摘要： The handrail assembly includes at least one tubular metal stanchion, having a base and a hemispherical cap having a threaded receiver and at least a horizontal top rail. The horizontal top rail has an inner metal pipe, an outer plastic pipe, and at least one aperture for receiving the metal stanchion. Prior to assemblage, a threaded fastener is attached to the interior of the inner metal pipe opposite the aperture. In an alternative embodiment, the hemispherical cap on the stanchion is replaced by a threaded fastener and a threaded nut is positioned within the interior of the inner metal pipe opposite the aperture. Prior to insertion of the stanchion into the aperture, at least one tubular plastic sheath, having a first end conforming with the base of the stanchion and a second end conforming with the top horizontal rail, is slipped onto the tubular metal stanchion. Following placement of the top horizontal rail atop the stanchion, the sheath rests on the base of the stanchion and engages the top horizontal rail. The top horizontal rail is locked in position atop the stanchion by threading the threaded receiver and the threaded fastener together. Disassemblage of the handrail assembly is facilitated by the easy unthreading of the threaded receiver and the threaded fastener.

摘要翻译： 扶手组件包括至少一个管状金属支柱，其具有基部和具有螺纹接收器和至少水平顶部导轨的半球形帽。 水平顶部轨道具有内部金属管，外部塑料管和用于接收金属支柱的至少一个孔。 在组装之前，螺纹紧固件附接到与孔相对的内金属管的内部。 在替代实施例中，支柱上的半球形盖被螺纹紧固件代替，并且螺母位于内孔金属管的与孔相对的内部。 在将支柱插入孔内之前，具有与支柱基部相符的第一端和符合顶部水平导轨的第二端的至少一个管状塑料护套滑动到管状金属支柱上。 在顶部水平导轨放置在支柱顶部之后，护套位于支柱的底部，并与顶部水平导轨接合。 顶部水平导轨通过将螺纹接收器和螺纹紧固件拧在一起而被锁定在支柱顶部的位置。 通过螺纹接收器和螺纹紧固件的容易的脱螺纹来促进扶手组件的拆卸。

摘要： The guardrail assembly includes at least one tubular metal stanchion, having a base and an extendable/retractable setscrew, and at least a horizontal top rail. The horizontal top rail has an inner metal pipe, an outer plastic pipe, and at least one aperture for receiving the metal stanchion. Prior to assemblage, the setscrew is retracted inside the tubular stanchion. Prior to insertion of the stanchion into the aperture, at least one tubular plastic sheath, having a first end conforming with the base of the stanchion and a second end conforming with the top horizontal rail, is slipped onto the tubular metal stanchion. Following placement of the top horizontal rail atop the stanchion, the sheath rests on the base of the stanchion and engages the top horizontal rail. The top of the stanchion or the sheath are capable of supporting the top horizontal rail. The top horizontal rail is locked in position atop the stanchion by extension of the setscrew. Disassemblage of the guardrail assembly is facilitated by the easily retracted setscrew.
