It is possible to switch between the non-suppressed state. More specifically, as shown in FIG. 2B, in the deterrent means 32 in the deterrent state, the deterrent plate 32b that rotates with the rotation operation of the deterrent means 32 has the upper surface portion 16a (or FIG. In the state of the above, the recess 16c of the lower surface portion 16b) is located at a position where it abuts on the wall portion separating the recess 16c and the recess 16d, thereby suppressing the opening operation of the lid portion 14. On the other hand, the deterrent means 32 in the non-deterrent state is rotated from the state shown in FIG. 2B, and the deterrent plate 32b is a recess 16c of the upper surface portion 16a of the main body portion 16 (or the lower surface portion 16b in the state of FIG. 3). The lid portion 14 can be opened by being rotated until it is located at the lower position in the drawing. The deterrent means 32 preferably has a structure that can be operated only by, for example, a special tool so that the person who operates it is restricted.

As described above, the mounting plate 34 fixed to the lid portion 14 is equipped with an emergency stop button 40, a return button 42, a stop button 44, and the like, as well as a holding mechanism 50 and an alarm means 80. The emergency stop button 40 is a mechanical button for starting the alarm by the alarm means 80, and is pressed from the front side of the lid 14 via the button cover 40a. The return button 42 is a mechanical button for stopping the alarming via the alarming means 80, and is pressed from the front side of the lid portion 14 with the lid 42a open.

It is transmitted, and in this embodiment, it is configured by a magnetic proximity switch. Specifically, the transmission means 54 composed of the magnetic proximity switch generates a magnetic field between the detection units 54a and 54b by the built-in magnet, and detects the approach of the metal depending on the presence or absence of the change in the magnetic field. That is, the transmission means 54 is in a position where the metal operating member 52 does not affect the magnetic field between the detection units 54a and 54b when the operating member 52 is in the second position P2 shown in FIG. 4A. Therefore, it is determined that the operating member 52 is at a position (second position P2) away from the transmission means 54. In this case, the transmission means 54 electrically outputs information indicating that the monitoring state is maintained to the alarm means 80. On the other hand, in the transmission means 54, when the operating member 52 is at the first position P1 shown in FIG. 4B, the side plate portion 52a of the operating member 52 is located between the detecting portions 54a and 54b, and the detecting portions 54a and 54b. Since the magnetic field between them changes, it is determined that the operating member 52 is at a position close to the transmission means 54 (first position P1). In this case, the transmission means 54 electrically outputs information indicating that the notification state is maintained to the notification means 80.

The urging means 56 urges the operating member 52 to the first position P1 and includes a torsion spring 58 inserted through the shaft portion 76.

The transmission shaft 93 has an operating plate 92 attached to one end and a bevel gear 91 attached to the other end, and rotates the bevel gear 91 as the operating plate 92 rotates. As shown in FIGS. 7 and 8, the return button 42 is urged by the coil spring 43 in a direction opposite to the moving direction by the pressing operation (upward direction in FIG. 8).

Next, referring to FIG. 4 again, the issuing means 80 issues an alarm when receiving information indicating the issuing state from the transmitting means 54, and receives information indicating the monitoring state from the transmitting means 54. In this embodiment, the transmission unit 82, the lighting unit 84, and the sounding unit 86 are included. The transmission unit 82 transmits a train emergency stop signal to the outside when the alarm is being issued, and although a specific description is withheld, it is composed of various electric circuits and electric components. The lighting unit 84 emits light when the alarm is being issued to issue an alarm. In this embodiment, the lighting unit 84 emits an alarm by lighting or blinking a plurality of LEDs 85 (see FIG. 2A). Do. In addition, the sounding unit 86 generates a sound when the alarm is being issued to issue an alarm, and in this embodiment, the buzzer 87 (see FIG. 2A) is used to issue the alarm. It is configured in.

