FIELD OF THE INVENTION
The present invention relates to mailbox systems that are resistant to damage. The systems are especially resistant to heavy snow and slush projections from snowplows. USARMOURBOX™ is a trademark represented by trademark U.S. Pat. No. 86,932,044 filed Mar. 8, 2016.
BACKGROUND OF THE INVENTION
In areas where curb side mail delivery is required, such as townships and unincorporated resident and business mailboxes, with road speed limits exceeding 25 mph, snow plow trucks have enough speed to push snow off the road to create airborne snow loads causing severe damage to standard mailboxes and mounting posts.
The present invention has a unique structural design and incorporates United States mail design standards in function and size limitations.
Prior to the invention, mailboxes did not utilize an architectural form and structural theory to protect the mailboxes from destructive elements such as snow plow roadway work.
Although there are prior mailboxes that utilize a static aerodynamic design to protect said mailboxes from destructive elements, such as weather and flying projectiles, the USARMOURBOX™ system employs a dynamic feature which allows change in shape according to settings to accommodate seasonal road maintenance of snow plow snow removal.
SUMMARY OF THE INVENTION
The present invention is “virtually indestructible”. The mailbox incorporates typical architectural geometric shapes formed with aluminum sheet metal for armour type strength. The design protects the mailbox from snow loads projected from snow plows when the invention is transformed by rotation of the mailbox to face into the direction of destructible forces from snow plows. The invention has two designs which make it unique. Pivotal components adjust for winter destructive mode. In summer, other destructive objects result from roadside unpredictable objects. Illustrated figures represent the unique secondary mail hatch opening. This end section of the round box has the same function as incorporated on traditional mailbox hatch openings.
The present invention's unique structural shape consists of i) an circular amour round tube shape and ii) a “bullet” shaped horizontal design. These are structurally incorporated into shape with a dome structure.
The architectural portion of a half sphere, dome shape, is so constructed as to exert an equal thrust in all directions. The mail vault, vault structure, dome, and architectural shape provide unity between the dwelling unit with said mailbox utilitarian form follows function theory.
The transformed traditional box shape with barrel vault top to shed snow and water into a circular tube extruding the backside into a dome shape. In architectural theory, the practice of utilizing a geometric shape is to disperse applied loads in the horizontal forces associated with forces of a road side snow plow removing snow from roadways.
In another preferred embodiment, a unique mailbox post allows the mailbox to be rotated and locked into a place in its “winter” mode, so that the dome shaped end is directed towards the snow and slush from snow plows.

DETAILED DESCRIPTION OF THE INVENTION
The employment of given certain geometric forms used to resist structural forces can be found in circular forms of plutonic shapes such as the incorporated hollowed metal half sphere dome.
Referring to drawings, FIG. 1 illustrates the blast force resistive shape designed to virtually resist snow plow blast with the “indestructible” mailbox referred to in the Figs.
The present is directed to an ‘indestructible’ mailbox which has a dome shaped end directed toward destructive snow plow road work, anti-destructive armour shape is to deflect any oncoming impact forces and to absorb said forces into the circular shaped body.
The bullet-like shape is a vault, having a circular plan and usually in the form of a portion of a sphere, so constructed as to exert an equal thrust in all directions.
LIST OF COMPONENTS
1. Mailbox shell main body round tube shape rolled aluminum plate with one continuous welded seam located underneath main body.
2. Geometric dome end, stamped diamond aluminum plate or construction options such as in incorporated into aircraft nose cone of spun aluminum into shape to absorb blunt impact force from roadside snow plow snow removal at speeds greater than 25 mph known to damage traditional mailbox shapes. The structural force directions implied from impact which said shape will distribute loads into adjacent tube geometric form. If required, will be locations of additional truss like ribs to provide the required additional structural requirements to absorb impact loads.
3. Winter or expected snow removal is shown with side hatch rotated to be the front hatch for roadside mail delivery access. Section of round tube extracted and offset with friction water tight flanges, closing and opening latch sized in length will be determined on force resistant requirements for impact testing. Attached to the main body by 14 a nautical boat hatch type hinge to assist in water tightness closure.
