ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a fastening device for appending a piece of jewelry to a jewelry clasp or the like, which has a connecting piece with a lug attached in the vicinity of a surface indentation for accommodating the end of a necklace or tie-on thread. Piece of jewelry is meant to include above all necklaces, necklace parts, but also pendants, and jewelry clasp or the like is meant to include not only a true clasp but also pins and brooches, intermediate pieces of a necklace or other decorative parts of a piece of jewelry.
DESCRIPTION OF THE PRIOR ART
For appending a piece of jewelry to a jewelry clasp or the like, known fastening devices require an additional connecting element, mostly a ring, which on the one hand engages in the piece of jewelry and on the other hand in the connecting piece of the jewelry clasp or the like, whereby not only the manufacture of these fastening devices becomes rather expensive, but the area where the piece of jewelry is appended quite conspicuously stands out against the remaining piece of jewelry due to the additional connecting element and impairs the esthetic appearance of this piece of jewelry.
SUMMARY OF THE INVENTION
It is therefore the object underlying the invention to create a fastening device as described above, which involves a safe and yet economic connection of piece of jewelry and jewelry clasp or the like, and without a disturbing influence on the total esthetic appearance of the jewelry leads to a smooth transition between the piece of jewelry and the jewelry clasp.
This object is solved by the invention in that of the lug which is open at a point of separation one end portion on the side of the point of separation is fixed at the connecting piece along the edge of the surface indentation, and the other end portion is bent up from the edge of the surface indentation, that upon introducing a necklace or tie-on thread forming a thickened end portion through the expanded point of separation, the bent-up end portion can be pressed down onto the edge of the surface indentation, and that the clear inner width of the lug is smaller than the clear inner width of the edge of the indentation and smaller than the outer width of the thickened end portion which can be pressed into the surface indentation.
Due to the open and drawn-up lug sufficient room is available for introducing the thickened end portion of a necklace or tie-on thread into the lug, whereupon the lug is closed by pressing down the bent-up end portion, and the thickened end portion is retained inside the surface indentation. Appending a piece of jewelry to a jewelry clasp or the like can therefore be performed quickly and easily and makes the use of an additional connecting element superfluous, where a neat and smooth attachment of the piece of jewelry to be appended to a jewelry clasp, an intermediate part or the like is achieved.
When appending a knotted pearl necklace to a jewelry clasp, the knot after the last pearl is advantageously provided itself as a thickened end portion of the necklace thread, so that the connecting piece can follow the last pearl without a major distance, and the jewelry clasp perfectly fits in the overall picture of the necklace.
When anchoring parts adhered or clamped to the thread end form the thickened end portion, the fastening device can optimally be adapted to the respective pieces of jewelry and always ensures a safe and easy-to-handle connection.
