When installing a fire hydrant system containing a fire extinguisher inside a tunnel, in addition to the problem of whether or not the presence or absence of a fire extinguisher can be reliably confirmed from the outside as mentioned above, there is also the issue of making the fire hydrant system thinner by shortening its depth. There is also the question of whether or not this can be achieved.
The problem of making the fire hydrant device thinner becomes a particular problem in the case of a shield tunnel where the fire hydrant device cannot be installed by cutting out the box and embedding it.
In this regard, in the fire hydrant device of Patent Document 1, no consideration has been given to the issue of thinning.

In the following, after an overview of the overall configuration of the fire hydrant device 1, the fire extinguisher storage section 5 and the fire extinguisher door 7, which are the characteristic parts of the present invention, will be explained in detail.

<Overall configuration of fire hydrant device>
As shown in FIGS. 1 and 2, the fire hydrant device 1 includes a box-shaped housing 3, a front panel 19 having an opening 19a provided at the front of the housing 3, and an opening 19a in the front panel 19. It is provided with a forward-tilting door 17 which is provided so as to be openable and closable.
In this specification, the term "front" indicating the position in the fire hydrant device 1 refers to the front panel 19 side, and the term "back" refers to the rear panel side.
Each configuration will be explained in detail below.

<Housing>
As shown in FIGS. 1 and 2, the casing 3 has a rectangular box shape, and a hose accommodating portion 15 for storing the inwardly wound hose 13 is provided in the casing 3. A piping system 21 having a maintenance valve and the like is provided on the right side of the housing section 15.

<Front panel>
The front panel 19 is provided on the front surface of the housing 3, and is open at a portion located in front of the central opening 23 of the hose accommodating portion 15. A forward-tilting door 17 is attached to the front panel 19 so as to be able to open and close this opening 19a. A fire extinguisher door 7 is provided on the left side of the front panel 19 so as to be openable and closable.

<Forward tilting door>
The forward-tilting door 17 has a horizontally long rectangular shape made of a metal plate, and is attached so as to be able to open and close the opening 19a of the front panel 19 as described above.
The forward-tilting door 17 is provided with rotation shafts 24 at both ends of the lower side, and the opening 19a can be opened approximately 180 degrees from the closed state as shown in FIG.
On the inner side of the forward-tilting door 17, there is a fire extinguishing nozzle holding part 27 that removably holds a fire extinguishing nozzle 25, and a fire hydrant valve provided in a fire extinguishing water supply pipe that supplies fire extinguishing water to the hose 13. An operating lever 29 is provided.

<Hose housing section>
As shown in FIGS. 1 and 2, the hose accommodating portion 15 connects a pair of vertical sides 31 that are erected across the central opening 23, and connects the upper ends and lower ends of the pair of vertical sides 31 to each other. A pair of horizontal side portions 33 are provided as shown in FIG.
The hose 13 is wound inwardly in the space between the pair of band plate portions 35 and the back panel (back surface of the housing 3).

<Fire extinguisher storage section>
The fire extinguisher storage section 5 is formed in the left side area in FIGS. 1 and 2 inside the housing 3. As shown in FIG. 3, the fire extinguisher storage section 5 is provided with a fire extinguisher mounting table 39 on which two fire extinguishers 37 can be placed side by side in an upright state.
In the present invention, the depth of the casing 3 is made as short as possible, so-called thinning, and as shown in FIG. The dimensions are set. A specific example of the depth dimension of the fire extinguisher storage section 5 will be described later.

In addition, in FIG. 3, the dotted line and the solid line circles indicate the placement locations of the fire extinguishers 37, and the dotted lines and the solid lines indicate the places where the two fire extinguishers 37 are placed closest to each other (the two fire extinguishers 37 are placed closest to each other). This figure shows the case where they are placed (in contact with each other). The space in which the fire extinguisher 37 is placed is an area surrounded by a solid line and a broken line. For example, if the fire extinguisher 37 on the left side of the figure is placed at the position indicated by the broken line, the fire extinguisher 37 on the right side of the figure is placed at the position indicated by the broken line. It can be placed within the range of the position indicated by the solid line.

There is a feature in the structure of the inner surface of the fire extinguisher door 7 that is related to the extremely narrow depth, and this point will be explained below based on FIGS. 3 and 4.
In order to make the fire extinguisher 37 inside visible from the outside, the fire extinguisher door 7 is provided with an opening window 9 extending downward from approximately the center in the height direction, and a transparent plate is provided to cover the opening window 9. 11 is installed on the inner surface side of the opening window portion 9.
In order to attach the transparent plate 11 to the inner surface of the fire extinguisher door 7, as shown in FIG. A mounting member 43 and side mounting members 45 provided on both sides are provided.

The upper side attachment member 41 and the lower side attachment member 43 correspond to the attachment members of the present invention, and since the upper side attachment member 41 and the lower side attachment member 43 have the same shape, the lower side attachment member 43 will be described below as an example.
As shown in FIG. 5, the lower side mounting member 43 is sandwiched between a fixing piece 47 that fixes the lower side mounting member 43 to the inner surface of the fire extinguisher door 7 and the transparent plate 11 on the inner surface of the fire extinguisher door 7. It has a clamping piece part 49.
The clamping piece 49 has a rising piece 53 that rises from the fixed piece 47 via the first bent part 51 and extends in a direction parallel to the fixed piece 47 via the second bent part 55 to form a transparent plate. 11 is provided.

