Abstract
A table may include a table top, legs, frame and one or more
bosses that are sized and configured to allow objects to be
attached to the table top. For example, the bosses may be sized and
configured to allow the frame to be connected to the table top. The
bosses may include a body and reinforcing members that extend
outwardly in non-radial directions. The table top may also include
ribs that are preferably disposed in a predetermined pattern. For
example, a portion of the table top may include a larger number or
density of ribs than another portion. In addition, the ribs may be
sized and configured to provide a table top with generally uniform
characteristics, such as a table top with generally uniform
strength and/or rigidity. The table may further be sized and
configured to move between a folded position and an unfolded
position, and a retainer may be sized and configured to secure the
table in the folded position.

[0002] This application also claims priority to and the benefit of
U.S. provisional patent application Ser. No. 60/864,766, which was
filed Nov. 7, 2006 and entitled TABLE WITH MOLDED TABLE TOP.
[0003] The disclosures of each of these applications are
incorporated by reference in their entireties.
BACKGROUND OF THE INVENTION
[0004] 1. Field of the Invention
[0005] The present invention generally relates to furniture and, in
particular, to tables.
[0006] 2. Description of Related Art
[0007] Some conventional tables include table tops constructed from
relatively heavy materials, such as metal or wood. These relatively
heavy table tops may undesirably increase the overall weight of the
tables making them more difficult to move and more expensive to
ship. In addition, metal and wood table tops may be susceptible to
rust and/or other damage.
[0008] Some conventional tables include a plastic table top and a
metal frame connected to the table top to help strengthen and
reinforce the table top. Unfortunately, the table top can be
damaged as the frame is connected.
BRIEF SUMMARY OF EMBODIMENTS OF THE INVENTION
[0009] A need therefore exists for a table that eliminates or
diminishes the disadvantages and problems described above.
[0010] One aspect is a table that may include a table top and one
or more legs. The legs may be movable between an extended or use
position and a collapsed or storage position. The table top may be
constructed from plastic and is preferably constructed using a
compression molding process. The table top, however, may be
constructed from other materials and/or other molding or
manufacturing processes, if desired. The table top may include a
pair of table top sections and the table may be folded in half for
more efficient storage and/or shipping.
[0011] Another aspect is a table that may include a table top
formed using a compression molding process, and the compression
molded table top may be constructed from plastic and/or other
suitable materials. The compression molded table top preferably
includes a first table top section and a second table top section,
which may be interchangeable. For example, the first and second
table top sections may be molded using the same mold or
substantially similar molds, which may allow the first and second
table top sections to be identical or substantially identical in
size, shape and/or configuration.
[0012] Still another aspect is a table that may include a molded
table top with one or more ribs. The molded table top preferably
includes a pattern of ribs and the pattern of ribs may include
portions that are different than other portions. For example, the
table may include a frame connected to the table top and the
pattern of ribs may be denser or spaced closer together proximate a
central portion of the table top. The ribs may also be spaced
closer together the farther the ribs are spaced from the frame.
Advantageously, this may allow the ribs and/or frame to be sized
and configured to provide a table top with generally consistent
strength and/or rigidity. In addition, the ribs may have different
shapes, sizes, configurations and arrangements depending, for
example, upon the positioning or the ribs, whether the table
includes a frame and the intended use of the table. For instance,
the ribs may be thicker or more closely spaced to provide
additional strength and/or rigidity, or the ribs may be thinner or
spaced a larger distance apart to provide decreased strength and/or
rigidity. Because the ribs may have different shapes, sizes,
configurations and arrangements, the amount of plastic required to
make the table top may be reduced. In particular, if a portion of
the ribs are spaced apart a greater distance, then that may reduce
the amount of plastic required to mold the table top.
[0013] A further aspect is a table that may include a molded
plastic table top and a layer may be attached to the table top. The
layer, which may also be an insert or cover, may be attached to an
upper surface and/or sides of the table top. The layer may hide
cosmetic defects, provide a visually attractive appearance, be used
for decorative purposes, and the like.
[0014] A still further aspect is a table that may include a molded
plastic table top and a frame that is preferably sized and
configured to help strengthen and/or reinforce the table top. For
example, the frame may include support members, such as rails,
which may be sized and configured to help increase torsional
rigidity of the table top. The support members are preferably
constructed from metal and preferably have a generally tubular
configuration. In addition, the table top and frame preferably
allow the table to be foldable. For instance, the table top and
frame may fold in half to facilitate shipping and/or storage of the
table. The table top and the frame, however, need not be foldable.
Moreover, the frame need not be constructed from tubular support
members or metal, and the frame may have other configurations and
components that are constructed from other materials depending, for
example, upon the intended use of the table.
