Each is shown. The hose storage portion 20 has a front opening 20a for pulling out the fire extinguishing hose 12 on the side portion on the front side. Further, the hose storage portion 20 also has a back opening 20b for pulling out the fire extinguishing hose 12 on the side portion on the back side. As shown in FIG. 4, the lower end edge 20c of the back opening 20b is arranged at a position lower than the lower end edge 20d of the front opening 20a.

FIG. 5 shows an explanatory view of a state in which the fire hydrant device 1 of the present embodiment is installed in a tunnel. The tunnel has an observer passage 61 on the side of the road 60. The observer passage 61 is formed so as to have a height of about 1 m along the length direction of the road 60. The fire hydrant device 1 is installed so as to be embedded in the observer passage 61. In the fire hydrant device 1 installed in the observer passage 61, the upper surface portion 21 is substantially flush with the upper surface of the observer passage 61. Therefore, in the normal state, the fire hydrant device 1 can be prevented from hindering the passage in the observer passage 61.

In the event of a fire, as shown in FIG. 2, the hose holder 11 projects upward so that the front opening 20a and the back opening 20b of the hose storage portion 20 are projected from the upper surface of the observer passage 61.

Further, the fire extinguishing hose 12 can be pulled out from the observer passage 61 through the back opening 20b. As described above, the fire hydrant device 1 of the present embodiment has a structure in which the hose holder 11 is pulled upward from the main body 10, whereby the front opening 20a of the hose storage portion 20 for accommodating the fire extinguishing hose 12 And the back opening 20b are exposed. Therefore, when the fire hydrant device 1 is installed so as to be embedded in the observer passage 61, the fire extinguishing hose 12 can be pulled out from both the road 60 side and the observer passage 61 side. In particular, even if the automobile is stopped in front of the fire hydrant device 1, the hose holder 11 is pulled up with respect to the main body 10, so that the fire hose 12 can be reliably pulled out.

In the fire hydrant device 1 of the present embodiment, the hose holder 11 has a front opening 20a on the road side and a back opening 20b on the observer passage side, and the lower end edge 20c of the front opening 20a is a back opening. It is arranged above the lower end edge 20d of 20b. When the fire hose 12 is pulled out from the front opening 20a, the fire hose 12 falls from the lower end edge 20c of the front opening 20a to the road 60 at a lower position. Since the position of the lower end edge 20c of the front opening 20a is high, the fire hose 12 can easily fall due to its own weight, and the user can pull out the fire hose 12 with a small force. Further, the fire extinguishing hose 12 does not easily come apart even during the drawing, and the fire extinguishing hose 12 having a desired length intended by the user can be easily pulled out. Further, since the lower end edge 20c of the front opening 20a is at a high position, the wound and stored fire extinguishing hose 12 is supported by the wall surface to a higher position with respect to the direction toward the road 60 side. Therefore, the fire hose 12 can be made difficult to come apart.

The center position of the front opening 20a in the height direction is substantially the center position in the height direction of the hose holder 11 in a state of being pulled out above the main body 10. Therefore, a sufficient opening height of the front opening 20a can be secured, and the fire hose 12 can be easily pulled out.

The lower end edge 20c of the front opening 20a is located above the innermost lower end position 12a of the fire extinguishing hose 12 wound inside the hose holder 11. Therefore, the lower portion of the front side of the fire extinguishing hose 12 wound and stored in the hose holder 11 is supported by the wall surface of the hose holder 11 over the entire height. Therefore, when the hose holder 11 is pulled upward, the fire extinguishing hose 12 can be reliably prevented from falling to the front side.

The nozzle 13 provided at the tip of the fire extinguishing hose 12 has an upper end position 13a arranged at the center inside the hose holder 11. The lower end edge 20c of the front opening 20a is located below the upper end position 13a of the nozzle 13. As a result, since the nozzle 13 faces the front side directly, the nozzle 13 at the tip of the fire extinguishing hose 12 can be easily taken out from the front opening 20a. The nozzle 13 is installed or engaged with the upper inner circumference or the lower inner circumference of the fire extinguishing hose 12 wound inside the hose holder 11. Therefore, the position of the upper end position 13a of the nozzle 13 inside the hose holder 11 may be closer to the upper side or the lower side than the central portion.

When the fire extinguishing hose 12 is pulled out from the back opening 20b, the fire hose 12 falls from the lower end edge 20d of the back opening 20b to the observer passage 61. Since the observer passage 61 is formed at a position higher than the road 60, the force with which the fire extinguishing hose 12 falls into the observer passage 61 due to its own weight is weak. Therefore, even if the lower end edge 20d of the back opening 20b is arranged at a high position, the effect of reducing the pulling force is small, but the fire hose 12 is required to get over the lower end edge 20d of the back opening 20b. The force increases, and the force required for withdrawal increases. In the present embodiment, the position of the lower end edge 20d of the back opening 20b is lower than the position of the lower end edge 20c of the front opening 20a, so that when the fire extinguishing hose 12 is pulled out from the observer passage 61 side. It is possible to reduce the resistance applied to the fire extinguishing hose 12 and suppress the increase in the pulling force. That is, by appropriately setting the position of the lower end edge 20c of the front opening 20a and the position of the lower end edge 20d of the back opening 20b, the fire hose 12 can be pulled out from either the road 60 side or the observer passage 61. , The pulling force can be reduced.

The center position of the back opening 20b in the height direction is located below the center position of the front opening 20a in the height direction. Since the lower end edge 20d of the back opening 20b is located below the lower end edge 20c of the front opening 20a as described above, the center position of the back opening 20b also corresponds to the center position of the front opening 20a. It is lower. As a result, a sufficient area of the wall surface for supporting the fire extinguishing hose 12 housed inside the hose holder 11 from the back side is secured, and the fire extinguishing hose 12 is on the back side while facilitating the removal of the fire extinguishing hose 12. Can be supported so that it does not fall into the hose.

The lower end edge 20d of the back opening 20b is within the width range at the lowermost end of the innermost portion 12b of the fire extinguishing hose 12 wound inside the hose holder 11 in the height direction. Is located in. As a result, with respect to the back side of the fire extinguishing hose 12, all the fire extinguishing hoses 12 located at the lower part are supported by the wall surface on the back side of the hose holder 11, so that when the hose holder 11 is pulled upward, the fire is extinguished. It is possible to reliably prevent the hose 12 from falling to the back side.

FIG. 3 shows a state in which the hose holder 11 is pulled up to a position where the fire extinguishing hose 12 can be pulled out from the hose holder 11. A confirmation line 11a exposed on the front side in the state of FIG. 3 is displayed on the front surface of the hose holder 11. Further, as shown in FIG. 4, a confirmation line 11b is also displayed on the back surface of the hose holder 11. When the hose holder 11 is pulled up from the state of being stored in the main body 10 and the hose holder 11 is pulled up to a position where the fire extinguishing hose 12 can be pulled out, the confirmation lines 11a and 11b of the hose holder 11 are the main body. Since it is exposed to the outside of 10, the user can easily confirm whether or not the hose holder 11 has been pulled up to a position where the fire extinguishing hose 12 can be used.
