Description

  The present invention relates to accessories such as necklaces and pendants attached to the neck, bracelets attached to the arms, and anklets attached to the feet, and relates to fasteners for the accessories which allow the accessories to be attached to the corresponding position very easily.

In general accessories such as necklaces, pendants, bracelets and anklets, fasteners are used which are formed into a circular pipe and into which a spring is loaded. A fastener called a pull ring can be relatively used at a relatively low cost, and thus is used frequently.
However, since this fastener is very small and the operation is also performed with a part of the fingertip, its operability and feeling of use are very bad, and it can not be used by the elderly.

Therefore, in a state where the first bonding surface of the first base and the second bonding surface of the second base are combined as shown in JP 2013-102948 (see Patent 1), the first engaging portion and the first The first main body and the second main body are fastened to each other by the engagement of the two engaging portions and the regions of mutually different polarities being combined between the pole face of the first magnet and the pole face of the second magnet. Fasteners that are configured to be used are known.
However, in the invention of Patent Document 1, the connection between the first substrate and the second substrate substantially depends on the adsorption force of the magnet, so the fixing strength of the accessory is poor, and the problem has not been solved.

  In addition, a connecting fitting such as a necklace or a bracelet, which is used in an annular shape, as shown in Japanese Patent Laid-Open No. 11-235220 (see Patent Document 2), is connected with a magnetic body to connect open ends of accessories. 1 and 2 forming a bonding surface, indenting a magnetic body for adsorbing each other on the first and second bonding surfaces, and hooking the first and second bonding surfaces on each other There is also proposed a connection fitting constructed by providing a hooking piece of the shape and providing a recess of the first and second hooking pieces at axial end portions of the first and second joint surfaces. .

However, in the invention of Patent Document 2, two magnets, one for each of the first and second joint surfaces, are used. And, since there are two positions on the both sides of the magnet which are manually aligned before the magnet is in the attracted state, the first and second joint surfaces are positioned in combination with the fact that the magnets are only a pair facing each other. There was a problem that it was difficult to match.
In any case, each prior art has a structure in which it is difficult to add a unique design or decoration to the joining member to be joined.
