Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lawn planting block in which blocks are embedded in the ground at appropriate intervals to plant lawns.

[0002]

2. Description of the Related Art A conventional lawn planting block has a large number of greening blocks 1 having a rectangular cross section, as shown in FIG.
2 were arranged vertically and horizontally in a lattice pattern. The greening block 12 has a predetermined length and is made of a concrete cast product or a plastic injection molded product. The greening block 12 is arranged by digging down the ground 11 as appropriate and vertically and horizontally opened on the ground 11 with appropriate gaps. Then, soil is piled up by the height of the greening block 12 shown by the one-dot chain line B in the figure, and lawn is planted in the portion where the soil is piled up to form a lattice pattern.

[0003]

However, since the conventional greening block 12 has a constant length or only a predetermined length, the arrangement interval is limited and the size of the lattice pattern is limited. Since it is limited, there is a problem that the degree of freedom of the arrangement pattern is small.

Further, since a large number of greening blocks 12 are individually placed on the ground 11, the positioning is unstable and easily misaligned, and the construction is troublesome.

In view of the above circumstances, the present invention is to provide a lawn planting block that enables a variety of arrangements rich in variations by using a long elongated block and that is stable in positioning and easy to construct. Has an aim.

[0006]

In order to solve the above-mentioned problems, the lawn planting block according to claim 1 is a long block having a substantially rectangular cross section and a groove formed on at least one side surface thereof. Along with installing multiple grooves facing upward,
A plurality of other long blocks are placed non-parallel on these lower long blocks with the groove facing downward, and connecting tools are respectively attached to all or part of the intersections of these lower long blocks. Are arranged, and the upper and lower portions of the connecting tool are engaged with the grooves of the upper and lower long blocks, respectively.

According to a second aspect of the present invention, a short block having a substantially rectangular cross section and an engaging portion protruding from a lower side surface is arranged in parallel on the lower long block, and the engaging portion is provided. It is characterized in that the groove is engaged with the elongated block.

A third aspect of the present invention is characterized in that minute ridges are provided along the longitudinal direction on both side surfaces in the groove in the upper and lower elongated blocks.

The operation will be described below.

According to the structure of claim 1, a plurality of long blocks are installed on the lower side, a plurality of long blocks are placed on the lower block, and the intersections are engaged with the connecting tool as appropriate. Therefore, the positioning is stable and the construction is easy. Moreover, since the upper long blocks can be arranged at arbitrary intervals on the lower long blocks, a lattice pattern of any size can be obtained. Further, since the upper long block can be arranged at an arbitrary angle with respect to the lower long block, not only the lattice pattern but also an oblique striped pattern or other more complicated arrangement pattern can be used.

According to the structure of claim 2, since the short block is placed on the lower long block and engaged by the engaging portion, the short block is provided with a gap in the longitudinal direction as in the conventional case. It can be opened and placed, and the positioning can be stabilized.

According to the third aspect of the invention, since the convex strips are provided in the grooves of the upper and lower long blocks, the convex strips facilitate the upper and lower portions of the connector and the engaging portions of the short blocks in the vertical direction. It can be engaged so as not to come off.

FIG. 2 shows a long block 1 used in the lawn planting block of this embodiment. The long block 1 is a long block having a rectangular cross-sectional shape with a width of 50 mm and a height of 40 mm. A rectangular concave groove 1a having a depth of about 15 mm and a width of about 38 mm is formed on the side surface facing upward in the drawing. Further, in order to reduce the weight and to save the material, rectangular through holes 1b, 1b which are divided into two in the width direction are formed in the main body portion below the groove 1a. Therefore, the cross-sectional shape of the long block 1 is a Chinese character “circle”. On both side surfaces of the groove 1a, minute ridges 1 are formed along the longitudinal direction at positions sufficiently high from the bottom surface.
c, 1c are provided. The long block 1 having such a shape is preferably manufactured by extrusion molding of plastic, and can have a long arbitrary length. Then, the long block 1 is manufactured to have a sufficiently long length, and is cut into an arbitrary length according to the size of a lawn planting site or the like to be actually used.

As shown in FIG. 1, a plurality of the long blocks 1 are embedded in the ground 11 in parallel with the side having the groove 1a facing upward at appropriate intervals. In addition, a plurality of other long blocks 1 having the same shape are placed on these lower long blocks 1 in parallel at appropriate intervals with the side surface having the groove 1a facing downward. FIG. 1 shows a case where these upper long blocks 1 are arranged orthogonally to the lower long blocks 1. Although the same molded products are used as the upper and lower elongated blocks 1 and 1, it is also possible to use those having different sectional shapes and sizes.

