Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to and the benefit of U.S.
provisional patent application Ser. No. 60/790,747, which was filed
on Apr. 10, 2006 and entitled TABLE, which is incorporated by
reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention generally relates to furniture and, in
particular, to tables.
[0004] 2. Description of Related Art
[0005] Conventional tables are used for a variety of purposes and
come in a wide array of designs. In some situations, it is
desirable to have a smaller table for personal or individual use.
These smaller-sized tables intended for use by a single person may
be referred to as a personal table. For example, persons living in
a small space, such as a studio apartment, may choose to use a
smaller or personal sized table on which to dine or perform tasks
such as reading, working or writing. These smaller or personal
sized tables can also be used to hold objects such as computers,
televisions and other electronic equipment.
[0006] Known tables often include a table top that is permanently
fixed in a particular location and configuration. In addition,
known tables typically include a table top that is disposed in a
level orientation in which the upper surface of the table is
generally parallel to a support surface such as the ground or
floor. A level orientation, however, may not be best suited for
certain uses of the table.
[0007] Known tables may also be adjustable. For example, the height
of some known tables may be adjustable. Additionally, the
orientation of the table top for some known tables may be
adjustable. Disadvantageously, it may be rather time consuming and
difficult to adjust the height or orientation of the table top of
some conventional tables. For example, adjusting the orientation of
the table top of some conventional tables may require the loosening
and tightening of a knob or fastener, which can make adjusting the
orientation of the table tops difficult, awkward and time
consuming.
BRIEF SUMMARY OF EMBODIMENTS OF THE INVENTION
[0008] One aspect is a table that may include a table top that is
movable between an extended or use position and a collapsed or
storage position. The table may also include a frame that is sized
and configured to support the table top, and the frame may be
movable between an extended or use position and a collapsed or
storage position. With the table top and the frame in the collapsed
positions, the table may advantageously be disposed in a relatively
compact. Significantly, this may allow the table to be stored in a
smaller area and it may allow the table to be more efficiently
shipped in smaller packaging.
[0009] Another aspect is a table that may include a table top and a
frame which can be separately movable between extended and
collapsed positions. For example, when storage of the table is
desired, the table top may be moved from the extended position to
the collapsed position and then a portion of the frame may be moved
from the extended position to the collapsed position. When use of
the table is desired, the lower portion of the frame may be moved
to back to its extended position and then the table top may be
moved back to its extended position. Advantageously, the table top
and the frame may be moved between the collapsed and extended
positions in any desired order, which may increase the potential
uses of the time. In addition, the table top and frame may be
simultaneously moved between the collapsed and extended positions,
if desired.
[0010] Still another aspect is a table that may include one or more
wheels, which may be sized and configured to allow the table to be
quickly and easily moved. Significantly, the wheels may be used
when the table top and/or frame are in the extended or use
positions. For example, when the table top and frame are in the
extended positions, the wheels may be used to allow the table to be
quickly and easily moved from one location to another location. On
the other hand, the wheels may allow the table to be quickly and
easily moved when the table top and frame are in the collapsed
positions. One or more of the wheels may also be spaced apart from
a support surface when the table top and/or frame are in the
extended or use positions. For instance, the wheels may be spaced
apart from the support surface when the table top and frame are in
the extended and/or use positions to prevent the table from
inadvertently moving.
[0011] Yet another aspect is a table that may include table top
with a first section and a second section. The first and second
sections are preferably movable relative to each other to allow the
configuration of the table top to be adjusted. For example, the
second table top section may be sized and configured to rotate,
pivot, tilt and/or move relative to the first table top section. In
addition, both the first and second sections of the table top may
be adjustable. For instance, the first and second sections may be
sized and configured to rotate, pivot, tilt and/or move in one or
more directions. Advantageously, if the table top includes movable
sections, then that may allow the table to accommodate a variety of
different users and be used for a number of purposes and
functions.
[0012] A further aspect is a table that may include a table top
with first and second sections in which the second section is sized
and configured to rotate, pivot, tilt and/or move between a first
position in which the first and second table top are generally
aligned and a second position in which the second table top section
is positioned at an angle relative to the first table top section.
