Abstract
Abstract A mailbox provided with a first signal flag mounted for rotation between a first position indicating the presence of mail in the box to be picked up by the mail carrier and a second, neutral position is disclosed. A flange depending from the first signal flag is adapted to frictionally engage a portion of the mailbox door when the first signal flag is in the first position thereby retaining the first signal flag in the first position. When the mailbox door is opened, for example, by a mail carrier, the frictional engagement is broken and gravity causes the first signal flag to rotate to the second, neutral position. The mailbox is provided with a second signal flag mounted for rotation between a first position indicating that a mail carrier has opened the mailbox door to insert mail and a second, neutral position. The second signal flag has a depending flange adapted to be engaged by a portion of mailbox door when the second signal flag is in the neutral position, as the mailbox door is moved from a closed position towards an open position. Continued movement of the door towards the open position causes rotation of the second signal flag to the first position where it can be frictionally held. In one embodiment, the mailbox door and the first and second signal flags are mounted for rotation about a common axis.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
227 words
A mailbox comprising, a housing having an open forward end, side and top wall portions and a floor defining a mail receiving cavity, a door hinged at its lower end for rotation about an axis between a first, closed position and a second, open position, a first signal flag mounted on the mailbox for rotation about said axis between a first, mail-in-box position and a second, no mail-in-box position, first latch means integral with said first signal flag, said last-named means being operable, when said first signal flag is moved from the second position to the first position to retain said first signal flag in said first position until the door is rotated from the first position, whereupon said first signal flag is rotated by gravity from said first position to said second position, a second signal flag mounted on the mailbox for rotation about said axis between a first, not visited position and a second, visited position, edge means integral with said door, said last-named means being operable, as said door is rotated from the first position to the second position, to engage a portion of said second signal flag and to cause rotation thereof from said first position to said second position, and second latch means for retaining said second signal flag in the second position when said door is rotated from the second position.
Claim 2
Dependent Claim
227 words
A mailbox comprising, a housing having an open forward end, side and top wall portions and a floor defining a mail receiving cavity, a door hinged at its lower end for rotation about an axis between a first, closed position and a second, open position, a first signal flag mounted on the mailbox for rotation about said axis between a first, mail-in-box position and a second, no mail-in-box position, first latch means integral with said first signal flag, said last-named means being operable, when said first signal flag is moved from the second position to the first position to retain said first signal flag in said first position until the door is rotated from the first position, whereupon said first signal flag is rotated by gravity from said first position to said second position, a second signal flag mounted on the mailbox for rotation about said axis between a first, not visited position and a second, visited position, edge means integral with said door, said last-named means being operable, as said door is rotated from the first position to the second position, to engage a portion of said second signal flag and to cause rotation thereof from said first position to said second position, and second latch means for retaining said second signal flag in the second position when said door is rotated from the second position.
Claim 3
Dependent Claim
32 words
A mailbox as claimed in claim 1 wherein said first latch means comprise depending tabs adapted to frictionally engage a portion of said door when said door is in the first position.
Claim 4
Dependent Claim
43 words
A mailbox as claimed in claim 1 wherein said second latch means comprise a flange depending from said second signal flag, said flange being configured to frictionally engage a portion of the mailbox when said second signal flag is in the second position.
Claim 5
Dependent Claim
245 words
A mailbox comprising, a housing having an open forward end, side and top wall portions and a floor defining a mail receiving cavity, a door hinged at its lower end for rotation between a first, closed position and a second, open position, a first signal flag mounted on the mailbox for rotation between a first, mail-in-box position and a second, no-mail-in-box position, at least one tab depending from said first signal flag adapted to enter into frictional engagement with a portion of said door when it is in the first position and said first signal flag is in said first position, stop means for preventing rotation of the first signal flag from the second position past said first position, a second signal flag mounted on the mailbox for rotation between a first, not visited position and a second, visited position, a shoulder provided on said second flag configured and positioned so that when said second flag is in the first position, said shoulder is engaged by a portion of said door when it is rotated from the first position to the second position so that this rotation is transmitted to the second signal flag causing it to rotate from the first position to the second position and a tab depending from said second signal flag configured to frictionally engage a portion of a mailbox when said second signal flag is in the second position, thereby frictionally retaining said second signal flag in said second position.
Claim 6
Dependent Claim
245 words
A mailbox comprising, a housing having an open forward end, side and top wall portions and a floor defining a mail receiving cavity, a door hinged at its lower end for rotation between a first, closed position and a second, open position, a first signal flag mounted on the mailbox for rotation between a first, mail-in-box position and a second, no-mail-in-box position, at least one tab depending from said first signal flag adapted to enter into frictional engagement with a portion of said door when it is in the first position and said first signal flag is in said first position, stop means for preventing rotation of the first signal flag from the second position past said first position, a second signal flag mounted on the mailbox for rotation between a first, not visited position and a second, visited position, a shoulder provided on said second flag configured and positioned so that when said second flag is in the first position, said shoulder is engaged by a portion of said door when it is rotated from the first position to the second position so that this rotation is transmitted to the second signal flag causing it to rotate from the first position to the second position and a tab depending from said second signal flag configured to frictionally engage a portion of a mailbox when said second signal flag is in the second position, thereby frictionally retaining said second signal flag in said second position.
