Telephone handset assembly having rigid fastener for connecting handset assembly portion-portions theretogether

摘要

A fastener for a housing assembly. The fastener is comprised of a key having a hooked end portion formed to project beneath a front housing assembly portion, and a track member formed in a side wall of a rear housing assembly portion. Top and bottom face surfaces of the hooked projecting portion of the key, and top and bottom ledge surfaces of the track member are semi-circular in configuration. Interfitting surfaces of the front and rear housing assembly portions are also semi-circular in configuration. When the front and rear housing assembly portions are tandemly-positioned, and aligned with one another, the hooked end portion of the key and the track member engage with one another. Radial translation of the front housing assembly portion repositions the key projecting therebeneath at a fastening side of the track number to fasten thereby the front and rear housing assembly portions theretogether.