Advantageously, when the second table top section is in the second
position, the first and second table top sections may be positioned
for different uses. For example, the first table top section could
be positioned in a generally level or horizontal position and
pencils, pens, rulers, books and/or other items may rest upon this
section of the table top. The second table top section, however,
may be disposed at an angle relative to the first table top
section. This may allow, for example, the second section to support
items at an angle. Advantageously, this may allow items such as a
laptop computer to be disposed in an ergonomically beneficial
position. Of course, the table top sections may be disposed in
other positions and may be used for a variety of other purposes and
functions.
[0013] A still further aspect is a table that may include a table
top with first and second sections in which the second table top
section may be sized and configured to rotate, pivot, tilt and/or
within a limited range relative to the first table top section.
Limiting the movement of the second table top section relative to
the first table top section may advantageously help ensure that the
second table top section is used for a particular, purpose or
function. For example, if the movement of the second table top
section is limited to about 15 degrees relative to the first table
top section, then that may help prevent items from unintentionally
sliding off the table top. In addition, limiting the movement of
the table top sections may allow items such as laptop computers to
be disposed in ergonomically beneficial positions. It will be
appreciated that the movement of the table top sections need not be
limited to about 15 degrees. In contrast, the table top sections
may be limited to larger or smaller angles or positions depending,
for example, upon the intended use of the table or table top
sections.
[0014] Yet another further aspect is a table that may include a
table top with first and section sections in which the table top
sections may be sized and configured to rotate, pivot, tilt and/or
move without tightening and/or loosening of a knob or fastener. For
example, the table top may include a ratcheting mechanism that is
sized and configured to allow the position of the second table top
section to be incrementally adjusted without tightening and/or
loosening a knob or fastener. In addition, one or more portions of
the table, such as the frame or table top, may help create a
friction, snap and/or interference fit that allows the position of
the second table top section to be incrementally adjusted without
tightening and/or loosening a knob or fastener.
[0015] Another aspect is a table that may be adjustable in height.
In particular, the table top that may be sized and configured to be
movable between a plurality of different heights. For example, the
table top may move between a first position in which the table top
is positioned at a first height and a second position in which the
table top is positioned at a second height.
[0016] Still another aspect is a table that may include a height
adjustment mechanism which is sized and configured to adjust the
height of the table top between the plurality of different heights.
The height adjustment mechanism is preferably sized and configured
to be operated with one hand or one foot. For example, the height
adjustment mechanism may include a trigger (such as a button,
lever, handle or the like) that may be operated with one hand to
lock and/or unlock the table top at a desired height. Also, for
example, the height adjustment mechanism may include a trigger
(such as a foot pedal) that may be operated with one foot to lock
and/or unlock the table top at a desired height.
[0017] Yet another aspect is a table that may include a height
adjustment mechanism which is sized and configured to adjust the
height of the table top in a generally smooth fashion. For example,
the height adjustment mechanism may include a spring (such as a gas
spring, a coiled spring or the like) which may advantageously allow
the height of the table top to be adjusted in a generally smooth
fashion.
[0018] A further aspect is a table that may have a relatively
small-sized table top that is designed for use by a single person.
This type of table that is intended for use by an individual may be
referred to as a personal table, but it will be appreciated that
more than one person could use the table if desired.
Advantageously, the personal table may be relatively small and
light-weight, which may make the table relatively easy to move and
transport. Significantly, because the table may be sized and
configured for personal use, it may not take up unnecessary space
or provide a large amount of unused space. Therefore, the personal
table may provide ample space for a single user without requiring a
large area or wasting unnecessary space.
[0019] A still further aspect is a table that may be used for a
wide variety of different situations, purposes and uses. For
example, the table may be used for supporting a television,
computer, sewing machine, microwave, lamp, luggage and the like.
The table can also be used for a wide variety of other uses such as
a bedside table, coffee table, night stand, desk, shop table and
the like. Further, the table can be used while performing a wide
variety of tasks such as reading, writing, studying, working, etc.
Thus, the table can be used in a number of different environments
and it can perform numerous different tasks.
[0020] Yet another further aspect is a table that may include a
table top constructed from lightweight material so that the table
is easily portable and can be readily lifted and moved by a single
person. Desirably, the table top is constructed from blow-molded
plastic, such as high density polyethylene. The blow-molded plastic
table top may provide a relatively rigid, high-strength structure
that is capable of withstanding repeated use and wear.
