[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0016] In addition, in this specification and drawings, when multiple identical components are to be described separately, alphabets or the like may be added to the end of the reference numerals. On the other hand, when there is no need to distinguish between multiple identical components, the alphabets or the like may be omitted and a description common to all of the multiple identical components may be given.

[0017] <1. Embodiment> First, with reference to Figs. 1 and 2, an example of the arrangement of a housing 10 according to an embodiment of the present invention and transitions between a fully closed state and a fully open state will be described.

[0018] FIG. 1 is a diagram showing an example of the arrangement of a housing 10 according to an embodiment of the present invention.

[0019] The lower right side of Fig. 1 shows a front view of the housing 10 in a fully closed state as seen from the roadway RW side. The lower left side of Fig. 1 shows a side view of the housing 10 in a fully closed state. The upper right side of Fig. 1 shows a front view of the housing 10 in a fully open state as seen from the roadway RW side. Also, the upper left side of Fig. 1 shows a side view of the housing 10 in a fully open state. Hereinafter, the surface of the housing 10 facing the roadway RW will be referred to as the front, and the surface of the housing 10 facing the passage PW will be referred to as the back.

[0020] 1, the housing 10 according to the present embodiment is installed, for example, in a tunnel or the like, between a roadway RW and a passageway PW parallel to the roadway RW. The housing 10 may be installed on a stand 90.

[0021] The passageway PW is provided for people to pass through and perform work. The work includes, for example, firefighting and maintenance work. The passageway includes not only the passageway for performing the work, but also the passageway for evacuation.

[0022] FIG. 2 is a diagram for explaining the transition of the housing 10 according to this embodiment from a fully closed state to a fully open state.

[0023] A front view showing the transition of housing 10 from the fully closed state to the fully open state is shown on the right side of Fig. 2. A rear view showing the transition of housing 10 from the fully closed state to the fully open state is shown on the left side of Fig. 2. Also, a side view showing the transition of housing 10 from the fully closed state to the fully open state is shown in the center of Fig. 2.

[0024] The housing 10 according to this embodiment includes an outer box 100, an inner box 200 that can be stored inside the outer box 100, and an inner box 300 that can be stored inside the inner box 200 and in which tools used for firefighting activities are placed.

[0025] The fire extinguisher 80 is an example of an instrument used in firefighting activities.

[0026] The upper surface of the housing 10 according to this embodiment is formed by a part of the inner box 300. In other words, the upper surface of the housing 10 is the upper surface of the inner box 300.

[0027] A handle 310 is provided on the top surface of the inner box 300 according to this embodiment. An operator (a person engaged in firefighting activities, a maintenance worker, etc.) can hold the handle 310 from the roadway RW side or the passage PW side, for example, and pull the inner box 300 upward to bring the housing 10 into a fully open state (a state in which the inner box 300 is located at the uppermost end of the movable area).

[0028] The inner box 200 (front side) in this embodiment functions as a lid that closes the front opening 120 formed on the front side of the outer box 100 when the housing 10 is in a fully closed state (when the inner box 300 is located at the bottom end of the movable area).

[0029] Also, one of the features of the middle box 200 according to this embodiment is that it moves downward in conjunction with the upward movement of the inner box 300.

[0030] Due to the above-mentioned features, when the housing 10 is in the fully open state, the front opening 120 of the outer box 100 is exposed.

[0031] FIG. 3 is a diagram showing an example of how the fire extinguisher 80 according to this embodiment is removed.

[0032] When the housing 10 is fully open, the fire extinguisher 80 placed in the inner box 300 protrudes from the surface of the passage PW, so that an operator can easily remove the fire extinguisher 80 from the passage PW side, as shown on the left side of Figure 3.

[0033] Furthermore, as described above, when the housing 10 is fully open, the front opening 120 of the outer box 100 is opened, so that the operator can easily remove the fire extinguisher 80 from the roadway RW side through the front opening 120, as shown on the right side of Figure 3.

[0034] When changing the housing 10 from the fully open state to the fully closed state, the operator only needs to grasp the handle 310 and push the inner box 300 downward.

[0035] In conjunction with the downward movement of the inner box 300 by the above operation, the inner box 200 moves upward, thereby closing the front opening 120 of the outer box 100.

[0036] As described above, the inner box 200 according to this embodiment moves in the opposite direction to the inner box 300 as the inner box 300 moves up and down.

[0037] When a configuration such as a handle or a recess is provided on the surface of the inner box 200 on the side of the front opening 120, the operator can also use this configuration to move the inner box 200 up and down.

[0038] In this case, the inner box 300 according to this embodiment moves in the opposite direction to the inner box 200 as the inner box 200 moves up and down.

[0039] The configuration for realizing the above-mentioned interlocking of middle box 200 and inner box 300 will be described in detail below.

