Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a side-swing type waterproof door device for closing the entrance and exit of a building during a flood.

[Prior art]

As is well known, at the lower edge of the waterproof door of the waterproof door device,
Elastic packing is installed to make it watertight.

Therefore, in the case of a horizontal pull type, since the friction is so large that it cannot be pulled sideways as it is, a wheel protruding device for raising the door is provided, which causes the retraction wheels provided at both ends to protrude downward when the door is pulled sideways. Commonly used methods include wheels at both ends, parallel wheels to prevent the door from tipping over, and a frame to prevent the door from tipping over.

In order to prevent it from falling over, wheels are usually provided or a fall prevention frame is provided.

[Problem that the invention seeks to solve]

The conventional horizontal pull type waterproof door device with wheels at both ends is
As mentioned above, when moving the waterproof door, the wheels installed at both ends had to be operated, which was time-consuming.
The present invention seeks to provide something that can be quickly moved, set up, and stored.

[Means for solving problems]

That is, in the present invention, an upper guide rail is provided on the upper part of the wall surface on one side of the opening to be closed, and an elevator guide rail that is moved up and down by an elevating device is provided at the end on the side of the opening to be closed. The upper part of one side of the waterproof door is connected to a hanging wheel running in a guide rail, the running wheel is made to protrude from the lower part of the free end side of the waterproof door, and a recess into which the running wheel fits is formed on the ground at the closed position of the waterproof door. It was established.

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 an elevator guide rail provided at the end on the side of the opening to be closed.

This elevator guide rail 4 is adapted to be raised and lowered by a screw type lifting device 5 fixed to the left side wall, and the upper part of one side of the waterproof door 6 runs inside this elevator guide rail 4 and the upper guide rail 1. It is connected to a hanging wheel 7.

A pin 8 inserted into a guide groove (not shown) of the lower guide rail 3 is provided at the lower left end of the waterproof door 6, a running wheel 9 is provided at the lower part of the free end, and a watertight rubber piece 10 is attached to the lower surface. It is being

Reference numerals 11 and 12 are recesses into which the running wheels 9 provided in the closed position of the waterproof door 6 fit, and the running wheels are in a floating state within the recesses.

Next, the opening/closing operation will be explained. When the elevator is in the closed state as shown in FIGS. 6, and at the same time raise the left side of the waterproof door 6 via the hanging wheel 7.
The running wheels 9 in the recess 11 are brought into contact with the ground to remove the load of the waterproof door 6 from the watertight rubber piece 10, and then moved laterally in the direction a as shown in FIG.

By this operation, as shown in FIG.
The running wheel 9 that was inside comes out to the ground, and the watertight rubber 1
0 is completely off the ground and can be moved lightly, and in this state, by pushing it to the left, it can be easily stored in the storage section 13.

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

[Different embodiments]

In the embodiment described above, a screw type lifting device was used, but a gear device or the like may also be used.

〔Effect of the invention〕

The device of the present invention does not require a wheel protruding device to levitate the waterproof door, parallel wheels to prevent it from falling, or a fall prevention frame like conventional devices, and can be easily opened and closed by lifting and lowering on only one side. Therefore, it is suitable as a horizontally pulling waterproof door device.
