Description
PRIORITY
[0001] Pursuant to 35 U.S.C. 119(e) and 37 C.F.R. 1.78, the present
application claims priority to the provisional application entitled
"Rotatable Storage with Alternatively Accessible Sides" Application
No. 60/482,048, filed on Jun. 24, 2003, the inventor of which is
William Jefferson Stone III.
FIELD OF THE INVENTION
[0002] The present invention relates generally to rotating storage
structures that are used for supporting, holding and safekeeping
objects. More particularly, the present invention relates to a
reversing storage cabinet.
BACKGROUND
[0003] A typical structure, such as a cabinet, furniture, et
cetera, may contain rotatable unit(s), for example, a cabinet may
have a "lazy Susan" tray. These rotatable units have widespread
applications from cabinetry design to sophisticated high precision
equipment. There are a number of commercially available designs
with regard to rotatable units within a structure on the
market.
[0004] There are storage cabinets known in the prior art that
rotate around an axis. For example, the storage cabinet described
in U.S. Pat. No. 6,273,531 by Scheffer (2001) is located on the top
of a desk and can be rotated around an axis. By rotating the
cabinet around an axis one can alternatively access articles
located on different sides of the cabinet. Other examples having
similar designs are also described in various references, such as
U.S. Pat. No. 4,610,492 by Molander et al (1986), U.S. Pat. No.
5,651,595 by Willis (1997) and U.S. Pat. No. 5,487,599 by Weisburn
et al (1996).
[0005] There are disadvantages associated with these conventional
designs. For example, the first disadvantage is loss of space
because these conventional designs require significant space around
the rotating object so that it can perform a rotation around an
axis. Space loss in the front of the cabinet can typically be seen
as temporary loss because the space is lost only when the cabinet
is rotating. The space loss, however, is more wasteful when space
is lost behind the cabinet. Space loss behind a cabinet is
typically considered permanent loss of space because such space has
no practical utilization or compensation temporary or XXX. Such
permanent loss of space is illustrated in various conventional
designs, such as those described in U.S. Pat. No. 4,610492 by
Molander et al (1986) and U.S. Pat. No. 6,273,531 by Scheffer
(2001).
[0006] Another conventional design for rotating an object within a
structure uses non-obstructive rotation. To provide non-obstructive
rotation of an object or cabinet, it is permanently moved forward
away from a wall or other structure. A drawback associated with
this design is space loss in front of the cabinet. This type of
space loss can become a serious problem if space is at premium.
[0007] A second disadvantage associated with some conventional
designs is lack of exclusive access. Conventional designs do not
typically offer exclusive accessibility to one side of the storage
cabinet while other sides of the cabinet are not accessible. This
is not suitable when alternative access to different sides is
needed. Examples of these situations are the cabinets in which one
of the cabinet sides is used for jewelry or expensive collectibles
while another side of the cabinet stores firearms, etc. In order to
resolve this problem, conventional designs offer some designs
including special enclosures and shields as such those described in
U.S. Pat. No. 4,610492 by Molander et al (1986). However, providing
special enclosures and/or shields as solutions are typically
impractical in terms of convenience or cost, e.g. when storage
cabinet is used for relatively large articles (books, TV sets,
etc.).
[0008] A problem associated with the above-referenced designs is
safety. For example, if the weight of stored articles in a cabinet
is greater then the weight of the cabinet itself, the loaded
cabinet can become heavy and cumbersome to rotate and may also
create safety issues because it could tip over if it is not
supported from the top. However, providing support from the top may
increase the complexity and bulkiness of such designs and may also
increase the total cost of the storage cabinet.
[0009] As mentioned, the problem in these conventional designs is
waste of space. In the case of a bookcase in which the bookcase has
two storage sides for accessing stored articles waste of space is
significant in conventional rotating designs. To solve the problem
of waste of space, a known solution employs a cam system including
cam followers and grooves to resolve the problem of waste of
permanent space behind a shelf in a cabinet as described in U.S.
Pat. No. 4,124,262 by Schill (1978).
[0010] The disclosed cam system can reduce extra space needed for
rotation. In other words, with application of the disclosed cam
system, the rotating shelf within the cabinet does not require a
big clearance for rotation. When rotation is needed, the center of
the shelf is moved forward on its two (top and bottom) centered cam
followers sliding in the transverse grooves of the enclosure. A
pair of followers, mounted on opposite sides of the rotating shelf,
guideone side to the opposite side of the stationary enclosure. In
order for this rotation to perform correctly, these must be
accurate grooves in the enclosure.
[0011] Even though the cam system reduces the problem of space
waste, it generates new problems. For example, a problem associate
with the cam system is uneven loading of the cabinet weight. The
cam system loads the entire weight of the shelf with its content on
the bottom center cam follower. In addition to supporting the shelf
during the rotation, the bottom center cam follower also guides
itself along the transverse groove through out the enclosure. This
multi-functionality of the central bottom cam follower lowers the
reliability and lifetime of the cabinet.
[0012] Another problem associate with the disclosed cam system is
that upper and lower cam followers move independently of each other
in the guides. There is no guarantee that these guide will move
synchronously. Quite to the contrary, one cam always will tend to
move faster than another. This will happen for two reasons. First,
uneven weight distribution of the cabinet articles inside the
cabinet; and second, uneven pull or push of the shelf by the person
rotating the shelf Independent movement of the cam followers may
cause the cam followers to be jammed in the guides. Even if there
is no jam there is a high degree of wear and tear in the guiding
system, which shortens the lifetime of the cabinet.
[0013] The conventional design using a cam system with an upper
guiding system to support the cabinet in addition to the bottom
guiding system, as described in the U.S. Pat. No. 4,124,262, adds
an undesirable complication of the shelf design when the cabinet is
used for light loads and top support is not needed.
