Claim 18:
19. The domino-type torque generator according to claim 2, wherein the at least one path includes a path with sharp turns, and the domino-type torque generator comprises:
a vertical bar pivotally connected to an upper end of a first upright support at a first pivot point located at a lower end of the vertical bar;
a first bar extending from an upper end of the vertical bar in a first direction, the first bar being pivotable about the first pivot point between an up position and a down position;
a switch member extending from the lower end of the vertical bar in a second direction opposite the first direction, the switch member being pivotable about the first pivot point between an up position and a down position, the first bar being longer than the switch member so that the first bar topples from its up position to its down position by its own weight when the switch member is disengaged;
a second bar pivotally connected to an upper end of a second upright support at a second pivot point offset from a center of the second bar, and forming a short portion and a long portion on opposite sides of the second pivot point, the short portion of the second bar urging upwards against an underside of the first bar due to a downward force of the long portion of the second bar, the short portion of the second bar being pivotable between an up position and a down position;
a third bar pivotally connected to an upper end of a third upright support at a third pivot point offset from a center of the third bar, and forming a short portion and a long portion on opposite sides of the third pivot point, the short portion of the third bar urging upwards against an underside of the short portion of the second bar due to a downward force of the long portion of the third bar, the short portion of the third bar being pivotable between an up position and a down position; and
a last bar pivotally connected to an upper end of a fourth upright support at a fourth pivot point offset from a center of the last bar, and forming a short portion and a long portion on opposite sides of the fourth pivot point, the short portion of the last bar urging upwards against an underside of the short portion of the third bar due to a downward force of the long portion of the last bar, the short portion of the last bar being pivotable between an up position where the short portion of the last bar is disengaged from the switch member and a down position where the short portion of the last bar is engaged with and pressing on an upper side of the switch member.
