  • Patent number: 5213296
    Abstract: A connecting assembly for a tripod comprises a coupling pipe having a ferruled lower end with three radial lugs extending therefrom, and three legs having clevis connectors on their respective upper ends. The clevis connectors are hingedly attached to respective lugs by pivot pins engaged through registered holes thereon. An elongate locking bar is slidingly disposed in a rear cavity at the base of each connector. A compression spring urges each locking bar forward towards a selected locking recess formed on the periphery of an associated lug. A lever is pivotably secured within each connector, and has a first arm extending through an aperture on a first prong of the connector and a second arm resting against a transverse cavity in an associated locking bar. Each locking bar can be retracted from an engaged recess by squeezing the first arm of an associated lever towards its connector so as to allow the rotation of an associated leg to a new locking position about its lug.
