| 摘要 |
The invention provides a fast-deployable light-weight tripod, comprising a center support for supporting a load, provided with three peripheral hinge members, three multi-stage telescoping leg assemblies each attached to one of the hinge members, each leg assembly comprising at least two compression-resistant members interconnected by a telescopic joint, at least one cam locking unit associated with each telescopic joint, each locking unit having a first engaged position preventing relative axial movement which would shorten the length of the leg assembly, and a second disengaged position wherein the assemblies are free to move in either axial direction, each locking unit being urged towards its engaged position for automatic locking of the tripod in its deployed position with the cam locking being effected by pressure on the cam unit from its associated extended leg; and further comprising a hand accessible release element for each leg assembly for independently releasing the at least one cam locking unit associated therewith, thereby enabling the shortening of the length of the assembly. <IMAGE> |