Advantageously, the blow-molded table top may be easily
manufactured and formed into the desired size and shape. The
blow-molded plastic table top preferably includes a hollow interior
portion, which may help form the relatively lightweight table top.
Advantageously, the blow-molded table top may include one or more
features that are integrally formed in the table top as part of a
unitary, one-piece structure. For example, the bottom of the table
top may include one or more grooves, channels and the like, which
may be sized and configured to receive and/or retain a portion of
the table such as the legs and/or frame.
[0021] Another aspect is a table that may include a table top and
one or more legs that are sized and configured to support the table
top at a desired height. The legs are preferably offset towards one
side of the table top. Advantageously, because the legs are not
placed in the center of the table, that may provide increased
legroom for the user. This also may allow the table top to be
positioned closer to the body of the user, which may be more
convenient for the user.
[0022] These and other aspects, features and advantages of the
present invention will become more fully apparent from the
following detailed description of preferred embodiments and
appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0053] The present invention is generally directed towards a table.
The principles of the present invention, however, are not limited
to tables. It will be understood that, in light of the present
disclosure, the table disclosed herein can be successfully used in
connection with other types of furniture.
[0054] Additionally, to assist in the description of the table,
words such as top, bottom, front, rear, right and left may be used
to describe the accompanying figures, which are not necessarily
drawn to scale. It will be appreciated, however, that the table can
be located in a variety of desired positions--including various
angles, sideways and even upside down. A detailed description of
the table now follows.
[0055] As shown in FIGS. 1-2, an exemplary table 10 is preferably a
relatively small-sized table that is designed for use by a single
person. This type of table that is intended for use by an
individual may be referred to as a personal table, but it will be
appreciated that more than one person could use the table 10 if
desired. Advantageously, the personal table 10 may be relatively
small and light-weight, which may make the table relatively easy to
move and transport. Significantly, because the table 10 may be
sized and configured for personal use, it may not take up
unnecessary space or provide a large amount of unused space.
Therefore, the personal table 10 may provide ample space for a
single user without requiring a large area or wasting unnecessary
space. In addition, the personal table 10 can be used for a wide
variety of different situations and uses such as a table for
supporting a television, computer, sewing machine, microwave, lamp,
luggage and the like. The table 10 can also be used for a wide
variety of other uses such as a bedside table, coffee table, night
stand, desk, shop table and the like. Further, the table 10 can be
used while performing a wide variety of tasks such as reading,
writing, studying, working, etc. Thus, the personal table 10 can be
used in a number of different environments and it can perform
numerous different tasks. It will be appreciated, however, that the
table 10 need not be a personal table and that the table may have a
variety of other suitable shapes, sizes, configurations and
arrangements.
[0056] As shown in FIGS. 1-2, the table 10 may include a table top
12. The table top 12 may be constructed from a lightweight material
so that the table 10 is easily portable and can be readily lifted
and moved by a single person. Desirably, the table top 12 is
constructed from blow-molded plastic, such as high density
polyethylene. The blow-molded plastic table top 12 may provide a
relatively rigid, high-strength structure that is capable of
withstanding repeated use and wear. Advantageously, the blow-molded
table top may be easily manufactured and formed into the desired
size and shape. The blow-molded plastic table top 12 preferably
includes a hollow interior portion, which may help the table top to
be relatively lightweight. It will be appreciated, however, that
the table top 12 may be constructed using other suitable materials
and/or other processes.
[0057] The table 10 may also include a frame 14 that is sized and
configured to support the table top 12. The frame 14 may include an
upper portion 16, a lower portion 18 and an intermediate portion 20
disposed between the upper and lower portions of the frame. The
frame 14 and its components are preferably constructed from metal,
such as steel. It will be appreciated, however, that the frame 14
and its components may be constructed from other suitable
materials.
[0058] The intermediate portion 20 of the frame may include one or
more legs and the legs may be offset towards one side of the table
top 12. Advantageously, if the legs are not placed in the center of
the table 10, that may provide increased legroom for the user. This
may also allow the table top 12 to be positioned closer to the body
of the user, which may be more convenient for the user. It will be
appreciated, however, that the legs and the intermediate portion 20
need not be offset towards one side of the table top 12 and may be
positioned in any desired location.
