Abstract
Abstract A rotatable structure supported upon a stationary base. Bearing means support the rotatable structure which structure includes a central core structure supported by one of the bearing races. The inner ends of radially disposed floor and roof trusses are supported by the core structure in a manner avoiding undesirable radial loading of the bearing races. Upright tension rods interconnect the outer end segments of the floor and roof trusses with relative movement permitted between the trusses and the rod ends to accomplish the transfer of floor loads to the rigid roof structure thereby avoiding radial loads to the bearing races. A cylindrical access housing of the building structure extends centrally downward through the bearing races and may be provided with an elevator or stairway for a building entrance.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
251 words
A rotatable building structure supported by a stationary base including rigid support means, said building comprising in combination, a floor structure including radially disposed trusses, a roof structure including radially disposed trusses, tension rods extending intermediate said floor and roof structures interconnecting outer end segments of the roof and floor trusses, means coupling the tension rod ends to the floor and roof trusses in a manner permitting limited arcuate movement therebetween to facilitate the transfer of floor loads to the roof structure, an upright core structure centrally located within the building structure supporting the inner ends of said floor and roof structures, the inner ends of the floor trusses being supported by said core structure in a manner permitting floor loads to be carried by said tension rods, bearing means including inner and outer races relative to the rotational axis of the building and cooperatively supporting the rotatable building structure with one of said races associated with said core structure and the inner ends of the radially disposed floor trusses, said tension rods serving to transfer floor loads to the rigid roof structure whereby the transferred loads will result in downward axial loads on said core structure and said bearing means while subsantially avoiding the undesirable imparting of radial loads to the bearing means by the floor structure, and an access housing depending from and rotatable with the core structure, said access housing projecting through the bearing races, said access housing permitting vertical ingress and egress from the rotatable building structure.
Claim 2
Dependent Claim
251 words
A rotatable building structure supported by a stationary base including rigid support means, said building comprising in combination, a floor structure including radially disposed trusses, a roof structure including radially disposed trusses, tension rods extending intermediate said floor and roof structures interconnecting outer end segments of the roof and floor trusses, means coupling the tension rod ends to the floor and roof trusses in a manner permitting limited arcuate movement therebetween to facilitate the transfer of floor loads to the roof structure, an upright core structure centrally located within the building structure supporting the inner ends of said floor and roof structures, the inner ends of the floor trusses being supported by said core structure in a manner permitting floor loads to be carried by said tension rods, bearing means including inner and outer races relative to the rotational axis of the building and cooperatively supporting the rotatable building structure with one of said races associated with said core structure and the inner ends of the radially disposed floor trusses, said tension rods serving to transfer floor loads to the rigid roof structure whereby the transferred loads will result in downward axial loads on said core structure and said bearing means while subsantially avoiding the undesirable imparting of radial loads to the bearing means by the floor structure, and an access housing depending from and rotatable with the core structure, said access housing projecting through the bearing races, said access housing permitting vertical ingress and egress from the rotatable building structure.
Claim 3
Dependent Claim
18 words
The building structure as claimed in claim 1 wherein said access housing additionally serves to carry service conduits.
Claim 4
Dependent Claim
23 words
The building structure as claimed in claim 2 additionally including a services coupling disposed below and in axial alignment with said access housing.
Claim 5
Dependent Claim
48 words
The building structure as claimed in claim 1 additionally including a stationary ring gear associated with one of said bearing races, a motor mounted within the rotatable access housing, a powered pinion driven by said motor and enmeshed with said ring gear imparting rotation to the building structure.
Claim 6
Dependent Claim
103 words
The building structure as claimed in claim 1 wherein said upright core structure includes a circular wall structure above said bearing means concentric with the rotational axis of the building structure, said wall structure having a passageway therein for entry into the living area of the structure, said core structure additionally including a framework above said wall structure comprised of vertical and inclined struts serving to support the inner ends of the roof trusses whereby loads imparted to said trusses are translated into loads exerted along vectors oriented lengthwise of the core structure ultimately resulting in axially directed loads on said bearing means.
Claim 7
Dependent Claim
43 words
The building structure as claimed in claim 1 wherein the floor trusses include upper and lower chords, an annular plate of the core structure serving to mount the innermost ends of the upper chords of the floor trusses and the outer bearing race.
Claim 8
Dependent Claim
54 words
The building structure as claimed in claim 6 wherein said access housing is supported by said annular plate, resilient means interposed between said access housing and said plate to permit slight relative movement therebetween during rotation of the housing to assure coaxial rotation of the housing with the rotational axis of the building structure.
Claim 9
Dependent Claim
56 words
The building structure as claimed in claim 7 wherein series of interchangeable spacer elements are disposed about the bearing races, said elements being replaceable by elements of differing vertical dimensions to permit leveling of the rotational building structure for purposes of true coaxial rotation of the access Housing with the remaining portion of the building structure.
