Abstract

A hingeless temple for eyewear comprises a unitary length of flexible material such as a shape-memory metal or metal alloy which has an elongated section,a forward section and a flexible pivot section. The pivot section is characterized by three bends which form a generally serpentine configuration. In the unbiased position, the temple extends in the open position with respect to the eyewear front. Means are provided for selectively and releasably closing the temple in the folded position with respect to the eyewear front. When the closing means are released, the temple automatically pivots to the open position. The front end of the temple may be attached directly to the eyewear front, thereby negating the need for a separate hinge assembly.
