Description

[Technical field]

[0001] The present invention relates to a disaster prevention device. [Background technology]

[0002] In recent years, fire prevention equipment to protect people and vehicles from fires has become widespread. Many methods have also been proposed to improve the safety and convenience of fire prevention equipment. For example, fire hydrant devices that house fire hydrants are installed in road tunnels.

[0003] Disaster prevention equipment such as fire hydrants is provided with a push button type transmitter, as disclosed in Patent Document 1, for example. When an operator presses the push button on the transmitter, the transmitter reports the occurrence of a fire. A protective plate that protects the push button is attached to the transmitter, and the operator can press the push button by strongly pressing the protective plate to destroy it.

[0004] On the other hand, when checking the operation of the push button, it is desirable that the protective plate is not destroyed. In this regard, in one fire hydrant device, the protective plate is fixed from the front side by a resin ring having a notch, and the operator removes the ring by hooking the nail of the finger into the notch, and then removes the protective plate forward and presses the push button. In addition, in the fire hydrant device disclosed in Patent Document 1, a hole is provided in the front side of the protective plate, and the operator inserts a special tool into the hole to press the push button.

[0005] [Patent Document 1] JP 2018-81341 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in a fire hydrant device in which the protective plate is fixed by a ring having a notch, the resin of the ring may be damaged when the operator removes the ring. In addition, since the operator cannot hook his / her fingernails into the notch when wearing gloves, the operator is required to work with bare hands. In addition, the fire hydrant device disclosed in Patent Document 2 requires a dedicated tool to remove the protective plate. In addition, in order to replace the protective plate in the fire hydrant device disclosed in Patent Document 2, the entire plate needs to be removed with a tool.

[0007] Therefore, the present invention has been made in consideration of the above problems, and an object of the present invention is to provide a new and improved disaster prevention device that allows the protective plate to be easily removed without the use of tools.

[0015] Hereinafter, an embodiment 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 denoted by the same reference numerals, and duplicated explanations will be omitted.

[0016] In addition, in this specification and drawings, multiple components having substantially the same functional configuration may be distinguished by adding different alphabets after the same reference numeral. However, when there is no need to particularly distinguish between multiple components having substantially the same functional configuration, each of the multiple components is given only the same reference numeral.

[0017] <Fire hydrant equipment overview> An embodiment of the present invention relates to a disaster prevention device. Examples of the disaster prevention device include a fire extinguisher storage device, a fire hydrant device, and an emergency alarm device. In this specification, an example in which an embodiment of the present invention is applied to a fire hydrant device will be mainly described as an example of a disaster prevention device. For example, the fire hydrant device is arranged in a road tunnel for disaster prevention and firefighting purposes in the road tunnel. In addition to the roadway on which vehicles run, a passageway is provided beside the roadway for use in maintenance work by monitors and as an evacuation route in the event of a disaster. The passageway is generally provided at a position about 900 to 1000 mm higher than the roadway.

[0018] Hereinafter, an overview of a fire hydrant device according to one embodiment of the present invention will be described with reference to Figs. 1 and 2.

[0019] Fig. 1 is an explanatory diagram showing an example of the arrangement of a fire hydrant device 10 according to one embodiment of the present invention. As shown in Fig. 1, the fire hydrant device 10 according to one embodiment of the present invention is located at the boundary between a roadway and a passageway. As shown in Fig. 1, the fire hydrant device 10 includes a housing body having a roadway side surface 12 located on the roadway side, a passageway side surface 14 facing the passageway side, a pair of opposing side surfaces (an upstream side surface located on the upstream side of the roadway and a downstream side surface 16 located on the downstream side) located between the roadway side surface 12 and the passageway side surface 14, and a top surface 19.

[0020] Doors for opening and closing the storage space for the fire hydrant are provided on the roadway side 12 and the passage side 14. Therefore, an operator can use the fire hydrant from the roadway by opening the door on the roadway side 12, and can use the fire hydrant from the passage by opening the door on the passage side 14.

[0021] Fig. 2 is a front view of the roadway side 12 of the fire hydrant device 10. As shown in Fig. 2, the roadway side 12 of the fire hydrant device 10 according to one embodiment of the present invention has a roadway side door 122, which is a door for opening and closing the storage space for the fire hydrant, and a fire detector 124. The roadway side door 122 opens and closes the storage space for the fire hydrant by, for example, sliding movement. The fire detector 124 detects the occurrence of a fire.

[0022] In addition, a guide section 125 consisting of an SOS nameplate 126 and an arrow mark 127 is formed on the roadway side surface 12 of the fire hydrant device 10. The arrow mark 127 points in the direction of the downstream side surface 16 on which a push button alarm 162 (described later) is provided.

