<Hose storage>
The hose storage portion 9 includes two columnar bodies 41 extending from the upper surface of the inner wall of the main body portion 5 to the lower surface of the inner wall, and two strips bent in a substantially L shape from the columnar body 41 to the back surface of the inner wall on the front surface of the main body portion 5. It is configured to include a plate 43 (see FIGS. 2 and 6).

As shown in FIGS. 2 and 3, the hose storage portion 9 stores the hose 7 wound inward in the vertical direction. The storage method of the hose 7 stored in the hose storage unit 9 is not limited to the inward winding type in which the hose 7 is stored by being wound inward, and may be, for example, a reel type in which the hose is wound and stored in a reel.
Further, as shown in FIG. 3, the hose storage portion 9 is provided near the back surface in the main body portion 5, and a space S is formed between the hose storage portion 9 and the front panel 30 and the front door 35 of the main body portion 5. (See Fig. 3). The hose 7 can be pulled out if the space S has a depth of about the maximum diameter (length including the grip portion) of the fire extinguishing nozzle 11. That is, the formation of the space S facilitates the pulling out of the hose 7 and secures the installation space for the nozzle holder 13.
The fire extinguishing nozzle 11 is provided at the tip of the hose 7 and radiates fire extinguishing water (including an aqueous foam solution).

<Nozzle holder>
As shown in FIG. 2, the nozzle holder 13 is provided at a position above the middle in the height direction in the vicinity of the hose accommodating portion 9. Specifically, when the fire extinguishing nozzle 11 is taken out by putting a hand through the upper surface opening 23, the position of the nozzle holder 13 is set at a position where the fire extinguishing nozzle 11 can be grasped by the time it reaches the elbow, which is more specific. Is located 30 to 40 cm below the top plate portion 3.
Further, as shown in FIG. 3, the nozzle holder 13 is closer to the front panel 30 than the front surface of the hose accommodating portion 9 in a plan view, and is provided below the upper surface opening portion 23. In other words, the nozzle holder 13 is arranged on the front side of the strip 43 in the plan view.
The reason why the nozzle holder 13 is installed in this way is that the fire extinguishing nozzle 11 can be taken out from both the front side and the upper surface side of the main body 5.

As shown in FIG. 5, which is a perspective view from the back side, the nozzle holder 13 has a mounting plate 45 attached to the strip 43 constituting the hose storage portion 9, and an L-shape fixed to the back surface of the mounting plate 45. It is provided with a support portion 47 made of the metal fittings of the above, and a nozzle holding piece 49 rotatably attached to the support portion 47.
Further, as shown in FIG. 5, the mounting plate 45 includes a mounting piece portion 45a for mounting on the strip plate 43, and a contact surface portion 45b to which the support portion 47 is mounted and which functions as a contact plate.
Two slit portions 51 through which the nozzle holding piece 49 can pass are formed in the contact surface portion 45b at predetermined intervals.

In the present embodiment, two C-shaped nozzle holding pieces 49 are attached to both ends of a U-shaped arm member 53 at predetermined intervals, and the arm pieces of the arm member 53 are attached.

The nozzle holding piece 49 is made of elastic resin, for example, and by pushing the fire extinguishing nozzle 11 through the C-shaped notch 57, the fire extinguishing nozzle 11 elastically deformed and passed through the notch 57 is inserted into the opening 59. Hold with.

The nozzle holding piece 49 rotates by its own weight in a free state in which the fire extinguishing nozzle 11 is not attached, and is located on the back surface side of the contact surface portion 45b as shown in FIG. 5A.
When the nozzle holding piece 49 is rotated to the front side from the state of FIG. 5 (a), as shown in FIG. 5 (b), the nozzle holding piece 49 passes through the slit portion 51 and the front surface of the contact surface portion 45b. Get out to the side. In the state shown in FIG. 5B, almost the entire nozzle holding piece 49 protrudes to the front side of the contact surface portion 45b, and the notch portion 57 faces the front side. In this state, as shown in FIGS. 6 and 7, the fire extinguishing nozzle 11 can be held and removed by pushing it into the nozzle holding piece 49 from the front side. When the fire extinguishing nozzle 11 is held, the fire extinguishing nozzle 11 comes into contact with the contact surface portion 45b to restrict the rotation of the nozzle holding piece 49, and the fire extinguishing nozzle 11 is held in the states of FIGS. 6 and 7.

