DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material locking device used for attaching a peripheral portion of a sheet material to a tubular body.

[0002]

2. Description of the Related Art In soil cultivation for cultivating crops along ridges formed on the ground surface of a cultivation site, a large amount of work is carried out in a squatting posture or a crouching posture, so that the physical burden on the worker is large.
In order to cope with such a problem, a so-called elevated cultivation method has been developed as a cultivation technique for cultivating agricultural crops while holding cultivated soil at a position higher than the ground surface.

[0003] As one of the apparatuses used for such an elevated cultivation method, there is an elevated cultivation apparatus 99 as shown in FIG. This elevated cultivation apparatus includes a sheet material 93 in which a plurality of support holes 92 into which a cultivation container 91 can be fitted are formed on a support frame 90 formed by combining tubular bodies 90a on the ground surface of a cultivation area. Is stretched, and a peripheral portion 93a of the sheet material 93 is provided.
Is abutted on the outer periphery of the tubular body 90a and is locked to the tubular body 90a by the sheet material locking tool 94.

The sheet material locking member 94 has a shape in which an axial cutout 94a is formed in a part of the peripheral wall of the elastic tubular body, and the tubular body 90a is held in the elastic tubular body by passing through the cutout 94a. Therefore, the peripheral portion 93a of the sheet material 93 contacting the outer periphery of the tubular body 90a can be
The sheet material 93 is fixed on the support frame 90 by being held together. The support holes 9 of the sheet material 93
The crop 96 can be cultivated with the cultivation soil 95 by fitting and holding each of the cultivation containers 91 filled with the cultivation soil 95 in 2.

[0005]

In the elevated cultivation apparatus 99 shown in FIG. 7, during the cultivation period, the sheet material 93 swings up and down or vibrates under the influence of wind, and the sheet material 93 expands and contracts due to a temperature change. As a result, the sheet material locking tool 94 idles around the tubular body 90a and shifts from its original position, and the peripheral portion 93a of the sheet material 93 abutting on the outer periphery of the tubular body 90a is The sheet material 93 may be loosened from the sheet material 90a.

When such a situation occurs, the sheet material 9
The cultivation container 91 fitted in the third support hole 92 cannot be held in a correct posture, which may not only hinder the subsequent cultivation activity but also cause the elevated cultivation apparatus 99 to collapse.

An object to be solved by the present invention is to provide a sheet material locking device capable of securely locking a sheet material so as not to be displaced or detached from a tubular body due to shaking or vibration of the sheet material. To provide.

[0008]

In order to solve the above-mentioned problems, a sheet material locking device according to the present invention is provided with a sheet material locking device for locking a peripheral portion of a sheet material abutted on the outer periphery of a tubular body. A locking tool body having an axial cutout in a part of a peripheral wall of an elastic tubular body, and a part of the locking tool body extending or attached to the locking tool body. Rotation stopping means is provided for preventing the stopper body from idling around the tubular body by contacting the sheet member.

With such a configuration, the rotation-stopping means comes into contact with the sheet material to prevent idling of the main body of the locking member simply by mounting the same as the conventional locking member for the sheet member. During the cultivation period, even if the sheet material swings up and down under the influence of the wind, vibrates, or expands and contracts due to temperature changes, the peripheral edge of the sheet material is displaced or detached from the tubular body. And no more.

[0010] By providing a stopper as the rotation stopping means, at least a part of the locking body is protruded from the edge of the notch so that a part of the stopper comes into contact with the sheet material. As a result, idling of the locking member main body is prevented, so that detachment of the peripheral portion of the sheet material from the tubular body and loosening of the sheet material can be effectively prevented.

[0011] As the rotation stopping means, a stopper member is provided on the outer periphery of the locking member main body and a part of the stopper member protrudes from the periphery of the notch portion, so that a part of the stopper member comes into contact with the sheet material. Since the idling of the locking member main body is prevented, detachment of the sheet material peripheral portion from the tubular body and relaxation of the sheet material can be effectively prevented.

By making it possible to change the length of the stopper member protruding from the edge of the notch of the locking member body, the stopper member can be set to a length suitable for the distance to the sheet material. Therefore, it is possible to perform optimal setting for cultivation conditions, and it is possible to further improve the sheet material locking function.

[0013] By making the stopper member detachable from the locking member main body, it is possible to select a stopper member suitable for use conditions or to replace the stopper member during the cultivation period, thereby improving convenience.
