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.

Dependent claims

A safety device on a steering handle, positioned on a wheeled vehicle having a direction-control wheel, comprising:

a head part, connected with a chassis of the wheeled vehicle for driving the direction-control wheel;
a handlebar, joined to the head part;
a buffer assembly, allowing the handlebar to rotate when hit by an external impact force and at the same time maintaining the original direction of the direction-control wheel as the handlebar is hit by the external force;
and
a tenon, positioned on the head part and the handlebar further comprises an outer bar and an inner tube, wherein the handlebar is engaged with the head part by the tenon for controlling the direction-control wheel of the wheeled vehicle,
and wherein the buffer assembly further comprises a balance terminal, positioned at the other end of the outer bar joined to the head part and joined to the outer bar with a bolt, wherein the balance terminal is employed to push the inner tube for disengaging the tenon to rotate the handlebar.
