Abstract

A child's knock-down chair capable of being assembled without the need for any conventional fasteners and comprised of two side parts and two cross pieces which, due to the unique design of the chair, act respectively as seat and back for a steady chair, and as a back and seat for a rocking chair. Disassembly of the knock-down chair is as simple and straightforward as assembly.

Claims6

Dependent claims

A knock-down chair assembly composed of only four members:

said four members including a pair of identical side pieces and first and second cross pieces;
said side pieces each having a pair of slots communicating with adjacent edges of said side pieces and arranged so that they are oriented substantially at an angle greater than a right angle relative to one another;
said first cross piece having a pair of spaced parallel slots communicating with one edge thereof, and a third slot arranged parallel to and inwardly from said one edge and substantially perpendicular to said pair of slots;
said second cross piece having a pair of slots communicating with one edge thereof and being arranged in spaced parallel fashion;
said second cross piece having an integral elongated projection extending outwardly from said one edge;
the pair of slots of said first cross piece and an associated one of said pair of slots of said side pieces, each slidably receiving one another and extending beyond the slots so that the slots in said side pieces each embrace a portion of said cross piece beyond the parallel slots in the cross piece, and so that the elongated slots in said first cross piece each embrace a portion of one of said side pieces beyond the slots in said side pieces cooperating with the parallel slots in said first cross piece;
the pair of elongated slots in said second cross piece each being slidably received by an associated one of the remaining slots in said side pieces, so that the slots in said second cross piece each embrace a portion of the side pieces beyond the slots received thereby, and so that the remaining slots of said side pieces each embrace a portion of the second cross piece beyond the slots therein;
said third elongated slot in said first cross piece receiving the integral projection of said second cross piece for interlocking said cross pieces to one another and hence, for interlocking said first and second cross pieces and said side pieces;
said side pieces each having an elongated curved side edge, said curved side edge cooperating to rockingly support said chair assembly, whereby said first and second cross pieces, respectively, serve as the rocking chair back and rocking chair seat;
said side pieces each having a pair of integral projections forming a pair of legs along an edge adjacent to and aligned transverse to the curved side edges, said side pieces collectively thereby providing four such legs for supporting said chair assembly when the free ends of such legs rest upon a supporting surface, thereby providing a steady chair.
