Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rug suitable for use in ball games such as gateball or crotchet, in which a ball is hit with a stake and rolled.

In recent years, games such as gateball have been adopted as sports suitable for the elderly, but there are restrictions on their use indoors, such as in general gymnasiums, as the floor surface can be damaged by the blows of the sticks. ,
Another drawback was that the ball rolled too much on a smooth floor.

To overcome these drawbacks, commonly used artificial turf, rubber or plastic sheets are used, but although the problem of damaging the floor surface is eliminated, the problem of the ball rolling too much cannot be eliminated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ball game rug that is lightweight, easy to install and remove, and allows balls to behave in a manner similar to that on a dirt court.

Next, embodiments of the present invention will be described based on the drawings.
In Figure 1, 1 is a large mesh structure with a diameter of 5 mm and a mesh size of 35 mm, which is made of a core material made of a polyester knitted fabric and coated with soft polyvinyl chloride on the surface. The upper surface of the body 1 is made of a mesh made of polyester knitted fabric as a core material and a surface coated with soft polyvinyl chloride, with a diameter of 2 mm.
Small mesh structures 2 having a mesh size of 7 mm are laminated together by gluing or sewing so that the meshes thereof are diagonal to the direction of the mesh of the large mesh structure 1.

On the back surface of the large mesh structure 1, an anti-slip layer 3 made of a polyvinyl acetate film is provided along the constituent material.

FIG. 2 shows another embodiment of the present invention, in which a fabric 4 is adhered to the back surfaces of the mesh structures 1 and 2 stacked on top and bottom of the first embodiment, and An anti-slip layer 3 made of a polyvinyl acetate sheet is provided on the top.

In addition to the mesh structure made of fiber and plastic as mentioned above, the mesh structure can be made entirely of fiber,
It may be made of rubber or plastic, and the mesh may be formed by making discontinuous cuts in a rubber sheet or plastic sheet in a staggered manner and spreading them laterally to form a mesh.

In the above embodiments, the small mesh structure and the large mesh structure are stacked one above the other in this order, but the small mesh structure is not integrally woven into the large mesh structure. In any case, the upper surface of the small mesh structure is approximately at the same height as the upper surface of the large mesh structure or is protruded above the upper surface of the large mesh structure, and the lower surface of the large mesh structure is must protrude below the lower surface of the small mesh structure.

In addition, the anti-slip layer provided on the back side may be made of a material with high friction such as rubber or soft plastic, especially when foamed plastic is used.
It becomes more familiar with the floor surface, and when walking on the upper surface,
This is preferable because it produces a cushioning effect. If the large mesh structure is constructed or covered with a flexible foamed plastic, there is no need for a separate anti-slip layer on the back side. The ball rolls on the surface of the large mesh structure and the small mesh structure, and when the ball rolls, the dents in the small mesh structure act as rolling resistance and provide a deceleration effect. If it is too large, the small mesh structure will be too concave and the ball will not roll smoothly. If it is smaller than 10 mm, the small mesh structure will have a small depression and the ball will not be slowed down, and if the material of the large mesh structure is smaller than 1 mm. If it is too small, the recess of the small mesh structure will be small and the ball will not be slowed down, and if it is larger than 10 mm, the small mesh structure will be too recessed and the ball will not roll smoothly, and it will be heavy and difficult to transport and store. If the material of the small mesh structure is smaller than 0.3 mm, the durability will decrease and the mesh will break easily, and if it is larger than 5 mm, the weight will be heavy and transportation and storage will be difficult, and the mesh of the small mesh structure will be 1
If it is smaller than mm, it will be heavy and difficult to transport and store, and if it is larger than 15 mm, it will be difficult to carry when hitting,
It becomes impossible to protect the floor surface when walking or running.

In addition, in order to facilitate transportation and storage, the rug may be made into equal parts of the coat and connected with fasteners, and a thin part may be provided at the position where the coat is divided into equal parts so that it can be folded. Good too.

If the upper surface is colored green or brown, the ball will be easier to see and the game will be more interesting, and it will be convenient if the playing line part is colored white in advance.

It is preferable to provide a transparent protective layer on the colored upper surface because the surface of the ball will not be contaminated even by a spark hit made by stepping on the ball with a foot.

The ball game rug of the present invention is made of a material with an outer diameter of 1 to 10 mm, a large mesh structure formed into a mesh with a size of 10 to 60 mm, and a material with an outer diameter of 0.3 to 5 mm, and the size is A small mesh structure formed into a mesh of 1 to 15 mm is laminated together, and the upper surface of the small mesh structure is approximately at the same height as the upper surface of the large mesh structure, or is higher than the upper surface of the large mesh structure. Since the lower surface of the large mesh structure is projected downward from the lower surface of the small mesh structure, the small mesh structure on the mesh of the large mesh structure is dented when the ball rolls, resulting in a ball. This provides resistance to the rolling of the large mesh structure, resulting in an appropriate rolling method similar to that on the soil surface coat, and compared to the case where the upper surface of the large mesh structure protrudes upward as in the invention of Japanese Patent Application No. 57-191038. However, the ball rolls more smoothly and irregular rolling does not occur. In addition, when installed in a general gymnasium, tennis court, etc., the presence of the small mesh structure allows the stake to play gateball without damaging the floor or court surface, and is lightweight, making it easy to install, remove, transport, and use. Storage can be done easily.

If the mesh structure is laminated in such a way that the mesh direction of one mesh structure is diagonal to the direction of the other mesh structure, as in the example, the structure will be strong against external forces in any direction, and the mesh will not become misaligned. It can be prevented.

Further, when a sheet-like material is laminated on the back side, the floor surface is covered with the sheet-like material, so that dirt on the floor surface due to competition can be reduced.