[0015] Still another further aspect is a table that may include a
table top and a frame with a plurality of support and cross
members. For example, the frame may include two support members
that extend along the length of the table top and two cross members
that are connected to the support members. The table may include
legs that are connected to the cross members and the legs may be
moveable between an extended or use position and a collapsed or
storage position relative to the table top. In particular, the
support members may include openings and the cross members may be
inserted into the openings to allow the legs to pivot relative to
the table top. The openings preferably have a non-circular
configuration and the portions of the cross members inserted into
the openings preferably also have non-circular cross-sectional
configurations. For instance, the openings and the cross member may
have oval, elliptical, oblong or egg-shaped configurations. With
these non-circular configurations, the cross members may be
relatively loosely held within the openings when the legs are in
the collapsed or storage position, but held tightly within the
openings when the legs are in the extended or use position.
[0016] Another aspect is a table that may include a table top with
one or more bosses that are sized and configured to receive at
least a portion of one or more fasteners, such as screws, bolts,
rivets and the like. The bosses may allow various components to be
connected to the table. For example, all or a portion of a frame
may be connected to the table top by fasteners and the bosses. In
greater detail, the bosses preferably extend outwardly from a
portion of the table top, such as a lower portion of the table top.
Advantageously, the bosses may be integrally formed as part of a
one-piece construction during the manufacturing process. For
example, the bosses may be integrally formed with the table top as
part of a unitary, one-piece construction during a molding process,
such as a compression molding process.
[0017] Still another aspect is a table that may include a table
top, a frame and bosses that may be used to position and/or attach
the frame to the table top. For example, the bosses may contact,
abut and/or engage a portion of the frame to position the frame in
the desired location and/or the bosses may attach the frame to the
table top. The table top may also include one or more ribs and the
ribs may be sized and configured to strengthen, reinforce and/or
increase the rigidity of the table top. The ribs may also be used
to help position and/or attach the frame to the table top. For
instance, a portion of the frame may contact, abut and/or engage
the ribs to help position the frame in the desired location and/or
to help attach the frame to the table top. By contacting, abutting
and/or engaging the bosses, ribs or other portions of the table
top, such as a downwardly extending lip, the frame may be quickly
and easily positioned a desired location and/or attached to the
table top.
[0018] Yet another aspect is a table that may include a table top,
frame, fastener bosses and ribs. The bosses may be spaced apart
from the ribs, if desired. This may allow, for example, the frame
to be spaced apart from the ribs, which may help reduce stresses
applied to the ribs.
[0019] A further aspect is a structure that may include a fastener
boss with a body and reinforcing members, such as ribs, that are
sized and configured to reinforce and/or strengthen the body. For
example, the reinforcing members may extend away from the body. In
particular, the reinforcing members may extend away from the body
in a generally tangential direction. By disposing the reinforcing
members in a generally tangential configuration, stresses applied
to the reinforcing members (such as those associated with a
fastener and/or connecting an item to the boss) may be primarily
tensile and compressive forces, in contrast to torsional. This may
advantageously allow the reinforcing members to better bear such
stresses. In addition, the bodies and reinforcing members of the
bosses may have a variety of different shapes and configurations
depending, for example, upon the size and/or intended use of the
structure. For instance, the body may have a generally cylindrical
configuration, but the body may also have a configuration that is
generally square, hexagon, polygonal and the like.
[0020] A still further aspect a structure that may include at a
fastener boss with a body and reinforcing members that extend away
from the body. For instance, the reinforcing members may extend in
a direction that is offset from the center of the fastener boss.
For example, the reinforcing members may be offset from the center
of the boss by about 90 degrees, about 60 degrees, about 45
degrees, about 30 degrees or less. In addition, the reinforcing
members may be disposed within a range relative to the center of
the boss. For example, the reinforcing members may be disposed an
angle between about 80 degrees and about 100 degrees, between about
85 degrees and about 95 degrees, between about 50 degrees and about
70 degrees, between about 55 degrees and about 65 degrees, between
about 35 degrees and about 55 degrees, between about 40 degrees and
about 50 degrees, between about 20 degrees and about 40 degrees
and/or between about 25 degrees and about 35 degrees. The
reinforcing members may also be disposed at larger and/or smaller
angles, and the reinforcing members may extend in other suitable
directions. In will be appreciated, however, that the reinforcing
members do not have to be offset from the center of the boss and
the reinforcing members may be disposed in other angles and
configurations relative to the boss.
