ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a necklace, in particular, one wherein connecting metal fittings of the necklace to be positioned on the rear side of neck is prevented from appearing on the front side with turning around the neck.
DISCUSSION OF THE BACKGROUND
Generally, a necklace comprises unit: pieces (koma in Japanese) arranged successively to make a chain and connecting metal fittings attached at both ends thereof, and is a personal ornament, which is used by hanging around neck and by connecting the connecting metal fittings at both ends between themselves.
When wearing such necklace, in particular, with a necklace successively arranged a lot of similarly shaped pieces made from the same material, a necklace structured so that the portion of connecting metal fittings is relatively heavier than the portion of pieces, or the like, it often ended up to turn naturally around neck on wearing and the portion of connecting metal fittings come to move to the front side of neck, thus giving an unseemly impression as a personal ornament.
As a result of various investigations to solve such inconvenience, the invention provides a necklace that does not end up to turn around neck on wearing.
SUMMARY OF THE INVENTION
Namely, the invention provides a rotation-preventive necklace characterized in that, in the necklace successively arranged a plurality of pieces and provided with connecting metal fittings at both ends, at least one or more of pieces neighboring said connecting metal fittings are formed with hollow members and other pieces are formed with solid members. And, it is effective to form all pieces with the same material and in the same shape, or to use pieces having different shapes of plural types repeatedly in turn, respectively. Further, it is effective to form the respective pieces locating in the middle portion of necklace being less than approximately ⅓ of the overall length of necklace with solid members and the respective pieces locating in the portion of both ends of said necklace being less than approximately ⅓ of the overall length of necklace with hollow members. Moreover, it is also effective to use metal as a prime material of pieces.
Moreover, other rotation-preventive necklace of the invention is characterized in that, in the necklace successively arranged similarly shaped pieces and provided with connecting metal fittings at both ends, the weight of pieces neighboring connecting metal fittings is made lighter than the weight of pieces in the middle portion.
Moreover, other one of the invention is a rotation-preventive necklace characterized in that, in the necklace successively arranged a plurality of similarly shaped ring-like pieces by joining them each other and provided with connecting metal fittings at both ends, the pieces neighboring connecting metal fittings are formed with pipe material and the pieces in the middle portion are formed with solid material of the same material as that of said pipe material. At this time, it is effective to fill a substance lighter than said pipe material, for example, aluminum, wax or resin inside the pipe material in the case of pipe material being gold, silver, brass or the like that is the quality of material used commonly for the personal ornament.
Moreover, other one of the invention is a rotation-preventive necklace characterized in that, in the necklace successively arranged a plurality of similarly shaped ring-like pieces by joining them each other and provided with connecting metal fittings at both ends, the pieces neighboring connecting metal fittings are formed with a pipe material filled inside by a filler of light weight and the pieces in the middle portion are formed with the pipe material filled inside by a filler of heavy weight which is heavier than said filler of light weight. At this time, it is good to use heavy metal such as lead or copper as the filler of heavy weight in the case of the filler of light weight being light metal such as aluminum, wax or resin, but, in short, it is only necessary that weight of the filler in pieces of the middle portion is greater than weight of the filler in pieces neighboring connecting metal fittings.
Furthermore, other one of the invention is a rotation-preventive necklace characterized in that, in the necklace successively arranged a plurality of similarly shaped hollow pieces by joining them each other and provided with connecting metal fittings at both ends, the pieces in the middle portion is plated thereon more thickly than pieces neighboring connecting metal fittings.
