Abstract

PROBLEM TO BE SOLVED: To provide a block which is used for a curb stone, can freely be arranged in the shape of a flower bed, even when the flower bed has a curved outer periphery, and can prevent water and the soil of the flower bed from oozing out due to rainfall, water spray, or the like, thereby enabling the maintenance of the beautiful appearance. SOLUTION: This block is used for making a curb stone arranged on the arbitrary shape-having outer periphery of the flower bed, or the like. The block 200 for the curb stone is formed by combining at least two virtual right circular cylinders 10, 10' having the approximately same identical radials and the approximately same heights, respectively, so that the axial lines 14, 14' of the virtual right circular cylinders are parallel to each other, wherein at least one of the virtual right circular cylinders has on its outside a recessed portion 16 having a shape capable of receiving the circular outer side of the virtual right circular cylinder.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a curb block,
More specifically, the present invention relates to a block in which a curb can be arbitrarily constructed in a place where a flowerbed, a roadside tree, or the like is planted, depending on the shape of the place.

[0002]

2. Description of the Related Art Flower cultivation, which is mainly ornamental, has been carried out by people since ancient times. Even today, houses, parks,
And various places such as streets are planted with flowers in each season.

To plant these flowers, for example, a flower bed is provided. In addition, a curb is formed on the outer periphery of the flowerbed by using blocks such as concrete blocks and bricks for the purpose of preventing scattering of soil in the flowerbed.

Particularly in recent years, in households having detached houses, gardening introduced from Europe and the like has become popular.
This is to grow blocks of roses, tulips, lavenders, etc. in the curb by arranging blocks around the flower bed of oneself. In gardening,
In addition to the flowers to be planted, the appearance of the flowerbed as a whole is important. That is, the shape and color of the curb are also necessary as conditions for improving the appearance.

Conventionally used blocks such as concrete blocks and bricks mainly have a rectangular parallelepiped shape, and when manufacturing a curb, these blocks are stacked along the shape of a flowerbed. Cement or the like is used for stacking.

However, a skilled technique is required to produce a curb using these blocks, and it takes a long time. Further, since these curbs are generally produced by fixing a block to the ground, it is very difficult to change the shape of the flowerbed and to replace it with a new block to change the appearance impression of the flowerbed itself.

Further, if the rectangular parallelepiped block is a flower bed having a square shape, a rectangular shape, or a combination thereof in plan view, it is possible to produce a curb without protruding the block ends at the corners of the flower bed. it can. However, in a curved flowerbed in a plan view, for example, a circular, elliptical, or gourd-shaped flowerbed, the curb obtained has a problem in that the joint between the blocks is distorted.

Japanese Unexamined Patent Publication No. 2000-106754 discloses that a curb can be produced in a short time, and a warp at a joint between blocks can be reduced even in a curved flowerbed, which is made of concrete or brick. Discloses blocks. The block described in Japanese Patent Application Laid-Open No. 2000-106754 has a basic structure in which two virtual cylinders having substantially the same shape are connected with their axes parallel to each other. According to this block, even in a curved flowerbed, the distortedness at the joint between the blocks is somewhat reduced as compared with the rectangular block.

However, in the curb manufactured using this block, since the outer surface of the block is a curved surface, the joints between the arranged blocks make line contact. As a result, the soil in the flowerbed is likely to seep out from the joint with water due to rainfall and watering. When such exuded soil dries, it remains as a stain on the surface of the curb, which deteriorates the aesthetics of the flowerbed as a whole.

[0010]

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION The curb block of the present invention is a combination of at least two virtual right circular cylinders having substantially the same radius and height and arranged so that their bottom surfaces lie in one plane. .

First, of the curb blocks of the present invention, 2
A block formed by combining two virtual right circular cylinders will be described.

FIG. 1 is a schematic diagram for explaining an example of a curb block according to the present invention, which is a combination of two virtual right circular cylinders. The curb block 100 of the present invention shown in FIG.
Represents the two virtual right circular cylinders 10 and 10 ′ with the virtual connecting surface 12
It has a shape formed by combining through. These virtual right circular cylinders 10 and 10 'have axes 14 and 14' parallel to each other, and a radius r and a height h which are substantially the same. Virtual right cylinder 1
0, 10 'are also arranged such that the bottom surfaces 15, 15' lie in a plane with each other. The size of the radius r is
Although not particularly limited, preferably 30 mm to 100 m
m, more preferably 40 mm to 80 mm. Height h
The size is also not particularly limited, but is preferably 40
mm-200 mm, more preferably 50 mm-100 m
m.

The curbstone block 100 of the present invention has, on the outer surface thereof, a recess 16 having a shape capable of accommodating the arc outer surface of a virtual right circular cylinder. As used herein, the term “arc outer surface of a virtual cylinder” refers to a part of the side surface of the virtual right circular cylinder 10 ′ or 10 forming the curb block, which also serves as the side surface of the block, and It refers to one side surface (curved surface) 18 of the circular arc column determined by the central angle θ as shown in FIG. This central angle θ is usually 120 °
It is the following.