[0021] Yet another further aspect a structure that may include a
fastener boss with reinforcing members that extend away from the
body at an oblique angle. The reinforcing members may also be
slanted, sloped or disposed in other suitable angles and
configurations depending, for example, upon the intended use of the
structure. In addition, the same structure may include multiple
types and configurations of bosses. For instance, if the structure
is a table, then the table may include bosses with reinforcing
members disposed at different angles and/or configurations.
[0022] Another aspect is a structure that may be constructed from
molded plastic and include a boss with a body and reinforcing
members that are integrally formed as part of a unitary, one-piece
structure. For example, the structure and bosses may be integrally
formed during a molding process, such as compression molding,
injection molding, blow molding, rotational molding and the like.
All or a portion of the structure may also be constructed from
other materials, such as plastic, metal or wood, using other
suitable processes.
[0023] Advantageously, these structures may be used to form various
items such as table tops, barriers, walls, panels, enclosures,
floors, roofs, chairs, basketball systems and the like. It will be
appreciated that these structures may form all or just a portion of
an item, such as a component or piece of the structure.
[0024] Still another aspect is a fastener boss with a receiving
portion that is sized and configured to allow items to be connected
to the boss. The boss may be integrally formed with a molded
plastic structure and the boss may include reinforcing members. The
reinforcing members may extend outwardly in a radial or non-radial
direction. The reinforcing members may also have other suitable
shapes, sizes, configurations and arrangements depending, for
example, upon the intended use of the molded plastic structure.
[0025] 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
[0039] 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 and/or structures.
[0040] 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 and/or orientations. A
detailed description of the table now follows.
[0041] As shown in FIGS. 1-2, a table 10 may include a table top 12
and legs 14, 16, 18, 20 may be connected to the table top. For
example, the table 10 may include a frame 22 connected to the table
top 12 and the legs 14, 16, 18, 20 may be connected to the frame.
The legs 14, 16, 18, 20 may have an adjustable length, which may
allow the height of the table top 12 to be adjusted. It will be
appreciated, however, that the legs 14, 16, 18, 20 do not require
an adjustable length and that the table 10 may include any suitable
number, shape, size, configuration and arrangement of legs.
[0042] As shown in FIGS. 2-3, the frame 22 may include rails 24, 26
that are connected to the table top 12. One or more cross members
28, 30 may be connected to the rails 24, 26, which may increase
torsional rigidity. The legs 14, 16, 18, 20 may be connected to the
cross members 28, 30 and the cross members may be connected to the
rails 24, 26 to allow the legs to move between an extended or use
position and a collapsed or storage position. In particular, the
rails 24, 26 may include openings that are sized and configured to
receive a portion of the cross member 28, 30 and that may allow the
legs 14, 16, 18, 20 to pivot between the extended or use position
and the collapsed or storage position relative to the table top 12.
If desired, additional cross members 32, 34 may be respectively
connected to the legs 14, 16 and the legs 18, 20 to help add
further strength and/or rigidity to the table 10.
[0043] In some embodiments, the openings in the rails 24, 26 and
the cross members 28, 30 may have non-circular cross-sectional
configurations. With these non-circular configurations, the cross
members 28, 30 may be relatively loosely held within the openings
when the legs 14, 16, 18, 20 are positioned in the collapsed or
storage position, but held tightly within the openings when the
legs are in the extended or use position, for example, as disclosed
in U.S. Pat. No. 7,100,518, which is incorporated by reference in
its entirety. It will be appreciated, however, that the openings
and the cross members 28, 30 do not require non-circular
cross-sectional configurations and that the openings and the cross
members may have any suitable configurations, including circular
cross-sectional configurations if desired. It will also be
appreciated that the table 10 does not require the frame 22 and
that the legs 14, 16, 18, 20 may be connected to the table top 12
using any other suitable structures and components.
[0044] The table top 12 may be formed from plastic using, for
example, a compression molding process. As shown in FIGS. 4-5, the
table top 12 preferably comprises a first table top section 36 and
a second table top section 38, which may be interchangeable. For
example, the table top sections 36, 38 may be compression molded
using the same mold or substantially similar molds, which may allow
the table top sections to be identical or substantially identical
in size, shape and/or configuration. It will be appreciated,
however, that the table top 12 and/or the table top sections 36, 38
may be formed using other suitable processes such as blow-molding,
injection molding and the like. It will also be appreciated that
the table top 12 and/or the table top sections 36, 38 need not be
constructed from plastic and may be constructed from other suitable
materials such as plastic, metal, wood and the like.
