Abstract
Abstract A flashlight has a casing containing batteries and a head assembly mounted on the casing. The head assembly includes a swivel head arranged for rotational movement about a swivel axis which is disposed at an acute angle with respect to a longitudinal axis of the casing. The swivel head carries a bulb and is asymmetrical so that rotational movement of the swivel head causes the beam of light emitted by the bulb to be directed in different directions. In one embodiment of the flashlight, the bulb is moved to various angular positions relative to the casing as the swivel head is rotated. In another embodiment of the flashlight, the bulb remains in a fixed relationship with the casing but a reflector is moved to various angular positions when the swivel head is rotated. The flashight also includes a push button type of switch mechanism for illuminating and extinguishing the bulb.
