1A and 1B are schematic views of a fire engine according to the present embodiment, FIG. 1A is a top view, and FIG. 1B is a left side view. In some cases, the inside of the luggage compartment is also shown.
The fire engine is provided between the driver's cab 10 provided at the front of the vehicle and having a driving operation device and the like, the luggage compartment 20 provided at the rear of the vehicle for storing materials and equipment, and water provided between the driver's cab 10 and the luggage compartment 20. A water tank 30, a tire 40, and a chassis frame 50 are provided. The cab 10, the luggage compartment 20, and the water tank 30 are supported by a chassis frame 50 arranged below.
A pump 60 is installed at the front of the luggage compartment 20. The pump 60 is used for sucking water from a river, a pond, or the like, and is connected to a flexible hose 70 via a water supply pipe 90. The hose 70 is a suction tube whose tip 70a is thrown into a river, a pond, or the like and sucks up water. One end 90a of the water supply pipe 90 is connected to the rear end 70b of the hose 70, and the other end 90b of the water supply pipe 90 is connected to the pump 60. The water sucked up by the hose 70 is sent to the pump 60 through the water supply pipe 90 and used as a fire extinguishing agent.
The dimensions of the hose 70 are, for example, about 10 m in length and about 70 mm in inner diameter. Although the hose 70 can be bent and stored, the curvature cannot be made so large because it has a predetermined rigidity.

The luggage compartment 20 has a front panel 21, a rear panel 22, a left panel 23, a right panel 24, an upper panel 25, and a lower panel 26, and is formed in a box shape.
Between the upper panel 25 located at the upper end of the luggage compartment 20 and the lower panel 26 located at the lower end, a hose storage portion 80 having a hose mounting surface 81 is provided as a space for storing the hose 70 in a sideways state. It is provided.
Here, FIG. 2 is an image diagram of a fire engine having a hose storage portion. The arrow in FIG. 2 indicates the deployment direction of the hose 70. The height position of the hose mounting surface 81 is preferably 1/2 or more and 2/3 or less of the luggage compartment 20. By forming the hose storage portion 80 in the middle portion of the luggage compartment 20, the degree of freedom in layout can be increased as compared with the conventional case. For example, materials and equipment other than the hose 70 are loaded above and below the hose storage portion 80. Space can be provided. Note that FIG. 2 shows a state in which the hose car 160 is loaded below the hose storage portion 80.

Returning to FIG. 1, the hose storage unit 80 has a hose mounting plate 81A whose upper surface is a hose mounting surface 81 on which the hose 70 is mounted, and a plurality of hoses 70 for moving the hose 70 in and out of the hose mounting surface 81. Has an entrance / exit 82. The hose mounting surface 81 is rectangular and is arranged horizontally.
The hose mounting plate 81A was erected on a plate-shaped front wall 83 erected along the front end, a columnar left rear pillar 84 erected on the left rear end, and a right rear end of the hose mounting plate 81A. It has a columnar right rear column 85.
The plurality of entrances and exits 82 are a left doorway 82A provided between the front wall 83 and the left rear pillar 84 on the left side of the luggage compartment 20, and a front wall 83 and a right rear pillar 85 on the right side of the luggage compartment 20. The right doorway 82B provided between them and the rear doorway 82C provided between the left rear pillar 84 and the right rear pillar 85 on the rear side of the luggage compartment 20. The doorways 82 communicate with each other. By providing the entrances and exits 82 on both sides and the rear side of the luggage compartment 20 in this way, the hose 70 can be taken in and out from the side or the rear depending on the situation at the site and the like. Further, since the doorways 82 communicate with each other, the doorway 82 used for storage and the doorway 82 used for deployment do not necessarily have to be the same. Therefore, for example, the hose 70 stored from the left doorway 82A can be pulled out from the rear doorway 82C and deployed.
The dimensions of each entrance / exit 82 are, for example, a width of 1500 mm and a height of 210 mm when the hose 70 has a length of 10 m and an inner diameter of 70 mm. In this embodiment, the dimensions of each doorway 82 are the same, but the dimensions of each doorway 82 may be different, such as changing the width value between the left doorway 82A, the right doorway 82B, and the rear doorway 82C.

