Scaffold and like structures

Claim 1

A locking assembly for use in interconnecting two members in builders scaffolding, which comprises a channel-shaped element having a base wall and side walls the ends of said side walls being fixable to one of said two members to be interconnected, and said base wall being inclined relative to said ends of said side walls, and a tapered wedge member mountable within said walls of said channel-shaped element to co-act with said base wall and, when in use and in its operative position, with a part of the other of said two members to be interconnected, said wedge member comprising a plate having first and second oppositely disposed wedging surfaces said first wedging surface co-acting with said base wall of said channel-shaped element and said second wedging surface co-acting with said part of the other of said two members to be interconnected, wherein said wedge member is of cranked formation to define an intermediate longitudinal bend lying parallel to said first wedging surface, said wedge member further being tapered from one end to the other to present an increased thckness at one end therof whereby, in use, movement of said wedge member from an operative positon into an inoperative position is such that said end of increased thickness engages the adjacent surfaces of said side walls of said channelshaped element and thereby causes said wedge member to be retained in said inoperative position.
