ABSTRACT:
The invention provides an improved connector pin for use in connecting adjacent links of a bracelet, particularly a link watch band, together in releasable yet secure fashion so that one or more links can be readily removed with a simple cylindrical tool to adjust the length of the bracelet to the wrist size of the wearer. The connector pin is typically received in a transverse passage defined by coaxially aligned bores extending through adjacent links of the bracelet and includes an intermediate shaft adapted to be disposed in the transverse passage defined by the bores to provide an axis for relative rotation between adjacent links, thereby imparting flexibility to the bracelet so that it conforms to the wrist shape of the wearer, and an enlarged retaining head at opposite ends of the intermediate shaft with each retaining head being bifurcated so as to be compressible in size to enable removal of the connector pin simply by pushing one of the retaining heads through the transverse passage and out the outer side.
In a particularly preferred embodiment, the bores defining the transverse passage through adjacent links include enlarged end chambers which receive and conceal the enlarged, bifurcated retaining heads of the connector pin from view in a functionally and aesthetically advantageous manner.
