Geomatic pole support with telescoping legs and locks

A leg for use in supporting geomatic equipment comprising

• a first leg section,
• a second leg section, the first leg section being telescopingly received into an interior of the second leg section for selective extension from and retraction into the second leg section to lengthen and shorten the leg,
• a locking device including an actuator and an engagement portion positioned to act on the interior of the second leg section to lock the first and second leg sections relative to each other to fix the length of the leg, the locking device being operable in a lock position in which the engagement portion of the locking device bears against the second leg section on the interior thereof with a force selected to lock the first and second leg sections, and an unlock position in which the actuator applies a force to the engagement portion of the locking device drawing it inwardly during movement of the actuator so that the engagement portion is everywhere spaced from the second leg section such that the leg sections are free to move in telescoping relation to change the length of the leg, the locking device comprising first and second opposing lock members, each of the lock members having a ramp surface thereon and wherein the actuator has two cams each being engaged with a respective ramp surface, and a wedge moveable relative to the lock members to move the lock members apart in the lock position and to allow the lock members to move closer together in the unlock position.
