Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
An electrical services pole which is height adjustable for clamping between the floor and the ceiling of a room, comprising: an upper generally tubular core section; a lower generally tubular core section slidingly receiving said upper tubular section through an upper end and forming therewith vertical conduit means for cables; means for controllably and positively affixing said upper and lower tubular core sections with respect to each other to obtain a selected overall affixed length thereof; and a lighting bowl carrying a light source and a light reflector, mounted fixedly on and supported by the lower core section at said upper end thereof, the upper core section extending through the lighting bowl.
Claim 2
Dependent Claim
112 words
An electrical services pole which is height adjustable for clamping between the floor and the ceiling of a room, comprising: an upper generally tubular core section; a lower generally tubular core section slidingly receiving said upper tubular section through an upper end and forming therewith vertical conduit means for cables; means for controllably and positively affixing said upper and lower tubular core sections with respect to each other to obtain a selected overall affixed length thereof; and a lighting bowl carrying a light source and a light reflector, mounted fixedly on and supported by the lower core section at said upper end thereof, the upper core section extending through the lighting bowl.
Claim 3
Dependent Claim
17 words
A pole as claimed in claim 1, wherein: the lighting bowl is adapted to throw light upwardly.
Claim 4
Dependent Claim
