Description

[Detailed Description of the Invention] The present invention relates to an elastic floorboard that is used by being laid on the floorboard of a gymnasium or the like.

Gymnasium floors are generally not made to be particularly elastic, and during floor exercises in gymnastics competitions, a carpet-like rug called a visor is spread over the floorboards, but this slightly cushions the impact. If the performance fails, it is easy to get injured,
In addition, even if there was no failure, there was a high risk of injury to the Achilles due to the impact upon landing.

In view of the above-mentioned circumstances, the present invention was developed with the aim of providing a useful elastic floorboard that can be laid on the floorboards of gymnasiums and used mainly for practice. A large number of elastic materials are fixed at the same height on the surface of the bottom plate, and on top of the elastic materials, appropriate intervals are placed on the back side of each of two pairs of opposing peripheries made of plywood of the same size as the bottom plate. and two connecting fittings are provided to protrude from one side, and an upper plate is provided with connecting fittings protruding from the side at positions corresponding to the outside of the two connecting fittings on the back surface of the other side. It is characterized in that it is fixed and a carpet-like overlay is pasted thereon via an elastic plate.

Next, an example of implementation of the present invention will be explained with reference to the drawings.

1 is a rectangular bottom plate made of plywood; 2 is the bottom plate 1;
An elastic material made of an elastic material such as neoprene (commercially available) is fixed in appropriate numbers at equal heights on the four sides and the center of the surface. 3 is an upper plate fixed on the elastic material 2 and is the same size as the bottom plate 1. It is made of thicker plywood, and two connecting metal fittings 4, 41 are provided on the back side of one side of each of the two pairs of opposing peripheries, projecting from the side at appropriate intervals, and on the back side of the other side. Connecting fittings 42 and 43 are provided at positions corresponding to the outer sides of the connecting fittings 4 and 41, respectively, so as to protrude from the sides.

5 is an elastic plate made of an elastic material such as neoprene (commercially available) and is the same size as the upper plate 3 and is attached to the surface of the upper plate 3. The elastic floorboard A is constituted by the carpet-like overlay that covers the circumferential side of the board 5, but usually the bottom board 1
is 1200mm x 2400mm and about 5-10mm thick.
Elastic material 2 is 50 mm x 200 mm and approximately 6 mm thick, upper plate 3 is approximately 15 mm thick, and elastic plate 5 is
The connecting fittings to be attached to the upper plate 3 are approximately 50 mm x 240 mm and approximately 6 mm thick, protruding approximately 60 to 70 mm from the upper plate 3. It can be attached using screw 7 and nut 8.

The elastic floorboard A of the present invention configured as described above is
As shown in Figure 4, the large number of sheets are arranged so that the connecting fittings 4, 4 and 43, 43 of one floor plate are sandwiched between the connecting fittings 42, 42 and 41, 41 of the other floor plate, respectively. It is used by being fitted onto the floorboards of gymnasiums, etc., and as mentioned above, the connecting fittings are fitted with the connecting fittings of the floorboards to be connected on the four sides of the floorboards. Therefore, after installation, each floorboard is firmly connected and there is no risk of it shifting or distorting.In addition, the elastic material 2 is interposed between the bottom board 1 and the top board 3, and the space between the top board 3 and the top board 6 is Since the elastic plate 5 is interposed between the upper and lower floors, the overall structure is rich in elasticity and has good cushioning properties, and the risk of injury even if you fail in performing exercises such as floor exercises is significantly reduced compared to conventional methods. The elastic plate 5 interposed between 3 and the overlay 6 can reduce the impact upon landing and prevent the Achilles injury accidents that are often caused by the impact upon landing, thereby increasing safety. It has high performance and low noise, making it suitable for use in practicing gymnastics competitions, and convenient for storage as it can be easily separated into individual parts when not in use.

In addition, the connecting fittings 4, 41,
42 and 43 shall be attached only to the connecting side when the floorboards are connected in one direction only, and to the four sides when connected in both directions. , and the outermost one should not be attached to its open side to prevent the metal fittings 4 from protruding to the periphery after the floor is formed.

Since the present invention is as described above, it is suitable as an elastic floorboard to be laid on the floorboard of a gymnasium, etc. and used for gymnastics practice, etc., and its structure is simple, easy to manufacture, and can be provided at low cost. .
