Description

[Detailed Description of the Invention] The present invention relates to the structure of a court for a sports facility.

Conventional courts for sports facilities use a relatively wide coating material of a predetermined width and uniform thickness, which is spread over a pre-formed base material layer, with each bonded part forming a straight line. It had been. In such sports facilities (tennis, volleyball courts, etc.), that is, in each court, the court material expands and contracts due to temperature and humidity differences that change depending on the four seasons. The peripheral edge changed, forming a partially uneven peripheral edge, detracting from the overall aesthetic appearance of the coat.

However, the object of the present invention is to obtain a structure of a court for a sports facility that has the excellent advantage of eliminating the above-mentioned disadvantages at once and the advantage of being inexpensive to construct.

To explain the gist of the present invention created to achieve such an objective, the periphery of each side of a quadrilateral shape has alternating wavy-shaped recesses and wavy-shaped protrusions,
In addition, a coating material made of rubber or synthetic resin having a uniform thickness is formed, and on the upper surface of the base material layer formed on the court for sports facilities, the coating material adjacent to the corrugated recesses of the coating material is formed. Each coat is coated so that the wavy convex portions are alternately fitted into the wavy concave portions of the other wavy convex portions, so that no gaps are created between the contact surfaces of the wavy concave and convex portions. This is the structure of a court for sports facilities that is characterized by being paved with lumber.

Furthermore, each corner where each side of the quadrilateral shape constituting the coating material intersects is made to have the same shape as each side constituting the quadrilateral corner coating material made of rubber or synthetic resin and smaller than the coating material. The structure of a court for a sports facility may be obtained by cutting the coat material and fitting the coat material and the corner coat material.

An embodiment of the present invention will be described with reference to the drawings.
A has wave-shaped concave portions 2 and wave-shaped convex portions 3 continuously formed alternately and symmetrically on the peripheral edge 1 of each side of a quadrilateral shape, and is suitable for sports and walking, and has appropriate elasticity. This mat-like coating material is made of rubber or synthetic resin and has a uniform thickness. b is the coating material of the second embodiment. That is, each corner where each side of the coating material a intersects is smaller in shape than the coating material a, and has the same shape as each side of a quadrilateral corner coating material b' made of the same material as the coating material a. It is formed using the cut shape. 4 is the top of the corner coating material b', and 5 is the peripheral edge.

The combination fitting of each of the coating materials a and b and the corner coating material b' as described above (however, in the case of only the coating material a, the corner coating material b' is not necessary) is as shown in the drawing. Reference numeral 8 indicates a base material layer constituting the structure of the court for sports facilities according to the present invention, 9 indicates a surface layer coated on the surface of the constructed court according to the present invention, and A indicates a tennis court constructed according to the present invention. Incidentally, the coating materials a, b and corner coating material b' of the present invention can also be applied to architectural floors.

With conventional coating materials that have a straight edge on each side of a quadrilateral shape, each coating material expands and contracts due to temperature and humidity differences that change depending on the four seasons.
In particular, the linear peripheral edges on each side where the coating materials are in contact change to form partially uneven peripheral edges, detracting from the overall aesthetic appearance of the coat.

On the other hand, the coat constructed according to the present invention has corrugated irregularities 2 and 3 on the peripheral edges 1 and 5 of the coating materials a and b.
Since the coating materials a and b are formed in a continuous manner alternately so that they fit into each other, when the temperature rises as in summer, the convex portions 3 at predetermined locations in the peripheral edges of the coating materials a and b become microscopic. Even if there is a minute change in the wave shape of the uneven portions 2 and 3 and the wave shape is slightly deformed and imbalance occurs, both coats Peripheral parts 1 of materials a and b,
Since the coat has a wavy shape from the time when the coats 5 are fitted together, the wavy shape deformed by the stretching does not give a strange feeling and does not spoil the aesthetic appearance of the coat.

(1) As mentioned above, the present invention is based on the overall shape of the coating material, in which symmetrical concavities and convexities are alternately formed in a continuous manner with each peripheral edge having a wave-like shape, and various coating materials are fitted into each other. After the coating has been applied, the convex portions at predetermined locations within each peripheral edge of the coating material expand slightly due to temperature and humidity differences that change depending on the seasons, and press against the peripheral edge of the opposing concave portion. Even if there is a slight change in the wavy shape of the uneven portion, causing the wavy shape to be slightly deformed and unbalanced, the wavy shape will remain as the peripheral edges of both coating materials fit into each other. Therefore, the wavy shape deformed by the above-mentioned stretching does not give a strange feeling and has the advantage that it does not impair the aesthetic appearance of the coat.

(2) Furthermore, the coat of the present invention can be constructed extremely easily by separately preparing a predetermined shape in advance and combining and fitting them as described above.
Therefore, it has advantages such as lower construction costs.
