[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments, and various modifications are possible without departing from the spirit of the present invention. Furthermore, the present invention includes all possible combinations of the configurations shown in the following embodiments. Furthermore, the device shown in the drawings is an example of the device of the present invention, and the device of the present invention is not limited to the device shown in the drawings. Furthermore, in each drawing, parts with the same reference numerals are the same or equivalent, and this is common throughout the entire specification.

[0011] Embodiment 1 FIG. 1 is a schematic diagram showing an example of disaster prevention equipment according to a first embodiment. The disaster prevention device exemplified in this embodiment is a fire hydrant starter 1. The fire hydrant starter 1 is a device that starts the pump of a fire hydrant (not shown). The fire hydrant starter 1 of this embodiment includes a case 2, a cover 3, an operation unit 4, a protective plate 5, a magnet 6, a fixing plate 7, a finger hook 8, and a lamp 9.

[0012] The case 2 is a housing with an opening 2a on the front, and houses the operation unit 4 and lamp 9. The case 2 also houses components such as a control circuit that controls the operation unit 4 and lamp 9, and a signal line that connects to the hydrant pump. The case 2 is made of synthetic resin or metal.

[0013] The cover 3 detachably covers the opening 2a on the front surface of the case 2. The cover 3 has an opening 3a formed therein, and a protective plate 5 is disposed within the opening 3a. The cover 3 is made of synthetic resin or metal.

[0014] In this embodiment, the operating unit 4 is a push button. When the operating unit 4 is pressed, the pump of the fire hydrant, which is disaster prevention equipment, starts up and operates. The operating unit 4 is not limited to a push button, and may be, for example, an operating lever that operates the disaster prevention equipment when pressed or pulled.

[0015] The protective plate 5 is attached to the cover 3 and is positioned opposite the operation unit 4 when the cover 3 is attached to the case 2. The protective plate 5 faces the operation unit 4 to protect it. The protective plate 5 is pushed away from the front of the cover 3, exposing the operation unit 4 and enabling the user to operate it. In this embodiment, the protective plate 5 is circular and made of transparent synthetic resin such as acrylic or organic glass, and is disposed in the opening 3a provided in the cover 3. Multiple fragile portions 5a are provided at the outer periphery of the protective plate 5, connecting the protective plate 5 to the edge of the opening 3a of the cover 3. The fragile portions 5a are configured to withstand a static load of, for example, 20 N but to break when a static load of 80 N is applied. When the protective plate 5 is pressed, the fragile portions 5a break, causing the protective plate 5 to detach from the cover 3, exposing the operation unit 4 through the opening 3a. The protective plate 5 may also be sandwiched between the cover 3 and the case 2.

[0016] 1 illustrates an embodiment in which four fragile portions 5a are provided on the outer periphery of the protective plate 5, but the number of fragile portions 5a is not limited to four. Furthermore, although the present embodiment illustrates the protective plate 5 configured to be pushed out, the protective plate 5 may also be configured to be broken by pushing. In this case, for example, the protective plate 5 may be made more fragile by providing a crease therein so as to be easily broken, and fitted into the opening 3a.

[0017] The magnet 6 secures the case 2 and the cover 3 together. The magnet 6 is, for example, in the form of a sheet, and is adhered to the inner surface of the cover 3 with adhesive tape or the like. In the example of FIG. 1, the magnets 6 are provided at the top and bottom of the front surface of the cover 3. The case 2 is provided with fixing plates 7 at positions facing the magnets 6. The fixing plates 7 are plates made of a ferromagnetic material such as iron. The fixing plates 7 are provided at the top and bottom of the edge of the opening surface 2a of the case 2, respectively, so as to cover part of the opening surface 2a. When the cover 3 is placed over the case 2, the magnet 6 adheres to the fixing plates 7, and the case 2 and the cover 3 are secured together.

