A laterally retractable and longitudinally foldable chair having a plurality of transverse struts connected with a plurality of longitudinal support members to form hingedly connected sub assemblies of a chair frame for supporting an individual. Each strut is provided with adjusting means. Each adjusting means has a locking means associated therewith which allows for selective adjustment of the width of said chair between a retracted, or compact, configuration and an expanded, or in use, configuration. The adjusting means is comprised of a projection and cooperating aperture in each said transverse strut which allows one to releasably lock the chair in the expanded or retracted position as desired. The novel chair further comprises a plurality of hinge members which hingedly connect the longitudinal support members and which allow the individual sub assemblies to be folded upon themselves to futher reduce the collapsed dimensions of the chair. The hinge members are comprised of a linking means which allows for effective and unencumbered folding of the chair. The transverse struts may connect to the side rails of the chair at either the hinge points or at any intermediate point therein. The hinge members are contructed and arranged so that when the chair is expanded longitudinally they will support weight and not collapse into a folded configuration.

An expandable and retractable chair comprised of: a foldable chair sub frame comprised of a plurality of rectangularly interconnected transverse and longitudinal strut sub assemblies, one sub assembly hingedly connected to the other by hinge means; leg means hingedly connected to said chair sub frame for supporting same above a support surface; said transverse struts being selectively telescopingly extendable or retractable to thereby selectively increase or decrease the width of the chair; wherein the transverse struts are each comprised of a pair of telescopingly slideable sleeve members having a cooperating locking means for locking said telescoping sleeve members against relative movement with each other in a first, retracted position or alternatively in a second, expanded position; wherein said locking means is comprised of a spring biased tab adapted to be received by aligned apertures defined by said sleeve members of said transverse strut, said spring biased tab being normally biased into a position partially within said aligned apertures by a coil spring, said coil spring being located entirely within said sleeve members.
