This invention exists in the proposal of the connection method of the plant protection material which consists of a base member and an upper member.

The present invention is a resinous plant protection material comprising a base member and an upper member for protecting a plant from a stepping pressure of a person or a vehicle, wherein the base member is a plurality of protrusions connected by ribs. And a base permeation part surrounded by the foundation treading pressure part and a connection part for connecting to each other, and the upper member is composed of a plurality of upper treading pressure parts and upper permeation parts connected by ribs. A string-like ring is provided on the side of one of the members, and a string-hanging part protruding from the side of another member is provided. Both members can be connected vertically by hanging the string-like ring on the string-hanging part. This is a resinous plant protection material comprising a basic member and an upper member. In order to firmly connect the base member and the upper member, the problem has been solved by providing a string-like ring and a string hook.

The present invention is a resinous plant protection material composed of a base member and an upper member, provided with a string-like ring on the side of the upper member or the base member, and protruding the ring to the side of the base member or the upper member. The following effects are obtained because the two members are connected to each other up and down by being hooked on the string hanging portion. (1) The connection between the two members is maintained unless a force that breaks the string is applied. (2) If the connection between the foundation members is released, the connection between the foundation member and the upper member can be easily released.

It is a conceptual diagram which shows the protective material which consists of the conventional base member and the conventional upper member 2. FIG.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view and a cross-sectional view of an upper member 1 constituting the plant protection material. The conventional upper member 1 of this example is shown in FIG. 6 together with the base member.
As shown in the figure, the upper member 1 is provided with a string-like ring at the end of the tube portion of the conventional upper member 1 in which ring-shaped thin tubes are connected by ribs.
In this figure, the string-like ring is provided at the end of the ring-shaped thin tube, but it may be provided on the rib. A string-like ring may be provided at an appropriate position in consideration of the positional relationship between the upper member 1 and the base member.

FIG. 2 is a plan view and a cross-sectional view of a base member constituting the plant protection material.
The base member is basically the same as the conventional one. As shown in the drawing, the foundation member is a foundation treading pressure portion that supports treading pressure from a person or a vehicle and is connected by a rib. In the figure, a base for supporting the upper member 1 is provided on the top shoulder portion of the basic treading pressure portion. The space surrounded by the foundation treading section is a place where soil is filled with the foundation permeation section and plants such as lawns are cultivated, and at the same time rainwater penetrates underground.
A connecting portion for connecting the base member vertically and horizontally to a plane is provided at the end of the base member. In this example, a male joint is provided on the side to be in contact with each other, and a female joint is provided on the other side to be in contact with the side. In this example, the joint portion also serves as the string hook portion.

FIG. 3 shows an example in which the upper member 1 and the base member shown in FIGS. 1 and 2 are used in combination.
As shown in the figure, the string-like ring provided at the end of the thin cylindrical ring connected by the rib of the upper member 1 is attracted to the connection part of the foundation member. In the drawing, a groove is not provided in the connecting portion of the base member so as to easily hook a string-like ring, but it may be provided as necessary. Since the upper member is made of resin, this string-like ring is very flexible and can be easily hooked to the connecting portion of the base member. In addition, although the connection part for the connection of a base member simple was utilized as a string hook part in this example, you may provide the place where a string-like ring | hook is hooked as a string hook part separately.

FIG. 4 is a plan view and a cross-sectional view of the upper member 2 constituting the plant protection material. In addition, the example of the conventional upper member 2 of this example is shown in FIG. 7 with the base member.
As shown in the drawing, a string-like ring is provided at the end of the bag-like cylinder connected by the rib of the upper member 2.
In this figure, a string-like ring is provided at the end of the bag-like cylinder, but it may be provided on a rib. Similar to the upper member 1 of the first example, a string-like ring may be provided at an appropriate position in consideration of the positional relationship between the upper member and the base member.

FIG. 5 shows an example in which the upper member 2 and the base member shown in FIGS. 4 and 2 are used in combination.
As shown in the figure, a state in which a string-like ring provided at an end of a bag-like tube portion constituting the upper member 2 is attracted to a connecting portion of the base member is shown. In the drawing, a groove is not provided in the connecting portion of the base member so as to easily hook a string-like ring, but it may be provided as necessary. Since the upper member 2 is made of resin, this string-like ring is rich in flexibility and can be easily hooked to the connecting portion of the base member. In addition, although the connection part for the connection of a base member simple was utilized as a string hook part also in this example, you may provide the place where a string-like ring | hook is hooked as a string hook part separately.

In the above example, the string-like ring is provided on the upper member and the string-hanging portion is provided on the base member. What is necessary is just to provide a string-like ring | wheel in the side surface rib of a base member, and to make a string hook part protrude from the rib of an upper member.
Since the base member and the upper member are paired with the string-like ring and the string hook portion, the upper and lower connections can be easily released by releasing the connection of the base member.

In the present plant protection material, it is preferable that at least a part of the position of the upper water-permeable portion and the basic water-permeable portion is formed so as to penetrate vertically so that rainwater or the like is supplied to plants such as turf. As the plant protection material, a thermoplastic resin such as polyolefin is generally used.

This plant protection material is used for general lawn protection, but it can be optimally used for schoolyard greening.
