摘要:
A vertical raising safety rail having a moveable top rail, a base, a movable center rail assembly positioned above the base and below the top rail, a drive shaft, and a motor that provides rotational power to the drive shaft. The safety rail further includes a pair of spaced apart lower linkage arm assemblies that is operatively connected to the base and to the center rail assembly and configured to raise or lower the center rail assembly relative to the base when a rotational force is applied to the drive shaft. The safety rail also includes a pair of spaced apart upper linkage arm assemblies that is operably connected to the center rail assembly and to the top rail. The upper linkage arm assemblies are operably connected to corresponding lower linkage assemblies and are configured to move the upper rail relative to the center rail assembly. When the rotational force is reversed, the safety rail collapses into a compact footprint.
