  • Patent number: 8408092
    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.
