Slide system
Abstract
The present disclosure provides enhanced slide that facilitates
efficient and safe access to items stored on upper shelves.
Exemplary system according to the present disclosure includes one
or more storage shelves support arms which are vertically mounted
on one or more horizontal slides. The arms configurations, which
are spring biased or track(s) mechanism guided, allows the arms to
travel outward, and then when they are blocked by a stop or aliened
with a track, to travel downward. In the case where the arms are
pivotally mounted on the slides, the slide system produces
horizontal and then arcuate movement of the shelves effectively
bringing upper shelves to a lower position. When the arms
interacting with guide track(s) mechanism, the slide system
produces horizontal and then vertical movement of the shelves
effectively bringing upper shelves to a lower position A mini
dumper wheel controls the speed of the arms while moving from upper
position to a lower position.

CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of two co-pending
and commonly assigned provisional patent applications, as follows:
U.S. Provisional Patent Application Ser. No. 60-469,186, filed May
12, 2003 and entitled "Slide Pivot System" and Provisional Patent
Application Ser. No. 60-489,613 ad entitle "Non Linear Damping
Method", filed Jun. 26, 2003. The entire contents of the foregoing
provisional patent application are hereby incorporated by
reference. This application is also a continuation-in-part
application based upon U.S. parent application No. 20030189021,
filed Feb. 21, 2003 and entitled Shelving System, and U.S. patent
application filed Mar. 31, 2004 and entitled Revolving Slide.
BACKGROUND OF THE DISCLOSURE
[0002] 1. Technical Field
[0003] This invention generally relates to a slide system that may
travels outward and downward. Upper shelves, which are mounted on
the arms, can be moved outward and away from lower shelves and
downward to an access level position. The lower shelves may be
movable upward past the upper storage area, such that the lower
storage area and the upper storage area trade places to permit the
upper storage areas to be easily accessed.
[0004] 2. Background Art
[0005] Slides are widely used for displaying and storing items.
Sometimes slides are contained within cabinets, armoires, closets,
etc., and are constructed to facilitate access to items stored
thereon. In designing storage, designers must ensure efficient
access to stored items. The height to which a stack of shelves can
extend is typically limited by the reach of a person of average
size. Alternatively, in some cases upper shelves are positioned out
of the reach of users and various tools are provided to permit
access to the contents of upper shelves. For example, users may be
provided with tools that include footstools, stepladder, reach
poles, etc. The use of such tools, however, can be inefficient and,
in some cases, can contribute to dangerous conditions. For example,
people may be injured from falls off of stepladders and/or
footstools. Likewise, the use of reach poles can result in
inadvertent knocking and/or dislodging of the desired item or an
adjacent item from the shelf. In such circumstances, item(s) may be
broken or, worse yet, item(s) may fall from the upper shelf,
potentially striking and injuring the person using the reach pole
or another person in the vicinity thereof. In addition, such tools
are typically a nuisance to have about, can lead to injuries merely
by tripping a person, and are frequently misplaced or not readily
available for use.
[0006] In the past, efforts have been directed to providing
moveable shelves to address the problems associated with fixedly
positioned shelves. Examples of previous efforts directed to
developing enhanced shelving systems, which are disclosed in the
patent literature include the following U.S. patents.
[0007] Ochse, U.S. Pat. No. 1,940,877, discloses extension shelving
for display cabinets wherein the shelving may be drawn out of the
display cabinet by means of tracks and rollers, and the shelves may
be tilted to assume a rearward ascending step-wise arrangement, the
lower-most shelf extending forward of the cabinet and the upper
shelves.
[0008] Snyder, U.S. Pat. No. 3,640,389 discloses a display stand
and expandable shelf for use thereon. The Snyder '389 system
includes a base and a pair of upright shelf supports. The
components of the system are slidably engageable with each other
and conventional fastening means are not required for assembly.
Additionally, the shelves include a portion (80) that can be
extended vertically upward from the remainder of the shelf (70) to
form a step, and other portion(s) (90 and 96) can be extended
horizontally outward from the shelf to form a wider shelf (again
having a step).
[0009] Brauning, U.S. Pat. No. 4,056,196 discloses a supporting
framework for shelves including crosspieces interconnected with
uprights. The cross pieces can ride up and down the uprights and,
when positioned in a desired location, can be locked into place by
a locking mechanism.
[0010] Wyckoff, U.S. Pat. No. 4,651,652 discloses a vertically
adjustable work desk that is raised by a force applied by a
lockable gas spring via a first pulley system. A second pulley
system insures that all areas of the work surface are equally
raised.
[0011] Duff et al., U.S. Pat. No. 4,919,282 discloses movable
gondola shelving for merchandise display having a rolling base that
supports channeled uprights and a center panel. Cantilevered
shelves are interconnected with the channeled uprights by means of
cam assemblies at the rear corners of the shelves. The cam
assemblies allow for the shelves to be vertically adjusted while
the shelves are maintained in a level position.
