    • PROBLEM TO BE SOLVED: To provide a pin folding fastener, applicable to pierced earrings, earrings, a brooch, a pendant and the like.
      SOLUTION: The pin folding fastener includes: a pin 1, the base end of which is provided with a shaft laterally projecting at right angles; and a base body 5 welded to an ornament, wherein the shaft is rotatably fitted to the upper part of the base body 5. The base end is a pin angle setting portion constituting two right-angled surfaces A, B to the base body 5, and a chain passing portion 4 is provided in the vicinity of the angle setting portion. A spring 6 and a metal pusher 7 are mounted in the base body 5, and the metal pusher 7 is urged upward by the spring 6, so that the top of the metal pusher 7 resiliently abuts against the angle setting portion. When the pin 1 is turned to bring the metal pusher 7 into contact with the right-angled surface A, the pin 1 is turned down along the base body 5, and when the metal pusher 7 comes into contact with the right-angled surface B, the pin 1 is raised at right angles from the base body 5. The pin 1 is retained in the respective positions by resilient force of the spring.

    • 要解决的问题:提供适用于穿孔耳环,耳环,胸针,吊坠等的销折叠紧固件。 销折叠紧固件包括:销1,其基端设有横向突出的直角的轴; 以及焊接到装饰件的基体5,其中轴可旋转地装配到基体5的上部。基端是构成基体5的两个直角表面A,B的销角设定部, 并且在角度设定部附近设置有链条通过部4。 弹簧6和金属推动器7安装在基体5中,金属推动器7被弹簧6向上推动,使得金属推动器7的顶部弹性抵靠角度设定部分。 当销1转动以使金属推动器7与直角表面A接触时,销1沿着基体5向下转动,并且当金属推动器7与直角表面B接触时 销1从基体5成直角地升高。销1通过弹簧的弹力保持在各自的位置上。 版权所有(C)2011,JPO&INPIT
