摘要： An extensible clasp is described for use with a continuous flexible wristlet, as for a watch. The clasp comprises first and second elongated portions that are connected by a hinge pin. The first portion is slightly curved to conform to the shape of a wrist and is formed of two parts that can slide along each other, with one part carrying the hinge pin at one end and being formed with a single hole near its other end, and the other part being formed with several aligned holes arranged selectively to register with the single hole. The second portion is also curved, but slightly more so, and carries a beak element which, upon the two portions being folded over each other to close the clasp, is pushed through a registering pair of holes to lock the clasp in a selected position. To open the clasp, pressure is exerted in the region of the middle of the second portion and/or a flap, pivotally mounted on the second portion at its free end but restrained from pivoting backwards beyond a certain point, is pulled upwards to ease the beak element out of the registering holes by a camming action.

摘要： A bracelet comprises a plurality of interengaging pivotally-connected flat links. Each link has an elliptical contour and a central diamond-shaped opening, a first channel in the upper face and a second channel in the lower face, the channels crossing each other so that the sides of the channels coincide with the pairs of opposed edges of the opening. One end of the first channel has a slot extending from the edge to the opening for the passage of another link during assembly. This other link is turned through 90 DEG to lie in the same plane after passing through the slot and the links are pivotally connected by pivot pins which pass through apexes of the diamond-shaped opening lying on the center line of the bracelet and are received in holes extending within the thickness of the links.
