Intravenous bottle support arm

Claim 1

A support device comprising a wall mounting bracket, a horizontal linear extension linkage supported at its proximate end in said wall mounting bracket for swinging about a vertical axis and having a distal end restricted to a linear horizontal movement between a retracted position adjacent said proximate end and an extended position remote from said proximate end, said linkage comprising a pair of end to end proximate and distal parallelogram linkages, means connecting said parallelogram linkages at their adjacent upper ends, said parallelogram linkages depending from said connecting means and means coupling said parallelogram linkages to restrict the parallelogram linkages to similar corresponding opposite movements, said parallelogram linkages being in vertical juxtaposition with said connecting means being uppermost when said extension linkage is fully retracted, a support arm mounted to the bottom distal end of said distal parallelogram linkage and extending upwardly therefrom and being angularly adjustable about a horizontal axis transverse to the direction of extension of said extension linkage proximate to the inner end of said arm and independently of the extended position of said horizontal linear extension linkage, said arm being juxtapositioned to said distal parallelogram linkage when said extension linkage is fully retracted and said arm is adjusted to a fully retracted vertical position, spring means resiliently urging said support arm to a vertical position, means on said support arm releasably locking said support arm in a preselected angular position, said locking means comprises a vertical plate mounted at said linkage distal end and having an arcuate indexing edge coaxial with said support arm horizontal adjustment axis and a locking element mounted on and swingable with said support arm and selectively adjustable into and out of locked engagement with said indexing edge, and a bottle support member located on said support arm proximate its outer end.
