Abstract
A barrier which is extensibly deployed from a vehicle and which includes at least three coils of barbed tape supported and spaced from one another with an upper coil located above two lower coils. The coils are spaced parallel from one another, and are supported, by transverse rods located along the respective lengths of the coils. Each coil is a plurality of short coils which are interconnected in axial alignment in head-to-tail relation, with adjacent short coils having oppositely directed senses of rotation to counterbalance any net rotational forces produced by each short coil.

A barrier which includes at least two adjacent compressed coils of suitable material which are axially extensible so that the axial directions of the coils extend in a spaced parallel direction to one another, and a plurality of support devices which provide connection between the coils at a plurality of locations along their respective lengths and space the coils outside of one another thereby to prevent entanglement between coils, each coil comprising a plurality of short coils which are interconnected in axial alignment in head-to-tail relation with adjacent short coils having oppositely directed senses of rotation so that any net rotational forces produced by each short coil are counterbalanced.
The combination of a barrier and a vehicle,
- said barrier including at least two adjacent compressed coils of suitable material which are axially extensible so that the axial directions of the coils extend in a spaced parallel direction to one another, and a plurality of support devices which provide connection between the coils at a plurality of locations along their respective lengths and space the coils outside of one another thereby to prevent entanglement between coils, each coil comprising a plurality of short coils which are interconnected in axial alignment in head-to-tail relation with adjacent short coils having oppositely directed senses of rotation so that any net rotational forces produced by each short coil are counterbalanced, one of said coils being an uppermost coil,
- said vehicle including elongate means supporting said uppermost coil of said barrier.
