Claim 1
Independent Claim
217 words
A clamp is adapted to mount a table on a wheel chair having a pair of horizontally spaced vertically disposed tubular frame members, each having a horizontal tubular frame member intersecting and projecting therefrom with said horizontal members parallel to each other, said clamp comprising a pair of vertically disposed body members adapted to hold a table on said horizontal frame members adjacent said vertical frame members, a clamping member on each body member, pivot means pivotally mounting each clamping member to its respective body member so that the clamping member is disposed adjacent a vertical frame member, said clamping member having opposite vertical sides, each of which sides having a right angularly disposed tab thereon, said tabs on each clamping member vertically spaced on the clamping member and projecting towards the tabs on the other clamping member with the lower tab on each clamping member being disposed below its body member, whereby when the body members have their lower edges mounted on the horizontal frame members, each clamping member is pivoted to clamp the tabs on opposite sides of a vertical frame member with the lower tab disposed below the horizontal frame member to thereby secure the body member and a table carried thereby to the horizontal and vertical frame members against vertical and horizontal movement.