[0059] As shown in FIGS. 3-6, the table top 12 and the frame 14 may
be movable between an extended or use position and a collapsed or
storage position. With the table top 12 and the frame 14 in the
collapsed or storage position, the table 10 may advantageously be
relatively compact, which may allow the table to be stored in a
smaller area. In addition, when in this relatively compact
position, the table 10 may be more efficiently shipped in smaller
packaging.
[0060] In further detail, when storage of the table 10 is desired,
the lower portion 18 of the frame 14 may be moved from the extended
position shown in FIGS. 1-2 to the collapsed position shown in
FIGS. 3-4, and then the table top 12 and the upper portion 16 of
the frame may be moved from the extended position shown in FIGS.
3-4 to the collapsed position shown in FIGS. 5-9. When use of the
table 10 is desired, the table top 12 and the upper portion 16 of
the frame 14 may be moved to back to their extended positions, and
then the lower portion 18 of the frame may be moved back to its
extended position.
[0061] In another instance, when storage of the table 10 is
desired, the table top 12 and the upper portion 16 of the frame 14
may be moved from the extended position to the collapsed position,
and then the lower portion 18 of the frame may be moved from the
extended position to the collapsed position. In this instance, when
use of the table 10 is desired, the lower portion 18 of the frame
14 may be moved to back to its extended position, and then the
table top 12 and the upper portion 16 of the frame may be moved
back to their extended positions. It will be appreciated that the
various portions of the table 10 may be moved in different
sequences and arrangements depending, for example, upon the size,
shape, configuration and arrangement of the table.
[0062] To facilitate the movement of the table top 12 and the frame
14 between the extended and collapsed positions, the portions 16,
18, 20 of the frame may be pivotally or movably interconnected. For
example, an upper part of the intermediate portion 20 may be
pivotally or movably connected to the upper portion 16 of the frame
14, and a lower part of the intermediate portion may be pivotally
or movably connected to the lower portion 18 of the frame. The
portions 16, 18, 20 of the frame may be pivotally or movably
interconnected using one or more brackets, connectors, fasteners,
hinges, locking assemblies and/or any other suitable means and
structures.
[0063] If desired, some or all of the components of the table top
12 and the frame 14 may be separately movable between the extended
and collapsed positions. In addition, some or all of the components
of the table top 12 and the frame 14 may be sized and configured to
be collapsed before each other, after each other, or at the same
time depending, for example, the particular configuration of the
table 10. It will be appreciated that the components of the table
top 12 and the frame 14 need not be separately movable between the
extended and collapsed positions.
[0064] As shown in FIGS. 1-2, the table top 12 and the upper and
lower portions 16, 18 of the frame 14 may be aligned in generally
parallel planes when the table top and the frame are in the
extended positions. In addition, when the table top and the frame
are in the extended positions, the intermediate portion 20 may be
in a generally perpendicular orientation relative to the table top
12 and/or the upper and lower portions 16, 18 of the frame 14.
[0065] As shown in FIGS. 5-9, the table top 12 and the upper, lower
and intermediate portions 16, 18, 20 of the frame 14 may be aligned
in generally parallel planes when the table top and the frame are
in the collapsed positions. This may advantageously allow the table
10 to be stored in a smaller area and/or to be more efficiently
shipped in smaller packaging. It will be appreciated, however, that
the table top 12 and the upper, lower and intermediate portions 16,
18, 20 of the frame 14 may be disposed in other suitable relative
positions when the table top and the frame are in the collapsed
positions.
