Definitions

  • the present invention relates to a new strip for obtaining a barbed member.
  • the strip for obtaining a barbed member made by pulling on the strip itself is characterized in that, at regular intervals, and starting from the two lateral edges of the strip, are made lateral cuts each consisting of an oblique fu'st cut emerging on the lateral edge, a second cut appreciably parallel to said lateral edge and communicating with the end of said first cut, and a third cut extending from the free end of this second cut to the vicinity of the longitudinal axis of the strip, said lateral cuts being combined with median cuts extending between two successive sets of lateral cuts, said median cuts each having a longitudinal portion from whose ends there extend two portions of cuts limiting appreciably triangular parts, the successive lateral cuts and median cuts making full zones in the strip appreciably extending according to two sine curves whose alternations are opposed, so that at least the tops of said sine curves are deformed by twisting, when the strip is stretched out whereby resulting that the zones extending between the various cuts, both lateral and median, are made to project in different plane
  • FIG. 1 is an elevation of a strip for obtaining the barbed member of the invention in its closed position.
  • FIG. la is a similar elevation to FIG. 1, showing a modification.
  • FIG. 2 is a perspective view of a section of the member of FIG. during its extension.
  • FIG. 3 is a perspective view still showing the same member, completely opened out.
  • the barbed member of the invention is made from a continuous strip designated on the whole by I and of which only one segment appears in the drawing.
  • the strip 1 has several distinct sets of cuts symmetrically shaped in relation to the two lateral edges 2 and 3 of the strip and these sets of cuts are symmetrically repeated right along the strip.
  • the first set has an oblique cut 4 emerging on the edge 2, a second cut 5 appreciably parallel to said edge 2 and intercepting the end of the cut 4, said cut 5 being shorter than the cut 4, and a cut 6 approximately perpendicular to the edge 2 and extending from the end of the cut 5 opposite to that which intercepts the cut 4 up to a certain distance from the longitudinal median axis of the strip 1.
  • the same cuts 4a, 5a, 6a are made in a strictly symmetrical manner in relation to the longitudinal axis of the strip 1.
  • the same cuts as those described above are reproduced at regularly spaced-out intervals as shown at 4,, 5,, 6,, on the one hand, and 4a,, 5a, and 6a,, on the other.
  • This second set of cuts comprises a longitudinal section 7 made along the axis of the strip and whose ends communicate with two oblique cuts 7a, 7b which themselves communicate with two cuts 8a, 8b aligned with each other and perpendicular to the longitudinal axis of the strip.
  • the sets of median cuts comprise a supplementary cut 9a, 9b which, with the cuts 8a, 8b limits triangular spikes l0 and 11 connected to triangular spikes 12 and 13 opposed to one another and limited between the cuts 7, 7a, on the one hand, and 7, 7b, on the other.
  • the sets of lateral cuts also comprise a supplementary cut 14, 14a communicating with the free end of the cuts 6, 60 so that one limits two triangular spikes 15, 15a facing each other and which are connected to lateral zones of lozenge-shape designated by the reference numerals l6 and 160, which lateral zones are limited by the edges 2 and 3 respectively and by the cuts 4, 4,, 4
  • Cuts 17 and 17a of fishhook shape are made from the end of the cuts 6, 6a nearest to the longitudinal axis of the strip in order to limit hooks 18, 18a facing each other, against said cut 6
  • the hooks I8 and 18a are strictly symmetrical in relation to the longitudinal axis of the strip 1
  • the hooks, then designated by the reference numerals 28, 28a although directed towards each other, have their respective direction opposite one another, to facilitate their engaging, as will be seen in what follows.
  • FIG. 2 shows the strip when it begins to be opened out and that the lozenge-shaped zones 16, 16a are separated from each other progressively as the amplitude of the sine curves A and B increases.
  • the zones 16 and 16a pivot in relation to the initial plane of the strip because the parts A,, B, and C, of the above-mentioned sine curves are subjected to a twist, due to the lengthening of the strip.
