In order to gain approval of the United States Postal Service a mailbox must comply with certain specifications including withstanding impact tests. A wide variety of mailboxes are being marketed including metal and plastic mailboxes. In order to minimize weight and material expense, a two wall plastic construction may be used. A brittle rigid plastic would shatter when subjected to an impact test and therefore a flexible resilient plastic is preferred. In addition to the need to pass the tests of the U.S. Postal Service, to obtain its approval, it is desirable to provide a mailbox which will withstand abuse by pranksters or vandals who may use baseball bats.
A plastic mailbox includes a double walled postal compartment, a double walled newspaper compartment beneath the postal compartment and a vertical support with a hollow interior adapted to receive an upright support post set in the ground. The top and sides of the postal compartment are formed by an inner wall and an outer wall spaced outwardly from the inner wall. The sides and bottom of the newspaper compartment are likewise defined by inner and outer walls. A partial rear wall in the newspaper compartment serves as a newspaper stop. The inner wall of the postal compartment has a ceiling part, which is reinforced by a plurality of longitudinally spaced bulges formed therein. The front portions of the postal and newspaper compartments have a stepped construction producing a forwardly projection rim.
One embodiment of the invention is illustrated in the accompanying drawings, in which:
The plastic mailbox 11 illustrated in
Referring to FIGS. 3 though 8 the postal compartment 12 has a longitudinally extending double walled arched roof structure 43 and double wall side wall structures 46, 47 formed by an outer wall 41 and on the inner wall 42. The outer and inner walls 41, 42 each have laterally spaced upright segments and an arched segment between the upper ends of the upright segments. An arched ceiling 48 segment of the inner wall 42 has a pair of longitudinally extending parallel rows of upwardly extending and spaced pockets or bulges 51, 52 forming longitudinally extending parallel rows of equally spaced pockets 53, 54. The upwardly extending pockets 51, 52 provide rigidity and strength to the ceiling segment 48 of the inner wall 42 and thus afford resistance to downward deflection of the roof structure 43 of the postal compartment 18 should it happen to be impacted.
The postal compartment 12 and the newspaper compartment 13 are strengthened at their front ends by formation of a shoulder 61 at the forward end of the outer wall 41 of the postal compartment housing 18 and by formation of a shoulder 62 at the front end of the newspaper compartment 13. The shoulders 61, 62 define a forwardly projecting reinforcing lip 64 encircling the front of the postal and newspaper compartments 12, 13. The lip 64 projects forwardly from the top and side wall structures 43, 46, 47 of the postal compartment 12 and projects forwardly from the side and bottom wall structures 26, 27, 28 of the newspaper compartment 13 thereby circumscribing the front of the mailbox 11.
