Definitions

  • the present invention relates to a security device, and in particular to a device which can be applied to an elastic rope for jumping sports or game/sport playgrounds, such as for example the "bungee jumping", fairs or amusement machines, for improving the security during the use.
  • the present invention also relates to an elastic rope comprising said security device.
  • the known elastic ropes comprise a bundle of elastic threads with the ends provided with fixing members for anchoring one or more persons to the rope and hanging the rope to a support structure.
  • a security strip is fastened to the fixing members for preventing an accidental separation thereof, i.e. the fall of the mass supported by the rope, in case of breaking of the bundle of elastic threads.
  • the stumps of these elastic threads may violently hit the user and/or the persons in the vicinity, so as to hurt them.
  • the device according to the present invention can contain the stumps of any broken elastic thread of an elastic rope, which therefore is not dangerous in case of a total or partial breaking of the bundle comprising these threads.
  • Said hose can comprise particular reticular structures for allowing the inspection of the state of the elastic threads contained therein.
  • the hose can have a high tensile strength against the breaking, so as to accomplish the task of the security strip for substituting it or reinforcing it anyway, in case of breaking and/or excessive elongation of the elastic threads.
  • the hose can also be made of particular materials, so as to be resistant, light and/or easy to be manufactured, sewn and/or coupled with an elastic rope, also of the known kind.
  • a known elastic rope comprises a bundle 1 of elastic threads with the ends provided with fixing members 2, 3, for example reels, plates, bars, rings, hooks, snap-hooks or the like, for anchoring one or more persons or other bodies to the rope and/or hooking the rope to a support structure.
  • a security cable 4 for example a nylon strip, which is substantially inelastic and has a length substantially equal to the length of the maximum useful elongation, i.e. the maximum elongation in normal conditions of use, of bundle 1, can be fastened and/or joined to the fixing members 2, 3 for preventing an accidental separation of the fixing members 2, 3 in case or breaking of the elastic threads of bundle 1.
  • a hose 5 which is substantially inelastic and has a length substantially equal to or greater than the length of the maximum useful elongation of bundle 1, is fastened and/or joined to the fixing members 2, 3, for example by means of eyelets, laces or bands, and envelops bundle 1.
  • hose 5 has a reticular structure made of polypropylene, preferably with a square weft having a side L comprised between 3 and 6 cm and a diameter comprised between 4 and 8 mm, as shown in figure 4.
  • the maximum tensile strength of the net of hose 5 is preferably greater than 200 Kg/m 2 .
  • hose 5 passes from a slack conformation to a stretched conformation, shown in figures 5 and 6.
  • hose 6 comprises a net closer than the previous one, in particular made of polyethylene with a square weft having a side comprised between 1 and 3 mm and a diameter comprised between 0,1 and 2 mm.
  • hose 7 is free from the security cable 4, is made of a material comprising carbon and/or aramide fibers, for example Kevlar®, and has a maximum tensile strength greater than 17 kN.
