Definitions

  • the present invention relates to a lifesaving rope, and more particularly, to a lifesaving rope being much more extendable owing to its great elasticity.
  • a lifesaving rope is one of refuge equipments, and it is generally used with installation in a descending life line of a multistory building, or it is utilized with connection to rescue tubes during sea-rescue work.
  • a representative example of the rope is illustrated in FIGS. 6 and 7 .
  • the conventional rope 10 is comprised of a core 11 , an outer cover 13 and a connecting cord 15 .
  • the core 11 is for withstanding the given load, and it is made in a way that strings or thin and long scraps of cloths or a bundle of fibers are weaved in X-shape.
  • the outer cover 13 is for protecting the core 11 and for additionally withstanding the given load, and it is made in a way that materials such as strings, thin and long scraps of cloth or a bundle of fibers are weaved in X-shape.
  • the connecting cord 15 is for connecting the core 11 and the outer cover 13 to a connecting hook (not shown), and it has one end which is sewed together with the core 11 and the outer cover 13 .
  • the conventional lifesaving rope 10 having the above-mentioned structure will be longitudinally extended when a load is given thereto owing to an elasticity of the core 11 and the outer cover 13 and the weaving structure in X-shape.
  • the conventional lifesaving rope 10 has a structure weaved in about 30° ⁇ 40° slope( ⁇ ), and therefore the total extendable amount thereof is not over 2 times even if it is extended until the slope( ⁇ ) to be 15° ⁇ 20°. Therefore, it is required relatively very long ropes, which requires relatively large keeping space and causes inconvenience in conveyance.
  • the present invention is created to solve a problem of the above-mentioned prior art, and accordingly the object of the present invention provides a lifesaving rope enabling to be extended over 4 times by getting a weaving structure of a core and an outer cover to have a slope of about 70° ⁇ 80°, by closely wrinkling the outer cover in longitudinal direction, and by longitudinally inserting a plurality of elastic strings into the outer cover in a constant interval according to the circumference of the outer cover.
  • the present invention provides a lifesaving rope comprising a core for withstanding a given load; and an outer cover for protecting the core and for additionally withstanding the given load, wherein the outer cover is relatively closely wrinkled in longitudinal direction thereof.
  • the core and the outer cover may be weaved in X-shape to have the slope of 70° ⁇ 80°.
  • a plurality of elastic strings may be inserted into the outer cover in longitudinal direction thereof to have a constant interval according to the circumference thereof.
  • the core may be folded in double in its width direction.
  • the core may be formed by laminating two cores having same size.
  • the core may be formed by inserting one core into another core.
  • the core may be made of any one of Aramid based such as kervlar, twaron and starbond, Poly-ethylene based such as dyneema, spectra, polyester, nylon 6, nylon 66, or Poly-ethylene based including polypropylene, carbon fiber or glass fibers.
  • Aramid based such as kervlar, twaron and starbond
  • Poly-ethylene based such as dyneema, spectra
  • polyester such as nylon 6, nylon 66
  • Poly-ethylene based including polypropylene, carbon fiber or glass fibers.
  • the outer cover may be made of any one of carbon fibers, glass fibers, mono fibers or rubber hoses.
  • the lifesaving rope can be extended over 4 times since a weaving structure of a core and an outer cover has a slope of about 70° ⁇ 80°, the outer cover is closely wrinkled in longitudinal direction, and a plurality of elastic strings are inserted into the outer cover in a constant interval according to the circumference of the outer cover.
  • FIG. 1 is a view schematically illustrating a lifesaving rope according to a preferred embodiment of the present invention
  • FIG. 2 is a view schematically illustrating one representative example of the core in FIG. 1 ;
  • FIG. 3 is a view schematically illustrating another example of the core in FIG. 1 ;
  • FIG. 4 is a view schematically illustrating still another example of the core in FIG. 1 ;
  • FIG. 5 is a view schematically illustrating the weaving structure of the outer cover or the core in FIG. 1 ;
  • FIG. 6 is a view schematically illustrating a conventional lifesaving rope
  • FIG. 7 is a view schematically illustrating the weaving structure of the outer cover or the core in FIG. 6 .
  • FIG. 1 is a view schematically illustrating a lifesaving rope according to a preferred embodiment of the present invention.
  • the lifesaving rope 100 comprises a core 110 , an outer cover 130 and a connecting cord 150 .
  • the core 110 is for withstanding the given load, and it is made in a way that thin and long materials are weaved in X-shape to have relatively narrow and close intervals.
  • Aramid based such as kervlar, twaron and starbond, poly-ethylene based such as dyneema, spectra, polyester, nylon 6, nylon 66, or high tenacity such as polypropylene are preferably applied as material of the core 110 .
  • carbon fibers or glass fibers can be applied to meet an exterior condition such as high tensile force, the coefficient of expansion, thermal endurance, the chemicals resistance, ultraviolet rays and humidity by considering the characteristics of industrial fields.
  • the core 110 as illustrated in FIG. 2 , is folded in double in its width direction.
  • the load which the core 110 can withstand can be increased and the core 110 is much easily inserted into the cylindrical outer cover 130 because the core 110 is not very soft.
  • the core 110 ′ can be twofold, as shown in FIG. 3 , by laminating two cores having same size, or as shown in FIG. 4 , by inserting one core 110 b into another core 110 a.
  • the outer cover 130 is for protecting the core 110 and for additionally withstanding the given load, and it is made in a way that thin and long materials are weaved in X-shape to have relatively wide intervals. Also, the outer cover 130 is relatively closely wrinkled in longitudinal direction thereof, and a plurality of elastic strings 111 are inserted into the outer cover 130 according to the circumference of the outer cover 130 . Like this, the outer cover 130 can be extended over 4 times with respect to the prior art by being extended 2 times owing to the weaved structure thereof and by being further extended 2 times owing to the wrinkle thereof and the elastic strings 111 .
  • the outer cover 130 can be preferably made of any materials having sufficient elasticity.
  • the outer cover 130 can be applied with carbon fibers, glass fibers, mono fibers, or rubber hoses even they do not have elasticity so as to meet a condition of industrial field.
  • the connecting cord 150 is for connecting the core 110 and the outer cover 130 to a connecting hook (not shown), and it has one end which is sewed together with the core 110 and the outer cover 130 .
  • the core or the outer cover of this embodiment is weaved to have the slope ( ⁇ ′) which is greater than that of prior art.
  • the slope ( ⁇ ′) is about 70° ⁇ 80°, which is about 2 times of prior slope ⁇ of about 30° ⁇ 40°. Therefore, when the slope ⁇ ′ is about 15° ⁇ 20°, as afore-mentioned, the lifesaving rope of the present invention can be extended up to 2 times with respect to the prior art.
