Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire hydrant device installed in a tunnel or the like and used for extinguishing a vehicle fire.

[0002]

2. Description of the Related Art Conventionally, as a fire hydrant device installed in a tunnel such as a highway or a road dedicated to automobiles, for example, FIG.
Are known (Japanese Patent Laid-Open No. 2001-9594).
0 etc.).

In this fire hydrant apparatus 100, a hose 103 having a nozzle 102 is housed in a housing, and in a fire, the door 101 is opened and the hose 103 is pulled out by holding the nozzle 102 to extinguish the fire. In order to prevent the hose 103 from coming out more than necessary when pulling out this hose,
A hose guide 104 is provided inside the door 101, and the hose 103 is pulled out through the hose guide 104.

[0004]

However, in such a fire hydrant apparatus having a hose guide inside the door, the hose movement is restricted by the hose guide. There is a problem in that it hinders the rewinding into the body, and it takes time and labor to store the hose in the inwardly wound state.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fire hydrant device in which the hose can be easily rewound into the inner wound state.

[0006]

To achieve this object, the present invention is constructed as follows. The present invention relates to a fire hydrant device for accommodating a hose with a nozzle wound inside a housing and opening the door of the housing to pull out the hose with a nozzle to extinguish a fire when a fire is extinguished. And a detaching structure capable of switching the hose guide from the hose insertion position to the hose non-insertion position.

Therefore, according to the present invention, when the hose is rewound inward after the fire is extinguished, the hose guide is removed from the hose so that the hose can be unwound easily and easily without being hindered by the hose guide. Becomes

Here, the hose guide is, for example, an inverted U-shaped arm member, one end of which is rotatably mounted on the door side, and the other end of which is detachably supported on the door side. The other end of the inverted U-shaped arm member can be attached to and detached from the door side by a structure in which a rotating frame is fastened to a fixed frame via a hinge, a structure in which an arm end is locked by a stopper pin, and an arm end. Or a structure in which a screw portion is formed in each of the arm end portion and the door-side fixing portion and is fastened with a nut ring.

The hose guide is an inverted U-shaped arm member, and both ends may be detachably supported on the door side. In this case, as a structure for attaching and detaching the inverted U-shaped arm member to both door sides, a structure in which the arm end portion is locked by a stopper pin, a structure in which the arm end portion is screwed and fixed to the door side, etc.

The hose guide may be a member in which an arm is attached to the ring, and the arm may be detachably supported by a screw portion fixed to the door side.

In the third embodiment, as shown in FIG. 9A, the same stoppers 24 as those in the second embodiment of FIG. 8 are provided to the arm ends on both sides of the inverted U-shaped guide arm 20. There is.

The stopper 24 has the same structure as that of the second embodiment of FIG. 8 shown in FIG. 9B. However, the structure is not limited to the cutout structure, and may be an inner hole structure. For this reason, when returning the hose to the inward winding state after extinguishing the fire, the lever 26 provided on the stopper 24 is retracted to release the lock of the guide arm 20 by the pin 25, whereby the guide arm 20 is removed from the fire hydrant door 4. By removing the hose, the work can be easily performed without hindering the rewinding of the hose.

FIG. 10 is an explanatory view of a fourth embodiment of the hose guide of the fire hydrant apparatus of the present invention. In the hose guide 15, the mounting bracket 30 is fixed to each of both arm ends of the guide arm 20 formed in an inverted U shape,
The mounting brackets 30 are detachably provided inside the fire hydrant door 4 by fixing screws 31.

For this reason, when the hose is returned to the inward winding state after extinguishing the fire, the guide screw 20 is removed from the fire hydrant door 4 by removing the fixing screw 31 as shown in the figure, and the hose guide 15 is not hindered by the hose guide 15. The rewinding work to the wound state can be easily performed.

In the fourth embodiment of FIG. 10, the mounting brackets 30 are fixed to both arm ends of the guide arm 20 and can be attached to and detached from the fire hydrant door 4 with the fixing screws 31, but the mounting brackets 30 can be attached to the fire hydrant. It is fixed to the inside of the door 4, and both arm ends of the guide arm 20 are fitted into this, and the fixing screw 31 is screwed in from the side of the mounting bracket 30, and fixed.
To remove, loosen the fixing screw 31 and attach the door side mounting bracket 30.
However, only the guide arm 20 may be removed.
Further, it may be fixed by screwing it in, or by inserting a screw.

FIG. 11 is an explanatory view of the fifth embodiment of the hose guide in the fire hydrant apparatus of the present invention. In the hose guide 15 of the fifth embodiment, the right arm end of the guide arm 20 formed in the inverted U shape is shown in FIG.
Similar to the first embodiment, the rotary mounting member 18 is rotatably mounted inside the fire hydrant door 4.

The left arm end of the guide arm 20 is cut midway, and a screw portion 20a is formed in this portion. A fixed arm 41 is fixed to the door side of the guide arm 20 on the screw portion 20a side, and a screw portion 41a is also formed at the tip of the fixed arm 41. This guide arm 2
0 side screw part 20a and fixed arm 41 side screw part 41a
For, the nut ring 40 is screwed on.

In the fixed state of the guide arm 20 of FIG. 11A, the nut ring 40 is fixed to the fire hydrant door 4 by screwing both the screw portion 20a and the screw portion 41a. When returning the hose to the inward winding state after extinguishing the fire, turn the nut ring 40 and screw the nut ring 40 into the screw portion 41a of the fixed arm 41 as shown in FIG.
Remove from the screw portion 20a on the guide arm 20 side.

As a result, the left side of the guide arm 20 is free, and the guide arm 2 is centered around the rotary mounting member 18.
It can be removed from the hose by rotating 0 to the outside, and the rewinding operation of the hose to the inner winding state can be easily performed.

FIG. 12 is an explanatory view of the sixth embodiment of the hose guide of the present invention. In the hose guide 15 of the sixth embodiment, as shown in FIG. 12 (A), an arm 32a is integrally formed with a guide ring 32, and the arm 32a is attached to a mounting bracket 33 provided inside the fire hydrant door 4. ing.

The fitting 33 has the structure shown in FIG. That is, the holding frame 35 is provided separately from the fixed frame 34 fixed to the fire hydrant door 4 side, and by attaching the screw 36 and the nut 38 to the fixed frame 34, as shown in FIG.
As described above, the guide ring 32 is fixed to the inside of the fire hydrant door 4.

When the hose is returned to the inward winding state after extinguishing the fire, the nut 38 is removed as shown in FIG.
5 is separated from the fixed frame 34. As a result, the guide ring 32, which was supported by the mounting bracket 33, is not attached to the fire hydrant door 4.
The hose guide 15 is detached from the fire hydrant door 4 to be in a free state, so that the hose can be easily returned to the inward winding state.

The detachable mechanism structure of the hose guide of the present invention is not limited to the above-mentioned first to sixth embodiments, and one side of the guide arm having an inverted U-shape with respect to the door is removed to rotate. An appropriate detachable mounting structure can be used as long as it has a structure for removing the arm ends of the guide arm.

[0047]

As described above, according to the present invention, when the hose is rewound to the inner winding state after the fire is extinguished, the withdrawal amount is restricted by passing the hose inside the fire hydrant door. Since the hose guide can be moved to a position separated from the hose, the hose is not obstructed by the hose guide, and the work time required for hose storage work can be shortened and labor can be saved.

Further, since the hose can be stored without being restricted by the hose guide, the hose can be stored easily, and the hose can be properly wound in the inner winding state. As a result, the hose can be reliably pulled out in case of fire. You can
