BACKGROUND OF THE INVENTION

The prior art offers various mail delivery indicating systems, as shown in the following U.S. Patents, but none contain the unique combination of elements and embodiments contained in this invention.
Several examples of prior art describe mail delivery indicators which are located at some distance from the mailbox itself, such as inside a house. If the person receiving mail is not inside the house, they would not be aware that mail has been delivered. Such devices would not be readily adaptable to other embodiments. U.S. Pat. No. 4,101,877 describes such a device in which current runs through wires from the mailbox to the house. If the current between the house and the unit should be interrupted for any reason, the device would not be able to function.
U.S. Pat. No. 4,999,612 also describes such a device, in which the mailbox is gravity fed. The weight of the mail triggers a signal which is sent through wires into the house. If the weight of the mail was not sufficient to trigger the signal, or if the flow of the current between the mailbox and the house was interrupted in any way, the device would not function.
U.S. Pat. No. 5,440,295 illustrates still another device in which the indicator is located inside the house, and therefore is not visible to anyone outside the house.
U.S. Pat. No. 6,114,959 describes a device which is intended for use in multiple mailbox units. The indicator is not within the mailbox itself, but within the house or apartment connected with each individual mailbox. Therefore it cannot be seen by approaching the multiple mailbox unit.
U.S. Pat. No. 5,239,305 describes a device which has been developed as a separate unit to be attached to a mailbox, not as a part of the mailbox itself, which could therefore be removed or damaged. In this unit as well, the indicator is inside the house, not in the box.
U.S. Pat. No. 5,382,945 also describes a device which has been developed as a separate unit to be attached to the mailbox rather than as a part of the mailbox itself, which therefore could be removed or damaged. It incorporates a buzzer or beeper which would not be heard unless the person approached near the mailbox. Also, the device is activated by the opening of the mailbox door, not necessarily by the delivery of mail.
U.S. Pat. No. 6,155,482 describes a device which has been developed as a kit to be installed on a mailbox. The indicator hangs down below the mailbox, making it difficult to see during the day and nearly impossible to see at night. This device and others like it which are further detailed in other examples of prior art are intended mainly for rural mailboxes, which are positioned at the side of the road, and would not be readily adaptable to other embodiments.
U.S. Pat. No. 5,335,848 describes a delivery indicator system for newspapers. It is activated by weight, and as newspapers are often quite heavy, the system possibly would not be activated by the lesser weight of ordinary mail. The indicator is a flag style device which would not be readily visible at night.
U.S. Pat. No. 5,884,838 describes a system in which an indicator rises to become visible when the mailbox is opened. This system would not work with a mailbox in which mail is deposited through a slot. The indicator would be visible for a limited distance during daylight hours, but would not be readily visible at night.
U.S. Pat. No. 7,025,250 describes a system incorporating a flag style indicator which is gravity activated utilizing the action of opening the mailbox door to trigger the indicator. This system would not work with a mailbox in which mail is deposited through a slot. The indicator could be visible during daylight hours, but would not be readily visible at night.
U.S. Pat. No. 7,066,381 describes a system incorporating a flag style indicator which extends out from the front of the mailbox, making it difficult to see from the house even during daylight hours, since such mailboxes typically face toward the street, not the house. It also would not be readily visible at night.
U.S. Pat. No. 7,083,080 describes a system in which a signal ball extends out from the side of the mailbox. In this position the indicator would be only marginally visible during the day and very difficult to see at night.
U.S. Pat. No. 6,046,675 describes another system in which a mailbox must actually be opened in order to activate the indicator. Depositing mail into the mailbox by way of a slot would not activate the unit.
U.S. Pat. No. 6,462,659 describes a system in which the indicator is not triggered by the delivery of mail but by a hand-held remote control unit. This requires that the user be in relatively close proximity to the mailbox for the indicator to work. Also, if the remote control unit were to be lost, stolen, or simply forgotten at home, the indicator could not be activated. Published Application No. 2005/0253715 describes a system which is quite similar to that which was previously cited. It also operates by using a hand-held remote control unit which requires that the user approach the mailbox fairly closely, and without the remote unit the indicator could not be activated.
U.S. Pat. No. 6,629,634 describes a system which is weight activated. Depending on the sensitivity of the system, small items might not possess enough weight to activate the system, which consists of a light. This light is only visible from the front of the mailbox, which typically faces away from the house, making it difficult to see for someone inside the house.
U.S. Pat. No. 5,385,295 describes a system in which the indicator consists of a fluorescent material which makes use of available light to activate it. The light which it creates, while visible on dim or overcast days, would not be highly visible during sunny periods when natural light is already bright, and it would not operate at night when there is an absence of natural light to activate it.
