Definitions

  • the present invention relates to a protection fence and a method for the realisation of such fence.
  • fences designed to protect a given area in order to prevent the access to non-workers and at the same time protect them.
  • Such fences are often used both in the industrial and in the civil field to delimit, for example, the machines working areas, the perimeter of the plants or the perimeter of the buildings intended for residential use.
  • the protection fences provide a series of panels, generally comprising a portion of metal mesh, associated by means of connection devices according to a determined spatial geometry.
  • the connection devices comprise multiple of supporting members of the uprights or stands type properly equipped to be constrained to the opposite sides of each panel so as to make the fence.
  • the panels are constrained to the uprights by means of screw connection means.
  • the patent FR 2 864 570 illustrates, e.g., a fence comprising at least one metal mesh panel associated with one pair of uprights defining respective longitudinal channels for the hooking of opposite ends of the panel.
  • the panel is connected to the pair of uprights by respective locking plates arranged behind the mesh constituting the panel. Each locking plate is fixed to the respective upright by screw means.
  • US patent 4,723,759 describes a protection fence comprising a series of metal mesh panels constrained to the uprights by jaw members, each jaw member comprising a first C-shaped jaw surrounding an upright and a second C-shaped jaw which wraps around a longitudinal wire of the panel.
  • the pair of jaws are joined at end portions by screw means.
  • JP Patent 2015 161121 illustrates a mesh panel that conforms at the top a bent portion facing downwards in a mounting position.
  • Each upright has at its top a covering member provided with a support element which protrudes towards the panel so as to function as a support for the bent portion of the panel.
  • the panel is fixed to each upright by a series of fixing members which are distributed along the longitudinal edges of the panel facing towards the respective uprights.
  • a problem related to the use of screw means is that of difficult assembly resulting in a consequent increase in the time required to perform the work and therefore the related labour costs.
  • the patent application EP 2 460 952 illustrates, e.g., a fence comprising a series of mesh panels, wherein each panel is associated at opposite sides to respective uprights having a series of hook members, laterally protruding towards the mesh panels.
  • the hook members are suitable for housing the longitudinal wires of the mesh panel placed at the lateral ends of the panel itself; such hook members are alternated with openings arranged to receive the end portions of the transverse wires of the mesh.
  • the uprights are H-shaped with end portions bent in order to define a curvilinear surface.
  • the bent portions extend at regular intervals along a longitudinal direction of the upright to form proper hooks suitable for retaining the longitudinal wires of the mesh panels.
  • the patent EP 1 980 688 illustrates a tubular upright comprising a first half-shell conforming at the ends respective protruding portions provided with hooking tabs.
  • the upright comprises a second half-shell likewise conforming a pair of protruding portions of ends provided with tabs suitable to be associated with the tabs of the first half-shell to form, during assembly, the tubular enclosure of the upright.
  • the protruding portions in the assembled configuration of the enclosure, define one pair of longitudinal guides adapted to receive the longitudinal wires of the mesh constituting the panel to be associated with the upright.
  • the object of the present invention is that of solving the above-mentioned problems, devising a protection fence allowing to optimize the assembly times.

  • Each said protection member comprises a cross-member which surrounds said respective supporting member on top and at the sides defining a region of space between said protection member and said supporting member suitable for hooking said at least one panel, said protection member being arranged to prevent the removal of said at least one panel.
  • the protection member comprises a first wall which extends above said supporting member and a second and third wall which constitute the sides and surround laterally said supporting member.
  • the second and the third lateral walls are fixed to the upright by welding or by the use of mechanical connection means.
