Abstract

An adjustable table assembly comprising a planar work surface which is pivotally secured at the rear edge thereof to a pair of parallel, laterally spaced, vertical support members such that the work surface can be moved substantially continuously between a fully horizontal, extended position and a fully vertical, retracted position. Unique brackets attach the rear ends of upper and lower linkage bars to the support members with the brackets and support members being configured for cooperative, mating engagement whereby the brackets are adjustably longitudinally slidable upon the support members. The forward brackets attaching the forward ends of the lower linkage bars to the upper linkage bars are also configured for adjustable, longitudinal sliding engagement therewith.

Dependent claims

An adjustable table assembly comprising:

a) first and second, elongated support members each having first and second channels including respective first and second channel openings extending inwardly toward each other along opposite sides of substantially the entire longitudinal lengths of said first and second support members, and further including means for fixing said first and second support members in vertical and laterally spaced, parallel relationship to each other;
b) first and second upper linkage bars each having respective forward and rear ends;
c) first and second lower linkage bars each having respective forward and rear ends;
d) a substantially planar work surface of predetermined outline having top and bottom, opposite planar surfaces and parallel and spaced forward and rear edges, said first and second upper linkage bars attached to said bottom planar surface in laterally spaced, parallel relationship to each other and perpendicular to said forward and rear edges, said rear ends of said first and second upper linkage bars extending beyond said rear edge of said planar work surface;
e) first and second upper brackets each having first and second portions, said rear ends of said first and second upper linkage bars pivotally attached to said first portions of said first and second upper brackets, respectively, said second portions of said first and second upper brackets positioned in sliding, mating engagement with said first and second channels of said first and second support members, respectively;
f) first and second lower brackets each having first and second portions, said rear ends of said first and second lower linkage bars pivotally attached to said first portions of said first and second lower brackets, respectively, said second portions of said first and second lower brackets positioned in sliding, mating engagement with said first and second channels of said first and second support members, respectively, at positions below said first and second upper brackets on said first and second support members, respectively;
g) first and second forward brackets each having first and second portions, respectively, said forward ends of said first and second lower linkage bars being pivotally attached to said first portions of said first and second forward brackets, respectively;
and
h) means removably attaching said second portions of said first and second forward brackets to said first and second upper linkage bars in longitudinally sliding engagement therewith.
