Title:
WHEEL FRAME INSTALLED ON TOY CAR AND TRACK TOY CAR
Document Type and Number:
WIPO Patent Application WO/2017/181543
Kind Code:
A1
Abstract:
A wheel frame (1) installed on a toy car, and a track toy car. The wheel frame (1) comprises wheels (4) and a longitudinal rolling mechanism. The longitudinal rolling mechanism allows the horizontal rotating axle (32) to roll around a longitudinal rotation axis arranged in the direction of travel of the toy car, thereby rolling the wheels (4) around a car body (7). When the toy car travels on a curved or changing track, the wheels (4) can roll in cooperation with the curvature or changing form of the track without rolling the car body (7). The invention allows the toy car to achieve faster speeds on a screw-shaped track while reducing a friction between the wheels (4) and a surface of the track.
