  • Patent number: 9193406
    Abstract: An angle adjusting device for a bicycle saddle is disclosed. The device includes a frame coupling block, which is coupled at a lower end thereof to an upper portion of a height adjustment unit. A saddle coupling post is coupled at a lower end thereof to an upper end of the frame coupling block and is coupled at an upper end thereof to the saddle, with a through hole formed in the upper portion of the saddle coupling post. An angle fixing unit includes a pair of fan-shaped plates attached to left and right sides of the frame coupling block, and a pair of rectangular plates coupling front and rear edges of the fan-shaped plates to each other. An angle adjusting unit is coupled to the saddle coupling post, and is detachable from holes in the angle fixing unit to control the rotation of the saddle coupling post.

  • Patent number: 8668262
    Abstract: An angle adjuster for a bicycle seat that is disposed between a frame of a vehicle and a seat. The angle adjuster for a bicycle seat includes: a frame connector configured to be connected with the frame; a seat connector configured to support the seat, rotatably connected to the upper end of the frame connector, and having a nose at bottom facing the frame connector; an angle adjusting assembly disposed between the frame connector and the seat connector, and having a plurality of locking steps where the nose is configured to be selectively engaged to control rotational angle of the seat connector; an operating lever configured to be mounted on the frame to operate the angle adjusting assembly; and a wire connecting the angle adjusting assembly with the operating lever and reciprocating the angle adjusting assembly, when the operating lever is operated.

  • Patent number: 8485597
    Abstract: The present invention provides an angle adjustment device for a bicycle saddle which can adjust the angle of the saddle even when the bicycle is moving. The angle adjustment device includes a movable unit (110), a stationary unit (120) and a locking unit (130). The movable unit is coupled to the saddle. The stationary unit is coupled to the movable unit and rotatably supports the movable unit when the angle of the bicycle saddle is adjusted. The locking unit releasably holds the movable unit, so that when the locking unit releases the movable unit, the movable unit is allowed to rotate and adjust the angle of the bicycle saddle, and when the locking unit holds the movable unit, the movable unit is prevented from rotating so as to maintain the angle of the bicycle saddle.
