Outdoor mailboxes have been around for many years, and come in many sizes and shapes, and are exposed to all types of weather conditions. Popular types of mailboxes include an elongated compartment such as a rectangular housing with a flat roof or curved roof, and an access door that swings open, where the door must be able to close and remain closed, especially for protection from outside elements. Being exposed to varying outdoor weather conditions means that moisture and water of varying degrees are likely to enter into the boxes even with the door being closed. The water/moisture entry problem is further compounded during severe weather conditions, such as but not limited to rainstorms, snow storms, and the like.
Some mailboxes have doors that can partially but weakly seal the open end of the mail box by closing under a cowling to abut against an internal face, or “rain guard” lip. With such designs, it is common for water entering a mailbox with a conventional rainguard will tend to disperse or splatter the interior of the mailbox to varying degrees depending upon the severity of the external weather conditions. Water can pass into the mailbox during blowing rainstorms, where the internal lip edge does not block or control the water entering into the box. Current mailboxes also do not allow for water entering the interior to be controlled and released from the boxes. Instead splatter and puddles form inside of the mailboxes. Thus, mail type contents inside become damaged by being exposed to weather elements, where paper and cardboard items may become irreparably damaged.
Other types of mailboxes have exterior doors that wraps about an open end of a mailbox. Similarly, rainwater and the like, can easily be driven between a wrapped door edges into the mailbox. Also, these current mailboxes also do not allow for trapped water to be released from the boxes and instead become puddles inside of the mailboxes. Thus, mail type contents inside become damaged by being exposed to weather elements, where paper and cardboard items become irreparably damaged.
Still furthermore, these current mailbox doors will often fail to stay shut during rainstorms. An open mailbox is clearly prone to water intrusion that damages mail type contents. Failure to secure the mailbox door in a closed position will allow for the mailbox contents to become dislodged and lost, and even stolen overtime.
Still furthermore, mailboxes that allow for water intrusion have a reduced lifespan since the inside moisture and water can further more quickly deteriorate the box, by oxidation, rust, and the like.
Adding extra sealing materials such as weather stripping and the like, would be generally impractical. The cost of adding weather stripping and the like, with or without extra fasteners, can substantially raise the cost of inexpensive mailboxes making them impractical to be manufactured and sold. Still furthermore, weather stripping such as rubber and elastomeric material, would not last long due to extreme environmental conditions. For example, heat can act quickly and harshly, on seals and gaskets causing the materials to dry up, rot, and disintegrate. Self-stick adhesive materials can similarly dry out as well. Any added on material would also be prone to separate, peel, and/or fall off the box. Additionally, adding weather stripping by mechanical fasteners can further create manufacturing concerns that detract from the mailbox. Adding extra materials can potentially create snag hazards for clothes, in addition to possibly creating sharp edges that can scratch and puncture persons using the mailbox.

The door 20 can be closed by moving the handle 50 with the door 20 backward in the direction of arrow O, so that magnet 155 on a door mount flange on mailbox front end roof 150, is close enough to attract an upper metal interior surface portion of the metal door 20 which keeps the door 20 in a closed position.
The floor 39 of the mailbox 1 can have parallel longitudinal indentations 38 that can slope forward to enhance any drainage of water and moisture that may get into the mailbox 1, if and when the door 20 is opened during rainstorms, and other wet conditions, and the like. The floor can be horizontal or partially sloped or tilted to the open end of the mailbox to enhance drainage effects if water gets inside.

The drainage grooves 100 can further include an upper left roof curved channel groove 120 and an upper right curved channel groove 130 both positioned inside the front of roof 34 of the mailbox 1. The upper left and right roof curved channel grooves 120, 130 can be formed from bent metal flanges 124, 134 that attach to the flat C-shaped longitudinal base plate/band 104 forming a U-shaped groove therebetween. A space can exist between the upper left curved channel groove 102 and the upper right curved channel groove 130 to allow for the magnet 155 and mount 150.
The drainage grooves 100 can further include a right side channel groove 140 positioned inside the front of right side wall 36 of mailbox 1. The right side channel groove 140 can be formed from a bent metal flange 144 that attaches to the flat C-shaped longitudinal base plate/band 104, forming a U-shaped groove therebetween.
The channel grooves 110, 120, 130, and 140 can be attached inside the front end 10 of mailbox 1, by welding the flat C-shaped longitudinal base plate/band 104 to the inside of the mailbox 1. Alternatively, the base plate 104 can be attached by fasteners such as but not limited to rivets, screws, and the like.
As described, the channel grooves 110, 120, 130, and 140 can have U-cross-sectional shapes, with groove widths of approximately 0.205 inches to allow for water drainage in that space, with the wall thickness of the metal being approximately 0.024 inches thick, and the depth of the grooves 110, 120, 130 and 140 can be approximately 0.551 inches. The bent metal flanges 114, 124, 134 and 144 can extend outward approximately 0.157 inches from the flat C-shaped longitudinal base plate/band 104.

The size of the inwardly angled door edges 22, 24 and 26 allow for a snug fit into the channel grooves 110, 120, 130 and 140, so that any moisture or water being driven toward the front closed front door 20 can become trapped outside of the chamber 30 and only drain by gravity downward to escape out the drain openings that are formed underneath the left and right channel grooves 110, and 140 that extend in front of the floor 38 of the mailbox 1. Additionally, other through-holes can be formed in the floor 38 to allow for additional drainage.
Alternatively, the angled door edges 22, 24 and 26 of the door 20 can have a slightly loose fit, which still allows for drainage since moisture and water would still run down the channel grooves 110-140 by gravity.
Still furthermore, an optional weather strip or silicon seal, and the like, 190, such as but not limited to rubber type gasket, elastomeric and the like, can be inserted into some or all of the channel grooves to also enhance the waterproof seal between the outside of the door and the inside of the main chamber 30. Additionally, the weather stripping could provide both sound and impact vibration dampening effects when the door is closed.
The preceding embodiment generally describes the invention with doors that fit into the open ends of the mailbox chamber to rest in a closed position underneath a protective overhang portion. The invention can also work with mailboxes that have doors with edges that wrap about the outer opening end of the mailbox itself.

In this other embodiment, the door 220 can be sized to fit about and wrap around the exposed end 210 of the mailbox 200. Door 220 can include a left side inwardly protruding door edge 222A, curved roof inwardly protruding door edge 224A, and right side inwardly protruding door edge 226A, each of which can fit into the respective channel grooves 310, 320 and 330 of the main chamber 330, and function similarly to that of the preceding embodiment figures.
In this embodiment, the door 220 can include a parallel set of outer left side inwardly protruding door edge 222B, an outer curved roof inwardly protruding door edge 224B, and an outer right side inwardly protruding door edge 226B. The outer edges 222B, 224B and 226B can wrap about the open end of the mailbox 200. As shown in
Although the embodiments show the channel grooves being attached in place, the channel grooves can be molded or stampled or bent from existing ends of the main chamber.
While the channel grooves are part of the same material of the mailbox, the channel grooves can be a separate flange material that is attached in place, having the example, an L cross-sectional shape.
While the embodiments show a single door on the mailbox, the mailbox can include both a front and a rear door, with both ends of the mailbox having the novel channel groove drainage features.
While the embodiments show the channel about the open end of the mailbox, the channel can be part of the inside edges of the door(s) to the mailbox.
The invention can also be retrofitted into existing mailboxes and/or made to be part of newly manufactured mailboxes.
While the invention has been described, disclosed, illustrated and shown in various terms of certain embodiments or modifications which it has presumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they will fall within the breadth and scope of the claims here appended.