When the nozzle holding piece 49 is further rotated, as shown in FIG. 5C, the notch portion 57 faces upward, and in this state, the fire extinguishing nozzle 11 can be removed from the upper side.
That is, when the fire extinguishing nozzle 11 is grasped and pulled upward, the nozzle holding piece 49 rotates and the notch portion 57 faces upward as shown in FIGS. 8 and 9. As a result, the fire extinguishing nozzle 11 can be removed by pulling up the fire extinguishing nozzle 11 as it is.

When the fire extinguishing nozzle 11 is removed, the nozzle holding piece 49 rotates due to its own weight and moves to the back side of the contact surface portion 45b as shown in FIGS. 10 and 11. Therefore, for example, when the hose 7 is pulled out from the front opening 33, the nozzle holding piece 49 does not interfere with the hose 7. This point is the same when the hose 7 is pulled out from the upper surface opening 23.

<Fire extinguishing nozzle fall prevention rod>
The fire extinguishing nozzle fall prevention rod 15 is one aspect of the fire extinguishing nozzle fall prevention means of the present invention, and is arranged below the hose 7 with the nozzle holding piece 49 holding the fire extinguishing nozzle 11 and the fire extinguishing nozzle 11 is a nozzle holder. It supports the hose 7 and prevents the hose 7 and the fire extinguishing nozzle 11 from falling when the hose 7 is separated from the 13.
The fire extinguishing nozzle fall prevention rod 15 is attached to the columnar body 41 on the side closer to the nozzle holding piece 49 among the columnar bodies 41 constituting the hose storage portion 9.

The fire extinguishing nozzle fall prevention rod 15 is composed of a rod-shaped body extending from the columnar body 41 toward the front panel 30 side. A slight gap is formed between the tip of the fire extinguishing nozzle fall prevention rod 15 and the inner surface of the front panel 30, but this gap is set smaller than the diameter of the hose 7. By doing so, it is possible to prevent the hose 7 from slipping through the gap between the fire extinguishing nozzle fall prevention rod 15 and the front panel 30 and falling.

Regarding the position of the fire extinguishing nozzle fall prevention rod 15 in the height direction, the appropriate position is when the hose 7 is extended to the side while the fire extinguishing nozzle 11 is held by the nozzle holding piece 49 as shown in FIG. It is the lower surface position of the hose 7. This makes it possible to prevent the hose 7 from interfering with the fire extinguishing nozzle 11 when it is held by the nozzle holding piece 49.
The position of the fire extinguishing nozzle fall prevention rod 15 in the height direction is not limited to that, and the upper limit of the position is a position below the back surface of the upper door 25 by the diameter of the hose 7.
Further, the lower limit of the position of the fire extinguishing nozzle fall prevention rod 15 needs to be set so that the hose 7 can be taken out from the upper surface opening 23 while the hose 7 is supported by the fire extinguishing nozzle fall prevention rod 15. Specifically, it is desirable that the height is higher than the position 60 cm below the top plate portion 3. More preferably, the position is such that the hose 7 supported by the worker's arm reaching the elbow can be reached, and more specifically, the position is 30 to 40 cm below the top plate portion 3.

<Operating lever>
The operating lever 17 is for operating the fire hydrant valve, and is provided on the columnar body 41 on the side of the hose accommodating portion 9 near the nozzle holder 13, as shown in FIG. The position where the operation lever 17 is provided may be a position where the operator can operate from both the front opening 33 and the upper surface opening 23, similarly to the position where the nozzle holder 13 is provided.
Specifically, the position of the operation lever 17 is the same as the position where the nozzle holder 13 is provided, and when the operation lever 17 is operated by inserting a hand from the upper surface opening 23, until the operator's arm reaches the elbow. The position of the operation lever 17 is set to a position where the operation lever 17 can be operated, and more specifically, the position is 30 to 40 cm below the top plate portion 3.
Further, as shown in FIG. 3, the operating lever 17 is closer to the front panel 30 than the front surface of the hose accommodating portion 9 in a plan view, and is provided below the upper surface opening portion 23. In other words, in a plan view, the operating lever 17 is arranged on the front side of the strip 43 from the front side.

