Abstract
A utility handlamp, comprising battery jar means having enclosure means detachably secured thereto, is disclosed. Optical control means including light transmitting means, having reflector means affixed thereto, is engaged in threaded, rotatable relationship with a tubular extension of the enclosure means. A light source in the enclosure means may be focused by rotation of the optical control means. Stop means are provided to limit the extent of rotation of the optical control means. The enclosure body is further provided with a resilient, depending clip element which cooperates with parts of the battery jar means and enclosure means for mounting the handlamp on a belt, pocket, etc. and for providing a plurality of stable positions of the handlamp such that the path of travel of an emitted light beam may be varied along desired directions of angularity. Charging means including a specially-formed charging interface component is disclosed, which cooperate with the clip element of the handlamp to insure maintained positive electrical connection between the battery means and the charging means.
