Abstract:
1. A bicycle or scooter compression clamp binding a handlebar stem tubing to a fork tubing assembly having a headset bearing such that the headset bearing can be preloaded via tightening of a compression mechanism, comprising: a longitudinal compression sleeve body; a first bore of a first diameter disposed at an end of the body, for engaging the handlebar stem tubing; a second bore of a smaller second diameter disposed at an other end of the body, for engaging the fork tubing assembly having a headset bearing, wherein the first bore and the second bore are substantially inline and coaxial to each other and meet within the body to form a circular lip defined by a difference in the first diameter and second diameter; a compression washer having a diameter greater than the second diameter, disposed upon the lip; a compression bolt with a head and threads coupled to the compression washer, the head within the first bore of the body and the threads within the second bore of the body; a gripping element coupled to the threads of the compression bolt, within the second bore of the body and adapted to grip an interior of the fork tubing of the fork tubing assembly inserted within the second bore of the body, such that as the compression bolt is tightened, the gripping element tightens against the inserted fork tubing such that it axially pulls the inserted fork tubing towards the compression washer to preload the headset bearing of the fork tubing assembly; a longitudinal slot along the entire body, providing a gap from the first and second bore to an exterior of the body; and a rotation preventing tightening mechanism disposed about a portion of the body on opposing sides of the longitudinal slot, such that as the tightening mechanism is tightened, the longitudinal slot is compressed and the handlebar stem tubing and the fork tubing assembly are secured to the body and prevented from rotating separately from the body.