U.S. Pat. No. 5,040,723 describes a system in which a wheel on top of the mailbox is rotated by the opening of the box. Since the wheel is not large, the user would have to walk up to the mailbox to see if the wheel has been rotated. This would not be visible from a distance and would not be readily visible at night. This system would not be adaptable to mailboxes in which mail is deposited by way of a slot. U.S. Pat. No. 4,314,102 describes a system for confirming delivery of mail to a post office box. Making a telephone call is necessary to verify if mail is there.
U.S. Pat. No. 4,154,393 describes a system for securing mail inside a mailbox, but which does not indicate whether or not mail is present inside the mailbox. The system allows a person inside the dwelling to communicate with the person delivering mail, but does not make provision for recording or playing back a message.
U.S. Pat. No. 5,917,411 describes a system for securing mail inside a mailbox, but which does not indicate in any way whether or not mail has been delivered.
The above prior art illustrates various methods of alerting the user of a mail receptacle to the delivery of mail, as well as certain other adaptations which could be added to mailboxes. The present invention combines these features, along with others, which makes the system much more versatile as well as more effective. The manner by which this is realized will become apparent from a reading of the following specification, particularly when read in conjunction with the accompanying drawings.

SUMMARY OF THE INVENTION

The present invention allows the user to detect the presence of mail or messages within the mailbox without having to approach the mailbox directly, use a remote control device to activate the indicator, or be inside the building or at the location where a separate indicator is positioned. Several embodiments of this invention are possible, including but not limited to one which is intended to be suspended within a school or work locker, one which is intended to be positioned on the outside wall of a house, one which is intended to be positioned at the side of a road or street, and one which is intended to be placed on a desk or table in a home or office. Other embodiments could also be developed using this technology.
The indicating means employed by the present invention could comprise such means as one or a plurality of LED lights, or audio indicators such as a bell, chime, or spoken phrase, which would require the inclusion of an audio chip within the unit. A means to record and play back a voice message could also be included, as well as a locking mechanism to prevent mail from being removed from the mailbox by an unauthorized person once it has been deposited and a protected display window where the name and/or house number of the user could be displayed.

In this embodiment said unit is attached to the inside of said wall locker, using magnetic strips that will hold it securely in place on the metal door of said wall locker. Said magnetic strips could vary in size, depending on the size of the unit, the main requirement being that they need to be large enough to support the weight of said unit on the inside of said door of said wall locker. Other means of attachment could be used apart from or in combination with said magnetic strips. These means of attachment could include, but are not limited to, one or a plurality of suspending means attached to said unit, which would fit over one or more of the ventilation slits in said door of said wall locker. One of the advantages of said unit is that in the event a person moves from one locker to another, said unit can be moved with the rest of their belongings, since in this embodiment said unit is not attached to said wall locker with a permanent adhesive. Another advantage is that removing said unit will not damage said locker in any way, also because said unit is not attached with a permanent adhesive. One side of said unit is open, and when installed, said open side is aligned with the ventilation slits in said door of said wall locker. Anyone wishing to leave a message for the user of said wall locker can insert a card or note through one of said ventilation slits in said door. The note will then go into said wall locker, rather than falling to the floor of said locker and possibly becoming lost. Insertion of said note will activate an indicating device, allowing the user of the locker to tell that a message is there. The opposite side of said unit from said open side has a door that can be opened to allow the receiver to get his mail without removing the unit from said wall locker. Said door could be configured to slide, either up and down or sideways, or to swing open in any direction. In this way, since said unit is positioned inside said wall locker, mail cannot be accessed without opening said wall locker, making sure that no one other than the person intended to receive said message can recover it. Said unit could be constructed of transparent material, most likely but not limited to transparent plastic, either clear material or material in any of a variety of transparent colors. Said transparency of construction material would allow the user to see if he has mail without opening the unit. If desired, a non-transparent material, including but not limited to metal, wood, or plastic could be used, as would probably be the case with some of the alternative embodiments, in particular those intended to be used outside, or in locations such as a desk or table top which are more visible to people other than the user of said unit. In the preferred embodiment the shape of said unit would most likely be square or rectangular, due to space and positioning requirements, but other shapes could be used. In alternative embodiments the shape of said unit could vary more widely, for both functional and decorative purposes.
