摘要： An adjustable chair includes a base, a back and a chair control for pivotally connecting the back to the base for movement between a fully upright position and an inclined position. A cable actuated variable back stop mechanism includes a generally U-shaped bail or stop lever pivoted to the back. The bail is engageable with a stop on the chair base. A lock member is slideably mounted on the back. The lock member includes a front face defining a plurality of vertically spaced, generally parallel grooves. The grooves are dimensioned to receive the bail and hold the bail in one of a plurality of selected positions when the lock member is moved from an inoperative to an operative position. When in the operative position, the lock member prevents pivoting of the bail when it engages the stop on the base, hence, limiting tilting of the chair back.
摘要翻译： 可调式椅子包括底座，后座和椅子控制器，用于将后背可枢转地连接到基座，以在完全直立位置和倾斜位置之间移动。 电缆致动的可变后挡块机构包括大致U形的吊环或止动杆，其枢转到后部。 保释卡可以与座椅上的停靠点接合。 锁定构件可滑动地安装在背面。 锁定构件包括限定多个垂直间隔开的大致平行的凹槽的前表面。 当锁定构件从不起作用移动到操作位置时，槽的尺寸被设计成接收吊环并将吊环保持在多个选定位置中的一个位置。 当处于操作位置时，当锁定构件接合基座上的挡块时，锁定构件防止吊环枢转，从而限制椅子的倾斜。

摘要： A freestanding privacy screen comprises a plurality of like panels shaped to be positioned in a side-by-side relationship. Each panel includes a frame on which an insert panel can be mounted, and hollow side members or uprights. A pair of hinge rods are positioned in the hollow uprights of the frame for axial rotation therein, and have first key members positioned adjacent opposite ends thereof. Panel connectors interconnect adjacent panels in a mutually vertically aligned relationship. Each panel connector has a two-part body construction interconnected by a removable fastener to capture associated end portions of adjacent hinge rods therebetween. The connectors have second key members that mate with the first key members on the hinge rod ends which rotationally interconnect adjacent hinge rods, such that when the privacy screen panels are pivoted, the hinge rods retain adjacent panels in their vertically aligned relationship.
摘要翻译： 独立的隐私屏幕包括成形为并排定位的多个相似的面板。 每个面板包括可以安装插入面板的框架和中空侧构件或立柱。 一对铰链杆定位在框架的中空立柱中，用于在其中轴向旋转，并且具有邻近其相对端定位的第一键构件。 面板连接器以相互垂直对齐的关系互连相邻面板。 每个面板连接器具有通过可移除的紧固件相互连接的两部分主体结构，以捕获其间的相邻铰链杆的相关联的端部。 连接器具有与铰链杆端部上的第一键构件配合的第二键构件，其旋转地互连相邻的铰链杆，使得当隐私屏幕面板枢转时，铰链杆将相邻的面板保持在垂直对齐的关系中。
