Abstract: A clasp mechanism that incorporates an extensible feature for ease of use is provided, which can be used on jewelry and other items. Instead of completely separating the ends of the attached jewelry or other item and then having to reconnect a clasp, the clasp mechanism separates and spreads apart by an interconnected extensible segment. The clasp can be attached to opposing ends of nearly any jewelry item, such as a bracelet, by known techniques such as soldering or bonding. The clasp incorporates an extensible segment such that when connected to opposing ends of a bracelet for example, the bracelet expands at the clasp mechanism to fit over a hand or foot and then contracts to securely fit at the wrist or ankle. The clasp mechanism does not require disconnecting and reconnecting when placing the jewelry piece onto one's person.

Abstract: A clasp for a wrist bracelet comprises upper and lower pivotally interconnected plates. Flanges are provided for connecting the upper plate to one end of a wrist bracelet and the free end of the bracelet is selectively received between a pivotally mounted locking plate and the lower plate. The plates are movable between a spaced apart or open position wherein the free end of the bracelet may be slid freely beneath the locking plate, thereby allowing a wearer to obtain a comfortable fit, and a locked position wherein the plates are pressed together and the locking plate is actuated so as to restrain further movement of the free end of the bracelet.
Abstract: At one of the extremities of the bracelet, which is formed of two rows of rectangular side links (1,2) and of a middle row of rectangular wider links (3), is arranged an end piece (6) having the appearance of two side links and of a middle link.