  • the amplitude of the sine curves A and B increases, the height of their alternations decreases, and consequently, the hooks I8 and 18a of FIG. 1, or 28, 28a of FIG. 1a and FIGS. 2 and 3 are brought closer together.
  • the base of hooks being supported by the zones 16 and 16a which are subjected to a pivoting movement during opening out, it follows that said hooks progressively pivot as they come closer together.
  • the books When the strip has undergone a sufficient opening out, as shown in FIG. 3, then the books not only come into contact with one another, but also, they are engaged by their respective barbs, so that they make bolts for the opened-out member which has been lengthened while preventing this member from resuming its initial position if one ceases to exert a pull on it, even when the twisting deformation undergone by the parts A,, B, and C, is only a deformation within the elastic limit of the material of which the strip is made of steel for making a barbed member to be used for defensive purposes.
  • FIGS. 2 and 3 show that the zones 16 and 16a are not the only ones pivoting in relation to the initial plane of the strip.
  • the triangular parts l0, 12, on the one hand, and 1 l, 13, on the other, which are limited by the sets of median cuts, have their bases contiguous to the parts C, subjected to a twisting deformation, so that these triangular parts also project at this moment in different directions while forming sharp-pointed members.
  • This also applies to the triangular shaped parts which are joined in the vicinity of their bases to the parts A B of the sine curves, and consequently, said triangular parts 15 and 15a also project in other directions for also making sharp-pointed members.
  • the form of the hooks 28, 28a of FIG. la is generally considered more advantageous than that of the hooks 18, 18a of FIG. 1, because the mutual engaging of said hooks 28, 28a takes place spontaneously at the moment when the strip is extended, whereas in the embodiment of FIG. 1, it is advisable in order that this mutual engaging takes place without fail, to impart a certain twist to said hooks at the same time that the cuts are made.
  • This operation can nevertheless be useful when the barbed member is to be used for military defence, for then its efficacity is increased by providing, as shown in FIG.
  • the various projectings parts will, on the contrary, preferably be founded so as to avoid all risk of in ury.
  • the member described in the foregoing can be made from strips of very variable widths.
  • the strip is made of a ribbon a few centimeters wide, for instance, a strip with a width comprised between one and five centimeters.
  • the barbed member of the invention can nevertheless be put into operation for producing much larger members, for making portable wire entanglements.
  • the strips used can be steel strips several tenths of centimeters wide. The extension of said members is effected on the spot where they are to be used.
  • Strip for obtaining a barbed member made by pulling on the strip itself, in which, at regular intervals, and starting from the two lateral edges of the strip, are made lateral cuts each consisting of an oblique first cut emerging on the lateral edge, a second cut, appreciably parallel to said lateral edge and communicating with the end of said first cut, and a third cut extending from the free end of this second cut to the vicinity of the longitudinal axis of the strip, said lateral cuts being combined with median cuts extending between two successive sets of lateral cuts, said median cuts, each having a longitudinal portion from whose ends there extend two portions of cuts limiting appreciably triangular parts, the successive lateral cuts and median cuts making full zones in the strip appreciable extending according to two sine curves whose alternations are opposed, so that at least the tops of said sine curves are deformed by twisting when the strip is stretched out whereby resulting that the zones extending between the various cuts, both lateral and median, are made to project in different 2.
  • Strip according to claim 1 characterized in that supplementary cuts of fishhook shape are made near to the third cut of each set of lateral cuts for limiting two hooks opposite to each other which are made to coincide with one another when the strip is extended, so that said hooks keep said strip in an opened-out state for which the zones limited by the various cuts project in different planes.
  • Strip according to claim 2 characterized in that the hooks are made symmetrically in relation to the longitudinal axis of the strip and in that they are subjected to twisting so that they fit into each other.
  • Strip according to claim 2 characterized in that the hooks are made to face each other but in opposite directions.
  • Strip according to claim 1 characterized in that beginnings of cuts are made in the various parts limited by the cuts and in that the parts contiguous to said beginnings of cuts are bent like a jagged-set tooth saw.
  • Strip according to claim 1 characterized in that the strip is made of resilient metal sheeting.
