Abstract

Abstract A battery powered flashlight includes a housing defining an interior cavity which supports an internal battery power source and flashlight bulb in operative communication with a movable switch also supported upon the housing. The housing further defines an opening and a generally parabolic reflector communicating the output light of the flashlight bulb to the housing opening. A simulated toy figure is joined to and appears to extend from the upper portion of the housing and supports a miniature replica of the flashlight. A curved light transmissive light pipe is coupled between the miniature light replica and the flashlight bulb in an optical coupling which permits a portion of the flashlight bulb output energy to be coupled through the light pipe and directed outwardly from the miniature flashlight to produce a secondary light beam. Movable colored filters are supported within the housing to permit coloration of the light beams.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 111 words
A flashlight comprising: a housing having an interior cavity and first light output opening; a reflector supported within said housing having an open side directed toward said first output opening; a light bulb supported within said reflector; a battery power source operatively coupled to said light bulb for causing it to emit light; a figure extending from said housing defining a second light output opening and an internal passage between said second light output opening and said interior cavity; and passive light coupling means for receiving a portion of the light produced by said light bulb and coupling it to said second light output opening to produce a secondary light beam.
Claim 2
Dependent Claim 111 words
A flashlight comprising: a housing having an interior cavity and first light output opening; a reflector supported within said housing having an open side directed toward said first output opening; a light bulb supported within said reflector; a battery power source operatively coupled to said light bulb for causing it to emit light; a figure extending from said housing defining a second light output opening and an internal passage between said second light output opening and said interior cavity; and passive light coupling means for receiving a portion of the light produced by said light bulb and coupling it to said second light output opening to produce a secondary light beam.
Claim 3
Dependent Claim 22 words
