Claims
- 1. A fold-away chair adapted to be pivoted from a position of use to a collapsed position, comprising a combined seat bottom and rear leg assembly, a seat back assembly, a front leg assembly, a pair of arm rests, and a sliding pivot assembly to facilitate folding, said combined seat bottom and rear leg assembly comprising laterally spaced side rails having front seat bottom portions and rear leg portions, transverse slats connecting the front seat bottom portions of said side rails, a first transverse load-bearing member connecting the front ends of the front seat bottom portions of said side rails, said front leg assembly comprising laterally spaced front legs, first means pivoting said front legs near their midpoints to the front ends of the seat bottom portions of said side rails, a second transverse load-bearing member connecting said front legs beneath said first pivot means, said seat back assembly comprising longitudinal slats connected near their midpoints by an upper transverse bar and connected near their lower ends by a lower transverse bar, each arm rest having an elongated rib secured to the underside thereof and extending lengthwise thereof from a point near the rear end of said arm rest to a point short of the front end thereof, each front leg having a transverse plate at the upper end thereof, second means pivoting the rear ends of the elongated ribs of said arm rests to said upper transverse bar of said seat back assembly and third means pivoting the front ends of said elongated ribs to the upper ends of said respective front legs, said sliding pivot assembly comprising sliding pivot pins on the ends of said lower transverse bar of said seat back assembly, arcuate tracks on said side rails extending generally lengthwise thereof in which said pivot pins are slidably received, said pivot pins providing the sole means of transferring the load of said seat back assembly and of the rear end portions of said arm rests to said side rails, said tracks having downwardly and forwardly sloping terminal locking portions at their front ends in which said sliding pivot pins are received and retained in the position of use of said chair, the slope of said terminal locking portions being such that said sliding pivot pins lift out of said locking portions with a camming action when said seat back assembly is pushed forwardly to initiate the folding of said chair to a collapsed position, and releasable pins engaging said front legs and the front ends of the seat bottom portions of said rails to lock said chair in its position of use in which, when said chair is supported on a horizontal surface, said front legs are substantially vertical and their transverse plates abut the front ends of said elongated ribs of said arm rests, said combined seat bottom and rear leg assembly slopes downwardly from front to rear, and said first loading-bearing member bears upon said second loading-bearing member at a point well below said transverse slats of said combined seat bottom and rear leg assembly, said chair being foldable when said releasable pins are released to a collapsed position in which, when said collapsed chair is supported on a horizontal surface, said front legs are substantially horizontal and extend generally parallel to said side rails.
