Abstract
A unidirectional drive for a multi-part construction toy. A circular first drive element is received within the cylindrical wall of a second drive element. Each drive element has angularly oriented fixed drive teeth projecting toward the other. The outermost dimension of the first drive element is such as to enable it to rotate in one direction within the second drive element, without driving engagement to cause the second element to rotate. At least one of the drive elements is free to move radially with respect to its axis of rotation such that, when rotated in a driving direction, relative radial displacement between the two drive elements causes the respective drive teeth to become positively engaged for maintaining the two drive elements in positive driving relation. An extraordinarily simple and inexpensive one-way clutch drive is achieved.
