Abstract

PURPOSE: To obtain a lawn spit for fixing a lawn mat on a vegetation ground capable of inserting it into the ground with a single hand without using a hammer. CONSTITUTION: A pushing head 16 of a lawn spit 15 is made in a flat board- shape. The pushing head 16 and one or two of sticks 17, 18 which are attached on the lower face of the pushing head and directing downward are integrally molded of a synthetic resin. Optionally, barbs 19 are formed on the stick 17. Further, a biodegradable resin which is decomposable by microorganisms in the soil may be used as the synthetic resin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in lawn skewers used for fixing lawn mats to vegetation.

[0002]

2. Description of the Related Art When turf is planted, a turf skewer is inserted from above into a rectangular turf mat having a side of about 30 cm which is generally arranged on the vegetation plant to fix the turf mat to the vegetation plant. As shown in FIG. 6, a conventional lawn skewer 20 includes a pressing plate 21 for pressing the lawn from above and a shaft rod 22 for inserting the lawn into the ground. The shaft rod 22 penetrates the central shaft hole 23 of the pressing plate 21, the tip is thin and sharp, and the head 24 has a larger diameter than the shaft hole 23. Further, although not shown, a lawn skewer in which a part of a round bamboo is used as it is and the lower part of the head is cut to form one shaft rod is also used.

On the lawn of a stadium such as a soccer field, the lawn skewers used for fixing the lawn mats are removed as soon as the lawn mats are rooted, but the lawn of the garden etc. is decomposed by microorganisms without removing the lawn skewers into soil. Had been assimilated. In the conventional lawn skewers, the pressing plate is separated from the shaft rod or the head of the shaft rod is too small to be pushed into the ground with one hand, so after inserting the lawn skewer from above the grass mat to the ground, hammer It was necessary to sunk the head of the axle together with the holding plate into the grass mat. The work of hitting the head of the shaft rod is troublesome and may damage the grass.

Japanese Unexamined Patent Publication (Kokai) No. 5-268836 proposes a lawn skewer in which the work of hitting the head of the shaft rod can be omitted. However, the lawn skewer is several tens of centimeters longer than the conventional one and is cut by a notch. It is possible, but because it does not have a holding plate, 1
There is a problem that the grass mat cannot be securely fixed unless more grass skewers are inserted into the grass mat than in the past.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the purpose thereof is to be able to sunk a turf mat without hitting it with a hammer from above. Another object of the present invention is to provide a lawn skewer capable of securely fixing a lawn mat.

[0006]

In order to achieve the above object, the means adopted by the present invention is to integrally form a flat pressing plate of a lawn skewer and a shaft rod with a synthetic resin. One shaft rod is hung from the center of the lower surface of the holding plate, or two long and short shaft rods are hung from both sides of the holding plate. Further, if necessary, a barb is formed in the lower half of the shaft rod. If the lawn skewer is not removed after the lawn mat is rooted, the synthetic resin of the lawn skewer should be biodegradable.

[0007]

The pressing plate of the lawn skewer according to the present invention has a flat plate shape, and since the pressing plate is integral with the shaft rod, the lawn skewer can be easily inserted into the planting material with one hand. When the pressing plate of the lawn skewer is pressed with one hand from above, the pressing plate sinks into the grass mat, and the shaft rod is stabbed into the vegetation material to a predetermined depth. Depending on the soil quality of the vegetation,
Use a turf skewer with one or two shafts or a turf skewer with a barb. If the lawn skewer is a biodegradable synthetic resin,
It is decomposed by microorganisms in the ground and assimilated into soil.

[0008]

EXAMPLE A lawn skewer according to the present invention will be described based on an example shown in the drawings. The lawn skewer 1 of the first embodiment shown in FIG. 1 is a synthetic resin molded product, and a holding plate 2 and one shaft rod 3 hanging down from the center of the lower surface of the holding plate are integrally formed. The holding plate 2 has a plate shape with a long side of 30 mm, a short side of 20 mm, and a thickness of 3 mm, and the shaft rod 3 has a length of 100 mm, a base diameter of 6 mm, and a tip diameter of 3.
It has a truncated cone shape of mm.

The turf skewer 5 of the second embodiment shown in FIG. 2 is a biodegradable synthetic resin molded product, and the length of the pressing plate 6 from the both end portions of the lower surface is shorter.
The shaft rods 7 and 8 of the book hang down. The holding plate 6 has a long side of 30 mm,
It has a plate shape with a short side of 12 mm and a thickness of 4 mm, and the long and short shaft rods 7 and 8 have a diameter of 6 mm. The length of the long shaft 7 is 60
~ 100mm, the length of the short shaft 8 is 30 ~ 50mm,
In each case, the tip is sharply cut. Turf skewer 5 is 2
Since it has the shafts 7 and 8 of a book, it can also be used for relatively soft vegetation.

The lawn skewer 10 of the third embodiment shown in FIG. 3 is a synthetic resin molded product, and like the one shown in FIG.
The shaft rod 12 of the book hangs down. The holding plate 11 is the same as that of FIG. 1 and the length of the shaft rod 12 is also the same as that of FIG. 1, but unlike the one of FIG. Since it is provided in a shape, it can be used for a flexible vegetation similar to that of FIG.

The turf skewer 15 of the fourth embodiment shown in FIG. 4 is a biodegradable synthetic resin molded product, and two shaft rods 17 and 18 hang down from both side end portions 16 of the lower surface of the holding plate. Since the lower half portion of the long shaft 17 is provided with barbs 19 of several stages as in the case of FIG. 3, it can be used for a vegetation material which is more flexible than those of FIGS. 2 and 3. . As shown in FIG. 5, since the pressing plate 16 and the shaft rods 17 and 18 are integrally formed in the lawn skewer 15, when the pressing plate 16 is pushed from above the turf mat 4 with one hand, the shaft rod 17 having a sharp tip is formed. , 18 are stuck in the vegetation material 9. Therefore, it is extremely easy to squeeze the pressing plate 16 into the turf mat 4 and insert the shaft rods 17 and 18 to a predetermined depth. Even if the vegetation cover 9 is flexible, the shaft bar 17 has a barb 19, so there is no risk of the turf skewer 15 coming off from the vegetation cover 15, and the turf skewer 15 securely fixes the turf mat 4 to the vegetation cover 9. can do. Since the turf skewer 15 is made of a biodegradable synthetic resin, it is eventually decomposed by microorganisms in the ground and assimilated into soil.

[0012]

The turf skewer of the present invention, unlike the conventional one, is a synthetic resin molded product in which the flat pressing plate and the shaft rod are integrated, so that the turf mat can be placed on the turf mat without hammering. It is possible to squeeze the presser plate into the grass mat and push the shaft bar deep into the vegetation mat with just one hand, so that the efficiency of turf planting work can be improved. Especially, the turf skewer with the barb attached to the shaft and the shaft bar
The turf skewer of the present invention has a special effect that the turf mat can be reliably fixed to the vegetation cloth even if the vegetation cloth is flexible, which has not been obtained by the conventional ones. Further, when the synthetic resin is biodegradable, it is decomposed by the microorganisms in the ground and disappears as in the case of the conventional natural bamboo, so that there is no possibility that it will remain on grass and cause troublesome pollution.
