Abstract: A leg for use in supporting geometric equipment includes a first leg section and a second leg section for telescoping receiving the first leg section. A locking device includes an actuator and an engagement portion. The locking device is operable in a lock position in which the engagement portion bears against the second leg section on the interior thereof with a force selected to lock the first and second leg sections with respect to each other, and an unlock position in which the engagement portion is spaced from the second leg section such that the leg sections are free to move in telescoping relation with respect to each other.

Abstract: A support for geomatic equipment such as a geomatic pole has feet which facilitate stability of the pole. The feet are constructed to resist forces applied along legs of the support to which they are connected in both directions, including forces which tend to lift the feet upward. The foot is formed to readily penetrate certain surfaces and to resist withdrawal from the surfaces after penetration. In one embodiment, a fixed connection to the underlying surface may be achieved. The foot is also constructed to resist rotation of the foot and leg to which it is attached which could cause instability of the support.

Abstract: A support particularly adapted for supporting a geomatic pole has telescoping legs, each having telescoping leg sections which can be locked by a locking device in a selected position of extension, fixing the length of the leg. The locking device is easily actuated and released and is biased toward a locked position. In an unlocked position, the locking device is positively positioned to inhibit contact with the released leg section so that movement is smooth and unnecessary wear is limited. The locking device has an engagement portion which is constructed to promote locking, but also to facilitate release and limit unnecessary wear of the engagement portion.
