ABSTRACT:
A convertible chair for children supported by two pairs of curved pivotally connected and extendable cross legs that serve as rockers when the chair is in its lowered or nested position. Two pairs of pivotally connected and extendable cross arms are attached at one end to the ends of the cross legs, and at their other ends make pivotal connections to a skirt below the chair seat. Separation of the cross arms and cross legs permits converting the rocking chair to a high chair having stable support on the ends of the extended cross legs. The pairs of cross legs, cross arms, and chair skirt are pivotally joined together by transverse rungs. Cam apertures in the forward sections of the chair skirt, and a control rung which passes through the apertures, control the chair extension, and in conjunction with locking pawls on the interior surface of the chair skirts permit locking the chair in its position as a rocker or high chair. The orientation of the cam apertures establishes a rearward tilt to the chair in either operating position.
