Abstract

A jewelry wristband is characterized by a flexible section adapted to conform to the wrist of the wearer with spring clips at each end to permit positive but releasable connection of jewelry or watch tips which are adapted to be placed at opposite ends of the watch. In addition, an intermediate expander section comprising arcuate plates hinged together is interposed in the flexible section to facilitate adjustment of the length of the flexible section to conform to the size of the wrist. The spring closure at each end of the flexible sections has a closed end of arcuate configuration and broad flat, generally rectangular leaf spring portions which diverge away from the connecting ends of the flexible section within the closed end, one spring portion being biased into a closed position within the return portion of the closed end so as to securely retain the ends of a watch tip or the like in place.

Dependent claims

In a wristband having a relatively thin, flat flexible section adapted to conform to a wearer's wrist and provided with a connecting pin at one end of said section, at least the one end thereof adapted for releasable connection of an end connecting bar on a jewelry tip and the like, the improvement comprising:

a unitary end retainer having one side pivotally connected to said connecting pin secured to the one end of said flexible section and an opposite side defining a curved return portion terminating in a free end spaced from the one side to form an entrance for insertion of an end connecting bar, and
a spring closure positioned within the end retainer and said spring closure including a closed connecting end of generally circular configuration pivotally connected to said connecting pin at the one end of said flexible section whereby said spring closure and said end retainer have a common pivotal connection and are pivotal in unison about said connecting pin, and flat leaf spring portions forming divergent continuations of said connecting end, one spring portion being of a length to extend between opposite sides of said end retainer, said one spring portion having its outermost edge of divergent extension biased against the inner surface of said free end and the other spring portion biased to incline in a direction away from said one spring portion toward the one side of said end retainer when said one spring portion is depressed whereby the end connecting bar may be forced past the outermost edge of said one spring portion for disposition within the curved return portion of the end retainer.