[0012] Sugasawara, et al., U.S. Pat. No. 5,011,029 discloses a
so-called coat lift hanger for storing coats and/or other garments
in a storage area located at a relatively high position of a
wardrobe or wall in a room comprising a hanger pipe for removable
hanging and storing coats and/or other garments, an arm capable of
being pivotally tilted forward and be returned to its uprightly
standing position for moving up and down said hanger pipe fitted to
its upper end and a rotary lever located at a relatively low
position for tilting and returning said arm.
[0013] Bustos, U.S. Pat. No. 5,014,862, discloses an assembly for a
cantilevered display header for a gondola display rack that
includes two uprights braced to the gondola display rack in
vertical spaced relation. The header, which defines a light box
that can receive a sign for illumination thereof, is mounted
separately from the shelf and is vertically moveable with respect
thereto for adjusting the height of the header with respect to the
shelf.
[0014] Vogelgesang, U.S. Pat. No. 5,482,347 disclosed a pull down
shelf assembly for facilitating access to an upper storage shelf.
The storage shelf is movably mounted to a shelf guide track
mechanism for movement between an extended position and a retracted
position. The pull down assembly includes a pair of arms pivotally
mounted to the track mechanism and the mounting bracket member at
spaced-apart locations. This configuration produces pantographic
movement of the track mechanism throughout an arcuate path between
a deployed position and an elevated stored position while
maintaining the horizontal orientation of the shelf.
[0015] Duane, U.S. Pat. No. 5,950,846, discloses a storage rack
that includes vertically and horizontally moveable supports. The
storage rack includes plural spaced horizontal supports for
vertical motion. Vertical movement of the rack is powered by one or
more hydraulic cylinders carried in the vertical support columns,
and an associated control mechanism that allows adjustable vertical
positioning of the rack. Horizontal supports of a compound nature
are disclosed which permit lateral extension to expose material
carried on the support element.
[0016] Hardy, U.S. Pat. No. 5,970,887, discloses an extendable
shelf assembly that includes extender bars having slots and a
cooperating pair of rotatable sprockets that are affixed to an
axle. The sprockets include a plurality of teeth that engage the
slots of the extender bars.
[0017] Anderson et al., U.S. Pat. No. 6,065,821, discloses a
vertically adjustable shelf and support rail arrangement for use in
a cabinet. The shelf arrangement includes a pair of rotatably
mounted rear sprocket members and a driving mechanism for rotating
the sprockets to vertically adjust the shelf within the cabinet.
The driving mechanism can be manually or electrically powered, and
the adjustable shelf may include elements that ensure that the
sprockets are not disengaged from the rails while the shelf is
within the cabinet.
[0018] Terragni; Ezio, U.S. Pat. No. 6,105,795, discloses an
upwardly/downwardly movable clothes-hanger device which includes,
hanging rod for receiving the hung clothes and hanging rod support
members which are mounted on a supporting surface. The support
members capable of being pivotally tilted forward from a vertical
standing position to a horizontal position such as a user can
easily access to the hanging rod.
[0019] Rindoks et al., U.S. Pat. No. 6,112,913, discloses a support
arrangement for a furniture system that includes a support assembly
having a pair of standards which extend vertically in spaced
relate. Each of the standards includes two rows of openings
extending vertically in spaced relation. A first support member may
be detachably mounted in a pair of outermost rows of openings, and
a second support may be detachably mounted in a pair of inner most
rows of openings.
[0020] Santiago, U.S. Pat. No. 6,340,240, discloses a cantilever
shelf support system wherein the disclosed bracket includes a
plurality of forwardly projecting cantilevered male members for
insertion into mating female apertures formed in the shelf.
[0021] Adam, U.S. Pat. No. 6,164,610, discloses a pull down storage
shelf assembly wherein arms attached to an upper support member on
one end and a lower support member on the other end. When a handle
is pulled forward, the upper shelf rotates to the down position to
provide easy access to items on the upper shelf. A stop is placed
on the side of the upper support members to stop the downward
motion and support the shelf at the optimum working level.
[0022] In addition to the prior art efforts discussed above, the
present inventor has previously disclosed advantageous shelving
systems. In particular, U.S. Pat. No. 5,799,588 to Engel discloses
advantageous shelving systems wherein shelves are provided in a
stack arrangement mounted to two or more uprights. The uprights
include one or more shelf support members, which support the
shelves. One or more of the shelves are movable out from the shelf
stack, either by way of a telescoping support member, or otherwise,
to permit movement of such shelf or shelves to or past a lower
shelf. After an upper shelf or shelves are moved vertically past a
lower shelf, the upper shelf or shelves can be moved back into
alignment with the lower shelf. In this arrangement, the upper
shelf or shelves may be positioned below the lower shelf to permit
easy access to the upper shelf or shelves (and their contents).
