Description

[Technical field]

[0001] The present invention relates to a firefighting vehicle. [Background technology]

[0002] In addition to large vehicles, there are also standard vehicles, compact vehicles, and light vehicles (hereinafter referred to as "compact fire engines"). Patent Document 1 describes a station wagon-type fire engine. Patent Document 2 describes a fire engine with an open-deck cargo bed. The cargo bed of the fire engine is loaded with various firefighting tools, such as various hoses (suction hoses, fire hoses, etc.), pumps, generators, and ladders. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2003-180856 A [Patent Document 2] Japanese Patent Application Publication No. 8-754 Summary of the Invention [Problem to be solved by the invention]

[0004] When a fire engine arrives at a fire scene, it is common to first set up the suction hose, followed by the pump and other hoses. Therefore, it is desirable for the suction hose to be installed in a position that makes it easy to access first.

[0005] In Patent Document 1, when facing the rear opening of the vehicle, the suction hose is arranged on the side of the luggage compartment, side by side with the pump. In this case, the worker removes the suction hose by pulling it out of the luggage compartment. However, the task of pulling out the suction hose is not easy and takes time.

[0006] In Patent Document 2, the suction hose is located behind other firefighting equipment, and the suction hose cannot be removed from the rear of the vehicle until the other firefighting equipment has been removed. However, in Patent Document 2, the loading platform has an open deck structure, so workers can remove the suction hose from the side of the vehicle. Even in this case, it is necessary to pull out the suction hose, and as with Patent Document 1, the work takes time.

[0007] The above describes the case where the suction hose is taken out first, but if other fire-fighting equipment needs to be taken out first and that other fire-fighting equipment is located to the side or at the back of the cargo bed, the work will take time, just as described above.

[0008] To provide a fire truck which allows firefighting equipment that needs to be installed first to be removed from the loading platform of the fire truck in a short time and also allows other firefighting equipment to be easily removed. [Means for solving the problem]

[0009] One aspect of the present invention is a loading platform having an opening on a rear surface or a side surface of a vehicle and a vertical wall portion adjacent to the opening; An outer door configured to open and close the opening; A support pillar is disposed on the loading platform and is disposed on one side edge of the opening; An inner door is disposed closer to the center of the platform than the outer door, configured to be rotatable on the support, and configured to allow installation of fire-fighting equipment; The inner door is An inner door body configured to be able to install the fire fighting equipment; The fire vehicle is provided with a connection portion having one end rotatably supported on the support pillar and the other end holding the inner door body, the surface facing the end of the vertical wall portion being formed concavely when the inner door is in an open state. Effect of the Invention

[0010] According to the above aspect, the fire engine includes an inner door. By installing the fire equipment that needs to be installed first in the inner door, the worker can easily take out the target fire equipment. However, due to the existence of the inner door, in order to take out the fire equipment behind the inner door, the inner door needs to be opened.

[0011] According to the above aspect, the inner door is configured to include an inner door main body and a connecting portion. One end of the connecting portion is rotatably supported by the support pillar, the other end holds the inner door main body, and a surface facing the end of the vertical wall portion of the loading platform when the inner door is in an open state is formed in a concave shape. Therefore, when the inner door is in an open state, it is possible to increase the rotation angle of the inner door main body while avoiding interference between the connecting portion and the vertical wall portion of the loading platform.

[0012] If the rotation angle of the inner door body is small, the width of the opening of the loading platform may be narrowed by the inner door body. However, as described above, the concave connection portion allows the rotation angle of the inner door body to be large. Therefore, the inner door body can be opened widely, and the opening width when the inner door is open can be secured large. As a result, other firefighting equipment placed behind the inner door can be easily taken out.

[0013] As described above, according to the above aspect, a fire truck can be provided which allows the fire fighting equipment that needs to be installed first to be removed from the loading platform of the fire truck in a short time, and also allows other fire fighting equipment to be easily removed.

[0014] It should be noted that the reference characters in parentheses in the claims indicate the corresponding relationship with the specific means described in the embodiments described later, and are not intended to limit the technical scope of the present invention.

[0016] The fire engine includes a bed of the vehicle, an outer door configured to open and close an opening of the bed, a support pillar disposed on the bed, and an inner door configured to be rotatable on the support pillar. The inner door includes an inner door body and a connecting portion having a concave surface that faces an end of the standing wall portion when the inner door is in an open state.

