[First Embodiment of Nozzle Locking Structure]
(Nozzle locking structure)
FIG. 4 is an explanatory view showing the fire hydrant storage box provided with the first embodiment of the nozzle locking structure from the front, and FIG. 5 is an explanatory view showing the nozzle locking structure of FIG. 4 with the front side of the housing broken. FIG. 6 is an explanatory view showing a fire hydrant storage box having the first embodiment of the nozzle locking structure from a plane.

As shown in FIGS. 4 to 6, the nozzle locking structure 86 of the present embodiment includes a nozzle holder 88 and a hose using a ring-shaped holder metal fitting that opens downward in the lateral direction of the back surface of the second upper door 36. The holder 90 is arranged.

As shown in the plane of FIG. 6, the nozzle holder 88 and the hose holder 90 are arranged along the axis line 91 parallel to the axis core line in which the second upper door 36 is opened and closed by the hinge 44, and the second upper door 36 is arranged along the axis core line 91. The axis 91 is the lateral center line of the second upper door 36.

A foam nozzle 78 is connected to the tip of the hose 76 housed in the housing 31 via a swivel joint 94 that functions as a rotatable joint, and a cylindrical nozzle body provided with a grip 93 in the foam nozzle 78. The 92 is detachably locked by being fitted into the nozzle holder 88 on the back surface of the second upper door 36, and the tip end side of the hose 76 is attached to the hose holder 90 following the nozzle holder 88 on the back surface of the second upper door 36. It is detachably locked by being fitted.

Further, since the nozzle holder 88 and the hose holder 90 are arranged along the axis line 91 which is the center line in the lateral direction of the second upper door 36, the bubble nozzle 78 is arranged together with the tip side of the hose 76 in the second position. It is locked coaxially with the lateral center line of the upper door 36.

Further, the hose 76 connected to the foam nozzle 78 locked by the nozzle holder 88 bends downward due to the weight of the hose after being locked to the hose holder 90, and descends to the hose storage portion. By locking the tip of the hose 76 with a hose 76 , kink (bending) at the nozzle connecting portion due to the weight of the hose 76 is prevented.

(Internal structure of fire hydrant storage box)
7A and 7B are explanatory views showing the internal structure of the fire hydrant storage box, FIG. 7A shows the front surface, and FIG. 7B shows a plane seen from the XX cross section of FIG. 7A.

As shown in FIG. 7, the inner lower side of the housing 31 in the fire hydrant storage box 30 is a hose storage portion 74, and the hose 76 having a shape-retaining structure is horizontally stacked and wound inward.

The rectangle seen from the plane of the housing 31 has a width of about 1.4 meters and a depth of about 0.35 meters. Therefore, when the hose 76 is internally wound around the hose storage portion 74, the hose 76 is internally wound. The shape is a rounded rectangle consisting of two parallel lines and two semicircles, and the length of one turn of the hose 76 wound inward in the flat rectangular housing 31 is about 3.5 meters, and the hose length is about 3.5 meters. Since the hose requires 30 meters or more, the hose 76 may be wound inward by stacking 9 turns or more.

Here, the hose 76 wound inward in a rectangular shape with rounded corners in the housing 31 is indicated by parallel hose portions 76a and 76c and semicircular hose portions 76b and 76d.

A hose guide structure 80 is provided on the central front surface side of the housing 31 to inwardly deform the parallel hose portion 76a on the front surface side of the hose 76 that is internally wound in a rectangular shape with rounded corners.

In the hose guide structure 80, four guide pipes 80a, 80b, 80c, 80d using metal pipes are erected on the bottom plate 81, and the guide pipes 80a, 80d at both ends are erected along the inner surface of the housing 31. The central guide pipes 80b and 80c are erected apart from each other by a predetermined length, and the hose 76 is wound inward along the guide pipes 80a, 80b, 80c and 80d of the hose guide structure 80 so that the hose 76 is on the front side of the hose 76. The parallel wire hose portion 76a is deformed inward to form a shape close to a gourd shape, and due to this deformation, a repulsive force that tries to spread outward is generated in the deformed parallel wire hose portion 76a of the hose 76.

By providing such a hose guide structure 80, in the hose 76 that is vertically wound in the housing 31, the parallel wire hose portion 76a having rounded corners is deformed inward by the hose guide structure 80. As a result, a repulsive force that tries to spread outward is generated, and a force that presses against the inner wall side of the housing 31 is generated, so that even if the parallel wire hose portions 76a and 76c of the hose 76 that are repeatedly wound inward become long. It is possible to surely prevent it from collapsing inward.

Here, in the hose guide structure 80, the parallel wire hose portion 76a on the front side of the hose 76 is deformed inward, and the parallel wire hose portion 76c on the back side is not deformed inward, but is inward of the parallel wire hose portion 76a. Due to the deformation, the force of the hose 76 as a whole to spread outward increases, and it is possible to reliably prevent the parallel wire hose portion 76c on the back surface side, which has not been deformed inward, from collapsing inward.

Further, when the front door 32 and the second upper door 36 or the first upper door 34 are opened and the hose 76 is pulled out to the outside, the hose is pushed out due to the deformation of the semicircular hose portions 76b and 76d of the hose 76. In addition to the force, the parallel wire hose portion 76a of the hose 76 is also deformed inward by the hose guide structure 80 to generate a force to push out the hose 76, so that the pulling force of the hose 76 can be reduced.

In the upper part of the hose guide structure 80, guide pipes 82a to 82d and guide pipes 84a, 84b are formed so as to surround the inside of the front door opening 33, the first upper surface door opening 35, and the second upper surface door opening 37 shown in FIG.
