Description

The present invention relates to a frame for a weed-proof sheet for stretching a sheet for suppressing the growth of weeds and the like on the ground.

Weed control sheets may be laid to prevent weeds from growing in vacant lots and uncultivated fields. The weed-proof sheet is covered with a vinyl sheet on the ground, and the anchor pin is embedded in the ground to prevent it from flying. In some cases, a vinyl sheet is put on the frame material and placed on the ground.

As described in Patent Document 1, the weed-proof sheet is sufficiently pressed, the weed-proof sheet is not damaged, there is no room for grass to grow, and the slope can promote the use of thinned wood. The invention of a weed-proof structure using a wooden frame is also disclosed.

Japanese Unexamined Patent Publication No. 2001-069862

However, the weed-proof structure described in Patent Document 1 has a holding frame in which a filling member using thinned wood is spread in each of the grid-like compartment spaces composed of vertical and horizontal members on the upper surface of the weed-proof sheet. It is to be placed, and it is necessary to put a weed-proof sheet on a flat ground in advance.

If the weed-proof sheet is stretched on the frame material in advance, it can be installed simply by placing it on the ground, but if the ground is uneven, it may float from the ground as a whole or the frame material may tilt. It is not possible to cover the weed-proof sheet in a well-balanced manner.

Therefore, an object of the present invention is to provide a frame for a weed-proof sheet that can be installed narrowly between the weed-proof sheet and the ground even if the ground is uneven.

In order to solve the above problems, in the frame for a weed-proof sheet of the present invention, a plurality of vertical pipes and horizontal pipes are connected by joints to be connected in a ring shape, and a plurality of intervening pipes are provided between the vertical pipes at both ends. A frame material having a plurality of support pipes arranged intermittently so as to be lined up in the same direction and further extending downward from an arbitrary position of the vertical pipe, the horizontal pipe, and the intermediate pipe so as to be adjustable in length, and the vertical pipe or the vertical pipe or A plurality of sheets for stretching in each space formed by the inter-pipe and the horizontal pipe, and a fastener for fastening the sheet to the vertical pipe or the inter-pipe are provided, and each of the sheets is on the ground. It has a width that covers the vertical pipe or the inter-pipe on both sides so as to absorb the difference in unevenness, and is fixed to the vertical pipe or the inter-pipe by the fastener in a state where the ends are overlapped with other adjacent sheets. The support pipe is characterized in that the space between the frame member and the ground is narrowed, and the depths of the support pipes are adjusted to be uniform when they are pierced into the ground.

According to the present invention, the frame material stretched with the weed-proof sheet can be installed narrowly between the weed-proof sheet and the ground. Even if the ground is uneven, the weed-proof sheet can be covered in a well-balanced manner without floating from the ground or tilting the frame material.

When the weed-proof sheet is placed directly on the ground, a through hole is made in the weed-proof sheet and fixed to the ground, and the tear of the weed-proof sheet may spread from the through hole. Since it covers the ground without being used, the durability of the weed-proof sheet can be maintained.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Those having the same function may be designated by the same reference numerals, and the repeated description thereof may be omitted.

First, the structure of the frame for the weed-proof sheet according to the present invention will be described. FIG. 1 is a plan view showing a frame for a weed-proof sheet. FIG. 2 is a bottom view showing a frame material of a frame for a weed-proof sheet. FIG. 3 is a plan view showing a state in which the sheet of the weed-proof sheet frame is partially peeled off. FIG. 4 is a front view showing a state in which the weed-proof sheet frame is installed on the ground. FIG. 5 is a photograph showing a state in which the frame for the weed-proof sheet is not installed. FIG. 6 is a photograph showing a state in which only the frame material of the frame for the weed-proof sheet is placed. FIG. 7 is a photograph showing a state in which a frame for a weed-proof sheet is installed.

As shown in FIG. 1, the weed-proof sheet frame 100 is a frame material 200 covered with a weed-proof sheet 300 that covers a predetermined area of the ground 110. The ground 110 is a vacant lot, an uncultivated field, or the like, and is not limited to flat land and may have large irregularities. In addition, because it suppresses the growth of weeds, it is mainly composed of soil, and even if it is filled with stones, it is not paved with asphalt or concrete.

