Abstract
A lock mechanism which can be placed on a shaft, such as a bar or pole, in either a first direction or second direction, is secured to the shaft using two sets of balls which project out of apertures in an inner cylinder to frictionally engage the shaft. The balls are selectively retractable from their projecting position to allow the inner cylinder to slide on and/or be removed from the shaft. Biasing members, such as wavy springs, bias the two sides of the lock mechanism towards one another. In the locked configuration, the balls are forced by inclined surfaces within the two sides to project outwardly from the inner hollow cylinder. The inclined surfaces are aligned with two rows of apertures in the inner hollow cylinder, and they are inclined in opposite directions. Thus, either way the lock mechanism is installed or placed on the shaft, the balls will project out of the apertures in the inner hollow cylinder and will securely engage the shaft.
IPC Classes ?
- A63B 21/072 - Dumb-bells, bar-bells or the like
- F16B 2/16 - Clamps, i.e. with gripping action effected by positive means other than the inherent resistance to deformation of the material of the fastening using rollers or balls
