Abstract
A tripod leg has upper and lower portions with the upper portion being secured at its upper end to the tripod head and having a housing guide at its lower end. The lower leg portion slides in the housing guide to adjust the total length of the leg. The lower leg portion is firmly clamped to minimize bending deflection. A strip of teeth on the lower leg portion are selectively engaged by elements on a locking block in the housing guide to fix the leg length, and the locking block is controlled from the top of the upper leg portion. Each leg of the tripod can be adjusted separately, or all three legs can be simultaneously adjusted. An over-centering, biased toggle linkage in the housing guide moves the locking block so that the clamping engagement is positive.
