  • Patent number: 11667241
    Abstract: A foldable guardrail assembly is provided for selectively facilitating access to a machine component located onboard a vehicle. The vehicle has a platform with a handrail disposed thereon and located adjacent to the machine component. The guardrail assembly includes a set of guardrails pivotally connected to each other in a successive manner via at least a corresponding number of hinge assemblies. A first one of the guardrails is pivotally connected to an upright portion of the handrail via a first hinge assembly. The guardrail assembly further includes a first latch assembly provided, at least in part, on a last one of the guardrails. The first latch assembly is configured to releasably secure the last one of guardrails to the platform when the guardrails operably move into in a fully unfolded position, via the hinge assemblies, for providing access to the machine component located onboard the platform.

  • Patent number: 9487145
    Abstract: A locking mechanism associated with a handrail is provided. 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. On exerting a force in an upward direction on a second arm of the locking member the first arm is selectively released from the pair of slots to allow the handrail to move from an upright position to a collapsed position.