[0045] The table top sections 36, 38 may allow the table 10 to be
folded in half, which may provide a compact configuration that
facilitates efficient shipping and/or storage of the table. In
particular, as shown in FIG. 2, the rail 24 may include sections
40, 42 that are connected to the table top sections 36, 38,
respectively, and the rail 26 may include sections 44, 46 that are
connected to the table top sections 36, 38, respectively. With the
rail sections 40, 42 and the rail sections 44, 46 being pivotally
or otherwise movably interconnected, the table 10, the table top
12, the frame 22 and/or the rails 24, 26 may be moved between
unfolded and folded positions. It will be appreciated, however,
that the table 10, the table top 12, the frame 22 and the rails 24,
26 need not be foldable and that the table top 12 and the rails 24,
26 do not require a plurality of sections.
[0046] As shown in FIGS. 5-8, the table top sections 36, 38 may
include one or more engaging or connecting portions that may be
sized and configured to interlock and/or overlap when the table 12
is in an unfolded position, for example, as shown in FIG. 4. In
greater detail, the table top sections 36, 38 may include one or
more projections 48 and one or more receiving portions 50 that are
sized and configured to interlock and/or overlap. Desirably, this
may help strengthen and/or reinforce the table top 12 in the
unfolded position. For instance, the projections 48 may be disposed
proximate a seam formed between the table top sections 36, 38,
which may help reinforce and/or strengthen the table top 12
proximate the seam. The table 10 may also include other suitable
features, such as disclosed in United States Patent Application
Publication No. US 2005/0005826 A1, published Jan. 13, 2005 and
entitled PORTABLE FOLDING TABLE WITH LOCKING HINGE, which is
incorporated by reference in its entirety.
[0047] As shown in FIGS. 4 and 5, the table top 12 may include
fastener bosses 52 that are sized and configured to receive at
least a portion of a fastener, such as a screw, bolt, rivet and the
like. Advantageously, the fastener bosses 52 may be sized and
configured to allow various items to be connected to the table top
12, such as the frame 22. For example, the rails 24, 26 of the
frame 22 may include openings 54, as best shown in FIGS. 2 and 3,
and the fasteners 56 may be inserted through the openings and
received by the fastener bosses 52 to connect the rails 24, 26 to
the table top 12.
[0048] In further detail, as shown in FIGS. 9-10, the fastener
bosses 52 may include a body 58. The body 58 preferably has a
generally cylindrical shaped configuration; however, the body may
have a square, hexagon, polygonal and/or other suitable shapes,
sizes, configurations and arrangements depending, for example, upon
the intended use of the boss 52. In greater detail, the body 58 may
be disposed in or extend outwardly from a surface or portion of the
table top 12, such as the underneath portion of the table top. The
bosses 52 may be used to connect the frame 22 to the table top 12.
Advantageously, the bosses 52 may be used to position the frame 22
in the desired positions and locations. For example, the bosses 52
may be used to space the frame 22 away from the lower surface
and/or outer edges of the table top 12. For example, the body 58 of
the boss 52 may have a height that is sized and configured to space
the frame 22, such as the rails 24, 26, a desired distance from the
lower surface or portion of the table top 12. In addition, the
bosses 52 may be positioned so that the frame 22 is disposed in a
desired location. For instance, if the frame 22 is desired to be
spaced apart from an outer edge or perimeter, then the bosses 52
may be spaced apart from the outer edge of perimeter of the table
top 12. On the other hand, if the frame 22 is desired to be
positioned at least proximate the outer edge or perimeter of the
table top 12, then the bosses may be positioned at least proximate
the outer edge or perimeter of the table top. Thus, the bosses 52
may be positioned in various suitable positions and locations.
[0049] The body 58 of the boss 52 may include a receiving portion
60 that is sized and configured to receive and/or retain at least a
portion of a fastener 56. For example, the fastener 56 may include
a threaded portion that is sized and configured to bite into or
otherwise engage at least a part of the receiving portion 60 to
receive and retain at least a portion of the fastener within the
receiving portion. For instance, the fastener 56 may be a screw
that may be screwed into the receiving portion 60 and the threaded
portion of the screw may bite into and engage a surface 62 to help
connect the fastener to the boss. It will be appreciated, however,
that the fasteners 56 may be connected to the bosses 52 in any
desired configurations or arrangements depending, for example, upon
the intended use of the table 10.
[0050] As shown in FIG. 9, the fastener bosses 52 may include one
or more reinforcing members 64, 66, which may be sized and
configured to strengthen, reinforce and/or more securely connect
the bosses to a structure. For example, the reinforcing members 64,
66 may be sized and configured to strengthen and/or reinforce the
body 58 to help the body withstand stresses as fasteners 56 are
connected and/or disconnected. This may help avoid damaging the
fastener bosses 52 and/or other portions of the table top 12 when
connecting the rails 24, 26 to the table top 12. In addition, the
reinforcing members 64, 66 may help prevent the bosses 52 from
undesirably twisting, distorting or otherwise deforming when forces
are applied to the bosses. The reinforcing members 64, 66 may also
more securely attach the bosses 52 to the table top 12, which may
allow a strong table 10 to be constructed or allow components to be
more securely connected to the table top 12. Further, because the
bosses 52 may be more securely connected to the table top 12, that
may help prevent the table top from being damaged when forces are
applied to the table 10.