As shown in FIG. 3, the holding piece portion 57 is not provided at a portion where the maximum diameter of the fire extinguisher 37 is located when the fire extinguisher 37 is placed.
Specifically, since the fire extinguisher storage section 5 of this embodiment stores two fire extinguishers 37, the presser pieces 57 are provided at both ends and at the center.
The reason why the holding piece portion 57 is not provided at the portion where the maximum diameter of the fire extinguisher 37 is located is as follows.

In this embodiment, the depth dimension of the storage part of the fire extinguisher 37, which is the deepest among the members stored in the fire hydrant device 1, is extremely shortened to realize a thinner housing 3. When the distance to the back surface 59 of the fire extinguisher storage section 5 is A, and the maximum diameter of the fire extinguisher 37 is C, the relationship is set to A≦C. Therefore, if the maximum diameter of the fire extinguisher 37 is located at the position of the holding piece 57, the fire extinguisher 37 cannot be stored. Therefore, the holding piece portion 57 is not provided at the portion where the maximum diameter of the fire extinguisher 37 is located.
However, in order for the fire extinguisher 37 to be stored, if the distance from the location where the holding piece 57 is not provided, that is, the location where the transparent plate 11 is located, to the back surface 59 of the fire extinguisher storage section 5 is B, then C≦B. are in a relationship.
In other words, each dimension is set in the relationship of A≦C≦B, thereby making the depth dimension of the fire extinguisher 37 extremely short and realizing a thinner housing 3.

In the fire hydrant device 1 of the present embodiment configured as described above, the holding pieces 57 of the mounting member for attaching the transparent plate 11 to the inner surface of the fire extinguisher door 7 are provided intermittently in the axial direction of the mounting member. Since the holding piece 57 is not located in the area where the maximum diameter of the fire extinguisher 37 is located when the fire extinguisher 37 is placed, there is nothing that will get in the way when the fire extinguisher 37 is placed. , the depth of the fire extinguisher accommodating portion 5 can be made substantially equal to the maximum diameter of the fire extinguisher 37, which makes it possible to achieve a thinner profile.

In addition, as shown in FIG. 3, when placing the fire extinguisher 37 in the fire extinguisher storage section 5, the maximum diameter of the fire extinguisher 37 should be at a location where the holding piece 57 is not present, so that the mounting The member serves as a positioning index when placing the fire extinguisher 37.
Therefore, unlike the conventional example, there is no need to separately provide an indicator for the position where the fire extinguisher 37 is placed, and by placing the fire extinguisher 37 at the position, the fire extinguisher 37 stored inside can be accessed from the outside. Can be reliably seen.

Note that in the above example, two fire extinguishers 37 are placed in the fire extinguisher storage section 5, but if three fire extinguishers are placed, for example, the upper side mounting member 41 and the lower side mounting member 43, The clamping pieces 49 may be provided at both ends, and the clamping pieces 49 may be provided intermittently at two locations in the middle between the both ends. In addition, when four fire extinguishers 37 are mounted, the upper side mounting member 41 and the lower side mounting member 43 are provided with clamping pieces 49 at both ends, and clamping pieces 49 are provided at three locations in the middle between both ends. 49 may be provided intermittently.

Further, in the above example, the mounting member was composed of four linear plate-like members, the upper side mounting member 41, the lower side mounting member 43, and a pair of side mounting members 45, but the present invention The mounting member is not limited to this, but may include a rectangular frame-shaped one that surrounds the opening window 9, an L-shaped one in which the upper side and one side are integrated, and a lower side and the other side. It may be a combination of L-shaped parts with integrated sides.

In addition, the above explanation shows that by devising the shape of the mounting member provided on the inner surface of the fire extinguisher door 7, the depth of the fire extinguisher storage section 5 can be secured without changing the shape of the housing 3 itself. It is something.
However, depending on the installation location of the fire hydrant device, there may be space on the back side of the fire extinguisher storage section 5, and in such cases, the back surface of the fire extinguisher storage section 5 should be made to protrude toward the back side. Good too. This point will be specifically explained below.

For example, when installing a fire hydrant device on the guard passage in a shield tunnel, it is possible to install a pedestal on the wall side of the shield tunnel and erect the hydrant device on the pedestal. Since the wall surface is curved, there is a small space between the lower part of the fire hydrant device and the wall surface. Therefore, as for the part corresponding to this space, the casing of the fire hydrant device can be made to protrude to the back side, so that the back face 59 of the fire extinguisher storage section 5 is made to slightly protrude to the back side, as shown in FIG. You can do it like this. The protruding part is not the entire housing 3, but at least the back side of the fire extinguisher storage part 5 where the maximum diameter of the fire extinguisher is located, and more specifically, the part that protrudes from the bottom in the height direction of the fire extinguisher storage part 5. The range is 1/2.
Note that the portion that is projected toward the back side may include not only the fire extinguisher storage section 5 but also the lower part of the hose storage section 15 in consideration of the labor involved in processing the casing 3.
In this way, by making the back surface 59 of the fire extinguisher storage section 5 slightly protrude toward the back side, together with devising the shape of the mounting member provided on the inner surface of the fire extinguisher door 7, the entire housing 3 can be The fire extinguisher 37 can be stored without increasing the depth of the fire extinguisher 37.

In addition, although the above description has been made regarding the fire hydrant device 1 that stores the fire extinguishing hose 13 inside the housing 3, the same applies to a fire extinguisher box that stores only a fire extinguisher inside the housing. I can do it.
