  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the fire hydrant device 1 of the present embodiment, and FIG. 2 is a perspective view of the fire hydrant device 1 in a state where the hose holder 11 is pulled up to the upper end position. As shown in FIG. 1, the fire hydrant device 1 of the present embodiment has a box-shaped main body portion 10, and a fire hose 12 having a nozzle 13 at the tip, valves including a fire hydrant valve, and the like are included therein. It is stored. On the front surface of the main body 10 is provided a door 30 that can be opened during maintenance. The door part 30 has the handle part 30b which hooks a hand at the time of attachment or detachment in two places.

  In the event of a fire, as shown in FIG. 2, by pulling up the hose holder 11 housed in the main body 10, the fire hose 12 held by the hose holder 11 can be pulled out and fire extinguishing activities can be performed. . The fire hose 12 has a nozzle 13 at the tip.

  The hose holder 11 includes a box-shaped hose storage portion 20 that can store the wound fire hose 12, an upper surface portion 21 that constitutes the upper surface of the fire hydrant device 1, and a portion that is stored in the main body portion 10. It has the support | pillar part 22 provided in four corners. 3 is a front view of the fire hydrant apparatus 1 in a state where the hose holder 11 is pulled up to the upper end position, and FIG. 4 is a rear view of the fire hydrant apparatus 1 in a state where the hose holder 11 is pulled up to the upper end position. Each is shown. The hose accommodating part 20 has a front opening 20a for pulling out the fire hose 12 on the side part on the front side. Moreover, the hose accommodating part 20 has the back surface opening part 20b for drawing out the fire hose 12 in the side part of the back side. As shown in FIG. 4, the lower end edge 20c of the back surface opening 20b is disposed at a position lower than the lower end edge 20d of the front opening 20a.

  In FIG. 5, the explanatory view of the state which installed the fire hydrant apparatus 1 of this embodiment in the tunnel is shown. The tunnel has a supervisor passage 61 on the side of the road 60. The supervisor passage 61 is formed 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 supervisor passage 61. The fire hydrant apparatus 1 installed in the monitoring person passage 61 has the upper surface portion 21 substantially flush with the upper surface of the monitoring person passage 61. For this reason, it is possible to prevent the fire hydrant device 1 from obstructing the passage in the supervisor passage 61 during normal times.

  In the event of a fire, as shown in FIG. 2, the hose holder 11 protrudes upward, so that the front opening 20 a and the back opening 20 b of the hose storage part 20 are located above the upper surface of the supervisor passage 61. Are also exposed upwards. In this state, the fire hose 12 can be pulled out from the road 60 through the front opening 20a. Further, the fire hose 12 can be pulled out from the supervisor passage 61 through the rear opening 20b. Thus, 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, and thereby the front opening 20 a of the hose storage unit 20 that stores the fire hose 12. And the back opening 20b is exposed. For this reason, when the fire hydrant device 1 is installed so as to be embedded in the supervisor passage 61, the fire hose 12 can be pulled out from both the road 60 side and the supervisor passage 61 side. In particular, even if the automobile is stopped in front of the fire hydrant device 1, the fire hose 12 can be reliably pulled out because the hose holder 11 is structured to be pulled up with respect to the main body 10.

  In the fire hydrant apparatus 1 according to the present embodiment, the hose holder 11 has a front opening 20a on the road side and a back opening 20b on the monitoring staff passage side, and a 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 is easily dropped by its own weight, and the user can pull out the fire hose 12 with a small force. In addition, the fire hose 12 is not easily broken even during withdrawal, and the fire hose 12 having a desired length intended by the user can be easily pulled out. In addition, since the lower end edge 20c of the front opening 20a is at a high position, the wound fire extinguishing hose 12 stored is supported by the wall surface up to a higher position in the direction toward the road 60 side. Therefore, it is possible to make the fire hose 12 difficult to break.

  The front opening 20 a has a center position in the height direction at a substantially center position in the height direction of the hose holder 11 in a state of being pulled out above the main body 10. For this reason, the opening height of the front opening 20a can be sufficiently secured, and the fire hose 12 can be easily pulled out.

  The lower end edge 20 c of the front opening 20 a is located above the innermost lowermost end position 12 a of the fire hose 12 wound inside the hose holder 11. For this reason, about the front side of the fire hose 12 wound and accommodated in the hose holder 11, the lower part 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 hose 12 can be reliably prevented from falling to the front side.

  The nozzle 13 provided at the tip of the fire hose 12 has an upper end position 13 a disposed at the center within the hose holder 11. The lower end edge 20 c of the front opening 20 a is located below the upper end position 13 a of the nozzle 13. Thereby, since the nozzle 13 faces the front side directly, the nozzle 13 at the tip of the fire hose 12 can be easily taken out from the front opening 20a. The nozzle 13 is installed or engaged on the inner peripheral upper side or the inner peripheral lower side of the fire hose 12 wound inside the hose holder 11. For this reason, the position of the upper end position 13a of the nozzle 13 in the hose holder 11 may be closer to the upper side or lower side than the center portion.

