Fitting device for accessory
First Claim
1. A fitting device for an ornamental accessory comprising:
- a pair of connecting members each having a cylindrical portion on an end to be fitted together in a rotatable manner relative to each other;
one of said connecting members having at its fitting end at least one piece of guide groove, said guide groove comprising a thrust groove which is open into an outside and extends in an axial direction of said connecting member, a rotation groove which bends from an inner end of said thrust groove and extends in a circumferential direction, and a fixing groove which bends from that end of said rotation groove which is away from said thrust groove towards said fitting end;
the other of said connecting members having at its fitting end a projection which is thrusted into said thrust groove and moves along said rotation groove, said projection being positioned to correspond to said guide groove;
each of said connecting members having inside its fitting end portion magnet pieces disposed on a plane, said magnet pieces having N pole and S pole arranged to lie alternately in a circumferential direction, thereby forming a magnetized surface facing outwards.

Abstract
A fitting device for an ornamental accessory is made up of a pair of connecting members each having a cylindrical portion on an end to be fitted together in a rotatable manner relative to each other. One of the connecting members has at its fitting end at least one piece of guide grooves formed in series. The guide groove is made up of a thrust groove which is open into an outside and extends in an axial direction of the connecting member, a rotation groove which bends from an inner end of the thrust groove and extends in a circumferential direction, and a fixing groove which bends from that end of the rotation groove which is away from the thrust groove towards the fitting end. The other of the connecting members has at its fitting end a projection which is thrusted into the thrust groove and moves along the rotation groove. The projection is positioned to correspond to the guide groove. Each of the connecting members has inside its fitting end portion magnet pieces disposed on a plane. The magnet pieces have N pole and S pole arranged to lie alternately in a circumferential direction to form magnetized surfaces facing outwards.