Note that the configurations shown in FIGS. 1 to 8 show an example of the configuration of the train emergency stop switch 10 according to the embodiment of the present invention, and do not limit the configuration of the train emergency stop switch 10. .. For example, the opening / closing mechanism 20 has a structure in which the first member 22 is provided at either the left or right end in FIG. 2A and the second member 24 is provided at both the left and right ends in FIG. 2A. It may be present, or it may have a connection structure other than the hinge mechanism. Further, the holding mechanism 50 may have a configuration different from the above as long as it mechanically holds the alarm state and the monitoring state, and the deterrent means 32 suppresses the opening operation of the lid portion. If so, the configuration may be different from the above. Further, the transmission means 54 may also be composed of a member other than the magnetic proximity switch.

By the way, according to the embodiment of the present invention having the above configuration, the following effects can be obtained. That is, as shown in FIGS. 1 and 2, the train emergency stop switch 10 according to the embodiment of the present invention includes a housing 12, an emergency stop button 40, a return button 42, a holding mechanism 50, and an alarm means 80. I'm out. The housing 12 accommodates each component and is provided with a mounting member 36 or the like for mounting on a platform. The emergency stop button 40 is operated by a station employee or the like to start an alarm including transmission of a train emergency stop signal, that is, an alarm is issued from a monitoring state waiting without issuing an alarm. It is a button for switching to a state, and is provided at a position that can be operated from the front side (right side in FIGS. 1B and 2B) of the housing 12 in the state of being installed on the platform. Further, the return button 42 is a button for canceling the alarm, that is, switching from the alarm state in which the alarm is issued to the monitoring state in which the alarm is not issued, by being operated by a station employee or the like. , Like the emergency stop button 40, it is provided at a position that can be operated from the front side of the housing 12.

On the other hand, the holding mechanism 50 mechanically holds the alarming state and the monitoring state in response to the operation of the emergency stop button 40 and the return button 42. That is, when the emergency stop button 40 is operated, the holding mechanism 50 mechanically holds the alarm state until the return button 42 is operated, and when the return button 42 is operated, the holding mechanism 50 mechanically holds the alarm state. After that, the monitoring state is mechanically maintained until the emergency stop button 40 is operated.

Since the configuration is as described above, the train emergency stop switch 10 according to the embodiment of the present invention mechanically holds the alarm state and the monitoring state by the holding mechanism 50 without depending on the electrical configuration. Therefore, even if an electrical failure such as a momentary power failure occurs, the alarm state and the monitoring state can be reliably maintained. Further, since no electrical contact is used to maintain the state, welding of the contact does not occur due to a large current, wear, or the like. As a result, it is possible to prevent the train emergency stop switch 10 from malfunctioning, and it is possible to improve the reliability of the train emergency stop switch 10. Moreover, not only the emergency stop button 40 for starting the alarm but also the return button 42 for canceling the alarm is provided at a position that can be operated from the front side of the housing 12. Therefore, the operability is excellent, and for example, the emergency stop button 40 and the return button 42 can be operated without any problem even when the platform is installed so as to be embedded in a pillar of the platform.

Further, in the train emergency stop switch 10 according to the embodiment of the present invention, the rectangular parallelepiped housing 12 has a lid portion 14 forming the front side and a rear side (FIGS. 1B and 2B). It has a main body 16 that constitutes (left side). That is, both the lid portion 14 and the main body portion 16 form a rectangle when viewed from the front. The lid portion 14 can be opened and closed and detachably attached to the main body portion 16 via an opening / closing mechanism 20, and a wiring port 30 for drawing wiring such as a power supply into the housing 12 is provided. The opening / closing mechanism 20 for attaching the lid portion 14 to the main body portion 16 is composed of a first member 22 provided at any end of the lid portion 14 and a second member 24 provided on the main body portion 16. To.

Here, as shown in FIGS. 1 and 2, the lid portion 14 forming the front side of the rectangular parallelepiped housing 12 and the main body portion 16 forming the rear surface side are overlapped so as to correspond to each other in the front view shape. Even if only the main body 16 is rotated by 180 ° with the axis S orthogonal to the rear surface of the housing 12 as the rotation axis from the state of being arranged and arranged, the front view shape corresponds again as shown in FIG. It will be arranged properly. Therefore, the second member 24 provided on the main body 16 corresponds to the first member 22 of the lid 14 when the lid 14 and the main body 16 are overlapped and arranged so as to correspond to the front view shape. It is provided at both the position where the lid portion 14 is to be used and the position corresponding to the first member 22 of the lid portion 14 when only the main body portion 16 is rotated from that state as described above. That is, as shown in FIG. 2A, the second member 24 is provided at a point-symmetrical position centered on the rotation axis S when viewed from the front of the main body 16.