  When the fire 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 supervisor passage 61. Since the supervisor passage 61 is formed at a position higher than the road 60, the force that the fire hose 12 falls into the supervisor passage 61 due to its own weight is weak. For this reason, even if the lower end edge 20d of the rear opening 20b is arranged at a high position, the effect of reducing the drawing force is small, but the fire hose 12 is necessary for getting over the lower end edge 20d of the rear opening 20b. The power increases, and the power required to pull out increases. In this embodiment, since the position of the lower end edge 20d of the rear opening 20b is lower than the position of the lower end edge 20c of the front opening 20a, when the fire hose 12 is pulled out from the supervisor passage 61 side, It is possible to reduce the resistance force applied to the fire hose 12 and suppress an increase in the drawing 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 rear opening 20b, the fire hose 12 can be pulled out from either the road 60 side or the supervisor passage 61. The pulling force can be reduced.

  The rear opening 20b has a central position in the height direction located below the central position in the height direction of the front opening 20a. 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 corresponds to the center position of the front opening 20a. It is on the lower side. Thereby, the area of the wall surface which supports the fire hose 12 accommodated in the inside of the hose holding body 11 from the back side is sufficiently secured, and the fire hose 12 can be taken out from the back side while facilitating the removal of the fire hose 12. Can be supported so as not to fall.

  The lower end edge 20d of the rear opening 20b is within the range of the width at the lowermost end of the portion 12b located on the innermost periphery of the fire hose 12 wound inside the hose holder 11 in the height direction. Is located. Thereby, since all the fire hose 12 located in the lower part is supported by the wall surface on the back side of the hose holder 11 on the back side of the fire hose 12, the fire extinguishing is performed when the hose holder 11 is pulled upward. The hose 12 can be reliably prevented 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 hose 12 can be pulled out from the hose holder 11. A confirmation line 11a exposed to the front side in the state of FIG. 3 is displayed on the front side surface of the hose holder 11. Further, as shown in FIG. 4, a confirmation line 11 b is also displayed on the rear surface of the hose holder 11. When the hose holder 11 is pulled up from the state in which the hose holder 11 is stored in the main body 10 and the fire hose 12 can be pulled out, the confirmation lines 11a and 11b of the hose holder 11 are connected to the main body. 10 is exposed to the outside, the user can easily confirm whether or not the hose holder 11 has been pulled up to a position where the fire hose 12 can be used.

In FIG. 6, the longitudinal cross-sectional view of the fire hydrant apparatus 1 cut | disconnected in front vicinity is shown. As shown in this figure, a hose holder 11 containing a fire hose 12 is housed in the main body 10, and the main body 10 has a drive unit 31 for raising and lowering the hose holder 11. ing.

  The drive unit 31 includes an elastic drive member 32 fixed to the main body unit 10, a wire 33 that connects the elastic drive member 32 and the hose holder 11, and two pulley members 34 and 35 on which the wire 33 is hooked. Has been. The elastic drive member 32 is a spring member that urges the wire 33 in the pulling direction in a state in which the hose holder 11 is housed in the main body 10, and a conston spring is used. The Conston spring generates a constant urging force within a predetermined stroke range. The elastic drive member 32 is not limited to a conston spring, and other types of elastic members may be used.

  The wire 33 extending upward from the elastic drive member 32 is changed in the horizontal direction by the pulley member 34 and further changed in the downward direction by the pulley member 35. The wire 33 is connected and fixed to a wire fixing portion 25 formed at the lower portion of the hose holder 11 at the lower end portion. Since the elastic drive member 32 is biased in the direction in which the wire 33 is pulled, the hose holding body 11 having the wire 33 fixed to the lower portion is biased in the direction in which it is pulled upward.

  As shown in FIG. 1, a lock release portion 24 is provided on the upper surface portion 21 of the hose holder 11. The lock release unit 24 is linked to a lock engagement unit 23 that is engaged with the main body unit 10. Since the lock engaging portion 23 is engaged with the main body portion 10, the state of being accommodated in the main body portion 10 is maintained against the urging force of the elastic drive member 32. When the lock release unit 24 is operated so as to be pushed up, the lock engagement unit 23 linked to the lock release unit 24 is released from the engagement state with the main body unit 10. When the engagement state of the lock engagement portion 23 with respect to the main body portion 10 is released, the hose holder 11 is pulled upward by the wire 33 by the urging force of the elastic drive member 32. The urging force of the elastic drive member 32 is set to be greater than the weight of the hose holder 11 that houses the fire hose 12. For this reason, the hose holding body 11 from which the engagement state of the lock engaging portion 23 is released is automatically pulled upward only by the urging force of the elastic drive member 32.

  In FIG. 7, the cross-sectional view of the fire hydrant apparatus 1 cut | disconnected by upper surface vicinity is shown.
