DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a finger ring comprising an outer ring and an inner ring and, more particularly, to a finger ring, the outer ring of which is held in suspension by the repellent force of magnets.
PRIOR ART
The finger ring as an accessory is available in a broad assortment including expensive rings to low-priced rings. Even toy rings are available for children. However, they are mere accessories or toys and have no other functions.
The present invention has for its object to provide a double-ring finger ring which, in addition to the conventional ornamental value, offers the fun of toying with and the benefit of diversion.
DISCLOSURE OF THE INVENTION
The finger ring according to this invention comprises an outer ring, an inner ring, and a plurality of magnets secured to the outer circumferential region of the inner ring and the inner circumferential region of the outer ring, respectively.
The magnets of the inner ring and the magnets of the outer ring are preferably disposed circumferentially in such a manner that all the magnets that may form pairs mate concurrently. Furthermore, the magnets of the inner ring and the magnets of the outer ring are preferably oriented alike in polarity, in which case the outer ring can be held in suspension.
The inner ring preferably has an extension at either axial end, in which case the outer ring is precluded from being completely disengaged from the inner ring. More preferably, said extension is continual in the circumferential direction, in which case not only the disengagement of the outer ring can be positively prevented but also the aesthetic value of the finger ring is improved.

BEST MODE FOR CARRYING OUT THE INVENTION
The present invention is now described in further detail with reference to the preferred embodiments illustrated in several views of the accompanying drawing.
Referring to FIG. 1 which illustrates a double-ring finger ring embodying the principle of the invention, the ring 1 comprises a circular inner ring 2 and a circular outer ring 3, with the outer ring 3 being held in suspension externally of the inner ring 2. As mentioned above, the finger ring of this invention is useful not only as an accessory but also as a toy. Thus, both the inner ring 2 and outer ring 3 of the finger ring for ornamental use can be made of noble metal such as gold, silver, or platinum, while the inner ring 2 and outer ring 3 of the finger ring for use as a toy can be made of an inexpensive metal or synthetic resin material.
As shown in FIGS. 2 and 3, the circular inner ring 2 comprises an inner ring body 4 and four permanent magnets 5 each embedded in the outer circumferential region of the inner ring body 4. The inner ring body 4 is formed with four circular grooves 4a at circumferentially equal pitches. The four magnets 5 are cylindrical elements conforming to said circular grooves 4a and, after insertion into the grooves, are locked in position with an adhesive. The magnets 5 should be uniform in orientation with respect to polarity and, in the illustrated finger ring, the outer circumferential part of each magnet which faces the outer ring 3 constitutes an N-pole while the inner circumferential part constitutes an S-pole.
As shown detailedly in FIG. 2, the inner ring body 4 is generally configur
