  • Patent number: 11773606
    Abstract: 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.

  • Patent number: 11761216
    Abstract: 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.

  • Patent number: 11466462
    Abstract: The present disclosure relates systems and methods involving movable/adjustable guardrails. An example system includes at least one rotating mount having a lower weldment rotatably coupled to an upper weldment. The lower weldment is coupled to a walking surface. The system also includes a guardrail weldment coupled to the upper weldment of the at least one rotating mount. The system additionally includes an actuator configured to controllably adjust a configuration of the guardrail weldment between an extended configuration and a retracted configuration with respect to the walking surface. In some embodiments, the system could include a remote unit configured to control a position of the actuator. For example, the remote unit could include a wired remote controller having a user interface and at least one button.

  • Publication number: 20220018146
    Abstract: The present disclosure relates to systems and methods involving collapsible guardrails. An example system includes a top rail, a mid rail, an enclosure, and at least two posts. Each post includes an upper primary member, a lower primary member, an upper secondary member, and a lower secondary member. The upper primary member and the lower primary member are slidably coupled to at least one slot in the mid rail. The upper secondary member is rotatably coupled to the upper primary member and the lower secondary member is rotatably coupled to the lower primary member. The upper primary member is further coupled to the top rail and the lower primary member is coupled to the enclosure.
