Abstract: Expanded structures are formed by cutting a series of concentric rings or sections from a single block or sheet of solid material. The "rings" need not be circular, but may be any regular or irregular geometric or other shape as desired, so long as they are substantially concentric with one another. The cuts are made so that they angle outwardly from the upper to the lower surface of the block or sheet, and pass completely through the sheet or block. This provides a series of concentric sections, with each section having a lower, outer periphery which is at least slightly larger than the upper, inner periphery of the next larger adjacent section. This allows each section to be stacked atop a larger adjacent section, with the lower outer edge surface of each smaller section resting upon the upper inner edge surface of the larger section immediately therebelow.

Abstract: A plumbing assembly is provided which is formed from a plurality of rigid pipe sections, connected between a movable sink and a relatively fixed fluid outlet. These pipe sections are joined together by swivel fittings that permit the pipe sections to rotate with respect to each other. In this manner, different distances between the sink and the fluid outlet are accommodated by a folding and unfolding motion of the plumbing assembly in a minimum of space behind the wall of an expandable portion of the room. Fluid supply lines for providing hot and cold water to the sink faucet can be mounted within the same spacial area by means of similar swivel fittings that create an offset parallelogram structure. The lengths of at least the fluid draining pipe sections and the supporting structure behind the wall are selected such that a downward slope is maintained over the entire fluid flow path between the sink and the fluid outlet regardless of sink position during usage.

Abstract: A locking device which locks the slide-out room of mobile living quarters in the retracted position when the mobile living quarters is moved includes inner and outer tubular members which extend between parallel bulkheads on the main living area and the slide-out room. A handle is moved over center between latched and unlatched positions. In the latched position, the inner member is extended from the outer member to force the bulkheads apart, thereby causing a portion of the outer wall to slide-out room to engage the bulkhead on the main living area to affect sealing therebetween. In the unlatched position, the inner member is retracted into the outer member, thereby permitting removal of the locking device from the slide-out room.
