Abstract

See full text

A flashlight has a casing extending along an axis and adapted to hold an electric power supply, a light source fixed at a front end of the casing and electrically energizable to emit an axially forwardly directed light beam, an annular head fitted to the casing and axially shiftable thereon. Stops engaged between the head and the casing limit axial travel of the head relative to the casing. A lens is fixed in the head so that the lens and head can be shifted to focus the light beam. Thus the lamp head is captively attached to the casing. This creates an extremely compact structure that can be assembled quickly, thereby allowing manufacturing costs to be reduced. In addition, damaged components can be replaced quickly and easily.
