Definitions

  • the present invention relates to a fence.
  • fences are made of various materials, e.g., wire or plate.
  • Materials of fences comprise steel, aluminum, wood or synthetic resin, etc.
  • Fences have abundant variations.
  • any conventional fence is generally equal to that of a material and insufficient. This is because an increase in the thickness of a fence increases the weight of the fence, which is adverse to the strength of the fence and also makes it difficult to transport and apply the fence. In addition, increasing the thickness of the fence increases the bulk thereof, which remarkably reduces the spatial efficiency for transport and storage of the fence.
  • An object of the present invention is to provide a lightweight thick fence having a high spatial efficiency for transport and storage and a high applicability.
  • a fence comprises a plurality of cross wires each of which extends lengthwise of the fence and has the form of a wave having the amplitude in the direction of the thickness of the fence, the cross wires being substantially in parallel to one another, two arrays of elongate vertical members, the arrays of elongate vertical members extending substantially in parallel to each other lengthwise of the fence with a predetermined spacing in the direction of the thickness of the fence, the elongate vertical members joining and being fastened to said cross wires, beam means placed in the spacing between said arrays of elongate vertical members, and a post joined to the beam means.
  • the cross wires provide a thickness to the fence. Removing the beam means from the fence enables the fence body to be compactly stacked, so that a stack of fence bodies requires a relatively small space. Since the corrugated cross wires of the fence provide the thickness to the fence, the weight of a fence having even a large thickness is small.
  • FIG.1 is a perspective view of the body X of a fence according to an embodiment of the present invention.
  • the fence comprises the fence body X, posts or supports Y and joints 6 joining the fence body X to the posts Y.
  • the fence body X comprises cross wires 1 made of a metal and vertical members or wires 2 made of a metal and joined to the cross wires 1.
  • the fence body X has the structure of a grid comprising the cross wires 1 and the vertical wires 2.
  • the vertical members may be in the form of pipe or rod. This form of the vertical members can strengthen the fence body X and reduce the number of cross wires 1.
  • each cross wire 1 is corrugated or periodically zigzagged so as to have the form of a triangular wave.
  • the exterior surface of each front angle 10 of each cross wire 1 has a single vertical wire 2 jointed thereto.
  • the interior surface of each rear angle 10 of each cross wire 1 has a single vertical wire 2.
  • a front array of vertical wires 2 and a rear array of vertical wires 2 are parallel with a predetermined spacing.
  • Each vertical wire 2 is fastened, e.g., by welding to the cross wires 1 to join all of the cross wires 1 in parallel to one another.
  • each vertical wire 2 reaches the top surface of the top cross wires 1 and terminates in a chamfer 20 of an angle ⁇ from the level of the top surface of the top cross wire 1.
  • the presence of the chamfer 20 enhances the safety in handling the fence and prevents a slippage of a paint applied to the chamfer 20.
  • the fence further comprises top and bottom beams 3 in the form of a rectangular pipe extending in the direction of the length of the fence body X between the front and rear arrays of vertical wires 2.
  • the outer width of each beam 3 is equal to a spacing between the front and rear arrays of vertical wires 2.
  • the upper beam 3 is in contact with and held down on the top cross wire 1a by means of a hold-down 15.
  • the lower beam 3 is in contact with and held down on the bottom cross wire 1d by means of the hold-down 15.
  • the hold-down 15 has a groove 16 extending in the direction of the cross wire 1 and receiving it.
  • a U-bolt or the like may be employed instead of or in combination of the hold-down 15.
  • each beam 3 may pass through the fence body X between the arrays of vertical wires 2 without any joining to the arrays of vertical wires 2 and the cross wires 1a and 1d.
  • beams 3 may be fixed to the arrays of vertical wires 2 instead of to the cross wires 1a and 1d.
  • the beams 3 may be fixed to the arrays of vertical wires 2 and to the cross wires 1a and 1d.
  • the fence body X is extendable and retractable in service lengthwise thereof to provide a cushioning effect to the fence since the beams 3 do not block a movement of the fence body X in the direction of the length of the fence body X.
  • the beam 3 may be placed intermediate the height of the fence body X instead of at the top and bottom of the fence body X.
  • the fence may comprise any number (e.g., more than two) of beams 3 if necessary.
  • the beam 3 has the form of rectangular pipe.
  • a C- or lip-channel steel of C-shaped section the bottom side of which has slot 30 extending lengthwise of the C-channel steel may constitute the beam 3 as shown in FIG.5B.
  • FIGS.5A and 5B when the beam 3' of C-channel steel is mounted to the fence body X, the beam 3' is first placed in the fence body X in such a manner that the slot 30 is opposed to the rear array of vertical wires 2, and subsequently turned through 90° so that the slot 30 is positioned in the bottom of the beam 3'.
  • the slot 30 of the C-channel steel causes the beam 3' to be easily flexed, so that the flexibility of the beam 3' facilitates the rotation of the beam 3' from the position of FIG.5A to the position of FIG.5B.
  • the beam 3' of C-channel steel allows the hold-down 15 to be secured to the beam 3 with bolts and nuts in the interior of the beam 3'.
  • the beams 3 may be made of round pipe rod or a bar.
  • the beams 3 may be made of wire as described later.
  • the hold-down 15 joins the beam 3 to the cross wire 1.
  • the beam 3 may alternatively be fastened to the cross wire 1 using a spacer 5. Both the hold-down 15 and the spacer 5 may alternatively be employed in order to fasten the beam 3 to the cross wire 1.
  • the spacer 5 has the form of a rectangular pipe cut with the length equal to the thickness of the fence body X. The spacer 5 fitted between the beam 3 and the adjacent cross wire 1 to fix the beam 3 between the adjacent cross wires 1, 1. Corresponding spacers 5 are placed in the fence body X lengthwise of the fence body X with predetermined spacings.

  • a cross wire 1b is added to the fence body 1 immediately below the top beam 3 and supports the top beam 3 from below.
  • both the hold-down 15 and the cross wire 1b may be employed in order to hold down the top beam 3.

  • the top and bottom ends and intermediate or intermediates of the fence may comprise corresponding pairs of corrugated wire beams 39' if necessary.
  • top edge surfaces of the vertical wires 2 are in contact with and welded to the underside of the corrugated beam 39, no top edge surfaces of the vertical wires 2 are rusted and the strength and the appearance of the fence do not degrade.
  • the arrangements of fence described above have the following advantages:
  • the combinations of the corrugated cross wires 1 and the vertical wires 2 provide three-dimensional fence bodies X having a large thickness and increase the strength of the fence bodies X.
  • the arrangements of the fence enhances the aesthetic value of the appearance of the fence.
  • the beams 3 increases the strength of the fence body X.
