摘要： A vertical raising safety rail with dual support structure for rail arm bearing. The safety rail includes lower linkage arm assemblies that are connected to a base and to a 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 upper linkage arm assemblies that are connected to the center rail assembly and to a top rail. The upper linkage arm assemblies are connected to corresponding lower linkage assemblies and are configured to move the top rail relative to the center rail assembly. When the top rail is raised, one or more safety curtains are unfurled from a take-up roller inside the top rail to provide a safety curtain in the vertical plane of the safety rail. Each rail arm assembly includes a dual support structure for supporting a bearing axle.

摘要： A locking mechanism associated with a handrail is provided. A housing having a top open end is configured to accommodate the handrail in an upright position. The housing has a side open end configured to accommodate the handrail in a collapsed position. A pair of slots is provided on opposite side surfaces of the housing. Each of the side surfaces is adjacent to the side open end. A bracket is affixed to any one of the side surface of the housing. A locking member is pivotally coupled to the bracket. The first arm of the locking member is configured to selectively engage with the pair of slots to retain the handrail in the upright position. A second arm of the locking member is configured to selectively release the first arm from the pair of slots to allow the handrail to move from the upright position to the collapsed position.

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 aim 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 safely rail collapses into a compact footprint.

摘要： The present invention is for a safety guard rail system having folding guard rails designed to be raised or lowered at their base by a single individual from an acceptable safe distance from the edge of a precipice, such as the edge of a building roof. A sliding sleeve hinge lock locks each folding rail in an erect position and can be remotely unlocked for folding the rail. An elongated grappling tool has a hook-like end for grabbing the sliding sleeve hinge lock handle for locking and unlocking the hinge lock from a distance when erecting or folding a guard rail.

摘要： A collapsible safety rail system for providing a portable or permanent protective barrier to provide for fall prevention from elevated or other work areas. Lockable pivot assemblies are located between heavy bases and the end posts of collapsible safety rail assemblies. Removable detent pins are utilized to lock the pivot assemblies to maintain the erected position of the collapsible safety rail assemblies in protective vertical orientation or are removed to allow maneuvering of the collapsible safety rail assemblies to a minimum viewable profile position when not required for personnel protection.

摘要： The present disclosure relates systems and methods involving movable/adjustable platforms and/or guardrails. An example system includes a bracket configured to be coupled to a fixed structure having a walking surface. The system also includes a flip door portion rotatably coupled to the bracket and a guardrail portion rotatably coupled to the flip door portion. The system includes a linkage further coupling the flip door portion to the guardrail portion. The system yet further includes an actuator configured to controllably adjust a configuration of the flip door portion, the linkage, and the guardrail portion between an extended configuration and a retracted configuration with respect to the walking surface.