[0040] FIG. 4 is a diagram for explaining a configuration example of the outer box 100 according to the present embodiment.

[0041] FIG. 4 shows a top view, a bottom view, a front view, a side view, a rear view, a cross-sectional view taken along lines AA, BB, and CC of the outer box 100.

[0042] As shown in FIG. 4, the outer box 100 according to this embodiment has an upper opening 110 on the upper surface and a front opening 120 on the front surface.

[0043] The top opening 110 is a structure that allows the inner box 300 to move up and down. When the inner box 300 according to this embodiment moves upward through the top opening 110, the fire extinguisher 80 is opened.

[0044] The upper surface, lower surface, front surface, sides, and rear surface of the outer box 100 excluding the upper opening 110 and the front opening 120 are formed of metal plates (indicated by dots).

[0045] Additionally, the outer box 100 according to this embodiment includes two gear mounting hardware 130A and 130B extending downward from the top surface.

[0046] Two gears, 140A1 and 140A2, are attached to the gear mounting bracket 130A. Two gears, 140B1 and 140B2, are attached to the gear mounting bracket 130B.

[0047] Gears 140A1 and 140A2 fit with inner box rail 240A (see FIG. 5) provided on inner box 200 and inner box rail 340A (see FIG. 6) provided on inner box 300.

[0048] Similarly, gears 140B1 and 140B2 mate with inner box rail 240B (see FIG. 5) provided on inner box 200 and inner box rail 340B (see FIG. 6) provided on inner box 300.

[0049] The gear 140 according to this embodiment is an example of a movable part. The movable part is not limited to the gear 140 and may be any member capable of interlocking the middle box 200 and the inner box 300.

[0050] Additionally, outer box 100 includes rollers 150A and 150B on the inner side.

[0051] The roller 150A is configured to press the inner box rail 240A against the gear 140A2 to prevent derailment.

[0052] Similarly, roller 150B is configured to press inner box rail 240B against gear 140B2 to prevent derailment.

[0053] Next, a configuration example of the inner box 200 according to this embodiment will be described with reference to FIG.

[0054] FIG. 5 shows a top view, a bottom view, a front view, a side view, a rear view, a cross-sectional view taken along the lines AA and BB of the inner box 200.

[0055] The front, sides and back of the inner box 200 are formed from metal sheets (indicated by dots).

[0056] The inner box 200 according to this embodiment includes, on its inner lateral side, an inner box rail 240A that fits with the gears 140A1 and 140A2, and an inner box rail 240B that fits with the gears 140B1 and 140B2.

[0057] Furthermore, inner box 200 according to this embodiment includes magnets 230A and 230B arranged on the bottom surface.

[0058] Magnets 230A and 230B are configured to maintain housing 10 in a fully open state.

[0059] When the housing 10 is in the fully open state, the inner box 200 is located at the bottom end of the movable area. At this time, the magnets 230A and 230B are attracted to the upper surface of the bottom plate of the outer box 100, so that the inner box 200 and the inner box 300 are fixed in place.

[0060] The magnet 230 according to the present embodiment is an example of a fixing part. The fixing part is not limited to the magnet 230, and may be any member that can fix the middle box 200 and the inner box 300 and maintain the housing 10 in the fully open state.

[0061] Next, a configuration example of the inner box 300 according to this embodiment will be described with reference to FIG.

[0062] 6 shows a top view, a bottom view, a front view, a side view, a rear view, a cross-sectional view taken along the line AA, and a cross-sectional view taken along the line BB of the inner box 300. In FIG.

[0063] The upper and lower surfaces of the inner box 300 are formed of metal plates (indicated by dots).

[0064] As described above, the inner box 300 is provided with a handle 310 on its top surface.

[0065] Furthermore, inner box 300 according to this embodiment is provided, on its outer lateral side, with inner box rail 340A that fits with gears 140A1 and 140A2, and inner box rail 340B that fits with gears 140B1 and 140B2.

[0066] The inner box rails 340A and 340B also function as top and bottom connecting members.

[0067] Above, examples of the configurations of outer box 100, middle box 200, and inner box 300 according to this embodiment have been described in detail.

[0068] Next, the operation of gear 140, middle box rail 240, and inner box rail 340 according to this embodiment will be described in detail.

[0069] Fig. 7 is a diagram showing the internal structure of the housing 10 according to this embodiment, and Fig. 8 is an enlarged view of an area D in Fig. 7.

[0070] Gears 140A1 and 140A2 attached to gear mounting bracket 130A provided on outer box 100 are positioned so that they can engage with inner box rail 240A provided on the inner side of inner box 200 and inner box rail 340A provided on the outer side of inner box 300.

