Abstract

A portable telephone handset construction is provided having a chassis to which is slidably assembled an end closure which is collapsible to a position for protecting a selected portion of said chassis from contact and impact by other objects and to minimize its contamination by dust and other debris. When fully extended the end closure may represent an earpiece or mouthpiece of the handset construction which is capable of angular orientation relative to the chassis so as to assume the normal configuration of the earpiece or mouthpiece of a conventional telephone handset. The end closures are guided during sliding movement relative to the chassis by means of cooperating guide tracks and guide elements. The end closures containing the earpiece and mouthpiece are articulated relative to the chassis by spring members and interrelating mechanical structure.
