Technical Field

[0001] This invention relates to a disaster prevention device. Background Technology

[0002] In related technologies, detectors installed, such as on a ceiling, to detect heat caused by a fire are known (e.g., see Patent Document 1). In such detectors, tests are performed periodically, but the detectors are configured to output information about the tests by emitting light from indicator lights located on the detector housing.

[0004] Patent documents

[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-198757 Summary of the Invention

[0006] Technical issues

[0007] However, since the detector test in Patent Document 1 is performed by heating the detector, for example, by using a test fixture that is cylindrical in shape and covers at least part of the detector, when the detector is heated while at least part of the detector is covered by the test fixture, the indicator light of the detector may be blocked by the test fixture and cannot be seen, and the user cannot identify information about the test when it is heated.

[0008] Therefore, there is still room for improvement in the ability to identify test-related information even when at least part of the detector is covered by the test fixture.

[0009] The present invention was conceived in view of the above-mentioned problems, and its object is to provide a disaster prevention device that can identify information about the test even when at least a portion of the disaster prevention device is covered by the test device.

[0010] Solution to the problem

[0011] To solve the above problems and achieve the above objectives, the disaster prevention device of claim 1 includes: a housing; and an indicator that outputs at least information about the test of the disaster prevention device by emitting light, and is disposed in the housing, wherein when at least a portion of the housing is covered by a test device for testing the disaster prevention device, at least a portion of the indicator surface of the indicator is exposed to the outside of the test device.

[0012] The disaster prevention device of claim 2 is the disaster prevention device according to claim 1, wherein the indicator protrudes from the side of the housing.

[0013] The disaster prevention device of claim 3 is the disaster prevention device according to claim 1 or 2, wherein the indicator is formed in at least one side of the housing.

[0014] The disaster prevention device of claim 4 is the disaster prevention device according to any one of claims 1 to 3, wherein the indicator is formed in at least one edge of the front portion of the housing.

[0015] The disaster prevention device of claim 5 is the disaster prevention device according to any one of claims 1 to 4, wherein the indicator is a light guide formed in the housing and guides light from the light emitter.

[0016] The disaster prevention device of claim 6 is the disaster prevention device according to any one of claims 1 to 5, wherein the indicator is a thin-walled portion that is thinner than the other portions of the housing and is illuminated by light from a light emitter.

[0017] The disaster prevention device of claim 7 is the disaster prevention device according to any one of claims 1 to 6, wherein the disaster prevention device is at least a thermal detector.

[0018] Beneficial effects of the present invention

[0019] According to claim 1, when the housing of the disaster prevention device is covered by the test equipment for testing the disaster prevention device, at least a portion of the indicator surface of the indicator is exposed to the outside of the test equipment. Therefore, even when at least a portion of the disaster prevention device is covered by the test equipment, a portion of the indicator can be seen, thereby enabling the identification of information related to the test.

[0020] The disaster prevention device according to claim 2, for example, is clearly visible because the indicator protrudes from the side of the housing, thus ensuring the accurate identification of information about the test.

[0021] According to claim 3, since the indicator is formed on the side of the housing, the indicator is visible from any direction relative to the disaster prevention device, thus information about the test can be reliably identified.

[0022] According to claim 4, since the indicator is formed on the edge of the front part of the housing, for example, the indicator can be seen even from directly below the disaster prevention device, thus ensuring the identification of information about the test.

[0023] According to claim 5, since the indicator is part of the light guide, the freedom of the installation position of the indicator's light source (e.g., light emitter) can be increased, thus improving the design freedom of the disaster prevention equipment.

[0024] According to claim 6, since the indicator is part of a thin-walled section, for example, no additional components for emitting light are required, thus reducing the number of components and lowering costs.

[0025] According to claim 7, since the disaster prevention device is at least a thermal detector, it is able to provide information about the test, for example, even when at least a portion of the disaster prevention device is covered by the test device. Attached Figure Description

[0077] Hereinafter, specific embodiments of the disaster prevention device of the present invention will be described in detail with reference to the accompanying drawings. Incidentally, the present invention is not limited to these specific embodiments.

