Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the field of structure of courts for sports facilities and the like.

(Prior Art) Conventionally, a tennis court structure in which a coating material such as a chip rubber material is formed on the flat upper surface of a base material layer is disclosed in Japanese Patent Application Laid-Open No.
Publication No. 114029 was published. Furthermore, Japanese Patent Application Laid-open No. 111557/1983 describes a method in which sand, antucar, etc. were laid down. Furthermore, as a multi-purpose elastic floor structure, Japanese Patent Laid-Open Publication No. 195263/1983 has an elastic layer formed on the upper surface of a base material layer, and a sealing layer formed on the upper surface.

(Problems to be solved by the present invention) Unlike the conventional court structure, the present invention has a good ability to absorb rainwater, and also has a water-retaining function in the summer, keeping athletes cool. It has a number of excellent advantages, such as promoting the reduction of radiant heat generated under the scorching sun and preventing players from becoming fatigued, as well as being extremely easy to construct the entire court, resulting in low construction costs. It is.

(Means for solving the problem) A coating material of irregular shape and uniform thickness made of chip-shaped rubber material is formed on the flat upper surface of a base material layer such as asphalt or concrete. A countless number of circular through holes or circular recesses formed in the material and countless recesses formed on the surface of the coated material are each filled with sand, Anzuker, etc., and the through holes are filled with sand. etc. and the sand etc. filled in the recess are approximately the same height, and furthermore, a through hole such as a circular shape formed in the coating material such as a rubber material, the recess and the countless number of holes formed on the surface of the material. This is a structure of a court for a sports facility, etc., in which relatively small recesses are filled with sand, sand, etc.

(Example) 1 is a base material layer such as asphalt or concrete, and the upper surface is usually formed in a flat shape.
Reference character a is a resilient coating material formed on the upper surface of the base material layer 1 made of a rubber material or the like and having an irregular shape and a uniform thickness. The surface of the coating material a as described above is flat, but due to the constituent materials of the coating material a, numerous recesses 2 are formed although the shape is irregular. and,
When sand 3 or antuker or the like is spread on the surface of the coating material a and leveled using a broom or the like, the sand 3 fills into the recess 2. Therefore, the sand 3 that is not filled into the recess 2 is removed. As a result, the surface of the coating material a becomes even more flat. As described above, instead of the sand 3, the filler in the recess 2 may be filled with powder made by crushing Anzukar, coal, coke ash, bricks, etc. In addition to the material to be filled, it is also possible to use a mixture of the sand 3 and other substances.

In addition to the above-mentioned shape, the present invention also provides for the constituent material of the coating material a to be made of a rubber material having a square shape, for example, a relatively large and irregularly shaped cube, or a synthetic resin material having elasticity. It may be formed to have a predetermined thickness. When a material having the above shape is used, the shape of the recess 2 formed on the surface of the coating material a is relatively large, and the sand 3 etc. to be filled is also larger than the recess 2 of the coating material a described above. This results in slightly more filling.

For the coating material a as described above, the through holes 4 are usually formed at right angles to the flat surface of the coating material a and have a circular, triangular, polygonal, etc. cross-sectional shape, although the shape is not limited. , or formed into countless numbers at the same time using an irregular die-cutting method or during the manufacturing process. In the case of such coating material a, the recesses 2 and the through holes 4 are filled with sand 3 and the like.

Furthermore, in place of the through holes 4, the coating material a is formed with numerous, for example, circular recesses 5 at predetermined intervals on the inner side of the relatively large surface of the coating material a. Both the recesses 2 and 5 of the coating material a formed as described above are also filled with sand 3 or the like alone or in a mixture.

In addition to the above, in the present invention, the shape of the coating material a has a through hole 4 such as a circular shape, a recess 5 and a recess 2.
It is also possible to form a mixture of an infinite number of sand 3 and the like, and in this case, the sand 3 or the like alone or as a mixture is filled in the same way as described above.

The coating material a having various shapes as described above is
During the manufacturing process of the coating material a itself, it goes without saying that they are formed at the same time, but after it is laid on the surface of the base material layer 1, the through holes 4 and the recesses 5 other than the recesses 2 are formed using separate equipment. It is a good thing,
The method doesn't matter.

