Description

(54) IMPROVEMENTS IN OR RELATING TO PLASTICS MESH (71) We, TINSLEY WIRE (SHEFFIELD) LIMITED, a British Company of P.O. Box 119, Shepcote Lane, Sheffield S9 lTY, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following state ment :- This invention relates to plastics mesh and has for its object the provision of providing a plastics mesh capable of being rolled up for transport and storage an also capable of exhibiting at least some of the rigidity of a plastics-coated wire mesh.

According to the present invention, a plastics mesh comprises two series of parallel plastics filaments perpendicular to each other and united at their intersections, with all the filaments in one of the series being tubular and permanently fitted with rigid rods, and with the filaments in the other series being solid plastics and/or tubular plastics with open ends adapted to receive rigid rods when the mesh is in the flat condition.

The expression "rigid rods" includes wires of stiffness akin to those used in forming substantially rigid wire mesh.

The absence of rods from one series of plastics filaments enables those filaments to bend to allow the mesh to be rolled up for transport and storage, while the rods in all of the tubular plastics filaments of the other series affords the mesh some rigidity when in the flat condition. The absence of rods from one series of plastics filaments also enables those filaments to bend to allow the mesh to be formed into a cylindrical fencing enclosure, for use around trees, bushes or shrubs, especially young ones; and the rods in all the tubular filaments of the other series preferably project from the lower ends of the tubular filaments, to enable the rods to be pushed into the ground; also, the upper ends of the tubular filaments may be joined by linked semicircular loops of plastics material with spigots fitting into and secured (by welding or by adhesive) to the tubular filaments.

The two forms of plastics mesh as described above are suitable for forming fencing by choosing a suitable spacing (e.g. 10 cm pitch) and securing to posts at the usual intervals (e.g. 2 metres) for plastics mesh or plastics coated wire mesh fencing. They may also be used as mats or duck-boards to provide support for personnel or vehicles over swampy ground and one series of plastics filaments (intended to be uppermost) may be provided with treads.

However, with all the filaments in both series tubular and all the tubular filaments in one series permanently fitted with rigid rods while all the tubular filaments in the other series are open-ended, further rods can be inserted in all the open ended tubular filaments, perpendicularly to the permanently fitted rods, when the mesh is in the flat condition, thereby affording maximum rigidity, but also being capable of removal to enable the mesh to be rolled up for transport and storage.

Such a form of pastics mesh as has just been described lends itself to the formation of a plant training frame (e.g., a clematis panel) of appreciable size and with a sizeable mesh (e.g. 10 cm) yet capable of rolling up (after removal of the rods srom the open ended tubular filaments) into a compact roll for transport and storage, with possible flattening of the vacated tubular filaments aiding compaction.

The tubular filaments with permanently fitted rods may be formed by plastics coated rods with with the plastics coating bonded thereto, while open ended tubular filaments may be formed by plastics tubes (preferably of an internal diameter affording an easy sliding fit of further rods of the same diameter as the plastics coated ones), with the plastics coatings united to the plastics tubes by weld ing (induction or sonic) or by adhesive including solvent cement).

A number of embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a fragmentary perspective view of one form of plastics mesh in accordance with the invention; Figure 2 is a side elevation of a length of mesh as in Figure 1 partially rolled up; Figures 3 and 4 are perspective views illustrating a use of modified forms of mesh generally similar to that of Figures 1 and 2; Figure 5 is a fragmentary perspective view of another form of plastics mesh in accordance with the invention; Figure 6 is a side elevation of a length of mesh as in Figure 5 rolled up; Figures 7 and 8 are fragmentary elevations illustrating a use of modified forms of mesh generally similar to that of Figures 5 and 6; Figure 9 is a fragmentary perspective view of a further form of plastics mesh in accordance with the invention; and Figure 10 is a fragmentary section on the line 10-10 of Figure 9.

In Figure 1 a plastics mesh 1 comprises two series of parallel plastics filaments 2, 3 respectively perpendicular to each other and united at their intersections 4, as by welding (induction of sonic) or by adhesive (including solvent cement), with all of the filaments 2 being tubular and permanently fitted with rigid rods 5. The absence of rods from the plastics filaments 3 enables those filaments to bend to allow the mesh 1 to be rolled up (as shown by Figure 2) for transport and storage, while the rods 5 in the tubular filaments 2 affords the mesh some rigidity when in the flat condition.

The absence of rods from the filaments 3 also enables those filaments to bend to allow the mesh 1 to be formed into a cylindrical fencing enclosure 6 (Figure 3) or 7 (Figure 4).

for use round trees, bushes or shrubs (not shown), especially young ones. End filaments 2 are secured together, as indicated at 8, by clips, wire twists, or adhesive tape. The rods 5 project from the lower ends of the tubular filaments 2, to enable the rods to be pushed into the ground, and in Figure 4 the upper ends of the tubular filaments are joined by linked semicircular loops 9 of plastics material with spigots (not visible) fitting into and secured by welding or by adhesive) to the tubular filaments.

In Figure 5 a plastics mesh 11 comprises two series of parallel tubular plastics filaments 12. 13 respectively perpendicular to each other and united at their intersections 14 (as by welding or by adhesive), with all of the tubular filaments 12 fitted permanently with rigid rods 15, and with all of the tubular filaments 13 open ended, so as to enable further rods 16 to be inserted perpendicularly to the permanently fitted rods 15 when the mesh 11 is in the flat condition, and thereby afford the mesh maximum rigidity, but also be capable of removal to enable the mesh 11 to be rolled up (as shown in Figure 6) for transport and storage, with flattening of the vacated tubular filaments 13 aiding compaction.

With the rods 16 inserted the mesh 11 lends itself to the formation of a plant training frame (not shown), such as a clematis panel, of appreciable size with, say 10 cm. mesh size. Alternatively, the mesh 11 may be used as edge fencing 17 (Figure 7) or 18 (Figure 8) around flower beds or lawns, or along the sides of pathways, in which case the rods 15 project from the lower ends of the filaments 12, to enable the rods 15 to be pushed into the ground, and in Figure 8 the upper ends of the filaments 12 are joined by linked semi-circular loops 19 of plastics material with spigots (not visible) fitting into and secured (by welding or by adhesive) to the filaments 12.

The mesh 1 or 11 may be used for forming fencing by securing to posts (not shown) at the usual intervals (e.g. 2 metres) for plastics mesh or plastics coated wire mesh fencing.

The tubular filaments 2, 12 with permanently fitted rods 5, 15 may be formed by plastic coated rods (or wires) with the plastics coating bonded thereto, while the open ended tubular filaments 13 are preferably formed by plastics tubes of an internal diameter affording an easy sliding fit of the further rods 16.

In Figures 9 and 10 a plastics mesh 21 comprises two series of parallel tubular plastics filaments 22, 23 perpendicular to each other and united at their intersections 24 (by welding or by adhesive), with the filaments 22 permanently fitted with rigid rods 25 and with the filaments 23 open ended, so as to enable further rods 26 to be inserted perpendicularly to the permanently fitted rods 25 when the mesh is in the flat condition and thereby afford the mesh the maximum rigidity. The filaments 22 are provided with treads 27 to make the mesh 21 particularly suitable for use as a mat or duckboard to support personnel or vehicles over swampy ground.

A plastics mesh comprising two series of parallel plastics filaments perpendicular to each other and united at their intersections, with all the filaments in one of the series being tubular and permanently fitted with rigid rods, and with the filaments in the other series being solid plastics and/or tubular plastics with open ends adapted to receive rigid rods when the mesh is in the flat condition.
