ABSTRACT:
A holder for supporting a piece of equipment above a surface has a column fixed to the surface, projecting upward therefrom, and having an upper end defining an inner horizontal pivot axis, an inner arm having an inner end pivoted at the inner axis on the column and an outer end defining an outer horizontal pivot axis, and an outer arm having an inner end pivoted at the outer axis on the inner-arm outer end and an outer end provided with a support for the piece of equipment. A link has an inner end seated in the upper end of the column at a location spaced a predetermined relatively long distance from the inner axis and an outer end seated in the inner end of the outer arm at a location space a predetermined relatively short distance from the outer axis. Thus as the inner axis is lifted the angle formed between the support and the horizontal increases.