[0078] [Basic Concepts of Specific Embodiments]

[0079] First, the basic concepts of specific embodiments will be described. These specific embodiments are generally about disaster prevention equipment.

[0080] "Disaster prevention equipment" refers to equipment used to prevent disasters. It includes devices that detect anomalies in monitored areas, such as heat detectors, fire detectors, gas detectors, and smoke detectors. Furthermore, "disaster prevention equipment" includes, for example, housings and indicators.

[0081] "Monitoring area" refers to the area monitored by disaster prevention equipment. Specifically, it is a certain range of space, which may include rooms (such as Room A on the 1st floor, Room B on the 1st floor, etc.), corridors, building staircases, etc. In addition, "monitoring area anomaly" means that the state of the monitored area is different from the normal state, which may include fire, gas leak, etc.

[0082] "Outer shell" is, for example, at least some components that cover disaster prevention equipment.

[0083] An "indicator" is an indicator that outputs at least some information about the testing of disaster prevention equipment by emitting light, and is disposed on a housing. Specifically, the concept includes a portion of the indicator, which is configured such that when at least a portion of the housing is covered by the testing equipment to perform the testing of the disaster prevention equipment, at least a portion of the indicator's indicating surface is exposed to the outside of the testing equipment.

[0084] Furthermore, the concept of "indicator" includes, for example, a portion of an indicator protruding from the side of the housing; the concept of an indicator includes a portion of an indicator formed in at least one edge of the front of the housing; the concept of an indicator includes a light guide; and the concept of an indicator includes a thin-walled portion. Additionally, the concept of "indicator's indicating surface" includes, for example, a surface of an indicator that is exposed to the outside of the disaster prevention equipment, emits light, and is visible to the user.

[0085] The concept of a "light guide" includes, for example, a portion formed within a housing that guides light from a light emitter. The concept of a "thin-walled portion" includes, for example, a portion that is thinner than other parts of the housing and is irradiated by light from a light emitter, etc., and also includes a portion that transmits some irradiating light. A "light emitter" is, for example, a unit that outputs light.

[0086] Furthermore, in the various embodiments shown below, the case where the "disaster prevention equipment" is a thermal detector will be described, and in particular, in the first embodiment, the case where the indicator is a light guide will be described, and in the second embodiment, the case where the indicator is a thin-walled portion will be described.

[0087] [Details of the specific embodiments]

[0088] The specific details of the specific embodiments will be described below.

[0089] (First Specific Embodiment)

[0090] First, a first specific embodiment will be described. In this specific embodiment, the case where the indicator is a light guide will be described.

[0091] (Configuration - Detector)

[0092] First, the structure of the detector in this specific embodiment will be described. Figure 1 This is a perspective view of the detector according to a specific embodiment of the present invention. Figure 2 This is a plan view of the detector. Figure 3 This is a side view of the detector. Figure 4 It is along Figure 2 A cross-sectional view of section line AA. Incidentally, in each drawing, the Z-axis, and the X and Y axes orthogonal to the Z-axis, will be described as representing the vertical and horizontal directions, respectively. Furthermore, for example, terms such as "front," "rear," and "side" will be used to describe components of detector 100. Specifically, when detector 100 is mounted on the connecting object 900, which is a ceiling surface, the portion of detector 100 located on the floor surface side (relative to the side of detector 100 opposite to the connecting object 900) Figure 3The -Z direction) is referred to as the "front part", while the part of the detector 100 relative to the connected object 900 as the ceiling surface ( Figure 3 The area in the +Z direction is referred to as the "rear portion". Additionally, the outer peripheral surface of the detector 100, which is connected to both the "front portion" and the "rear portion", is the "side portion". Incidentally, the definitions of "front portion", "rear portion" and "side portion" are the same in the second embodiment.

[0093] Figures 1 to 4 The detector 100 in each diagram is a disaster prevention device; specifically, it is a thermal detector for detecting heat, for example, using... Figure 3 The connector 101 of the detector 100 is mounted on a connection object 900 (e.g., a so-called "detector base," the detailed structure of which is not shown) that serves as a ceiling surface. As an example, it includes... Figure 1 The outer casing 11, the protective part 12 and the protective part 13, and Figure 4 The thermal resistor 14 and the light emitter 15.