Referring again to FIG. 1, the recess 16 formed in the virtual right circular cylinder 10 is another curb block 100 '.
It is provided so that the arcuate outer surface 18 (not shown) of the virtual right circular cylinder 10 '(not shown) can be accommodated in parallel along the generatrix direction of the concave portion 16 of the curb block 100. The concave portion 16 is preferably provided in a shape that can match the entire arc outer side surface (that is, to have a curved surface parallel to the entire arc outer side surface). Since the recess 16 substantially coincides with the arc outer side surface of the virtual right circular cylinder 10 ', the adjacent blocks 100 can be narrowed. As a result, a curb made using a plurality of curb blocks of the present invention does not produce a gap in an adjacent surface between one block and another block adjacent thereto or, even if it produces, a gap is extremely small. Because of the small size, it is possible to prevent the soil in the flowerbed from seeping out from this adjacent surface.

3 (a) to 3 (c) are top views of the curb block of the present invention. As shown in FIG. 3 (a), the recess 16 may be provided in any place in the virtual right circular cylinder 10 as long as it is located on the outer surface of the curb block of the present invention. In addition, the recess 16 provided
Is not limited to one. As long as each recess is provided independently (within geometrical constraints), a plurality of recesses 16, 16 'may be provided, as shown in Figure 3 (b). Furthermore, as shown in FIG. 3C, the recess 16 may be provided in both the virtual right circular cylinder 10 and the virtual right circular cylinder 10 ′.

The recess 16 is also preferably provided in the virtual right circular cylinder 10 as shown below. Figure 4
FIG. 2 is a top view of the curb block of the present invention shown in FIG. 1, which is a combination of two virtual right circular cylinders.

In the recess 16 provided in the virtual right circular cylinder 10, the distance R between the axis 14 of the virtual right circular cylinder 10 and the axis 14 'of the other virtual right circular cylinder 10' is expressed by the following formula (I):

[0028]

[Equation 5] Preferably satisfies the following formula (II):

[0029]

[Equation 6] It is more preferable to satisfy the following. Where r is the radius of the virtual right circular cylinder 10 (or 10 '); and a
Is the cutout length of the recess 16. The notch length a refers to the distance from the deepest portion A of the recess 16 to the intersection B between the radius r of the virtual right circular cylinder 10 passing through the deepest portion A and the outer periphery of the virtual right circular column 10. When the distance R between the axis line 14 of the virtual right circular cylinder 10 and the axis line 14 ′ of the other virtual right circular column 10 ′ satisfies the relationship of the above formula (I), a plurality of curb blocks of the present invention are arranged. It excels in providing a regular design when making curbs. In particular, if the distance R satisfies the relationship of the above formula (II), the curb obtained by arranging a plurality of curb blocks can provide a design in which all virtual right circular cylinders are regularly arranged. it can.

The curb block of the present invention also includes a basic structure formed by combining a plurality of virtual right circular cylinders,
An arbitrary pattern such as engraving may be provided on the outer surface of the block. Further, as shown in FIGS. 5A and 5B, an arbitrary curved portion may be provided in the connecting portion between the virtual right circular cylinders.

FIG. 6 is a schematic view for explaining still another example of the curb block of the present invention, which is a combination of two virtual right circular cylinders. The curb block 200 of the present invention shown in FIG. 6 has upper surfaces 22, 2 of each virtual right circular cylinder 10, 10 ′.
2'has substantially concentric projections 24, 24 'centered on the axes 14, 14' of the virtual right circular cylinder. further,
The curb block 200 has holes 28, 28 'on the bottom surfaces 15, 15' of the virtual right circular cylinders 10, 10 'about the axes 14, 14', which can be fitted into the protrusions 24, 24 '. By having these, when the blocks 200 are stacked in a plurality of stages, the alignment of the blocks in the upper stage and the lower stage becomes easy. In addition, since the upper block and the lower block are fitted and joined, the joining strength is increased.

Examples of the shape of the protrusions 24, 24 'include a column and a polygonal column. The shape is appropriately selected by those skilled in the art, but is preferably a cylinder. Due to the cylindrical shape of the protrusions, if the upper block and the lower block are arranged in different stages, it will be possible to rotate around the fitting part of one protrusion and its hole, and the appearance of the obtained curb will be free. It can also be changed to

The shapes of the holes 28 and 28 'are as follows.
The shape is not particularly limited as long as it is a shape that can be fitted to the protrusions 24, 24 ′, and is appropriately selected by those skilled in the art. Preferably, the shape is such that it can have three or more points of contact with the protrusions. Examples include polygons such as triangles and squares, and circles. More preferably, the holes are provided with the same size and shape as the protrusions. As a result, the fitting strength between the upper block and the lower block can be increased.