Also, the present inventor has previously disclosed advantageous
shelving systems. In particular, U.S. patent application Ser. No.
20030189021 to Engel discloses advantageous shelving systems
wherein shelves are provided in a stack arrangement mounted to two
or more uprights. Upper shelf or shelves are repeatedly moved
vertically past a lower shelf and back into alignment with the
lower shelf such as that the shelves moved horizontally and
vertically in a revolving manner.
[0023] While these assemblies may be adequate to permit access to
upper storage assembly, most are deficient for one reason or
another. The Vogelgesang and the Hansen pivot down assemblies, for
instance, disclose a storage system which includes arms support for
supporting a plurality of kitchen cabinet shelves so that the
shelves may pivot outwardly and downwardly toward the user to an
access position. However; to allow the upper storage shelves to
pivot downward, a substantial lower storage shelves must be cleared
from items. Indeed to minimize the lost of shelving space, these
assemblies are limited to kitchen cabinets, which are typically ten
inches deep.
[0024] Other pivot-down assemblies require substantial floor space
to allow the shelves support to pivot downward. The Terragni and
Sugasawara patents for example, disclose a storage system which
includes arm(s) support for supporting a hanging rod so that the
cloths hanged on the rod may pivot about outwardly and downwardly
toward the user to an access position. However, in addition of lost
of storage space below the system, a substantial foot floor space
must be also cleared from objects to allow the upper hanging rod to
pivot downward.
[0025] In addition, many of the assemblies require an array of
springs biasing systems necessary to raise and lower the shelves.
This complex and bulky assembly is very costly and difficult to use
and assemble.
[0026] Accordingly, it is an object of the present invention to
provide a slide system which permits increased access to the upper
storage shelves.
[0027] It is yet another object of the present invention to provide
a slide system which allows upper shelves to travel downward to an
access position without the loss of lower storage space and loss of
foot floor print space.
[0028] It is yet another object of the present invention to provide
a slide system which allows upper shelves, when in down position,
to remain close to the lower shelves.
[0029] It is yet another object of the present invention to provide
a slide system, which allows upper shelves to travel forward
horizontally and away from lower shelves, and then pivot downwardly
toward the user to an access position.
[0030] It is yet another object of the present invention to provide
a slide system which allows upper shelves to travel forward
horizontally and away from lower shelves, and then slide downwardly
toward the user to an access position.
[0031] It is yet another object of the present invention to provide
a slide system which allows upper shelf(s) to trade place with
lower shelf(s).
[0032] It is another object of the present invention is to provide
a pull down storage shelf assembly which can be easily and safely
operated by children, the elderly and handicapped persons.
[0033] It is another object of the present invention is to provide
a pull down storage shelf assembly which includes a mini dumper
mechanism that permit reliable and efficient repositioning and
dampening of objects and loads.
[0034] It is an object of the present invention to provide an
economical dumper mechanism with a dumping distance longer than its
piston stroke length.
[0035] These and other objectives are satisfied by the revolving
slide and the enhanced shelving systems disclosed herein, as will
be apparent from the detailed description, which follows.
SUMMARY OF THE DISCLOSURE
[0036] The present invention describes two slide systems that allow
the movement of storage shelves from an upper position to a lower
position.
[0037] The first slide includes one or more shelves support arms
pivotally mounted on a horizontal slide(s). The slide allows the
shelves to move outwardly and a way from lower shelves. The arms,
however, allow the shelves to pivot downwardly from upper position
to a lower position, to permits easy access to the upper shelf or
shelves. Further, this slide assembly may include a guide track
mechanism to allow upper shelves do travel vertically downward
rather than travel downward in an arcuate path, and keep upper
shelves close to lower shelves when in down position.
[0038] The second slide includes one or more telescopic shelves
support arms mounted on horizontal slide(s). The slide allows the
shelves to move outwardly and a way from lower shelves. The
telescopic arms, however, allow the shelves to slide downward and
from upper position to a lower position to permits easy access to
the upper shelf or shelves.
[0039] To provide a damper mechanism having a compact size and
capable of absorbing an extremely high torque, an advantageous
dumping systems that permit a smooth repositioning of the slide or
shelves are disclosed in the present invention. The dumping system
includes a wheel and a damper. The wheel coacts with moving members
associate with the slide system or the shelves systems, e.g.
shelves support arms, through cable or rack. A linear or pivotal
motion of the moving members is translated to a rotational motion
of the wheel. The dumper, which attached to the wheel, controls the
speed of the wheel.