[0014] Another problem with the design of the cam system is that it
is dimension dependent. When dimensions of the cabinet are such
that it is not deep but wide, the center cam follower of the
cabinet is required to extend outside of the cabinet enclosure for
shelf rotation. This adds serious complications in the cabinet
design by requiring dynamic elongations to the guiding grooves of
the enclosure with telescoping guides. Also for heavy loaded
cabinets that are not deep but wide it is especially impractical
for reliability and safety concerns.
[0015] FIG. 1 of U.S. Pat. No. 4,124,262 also shows wasted space on
the left and right sides of the cabinet. In order to compensate for
some of this waste, the left and right sides of the shelf are of
cylindrically shaped. This design prevents two or more such
cabinets to be placed next to each other in close proximity without
wasted space. When the user has more than one cabinet it is
advantageous to place them next to each other without wasted space
for convenience of use and also for saving the total space
allocated for the cabinets.
[0016] What is needed, therefore, is a cabinet with alternatively
accessible sides that is economical in utilizing the space around
it, convenient for accessing different sides of this cabinet, has
some practical way of preventing access to side that are supposed
to be inaccessible at given time, is strong so it can handle heavy
loads using a reliable low wear mechanical arrangement for jam free
rotation and is simple in design and not expensive when handling
light loads.
SUMMARY OF THE INVENTION
[0017] The present invention comprises a compound movement link
mechanism that allows an object to move from the space it occupies
in one orientation and return to the same space in a different
orientation. Preferably the object is a support structure having at
least two selectively accessible sides. In a preferred embodiment,
the object is supported by a pair of synchronis compound movement
link mechanisms. Objectives of various aspects of the invention are
mentioned below.
[0018] In view of the above-stated disadvantages of the prior art,
objectives of the invention include providing an improved
rotational storage for applications where alternative access to
different sides of the cabinet is practical or needed.
[0019] Another objective of the invention is to provide a storage
cabinet that is economical in utilizing the space allocated for it.
In addition to be economical in utilizing the space around storage
the cabinet, its design should provide alternative of access to
different sides of the cabinet with convenience and ease.
[0020] A further objective of the invention is to provide limited
access to the side or sides of the cabinet that are not being
accessed at a given time. This secure access should be achieved
economically and with simplicity of design.
[0021] A still further objective of the invention is to provide a
storage cabinet that can be utilized for applications with heavy
loads such as for example storing books, firearms, electronic
equipment, etc.
[0022] Another objective of the invention is to provide a storage
cabinet that can be simple in design with low cost for light load
applications such as for example CD's, DVD's, stamp collections,
etc.
[0023] A reversable storage cabinet with alternatively accessible
sides, in one embodiment, includes a storage structure, which is
used to hold at least one article. Means for holding the storage
structure includes a four-link mechanism, wherein three of the
links are serially connected. The three serially connected links
are rotatably connected to two outside ends of a fourth link at two
substantially separated locations. The fourth link is substantially
stationary. The middle link of three serially connected links is a
part of the storage structure allowing reorientation of the storage
structure relative to the fourth stationary link for alternative
access to the sides of storage cabinet.
[0024] Additional features and benefits of the present invention
will become apparent from the detailed description, figures and
claims set forth below.

strengthening elements of the bookcase 111 together with the
sidewalls 108, 110, and the top and bottom plates 104, 106.
[0044] In one embodiment, the shelves 112 are adjustable and form a
shelving system. The shelving system may help provide overall
support to the movable object 102. Different shelf arrangements or
configurations can provide different support to the bookcase 111.
Adjustable shelves provide flexibility so that the shelves 112 can
be arranged to a particular need. Vertical wall 116, in one
embodiment, separates the first accessible side 111 and the second
accessible side 121 of the movable object 102 for alternative
access.
[0045] The outside structure 200 provides structural support for
the movable object 102. The outside structure 200 includes a top
stationary plate 210, a bottom plate 202, and two vertical support
members 204 and 206. In this embodiment, the outside structure 200
is anchored to a wall 212 via two security brackets 214 and
216.
[0046] FIG. 1B depicts the movable object 102 moved from the
original space that it occupied. Portions of the link mechanism
400, which will be described more fully with regard to FIG. 1F can
be seen.
[0047] FIGS. 1C and 1D show the second accessible side 121 of
movable object 102, which in this embodiment isan entertainment
center. The second accessible side 121 of the movable object 102,
as shown in FIGS. 1C, 1D and 1E, includes shelves 118, articles 120

[0049] As seen in FIG. 1C, in one embodiment, the shelves include
moldings 140 prevent stored articles from sliding off of the shelf
during rough, sudden, or fast rotation.
[0050] The outside structure 200 of this embodiment, best depicted
in FIG. 1F, provides support for the movable object 102 and also
supports the rotaxial link mechanisms 300 and 400. In this
embodiment, outside structure 200 includes a stationary base 202, a
top stationary plate 210 (shown in FIG. 1A) and vertical support
members 204, 206 located respectively on the left and right sides
of the outside structure 200. Base 202 preferably rests on floor.
Vertical support members 204 and 206 at their lower ends are
attached firmly to base 202 and their upper ends are firmly
connected to top stationary plate 210. All four components (202,
204, 206 and 210) form the strong outside structure 200. A strong
outside structure 200 is desirable when heavy loads are introduced.
For additional vertical stability, the top plate 210 is anchored to
a wall 212 of the environment where the reversible storage
structure 100 is located by security brackets 214 and 216. In
another embodiment, vertical support members 204 and 206 may be
directly anchored to a concrete floor for heavy loading
applications. In yet another embodiment, vertical support members
204 and 206 may be anchored to a ceiling or roof. In certain
applications it may be desirable to eliminate both the base 202 and
the top plate 210 and attach the vertical supports directly to the
floor or ceiling of the environment in which the reversible storage
structure is located.
