Definitions

  • the present invention relates to an anchor element for a rope.
  • the said anchor element is particularly, but not necessarily, intended to act as an anchor for a rope or cable in boulder fences, snow nets or snow fences.
  • These systems essentially comprise a net held in place by means of ropes attached to a plurality of anchor elements fixed to the soil or a rock face by means of suitable fixing means.
  • anchor elements that is those elements designed to be fixed to the soil or a rock face and to which the ropes are then attached to keep the nets in place.
  • the environments in which the anchor elements are installed are hostile to their structural integrity: they are driven into the ground or rock face or otherwise in contact with the material of the soil or rock, and at the same time are exposed, at least as regards the part above the soil, to the weather.
  • the structural integrity of the anchor elements is undermined by corrosion phenomena due partly to humidity or water coming into contact with the metal parts of the element, and partly to electrolytic phenomena, for, as is known, the contact between the material of the soil or of a rock face and the metal that partly forms the anchor element generates an electrolytic cell capable of causing structural damage to the said element.
  • Certain products use a tube, generally made of plastic, in which the cable is inserted, to provide protection.
  • the need is felt, therefore, to provide an anchor element for rope capable of completely insulating at least a section of the cable of the anchor element from water or humidity.
  • the problem addressed by the present invention is that of devising an anchor element for rope whose structural and functional characteristics shall satisfy the abovementioned requirements and at the same time obviate the disadvantages discussed with reference to the prior art.

  • the said cable 1 is bent so that its central portion 4 forms an eye that will conveniently take the said rope attachment means.
  • the said means for attaching the rope to the anchor element 1 are, for example, an end section of the rope itself, suitably bent to form a noose, e.g. with the aid of clips, or a hook that connects onto the tie with shackles and the like.
  • the anchor element 1 also includes a second portion 16 designed to work together with means for fixing the said anchor element to the soil or to a rock face.
  • a first section 16' of the said second portion 16, in an installed configuration of the anchor element 1, is beneath a soil line t-t, that is, buried in the ground or in the rock face.
