Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a sports court that has appropriate elasticity to give a good playing feel and is water permeable and suitable for ball games such as tennis and gateball. .

[Conventional technology]

Conventional water-permeable sports courts are made of an artificial turf-like material laminated with a water-permeable cushion layer, and are expensive.

In addition, an artificial turf-like material with piles planted on top of the flat soil, such as the so-called Omnicourt (registered trademark), is laid down, and sand material is spread on the top surface to the extent that the tips of the piles are slightly visible. The coats thus formed are becoming relatively widely used because they have a good playing feel.

However, the disadvantage of this court is that the sand material laid on the top surface of the artificial turf material solidifies and washes away over time, so a means of correcting this is required, and also, as the sand material moves and becomes lopsided, some areas may become uneven. This can cause unevenness on the court over time, and the extent of this becomes even greater when the tips of the piles of artificial turf are worn out. This has the disadvantage that repairs are troublesome and maintenance and management costs a lot of money.

[Problem that the invention attempts to solve]

This invention was made in view of the actual situation,
It has many advantages, such as eliminating the movement of sand, that is, sand escape, preventing sand from solidifying, maintaining an excellent playing feel equal to or better than the above courts, and being much easier to maintain. The present invention seeks to fundamentally improve the prior art, especially with respect to sand consolidation and migration.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention consists of: (a) a water-permeable third layer made of asphalt concrete, etc., and (b) cushioning members of an appropriate thickness are interspersed on the upper surface of the third layer. c) a second layer formed by filling a permeable sand material or the like into the gap where the cushion member is not present, at approximately the same height as the said member; and a first layer formed by fixing a part of the back side of an artificial turf-like material which is provided and lined with water permeability to the cushion member with an adhesive or an adhesive. It is valid as a summary.

The present invention will be described below based on embodiments with reference to the drawings.

〔Example〕

FIG. 1 is a cross-sectional explanatory view showing a sports court according to the present invention.

For convenience of explanation, we will start from the third layer, which is the lowest layer. The third layer is made of asphalt concrete or the like having relatively good water permeability, and a central drainage groove 1a is provided in the lower part as necessary.

Next, the second layer provided thereon is the most important feature of the present invention, and is particularly unique in that it can completely prevent the solidification and movement of sand materials in the prior art. That is, as shown in FIG.
It is made up of 7mm cushion members 3 scattered almost regularly, and the net-like material 2 has relatively coarse mesh made by knitting and woven by arranging threads made of natural fibers, synthetic fibers, etc. in the warp and warp directions. The cushion member 3 is made of soft plastic such as PVC, polyethylene, etc., made of lumps arranged at approximately the same height, and is flexible and elastic. It is formed by adhering to the mesh of a rich net-like material. In the present invention, a water-permeable sand material 4 is placed in the gap where the cushion material 3 is not placed.
It will be filled to almost the same height. If the ground is somewhat uneven, you can cover the unevenness with sand, etc.

This second layer has water permeability in the sand material 4 part and can be made to have elasticity by the cushion material 3, so it has good drainage, and
It is the basis for creating a court with a good playing feel.

Next, the top first layer is made of pile 6 on the base fabric 5.
An artificial turf-like material 8 comprising a backing 7 having water permeability and a part of the back surface being coated with a pressure-sensitive adhesive or an adhesive 9 applied by a roller or spray to form the cushion of the second layer. It is fixed to the material 3, and water permeability is maintained except for the fixed part. The purpose of fastening is to prevent the first layer of artificial grass from becoming loose and loosening when the coat according to the present invention is used. Furthermore, the sand material filled in the second layer has the remarkable effect of preventing its solidification and movement because it is hidden by the artificial turf-like material.

[Effect of idea]

The present invention is based on the above structure, and has a structure in which a cushion body and a filling portion such as sand are placed on the upper surface of a water-permeable third layer made of granular material such as asphalt concrete. Two layers are provided, and the second layer is lightly attached to the second layer.
Sports that use this type of court, such as tennis,
The first artificial turf-like material suitable for ball games such as gateball
It has a structure that allows water to pass through easily in each layer, so that rainwater, etc. does not stay on the top surface of the first layer for a long time, and the upper two layers, especially,
Since the second layer has a cushion material, the cushioning properties of the court are extremely good.In addition, the sand material located in the second layer is covered with the cushion material and the upper part of the artificial turf lining of the first layer. It does not move and is hidden by the first layer, which prevents natural hardening and maintains a favorable condition over time.It is also easy to repair, and the exposed first layer etc. can be repaired. It has many advantages, such as being able to be replaced and repaired in a patchwork manner by cutting out only certain parts, and is extremely useful as it can be applied to many sports courts.
