ABSTRACT:
An automatically retractable rural mailbox which includes a mailbox which is slideably or rotatably mounted in relation to a fixed frame mounted on a post and which is automatically returned to its normal position by means of a spring. However, the mailbox is returned after being extended only after mail has been deposited in the mailbox and the letter carrier has again closed the mailbox door. This is achieved by a locking bar which locks the mailbox in an extended position, and a releasing bar which unlocks the locking bar and which cooperates with the door of the mailbox.
