Abstract

A chain link woven mesh comprises successive undulated transverse links (1,2,3,4), which are interconnected together at the bent portions of the links, whereby each pair of successive undulated links (1,2), (3,4) forms a row of adjacent rectangular or square meshes (5) with four sides. At least at one border of the mesh, for each pair of successive links, the last side of the first link (1) is bent upwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the second link (2). The last side of the second link (2) is bent downwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the first link (1). The advantage is that a very strong border is obtained.

Description

There is the chain link woven mesh of binode

Technical field

The present invention relates to a kind of chain link woven mesh, it comprises continuous wavy or in a zigzag horizontal chain link, these chain links interconnect in the bend office of chain link, thus each adjacent rectangle or square mesh that continuous wavy chain link has been formed a row and had four edges.

Background technology

Above-mentioned chain link woven mesh is normally known, and for example in United States Patent (USP) 3473652,3512760 and European patent 862959B1, describes.

This known chain link woven mesh is typically provided with the unijunction of standard in two edge or edge.The unijunction of standard is that the end by making every pair of continuous chain link hooks to make or obtain mutually.

The shortcoming that is provided with this known chain link woven mesh of standard unijunction is: the unijunction of these standards is not by mode closure firmly, or opens under quite low tension force effect.For this known mesh grid, the successful use in many special circumstances is an actual problem for this.

This problem that chain link woven mesh exists has solved by several special modes in early days, for example: by the two ends strand of every pair of continuous chain link or steel wire is twisted with the fingers several times and mutually twisted with the fingers together; By the two ends of every pair of continuous chain link or steel wire are welded to each other together ....But all these early stage solutions of this problem co-pending have caused other new problem.

Summary of the invention

The object of the invention is to carry a kind of improved chain link woven mesh, thereby, this problem of unstable standard unijunction solved by cheap and simple mode.

Another object of the present invention is to provide a kind of chain link woven mesh, and it has at least one very firm edge or selvedge (fringing).

Chain link woven mesh according to the present invention is characterised in that, at least in an edge of mesh grid, for every pair of continuous chain link, the most end limit of the first chain link is by a bending acute angle upwards and backward, thereby the limit second from the bottom of the second chain link is hooked in the end on the most end limit of this first chain link, and the most end limit of the second chain link is by a bending acute angle downwards and backward, thereby the limit second from the bottom that the first chain link is hooked in the most end of this second chain link end on one side.

, for every group of two continuous chain links, to tie to substitute now the unijunction of a standard by two special locks according to the specific characteristic of this novel chain link woven mesh of the present invention.Owing to now tying by two special locks the unijunction that substitutes each standard, very firm edge or selvedge (fringing) are obtained.

State now, according in several special applications of this mesh grid of the present invention, described two special locks knot is very firm, or described two special knots have very high resistance jointly, to prevent that edge is opened in the use of harsh condition of work or mesh grid.

Accompanying drawing explanation

From the more detailed description providing by example referring to accompanying drawing, will fully understand other objects of the present invention and advantage, wherein:

Fig. 1 shown according to the top view of a part for chain link woven mesh of the present invention,

Fig. 2 has shown according to the details drawing of four lock knots of the present invention.

The specific embodiment

Fig. 1 shown in normal deployed condition according to the top view of a part for chain link woven mesh of the present invention.This mesh grid comprises continuous wavy or in a zigzag horizontal chain link 1,2; 3,4; ..., they interconnect or interweave in the bend office of chain link.Each to continuous wavy chain link 1,2; 3,4; ... form a row and had adjacent rectangle or the square mesh 5 of four edges.The straight flange of mesh 5 between sweep can be corrugated.Each chain link 1,2,3,4... be for example by the rod iron around thering is substantial rectangular cross section spirally winding steel wire form.This means that steel wire has been bent to flexuose pattern.Each chain link or steel wire penetrate in the zigzag steel wire chain link that previous string is good across the width of mesh grid.Steel wire or chain link can suitably apply corrosion-resistant coating.The example of these nets is for example clearly having described in United States Patent (USP) 3473652 and 3512760.

Fig. 1 has shown the standard unijunction 6 at the left margin place that is positioned at mesh grid.These standard unijunctions 6 of mesh grid are by making every pair of continuous chain link or steel wire 1,2; 3,4; ... end mutually hook formed.This means, the most end limit of chain link 1 or the end on limit, edge are around most end limit or the edge spring song of chain link 2, and vice versa.

Fig. 1 has shown the twin-lock knot 7 that is positioned at the right edge of mesh grid according to of the present invention.In this case, the most end limit of the first chain link 1 or limit, edge, by a bending acute angle upwards and backward, so that the limit second from the bottom of the second chain link 2 is hooked in the end on this most end limit, thereby form the first lock knot 7 by which.In addition, the most end limit of the second chain link 2 or limit, edge are by a bending acute angle downwards and backward, thereby the end on this most end limit is hooked the limit second from the bottom of the first chain link now, for form the second lock knot 7 by which.

As seen, be arranged in formed mesh grid according to two lock knots of the present invention or twin-lock knot 7, and the unijunction of standard is positioned at the outermost part place at mesh grid edge from Fig. 1.In addition, the bending most end limit of chain link 1,2,3,4... has formed firmly position, edge or selvedge (fringing) together.

In a preferred embodiment of the present invention, two edges of mesh grid are all provided with according to twin-lock knot of the present invention.

According in another preferred embodiment of mesh grid of the present invention, the end on the most end limit of the first chain link 1 is hooked in the centre on the limit second from the bottom of the second chain link 2 substantially; And the end on the most end limit of the second chain link 2 is hooked in the centre on the limit second from the bottom of the first chain link 1 substantially.

Fig. 2 has shown the upper view of the amplification of the thin portion of Fig. 1.In Fig. 2, use the same reference numerals of Fig. 1.
