<p>A locking track mechanism for a toy speeding car comprises a chassis (1) and at least a pair of locking wheels (21, 22). The locking wheels (21, 22), symmetrically set on the bottom of the chassis (1), can lock and move along a track (5) for the toy speeding car. A movable pedestal (7) of the locking wheels (21, 22) is set on the bottom of the chassis (1). A guiding wheel frame (71) is pivoted to the movable pedestal (7). The locking wheels (21, 22) are installed on the guiding wheel frame (71). The mechanism effectively ensures that the toy speeding car firmly grips the track (5) in a compact manner, so that the car can run at a high speed without getting off from the track (5). The car can be exposed completely out of the track (5), thus enhancing the velocity of the car and the viewing effect. The track (5) in the strip shape also reduces the volume of track, and can be made into various structures, to realize various styles of shuttles of the car.</p> |
