ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates generally to trouble lights and, more particularly, to trouble lights including reflectors. In the past, such reflectors were commonly fixed relative to the handle and, as a consequence, the direction of reflection was often determined by the manner in which the trouble light hook engaged the supporting member. Such direction of reflection was, accordingly, often in a direction which did not maximize the light available to the user at the spot where the user was working.
Attention is directed to the following U.S. Patents:
U.S. Pat. No. 4,086,482, Torgerson, issued Apr. 24, 1978
U.S. Pat. No. 4,236,195, Kovacik, issued Nov. 25, 1980

SUMMARY OF THE INVENTION
The invention provides a trouble light comprising a handle including a light bulb socket fixed in the handle and adapted to receive an electric light bulb, a cage mounted on the handle and adapted to enclose the light bulb, a reflector located within the cage, and means on the reflector and on one of the handle and the socket for mounting the reflector on the one of the handle and the socket for rotary movement relative to the handle.
The invention also provides a trouble light comprising a handle including an end portion, a light bulb socket located adjacent said end portion and adapted to receive an electric light bulb, and an electric switch operable to control energizing of said light bulb socket, a protective cage mounted on said end portion of said handle, adapted to enclose and protect the light bulb, and including openable structure for passing an electric bulb into said protective cage for threaded insertion into said light bulb socket, and a hook for suspending said trouble light from a support, a reflector located within said cage, and means on said reflector and on said end portion of said handle for mounting said reflector on said handle for rotary movement relative to said handle. The invention also provides a trouble light comprising a handle including an end portion, a light bulb socket located adjacent the end portion and adapted to receive an electric light bulb, and an electric switch operable to control energizing of the light bulb socket, a cage mounted on the end portion of the handle, adapted to enclose and protect the light bulb, and including an openable structure for passing an electric light bulb into the cage for threaded insertion into the light bulb socket, and a hook for suspending the trouble light from a support, an annular collar fixedly mounted on the cylindrical portion of the end portion of the handle and including two half-sections each including a partially cylindrical inner surface portion frictionally engaging the cylindrical portion of the end portion of the handle, an arcuate groove extending radially outwardly from the partially cylindrical inner surface portion, and a partially cylindrical outer surface portion spaced radially outwardly from the partially cylindrical inner surface portion and from the cylindrical portion of the handle to form an annular space between the handle and the partially cylindrical outer surface portions, and a reflector located within the cage and including an end portion comprising a cylindrical portion located in the annular space between the cylindrical portion of the handle and the partially cylindrical outer portions of the collar, and a flange extending radially outwardly from the cylindrical portion of the end portion of the reflector and located in the grooves of the half sections of the collar, and fasteners connecting together the half-sections and frictionally engaging the cylindrical inner surface portions of the half-sections of the collar against the cylindrical portion of the handle.
The invention also provides a trouble light comprising a handle including a pair of partial-sections, one of said partial-sections integrally including a first collar segment, and a second collar segment assembled to the one partial-section, a light bulb socket fixed in the handle and adapted to receive an electric light bulb, a cage mounted on the handle and adapted to enclose the light bulb, a reflector located within the cage, and means on the reflector and on the first and second collar segments for mounting the reflector on the handle for rotary movement relative to the handle.
The invention also provides a trouble light comprising a handle including a first half-section, a second half-section including a first collar segment, a second collar segment assembled to the first collar segment to form a collar, a light bulb socket located adjacent the collar and adapted to receive an electric light bulb, and an electric switch operable to control energizing of the light bulb socket, a protective cage mounted on the handle, adapted to enclose and protect the light bulb, and including openable structure for passing an electric bulb into the protective cage for threaded insertion into the light bulb socket, and a hook for suspending the trouble light from a support, a reflector located within the cage, and means on the reflector and on the collar for mounting the reflector on the handle for rotary movement relative to the handle.