[0051] The reinforcing members 64, 66 are preferably connected to
the body 58 to help the boss 52 withstand such stresses. For
example, the reinforcing members 64, 66 may be integrally formed
with the body 58 as part of a unitary, one-piece structure. In
particular, the fastener bosses 52 may be formed from molded
plastic and the body 58 and the reinforcing members 64, 66 may be
integrally formed as part of a unitary, one-piece structure during
the molding process. Advantageously, this may allow the bosses 52
to be integrally formed as part of a unitary, one-piece table top
12 or table top section 36, 38 during a molding process, such as
compression molding, injection molding, blow-molding process and
the like. The bosses 52, however, do not have to be integrally
formed and the bosses do not have to be integrally formed with the
table top 12 or the table top sections 36, 38. In addition, the
bosses 52 need not be formed from plastic and may be constructed
from other suitable materials and with various manufacturing
processes.
[0052] Advantageously, the bosses 52 may have a variety of suitable
shapes, sizes, configurations and arrangements depending, for
example, upon the intended use of the table 10. For example, the
reinforcing members 64, 66 may extend away from the body 58 of the
boss 52, which increase the strength of the boss. In particular,
the outwardly extending reinforcing members 64, 66 may extend in a
non-radial direction away from the body 58. For example, as shown
in FIG. 6, the reinforcing members 64, 66 may extend in a generally
tangential direction away from the body 58. Significantly, when the
reinforcing members 64, 66 extend in a generally tangential or
other non-radial direction away from the body 58, the reinforcing
members may allow the bosses 52 to withstand larger forces or
stresses, such as when fasteners 56 are screwed into the receiving
portions 60 of the fastener bosses. In particular, by configuring
the reinforcing members 64, 66 to extend in a generally tangential
direction, stresses applied to the reinforcing members may be
applied along a greater portion of the length (as opposed to the
thickness) of the reinforcing members. Thus, these forces may be
primarily tensile and compressive, in contrast to torsional, which
may allow the reinforcing members 64, 66 to better withstand such
stresses and may help avoid damaging the bosses 52 and/or other
portions of the table top 12. This may also allow thinner or
otherwise smaller reinforcing members 64, 66 to be used, which may
help reduce the amount of materials required to construct the table
top 12.
[0053] The reinforcing members 64, 66 may also extend away from the
body 58 of the bosses 52 in a direction that is offset from the
center of the boss. For example, the reinforcing members 64, 66 may
be generally aligned with an outer edge or perimeter of the boss.
The reinforcing members 64, 66 may also be offset from the body 58
of the boss 52 by an angle, such as about 90 degrees, about 60
degrees, about 45 degrees, about 30 degrees or less. The
reinforcing members 64, 66 may also be disposed within a range,
such as between about 80 degrees and about 100 degrees, between
about 85 degrees and about 95 degrees, between about 50 degrees and
about 70 degrees, between about 55-degrees and about 65 degrees,
between about 35 degrees and about 55 degrees, between about 40
degrees and about 50 degrees, between about 20 degrees and about 40
degrees and/or between about 25 degrees and about 35 degrees. If
desired, the reinforcing members 64, 66 may be disposed in at other
angles and/or offset from the center of the fastener boss 52 at
greater or lesser angles. In addition, the reinforcing members 64,
66 may extend outwardly at an oblique or other suitable angle.
[0054] As shown in FIG. 9, the reinforcing members 64, 66 may
comprise ribs, flanges, outwardly extending projections and the
like, and the reinforcing members preferably have a generally
uniform thickness. In addition, the reinforcing members 64, 66 may
have an elongated shape that includes a first end connected to the
body 58 and a second end that is spaced apart from the body. For
example, the reinforcing members 64, 66 may be connected to a
substantial portion of the body 58, such as at least one-third, at
least one-half, at least two-thirds or more of the height of the
body, as shown in FIG. 9. The second end of the reinforcing members
64 may be disposed at various angles relative to the body 58 of the
boss 52 and/or the lower surface or portion of the table top 12.
