Patent ID: 8839725

Claim:
A table apparatus comprising: a support assembly configured to support the table apparatus relative to an outside surface; a surface assembly including at least one work surface; and an adjustment assembly coupling the support assembly to the surface assembly, the adjustment assembly comprising: a first rotational coupling having a pair of spaced apart support axles, the first rotational coupling attached to the support assembly; a second rotational coupling having a pair of spaced apart surface axles, the second rotational coupling attached to the surface assembly; a pair of linkages of substantially the same length, each having a first end and a second end, the first end of each linkage coupled to one of the spaced apart support axles of the first rotational coupling, the second end of each linkage coupled to one of the spaced apart surface axles of the second rotational coupling, wherein when coupled, the linkages are substantially parallel to each other throughout rotation of the linkages relative to the support axles and surface axles between a first bottom position and a second top position, whereby movement between the first bottom position and the second top position maintains the at least one work surface of the surface assembly in a substantially constant planar orientation; and wherein the adjustment assembly further comprises a handle assembly movably coupled to the support assembly and movably coupled to at least one linkage, whereupon selective movement of the handle member moves the surface assembly between the first bottom position and the second top position; and wherein the handle assembly further comprises a restraining assembly to maintain the surface assembly in a desired orientation relative to the support assembly, the restraining assembly having at least one actuator configured to selectively release the retention of the adjustment assembly relative to the support assembly.
