DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described. FIG. 1 is a front view of a storage case 12 for a fire-extinguishing hose 5 installed in a housing 10 of the fire hydrant device 1, and FIG. 2 is a sectional view of the storage case 12. In the figure,
The fire hydrant device 1 has a fire-extinguishing hose 5 housed in an inner volume.
The fire hydrant device 1 is a so-called inner winding type fire hydrant device, and is installed on an inspection road adjacent to a roadway in a tunnel, for example, or buried in an inner wall of a tunnel. Although not shown in detail, such a fire hydrant device 1 is divided into a fire hydrant storage unit, an electric device unit, and a fire extinguisher storage unit, and has a fire extinguishing nozzle 30 at the tip in the housing 10 in the fire hydrant storage unit. A hose 5 and a storage case 12 for internally storing the hose 5 are provided with a fire extinguishing water supply pipe, a three-way switching valve, a pressure regulating valve, a fire hydrant valve,
It is equipped with fire hydrants for fire brigade.

An opening 12a is provided on the front surface of the storage case 12 for drawing out the hose 5 from the inside and for storing the hose 5 in the storage case 12.
On the front surface of the housing 10, there is provided a forward tilting door 6 whose upper edge side is opened forward with a lower edge that exposes the opening 12 a of the storage case 12 to the outside of the housing 10 as a fulcrum. In addition,
The front tilting door 6 is provided with, for example, a stopper so as to stop at a substantially horizontal position in the open state, and a buffer mechanism is provided to the opening operation by a damper or the like which will not be described in detail. .

The hose 5 is made of a so-called fiber cylindrical woven fabric as a main body, and is formed into a shape-retaining hose having a rubber-lined lining formed inside. Abrasion resistance is imparted and, at the same time, the coefficient of friction is reduced.

The storage case 12 has a box shape with a substantially square outer shape, and has a slightly elongated opening 12a at the center. The hoses 5 are wound in multi-layered multi-rows by using the upper, lower, left and right surfaces, the front and the back of the storage case 12. Rubber contact members 2 and 3 are provided on the upper and lower edges of the opening 12a so as to protrude toward the rear side. When the stored hoses 5 are sequentially drawn out by pulling out the nozzles 30, the contact members 2 and 3 hit the hoses 5 on the left and right sides of the contact members 2 and 3 to reduce the momentum that is drawn out. do. That is, when the hose 5 is pulled out from the inside of the storage case 12, and when the hose 5 comes out from above and below a portion caught in the inner circumference of the storage case 12, the hose 5 is always accelerated and rubbed against the upper and lower peripheral edges of the opening 12 a. Therefore, by providing the contact members 2 and 3 on the upper and lower sides of the peripheral edge, the hose 5 always comes into contact with the contact members 2 and 3 to reduce the momentum. Since the contact members 2 and 3 are made of rubber, they are flexibly deformed, so that the hose 5 is not hooked and cannot be put out.

When the hose 5 is pulled out, the peripheral portion of the opening 12a may not be in contact with the left and right sides, so that even if the contact members are arranged on the left and right sides, it is not expected that a deceleration effect is always obtained. Also, from the situation on the left and right sides, the opening 12a
Even if the shape of the hose 5 is horizontally long, there is an effect that the width of the hose 5 is easy to store when it is stored, regardless of the momentum of the hose 5 at the time of drawing.

When the storage case 12 is compared with the cross section of the housing 10 of the fire hydrant device 1, the height and the thickness of the storage case 12 are substantially equal to the height and the thickness of the housing 10. The dimensional difference between the storage case 12 and the housing 10 is such that, in the thickness, there is room for the opening mechanism of the front tilting door 6 and the like.
In the height, some allowance for electric wiring and the like is provided. As a result, the hose 5 can be housed as thin as possible by using the cross section of the housing 10, and in the storage case 12 of this embodiment, the hose 5 is all housed together with the nozzle 30 at the tip thereof. Therefore, there is no need to provide a space between the storage case 12 and the forward tilting door 6 for preventing the hose 5 from being caught or for holding the nozzle.
Further, the thickness of the housing 10 can be reduced. Further, in this embodiment, since the contact members 2 and 3 are arranged at positions hidden in the storage case 12, there is no problem in aesthetic appearance.

Next, a second embodiment of the present invention will be described. FIG. 3 is a front view of the storage case 21 of the fire hose 5, and FIG. 4 is a cross-sectional view of the storage case 21. The second embodiment is also a so-called inner-winding fire hydrant device in which the fire-extinguishing hose 5 is housed in an inner winding, and is similar to the first embodiment. Therefore, the same reference numerals are given to the same members, and the description thereof will be omitted.