[0023] Next, the configuration of the downstream side surface 16 of the fire hydrant device 10 will be described with reference to Fig. 1. As shown in Fig. 1, a push button alarm 162, which is an example of a transmitter, a response lamp 164, and an SOS nameplate 166 are formed on the downstream side surface 16 of the fire hydrant device 10.

[0024] The push button alarm 162 has a push button that the operator presses when a fire or the like occurs, and transmits a notification signal indicating the occurrence of a fire to the disaster prevention receiving panel when the push button is pressed. The response lamp 164 lights up when the disaster prevention receiving panel receives a notification signal. The SOS nameplate 166 is a display that guides the operator to press the push button alarm 162.

[0025] One embodiment of the present invention relates to the configuration of the above-mentioned fire hydrant device 10, particularly to the peripheral configuration of the push button alarm 162. Hereinafter, the peripheral configuration of the push button alarm 162 will be described in more detail.

[0026] <Push button alarm 162 peripheral configuration> Fig. 3 is a front view of the push button alarm 162 and the peripheral configuration of the push button alarm 162. As shown in Fig. 3, the push button alarm 162 has a push button 163. A mounting part 200 is mounted on the downstream side surface 16 of the fire hydrant device 10, and a protective plate 260 that protects the push button 163 is located between the mounting part 200 and the push button 163.

[0027] The protective plate 260 is translucent, and as shown in Fig. 3, for example, the word "press hard" is formed on the protective plate 260. In addition, a plurality of arc-shaped openings 262 are intermittently formed on the protective plate 260. Therefore, the portion connecting the plurality of openings 262 becomes a weak portion, and when the protective plate 260 is pressed hard, the weak portion is broken, and it becomes possible to press the push button 163. The openings 262 and the weak portion are usually provided at a position overlapping with the mounting part 200, and therefore cannot be seen from the outside of the fire hydrant device 10.

[0028] (Housing side configuration) Fig. 4 is an explanatory diagram showing the configuration on the housing side. Specifically, Fig. 4 shows a front view of the configuration on the housing side around the push button alarm 162, and a cross-sectional view along line II-II in the plan view. As shown in Fig. 4, the housing side is provided with a push button side tube portion 167, which is a tubular configuration surrounding the push button 163. A push button side screwing portion 167a is formed on the outer circumferential surface of the push button side tube portion 167 to screw with the mounting portion side tube portion 210 described later.

[0029] Further, a circular opening 168 is formed in the downstream side surface 16 of the fire hydrant device 10. In the front view shown in Fig. 4, the push button side cylinder portion 167 and the push button 163 are located inside the circular opening 168. Further, a protrusion insertion opening 169 connected to the circular opening 168 is formed in the downstream side surface 16 of the fire hydrant device 10. A protrusion 219 on the mounting part 200 side, which will be described later, is inserted into the protrusion insertion opening 169.

[0030] (Configuration of mounting part) Fig. 5 is a cross-sectional view of the mounting part 200 taken along line II in Fig. 3. As shown in Fig. 5, the mounting part 200 has a mounting part side tube part 210, an annular part 220, a protruding part 230, and a rubber ring 240. The mounting part side tube part 210 has a cylindrical configuration. On the inner peripheral surface of the mounting part side tube part 210, a mounting part side screw part 210a that screws into the push button side screw part 167a of the push button side tube part 167 is formed. In addition, a protrusion 219 that protrudes from the outer peripheral side is formed on the end part of the mounting part side tube part 210.

[0031] The annular portion 220 has an annular configuration. The mounting portion side cylinder portion 210 extends from one side surface of the annular portion 220. The inner diameter of the annular portion 220 is smaller than the inner diameter of the mounting portion side cylinder portion 210, and the outer shape of the annular portion 220 is larger than the outer diameter of the mounting portion side cylinder portion 210.

[0032] The protruding portion 230 protrudes from the annular portion 220 to the opposite side of the mounting portion side cylindrical portion 210. In the example shown in Fig. 5, the protruding portion 230 has a cylindrical configuration formed continuously in the circumferential direction, but the protruding portion 230 may be formed in a portion in the circumferential direction.

[0033] The rubber ring 240 is an elastic member that is adjacent to the annular portion 220 and surrounds the outside of the mounting portion side cylinder portion 210 .

[0034] The outer edge of protective plate 260 is covered by annular portion 220, and the center of protective plate 260 is exposed through the hollow portion of annular portion 220. The outer diameter of protective plate 260 is smaller than the diameter of mounting portion side screw portion 210a of mounting portion side cylinder portion 210. Therefore, a gap exists between protective plate 260 and mounting portion side screw portion 210a.