kitchen cabinetry and the like. In addition, the disclosed
"shelves" may take a variety of forms without departing from the
spirit and/or scope of the present disclosure. For example, the
exemplary "shelves" disclosed herein may alternatively take the
form of hanging rods, drawers, bins and the like. Additionally, the
disclosed slides systems may be manufactured and/or distributed as
free-standing, independent units or as components for use in
retrofitting existing shelving unit(s) and/or shelving system(s).
Thus, as used herein, the terms shelf, shelves, "shelving system"
and "shelving systems" are intended to broadly encompass
shelving/storage applications wherein storage is achieved through
vertically spaced storage elements and wherein efficiencies and/or
benefits may be achieved through vertical repositioning of such
storage elements.
[0083] While the present invention will be described with reference
to a few specific embodiments, the description is illustrative of
the invention and is not to be construed as limiting the invention.
Various modifications to the present invention can be made to the
preferred embodiments by those skilled in the art without departing
from the true spirit and scope of the invention, as defined by the
appended claims.
[0084] Finally, the present invention will be described with
reference to embodiments mostly comprise of a stack of shelves
mounted on one slide system in a cantilever manner. However, as
seen in some drawings thereafter, a pair of slide may be used to
support stack of shelves.
[0085] With reference to the enclosed figures, which depict
exemplary embodiments of slide systems according to the present
disclosure, reference is initially made to the exemplary Slide
System, generally designated 100, that is schematically depicted in
FIGS. 1-1.5.
[0086] Referring to FIGS. 1, a slide system is comprised of two
shelf support members (104,103) pivotally mounted by pins (114,
113) to a slide mechanism (120) which comprise of rail (101) and
roller (102). This configuration produces a linear and a arcuate
movement of the shelf support members between a retracted and
upward position (solid lines), and an extended and downward
position (dashed lines). The arms (103, 104) and pins location are
arranged in such way that the stack of shelves 105 maintains a
substantially horizontal orientation throughout this arcuate
movement.
[0087] In reference to FIG. 1.1, FIG. 1.1 provides a front view of
the slide system shown in FIG. 1 where the shelf support members
are in retracted and upward position.
[0088] FIG. 1.2 provides a front view of a shelf system comprises
of a stack of shelves (105) mounted on pair of slide system (150,
150'). The stack of shelves includes shelf 106 and shelf 107
attached together in a stack arrangement by front legs 110 and 110'
and back legs (not shown) 111 and 111'. The stack of shelves are
mounted on the left slide system (150) such as leg 110 mounted on
shelf support arm 103 by pin 123 and leg 111 mounted on shelf
support arm 104 by pin 124. In the same manner, the stack of
shelves mounted on the right slide system (150') such as leg 110'
mounted on shelf support arm 103' by pin 123' and leg 111' mounted
on shelf support arm 104' by pin 124'.
[0089] FIG. 1.3 provides a side view of a shelving system mounted
on the upper section of a cabinet side wall (112), in a way
apparent to persons skilled in the art, with the shelves 105 in the
upward position. A stack of shelves, generally designated 105', are
also attached to the lower section of the cabinet back wall
(122).
[0090] In operation, exemplary shelving system 100 operates to
facilitate repositioning of upper shelves 106, 107 relative to
second shelves 108, 109 by permitting outward horizontal motion of
upper shelves 106, 107 past or almost past lower shelves 108, 109
as shown in FIG. 1.4. When pulling shelf 107 outwardly a horizontal
motion of upper stack shelves 105 is accomplished by way of the
sliding functionality of the running member 102 associated with the
slide support member 101. Once stack of shelves 105 is outwardly
positioned, keeping pulling downward shelf 107, a downward arcuate
movement of shelves 105 is accomplished by way of the pivotal
functionality of the shelves arm support 103, 104 as seen in FIG.
1.5.
[0091] Not shown here, various springs biasing known in the art
keep arms in an upright position when the shelves 105 is in
elevated position and in horizontal position when shelves 105 is in
deployed position. When shelf 107 is pulled toward the user and to
an access position, the spring biasing means keep the arms 103 and
104 in an upright position while stack of shelves 105 travels from
a retracted position to an extended position. Once stack shelf 105
has been fully extended forward, stop 131 prevent the running
member 102 from further moving forward. At this point the springs
biasing element will contracted or extended and the stack of
shelves 105 will pivot downward toward the user and to an access
position.
[0092] With reference to FIGS. 2-2.4, exemplary Slide System 200 is
almost identical in structure and operation to exemplary Slide
System 100. As seen in FIG. 2, however, two additional components
were introduced with exemplary 200. The first component is a
guiding wheel 223, which is rotateably attached to shelf support
arm 103. The second component is a rail 220, which is comprised of
rail 221 and 222 and may mounted on rail 201.