[0094] (Configuration - Detector - Housing)

[0095] Figure 1 The housing 11 covers at least a portion of the components of the detector 100. The specific type or configuration of the housing 11 can be any type or configuration; however, for example... Figure 3 As shown, the housing 11 includes a cylindrical portion whose diameter remains constant as it extends away from the connecting portion 101, and a tapered portion whose diameter decreases as it extends away from the connecting portion 101. It has light-shielding properties (except for certain portions) and includes... Figure 2 The light guide 111 and the operation hole 112. Incidentally, "light blocking property" is the ability to block light, and its concept, for example, refers to the ability of the housing 11 to prevent light from passing through from the inside to the outside.

[0096] The light guide 111 is the aforementioned indicator and light guide. The specific type or configuration of the light guide 111 can be arbitrary; however, for example, the light guide 111 is formed within a portion of the housing 11 and can be made of any material to function as a light guide for guiding and emitting light. The light guide 111 is formed separately from the light-shielding portion of the housing 11 and allows light to pass through from the interior of the housing 11 to the exterior. Furthermore, in the light guide 111, for example, the indicator surface (exposed to…) Figure 2 and Figure 3 The outer surface of the detector 100 shown extends from the front side (-Z direction) of the housing 11 to the side side (+X direction or -X direction) of the housing 11, as... Figure 2As shown, two light guides 111 are provided. When viewed from the front side of the housing 11, the indicator surface of the light guide 111 is linear in shape, and the light guide 111 is positioned corresponding to the operation hole 112.

[0097] The operation hole 112 is an operation part for physically operating the detector 100. The specific type or configuration of the operation hole 112 is any type or configuration; however, the operation hole 112 is, for example, a hole that allows a protrusion of a predetermined clamp to be inserted therein to rotate the housing 11 of the detector 100 relative to the connection part 101.

[0098] (Configuration - Detector - Protection Unit)

[0099] Figure 1 The protective portion 12 is a detector component protector. The "detection component protector" houses and protects, for example, the thermal resistor 14, which serves as a detector component. The specific type or configuration of the protective portion 12 can be any type or configuration; however, for example, the protective portion 12 is formed within a part of the housing 11 and can be made of any material to function as a light guide for directing and emitting light, formed separately from the light-shielding portion of the housing 11, and allowing light to pass through the housing 11 from the inside out. Additionally, for example, it protects... Figure 4 The protective portion 12 of the thermal resistor 14 has a hollow portion for housing the thermal resistor 14. The protective portion 12 protrudes from the outer casing 11 to the opposite side (-Z direction) of the connecting portion 101, is disposed at the center of the outer casing 11 along the widening direction of the outer casing 11 (parallel to the XY plane), and is integrally formed with the light guide portion 111. In addition, the protective portion 12 includes, for example, Figure 1 The frame portion 121 and the opening portion 122, and Figure 4 The beam splitter 123.

[0100] The frame portion 121 is, for example, a portion that forms at least a part of the shape of the protective portion 12, and includes a circular member and six support members. The circular member forms the front end (-Z direction) of the detector 100, and the support members are located between the circular member and the housing 11 and support the circular member.

[0101] The opening 122 is, for example, the part where hot air enters and exits the thermal resistor 14 relative to the hollow part of the protective part 12. Six openings 122 are provided and separated by the six support members of the frame part 121.

[0102] The beam splitter 123 is, for example, the part that refracts, disperses, or reflects the light output from the light emitter 15, and is the part facing the light emitter 15.

[0103] (Configuration - Detector - Protection Unit)

[0104] Figure 1The protective part 13 is a protector that prevents a contact object from contacting the thermal resistor 14 housed in the protective part 12. Incidentally, "contact object" refers to the object that the protective part 13 prevents from being touched, and the concept of a contact object includes, for example, a user's finger. The specific type or configuration of the protective part 13 can be any type or configuration; however, the protective part 13 is, for example, a protrusion provided in the opening 122.

