ADJUSTABLE PLIERS Adjustable pliers (2) comprising two arms (4,6) each with jaws (8,10) and handles (12, 14). One arm (4) has an elongate slot (20) with a plurality of spaced apart apertures (26a-26h, 32a-32h). The other arm (6) has a pivot member (50) with a profiled section (56) through the slot (20) to connect the arms (4,6). The profiled section (56) has a convex curved shape in 5 cross-section having opposing convex curved locking faces (56a, 56f) and convex curved free faces (56b-56e, 56g-56j) separating the locking faces and recessed within the notional outer perimeter (56k) of the profiled section. The arms are pivotable to cause either engagement of the locking faces with one of the apertures to determine the opening of the jaws or disengagement of the locking faces to allow movement of the pivot member along the slot to .o vary the opening of the jaws (8,10). The profiled section (56) has a generally curved trapezoidal shape in cross-section tapering towards the locking face (56f). Figure 5 Fig. 1A / 2 |
