ABSTRACT:
A mail box signal device for attachment to a rural mailbox, the invention comprises a length of flexible cord-like material mounted interiorly of the mailbox and fitting within guide structure mounted within the box. A first end of the cord-like material has a flexible flap attached thereto, the flap being retentively but releasably lodged between the door and open end edge of the mailbox. Flat signal plates attached to the opposite ends of the cord-like material are held contiguous against the underside of the mailbox when the device is a set or non-signalling position, the signal plates dropping downwardly on opening of the door of the mailbox thereby to release the flap and attached length of cord-like material. Movement of the flat signal plates to a downwardly disposed position indicates to a distant observer that the mailbox has been opened.
