A continuous strip of coiled material is provided with protrusions, such as barbs, which are oriented to eliminate mutual interference when the coiled material is stacked in a compact, collapsed nested condition and wherein each turn of the coil is permanently fixed at equiangularly spaced multiple points alternately to its adjacent trailing and leading turns of the coil. An intrusion detection system signals intrusion into the space encompassed by the above mentioned coil and features a microwave energy source, receiver and detector for indicating a reduction in received microwave energy at the receiver indicative of intrusion into or other disruption of the energy guided path determined by the coil. Another embodiment of the barrier provides for similarly barbed strip material provided in a series of linear lengths with each length reversely folded at a succession of fold points to provide a sawtooth profile with the fold points permanently fixed alternately to corresponding fold points of adjacent trailing and leading strip lengths.
A barrier coil comprising a continuous strip of tape having a major surface with a face width dimension substantially greater than its thickness, the coil having multiple turns of substantially uniform diameter, the coil being extensible about its central axis from a retracted position to a deployed position, the coil in its retracted position having confronting major surfaces of ajdacent turns of the coil in collapsed nested face-to-face relation, the coil having turns rigidly and permanently fixed at circumferentially spaced multiple coil attachment points to adjacent trailing and leading turns of the coil, said coil attachment points continuously maintaining said confronting major surfaces of adjacent turns of the coil in abutting face-to-face surface contact engagement to prevent longitudinal or radial or pivotal movement of adjacent turns relative to one another at said coil attachment points, whereby the attachment points ensure return of the coil from deployed to retracted positions with the confronting major surfaces of adjacent turns of the coil in said collapsed nested face-to-face relation.
A barrier comprising a body formed of strip material having opposite first and second ends, the opposite first and second ends being interconnected by a body portion therebetween formed of a plurality of intermediate strips, the strip material being formed of substantially planar metal strip stock including barb clusters spaced apart along the length of the strip material, the intermediate strips each comprising a linear length of material having equally spaced apart fold points, each strip length being reversely folded at successive fold points and providing a sawtooth profile, each intermediate strip being rigidly and permanently fixed at spaced attachment points in alternate succession to adjacent trailing and adjacent leading strips of the barrier, the intermediate strips thereby being secured to prevent longitudinal movement relative to the adjacent strips at said attachment points, the barrier being extensible from a retracted position, wherein adjacent strips are in collapsed nested relation to one another, to a deployed position with adjacent strips of the barrier being in extended relation to one another between the attachment points.
A barrier coil extensible and retractable about its central axis and comprising a continuous strip of coiled material, the coil having opposite terminal end turns and a plurality of closed intermediate turns of substantially uniform size, each intermediate turn of the coil being permanently fixed at a first point to an adjacent trailing turn of the coil and at a second point to an adjacent leading turn of the coil, and a coil turn spacer assembly extending longitudinally of the coil in parallel relation to its axis and being secured at interconnecting corresponding points of the coil turns, the spacer asembly having substantially equal lengths between secured interconnecting points of the coil turns with such lengths each being relatively stiff and flexible but movable into a folded position within the coil upon coil collapse, the lengths of the spacer assembly being formed of a material providing a memory set in folded position for repeated retraction into an interference-free folded position upon coil collapse.
A barrier coil extensible and retractable about its central axis and comprising a continuous strip of coiled metal material, the coil having opposite terminal end turns and a plurality of closed intermediate turns of substantially uniform size, each intermediate turn of the coil being permanently fixed at a first point to an adjacent trailing turn of the coil and at a second point to an adjacent leading turn of the coil, and an intrusion detection system for signaling intrusion into the space encompassed by said coil as well as physical disruption of the continuity of said coil including a microwave energy source for directing said energy along the axis of said coil, the frequency of the energy being such as to cause the energy to be guided by said coil along its axis, a receiver for transmitted microwave energy, and a detector for indicating a reduction in received energy at the receiver caused by intrusion into or disruption of the energy guided path determined by said coil.
An extensible and retractable barrier panel comprising a plurality of linear lengths of strip material of substantially uniform size, each strip length being reversely folded at successive fold points along the strip length and providing a sawtooth profile, the fold points of each strip intermediate opposite end strips being permanently fixed in alternating succession along the strip length to corresponding fold points of adjacent trailing and leading strip lengths.
A combined physical barrier and intrusion detection system comprising a metal barrier formed of at least one substantially constant diameter helical coil extending between two locations, a microwave energy source for directing said energy along the axis of said coil, the frequency of the energy being such as to cause the energy to be guided by said coil along its axis, a receiver for transmitted microwave energy, and a detector for indicating a reduction in received energy at the receiver caused by intrusion into or disruption of the energy guided path determined by said coil.
A barrier coil extensible and retractable about its central axis and comprising a continuous strip of coiled material, the coil having opposite terminal end turns and a plurality of intermediate turns of substantially uniform size, the continuous strip defining a major surface which in its width direction is generally parallel to that of an adjacent turn of the coil and which in the length direction of such major surface presents a continuous face extending longtiudinally along the length of the strip, the strip having barbs forming in spaced relation to one another along the length of the strip to protrude laterally outwardly from an edge of the major surface of the strip, each intermediate turn of the coil being permanently fixed at a first point to an adjacent trailing turn of the coil and at a second point to an adjacent loading turn of the coil such that each intermediate turn of the coil is permanently fixed at mutiple coil attachment points in circumferentially spaced succession, alternately, to adjacent trailing and leading turns of the coil, the number of coil attachment points on each intermediate turn of the coil being an odd number.