[0066] Desirably, some or all of the components of the table top 12
and the frame 14 may be locked in the extended and/or collapsed
positions. For example, as shown in FIG. 2, the table 10 may
include a first locking assembly 22 and a second locking assembly
24. The first locking assembly 22 may be sized and configured to
lock the table top 12 and the upper portion 16 of the frame 14 in
the extended positions, and the second locking assembly 24 may be
sized and configured to lock the lower portion 18 of the frame in
the extended position. The locking assemblies 22, 24 are preferably
sized and configured to automatically lock the table top 12 and
upper and lower portions 16, 18 in the extended positions. The
locking assemblies 22, 24 may include triggers 26, 28,
respectively, (such as a button, lever, handle, or the like) that
may be used to unlock the locking assemblies to permit the table
top 12 and/or upper and lower portions 16, 18 to be moved. It will
be appreciated, however, that the locking assemblies 22, 24 need
not be automatically lockable and that the triggers 26, 28 may be
used to manually lock the locking assemblies. It will also be
appreciated, that the table 10 does not require any locking
assemblies 22, 24.
[0067] The table 10 may also include wheels 30, 32, 34, 36, which
may be sized and configured allow the table to be quickly and
easily moved to a desired location. The wheels 30, 32, 34, 36 may
be sized and configured to engage a support surface, such as the
ground or floor, when the table 10 is in an extended or use
position, as shown in FIGS. 1-2. In addition, when the table 10 is
in a collapsed or storage position, the wheels 30, 32 may engage
the support surface while the wheels 34, 36 are spaced apart from
and/or disengage the support surface, such as shown in FIGS. 5-9.
However, the wheels 30, 32 may be spaced apart from and/or
disengage the support surface when the table 10 is in the extended
or use position or when the table is in the collapsed or storage
position depending, for example, upon the particular configuration
and/or intended use of the table 10.
[0068] The wheels 30, 32, 34, 36 may be connected to various
portions of the frame 14. For example, the wheels may be connected
to the lower portion 18 of the frame and/or the intermediate
portion 20 of the frame. The wheels 30, 32, 34, 36 may also be
connected to other suitable portions of the table 10. It will be
appreciated, however, that the table 10 does not require any
wheels.
[0069] As shown in FIGS. 10-11, the height of the table 10 may be
adjustable. In particular, the height of the table top 12 may be
movable between a plurality of heights. For example, the table top
12 may be sized and configured to move between a first position in
which the table top is positioned for use at a first height and a
second position in which the table top is positioned for use at a
second height. It will be understood that the table 10 and table
top 12 may be positioned at any desired height.
[0070] In further detail, the intermediate portion 20 of the frame
14 may include a height adjustment mechanism that is sized and
configured to adjust the height of the table top 12. In particular,
the height adjustment mechanism may increase or decrease the length
of the intermediate portion 20 to raise or lower the table top 12.
The height adjustment mechanism may advantageously be sized and
configured to adjust the height of the table top 12 in a generally
smooth fashion. For example, the height adjustment mechanism may
include a spring (such as a gas spring, a coiled spring or the
like) which may advantageously help adjust the length of the
intermediate portion 20 in a generally smooth fashion. It will be
appreciated that the height of the table top 12 may also be
adjusted using other processes and structures, that the height of
the table top toes not have to be adjusted in a generally smooth
fashion.
[0071] The height adjustment mechanism may be sized and configured
to be operated with one foot or one hand. For example, the height
adjustment mechanism may include a trigger (such as a foot pedal)
that may be operated with a foot to lock and/or unlock the table
top 12 at a height. Also, for example, height adjustment mechanism
may include a trigger (such as a button, lever, handle or the like)
that may be operated with one hand to lock and/or unlock the table
top at a height. In addition, the hand-operated trigger may be
sized and configured to be grasped in order to help lift or lower
the table top.
[0072] As shown in FIG. 1, the height adjustment mechanism may
include a push button 38. The push button 38 may engage any
plurality of openings 40 to help lock the table top 12 at a desired
height. It will be appreciated, however, that the height adjustment
mechanism does not require push buttons 38, openings 40, triggers
or springs and that the height adjustment mechanism may include a
variety of other suitable structures with appropriate components.
It will also be appreciated that the table 10 does not require a
height adjustment mechanism.
[0073] As shown in FIGS. 1-2, the table top 12 may include a
plurality of table top sections, such as a first table top section
42 and a second table top section 44. The second table top section
44 may be sized and configured to rotate, pivot, tilt and/or move
relative to the first table top section 42. Preferably, the first
and second table top sections 42, 44 are movable when the table top
12 is in the extended or use position, but the table top sections
could also be movable when the table top is in the collapsed
position.
