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;

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

said channel does not receive a reinforcing wire.

2. The structure of claim 1, wherein each second region comprises an arcuate cutout.

3. The structure of claim 1, wherein:

the continuous piece of elongated metal tape has a plurality of first regions, a plurality of second regions, and a plurality of third regions; and

a distance between the barb points of said pair of barbs is the same as a distance between adjacent ones of said second regions of said tape.

4. 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 inwardly from the first region to the third region;

the width of the flanges in the first region is greater than the width of the flanges in each third region; and

said channel describes an arc extending between the flanges, the arc extending less or equal to approximately 180°

.

5. The structure of claim 4, wherein a width of each of the flanges in each first region is greater than a width of each of the flanges in each second region, and wherein a width of each of the flanges in each third region is greater than a width of each of the flanges in each second region.

6. The structure of claim 4, wherein a width of each of the flanges in each second region is equal to a width of each of the flanges in each third region.

7. The structure of claim 4, wherein:

the continuous piece of elongated metal tape has a plurality of first regions, a plurality of second regions, and a plurality of third regions; and

a distance between the barb points of said pair of barbs is approximately the same as the distance between adjacent ones of said second regions of said tape.
