Definitions

  • the present invention relates to a fencing system consisting of a wire netting sheet, fixing posts as well as clamping means for fixing the wire netting sheet to the posts, whereby each post is provided with a bulge substantially extending in longitudinal direction thereof that serves as bearing surface for the netting sheet to be fixed and for fixing the netting sheet with several clamping means and whereby each of the clamping means consists of a deformable piece that can grip round the bulge of the post taking up and clamping at least one wire part of the netting sheet to be fixed.
  • Such a fencing system with clamping means is known from the Dutch patent application 8600065 in the name of the applicant.
  • the used clamping means in the form of bent metal wire ends are pinched round the bulge of the post by means of pincers, in which process they take up and fix a wire part of the netting sheet to be fixed.
  • these bent metal wire ends cannot be used several times, as a metal wire end breaks after having been bent a number of times and it furthermore being time-consuming to work with used wire ends.
  • these wire ends are sharp and may consequently inflict bodily harm to people or animals if they get caught on such pinched metal wire ends. One may also get injured taking off the clamped metal wire ends in order to remove the fencing.
  • the invention aims to provide a solution to the above-mentioned disadvantages.
  • the fencing system according to the invention is characterized in that the clamping means consists of elastically deformable, synthetic material of elongate shape having a cylindrical outside and inside surface, a slot-shaped recess extending longitudinally along said clamping means for gripping round the bulge of the post and at least one slot-shaped wire recess extending in a direction deviating from the direction of the longitudinal axis of said clamping means (1) for taking up and clamping a wire part of the netting sheet.
  • clamping means are elastically deformable, they can be fitted and removed many times and when properly carried out they cannot inflict bodily harm.
  • the synthetic material to be used for the clamping means can for instance be polyethylene, polypropylene, nylon or polyoxymethylene, whether or not reinforced with fibres such as glass fibre.
  • the cylindrical outside and/or inside surface is not necessarily understood to mean a circular cylindrical surface.
  • the cylindrical outside and/or inside surface can also present a regular polygon or other shapes.
  • the clamping means described hereinabove can be used in a very simple way to clamp a wire part of a netting sheet to the described post. This fixing can be carried out manually or by means of tools.
  • the axis of the cylinder defining the inside surface of the clamping means is displaced in a direction perpendicular to the axis of the cylinder defining the outside surface of the clamping means such that a clamp wall of differing thicknesses (d1, d2) results.
  • the wall thickness taper thus obtained greatly enhances the clamping action of the clamping means in accordance with the present invention.
  • the slot-shaped wire recesses extend at right angles to the cylinder axis.
  • the slot-shaped recesses extend in such a way with respect to the cylinder axis, that when the clamping means grips round the bulge of the post, they can take up and clamp a wire part of the netting sheet.
  • the clamping means grips round the bulge of the post, they can take up and clamp a wire part of the netting sheet.
  • the slot-shaped wire recesses have a width that substantially corresponds to the diameter of the wire applied in the netting sheet.
  • the slot-shaped wire recess should not be larger nor smaller than the diameter of the wire applied in the netting sheet. Too large a width of the slot-shaped wire recesses gives too much play to the netting sheet and too small a width of the slot-shaped wire recesses makes it impossible to tighten the netting sheet as the wire is then jammed in the slot-shaped wire recesses.
  • the slot-shaped wire recesses comprise hollows at their closed ends, which can take up a wire part with play.
  • the slot-shaped recess extending in axial direction comprises end planes that with the clamping means in clamping condition rest against a surface of the post.
  • the bulge be located on a flat part of the post that substantially extends longitudinally of the post and is parallel to the post axis and that the end planes of a clamping means in clamping condition rest against said flat part.
  • Figure 1 represents a fencing comprising a wire netting sheet, fixing posts as well as clamping means in accordance with the invention.
  • Figure 2 represents, in perspective, a clamping means in accordance with the present invention.
  • Figure 3 represents a section through a post with bulge and through a clamping means, a wire part being fixed to the post by means of the clamping means.
  • Figure 4a represents a view from above of a clamping means in accordance with the present invention in nonclamping condition.
  • Figure 4b represents a side view of the clamping means in accordance with the invention represented in figure 4a.