The preferred embodiment of said unit would include an electronic system that will allow the user of said wall locker to tell if he has mail without opening said wall locker, most commonly by means of a light display that will be visible through said ventilation slits in said wall locker door. In this embodiment this type of display would be preferred, in that it would not cause an undue disruption of normal activities as other types of indicators might, especially in a school environment. Said result will be accomplished by the use of one of a variety of means, including, but not limited to, a rocker arm mechanism installed in the bottom of the unit, a sensor mechanism installed in the bottom of the unit, or a system of beams traveling between the top and bottom, between the front and back, or from side to side or corner to corner within said unit. In the first method, when a note or other item is inserted into said unit, the weight of said item on said rocker arm mechanism will cause it to complete an electrical connection that activates a series of LED lights, which will show through said slits in said wall locker door. This means may or may not include a grid made of thin wire or plastic positioned over the contact area, to assure that a proper connection is made. In the second method, inserting a note or other item into said unit will block light from reaching said light sensor, activating said light display. In the third method, inserting a note or other item into said unit will interrupt the flow of said beams, activating said light display. In the preferred embodiment said light display could consist of a series of LED lights flashing in sequence, but a single light, flashing or steady, or several steady lights could also be used. A control mechanism could also be incorporated which would change the speed and/or frequency of said flashing lights. Alternative means to indicate the arrival of mail could also be used, in place of or in addition to said light display. These means could include, but are not limited to audio indicators, such as a bell, chime, music, or a voice making a statement such as “you've got mail”. These audio indicating means would require an audio chip, set up to be activated by any one of the aforementioned electronic means, either as a one time signal to indicate the arrival of mail, or set up to be repeated on a periodic basis until said mail is removed from said mailbox. Said alternative indicating means could also include a motion sensor which would detect movement when mail is deposited in said unit, thereby activating said electronic indicating means. In the preferred embodiment said electronic mechanism is shown as being battery operated, but other means of operation could conceivably be used, including but not limited to solar power. These alternative means of power would be more likely to be used in the other embodiments but could also be used in the preferred embodiment by positioning the alternative power source, such as a solar panel, on the outside of said wall locker. All forms of electronic indicating means could be equipped with an activating and deactivating mechanism, so the unit could be deactivated in the event of an extended period of inactivity, such as a vacation, which would allow battery power to be conserved in battery operated embodiments. All embodiments of said unit could also include a means which would allow a voice message to be recorded for the user of said unit. Recording of a voice message would also activate said electronic indicating means, notifying the user of the presence of said voice message. In the preferred embodiment the recording means for said voice message would be located on the outside of said wall locker, but the playback means would be located inside said locker to assure the privacy of the person for whom the voice message is intended. In other embodiments this arrangement could be altered as needed or desired.
In alternative embodiments, said unit could be adapted for home use in a variety of ways. By use of a mail delivery receptacle incorporating said electronic indicating means, the occupant of the home would be able to tell just by looking at said unit whether there is mail in it or not. This would be especially good on very cold days, very hot days, or stormy days, in that the person would not have to go outside unless there was actually mail to pick up. Said alternative embodiments could be adapted to be attached to a house, or to be set up next to the road in rural areas. Said units could also be constructed in groups, to be installed in multiple dwellings such as apartment complexes, where tenants all receive their mail in the same location. In this embodiment, said units would incorporate a small window in the front of the unit where said light display would be visible, so tenants could tell if they had mail without opening their individual box. Shapes and sizes of units used for delivery of mail by the Postal Service would be determined by United States Postal Service requirements. In said alternative embodiments, said units would not necessarily have an open side, but could incorporate a door which could slide up or down or swing in any direction, or a lid which could be raised enabling mail to be put in and taken out. It is also possible that a slot could be incorporated in the top or front of said unit for deposit of mail in addition to said door for removing mail. Said alternative embodiments could also incorporate a security mechanism, including but not limited to a latch or a locking mechanism, most notably but not necessarily a combination lock, rotary or digital, employing a series of numbers to be determined by the user of said unit. Creation and installation of said security mechanism is known to those skilled in the art.
Another alternative embodiment could be constructed as a unit which would be placed on a table or desk in either a home or office location. These units could sit on a stand, located on the desk or table, the unit itself could sit on said desk or table, or the unit could be constructed to attach to said desk or table with an attaching means, including but not limited to a hook, clamp, or clip. In this embodiment, shape does not need to be limited in any way, but said units would be designed to be decorative as well as useful. This embodiment would employ one of the said electronic indicating means to show when an item has been placed within said unit. In said alternative embodiments, said units would not necessarily have an open side, but could incorporate a door which could slide up or down or swing in any direction or a lid which could be raised enabling mail to be put in and taken out or a lid which could be raised enabling mail to be put in and taken out. It is also possible that a slot could be incorporated in the top or front of said unit for deposit of mail in addition to said door for removing mail. Said alternative embodiment could also incorporate a security mechanism, including but not limited to a locking mechanism or latch, most notably but not necessarily a combination lock, rotary or digital, employing a series of numbers to be determined by the user of said unit. Creation and installation of said security mechanism is known to those skilled in the art.
I have disclosed a useful system to enable the user of a message receptacle to detect the presence of messages, either verbal or written, without actually opening the receptacle, display the user's name and dwelling number for easier identification of the dwelling, and protect messages which have been deposited in the receptacle from unauthorized users.
While I have described and illustrated various embodiments of my invention, I wish it to be understood that I do not intend to be restricted solely to these embodiments, but I intend to cover any and all modifications thereof which would be apparent to one skilled in the art, and which come within the spirit and scope of my invention.
