Description

[Technical field]

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

[0002] 2. Description of the Related Art Fire hydrant devices installed in tunnels on expressways, motorways, and the like are provided with a fire extinguisher storage section in which a fire extinguisher is 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 directed toward the tunnel wall. For this reason, 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 having a fire extinguisher door with a peephole that can be opened and closed freely, and which is characterized in that it is provided with a positioning structure for placing the fire extinguisher in a predetermined position visible from the outside through the peephole."

[0003] [Patent Document 1] JP 2011-41635 A Summary of the Invention [Problem to be solved by the invention]

[0004] When installing a fire hydrant device housing 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 described above, another issue arises as to whether or not it is possible to reduce the depth of the fire hydrant device, i.e., to make it thinner. The problem of making the fire hydrant device thinner is particularly problematic in the case of shield tunnels, where the fire hydrant device cannot be installed by simply cutting out a box and embedding it in the tunnel. In this regard, the fire hydrant device of Patent Document 1 does not consider the problem of thinning at all.

[0005] When the inventor 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, he realized that while a transparent acrylic plate or the like is usually attached to the observation window, the frame members for attaching the acrylic plate or the like prevent the device from being made thinner. Such problems also exist with fire extinguisher boxes that house fire extinguishers.

[0006] The present invention has been made to solve such problems, and has an object to provide a fire hydrant device and a fire extinguisher box that allow the user to reliably check from the outside whether a fire extinguisher is stored inside. 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 thin. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The fire hydrant device 1 of this embodiment comprises a fire extinguisher storage section 5 (see Figure 3) provided within a housing 3, a fire extinguisher door 7 that can be opened and closed on the front side of the fire extinguisher storage section 5, an opening window section 9 provided on the front side of the fire extinguisher door 7, and a transparent panel 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 generally described, and then the fire extinguisher storage section 5 and the fire extinguisher door 7, which are characteristic parts of the present invention, will be described in detail.

[0016] <Overall configuration of fire hydrant equipment> 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 side 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 be opened and closed. 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 housing section 15 for storing a hose 13 wound inward is provided within the housing 3. Also, a piping system 21 having a maintenance valve, etc. is provided to the right of the hose housing section 15.

[0018] <Front panel> The front panel 19 is provided on the front of the housing 3 and is open at a location located forward of the central opening 23 of the hose accommodating section 15. A tilt-forward door 17 is attached to this opening 19a so as to be able to open and close it, and a fire extinguisher door 7 is provided on the left side of the front panel 19 so as to be able to open and close it.

[0019] <Tilt-forward door> The tilt-forward door 17 has a horizontally long rectangular shape and is made of a metal plate, 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 is provided with a rotation shaft 24 at both ends of the lower side, and can open the opening 19a from a closed state by approximately 180° as shown in FIG. On the inner surface of the tilt-forward door 17, there is provided a fire nozzle holding portion 27 that detachably holds the fire nozzle 25, and an operating lever 29 that opens and closes a fire hydrant valve provided in the fire water supply pipe that supplies fire 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 portions 31 arranged to sandwich the central opening 23, and a pair of horizontal side portions 33 arranged to connect the upper ends and lower ends of the pair of vertical side portions 31. A pair of band plate portions 35 that are approximately L-shaped in a plan view are provided on the pair of vertical side portions 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 area> 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 mounting stand 39 on which two fire extinguishers 37 can be placed in an upright state side-by-side. In the present invention, the depth of the housing 3 is shortened as much as possible, aiming at a so-called thin design, and the depth of the fire extinguisher storage section 5 is set to be substantially the same as the diameter of the stored fire extinguisher 37, as shown in Fig. 3. Specific examples of the depth dimension of the fire extinguisher storage section 5 will be described later.

[0022] In Fig. 3, the dotted and solid circles indicate the locations where the fire extinguishers 37 are placed, and the dotted and solid circles indicate the case where the 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 in which the fire extinguishers 37 are placed is the area surrounded by the solid and dotted lines, and for example, when 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, which will be described 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 band-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 side edges.

[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 the fixing piece portion 47 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 to press the transparent plate 11.

[0025] As shown in FIG. 3, the pressing piece 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 the present embodiment is adapted to store two fire extinguishers 37, the pressing pieces 57 are provided at both ends and in 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 extremely shorten the depth dimension of the storage section for fire extinguisher 37, which is the deepest of the members stored in fire hydrant device 1, and to achieve a thin housing 3, the relationship A≦C is set, where A is the distance from pressing piece 57 to back surface 59 of fire extinguisher storage section 5, and C is the maximum diameter of fire extinguisher 37. For this reason, if the maximum diameter of fire extinguisher 37 is located at the position of pressing piece 57, fire extinguisher 37 cannot be stored. Therefore, pressing piece 57 is not provided at the location where the maximum diameter of fire extinguisher 37 is located. However, in order for the fire extinguisher 37 to be stored, if the distance from the point where the pressing piece 57 is not provided, i.e., the point where the transparent panel 11 is located, to the back surface 59 of the fire extinguisher storage section 5 is B, then the relationship C≦B holds. In other words, the dimensions are set so that A≦C≦B, thereby making the depth dimension of the fire extinguisher 37 extremely short and achieving a slim housing 3.

[0027] In the fire hydrant device 1 of this embodiment configured as described above, the pressing piece portions 57 of the mounting member that attaches the transparent plate 11 to the inner side of the fire extinguisher door 7 are provided intermittently in the axial direction of the mounting member, so that the pressing piece portions 57 are not present at the location where the maximum diameter of the fire extinguisher 37 is located when the fire extinguisher 37 is placed.This means that 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 FIG. 3, when the fire extinguisher 37 is placed in the fire extinguisher storage section 5, the maximum diameter of the fire extinguisher 37 is positioned at the point where there is no pressing piece portion 57, and the mounting member serves as a guide for positioning the fire extinguisher 37 when it is placed. Therefore, unlike the conventional example, there is no need to provide a separate indicator for the position where the fire extinguisher 37 is placed. 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 mounted in the fire extinguisher storage section 5, but when three fire extinguishers are to be mounted, the upper side mounting member 41 and the lower side 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. When four fire extinguishers 37 are to be mounted, the upper side mounting member 41 and the lower side 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] In addition, in the above example, the mounting members were 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 members of the present invention are not limited to this, and may be rectangular frame-like bodies that surround 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] In addition, 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 a shape of the mounting member provided on 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, in which case the rear surface of the fire extinguisher storage unit 5 may be protruded toward the rear surface. This point will be specifically described below.

[0032] For example, when installing a fire hydrant on a guard's passage in a shield tunnel, it is possible to provide a stand on the shield tunnel wall and erect the fire hydrant on the stand. In such a case, since 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 protruded to the rear side in the area corresponding to this space, so that the rear surface 59 of the fire extinguisher storage section 5 can be protruded slightly to the rear side as shown in Fig. 6. The protruding area is not the entire casing 3, but at least the rear surface of the fire extinguisher storage section 5 where the maximum diameter of the fire extinguisher is located, and more specifically, it is within about 1 / 2 of the range from the bottom in the height direction of the fire extinguisher storage section 5. In addition, the portion protruding toward 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 for processing 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 design of the mounting member provided on the inner side 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, the above explanation has been given of a fire hydrant device 1 that stores a fire hose 13 inside the housing 3, but the same can also be applied to a fire extinguisher box that stores only a fire extinguisher inside the housing. [Explanation of symbols]
