Abstract
A quick release mechanism for the mount/dismount head of a rim holding tire changer, including a wedge plate that overlies the top of the horizontal bar and has an opening in registry with the opening in the sleeve through which the vertical bar passes. The opening in the wedge plate is shaped to mate with the cross-sectional profile of the vertical bar and is only slightly larger than the size of the bar. Thus, when the wedge plate is horizontal so that the axis of the opening is aligned with the axis of the opening of the sleeve, the vertical bar will move freely up and down in response to pressure on the vertical bar. The wedge plate has protrusions on its under side on one side of the opening and the protrusions rest on the upper face of the sleeve. A actuation handle is attached to the underside of the wedge plate and depends perpendicularly from it. The actuation handle is arcuate so that it mates with the outer perimeter of the sleeve and when held against the sleeve, the axis of the opening of the wedge plate will be aligned with the axis of the opening of the sleeve and the bar will be free to move within the sleeve. On the end of the wedge plate opposite the actuation han…
