[origin: US5386638A] PCT No. PCT/EP92/00037 Sec. 371 Date Aug. 19, 1993 Sec. 102(e) Date Aug. 19, 1993 PCT Filed Jan. 10, 1992 PCT Pub. No. WO92/14589 PCT Pub. Date Mar. 9, 1992.A paper punch having a pair of pivotably mounted top struts and a pair of pivotably mounted bottom struts, with the pair of top struts being pivotably mounted to the pair of bottom struts. As mounted, the pairs of struts can fold against each other. Associated with each adjacent top and bottom strut is a die which moves through guide openings when the struts are moved into their operative position away from each other. A spring is situated between each adjacent top and bottom strut for biasing each adjacent top and bottom strut away from each other as the pairs of struts are moved in a direction opposite to their folding direction. One of the pairs of struts define slits for the reception of a paper sheet to be punched.
