Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever lock device for exerting a parking brake action on a vehicle that does not have a parking brake, typically a motorcycle.

Vehicles such as motorcycles and reverse strikes with two front wheels hardly have parking brakes.
When such a motorcycle is parked, there is a risk that the vehicle may overturn or the like if the vehicle starts to move carelessly due to the inclination. Especially with sport motorcycles, the increasing number of vehicles with only a side stand presents such fears all the time.
For this reason, if the parking lot is sloping, the user should shift the transmission gear to the low position to connect the rear wheels and the engine, and apply the alternative parking brake by the resistance of the stopped engine. It is in a worn state.
However, when the slope is gentle and the driver is not so conscious of it, such a measure may be forgotten, and furthermore, such a measure cannot be taken with an automatic transmission type scooter or the like.

For this reason, lever holders have been provided on the market that are mainly designed to pull the brake lever forward so that the brake can be maintained in an effective state (see Patent Document 1, for example).
Although each of these has demonstrated its intended function, from the user's point of view, first of all, it should be possible to expect a reliable action in terms of strength, it should be easy to install and remove, and the lever when using There have been various demands, such as that the holder should not damage the highly decorative grip, that security measures should be taken during use, and that the holder should be easy to carry.
From the viewpoint of such demands, it is impossible to find a lever lock device that satisfies them comprehensively.
