[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a building having a large floor area, for example, a hose reel type fire hydrant device which is installed on a floor surface at a substantially central position in a room such as a supermarket or a department store and used for fire fighting activities. Regarding

[0002]

2. Description of the Related Art Generally, a hose reel type fire hydrant device is widely used as a fire hydrant device installed in buildings such as supermarkets and department stores. That is, in the fire hydrant device, a hose reel around which a hose is wound is rotatably disposed in a fire hydrant box installed on the wall surface of a building, and the base end of the hose is connected to a fire hydrant valve and the tip of the hose is connected. When the nozzle and the tip of the hose are pulled and pulled, the hose is quickly withdrawn by the rotation of the hose reel.

By the way, since the conventional fire hydrant device is installed on the wall surface of a building, the area where the hose can be pulled out is limited to a range of 180 degrees at the maximum, and the length of the hose is also limited by the size of the hose reel. It had been. For that reason,
The fire hydrant device installed on the wall is extremely limited in the area where fire fighting activities can be performed, and in a building with a large floor area, only one fire hydrant device cannot cover the entire room, and the fire hydrant device can be installed in several places on the wall. Had to set up.
As a result, it takes time to install the fire hydrant device,
There was a problem of causing a sharp rise in equipment costs.

Therefore, the applicant of the present invention has previously developed a fire hydrant device that solves the above-mentioned problems, and has developed the fire hydrant device 4-5.
It is open to the public as 5361. That is, in the fire hydrant device, a fire hydrant box containing a hose reel and a hose and the like is installed in an embedded state on the floor at a substantially central position in the room, and the hose in the fire hydrant box can be pulled out from the floor. As a result, the hose can be pulled out in any direction of 360 degrees during fire fighting activities, and the area where fire fighting activities can be performed is greatly expanded, so that even a building with a large floor area can cover the entire room with one fire hydrant device. It has become.

[0005]

However, the fire hydrant device still has a problem to be solved. That is, since the fire hydrant box is embedded in the floor so that it is at the same level as the floor surface, when pulling out the hose from the opening of the fire hydrant box, the hose may come into contact with the peripheral edge of the opening of the fire hydrant box depending on the direction of pulling out the hose. There is a problem in that the hose cannot be pulled out smoothly and smoothly because it is greatly bent or is caught on the peripheral edge of the opening of the fire hydrant box.
Also, since the entire device is located below the floor surface, the operator must bend forward when using the fire hydrant device in a cramped position, which is inferior in operability and handleability. There was a problem called.

The present invention was created in order to solve the above-mentioned problems, and its purpose is to make a hose stretch and take-up smooth and smooth, and to provide a fire hydrant excellent in operability and handleability. To provide the equipment.

In order to achieve the above object, the fire hydrant device of the present invention is provided with a box-shaped main body and an opening of the main body which are installed on the floor surface at a substantially central position in the room and whose upper side is opened. A fire hydrant box consisting of a box-shaped lid that opens and closes downward, a hose reel rotatably disposed in a horizontal position inside the fire hydrant box and above the upper end of the main body, a hose reel or a fire hydrant box. A fire hydrant valve disposed inside the hydrant, connected to a high-pressure water source, and a hose wound around a hose reel, having a proximal end connected to the hydrant valve and a nozzle connected to the tip. . Further, it is preferable to provide the hose reel with a hose disorder prevention mechanism for preventing the hose from sagging or disturbing when the hose is stretched or wound.

[0008]

When the operator opens the cover of the fire hydrant box in the event of a fire, the hose reel is completely opened and the hose can be pulled out from the hose reel. After that, when the operator opens the fire hydrant valve and holds the nozzle and the tip of the hose and pulls in the direction of fire, the hose reel rotates in the direction of feeding the hose, and the hose is sequentially pulled out from the hose reel. At this time, the hose reel is horizontally rotatably supported at a position projecting upward from the main body of the fire hydrant box, and the periphery is completely opened.
No matter which direction the hose is pulled, the hose does not get caught in the fire hydrant box or the like and is not bent significantly, and the hose can be pulled out smoothly and smoothly. In addition, since the hose disorder prevention mechanism equipped with rollers is installed on the hose reel, even if the hose reel rotates too fast than the withdrawal speed of the hose and the hose tries to unwind from the hose reel, the hose disorder prevention mechanism Roller presses the hose. As a result, the hose can be prevented from sagging or disturbing, and the hose can be stretched more favorably and smoothly. Then, when the hose is extended to the vicinity of the fire position, water is sprayed from the nozzle to extinguish the fire. On the other hand, after the fire extinguishing work, the fire hydrant valve is closed, the hose reel is rotated in the hose winding direction, and the hose is wound on the hose reel. At this time, the hose is guided by the rollers of the hose disorder prevention mechanism and is wound up on the hose reel in an orderly manner.
In this fire hydrant device, the hose reel etc. are arranged at the height level that is integrated from the floor surface, so the operator can open and close the fire hydrant valve and wind the hose on the hose reel without taking a cramped posture. And so on. As a result, opening / closing operation of the fire hydrant valve and winding of the hose can be performed easily and easily, and operability and handleability are excellent.