  • Figure 5a represents a view from above of another embodiment of a clamping means in accordance with the present invention, the thickness of which decreases in the direction of the axially extending slot-shaped recess.
  • Figure 5b represents a side view of the clamping means from figure 5a in accordance with the invention, comprising hollows.
  • Figure 6a represents a view from above of yet another embodiment of a clamping means in accordance with the present invention, the clamping means being provided with a recess or hollow for a pin to be fixed therein.
  • Figure 6b represents a side view of the clamping means from figure 6a in accordance with the present invention, with the pin fixed in the recess or hollow.
  • Figure 1 represents part of a fencing system according to the invention comprising a wire netting sheet 3, fixing posts 2 as well as clamping means 1.
  • Figure 1 particularly shows the clamping means 1 in conjunction with a wire part 4 of the netting sheet 3 and the vertical bulge 7 of the post 2.
  • the clamping means 1 is shown on a larger scale in figure 2.
  • Such a clamping means can generally be made of tubular material.
  • Tubular material is not necessarily understood to mean a circular cylindrical object.
  • the outside and inside surface of the tubular material can also present a regular polygon or another shape.
  • a number of exemplary materials are polytetrafluoroethylene, polyethylene, PVC, polypropylene etc. ... .
  • Figure 3 clearly shows that a netting sheet 3 tightened in the direction of the arrow P1 cannot slacken again because the vertical wire part 4′ rests against the clamping means 1.
  • the netting sheet 3 is tightened in the direction of the arrow P1 so that the wire part 4′ comes well to the left of the bulge 7, whereupon the clamping means 1 is hit over the bulge 7 and the horizontal wire part 4 by means of a hammer.
  • the netting sheet 3 is taut and this tension is maintained because the wire part 4′ ends up resting against the clamping means 1.
  • the arrow P2 indicates the tension in the taut netting sheet.
  • the netting sheet 3 used in these examples only has vertical 4′ and horizontal 4 wire parts. Nonetheless, it is quite possible to use a netting sheet that has a different pattern such as rhombic netting, hexagonal netting etc...
  • the clamping means to be used for these nettings falls completely within the scope of the present invention, as this is only a variation of the described clamping means that is obvious to the skilled worker.
  • the figures 4a and 4 b enclosed herewith are given by way of illustration of the shape of the clamping means in accordance with the present invention.
  • Figure 4a shows the clamping means in accordance with the present invention as viewed from above
  • figure 4b shows the clamping means as viewed from the side.
  • the end planes 5′ of the recess 5 in figure 4a are for increasing the friction between the clamping means 1 and the post 2 when the clamping means 1 encloses the bulge 7 of the post 2 while taking up and clamping a wire part 4. If this friction is inadequate, the netting sheet 3 may sag under the pressure of for instance the neck of cattle grazing over the fence or persons stepping over the fence.
  • FIG. 5a illustrates the eccentricity described in claim 2 of the cylindrical inside surface with respect to the cylindrical outside surface of the clamping means 1.
  • This embodiment of the clamping means has a greater clamping action than a clamping means with constant thickness of wall (fig. 4a). Even though they are not shown, end planes 5′ may also be present here as represented in figure 4a.
  • FIG. 5b The embodiment where hollows 8 are present is shown in figure 5b.
  • the clamping means 1 can be slipped so far over a wire part 4 that the wire is taken up in hollow 8.
  • the hands of the user can be withdrawn, whereupon the clamping means 1 can be hit over the bulge 7 by means of a hammer. This precludes possible injury by mishitting.
  • Figures 6a and 6b represent yet another embodiment of a clamping means 1 in accordance with the invention.
  • the clamping means 1 represented in figure 2 with a protruding pin 10 so that the clamping means can be held by this pin when fitting it on the bulge 7 of the post 2 thus avoiding that the user's hand is hit when hitting with the hammer on the clamping means 1.
  • the clamping means 1 with a small recess or hollow 9 for the fitting therein of a pin 10 in order to facilitate the fitting of the clamping means 1 on the post 2.
  • the clamping means in accordance with the present invention have particularly good properties for fixing a netting sheet to posts provided with a bulge substantially extending longitudinally thereof.