For example, the second end of the reinforcing members 64 may be
disposed at about ninety degrees relative to a lower surface or
portion of the table top 12. The second end of the reinforcing
members 66 may be disposed at an oblique angle (for instance,
between about thirty and sixty degrees or between about forty and
fifty degrees) relative to the lower surface or portion of the
table top. It will be appreciated, however, that the reinforcing
members 64, 66 do not require a generally uniform thickness or an
elongated shape. It will also be appreciated that the reinforcing
members 64, 66 may have other suitable sizes, shapes and/or
configurations. Additionally, it will be appreciated that the table
10 may include any suitable number of reinforcing members 64, 66
and/or bosses 52, but neither the reinforcing members nor bosses
are required.
[0055] As mentioned above, the fastener bosses 52, the body 58 and
the reinforcing members 64, 66 may be integrally formed as part of
a unitary, one-piece structure during a molding process.
Advantageously, the bosses 52 can be used in connection with a wide
variety of structures and components, such as tables 10, table
sections, sheds (including roof panels, wall panels, floor panels,
door panels, gables, shelves or skylights), basketball systems
(including backboards or bases), fences, barriers, panels, chairs
(including chair seats, backrests or armrests), toys and the like.
The fastener bosses 52, bodies 58 and/or reinforcing members 64,
66, however, need not be integrally formed as part of a unitary,
one-piece structure and may be constructed from other suitable
materials using various manufacturing processes. Significantly,
this may allow the fastener bosses 52, the body 58 and/or the
reinforcing members 64, 66 to be used in even more structures
and/or contexts.
[0056] The table top 12 may include one or more ribs, which may be
sized and configured to strengthen and/or reinforce the table top
12. In particular, as shown in FIGS. 7-8, a table top section 36,
38 of the table top 12 may include ribs 68. The ribs 68 may be
arranged in a pattern that may include a first set of one or more
ribs 68 extending along the table top section's length and a second
set of one or more ribs extending along the table top section's
width.
[0057] As shown in FIG. 7, the first and second sets of ribs may be
generally perpendicular to each other and may form a pattern of
generally rectangular shapes (such as generally rectangular shapes
70, 72). The generally rectangular shapes 72 may be at least about
one, two or three times the size of the generally rectangular
shapes 70, for instance, at least about 1.5 times the size of the
generally rectangular shapes 70. It will be appreciated, however,
the rectangles 70, 72 may have other suitable sizes and may be same
size, if desired. It will be further appreciated that the pattern
of ribs 68 may include, for example, a generally uniform pattern of
squares or other suitable patterns of rectangles, triangles,
polygons and/or other shapes, if desired
[0058] The pattern of ribs 68 may be sized and configured to help
provide different strength and/or reinforcement for different
portions of the table top section 36, 38. In particular, the
pattern of ribs 68 may be sized and configured to provide more
strength and/or reinforcement in places spaced apart from the frame
22 than in places proximate the frame. For example, as shown in
FIGS. 2 and 7, the pattern of ribs may be denser proximate a
generally central portion of the table top section 36, 38 that is
spaced apart from the rails 24, 26, but less dense proximate the
rails. The denser portions of the pattern may provide additional
strength and/or reinforcement in locations that benefit less from
the strength and/or reinforcement provided by the rails 24, 26.
Significantly, this may help the table 10 provide a working surface
with a generally consistent strength. Moreover, the less dense
portions of the pattern may require less plastic, which may help
reduce the overall manufacturing costs for the table 10. It will be
appreciated, however, that the pattern of ribs 68 does not require
denser portions.
[0059] The table top section 36, 38 preferably includes pattern of
ribs including a first set of one or more ribs 68 that may extend
along all or at least a substantial portion of the table top
section's length and a second set of one or more ribs that may
extend along all or at least a substantial portion of the table top
section's width. For instance, as shown in FIG. 8, the table top
section 36, 38 may include an outer edge or lip 74 and one or more
of the ribs 68 may extend between and/or be connected to one or
more portions of the outer edge or lip. It will be appreciated,
however, that the table top section 36, 38 does not require any
outer edge or lip 74.
[0060] As shown in FIGS. 2 and 8, the ribs 68 may be connected to
the lip 74 and/or a lower portion or surface of the table top 12.
For example, to connect the ribs 68 to the lip 74 and the lower
portion or surface of the table top 12, the ribs, the lip and the
lower portion or surface may be formed from molded plastic and may
be integrally formed as part of a unitary, one-piece structure
during the molding process, which may be a compression molding
process, an injection molding process, a blow-molding process
and/or other molding process. The ribs 68, of course, may be
connected to other portions of the table top 12 and/or table 10, if
desired. In addition, the ribs 68, the lip 74 and the lower portion
or surface of the table top need not be formed from plastic and may
be constructed from other materials using other suitable
manufacturing processes.