[0071] Similarly, gears 140B1 and 140B2 attached to gear mounting bracket 130B provided on outer box 100 are positioned in a position where they can engage with inner box rail 240B provided on the inner side of inner box 200 and inner box rail 340B provided on the outer side of inner box 300.

[0072] Furthermore, rollers 150A provided on the inner side of outer box 100 press inner box rail 240A against gear 140A2, thereby making the fit between inner box rail 240A, gear 140A, and inner box rail 340A stronger.

[0073] Similarly, roller 150B provided on the inside side of outer box 100 presses inner box rail 240B against gear 140B2, thereby making the fit between inner box rail 240B, gear 140B, and inner box rail 340B stronger.

[0074] According to the above configuration, as shown in Fig. 9, upward movement of inner box 300, i.e., upward movement of inner box rail 340A, causes gear 140A2 to rotate counterclockwise. Furthermore, counterclockwise rotation of gear 140A2 pushes inner box rail 240A downward, causing inner box 200 to move downward.

[0075] 10, downward movement of inner box 300, i.e., downward movement of inner box rail 340A, causes gear 140A2 to rotate clockwise. Also, the clockwise rotation of gear 140A2 pushes inner box rail 240A upward, causing inner box 200 to move upward.

[0076] It should be noted that gear 140A1 rotates in the same direction as gear 140A2, and gears 140B1 and 140B2 rotate in the opposite direction to gears 140A1 and 140A2.

[0077] According to the configuration described above, the middle box 200 and the inner box 300 can be linked together.

[0078] <2.Effects> Next, the effects achieved by the housing 10 according to one embodiment of the present invention will be described.

[0079] If the weight of each fire extinguisher 80 is about 9 kg (including about 6 kg of extinguishing agent), the total weight of the inner box 300 in which two fire extinguishers 80 are placed will be considerable, but in the case 10 according to this embodiment, it can be operated by applying a force (=G) equal to or greater than the weight difference (tentative weight difference: 9.8 N=1 kg) between the inner box 300 (in a state in which two fire extinguishers 80 are stored) and the middle box 200. In other words, the case 10 according to this embodiment achieves a reduction in the operating force.

[0080] Furthermore, according to the configuration of the housing 10 according to one embodiment of the present invention, the inner box 300 will not fall freely, so damage to equipment, injury, and the like caused by the inner box 300 falling can be prevented.

[0081] Furthermore, if the adhesive force between the magnets 230A and 230B provided in the inner box 200 and the outer box 100 is set to the above G (e.g., 15 N), the fully open state can be maintained even when two fire extinguishers 80 are stored in the inner box 300, further improving safety.

[0082] Furthermore, according to the configuration of the housing 10 according to one embodiment of the present invention, in the following situations 1 to 3, the fully closed state cannot be maintained and the housing 10 automatically goes to the fully open state, thereby making it possible to avoid human error, etc.

[0083] Situation 1: Fire extinguisher 80 not installed (including cases where the extinguisher was not installed due to forgetting to install it by maintenance personnel, theft, etc.)

[0084] Situation 2: Implementing a fire extinguisher 80 that is 9.8N or more lighter than the prescribed weight

[0085] Situation 3: Fire extinguisher 80 is implemented, which is 9.8N or more lighter than the specified weight due to the injection of fire extinguishing agent.

[0086] Furthermore, according to the configuration of the housing 10 of one embodiment of the present invention, a single operation can be performed to open the door so that it can be accessed from two different locations with steps (the passageway PW side and the roadway RW side), which is expected to improve the efficiency of firefighting activities and maintenance work.

[0087] Furthermore, since the housing 10 according to one embodiment of the present invention does not use wires, there is no need to adjust the length of wires that elongate due to deterioration over time, and maintenance efficiency is improved.

[0088] <3. Conclusion> As described above, the housing 10 according to one embodiment of the present invention includes the outer box 100, the inner box 200 that can be stored inside the outer box 100, and the inner box 300 that can be stored inside the inner box 200 and in which tools used for firefighting activities are placed. The outer box 100 includes a movable part such as a gear 140 that is placed inside the outer box 100. The inner box 200 includes an inner box rail 240 that fits with the movable part on the inner side of the inner box 200. The inner box 300 includes an inner box rail 340 that fits with the movable part on the outer side of the inner box 300. The inner box 200 moves in the opposite direction to the inner box 300 as the inner box 300 moves up and down, and the inner box 300 moves in the opposite direction to the inner box 200 as the inner box 200 moves up and down.

[0089] According to the above-mentioned configuration, it is possible to achieve both easy operation and safety.

[0090] Although the preferred embodiment of the present invention has been described in detail above with reference to the accompanying drawings, the present invention is not limited to such an example. It is clear that a person having ordinary knowledge in the technical field to which the present invention pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.
