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 center line and have apertures offset from the center line. The leg covers are adapted to cover the legs, and the leg covers including downwardly extending off-centered bosses for engaging the apertures. Each of the tubular legs have an end with aligned vertical holes therein. A sleeve-like pintle retainer is located in the aligned vertical holes and flared at its top and bottom to hold the pintle retainer 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 side walls, the top and bottom walls each having an arcuately shaped end engaging the center hub. A pair of ring welds extend 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.
摘要翻译：椅座包括具有多个径向延伸的腿部的腿部组件和适于覆盖腿部的腿部盖子。管状腿具有由中心线分开的顶表面，并且具有偏离中心线的孔。腿罩适于覆盖腿部，并且腿罩包括用于接合孔的向下延伸的偏心的凸起部。每个管状腿具有在其中具有排列的垂直孔的端部。套筒状的枢轴保持器位于对准的垂直孔中，并在其顶部和底部扩张，以将枢轴保持器保持在管状腿中。腿组件包括管状中心毂。多个径向延伸的管状腿各自具有顶壁，底壁和相对的侧壁，顶壁和底壁各自具有与中心毂接合的弓形端。一对环形焊缝围绕中心毂连续地延伸，用于将顶壁和底壁的弧形端部焊接到中心毂。在改进的形式中，盖包括多个平顶中间保持器，其形状用于附接到腿的顶部，以及多个美观的平底修剪件，其成形为将粘附附件与保持器的顶部配合。

摘要： An armrest construction for chairs includes an armrest support having a lower end constructed for attachment to a chair, an upper end, and a mounting block attached to the upper end. A pivot block is pivoted to the mounting block at a main pivot, the pivot block having an upwardly-extending follower. First and second gears are each pivoted to the pivot block, the gears having intermeshing teeth at an inner end such that rotation of the first gear causes the second gear to simultaneously rotate in an opposite direction, the first and second gears further having outer ends. A support plate having pivot/slide members engages the outer ends of the first and second gears, and further has a guide operably engaging the follower to guide lateral movement of the support plate along a predetermined path. The support plate is rotatable about the main pivot to adjust the angular orientation of the armrest construction and is laterally movable along continuously parallel positions to adjust a width of the armrest construction relative to the chair. The armrest construction is mounted on a vertically-adjustable armrest support member for optimal adjustability.
