Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
285 words
A floor lamp comprising; an elongated base; and a U-shaped stanchion tube having an extended foot portion adapted to rest on the floor and secured at its end to substantially the center of an elongated side of said base at an angle normal thereto, an upright portion with a swivel formed therein, and a head portion extending at substantially a right angle to the upright portion and substantially parallel to said foot portion, said head portion having a lamp socket mounted at the end thereof; wherein said tube is formed of two members, a first member including said foot portion and a second member including said head portion, which members each include part of said upright portion and are connected at said swivel in a manner to form a flush mounted joint; wherein said first member includes a tubular section having the same outer diameter as said first member but having a smaller inner diameter and having a flat end surface the end of said tubular section opposite to said flat surface being flush mounted and secured to the upright portion end of said first member; a sleeve having an inner diameter which is the same as the inner diameter of said tubular section flush mounted inside the upright portion of said second member at its end to reduce the inner diameter of said member, said upright portion end with said sleeve therein having a flat end surface; and a tubular member dimensioned to fit and being snugly fitted in said tubular section and said sleeve and extending on both sides of said swivel; said flat end surfaces of said tubular section and said second member abutting to form the swivel surfaces of said swivel.
Claim 2
Dependent Claim
285 words
A floor lamp comprising; an elongated base; and a U-shaped stanchion tube having an extended foot portion adapted to rest on the floor and secured at its end to substantially the center of an elongated side of said base at an angle normal thereto, an upright portion with a swivel formed therein, and a head portion extending at substantially a right angle to the upright portion and substantially parallel to said foot portion, said head portion having a lamp socket mounted at the end thereof; wherein said tube is formed of two members, a first member including said foot portion and a second member including said head portion, which members each include part of said upright portion and are connected at said swivel in a manner to form a flush mounted joint; wherein said first member includes a tubular section having the same outer diameter as said first member but having a smaller inner diameter and having a flat end surface the end of said tubular section opposite to said flat surface being flush mounted and secured to the upright portion end of said first member; a sleeve having an inner diameter which is the same as the inner diameter of said tubular section flush mounted inside the upright portion of said second member at its end to reduce the inner diameter of said member, said upright portion end with said sleeve therein having a flat end surface; and a tubular member dimensioned to fit and being snugly fitted in said tubular section and said sleeve and extending on both sides of said swivel; said flat end surfaces of said tubular section and said second member abutting to form the swivel surfaces of said swivel.
Claim 3
Dependent Claim
56 words
A lamp as claimed in claim 1 including a protrusion formed as an integral part of said tubular member; and a stop means formed on an inside wall of said tubular section and adapted to interact with said protrusion to permit an almost 360° swivel action of said second member with respect to said first member.
Claim 4
Dependent Claim
294 words
A floor lamp comprising: an elongated base; a first stanchion tube having an extended foot portion adapted to rest on the floor and secured at its end to substantially the center of an elongated side of said base at an angle normal thereto, a right angle knee, and a vertical portion extending upward; a second stanchion tube having an extended substantially horizontal head portion having a lamp socket mounted at the end thereof, a right angle knee, and a vertical portion extending downward, said first and second stanchion tubes having substantially the same outer diameters; means for joining the ends of the vertical portions of said first and second stanchion tubes in a flush mounted joint which permits said second stanchion tube to be swiveled almost 360° with respect to said first stanchion tube; wherein said first stanchion tube includes a tubular section having the same outer diameter as said first stanchion tube but having a smaller inner diameter and having a flat end surface, the end of said tubular section opposite to said flat surface being flush mounted and secured to the vertical portion end of said first stanchion tube; a sleeve having an inner diameter which is the same as the inner diameter of said tubular section flush mounted inside the end of the vertical portion of said second stanchion tube to reduce the inner diameter of said second stanchion tube, said vertical portion and end with said sleeve therein having a flat end surface; and a tubular member dimensioned to fit and being snugly fitted in said tubular section and said sleeve and extending on both sides of said swivel; said flat end surfaces of said tubular section and said second part abutting to form the swivel surfaces of said swivel.
Claim 5
Dependent Claim
294 words
A floor lamp comprising: an elongated base; a first stanchion tube having an extended foot portion adapted to rest on the floor and secured at its end to substantially the center of an elongated side of said base at an angle normal thereto, a right angle knee, and a vertical portion extending upward; a second stanchion tube having an extended substantially horizontal head portion having a lamp socket mounted at the end thereof, a right angle knee, and a vertical portion extending downward, said first and second stanchion tubes having substantially the same outer diameters; means for joining the ends of the vertical portions of said first and second stanchion tubes in a flush mounted joint which permits said second stanchion tube to be swiveled almost 360° with respect to said first stanchion tube; wherein said first stanchion tube includes a tubular section having the same outer diameter as said first stanchion tube but having a smaller inner diameter and having a flat end surface, the end of said tubular section opposite to said flat surface being flush mounted and secured to the vertical portion end of said first stanchion tube; a sleeve having an inner diameter which is the same as the inner diameter of said tubular section flush mounted inside the end of the vertical portion of said second stanchion tube to reduce the inner diameter of said second stanchion tube, said vertical portion and end with said sleeve therein having a flat end surface; and a tubular member dimensioned to fit and being snugly fitted in said tubular section and said sleeve and extending on both sides of said swivel; said flat end surfaces of said tubular section and said second part abutting to form the swivel surfaces of said swivel.
Claim 6
Dependent Claim
