摘要： This lockset has a threaded inside sleeve extending out from its central housing, the sleeve enclosing the inside spindle for the lockset. An inside rose and handle assembly is provided, the rose having inward tabs. A nut is threaded onto the sleeve and has spaced openings about its end remote from the housing, the openings each leading to a series of steps in clockwise direction progressively closer to the housing. Each step has a tread and a riser so that when the handle is brought over the spindle and the rose is maneuvered so that the tabs fit into the openings and the rose is turned in a clockwise direction, the tabs will engage the closest riser to the housing that the thickness of the door will permit. Further clockwise turning of the rose will turn the nut and move the nut closer to the housing so that the treads engage the tabs and draw the rose/handle assembly inward to firmly and quickly install the lockset on the door.
摘要翻译：该锁具具有从其中心壳体延伸出的带螺纹的内套筒，套筒包围用于锁定件的内心轴。提供内部的玫瑰和手柄组件，玫瑰有向内的标签。螺母被拧到套筒上并且在其远离壳体的端部处具有间隔开的开口，每个开口逐渐地沿着顺时针方向逐渐靠近壳体的一系列台阶。每个步骤具有胎面和立管，使得当手柄被带到主轴上并且玫瑰被操纵以使得突出部配合到开口中并且玫瑰沿顺时针方向转动时，突片将接合最接近的立管住房门的厚度允许。玫瑰的进一步的顺时针转动将转动螺母并将螺母移动到更靠近壳体的位置，使得胎面接合突出部并且将玫瑰/手柄组件向内拉动并且将锁定件快速地安装在门上。
