  In recent years, there has been a demand for easier maintenance such as transportation and installation work of fire hydrant devices and reduction of replacement costs, with the front panel and main body that make up the housing divided into structures. Then, it is conceivable that the front panel or the main body can be divided. In that case, the fire hydrant door needs to be within the range of the lateral width of the hose storage part, not the piping system storage part.

  However, when the horizontal width of the forward-extinguishing type fire hydrant door is reduced to the same extent as that of the hose housing, when the nozzle is arranged so as to be parallel to the width direction of the fire hydrant door in the open state as in the prior art, Since the bending radius of the fire extinguishing hose is reduced, an excessive load may be applied to the fire extinguishing hose, which may lead to breakage or breakage. In addition, when the hydrant valve opening / closing lever and lever protection bar are arranged in a vertical state as in the prior art, it is inconvenient for the opening and closing operation of the hydrant door due to contact with the hose from the nozzle to the hose storage part and the components of the hose storage part. If a space is provided in order to solve this problem, the housing becomes large.

  This invention prevents the inconvenience even if the nozzle and the hydrant valve opening / closing lever are arranged on the inner surface of the hydrant door when the width of the forward-extinguishing type hydrant door is reduced to the same extent as that of the hose housing. It is for the purpose.

The hydrant door is arranged on the inner surface side of the fire hydrant door so as to be in a non-parallel state with respect to the width direction and so that a tip portion faces the upper side of the hydrant door.

  Further, a fire hydrant valve opening / closing lever is horizontally disposed on a side portion on the inner surface side of the fire hydrant door.

  The fire hydrant valve opening / closing lever does not protrude from the inside of the fire hydrant door.

  Moreover, the said main body is formed so that division | segmentation is possible in the said piping system storage part, a hose storage part, and a fire extinguisher storage part.

  According to this invention, the piping system storage unit that stores the piping system connected to the water supply source, the hose storage unit that stores the fire hose that is connected to the piping system and includes the nozzle, and the fire extinguisher storage unit are internally provided. And a plurality of front surfaces formed in a frame shape having openings, respectively provided on the front side of the main body and divided by the piping system storage portion, the hose storage portion, and the fire extinguisher storage portion. A fire hydrant device in which a housing is configured by a panel, and a forward-extinguishing type fire hydrant door is provided in an opening of a front panel for a hose storage unit, wherein the nozzle is in an open state of the fire hydrant door, The width of the fire hydrant door is arranged on the inner surface side of the fire hydrant door so that the distal end portion faces the upper side of the fire hydrant door. Comparable to that of If it is reduced, even by arranging the nozzle to the inner surface of the fire hydrant door, and can be the installation direction of the nozzle and the angle that does not put an excessive load on the fire fighting hose, broken or damage does not occur. In addition, the angle at which the operator can easily grasp the nozzle during a fire makes it easy to perform fire extinguishing work.

  In addition, since the fire hydrant valve opening / closing lever is disposed horizontally on the inner side of the fire hydrant door, the hose and the hose storage part from the nozzle to the hose storage part with the fire hydrant door closed are shown. The casing can be reduced in thickness without coming into contact with the components. In addition, when the fire hose is pulled out in the event of a fire, the fire hose is pulled out while scrubbing over the inside of the fire hydrant door and the fire hydrant valve opening / closing lever. The lever protection bar can be dispensed with because the fire hose can no longer be pulled out due to erroneous operation or contact with the open / close lever. At this time, it is more preferable that the hydrant valve opening / closing lever does not protrude from the inside of the hydrant door.

  Then, by arranging the nozzle and the fire hydrant valve opening / closing lever in combination as described above, even if the nozzle and the fire hydrant valve opening / closing lever are arranged on the inner surface of the fire hydrant door having a limited width, it is possible to prevent inconvenience.

  Further, since the main body is formed so as to be separable by the piping system storage part, the hose storage part, and the fire extinguisher storage part, the entire housing can be divided, and the fire hydrant apparatus can be transported and installed. It is possible to facilitate the maintenance and the maintenance such as the replacement cost reduction.
