Abstract

A mail delivery indicator system comprises a minimum number of parts, namely, an indicator flagstaff with a flagged end and a weighted end, a sidewall mounting bracket and a latch element. A pivotal bolt attaches the indicator flagstaff to a side wall mounting bracket, which is then attached to a side wall of a mailbox. When the mailbox front door is opened, the latch element releases the flagged end to traverse rotationally backward away from the mailbox front door by the force of gravity associated with the weighted end of the indicator flagstaff. A weight element pivotally attached to the weighted end of the indicator flagstaff controls the traversing motion of the indicator flagstaff to a generally vertical signaling position to display the indicator flag above the mailbox, visible from a variety of directions. One can use one hand to lower the flagged end to the latch element on the mailbox front door to reset the mail delivery indicator system.

Claims2

Dependent claims

A mail delivery indicator system designed for a mailbox having side walls and a front door pivotally mounted thereon, comprising:

a) an elongated delivery indicator flagstaff with a flagged end and a weighted end;
said elongated delivery indicator flagstaff being maintained in a generally horizontal position when said flagged end engages a latch element on said front door;
b) said elongated delivery indicator flagstaff being pivotally attached to a side wall mounting bracket means, whereby when said front door is opened, said latch element releases said flagged end to traverse rotationally backward away from said front door to a generally vertical signaling position by the force of gravity associated with said weighted end;
c) said weighted end comprises an indicator flag stand element and a weight element;
d) said weight element being pivotally attached at a pivotal point to said indicator flag stand element of said elongated delivery indicator flagstaff;
and
e) said pivotal point for said weight element being positioned above the center of gravity of said weight element to always display a correct, upright posture of said weight element.
