Abstract
A coupling member for a toy vehicle drive system that may be employed in various play situations. The coupling member is generally comprised of an exaggerated triangularly-shaped portion and a funnel-shaped portion. The exaggerated triangularly-shaped portion allows the toy vehicle to be driven forward and backward, and also allows it to complete a U-turn and to be disengaged from the drive chain of the drive system. The funnel-shaped portion ensures that the toy vehicle may be engaged by the driven chain when the child desires to drive the toy vehicle in its forward direction.
