Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a waterproof door device for closing an entrance to a building during a flood.

[Prior art]

As is well known, many waterproof door devices are of the swing type or horizontal pull type.

In a normal building, the entrance opening of a swing-type device is narrower than the width (frontage) of the room, and it can only swing 90 degrees. It gets in the way of space usage and is also unsightly.

In addition, in order to fully open the waterproof door, the side-pull type device requires that the length of the storage space (the retractable door bag space) be longer than the full length of the waterproof door, and there are restrictions on where the device can be installed, making it unavoidably dangerous. In addition, methods such as a removable and transportable type are used, which are difficult to operate.

[Problem that the invention seeks to solve]

The present invention aims to provide a watertight door device that overcomes the drawbacks of the conventional device described above by employing a new device that is capable of turning and pulling sideways.

[Means for solving problems]

That is, the present invention provides a guide rail at the upper part of the wall surface on one side of the opening to be closed, attaches the upper part of one side of the waterproof door to a hanging wheel running on the upper guide rail via a lifting device, and attaches the lower part to the lower guide rail. The waterproof door is slidably engaged with the waterproof door, and a running wheel projects from the lower part of the free end side of the waterproof door, and a recess into which the running wheel fits is provided on the ground at the closed position of the waterproof door.

Embodiments of the present invention will be described below based on the drawings.

〔Example〕

Fig. 1 is a plan view of an embodiment of the present invention, and Fig. 2 is a front view thereof, in which 1 is a curtain rail type upper guide rail provided at the upper part of the left side wall of the opening to be closed 2, and 3 is an upper guide rail provided at the lower part thereof. The lower guide rail 4 is a waterproof door whose left upper part is rotatably attached to a hanging wheel 6 running inside the upper guide rail 1 via a screw type lifting device 5.

At the left end of this waterproof door 4, a downwardly protruding
A pin 8 (see FIGS. 4 to 6) engaged with the guide groove 7 of the lower guide rail 3 is provided, and a running wheel 9 (see FIG. 3) projecting downward is provided on the rear surface of the lower right side. A watertight rubber piece 10 is attached to the lower surface.

Reference numerals 11 and 12 indicate recesses provided at the closed and open storage positions of the waterproof door 4, and 13 indicates a cursor that penetrates the pin 8 and engages with engagement portions 14 and 15 provided at both ends of the upper portion of the lower guide rail 3. Protrusions 16, 16 are provided at both ends of the lower surface to fit into the guide groove 7 of the lower guide rail 3, or to engage with the outside of the lower guide rail 3.

In the figure, 18 is a stop pin.

Next, the opening/closing operation will be explained. When the door is in the closed state as shown in FIGS. Raise the left side,
Then, as shown in FIG. 1, it is turned in the direction a.

With this operation, the pin 8 that was engaged with the engaging portion 14 of the lower guide rail 3 via the cursor 13
As shown in FIG. 3, the recess 11
The running wheel 9 that was inside comes out to the ground, and the watertight rubber 1
1 leaves the ground. Therefore, the waterproof door 4 can be easily turned. After turning 90 degrees, manually switch the cursor 13 from the turning position to the running position (rotate 90 degrees) and push it to the left to easily open the storage area. 1
7 can be stored. At this time, the cursor 13 automatically fits into the engaging portion 15, and the traveling wheel 9
falls into the recess, and the waterproof door 4 is locked in the retracted position.

In this case, as can be seen from Figures 1 and 2, the running wheels 9 are located on the right side, so unless an earthquake or special impact is applied, the waterproof door 4 will remain on the traffic side even if it is tilted toward the wall. It is safe and does not tilt.

If you want to close it, just do the above operation in reverse.

[Different embodiments]

In the embodiment, a screw-type lifting device is illustrated, but it is needless to say that the lifting device is not limited to a screw-type lifting device. Further, in the embodiment, the cursor 13 is free, but it can also be fixed to the pin 8.

〔Effect of the invention〕

As described above, the device of the present invention has the disadvantages that the conventional device cannot store the side-swing type waterproof door due to lack of storage space, and the swing type waterproof door becomes a hindrance to the use of room space when opened. It is suitable as a waterproof door device because it solves all the drawbacks at once and can be easily opened, closed, and locked by raising and lowering only one side.
