Abstract

A barrier structure includes a continuous piece of elongated metal tape. The metal tape includes barbs spaced along an elongate body. Each of the barbs is connected securely to a barb root, and each barb root is connected securely to the elongate body. A first region of the elongate body is adjacent to each barb root, and a second region of the elongate body is adjacent to each first region distal from the barb root. A third region of the elongate body adjacent to each second region distal from the first region extends lengthwise from each second region and meets a corresponding third region that is extending lengthwise away from another second region. Each second region extends transversely and inwardly from the adjacent first region and the adjacent third region.

Claims

1. A barrier structure comprising a continuous piece of elongated metal tape, said metal tape comprising:

an elongate body defining a longitudinally extending channel and an elongate flange extending transversely from each side of said channel;

barb roots spaced along said tape and secured to said flanges;

a pair of tapered barbs secured to a barb root, said pair of tapered barbs extending in opposing longitudinal directions, and each of said tapered barbs forming a barb point;

a first region of said elongate body adjacent to the barb root;

a second region of said elongate body adjacent to the first region distal from the adjacent barb root;

a third region of said elongate body adjacent to the second region distal from said first region, the third region extending lengthwise from the second region and meeting a corresponding third region extending lengthwise away from another second region;

wherein the second region extends transversely and inwardly from said first region to the third region;

wherein a width of the flanges in the first region is greater than a width of the flanges in the second region, and wherein a width of the flanges in the third region is greater than the width of the flanges in the second region; and

wherein a width of the flanges in the first region is equal to the width of the flanges in the third region.

3. The structure of claim 1, wherein the flanges extend along the first region, the second region and the third region.

4. The structure of claim 1, wherein the first region extends away from said barb root a distance of approximately 0.25 inch.

6. The structure of claim 1, wherein said channel receives a reinforcing wire, said reinforcing wire being held in place by pressure exerted by walls of said channel.

7. The structure of claim 6, wherein said channel describes an arc extending between the flanges, the arc extending about 220°

.

8. The structure of claim 1, wherein each pair of barbs is part of a cluster of four barbs, each cluster of four barbs comprising a pair of barbs extending from each of said flanges.

9. The structure of claim 1, wherein the tape substantially forms a helix.

2. A barrier structure comprising a continuous piece of elongated metal tape, said metal tape comprising:

an elongate body defining a longitudinally extending channel and an elongate flange extending transversely from each side of said channel;

barb roots spaced along said tape and secured to said flanges;

a pair of tapered barbs secured to a barb root, said pair of tapered barbs extending in opposing longitudinal directions, and each of said tapered barbs forming a barb point;

a first region of said elongate body adjacent to the barb root;

a second region of said elongate body adjacent to the first region distal from the adjacent barb root;

a third region of said elongate body adjacent to the second region distal from said first region, the third region extending lengthwise from the second region and meeting a corresponding third region extending lengthwise away from another second region;

wherein the second region extends transversely and inwardly from said first region to the third region; and

wherein the width of the flanges in the first region is greater than the width of the flanges in each third region.

5. A barrier structure comprising a continuous piece of elongated metal tape, said metal tape comprising:

an elongate body defining a longitudinally extending channel and an elongate flange extending transversely from each side of said channel;

barb roots spaced along said tape and secured to said flanges;

a pair of tapered barbs secured to a barb root, said pair of tapered barbs extending in opposing longitudinal directions, and each of said tapered barbs forming a barb point;

a first region of said elongate body adjacent to the barb root;

a second region of said elongate body adjacent to the first region distal from the adjacent barb root;

a third region of said elongate body adjacent to the second region distal from said first region, the third region extending lengthwise from the second region and meeting a corresponding third region extending lengthwise away from another second region;

wherein the second region extends transversely and inwardly from said first region to the third region; and

wherein the second region comprises an arcuate cutout.

10. A barrier structure comprising a continuous piece of elongated metal tape, said metal tape comprising:

an elongate body defining a longitudinally extending channel and an elongate flange extending transversely from each side of said channel;

barb roots spaced along said tape and secured to said flanges;

a pair of tapered barbs secured to a barb root, said pair of tapered barbs extending in opposing longitudinal directions, said tapered barbs forming a barb point;

a first region of said elongate body adjacent to the barb root;

a second region of said elongate body adjacent to the first region distal from the adjacent barb root;

a third region of said elongate body adjacent to the second region distal from said first region, the third region extending lengthwise from the second region and meeting a corresponding third region extending lengthwise away from another second region;

wherein the second region extends transversely and inwardly from said first region to said third region;

wherein the tapered barb pair is part of a cluster of four barbs, each cluster of four barbs comprising a pair of tapered barbs extending from each of said flanges;

wherein the tape substantially forms a helix; and

wherein a width of the flanges in the first region is greater than a width of the flanges in the second region, and wherein a width of each of the flanges in the third region is greater than a width of the flanges in the second region.

11. The structure of claim 10, wherein said channel receives a reinforcing wire, wherein said channel describes an arc extending between the flanges, the arc extending about 220°

, and wherein said reinforcing wire is held in place by pressure exerted by walls of said channel.

12. The structure of claim 10, wherein said width of the flanges in the first region is equal to said width of the flanges in the third region.

13. The structure of claim 10, wherein a width of the flanges in the first region is greater than a width of the flanges in the third region.

14. The structure of claim 10, wherein the flanges extend along the first region, second region, and third region.
