Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an emergency button cover device suitable for use in emergency notification equipment and the like.

[Prior art and its problems]

Generally, fire alarms, emergency notification systems, etc. are equipped with an emergency button, and in the event of an emergency, a notification or warning is given by pressing this emergency button. Therefore, such an emergency button must be installed so that anyone can press it quickly in the event of an emergency, and so that it cannot be easily pressed by mischief or carelessness in any other case.

For this reason, conventionally, a transparent plate-shaped plastic cover was attached to the location where the emergency button was installed to cover the emergency button, and the cover was formed so that it could be easily destroyed with finger pressure or the like.

However, these conventional plastic covers have the disadvantage that they cannot be reused once they have been used.
In particular, radio equipment used on ships equipped with a push button for sending distress signals is susceptible to the shaking of the ship, and is also equipped with a handset and various push buttons used as general communication equipment, so conventional plastic covers that can be destroyed may be mistaken. This creates the problem of easy manipulation.
Furthermore, once the cover is destroyed, it becomes difficult to repair it in terms of parts supply, etc., and there is also the problem that the emergency button cannot be protected.
