Rotatable building structure
A rotatable building structure contains a vertical central core for supporting suspended floor units surrounding the core. An annular platform extends from the core at corresponding floor units for providing accessibility to and from the central core. The floor units contain a drive mechanism for rotational displacement. A wind tool deployable from the floor unit provides alternative wind power assist for rotating the floor units.

CONTEXT OF THE INVENTION1. Field of the Invention
This invention relates to static structures and especially to a structure mounted for in situ repositioning.
In particular, the structure of this invention concerns a building having floor units that are rotatable about a vertical axis.
2. Background Information
The ability of an apartment to command a desirable view is a recognizable factor in determining the salability and economic value of the apartment. However, most buildings have only a limited number of apartments with highly desirable exposures. A solution to this problem is to provide a changeable environment by in situ repositioning of the building. Typically, repositionable building structures were designed with an outer casing rotatably mounted on a spindle; the structures were used principally for observation towers, amusement devices, and/or restaurants for providing patrons with changeable views and not for apartment, hotel and similar dwellings; examples of such structures are shown in U.S. Pat. Nos. 3,905,166, 6,742,308, and 841,468.
A limitation of these structures is that they are not intended primarily for use as multi-story apartment buildings or hotels or for providing selective 360° viewing capability. Another shortcoming is that lack of floor independence decreases load stability.
BRIEF SUMMARY OF THE INVENTIONBriefly, the nature of this invention involves a building structure having a vertically disposed central core with plural horizontal floor units suspended from and surrounding the core at incremental heights for transferring balanced vertical loading through the core. An annular platform extending horizontally from the core, in correspondence with the floor units, provides a corridor for accessing the central core. The floor units are independently displaceable about the core, for example, by motor-power actuation, wind-power, electro-magnetic energy, or other drive force.
In view of the foregoing, it should be apparent that the present invention overcomes the limitations of the prior art and provides an improved rotatable building structure.
Having thus summarized the invention, it will be seen that it is an object thereof to provide a rotatable building structure of the general character described herein which is not subject to any of the aforementioned limitations.
Another object of this invention is to provide a rotatable building structure suitable for high-rise or low-rise buildings.
A further object of this invention is to provide a rotatable building structure with independently rotatable suspended floor units that provide improved seismic stability.
A still further object of this invention is to provide a rotatable building structure wherein the configuration of the floor units can optionally be varied in shape such that the profile of the building will continually change during rotation of the floor units.
Still another object of this invention is to provide a rotatable building structure including a stationary platform providing an accessway from the floor unit to the central core.
Yet another object of this invention is to provide a rotatable building structure having single or multiple vertical cores for supporting the floor units.
Still yet another object of this invention is to provide a rotatable building structure wherein displacement of the floor units are computer-controlled and actuatable on command.
Yet still a further object of this invention is to provide a rotatable building structure having prefabricated furnished floor units to facilitate erection and onsite installation.
Yet still another object of this invention is to provide a rotatable building structure with aerodynamically designed floor units that can be repositioned to reduce wind load, as in a hurricane.
Other objects of this invention will in part be apparent and in part will be pointed out hereinafter.
With these ends in view, the invention finds embodiment in certain combinations of elements and arrangements of parts by which the aforementioned objects and certain other objects are hereinafter attained, as more fully described with reference to the accompanying drawings and the scope of which is more particularly pointed out and indicated in the appended claims.
BRIEF DESCRIPTION OF THE DRAWINGSIn the accompanying drawings, in which are shown an exemplary embodiments of the invention:
With specific reference now to the figures in detail, it is stressed that the particulars shown are by way of example and for the purposes of illustrative discussion of the preferred embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt has been made to show aspects of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken together with the drawings should make it apparent to those skilled in the art how the several forms of the invention may be embodied in practice.
Referring now in detail to
Referring next to
The mechanical/electrical components such as an elevator shaft 16, an emergency stairway 18; HVAC, water supply systems, trash disposal, electrical power cables, and utilities, such as, telephone, computer, television, jointly designated 20, are housed within the central core 14. It should also be noted that the core 14 has an opening (not shown) to provide a passageway from the platform 22 to the interior of the core 14, for example, for occupants to access the elevator shaft 16.
As further noted in
Concerning next the securement of the floor units 20 to the central core 14, there is provided an upper rail 26 and a lower rail 28, as shown in
Although the floor unit 12 has been described as defining a circular periphery surrounding the core 14, alternative floor unit configurations e.g. square, ellipsoid, or non-symmetric shapes are within the scope of this invention, and will provide a continually changeable building profile during displacement. It should also be noted that the radial dimension of the floor units 12 can be varied, for example, from floor level to floor level, so as to create a variable building profile. Additionally, the exterior boundary wall 24 can be aerodynamically designed and selectively positionable for reducing wind load, especially during hurricanes.
It is also within the scope of this invention to employ prefabricated floor units 12, with the respective unit containing factory-furnished interiors of an apartment, a hotel room, an office space, such as partition walls, floors, mechanical equipment, HVAC, plumbing connections, electrical connections, and the like.
In an alternate embodiment, wherein the same reference numerals have been used for designating corresponding parts of the previously described embodiment with the suffix “a”, a floor unit 12a is connected to a central core 14a in a manner as described herein (see
In a further alternate embodiment as shown in
It should further be apparent that since the independent floor units 12 at each floor level are each separated, for example, as noted in
It should thus be seen that there is provided a rotatable building structure which achieves the various objects of this invention and which is well adapted to meet conditions of practical use.
Since various possible embodiments might be made of the present invention or modifications might be made to the exemplary embodiments above set forth, it is to be understood that all materials shown and described in the accompanying drawings are to be interpreted as illustrative and not in a limiting sense.
