In particular, one of the problems in the prior art in which links are added to a necklace, is that the links may flip, with respect to adjoining links, producing an unattractive and uncomfortable structure and requiring the wearer to manipulate the necklace links and to fix the displacement of flipped links, in accordance with the teachings of this invention, a flip lock is provided to ensure that one link may not flip with respect to adjoining links.

The novel aspects of the present invention include the undulating silhouette of the links, the interconnection of the links so as to form a substantially rear flat plane for the necklace, the substantial locking of adjoining links to prevent flipping and the provision of intermediate links having both the gate and fold-over latch structures enabling its connection to adjoining links to accomplish the above purposes. Multiple intermediate links may be utilized.

It should be understood that the preferred embodiment was described to provide an illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiment and with various modifications as are suited to the particular use contemplated. Other mechanical structural approaches can be provided to provide both the gate and latching function, and the claims of this invention are intended to cover all such structural approaches as may be apparent to those skilled in the art. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly legally and equitably entitled.