[0105] (Configuration - Detector - Thermoresistor)

[0106] Figure 4 The thermal resistor 14 is a detection component. A "detection component" is, for example, a component that detects a physical quantity of a detected object. A "physical quantity of a detected object" refers, for example, a quantity that can be generated or changed due to an anomaly in the monitored area; as an example, this concept includes temperature caused by heat or hot airflow. The specific type or configuration of the thermal resistor 14 is any type or configuration; however, the thermal resistor 14 detects temperature, for example, caused by heat or hot airflow. The protruding direction of the thermal resistor 14 is orthogonal to the width direction (Z-axis direction) of the housing 11, and the thermal resistor 14 is housed within the protective portion 12.

[0107] (Configuration - Detector - Light Emitter)

[0108] Figure 4 The light emitter 15 is the light emitter described above. The specific type or configuration of the light emitter 15 is any type or configuration; however, for example, the light emitter 15 causes the light guide 111 and the protection 12 to emit light and outputs the light to the beam splitter 123, and the light emitter 15 may be composed of a light-emitting diode or the like.

[0109] (Emission of light)

[0110] Next, the emitted light of the detector 100 thus configured will be described. Incidentally, the detector 100 can emit light at any time, for example, when it outputs information about the test status of the detector 100 at any time, or assuming that the detector 100 determines a fire has occurred based on the heat temperature detected by the thermal resistor 14. Incidentally, since the same process as in related art applies to the process by which the detector 100 determines a fire, its description will not be repeated. Figure 5 It is as shown Figure 4 Example diagram of the light path.

[0111] Figure 5 The control unit (not shown) of the detector 100 causes the light emitter 15 to output light. At this time, as Figure 5 As shown, light from the light emitter 15 is refracted, dispersed, or reflected by the beam splitter 123, and then guided to the light guide 111 and the protective part 12, which are integrated as a whole. Incidentally, for ease of description, in... Figure 5Only the light path from the light emitter 15 on the left side of the diagram is shown, but in reality, light also exits from the light emitter 15 on the right side of the diagram and is then guided to the light guide 111 and the protection section 12, which are integrated as a whole. Therefore, Figure 1 The light guide 111 and the protective part 12, which are integrated as a whole, emit light.

[0112] (test)

[0113] Next, the tests performed on the detector 100 configured in this manner will be described. "Tests" refers to testing the performance of the detector 100. Incidentally, the specific content of the tests on the detector 100 can be anything; however, for example, a test will be described to determine whether heat applied by the detector 100 is detected, when heat is applied to the detector 100 to simulate a fire using the test equipment described later. For example, the control unit of the detector 100 will be described below as being configured to obtain the temperature detection result of the thermal resistor 14, indicating that a fire has been detected when the obtained temperature is a threshold or higher, and utilizing the... Figure 4 The light emitter 15 continues to output red light to indicate that the detector 100 has detected a fire during the test.

[0114] Figure 6 This is a side view showing the test equipment and detector. Figure 7 It is relative to Figure 4 The cross-sectional view of the test fixture, and Figure 8 It is relative to Figure 4 A cross-sectional view of the test adapter. Incidentally, for ease of description, in Figure 7 and 8 The test fixture 81 and test adapter 82 are shown in the diagram using alternating long and short dashed lines. Additionally, in... Figure 7 and 8 In the diagram, a portion of the detector 100 is housed within the hollow section inside the test fixture 81 and test adapter 82; it is not actually visible, but is shown as a solid line for ease of description. (Using...) Figure 6 The test equipment 800 performs the test of the detector 100.

[0115] (Testing - Test Equipment)

[0116] Test equipment 800 is a device for testing detector 100, including, for example, […]. Figure 6 The handle and test fixture 81 shown, and optionally including Figure 8 Test adapter 82.

[0117] (Testing - Test Equipment - Test Fixtures)

[0118] The test fixture 81 is the aforementioned test device, specifically located at the front end of the rod-shaped handle of the test device 800. For example, it is a cylindrical shape with a hollow portion, housing at least a portion of the detector 100 (e.g., the protective part 12, etc.) within the hollow portion. The hollow portion is used to apply heat and is made of metal. The size of the test fixture 81 is arbitrary; however, as... Figure 7 As shown, the case where the outer diameter of the test fixture 81 is larger than the outer diameter of the detector 100 and the inner diameter of the test fixture 81 is smaller than the outer diameter of the detector 100 will be described.