[0035] <Attachment / detachment of the mounting part 200> Next, a state in which the mounting unit 200 is mounted on the housing, and attachment and detachment of the mounting unit 200 will be described.

[0036] Fig. 6 is an explanatory diagram showing a state in which the mounting part 200 is mounted on the housing. As shown in Fig. 6, the mounting part 200 is mounted on the housing by screwing the mounting part side cylinder part 210 into the push button side cylinder part 167. The mounted state shown in Fig. 6 is a state in which the screwing between the mounting part side cylinder part 210 and the push button side cylinder part 167 does not proceed any further. In this mounted state, the protective plate 260 is positioned between the push button side cylinder part 167 and the annular part 220, and protects the push button 163.

[0037] FIG. 7 is an enlarged view of the X region shown in FIG. 6. As shown in FIG. 7, in the mounted state of the mounting portion 200, the rubber ring 240 is sandwiched between the housing and the annular portion 220. Also, the distance between the push button side cylinder portion 167 and the annular portion 220 is greater than the thickness of the protective plate 260. Therefore, a gap is provided between the protective plate 260 and the annular portion 220, or between the protective plate 260 and the push button side cylinder portion 167. The amount of the gap depends on, for example, the thickness of the rubber ring 240 and the relationship between the position of the outer surface of the housing and the height of the push button side cylinder portion 167. In the examples shown in FIG. 6 and FIG. 7, the height of the push button side cylinder portion 167 is designed to be such that it does not reach the position of the outer surface of the housing.

[0038] With mounting part 200 attached in this manner, the operator can release the screw engagement between mounting part side cylinder part 210 and push button side cylinder part 167 by rotating mounting part 200 in the A1 direction shown in Fig. 3 while holding convex part 230. Then, as shown in Fig. 8, the operator can adjust the rotational position of mounting part 200 so that protrusion 219 fits into protrusion insertion opening 169, and pull mounting part 200 with protrusion 219 fitting into protrusion insertion opening 169, thereby removing mounting part 200.

[0039] Conversely, when mounting the mounting part 200 to the housing, the operator adjusts the rotational position of the mounting part 200 so that the protrusion 219 fits into the protrusion insertion opening 169, and pushes the mounting part 200 into the circular opening 168 with the protrusion 219 fitting into the protrusion insertion opening 169. Then, the operator rotates the mounting part 200 in the A2 direction shown in Fig. 3 while holding the convex part 230, thereby screwing the mounting part side cylinder part 210 and the push button side cylinder part 167 together. When this screwing is completed, the mounting part 200 is mounted to the housing.

[0040] <Action and effect> According to the embodiment of the present invention described above, various operational effects can be obtained. For example, in the fire hydrant device 10 according to the embodiment of the present invention, the operator can easily attach and detach the mounting part 200 by rotating the mounting part 200 while holding the protruding part 230. The operator can perform this operation without removing protective gloves and without using a dedicated tool. Therefore, it is easy to check the operation of the push button 163 and replace the protective plate 260.

[0041] Furthermore, according to one embodiment of the present invention, a protrusion 219 is provided on the mounting part 200 side, and a protrusion insertion opening 169 is formed on the housing side. Since the mounting part 200 can be attached and detached only when the position of the protrusion 219 matches the protrusion insertion opening 169, it is possible to prevent the mounting part 200 from being unintentionally removed.

[0042] Furthermore, according to one embodiment of the present invention, the outer diameter of protective plate 260 is smaller than the diameter of mounting part side screw part 210a of mounting part side cylinder part 210, and a gap exists between protective plate 260 and mounting part side screw part 210a. Therefore, protective plate 260 can be easily removed from mounting part 200 and attached into mounting part 200.

[0043] Furthermore, according to one embodiment of the present invention, when the mounting portion 200 is mounted, the rubber ring 240 is sandwiched between the housing and the annular portion 220. This makes it possible to prevent loosening of the screw engagement between the mounting portion side cylinder portion 210 and the push button side cylinder portion 167, and to prevent water leakage from the outside.

[0044] Furthermore, according to one embodiment of the present invention, when mounting portion 200 is mounted, a gap is provided between protective plate 260 and annular portion 220, or between protective plate 260 and push button side cylinder portion 167. This makes it possible to prevent damage or cracking of protective plate 260 due to tightening of protective plate 260. Furthermore, since protective plate 260 can be rotated even in the mounted state, it is possible to easily adjust the inclination of characters such as "press hard."

[0045] <Supplementary Information> 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.