[0093] Referring to FIGS. 2, a slide system is comprised of two
shelf support members (204, 203) pivotally mounted by pins (214,
213) to a roller (202). Roller 202 is positioned within rail 201
and travel therwithin. As shown in FIG. 2, a rail 220 or other
cooperative structure is formed by rail 221 and 222 and mounted to
the rail 201. Rail 220 cooperates with guide wheel or roller 223,
and the wheel is rotatably mounted to shelves arm support 203.
[0094] Turning to FIG. 2.1 a side view of a shelf system comprises
of a stack of shelves (205) mounted on a slide system is provided.
The stack of shelves includes shelf 206 and shelf 207 attached
together in a stack arrangement by front legs 210 and back legs
211. The stack of shelves are mounted on the slide system such as
leg 210 mounted on shelf support arm 203 by pin 223, and leg 211
mounted on shelf support arm 204 by pin 224. As shown in FIG. 2.1,
the shelving system mounted on the upper section of a cabinet side
wall (212), in a way apparent to persons skilled in the art, with
the shelves 205 in the upward position. As seen in FIG. 2.1, a
stack of shelves, generally designated 205' are also attached to
the lower section of the cabinet back wall (222).
[0095] Unlike exemplary 100, where the upper shelves are first
travel horizontally outward and then arcuately ally downward, as
seen in FIG. 2.1 through FIG. 2.4, the configuration of exemplary
200 produces a horizontally outward and then vertically downward
movement of shelves 205 (FIG. 2.1), and an extended and downward
position (FIG. 2.4).
[0096] In operation, exemplary shelving system 200 operates to
facilitate repositioning of upper shelves 206, 207 relative to
second shelves 208, 209 by permitting outward horizontal motion of
upper shelves 206, 207 past lower shelves 208, 209. As shown in
FIG. 2.1, a pair of arms 210, 211 maintains a substantially
horizontal orientation of stack of shelves 205. In addition, a
wheel or roller 223, which is rotatably mounted to shelf support
arm 210 and is adapted to ride on a rail 220, maintains the stack
of shelves 205 at an upper position. As shown in FIG. 2.2., when
pulling shelf 207 outwardly a horizontal motion of upper stack
shelves 205 is accomplished by way of the sliding functionality of
the running member 202 associated with the rail 201, and by way of
guide wheel 223 which runs inside rail 221. After an upper shelf or
shelves are moved vertically past a lower shelf, and when guide
wheel 223 aligns with vertical rail 222, the upper stack of shelf
205 can be moved vertically downward in alignment with the lower
shelf to permit easy access to the upper shelf or shelves. As seen
in FIG. 2.3-2.4, a vertical rather than an arcuate movement of
shelves 205 is accomplished by way of the engagement of wheel 223
with rail 222. Stated differently, by coacting with rail 222,
downward movement of wheel 223 cause shelves arms (210, 211) to
travel backward, thereby permitting the stack of shelves 205 to
move vertically and close to lower shelves.
[0097] Referring now to FIGS. 3-3.3, a third exemplary shelving
system 300 according to the present disclosure is schematically
depicted.
[0098] As seen in FIG. 3, slide system 300 includes upright support
mounted on horizontal support 301. A horizontal support 301
includes "box-like" beams 303, advantageously detachably mounted to
surrounding structure(s), e.g., walls, cabinetry, adjacent shelving
supports, etc. Beam 303 is sized and dimensioned to accommodate
horizontal movement of members 305 by ways of a ball bearings
member, and members 305 is sized and dimensioned to accommodate
horizontal movement of members 307 by ways of ball bearings member.
The horizontal telescopic functionality of support 301 allows
upright support 302, which mounted on moving member 307, to travel
along beam 301. The telescopic functionality may be achieved by
balls, rollers, wheels, and other ways as will be readily apparent
to persons skilled in the art. Of note, and as seen in the
drawings, it is contemplated according to the present disclosure
that a conventional ball bearing drawer slide or any slide
available may be used as a horizontal support 311.
[0099] A vertical shelves support 302 also includes "box-like"
beams 304, advantageously detachably mounted to moving member 307
associated with horizontal support 301. Beam 304 is sized and
dimensioned to accommodate horizontal movement of members 306 by
ways of a ball bearings member. The horizontal telescopic
functionality of horizontal support 301 allows shelves, which are
mounted on moving member 306, to travel upward and downward along
beam 304. The telescopic functionality may be achieved by balls,
rollers, wheels, and other ways as will be readily apparent to
persons skilled in the art. Of note, and as seen in the drawings,
it is contemplated according to the present disclosure that a
conventional ball bearing drawer slide or any slide available may
be used as a vertical shelves support 302.
