| 摘要 | PURPOSE: To facilitate use of one key selected form among the same sort of ring pieces, by movably coupling together the constituent members in such a way as confronting one another using eyelets furnished at the protrusive end of the outer sector and allowing this coupling to constitute a folding member coupling the ring pieces threaded through the eyelets. CONSTITUTION: Each constituent member 1 is made capable of folding by rotating in one direction for the shape of sectors 2 and 3 coupled together so as to be folding along a hinge 4. When two such constituent members 1 are folded to each other and put in the closing position where a dint 10 to accommodate each key 11 is formed inside, it is possible to open the constituent member 1 by pulling in the direction of arrow 12. In this process of opening, the eyelet 6 or 6' traces the curve of ring pieces 7, 8 or 9, so that the constituent members 1 are opened forcedly and comply with the direction of arrow 13. When the maximum opening is attained, the key 11 is exposed completely from the constituent members 1. If rotated to the closed position again, the constituent members 1 are returned to the initial opposing positions. In this new position closed, the keys 14 are gathered together and accommodated in the dint 10. | ||||||
