[0001] This invention relates to stalic structures and especially to a structure mounted
for in situ repositioning.
[0002] In particular, the structure of this invention concerns a building having floor units
that are rotatable about a vertical axis.
[0003] The ability of an apartment to command a desirable view is a recognizable factor
in determining the saleability 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
will changeable views and not for apartment, hotel and similar dwellings; examples
of such structures are shown in
U.S. Patent Nos. 3, 905, 166,
6, 742, 308, and
841, 468.
[0004] 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 deg. viewing
capability. Another shortcoming is that lack of floor independence decreases load
stability. It is also known from documents
DE 2318203 and
DE 1949254 rotatable building structures containing 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. 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.
[0005] Another object of this invention is to provide a rotatable building structure suitable
for high-rise or low-rise buildings.
[0006] A further object of this invention is to provide a rotatable building structure with
independently rotatable suspended floor units that provide improved seismic stability.
[0007] 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.
[0008] 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.
[0009] Yet another object of this invention is to provide a rotatable building structure
having single or multiple vertical cores for supporting the floor units.
[0010] 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.
[0011] 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.
[0012] 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.
[0013] Other objects of this invention will in part be apparent and in part will be pointed
out hereinafter.
[0014] Briefly, 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, electromagnetic energy, or other drive force.
[0015] 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.
[0016] 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.

[0018] 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.
[0019] Referring now in detail to FIG. 1 of the drawings, there is shown a portion of a
multi-level rotatable building structure 10 having an independently rotatable suspended
floor unit 12. It should be understood that the structure of this invention encompasses
application to high-rise and/or low-rise buildings. The arrows are intended to show
that each of several floor units 12 can rotate in opposite circular directions or
optionally can rotate in the same circular direction. The floor units can also operate
at different speeds.
[0020] Referring next to FIG. 2, there is shown in plan view of a central core 14, preferably
cylindrical in shape, and constructed of reinforced concrete, structural steel or
equivalent materials. A platform 22 is attached to or formed integrally with the central
core 14. The core 14 is designed to support the total live and dead load of the floor
units 12. The floor units 12 surround the core 14 and provide for balanced load transfer
to the core 14. The floor units 12 can be nonuniform shapes and/or mounted asymmetrically
with respect to the central core 14, as for example, is shown in FIG. 8, with a counterweight
applied to achieve balanced loading. It should be noted that this later arrangement
of floor units 12 will provide a variable building profile during rotation. As will
be further noted, the floor units 12 can be connected along a horizontal plane to
form floor levels at incremental vertical heights along the central core 14 and are
supported in cantilever fashion from the central core 14. In the event of seismic
loading, the free ends of the respective floor units 12 may be subjected to movement
without resulting in stress fracture, as may be the case if the separate floor levels
were interconnected. 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.
[0021] As further noted in FIG. 3, in this preferred embodiment, the floor unit 12 is substantially
a wedge-shaped, open-frame segment that is preferably fabricated of structural steel,
aluminum, a combination of the above, however, other materials may be suitably utilized.
A plurality of connected floor units 12 are designed to encircle the core 14 to provide
a circular periphery. A roof member 21 and a floor member 23 are secured to the frame
segment to form an enclosure. Note that a portion of the floor member 23 as shown
in FIG. 3 has been displaced to better illustrate the connection to the core 14. The
floor unit 12 also has a peripheral exterior curved boundary wall 24, preferably made
of a transparent material, for providing maximum visibility from within the floor
unit 12 and an interior boundary wall (not shown) adjacent the platform 22 with an
occupant passageway through the interior boundary wall for accessing the platform
22.
[0022] 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 FIGS. 3, 4 and 5, designed
for supporting the floor unit 12. With regard to rotational displacement of the floor
unit 12, a roller bearing 30 is mounted to a distal end of an arm 27 extending from
the roof member 21. The roller bearing 30 is adapted to ride within a raceway 32 defined
by the upper rail 26. A safety lock 34, also extending from the arm 27, is positionable
below the raceway 32 for securing the roller bearing 30 in the raceway 32. Another
raceway 36 is defined in the lower rail 28 and is adapted to accommodating a drive
wheel 38. The drive wheel 38 is actuated by an electric motor 40 mechanically linked
to the drive wheel 38 by a beveled gear arrangement 42 or by other drive force. The
gear ratio can be designed to the operating specifications. The motor drive 40 can
also be computer operated by command at selected speeds and directions for displacing
the floor unit 12 in either a clockwise or counterclockwise direction. 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.
[0023] 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.
[0024] 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 FIG. 6). In this embodiment, a wind tool 46 is shown deployed for providing
a wind-power assist to the previously discussed motor drive. The wind tool 46 is comprised
of a planar vane 48 hingedly connected to a spindle 50 mounted to a peripheral wall
24a of the floor unit 12a. The vane 48 can be remotely and/or directly actuated for
deployment to an operational mode from a retracted mode housed within the floor unit
12a. A bar 52 provides a rotational limit stop to prevent further rotation of the
vane 48 when in the fully deployed position. The wind tool 46 can alternatively be
used for electrical power generation, for example, for recharging a backup battery
system.
[0025] In a further alternate embodiment as shown in FIG. 7 wherein the same reference numerals
have been used for designating corresponding parts of the previously described embodiment
with the suffix "b", a floor unit 12b is connected to a central core 14b by a tension
cable or steel strut 26b. A slidable anchor bearing 30b is attached at a distal end
of the strut 26b. The anchor bearing 30b is contained within a slot 32b. The slot
32b extends on a horizontal plane, around the circumference of the central core 14b.
The strut 26b is designed to support the floor unit 12b. A modified platform 22b projects
under a portion of the floor unit 26b to provide additional support thereto and further
includes a roller bearing 38b mounted in a track (not shown) or equivalent slide means
for permitting displacement of the floor unit 26b along the platform 22b.
[0026] It should further be apparent that since the independent floor units 12 at each floor
level are each separated, for example, as noted in FIG. 1, any seismic force transmitted
through the central core 14 would tend to be absorbed, in contrast to conventionally
interconnected floors, and thus less likely to be subject the floor units 12 to stress
failure. Also the aerodynamically designed and repositionable boundary wall 24 of
the floor units 12 and the opening spacing between respective horizontal levels of
floor units 12, substantially reduce the wind load applied as compared to a conventional
vertical wall structure. 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.
