The red indicator lamp 26 is always turned on so that the installation location of the fire hydrant apparatus 10 can be seen from a distance. In the event of a fire, when the transmitter 28 is pressed and the switch button is turned on, a transmission signal is transmitted to the fire receiver in the monitoring room, a fire alarm is issued, and a response signal is sent from the fire receiver accordingly, and the response lamp 30 To light up.

  A fire extinguisher door 32 is provided in the door opening 17, and the inside of the housing 12 corresponding to the fire extinguisher door 32 is used as a fire extinguisher storage portion, for example, containing two fire extinguishers. The fire extinguisher door 32 is provided with a handle 34. When the handle 34 is pulled forward, the latch is released, and the fire extinguisher door 32 can be opened forward with the left side as a hinge.

  FIG. 2 is a front view showing the internal structure of the first embodiment of FIG. 1 with the fire hydrant door and the maintenance door removed. In FIG. 2, a hose storage portion 36 is formed at the center of the housing 12, and a valve storage portion 38 is formed on the right side thereof.

  A frame pipe 40 formed in a U-shape is arranged in the hose storage portion 36 on the opening side. Hose buckets 42 are attached to both sides of the frame pipe 40 to form a hose storage space inside.

  A hose 44 is housed inside the hose storage portion 36 surrounded by the hose bucket 42 and the inner wall of the housing. Here, a hose connection port 46 is disposed in the right valve storage unit 38, and after connecting the primary side of the hose 44 to the hose connection port 46, the hose 44 is wound into the hose storage unit 36. However, in this case, the hose 44 is wound so that the hose 44 is clockwise when viewed from the door opening 16.

  That is, the hose 44 connected to the hose connection port 46 is first wound under the hose storage portion 36, and then is wound clockwise in the storage portion, and finally the hose tip to which the nozzle 48 is attached is connected to the frame pipe 40. A nozzle 48 is attached to and held by a nozzle holder 50 attached to the right hose bucket 42 from the upper opening of the hose guide 43 attached near the center.

  The nozzle 48 is arranged at the same height level next to the fire hydrant valve opening / closing lever 60 to facilitate the operation at the time of water discharge by taking out the nozzle 48 and operating the fire hydrant valve opening / closing lever 60. The hose guide 43 prevents the hose 44 from being broken by the frame pipe 40 in the vicinity of the hose connection port 46 when the hose 44 is all pulled out to the right.

  By storing the hose 44 in the right-handed inner winding with respect to the hose storage portion 36, the winding start portion 44 a of the hose 44 is sent to the lower portion of the hose storage portion 36 from the hose connection port 46 at the shortest distance. For this reason, as shown in FIG. 13, the hose 112 is left-handed and the hose wrapping start portion 112a is sent to the upper part of the hose storage portion. Can be shortened, and the volume of the hose storage portion 36 is reduced. As a result, the casing 12 can be thinned.

  Further, the hose entrainment start portion 44a is fed to the lower side of the hose storage portion 36 by right-hand winding, so that the hose 44 does not slide against the hose bucket 42, and the hose is wound by the conventional hose left-hand winding of FIG. There is no need for protection against sliding against the bucket, and the structure can be simplified.

  Further, the nozzle 48 at the tip of the hose taken out after being stored in the hose storage part 36 as a right-hand winding is detachably attached to the nozzle holder 50 with the water discharge part facing downward, and since the water discharge part faces downward, the fire hydrant door is attached. The nozzle 48 can be opened and removed with the water discharge part facing down, and the water will not be discharged unless the fire hydrant valve opening / closing lever 60 provided on the fire hydrant valve 54 is operated, but this is inexperienced for those operating in the event of a fire. Therefore, the nozzle 48 can be removed with a sense of security because the water outlet is not suitable for the user, and there is a great safety advantage.

  A valve storage part 38 disposed on the right side of the hose storage part 36 provided in the housing 12 has a fire hydrant valve 54 connected to a piping system from the fire hydrant connection port 52 to which the piping from the pump facility is connected to the hose connection port 46.