Next, regarding the fire hydrant device 1 configured as described above, a method of removing the fire extinguishing nozzle 11 and a method of pulling out the hose 7 will be described in detail.
<When removing the fire extinguishing nozzle from the front opening>
When the front door 35 is opened, a state in which the fire extinguishing nozzle 11 is held by the nozzle holder 13 can be seen as shown in FIG. As described above, the position of the nozzle holder 13 is provided in front of the hose storage portion 9, and the fire extinguishing nozzle 11 can be easily reached. As described above, since the nozzle holding piece 49 is rotatable, it can be rotated even when the fire extinguishing nozzle 11 is held, but from the state where the fire extinguishing nozzle 11 is in contact with the contact surface portion 45b. It cannot rotate to the back side, that is, the fire extinguishing nozzle 11 comes into contact with the contact surface portion 45b to restrict movement, and is held in the state shown in FIGS. 6 and 7.
Further, in the state shown in FIGS. 6 and 7, the notch 57 (see FIG. 5) of the nozzle holding piece 49 faces the front side. Therefore, by pulling the fire extinguishing nozzle 11 toward the front side, the fire extinguishing nozzle 11 can be opened. Can be removed.
Since the fire extinguishing nozzle fall prevention rod 15 is a straight rod-shaped body, the hose 7 does not get caught when the fire extinguishing nozzle 11 is pulled toward the front side, and there is no problem in removing the fire extinguishing nozzle 11.

<When taking out the fire extinguishing nozzle from the top opening>
When the upper surface door 25 is opened and the fire extinguishing nozzle 11 is taken out, when the upper surface door 25 is opened, the fire extinguishing nozzle 11 can be seen from the upper surface opening 23 as shown in FIGS. 3 and 14. As described above, the position of the nozzle holder 13 is above the middle in the height direction of the main body 5, and the fire extinguishing nozzle 11 held can be reached by inserting the arm from the upper surface opening 23. ..
When an arm is inserted through the upper surface opening 23 to grab the fire extinguishing nozzle 11 and pull it upward, the nozzle holding piece 49 rotates and the notch 57 faces upward, and the fire extinguishing nozzle 11 remains as it is. The fire extinguishing nozzle 11 can be removed by pulling it upward (see FIGS. 8 and 9).

When the fire extinguishing nozzle 11 is removed, as described above, the nozzle holding piece 49 rotates by its own weight and moves to the back side of the contact surface portion 45b, and when the hose 7 is pulled out from the front opening 33, the nozzle holding piece 49 Does not interfere with the hose 7 (see FIGS. 10 and 11).
Since there is a space S between the hose storage portion 9 and the front panel 30, the hose 7 does not interfere with the internal equipment, the front panel 30, the front door 35, etc. when the hose 7 is pulled out, and the hose is pulled out smoothly. Is possible.
As for the distance in the depth direction of the space S, assuming that the fire extinguishing nozzle 11 is taken out by lifting it upward, the maximum width W of the fire extinguishing nozzle 11 (that is, the width of the handle portion of the fire extinguishing nozzle 11) (see FIG. 7). It is preferable to set the above.
Further, as described above, by providing the catch prevention member on the side portion of the upper surface opening portion 23 extending in the depth direction, the hose 7 can be smoothly pulled out without being caught on the side portion of the upper surface opening portion 23.

If you accidentally let go of the fire extinguishing nozzle 11 when taking out the fire extinguishing nozzle 11, the fire extinguishing nozzle 11 will fall. Since the 7 is supported, the supported hose 7 can be grasped and taken out from the upper surface opening 23.
If the fire extinguishing nozzle fall prevention rod 15 is not provided, the fire extinguishing nozzle 11 falls together with the hose 7 to the bottom surface of the main body 5, so that the fire extinguishing nozzle 11 cannot be taken out from the upper surface opening 23. In this case, the worker descends from the observer passage 83 to the road 85, opens the front door 35, and takes out the fire extinguishing nozzle 11. However, in an emergency situation of fire, such a mode is used for fire extinguishing activities. Where it is necessary to avoid the delay, this can be avoided by having the fire extinguishing nozzle fall prevention rod 15, and the effect of the fire extinguishing nozzle fall prevention rod 15 is great.

As described above, in the fire hydrant device 1 of the present embodiment, the top plate portion 3 becomes a part of the road surface of the observer passage 83 and can pass through, and the hose 7 is pulled out, the operation lever 17 is operated, and the operation lever 17 is operated. The fire extinguisher 31 can be taken out from both the front side and the upper surface side.

In particular, in the fire hydrant device 1 of the present embodiment, the nozzle holder 13 is provided at a position closer to the front panel 30 than the front surface of the hose storage portion 9 in a plan view and above the middle in the vertical direction. As a result, the fire extinguishing nozzle 11 can be easily reached from either the front opening 33 or the upper surface opening 23. Therefore, the fire extinguishing nozzle 11 is taken out from either the front opening 33 or the upper surface opening 23, and the hose 7 is removed. Can be pulled out.
