Definitions

  • the present invention relates generally to safety fences erected along highways and'the like roads to separate the various lanes and stop any vehicle which may leave its lane, and more particularly to an improved cable used such fences.
  • the present invention overcomes these shortcomings. It relates to an improved cable, used in making safety fences to be erected along highways and like roads, which is characterized by the fact that all the strands which make up the cable are embedded in a coating of plastic or other suitable material which results in a smooth outer cylindrical surface.
  • the coating made of polyethylene, rubber or vinyl derivatives or other suitable substances, is a coating which is extruded around the metallic part of said cable.
  • the metallic part of the cable is preferably made up of a central strand, composed of a plurality of wires, and a plurality of other strands, wound helicoidally around the central strand.
  • the extruded coating surrounds all the strands and fills in the cavities between the strands, and between the various wires.
  • the cable provided with this coating can be bent around a cylinder of a diameter equal to at least four times the one of the cable without tearing the coating to pieces or breaking one of the wires which makes up the cable.
  • FIG. 1 is a perspective view, partially in section, of the cable made in accordance with the invention.
  • FIG. 2 is a cross-section taken along the lines 22 in FIG. 1;
  • FIG. 3 is a view of the minimum curvature to which a cablecan be subjected without being damaged.
  • the cable is made up of a metallic part A embedded in a coating B which is extruded around said part.
  • Metallic part A is made up of a longitudinal central strand T and of a plurality of strands T wound helicoidally around the central strand T
  • FIG. 1 of the drawing shows six strands T symmetrically arranged around strand T
  • Each of strands T and T are composed of a plurality of steel wires 1, wound helicoidally.
  • the steel used for wires 1 may be a carbon steel of which the physical properties are the following ones:
  • the strands may also be composed of 7 wires of a diameter approximately equal to 1 mm.
  • Coating B may be made of any extrudable material, such as polyethylene, natural or synthetic rubber or a vinyl derivative or other suitable material.
  • the cable made up of a longitudinal strand and six peripheral strands symmetrically arranged around the core, composed of the central strand, has proved to be an excellent one for obtaining a good penetration of the coating into the interstices of said cable, as shown in FIG. 2, achieving a very strong adherence of the coating to the metallic part of the cable.
  • a coating of this type enables a cable so coated to be bent, as shown in FIG. 3, through an angle, equal to around a cylinder a having diameter E equal to four 3 times that of D of the coated cable, without breaking the coating B or breaking one of the wires 1. Consequently, the part of the cable struck by'the motor vehicle resists breaking.
  • the coating B also reduces the loss of resistance of the cable, resulting from winding the cable so that the resistance of the composite cable is increased as compared to a conventional all-metal cable of the same dimensions.
  • a cable used in safety fences erected along highways or like roads comprising a central core, a plurality of strands wound around said core, and a coating, said coating surrounding said core and said strands whereby the coating fills in the spaces between said core and said strands and covers the outside of said cable.
  • a cable according to claim 2 wherein said strands comprise a central wire and a plurality of wires wound around said central wire, said coating surrounding all of said wires.
  • a cable according to claim 1 said coating being made of plastic material.
  • a cable according to claim 4 said coating being made of plastic material.
  • a safetyfence for a highway or like road comprising at least one cable, said cable comprising a central core, a plurality of strandswound around said core, and a coating consisting of a substantially shock absorbing material, said cable substantially embedded in said coating, said coating providing said cable with a continuous, smooth surface and means simultaneously filling the spaces between said strands and said core.
