SURVEYING EQUIPMENT SUPPORT HAVING TELESCOPING LEGS

摘要

A support (10) for surveying equipment and the like has telescoping legs (14) and a locking system including a clamp (32) for locking the legs in a selected position of extension. The two telescoping leg members (16, 18) making up each leg have wedge formations (58, 60) which engage over a wide surface when clamped together to facilitate locking. The clamp (32) is formed to actively release from locking the leg members (16, 18) which the clamp is unlocked. The leg members are particularly constructed to permit surveying tools or other objects to be permanently or replaceably mounted on the legs. A hinge connection (64) of the legs (16, 18) permits them to pivot together in a collapsed position is formed in a unitary fashion with one of the leg members for additional strength. The hinge (64) also holds the leg member to facilitate interlocking the leg members at a selected position of extension.
