ABSTRACT:
A walking aid for handicapped persons comprises a collapsible frame having a first pair of support members pivotally connected to each other approximately at their mid-points for executing a scissor action when the frame is to be collapsed. A second pair of support members are coupled to the upper portions of the members of the first pair by hinged joints each having two axes of rotation, and in the operative state are spaced from the first pair of support members by hinged bracing struts. A centrally hinged transverse bracing member holds the hinged joints and patient support handles apart in the operative state. The frame is collapsed by folding the transverse bracing member and bringing the handles together, thereby causing the first pair of support members to execute a scissor action which automatically brings the rear feet towards the front feet, resulting in particularly compact collapsed structure.
