Abstract
A quick-release collar assembly for fastening weights onto a bar is disclosed. The assembly includes an annular collar defining a bore which enables the assembly to be slid onto the barbell and to snugly abut against the weights to be retained thereon. A lock shoe is disposed in a passage which communicates with the bore in the collar. A cam is provided which is reactive against the lock shoe and urges the lock shoe into retaining engagement with the bar when the cam is in a locked position. When the cam is in an unlocked position, a resilient spring acts to urge the lock shoe out of engagement with the bar, so that the collar can be easily removed from the bar. The cam is pivotally supported on a pivot shaft which incorporates a resilient bushing which is compressed when the cam is moved to the locked position. In another embodiment, the cam is reactive directly against the bar.
