摘要:A right-angle scaffold coupler comprises two jaw assemblies (10A, 10B) eachwith jaws formed by a closure-plate (12) hinged to a common chassis (11), and having ahand lever (14) hinged (at 21) to the plate (12) with a spirally-coiled spring (25, Figure 4)as hinge-pin within interleaved finger-lugs (26, 27). A hook-member (15) hinged to thelever (14) engages a lip (19) of the chassis (11) so that depression of the lever (14) pullsthe plate (12) towards the chassis (11) in closing the jaws onto a scaffolding tube (13) andclamping to it by over-centre action. The spring (25) coils up more tightly during theover-centre action allowing resilient displacement between the lugs (26, 27) of hinge (21)to accommodate variations in tube circumference. The jaw surface (17) of the chassis (11)subtends more than 180 degrees to snap fit with the tube (13).
