2. Description of the Related Art Conventionally, in a fire hydrant device using a shape-retaining hose installed on a wall surface, a drum A having an opening A'as shown in FIG. There was something to use. Such a drum type fire hydrant device has been frequently used in recent years because of its simple structure and low cost. The drum type fire hydrant device is used by winding the fire hose 3 from the inner side of the outer peripheral wall of the drum A toward the center side and storing it. At the time of fire extinguishing, the on-off valve of the fire hydrant is opened and Fire extinguishing activities are carried out by successively feeding out the fire hose 3 from the opening.

[0003]

In the conventional drum type fire hydrant device, the fire hose 3 is successively fed out from the opening A'in the center of the front surface of the drum A as described above. At this time, the fire hose 3 is used. The fire fighting hose 3 positioned below the opening A ′ must climb over the lower edge of the opening A ′ when unwound from the opening A ′. However, since the fire hose 3 is filled with water and the fire hose 3 in the drum A is tightly wound in a narrow space, as shown in FIG. The lower edge of the opening A ′ is crossed over at a steep angle, and as a result, resistance is generated when the fire hose 3 crosses the lower edge of the opening A ′, and a large force is required depending on the pulling direction. There is also. However, since it is a general person who generally uses a fire hydrant device in the event of a fire and training is not sufficient, it is not desirable for the fire hose 3 to be able to be delivered smoothly, and there may be cases in which disaster prevention is ineffective. To be

On the contrary, since the fire hose 3 located above the opening A'will fall due to gravity, the opening A'can be smoothly moved even if the position of the opening A'is slightly displaced. You can get out from

Therefore, an object of the present invention is to provide a fire hydrant device having a hose housing capable of smoothly feeding out a fire hose located below the opening from the opening.

[0006]

In order to achieve the above object, in the fire hydrant apparatus according to the present invention, a hose housing having an outer wall around which a fire hose is wound and an opening on the front is installed in the front of the storage box. In the fire hydrant device, the opening of the hose housing is provided at a position eccentric downward from the center of the hose housing.

Alternatively, in a fire hydrant device in which a hose housing including a support frame for supporting a fire hose in a wound state and a ring-shaped opening provided in the front of the support frame is installed in the front of the storage box, the opening is provided. Is provided at a position eccentric downward from the center of the hose container.

Further, it is desirable that the lower edge of the opening is substantially aligned with the lower edge of the housing.

[0009]

In the fire hydrant device having the above-mentioned structure, the fire hose is usually stored in a wound state inside the hose housing. And when unwinding the fire hose when extinguishing the fire,
The height of the fire-fighting hose located below the hose container exceeds the lower edge of the opening and becomes low.

A drum-shaped hose container is also used as a hose container having a support frame for supporting a wound fire hose and a ring-shaped opening provided on the front surface of the support frame. In the same manner as described above, when the fire-fighting hose is unwound during fire extinguishing, the height of the fire-fighting hose located below the hose container exceeds the lower edge of the opening and becomes low.

If the lower edge of the opening is made to substantially coincide with the lower edge of the storage section, the fire hose located below the hose storage body is located below the opening when the fire hose is drawn out when extinguishing a fire. It will not cross the edge.

The manner of use of the fire hydrant device having such a configuration will be described below. First, in a normal state, the fire-fighting hose 3 is wound on the inner surface of the outer peripheral wall 2a of the hose housing 2 from the outside to the inside. When a fire occurs, the open / close valve 4 is opened and the fire hose 3 is attached to the opening 2 of the hose housing 2.
From b, the nozzle 3a is pulled out to the fire extinguishing target, and water is discharged.

As described above, in the fire hydrant apparatus according to the first embodiment, since the opening 2b of the hose housing 2 is provided at a position eccentric downward from the center of the front surface of the drum-shaped hose housing 3, the opening 2b is formed. The lower edge of the fire hose 3 approaches the portion located below the fire hose 3. As a result, when the fire hose 3 is unwound from the opening 2b of the hose housing 2 as described above, the height of the fire hose 3 located below the hose housing 2 exceeds the lower edge of the opening 2b. As shown in FIG. 4, the angle at which the fire fighting hose 3 crosses the lower edge of the opening 2b is relaxed, and the fire hose 3 smoothly crosses the lower edge of the opening 2b and passes through. .

