Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a push button for an emergency alarm device, and particularly to an emergency alarm push button that is provided in an intercom or the like and that sounds an alarm sound.

[Problems to be solved by conventional technology and ideas] In the event of an emergency such as a gas leak, fire, or intruder, pressing the emergency alarm pushbutton 1 installed on the intercom base unit shown in the perspective view of Figure 4 will activate the alarm. At the same time as the alarm sound is emitted, an alarm sound is also emitted from the indoor slave unit, alerting each room and neighborhood to the emergency situation.

The structure of a conventional emergency alarm push button is as shown in the cross-sectional views of FIGS. 5 and 6. In FIG. 5, a panel 3 is fitted into a housing 2, and stoppers 5 and 6 are formed integrally with the panel 3. Usually, a hogo plate 7 is inserted between a pawl 4 and a stopper 5 formed in the middle of the panel 3. is locked. When the hogo plate 7 is pushed in an emergency, the pawl 4 is pushed, and the elastic panel 3 is slightly deformed, causing the hogo plate to press the pawl 4 and the stopper 6 as shown in FIG.
button 8 is pressed. When the button 8 is pressed, the alarm device 9 is turned on and generates an alarm sound.

The emergency push button configured as above will continue to sound the alarm once it generates the alarm, so the alarm will stop generating unless the panel 3 is removed from the casing 2 and the button 8 is released from the press by the hogo board. I couldn't do it. Again, as shown in FIG. 5, there was a drawback in that it was necessary to engage the hogo plate 7 between the stopper 5 and the pawl 4 of the panel 3 to fit the panel 3 into the casing 2.

This idea was made to eliminate the above-mentioned drawbacks, and it is equipped with an emergency alarm push button that allows you to easily cancel the alarm by rotating the hogo board in the opposite direction after the emergency alarm device has sounded. The purpose is to provide.

[Means for Solving the Problems] In order to achieve the above object, the emergency alarm push button of the present invention includes a button of an emergency alarm device, a hogo board that generates an alarm by pressing the button during forward rotation, and a button for the emergency alarm device. A casing for pivoting the hogo board, and a housing provided integrally with the casing, which locks the hogo board when the hogo board rotates in the forward direction and releases the lock when the hogo board rotates in the reverse direction, thereby preventing the button from being pressed. It is characterized by having a claw for releasing it.

[Embodiment] An embodiment of the emergency alarm push button of the present invention will be described with reference to the drawings.

1 and 2 are cross-sectional views of one embodiment of the emergency alarm push button according to the present invention.
is fixed by a shaft 71. The hogo plate 70 has a concave portion 72 that is pushed to rotate in the forward direction when an emergency alarm occurs, and a corrugated portion 73 that is pushed and rotated in the reverse direction to stop the alarm. Further, a button 80, which is a switch for sounding an alarm device 90, is provided at a position that can be pressed when the hogo board 70 rotates, and a stopper 50 and a stopper 60 are provided for when the hogo board 70 rotates forward and backward. ing.

The operation of the emergency alarm push button configured as above will be explained. In the event of an emergency, when the concave portion 72 is pressed to rotate the hogo board 70 in the forward direction, the hogo board 70 rotates forward using the shaft 71 as a fulcrum, and since the housing 20 has elasticity, it is deformed at the tip of the hogo board 70. As shown in FIG.
It is locked between 0 and 0. At the same time, the button 80, which is a switch of the alarm device 90, is pressed, and the alarm device 90 makes an alarm sound.

To stop the alarm sounding, push the corrugated part 73 of the hogo plate 70, deform the housing 20 with the hogo plate 70, release the lock from the stopper 50, and rotate it in the opposite direction until it is stopped by the stopper 60. Button 80
Release the pressure and turn off the alarm device 90.

An embodiment in which the emergency alarm push button 10 described above is applied to an intercom base unit is illustrated in the perspective view of FIG. 3. The emergency alarm push button of the present invention is a simple device with a small number of parts, and the alarm can be canceled by simply operating the button.

Although an embodiment applied to an intercom base unit has been described above, the present invention is not limited to this embodiment.
It is also suitable for use in telephones and other emergency alarm devices.

[Effects of the invention] Since the emergency alarm push button of the invention has a hogo board pivoted to the housing, the alarm sound can be canceled by simply operating the button, and the number of parts is small, so it can be manufactured at low cost. Economical.
