Definitions

  • wire defense coils which consist of a wire Wound continuously according to a helical pattern and comprise between adjacent groups of a plurality of turns of same diameter one or more intermediate turns having a smaller radius of curvature.
  • a coil of this type has been developed with a view to prevent any longitudinal progression within the coil itself.
  • a coil of the type broadly set forth hereinabove is attended by many drawbacks.
  • the inner and outer defense networks are made from the same wire.
  • the wire pattern is not regular, so that inequalities in the network distribution are observed when the coil is spread or expanded, these inequalities constituting in many cases apertures facilitating the passage through the defense coil.
  • the inner defense network When spreading or setting the coil, the inner defense network is elongated and its diameter decreases, thus preventing any progression of an individual in the longitudinal direction within the network.
  • the mesh size of the inner network may be set at will, that is, by increasing or reducing the pitch of its turns, according to requirements.
  • the inner network may be caused to act either as a traction spring or as a compression spring. If the inner network constitutes a compression spring, it will thus compensate the tractive effort which must necessarily be exerted on the outer network during the spreading operation, so that means weaker than usual may be used for anchoring the coil on the ground. It is even possible to use the coil on grounds that will not hold conventional anchoring means for example on sand, etc.

  • FIGURE 2 is an end view of the defense coil of FIG. 1;

  • FIGURE 7 is another elevational view showing the complete defensecoil of FIG. 6, that is, incorporating-the inner network;
  • FIGURE 10 is a cross-sectional view taken upon the line X-X of FIG. 9;
  • FIGURE 11 is a longitudinal section of the winding drum or mandrel, after winding theouter network thereon and before stapling the turns thereof with one another and with those of the inner network;
  • FIGURE 12 is anend view taken from the left hand side of FIG. 11, showing the winding mandrel
  • FIGURE 13 is a diagrammatic front view showing the inner network
  • FIGURE 14 is an end view of the same network
  • FIGURE 15 is a diagrammatic view showing the stapling of the inner network to the outer network.
  • the defense coil illustrated diagrammatically in-its spread or operative condition comprises an outer network 1 and an inner network 2 coaxial to the outer network.
  • the inner and outer networks are illustrated in the form of a pair of helical coils; actually, as will be explained hereafter, the successive turns of each helix are hooked or stapled with one another .at certain points in order to impart a proper relative rigidity to the assembly.
  • the inner network 2 comprises a number of turns per unit length which is smaller than that of the outer network 1.
  • the inner defense network 2 forms a cylindrical body having a diameter D considerably smaller than, the diameter D of the outer defense network '1.
  • the inner network 2 is hooked at spaced intervals to the outer network 1 for example by meansof assembly wires such as 3 stapled or hooked at points 4 and 5 on the outer network 1 and inner network 2, respectively.
  • the stapling points 4, 5 may be distributed at .will along the networks 1, 2.
  • FIG. 2 shows these hooking points as located at the vertices of a regular pentagon, but it will be readily understood that any other arrangement may be used without departing from the spirit and scope of the invention. 7
  • the hooking or stapling wires 3" are dispensed with and replaced by a suitable alteration of the shape of some of the turns of the inner network 2.
  • one turn of the helix constituting the inner network 2 is elongated to form a curved outer portion 2a substantially tangent, at several points 6, 7, 8, 9, 10, to the cylinder on which the helix of the outer network 1 is formed.
  • the turn sections 20 are stapled or hooked at these points, 6, 7, S, 9, It on the outer network 1 to provide the proper connection between the two net works.
  • FIGS. 6, 7 show the front half of the coil in thick lines and the rear half in broken lines in order to facilitate the understanding of the structure.
  • the outer network 1 consists of a wire wound as a helix wherein the successive turns are stapled together at points 11, 12, 13, 14, constituting the vertices of a regular pentagon.
  • the number and distribution of these stapling points may differ from the example shown in this figure.
  • the inner network 2 is obtained according to the pattern illustrated in FIG. 8.
  • the successive turns of the inner network are assembled with one another at points 16, 17, 18, 19 and 20.
  • FIG. 7 it will be seen that when the defense coil is spread to its operative position the inner network 2 is elongated considerably more than the outer network 1, so that its diameter decreases and the inner network constitutes an eflicient protection against any longitudinal progression within the coil.
  • FIGS. 9 to 12 of the drawing there is shown diagrammatically an apparatus for forming a defense coil according to this invention.
  • This apparatus comprises a transverse flange 21 overhung from a shaft 22 adapted to be rotatably driven through any suitable means.
  • the flange 21 carries five longitudinal rods 23, 24, 25, 26, 27 supporting at their outer ends a transverse support consisting for example of a pentagonal member 28.
  • this apparatus is further provided with another assembly of five longitudinal rods 30, 31, 32, 33 and 34 carrying at spaced intervals guide plates 35 extending radially therefrom.
  • the rods -34 are each carried by the ends of two arms 36pivoted by means of pins 37 on the one hand on the aforesaid support 28 and on the other hand on the fiange 21.
  • the arms 36 are locked in position by pins 38.
  • the inner network is formed by winding as a helix a suitable wire engaging on the one hand the rods 23-27 and on the other hand the rods 3ti34. At regular intervals this wire is caused to pass over one of the guide plates so as to provide turn sections 2a elongated in the outward direction.
  • the successive turns are stapled with one another by means of staples or clips disposed at points 16, 17, 18, 19 and 21 as shown in FIG. 8.
  • the apparatus When the stapling of the inner network is completed the apparatus is prepared for winding the outer network 1. To this end an assembly of outer rods 40, 41, 42, 43 and 44 carried on the one hand by recesses formed in the flange 21 and on the other hand by connecting plates 45 secured on the vertices of the pentagonal support 28 are mounted on the apparatus.
  • the rods 40, 41, 42, 43, 44 are disposed on the same radii as the inner rods 23, 24, 25, 26, 27, respectively.
  • the operator Having thus mounted the outer rods 40-44, the operator winds the outer network 1.
  • the wire constituting this network passes over the outer rods 40, 41, 42, 43, 44 and also periodically over the guide plates 35 having already received the turn sections 2a of the inner network 2.
  • the successive turns of the outer network 1 are stapled with one another and the defense coil'is completed by stapling the turn sections 2a. to the outer network 1, preferably at or in close vicinity of the guide plates 35.
  • the pin 38 are removed and the different arms 36 are rotated about their pivot pins 37 in order to retract the guide plates 35 inwardly. Then the connecting plates 45 and outer rods 40-44 are removed, and the coil assembly can be removed from the winding mandrel.
  • the inner network consists of circular turns 21 having a diameter D and every third turn begins from successive points a, b, c of turns 22 closed by stapling at these points.
  • the starting point a, b, c of the free turns are shown in FIGS.
  • the points a, b, c are preferably shifted angularly from one another along a helix, as shown in FIG. 14, wherein the angle of shift is of the circumference from one point to another.
