Description

[Detailed Description of the Invention] The present invention relates to the floor structure of a gymnasium, and more specifically, the invention relates to the floor structure of a gymnasium, and more specifically, to the floor structure of a gymnasium that has been purchased or on top of this floor so that the floor can be elastically supported according to the load applied to the floor surface. This relates to floor structures installed for competitions such as gymnastics.

The floors of gymnasiums and the like are supported as a whole to have a predetermined elasticity.

This is to give the competitors the same elasticity as the earth.

Various types of floor structures that provide elastic support in this manner have been known.

Various structures are known, ranging from simple ones in which an elastic material such as rubber is attached to the underside of the floor, to more complex ones in which a large number of independent elastic support members are arranged.

The present invention is an improvement on the conventional elastic support member for the floor, and it is possible to reliably support the floor surface using the coil springs h, and it is extremely easy to replace the coil springs when replacing them. The present invention provides a floor structure for a gymnasium that is configured to allow the following activities to take place.

The present invention will be explained in detail below along with an embodiment shown in one drawing.

FIG. 1 and subsequent figures illustrate one embodiment of the present invention. In the electrical diagram, the floor, which is indicated by reference numeral 1 as a whole, is formed of plywood or the like to a predetermined size.

In this embodiment, the floor 1 is, for example, 1,200×2.40
The floor 1 is formed into a rectangular shape of approximately 0.0 mm, and may be made of any material, but an elastic plate made of synthetic rubber or the like is placed on the upper surface of the floor 1, if necessary, and integrated with the carpet.

As is clear from FIG. 1, this floor 1 has several connecting plates 2 attached at predetermined intervals to one side edge in the width direction, for example.

The connecting plate 2 is formed into a single plate shape from a metal plate or the like, and is rotatably supported on the floor 1 via a shaft 3.

The mounting position of the shaft 30 exists at a position eccentric from the axis of the connecting plate 2, and by rotating the connecting plate 2, it can be disposed astride an adjacent floor surface.

Of course, the connecting plate 2 may not be rotated, but may be made to sufficiently protrude from the side edge of the floor toward the adjacent floor 1 in advance.

Further, a rotating plate 4 is rotatably supported at one end via a shaft 5 on the side line of the floor 1 on which the connecting plate 2 is attached and near both ends thereof.

The rotating plate 4 is formed into a rectangular plate shape from a metal plate or the like, and has a notch 4a formed at one side edge of its free end.

On the other hand, a connecting plate 6 is fixed to the lower surface of the side edge of the floor 1 on the side where the connecting plate 2 and the rotating plate 4 are attached, in a state where it is fastened together with, for example, two connecting plates 2. .

This connecting plate 6 is formed into an elongated plate shape from a metal plate or the like, and its installation is as shown in FIGS. 1 and 1.

As is clear from Figure 2, it protrudes outward by 4 degrees of its width.

As is clear from FIG. 1, the connecting plate 6 is also accommodated and swung on the side adjacent to the side to which the connecting plate 2 etc. are fixed.

On the upper surface of the floor 1 and on the side edge opposite to the side edge to which the connecting plate 2 etc. are attached, there is a pin into which the notch 4a of the rotary plate 4 is fitted at a position opposite to the rotary plate 4. 4b is planted.

On the other hand, on the back surface of the floor 1, as shown in FIGS. 2 and 3, a large number of elastic support members T are fixed at predetermined intervals vertically and horizontally.

As shown in an enlarged view in FIG. 4, the elastic support member 1 includes a seat 9 fixed to the floor 1 by screws 8, a coil spring 10, and a receiver added to the lower end of the coil spring 10. It consists of a tool 11.

The seat 9 is formed into a disk shape and is fixed to the floor 1 with screws 8, and has a boss 9a in the center that is fitted into the floor 1 through a through hole. A hole is formed in the boss 9a.

An h-screw 12 is screwed into the h-hole of the boss 9a, and a plate t-113 supporting the upper end of the coil h1017) is also tightened by this h-screw 12.

The upper end of the coil b1O is supported by the plate h13 and fixed to the seat 9 by the h 12, and the lower end thereof is in contact with the permanent floor surfaces 1 and 4 of a gymnasium, for example, via the support 11. ing.

The receiver 11 is molded from a metal plate having a cup-shaped cross section, but it may also be molded from other materials such as synthetic rubber or urtan rubber, and molded integrally with the lower end of the coil batt 110.

Therefore, even if a large load is applied to the floor surface, the presence of the support 11 creates a large frictional force against the floor surface 14, so the lower end of the coil #210 is hardly displaced and is applied to the floor. Load can be absorbed reliably.

In addition, if the elasticity of the coil batalo becomes weak after long-term use and you want to replace it, or if the purpose of the gymnasium itself is limited to a judo hall, kendo hall, or a training ground for wrestling, ball games, etc. It is necessary to change the elasticity of the coil batalO if desired.

In such a case, the coil plate hlo can be replaced very easily with a separate part by simply removing the hji 12 and the plate h13, and the separate part is attached to the catch seat 9 by the hji 12 and the plate ta13. can be fixed at the same position.

Therefore, the support member T, which is constructed around the coil batt t-110, has a structure that can be attached to and removed from the floor 1 at any time at the same position due to the presence of the seat 9.

To explain this a little more, if the screw 12 is screwed directly into the plywood floor 1 without using the strike plate 9, when replacing the coil #210, the screw 12 must be unscrewed again. When screwing on, the h hole becomes so-called stupid, and you can't screw hji 12 in the same place, but you have to screw it in a different place, and the installation position of the coil bar hlo changes and becomes uneven. However, if the metal catch seat 9 is used, the catch seat always remains fixed to the floor 1, and the screw 12 can be unscrewed and screwed in the same place as many times as desired. It does not have the drawbacks mentioned above.

Although the embodiments have been described above, according to the present invention, as an elastic support member that supports the floor of a gymnasium where a large load is applied, a structure is adopted that allows it to be removably housed in the same position on the back of the floor. , unlike in the past, when the elastic support member is used for light exchange, its attachment can be freely replaced depending on the purpose of use without changing the location. It can be attached to the seat by a method such as mechanical caulking without using means such as welding, and can be extremely easily fixed even to a seat made of a different material.
