Abstract
Abstract A signaling device for being coupled to a mailbox of the type having a cantelievered tongue section defined below the mailbox door hinge. A snap-type single pole single throw (SPST) push on push off action switch is coupled to the base of the mailbox adjacent to the tongue section of the door for generating a first signal responsive to the operative communication between the tongue section of the door as the door is opened. An electrical circuit is coupled to the switch for generating a sensory perceptible signal responsive to receiving the first signal from the switch. The switch is mounted on a generally U-shaped bracket which may be deformable as the switch is being actuated, thereby reducing the possiblity of damage to the switch as the door is opened.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
237 words
A signaling device for being coupled to a mailbox of a type including a generally horizontal base and an upward extending container coupled thereto for defining an entryway and a storage compartment therein, a door for closing over the entryway, a hinge coupled between the base and a section of the door above a lower edge thereof so as to define a lower cantilevered tongue section of the door which rotates toward the base as the door is opened, said signaling device comprising in combination: switch means mounted adjacent a lower surface of the base and adjacent to the tongue section of the door for generating a first signal responsive to operative communication with the tongue section of the door as the door is opened; a U-shaped bracket having said switch means coupled to a central deformable section thereof and further having distended ends thereof coupled to the base for support, said central deformable section of said U-shaped bracket being flexible in order to deform responsive to an additional opening displacement of the door beyond that displacement necessary in order to actuate said switch means, whereby said switch means may be located immediately adjacent to the tongue section of the door for sensing small displacements thereof without being damaged by unexpectedly large displacements of the door; and electrical signal means coupled to said switch means for generating a sensory perceptible signal responsive to receiving said first signal.
Claim 2
Dependent Claim
237 words
A signaling device for being coupled to a mailbox of a type including a generally horizontal base and an upward extending container coupled thereto for defining an entryway and a storage compartment therein, a door for closing over the entryway, a hinge coupled between the base and a section of the door above a lower edge thereof so as to define a lower cantilevered tongue section of the door which rotates toward the base as the door is opened, said signaling device comprising in combination: switch means mounted adjacent a lower surface of the base and adjacent to the tongue section of the door for generating a first signal responsive to operative communication with the tongue section of the door as the door is opened; a U-shaped bracket having said switch means coupled to a central deformable section thereof and further having distended ends thereof coupled to the base for support, said central deformable section of said U-shaped bracket being flexible in order to deform responsive to an additional opening displacement of the door beyond that displacement necessary in order to actuate said switch means, whereby said switch means may be located immediately adjacent to the tongue section of the door for sensing small displacements thereof without being damaged by unexpectedly large displacements of the door; and electrical signal means coupled to said switch means for generating a sensory perceptible signal responsive to receiving said first signal.
Claim 3
Dependent Claim
44 words
The signalling device as described in claim 1 wherein said switch means comprises a longitudinally movable snap-action switch which locks into a closed condition upon being first depressed, and which must be released and again depressed in order to revert to an open condition.
Claim 4
Dependent Claim
31 words
The signaling device as described in claim 1 wherein said U-shaped bracket is located within a generally rectangular recessed area beneath the base as defined by the base and the container.
Claim 5
Dependent Claim
24 words
The signaling device as described in claim 1 wherein said electrical signal means further includes disable switching means for disabling said sensory perceptible signal.
Claim 6
Dependent Claim
92 words
The signaling device as described in claim 1 further including first and second circuit means operatively interposed between said switch means and said electrical signal means for transmitting said first signal therebetween, with said first circuit means being inductively coupled between said switch means and one section of the household electrical service, and with said second circuit means being inductively coupled between a second section of household electrical service and said electrical signal means, whereby said first signal is transmitted over the same existing household electrical system conductors which supplies power thereto.
Claim 7
Dependent Claim
77 words
The signaling device as described in claim 5 wherein said electrical signal means comprises a light bulb electrically coupled to a transformer and each mechanically attached to a signal box, with the primary leads of said transformer extending from said signal box in the form of a male connector of the type for coupling with a standard electrical wall receptable, said transformer being powered and supported by said male connector coupled into the standard electrical wall receptable.
Claim 8
Dependent Claim
61 words
The signalling device as described in claim 1 further including at least one electrical solenoid coupled to the base adjacent to the tongue section of the door, with said solenoid for extending into communication with the tongue section of the door for limiting the opening movement of the door responsive to said solenoid receiving said first signal from said first means.
Claim 9
Dependent Claim
42 words
The signalling device as described in claim 7 wherein said solenoid electrically moves into and out of an extended position and wherein said solenoid further includes mechanical latching means controlled by said first signal for locking said solenoid into said extended position.
