Abstract
A portable toy racing set is disclosed which includes a booster for accelerating toy vehicles around a curved track. The booster includes an arm which pivots about an axis perpendicular to the track and offset from the center of a curved portion of the track. A finger depends from the arm and travels from a position adjacent the side of the track to a position which causes it to contact the vehicle.
Claims7
A toy racing set, comprising:
- a track for containing a toy vehicle, including a generally U-shaped curved portion;
- and
- booster means for accelerating the vehicle on the track, including
- an arm which extends over the track at a height which is above that of the vehicle and which is pivotably mounted about an axis substantially perpendicular to the track, the axis being offset from the center of the U-shaped curved portion of the track so that the arm pivoting motion is eccentric with respect to the track, a finger which depends from the arm a distance sufficient to contact the vehicle traveling on the track, means for accelerating the arm about the axis from a first position where the finger is adjacent one side of the track at a point which is clear of the path of the vehicle to a second position where the finger is in the path of the vehicle, whereby by accelerating the arm just after the vehicle has passed the first position, the finger contacts the vehicle and accelerates it as it is moving on the track.
