Abstract
Abstract A self-supporting table infant chair includes back, seat, and sidewall portions integrally formed from thermoplastic resin material by means of rotational or injection molding techniques so as to form a one-piece bucket-type chair. An upper set of laterally spaced arms project outwardly from the sidewalls of the chair, while a lower arm projects upwardly out of the seat portion of the chair. The upper and lower arms cooperate so as to define a horizontal channel therebetween within which a projecting portion of a dining table can be disposed and from which the chair will be supported. The upper arms comprise the ends of a C or U-shaped tubular member disposed within a horizontal plane, while the lower arm comprises one end of a C or U-shaped tubular member disposed within a vertical plane, the other end of the tubular member being integrally connected to the central portion of the upper arm member whereby the arm members form a one-piece composite member of substantially T-shaped construction. The T-shaped component may either be embedded or encapsulated within the chair or snap-fitted thereinto, blind fasteners serving as fail-safe or redundant fastening means in conjunction with the snap-fit securement system. Anti-tilt projections are also associated with the chair armrests for supporting the chair upon the table in a stable mode.
