Changeable contour construction of wireless telephone
First Claim
1. A portable telephone handset comprising:
- (a) an elongate substantially straight telephone handset chassis having an end section;
(b) a pair of guide and positioning arms each having pivots connected in pivotal relation with said telephone chassis, each of said guide and positioning arms being flexible and having an elongate arm section and a locking projection thereon;
(c) at least one end closure defining internal guide slots of elongate configuration and having spaced locking recesses defined in part by a cam surface and being disposed for receiving a respective one of said locking projections, said end closure being in linear sliding and articulatable assembly with said telephone handset chassis and being movable easily from a collapsed position where said at least one end closure encloses said end section of said telephone handset chassis and being linearly movable to an extended position exposing said end section of said telephone handset chassis;
(d) said elongate arm section of each of said guide and positioning arms being received in guiding relation within a respective one of said internal guide slots; and
(e) said at least one end closure being linearly movable in guided relation with said telephone chassis and said guide and positioning arms from collapsed positions enclosing said end section of said telephone chassis and extended positions exposing said end section of said telephone chassis, said at least one end closure further being pivotally movable about said pivots at the substantially fully extended positions to thus provide for articulation of said at least one end closure to inclined relation with said telephone chassis.

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.
