Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
219 words
A rectangular frame for displaying a sheet of informational material on an outer surface of a refrigerator or other steel surface: said frame being comprised of four tubes extending right angularly from one another in planar alignment; the ends of each tube being cut on the bias at a forty five degree angle to form miter joints at the frame corners; full length slots in the inner facing surfaces of the tubes for accommodating edge areas of a sheet of material; an elongated slot (32) in the outer surface of one of the tubes permitting insertion of a sheet into the frame; L-shaped tube connectors (22) inserted into the ends of the meeting tubes at the four miter joints; each tube connector having two legs (24 and 26) extending at right angles to each other, and a slot (27) extending completely through one leg and partway through the other leg; the slots in the L-shaped connectors being aligned with the slots in the inner facing surfaces of the tubes and said elongated slot in the outer surface of one of the tubes so that when a sheet of material is inserted through the elongated slot edge areas of the sheet will extend through the slots in the facing surfaces of the tubes into the slots in the L-shaped connectors.
Claim 2
Dependent Claim

A rectangular frame for displaying a sheet of informational material on an outer surface of a refrigerator or other steel surface: said frame being comprised of four tubes extending right angularly from one another in planar alignment; the ends of each tube being cut on the bias at a forty five degree angle to form miter joints at the frame corners; full length slots in the inner facing surfaces of the tubes for accommodating edge areas of a sheet of material; an elongated slot (32) in the outer surface of one of the tubes permitting insertion of a sheet into the frame; L-shaped tube connectors (22) inserted into the ends of the meeting tubes at the four miter joints; each tube connector having two legs (24 and 26) extending at right angles to each other, and a slot (27) extending completely through one leg and partway through the other leg; the slots in the L-shaped connectors being aligned with the slots in the inner facing surfaces of the tubes and said elongated slot in the outer surface of one of the tubes so that when a sheet of material is inserted through the elongated slot edge areas of the sheet will extend through the slots in the facing surfaces of the tubes into the slots in the L-shaped connectors.
Claim 3
Dependent Claim
20 words
The frame of claim 1 wherein each tube and each leg of each corner connector has a circular cross section.
Claim 4
Dependent Claim
34 words
