Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a fire hydrant apparatus including a hose accommodating portion that accommodates a hose for fire extinguishing inward in a housing.

A hose accommodating portion for accommodating a hose for fire extinguishing (hereinafter simply referred to as "hose") is provided in a housing of the fire hydrant device, and the hose accommodated in the hose accommodating portion is a strong hollow circular cross-section. A shape-retaining hose having a shape-retaining property, which is internally wound and accommodated in a hose accommodating portion.
A front door is provided on the front panel of the fire hydrant device, and a fire extinguishing nozzle is held or an operation lever is provided on the inner surface side when the front door is closed.

  The above-mentioned inner winding is a winding method in which the hose 63 is wound from the inside against the frame as shown in FIG. It is wound in the order of the numbers. That is, as shown in FIG. 8, the hose 63 is wound from the rear to the outermost periphery in order from the rear toward the front (circled numbers 1 to 6). Enter and roll from the front to the back (7 to 12 of the circled numbers). Furthermore, when it reaches the rearmost side, it enters inside and winds from the rear side toward the front (the circled numbers 13 to 18).

  When pulling out the internally wound hose as described above, a phenomenon may occur in which the hose is drawn out alone (or in a chain) from the hose storage portion, a so-called blow-off phenomenon of the hose. When this loosening phenomenon occurs, the hoses charged one after another are piled up on the previously pulled out hose, and the subsequent pulling out operation of the hose becomes difficult, which hinders the fire fighting activity.

  Therefore, in order to prevent the looseness phenomenon, Patent Document 1 discloses an "internal wrap type fire hydrant device having a hose storage portion having a hose opening portion for storing the shape retaining hose in the inside and delivering the shape retaining hose. In the above-mentioned internal loop type fire hydrant device, there is provided a hook member having a fixed end fixed to the fire hydrant device and an open end facing the hose opening in the lateral direction.
