protrusions are formed on and protrude out from the outer surface of the seat post. The protrusions are respectively slidably mounted in the longitudinal grooves to allow the seat post to longitudinally move along the seat tube. The auxiliary hoop device is mounted securely with the seat tube and around the seat post. Because the protrusions are slidably mounted in the longitudinal grooves and the auxiliary hoop device provides a pressing force for the seat post, a relative rotation between the seat post and the seat tube can be avoided.

  • Publication number: 20120160623
    Abstract: A cylinder assembly includes a piston rod connected to a piston which is movably received in a cylinder and the interior of the cylinder is defined into a first room and a second room by the piston. A first groove and a second groove are respectively defined in the inside and the outside of the piston, and the two grooves are longitudinally aligned with each other. Two seal rings are respectively engaged with the first and second grooves. The first groove includes a first inner surface and the second groove includes a second inner surface. A distance is defined between two respective extension lines of the first and second grooves. Each of the two respective extension lines is defined by extending a line from the first/second inner surface of the first/second groove. The outer diameter of the piston is reduced for being used with a smaller cylinder.

  • Patent number: 8197002
    Abstract: A seat adjustment device for a bike includes a holding base adapted to be engaged on a top of a support tube for a seat. First and second clamp blocks are received in the holding base. The second clamp block is moveable relative to the first clamp block. A bar-clamping space is formed between the first and second clamp blocks to clamp a support rod for the seat. An resilient member is provided between the first and second clamp blocks to bias the first and second clamp blocks towards an inner wall of the holding base. The first and second clamp blocks may be free to pivot around in the holding base, allowing the seat to be adjusted at a significantly increasing angle.

  • Publication number: 20120049427
    Abstract: A shock-absorbing device includes a first cylinder with a first room defined therein and a room is defined in an end of the first cylinder. A second cylinder extends into the first cylinder and has a first piston so as to define a third room and a third room. Hydraulic liquid is filled in the second and third rooms. A first tube and a second tube extending through the first tube are located in the first room. A first path and a second path communicate with the recess. The first and second tubes extend into the second cylinder and are connected to the first piston. When the first and second cylinders are relative moved, the hydraulic liquid is controlled to flow or not flow between the first and second paths so as to absorb different levels of shocks, and the speed that the shock-absorbing device returns can be adjusted.
