## Background
FIELD OF THE INVENTION
The invention pertains to improvements in mailboxes, and more particularly to an improved mail indicator that notifies the mail recipient when the daily mail has been delivered and deposited into a mailbox.
BACKGROUND OF THE INVENTION
One of the most ubiquitous activities in every day life, is the delivery and retrieval of the daily mail. Most individuals look forward to receiving their daily mail, and often eagerly await the arrival of the mail courier. In rural areas, the mailbox often stands along the roadway, adjacent the homeowner's property. The mailbox is usually fitted with a flag to indicate to the courier, that there are posted letters inside the box. The flag is raised above the box, when the homeowner deposits the posted mail for pick-up. Upon retrieving the posted letters, and delivering the daily mail, the courier pushes the flag back to its neutral, horizontal position. This indicates to the homeowner, that the posted letters have been taken from the box, and that newly arrived mail is present.
On those occasions where the mail recipient has no letters to post, the arrival of the daily mail is non-indicated. Unless the property owner actually catches the exact moment of arrival of the courier, there is absolutely no way to determine that new mail has arrived.
It has occurred to many homeowners, that it would be most advantageous to have a signaling, or indicating device attached to the box, in order to be apprised of the delivery of the daily mail.
Many such devices have been conceived and patented. One of the many drawbacks of past and present mail indicators, is their complexity, unreliability, and their limited line of sight.
In U.S. Pat. No. 627,635; issued to F. C. Bates, for a Postal Box Signal, issued on: Jun. 27, 1899, a mailbox is illustrated having two signal flags. The first flag is used to indicate that posted mail has been taken, and the second flag is displayed in the event that new mail has been deposited. The problem with a two flag system, is the confusion often created between the meaning of the two flag signals. Should there be only one flag standing, does that indicate the retrieval of posted mail, or the delivery of the daily mail? This invention claims to differentiate the flags by color, but at a distance, such distinguishing features can be difficult to discern. In addition, this inventive device has complicated linkage that can be operatively unreliable.
In U.S. Pat. No. 3,648,924; issued to: Burns, on Mar. 14, 1972, for a Mailbox Signal, a two flag mail indicator is shown. The first flag is the traditional flag for posted mail. The second flag indicates the delivery of mail. The second flag is caused to rotate downwardly about a journal pin, when the mailbox door is opened. The problem with this indicator, is that it is difficult to see the second flag, when it swings below the mailbox.
In U.S. Pat. Nos. 3,589,329 and 4,589,329; issued to Schuh and Malik, respectively. Both of these mail indicators feature chain-tethered flags that assume an erect position, when the mailbox door is opened. The problem with chain-tethering is the possibility of linkage entanglement, kinking, and linkage failure.
In U.S. Pat. No. 5,076,337 issued to Reuter on Dec. 31, 1991, for a Mail Arrival Alert for Mailbox, a spring-loaded flag is caused to assume an erect position upon opening of the mailbox. The problem with this system, is that it can be confused with the pop-up flag for posted mail, and spring assisted devices can take a set, or snap. Similar devices are shown in U.S. Pat. Nos. 5,964,401 and 6,575,357 B1.
In U.S. Pat. No. 5,428,206 issued on Jan. 9, 1996 to Waycasy for: Automatic Mail Delivery Signaling Device, a flag is caused to assume an erect position with the opening of the mailbox door. A trigger arm and lever are utilized to provide the flag movement.
In U.S. Pat. No. 4,491,268; issued to Faulkingham on Jan. 1, 1985, for a Mailbox Delivery Signal Device, a brightly colored, spring-loaded, indicator arm is caused to pop-up upon release of the mailbox latch, thus signaling the daily mail delivery.
In U.S. Pat. No. 6,659,357B1, issued to Woelfel, on Dec. 9, 2003, for a Universal Mailbox Flip-flag Indicator, a detachable flag is disposed in the mailbox door. The detachable flag flips into view, when mail is delivered.
It is evident from the vast display of prior art, that what is needed for a mailbox mail delivery-signaling device, is a simple, reliable, and easily discernible indicator.
The present invention provides a simple pivoting rod, that is pivotally attached above the mailbox in proximity to the latched opening. The rod pivots from an upright position, to a benign, horizontal position upon the unlatching of a mailbox door. The very simplicity of the current inventive device will reduce cost, require less parts, and provide reliability. The pivoting rod is decidedly distinct from mail flag indicators, thus eliminating confusion with posted mail indication.
