Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to horticultural water moss, aquarium aquatic plants, artificial sea reef seaweed
The present invention relates to artificial grass and leaves used for display and the like.

[Conventional technology]

The present inventor has invented an artificial grass and disclosed it in Japanese Patent Publication No. 62-8545 (Japanese Patent Laid-Open No. 60-151352).

The artificial grass leaf according to the above-mentioned prior invention disclosed by the present inventor is made by using a warp knitting machine, and the stem core continuing in the length direction is continuously changed back and forth by alternately changing the curving direction into S-shape and Z-shape. Of the knitting loop of pile yarn formed along the chain loop of the ground yarn by engaging the chain loop and the hook loop of the S-shaped stitch and the Z-shaped stitch of the ground yarn formed by Both ends are dipped into the chain loop of the following ground yarn, and the leaf axis is projected from the stem core.

[Problems to be solved by the invention]

In the above-mentioned prior invention, a knot loop of pile yarn is formed along the chain loop of the ground yarn, and both ends of the knot loop are dipped in the chain loop following the ground yarn to form the leaf axis. Since it is formed, even if you try to use a thick tape or a wide tape in which a large number of yarns are bundled in the pile yarn that constitutes the leaf axis, a knot loop that follows the chain loop of the thin ground yarn is formed in the warp knitting machine. Or, it is difficult to pull it out by submerging it in the chain loop of the thin ground thread.

Therefore, the thickness of the pile yarn to be used is limited, and it is not possible to obtain an artificial grass leaf in which a large number of leaf axes are closely projected or an artificial grass leaf in which a wide leaf axis is projected.

[Object of the Invention]

Therefore, an object of the present invention is to obtain an artificial grass and leaf which has a wide range of leaf axes and a large number of leaf axes densely projected and which can be used as seaweed for artificial fishing reefs.

[Structure of Invention]

That is, in the seaweed 19 for artificial fishing reefs according to the present invention, the ground thread 13 changes the bending direction alternately in the S shape and the Z shape, and bends the upper and lower sides of each, and the chain loop 11 with the opening facing the front is formed. S-shaped stitches 14 and Z-shaped stitches 15 are formed alternately to form hooked loops 12 having openings on the other side and the openings are directed to the side surfaces, and the alternate one chain loop 11 and the other hooked loop 11 are formed. A stem core 16 is formed by engaging 12 with each other in a chain shape in the length direction W, and at least two hook-and-loop loops 12 and 12 ′ that are arranged in front and rear in the length direction W of the stem core 16 are tape-shaped U. It is characterized in that the leaf shaft 18 is bent in the direction of left and right to pass through and protrudes from the stem core 16 in a tufted manner.

As disclosed in the above-mentioned prior invention, the stem core 16 has each hook loop 12,12 ', 12 "of stitches 14,15,14' ...
It is also possible to turn the knitting yarn 20 into zigzag in the left and right direction and dive into it (Figs. 1 and 2), and several ground yarns.
A series of stitches 14 ・ 14 ’(15 ・ 1
It is also possible to form the stem core 16 in a tape shape by 5 ') (Fig. 2).

The number of the hooked loops 12 through which the tape 17 can pass is not particularly limited as long as it is 2 or more, but the limit is generally 5 to 6,
When the number of hook loops 12 that can pass through 17 is an odd number, both ends form leaf shafts 18 and 18 'that are divided into the left and right of the stem core 16 (Figs. 1 and 2), and the number is even Will form a pair of leaf shafts 18 and 18 'on one side of the stem core 16 (Figs. 3 and 4).
Figure).

Of course, this means how to dive one tape, and when two tapes dive from the left and right of the hook loop 12, the leaf shafts 18 are formed symmetrically on the stem core 16.

1 to 4 show how the tape 17 dives,
Is an S-shaped or Z-shaped bend twice when passing through the three hook loops 12 (Figs. 1 and 2) and U when passing through the two hook loops 12 before and after. Bent once (3rd
(Fig.), W when you go through four hook loops 12 before and after
It will be bent three times (Fig. 4).

〔The invention's effect〕

In the present invention, the tape 17 does not form the leaf axis by submerging both ends of the knot loop formed along the chain loop of the ground thread into another chain loop of the ground thread, and The two hook loops 12 and 12 'are respectively passed in one direction from left to right or right to left to form a leaf shaft 18, which simply passes by the side of the knitting needle during the formation process on the warp knitting machine. Since the knitting needles are knitted simply by passing them between the chain loops of the ground yarn, there is no problem in knitting even if a wide tape is used. It is possible to obtain protruding seaweed for artificial fishing reefs, and therefore, it is possible to obtain novel seaweeds for artificial fishing reefs in which the shape of the leaf axis 10 is changed using various forms of tape.

Then, the leaf shaft 18 does not penetrate straightly through the hook loop 12 and is locked to the stem core 16, but is locked while passing through two or more hook loops 12 by changing the left-right direction. , It does not come off from the hook loop 12 during use and fall off from the stem core 16, and if the tape 17 is made thicker, it will receive a stronger binding force from the hook loop 12 so that the leaf shaft 18 is more difficult to fall off. Therefore, a durable artificial reef seaweed 19 can be obtained.