[0051] Referring back to FIG. 1F, the reversible storage structure
100 further includes a bottom rotaxial linkage mechanism 300 and a
top rotaxial linkage mechanism 400. Depending on the application,
and the loading, of the movable object 102, top rotaxial linkage
400 may not be necessary.
[0052] The rotaxial linkage mechanism includes multiple links
capable of rotaxially, that is a combination of a rotating movement
and a transverse movement. Preferably the rotaxial linkage
mechanism is constructed to allow an object to be moved from an
original space in a first orientation and returned to the original
space in a different orientation. Preferably the rotaxial linkage
mechanism includes a first link 304 and a second link 308. The
outer ends of first and second links 304 and 308 of rotaxial
linkage mechanism 300 may be rotatably connected to the base 202.
Preferably base 202 has risers on each side to which the first and
second links are preferably rotatably connected by first and second
pins 310 and 312. The inner ends of first and second links 304 and
308 are preferably rotatably connected to plate 306 by third and
fourth pins 314 and 316. A plate 306, in this embodiment, is
preferably bolted to the bottom plate 104 of the movable object
102. First and second links 304 and 308 and plate 306 are connected
serially and form a three movable link chain. This three-link chain
together with the stationary base 202 form the preferred rotaxial
linkage mechanism 300. The inner ends of the first and second links
are preferably also rotatably attached to a low friction contact
device such as for example, wheels, rollers, gliders or casters
that are attached between the links and the base. The low friction
contact device may also simply include the use of low friction
materials for the base and the links or a low friction piece of
material attached to the inner end of the links. The risers may be
used to elevate the first and second links to compensate for the
space needed for the low friction contact device. The preferred
embodiment employs wheels 350 and 352 as the low friction contact
device.
[0053] Depending on the application, plate 306 can be eliminated
and first and second links 304 and 308 may be connected directly to
bottom plate 104. In the embodiment where the first and second
links 304 and 308 are connected directly to bottom plate 104, the
first and second links, the bottom plate 104 and the base 202 form
the rotaxial linkage mechanism. In yet another application the
outer ends of the links can be rotatably attached to the floor to
form the rotaxial linkage mechanism. In the latter embodiment
appropriate spacers between the floor and the links should be
employed to compensate for the distance needed by low friction
contact device.
[0054] Top rotaxial linkage mechanism 400 is preferably located
between the outside structure 200 and movable object 102. The top
rotaxial linkage mechanism 400 is constructed, in one embodiment,
substantially similar bottom rotaxial linkage mechanism 300. Top
rotaxial linkage mechanism 400 provides top support for the movable
object 102 The outer ends of top first and top second links 404 and
408 may be rotatably connected to top plate 210. Preferably the
links 404 and 408 are rotatably connected to vertical support
members 204 and 206 by pins 410 and 412. The inner ends of links
404 and 406 are preferably connected to a plate 406 by pins 414 and
416. Plate 406, in one embodiment, is bolted to top storage plate
106. As described with regard to the bottom rotaxial linkage
mechanism, links 404 and 408 and plate 406 are connected serially
and form a three link chain. As with the bottom rotaxial linkage
mechanism 300 there are various embodiments that will provide the
desired rotaxial movement. Top and bottom rotaxial linkage
mechanisms 300 and 400 together with outside structure 200 form
means to hold and support the movable object 102 and provide a
predetermined path for its transitional movement from one alternate
orientation to another.
[0055] Top rotaxial linkage mechanism 400, in one embodiment, is
constructed similar to the bottom rotaxial linkage mechanism 300.
As such, the length of the links of top rotaxial linkage mechanism
400 is substantially same as the links in bottom rotaxial linkage
mechanism 300. Because of this, the respective pins of both bottom
and top rotaxial linkage mechanisms 300 and 400 are located on the
same axes allowing relatively jam free rotation of the movable
object 102.
[0056] In the presently preferred embodiment, bottom and top
rotaxial linkage mechanisms 300 and 400 are connected to each other
to form a synchronized rotaxial linkage mechanism. This facillitaes
the movement of the movable abject helping to form a strong and
rigid reversible storage structure that can hold significant load.
The synchronized rotaxial linkage mechanism preferaby comprises two
rotaxial linkage mechanism interconnected in a manner that such
that the first bottom link and the first top link rotate around
their respective outer ends simultaneously and strike the same
length arc. Similarly, the second bottom link and the second top
link rotate around their respective outer ends simultaneously and
strike the same length arc. In the preferred embodment, a torsion
bar 430 is used to interconnect the two rotaxial linkage
mechanisms. Preferably the outer end of torsion bar 430 is
connected to the first bottom link 304 at its pin 310 and the other
end of the torison bar 430 is connected to first top link 404 at
its pin 410 to form a rigid coupling between first bottom link 304
and first top link 404. Partially due to the rigid coupling, links
304 and 404 are able to rotate synchronously and reduce the
possibility of jamming. Minimizing the possibility of jamming is an
advantage of the present invention over the conventional rotating
cabinetry design, such as described in U.S. Pat. No. 4,124,262.
Another advantage of employing vertical bar 430 is to enhance the
safety of the reversible storage system 100 since it reduces the
possibility of being tip-over.