[0074] Advantageously, the movable table top sections may allow the
table 10 to be used for a number of different functions and uses.
In addition, the movable table top sections may accommodate a
variety of users. The table top sections may also be movable
between a number of different configurations and arrangements.
Further, one or more of the table top sections may be movable and
the different sections of the table top may be movable in the same
or different directions.
[0075] For example, as shown in the accompanying figures, the
second table top section 44 may be sized and configured to rotate,
pivot, tilt and/or move between a first position in which the first
and second table top sections 42, 44 are generally aligned (as
shown in FIGS. 1-2) and a second position in which the second table
top section is positioned at an angle relative to the first table
top section (as shown in FIGS. 12-14 and in FIGS. 15-17).
Advantageously, when the second table top section 44 is in the
second position, the table top sections 42, 44 may be positioned
for different uses. For example, the first table top section 42
could be positioned in a generally level or horizontal position to
hold pencils, pens, rulers, books and the like. On the other hand,
the second table top section 44 could be positioned at an angle,
for example, to support a laptop computer in an ergonomically
beneficial position. Of course, the table top sections 42, 44 may
be positioned in other positions and may be used for other suitable
purposes.
[0076] The table top section 44 may be sized and configured to
rotate, pivot, tilt and/or move within a limited range of angles
relative to the table top section 42. Limiting the movement of the
table top section 44 relative to the table top section 42 may
advantageously help to ensure the table top section 44 provides a
working surface that accommodates intended uses. For example, as
shown in FIGS. 14 and 17, the movement of the table top section 44
is preferably limited to an angle A of about fifteen degrees
relative to the table top section 42, which may help the table top
section 44 support a laptop computer while advantageously providing
various ergonomically beneficial positions for the laptop.
[0077] If desired, the movement of the table top sections 42, 44
may be limited. For example, the movement of the second table top
section 44 may be limited to an angle A of about ten, fifteen,
twenty, twenty-five, thirty degrees or more relative to the first
table top section 42 depending, for example, upon the particular
intended use of the second table top section. Thus, where one or
more of the table top sections are sized and configured to rotate,
pivot, tilt and/or move, the movement of the table top sections may
be limited to a specific range, which may be dependent upon the
intended use of the table 10. Thus, it will be appreciated that the
range of movement of the table sections may be larger or smaller
than ten or thirty degrees. Therefore, for example, it will be
appreciated that the movement of the second table top section 44
relative to the first table top section 42 need not be limited to
about fifteen degrees or any other angle. It will also be
appreciated that the second table top section 44 may be positioned
at greater or lesser angles relative to the table top section 42,
if desired.
[0078] The frame 14 may be sized and configured to facilitate the
movement of the second table top section 44 relative to the first
table top section 42. For example, the upper portion 16 of the
frame 14 may include supports, such as brackets, tubes, rods and/or
other supports. The supports may be connected to the table top
sections 42, 44 and the supports may be movable relative to each
other to facilitate the movement of the second table top section 44
relative to the first table top section 42. In further detail, as
shown in FIGS. 18-19, the upper portion 16 of the frame 14 may
include a first set of supports 46, 48 and a second set of supports
50, 52, and the first and second sets of supports may be connected
to the first and second table top sections 42, 44, respectively.
The upper portion 16 of the frame 14 may also include a pivot 54,
which may be constructed from a tube, rod or the like, and the
pivot may have an elongated configuration. The second table top
section 44 and the supports 50, 52 may be pivotally, rotatably
and/or movably connected to the pivot 54, which may allow the
second table top section 44 and the supports 50, 52 to pivot,
rotate, tilt and/or move relative to the first table top section 42
and the supports 46, 48. It will be appreciated, however, that the
frame 14 does not require the supports 46, 48, 50, 52 or the pivot
54 and that the frame may include a variety of other components
with different configurations that may be used to facilitate the
movement of the second table top section 44 relative to the first
table top section 42.