[0100] Thought the drawings depict a "box-like" beams members,
alternative cross-sectional configurations are contemplated, e.g.,
cross-sections that are, in whole or in part, elliptical,
trapezoidal, etc., as may be desired to achieve aesthetic effects
and/or to accommodate external considerations, e.g., space
constraints or manufacturing efficiencies.
[0101] Turning to FIG. 3.1 a side view of a shelf assembly which
mounted on side wall 312 is provided. The shelf assembly comprises
of a stack of shelves (310) mounted on a slide system 300. The
stack of shelves, which include shelf 306, 307, 308, and 309,
mounted on moving member 306 associated with upright support 302
with the shelves 310 in the upward position. FIG. 3.2 and FIG. 3.3
are also a side view of a shelf assembly which mounted on side wall
312 is provided. As seen in FIG. 3.2 and 3.3 shelves 310 are in the
outward and downward position respectively.
[0102] In operation, exemplary shelving system 300 operates to
facilitate repositioning of shelves 306, 307, 308, and 309 to an
access position by permitting outward horizontal motion of the
shelves relative to back wall 322, as shown in FIG. 3.2, and
vertical movement of the shelves relative to horizontal support 301
as seen in FIG. 3.3. Such horizontal motion of the shelves is
accomplished by way of telescoping functionality associated with
horizontal support 301. By moving first the shelves outwardly,
members 305 and 306 are travel outward within beam 303 such as the
shelves over traveled past side wall 312. Once first shelves are
outwardly positioned, downward vertical movement of the shelves may
be accomplished by way of upright support 302. Stated differently,
outward horizontal movement of the shelves creates clearance
relative to lower shelves not shown here or objects located below
not shown here either, thereby permitting the shelves to move
downward to an access position.
[0103] A leading wheel and a leading rail, for securing the shelves
at upper rest position and guiding them when in motion from upper
position to lower position, may be incorporated in slide system and
shelving system 300 or in other slide system described thereafter,
e.g., as disclosed in Zackary Engel prior arts such as U.S. Pat.
No. 5,799,588 the contents of which are incorporated herein by
reference.
[0104] Referring now to FIGS. 4-4.4, a forth exemplary shelving
system 400 according to the present disclosure is schematically
depicted. As seen in FIGS. 4-4.4, exemplary Slide System 400 is
almost identical in structure and operation to exemplary Slide
System 300. As seen in FIG. 4, however, the moving member 406
associated with the upright support 404 is shorter than its
corresponding member 306 which associated with exemplary 300.
Unlike exemplary 300, and as will hereinafter be described, the
configuration of upright support 402 allows member 406 to travel
only within beam 404.
[0105] Turning to FIG. 4.1 a side view of a shelf assembly which
mounted on side wall 412 is provided. The shelf assembly comprises
of an upper stack of shelves 415 mounted on a slide system 400, and
above a second stack of lower selves 420 mounted on back wall. The
upper stack of shelves, which include shelf 407 and 408, mounted on
moving member 406 associated with upright support 402, with the
upper shelves in the upward position. As will hereinafter be
described, lower shelves 420 are shorter than the upper shelves 415
and mounted on the back wall so as to permit the upright support
402 to travel outward and away from lower shelves 420.
[0106] FIG. 4.2 and FIG. 4.3 are also a side view of a shelf
assembly which mounted on side wall 412 is provided. As seen in
FIG. 4.2 and 4.3 shelves 420 are in the outward and downward
position respectively.
[0107] In operation, the upper stack shelves 415 is moved out in
the direction of arrow A from a rest position (FIG. 4.2) along
horizontal support 401 and in line with the lower shelf 420. By
moving the upper shelf 415 out from the stack of shelves, the
telescoping support 404 is moved out from member 403, i.e.
over-traveled out and past the lower shelf 420. Indeed, the
telescoping functionality of element 401 described herein may be
achieved through slide elements, e.g., slides that facilitate
drawer functionality, that are commercially available in the
market. The upper shelf 415 is thus drawn out from the stack of
shelves sufficiently to permit the upper shelves 415 to move past
or in alignment with the lower shelf 420. After the upper shelf 415
is moved outward from the lower shelves 420, it is then moved
downward along the direction of arrow B (FIG. 4.3) to move the
upper shelf 415 in alignment with lower shelves 420 and to a
position where it can be accessed. As describe there before,
upright support 402 facilitates the vertical movement of shelves
415. As of note, upright support 402 may be fabricated, at least in
part, utilizing a conventional drawer slide. Alternatively other
members and arrangements of rollers may be incorporated to achieve
the vertical movement of upper shelves 415, as will be apparent to
persons skilled in the art.
