摘要： A self-leveling sign hanging device having a housing hung from the structural support members of suspended ceilings. A cable is stored in the housing on a wind up reel. A spring applies a force to the reel to wind the cable on the reel. The cable exits and returns to the housing forming a loop. At the bottom of the loop is a tubular bracket from which the sign is hung. The cable freely passes through the tubular bracket which allows the tubular bracket to remain horizontally level. Stops are mounted on the cable to restrict the length of cable wound onto the reel thus defining the height that the sign hangs above the floor.

摘要： An apparatus and method for providing a retractable self-leveling ceiling sign hanger. The apparatus comprises of a sign housing having an upper housing and a lower housing, a cord reel housing, and a cord that forms a continuous loop between the sign housing and the cord reel housing. The sign housing and the cord reel housing coact to transfer or extend cord between them to thereby raise and lower the lower housing in a level position for installing, changing, and hanging a sign. The sign housing utilizes roller assemblies and a cord lock mechanism. The cord reel housing utilizes a handle, a tool, a locking means, and a cord retracting means for moving the cord reel housing and transferring or extending cord to and from the cord reel housing. Magnets are also provided to affix the cord reel housing to the upper housing of the ceiling sign hanger.
摘要翻译：一种用于提供可伸缩自平整吊顶吊架的装置和方法。该装置包括具有上壳体和下壳体的标志壳体，绳索卷轴壳体和在标志壳体和绳索卷轴壳体之间形成连续环路的绳索。标志外壳和电缆卷轴壳体共同转移或延伸它们之间的电缆，从而将下壳体升高和降低在用于安装，改变和悬挂标志的水平位置。标志外壳使用滚轮组件和绳索锁定机构。绳索卷轴壳体利用手柄，工具，锁定装置和绳索缩回装置，用于移动绳索卷轴壳体并将绳索传送或延伸到绳索卷轴壳体和从绳索卷轴壳体延伸。还提供磁铁将电缆卷轴外壳固定在天花板吊牌的上部外壳上。
