发明名称 BINDING TOOL
摘要 <P>PROBLEM TO BE SOLVED: To provide a binding tool which is unlikely to be separated when vibration or impact is applied, and which is relatively easily taken out since it is easily prevented that too much space is taken and some allowance can be secured in a chest pocket. <P>SOLUTION: A helical coil 3 made of a synthetic resin including an engagement projection 2 is provided to a flat surface 29 of a lower end 15 in the longitudinal direction. A buckle 5 having an insertion hole 4 for inserting the helical coil 3 is provided. A lock piece 6 for locking the engagement projection 2 is provided on the wall surface of the insertion hole 4. A first projection piece is integrally provided to an upper end in the longitudinal direction of the helical coil 3. The helical coil 3 is inserted through holes of a plurality of paper sheets on which the holes are punched with a constant interval. The first projection piece comes in contact with the paper sheets by the helical coil 3 being inserted through the holes, and thereby a move of the helical coil 3 in a direction of insertion is regulated. The engagement projection 2 inserted through the holes is inserted in the insertion hole 4 and locked by the lock piece 6, and thereby a move of the helical coil 3 in a direction of return is regulated and the plurality of paper sheets can be bound. <P>COPYRIGHT: (C)2012,JPO&INPIT
