Barbed tape product with a predetermined pattern of attachment points and attachment elements
View Patent ↗A barbed tape product as adjacent pairs of loops in which the loops of a pair are attached to each other at an attachment point that is circumferentially offset relative to an attachment point of the adjacent pair of loops. Additional attachment points may be provided in helically progressive positions between the first and second attachment points. The attachment points are positioned on one pair of loops so that each of the attachment points are circumferentially offset relative to all other attachment points on an adjacent pair of loops. The attachment points may be positioned in a predetermined helically progressive pattern on a coil of the product. The pattern may provide a predetermined natural configuration of the product when the product is in a deployed state of use. Attachment elements for attaching strands of the product together are sized and configured for strength and accuracy in automatically attached concertina or other barbed tape products.
1. A barbed tape concertina product comprising:
a strand of the product in the form of a continuous helical coil including at least a first pair of loops and a second pair of loops, said first and second pair of loops arranged in a continuous manner along a longitudinal axis of said helical coil;
a first attachment element at a first attachment point of the first pair of loops and holding the first pair of loops together;
a second attachment clement at a first attachment point of the second pair of loops and holding the second pair of loops together; and
a plurality of additional attachment elements at respective additional attachment points in helically progressive position on the strand between the first and second attachment elements, the plurality of additional attachment elements;
wherein the first attachment element is circumferentially offset relative to the second attachment element and wherein the first and second pairs of loops are adjacent pairs of loops.
2. The product of claim 1 , wherein the continuous coil further comprises:
additional pairs of loops and additional attachment elements holding the loops of each pair together and holding the pairs of loops together;
the attachment elements generally positioned on one pair of loops so that each attachment element is circumferentially offset relative to all other attachment elements on an adjacent pair of loops.
3. The product of claim 2 , wherein the attachment elements are positioned in a predetermined pattern on the continuous coil.
4. The product of claim 3 , wherein the pattern is a repeating pattern.
5. The product of claim 3 , wherein the pattern provides a predetermined natural configuration of the product when the product is stretched out in a deployed state of use.
6. A barbed tape product, comprising:
a strand of the product in the form of a continuous helical coil:
a first attachment configuration comprising a plurality of first attachment points wherein at least one first attachment point is on the strand;
a second attachment configuration comprising a plurality of second attachment points wherein at least one second attachment point is on the strand;
a plurality of first attachments at the plurality of first attachment points; and a plurality of second attachments at the plurality of second attachment points; the plurality of first and second attachments connecting respective adjacent loops to form pairs of loops;
wherein the first and second configurations correspond to respective first and second lengths of the strand that each extend through an are of at least about 360 degrees and
wherein each of the plurality of first attachment points are circumferentially offset relative to each of the plurality of second attachment points.
7. The barbed tape product of claim 6 , further comprising:
a first attachment at the at least one first attachment point;
a second attachment at the at least one second attachment point;
wherein the first and second attachments attach the first length to the second length of the strand and the first and second lengths form adjacent first and second loops of the strand corresponding to respective first and second adjacent cycles.
8. The barbed tape product of claim 6 , wherein the plurality of first attachments and the plurality of second attachments attach first and second pairs of loops comprising adjacent lengths of the strand together, wherein the first and second pairs of loops correspond to respective first and second adjacent cycles in a helically progressive pattern forming a barbed tape concertina product.
9. The barbed tape product of claim 6 , wherein the plurality of first attachments and the plurality of second attachments attach first and second adjacent lengths comprising adjacent first and second loops of the strand together, wherein the first and second lengths correspond to respective first and second adjacent cycles in a helically progressive pattern forming a barbed tape product.
