Wheelchair with adjustable rear canes

A wheelchair comprising:

• a frame assembly including a lower frame portion and a back frame portion, the lower frame portion and back frame portion joined by an associated connecting structure, the back frame portion including two generally vertical tubular members, each generally vertical tubular member defining at least one mechanical fastener receiving aperture therein;
• an operator supporting means including a lower supporting portion operatively connected with the lower frame portion for supporting the operator and a back supporting portion operatively connected between the tubular members for supporting the operator's back;
• a pair of rear wheel mounting assemblies for selectively mounting a pair of rear wheels to the frame assembly;
• a pair of front wheel mounting assemblies for selectively mounting a pair of front wheels to the lower frame portion;
• and,
• a pair of L-shaped rear canes, each cane including:
• a first portion defining a hand grip and a second portion extending generally perpendicular to the first portion, the second cane portion defining a plurality of alternating apertures and score lines, the apertures being spaced at preselected regular intervals from each other, the score lines being spaced at said preselected intervals from each other to facilitate shortening the cane second portion by multiples of said preselected interval, the cane second portion being disposed in telescopic receipt with one of the generally vertical tubular members with one of the cane second portion apertures aligned with one of the generally vertical tubular member apertures, mechanical interconnection means between the associated connecting structures and the rear tubular members for limiting the telescopic receipt between the cane telescopic receipt portions and the rear tubular members, such that severing the cane telescopic receipt portions at corresponding ones of the score lines shortens the telescopic receipt portions and enables the hand grips to be positioned lower without interference from the associated connecting structures;
• and,
• a fastener extending through the aligned cane second portion and generally vertical tubular member apertures to fix the cane to the frame with the hand grip portion at one of a plurality of preselected heights.