[0018] The number, shape, and arrangement of the magnets 6 are not limited to those shown in the drawings. For example, circular or rectangular magnets 6 may be attached to the four corners of the surface of the cover 3 where the opening 3a is provided. In this case, fixing plates 7 to which the magnets 6 are attached are disposed at the four corners of the opening surface 2a of the case 2. The magnets 6 may also be provided on the inner surface of the peripheral wall of the cover 3. In this case, the cover 3 is externally fitted to the outside of the case 2, and the case 2 is made of a ferromagnetic material such as iron, so that the magnets 6 adhere to the case 2 and fix the case 2 and cover 3, eliminating the need for the fixing plate 7. The magnets 6 may also be provided on the outer surface of the peripheral wall of the cover 3. In this case, the cover 3 is internally fitted to the inside of the case 2, and the case 2 is made of a ferromagnetic material such as iron, so that the magnets 6 adhere to the case 2 and fix the case 2 and cover 3, eliminating the need for the fixing plate 7. The magnets 6 may also be provided on the case 2 instead of the cover 3. In this case, by providing magnets 6 on the inner or outer surface of the peripheral wall of case 2 and making cover 3 out of a ferromagnetic material such as iron, case 2 and cover 3 can be fixed together without fixing plate 7.

[0019] The finger hook 8 is a portion on which a user places their finger when removing the cover 3. In FIG. 1, the finger hook 8 is a protrusion protruding from the outer surface of the cover 3. In addition, in the present embodiment, an example is shown in which the finger hook 8 is provided on the upper peripheral wall of the cover 3. However, the finger hook 8 may be provided on the left, right, or lower peripheral wall of the cover 3, or on the front panel of the cover 3. The shape of the finger hook 8 is not limited to the plate shape shown in the figure, and may be any shape that allows a finger to be placed on it. The finger hook 8 may be a hole or recess formed on any part of the cover 3. In this case, the user places their finger on the edge of the hole or recess. By placing their finger on the finger hook 8 and pulling it toward themselves, the user can easily remove the cover 3 from the case 2.

[0020] The lamp 9 is an alarm unit that issues an alarm when the cover 3 is removed from the case 2. The lamp 9 is, for example, a light-emitting element such as an LED. The lamp 9 lights up when the cover 3 is detected to be removed based on the detection result of a cover detection unit that detects whether the cover 3 is attached to the case 2. This makes it easier for a user to recognize that the cover 3 has been removed, thereby preventing the cover 3 from being overlooked or installed improperly. Here, the cover detection unit may be, for example, a limit switch that outputs a signal when the cover 3 is properly attached. Alternatively, a timer may be provided to measure the elapsed time after the cover 3 has been removed, and the lamp 9 may light up when the cover 3 remains removed for a predetermined period of time. The lamp 9 may also be attached to the outer surface of the case 2. The lamp 9 may have a function of lighting up when the operating unit 4 is pressed while the cover 3 is attached and is off. The lamp 9 may also have a function of lighting up or flashing when the operating unit 4 is pressed, thereby activating the disaster prevention equipment, the fire hydrant device, or the like.

[0021] Instead of or in addition to the lamp 9, the fire hydrant starter 1 may be provided with a buzzer or speaker that outputs sound as an alarm unit. The alarm unit may also be provided outside the fire hydrant starter 1. For example, the alarm unit may be a control panel that is communicatively connected to the fire hydrant starter 1, etc., and when the cover 3 is removed, the fire hydrant starter 1 may send a signal to the control panel, which may then issue a visual or audio alarm.

[0022] As described above, the fire hydrant starter 1 of this embodiment comprises an operating unit 4 that operates the hydrant pump, a protective plate 5 positioned opposite the operating unit 4, a case 2 that houses the operating unit 4, a cover 3 that has the protective plate 5 and covers the case 2, and a magnet 6 that secures the cover 3 to the case 2.

[0023] Because the case 2 and the cover 3 are fixed by the magnet 6, removing the cover 3 allows inspection of the components inside the case 2 without destroying the protective plate 5. Furthermore, for example, if the cover 3 and the case 2 are fixed with screws, removing the cover 3 requires removing the screws, which requires tools and is time-consuming. However, in this embodiment, the cover 3 can be removed from the case 2 without using tools. Therefore, according to this embodiment, the number of steps required to remove and attach the cover 3 can be reduced compared to when the cover 3 is fixed with screws.

