Description

Technical Field

[0001] The present disclosure relates to a transmitter, which is a disaster prevention device for notifying abnormalities such as fires.

Background Art

[0002] Among disaster prevention devices that are operated during a fire to conduct fire extinguishing activities, there is a transmitter for manually notifying a fire. As an example, there is a disaster prevention device in which an indicator light and an acoustic hole area are concentrated in one place and arranged in combination with the transmitter (see, for example, Patent Document 1). According to the disaster prevention device of Patent Document 1, by centrally arranging the housed devices, a disaster prevention device that is miniaturized by reducing the installation space and that has improved operability and design has been realized.

[0003] In addition, a transmitter with a ring-shaped indicator light in which the transmitter and the indicator light are integrated is also widely recognized (see, for example, Non-Patent Document 1). According to the transmitter with a ring-shaped indicator light of Non-Patent Document 1, by forming the conventional indicator light into a ring shape and integrating it with the transmitter, a compact form has been realized while maintaining the functions of the transmitter and the indicator light.

[0004] Therefore, by using such a transmitter with a ring-shaped indicator light, a smart disaster prevention device that harmonizes with the space design, is usually inconspicuous and blends into the space design, and becomes conspicuous when needed has been realized.

[0007] However, conventional technologies have the following problems: Transmitters that are mounted on walls, enclosures, etc., are desirable to have a more compact installation space. From this perspective, the disaster prevention device disclosed in Patent Document 1 and the ring-type indicator light transmitter disclosed in Non-Patent Document 1 can contribute to a more compact installation space.

[0008] However, depending on the installation location of the disaster prevention equipment, further space-saving measures may be desirable. For example, when installing disaster prevention equipment on a wall, even if there is ample space in the depth direction behind the wall, it is effective in enhancing product competitiveness to use more compact, space-saving disaster prevention equipment on the surface of the wall.

[0009] This disclosure is made to solve the above-mentioned problems and aims to provide a transmitter that can realize disaster prevention equipment that is more space-saving than existing products. [Means for solving the problem]

[0010] The transmitter relating to this disclosure is a transmitter that has the function of signaling a fire by manual operation, and has a configuration in which an indicator light that shows the location of the transmitter and an audible device that outputs a fire alarm are mounted on a printed circuit board and housed in the transmitter's casing, with the indicator light and the audible device being mounted on the front and back sides of the printed circuit board. [Effects of the Invention]

[0011] According to this disclosure, it is possible to obtain a transmitter that can realize disaster prevention equipment that is more space-saving than existing products. [Brief explanation of the drawing]

[0012] [Figure 1] This is an explanatory diagram relating to an all-in-one type transmitter according to Embodiment 1 of the present disclosure. [Figure 2] This is an explanatory diagram showing a comparison of the shape in the depth direction between the all-in-one type transmitter according to Embodiment 1 of the present disclosure and an existing transmitter with a ring-type indicator light. [Figure 3] This is a front view showing the all-in-one type transmitter according to Embodiment 1 of the present disclosure housed in an equipment housing box. [Figure 4] This is an explanatory diagram relating to an all-in-one type transmitter according to Embodiment 2 of the present disclosure. [Figure 5] This is an explanatory diagram showing two specific implementation methods for an all-in-one type transmitter according to Embodiment 2 of this disclosure. [Figure 6] This is an explanatory diagram of the conventional technology in which a ring-shaped indicator light transmitter and an acoustic device are housed in an equipment storage box. [Modes for carrying out the invention]

[0013] Hereinafter, preferred embodiments of this disclosure will be described with reference to the drawings. The transmitter described herein has a technical feature in that, in addition to the original function of a manual fire alarm transmitter, it adds a display function and an audible function, and is an all-in-one type transmitter in which the transmitter, indicator light, and audible device are all integrated, making it a product suitable for space saving.

[0014] Embodiment 1. First, we will describe conventional devices in which the transmitter, indicator light, and sound device are not integrated into a single unit. Then, we will describe the all-in-one transmitter disclosed in this disclosure, which is suitable for saving space.

[0015] FIG. 6 is an explanatory diagram of the prior art in a state where a transmitter with a ring-shaped display lamp and an acoustic device are housed in an equipment storage box. As the transmitter with a ring-shaped display lamp, the one disclosed in Non-Patent Document 1 can be applied. In the equipment storage box 1 shown in FIG. 6, by using a transmitter with a ring-shaped display lamp in which the transmitter 10 and the display lamp 20 are integrated, space saving is achieved. However, separately from the transmitter with a ring-shaped display lamp, it is necessary to arrange the acoustic device 30.

[0016] On the other hand, the transmitter according to Embodiment 1 has an all-in-one configuration in which the functions of the transmitter, the display lamp, and the acoustic device are all integrated and housed in one transmitter housing, making it suitable for space saving. Therefore, the transmitter according to Embodiment 1 will be described using FIGS. 1 and 2.

[0017] FIG. 1 is an explanatory diagram of an all-in-one type transmitter according to Embodiment 1 of the present disclosure. The transmitter 100 according to Embodiment 1 is configured by integrating a transmitter 10 mainly for notifying a fire by manual operation, a display lamp 20 mainly for visually recognizing the position of the transmitter, and an acoustic device 30 mainly for outputting a fire alarm.

[0018] In other words, in the all-in-one type transmitter 100, the display lamp 20 and the acoustic device 30 are housed in the housing of the transmitter 10, and the transmitter 10, the display lamp 20, and the acoustic device 30 are integrated. Therefore, there is no need to separately arrange the acoustic device 30 as shown in FIG. 6 above, and space saving can be achieved.