As shown in FIG. 2, the frame material 200 is a frame made of a metal pipe such as iron to stretch the sheet 300. A plurality of vertical pipes 210 and horizontal pipes 220 are connected by a joint 250 to be connected in an annular shape, and a plurality of intervening pipes 230 are intermittently arranged between the vertical pipes 210 at both ends so as to line up in the same direction. It has a plurality of support pipes 240 extending downward from arbitrary positions of the horizontal pipe 220 and the inter-pipe 230 so as to be adjustable in length.

As shown in FIG. 3, the sheet 300 is a vertical pipe 210 or a vinyl sheet to be stretched in each space 260 formed by the inter-pipe 230 and the horizontal pipe 220. A fastener 400 is used to fasten the sheet 300 to the vertical pipe 210 or the inter-pipe 230.

The sheet 300 has a width that covers the vertical pipes 210 or the interstitial pipes 230 on both sides, and in a state where the right end of one sheet 300a and the left end of the other sheet 300b adjacent to the sheet 300 are overlapped with each other, the vertical pipes 210 or the interstitial pipes 210 or the interstitial pipes 400 are used. It is fixed to the pipe 230.

As shown in FIG. 4, when the frame member 200 is placed on the ground 110, the support pipe 240 is pierced into the ground 110 so that the space between the frame member 200 and the ground 110 is narrowed. Since the sheet 300 is stretched every 260 spaces and is flexible against expansion and contraction, even if there is a protruding portion on the ground 110, it can be received and the difference in unevenness of the ground 110 can be absorbed. ..

The length of each support pipe 240 can be adjusted, and the depth to the ground 110 may be adjusted to be uniform. If a hard object such as a stone is buried and the support pipe 240 cannot be pierced, a short object may be used.

As shown in FIG. 5, when the weed control sheet frame 100 is not installed, weeds grow on the ground 110, and weeding is performed as necessary. Weeding by hand or using a machine is laborious and costly.

As shown in FIG. 6, the frame material 200 is assembled so that the area to be weed-proof can be covered. The vertical pipe 210 or the horizontal pipe 220 may be inclined at an angle, but it is preferable to arrange the intervening pipes 230 so as to be arranged in parallel and at regular intervals.

Regarding the horizontal pipe 220, a joint 250 may be provided at each position where the inter-pipe 230 is arranged. Further, with respect to the vertical pipe 210 and the inter-pipe 230, the joint 250 may be provided at each position where the support pipe 240 is arranged. The outer shape of the joint 250 may be freely changed by using, for example, a universal joint (universal joint).

As shown in FIG. 7, by stretching the sheet 300 on each space 260 of the assembled frame material 200 and fixing it with the fastener 400, weeds grow on the ground 110 without fixing the sheet 300 itself to the ground 110. It can be covered so that it does not exist. Since the sheet 300 is fixed to the frame member 200, it is not blown away, and the support pipe 240 is only shallowly stuck in the ground 110 and can be easily removed.

The fastener 400 is made of plastic or metal, for example, a C-shaped spring material or a lock type that can be easily attached and detached, and the ends of adjacent sheets 300a and 300b are overlapped with each other. Then, it may be fastened so as to be sandwiched between the vertical pipe 210 or the inter-pipe 230. A plurality of small ones may be provided intermittently, or one long one may be provided.

According to the present invention, the frame material stretched with the weed-proof sheet can be installed narrowly between the weed-proof sheet and the ground. Even if the ground is uneven, the weed-proof sheet can be covered in a well-balanced manner without floating from the ground or tilting the frame material.

When the weed-proof sheet is placed directly on the ground, a through hole is made in the weed-proof sheet and fixed to the ground, and the tear of the weed-proof sheet may spread from the through hole. Since it covers the ground without being used, the durability of the weed-proof sheet can be maintained.

Examples of the present invention have been described above, but the present invention is not limited thereto. For example, a grid-like frame material may be used through the pipe so as to intersect the inter-pipe. Further, the support pipe may be simply placed on the ground after adjusting the length without piercing the ground. Further, the fastener may be a fastener that is sandwiched from above and below and fastened.
