Abstract
Abstract A tripod leg is provided which distributes a portion of the forces produced by the supported object. These forces are directed substantially away from the means used to releasably hold the relatively movable members. Thus, a pair of parallel rods of a leg are separated by a first and second spacer. A third rod is attached to one spacer and extends between two parallel rods. A lower hollow member of the leg is inserted through a hole in the lowermost spacer and engages the third rod. Secured to the lower rod is a collar having a screw means for engaging and releasably holding the third rod.

Claim 1
Independent Claim
189 words
A support leg of the type used as part of a tripod, said tripod having a seat with leg engaging bosses extending therefrom, said leg comprising: a. a pair of spaced, rod-like members being pivotally securable at one end to the tripod bosses; b. first spacer means secured to said rod-like members substantially at the end opposed to said end being pivotally securable and having an aperture therethrough; c. second spacer means secured to said rod-like members intermediate said first spacer and said pivotal end; d. a third rod-like member secured to said second spacer and disposed between said first and second spacers and said pair of rod-like members; e. a fourth rod-like member slidable through said aperture and engaging said third rod-like member between said first and second spacers and said pair of rod-like members, the end of said fourth rod-like member extending beyond said pair of rod-like members and said first and second spacers and comprising foot means for standing said leg against the ground; and f. engaging means located between said first and second spacer means for adjustably securing said third rod to said fourth rod.
Claim 2
Dependent Claim
189 words
A support leg of the type used as part of a tripod, said tripod having a seat with leg engaging bosses extending therefrom, said leg comprising: a. a pair of spaced, rod-like members being pivotally securable at one end to the tripod bosses; b. first spacer means secured to said rod-like members substantially at the end opposed to said end being pivotally securable and having an aperture therethrough; c. second spacer means secured to said rod-like members intermediate said first spacer and said pivotal end; d. a third rod-like member secured to said second spacer and disposed between said first and second spacers and said pair of rod-like members; e. a fourth rod-like member slidable through said aperture and engaging said third rod-like member between said first and second spacers and said pair of rod-like members, the end of said fourth rod-like member extending beyond said pair of rod-like members and said first and second spacers and comprising foot means for standing said leg against the ground; and f. engaging means located between said first and second spacer means for adjustably securing said third rod to said fourth rod.
Claim 3
Dependent Claim
