Abstract
Abstract A clip for joining crossed reinforcing bars while holding each of the bars independently of the other includes a formed body of resilient plastic material of general U-shape configuration including confronting flange portions carried by an intermediate web portion at one end of the flanges. The interior surfaces of the flanges are formed to include arcuately relieved portions for yieldingly receiving and gripping one bar lying therein in a plane disposed between the planes of each of the flanges. The flanges also include aligned openings formed therethrough for receiving another bar disposed crosswise of the first bar. The flanges include passages leading into the aligned openings to permit the second bar to be lodged in the aligned openings independently of the first bar. Inner circumferential portions of the aligned openings are formed to include a thin flexible lip extending radially into the aligned openings for accommodating variations in sizes of reinforcing bars and frusto-conically shaped recesses adjacent the aligned openings are formed in the outer surfaces of the flanges for readily receiving reinforcing bars therein.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A clip for use in joining a pair of substantially cylindrical reinforcing bars of a type used in reinforcing concrete comprising a substantially U-shaped molded unit having a flexible web portion forming a pressure transmitting panel, opposed flanges carried by said web portion to depend downwardly therefrom, said flanges being yieldingly separable to permit one of said bars to enter and lie in a plane therebetween, the confronting surfaces of said flanges including arcuately relieved portions for yieldingly receiving and gripping said one bar therein independently of the other bar, aligned openings formed through said flanges for receiving the other bar therein disposed crosswise of said one bar, said flanges including passages leading into said aligned openings to permit the other bar to be disposed in said aligned openings and seated therein independently of said one bar, and portions of a frustoconically shaped recess formed in said flanges in the region surrounding said aligned openings for readily receiving a reinforcing bar in said openings.
Claim 2
Dependent Claim
164 words
A clip for use in joining a pair of substantially cylindrical reinforcing bars of a type used in reinforcing concrete comprising a substantially U-shaped molded unit having a flexible web portion forming a pressure transmitting panel, opposed flanges carried by said web portion to depend downwardly therefrom, said flanges being yieldingly separable to permit one of said bars to enter and lie in a plane therebetween, the confronting surfaces of said flanges including arcuately relieved portions for yieldingly receiving and gripping said one bar therein independently of the other bar, aligned openings formed through said flanges for receiving the other bar therein disposed crosswise of said one bar, said flanges including passages leading into said aligned openings to permit the other bar to be disposed in said aligned openings and seated therein independently of said one bar, and portions of a frustoconically shaped recess formed in said flanges in the region surrounding said aligned openings for readily receiving a reinforcing bar in said openings.
Claim 3
Dependent Claim
172 words
A clip for use in joining a pair of substantially cylindrical reinforcing bars of a type used in reinforcing concrete comprising a substantially U-shaped molded unit having a flexible web portion forming a pressure transmitting panel, opposed flanges carried by said web portion to depend downwardly therefrom, said flanges being yieldingly separable to permit one of said bars to enter and lie in a plane therebetween, the confronting surfaces of said flanges including arcuately relieved portions for yieldingly receiving and gripping said one bar therein independently of the other bar, aligned openings formed through said flanges for receiving the other bar therein disposed crosswise of said one bar, said flanges including passages leading into said aligned openings to permit the other bar to be moved into said aligned openings and seated therein independently of said one bar, the radially inner edge of said aligned openings comprising a thin arcuate flexible lip portion extending radially into said aligned openings for accommodating variations in the sizes of reinforcing bars disposed in said aligned openings.
Claim 4
Dependent Claim
172 words
A clip for use in joining a pair of substantially cylindrical reinforcing bars of a type used in reinforcing concrete comprising a substantially U-shaped molded unit having a flexible web portion forming a pressure transmitting panel, opposed flanges carried by said web portion to depend downwardly therefrom, said flanges being yieldingly separable to permit one of said bars to enter and lie in a plane therebetween, the confronting surfaces of said flanges including arcuately relieved portions for yieldingly receiving and gripping said one bar therein independently of the other bar, aligned openings formed through said flanges for receiving the other bar therein disposed crosswise of said one bar, said flanges including passages leading into said aligned openings to permit the other bar to be moved into said aligned openings and seated therein independently of said one bar, the radially inner edge of said aligned openings comprising a thin arcuate flexible lip portion extending radially into said aligned openings for accommodating variations in the sizes of reinforcing bars disposed in said aligned openings.
Claim 5
Dependent Claim
143 words
In a clip for use in joining a pair of substantially cylindrical reinforcing bars of a type used in reinforcing concrete comprising a substantially U-shaped molded unit having a flexible web portion forming a pressure transmitting panel, opposed flanges carried by said web portion to depend downwardly therefrom in spaced apart relation to allow a substantial body of concrete to be deposited therebetween, aligned openings formed through said flanges, and sufficiently open passages leading into said openings to permit a reinforcing bar to be forced therealong to be disposed into said openings crosswise of another reinforcing bar lying between and in a plane parallel to said flanges, the radially inner edge of said aligned openings being defined by a thin arcuate flexible lip portion extending radially into said openings for accommodating variations in the sizes of reinforcing bars disposed within said aligned openings.
Claim 6
