ABSTRACT:
A seesaw includes a manually rotatable actuator for adjusting the balance of the seesaw to accommodate a weight differential between two riders. After adjusting the seesaw, the actuator automatically locks the adjustment mechanism in place. A rack-and-pinion assembly provides fine adjustment, and a protective cover avoids creating a pinching hazard.
