A mailbox characterized by a box provided with a hinged door, and a pair of indicator flags pivotally attached to opposing sides of the box. The indicator flags are spring loaded such that one of the flags is biased towards an upright position, and the other flag is biased towards a horizontal position. Spring loaded links are attached to each of the flags to engage a pair of studs provided on opposing sides of the mailbox door. The links are adapted to hold the flags until the door is opened, at which time the flags will rotate to their biased positions.

1. A mailbox apparatus comprising: an elongated enclosure provided with an opening through which mail may be inserted and removed; a door hinged to said enclosure to selectively cover and uncover said opening, said door being closed when said opening is substantially covered and opened when said opening is substantially unobstructed; a first elongated indicator flag pivotally attached to a first side portion of said enclosure, said first indicator flag being pivotable between a non-vertical position and a substantially vertical position; means biasing said first indicator flag towards said substantially vertical position; a stop attached to said first side portion of said enclosure to prevent said first indicator flag from rotating past said substantially vertical position; means for retaining said first indicator flag in said non-vertical position when said door is closed including a first stud attached to said door, a first link pivotally attached to said first indicator flag and engagable with said first stud, a stop attached to said first indicator flag to limit the rotation of said first link, and means biasing said first link towards said stop, said first link being a substantially straight, elongated member pivotally attached at one end to said first indicator flag such that its other end may engage a lower surface of said first stud when said door is closed; a second elongated indicator flag pivotally attached to a second side portion of said enclosure, said second indicator flag being pivotable between a non-vertical position and a substantially vertical position; and means biasing said second indicator flag towards said non vertical position, and means for retaining said second indicator flag in said vertical position when said door is closed; whereby the opening of said door causes said first indicator flag to pivot to said substantially vertical position and said second indicator flag to pivot to said substantially non-vertical position. 2. 2. A mailbox apparatus as recited in claim 1 further including a stop attached to said second side portion of said enclosure to prevent said second indicator flag from rotating past said non-vertical position. 2. A mailbox apparatus as recited in claim 1 further including a stop attached to said second side portion of said enclosure to prevent said second indicator flag from rotating past said non-vertical position. 3. A mailbox apparatus comprising: an elongated enclosure provided with an opening through which mail may be inserted and removed; a door hinged to said enclosure to selectively cover and uncover said opening, said door being closed when said opening is substantially covered and opened when said opening is substantially unobstructed; a first elongated indicator flag pivotally attached to a first side portion of said enclosure, said first indicator flag being pivotable between a non-vertical position and a substantially vertical position; means biasing said first indicator flag towards said substantially vertical position, and means for retaining said first indicator flag in said non-vertical position when said door is closed; a second elongaged indicator flag pivotally attached to a second side portion of said enclosure, said second indicator flag being pivotable between a non-vertical position and a substantially vertical position; means biasing said second indicator flag towards said non-vertical position, and means for retaining said second indicator flag in said vertical position when said door is closed including a second stud attached to said door, and a second link pivotally coupled to said second indicator flag and engagable with said second stud; and a stop attached to said second side portion of said enclosure to prevent said second indicator flag from rotating past said non-vertical position; whereby the opening of said door causes said first indicator flag to pivot to said substantially vertical position and said second indicator flag to pivot to said substantially non-vertical position. 4. A mailbox apparatus as recited in claim 3 wherein said means for retaining said second indicator flag in said vertical position further includes an arm extending from said second indicator flag, and pivot means attaching said second link to said said arm. 5. A mailbox apparatus as recited in claim 4 wherein said means for retaining said second indicator flag further includes a stop attached to said arm to limit the rotation of said second link, and means for biasing said second link against said stop. 6. A mailbox apparatus as recited in claim 5 wherein said second link is a substantially L shaped member having one leg pivotally attached to said arm such that its other end may engage a lower surface of said second stud when said door is closed. 7. A mailbox apparatus comprising: an elongated enclosure provided with an opening through which mail may be inserted and removed; a door hinged to said enclosure to selectively cover and uncover said opening, said door being closed when said opening is substantially covered and opened when said opening is substantially unobstructed; a first elongated indicator flag pivotally attached to a first side portion of said enclosure, said first indicator flag being pivotable between a non-vertical position and a substantially vertical position; a stop attached to said first side portion of said enclosure to prevent said first indicator flag from rotating past said substantially vertical position; means biasing said first indicator flag towards said substantially vertical position; means for retaining said first indicator flag in said non-vertical position when said door is closed including a first stud attached to said door, a first link pivotally attached to said first indicator flag and engagable with said first stud, a stop attached to said first indicator flag to limit the rotation of said first link, and means biasing said first link towards said stop attached to said first indicator flag; a second elongated indicator flag pivotally attached to a second side portion of said enclosure, said second indicator flag being pivotable between a non-vertical position and a substantially vertical position; means biasing said second indicator flag towards said non-vertical position; and means for retaining said second indicator flag in said vertical position when said door is closed, including a second stud attached to said door, and a second link pivotally coupled to said second indicator flag and engagable with said second stud; whereby the opening of said door causes said first indicator flag to pivot to said substantially vertical position and said second indicator flag to pivot to said substantially non-vertical position.
