发明名称 Intrusion-secure mail box
摘要 An intrustion-secure mail box is described as being particularly suited for rural and suburban delivery. A pair of vertically offset doors are provided, through the upper of which mail intended for delivery is inserted, and through the lower of which-lockably openable by the user-the delivered mail is retrieved. A "slide" arrangement is incorporated internal of the mail box-both to direct the delivered mail inserted through the upper door towards the lower door opening, and to act as a bar to prevent an unauthorized retrieval by a person trying to gain access by a reaching through the upper door to get at mail acculumations aggregated at the area of the locked lower door.
