Abstract
Abstract A chair frame has a pair of spaced substantially horizontal side members for support of a seat, and said side members are spanned by a fixed panel upon which a chair seat may be superposed and anchored with great ease and despatch and without the use of tools or mechanical ability. The seat carries fastening means to engage the fixed panel either permanently or releasably, whereby the chair is fully prepared for use.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
105 words
A chair comprising a frame and a seat, said frame including a pair of laterally spaced, substantially horizontal side members; a first, frame panel secured at its opposite ends to said side members in spanning relation thereto and bracing said frame; and interlocking fastener and alignment means on said panel and on the undersurface of said seat, said interlocking fastener and alignment means including a plurality of downwardly projecting fasteners on the undersurface of the seat and a plurality of aligned openings through the panel through which the fasteners extend to align and secure the seat relative to said panel and thus to said frame.
Claim 2
Dependent Claim
105 words
A chair comprising a frame and a seat, said frame including a pair of laterally spaced, substantially horizontal side members; a first, frame panel secured at its opposite ends to said side members in spanning relation thereto and bracing said frame; and interlocking fastener and alignment means on said panel and on the undersurface of said seat, said interlocking fastener and alignment means including a plurality of downwardly projecting fasteners on the undersurface of the seat and a plurality of aligned openings through the panel through which the fasteners extend to align and secure the seat relative to said panel and thus to said frame.