[0061] As shown in FIG. 7, the fastener bosses 52 may be spaced
apart from the ribs 68 and may be located within one or more
generally rectangular shapes formed by the ribs. The fastener
bosses 52, however, may contact, abut, engage and/or be connected
to the ribs 68, if desired.
[0062] As shown in FIGS. 4 and 8, the ribs 68 of the table top
sections 36, 38 may include one or more raised portions 76 sized
and configured to be aligned with each other when the table 10 and
the table top 12 are in the folded position. In particular, one or
more of the raised portions 76 of the table top section 36 may be
sized and configured to contact, abut and/or engage the raised
portions 76 of the table top section 38 when the table 10 and the
table top 12 are in the folded position. Significantly, if the
raised portions 76 of the table top sections 36, 38 contact, abut
and/or engage each other, this may help add strength and/or
stability to the folded table 10 and table top 12. Moreover, if the
raised portions 76 of the table top sections 36, 38 contact, abut
and/or engage each other, this may help prevent the rail sections
40, 42, 44, 46 and/or other portions of the table 10 from
contacting each other, which could scratch or otherwise damage
them.
[0063] The raised portions 76 may also facilitate storage of a
plurality of table top sections 36, 38 for later assembly as part
of a table 10. For instance, the table top sections may be stacked
on top of each other with the raised portions 76 generally aligned.
Desirably, this may help reinforce and/or strengthen the stack,
which may include two, three, four or more table top sections, if
desired. Any number or combination of adjacent table top sections
may face the same direction or opposing directions in the stack, if
desired.
[0064] As shown in FIG. 2, one or more portions of the frame 22
(for instance, one or more portions of the rails 24, 26) may
contact, abut and/or engage the fastener bosses 52. In addition,
one or more portions of the frame 22 may contact, abut and/or
engage the ribs 68. By contacting, abutting and/or engaging the
fastener bosses 52 and/or the ribs 68, the frame 22 may be more
quickly easily positioned a desired location, such as a particular
distance apart from a lower surface of the table top. It will be
appreciated, however, that the frame 22 need not contact, abut
and/or engage the fastener bosses 52 or the ribs 68 depending, for
example, upon the particular configuration of the table 10. It will
also be appreciated that the frame 22 need not be spaced apart from
a lower surface of the table top and that the frame may be
positioned in other suitable locations.
[0065] In some instances, by contacting, abutting and/or engaging
the fastener bosses 52, the frame 22 may be secured to the table
top 12 in a position that is spaced apart from the ribs 68, which
may help reduce stresses applied to the ribs. It will be
appreciated, however, that the frame 22 need not be spaced apart
from the ribs and that the frame may be positioned in other
suitable locations. It will also be appreciated that the table top
does not require any ribs 68 or fastener bosses 52.
[0066] As shown in FIGS. 2 and 10-12, the table 10 may include a
retainer 78 that may be sized and configured to secure the table in
the folded position. For example, as shown in the accompanying
figures, the retainer 78 may be connected to a first portion of the
table 10, such as the table top section 36. In particular, the
retainer 78 may be connected to the cross member 28. The retainer
78 is preferably sized and configured to be connected to a second
portion of the table 10, such as the table top section 38, when the
table is in the folded position. In greater detail, the retainer 78
is preferably sized and configured to be connected to the cross
member 30, when the table top 12 is in the folded position.
[0067] Advantageously, the retainer 78 may retain the table 10 in
the folded position so that the table does not unintentionally
unfold when the folded table is being carried, transported and/or
stored. In addition, the retainer 78 may be sized and configured to
automatically engage the other portion of the table to simplify the
engagement process. The retainer 78 may also be quickly and easily
connected to the cross members 28, 30, which may simplify the
manufacturing process and allow the retainer to be used in a wide
variety of situations and environments. Additionally, the retainer
78 may be connected to suitable portions of the table top 12 to
secure the retainer in a fixed position. Significantly, because the
retainer 78 may be connected to the table top 12 and/or the cross
members 28, 30 by a snap, friction or interference fit, the
retainer may be easy to use and mechanical fasteners may not be
required. It will be appreciated, however, that the retainer 78 may
be connected to the table 10 by mechanical fasteners, adhesives,
and the like and that the retainer can be attached to any suitable
portions of the table.
[0068] Desirably, one portion of the retainer 78 is securely
connected to a first portion of the table 10, such as the cross
member 28, so that the retainer is permanently connected or not
easily removed from the first portion. Another portion of the
retainer 78 is preferably selectively connected to the second
portion of the table top 12, such as the cross member 30, so that
the retainer may be quickly and easily attached and detached. This
may allow the retainer 78 to quickly and easily secure the table 10
and table top 12 in the folded position, and allow the table and
table top to be quickly and easily moved into the unfolded
position. It will be appreciated that either or both portions of
the retainer 78 may be selectively or permanently connected to
suitable portions of the table 10 and/or the table top 12
depending, for example, upon the design and/or intended use of the
table.