[0079] As discussed above, the movement of the second table top
section 44 relative to the first table top section 42 may be
limited. For example, as shown in FIGS. 20-23, the table 10 may
include a locking assembly 55 that may be sized and configured to
secure the first and second table top sections 42, 44 in desired
positions and/or to limit the movement of the first and/or second
table top sections. In particular, the locking assembly 55 may
include a flange 56 and a pin 58. The flange 56 may be sized and
configured to engage the pin 58 to secure the table top section 44
in a desired position relative to the table top section 42. In
addition, the flange 56 may be sized and configured to engage the
pin 58 to limit the movement of the table top section 44 to a
limited range of angles relative to the table top section 42.
[0080] In further detail, the flange 56 may include a plurality of
receiving portions 60 that are sized and configured to engage the
pin 58 using, for example, a snap fit, a friction fit and/or an
interference fit. This may advantageously limit the relative
movement of the flange 56 and the pin 58. More significantly, this
may limit the relative movement of the table top sections 42, 44
because the flange 56 may be secured to table top section 42 and
the pin 58 may be secured to the table top section 44. For example,
the flange 56 may be connected to the pivot 54, which may be
connected to the table top section 42 by the brackets 46, 48; and
the pin 58 may be connected to a handle 62, which may be connected
to the table top section 44.
[0081] The handle 62 may be used to move the pin 58 among a variety
of positions to help facilitate the movement of the table top
section 44 from a first position relative to the table top section
42 to a second position relative to the table top section 42. In
particular, the pin 58 may initially engage a first receiving
portion 60, which may lock the table top section 44 in the first
position. When it is desired to move the table top section 44, the
handle 62 may be used to pull the pin 58 in a direction away from
the flange 56, causing the pin to disengage the first receiving
portion 60. When the pin 58 is disengaged from the first receiving
portion 60, the table top section 44 may be pivoted, rotated,
tilted and/or moved from the first position to the second position.
With the table top section 44 in the second position, the handle 62
may be used to push the pin 58 in a direction towards the flange
56, causing the pin to engage a second receiving portion 60 to
generally lock the table top section 44 at the second position.
[0082] As shown in FIG. 19, the locking assembly 55 may include a
biasing member 64, such as a spring. The biasing member 64 may be
sized and configured to bias the pin 58 in a direction towards a
locked position in which the pin engages the flange 56 and away
from an unlocked position in which the pin is disengaged from the
flange. In particular, the biasing member 64 may be sized and
configured to bias the handle 62 in a direction towards the flange
56 and, thus, to bias the pin 58 in a direction towards a locked
position in which the pin engages one of the receiving portions 60.
For example, the biasing member 64 may be sandwiched between a
portion of the handle 62 and a portion of the table top section 44.
When the handle 62 pulls the pin 58 away from a locked position to
an unlocked position, the biasing member 64 may be compressed
between the portions of the handle and the table top section 44.
When the handle 62 is released, the biasing member 64 may bias the
pin 58 into the locked position.
[0083] As shown in FIGS. 21-23, the receiving portions 60 may be
formed as part of a single, unitary opening or recess 66. This may
allow the pin 58 to move among the various receiving portions 60,
while at least a portion of the pin remains in the opening 66. In
particular, the opening 66 may include narrowed passageways 68 that
join adjacent receiving portions 60. Desirably, the pin 58 may be
sized and configured to pass through the narrowed passageways 68
when the pin is in an unlocked position. For example, an end 70 of
the pin 58 may have a generally tapered configuration and a
narrower portion of the generally tapered end may be sized and
configured to pass through a narrowed passageway when the pin is in
an unlocked position. This may allow a portion of the pin 58 to
remain in the opening 66 while the positioning of the second table
top section 44 is being adjusted.
[0084] Because the pin 58 may remain in the opening 66, the pin may
eventually contact, abut and/or engage the ends 72, 74 of the
opening when the second table top section 44 reaches a particular
position relative to the table top section 42. Advantageously, this
may prevent the second table top section 44 from moving past those
particular positions. For example, as shown in FIG. 22, the pin 58
may contact, abut and/or engage the end 72 of the opening 66 when
the table top section 44 reaches the position shown in FIG. 12.
Likewise, as shown in FIG. 23, the pin 58 may contact, abut and/or
engage the end 74 when the table top section 44 reaches the
position shown in FIG. 15. Thus, the opening may advantageously be
sized and configured to limit the movement of the second table top
section 44 to a limited range of movement relative to the first
table top section 42, as discussed above. It will be appreciated,
however, that the receiving portions 60 need not be formed as part
of a single, unitary opening or recess and that some or all of the
receiving portions may be formed as discrete openings, recesses
and/or other suitable features, if desired.
