Abstract: A motor home seat lift apparatus is provided which is located within the vehicle at the front passenger door, which is foldable to a storage location adjacent to the dashboard and forward of the front passenger seat, and which unfolds for usage to place a lift seat adjacent to the level of the front passenger seat, from which a user can slide onto (or off of) the lift seat. The lift seat is then movable from the that level, downward and outward through the opened front passenger door, to a level comfortably adjacent the ground level, for the user to then stand upon when exiting the lift seat. In general, the apparatus includes a lift seat which moves laterally within the vehicle into and out of the door, and rotates up and down between the exterior ground level and the passenger seat level, above the passenger compartment floor.

Abstract: A joint is connected between floors of a vehicle that are movable relative to each other. The joint includes a plurality of hinged segments to accommodate vertical and longitudinal relative motion between the floors. At least one of the hinged segments includes a flat, walkable surface aligned with the floors.

Abstract: A table or similar structure is provided having an expandable surface area arrangement where the usable or working surface area is retractable into and out of a housing along a curvilinear path that includes both horizontal and vertical components and wherein weight compensating structure is provided to offset the impact of vertical movement of the surface area. The usable surface is formed from an array of adjacent panels connected by a backing web which allows them to lie flush together when the surface area is retracted for use and to separate as needed to follow the curvilinear path when retracted into the housing for storage. The extent of movement into and out of the housing is variable according to the amount of surface area required in a given instance. When implemented into a dining table, for example, vertical support legs for one end of the table can be attached to the end panel of the surface area which is first withdrawn from the housing.

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: An expandable room structure is provided having relatively movable room portions supported by telescopically sliding tubes, at least one of those tubes being movable also laterally to pivot as the room portion floors slide into the same horizontal plane when the room structure is moving into expanded positions. In retracted positions the room portion floors are vertically spaced to permit one room portion to nest within the other. A rack and pinion drive arrangement is provided to cause relative movement between the tubes. Selective lateral movement of one of the tubes is permitted by engagement with an adjustably inclined surface extending out of the other tube such that the laterally moving tube pivots about the pinion to a desired degree. A ramp surface is formed on the abutting edge of the floor of one room portion, and the abutting edge of the floor of the other room portion moves up and down that ramp portion when transitioning between expanded and retracted positions.

Abstract: A combination stop and latch for a door. The latch is swingably carried within the door or structure side wall with the stop secured to the other of the door or side wall. The latch automatically swings into an extended position projecting from the door or side wall as the door is opened for engagement with the stop.