[0017] The connecting portion has a surface facing the end of the vertical wall portion when the inner door is in an open state formed in a curved concave shape. By making the connecting portion curved and concave, when the inner door is in an open state, it is possible to increase the rotation angle of the inner door body while avoiding interference between the connecting portion and the vertical wall portion of the loading platform. Furthermore, by making the connecting portion curved and concave, it is possible to increase the safety for workers when the inner door is in an open state.

[0018] In particular, the connection part is preferably formed in a curved U-shape when viewed from the axial direction of the support pillar, and the concave surface of the curved U-shape forms the surface facing the end of the standing wall part when the inner door is in the open state. As an example of the curved concave shape of the connection part, in addition to the curved U-shape, a curved J-shape is also available.

[0019] The connecting portion may have a shape other than a curved concave shape. In other words, the connecting portion may be formed in a shape in which a plurality of straight members are connected. Examples of connecting portions that are not curved concave shapes include an L-shape, a shape with two or more bent portions (a U-shape, a part of a polygonal shape), and the like. In this case, the connecting portion can be easily formed.

[0020] The inner door may be configured to open and close in a direction different from the opening and closing direction of the outer door. For example, the outer door may be configured to open and close upward, and the inner door may be configured to open and close sideways. Alternatively, the outer door may be configured to open and close to one of the left and right, and the inner door may be configured to open and close to the other of the left and right. If the outer door and the inner door open and close in the same direction, in order to open the inner door wide, the outer door needs to be opened wider than the inner door. However, in a configuration in which the outer door and the inner door open and close in different directions, the inner door can be opened wide without opening the outer door wide.

[0021] As described above, the fire engine includes a support pillar for rotatably supporting the inner door. Therefore, the fire engine may include a free-standing frame including the support pillar and arranged so as to be movable in and out of the bed. In other words, the support pillar constitutes a part of the free-standing frame. In this way, the free-standing frame including the support pillar can be easily installed.

[0022] The free-standing frame may be configured so that a fire pump can be placed in the inner area of ​​the free-standing frame, which is the rear area of ​​the inner door. A fire pump is one of the larger firefighting tools. By making the free-standing frame large enough to accommodate the fire pump, it can be configured as a unit that can accommodate many firefighting tools.

[0023] The fire engine may be a wagon type vehicle having a roof in the area of ​​the cargo bed. Wagon type vehicles include, for example, vans, minivans, station wagons, etc. In this type of vehicle, it is extremely important to increase the rotation angle of the inner door in order to transport the fire equipment loaded inside the vehicle. Therefore, it is useful to configure it as described above.

[0024] The fire engine may also be a vehicle having a loading platform with an open deck structure. In the loading platform with an open deck structure, small firefighting equipment loaded on the loading platform can be transported regardless of whether the inner door is open or closed. This makes it easy to transport the firefighting equipment. However, it is useful to increase the rotation angle of the inner door to transport large firefighting equipment such as a fire pump. In other words, by adopting a loading platform with an open deck structure, it becomes easy to transport various firefighting equipment, assuming that the rotation angle of the inner door is increased.

[0025] In addition, the outer surface of the inner door may be configured so that a fire suction hose, which is one of the fire fighting tools, can be attached to it. The fire suction hose is the first fire fighting tool to be installed. Therefore, by attaching the fire suction hose to the outer surface of the inner door, it becomes easier to install it first. In particular, by attaching the fire suction hose to the outer surface of the inner door, the entire fire suction hose is exposed simply by opening the outer door. Therefore, it becomes extremely easy to carry out the fire suction hose.

[0026] As another example, the outer door may have a side-opening structure, and the inner surface of the outer door may be configured so that a fire suction hose as one of the fire fighting tools can be attached to it. Even if the fire suction hose is attached to the inner surface of the outer door instead of the outer surface of the inner door, the fire suction hose can be easily removed in the same manner as described above. In this case, fire fighting tools with the same priority as the fire suction hose can be installed on the outer surface of the inner door.

[0027] (Embodiment 1) 1. Configuration of fire engine 1 The configuration of a fire engine 1 according to this embodiment will be described with reference to Figs. 1 to 3. The fire engine 1 will be described by taking as an example a wagon-type vehicle having a ceiling 13 in the area of ​​a cargo bed 10. The fire engine 1 may be a van, a minivan, a station wagon, or the like. In this embodiment, the fire engine 1 is taken as an example of a van with a relatively large cargo compartment. Various fire fighting tools are loaded in the cargo compartment of the fire engine 1.

