Abstract
Abstract A two level berth structure for use on ships, in railroad cars or the like wherein space is at a premium including a counter balanced upper bunk mounted upon track means at opposite ends whereby the berth may be easily moved from a relatively horizontal position whereat it is locked for sleeping to an inclined position having one side adjacent the top of the lower bunk at a location comfortable for sitting upon the lower bunk and resting your back against the upper bunk. The structure includes the end walls for both the upper and lower bunk and has within the end walls weights to counterbalance the weight of the upper bunk during movement from one location to another.
