[Industrial applications]

 The invention of the present application is a plate body made of plastics which has a simple structure and can be arbitrarily changed in shape at the boundary between the edge of a lawn planted in a park or garden and other curbs, paving stones, garden stones or sand. By embedding a lawn, the lawn can be prevented from growing beyond the boundary, and the edge of the lawn partitioned by the plate can be easily mowed with an ordinary lawn mower. Regarding the board.

[Prior art]

 Conventionally, a lawn that is generally planted in a garden or the like exhibits a growth condition as shown in FIG. 5, for example. In other words, the lawns planted in gardens and parks generally have a variety of species called Kourai turf, but this type of lawn extends laterally within a few centimeters below the surface of the ground, extending the stems in all directions and lowering the roots. Is growing significantly. Then, according to the growth of grass, new shoots and leaves grow, and it becomes necessary to manage lawn cutting at least once a week. In addition, the grass that has grown laterally hits the garden stone 06, the planting 07, the paving stone 08, etc. as shown in the figure, and especially in this part, the lawn 03 around the garden stone, the grass 04 near the planting, and the grass 05 near the paving stone are densely populated. Will be done.

It is extremely difficult to care for a lawn in such a state with an ordinary lawnmower. In other words, with a normal lawn mower, for example, the lawn 03 around the garden stone and the lawn 04 near the planting cannot be cut well, and if the lawn 05 near the paving stone is mowed with the ordinary lawn mower, the blade of the lawn mower is cut. May hit the surface or corner of the paving stone and damage the lawn mower itself.

Further, even if only such a special portion is mowed by using a special instrument such as a “hair clipper” or “scissors”, it takes a lot of work and the blade of the instrument is damaged. It is inevitable. Conventionally, a method of embedding bricks, concrete blocks, etc. in the edge of such a lawn to prevent grass from approaching planting or garden stones has also been adopted. It is extremely difficult to easily care for dense grass when it comes to blocks and bricks.

[Problems to be solved by the device]

 The invention of the present application eliminates such drawbacks and partitions the boundary of the lawn using a device having an extremely simple structure and easy to construct, thereby preventing the lawn from growing beyond the boundary. Moreover, it is an object of the present invention to provide a lawn boundary plate that allows the dense grass in the boundary area to be easily maintained using a conventional lawn mower.

[0006]

[Means for Solving the Problems]

 An elongated plastic plate having a cross-section fishing type plastic plate body composed of a vertical wall having a height of 50 mm to 100 mm and a horizontal wall having a width of 30 mm to 70 mm extending horizontally from the upper end of the vertical wall. The lawn boundary plate is characterized in that it has incisions over the entire width of its lateral wall at intervals of 50 mm to 200 mm.

[0007]

[Embodiment]

 FIG. 1 is an external perspective view of a lawn boundary plate according to the present invention. The lawn boundary plate 11 is made of a plastic plate having a total thickness of about 2 mm to 5 mm, and is a long body made by injection molding or the like. The boundary plate 11 is basically composed of an elongated body having a vertical wall portion 12 and a horizontal wall portion 13 and having a Γ-shaped cross section. The horizontal wall portion 13 is provided with slits 14 at appropriate intervals.

[0008]

【Example】

 In the embodiment of FIG. 1, the height of the vertical wall 12 is 100 mm, but generally, this height is arbitrarily set within the range of about 50 mm to 100 mm. The width of the lateral wall 13 is set to 30 mm, but a width of 30 mm to 70 mm is generally sufficient. Further, the lateral walls 13 are provided with slits 14 at substantially equal intervals, for example, 100 mm intervals. However, this slit interval is freely set, and if necessary, it is possible to additionally provide slits at appropriate places using scissors or the like when constructing the boundary plate.

Here, the relationship between the action of the lawn boundary plate 11 of the embodiment and the size of each part of the plate will be described. In general, Kourai turf, which is used for lawns in parks and the like, grows extremely fast in the direction of lateral expansion. It is known that in that state, the turf shoot grows in the basement very close to the surface of the earth, and the root of each stalk is grown and grown.

