Abstract
A directional indicator system for vehicles such as automobiles comprises a flasher unit and left hand and right hand marker lamps positioned on the vehicle. The flasher unit causes current to pulse through the marker lamps so that the marker lamps flash. Transmission of current to the marker lamps from the flasher unit is controlled by a timer circuit. The timer circuit includes switches that enables selection of one of the left hand and right hand marker lamps and then provide current to the selected left hand or right hand marker lamps for a predetermined duration. A plurality of timers can be provided and a plurality of time durations can be selected. The system can further comprise a complete turn shut-off switch that prematurely ends the operating duration of the timer circuit when a turn of sufficient radius is completed.
Claims6
A directional indicator system for an automobile comprising:
- a steering wheel operatively interconnected with front wheels of the automobile for steering the front wheels;
- a flasher unit;
- left-hand marker lamps;
- right-hand marker lamps;
- a timer circuit and a control switch circuit interconnected with each of the flasher unit, the left-hand marker lamps and the right-hand marker lamps, the control switch circuit and the timer circuit being constructed and arranged so that operation of the control switch circuit causes the timer circuit to thereby cause one of the left-hand marker lamps and the right-hand marker lamps to flash in response to the flasher unit for a first predetermined time;
- and
- a completed turn cut-off switch operatively connected with the steering wheel and constructed and arranged so that movement of the steering wheel from a turning position to a neutral, substantially-straight-steering position causes at least one of the left-hand marker lamps and the right-hand marker lamps to cease flashing at a time that is less than the first predetermined time.
A directional indicator system for automobiles comprising:
- a steering wheel operatively interconnected with front wheels of the automobile for steering the front wheels including a steering wheel support column for supporting the steering wheel thereon;
- a flasher unit;
- left-hand marker lamps mounted on a body of the automobile;
- right-hand marker lamps mounted on a body of the automobile;
- a timer circuit and a control switch circuit interconnected with each of the flasher unit, the left-hand marker lamps and the right-hand marker lamps, the control switch circuit and the timer circuit being constructed and arranged so that operation of the control switch circuit causes the timer circuit to thereby cause select one of the left-hand marker lamps and the right-hand marker lamps to flash in response to the flasher unit for a first predetermined time;
- and
- a control stalk, interconnected with the control switch circuit, the control stalk including an elongated shaft extending from the support column and having contacts adjacent the support column, the control stalk being movable to a plurality of positions to selectively engage the contacts to select one of the left-hand marker lamps and the right-hand marker lamps to flash for the first predetermined time.
