A scaffolding fitting and scaffolding safety measures incorporating the fitting
The scaffolding fitting is in the form of a spring back hinge assembly (10), which includes two clamps in the form of steel half couplers (12, 14). The half couplers (12, 14) are separated by a hinge arrangement formed from an upper stop (20) and a lower stop (30). First half coupler (12) is keyed to upper stop (20) by way of recess (26) (best seen in figure 1). A flat steel plate (50) is keyed to lower stop (30) by way of recess (36). Second half coupler (14) is attached to plate (50) by a nut and bolt (52). A compression spring (42) is held in compression on the end of bolt (40). The force exerted by spring (42) urges together two inclined contact surfaces (22, 32) of the stops (20, 30) to bias the hinge assembly to a rest position.
