Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
A lamp housing structure comprising, in combination: a transparent base plate, two end caps, each of said caps comprising lower portions forming a transverse groove, said base plate having opposite ends that extend into the grooves of the respective end caps, said end caps extending upwardly from the portions thereof having the transverse grooves, said end caps being in opposed and aligned relation, and an elongated housing member extending between said end caps with its ends frictionally engaged with said caps, said end caps, housing member, and the portion of the transparent base member beneath the housing member being adapted to enclose a lamp and such lamp being adapted to direct its light downwardly through said mentioned portion of the base plate.
Claim 2
Dependent Claim
122 words
A lamp housing structure comprising, in combination: a transparent base plate, two end caps, each of said caps comprising lower portions forming a transverse groove, said base plate having opposite ends that extend into the grooves of the respective end caps, said end caps extending upwardly from the portions thereof having the transverse grooves, said end caps being in opposed and aligned relation, and an elongated housing member extending between said end caps with its ends frictionally engaged with said caps, said end caps, housing member, and the portion of the transparent base member beneath the housing member being adapted to enclose a lamp and such lamp being adapted to direct its light downwardly through said mentioned portion of the base plate.
Claim 3
Dependent Claim
73 words
A lamp housing structure according to claim 1 in which each cap, around its side and top peripheral edges, is provided with pairs of parallel flanges that define grooves into which the opposite ends of the lamp-housing member are frictionally engaged, the outer flange of each pair being narrower than the flange that is parallel with it to provide lead-in surfaces for guiding insertion of the ends of the housing into said grooves.
Claim 4
Dependent Claim
38 words
A lamp housing structure according to claim 1 in which the end caps are formed of non-metallic material and having grooves in the upwardly extending portions into which the opposite ends of the housing member are frictionally engaged.
Claim 5
Dependent Claim
74 words
A lamp housing structure according to claim 3 in which the housing member is formed of sheet metal bent to have a U-shaped cross-sectional form, and the grooves in the upwardly extending portions of the end caps being shaped to conform to the U-shape of the housing member, the open side of the U-shaped housing member facing the transparent base plate to pass the light of the lamp to and through the base plate.