[0028] This fire engine 1 includes a cargo bed 10, an outer door 20, and a fire equipment mounting unit 30. The area of ​​the cargo bed 10 (luggage compartment) has a ceiling 13, and constitutes an area partitioned from the area outside the vehicle. However, in this embodiment, the cargo bed 10 is located behind the area where the rear passenger seats 40 are located, and there may or may not be a partition between the cargo bed 10 and the area where the rear passenger seats 40 are located.

[0029] The loading platform 10 has an opening 11 on the rear or side of the vehicle. In this embodiment, the opening 11 is located on the rear of the vehicle. Furthermore, the loading platform 10 has a standing wall portion 12 adjacent to the opening 11. In this embodiment, the standing wall portion 12 corresponds to the left and right side wall surfaces. That is, in this embodiment, the rear opening 11 is formed by the left and right standing wall portions 12.

[0030] Although not shown, when the opening 11 is located on the left side of the vehicle, the standing wall portion 12 is, for example, a member constituting the left side of the vehicle or a member constituting the rear side of the vehicle.

[0031] The outer door 20 is configured to open and close the opening 11. The opening and closing direction of the outer door 20 is, for example, upward. In other words, the outer door 20 is configured as a flip-up type. However, the opening and closing direction of the outer door 20 may be lateral, such as a horizontal opening or double door.

[0032] The fire-fighting equipment mounting unit 30 is configured to be able to be installed on the cargo bed 10. In other words, the fire-fighting equipment mounting unit 30 is configured to be able to be accommodated in the cargo room. The fire-fighting equipment mounting unit 30 is configured to be able to mount various fire-fighting equipment and further to be able to accommodate fire-fighting equipment in the internal area. In addition, the fire-fighting equipment mounting unit 30 is configured to be able to stand on its own.

[0033] Here, the firefighting equipment includes a fire suction hose 51, small firefighting equipment such as a shovel 52, a fire pump 53, a fire hose 54, a ladder 55, a generator (not shown), and other firefighting equipment.

[0034] 2. Configuration of the firefighting equipment mounting unit 30 The configuration of the fire-fighting equipment mounting unit 30 will be described mainly with reference to Figures 4 to 5, and secondarily with reference to Figures 1 to 3. The fire-fighting equipment mounting unit 30 includes a self-supporting frame 31 and an inner door 32.

[0035] The self-supporting frame 31 is placed on the loading platform 10. The self-supporting frame 31 is arranged so as to be capable of being carried in and out of the loading platform 10. For example, the self-supporting frame 31 can be mounted on the loading platform 10 while maintaining its external shape, and can also be removed from the loading platform 10 while maintaining its external shape. Additionally, the self-supporting frame 31 can be configured so as to be able to be assembled on the loading platform 10.

[0036] The self-supporting frame 31 is formed, for example, by pillar and beam members that form each side of a rectangular parallelepiped. The self-supporting frame 31 may be provided with auxiliary frames for reinforcement and for mounting firefighting equipment, in addition to main frames that form each side of the rectangular parallelepiped as the external shape. The external shape of the self-supporting frame 31 is not limited to a rectangular parallelepiped, and may be a shape that matches the internal shape of the luggage compartment of the fire engine 1. The self-supporting frame 31 may be formed not only by pillars and beams, but also to have a surface.

[0037] The self-supporting frame 31 includes, as a part of the frame members constituting the frame, a support pillar 31a that rotatably supports the inner door 32. In this embodiment, the support pillar 31a is disposed on the bed 10 and disposed on one side edge of the opening 11 as shown in Figs. 1 to 3. As shown in Fig. 2, the support pillar 31a is disposed, for example, on the left end of the rear of the bed 10 of the fire engine 1. In other words, the support pillar 31a is disposed near the end of the standing wall portion 12 of the bed 10. In this embodiment, the support pillar 31a is disposed near the rear end of the standing wall portion 12 on the left side of the bed 10.

[0038] The inner door 32 is disposed closer to the center of the platform 10 than the outer door 20. In other words, the inner door 32 is located more inward than the outer door 20. The inner door 32 is configured to be rotatable about the support pillar 31a. The inner door 32 is configured to allow firefighting equipment to be installed thereon.

[0039] 1 and 2, the inner door 32 is configured to open and close in a direction different from the opening and closing direction of the outer door 20. For example, when the opening and closing direction of the outer door 20 is upward, the opening and closing direction of the inner door 32 is set to be sideways. Also, when the opening and closing direction of the outer door 20 is sideways, the opening and closing direction of the inner door 32 can be set to be the opposite direction to the opening and closing direction of the outer door 20 among the sides.