[0119] (Test - Test Equipment - Test Adapter)

[0120] Figure 8 The test adapter 82 is the aforementioned test device, specifically, it can be detachably installed on... Figure 6 The front end side (+Z direction) of the test fixture 81, for example, for converting the diameter of the test fixture 81 to a diameter smaller than that of the test fixture 81, has a cylindrical shape, is made of metal, and includes a hollow portion that is continuous with the hollow portion of the test fixture 81 during installation. The size of the test adapter 82 can be any size, however... Figure 8 As shown, the case where the outer diameter of the test adapter 82 is smaller than the outer diameter of the detector 100 will be described.

[0121] (Test - Details)

[0122] Next, we will explain the testing scenarios without using test adapter 82 and the testing scenarios using test adapter 82.

[0123] First, let's explain the scenario where testing is not performed using test adapter 82, such as... Figure 7 As shown, with the test fixture 81 in contact with the detector 100 and a portion of the detector 100 (e.g., the protective part 12, etc.) housed in the hollow portion of the test fixture 81, heat is applied from the hollow portion side of the test fixture 81. In this situation, the control unit of the detector 100 detects a fire and... Figure 4 The light emitter 15 outputs red light. Furthermore, as described above, the red light is guided to the light guide 111 and the protective portion 12, so that the light guide 111 and the protective portion 12 emit light as a single unit. At this time, as... Figure 7 As shown, the light guide 111 and part of the protective part 12 are obscured by the test fixture 81 and cannot be seen from the outside. However, since a part of each light guide 111 located on the side of the housing 11, namely the side part 111A, is exposed, the red light emitted from the side part 111A can be seen. Therefore, the user can identify information about the test by observing the red light emitted from the side part 111A.

[0124] Next, we will explain the testing process using test adapter 82, such as... Figure 8 As shown, with the test adapter 82 in contact with the detector 100 from the front side and a portion of the detector 100 (e.g., the protective part 12, etc.) housed in the hollow portion of the test adapter 82, heat is applied from the hollow portion side of the test adapter 82. In this situation, the control unit of the detector 100 detects a fire and... Figure 4 The light emitter 15 outputs red light. Furthermore, as described above, the red light is guided to the light guide 111 and the protective portion 12, so that the light guide 111 and the protective portion 12 emit light as a single unit. At this time, as... Figure 8 As shown, the light guide 111 and part of the protective part 12 are obscured by the test fixture 81 and cannot be seen from the outside. However, the side portion 111A, which is part of each light guide 111, is located on the side of the housing 11 and the leading edge portion 111B, which is formed on the edge of the front part of the housing 11 and is part of each light guide 111, is exposed. Therefore, the red light emitted from the side portion 111A and the leading edge portion 111B can be seen. For this reason, the user can identify information about the test by observing the red light emitted from the side portion 111A and the leading edge portion 111B.

[0125] (Effects of specific embodiments)

[0126] In this manner, according to this specific embodiment, when at least a portion of the housing 11 is covered by the test fixture 81 or the test adapter 82 for testing the detector 100, at least a portion of the indicating surface of the light guide portion 111, which serves as an indicator, is exposed to the outside of the test fixture 81 or the test adapter 82. Therefore, for example, even when at least a portion of the detector 100 is covered by the test fixture 81 or the test adapter 82, a portion of the light guide portion 111 can be seen, and thus information about the test can be identified.

[0127] In addition, since the indicator includes a side portion 111A formed in, for example, the side portion of the housing 11, the indicator can be seen in any direction relative to the detector 100, so information about the test can be reliably identified.

[0128] Furthermore, since the indicator includes, for example, a leading edge portion 111B formed in the edge portion of the front part of the housing 11, the indicator can be seen even from directly below the detector 100, thus allowing information about the test to be reliably identified.

[0129] Furthermore, since the indicator is, for example, part of the light guide 111, the freedom of the mounting position of the light emitter 15, which serves as the light source of the indicator, can be increased, thereby improving the design freedom of the detector 100.

