Abstract: Disclosed herein is a polyolefin splittable conjugate fiber comprising at least two components of polyolefin resins (including polystyrene resins) and having a cross sectional structure with each of the components arranged alternately, wherein at least one of the component resins contains 1-30% by weight of an ethylene-vinyl alcohol copolymer whose saponification degree is 95% or more. Using the splittable conjugate fiber of the invention, a fiber structure having a fine and even surface can be provided.

Abstract: Disclosed is a collapsible glasses frame having fronts which are spread when used and collapsible when not used, comprising a mechanism for setting a pad member into a predetermined position when the fronts are spread for use, and a mechanism for shifting the pad member when said fronts are folded up, thus enabling the glasses frame to be made more compact.

Abstract: A spectacle frame comprises a pair of plastic rim members suitable for containing individual lenses therein and formed in an open ring-like shape, each of the rim members having at the ends of the open ring thereof a pair of coupling portions in which the rim members are closed by the coupling portions being coupled to each other, a pair of temple members, and fastening means provided to fasten the coupling portions to each of the rim members. The fastening means includes a metal member having one end provided with an internal thread and the other end provided with a hinge piece coupled to one of the pair of temple members, a portion of the metal member including the one end being embedded in one of the coupling portions, and a male screw threadably engaged with the internal thread through the other of the coupling portions.