[0057] To provide additional strength, a fully synchronized
rotaxial mechanism may be employed. The fully synchronized rotaxial
mechanism comprises a synchronized rotaxial mechanism with a rigid
connection between the second top and second bottom links. The
rigid connection, is preferably accomplished by adding a second
torsion bar 440 and connecting one end of torsion bar 440 to seond
bottom link 308 at pin 312 while the other end of torsion bar 440
is connected to second top link link 408 at pin 412 to form a rigid
connection between links 408 and 308. This second torsion bar 440
increases the strength of the reversible storage system 100 and
with the first torsion bar 430 further decreases the likelihood of
jamming during movement.
[0058] FIGS. 1G and 1H illustrate preferred features of wheels 350
and 352 in accordance with one embodiment of the present invention.
Referring to FIGS. 1G and 1H, wheels 350 and 352 are attached to
the bottom rotaxial linkage mechanism 300. They are attached to the
inner ends of bottom first and bottom second links 304 and 308 of
the rotaxial linkage mechanism. The wheels support the load from
the movable object 102 when it rotates and also when it is in
stationary position. Weight of the movable object 102 is
transferred by the wheels to base 202. The wheels roll across the
base 202 in an arc as constrained by the rotation of the bottom
links. The wheels 350 and 352 in this embodiment are non-rotatably
attached to the links 304 and 308. It should be noted that the
wheels may also be rotatably attached. The non-rotatable attachment
feature simplifies the design. Base 202 preferably has smooth
surface along the arc struck by the rotation of the links to
provide for smooth rotaxial movement of the movable object 102.
[0059] FIG. 11 illustrates an embodiment that includes an
electrical, phone or other data type outlet or connection in the
movable object 102. This is preferably accomplished by attaching
cables 250 which may carry electricity, phone signals, cable TV
signals or other date signals, to top second link 408. For example
cable 250 is shown used for transporting electrical power and
signals running from outside of the reversible storage system 100
along link 408 to the articles such as TV 120, stereo system 122,
lamp 138, and et cetera. In one preferred embodiment, the cable 250
includes a loop 252 at each point of attachment that is
sufficiently large to compensate for the movement of the second top
link 408. While other types of cable connections exist for making
theset types of connections and may certainly be employed, this
loop type connection which may be used because the present
invention allows an object to be alternatively reoriented without
exceeding a 360 degree movement, may improve service life of the
cables. In another embodiment, cables 250 run inside of link 408 or
inside a torsion bar 440 that is hollow.
[0060] FIGS. 1J and 1K illustrate a reversible storage system 100
with a locking device 136 in accordance with the present invention.
Locking device 136 attached to frame wall 116. It has locking bolt
144 and spring loaded wedged bar 146. When locks are engaged they
go inside the holes in the vertical member 206 of the outside
structure 200. A purpose of having a locking device 136 is to
secure stationary position of the frame from unintentional
movements. The locking device 136, in one embodiment, is operable
with a key to protect cabinet from unauthorized rotation and from
unauthorized access to the other side of the cabinet. The rotating
object 102, in one embodiment, has handles 240 on the side of the
object facilitating the rotation.
[0061] FIG. 1L shows a reversible storage system 100 having a
control system 1019 in accordance with the present invention.
Control system controls the rotation of the movable cabinet through
electrical systems and mechanical devices including a motor. Gear
motor 260 is mounted at the top of the vertical member 206 with
hinge 262. Square telescopically built shaft 264, 266 transfers
rotation to a worm 268 and then to a worm gear 270. Worm 268 and
worm gear 270 with ball bearings 274 and 276 located in the gear
housing not shown in FIG. 1L. Output shaft of the worm gear
attached to the top plate 106 of the storage. Rotation of the motor
is transferred by described mechanism to the rotation of the
storage. Change of the storage position relative to the outside
structure is compensated by telescopic shaft 264, 266 and also by
hinge 262.
[0062] FIGS. 1M and 1N illustrate a structure having an additional
compartment 170 in accordance with the present invention. In this
embodiment, there is one more vertical wall 116 is installed inside
of the rotating object 102. This second wall 116 is installed with
small distance from the first one. On the right side of the storage
wall as shown in FIG. 1M there is opening on the sidewall 110. So
there is additional "secret" compartment 170 in the storage that
can be useful for many applications such as storing maps and
drawings. FIG. 1N shows a fully displayed map 180 pulled out of the
compartment 170.
[0063] In operation, movable object 102 shown in FIG. 1A is
positioned with one side of the movable object 102 open for access.
This side is holding books. Most of the time cabinet is in one of
the stationary positions or orientations with one of two main sides
open for access. In one embodiment, some modifications of the built
storage protective covers 130, 132 should be unlocked for access to
"open" side. FIG. 1A also illustrates another side of the movable
object 102 faces the wall 210 and therefore is not accessible.
[0064] To access the other side of the movable object 102,
operation starts from release the locking device 136 if it is
engaged. Then one pulls the cabinet frame away from the wall 210
using one of the handles 240. Because the pins 314 and 316 are part
of the outside structure 200, the motion can be deduced from
knowing the directions of the movement of these pins. The direction
of the motion of the pins 314 and 316 is perpendicular to their
links themselves. In starting position, links 304 and 308 are
parallel, therefore motion of the movable object 102 at starting
point is rectilinear without rotation. Moveable object 102 is
directed away from the wall 212 with small angle to the one of the
left or right sides. Transitional positions of the storage rotation
are shown on FIGS. 1B-1D. FIG. 1E shows second standard position
for access of the articles that are held on opposite side to the
first access side. This second side is shown with articles related
to TV and stereo system. One can engage locks 136 if needed.
[0065] FIG. 2 illustrates a storage structure 100 with different
storage articles in accordance with one embodiment of the present
invention. FIG. 2 shows the application of the storage structure
100 for holding or safekeeping collectibles 152 and 154, such as
knives and coins. Holder 160 holds knives and coins in place. The
second side of storage structure 100 may be used for storing books.
