## Title
Mailbox

## Abstract

A mailbox has four sides generally forming a triangular enclosure to deflect snow thrown by the snowplow.

## Background
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the general art of mailboxes, and to the particular field of mailboxes that are resistant to external damage.
BACKGROUND OF THE INVENTION
In rural areas, it is common for mailboxes to be mounted on posts at the roadside. In many instances, a mail box may be damaged or broken off due to impact from the snow from the snowplow, and other foreign objects such as ice, dirt, stone, etc. Therefore, there is a need for a mailbox that can deflect the snow thrown by the snowplow to minimize the damage on the mailbox.
SUMMARY OF THE INVENTION
The above-discussed disadvantages of the prior art are overcome by a mailbox having bottom that can deflect snow thrown by the snowplow such as a V-shape or concave bottom. The bottom of the mailbox is configured to minimize the impact from snow thrown upwards by a snowplow to minimize damage on the mailbox. In one example, the mailbox may generally have a tetrahedron shape that can be generally defined as having four triangular plates, three of which meet at their respective vertex.
Other systems, methods, features, and advantages of the invention will be, or will become, apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the invention, and be protected by the following claims.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1A-1D shows a mailbox 10 that resists damage due to snow, ice and the like being thrown up towards the mailbox 10 by a snowplow and the like. FIG. 1B shows the mailbox 10 having a first plate 12, a second plate 14, a third plate 16, and a fourth plate 18. Each of the four plates may have a triangular outer configuration. The first, second, and third plates may have a first base 13, a second base 15, and a third base 17, respectively; and first tip 19, a second tip 21, and a third tip 23, respectively. The first, second, and third tips are distal from their respective first, second, and third bases.
The first, second, and third plates may be joined together so that the first, second, and third tips 19, 21, and 23 are joined together to form a common tip 20, which is distal from the three bases 13, 15, and 17. The common tip 20 may be rounded. The second and third plates 14 and 16 may have a substantially similar outer triangular shape joined together at a seam-line 22. The second and third plates 14 and 16 may be adapted to receive one end of a post 24 along the seam-line 22 when the mailbox 10 is in use. The first plate 12 may be joined to the second and third plates 14 and 16 along the seam-lines 26 and 28, respectively. The first plate 12 may have an opening 30 adapted to receive one or more mails. The outer edges of the fourth plate 18 may be coupled to the bases 13, 15, and 17. The fourth plate may have a door 32 that opens and closes to retrieve the mail in the mailbox 10. As described above, the four plates 12, 14, 16, and 18 may form a mailbox 10 having a triangular enclosure.
FIG. 1C shows the side view of the mailbox 10. The first plate 12 may be orientated to have an acute angle θ1 relative to a vertical axis 34 when the mailbox is in use such that the first plate 12 is facing towards the common tip 20. This makes it easier to insert a mail into the opening 30 of the first plate 12; and any water from rain or from sprinkler system will tend to roll off the first plate 12 rather than resting on the first plate 12. The seam-line 22 may also form an acute angle θ2 relative to a vertical axis 34 when the mailbox is in use. As such, any water that enters the mailbox 10 may flow towards the bottom corner 38. The bottom corner 38 may have an outlet opening 40 to drain the water that enters the mailbox 10 so that mails do not get wet.
FIG. 1D shows a cross-sectional view of the mailbox 10 along the line 1D-1D of FIG. 1C. The cross-section generally shows a triangular formation with a space 36 inside for one or more mailers. FIG. 1D shows the inner surface of the fourth plate 18 having the door 32 that can open and close to retrieve the mailer inside the mailbox 10. The second and third plates 14 and 16 may be substantially flat surfaces forming a V-shape bottom when the mailbox 10 is in use. As such, snow thrown towards the bottom of the mailbox 10 can be deflected to minimize the direct impact on the mailbox, thereby minimizing the potential damage the snow can have on the mailbox 10.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of this invention. For instance, FIGS. 2A and 2B show that the first plate 12′ may be substantially flat and horizontal when in use. FIGS. 3A and 3B show that the first plate 12′′ may be semi-circular. FIG. 4 show that the second and third plates 14′ and 16′ may be concaved. FIG. 5 show that the fourth plate 18′ may be substantially flat and orientated to have an acute angle θ3 relative to the vertical axis 34. This allows the door 32 to remained opened once it is opened. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents.
