Abstract: A light weight surveying pole which is of robust and highly accurate construction. A lock for fixing telescoping sections of the pole provides fixed positioning without high initial clamping forces. An air cushion system inhibits damaging the pole sections when they are retracted, but the pole sections can be simply pulled apart without any other required disassembly for cleaning or repair. Fittings for use in screw-together pole sections are constructed to permit location within mating pole sections prior to application of adhesive for greater precision and maintenance of coincident axes of the pole sections when screwed together. Also, the end faces of the fittings are particularly formed to facilitate complete face-to-face contact and avoid misalignment when the fittings are attached. A cover can be attached over a point of the surveying pole when the point it not needed, and the cover can be stowed on the surveying pole when the point is used.

Abstract: A light weight surveying pole which is of robust and highly accurate construction. The pole may include two or more pole sections which may be screwed together to make a longer pole. Fittings for use in screw-together pole sections are constructed to permit location within mating pole sections prior to application of adhesive for greater precision and maintenance of coincident axes of the pole sections when screwed together. Also, the end faces of the fittings are particularly formed to facilitate complete face-to-face contact and avoid misalignment when the pole sections are connected together.

Abstract: A support for surveying equipment and the like has telescoping legs and a locking system including a clamp for locking the legs in a selected position of extension. The two telescoping leg members making up each leg have wedge formations which engage over a wide surface when clamped together to facilitate locking. The clamp is formed to actively release from locking the leg members 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 of the legs 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 also holds the leg member to facilitate interlocking the leg members at a selected position of extension.

Abstract: A surveying equipment support leg used with a support for supporting surveying equipment and the like is capable of mounting alternate ground engaging structures without removal of an existing foot on the leg. Attachment of the alternate structure is made rigidly at two points of connection on the foot. Other accessories such as weights to hold down the support can be attached. In particular, a spike may be attached to deeply penetrate the ground for use in certain soil conditions. The foot is molded and accurately adhered to the leg. As used together with other legs in a support, the foot is capable of attaching the legs together in a collapsed position for storage and transport of the support. The leg is connected to a head of the support in a sealed hinge which prevents damage to the hinge resulting in loss of rigid stability to the support.
