Abstract

PROBLEM TO BE SOLVED: To secure a lift stroke even when the interval between an upper floor and a floor foundation bed is narrow by forming a floor face lower than the floor face supported by the first air spring on an intermediate floor, and providing the second air spring on it. SOLUTION: An intermediate floor member 3 is supported on a floor foundation bed 1 via the first air spring 2, and a floor face 3B lower than the floor face 3A supported by the first air spring 2. An upper floor member 5 is supported on the lower floor face 3B via the second air spring 4. Air is fed to or discharged from the air springs 2, 4 via pipes 6, 7 to lift or lower the upper floor member 5. Even when the interval between the upper floor member 5 and the floor foundation bed 1 is made narrow, the lift stroke of the upper floor member 5 is not remarkably limited. Since the air springs 2, 4 are used, this device can be used in the water.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for raising and lowering a floor such as a stage or a pool by using expansion and contraction of an air spring.

[0002]

2. Description of the Related Art As a floor elevating device using an air spring 100, as shown in FIGS. 6 and 7, a plurality of air springs 100 are vertically stacked between a base 101 and a floor member 102. Was. In a state that does not inject air into the air spring 100, the distance between the floor foundation 101 and the floor surface as shown in FIG. 6 is H _1, the interval when injected air lifted floor member 102, FIG. 7 H ₂ (H ₁ <H ₂ )
Met.

[0003]

In the conventional apparatus, a plurality of air springs 100 are provided one above the other.
Can not be lowered the lowest height of 2, i.e., it is not possible to narrow the gap H ₁ of the floor base 101 to the floor, if the installation space of the air spring 100 is small,
If the installation becomes difficult or the installation can be performed, the rising stroke of the floor member 102 must be reduced.

It is therefore an object of the present invention to provide a floor elevating device which secures a certain amount of floor lifting stroke and minimizes the distance from the floor base to the lowest floor.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention supports an intermediate floor material on a floor base via a first air spring, and attaches the intermediate floor material to the intermediate floor material with the first air spring. Forming a floor below the supported floor, and a second floor
The upper floor material is supported via an air spring.

[0006]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0007] In the embodiment shown in FIG.
The intermediate floor 3 is supported via the air spring 2 of the
A floor surface 3B lower than the floor surface 3A supported by the first air spring 2 is formed, and an upper floor member 5 is supported on the lower floor surface 3B via a second air spring 4. The first and second air springs 2 and 4 are connected to pipes 6 and 7 for supplying and discharging air, respectively.

FIG. 2 shows an example in which the apparatus shown in FIG. 1 is applied to the floor of a pool. Only the first air spring 2 is expanded by injecting air to raise the intermediate floor material 3 and the upper floor material 5. It shows the state that it was turned on. A portion of the pipe 7 on the floor base 1 uses a telescopic hose.

FIG. 3 shows a state in which air is injected into the second air spring 4 from the state of FIG. 2 to raise the upper flooring 5. The water depths W ₁ and W ₂ change with the expansion and contraction of the air springs 2 and 4.

[0010] In the pool, the water depth is required to change when used by ordinary adults, when used by infants, or when a disabled person uses a wheelchair. Such a demand can be easily met by using the floor lifting device of the present invention. Further, if the upper flooring material 5 is raised to the water surface, the heat radiation of the hot water can be reduced in the case of the hot water pool.

[0011] Not only when raising and lowering the floor of the pool,
The stage floor can be raised or lowered partially or entirely, or various other floors can be raised and lowered.

The embodiment shown in FIG. 4 shows an example in which two or more intermediate floors 3 are provided, and an air spring 4 'is provided between the intermediate floors 2.

FIG. 5 shows a preferred air spring 10 (2, 4, 4 ') for use in this device. Although the air spring 10 is shown as a bellows type, a diaphragm type air spring may be used.

[0014]

As described above, according to the present invention, the intermediate floor is supported on the floor base via the first air spring, and the floor supported by the first air spring on the intermediate floor is provided. Since a floor surface lower than the floor surface is formed and the upper floor material is supported on the lower floor surface via the second air spring, the distance between the upper floor material and the floor base can be reduced, and Despite the spacing, the lift stroke of the upper flooring is not significantly limited. Also, by using an air spring,
It can be used underwater.
