Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A coupling for an article of furniture having interconnected vertically and horizontally disposed lengths of tubing comprising (a) a plurality of T shaped couplings each having (b) a tubular sleeve including a through bore for the reception of a length of the tubing and (c) an integral substantially right angularly disposed sleeve portion for the reception in endwise engagement of a length of said tubing, and having (d) an end wall within the right angularly disposed sleeve portion closing off the inner end thereof, (e) a screw projecting through said end wall and the tubing extending through the tubular sleeve to secure the coupling to the tubing, and (f) a screw extending through the right angularly disposed sleeve portion of the coupling to engage the tubing therein to secure to the coupling the length of tubing extending thereinto in endwise engagement, and said screw having a head counter-sunk within the surface of said sleeve.
Claim 2
Dependent Claim
154 words
A coupling for an article of furniture having interconnected vertically and horizontally disposed lengths of tubing comprising (a) a plurality of T shaped couplings each having (b) a tubular sleeve including a through bore for the reception of a length of the tubing and (c) an integral substantially right angularly disposed sleeve portion for the reception in endwise engagement of a length of said tubing, and having (d) an end wall within the right angularly disposed sleeve portion closing off the inner end thereof, (e) a screw projecting through said end wall and the tubing extending through the tubular sleeve to secure the coupling to the tubing, and (f) a screw extending through the right angularly disposed sleeve portion of the coupling to engage the tubing therein to secure to the coupling the length of tubing extending thereinto in endwise engagement, and said screw having a head counter-sunk within the surface of said sleeve.
Claim 3
Dependent Claim
39 words
The invention defined in claim 1 wherein the screw extending through the right angularly disposed sleeve of the coupling to engage the tubing therein is in an area in which the user does not normally come in to contact.
Claim 4
Dependent Claim
53 words
The invention defined in claim 1 wherein (a) a contoured plug having an axially extending portion projects into the open end of the tubing projecting through the through bore of the coupling to close the end of the tubing, and having (b) an outer diameter aligned with the outer surface of the tubing.