[0108] Not shown here, this and other slide systems disclosed in
the present invention may support lower stack of shelves and allows
upper shelves to trade place with lower shelves. In this case, this
slide includes one or more telescopic arms which support stack of
upper shelves. The telescopic arms are vertically mounted on
horizontal slide(s) to facilitate an outward and inward movement of
the upper shelves. This slide also includes an upright rail to
mobilize a stack of lower shelves upwardly and downwardly by way of
a roller. Pulley and telescopic bar arrangement connect the stack
of upper shelves to the stack of lower shelves such as a vertical
movement of the upper shelves causes a corresponding opposite
movement of a lower shelf. After an upper shelf or shelves are
moved horizontally by way of the slide and vertically to or past a
lower shelf by way of the telescopic arms, the upper shelf or
shelves may be moved back into alignment with the lower shelf. In
this arrangement, the upper shelf or shelves can thereby become
positioned below the lower shelf to permits easy access to the
upper shelf or shelves.
[0109] Specifically, when the upper shelf 415 is moved down, the
lower shelf 420 may remain in position or may be conversely moved
up by means of pulley arrangements, by other means such as the gear
and leg arrangement, in a way apparent to persons skilled in the
art, or as disclosed in Zackary Engel prior arts such as U.S. Pat.
No. 5,799,588 and U.S. patent application 2003-0189021 the contents
of which are incorporated herein by reference. In such case, and as
describe in Engel's prior art, the first shelves 415 is lowered
past the second shelves 420, the second shelves 420 are
automatically raised past the first shelves 415 to effectively
trade positions therewith. Thereafter, the first shelves 415 can be
raised up, and the second shelves 429 automatically lowered, such
that the first and second sets of shelves are returned to their
original relative positions.
[0110] Turning to FIG. 4.4, a three dimensional embodiment of
shelving system 475 is illustrated. In this embodiment, a right
slide system 450 similar to those in the previous embodiment (FIG.
4.3) is provided with similar reference numerals plus 50. The right
slide 450 is mounted on cabinet side wall 462. As seen in FIG. 4.4,
the shelving system 460 also includes a left slide system 451'
similar to the right one with similar reference numerals plus
apostrophes. The left slide is mounted on cabinet side wall 462'.
Finally as seen in FIG. 4.4, upper shelves 465 is mounted on both
slide system 450 and 450', and lower shelves 470 is mounted on the
cabinet back wall 463.
[0111] In operation shelving system 475 is similar to shelving
system 400 as described there above.
[0112] Referring now to FIGS. 5-5.2, a fifth exemplary shelving
system 500 according to the present disclosure is schematically
depicted. As seen in FIGS. 5-5.2, exemplary Slide System 500 is
almost identical in structure and operation to exemplary Slide

with the upper shelves in the upward position. As seen in FIG.
5-5.2, upright support 502 is mounted on members 507 and 527
associated with horizontal support 501 and 521 respectively. As
will hereinafter be described, lower shelves 520 are shorter than
the upper shelves 515 and mounted on the back wall so as to permit
the upright support 502 to travel outward and away from lower
shelves 520.
[0115] FIG. 5.2 is also a side view of a shelf assembly which
mounted on side wall 512. As seen in FIG. 5.2 shelves 520 are in
the outward and downward position.
[0116] In operation shelving system 500 is similar to prior

[0117] Referring now to FIGS. 6-6.3, a sixth exemplary shelving
system 600 according to the present disclosure is schematically
depicted. As seen in FIGS. 6-6.3, exemplary Slide System 600 is
almost identical in structure and operation to exemplary Slide
System 500. In this embodiment, a slide system 600 is similar to
those in the previous embodiment 500 is provided with similar
reference numerals plus 100. As seen in FIG. 6, however, exemplary
600 includes an additional upright support 632. In this embodiment,
the rear upright support 602 is similar to the front upright
support 632 with similar reference numerals plus 30. I addition, as
seen in FIG. 6, members 607 and 605 associated with horizontal
support 601, and members 627 and 625 associated with horizontal
support 621, are relatively longer than those depicted in prior
slide systems so as to support the additional front upright support
632. The added upright support potentially provides enhanced
stability to exemplary storage systems shown in FIG. 5-5.2.
[0118] As seen in FIG. 6, slide system 600 includes upright support
602 and upright support 632 mounted on horizontal supports 601 and
621. As seen in FIG. 6, upright support 602 and 632 and horizontal
supports 601 and 621 are similar in configuration and operation to
uprights and horizontal supports describe in prior slide systems
Turning to FIG. 6.1 a side view of a shelf assembly which mounted
on side wall 612 is provided. The shelf assembly comprises of an
upper stack of shelves 607 and 608 mounted on a slide system 600,
and above a second stack of lower selves 609 and 610 mounted on
back wall not shown here. The upper stack of shelves, which include
shelf 607 and 608, are mounted on moving member 606 and 636
associated with upright support 602 and 632 respectively, with the
upper shelves in the upward position. As seen in FIG. 6-6.2,
upright support 602 and 632 are mounted on members 607 and 627
associated with horizontal support 601 and 621 respectively. As
will hereinafter be described, lower shelves 609 and 610 are
shorter than the upper shelves 607 and 608 and mounted on the back
wall so as to permit the upright support 602 and 632 to travel
outward and away from lower shelves 609 and 610.