[0040] The inner door 32 includes an inner door body 32a and a connection portion 32b. The inner door body 32a is configured so that firefighting equipment can be installed thereon. The inner door body 32a is formed, for example, in an L-shape when viewed from above. One side of the L-shape of the inner door body 32a constitutes the main surface, and the other side of the L-shape constitutes the side edge surface. However, the inner door body 32a may be formed in a simple flat plate shape in addition to the L-shape. For example, as shown in FIG. 2, the inner door body 32a is configured so that a fire suction hose 51 can be installed on the outer surface, and small firefighting equipment 52 such as a shovel can be installed on the inner surface.

[0041] The connection part 32b of the inner door 32 is a member that connects the support pillar 31a of the self-supporting frame 31 and the inner door main body 32a. One end of the connection part 32b is rotatably supported by the support pillar 31a. The other end of the connection part 32b holds the inner door main body 32a. The connection part 32b is connected to, for example, an L-shaped side edge surface of the inner door main body 32a. However, the shape of the fixing part and the fixing method of the inner door main body 32a and the connection part 32b are arbitrary.

[0042] Also, the connection portion 32b is, for example, composed of a plurality of pieces provided separately at different positions in the vertical direction, however, the connection portion 32b may be composed of one piece formed continuously in the vertical direction.

[0043] As shown in FIG. 5, the connection part 32b is formed in a concave shape on the outer surface side of the inner door 32 when viewed from the axial direction of the support 31a. For example, the connection part 32b is formed in a curved concave shape or an angular concave shape on the outer surface side of the inner door 32. In this embodiment, the connection part 32b is formed in a curved U-shaped concave shape as an example of the curved concave shape. Note that other examples of the curved concave shape include a curved J-shaped concave shape and a curved C-shaped concave shape. In addition, examples of the angular concave shape include an L-shaped concave shape, a square U-shaped concave shape (equivalent to a U-shaped concave shape), and a concave shape that is part of a polygon.

[0044] On the other hand, the connection part 32b is formed in a convex shape on the inner side of the inner door 32 when viewed from the axial direction of the support 31a. For example, the connection part 32b is formed in a curved convex shape or an angular convex shape on the inner side of the inner door 32. In this embodiment, the connection part 32b is formed in a curved U-shaped convex shape as an example of a curved convex shape. Note that other examples of the curved convex shape include a curved J-shaped convex shape and a curved C-shaped convex shape. In addition, examples of the angular convex shape include an L-shaped convex shape, an angular U-shaped convex shape (equivalent to a U-shaped convex shape), and a partial polygonal convex shape.

[0045] As will be described later, the concave surface of the connection part 32b becomes the surface facing the end of the standing wall part 12 of the loading platform 10 when the inner door 32 is in the open state. In other words, when the inner door 32 is in the open state, the connection part 32b has a surface formed in a concave shape that faces the end of the standing wall part 12 of the loading platform 10. When the connection part 32b is curved U-shaped as an example of a curved concave shape, the concave surface of the curved U-shape (curved concave surface) forms the surface facing the end of the standing wall part 12 when the inner door 32 is in the open state.

[0046] 3. Example of firefighting equipment loading An example of loading fire fighting equipment on a fire engine 1 will be described with reference to Figs. 1 and 2. However, the loading example described below is merely illustrative, and other loading forms are possible. Here, the fire fighting equipment includes, for example, a fire suction hose 51, small fire fighting equipment 52 such as a shovel, a fire pump 53, a fire hose 54, a ladder 55, a generator (not shown), and other fire fighting equipment.

[0047] The fire suction hose 51, which is one of the fire fighting tools, is attached to the outer surface of the inner door 32, specifically, to the outer surface of the inner door body 32a. The fire suction hose 51 is the first fire fighting tool to be installed at the scene of a fire. Therefore, by being located on the outermost side of the loading platform 10, it can be easily carried out.

[0048] Small fire fighting equipment 52 such as a shovel is attached to the inner surface of the inner door body 32a. Of course, the small fire fighting equipment 52 can also be loaded in the area behind the inner door 32. Some of the small fire fighting equipment is loaded in the area behind the inner door 32.