FIG. 3 is a diagram showing a hose storage portion in a state where the hose is stored, and FIG. 3 (a) shows a state in which the opening / closing bodies of all the entrances and exits are in the first state when the hose is stored, and FIG. 3 (b) is shown. ) Shows that the opening / closing body is in the second state only at the left entrance / exit. Further, FIG. 4 is a diagram showing a state in which the hose is unfolded from each entrance / exit.
One end 90a of the water supply pipe 90 is arranged at the center of the left and right of the front end of the hose storage portion 80. Further, an opening 83A is formed in the front wall 83, and one end 90a of the water supply pipe 90 is connected to the rear end 70b of the hose 70 through the opening 83A. As shown in FIG. 4, since one end 90a of the water supply pipe 90 is configured to be horizontally rotatable by a swivel or the like, the hose 70 can be smoothly stored and deployed from any entrance / exit 82.

Each doorway 82 is provided with an opening / closing body 100 capable of closing at least a part of the doorway 82. The opening / closing body 100 in this example has a plate shape.
The lower end of the opening / closing body 100 is fixed to the hose mounting plate 81A via a plurality of hinges 110, while the upper end is free and can be rotated up and down with the lower end as a rotation axis. The rotation range is, for example, horizontal +90 degrees upward and horizontal -80 degrees downward. As a result, the opening / closing body 100 can be changed between a first state in which at least a part of the doorway 82 is closed and a second state in which the doorway 82 is not closed. When the opening / closing body 100 is in the first state, the opening / closing body 100 becomes an obstacle and the hose 70 cannot be taken in and out of the hose mounting surface 81.

Further, on the front wall 83, the left rear pillar 84, and the right rear pillar 85, an inner stopper (not shown) that regulates the inward rotation of the opening / closing body 100 and an outward rotation of the opening / closing body 100 are restricted. A plurality of outer stoppers 120 are provided. The outer stopper 120 is provided at a position at a substantially intermediate height on each of the front wall 83, the left rear pillar 84, and the right rear pillar 85, and a part thereof can be projected toward the opening / closing body 100 side. It has become.
When changing the opening / closing body 100 from the second state to the first state, after rotating the opening / closing body 100 upward until it stands substantially perpendicular to the hose mounting surface 81, a part of the outer stopper 120 is removed. The downward rotation is restricted by projecting it so that it can come into contact with the front surface of the opening / closing body 100. As a result, the first state in which the opening / closing body 100 is erected substantially vertically is maintained. On the other hand, when the opening / closing body 100 is changed from the first state to the second state, the downward rotation restriction is released by retracting a part of the protruding outer stopper 120. As a result, the opening / closing body 100 rotates downward under its own weight and hangs down diagonally, and is in the second state.

When storing the hose 70, the hose 70 is placed on the hose mounting surface 81 while being curved in an annular shape from the rear end 70b side so that the hose 70 is stored in a local shape. At this time, the hose 70 is used for storage. If the entrance / exit 82 other than the entrance / exit 82 is open, the hose 70 mounted on the hose mounting surface 81 may protrude from the other entrance / exit 82 and cannot be stored properly.
Therefore, when the hose 70 is stored, the opening / closing body 100 is set to the first state only for one doorway 82 used for storage, and the other two doorways 82 are set to the second state. As a result, the hose 70 mounted on the hose mounting surface 81 can smoothly proceed with the storage work without slipping off from the other entrance / exit 82.
Further, it is preferable that the opening / closing body 100 is arranged from one end to the other end of the entrance / exit 82 as in the present embodiment. As a result, the gap (opening) of the entrance / exit 82 when the opening / closing body 100 is in the first state becomes smaller, so that the hose 70 can be more reliably prevented from slipping off. Further, by forming the opening / closing body 100 into a plate shape, the gap between the entrance / exit 82 can be made smaller than in the case of a rod shape.

Next, another example of the opening / closing body 100 will be described.

It shows that the opening / closing body of the doorway is in the second state. Further, FIG. 10 is a diagram showing a stored state and an expanded state of the hose, and FIG. 10 (a) shows a state in which the open / close bodies of all the entrances and exits are in the first state when the hose is stored, and FIG. 10 (b) is shown. Shows how the hose is deployed with the open / close body in the second state only at the left entrance / exit.
The opening / closing body 100 in this example has a rod shape. Further, at the four corners of the hose mounting plate 81A, end holders 130 having grooves formed in the vertical direction are provided. The position of the lower end of the groove is near the hose mounting surface 81, and the position of the upper end of the groove is approximately the intermediate height of the entrance / exit 82.
Both ends of the rod-shaped opening / closing body 100 are movably fitted in the groove of the end holder 130, and the first state is achieved by moving the rod-shaped opening / closing body 100 to the upper end along the groove, and the first state is achieved by moving the rod-shaped opening / closing body 100 to the lower end along the groove. It can be in two states. By forming the opening / closing body 100 into a rod shape, friction with the hose 70 can be reduced as compared with the case of a plate shape, and the stored state of the hose 70 can be easily visually recognized.
