Description

[Technical Field]

[0001] The present invention relates to a fire hydrant device and a fire extinguisher box that are installed in, for example, a tunnel of a highway. [Background technology]

[0002] 2. Description of the Related Art Fire hydrant devices installed in tunnels such as expressways and motorways are provided with a fire extinguisher storage compartment in which fire extinguishers are stored in an upright position. The work of checking whether a fire extinguisher is stored in the fire extinguisher storage section is planned to be carried out, for example, while driving an inspection vehicle with its light shining on the tunnel wall.To do this, it is necessary for the fire extinguisher to be placed in a fixed position.To meet this requirement, for example, Patent Document 1 proposes a ``tunnel fire extinguisher device in which a fire extinguisher is stored in a housing with a fire extinguisher door with a peephole that can be opened and closed freely, and which is characterized by having a positioning structure that positions the fire extinguisher in a fixed position that can be seen from the outside through the peephole.''

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-41635 Summary of the Invention [Problem to be solved by the invention]

[0004] When installing a fire hydrant device containing a fire extinguisher inside a tunnel, in addition to the issue of whether or not the presence or absence of the fire extinguisher can be reliably confirmed from the outside, as mentioned above, another issue is whether or not it is possible to reduce the depth of the fire hydrant device, i.e., to make it thinner. The issue of making fire hydrant devices thinner is particularly problematic in the case of shield tunnels, where it is not possible to install the device by cutting out a box and embedding it inside. In this regard, the fire hydrant device of Patent Document 1 does not consider the issue of thinning at all.

[0005] The inventors considered how to make a fire hydrant device that allows the presence or absence of a fire extinguisher to be checked from the outside thinner, and realized that while a transparent acrylic plate or the like is usually attached to the viewing window, the frame members for attaching the acrylic plate or the like prevent the device from being made thinner. Such problems also exist in fire extinguisher boxes that house fire extinguishers.

[0006] The present invention has been made to solve such problems, and aims to provide a fire hydrant device and a fire extinguisher box that allow reliable confirmation from the outside of whether or not a fire extinguisher is stored. In addition to the above object, another object of the present invention is to provide a fire hydrant device and a fire extinguisher box that can be made thinner. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0015] The fire hydrant device 1 of this embodiment comprises a fire extinguisher storage section 5 (see Figure 3) provided within the housing 3, a fire extinguisher door 7 that can be opened and closed on the front of the fire extinguisher storage section 5, an opening window section 9 provided on the front of the fire extinguisher door 7, and a transparent plate 11 provided to cover the opening window section 9. However, in addition to the fire extinguisher storage section 5, the housing 3 of the fire hydrant device 1 is also provided with a hose storage section 15 that stores a fire hose 13, a forward-tilting door 17 that opens and closes to pull out the hose 13, and the like. In the following, the overall configuration of the fire hydrant device 1 will be outlined, followed by a detailed description of the fire extinguisher storage section 5 and the fire extinguisher door 7, which are characteristic features of the present invention.

[0016] <Overall configuration of the fire hydrant system> As shown in Figures 1 and 2, the fire hydrant device 1 comprises a box-shaped housing 3, a front panel 19 having an opening 19a provided on the front surface of the housing 3, and a tilt-forward door 17 provided in the opening 19a of the front panel 19 so as to be able to open and close. In this specification, the term "front" indicating a position in the fire hydrant device 1 refers to the front panel 19 side, and "rear" refers to the rear panel side. Each component will be described in detail below.

[0017] <Case> As shown in Figures 1 and 2, the housing 3 is in the shape of a rectangular box, and a hose storage section 15 is provided inside the housing 3 to store the hose 13 wound inward, and a piping system 21 having a maintenance valve, etc. is provided on the right side of the hose storage section 15.

[0018] <Front panel> The front panel 19 is provided on the front of the housing 3 and has an opening in the area located in front of the central opening 23 of the hose storage section 15. A tilt-forward door 17 is attached to this opening 19a so that it can be opened and closed, and a fire extinguisher door 7 is provided on the left side of the front panel 19 so that it can be opened and closed.

