Abstract

See full text

A collapsible support and shopping walker includes eight tubes of equal length that pivot in eight corner supports forming four cross braces. This four-sided cage can then flex in one direction from being fully collapsed to fully extended. Flexible fabric is attached across four corners to this cage allowing it to open about half-way between the collapsed state and full extension and can now be used as a seat. Collapsible diagonal supports, hinged at each end, form a “spider” which provides stability and enables easy opening and closing of the cage by moving the spider head up and down. In order to provide a stable chair or walker the spider must be lockable with the seat in the open position. This is arranged by letting the spider over toggle which stretches the fabric fully and tightens all the joints of the chair.