[0049] The fire pump 53 is disposed in the inner area of ​​the self-supporting frame 31, in the area behind the inner door 32. A rail member 53a for sliding the fire pump 53 is disposed on the lower surface of the fire pump 53. The rail member 53a is configured to be retractable, for example, like a telescope. The fire hose 54 is disposed in the inner area of ​​the fire equipment mounting unit 30, in the area behind the inner door 32. The ladder 55 is placed on the upper surface of the self-supporting frame 31.

[0050] 4. Firefighting equipment removal operation The operation of carrying out the various fire-fighting tools 51 to 55 loaded on the loading platform 10 of the fire-fighting vehicle 1 will be described with reference to Figs.

[0051] As shown in Fig. 6 to Fig. 8, the outer door 20 is opened. In this embodiment, the outer door 20 is a flip-up type, so the opening and closing direction of the outer door 20 is upward. In this state, the outer surface of the inner door 32 is exposed at the opening 11 of the cargo bed 10. In other words, the fire suction hose 51 is fully exposed.

[0052] 9 to 11, the worker removes the fire suction hose 51 from the inner door body 32a and sets it in a predetermined place. In addition to the fire suction hose 51, a fire-fighting tool with a high priority can be attached to the outer surface of the inner door body 32a. In this case, the worker also removes the fire-fighting tool.

[0053] 12 to 14, the worker opens the inner door 32. Then, the worker removes the small fire-fighting equipment 52 attached to the inner surface of the inner door main body 32a as necessary.

[0054] Here, the connection part 32b of the inner door 32 is formed in a concave shape on the outer surface side of the inner door 32. Therefore, when the inner door 32 is in an open state, the concave surface of the connection part 32b of the inner door 32 is positioned so as to face the end of the vertical wall part 12 of the cargo bed 10. Therefore, when the inner door 32 is in an open state, the rotation angle of the inner door main body 32a can be increased while avoiding interference between the connection part 32b and the vertical wall part 12 of the cargo bed 10. As a result, the inner door main body 32a can be opened widely, and the opening width when the inner door 32 is opened can be secured widely. As a result, other firefighting equipment arranged at the back of the inner door 32 can be easily taken out.

[0055] After opening the inner door 32, as shown in Figs. 15 to 17, the worker pulls out and sets up the rail member 53a in order to carry out the fire pump 53. Then, the worker carries out the fire pump 53 to the outside while sliding it on the rail member 53a. After carrying out the fire pump 53, the rail member 53a is stored, and other firefighting equipment such as the fire hose 54 and ladder 55 are carried out as necessary.

[0056] When putting away the fire-fighting equipment, follow the above procedure in reverse.

[0057] 5. Effects According to the fire engine 1 of this embodiment, the inner door 32 provided in the fire engine 1 is configured to include an inner door main body 32a and a connecting portion 32b. One end of the connecting portion 32b is rotatably supported by the support 31a, and the other end holds the inner door main body 32a, and a surface facing the end of the standing wall portion 12 of the cargo bed 10 when the inner door 32 is in an open state is formed in a concave shape. Therefore, when the inner door 32 is in an open state, the rotation angle of the inner door main body 32a can be increased while avoiding interference between the connecting portion 32b and the standing wall portion 12 of the cargo bed 10.

[0058] If the rotation angle of the inner door body 32a is small, the width of the opening 11 of the loading platform 10 may be narrowed by the inner door body 32a. However, the concave connection portion 32b allows the rotation angle of the inner door body 32a to be large. Therefore, the inner door body 32a can be opened widely, and the opening width when the inner door 32 is open can be secured large. As a result, other firefighting tools 53, 54, 55 arranged at the back of the inner door 32 can be easily taken out.

[0059] Therefore, firefighting equipment that needs to be installed first, such as the fire suction hose 51, can be quickly removed from the loading platform 10 of the fire engine 1. Furthermore, other firefighting equipment 53, 54, 55 can also be easily removed.

[0060] The connecting portion 32b has a surface facing the end of the standing wall portion when the inner door 32 is in an open state formed in a curved concave shape. By forming the connecting portion 32b in a curved concave shape, it is possible to increase the rotation angle of the inner door main body 32a while avoiding interference between the connecting portion 32b and the standing wall portion 12 of the loading platform 10 when the inner door 32 is in an open state. Furthermore, by forming the connecting portion 32b in a curved concave shape, it is possible to increase the safety for workers when the inner door 32 is in an open state.

[0061] In particular, it is preferable that the connection portion 32b is formed into a curved U-shape when viewed from the axial direction of the support pillar 31a, and the concave surface of the curved U-shape forms a surface facing the end of the standing wall portion 12 when the inner door 32 is in the open state. As an example of the curved concave shape of the connection portion, in addition to the curved U-shape, a curved J-shape can also provide the same effect.

