ABSTRACT:
A door intercom device for allowing a dwelling occupant to easily converse with an individual disposed on an exterior side of a dwelling door includes a thin sheet metal mounting bracket possessing a generally U-shaped clamp portion dimensioned to engage over the top edge of a conventional swinging door. An elongated interior portion of the bracket includes a terminal end portion upon which a master station of a two-station intercom system is mounted. A suction cup on a rear face of the terminal end portion of the mounting bracket secures the device in place on the interior face of a door. A second station of the intercom system is secured on a short leg portion of the U-shaped clamp, on an exterior face of the door. Electrical wiring connecting the intercom stations extends along the rear face of the mounting bracket, protected within an overfolded bead portion. The door intercom device may be easily installed on a conventional door in a matter of seconds, without the need for any modification to the door or dwelling structure, and without the use of any tools.