On the other hand, the fire fighting hose 3 located above the hose housing 2 stops upward due to the elastic force of the fire fighting hose 3, but since it is filled with water, the force of moving downward due to its own weight increases. Even if the upper edge of the opening 2b shifts downward, there is no problem because the fire hose 3 located above the hose housing 2 easily passes through the upper edge of the opening 2b.

Since the fire hose 3 is stored in the hose housing 2 in a wound state, the fire hose 3 passes through the opening 2b of the hose housing 2 in a circle. In the example, the opening 2b has a circular shape corresponding to this. However, if the resistance when the fire-fighting hose 3 located below the hose housing 2 crosses the lower edge of the opening 2b is focused on as described above, as shown in FIG. 2b may be widened so that the lower edge substantially matches the lower edge of the storage portion. By doing this, the hose housing 2
Therefore, the fire hose 3 located below will be easily extended from the opening 2b without being hindered by the lower edge of the opening 2b.

(Embodiment 2) FIG. 6 shows another embodiment of the present invention. The fire hydrant device according to the second embodiment includes a storage box 1,
Hose housing 2'fixed to the inner front surface of the storage box 1
And a fire-fighting hose 3 having a nozzle 3a at its tip supported in a wound state inside the hose housing 2 ', and an on-off valve 4 connected to one end of the fire-fighting hose 3 where the nozzle 3a is not provided. It is composed of and.

The hose housing 2'includes a support frame 2c 'for supporting the wound fire hose 3, a ring-shaped opening 2b' provided on the front surface of the support frame 2c ', and the opening 2b'. It is constituted by an openable / closable pressing frame 2d 'provided at the edge, and the opening 2b' is provided at a position eccentric downward from the center of the hose housing 2 '.

The manner of use of the fire hydrant device having such a configuration will be described below. First, in order to store the fire hose 3 in the hose container 2 ', the fire hose 3 is pre-rolled, and the holding frame 2d' of the hose container 2'is opened to open the fire hose. 3 is put into the support frame 2c 'and is supported by this support frame 2c'. Then, the holding frame 2d 'is closed to complete the storage. Then, when a fire occurs, the fire hose 3 is drawn out from the opening 2b ′ of the hose housing 2 ′ and the nozzle 3a is drawn out to the fire extinguishing target to perform the fire extinguishing activity, as in the first embodiment.

Also in the fire hydrant apparatus according to the second embodiment, since the opening 2b 'of the hose housing 2'is provided at a position eccentric downward from the center of the front surface of the support frame 2c', the lower edge of the opening 2b 'is wound. Approach the portion located below the stored fire hose and insert the fire hose 3 into the opening 2 of the hose housing 2 '.
When unwinding from b ′, the height of the fire hose 3 located below the hose container 2 ′ exceeds the lower edge of the opening 2b ′, and the height of the fire hose 3 falls below the opening 2b ′. You will get over the edge smoothly.

Also in the second embodiment, the opening 2b 'is formed.
Although it is circular, as in the case of the first embodiment, as shown in FIG. 7, the opening 2b ′ may be widened so that the lower edge substantially matches the lower edge of the storage section. In this way, the first embodiment
In the same manner as in the above case, the fire hose 3 located below the hose housing 2'is not caught on the lower edge of the opening 2b '.

[0023]

The present invention has the following effects due to the above configuration. First, since the height of the fire hose located below the hose container exceeds the lower edge of the opening, the height of the fire hose located below the hose container easily crosses the lower edge of the opening and catches. There is no.

Even when the drum-shaped hose container is used as the support frame, the action of pulling out the fire hose is the same. Therefore, as described above, the fire hose located below the hose container has the opening lower edge. The fire hose can be smoothly fed out from the opening by easily overcoming.

If the lower edge of the opening is made to substantially coincide with the lower edge of the storage section, the fire hose located below the hose housing is located below the opening when the fire hose is drawn out during fire extinguishing. It is possible to more reliably prevent the fire hose from catching on the edge and being caught on the lower edge of the opening.