[0062] The connecting portion 32b may have a shape other than a curved concave shape. That is, the connecting portion 32b may be formed in a shape in which a plurality of straight members are connected. As an example of a case in which the connecting portion 32b is not curved concave, the connecting portion 32b may have an L-shape, or a shape having two or more bends, such as a U-shape with an angle or a part of a polygon. In these cases, the connecting portion 32b can be easily formed.

[0063] The inner door 32 is preferably configured to open and close in a direction different from the opening and closing direction of the outer door 20. If the outer door 20 and the inner door 32 open and close in the same direction, in order to open the inner door 32 wide, the outer door 20 needs to be opened wider than the inner door 32. However, in a configuration in which the outer door 20 and the inner door 32 open and close in different directions, the inner door 32 can be opened wide without opening the outer door 20 wide.

[0064] Moreover, the fire engine 1 of this embodiment is provided with a self-supporting frame 31 arranged so as to be capable of being carried in and out of the loading platform 10, and the self-supporting frame 31 is configured to include a support pillar 31a for rotatably supporting the inner door 32. In other words, the support pillar 31a constitutes a part of the self-supporting frame 31. This makes it easy to install the self-supporting frame 31 including the support pillar 31a.

[0065] The self-supporting frame 31 may be configured so that a fire pump 53 can be placed in the inner area of ​​the self-supporting frame 31, which is the area behind the inner door 32. The fire pump 53 is one of the larger fire-fighting tools. By making the self-supporting frame 31 large enough to accommodate the fire pump 53, it is possible to configure the self-supporting frame 31 as a unit capable of accommodating many fire-fighting tools.

[0066] In addition, the outer surface of the inner door 32 is configured so that a fire suction hose 51, which is one of the fire fighting tools, can be attached. The fire suction hose 51 is the first fire fighting tool to be installed. Therefore, by attaching the fire suction hose 51 to the outer surface of the inner door 32, it becomes easy to install it first. In particular, by attaching the fire suction hose 51 to the outer surface of the inner door 32, the entire fire suction hose 51 is exposed simply by opening the outer door 20. Therefore, it becomes extremely easy to carry out the fire suction hose 51.

[0067] (Embodiment 2) The configuration of the fire engine 2 of this embodiment will be described with reference to Fig. 18 to Fig. 21. Note that, among the symbols used in the second embodiment, the same symbols used in the previous embodiments represent the same components, etc. as those in the previous embodiments, unless otherwise specified.

[0068] The fire engine 2 of this embodiment differs from the fire engine 1 of the first embodiment in that the cargo bed 10 has an open deck structure. Furthermore, the outer door 20 is configured to open sideways. The inner door 32 is configured to open and close in a direction different from the opening and closing direction of the outer door 20. In this embodiment, the outer door 20 opens and closes to the right, and the inner door 32 opens and closes to the left. Therefore, the inner door 32 can be opened wide without the outer door 20 being opened wide. The other configurations are the same as those of the first embodiment.

[0069] In the open deck structure of the loading platform 10, small firefighting equipment loaded on the loading platform 10 can be carried out regardless of whether the inner door 32 is open or closed. This makes it easy to carry out the firefighting equipment. However, it is useful to increase the rotation angle of the inner door 32 to carry out large firefighting equipment such as the fire pump 53. In other words, by adopting the open deck structure of the loading platform 10, on the premise that the rotation angle of the inner door 32 is increased, it becomes easy to carry out various firefighting equipment.

[0070] (Modification of the second embodiment) The configuration of a fire engine 2 as a modification of the second embodiment will be described with reference to Figs. 22 and 23. In the fire engine 3 of this modification, a fire suction hose 51 is attached to the inner surface of the outer door 20. Other fire-fighting equipment with a higher priority can be attached to the outer surface of the inner door 32.

[0071] In this case, as in the above embodiment, it is extremely easy to carry out the fire suction hose 51. Furthermore, on the outer surface of the inner door 32, fire fighting equipment with the same priority as the fire suction hose 51 can be installed.

[0072] This modified embodiment has been described by taking an example of the cargo bed 10 having an open deck structure. However, in the fire engine 1 having a structure in which the cargo bed 10 area has a ceiling 13 as in the first embodiment, if the outer door 20 has a side-opening structure, it is possible to attach a fire suction hose 51 to the inner surface of the outer door 20.