[0019] As the acoustic device 30, any one of a bell, an electronic buzzer, and a speaker can be applied. Further, by forming acoustic holes as shown in FIG. 1 on the front surface of the transmitter 10, the sound emitted from the acoustic device 30 can be efficiently output.

[0020] Figure 2 is an explanatory diagram showing a comparison of the shapes in the depth direction of an all-in-one type transmitter 100 according to Embodiment 1 of this disclosure and an existing ring-type indicator light transmitter 200. In Figure 2(A), the depth dimension of the all-in-one type transmitter 100 according to Embodiment 1 is shown as LA. Specifically, the sum of the thicknesses of the main body 101, which is attached to a wall, storage box, etc., and the storage section 102 on the rear side of the main body 101, where components, wiring, etc. are stored, is shown as the depth dimension LA.

[0021] On the other hand, in Figure 2(B), the depth dimension of the existing ring-type indicator light transmitter 200 is shown as LB. Specifically, the sum of the thickness of the main body 201, which is mounted on a wall, housing, etc., and the storage section 202 on the rear side of the main body 201, which houses components, wiring, etc., is shown as the depth dimension LB.

[0022] The acoustic device 30 is housed in the storage compartment 102 of the all-in-one transmitter 100. Therefore, the depth dimension LA is longer than the depth dimension LB. However, the surface area of ​​the main body 101 of the all-in-one transmitter 100 is the same as the surface area of ​​the main body 201 of the existing ring-type indicator light transmitter 200.

[0023] Figure 3 is a front view showing the all-in-one type transmitter 100 according to Embodiment 1 of this disclosure housed in an equipment housing box. Compared to the layout in Figure 6, as shown in Figure 3, adopting the all-in-one type transmitter 100 allows for space savings in the equipment housing box.

[0024] Although the wiring for the all-in-one transmitter 100 is not shown in the diagram, it requires 4 wires for the transmitter, 2 for the indicator lights, and 2 for the sound device, and can be wired using the same number of wires as the conventional configuration shown in Figure 6.

[0025] As described above, Embodiment 1 adds display and sound functions to the original function of a manual fire alarm transmitter, and realizes an all-in-one configuration in which the transmitter, indicator light, and sound device are all integrated and housed in a single transmitter housing. As a result, it is possible to obtain a transmitter that can realize fire prevention equipment that is more space-saving than current products.

[0026] Embodiment 2. In the first embodiment described above, a configuration was adopted in which an acoustic device 30 is added to an existing ring-type indicator light transmitter. In contrast, this second embodiment describes a configuration in which an existing ring-type indicator light transmitter is not used.

[0027] Figure 4 is an explanatory diagram relating to an all-in-one type transmitter according to Embodiment 2 of the present disclosure. The transmitter 100a according to Embodiment 2 is configured by integrating a transmitter 10a whose main purpose is to signal a fire by manual operation, an indicator light 20a whose main purpose is to make the location of the transmitter visible, and an audible device 30a whose main purpose is to output a fire alarm.

[0028] In other words, the all-in-one transmitter 100a has the indicator light 20a and the sound device 30a housed within the casing of the transmitter 10a, and the transmitter 10a, indicator light 20a, and sound device 30a are integrated into a single unit. Therefore, as shown in Figure 6 above, there is no need to separately arrange the sound device 30, and space saving can be achieved.

[0029] The sound device 30a can be a bell, an electronic buzzer, or a speaker. In addition, by forming multiple acoustic slits on the front of the transmitter 10a as shown in Figure 4, the sound emitted from the sound device 30a can be output efficiently.

[0030] Figure 5 is an explanatory diagram showing two specific mounting methods for the all-in-one type transmitter 100a according to Embodiment 2 of this disclosure. In Figure 5(A), the transmitter 10a, indicator light 20a, and sound device 30a are mounted on the front side of the printed circuit board PC. On the other hand, in Figure 5(B), the transmitter 10a and indicator light 20a are mounted on the front side of the printed circuit board PC, and the sound device 30a is mounted on the back side.

[0031] By adopting a layout like that shown in Figure 5(A) or Figure 5(B), it is possible to realize an all-in-one configuration in which the transmitter, indicator light, and sound device are all integrated and housed within a single transmitter housing, without using existing ring-type indicator light transmitters.

[0032] When the all-in-one type transmitter 100a according to this second embodiment is adopted, the depth dimension will be longer than that of the existing ring-type indicator light transmitter 200, similar to when the all-in-one type transmitter 100a according to the first embodiment is adopted. However, the area exposed on the surface side will be the same as that of the existing ring-type indicator light transmitter 200, and space can be saved compared to the layout in Figure 6.

[0033] In Figure 4, the small circular shape in the center represents the push button of the transmitter 10a. By forming multiple acoustic slits or holes on the front surface of the transmitter 10a, including the push button, as shown in Figure 4, the sound emitted from the acoustic device 30a can be output efficiently.

[0034] Furthermore, with respect to Figure 5(A) or Figure 5(B), by appropriately and as needed, forming multiple acoustic slits or holes in the components housed on the front side of the acoustic device 30a within the housing of the transmitter 10a, the sound emitted from the acoustic device 30a can be output efficiently.

[0035] As described above, according to Embodiment 2, in addition to the original function of a manual fire alarm transmitter, a display function and an audible function are added, and an all-in-one configuration is achieved in which the transmitter, indicator light, and audible device are all integrated and housed in a single transmitter housing. As a result, it is possible to obtain a transmitter that can realize fire prevention equipment that is more space-saving than current products. [Explanation of Symbols]
