ABSTRACT:
A collapsible and adjustable mechanic's platform which is suspended from a vehicle tire and supported on a pair of rails by chains which extend from the tops of the rails to brackets which support the platform. The rails are pivotally supported at their upper ends on short horizontal bars which are rigidly connected to a pair of vertical tire bars which, in use, are pressed against the outer wall of a vehicle tire by a combination of interconnected bars which extend over the top of the tire and down the inner wall of the tire. The interconnecting plates include a locking plate which is forced against the inner wall of the tire by a horizontal bar which extends across the top of the tire and through a circular opening in the locking plate. The horizontal bar which extends through the opening in the plate and the opening are sized so that the horizontal tire bar, which preferably has a rectangular cross-section, binds against the wall of the opening when the plane of the plate is tilted with respect to the axis of the bar.
