Abstract:

A structural framing system and apparatus for use in the fabrication of a structural framework of selected geometric configuration of cast material, for example, concrete or plastic. The method and apparatus of the present invention includes a generally hollow hub form defined by a generally continuous shell of selected geometric form to provide a locus for radiating and outwardly extending frame member forms, which communicate with the hub form where a suitable hardenable material is provided to fill the hub form and the frame member forms to provide a self-supporting structural framework of interconnected hubs and frame members, the frame members extending divergently outwardly from the hub members. Structural reinforcements such as reinforcing steel can be attached within the hub to extend divergently outwardly through the frame form members.

Abstract:

In a chair having a frame, a fixed seat, and a pivotal back, the frame includes two bridge-supporting legs extending between an upper position and a lower position behind and below the upper position. A transverse bridge fitting removably into openings in the bridge-supporting legs bridges the bridge-supporting legs in at least two orientations. The bridge limits pivotal movement of the back, when pivoted downwardly and backwardly, to at least two reclined positions. In one contemplated embodiment wherein the transverse bridge comprises a beam fitting removably and nonrotatably into the openings and bridging the bridge-supporting legs in two such orientations, a spacer extending along and mounted fixedly to the transverse beam is interposed between the transverse beam and the back in one such orientation but not in the other orientation. In other contemplated embodiments wherein the transverse bridge comprises a transverse axle, similar spacers mounted fixedly to the transverse beam are interposed between the transverse beam and the back, each spacer having a bearing surface conforming generally to a spiral or to a closed, curved shape when viewed axially and adapted to bear against the back at varying radial distances from the axis.
