Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to a kick start device for motorcycles and other vehicles.

Conventionally, this type of device is known to have a fan-shaped kick gear on a kick shaft that is rotated in one direction against a spring or other return means when the kick pedal is depressed. While rubber or other dampers are provided for actuation, there is no such means for the stepping side, for example, it is generally applied directly to the case or supported by a stopper metal fitting. Because objects are directly subjected to impact force due to stepping force,
Each part needs to be reinforced, tightened parts tend to loosen, and there is also the problem of noise upon impact, which is undesirable.

The object of the present invention is to provide a device free from such inconveniences, and the top of the kick shaft 3 is rotated between the depressed side and the returned side by the depression of the kick pedal 1 and a spring or other return means 2. In the one in which the fan-shaped locking gear 4 is fixed to the
a pair of rubber dampers 5 facing each other on the stepping side and the returning side in the rotation locus of the tight gear 4;
5 is provided, and the rubber dampers 5 are connected by a cover 6 made of a metal plate fixed on the side facing the hard gear 4.

In the drawing, 7 indicates a support frame on the vehicle body side that supports the root of the shaft 3, and the damper 5 is superimposed on the support frame 7 at a bracket 8 which is fixed to the other side by baking or other means and is fixed thereto with screws 9. I made it so that it would be done. In the illustrated example, the pair of dampers 5, 5 have a cavity 10 in the middle, and are integrally molded at the thin film portions 11, 11 on both outer sides thereof, thus achieving good vibration isolation. At the same time, the damper characteristics are improved by the cavity 10, and the overall size can be reduced. However, the dampers 5, 5 are not formed integrally as in the embodiment, but may be formed separately. You can.

To explain its operation, the hard gear 4 has a cover 6 attached to the rubber dampers 5 facing each end surface in both the clockwise return operation and the counterclockwise depressing operation in FIG. It is supported and buffered through the cover 6, thus eliminating the above-mentioned inconvenience caused by the type that hits the case or the stopper metal fitting during the operation on the stepping side, and furthermore, the cover 6
When one of the rubber dampers 5, 5 is compressed, it applies tension or shear force to the other rubber damper, thereby dispersing the impact force.

In this way, according to the present invention, a pair of rubber dampers 5, 5 are provided on the stepping side and the returning side of the rotational locus of the twisting gear 4, respectively, so that the tightening shaft 3 is provided on the returning side and pushing side. The pair of rubber dampers 5, 5 are connected by a metal cover 6 fixed on the side facing the tight gear 4. Therefore, when one of the rubber dampers 5 is compressed, the other rubber dampers 5, 5 function to disperse the impact force by applying a tensile or shearing force to the other, and have the effect of improving damper characteristics and reducing the overall size.
