Abstract: The present invention describes a device for locking a lever of a motor vehicle. The device permits an operator to quickly lock the lever in an engaged position and unlock the lever from the engaged position. The device may be used even when the manual dexterity of the operator is limited by protective equipment. The device includes a pin and spring. The pin passes through aligned holes in the flange and lever. Releasing the lever exerts a lateral force on the pin, thereby preventing the pin from lifting from the lever hole and locking the lever in the engaged position. The spring lifts the pin from the locked position when the lateral force is reduced. The device may be used on a brake or clutch lever of a motorcycle, thereby permitting the operator to have at least one free hand at a stop.

Abstract: Disclosed is a safety device on a steering handle, capable of controlling a direction-control wheel of a wheeled vehicle. The handlebar is engaged with the head part by its mortise with a tenon of the head part. When an outer bar end of the handlebar is hit, an inner tube of the handlebar will be pushed to disengage the mortise and the tenon to rotate the handlebar along. Alternatively, paired washers with wedge-shaped teeth can be utilized to engage the handlebar with the head part. When the outer bar end is hit, the washers are disengaged to allow the handlebar to rotate. Moreover, a hydraulic system or an inserting rod with a chassis groove system can be employed to maintain the original direction of the direction-control wheel when the handlebar is hit. Therefore, a sudden turn of the direction-control wheel and an fall-over of the rider and the vehicle can be prevented.

Abstract: A structure for sufficiently spacing a steering handle from a top bridge, thereby greatly improving design flexibility. A relief portion for allowing the deformation of a washer is formed to overlap a second contact surface and adjacent to a first contact surface as viewed in the axial direction of each bolt member. The first contact surface is located so as not to overlap the second contact surface as viewed in the axial direction of each bolt member. Therefore, a bending force acts on the washer to allow the deformation of the washer. That is, the washer can exhibit a spring function to relax the effect of the bending force. As a result, the steering handle can be sufficiently spaced from the top bridge to thereby greatly improve design flexibility.
