    • An improved lightweight metal chair having a number of structural enhancements is disclosed. The flexural rigidity of the frame of the chair seat is enhanced by counters which develop tensile forces to resist flexure incident to the loading of the chair. The legs of the chair are connected to the frame of the seat by gussets which supportingly embrace and grip one or more members of the frame of the seat. The structural interface between the frames of the seat and back of the chair include telescopic connections in which the male member depends from the frame of the seat while the female member is associated with the frame of the back. Rigid arms interconnect the frames of the seat and back. The chair is easily disassembled for compact storage.
    • 公开了一种具有许多结构增强的改进的轻型金属椅子。 椅子座椅的框架的弯曲刚度通过产生张力的计数器增强,以抵抗与椅子的装载有关的挠曲。 椅子的腿通过角撑板连接到座椅的框架,该支撑架支撑并抓住座椅的框架的一个或多个构件。 座椅的框架和椅子的后部之间的结构界面包括伸缩连接,其中阳构件从座椅的框架延伸,而雌构件与背部的框架相关联。 刚性臂将座椅和后背的框架相互连接。 椅子很容易拆卸,便于紧凑的存放。
