Capozi Attorney-Bean and Bean ABSTRACT: A signal attachment for a mailbox having a hinged door, comprising a lever arm adapted to be pivotally ranged that when the mailman opens the door to deposit mail in the box, the signal arm is pulled upwardly into an upstanding attitude, whereby the signal plate portion thereof is erected into prominently displayed position.

SIGNAL FOR MAILBOXES BACKGROUND AND BRIEF SUMMARY OF THE INVENTION This invention relates to an improved signal device for mailboxes; and more particularly to suburban or rural mailboxes such as are roadside located at considerable distances from the corresponding residences. Under such conditions, the home occupant often fails to observe the mail carrier when making his rounds; and as a result it is desirable to provide a signal device which may readily be attached to a conventional mailbox and initially set by the householder in an inconspicuous place so that it will later move automatically into a position which is readily visible from the residence when the mailbox door is opened by the mailman. Thus, the signal device will now visibly indicate to the householder that the mailbox now contains mail, packages, messages, or the like.

Although numerous such devices have been previously developed, they have involved certain disadvantages and/or inadequacies; and it is an object of this invention to provide an improved signaling device as aforesaid which is simple and inexpensive in construction; and which may readily be applied to any standard-type mailbox without requiring use of any spe cial tools or any alteration of the standard mailbox construction.

More specific objects and advantages of the invention will be apparent from the following description and the accompanying drawing.

FIG. 5 is an enlarged scale sectional view taken on line 55 of FIG. I.

DETAILED DESCRIPTION OF THE INVENTION The invention as illustrated herein is shown as being mounted on a conventional-type mailbox which is generally designated by the numeral and comprises a combination sidewall and roof sheet metal member I2 and a door 14 forming the front end wall of the box. The door 14 is formed with a rearwardly extending flange 15. The door 14 is typically held in closed position by a spring metal keeper device 17 extending fonvardly of the mailbox, and a spring metal strike device I8 extending forwardly of the top end of the door 14; the door 14 being hinged to the box 10 as indicated at 19.

The signaling device per se is designated generally by the numeral 20, and comprises an arm 22 having at its free end a tab or flag portion 25. The flag portion 25 and the arm 22 may be fabricated or molded of plastic or metal, or the like. Preferably, the member 25 will be colored red, or may be otherwise ornamented as desired so as to render it visually conspicuous when it stands above the mailbox as shown at FIGS. 2, 3. The arm 22 is pivotally mounted at one end on the mailbox by means ofa suitable adjustable member such as the bolt 26 and nut 26; and is also engaged as shown by one end of a chain 27 formed of brass or other suitable material. The other end of the chain 27 is connected as indicated at 28 to the spring strike member 18.

Thus, it will be appreciated that the unit comprising the arm 22 and the chain 27 and the bolt or screw 26 may be easily fabricated and assembled as a single package for retail sale; and that the average do-it-yourselfer" may easily attach it to a mailbox as shown herein, without any special tools or difficulty of any kind. The complete attachment may be made by simply inserting the bolt 26 through the aperture furnished in one end of the arm 22 and then through one of the holes which is typically provided by the mailbox manufacturer along the bottom edge of the box (FIG. 4) and then affixing the nut 26. One end of the chain 27 is then hooked onto the arm 22 and its other end is then connected to the door spring keeper 18 by means of the bolt or S-hook 28, thereby completing the installation.

To set" the device for automatic operation, the mailbox door 14 is closed and the arm 22 is simply swung downwardly into position shown at FIG. I, whereupon it is frictionally held by the compression bolt connection 26 against the sidewall portion of the box 10. The most color-prominent part 25 of the arm is thus disposed horizontally and closely alongside the mailbox in an inconspicuous position, until such time as the mailman subsequently opens the door to deposit mail therein. Such operation of the door causes the arm 22 to be elevated to the position shown at FIGS. 2, 3; whereupon the signal portion 25 thereof stands up above the box l ll so that the entire colorprominent portion of the device is disposed in clear long distance view therefrom.

Thus the householder may readily recognize when and if mail has been left in the box, simply by looking out from the house from time to time. Needless trips to the mailbox are thus avoided, such as when the mailman is late on his route, and/or when there is no mail for the householder on any routine delivery trip. Thus, an important safety device is provided for householders such as where the mailbox is required to be located across a roadway from the residence. In such situations fatal traffic accidents often occur simply because of useless multiple pedestrian trips of householders across adjacent highways. Also, such householders are thereby often necessarily exposed to the rigors of inclement and unhealthy weather conditions on such trips. It is therefore obvious that many lives and illnesses may be spared by eliminating any needless trips to such mailboxes; in proportion to the number of necessary trips which are so saved.

It is a particular feature of the invention that the means effecting pivot connection of the arm is of compressional and friction inducing nature. Thus, the signal arm 22 is at all positions frictionally held in place against any accidental dislodgements. However, note that the pivotally mounted end portion of the arm 22 is laterally offset relative to the major portion of the arm, whereby the major portion of the arm is disposed in substantially parallel and spaced relation from the sidewall of the mailbox. This arrangement obviates any mechanical interferences with operation of the device and/or incidental scraping disfigurations of the mailbox sidewall. Also, because the chain 27 pulls upon the arm 22 in a direction out of line with the pivot joint 26, the system provides the mailman with an ample mechanical advantage when opening the door. Hence, friction forces attendant weathertight fittings between the box and door parts are easily overcome, and constitute no disadvantages from the standpoint of the mailman.

Thus it will be appreciated that the invention provides a structurally simple, durable, and inexpensively made device for its specific purpose. In addition to the advantage of being so uncomplicated and trouble free in its installation and use, the device features long life and maintenance-free smooth operation. Furthermore, throughout its operative range, the movable parts of the device never protrude to any substantial extent away from the mailbox such as would be dangerous to passersby, such as nearby playing children, pets, or the like.

It is still another feature and advantage of the invention that because of the geometrical relationship of the operative parts, when the spring member is initially pulled upon by the mailman to open the door 14, the pull of the chain 27 against the arm 22 reacts to draw downwardly upon the spring member 18, thereby assisting in release of the abutment portion 30 of the strike 18 (FIG. 5) from within the complementary dwell portion of the keeper 17. Thus, manual opening of the door 14 is facilitated, whereas the keeper normally operates with unimpaired efficiency to maintain the door against any accidental opening.