[0130] (Second Specific Embodiment)

[0131] Next, a second specific embodiment will be described. In this specific embodiment, the case where the indicator is a thin-walled portion will be described. Incidentally, unless otherwise stated, it is assumed that each configuration of the second specific embodiment is equivalent to each configuration with the same name in the first specific embodiment.

[0132] (Configuration - Detector)

[0133] First, the structure of the detector in this specific embodiment will be described. Figure 9 This is a perspective view of the detector according to a specific embodiment of the present invention. Figure 10 This is a plan view of the detector. Figure 11 It is a side view of the detector, and Figure 12 It is along Figure 10 The cross-sectional view of section line BB. The detector 200 in each diagram is a disaster prevention device, specifically a thermal detector for detecting heat, for example, by... Figure 11 The connector 201 of the detector 200 is mounted on the connection object 900, which is a ceiling surface. As an example, it includes... Figure 9 The outer casing 21, the protective part 22 and the protective part 23, and Figure 12 The thermal resistor 24 and the light emitter 25.

[0134] (Configuration - Detector - Housing)

[0135] Figure 9 The housing 21 covers at least a portion of the components of the detector 200. The specific type or configuration of the housing 21 can be any type or configuration; however, for example, the housing 21 may block all or only a portion of the light and include... Figure 10 The thin-walled portion 211.

[0136] The thin-walled portion 211 is an indicator and is thinner than the other parts of the housing 21. The specific type or configuration of the thin-walled portion 211 is any type or configuration; however, the thin-walled portion 211 is, for example, thin enough to transmit at least a portion of the irradiated light (i.e., thin enough to block only a portion of the irradiated light), and is integrally formed with the other parts of the housing 21. The thin-walled portion 211 extends from the front side (-Z direction) of the housing 21 towards the side side (+X direction or -X direction) of the housing 21. Two thin-walled portions 211 are provided, such as... Figure 10 As shown, when viewed from the front side of the outer casing 21, the thin-walled portion 211 has a linear shape.

[0137] Incidentally, "other parts of the housing 21" are a part of the housing 21, specifically the parts of the housing 21 other than the thin-walled part 211, such as the parts that are thick enough to block all the light.

[0138] (Configuration - Detector - Protection Unit)

[0139] Figure 9 The protective portion 22 is the aforementioned protector for the detection component. The specific type or configuration of the protective portion 22 can be any type or configuration; however, for example, the protective portion 22 is formed within a part of the housing 21 and can be made of any material to function as a light guide for directing and emitting light. The protective portion 22 is formed separately from the light-shielding portion of the housing 21 and allows light to pass through from the interior of the housing 21 to the exterior. Additionally, the protective portion 22, for example, protects... Figure 12 The thermal resistor 24 and the protection part 22 include, for example, the thermal resistor 24 and the protection part 22. Figure 10 The frame portion 221 and the opening portion 222, and Figure 12 The beam splitter 223. Incidentally, the structures of the frame portion 221, the opening portion 222, and the beam splitter 223 are the same as those of the counterparts in the first specific embodiment, so their description is omitted.

[0140] (Configuration - Detector - Protective Unit, Thermal Resistance, Light Emitter)

[0141] because Figure 9 Protective Department 23 and Figure 12 The configuration of the thermal resistor 24 and the light emitter 25 is the same as that of the counterpart with the same name in the first specific embodiment, and therefore their description will not be repeated.

[0142] (Emission of light)

[0143] Next, the emitted light of the detector 200 configured in this way will be explained. Figure 13 It is as shown Figure 12 Example diagram of the light path.

[0144] Figure 13 The control unit (not shown) of the detector 200 causes the light emitter 25 to output light. In this case, the light from the light emitter 25 is refracted, dispersed, or reflected by the beam splitter 223, such as... Figure 13 As shown, light illuminates the entire thin-walled portion 211 and is guided to the entire protective portion 22. Incidentally, for ease of description, in... Figure 13 Only the light path from the light emitter 25 on the left side of the figure is shown, but in reality, light also exits from the light emitter 25 on the right side of the figure, illuminating the entire thin-walled portion 211 and being guided to the entire protective portion 22. Then, Figure 10 The thin-walled portion 211 and the protective portion 22 emit light as a whole.

