ABSTRACT:
The following specification describes a baby feeding table or high chair raised to a feeding position or lowered to a play position by changing the angle between one pair of parallel tubular legs pivotally connected to another pair of parallel tubular legs intermediate their ends. The one pair of parallel legs are pivotally secured to the table top at positions spaced intermediate the baby's chair and the table edge and the other pair of parallel legs are pivotally supported from the table top by a U-shaped lever bar, which is pivotally connected with both the other pair of legs and the table top at positions spaced intermediate the chair and the table edge.
A cross bar extends between the legs and has ends overlappingly engaged with one pair of legs coincident with the pivot connection to other pair of legs for stabilizing the legs. Washers in the cross bar secure the pivot pins between the legs. The bar also carries a pivotable U-shaped latch rod for engaging the lever bar to secure the table in the feeding position.
Thrust washers located between the legs at the respective pivots distribute the forces and stabilize the connections.
The legs are formed of separable upper and lower sections for facile packing and shipping. The sections include plastic stabilizing rings for reinforcing the assembly sections, which are secured to each other by a spring biased pin in one section engaging a hole in the mating section. Casters are provided on selected lower leg sections for rolling support of the table.
