Abstract

Abstract A circuit arrangement for the turn-indicator blinker lights of a motor vehicle, especially of a motorcycle, with an acoustic control device coordinated to the operation of the blinker lights; the control device is disconnected when the force-transmission of the motor vehicle is interrupted, while a time control switch engages the control device with a predetermined delay after the beginning of the operation of the blinker light when the force-transmission is engaged and/or after the force-transmission has been re-engaged during the operation of the blinker-lights.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 90 words
A circuit arrangement for the turn-indicator blinker lights of a motor vehicle, comprising an acoustic control device coordinated to the operation of the blinker lights, characterized in that the control device is rendered inoperable by an interruption in the force-transmission of the motor vehicle, and in that a time-control switch means is operable to engage the control device with a predetermined delay after the beginning of the operation of the blinker lights with a closed force-transmission and/or after the closing of the force-transmission during the operation of the blinker lights.
Claim 2
Dependent Claim 90 words
A circuit arrangement for the turn-indicator blinker lights of a motor vehicle, comprising an acoustic control device coordinated to the operation of the blinker lights, characterized in that the control device is rendered inoperable by an interruption in the force-transmission of the motor vehicle, and in that a time-control switch means is operable to engage the control device with a predetermined delay after the beginning of the operation of the blinker lights with a closed force-transmission and/or after the closing of the force-transmission during the operation of the blinker lights.
Claim 3
Dependent Claim 16 words
A circuit arrangement according to claim 1, characterized in that the motor vehicle is a motorcycle.
Claim 4
Dependent Claim 16 words
A circuit arrangement according to claim 2, characterized in that the control device is a buzzer.
Claim 5
Dependent Claim 29 words
A circuit arrangement according to claim 3, characterized in that the control device is rendered inoperable by the time-control switch means by disengaging the clutch of the motor vehicle.
Claim 6
Dependent Claim 34 words
A circuit arrangement according to claim 4, characterized in that the control device is rendered inoperable by the time-control switch means by engaging the neutral position of the change-speed transmission of the motor vehicle.
Claim 7
Dependent Claim 54 words
A circuit arrangement according to claim 5, characterized in that the time-control switch means includes a condenser which is charged during the operation of the blinker lights and which is discharged with an interrupted force-transmission and whose voltage above a predetermined thereshold value controls the closing of an energizing circuit for the control device.
Claim 8
Dependent Claim 57 words
A circuit arrangement according to claim 6, characterized in that the condenser controls by way of a Zener diode as threshold switch a control transistor for a switching transistor having a collector circuit, and a control relay means for the control device and having an energizing coil, said energizing coil being operatively connected in said collector circuit.
Claim 9
Dependent Claim 29 words
A circuit arrangement according to claim 1, characterized in that the control device is rendered inoperable by the time-control switch means by disengaging the clutch of the motor vehicle.
Claim 10
Dependent Claim 34 words
A circuit arrangement according to claim 1, characterized in that the control device is rendered inoperable by the time-control switch means by engaging the neutral position of the change-speed transmission of the motor vehicle.
Claim 11
Dependent Claim 54 words
A circuit arrangement according to claim 1, characterized in that the time-control switch means includes a condenser which is charged during the operation of the blinker lights and which is discharged with an interrupted force-transmission and whose voltage above a predetermined threshold value controls the closing of an energizing circuit for the control device.
Claim 12
Dependent Claim 57 words
A circuit arrangement according to claim 10, characterized in that the condenser controls by way of a Zener diode as threshold switch a control transistor for a switching transistor having a collector circuit, and a control relay means for the control device and having an energizing coil, said energizing coil being operatively connected in said collector circuit.