[0145] (test)

[0146] Next, the tests performed on the detector 200 configured in this manner will be described. Figure 14It is relative to Figure 12 A cross-sectional view of the test fixture. Figure 15 It is relative to Figure 12 The diagram shows a cross-sectional view of the test adapter. Here, we will describe both the case where testing is performed without test adapter 82 and the case where testing is performed with test adapter 82.

[0147] First, let's explain the scenario where testing is not performed using test adapter 82, such as... Figure 14 As shown, with the test fixture 81 in contact with the detector 200 and a portion of the detector 200 (e.g., the protective part 22, etc.) housed in the hollow portion of the test fixture 81, heat is applied from the hollow portion side of the test fixture 81. In this situation, the control unit of the detector 200 detects a fire and... Figure 13 The light emitter 25 outputs red light. Furthermore, as described above, the entire thin-walled portion 211 is illuminated by red light, which is then guided to the entire protective portion 22, causing the thin-walled portion 211 and the protective portion 22 to emit light as a single unit. In this case, as... Figure 14 As shown, a portion of the thin-walled portion 211 and the protective portion 22 are obscured by the test fixture 81 and cannot be seen from the outside. However, since a portion of each thin-walled portion 211 located on the side of the housing 21, namely the side portion 211A, is exposed, the red light emitted from the side portion 211A can be seen. Therefore, the user can identify information about the test by observing the red light emitted from the side portion 211A.

[0148] Next, we will explain the testing process using test adapter 82, such as... Figure 15 As shown, with the test adapter 82 in contact with the detector 200 and a portion of the detector 200 (e.g., the protective part 22, etc.) housed in the hollow portion of the test adapter 82, heat is applied from the hollow portion side of the test adapter 82. In this situation, the control unit of the detector 200 detects a fire and... Figure 13 The light emitter 25 outputs red light. Furthermore, as described above, by irradiating the entire thin-walled portion 211 with red light and then guiding the red light to the entire protective portion 22, the thin-walled portion 211 and the protective portion 22 emit light as a single unit. In this case, as... Figure 15As shown, a portion of the thin-walled portion 211 and the protective portion 22 are obscured by the test fixture 81 and cannot be seen from the outside. However, since the side portion 211A, where a portion of each thin-walled portion 211 is formed on the side of the outer casing 21, and the leading edge portion 211B, formed in the edge portion of the front part of the outer casing 21, are exposed, the red light emitted from the side portion 211A and the leading edge portion 211B can be seen. Therefore, the user can identify information about the test by observing the red light emitted from the side portion 211A and the leading edge portion 211B.

[0149] (Effects of specific embodiments)

[0150] Thus, according to this specific embodiment, since the indicator is, for example, part of the thin-walled portion 211, there is no need to provide additional components for emitting light, thereby reducing the number of components and lowering costs.

[0151] [Examples of modifications to specific embodiments]

[0152] The specific embodiments of the present invention have been described above. However, within the scope of the technical concepts of the invention as described in the claims, any changes or modifications can be made to the specific structure, units, and parts of the present invention. Such modifications will be described below.

[0153] (Regarding technical issues and the effects of the invention)

[0154] First, the technical problems and effects of the present invention are not limited to the above-mentioned contents, and may vary depending on the details of the implementation environment or configuration of the present invention. Furthermore, it may only solve some of the above-mentioned problems, or only obtain some of the above-mentioned effects.

[0155] (On separation and integration)

[0156] Furthermore, the above configuration is conceptual and does not necessarily require the physical configuration shown in the figures. That is, the specific ways in which the parts are separated and integrated are not limited to those shown in the figures, and they can be configured, in whole or in part, to be functionally or physically separated or integrated in any unit.

[0157] (Regarding the light-conducting section and the thin-walled section)

[0158] Additionally, in the first specific embodiment, such as Figure 2 As shown, the case where the light-emitting surface of the light guide 111 is linear when viewed from the front side of the housing 11 has been described, but the present invention is not limited thereto. For example, when viewed from the front side of the housing 11, the light guide 111 may have a curved shape (e.g., an overall S-shape). Incidentally, in the second embodiment... Figure 10The thin-walled portion 211 can also have a curved shape (e.g., S-shaped overall).

