A folding wheelchair has side frames connected by front, rear and bottom toggle braces which in the folded position permit the side frames to come together. Each toggle brace is preferably formed from a pair of U-shaped elements hingeably connected at the base of the U, the toggle braces co-operating with the framework such that folding is initiated by lifting upwardly of the bottom toggle brace. This is best achieved by a rigid rod linking the front and rear toggle braces and carrying abutment element for engaging with the bottom toggle brace so that folding of the front and rear toggle braces cannot occur until the bottom toggle brace is lifted. The wheelchair may have at least one toggle brace of U-shaped members with the base of each U divided transversely to provide for relative rotational motion between the portions of each U-shaped member. The wheelchair may also have a novel folding footrest. |
