するために用いる止め具に関するものである。[Detailed description of the invention] This invention is a method of installing sod and seed-sprayed pine for the purpose of greening land. This relates to a stopper used to prevent pine trees from peeling off, scouring, and withering.

だけになり、不安定であつた。 Conventional fasteners of this type include anchors made by bending the upper part of a metal rod at a nearly right angle, anchors with a flat plate cut to form a hook on the head, and anchors made by splitting Moso bamboo diametrically and using the knots inside to create a hook. Mekushi made into parts are known. However, although the former is durable, it is heavy because it is made of solid metal, making it inconvenient to carry when used in large quantities, and the cost of materials is high. In addition, in the case of the latter, if the hook formed by carving the board is straight-grained, or if the joint is thin and weak, there is a risk that the hook will easily break off. Moreover, processing takes a lot of time and labor costs are high. Since both had a single hook, there was only one presser surface, making them unstable.

本考案は上記の点に鑑みて提供するもので、そ
の構成は、先端が尖鋭に形成された中空棒体の上
部に複数の短い鉤棒が該棒体の軸線に対して鋭角
且つ放射状に設けられていることを要旨とする。 The present invention has been proposed in view of the above points, and has a structure in which a plurality of short hooked rods are provided radially at an acute angle with respect to the axis of the rod at the top of a hollow rod with a sharp tip. The main point is what is being said.

以下本考案の実施例を図面について説明する。
棒体１は先細テーパ状または直線状を成す５〜15
mm程度の細径の中空体から成り、先端を鋭く尖が

The rod body 1 has a tapered shape or a straight shape.
It consists of a hollow body with a small diameter of about mm, the tip is sharply pointed, and a knot 11 is formed at the upper part.

鉤棒２は棒体１の軸線に対する角度θが10〜45

端に形成した割溝を示す。 The hook rod 2 has an angle θ of 10 to 45 with respect to the axis of the rod 1.
It forms an acute angle of approximately 0.5 to 1.5 cm in diameter and 2 to 3 cm in length, and at the node 11 at the top of the rod, two or more bases converge and become one, and the tip 21 As shown in Figures 1 and 2 and Figures 4 and 5, they form bifurcated or trifurcated shapes and spread radially. It is desirable that each hook bar tip 21 be sharply pointed. Note that the base of the hook rod is located at a portion slightly lower than the top end 12 of the rod body 1. In the figure, numeral 3 indicates a split groove formed at the tip of the rod in order to expand when the rod 1 is driven into the soil to prevent it from falling out.

本考案は以上の構成であるから、地表面に芝ま

る。 Since the present invention has the above-described structure, when the grass or seed pine is placed on the ground surface and the stopper of the present invention is inserted or driven, the hook rod 2 comes into contact with the grass or seed pine and further diagonally moves. Immerse yourself. Therefore, the grass and seed pine are held down as if they were supported by three or more points, so they are prevented from peeling off or being washed away by wind and rain, and are stably fixed.

そして本考案は棒体１の頭部から２本以上の鉤
棒２が放射状に設けられている構成であるから、
用途に応じて第１〜３図のように比較的細径のマ

且つ堅牢に成形すること可能で、この種の止め具
として極めて実用的である。 Since the present invention has a structure in which two or more hook rods 2 are provided radially from the head of the rod 1,
Depending on the purpose, as shown in Figures 1 to 3, by using natural bamboo such as Madake or Hachiku with a relatively small diameter, thin branches can be easily and inexpensively made using garden shears. Moreover, as shown in FIGS. 4 to 7, it can be molded from a synthetic resin material into a shape imitating the bamboo, and can be molded to be lightweight and robust, making it extremely practical as this type of fastener.
