Multi-ring loose leaf binder and portable paper punch therefor

In a loose leaf binder including a cover having back and side panels and a binder post assembly mounted onto the back panel for holding a stack of loose leaf paper inside said cover, said binder post assembly including a multiplicity of binder rings adapted to pass through a plurality of spaced apart, prepunched holes provided in the loose leaf paper along a longitudinal edge thereof;

• the combination therewith of a portable paper punch comprising:
• (a) a pair of substantially flat, juxtaposed members, each of said members having therein a multiplicity of holes arranged in a pattern which is identical to the pattern of holes to be formed in the loose leaf paper;
• (b) means for securing said flat, juxtaposed members together in a fixed, spaced apart relation with the pattern of holes in one member registering with the pattern of holes in the opposite member, the arrangement being such that a sheet of loose leaf paper inserted in the space between said members can be punched with the same pattern of holes by forcing a sharp object through the corresponding pairs of holes in said members;
• and
• (c) means for removably attaching said pair of flat, juxtaposed members onto said binder post assembly.
