Abstract

A recreational vehicle includes a lower body and a vertically telescoping upper body. The upper body includes a second floor, fully suspended when the upper body is raised, and resting on stops when the upper body is lowered. A lift mechanism includes a take up drum, lift line, and pulley system to raise and lower the upper body including the upper portion of the telescopic elevator shaft while telescoping corner posts support and guide its motion. A elevator has bottom and top floors connected by vertical columns and a lift cable extending from the base of each column through top and bottom pulleys of an adjacent corner post to a power take up drum to raise and lower the elevator. A vertically movable bathroom is similarly provided.

Claims

1. A two-story recreational vehicle including:

a lower body with a lower floor and stationary sidewalls, a vertically movable upper body consisting of the roof, descending sidewalls and an upper floor, said upper floor being suspended by cables or chains from said roof and positioned directly above the lower floor and travelling within the lower floor'"'"'s sidewalls;

said upper floor being level and fully suspended when the roof is raised and adapted to rest on stops or furniture when said upper body is lowered, thereby functioning as a floating floor.

2. A two-story recreational vehicle as defined in claim 1, said upper floor comprising a plurality of independent sections, each section being suspended from said roof by cables and coming to a stop at various levels as necessitated by the lay-out of the first floor furniture when said upper body is lowered, thereby functioning as a multiple section floating floor.

3. A two-story recreational vehicle, including:

a lower body with a lower floor and stationary sidewalls;

a vertically movable upper body with a roof and descending sidewalls and an upper floor suspended from said roof, said upper floor being fully suspended when said upper body is raised,and adapted to rest on stops when said upper body is lowered;

vertical corner posts extending between said lower and upper floors and supporting wall panels between them, said corner posts each including a pipe with bottom and top pulleys thereon, and a central shaft adapted to telescope upward with vertically movable wall panels; and

an elevator having bottom and top floors connected by vertical columns, and a lift cable extending from the base of each said column through top and bottom pulleys of an adjacent corner post to a take up drum to raise and lower said elevator.

4. A two story recreational vehicle as defined in claim 3, further including a room having bottom and top floors connected by vertical columns, and a lift cable extending from the base of each said column through top and bottom pulleys of an adjacent corner post to a take up drum to raise and lower said room.

5. A two story recreational vehicle, including:

a lower body with a lower floor and stationary sidewalls;

a vertically movable upper body with a roof and descending sidewalls and an upper floor suspended from said roof, said upper floor being fully suspended when said upper body is raised, and adapted to rest on stops when said upper body is lowered;

a lift mechanism for said upper body, including a drive means and integral take up drum, a first pulley at the base of said stationary sidewall, a second pulley at the top of said stationary sidewall, and a lift line extending from said take up drum through said first and second pulleys to said upper body to raise and lower said upper body relative to said lower body;

vertical corner posts extending between said lower and upper floors and supporting wall panels between them, said corner posts each including a pipe with bottom and top pulleys thereon, and a central shaft adapted to telescope upward with vertically movable wall panels; and

an elevator having bottom and top floors connected by vertical columns, and a lift cable extending from the base of each said column through top and bottom pulleys of an adjacent corner post to a take up drum to raise and lower said elevator.

6. A two-story recreational vehicle as defined in claim 5, further including a room having bottom and top floors connected by vertical columns, and a lift cable extending from the base of each said column through top and bottom pulleys of an adjacent corner post to a take up drum to raise and lower said room.

7. A two-story recreational vehicle as defined in claim 5, said upper floor comprising a plurality of independent sections suspended from said roof.