SUMMARY OF THE INVENTION
The invention features a mailbox indicator for determining when the daily mail courier has deposited mail in a rural or suburban mailbox. The mailbox indicator features a pivotal rod, which is pivotally secured to a base. The base is attached to the top of the front end of a mailbox in proximity to, and extending out beyond, the door latch. In a first operative position, i.e. when the mailbox is empty of delivered mail, the rod is in an erect position, and its upper portion extending above the door latch. The rod is colored on its upward portion, i.e. the portion above its pivot point, in order to indicate that the mail has not arrived. In a second operative position, i.e. when the door latch is opened to introduce the daily mail into the mailbox, the rod is caused to pivot into a horizontal position as the latch pushes against the lower portion of the rod. In the horizontal position, the observer cannot see the colored portion of the rod, which now rests in a horizontal cradle of the base. Visual absence of the upright, colored rod indicates that the daily mail has been delivered.
It is an object of the present invention to provide an improved mail indicator.
It is another object of this invention to provide a mail indicator that has minimal moving or working parts, is easy to install, is low in cost, and is reliable.
These and other features and objects of the invention will be more fully understood from the following detailed description of the preferred embodiments considered in conjunction with the accompanying drawings.

The accompanying drawings, which are incorporated in and form a part of the specification, illustrate the embodiment of the present invention and, together with the description serve to explain the principles of the invention.
FIG. 1 illustrates an in situ, side view of the mail indicator of this invention in a first operative position; and
FIG. 2 shows an in situ, side view of the mail indicator of this invention in a second operative position.
FIG. 3 shows an in situ, top view of the mail indicator of this invention.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Generally speaking, the invention comprises a mailbox-indicating device for determining when the daily mail has arrived. The mailbox-indicating device includes a single, pivotally movable element that is attached to a base member that is mounted on top of the mailbox adjacent the door latch. The pivotal element is caused to pivot between an observable and non-observable position in response to the opening of the mailbox door. Delivery of the daily mail (opening of the mailbox door), causes the movable element to pivot to the non-observable position, thus indicating that mail has been delivered.
Now referring to FIG. 1, the mailbox-indicating device 10 is shown in a first operative position, i.e. with an indicator rod 15 in a substantially erect position. The mailbox-indicating device 10 comprises a base member 12 having a groove extending along its top surface 14. The groove accommodates, and hides the indicator rod 15, in its second operative position, as will be observed and explained, with reference to FIG. 2. The bottom 16 of the base member 12 is attached to the top surface 22 of the mailbox 20 adjacent the mailbox door 18, as shown. The base member 12 can be secured to the top surface 14 of mailbox 20, by a pair of self-set screws (not shown). The base member 12 can be made of wood or plastic.
The base member 12 comprises an elongated arm 24, which extends beyond the door 18, as illustrated. The distal end 17 of the elongated arm 24 has a pivot pin 19 extending through, and pivotally engaging with, the indicator rod 15. The arm 15 is operatively pivotal (arrow 28) about pivot pin 19. The indicator arm 15 comprises a brightly colored top portion 11.
Referring to FIG. 2, the mailbox-indicating device 10 is illustrated in a second operative position. It will be observed that the upper portion 27 of the indicator rod 15, with its colored top portion 11, has pivoted into the groove disposed in the top surface 14 of base member 12, and has visually disappeared. It will also be observed that the lower pivotal portion 29 of the indicating rod 15 has now assumed a substantially horizontal position.
OPERATION OF THE INVENTION
Prior to delivery of the daily mail, the indicator rod 15 is positioned in the first operative position, as illustrated in FIG. 1. In this position, the brightly colored top portion 11 of the indicator rod 15 is clearly visible in its upright position. Delivery of the daily mail by the courier, requires that the door 30 of the mailbox 20, be opened. Lower portion 29 of the indicator arm 15 is resting upon door 30. Opening of the door 30, so that the daily mail can be inserted into mailbox 20, forces the lower portion 29 of the indicator rod 15 to pivot (arrow 28) into the substantially horizontal position, depicted in FIG. 2. The colored portion 11 and the upper portion 27 of the indicator rod 15 is now resting in the groove of base member 12. Therefore, the homeowner is able to visually distinguish that the daily mail has arrived.
Upon retrieval of the daily mail, the homeowner resets the indicator arm 15 to the upright position, shown in FIG. 1. In this manner, the mailbox-indicating device 10 is now operationally available for the next day's mail delivery.
In describing a preferred embodiment of the invention illustrated in the drawings, specific terminology has been used for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.
Having thus described the invention, what is to be protected by way of Letters Patent, is presented in the appended claims.
