Abstract
A folding tripod the legs of which are moveable into operative positions where they can be arrested to impart stability and firmness to the tripod, by clamping them against peripheral surfaces of brackets protruding from a center post of the tripod. Each bracket is provided with a bearing acting as a fulcrum for its associated leg, and with a peripheral surface surrounding the bearing, the surface having at least one portion which is closer to the bearing than other portions, whereby the legs tend to resist pivotal movement from an operative, load bearing position while permitting movement in an opposite direction to facilitate their release and subsequent storage.