[0019] <Tilt-forward door> The tilt-forward door 17 is made of a metal plate and has a horizontally long rectangular shape, and is attached to the opening 19a of the front panel 19 so as to be able to open and close, as described above. The tilt-forward door 17 has a rotation shaft 24 provided at both ends of the lower side, and can open the opening 19a from a closed state by approximately 180 degrees as shown in FIG. On the inner side of the forward-tilting door 17, there is provided a fire extinguishing nozzle holding portion 27 that detachably holds the fire extinguishing nozzle 25, and an operating lever 29 that opens and closes the fire hydrant valve installed in the fire extinguishing water supply pipe that supplies fire extinguishing water to the hose 13.

[0020] <Hose housing> As shown in Figures 1 and 2, the hose accommodating section 15 has a pair of vertical side sections 31 erected on either side of the central opening 23, and a pair of horizontal side sections 33 arranged to connect the upper ends and lower ends of the pair of vertical side sections 31, and a pair of band plate sections 35 that are approximately L-shaped in plan view are provided on the pair of vertical side sections 31 of this frame body. The hose 13 is wound inward in the space between the pair of band plate portions 35 and the rear panel (the rear surface of the housing 3).

[0021] <Fire extinguisher storage compartment> The fire extinguisher storage section 5 is formed in the left area in Figures 1 and 2 inside the housing 3. As shown in Figure 3, the fire extinguisher storage section 5 is provided with a fire extinguisher stand 39 on which two fire extinguishers 37 can be placed in an upright, side-by-side position. The present invention aims to make the depth of the housing 3 as short as possible, that is, to make it thinner, and the depth of the fire extinguisher storage compartment 5 is set to be approximately the same as the diameter of the stored fire extinguisher 37, as shown in Figure 3. Specific examples of the depth dimension of the fire extinguisher storage compartment 5 will be described later.

[0022] In Figure 3, the dotted and solid circles indicate the locations where fire extinguishers 37 are placed, and the dotted and solid circles indicate the case where two fire extinguishers 37 are placed closest to each other (in a state where the two fire extinguishers 37 are abutting each other). The space where fire extinguishers 37 are placed is the area surrounded by the solid and dotted lines, and for example, if the fire extinguisher 37 on the left side of the figure is placed at the dotted line position, the fire extinguisher 37 on the right side of the figure can be placed within the range from the dotted line position to the solid line position.

[0023] In relation to the extremely narrow depth, the structure of the inner side of the fire extinguisher door 7 is unique, and this will be explained below with reference to FIGS. In order to make the fire extinguisher 37 inside visible from the outside, the fire extinguisher door 7 has an opening window 9 extending downward from approximately the center in the height direction, and a transparent plate 11 is installed on the inner side of the opening window 9 so as to cover it. In order to attach the transparent plate 11 to the inner surface of the fire extinguisher door 7, as shown in Figure 4, a strip-shaped upper edge mounting member 41 is provided on the upper edge of the opening window portion 9, a lower edge mounting member 43 is provided on the lower edge, and side edge mounting members 45 are provided on both sides.

[0024] The upper edge mounting member 41 and the lower edge mounting member 43 correspond to the mounting members of the present invention, and since the upper edge mounting member 41 and the lower edge mounting member 43 have the same shape, the lower edge mounting member 43 will be used as an example for the following explanation. As shown in Figure 5, the lower edge mounting member 43 has a fixing piece portion 47 that fixes the lower edge mounting member 43 to the inner surface of the fire extinguisher door 7, and a clamping piece portion 49 that clamps the transparent plate 11 between it and the inner surface of the fire extinguisher door 7. The clamping piece 49 has a rising piece 53 that rises from the fixed piece 47 via a first bent portion 51, and a pressing piece 57 that extends in a direction parallel to the fixed piece 47 via a second bent portion 55 and presses the transparent plate 11.

[0025] As shown in FIG. 3, the pressing piece 57 is not provided at a position 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 pressing pieces 57 are provided at both ends and the center. The reason why the pressing piece 57 is not provided at the portion where the maximum diameter of the fire extinguisher 37 is located is as follows.

[0026] In this embodiment, in order to achieve a slim housing 3 by extremely shortening the depth dimension of the storage section for fire extinguisher 37, which is the deepest of the components stored in the fire hydrant device 1, the relationship A≦C is set, where A is the distance from the holding piece 57 to the back surface 59 of the fire extinguisher storage section 5 and C is the maximum diameter of the fire extinguisher 37. For this reason, 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 57 is not provided in the portion where the maximum diameter of the fire extinguisher 37 is located. However, in order for the fire extinguisher 37 to be able to be stored, if the distance from the point where the pressing piece 57 is not provided, i.e., the point where the transparent plate 11 is located, to the back surface 59 of the fire extinguisher storage section 5 is B, then the relationship C≦B holds. That is, the dimensions are set to satisfy the relationship A≦C≦B, thereby making the depth dimension of the fire extinguisher 37 extremely short and realizing a slim housing 3.

