Description




FIELD OF THE INVENTION




The present invention relates to rural type mailboxes and more particularly to a rural mailbox having transparent windows and doors formed on the front, sides and rear of mailbox allowing the user to view inside the mailbox with a glance without opening the mailbox thereof to check for mail.




DISCUSSION OF THE RELATED ART




It is often difficult for individuals to determine whether mail has been delivered to the mailbox and in particular rural type mailboxes, which is often positioned at the street or across the street. The user must often walk to the street or across the street and open the mailbox door and stand in front of mailbox exposing the user to dangerous traffic conditions to determine whether mail has been delivered. It would be desirable, therefore, to have a rural mailbox having a transparent windows and doors formed on the front, rear, and sides thereof so that a user could view through the windows and doors to determine whether mail has been placed inside the mailbox. A remote control that operates a light inside the mailbox would allow the user to view inside the mailbox at night. In addition, it would be desirable if the transparent window or doors were capable of sliding open to allow access to the interior of mailbox so that mail could be removed by a user safely through the windows or doors.




SUMMARY OF THE INVENTION




It is thus an object of the invention to provide a window mailbox for rural type mailboxes that includes transparent windows and doors that are capable of sliding; and a remote control that operates a light inside the mailbox that allows a user to view the interior of the mailbox to determine whether mail has been deposited or removed from the mailbox. When walking up to the mailbox, a transparent slidable window or door would provide a means of checking and retrieving mail without exposing the user to dangerous traffic conditions. The window or door would allow the user to approach the mailbox by driving up in a vehicle and retrieving or depositing mail.




Accordingly, a window mailbox is provided. The rural mailbox includes transparent windows or doors formed on the front, rear and sides thereof and can include a slide assembly to allow the window or door to slide and operate as an access door for retrieving or depositing mail when desired. A remote control transmitter could remotely illuminate the inside of the mailbox to view any mail through the windows or doors provided.

which is placed on strips of piezoelectric film


49


which are positioned at the inside bottom portion of housing


12


such that applying small amounts of force to platform


50


bends piezoelectric film


49


. The material used to form that of the lightweight platform can include metal, but is not limited to metal.




Alternatively, the flexible lightweight material platform

such that upon applying a force to platform


50


sufficient to compress springs


51




a


and


51




b


, platform


50


bends piezoelectric film


49


.




When mail (letters or packages) is placed in housing


12


, the weight of the mail applies a force to platform


50


and bends piezoelectric strip


49


, which causes a piezoelectric affect in the form of a low current spike voltage. This voltage triggers a digital voltage receiving device


42


such as a one-shot monostable multivibrator. The digital voltage receiving device


42


provides a pulse to trigger the driver circuitry to light the LED indicator


30


on the RF receiver unit

FIGS. 6A and 6B

show a window mailbox according to another aspect of the present invention. In

FIG. 6A

, opaque housing


12


comprises a second side window having a transparent panel


18


including hinges


19


to permit opening and closing the panel. However, rather than hinges


19


, the panel


18


can also be slidable as in FIG.


1


. In

FIG. 6B

, opaque housing


12


comprises a first side window


26


that is transparent.




It can be seen from the preceding description that a window mailbox has been provided.




In a preferred embodiment, a slidable or hinged door or window is provided which allows the user to access the interior of the mailbox to deposit or remove mail when desired. The mailbox has a thin lightweight sensor platform that triggers a piezoelectric sensor on the inside of the mailbox under the platform. The piezoelectric sensor signal is routed through an amplifier and buffer to provide sufficient signal strength and signal forming characteristics to the signal to convert it to digital levels (i.e., 5V—square wave).




Once the signal is transmitted from the sensor in the mailbox, it will cause a single bright light emitting diode on the top front of the mailbox to be illuminated, letting users know that mail has arrived. An internal light is turned on and off by a remote control transmitter.




An owner of the mailbox may use a remote control transmitter (similar to a car alarm remote control) to remotely illuminate the inside of the mailbox using a first button to view mail through the windows or doors at night. 6-AA rechargeable batteries may power and reside in the battery housing on the top of the mailbox to provide internal illumination. Charging of the 6—AA rechargeable batteries is provided by a flexible solar panel and charging circuit, which charges the batteries to optimum voltage levels. The charging circuit may be turned off near the battery housing by an on/off switch or remotely by a second button on the remote control transmitter. Internal mailbox illumination is provided by 4 jumbo light emitting diodes (LEDs) mounted in the inside roof of the mailbox. A power driver circuit designed to provide sufficient voltage drives these diodes and current from the rechargeable batteries to illuminate the inside of the mailbox so the user may view the mail that has arrived. The jumbo LEDs are turned on or off by the remote control transmitter at the will of the user. This is done to view the inside of the mailbox.




The remote control transmitter works in partnership with the RF receiver unit, which is mounted inside the mailbox. The receiver and transmitter are a standard receiver/transmitter pair, which is U.L. approved.




The purpose of the receiver unit is:




1) to receive and react to the signal from a first button of the transmitter to turn on and off the internal jumbo LEDs to view mail; and




2) to receive and react to the signal from a second button of the transmitter to turn on or off the battery charging circuit in the mailbox.




It is noted that the embodiment of the window mailbox described herein in detail for exemplary purposes is of course subject to many different variations in structure, design, application and methodology. Because many modifications may be made in the embodiment herein detailed in accordance with the descriptive requirements, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
