Description

  The present invention relates to a wireless microphone for a portable railway that controls a wireless microphone that performs various types of guidance broadcasting and a door closing signal indicator that instructs the conductor to open and close the door when entering or leaving the train at the station platform or when the door is opened or closed. The present invention relates to an improvement of an operation device.

Conventionally, various types of information broadcasting using a wireless microphone have been performed in order to ensure the safety of passengers at the time of entering / exiting a train at a station platform or opening / closing a door.
In addition, when the door is opened and closed, the passengers in the vicinity of the door cannot fully grasp the condition of the passenger, so the station staff can hang it from the ceiling of the platform by operating the door closing signal controller fixedly installed on the pillar of the platform. A door closing signal such as a door closing signal, a door closing confirmation signal, a reopening door signal, and an emergency stop signal is displayed on the door closing signal indicator displayed in a predetermined display pattern and display color. By confirming this, the conductor performs door opening / closing operations and train starting / stopping operations.

However, in the conventional method, in order to display the door closing signal on the door closing signal indicator suspended from the ceiling of the platform, it is necessary to operate the door closing signal operator fixedly installed on the pillar of the home. . However, when the platform is crowded with passengers, such as during morning and evening rush hours, in order to confirm the safety of the passengers, it is necessary to check away from the place where the door closing signal operating device is located.
After confirming safety, the operator will return to the location where the door closing signal operator is located and operate the door closing signal operator. There is a problem that can not be confirmed.

  Further, even in a station platform where the platform itself is curved, in order to confirm the safety of passengers, it is necessary to leave the place where the door closing signal operating device is located. For this reason, as described above, there is a problem that the safety of passengers cannot be sufficiently confirmed while returning to a place where the door closing signal manipulator is located.

  To solve such problems, station staff were fixedly installed on the platform pillars in crowded platforms such as in the morning and evening rush hours, or in platform platforms where the platform itself was curved. There is provided a portable railroad wireless operation device for instructing a door closing signal operation that can display the door closing signal on a door closing signal indicator without returning to a place where the door closing signal operator is located.

  As shown in FIG. 4, the portable railway wireless operation device is portable, and in addition to the wireless microphone function, “door closing”, “confirmation”, “re-opening”, It consists of various “return” pushbutton switches and “emergency” pushbutton switches.

  As shown in FIG. 3, the various push button switches are provided with a tact switch 3 having a stem 2 on the top surface on a substrate 1, a switch guard 4 covering the tact switch 3, and the entire switch guard 4. It consists of a rubber switch cover 6 having a lower projection 5.

  The problem to be solved is that since the push button switch of the portable railway wireless operation device uses the rubber switch cover 6 for protecting the push button switch, the rubber switch cover is used over time. The point is that the return of 6 gets worse.

  The main feature of the present invention is that a flat spring is provided between the lower protrusion 5 of the rubber switch cover 6 and the switch 3 in order to improve the return of the rubber switch cover 6 for protecting the push button switch. And

The push button switch of the portable railway wireless operation device according to the present invention is provided with a flat spring between the rubber switch cover 6 and the switch, so that the return of the rubber switch cover is improved. There is an advantage that the operability of the switch is improved.
Further, the “emergency” push button switch of the portable railway wireless operation device has an advantage that it is possible to prevent an erroneous operation by providing two or more flat springs.

FIG. 1 is a cross-sectional view of the push button switch of the present invention. Example 1 FIG. 2 is an exploded view of the push button switch of the present invention. Example 1 FIG. 3 is a cross-sectional view showing a conventional push button switch. (Conventional example) FIG. 4 is an external view of a portable railway wireless operating device.

  The purpose of improving the return of the rubber switch cover 6 of the push button switch in the portable railway wireless operation device is minimized by providing a flat spring between the rubber switch cover 6 and the switch. The number of parts has improved the conventional portable wireless operating device for railways.

FIG. 1 is a cross-sectional view of an embodiment of the apparatus of the present invention, and 1 to 6 are the same as those in FIG.
A tact switch 3 having a stem 2 on the top surface is provided on the substrate 1, a flat spring guide recess 7 is formed on the top surface of the switch guard 4 covering the tact switch 3, and a flat spring 8 is mounted on the flat spring guide recess 7. Then, a rubber switch cover 6 having a lower protrusion 5 is placed thereon.
In other words, the Sara spring 8 is provided between the stem 2 on the upper surface of the tact switch 3 and the lower protrusion 5 of the rubber switch cover 6.
The exploded view is shown in FIG.
In the first embodiment, when the rubber switch cover 6 of the push button switch is pushed with a finger, the lower protrusion 5 of the rubber switch cover 6 pushes down the flat spring 8 and contacts the stem 2 on the upper surface of the tact switch 3. Is entered.
Then, the input is wirelessly output and sent to the door closing signal operating device system, and operations corresponding to the types of various switches are performed.
Thereafter, when the finger is removed from the rubber switch cover 6, the flat spring 8 returns to the upper side, pushes up the lower protrusion 5 of the rubber switch cover 6, and the rubber switch cover 6 returns better.
That is, the operability of the push button switch in the portable railway wireless operation device is improved.

  Since the main body of the present invention is the switch system mounting method, the entire door closing signal operating device system is the same as that of the prior art document 1, and the description thereof is omitted.

In the second embodiment, in the push button switch for “emergency” of the wireless operating device for a portable railway, two flat springs 8 are provided in the flat spring guide recess 7 on the upper surface of the switch guard 4 that covers the tact switch 3 of the first embodiment. This is an example of providing a sheet.
In the “emergency” push button switch of the second embodiment, since there are two Sara type springs 8, even if the “emergency” push button switch is inadvertently touched, the switch is not input. Useful for preventing malfunction.
In the second embodiment, since there are only two flat springs 8, the drawings are omitted.
This “emergency” push button switch is provided with a function of preventing erroneous operation, thereby further improving the safety of the railway wireless operation device.

  A variety of wired and wireless push button switches with a tact switch mounted on the housing and a rubber switch cover on top of them, and by providing a flat spring between them, helps to improve the operability of the push button switch and prevent malfunctions. Therefore, it can be applied to push button switches for various purposes.