A connecting member 2 is arranged at each intersection of the upper and lower elongated blocks 1 and 1. As shown in FIGS. 3 and 4, the connector 2 has a width 38 of the groove 1 a of the long block 1.
Two rectangular plates 2a, 2a, which are slightly narrower than about mm and thinner than the distance between the ridges 1c, 1c and the bottom surface, are vertically connected and fixed to each other via a columnar portion 2b. Then, as shown in FIG. 5, the lower rectangular plate 2a of the connector 2 is fitted into the groove 1a of the long block 1 installed on the lower side, and as shown in FIG. 2a is fitted into the groove 1a of the long block 1 placed on the upper side. Then,
The lower rectangular plate 2a is restricted from moving upward in the groove 1a of the lower long block 1 by the ridges 1c, 1c, and the upper rectangular plate 2a is in the groove 1a of the upper long block 1. Since the downward movement is restricted by the ridges 1c, 1c, the upper and lower elongated blocks 1, 1 are engaged with each other via the connecting tool 2. Therefore, the upper long block 1 can slide in the longitudinal direction of the upper and lower long blocks 1 and 1, respectively, so that the construction is not troublesome, and
Since it cannot move in other directions, positioning is stable and construction is easy. The connector 2 is not limited to such a configuration, and may be of any type as long as it can engage the upper and lower elongated blocks 1 and 1.

Above the lower long block 1 shown in FIG.
As shown in FIG. 5, the short block 3 is placed between the adjacent upper long blocks 1 and 1. The short block 3 is
As shown in FIG. 7, the same width as the long block 1 50 mm ×
The block has a rectangular cross section with a height of about 40 mm, but is formed with a short length of, for example, about 250 mm. Further, in the rectangular main body portion of the short block 3, rectangular through holes 3a, 3a which are divided into two in the width direction are formed in order to reduce the weight and save the material. The height of the short block 3 is 13 mm on the downward side surface in the figure.
An engaging portion 3b, which is a rectangular protrusion whose width is slightly narrower than about 38 mm of the groove 1a of the long block 1, is provided. The engaging portion 3b is also formed with a small rectangular through hole 3a for weight saving and material saving. Further, on both side surfaces of the engaging portion 3b, minute recessed lines 3c, 3c are provided along the longitudinal direction at positions sufficiently high from the bottom surface. In this short block 3, as shown in FIG. 8, the engaging portion 3b is fitted into the groove 1a of the lower long block 1 and the convex stripes 1 of the groove 1a are formed in the concave stripes 3c and 3c.
By fitting c and 1c, they are engaged in parallel on the lower long block 1. Therefore, the short block 3 can move only in the longitudinal direction of the lower long block 1 and cannot move in other directions, so that the positioning is stable and the construction is easy. The short block 3 may be manufactured by extrusion molding of plastic, or may be manufactured by another molding method.

When the upper long block 1 and the short block 3 are engaged on the lower long block 1, as shown in FIG. 9, these upper long block 1 and the short block 3 are engaged.
Are arranged in a lattice pattern. At this time, since the installation intervals of the lower long blocks 1 are arbitrary, the intervals in the vertical direction in the drawing in which the short blocks 3 are arranged can be freely determined. Also,
The arrangement interval of the upper long block 1 in the lateral direction in the drawing is also arbitrary, and if necessary, the short block 3 having another length can be used. Therefore, according to the lawn planting block of the present embodiment, it is possible to freely determine the size of the lattice pattern of the upper long block 1 and the short block 3. Then, this lawn planting block is filled with soil by the height of the upper long block 1 and the short block 3 shown by the one-dot chain line A in FIG. To complete.

Without using the short block 3,
It is also possible to plant the grass in a vertical striped pattern by narrowing the arrangement interval of the upper long blocks 1. Further, as shown in FIG. 10, the upper long block 1 may be diagonally arranged on the lower long block 1 to form a diagonal striped pattern. At this time, in the connector 2 shown in FIGS. 3 and 4, the upper and lower rectangular plates 2a, 2a are connected and fixed in a state in which they are twisted by a predetermined angle in advance.

Further, in the above embodiment, the case where the ridges 1c and 1c are provided in the grooves 1a of the upper and lower elongated blocks 1 and 1 has been described.
If you do not have to worry about lifting up, these ridges 1
c and 1c are unnecessary.

Further, in the above embodiment, the case where the lawn is planted between the upper long block 1 and the short block 3 is shown, but instead of this, other plants such as moss may be planted. However, it is not always necessary to plant a plant. Further, the long block 1 and the short block 3 on the upper side can also be used as line marks in a parking lot. At this time, if the color of the long block 1 or the short block 3 is changed, the line mark can be easily identified.

[0023]

As is apparent from the above description, according to the lawn planting block of the present invention, another long block or short block is provided on the lower long block at any interval or at any angle. Since it can be arranged with, it is possible to form a variety of arrangement patterns such as a lattice pattern or a diagonal striped pattern of any size. Further, since the upper long block and the short block are engaged with the lower long block by the connecting tool and the engaging portion, the positioning is stable and the construction is easy.
