## Background
FIELD OF THE DISCLOSURE
The disclosures made herein relate generally to postal mailboxes and, more particularly, to postal mailboxes configured for enhancing visual inspection and containment of mail.
BACKGROUND
Postal mailboxes (i.e., mailboxes) of various types and configurations are well known. The underlying intent of such mailboxes is enabling mail to be conveniently and securely delivered and contained within the mailbox. To this end, conventional mailboxes include any number of functionalities that are intended to enhance the manner in which such delivery and containment of mail is accomplished.
Dual door mailboxes, which are well known, are one example of mailboxes that include functionality that is intended to enhance the manner in which delivery and containment of mail is accomplished. Such mailboxes have a first door at a first end and a second door at a second end. In regions utilizing mailboxes located adjacent to an edge of a roadway, a mail recipient having the dual door mailbox does not have to leave enter the roadway or shoulder area of the roadway to either place outgoing mail into or retrieve delivered mail from the mailbox. To make best use of such a dual door mailbox, the mailbox is mounted such that the first door is adjacent the roadway, thereby enabling a mail carrier to conveniently deposit mail into an interior space of the mailbox either while in a mail delivery vehicle. In such a mounted orientation, the second door faces away from the roadway. Accordingly, the mail recipient simply opens the second door to gain access to an interior space of the mailbox, allowing them to remain at a relatively safe distance from the roadway.
While such conventional dual-door mailboxes clearly offer advantages from a safety standpoint, they are not without shortcomings. One shortcoming is that, in the event that both doors of a dual-door mailbox are fully or partially open at the same time, wind may blow mail out of the mailbox because the floor is essentially level with the bottom edge of each door. Another shortcoming is the expense and complexity associated with implementing a means for ensuring that only one door is open at a time and/or ensuring that the doors are normally biased to a closed position. Still another shortcoming is that, because the floor of a conventional dual door mailbox is essentially level with the bottom of the doors, the volume of the mailbox is limited to a space above the bottom edge of the doors.
Mailboxes with one or more see-through windows in the mailbox body or a door of the mailbox or with one or more see-through walls are well known in the art and are another example of mailboxes that include functionality that is intended to enhance the manner in which delivery and containment of mail is accomplished. The intent of the one or more see-through windows or walls is to allow contents of the mailbox to be viewed prior to opening or otherwise disturbing the mailbox. As mentioned above with respect to dual door mailboxes, a shortcoming of single-door or dual-door mailboxes is that, because the floor of a conventional single-door or dual-door mailbox is essentially level with the bottom of the door or doors, the volume of the mailbox is limited to a space above the bottom edge of the door or doors. A related shortcoming is that overall visibility of relatively objects being viewed through the one or more see-through windows or walls is adversely impacted because of the relative vertical position of the one or more see-through windows with respect to a package resting on the floor of the mailbox. Inherently, for relatively large and/or tall packages, a relatively limited view of upper portion of the packages through the one or more see-through windows is often exhibited.
Therefore, a postal mailbox that that overcomes shortcomings associated with conventional postal mailboxes would be useful and advantageous.
SUMMARY OF THE DISCLOSURE

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 depicts an embodiment of a mailbox in accordance with the present invention.
FIG. 2 is a cross-sectional view taken along the line 2-2 in FIG. 1.



DETAILED DESCRIPTION OF THE DRAWING FIGURES
FIGS. 1 and 2 depict an embodiment of a mailbox in accordance with the present invention, which is referred to herein as the mailbox 10. The mailbox 10 includes a mailbox body 12, a first door 14 and a second door 16. The mailbox body 12 has a first access opening 18 and a second access opening 20. As depicted, the two access openings (18, 20) are opposed with respect to each other. An interior space 22 (best shown in FIG. 2) extends between the first access opening 18 and the second access opening 20.
The interior space 22 includes a cavity 24 extending below a bottom edge 26 of the access openings (18, 20) and a main portion 28 above the cavity 24. Advantageously, the cavity 24 provides for a recessed portion of the mailbox body 12 in which mail is captured. Because the mail is captured in the cavity 24, much better protection against the mail being accidentally blown out of the mailbox 10, such as in the case where both doors (14, 16) are accidentally left open.
The cavity 24 is defined by opposed side walls 30, opposed end walls 32 and a bottom wall 34. The opposed side walls 30 and the opposed end walls 32 define respective side faces of the cavity 24. Preferably, as depicted, the opposed side walls 30, the opposed end walls 32 and the bottom wall 34 are generally flat and interconnected in a manner such that the cavity has a rectangular-shaped volume. The opposed side walls 30 each extend upward from adjacent the cavity 24 and are curved toward each other to form an arch shaped top surface 36. Optionally, the opposed side walls 32 may be terminate into a flat or curved top wall. The opposed end walls 32 each terminate into a respective ledge 38 such that each end face 32 of the cavity 24 is recessed with respect to the access opening (18, 20). The cavity 24 preferably, but not necessarily, has a width essentially the same as a maximum width of the interior space 22.
The first door 14 is pivotally attached to the mailbox body 12 adjacent the first access opening 18. The first door 14 is pivotable between a first respective position covering effectively an entire portion of the first access opening 18 (i.e., a closed position C1) and a second respective position enabling access to the interior space 22 through the first access opening 18 (i.e., a respective open position O1). The second door 16 is pivotally attached to the mailbox body 12 adjacent a second access opening 20. The second door 16 is pivotable between a first respective position covering effectively an entire portion of the second access opening 20 (i.e., a closed position C2) and a second respective position enabling access to the interior space 22 through the second access opening 20 (i.e., a respective open position O2). Each door (14, 16) includes a handle 37 that engages a mating retention member 39 when each door (14, 16) is in a respective closed position.
Each door (14, 16) has a window opening 40 therein and a see-through window 42 covering the window opening 40. Each opposed side wall 30 of the cavity 24 has a window opening 44 therein and a see-through window 46 covering the window opening 44. Each opposed end wall 32 of the cavity 24 has a window opening 48 therein and a see-through window 50 covering the window opening 48. Advantageously, the see-through windows (42, 46, 50) enable a substantial portion, if not an entire portion, of the contents of the mailbox 10 to be viewed without opening the doors (14, 16) of the mailbox 10. It is disclosed herein that a single see-through window may be provided in only one of the doors and/or only one of the walls defining the cavity 24.
In the preceding detailed description, reference has been made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the present invention may be practiced. These embodiments, and certain variants thereof, have been described in sufficient detail to enable those skilled in the art to practice embodiments of the present invention. It is to be understood that other suitable embodiments may be utilized and that logical, mechanical, chemical and electrical changes may be made without departing from the spirit or scope of such inventive disclosures. To avoid unnecessary detail, the description omits certain information known to those skilled in the art. The preceding detailed description is, therefore, not intended to be limited to the specific forms set forth herein, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents, as can be reasonably included within the spirit and scope of the appended claims.