It has also been confirmed that the growth of turf shoots that grow underground can be easily prevented by embedding obstacles up to about 50 mm from the ground surface. Furthermore, it has been confirmed that this bud has a limit of about 30 mm in order to overcome obstacles on the ground surface because of the property of growing while rooting at each node of the stem.

For this reason, in the lawn boundary plate of the present invention, it is sufficient if the vertical wall is buried in the ground by about 50 mm or more, and if the lateral wall portion is 30 mm or more, the turf shoots once against the vertical wall. Then, it is forced to climb over the lateral wall by 30 mm or more, and the growth direction is naturally changed to easily prevent the crossing of the border.

FIG. 1B shows a state in which the lawn boundary plate 11 according to the present invention is curved. As shown in the figure, in the curved portions 15 and 16 of the lawn boundary plate 11, it is obvious that the vertical wall 12 can be freely curved, but it is generally difficult to bend the lateral wall 13 portion. .

Therefore, as described above, the slits 14 are formed in the lateral wall 13 portion at appropriate intervals. By doing so, for example, in the curved portion 15, the end portion of the slit 14 is opened. On the other hand, in the curved portion 16, at the end of the slit 14, the ends of the left and right lateral walls 13 are overlapped with each other so that they can be easily bent. In this way, particularly in a curved portion having a small radius of curvature, it is possible to easily cope with this by additionally providing the slits 14 at the necessary portions of the lateral wall 13 when the lawn boundary plate 11 is constructed.

FIG. 2 symbolically shows a lawn boundary plate 11 according to the present invention and a lawn area 01 to which it is applied. In this state, the lawn boundary plate 11 is embedded or pushed into the lawn ground 01 to bury the vertical wall 12 portion in the ground. It is important to embed the upper surface of the lateral wall 13 of the lawn boundary plate 11 so that the upper surface of the lawn 01 is located at the upper end of the lawn to be originally mowed.

FIG. 3 shows the outline of a state where the lawn boundary plate 11 according to the present invention is installed in a part of a garden. In FIG. 3, the lawn 02 has a lawn boundary plate 11 embedded in its boundary portion so as not to approach or intersect with the garden stone 06, the planting 07, or the sandy land 09 surrounding them. Therefore, the side wall 13 of the lawn boundary plate 11 can be seen in the boundary area between the sand 09 and the lawn 02 as shown in the figure, but in reality, the width of the side wall 13 is about 30 mm to 50 mm, so that the landscape of the garden can be seen. It's not an obstacle.

In this figure, grass is densely grown on the lateral wall 13 of the lawn boundary plate 11, and a state in which lawn mowing is required is particularly expressed. That is, in this state, the lawn 02 including the grass 05 portion near the paving stones is maintained by a conventional lawn mower. At this time, since the upper surface of the lateral wall 13 of the lawn boundary plate 11 is adjusted to the length of the lawn that should be originally trimmed, the lawn mower is trimmed while moving the upper surface of the lateral wall 13 as well as the entire area of the lawn 02. Of.

In this case, even if the blade of the lawn mower comes into contact with the lateral wall 13 portion, since the lawn boundary plate 11 itself is made of plastic, it does not damage the blade. Since the upper surface of the lateral wall 13 is flat and located at the original cutting height, it is rare that the blade of the lawn mower contacts the lateral wall 13 of the lawn boundary plate 11.

FIG. 4 shows a state where the lawn in a situation similar to that of FIG. 3 is mowed by an ordinary lawnmower. Thus, by using the lawn boundary plate 11 according to the present invention, the boundary area of the lawn can be beautifully and easily determined, and the blade of the lawn mower can be easily and easily damaged by using a conventional lawn mower. You can maintain it without doing it.

[0019]

[Effect of device]

 The lawn boundary plate according to the present invention has an extremely simple structure, and by only burying or placing the vertical wall portion at the boundary of the lawn at an arbitrary depth, it is possible to prevent the lawn from growing and spreading sufficiently. By using a simple lawn mower that has been commonly used in the past, the boundary with rocks or paving stones can be easily maintained without damaging the blade. Therefore, in combination with the structure of the lawn boundary plate, it is possible to maintain a beautifully maintained lawn and garden.
