A guardrail for a scaffold, which has at least at one end a coupling section for coupling with a coupling element of a vertical post or vertical frame of the scaffold, wherein the coupling section is flat and is penetrated by an elongate opening which extends parallel to a longitudinal axis of the railing member and which has a constant width as far as an extension at the end.

A scaffold comprising a guardrail, a method for erecting a scaffold and a use of a guardrail.

The claimed invention relates to a folding utility scaffold that greatly reduces the space requirement for shipment when the utility scaffold is in the folded configuration while maintaining or increasing stability. The scaffold includes first and second ladder frames and a hinge assembly interconnecting the ladder frames. The scaffold comprises first and second ladder frames and a hinge assembly interconnecting the ladder frames. The hinge assembly enables movement of the scaffold between an unfolded configuration in which the ladder frames are spaced apart and a folded configuration in which the ladder frames are disposed side by side, i.e., with the ladder frames touching. The ladder frame and hinge assembly are designed to avoid interference between components of the hinge assembly and components of the ladder frame in the folded configuration so that the ladder frames can be disposed in side-by-side relation in the folded configuration.

In an example, a system is described. The system includes a guardrail having a post, and the post having a post dog. The system also includes a latch eye configured to be coupled to a flip door. The system also comprises a safety latch mechanism configured to be coupled to a fixed structure and including a body, a socket configured to receive the post, and a door latch rotatably coupled to the body and biased in a latched position that is configured to engage with the latch eye and thereby retain the flip door in a lowered position. Based on the post being inserted into the socket of the safety latch mechanism, the post dog engages with and rotates the door latch from the latched position to an unlatched position, thereby allowing the flip door to be raised from the lowered position to a raised position.

In an example, a system for preventing a flip door from being raised without a guardrail installed is disclosed. The system includes a guardrail having a post, and the post having a post dog. The system also includes a safety latch mechanism configured to be coupled to a fixed structure. The safety latch mechanism includes a body, a socket disposed in the body and configured to receive the post, and a door latch rotatably coupled to the body and biased in a latched position that is configured to retain a flip door in a lowered position. Based on the post being inserted into the socket of the safety latch mechanism, the post dog engages with and rotates the door latch from the latched position to an unlatched position, thereby allowing the flip door to be raised from the lowered position to a raised position.
