Abstract (en)
[origin: EP0413379A1] A paper punch comprises a base part (10) and a pressure lever (18) which is pivotally mounted on lateral pillow blocks on 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 (18) has two downwardly curved bearing lobes (28) which overlap the outside of the pillow blocks (14), and an apron (30) on the front face of the pressure lever (18) which curves downward in the region between the pillow blocks. Under the action of the restoring force of the spring (20), the apron (30) strikes against impact edges on the pillow blocks (14). To prevent parts of the hand being jammed, the impact edges are arranged on thin-walled extenders (40) of the pillow blocks (14) parallel to the bearing lobes (28), while the lateral edges of the apron (30) have a bend (34) in the vicinity of their lower edges, which together with the adjacent bearing lobe (28), delimits a narrow gap (38) the edges of which open toward the base part and in which the extender (40) engages.
