Analysis of Time Series Data from the Chesapeake Bay Mouth Cruises

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.
