ABSTRACT:
An improved freeweight locking mechanism employs a spring-biased lever having a locking end which blocks movement of the freeweight securing member from a first position whereby a weight is secured to a lifting bar and an operating end, which when contacted by the support frame for the weights, will cause the locking end to move a sufficient distance to allow movement of the weight-securing member to the release position. The member has a rib which defines two surfaces or shoulders to allow the member to be locked in either the weight-securing or weight-releasing positions. The movement of a weight away from the support frame allows spring bias to force the locking end of the lever into the locked position and this blocks accidental movement of the member from its weight-securing position.
