Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-embedded indoor fire hydrant.

[0002]

2. Description of the Related Art Conventionally, a fire hydrant, such as a No. 2 fire hydrant that can be easily operated, has been conventionally installed in a corridor. When a fire is detected, the lever of the fire hydrant valve is tilted down, the hose is pulled to the fire area, and the fire extinguisher nozzle is struck. The fire was extinguished by opening water to release water.

[0003]

However, when a fire is found indoors, etc., it is necessary to once go to the place where the indoor fire hydrant is installed, open the fire hydrant valve, and then return to the fire site again with the fire extinguisher nozzle. It was In addition, indoor fire hydrants are usually installed in corridors, but even people living in the building often do not know where indoor fire hydrants are installed, and people who found a fire during a panic situation could find it. It takes even longer to find an indoor fire hydrant if you are not familiar with the building. In other words, as explained in the above example, it took a very long time to find an indoor fire hydrant when the fire was discovered, and then to reach the fire site with the fire extinguishing nozzle, and there was a fear that a large fire would occur during that time. Further, when a fire occurs on a large area floor such as an exhibition hall or an atrium, the fire extinguishing nozzle may not be located within the fire extinguishing range because the position of the fire hydrant is too far away from the fire place. Therefore, there is a risk that the fire may not be extinguished effectively and may become a large fire.

In view of the above circumstances, an object of the present invention is to enable a fire to be extinguished quickly and effectively in a room, particularly a room having a large floor area.

[0005]

DISCLOSURE OF THE INVENTION The present invention is intended to achieve the above object by accommodating a fire hydrant in a concave accommodation portion of a floor and providing a lid on the accommodation portion.

[0006]

When a fire occurs, the fire extinguisher operator goes to a position with a lid, opens the lid, takes out the fire hydrant, and opens the fire hydrant valve.
Then, while holding the fire extinguishing nozzle and pulling the shape-retaining hose, the nozzle is positioned within the fire extinguishing range distance to extinguish the fire. After the fire extinguishing work is completed, the fire extinguisher worker puts the fire hydrant into the holding portion and closes the lid.

[0007]

Embodiments of the present invention will be described with reference to the accompanying drawings. A recessed accommodating portion 1 is formed by deeply excavating the central portion FC of the floor F of the exhibition hall in the vertical direction, and a lid 2 is provided on the upper surface thereof.
This lid 2 is provided with an indicator lamp for position confirmation, and its surface is flush with the surface of the floor. Although the fire hydrant 5 is accommodated in the recessed accommodating portion 1, the fire hydrant 5
Is a self-winding type retention hose 7 in a vertically long hose box 6.
A fire hydrant valve 8 provided in the hose box 6, a water supply pipe 9 connected to the shape-retaining hose 7, and a gas spring 10 for vertically moving the hose box 6.

Next, the operation of this embodiment will be described. When a fire breaks out, the fire extinguisher searches for the position of the fire hydrant 1, but the lid 2
Since there is an indicator light on the, its position can be easily confirmed. Then, it reaches the position of the lid 2, opens it, and pushes the switch 10a of the gas spring 10. Then, the fire hydrant 1 rises, moves in the direction of arrow A6, and projects onto the floor F as shown by the chain line. Therefore, fire hydrant 1
The state becomes easy for the fire extinguisher to operate. Therefore, the fire-extinguishing operator opens the fire hydrant valve 8, grasps the fire-extinguishing nozzle 12, pulls the shape-retaining hose 7 and heads to the fire area, and positions the fire-extinguishing nozzle 12 within the fire-extinguishing range to perform fire extinguishing. At this time, since the fire hydrant 5 is located in the center of the room, the fire extinguishing nozzle 12 at the tip of the shape retaining hose 7 is a circle centered on the fire hydrant valve 8 and having the entire length of the shape retaining hose 7 as the maximum radius. You can move around.

After completion of the fire extinguishing work, the fire hydrant valve 8 is closed and the upper portion of the fire hydrant 5 is pressed to accommodate the fire hydrant 5 in the concave accommodating portion 1 to restore the original state. Then, when the lid 2 is closed, the surface of the lid 2 and the surface of the floor are located on the same plane, so that the floor surface is smooth without any unevenness. For this reason, the room is easy to use and is in an aesthetically pleasing state.

The embodiment of the present invention is not limited to the above, and for example, instead of forming a recessed accommodating portion by digging a hole in the floor in the vertical direction, the depth may be reduced in the vertical direction as shown in FIG. Moreover, the recessed accommodating portion 21 with the lid 2 may be formed by digging a wide hole in the lateral direction. In this case, the fire hydrant 25 includes a hose 27 with a fire extinguishing nozzle 22 housed in a bare state, a fire hydrant valve 28 connecting the water supply pipe 29 and the hose 27,
It consists of With this configuration, the fire hydrant 25
Since there is no need for means for moving up and down, the cost can be reduced and the fire extinguishing work can be performed more quickly. Of course, the present invention can be implemented not only indoors but also outdoors, for example, in a tunnel.

In the above embodiment, the fire hydrant 5 is usually housed under the floor, and the case where the fire hydrant 5 is used by protruding the fire hydrant 5 by opening the lid 2 at the time of fire has been described. In the case of a place where people enter and leave and the state of the room changes variously in a short period of time, the fire hydrant at the optimum position for extinguishing fire should be projected from the accommodation section onto the floor according to the indoor situation, for example, The fire hydrant 5 in an improper position below the exhibit may be stored in the storage section. In this case, it is advisable to provide a lock mechanism for stably fixing the protruding fire hydrant 5 in the housing portion in the protruding state.

[0012]

Since the present invention is constructed as described above, a fire hydrant can be buried in the floor. Therefore, compared to the case where a fire hydrant is installed in a corner of a room or a corridor, it is possible to accelerate the discharge start time of the fire extinguishing water and expand the fire extinguishing range (range) of the fire extinguishing nozzle, so that a large floor area such as an exhibition hall You can effectively and quickly extinguish fires in your room.
Further, since the fire hydrant is housed in the recessed housing portion and the housing portion is covered, the fire hydrant does not project above the floor surface in normal times. Therefore, since there is no obstacle on the floor surface, the floor can be effectively used.