[0159] Furthermore, in the specific embodiment, the case of providing two light guide portions and two thin-walled portions has been described, but the present invention is not limited thereto. For example, the light guide portions and thin-walled portions may be omitted. Alternatively, one light guide portion and one thin-walled portion may be provided, or three or more light guide portions and three or more thin-walled portions may be provided.

[0160] (Regarding the protruding part)

[0161] Alternatively, protrusions can be provided in the detectors of various specific embodiments for use as indicators. Figure 16 This is a plan view of the detector. Figure 17 This is a view of the test fixture, relative to along Figure 16 A cross-sectional view of section line CC. The specific method for installing the protrusion is any method, however, as... Figure 16 As shown, by extending the first specific embodiment Figure 2 The length of the light guide 111 in the X-axis direction can also be such that the front end of the light guide 311, which has the same structure as the light guide 111, is constructed as a protrusion 311A. The detector 300 configured in this way, when... Figure 17 When the test fixture 81 is set up as shown, the protrusion 311A, which is part of the light guide 311, is exposed from the test fixture 81, so that when the protrusion 311A ​​emits light from the light emitter during the test, the user can see the emitted light. In this structure, the protrusion 311A, which serves as an indicator, protrudes from the side of the housing of the detector 300. For example, the protrusion 311A, which serves as an indicator, can be clearly seen, and therefore information about the test can be reliably identified.

[0162] Additionally, for example, in the detector 200 of the second embodiment, with Figure 16 Similar to the detector 300, the protrusion can be formed into an indicator by setting the shape of the housing 21 to have a protrusion and then forming the protrusion into a thin-walled part.

[0163] In addition, for example, an indicator light other than a light guide or thin-walled part (e.g., a projectile-shaped indicator light, the same as in the related art) can be formed on the side of the detector to construct an indicator light as a protrusion.

[0164] (Regarding characteristics)

[0165] Furthermore, the structural features and variations of each specific embodiment can be combined arbitrarily. For example, Figure 2 The detector 100 can be configured to have thin-walled portions provided on the housing 11, which emit light together with the light guide portion 111, or Figure 10The detector 200 can also be configured to have a light guide on the housing 11, and the light guide emits light together with the thin-walled portion 211.

[0174] (The beneficial effects of annotation)

[0175] According to the disaster prevention equipment described in Note 1, when at least a portion of the housing is covered by the test equipment for testing the disaster prevention equipment, at least a portion of the indicator surface is exposed to the outside of the test equipment. Therefore, even when at least a portion of the disaster prevention equipment is covered by the test equipment, a portion of the indicator can be seen, thereby enabling the identification of information related to the test.

[0176] According to the disaster prevention equipment described in Note 2, the indicator is indeed visible, for example, because the indicator protrudes from the side of the housing, thus enabling reliable identification of information about the test.

[0177] According to the disaster prevention equipment described in Note 3, since the indicator is formed on the side of the housing, the indicator can be seen from any direction relative to the disaster prevention equipment, thus ensuring the accurate identification of information about the test.

[0178] According to the disaster prevention equipment described in Note 4, since the indicator is formed on the edge of the front part of the housing, for example, the indicator can be seen even from directly below the disaster prevention equipment, so information about the test can be reliably identified.

[0179] According to the disaster prevention equipment described in Note 5, since the indicator is part of the light guide, the degree of freedom in the installation position of the indicator's light source (e.g., light emitter) can be increased, thereby improving the design freedom of the disaster prevention equipment.

[0180] According to the disaster prevention equipment described in Note 6, since the indicator is part of the thin-walled section, for example, there is no need to set up a separate component for emitting light, thus reducing the number of components and lowering costs.

[0181] According to the disaster prevention equipment described in Note 7, since the disaster prevention equipment is at least a thermal detector, it is possible to provide information about the test even when at least a portion of the disaster prevention equipment is covered by the test equipment.
