A security mailbox comprising:
- a mailbox enclosure for housing mail deposited by a mail carrier,
- a mail holding receptacle below the mailbox enclosure, the mail holding receptacle having a lockable door, for allowing retrieval of the mail in the mail holding receptacle,
- a floor between the mailbox enclosure and the mail holding receptacle, the floor comprising two flaps extending longitudinally between the mailbox enclosure and the mail holding receptacle,
- each flap of the two flaps hingably attached along opposed inner sides of the mail holding receptacle, for pivoting movement of the two flaps, the two flaps pivoting downward to form an opening through which the mail falls into the mail holding receptacle and the flaps pivoting upward to form the floor,
- a track mounted to a lower side and along an inner edge of each said flap, each said track having a slide that is captured by the track and moving within the respective track, each said track further having a slide stop positioned at a front of the track for limiting forward movement of a respective said slide, the slide stop positioned at a predetermined point that defines initiation of opening and closing of the two flaps,
- a mailbox door pivotally attached at sides of a bottom front of the mailbox enclosure,
- a pair of downwardly depending connection bars mounted to a lower inner side of the mailbox door, one connection bar for each said flap, the connection bars extending into the mail holding receptacle and mounted to move upward within the mail holding receptacle when the mailbox door is opened and downward when the mailbox door is closed,
- a link connected between each said connection bar and a respective said slide, the link having a swivel connector at each end, for moving in swiveling relation with a respective said slide and respective said flap,
- a spring bias for biasing each said flap toward an open position so that the mail falls from the mailbox enclosure into the mail holding receptacle when the mailbox door is closed, and further biasing the mailbox door closed,
- whereby the predetermined point of the slide stop on each track defines an angle the mailbox door makes with the floor to begin to open or close the two flaps.
