ABSTRACT:
A mailbox for receiving delivered mail includes a housing and a post for mounting the box to the ground. A door is connected to a shaft rotatably secured to the bottom edge of a door opening, and the door extends beyond the opening into a tail portion. A part of the housing floor is formed from a resilient material so that the door is normally stopped thereby upon opening. Should the door be forced further, the material will yield to allow the door to swing below the box to prevent damage. A security latch, hidden beneath the housing, includes a leaf spring normally positioned behind the door tail portion to prevent its opening. The spring may be moved into a slot in the door shaft, where the spring cooperates with a notch in the door to permit its opening. Upon closing of the door, the spring is released to its normal position, whereupon the door is again held shut. The flag target is carried at the end of a flag shaft that is rotatably and slidably secured to the housing interior. A spring connects the shaft to the rear wall of the housing. The flag is extended by pulling the target and shaft from the box and rotating the target to engage the wall of the box, and is returned by rotating the target to allow the spring to retract the flag into the box. An energy absorbing mount for the post includes a resilient member secured by a single bolt between two plates, one plate in turn attached to the post and the other being secured to the ground.