With the above configuration, the lid portion 14 and the main body portion 16 constituting the housing 12 can be attached in the following two forms. That is, in one form, the first member 22 provided on the lid portion 14 and the one second member 24 provided on the main body portion 16 are assembled via an opening / closing mechanism 20. Can be installed. Further, in the other form, the first member 22 provided on the lid portion 14 and the other second member 24 provided on the main body portion 16 in a state where only the main body portion 16 is rotated by 180 ° from one form. It is attached via an opening / closing mechanism 20 which is assembled and configured. Therefore, for example, even if the position of the wiring port 30 provided in the main body 16 is restricted, the wiring port 30 is provided in only one place in the main body 16. It is possible to flexibly correspond to two positions, that is, the position of the wiring port 30 of the main body 16 in one mounting form and the position of the wiring port 30 of the main body 16 in the other mounting form. it can. As a result, it is possible to significantly reduce the cost associated with the design change such as the position change of the wiring port 30.

Further, in the train emergency stop switch 10 according to the embodiment of the present invention, the main body 16 constituting the rear surface side of the housing 12 has a box shape in which the front side of the housing 12 is open, and the platform. The position of each part is determined as follows in the front view (see FIG. 2A) of the housing 12 installed in. Specifically, the first member 22 that constitutes the opening / closing mechanism 20 is provided on the lower end side of the lid portion 14, and the second member 24 that also constitutes the opening / closing mechanism 20 is the upper surface portion 16a and the lower surface portion 16b of the main body portion 16. It is provided on both sides. That is, the lid portion 14 has a lower end side via an opening / closing mechanism 20 composed of a first member 22 provided on the lower end side thereof and a second member 24 provided on the lower surface portion 16b of the main body portion 16. It is attached to the main body 16 so as to be opened from the upper end side as a shaft. At this time, the wiring port 30 provided on the upper surface portion 16a of the main body portion 16 is located on the upper side of the main body portion 16.

On the other hand, when the lid portion 14 is attached in a state where the main body portion 16 is rotated by 180 ° with the axis S as the rotation axis (see FIG. 3), the lid portion 14 has the first member 22 provided on the lower end side thereof and the main body. It is attached to the main body 16 so as to be opened from the upper end side with the lower end side as an axis via an opening / closing mechanism 20 composed of a second member 24 provided on the upper surface portion 16a of the portion 16. At this time, the wiring port 30 provided on the upper surface portion 16a of the main body portion 16 is located on the lower side of the main body portion 16 opposite to that before the rotation of the main body portion 16. That is, although the wiring port 30 is provided on the upper surface portion 16a of the main body portion 16, the wiring port 30 can be used before or after the main body portion 16 is rotated by 180 °. It can correspond to both the form located on the upper side and the form located on the lower side. Here, the wiring drawn into the housing 12 through the wiring port 30 is often routed from above or below on the platform. Therefore, since the wiring port 30 is compatible with both the upper side and the lower side, it can be adapted to many installation locations.

Further, in the train emergency stop switch 10 according to the embodiment of the present invention, as shown in FIG. 2, both the holding mechanism 50 and the alarming means 80 are fixed to the lid portion 14 via the mounting board 34. It is a thing. Therefore, the lid portion 14 detachably attached to the main body portion 16 via the opening / closing mechanism 20 can be removed from the main body portion 16 with the holding mechanism 50 and the alarm means 80 fixed. it can. Here, the lid portion 14 constituting the front side of the housing 12 includes a structure for operating the emergency stop button 40 and the return button 42, and includes a plurality of members used in the holding mechanism 50 and the alarm means 80. It is provided. Therefore, assuming that the holding mechanism 50 and the alarming means 80 are fixed to the main body 16, when the main body 16 is rotated by 180 ° as described above, the holding mechanism 50 and the alarming means 80 In order to correspond the position with the member provided on the lid portion 14, it is necessary to temporarily remove the holding mechanism 50 and the alarming means 80 from the main body portion 16 and reattach them after the main body portion 16 rotates, additional parts, and the like. Is expected to be.

