Abstract
A load-carrying dolly having four wheels () adjacent the corners of its platform () is rendered immobile by conversion to a pallet-like condition by lowering bearers () into contact with the floor or ground () and then raising the platform () slightly to raise the wheels () clear of the floor or ground by means of either of two pedals (), one below each end of the platform (), with linkage (of either of two forms, not shown) to bars () connecting in 'slave' pairs of toggle links () by means of which the bearers are suspended through beams () connecting upward extensions () at the ends of the bearers (), the toggle links in each pair becoming locked by mating abutments () coming together when the links have passed slightly beyond in-line position, the mechanical advantage of the depressed pedal (or) being amplified by that of the pairs of toggle links when passing through in-line positions.
