ABSTRACT:
The invention provides a stowable ladder mechanism for an overhead bed or upper berth in a bunk bed. A horizontal linear guide is vertically spaced above a horizontal support surface and associated with a bed or berth. The rungs of the ladder are supported between two vertical uprights, one of which is fixed at one end of the berth and the second of which is coupled to the horizontal linear guide and translates across the horizontal support surface along one side of the bed. The plurality of rungs include swing sections mounted on hinges which hang vertically when the translatable vertical upright is positioned adjacent to the fixed vertical upright. When the translatable upright is positioned away from the fixed upright, the swing sections are supported in a horizontal position.
