Abstract

A warning device is intended to alert a motorcyclist to retract the auxiliary leg support of the motorcycle before operating the motorcycle. The warning device comprises a detection control unit fastened with the body frame of the motorcycle, a detection element fastened with the wheel of the motorcycle, and a trigger switch fastened with the auxiliary leg support of the motorcycle. In the event that the auxiliary leg support is not retracted, and that the wheel of the motorcycle is in motion at the same time, the signals are transmitted by the detection element and the trigger switch to the detection control unit, thereby causing the detection control unit to trigger the horn of the bicycle to blare.

Claims

1. A warning device of an auxiliary leg support of the motorcycle, said warning device comprising:

a detection control unit fastened with a frame of the motorcycle and connected with a power source switch of the motorcycle such that said detection control unit is actuated by the power source switch of the motorcycle;

a detection element fastened with a wheel frame of the motorcycle for detecting the motion of a wheel rim, said detection element being connected with an input end of said detection control unit; and

a trigger switch fastened with the auxiliary leg support of the motorcycle for transmitting a signal to said detection control unit in the event that the auxiliary leg support is not retracted;

said detection control unit being connected at an output end thereof with a horn of the motorcycle such that said detection control unit causes the horn of the motorcycle to blare at such time when the auxiliary leg support is not retracted and the wheel rim of the motorcycle is in motion at the same time.