However, in the train emergency stop switch 10 according to the embodiment of the present invention, as described above, since the holding mechanism 50 and the alarm means 80 are fixed to the lid portion 14, the lid portion 14 and the main body portion 16 are connected. Only the main body 16 can be rotated while the holding mechanism 50 and the alarming means 80 are held by the lid 14 after being separated. As a result, of the second members 24 provided at the two locations of the main body 16, the lid portion 14 is attached by using one of the second members 24, and the other second member 24 is used. Switching to the form in which the lid portion 14 is attached can be easily performed without requiring unintentional labor, additional parts, or the like.

Further, as shown in FIG. 2B, the train emergency stop switch 10 according to the embodiment of the present invention has the main body 16 in a state where the lid 14 is attached to the main body 16 via the opening / closing mechanism 20. By providing the lid portion 14 with a deterrent means 32 for suppressing the opening operation of the lid portion 14 with respect to the main body portion 16, the lid portion with respect to the main body portion 16 is prevented from opening the lid portion 14 at an undesired timing. 14 can be reliably held. Moreover, since the deterrent means 32 is provided at a position where it can be operated from the front side, the lid portion 14 can be easily opened by releasing the deterrent state when necessary such as during maintenance. Further, by configuring the opening / closing mechanism 20 with a hinge mechanism, it is possible to facilitate the opening / closing operation of the lid portion 14 and facilitate the separation of the lid portion 14 and the main body portion 16 without using a complicated configuration. Can be done.

Further, in the train emergency stop switch 10 according to the embodiment of the present invention, as shown in FIG. 4, the alarm means 80 has a transmission unit 82 for transmitting a train emergency stop signal to the outside and a lighting unit for generating light. It includes 84 and a sounding unit 86 that generates sound. That is, in addition to the transmission of the train emergency stop signal by the transmission unit 82, the notification means 80 performs a notification using light by the lighting unit 84 and a notification using sound by the sounding unit 86, and the surroundings It conveys to people that the train emergency stop switch 10 has been handled, both by light and sound. Here, since the transmitting unit 82, the lighting unit 84, and the sounding unit 86 are all electrically controlled, the alarming is stopped during a power failure regardless of the alarming state or the monitoring state. .. However, since the operation is performed according to the state of being mechanically held by the holding mechanism 50, the same operation (execution or stop of issuing a report) as before the power failure can be performed after the power is restored.

Further, as shown in FIG. 2, the train emergency stop switch 10 according to the embodiment of the present invention is stopped to stop the sound generation by the sounding unit 86 at a position that can be operated from the front side of the housing 12. A button 44 is provided. When the stop button 44 is operated by a station employee or the like, the sound generation unit 86 stops the generation of sound even if the alarm state is held by the holding mechanism 50. As a result, while the transmission unit 82 continues to transmit the train emergency stop signal and the lighting unit 84 generates light, it is possible to stop only the sound issuance that may sometimes cause discomfort. Further, as shown in FIGS. 1 and 2, a prism 46 for diffusing the light from the lighting unit 84 (LED85) is provided on the front side of the housing 12, and the light generated from the lighting unit 84 is provided.

Further, in the train emergency stop switch 10 according to the embodiment of the present invention, as shown in FIG. 4, the holding mechanism 50 includes an operating member 52 and a transmission means 54, and the operating member 52 is an emergency stop. It is moved to the first position P1 and the second position P2 in response to the pressing operation of the button 40 and the return button 42. More specifically, the operating member 52 is moved to the first position P1 indicating the alarm state in conjunction with the pressing operation of the emergency stop button 40, and indicates the monitoring state in conjunction with the pressing operation of the return button 42. It is moved to the second position P2. That is, the holding mechanism 50 mechanically holds the alarm state and the monitoring state by using the operating member 52 that can move to the first position P1 and the second position P2.