Above one of the cabinet shelves lamps 138 may be located to
provide light when it is needed. For keeping articles from sliding
off the movable object 102, holders, such as 160 can be added for
stronger attachment of the articles to one of the accessible sides.
In addition to the depicted holder, cells, clamps, brackets, hooks,
locks, etc., can be used.
[0066] FIG. 3 illustrates a structure with different storage
articles in accordance with one embodiment of the present
invention. FIG. 3 shows the safekeeping of the firearms 156 and
158, wherein the firearms 156 and 158 are held to the movable
object by holders 142.
[0067] FIG. 4A-4D illustrate a structure 1300 having light articles
storages 1106 and 1116 mounted on a desk 1202 in accordance with
one embodiment of the present invention. FIG. 4A shows two designs
of light article storages 1106 and 1116 that are shown in two
alternate positions. There are two minor differences in their
common components. In one embodiment, the length of the fourth,
stationary link defined by distance from joint 1310 to joint 1312
is shorter than the size of the bottom plate 1104. This
particularity that length of the stationary links 1310 and 1312 is
larger than the bottom plate 1104 allows implementation of simple
straight torsion bars outside of the storage frame to connect lower
and upper outside links (1304 with 1404 and 1308 with 1408).
[0068] Second difference between common components of invention
implementations shown in FIG. 4A and FIGS. 1A-E is as follows. In
FIG. 4A-4D, one access side is shown with shelves, second opposite
access side is shown blank without shelves. It can be used for
simplified storage to post notes, calendars, list of things to do,
or just to use it as a black board or screen, etc. If desired,
second access side also can have more developed storage
accommodations. They can be different depending on articles to be
stored.
[0069] All common parts in FIGS. 1 and 4 are designated with the
same numbers. FIG. 4A shows a right storage 1106 in first starting
position with side labeled "open" available for access. A left
storage 1116 is shown in rotated 180.degree. in opposite and
alternate position as the right storage 1106. Side labeled "open"
is facing back wall 1212 and this side is closed for access. Both
storages 1102 are mounted on the simplified outside structure that
in this embodiment is the top plate 1202 of the desk or table. Back
wall 1212 is optional.
[0070] FIG. 4B shows exploded view of FIG. 4A with visible parts of
bottom rotaxial linkage mechanism 1300. Mechanisms of both storages
are identical but shown in alternate positions corresponding to the
storages being in opposite positions.
[0071] FIG. 4C shows exploded view of the structure 1320 when
storages are in reversed position relative to FIGS. 4A and 4B. FIG.
4D shows cross-section of the bottom rotaxial linkage mechanism
1300 through the link 1308. This cross-section shows standard
design of the all links and their hinged connection to the
stationary base 1202 and to the movable link 1104 where it is at
the same time the bottom plate of the storage 1102. Joints 1312 and
1316 in this embodiment are constructed substantially the same. For
simplicity of the example, joints 1312 and 1316 are shown without
special rotation bearings. Joints 1312 and 1318 are made from
metal. Link 1308 is made from plastic with good tribological
performance to provide good friction pair to the joints. Being made
from plastic link 1308 will have also good friction performance
when it is sliding on the surfaces of the stationary plate 1202 or
bottom plate 1104. In another optional configuration joints and
links can be made from metal with bearings installed between them.
To improve sliding between the links and the plates 1202 and 1104,
links can be covered on their sliding surfaces with fabric or felt
with good friction properties.
[0072] FIGS. 5A-5E, 6A-6E, 7A-7E, 8A-8E show examples of different
geometrical variations of link system for performing rotaxial
movement in accordance with the present invention. Also these
figures demonstrate the principle of how these implementations
work. To simplify the demonstration of working principle of present
invention, only bottom plate 104 of rotating storage is shown. All
movements of the bottom plate 104 as shown in FIG. 1A, will
represent the movements of the proposed reversible storage relative
to the stationary base 202.
[0073] FIG. 5A illustrates a bottom plate 104 of the reversible
storage system 100 at points B and C connected respectively by
revolute joints 314 and 316 to links 304 and 308. Outside ends of
the links 304 and 308 connected by revolute joins 310 and 312 to
stationary base 202. In the theory of mechanisms stationary plate
202 can be viewed as stationary link AD. Three links AB, BC and CD
represent movable serially connected part of the mechanism where
bottom plate 104 of the reversible storage can be viewed as middle
link BC also designated as 306. Movable three-link chain AB, BC and
CD together with stationary link AD represents four-link mechanism
that determines the positions and the process of movement of bottom
plate 104 and therefore determines the positions and the process of
movement of reversible storage cabinet whereby is being means of
holding storage cabinet relative to stationary base 202.
[0074] FIG. 5A-5E are diagrams illustrating a compound movement
link mechanism for the storage structure in accordance with one
embodiment of the present invention. Referring to FIG. 5A-5E,
figures show the essence of inner workings of implementation shown
on FIG. 4A-4D. These figures can represent also invention
embodiment illustrated in FIGS. 1A-1E with shortened stationary
link AD. For more exact representation illustrated in FIGS. 1A-1E,
joints A and D should be outside of the bottom plate 104 (or plate
104 should be shorter than link AD).
[0075] In one implementation, revolute joints A and D are located
at remote sides of the stationary base generally in the middle area
of short, left and right sides of the storage frame. Points B and C
for revolute joints 314 and 316 are located on different sides of
the line AD generally symmetrically relative to this line. Also
joints B and C located at the middle of the front and backsides of
the bottom plate 104. In order for bottom plate 104 to rotate
between alternate positions spaced generally 180.degree. apart BC
is generally perpendicular to AD in starting position of the
storage, i.e. FIG. 5A.
