Description

  The present invention relates to a knot-changeable network.

  A no knotted rhombus as shown in FIG. 12 has existed conventionally. In this type of mesh, generally, a twist is formed on each side 1′a, 1′b, 1′c, 1′d of the rhombus, and each side 1′a, 1′b, 1′c, 1 The intersection of 'd is a penetration node 2. At this time, the penetrating node does not form a spherical portion like a nodule, and therefore contributes to not damaging an object that abuts the mesh surface.

Here, a general example of forming a square mesh body having no knotted square mesh will be described. First, a cylindrical mesh 3 ′ having a rhombus mesh as shown in FIG. 13A is manufactured by a known method. Next, as shown by the slanted dot-and-dash line in the figure, the peripheral surface of the cylindrical net 3 'is cut in a direction along one side of the rhombus, and as shown by the horizontal one-dot chain line in the figure. Then, it is cut in the longitudinal direction f1 (or cut in the width direction f2) to form a cutting network 3′a as shown in FIG. B. Thereafter, this cutting network 3′a The triangular portion 3′a1 at both ends of the cut-out portion is cut out, and the cutting net portion 3′a2 remaining after the cutting is formed into a rectangular net having a square mesh.
JP 2002-105819 A

  The above Japanese Patent Application Laid-Open No. 2002-105819 is by the applicant of the present patent application and enables the problem of the prior art to be solved, but the present invention further develops it, that is, clears the problem of the prior art. In the above, it is intended to provide a variety of rectangular meshes, or a network capable of changing the mesh of a knotless network that allows the mixture thereof.

  The present invention creates a knot-shaped mesh with no knots, and has a configuration in which the knot-shaped size ratio of the upper row or the lower row is the same or different in addition to the nodal portion being a through-type node or a staggered type node. It is characterized by. At this time, the side long side dimensions of the upper and lower rows of turtle shells are appropriately made different, or one or more penetration nodes are formed between the side long sides of the turtle shell, The ratio of the shoulder side dimension to the side long side dimension is set to a ratio of 1: 1 to 3, or is set to a ratio of 1: 0.4 to 0.9.

  According to the present invention configured as described above, it is possible to use any mesh without using waste as a conventional mesh body for use as a square mesh, as well as for use as a turtle mesh network. It is possible to provide a rectangular net having a spacing and dimensions in a simple, inexpensive and efficient manner.

  Thus, according to the second aspect of the present invention, since squares having different mesh intervals and dimensional shapes can be formed in a layer at appropriate places in one mesh body, it has never been achieved. Multifunctional use can be developed.

  According to the invention described in claim 3, in addition to the above-described effects, a relatively large mesh structure can be appropriately used, and the propagation of fraying and tearing is well prevented, thereby contributing to the improvement of the service life. Become.

  In addition, according to the invention of Claim 4 and Claim 5, the implementation which is excellent in the remarkable practical use of the said effect can be achieved.

  FIG. 1 is a schematic view of a basic embodiment of a no-nodation turtle shell network according to the present invention. As shown in the figure, the basis of the present invention is a knotless mesh network 1 having no knots, and 1 ′, 1 ′, 1 ′,. “, 1”, 1 ”,... Are the lower turtle-mesh nets, and 2 is a node between each mesh that is made into a no-knot. There are clauses, but any of them may be adopted.

  In the illustrated example (FIG. 1), the shoulder side “a” and the side long side “b” are formed in the same dimension in the upper and lower rows of the turtle shell mesh, but FIG. And the side long side b are made different at a ratio of 1: 1 to 3 (in the example shown, a ratio of 1: 2).

  On the other hand, the shoulder side a and the side long side b of the turtle shell may be 1: 0.4 to 0.9 as shown in FIG. (In the example shown, the ratio is 1: 0.5)

The formation of a square mesh body from the turtle shell mesh according to the present invention obtained as described above is performed as follows. That is, to form a longitudinal f ₁ and a specific position in the width direction P1, P2 in cutting network member 3 cut to square shape as chain line suitable one point of the cylindrical knitted been turtle knitted body as shown in FIG.

And Thus, to pull the both side edges m _1, m ₂ of the width direction f ₂ of the cutting network element 3 in the width direction f _2, Katahen a of hexagonal th 1 to the width direction f ₂ of the cutting network element 3 In this state, the tension string 4 is sewn along the side edges m ₁ and m ₂ of the tension. The same well when attaching the cord 4 'is also the longitudinal direction f ₁ edge m _3, m _4, FIG. 5 shows this state.

  In the above embodiment, the shoulder side a and the side long side b are related to the turtle-mesh net having a ratio of 1: 1, but FIG. 6 is a square with the ratio of 1: 2 shown in FIG. It shows the formation of a net. In FIG. 5, the squares are rectangular, whereas in FIG. 6, a square is formed. Thus, the desired dimensional intervals and shapes of these squares can be arbitrarily obtained by appropriately changing the dimensional ratio of the shoulder side a and the side long side b.

  In each of the above-described embodiments, the turtle shells having the same size and shape are formed in the upper and lower horizontal rows, but FIG. 7 is an example in which they are appropriately changed. That is, in the figure, the s column has a 1: 1 ratio of the shoulder side a and the side long side b of the turtle shell, while the s' column has a ratio of 1: 0.5. Thus, FIG. 8 shows a square mesh formed by pulling the above-described turtle shell mesh in the width direction.

  Although the above is an example of a mixed change rectangular network, it is possible to form layers with different intervals and size shapes as appropriate in a layered manner at a necessary distance interval. This is another example in which the intervals and shapes of the squares are made different for each layer (s, s ′, s ″,...).

  FIG. 10 is a partially enlarged structural view of the shoulder side a and the side long side b of the turtle shell network in each of the above embodiments, where the shoulder side a is a twisted portion of a double yarn (u, u), The side b is formed with a twisted yarn portion formed by a combination of adjacent twin yarns (u, u, u ′, u ′).

  In the above example, the entire side long side b is formed by the twisted yarn portion of both twin yarns. However, the one shown in FIG. It is the structure of the single twine which does not twist together. By the way, in the case of forming the side long side b having a large dimensional length, it is preferable to form a plurality of penetrating nodes k at appropriate intervals in addition to the intermediate distance as in this example, or through the entire length. The penetration node k may be formed. In the case of carrying out in this way, fraying of the twisted yarn and propagation at the time of breaking can be easily stopped locally and can be used for a long period of time.

  The mesh body according to the present invention is used not only in the size and shape of the tortoise shell, but also in the cutting place as appropriate without causing any wasteful cutting waste when using the square mesh. The desired rectangular mesh can be used as appropriate by simply attaching the pull string. In addition, since the shape of the eye and the interval between the eyes can be appropriately changed within one mesh body, it can be used in a versatile and functional manner. Note that the material used for the net in the present invention is exclusively synthetic fibers (such as saran, nylon, vinylon, etc.), but may be cotton yarn, starch fiber or the like.

It is a schematic diagram of an embodiment of a network capable of changing the mesh of a knotless network according to the present invention. This is a modification of the above. Similarly, this is a modification. It is explanatory drawing which shows the example of a cutting | disconnection of a deformable net body. It is explanatory drawing which shows the mesh production of a square mesh (rectangular mesh) with the turtle shell of the said cutting net.
