ABSTRACT:
A pop-up handle assembly having a base with a mounting panel and a tubular housing and a handle with a tubular stem axially movable within a hollow sleeve rotatable within the tubular housing. The handle mounts a key-plug which is depressable to release a lock pin carried by the tubular stem from engagement with a shoulder in the tubular housing whereby the handle pops-up to an operative position under the urging of a spring. The key-plug is rotatable between locked and unlocked positions and into an unlocked position can be depressed to release the handle for movement without the use of a key. The handle assembly has provision for pop-up of the handle from the inner side thereof to free the handle for rotation regardless of whether the key-plug is either locked or unlocked.
