ABSTRACT:
A flash light is provided in which the rotary positioning mechanism that retains the lamp head holder to the hollow cylindrical handle at any of a variety of angular positions includes a curved stub tube extending from the sloping bottom wall of the lamp head holder. The stub tube has an internally threaded, straight top end and a straight bottom end. The bottom end extends from the top end at an angle and perpendicularly intersects the sloping bottom wall of the lamp head holder. A plurality of circular recesses are formed in the sloping top wall of the hollow cylindrical handle and radially spaced around the center of the sloping top wall. A spring is mounted within the top end of the curved stub tube. A first steel ball is mounted in the bottom end of the curved stub tube, and a second steel ball is mounted within the top end of the curved stub tube and disposed between the first steel ball and the spring. A hold down screw is threaded into the top end of the curved stub tube to hold the spring therein and to force the first steel ball into engagement with one of the circular recesses.