The curb block of the present invention also has the above-mentioned projections and holes to improve the stability when stacked. Further, the distance R between the above two virtual right circular cylinders
Is the following formula (II):

[0035]

Are projections 24, 24 ', 2 on the bottom surface of the virtual right circular cylinders 10, 10', 10 "in a substantially concentric pattern about the axis.
Each of the protrusions and holes is preferably of the same size.

Next, among the curb blocks of the present invention,
A block including only one virtual right circular cylinder will be described.

FIG. 9 is a schematic view of the block for explaining an example of the curb block of the present invention including only one virtual right circular cylinder 10. The curb block 400 of the present invention shown in FIG. 9 has the same radius and height as the curb block made of the above two virtual right circular cylinders.

The curbstone block 400 of the present invention has at least one concave portion 16 on the outer surface thereof, which has a shape capable of accommodating the arc outer surface of the virtual right circular cylinder.

The curbstone block 400 of the present invention may also have substantially concentric projections 24 on the upper surface of each virtual right circular cylinder 10 about the axis 14 of the virtual right circular cylinder. Further, the curbstone block 400 has the projections 24 formed on the bottom surface of the virtual right circular cylinder 10 in a substantially concentric shape centered on the axis 14.
It has a hole 28 that can be fitted into. It is preferable that each protrusion and each hole are provided in the same size.

By using two curb blocks 400 of the present invention in combination, a curb block 100 of the present invention as shown in FIG. 1 having substantially the same shape can be obtained. The curbstone block 400 of the present invention composed of one virtual right circular cylinder is used in combination with the curbstone block composed of the above-mentioned two, three and / or more virtual right circular cylinders, whereby a curb can be further formed into an arbitrary shape. Can be produced.

Regarding the curb block of the present invention, each block when several virtual right circular cylinders are used has been described, but the material used for the curb block itself of the present invention is not particularly limited. Examples of the material include synthetic resin, concrete, brick, metal, stone, and wood. It is preferably made of synthetic resin because it is lightweight and easy to mold. Further, by mixing an appropriate amount of filler such as wood powder and stone powder into the synthetic resin, it is possible to give the surface a unique design such as wood grain or marble pattern.

When the curb block of the present invention is made of, for example, a synthetic resin, a method well known in the ordinary synthetic resin molding field is appropriately selected by those skilled in the art. For example, an injection molding method, a blow molding method, and a vacuum molding method can be mentioned. On the other hand, it may be manufactured by a technique such as cutting.

When the curb block of the present invention is manufactured by, for example, an injection molding method, the inside of the block is preferably molded into a hollow shape having a lattice-like reinforcing structure. This makes the block lighter and easier to transport in large quantities. Moreover, sink marks and the like do not occur when the molded product is cooled, and a good appearance can be obtained.

The curb block of the present invention is used to produce a curb as follows. Here, a case will be described in which a curb block 200 including two virtual right cylinders as shown in FIG. 6 is used to manufacture a curb around a flower bed.

First, for example, as shown by the broken line in FIG. 10, the shape of the flowerbed is determined when making a curb. Block 2 for the curb on the first stage along the outer edge of the flowerbed
00 is arranged. Since each block 200 is provided with the concave portion 16, the adjacent blocks 200 can be arranged at a desired angle while maintaining a narrow state. As a result, the plurality of blocks 200 are arranged along the outer circumference of the flower bed. At this time, when the block is made of synthetic resin and formed into a hollow shape, the weight of the block may be increased by filling the inside of the block with soil or the like in order to obtain stability of the block in the first stage.

Next, the second-stage curb block 200 is stacked on the first-stage block 200, for example, in different steps. In stacking, the protrusions 24 and 24 'are provided on the upper surface of the block 200 and the holes 28 and 28' (not shown) are provided on the lower surface of the block 200, for example, in a cylindrical shape. The eye block 200 is rotatably fitted and joined. The blocks 200 of the second stage can be rotatably fitted and joined to each other to form an array substantially the same as the array in which the blocks 200 of the first stage are arranged. Further, a joint fixing material such as mortar or an adhesive may be applied to the joint surface for the purpose of improving the joint strength between the blocks. On the other hand, if such a joint fastening material is not used, the block can be easily removed, and the shape and / or movement of the flower bed can be easily changed even after the curb is manufactured. In this way, the curb of the flowerbed is produced.

[0053]

According to the present invention, the concave portion 16 provided on the outer side surface of the virtual right circular cylinder in one curb block and the arc outer side surface portion of the virtual right circular column in the other curb block coincide with each other. Therefore, these curb blocks can be narrowed at any angle. Further, by providing the projections on the upper surface of the block and the holes on the lower surface of the block, the upper block and the lower block can be firmly stacked without a gap. As a result, it is possible to prevent the soil of the flower bed from seeping out with water from the adjacent surface between the blocks due to rainfall, water sprinkling, etc., and the aesthetic appearance of the curb itself can be maintained.