[0076] The process of reversing the position of the plate 104 (i.e.
movable storage) from the starting position of FIG. 5A to
180.degree. reversed final position in increments of 45.degree. is
shown on FIGS. 5B-5E. Rotation of the plate 104 starts by pulling
right side of the movable object represented here by plate 104 in
direction from back to front. In all transitional positions as seen
on FIGS. 5B-5D storage as represented here by bottom plate 104 is
not crossing backside of the stationary plate 202. Available
clearance shown as dimension "a" serves as needed margin for this
requirement. In this embodiment for not obstructed rotation of the
storage there should be some clearance on left and right sides of
the movable object 102.
[0077] FIG. 6A-6E are schematic representations 100 illustrating an
operations of the storage with outside joints of the four link
mechanism moved back on the stationary plate in accordance with one
embodiment of the present invention. FIG. 6A shows, in one
embodiment, the locations of points A and D representing revolute
joints 310 and 312, which are moved back on stationary base 202.
Locations of revolute joins B and C are shifted left (as shown in
FIG. 6A) on bottom plate 104. Line BC remains perpendicular to AD
on starting position.
[0078] FIGS. 6B-6D show transitional rotation of plate 104 in steps
of 45.degree. to a position shown in FIG. 6E in which plate 104 is
in 180.degree. reversed position relative to starting position of
FIG. 6A. Previously back side of bottom plate 104 shown in FIG. 6A
that did not have access to it occupies now front position in FIG.
6E and became accessible now. This embodiment shows that in
transitional positions especially close to position as shown in
FIG. 6C points B and C are not moved so much forward as shown in
FIG. 5C. This means that stationary plate 202 that supports wheels
350 and 352 (see FIG. 1F) located generally under the revolute
joints B and C does not need to extend much forward, it can be
smaller. Also this variation of present invention saves space in
front of the storage for transitional positions of the storage and
can be more stable against tip-over.
[0079] For clarity of the explanation of the principal differences
between different modifications of the present invention the
changes are shown on the drawings but secondary differences, mostly
dimensional are not reflected on the drawings. For example, FIG. 6A
shows joints A and D, B and C that are located at positions that
allow some uniformity with the other drawings but for optimization
of each particular embodiment locations of these joints could be
changed. For example, joints A, D shown in FIG. 6A could be moved
more apart from each other to allow even better clearance than
shown on FIG. 6C.
[0080] FIG. 7A-7E are schematic representations 700 illustrating
operations of the storage with outside joints of the four link
mechanism located in diagonal corners of the stationary plate in
accordance with one embodiment of the present invention. In this
embodiment, joints A and D as shown in FIG. 7A are located at
diagonal corners of stationary plate 7202. Joints B and C are
located on the bottom plate 7104 approximately in the middle areas
of its front and back sides at positions on different sides of the
line AD and line BC in starting position as shown in FIG. 7A is
perpendicular to line AD.
[0081] FIGS. 7B-7D show transitional rotation of plate 7104 in
steps of 45.degree. to position shown in FIG. 7E where plate 7104
is in 180.degree. reversed position relative to starting position
of FIG. 7A. Previously back side of bottom plate 7104 shown in FIG.
7A that did not have access to it occupies now front position in
FIG. 7E and became accessible now. One of the most important
advantages of this embodiment is that during rotation for
180.degree. in all transitional positions the movable storage
generally does not need clearance or additional space for rotation.
This is because during rotation of the storage its transitional
positions are shifted away from the generally short side,
particularly the side where one of the joints A and D is moved
forward. The left side as shown in FIG. 7A does not need extra
clearance. One of the applications when this advantage can be
realized is when two storage cabinets are located side by side next
to each other as shown in FIGS. 9A-9C.
[0082] FIG. 8A-8A schematic representations 800 illustrating
operations of the storage with outside joints of the four link
mechanism located in diagonal corners of the stationary plate and
storage rotating 90.degree. between positions of alternate access
in accordance with one embodiment of the present invention. FIG. 8A
shows another modification of present invention. It can be viewed
in comparison with previous example as having stationary base 8202
and bottom plate 8104 generally as square plates.
[0083] As shown on FIG. 8A, for clarity but not necessary in real
embodiment, stationary plate 8202 is larger than bottom plate 8104.
Joints A and D are located at remote diagonal locations of the
stationary plate 8202. B and C joints are located at positions of
bottom plate 8104 generally symmetrically to the center point O of
the line AD in a such way that line BC forms 45.degree. angle with
the line AD. Plate 8104 has optional rounded corners 170. On back
and right sides of the storage are shown obstacles 8220 and 8222.
They can be walls, barriers, other similar cabinets, etc. For easer
understanding of the process of rotating the storage from starting
access position as shown in FIG. 8A to reversed, final access
position as shown in FIG. 8E bottom plate 104 has labels marking
all four sides as viewed from starting position.
[0084] Because of 45.degree. degree angle between BC and AD angular
distance between two alternate access positions is 90.degree. (not
180.degree. as in previous examples). Transitional positions from
starting to final position are shown in intervals of 22.5.degree.
shown in FIGS. 8B-8D. During rotation of the bottom plate 8104 this
plate will not interfere with back and sidewalls of 8220 and 8222
especially if it has rounded corners 8170 or if there is even minor
clearance between bottom plate 104 and walls 220 and 222. Because
of the rotation of the plate 104 for alternating access to the
sides of the storage is 90.degree. (not 180.degree. as in previous
examples) alternating access to the sides of the storage is planned
differently. For example, a storage structure may be organized into
front and backsides (as shown in FIG. 8A) for holding articles.
Left and right sides are blank. Only front side as shown in FIG. 8A
has access to its articles and backside is blocked from accessing
to articles by wall 8220. After storage rotation by 90.degree.
clockwise to position as shown in FIG. 8E "front" labeled side has
no access because it is blocked by wall 8222. "Back" labeled side
is open for access from the right side.
