A metal tape barrier is constructed of straight sections of elongated tape having barbs formed at spaced intervals along the tape. The barrier has a triangular configuration in cross section with the sections of tape forming the legs of the triangle. Adjoining convolutions of the barrier are connected together at spaced points in such a manner that the tape sections assume accordian pleat-like configurations when the barrier is stretched lengthwise for installation. A second set of sections of tape may be added to the barrier and may have their ends connected to intermediate regions of the sections forming the legs of the triangle. This second set of tape sections are disposed to close off the inside of the main triangle of the barrier. Connections to end regions of the tape sections are made at the location of the barbs on the tape so that the barbs project beyond the connections. In one configuration the barrier has a cross section like an isosceles triangle.
A barrier stucture of triangular cross section comprising a plurality of generally straight sections of elonggated metal tape having barbs formed at spaced intervals along the tape, said tape sections being connected to one another generally at their ends with each tape section constituting a leg of the triangular cross section, and means connecting a region of each said tape section intermediate its ends to an adjacent tape section intermediate its ends whereby the tape sections assume an accordian pleat-like configuration when the barrier structure is elongated.
A barrier structure comprising a plurality of generally straight sections of elongated metal tape having barbs formed at spaced intervals along the tape, said sections being connected one to the other at their ends and forming a helix of triangular cross section with each tape section constituting a leg of the triangular cross section.
A barrier structure comprising a plurality of triangular convolutions disposed in face to face relationship, each triangular convolution being formed of generally straight sections of elongated metal tape having barbs formed at spaced intervals along the tape, said tape sections being connected at their ends to form a base leg and two side legs of each convolution, and means connecting spaced apart regions of each leg of each convolution to a like leg of an adjoining convolution whereby the legs of the convolutions assume an accordian pleat-like configuration when the convolutions are separated to elongate and deploy the barrier.