Separately from the above coating material a, a coating material of coating material a is formed on the surface of the base material layer 1 by mixing and stirring a rethane rubber material and an adhesive.
It is applied on site to a predetermined thickness (for example, about 7 to 8 mm), and while it is still relatively soft after installation, it is pressed using a pushing tool to form a recess. After solidification, the recesses etc. are filled with sand 3, etc. singly or as a mixture until they become flush with the flat surface of coating material a, and the unfilled sand 3, etc. is removed.

In the present invention, the connection surfaces of each coat material a formed as described above are laid on the top surface of the flat base material layer 1, and the joint surface of each coat material a separates, which may interfere with the sports etc. of the athletes. For example, the connection method that does not involve
We will construct it with a structure similar to No. 64712.

(Function) To explain the function of the present invention, when playing an appropriate sport such as tennis or volleyball on the court of the present invention, any part of the sole of the shoe worn by the players may be affected by the court material a. are located on the top surface of countless recesses 2, through holes 4, and recesses 5 formed on the surface of coating material a. Through hole 4
When the sand 3, etc. filling the recess 5 absorbs and is simultaneously subjected to a directional impact force, the characteristics peculiar to the particles of the sand 3, etc. change slightly. Therefore, this change causes a slight slipping phenomenon on the entire surface of the sole located above the recess 2, through hole 4, etc. This point is completely different from conventional coats.

Furthermore, the present invention provides for the recesses b and through holes 4 of the coating material a.
The sand 3 and the like filling the recesses 5 absorb rainwater, making it easier to dry the entire court, and making rainwater removal work more efficient than in conventional courts.

In addition, in the present invention, when water is sprinkled over the entire court in the summer, the sand 3 filled in the recesses 2, through holes 4, and recesses 5 absorbs water and exhibits a water retention function, and absorbs heat on the court during evaporation. This has the effect of lowering the temperature and reducing radiant heat, making it easier to play sports in the summer.

In addition, if the sand 3 during filling adheres to the sole surface of the shoe during sports or is washed away even slightly during rain, and the sand 3 is reduced, sprinkle the sand 3 on the surface of the coating material a again, and use a broom etc. after spreading. The insides of the recesses 2, through holes 4, etc. may be additionally filled with the material.

In addition, in the present invention, since the sand 3 filling the inside of the recess 2 and the through hole 4 is in the form of fine particles, even if an impact force is applied, the dent caused by compression is small, so the sole surface of the shoe will not be buried. This allows for smooth competition.

(Effects) (1) As mentioned above, the present invention forms a mixture of numerous recesses, through holes, and recesses on the entire surface of the coating material, and sand etc. The structure of the court is such that the soles of the players' shoes are located in the through-holes and above the recesses, and impact forces of different strengths and weaknesses are applied to each recess and the surface of the through-holes. Even when the sand is applied to the feet, toes, and lower back, the particulate sand filled in the through-holes and the recesses shakes and gives a comfortable twist to the entire shoe. The twist is about the same as when the player is in the middle of the game, which has the advantage of further eliminating injuries and fatigue for athletes compared to conventional methods.

(2) Furthermore, the present invention has a shape that is a mixture of countless recesses, through-holes, and recesses, and by filling these recesses and through-holes with sand, etc., the entire court is different from that of a conventional court. In comparison, the condition is more similar to that of a clay court, so it has the advantage that you can fully enjoy playing soft tennis.

(3) Furthermore, the coat of the present invention has recesses filled with sand, etc. formed in the coating material, through-holes, and recesses.
Since it absorbs more rainwater than conventional coats, the work of removing rainwater from the coat can be shortened compared to conventional coats, increasing work efficiency. In the summer, the radiant heat on the court surface is further reduced, allowing athletes to play in a cooler atmosphere, and it also has the advantage of significantly reducing fatigue compared to conventional courts.

(4) The coat of the present invention is extremely simple and strong, and the construction costs are low, and the present invention has a number of extremely remarkable practical effects.