[0085] Second example of storage structure is that only front side
has developed storage structure for holding essential articles
while other three sides could be just blank walls. Then rotation of
storage by 90.degree. will block access to storage completely.
Rotation of the storage back to starting position will open front
side again for access. There could be more other applications of
present inventions that could differ in details but follow the
essentials of proposed inventions. To rotate bottom plate 8104 as
representing storage rotation backward from final alternate access
position to starting alternate access position for all four
previous examples one has to follow shown figures from "E" to
"A".
[0086] FIG. 9A-9B are diagrams 900-920 illustrating a storage
designed for light loads mounted on a desk with rotaxial designed
illustrated in FIG. 8A-8E. FIG. 9A represents practical
implementation of proposed invention per modification shown on FIG.
7A-7E. FIG. 9A shows two storages 9002 and 9004 as shown. For
clarity the sides for storage access are labeled "open". In this
example, they are on the front sides of starting position. Details
of operation and construction are similar to steps shown in FIG.
4A-4D.
[0087] FIG. 9B shows exploded view of FIG. 9A. FIG. 9C shows
exploded view of the storage when it is rotated 90.degree.
counterclockwise for left storage and clockwise for right storage.
In these alternated positions, open sides of the storage are
blocked by neighboring storage. In this example, two storages are
located next to each other and do not interfere with each other
during rotation utilizing the advantages of the scheme represented
in FIGS. 7A-7E.
[0088] FIG. 10A-10C are diagrams 2100 illustrating a storage
rotating between alternative accessing positions around horizontal
axes in accordance with one embodiment of present invention. FIGS.
10A, 10B and 10C show simplified and modified version of structure
shown in FIG. 1A in which FIG. 10A shows nominal starting position
of the storage while FIG. 10B shows an 180.degree. reversed of the
storage with alternative accessing position of the storage. FIG.
10C shows explored view of the storage in starting position.
Simplification is achieved by omitting optional features of the
design shown in FIG. 1A-1L including omitted torsion bars, wheels,
lamps, cables, glass covers, locks, trimmings, etc. A modification
of this embodiment is means for holding the storage frame whereby
giving the storage its kinematical determination are located not at
the bottom and top sides of the frame but on the left and right
sides of the storage frame. It looks like vertical storage as shown
in FIG. 1A was turned back 90.degree. from vertical to horizontal
position. In this position previously front side shown in FIG. 1A
became upper side of storage shown in FIG. 10A. Previously bottom
side became right side and previously right side became front side
as shown in FIG. 10B.
[0089] All common parts shown in FIG. 10A and FIG. 1A are shown
with the similar number designations. The storage 2100 includes
movable object 2102 that is to hold articles, also the storage
includes means to hold proper storage 2102 in which box 2200
represents optionally developed outside structure and rotaxial
linkage mechanisms 300 (right one) and 400 (left one). Movable
object 2102 is build in this example as flat horizontal box open
from top and bottom includes right plate 2104, left plate 2106, and
optional front and back walls 2108 and 2110. The frame also
includes cellular holder 2160 to hold articles that are not shown
here for generalization purposes. Top holder is arbitrary shown in
this example as having 48 cells for articles and bottom holder 2162
shown in FIG. 10B has 24 cells.
[0090] Holding means include box 2200. Box 2200 has optional cover
2250. Right and left walls 2202 and 2210 of the box 2200 serve as
stationary bases of the right and left side rotaxial linkage
mechanisms 2300 and 2400 respectively for holding of proper storage
2102. There are also front and back walls 2204 and 2206,
respectively.
[0091] Right rotaxial linkage mechanism 2300 and left rotaxial
linkage mechanism 2400 connect storage 2102 with outside box 2200.
FIG. 10C shows details of the right rotaxial linkage mechanism
2300. Left rotaxial linkage mechanism 2400 is not visible on this
view but it is generally the same as rotaxial linkage mechanism
2300 as being symmetrical to it on the other side of the storage.
Links 304, 306 and 308 of rotaxial linkage mechanism 2300 connected
serially represent the movable part of the rotaxial linkage
mechanism 2300 and by their outside ends connected to the
stationary box wall 2202 by pins 2310 and 2312. Links 2304 and 2308
by their inner ends connected to the right plate 2104 of the
storage 2102 by pins 2314 and 2316.
[0092] Movable three-link chain 2304, 2306 and 2308 together with
stationary link 2202 represents four-link mechanism, which
determines the positions and the process of movement of bottom
plate 2104 and therefore determines the positions and the process
of movement of reversible storage 2102 whereby is being means of
holding storage cabinet relative to the stationary base 2202. The
same is true for left rotaxial linkage mechanism 2400. Because of
the substantial symmetry of the right and left rotaxial linkage
mechanisms 2300 and 2400 and the relative uniformity of the
gravitational load this embodiment even without torsion bars is
providing generally jam free reversing of the storage 1102 for
alternative accesses to upper and bottom sides of storage 1102. If
there is more demanding application for strength, reliability and
smoothness of the operation of the storage then storage can be
modified, e.g. by introducing torsion rods.
[0093] FIG. 11A-11D are diagrams 2400 illustrating application of
proposed invention with for four square storages mounted next to
each other on one square stationary plate in accordance with one
embodiment of present invention. FIGS. 11A-11D show an embodiment
of four substantially identical storages located next to each other
in circular symmetry around central axis. There is no obstruction
around this group of storages. This group of storages can be
accessed from all four sides. Stationary plates of all four
storages combined into one common stationary plate 3202 serving all
four proper storages 3102. Each proper storage 3102 has one side
with developed shelving 3112. For clarity on the top of each
storage label "open" is placed on the side with shelving for each
storage 3102.
