Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding up-and-down type waterproof door which is raised and lowered by new raising and lowering means.

[0002]

2. Description of the Related Art Waterproof doors for preventing flooding are provided at entrances and roads of buildings, basements, etc., which are expected to be flooded by heavy rain, and the type of waterproof door is mainly a plug-in type. , A sliding type and an undulating type.

[0003] Of these, the undulating type is often installed at a place where aesthetics are required to be maintained, such as a building entrance, so that the undulation of the waterproof door is performed using an air cylinder or an oil cylinder, or a gear device. Are used.

[0004] However, in the case of using this type of mechanical undulating device, the construction depth of the floor for storing the waterproof door must be deep due to the structure of the undulating device, and fine adjustment of the mounting position is required. There is a problem in that, in the case of failure, the repair requires cost and labor, and causes pollution such as oil leakage.

[0005]

Accordingly, the present invention requires only a shallow construction depth of the floor surface, does not require fine adjustment for installation of the apparatus, and is not only easy to repair but also reduces pollution such as oil leakage. An object of the present invention is to provide a sliding undulating waterproof door that does not occur.

[0006]

The present invention has solved the above-mentioned problems by using a hose-shaped intake inflatable body as a means for raising and lowering a waterproof door.

That is, according to the present invention, a vertical roller guide and a rising door contact are provided on both sides of a front portion of a storage portion, and a horizontal roller guide is provided on both inner sides. A waterproof door to be stored in the storage part, a rear part of the waterproof door pivotally connected to a parallel moving member, and a suitable number of bent connecting rods having both ends attached to the parallel moving member and the rear part of the storage part; And a rear roller that engages with the roller guide provided in the lateral direction is provided on both sides of the rear end of the waterproof door and on the axis of the pivoting portion of the parallel moving member, and the roller provided in the vertical direction is provided. A front roller engaged with the guide is provided on both front sides of the waterproof door so as to be biased upward from a mounting position of the rear roller,
Compressed air is supplied to the hose-shaped bent body, and the waterproof door is slid upright by the expansion force of the hose-like bent body, and the compressed door is discharged to fall down.

1 to 5 show one embodiment of the present invention. FIG. 1 is a plan view when stored, FIG. 2 is a plan view when standing up, and FIG. 3 is a cross-sectional view when stored. , FIG. 4 is a sectional view at the time of standing,
FIG. 5 is a diagram showing the structure of the roller guide and the positional relationship between the rear roller and the front roller.

1 to 5, reference numeral 1 denotes a storage box buried on the floor, reference numerals 2 and 2 denote vertical roller guides provided on both sides of a front portion, reference numerals 3 and 3 denote rising door contacts, and reference numerals 4 and 4 denote storage. Lateral roller guides 5 provided on both sides inside the box 1 are guided by the roller guides 2, 2, 4, and 4, and are usually stored in the storage box 1. A translation member pivotally connected via 7,7,8,8
The rear end of the storage box 1 and both ends of the parallel movement member 6 are connected to the rear end of the storage box 1 and connected to the compressor 11 via the pneumatic pipe 12. Hose-shaped bent bodies 13, 13 are engaged with lateral roller guides 4, 4 provided on both sides of the waterproof door 5 on the axis X of the rear part of the waterproof door 5 and the pivot portion of the parallel moving member 6. The rear rollers 14, 14 engage with roller guides 2, 2 provided in a vertical direction as shown in FIG. Front rollers provided on both sides, 15 is a protective cover of the hose-shaped bent body 10 pivotally connected at both ends to the rear of the storage box 1 and the parallel moving member 6, 16 is an exhaust valve, 17 is a drive unit cover, and 18 is a waterproof door. Reference numeral 19 denotes a waterproof rubber attached to the waterproof door 5 and a base 19 of the waterproof door 5.

Next, the undulating operation of the waterproof door 5 will be described.
In FIG. 3, when the compressor 11 is started, compressed air is injected into the hose-shaped bent body 10 through the air supply pipe 12, and the waterproof door 5 is pushed out by expansion and expansion.

Then, as described above, the front rollers 14, 14 provided on both front sides of the waterproof door 5 are deflected upward from the rear rollers 13, 13 provided on both rear sides as shown in FIG. Since it is provided, the front part of the waterproof door 5 rises as shown in (a) → (b) → (c) of FIG. 6 and finally stands up as shown in (d).

In the embodiment, the inner width of the longitudinal roller guide 2 is made larger than the outer diameter of the front roller 14 so that the roller guide 2 can easily be raised. The moving guide 20 is provided, and the waterproof rubber 19 provided on the waterproof door 5 is configured to be pressed against the rising door contacts 3, 3.

When the waterproof door 5 is to be stored, the exhaust valve 17 shown in FIG. 3 is opened and a small amount of air is exhausted.
In the above, the guide 20 is moved in the direction of the arrow with a hammer.
So that the roller 14 comes to a position below the waterproof door 5
And then exhaust valve 16 is fully opened. Then, the waterproof door 5 descends by its own weight and is stored in the storage box 1. Instead of a simple structure of moving with a hammer, as shown in FIGS. 7 and 8, a device for moving and bending the bending connection rods 8, 8 in the direction of the arrow with the handle 21 may be provided.

[0014]

1) The hose-shaped bent body 10 is always in the storage box 1 and the waterproof rubber 18 is also in the storage box 1 when stored, and is concealed by the waterproof door 5 when stored. The waterproof rubber is not exposed as in the ups and downs type, so the appearance is not spoiled.

2) Since air pressure is used as the drive source, there is no pollution such as oil leakage.

3) The pneumatic hose-shaped bent body 10 used as a drive source can reduce the storage space as compared with a mechanical actuator.

4) Since the hose-shaped bent body 10 has water resistance, it is possible to cope with a type in which the driving device is disposed on the immersion side.

5) When the shape of the waterproof door 5 becomes large or the weight increases, it can be dealt with by increasing the number of hose-shaped bent bodies.

6) When standing up, the finished surface of the door faces the outside,
The drive unit does not appear on the floor, so its appearance is good.
