In combination with a wheelchair having a frame supported on a plurality of wheels and incorporating a central seat portion and a pair of opposite side forward frame portions adjacent a forward portion of said seat portion and between which the legs of a person seated on said seat portion extend, a horizontally elongated transverse support extending transversely of said wheelchair and including first and second ends equipped with first and second support means, respectively, said first support means and one of said forward frame portions including first coacting means supporting said first end from said one forward frame portion for oscillation relative to the latter about an upstanding axis and swinging of said support between a first “closed”position extending transversely of said wheelchair and between said forward frame portions and a second “open”position with said second end of said support swung forwardly from the other forward frame portion to a position extending forwardly from said one forward frame portion, said second support means and said other forward frame portion including second coacting support means operative to releasably latch said second end relative to said other forward frame portion with said support in said first position, said first support means including a depending support member carried by said first end of said transverse support and comprising a part of said first coacting means, said first coacting means also including a pair of vertically spaced bracket portions supported from said one forward frame portion and defining vertically registered and aligned openings formed therethrough, said support member being snuggly slidably and rotatably received through said openings, said depending support member and one of said bracket portions including coacting abutment means limiting downward sliding movement of said support member through said openings while allowing unrestricted upward sliding withdrawal of said depending support member through said openings, said second support means including a second support member depending from said second end of said transverse support and comprising a part of said second coacting means, said second coacting means also including a pair of upper and lower vertically spaced bracket portions supported from said other forward frame portion, said second support member including upper and lower portions horizontally registered with said upper and lower bracket portions of said other forward frame portion when said support is in said “closed position”, at least said lower bracket portion supported from said other forward frame portion and said lower portion of said second support member including abuttingly engaged portions preventing further swinging of said lower portion of said second support member past said “closed position”, said upper portion of said second support member and said upper bracket portion supported from said other forward frame portion including releasably relatively hook engaged portions thereof preventing downward movement of said upper portion of said second support member relative to said upper bracket portion supported from said other forward frame portion and swinging movement of said upper portion of said second support member relative to said upper bracket portion of said other forward frame portion from said “closed position”toward said “open position”.
