Abstract
An improved solid state self cancelling motorcycle turn signal system that recognizes when the turn has been completed. The circuit utilizes silicon controlled rectifiers for energizing the motorcycle turn signal lights. Mercury switches are adjusted and connected in said circuit such that when the motorcycle is in an upright position, the switches will open, thus turning off the system.
Claims2
A directional signaling system for motorcycles including;
- first and second normally open push button switches;
- a first silicon controlled rectifier connected to said first normally open push button switch;
- a second silicon controlled rectifier connected to said second normally open push button switch;
- first indicating means connected to said first silicon controlled rectifier;
- second indicating means connected to said second silicon controlled rectifier;
- said first and second indicating means connected to a first electronic switch;
- said first electronic switch connected to a second electronic switch;
- said second electronic switch connected to a power supply;
- a third silicon controlled rectifier connected to said first and second normally open push button switches;
- said third silicon controlled rectifier connected to a third electronic switch, via a plurality of normally closed contacts;
- said third electronic switch connected to said first electronic switch;
- said first normally closed push button switch, when closed, providing an electrical signal to said first and third silicon controlled rectifiers which turn on said first and third electrical switches;
- said second normally closed push button switch, when closed, providing an electrical signal to said second and third silicon rectifiers which turns on said first and third electrical switches;
- and
- a timing control means for providing a timed output signal for intermittently turning on said second electronic switch, resulting in an intermittant current flow through said first electronic switch, said second electronic switch, said indicating means connected to the closed push button switch, said silicon controlled rectifier connected to said indicating means, through said third silicon controlled rectifier and third electronic switch such that when said normally closed contacts open, said electrical energy storing device provides a sufficient electrical signal to keep said third electrical switch turned on for a predetermined period, said third electronic switch in turn keeping said first electronic switch turned on for that predetermined interval.