[0085] As discussed above, the table top section 44 may be locked
and unlocked in various positions without the tightening and
loosening of a knob or fastener. In particular, the locking
assembly 55 and/or other components of the table 10 may form a
friction fit, an interference fit and/or a snap fit that is sized
and configured to allow the position of the table top section 44 to
be incrementally adjusted without having to tighten and/or loosen a
knob or fastener. It will be appreciated, however, that the table
10 may include in other features that may allow the table top
section 44 may be locked and unlocked in various positions without
the tightening and loosening of a knob or fastener. For example,
the table 10 may include a ratcheting mechanism that is sized and
configured to allow the position of the table top section 44 to be
incrementally adjusted without having to tighten and/or loosen a
knob or fastener. It will be appreciated, however, that the
tightening and loosening of a knob or fastener may be used to lock
and unlock the table top section 44, if desired.
[0086] As shown in FIGS. 28-29, an exemplary wheel assembly 76 may
include a first wheel section 78, a second wheel section 80 and a
hub 82. The first wheel section 78 may include an opening 84
through which a support member 86, such as an axle, may extend.
With the support member 86 extending through the opening 84 in the
first wheel section 78, the hub 82 may be connected to the support
member using one fasteners 88 and then the wheel sections 80, 82
may be interconnected using fasteners 90.
[0087] Desirably, the wheel sections 78, 80 and the hub 82 may be
connected to an end the support member 86, which may eliminate any
need for a cap or cover for the end of the support member 86. It
will be appreciated, however, that the hub 82 may be connected to
other portions of the support member 86. It will also be
appreciated that the wheel sections 80, 82 and/or the hub 82 and
the support member 86 may be interconnected using any suitable
number and arrangement of fasteners or other suitable fasteners. It
will further be appreciated that the wheel sections 80, 82 and the
hub 82 may be connected using a snap fit, a friction fit, and/or an
interference fit; one or more adhesives and/or other suitable
means.
[0088] As shown in FIG. 28, one or both of the wheel sections 78,
80 may form at least a part of a receiving portion 92, which may
receive at least a portion of the hub 82. In particular, the
receiving portion 92 may be sized and configured to receive and
rotatably couple a ridge 94 formed in the hub 82, which may allow
the wheel sections 78, 80 to rotate about the hub. In addition, the
ridge 94 may be positioned between the wheel sections 78, 80, which
may desirably limit the movement of the wheel sections along the
length of the support member 86.
[0089] As shown in FIG. 29, the hub 82 may include a receiving
portion 96 that may be sized and configured to receive and/or
retain at least a portion of the support member 86. In particular,
the support member 86 may have a non-circular cross section and the
receiving portion 96 of the hub 82 may have a complementary
non-circular cross section that is sized and configured to engage
the support member using a snap fit, a friction fit and/or an
interference fit. For example, the support member 86 may have a
generally oblong configuration and the receiving portion 96 of the
hub 82 may have a generally oblong configuration. Desirably, this
may help prevent the hub 82 from rotating relative to the support
member 86. Moreover, this may allow the wheel assembly 76 to be
used in connection with a generally oblong support member 86. It
will be appreciated, however, that the support member 86 and the
receiving portion 96 may have any other suitable shape and/or
configuration.
[0090] As shown in FIG. 28, the support member 86 may be connected
to a pin 98. The pin 98 may extend through an opening 100 in the
hub 82 and into a receiving portion 102 formed in the wheel section
80. Desirably, the pin 98 may help provide additional support for
the hub 82 and/or the wheel section 80.
[0091] As best seen in FIGS. 1-2, the wheel sections 78, 80 may
help hide the attachment of the hub 82 to the support member 86.
This may advantageously help provide a cleaner, more appealing
visual appearance.
[0092] Although this invention has been described in terms of
certain preferred embodiments, other embodiments apparent to those
of ordinary skill in the art are also within the scope of this
invention. Accordingly, the scope of the invention is intended to
be defined only by the claims which follow.