[0024] Furthermore, in this embodiment, the cover 3 is provided with a finger hook 8 on which a finger can be hooked, thereby improving the workability when removing the cover 3.

[0025] Furthermore, in this embodiment, a lamp 9 is provided as a notification unit that notifies when the cover 3 is removed from the case 2. Therefore, if the cover 3 is not attached properly or is not properly attached after inspection, this can be notified to the user.

[0026] Embodiment 2 In this embodiment, a fire hydrant device 10 including a fire hydrant starter 1 according to embodiment 1 will be described. In this embodiment, differences from embodiment 1 will be mainly described.

[0027] FIG. 2 is a schematic diagram showing an example of a fire hydrant apparatus 10 according to a second embodiment. The fire hydrant apparatus 10 is a water discharge facility used mainly for initial fire extinguishing. The fire hydrant apparatus 10 includes a fire hydrant box 11, a door 12, and a water discharge hose 13 and a fire extinguisher 14 housed in the fire hydrant box 11. The interior of the fire hydrant box 11 is divided into left and right compartments, and the fire hydrant starter 1 described in the first embodiment is housed in the same compartment as the fire extinguisher 14. The door 12 is a door that pivots left and right, for example, with its left side pivoted. When the door 12 is opened, the fire hydrant starter 1 is exposed as shown in FIG. 2. When the door 12 is closed, the fire hydrant starter 1 is not visible from the outside.

[0028] The fire hydrant device 10 of this embodiment further includes a transmitter 20. The transmitter 20 is arranged outside the space in which the hose 13 of the hydrant box 11 is housed so as to be exposed to the outside. The transmitter 20 is a device that allows a person who discovers a fire to manually send a fire signal. The transmitter 20 includes a push button, and when the push button is pressed, a fire signal is sent to a fire alarm system such as a control panel (not shown). In front of the push button of the transmitter 20, a protective plate is provided that has a structure that can be pushed torn or pushed off, similar to the protective plate 5.

[0029] In this embodiment, the hydrant starter 1 is housed in a hydrant box 11 having a door 12. Therefore, when the hydrant device 10 is not in use, the hydrant starter 1 is covered by the door 12. Therefore, even if the cover 3 is attached to the case 2 (see FIG. 1) with a magnet 6 and can be removed without tools, the cover 3 is protected by the door 12 and is difficult to remove by tampering or the like.

[0030] Although the first and second embodiments show an example in which the disaster prevention device of the present invention is the fire hydrant starter 1, the disaster prevention device of the present invention may also be a transmitter 20. By attaching a cover with a protective plate for the transmitter 20 to a case that houses a push button, which is the operating section of the transmitter 20, with a magnet, it is possible to inspect the components inside the case without destroying the protective plate during inspection, etc. Furthermore, the configuration of the present invention is not limited to the transmitter 20 integrated with the fire hydrant device 10 shown in FIG. 2, but may also be applied to a transmitter that is installed independently.

[0031] Furthermore, in the first and second embodiments, the magnet 6 on the cover 3 and the metal fixing plate 7 on the case 2 are described as connecting the two. However, an electromagnet may be used as the magnet 6. In this case, the fire hydrant starter, which is a disaster prevention device, is connected to a disaster prevention panel (not shown) installed in a management center via a signal line, and the electromagnet can be turned on and off by a signal based on an operation on the disaster prevention panel. When inspecting the fire hydrant starter, the electromagnet can be turned off from the disaster prevention panel beforehand, allowing the cover of the fire hydrant starter to be easily removed. Furthermore, when an electromagnet is used as the magnet 6, the case 2 and the cover 3 may be easily locked together using a locking structure such as a hook. This locking structure is simply used to prevent the cover 3 from falling due to the loss of magnetic force from the case 2 when the electromagnet is turned off; a strong locking force is not required.
