    摘要： A chair construction and method for building a chair having selected features are provided. The construction includes a plurality of interchangeable different components including different base assemblies, back assemblies, seats, arms, and chair controls that can be selected to provide different features on a "customized" chair. The different chair controls are constructed from a selected one of a plurality of interchangeable energy modules and a selected one of a plurality of interchangeable seat support modules. All components include standardized connections for engaging the related components, and further include various mechanisms and designs so that by selecting particular components, a chair having various features and appearances can be provided. For example, the plurality of interchangeable seat support modules include a non-adjustable seat support module, a seat-angle-adjustable seat support module, and a seat-depth-adjustable seat support module. Also, the plurality of interchangeable chair control modules include a non-lockable energy module, a back lockable energy module, and a multi-position backstop energy module, each connectable to a selected one of the aforementioned seat support modules. The modularity of these components facilitates assembly including on-site assembly, repair, and post-assembly upgrading of the chair. Further, the seat support is connected by removable pivot pins to allow assembly, retrofit and/or modification in the field. The tension adjustment mechanism, the seat height actuator mechanism, and the pivot connections are constructed for durability, performance, assembleability, compactness of design, and to minimize the number of and complexity of parts. The method includes selecting modules from a menu of interconnectable/interchangeable modules to construct a chair control, and further selecting modules from a menu of interchangeable components to construct a chair having selected features.

    摘要： A chair base includes a leg assembly having a plurality of radially extending legs, and a leg cover adapted to cover the legs. The tubular legs have a top surface divided by a centerline and have apertures offset from the centerline. The leg covers are adapted to cover the legs, and the leg covers include downwardly extending off-centered bosses for engaging the apertures. Each of the tubular legs has an end with aligned vertical holes therein. A sleeve-like pintle receiver is located in the aligned vertical holes and flared at its top and bottom to hold the pintle receiver in the tubular legs. The leg assembly includes a tubular center hub. The plurality of radially extending tubular legs each have a top wall, a bottom wall, and opposing sidewalls, the top and bottom walls each having an arcuately shaped end engaging the center hub. A pair of ring welds extends continuously circumferentially around the center hub for welding the arcuately shaped ends of the top and bottom walls to the center hub. In a modified form, the covers include a plurality of flat-topped intermediate retainers shaped for attachment to a top of the legs, and a plurality of aesthetic flat-bottomed trim pieces shaped for mating adhering attachment to the top of the retainers.

    摘要： An assembly for mounting the piston rod of a gas spring, such as may be used in adjustable-length chairs, stools, tables or the like, is disclosed. The hub tube used in the assembly is flared outwardly at its lower end to form a shoulder. The washer, to which the end of the piston rod is attached, is supported on the shoulder against movement into the tube. After the washer is placed against the shoulder, the end of the tube is rolled inwardly to contain the washer in the downward direction. The expanded area for support of the washer increases resistance to upward movement of the washer in response to the strong forces exerted by the gas spring. The expanded lower section of the tube also provides an area onto which the legs of the chair may be welded.
