The present disclosure relates systems and methods involving movable/adjustable guardrails. An example system includes a frame weldment and a rail assembly attached to the frame weldment. The rail assembly includes a first post and a second post. The base portion of the first post is rotatably coupled to a first pivot point of the frame weldment and the base portion of the second post is rotatably coupled to a second pivot point of the frame weldment. The system also includes a top rail rotatably coupled between a top portion of the first post and a top portion of the second post. The system yet further includes an actuator configured to controllably adjust a configuration of the rail assembly between an extended configuration and a retracted configuration with respect to the frame weldment.

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.

Vertically raising safety rail with dual curtain assembly
10724257 · 2020-07-28 · ·

A vertical raising safety rail. 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.

A collapsible barrier includes a substantially rectangular sheet. The substantially rectangular sheet includes a first post and a second post pivotably connected with hinges. Feet with apertures configured to receive fasteners perpendicularly extend from the bottom of the first post and the second post. A first-bracing member and a second-bracing member respectively reinforce the first post and the second post in a perpendicularly oriented position with respect to each other. A metallic webbing integrated with the substantially rectangular sheet to provide suitable strength and load bearing capabilities. The substantially rectangular sheet includes a perpendicular lip along the vertical edges. The posts are configured to pivot the feet to align parallel with the substantially rectangular sheet. When the feet are aligned parallel with the substantially rectangular sheet the lip of the substantially rectangular sheet allows multiple collapsible barriers to be stacked. The collapsible barrier is useful for providing a portable barrier.