[0094] Detailed mechanical operation of this embodiment is similar
to the operation shown in FIGS. 8A-8E. FIG. 11B shows all four
proper storages rotated 90.degree. clockwise to the second
alternated positions. All four "open" sides with open shelves are
closed for access.
[0095] FIG. 11C shows a top view of the structure shown in FIG. 11B
including rotaxial linkage mechanism 300 links conditionally shown
as visible through the storage parts. Designations of the
components are similar to designations shown in FIG. 8A. There is a
convenience if rotation of all four storages is synchronized so
that making one storage box to rotate makes all four storages to
rotate. In addition to rotating all storage boxes at once, when all
storage boxes rotate simultaneously, there is more margin for
clearance between them because each box is moving away from the
common center and gives more clearance for itself and two of its
neighboring boxes.
[0096] There could be many different schemes applied for
simultaneous rotation of these four boxes. FIG. 11D shows top view
of one of the simpler designs in accordance with the present
invention. Generally square shape member 3330 rotates around
central axis "O". This member has at each of its corners four
identical joints 3332. Each of these joints 3332 connected by link
3334 to links 3304 at joints B. Because of circular symmetry of the
system, rotation of all storages 3102 is synchronized.
Theoretically, there is dead point for rotation when link 3306 and
link 3308 are on one line, but as with other similar mechanisms
continuation of the storage rotation by inertia resolves these
situation for all practical purposes.
[0097] This note relates to all other features not only to handles.
Another important note relates to the meanings and usages of
terminology. In the theory and technology different people prefer
to use different words for description of same or similar things.
This description is using these words interchangeably, not taking
particular stand on this issue. Similar situation is with using
words as storage, cabinet, storage cabinet, bookcase, hatch,
etc.
[0098] Another example of interchangeability of words relates to
the words rotate, reverse, transpose, etc. Description is using the
word rotate in wide application of it--rotation not necessary about
static axis but rotation about axis that can be different at
different moments (like rotation about momentary axes). Reverse and
transpose relates mostly to results of motion than to process of
motion.
[0099] Although the description above contains much specificity,
these should not be construed as limiting the scope of the
invention but as merely providing illustrations of some of the
presently preferred embodiments of this invention. Thus the scope
of this invention should be determined by the appended claims and
their legal equivalents. Therefore, it will be appreciated that the

[0100] FIG. 12A-12D are diagrams illustrating a wheel system
attached to a link in accordance with one embodiment of present
invention. FIG. 12A shows a top view of wheel system 4200 having
two wheels 4202-4204 and a wheel frame 4210. The wheels 4202-4204
are mounted in a middle bar 4212 of the wheel frame 4210. The
wheels 4202 contact the ground or track while a portion of wheel
frame 4210 attaches to the rotating object. During the operation,
the wheels 4202-4204 can move in a predefined trajectory while a
portion of wheel frame 4210 that attaches to the rotating object
can move in a different orientation so that a rotaxial movement can
be accomplished.
[0101] FIG. 12B shows a cross-section view of a wheel system 4250
in accordance of one embodiment of the present invention. Referring
to FIG. 12B, a portion of the wheel frame 4210 attaches to the
rotating object or moving cabinet 4232 while another portion of the
wheel frame 4210 attaches to a link 4230 for performing link
assisted rotaxial turning.
[0102] FIG. 13A-13C are diagrams illustrating a rotating frame
capable of attaching a set of wheels in accordance with one
embodiment of present invention. FIG. 13A illustrates a rotating
frame 4300 having top plate 4302 and bottom plate 4304. In one
embodiment, the bottom plate 4304 further includes two
wheel-mounting places 4306-4308. The wheel mounting places
4306-4308 are capable of mounting wheel frames 4210 with sets of
wheels 4202-4204. The wheels 4202-4204 are further attached to two
links for controlling the turning of the movable object.
[0103] FIG. 13B is a 3D picture illustrating a structure 4310
having a two-link system with wheels wherein the bottom plate 4304
of the rotating frame has turned in 90 degree (extending forward)
from a set position. Set position means one side of rotating object
is accessible while another side of rotating object is not
accessible because it is covered by the back wall. The structure
4310 includes a bottom plate 4304, two links 4312-4314, ground
plate 4320, and wheels 4210. In one embodiment, the bottom plate
4304 performs a rotaxial movement in response to the movement of
the links 4312-4314.
[0104] FIG. 13C is a 3D structure 4350 having a bottom plate 4304
of the rotating frame 4300 in accordance with one embodiment of the
present invention. The structure 4350 shows the bottom plate 4304
in a set position.
[0105] FIG. 14 is a set of diagrams illustrating a rotating object
4400 performing a rotaxial movement in accordance with one
embodiment of present invention. FIG. 14 is a top view of the
rotating object 4400 wherein the rotating object 4400 has a
rotating axis 4402. Also, the object 4400 has two sides 4404-4406.
The set of diagrams shows a sequence of rotaxial movement to
reverse the side between side 4404 and side 4406 of the object
4400. During the operation of rotaxial movement, the object 4404 is
transported from front side to back side by compound motion.
Compound motion, in one embodiment, means rotating the object
around its rotating axis while the rotating axis moves alone a
predefined trajectory. Upon the completion of the rotaxial movement
or rotaxial rotation, the object is back to the same space with a
different orientation.
[0106] In the foregoing specification the invention has been
described with reference to specific exemplary embodiments thereof
It will, however, be evident that various modifications and changes
may be made thereto without departing from the broader scope of the
invention. The specification and drawings are, accordingly, to be
regarded in an illustrative rather than restrictive sense.
