BACKGROUND OF THE INVENTION
Rural mailboxes have at least a front door hinged at its bottom near the mailbox floor and many also have a rear door hinged in a similar manner at the rear of the mailbox. The fit of the door accessed by the mail carrier should not be so tight as to be difficult for the mail carrier to open and close, however a loose fit can result in moisture entering the mailbox during a wind driving rainstorm. A need exists for a mailbox door structure, which intercepts and prevents entry of moisture into a mailbox but is not difficult to open and close. Since the mailbox door is opened and closed almost daily, the rain intercepting structure should preferably not be subject to wear or other deterioration.
BRIEF DESCRIPTION OF THE INVENTION
A door and doorway of the postal compartment of a mailbox are constructed to intercept wind driven rain and route it downwardly from the mailbox, thus preventing its entry into the interior of the postal compartment. The sides and top of the door and confronting portions of the postal compartment have a registering groove and ridge construction serving to deflect and drain rain driven by wind against the door. In a plastic mailbox construction the grooves and ridges are integrally molded into the mailbox door and the postal compartment housing to form a labyrinthine structure.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 and 2 show a double walled plastic mailbox 11 having a support 12, which has two side by side pieces 13, 14 secured by screws 17 to a wooden post 16 set in the ground 18. A postal compartment 21 is mounted on top of an open ended newspaper compartment 22 and is interconnected to the newspaper compartment 22 by a floor 23 shown in FIG. 3. The newspaper compartment 22 is secured to the upper end of the support 12 by suitable fasteners, not shown.
Referring to FIGS. 3, 4 and 5, the postal compartment 21 includes a longitudinally extending housing 24 which has a double walled arched or arcuate roof 26 with an outer wall 27 and an inner wall 28 having a downwardly facing interior surface 29. The housing 24 also includes a pair of laterally spaced and longitudinally extending upright side walls or side wall structures 31, 32 which are also of double wall construction. The side wall structure 31 has a laterally outer wall 33 and a laterally inner wall 34 and, as shown in FIG. 8, the side wall structure 32 has an outer wall 36 and an inner wall 37. The inner walls 34, 37 have laterally confronting interior surfaces 38, 39 on their laterally inward sides. The inner wall 28 of the longitudinally extending arched roof 26 and the inner walls 34, 37 of the side wall structures 31, 32 form front and rear doorways 41, 42 for front and rear doors 43, 44. The doors 43, 44 each have integrally formed coaxial pivots extending outward from their laterally opposite lower ends or corners. FIGS. 6 and 7 show the pivots 46, 47 of the front door 43. The pivots extend into aligned bores or openings in the inner walls of the side wall structures 31, 32. The two openings or bores 48, 49 for the pivots of the front door 43 are shown in FIG. 5. Thus the front and rear doors 43, 44 pivot about parallel laterally extending horizontal axes.
The longitudinally opposite ends of the inner wall 28 of the roof 26 and the longitudinally opposite ends of the inner walls 34, 37 of the side wall structures 31, 32 define recesses 51, 52 with vertical shoulders 53, 54, respectively, at the longitudinally outer edges of the doorways 4142.
As shown in FIGS. 4, 6, 7 and 8, an indentation 61 is formed in the top and laterally opposite edges of the inner side of the front door 43. The indentation 61 includes a vertical surface 62 and a shoulder 63 extending from the vertical surface 62 to the inward side of the door 43. The shoulder 63 includes a recess 64 which is in juxtaposed registration with an inward extending ridge or ridge structure 66 formed adjacent the doorway 41 on the inward facing sides of inner side walls 34, 37 and on the inward facing side of the inner wall 28 of the roof. A metal plate 56 is secured by a fastener 57 to the inside of the door 43 at a notch 58 at the top of the door 43. The notch 58 creates a gap or break in the vertical surface 62 and in the shoulder 63. The metal plate 56 engages a magnet 71 in a notch 72 in the inner wall 28 of the arched roof 26. The magnet 71 releasably hods the door in a closed position.
Wind driven rain entering the clearance between the front door 43 and its doorway 41 will be intercepted and diverted by the ridge 66 to the recess 64. Rain diverted to the recess 64 passes downwardly by gravity and out the bottom ends of the recess 64 terminating at the front of the postal box floor 23. The rear door 44 and its doorway 42 are constructed in the same manner as the front door 43 and its doorway 41. Thus the interior of the postal compartment is protected from driving rain at both its front and rear doorways.