The storage case 21 of the second embodiment also has
Similar to the first embodiment, the outer shape is a box shape having a substantially square shape, and a somewhat horizontally long opening 21a is formed at the center for drawing out the hose 5 from the inside and storing the hose 5 in the storage case 21. Have been. And the opening 21
Rubber contact members 22 and 23 projecting toward the center of the opening 21a are provided on the upper and lower edges of the peripheral edge a. Similar to the first embodiment, when the stored hoses 5 are sequentially fed out, the contact members 22 and 23 have a function of hitting the hoses 5 and reducing the momentum to be fed out. This is because when the stored hose 5 is pulled out, the hose 5 is pulled out forward while being in contact with the upper and lower sides of the opening 21a. Therefore, even in the direction of the contact members 22 and 23, the same as in the first embodiment. The effect is obtained.

Further, a third embodiment of the present invention will be described. FIG. 5 is a front view of a fire-extinguishing hose storage case 31. The third embodiment is also a so-called inner-winding type fire hydrant device in which a fire-extinguishing hose (not shown) is housed in an inner winding. This is the same as the second embodiment. Therefore, the same reference numerals are given to the same members, and the description thereof will be omitted.

The storage case 31 of the third embodiment also has
As in the above embodiments, the outer shape is a box shape having a substantially square shape, and the storage case 31 is formed to be slightly (approximately about 20% in proportion) horizontally long. Accordingly, the height of the fire hydrant device can be reduced, and work such as storage of the hose 5 can be facilitated even when the installation surface is high. Furthermore, in the third embodiment, the tapered surfaces 31b
Are formed. This is because, in order to use the width, height, and depth of the storage case 31 three-dimensionally and efficiently, the hose is pushed into the corners of the storage case 31 and stored, but when the storage case 31 is packed into the lower side, the corner is In some cases, the taper surface 31b is provided in order to prevent this from coming off. Originally, the hose cannot be completely stored in a square shape, and since the corners are curved, forming a tapered surface will assist in efficient storage as well as preventing pushing and there is no space loss be equivalent to. In addition, since the drawing direction of the hose coincides with the falling direction of the hose at the upper corner, it hardly hardens and does not require a tapered surface.

The opening 31a is formed in the center in a horizontally long state. Rubber contact members 32 and 33 projecting toward the back side of the storage case 31 are provided at upper and lower peripheral edges of the opening 31a. As in the above embodiments, when the stored hoses are sequentially fed out, the contact members 32 and 33 have a function of reducing the momentum that the hose hits the left and right sides of the contact members 32 and 33 and is fed out. Is what you do. In addition, a cylindrical contact member 35 is provided at the peripheral portion of the opening 31a, and the contact member 35 is always in contact when the hose (not shown) is pulled out and hits a corner instead of a corner, thereby reducing frictional force. ing.

In each of the above embodiments, the material of the contact member is not limited to rubber, and may be, for example, a plate provided with a spring at the base. I just need. Further, as in the first embodiment, the contact member may be provided only on the upper side, not on both the upper and lower sides of the periphery of the opening. In addition, as for the size, it is only necessary to have strength at the time of contact with the flexibility.However, when forming over the entire width of the upper and lower sides of the opening of the storage case, the hose will only rub, and the contact member will If there is no margin in the difference in width between the upper and lower sides of the opening, the effect of hitting the hose to decelerate where it is accelerating cannot be expected. Therefore, a plurality of abutting members may be provided on one side, since the abutment member is applied to the place where acceleration is performed. Further, it is preferable that the left and right sides of the contact member are substantially perpendicular to the upper and lower sides of the opening.

As described above, according to the first invention, a hose provided with a nozzle is housed in a housing provided with a door on the front surface,
A fire hydrant device for supplying fire-extinguishing water to a nozzle, comprising a hose storage portion having an opening at the front surface and into which a hose is to be wound, and having a flexible portion which contacts the upper edge or upper and lower edges of the opening when the hose is pulled out. Because a contact member is provided,
When the hose is pulled out, the contact member comes into contact with the hose, which serves to reduce the momentum that is drawn out, thereby preventing the hose from becoming out of shape. Therefore, it is a matter of course that a plurality of abutting members may be provided on the upper edge portion or the upper and lower edge portions of the opening, and deceleration may be performed each time acceleration is performed.

According to a second aspect of the present invention, there is provided a fire hydrant device in which a hose having a nozzle is housed in a housing having a door on the front surface and fire water is supplied to the nozzle. Since the hose is provided with a hose storage portion and the opening is formed horizontally long, the hose does not collapse when the hose is pulled out, and the hose can be easily stored.
