Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
165 words
A decorative device comprising, a housing having a top and a bottom, a socket at the top of the housing having a side wall and a transparent base, a light source in the housing directed at the base of the socket, a spray of optic fibers having lower ends, said lower ends being gathered in a bunch and depending into said socket, a sleeve over said bunch, means spacing said sleeve from the base and side wall of said socket to form ventilation channels for air circulation, transparent shield means at the lower end of said bunch for shielding said optic fibers from heat generated by said light source, and vents in the bottom and top of the housing arranged to vent heat generated by the light source from the housing, at least one of said vents being in communication with said ventilation channels to provide flow-through ventilation whereby air flows between said vent and ventilation channels, passing through the interior of said housing therebetween.
Claim 2
Dependent Claim
165 words
A decorative device comprising, a housing having a top and a bottom, a socket at the top of the housing having a side wall and a transparent base, a light source in the housing directed at the base of the socket, a spray of optic fibers having lower ends, said lower ends being gathered in a bunch and depending into said socket, a sleeve over said bunch, means spacing said sleeve from the base and side wall of said socket to form ventilation channels for air circulation, transparent shield means at the lower end of said bunch for shielding said optic fibers from heat generated by said light source, and vents in the bottom and top of the housing arranged to vent heat generated by the light source from the housing, at least one of said vents being in communication with said ventilation channels to provide flow-through ventilation whereby air flows between said vent and ventilation channels, passing through the interior of said housing therebetween.
Claim 3
Dependent Claim
41 words
A decorative device according to claim 1 in which said light source comprises a reflector focusing at the lower end of said bunch and an electric light bulb surrounded by said reflector, said reflector having vent openings therethrough adjacent said bulb.
Claim 4
Dependent Claim
72 words
A decorative device according to claim 1 wherein said transparent shield means comprises a strip of flexible, light-transmissive, heat-reflecting material having ends fastened to the inside surfaces of the housing top and a midsection curving downwardly beneath said socket, said shield means having a transverse dimension less than the transverse dimension of said housing such that air may flow from one side of said shield to the other to allow flow-through ventilation.
Claim 5
Dependent Claim
28 words
A decorative device according to claim 1 wherein said transparent shield means comprise a layer of light-transmissive, heat-reflective material coating the surfaces of the base of said socket.
Claim 6
Dependent Claim
62 words
A device according to claim 1 in which the top of said housing is stepped thereby forming upper and lower steps with the top vents located between said upper and lower steps, the wall of the lower step extending inwardly beneath the upper step to serve as a light baffle spaced outwardly from said socket, said socket depending from the upper step.
Claim 7
Dependent Claim
59 words
A device according to claim 1 further including a plurality of spaced apart legs extending downwardly from the bottom of the housing outwardly of and adjacent the vents in said bottom, said legs resting on a horizontal surface such that said horizontal surface forms a light baffle whereby light passing through said vents is shielded by said horizontal surface.
Claim 8
Dependent Claim
32 words
A device according to claim 1 in which the bottom of the housing has a central downwardly dished portion in which said light source is mounted and which contains the bottom vents.
Claim 9
Dependent Claim
19 words
A decorative device according to claim 1 in which said transparent shield means comprises a film of polyethylene terephthalate.
Claim 10
Dependent Claim
148 words
A decorative device comprising, a housing having a bottom and a top with a housing aperture extending therethrough, a baffle plate spaced above the top of said housing and covering said housing aperture, said baffle plate having a hollow cylindrical holder extending through said housing aperature into said housing, said holder having an outer diameter less than the diameter of said housing aperature thereby forming a venting slot between said holder and the top of said housing, and electric light source in the housing directed at the holder, a spray of optic fibers having lower ends, said lower ends being gathered in a bunch within said holder, and a vent in the bottom of said housing to provide flowthrough ventilation whereby air flows into the vents in said bottom, through said housing, through said venting slot and out between said baffle plate and the top of said housing.
Claim 11
Dependent Claim
148 words
A decorative device comprising, a housing having a bottom and a top with a housing aperture extending therethrough, a baffle plate spaced above the top of said housing and covering said housing aperture, said baffle plate having a hollow cylindrical holder extending through said housing aperature into said housing, said holder having an outer diameter less than the diameter of said housing aperature thereby forming a venting slot between said holder and the top of said housing, and electric light source in the housing directed at the holder, a spray of optic fibers having lower ends, said lower ends being gathered in a bunch within said holder, and a vent in the bottom of said housing to provide flowthrough ventilation whereby air flows into the vents in said bottom, through said housing, through said venting slot and out between said baffle plate and the top of said housing.
