Abstract (en)
[origin: WO9102634A1] A paper punch comprises a base part (10) and a pressure lever (16) which is pivotally mounted on side bearers of the base part (10) and which acts, against the restoring force of a spring (28), on a hole punch slidingly guided on the base part (10). The pressure lever (16) has two lateral, convex downward-bearing lobes (28). The rearward edges (20) of each lobe overlaps in scissors fashion a rearward edge (22) of the side bearers (12). To prevent the fingers being jammed even if the punch is improperly handled, the rearward edges (20, 22) of the bearing lobes (18) and the side bearers (12) diverge and project beyond their instantaneous point of intersection by at least one finger's breadth and form a shearing angle of at least 50 DEG , over the whole pivoting range of the pressure lever (16).