[0027] In the fire hydrant device 1 of this embodiment configured as described above, the retaining piece portions 57 of the mounting member that attaches the transparent plate 11 to the inner side of the fire extinguisher door 7 are arranged intermittently in the axial direction of the mounting member, so that the retaining piece portions 57 are not present in the area where the maximum diameter of the fire extinguisher 37 is located when the fire extinguisher 37 is placed.As a result, there is nothing to get in the way when the fire extinguisher 37 is placed, and a thin design can be achieved in which the depth of the fire extinguisher storage section 5 is approximately equal to the maximum diameter of the fire extinguisher 37.

[0028] Furthermore, as shown in Figure 3, when placing the fire extinguisher 37 in the fire extinguisher storage section 5, the maximum diameter of the fire extinguisher 37 is positioned at the point where the pressing piece portion 57 is not present, and the mounting member serves as a guide for positioning the fire extinguisher 37 when placing it. Therefore, unlike the conventional example, there is no need to provide a separate indicator to indicate the position where the fire extinguisher 37 is placed, and by placing the fire extinguisher 37 in the appropriate position, the fire extinguisher 37 stored inside can be reliably seen from the outside.

[0029] In the above example, two fire extinguishers 37 are placed in the fire extinguisher storage section 5, but if, for example, three fire extinguishers are to be placed, the upper edge mounting member 41 and the lower edge mounting member 43 may be provided with clamping piece portions 49 at both ends and with clamping piece portions 49 intermittently provided at two locations in the middle portion sandwiched between the ends. Furthermore, if four fire extinguishers 37 are to be placed, the upper edge mounting member 41 and the lower edge mounting member 43 may be provided with clamping piece portions 49 at both ends and with clamping piece portions 49 intermittently provided at three locations in the middle portion sandwiched between the ends.

[0030] Furthermore, in the above example, the mounting member was composed of four straight plate-like bodies: an upper edge mounting member 41, a lower edge mounting member 43, and a pair of side edge mounting members 45. However, the mounting member of the present invention is not limited to this, and may be a rectangular frame-like body that surrounds the opening window portion 9, or a combination of an L-shaped body in which the upper edge and one side edge are integrated, and an L-shaped body in which the lower edge and the other side edge are integrated.

[0031] Furthermore, the above description is about ensuring the depth of the fire extinguisher storage section 5 without changing the shape of the housing 3 itself by devising the shape of the mounting member attached to the inner side of the fire extinguisher door 7. However, depending on the installation location of the fire hydrant device, there may be space behind the fire extinguisher storage unit 5, and in such cases, the back of the fire extinguisher storage unit 5 may be configured to protrude toward the rear side. This point will be specifically described below.

[0032] For example, when installing a fire hydrant above a guard's passage in a shield tunnel, a stand may be provided on the shield tunnel wall, and the fire hydrant may be erected on the stand. In such a case, because the shield tunnel wall is curved, there is a small space between the lower part of the fire hydrant and the wall. Therefore, the casing of the fire hydrant can be made to protrude rearward in a portion corresponding to this space. As shown in Figure 6, the rear surface 59 of the fire extinguisher storage unit 5 may be made to protrude slightly rearward. The protruding portion does not extend over the entire casing 3, but rather over at least the rear surface of the fire extinguisher storage unit 5 where the maximum diameter of the fire extinguisher is located. More specifically, it extends over approximately half of the height of the fire extinguisher storage unit 5 from the bottom. In addition, the portion protruding from the rear side may include not only the fire extinguisher storage section 5 but also the lower part of the hose storage section 15, taking into consideration the effort required to process the housing 3, etc. In this way, by slightly protruding the rear surface 59 of the fire extinguisher storage section 5 toward the rear side, combined with the ingenious shape of the mounting member provided on the inner surface of the fire extinguisher door 7, it is possible to store the fire extinguisher 37 without increasing the depth of the entire housing 3.

[0033] Furthermore, although the above explanation has been given of a fire hydrant device 1 that stores a fire hose 13 inside the housing 3, it can also be applied in the same way to a fire extinguisher box that stores only a fire extinguisher inside the housing. [Explanation of symbols]