On the other hand, the transmission means 54 electrically supplies information indicating the notification state or the monitoring state to the notification means 80 including the transmission unit 82, the lighting unit 84, and the sounding unit 86, depending on the position of the operating member 52. It is something to convey. That is, when the operating member 52 is in the first position P1, the transmitting means 54 electrically transmits to the reporting means 80 that the operating member 52 is in the alarming state, and the operating member 52 is in the second position P2. When it is at, it electrically transmits to the alarm means 80 that it is in the monitoring state. As a result, the reporting state and the monitoring state are mechanically maintained, and the notification means 80 that issues a notification that requires electrical control such as transmission of a train emergency stop signal is in the reporting state and the monitoring state. Since it is possible to electrically transmit something, it is possible to smoothly start and stop the issuing of the alarm by the issuing means 80.

Here, referring to the case where an instantaneous power failure occurs, as described above, the holding mechanism 50 mechanically holds the alarm state and the monitoring state by using the operating member 52, and the instantaneous power failure occurs. Even so, the position of the operating member 52 does not change before and after the occurrence of the instantaneous power failure. Then, although the transmission means 54 electrically transmits information indicating the alarm state or the monitoring state, it transmits them according to the position of the operating member 52, so that the information is transmitted from the transmission means 54 before and after the occurrence of the instantaneous power failure. The content does not change. Therefore, even if a momentary power failure occurs, before and after the power failure, information indicating the reporting state and the monitoring state can be electrically and accurately transmitted from the transmitting means 54 to the reporting means 80, so that the train emergency stop. It is possible to prevent malfunction of the switch 10.

Further, in the train emergency stop switch 10 according to the embodiment of the present invention, the transmission means 54 is composed of a magnetic proximity switch that detects the approach of the metal operating member 52. For example, the operating member 52 approaches the magnetic proximity switch when it is in the first position P1 indicating the alarm state, and separates from the magnetic proximity switch when it is in the second position P2 indicating the monitoring state. Will be installed. As a result, the magnetic proximity switch detects the change in the magnetic field generated from the magnetic proximity switch when the metal operating member 52 is in the first position P1 approaching, and the operating member 52. Is determined to be approaching, and information indicating the reporting state is transmitted to the reporting means 80. Further, when the magnetic proximity switch is in the second position P2 where the metal operating member 52 is separated, the operating member 52 is separated because the change in the magnetic field generated from the magnetic proximity switch is not detected. It is determined that this is the case, and information indicating the monitoring state is transmitted to the reporting means 80. In this way, by using the magnetic proximity switch as the transmission means 54, the information mechanically held by the operating member 52 can be more reliably and smoothly electrically transmitted to the alarm means 80. It becomes possible to transmit to.

Further, in the train emergency stop switch 10 according to the embodiment of the present invention, the holding mechanism 50 includes an urging means 56, a locking mechanism 60, a releasing mechanism 70, and a moving mechanism 74. The urging means 56 urges the operating member 52 to the first position P1 indicating the alarm state, and the moving mechanism 74 receives the pressing operation of the return button 42 and opposes the urging force by the urging means 56. The operating member 52 is moved from the first position P1 to the second position P2 indicating the monitoring state. Further, the lock mechanism 60 holds the operation member 52 at the second position P2, and the release mechanism 70 receives a pressing operation of the emergency stop button 40 to release the holding state of the operation member 52 by the lock mechanism 60.

That is, when the operating member 52 is held at the second position P2 by the lock mechanism 60 and the holding state is released via the release mechanism 70 by pressing the emergency stop button 40, the urging means 56 Is moved from the second position P2 to the first position P1 by the urging force of. Further, when the return button 42 is pressed while the operating member 52 is in the first position P1, the operating member 52 is moved from the first position P1 to the second position P2 via the moving mechanism 74, and then is then moved. It is held at the second position P2 by the lock mechanism 60.
