Description

{Flooring material of sports stadiums}

The present invention relates to a flooring of a sports indoor arena of a NeXT COAT indoor and outdoor sports field, and more particularly, to a plastic tile or floor covering supported on a floor surface to provide a sports arena surface such as basketball, tennis, futsal, A plurality of shock absorber columns and a shock absorbing coupling column are provided on the bottom surface of the prefabricated sports court to maintain a continuous square lattice structure and a shock absorbing member inserted between the shock absorbing column and the shock absorbing coupling column The present invention relates to a flooring material of a NeXT COAT indoor and outdoor sports arena, which has an effect of mitigating shocks generated during a heavy exercise by dispersing a load of a person.

A wide range of floor coverings has been developed for use as a stadium floor for athletic activities. For example, hardwood floors are comfortable in bounce characteristics, but are difficult to repair and maintain because of their high cost, . However, such flooring always has the risk of injury such as abrasion to the player who has fallen on the floor. Therefore, the timber and the fixed floor tile or cement floor are used for the athletes performing physical activity, It can not absorb a lateral impact force common to sports activities including sudden changes.

A conventional known technique is 'lateral impact force absorbing modular tile' of Registration No. 10-0075841-0000 (1994.07.28).

The 'lateral impact force absorbing modular tile' is structurally made of a plastic material as a modular tile, and generally adopts a grid structure so that the tile surface extends downward from the grid intersection Is a cross pattern having support legs that are spaced apart from one another.

The patent further discloses the use of expansion joints and cross-stiffening members or stiffeners, wherein the grid structure is a modular tile having a continuous flat surface and is rather prone to bending and distorting, And tends to be more twisted and bent when received. As a result, the prior art has made it impossible to use plastic tiles with continuous, flat surfaces and in a modular, cyclic manner.

The main reason for avoiding flat, continuous surfaces is the difficulty of producing and maintaining plastic tiles that lie at the same height on the support floor surface without adhesive, despite changes due to temperature and long-term use, The temperature change can cause the tile to bend and limit the effective use of the tile floor, such as the surface that comes in contact with sunlight or fire, as well as lifting the vertex or edge, creating a safety hazard, There is a problem that the blurring of the breakage occurs rapidly due to the force or the frictional force in the lateral direction or the diagonal direction caused by the exerciser and the user.

Also, in the case of rainfall, there is a problem that drainage is not easy in the case of tile adhered to the floor of hardwood or cement floor of a game.

In order to solve the above problems, the applicant of the present invention has filed a patent application No. 10-0901434 entitled "prefabricated sports court ", and the prior art invention maintains a continuous square lattice structure inside, And an outer frame portion including a vertex supporting leg for dispersing a load applied by the coat and a corner supporting leg, and a cross-linking portion and a coupling portion for guiding the coupling, and includes an X-shaped reinforcing rib formed inside the lattice structure A rectangular shaped sports coat block and a rectangular outer frame are used as constituent elements, and a continuous rectangular lattice structure is held in a single line, and in particular, both of friction and safety imposed during the use of a sudden lateral force Spore of plastic components that are engaged to form the required arena surface Tsukot.

However, the conventional invention has an excellent effect of forming a race surface requiring both abrasion and safety imposed during the use of a sudden lateral force in use, but does not have a device capable of mitigating the impact, As it is.
