Abstract: A retractable bunk or bed is disclosed. The retractable bunk can be used in a sleeper compartment so as to optimize space within the cab. The innovation can include a shaft around which a suitably strong, yet flexible, material bunk can be wound. Thus, in a closed or “hidden” state, the material can be rolled up around the shaft and stowed, for example behind a door or within a compartment as desired. In an open position, the material is extended in a horizontal manner and affixed to retain the “bunk” position.

The hook is hooked to the rim of a positioning plate of the bedpost so that there is no gap left between the bedposts and the mesh structure.

Abstract: A portable, suspendable cot used in rock climbing and the like includes a collapsible frame supporting a webbing therebetween. The frame includes linkages that pivot from a parallel orientation in a closed position to an orthogonal angle (for rectangular frames) or an acute angle (for trapezoidal frames) in an open position. The linkages further comprise couplings that complete the framework and use gravitational forces to enhance the linkages, forming a secure platform that resists warping. Cabling connects the respective linkages and supports the frame so as to be suspendable from a central apex vertically displaced from the frame. The cabling can pass through a free end of the pivoting links to guide the free end to the coupling, and preserve a closed loop for the respective elements of the frame.