[0119] FIG. 6.2 is also a side view of a shelf assembly which
mounted on side wall 612. As seen in FIG. 6.2 shelves 609 and 610
are in the outward and downward position.
[0120] Turning to FIG. 6.3, a three dimensional embodiment of slide
system 650 mounted on right side wall 662 is illustrated. In this
embodiment, a right slide system 650 similar to those in the
previous embodiment 600 is provided with similar reference numerals
plus 30.
[0121] In operation shelving system 600 is similar to prior
shelving system as described there above.
[0122] Referring to FIGS. 7-7.4, exemplary 700 shows a compact
rotary damper which are mainly including any sprocket wheel and any
damper.
[0123] As seen in FIG. 7.1, a sprocket wheel 701 is mounted on a
support object 705 with a suitable connection as known to those
skilled in this art. A mini damper 702 is also mounted on support
object 705 by the pressure tube connector 707 and on sprocket wheel
701 by the piston rod connector 706, such as the. Importantly, the
connection fitting allows the sprocket wheel 701 to rotate, and to
the dumper piston rod 703 and pressure tube 704 to pivot.
[0124] FIG. 7.4 is a side view of exemplary 700 where a sprocket
wheel coacts with a damper.
[0125] In operation, and as seen in FIG. 7.1-7.3, when the sprocket
wheel 701 rotates clockwise and counter clockwise (arrow A), the
piston rod 704 moved in and out of the pressure tube 703. The
movement of the piston 704, which displaces a filling medium
through a valve system inside the pressure tube, produces the
damping force. The dumping force in return influence the nature of
the rotation of the sprocket wheel 701 and thus reduce the speed of
the wheel.
[0126] Referring now to FIGS. 7.5, a second exemplary dumping
system 710 according to the present disclosure is schematically
depicted. Using one dumper might leave segments of the wheel
rotation with little or no damping while the piston will be in a
transition period from compression to extension. This can be
rectified by the use of two wheels and two dampers with the dampers
offset by 90 degrees.
[0127] As seen in FIG. 7.5, exemplary 710 includes two dumping
system which coact together through the sprocket wheels 711 and
711'. Also, as seen in FIG. 7.5, piston rods 714 and 714' are
mounted on sprocket wheel 711 and 711' at 90 degrees relative to
each other (dashed lines 719). As seen in FIGS. 7.5, exemplary
dumping system 710 is almost identical in structure and operation
to exemplary Slide System 700 seen in FIG. 7-7.4. Dumping system
710, which is similar to those in the previous embodiment 700, is
provided with similar reference numerals plus 10. Likewise, the
additional dumping system, which is similar to the fist one, is
provided with similar reference numerals plus apostrophe.
[0128] In operation damper system 710 is similar to damper system
700 described there above.
[0129] Referring now to FIGS. 7.6, a first possible application of
the damper system is provided. As seen in FIG. 7.6, exemplary
dumping system 720 is almost identical in structure and operation
to exemplary Slide System 710 seen in FIG. 7.5. Dumping system 720,
which is similar to those in the previous embodiment 710, is
provided with similar reference numerals plus 10. Member 726
represents an upright support such as upright support 654 seen in
FIG. 6.3. In addition, member 725 represents a slide member and
shelves support member such shelves support 656 seen in FIG.
6.3.
[0130] As seen in the FIG. 7.6, two sprocket wheels 721 and 721'
and two dampers 722 and 722' mounted on the shelves support member
725. Shelves support member 725, which is mounted inside upright
support 726, is capable to slide upward and downward by way of
wheels 727 and 728 and sprocket wheels 721 and 721'. Gear 725 is
mounted on upright support 726 and engages with the sprockets wheel
teeth.
[0131] In operation, and as seen in FIG. 7.6 and prior exemplary,
when shelves support slide downward sprocket wheels 721 and 721',
which engage with the rack, rotate. Accordingly, piston rod 724 and
724' moved in and out of the pressure tube 723 and 723'
respectively. The movement of piston rod 724 and 724' produces the
damping force. The dumping force in return influence the nature of
the rotation of the sprocket wheels 721 and 721' and thus permit
reliable and efficient repositioning and dampening of objects which
are load on shelves support member 725.
[0132] Referring now to FIGS. 7.7, a second possible application of
the damper system is provided. As seen in FIG. 7.7, exemplary
dumping system 730 is similar in structure and operation to prior
exemplary an need no farther descriptions.
