Abstract
Abstract An electrically operated parking indicator to indicate the proper position of a vehicle, e.g., in parking a vehicle in a garage. The parking indicator includes a signalling means, e.g., a light bulb which is actuated when the vehicle is properly positioned, and which signal is automatically de-energized upon the lapse of a predetermined time interval.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
A parking indicator comprising: a housing, a switch operator pivotally mounted on said housing adapted to be activated by a vehicle, an indicating means, an electric circuit for energizing said indicating means, said circuit including a source of electrical energy, and a switch means to momentarily energize said circuit when said switch operator is activated, said switch operator being disposed adjacent said switch means to activate and deactivate said switch means upon the displacement thereof, a triggered switching means disposed in series circuit with said indicating means for energizing said indicating means when said switching means is rendered conductive, and including trigger means connected to said switch means for momentary energization thereby to render the switching means conductive, automatically operated means in circuit with said indicating means for de-energizing the circuit thereto after a lapse of a predetermined time interval, said indicating means including a flasher lamp, and said automatically operated means comprising a thermal switch disposed in said lamp.
Claim 2
Dependent Claim
160 words
A parking indicator comprising: a housing, a switch operator pivotally mounted on said housing adapted to be activated by a vehicle, an indicating means, an electric circuit for energizing said indicating means, said circuit including a source of electrical energy, and a switch means to momentarily energize said circuit when said switch operator is activated, said switch operator being disposed adjacent said switch means to activate and deactivate said switch means upon the displacement thereof, a triggered switching means disposed in series circuit with said indicating means for energizing said indicating means when said switching means is rendered conductive, and including trigger means connected to said switch means for momentary energization thereby to render the switching means conductive, automatically operated means in circuit with said indicating means for de-energizing the circuit thereto after a lapse of a predetermined time interval, said indicating means including a flasher lamp, and said automatically operated means comprising a thermal switch disposed in said lamp.
Claim 3
Dependent Claim
59 words
The invention as defined in claim 1 wherein said switch means includes a pair of switches wired in series with said source of energy, one of said switches being normally open and the other normally closed, said switches being connected in series, and said switches being alternately actuated by said switch operator upon the displacement thereof by a vehicle.
Claim 4
Dependent Claim
44 words
The invention as defined in claim 1 wherein said triggered switch means includes a silicon control rectifier connected in circuit between said indicating means and said source of electrical energy whereby said silicon control rectifier is energized by the momentary energizing of said circuit.