[0069] As shown in FIG. 11, the retainer 78 may include a body 80
including a first clip 82 that is sized and configured to be
connected to the cross member 28 and a second clip 84 that is sized
and configured to be connected to the cross member 30. As shown in
FIG. 10, the cross member 28 is preferably disposed within the clip
82. The cross member 30 is preferably disposed within the clip 84
when the folding table 10 is in the folded position. As shown in
the accompanying figures, the cross members 30, 28 may have a
generally circular cross sectional configuration, but the cross
members could have other suitable configurations.
[0070] In further detail, the clip 82 may include one or more
resiliently deformable arms that project from the body 80. The arms
preferably include free ends that are separated by an opening or
gap. As the cross member 28 is inserted into the gap, the free ends
of the arms may deflect outwardly to allow the cross member to be
inserted into the clip 82. The arms may then resiliently return to
their original configuration to receive and retain the cross member
28 within the clip 82. It will be appreciated that the cross member
28 may be connected to the clip 82 using other suitable types of
connections.
[0071] When the table top 12 is moved into the folded position, the
cross member 30 is preferably received and retained in the clip 84
by a snap fit, a friction fit, an interference fit or the like. For
example, the clip 84 may include resiliently deformable arms that
project from the body 80. The arms preferably include free ends
that are separated by an opening or gap. As the cross member 30 is
inserted into the gap, the free ends of the arms may deflect
outwardly to allow the cross member to be inserted into the clip
84. The arms may then resiliently return to their original
configuration to receive and retain the cross member 30 within the
clip 84. It will be appreciated that the cross member 30 may be
connected to the clip 84 using other suitable types of
connections.
[0072] As mentioned above, the arms of the clip 82 preferably
include free ends that are separated by a gap or opening that are
sized and configured to receive and retain the cross member 28. The
arms of the clip 84 also preferably include free ends that are
separated by a gap or opening that are sized and configured to
receive and retain the connection rod 30. Preferably, the cross
member 28 is more securely attached to the retainer 78 than the
cross member 30 so that when the table top 12 is moved to the
unfolded position, the cross member 30 is released from the clip
84. It will be appreciated, however, that the cross members 30, 28
may be selectively and/or securely attached to the clips 82, 84, as
desired.
[0073] As best seen in FIG. 11, the opening between the arms of the
clip 82 is preferably offset from the opening between the arms of
the clip 84. In this offset configuration, at least one of the arms
of the clip 82 may be sized and configured to help secure the
retainer 78 in a generally fixed relationship relative to the table
top 12 and/or secure the cross member 28 within the clip 82 when
the table top 12 is moved between the folded and unfolded
positions. Thus, when the table top 12 is moved from the folded
position to the unfolded position, the cross member 30 is
preferably removed from the clip 84 and at least one arm of the
clip 82 may help resist movement of the retainer 78, for example,
by engaging at least a portion of the table (such as the cross
member 28). Thus, the arm of the clip 82 helps to help secure the
retainer 78 in a generally fixed relationship relative to the table
top 12 and/or the cross member 28.
[0074] As shown in FIGS. 10-12, the table top 12 may include one or
more positioning members sized and configured to secure the
retainer 78 in a generally fixed position relative to the table top
12. For example, the table top 12 may include a first positioning
member (such as a rib 68) that may that contact, abut, engage
and/or be disposed at least proximate to a lower portion of the
retainer, which may help prevent the retainer 78 from undesirably
rotating relative to the cross member 28. In addition, the table
top 12 may include second and third positioning members (such as
ribs 86) that contact, abut, engage and/or are disposed at least
proximate to opposing sides of the retainer 78, which may help
prevent the retainer 78 from undesirably sliding along the length
of the cross member 28. The positioning members may be connected to
a lower portion or surface of the table top 12. For example, the
positioning members and the lower portion or surface may be formed
from molded plastic and may be integrally formed as part of a
unitary, one-piece structure during the molding process, which may
be a compression molding process, an injection molding process, a
blow-molding process and/or other molding process. The positioning
members, of course, may be connected to other portions of the table
top 12 and/or table 10, if desired. In addition, the positioning
members and the lower portion or surface of the table top need not
be formed from plastic and may be constructed from other materials
using other suitable manufacturing processes. It will be
appreciated that the positioning members need not include ribs and
may include other structures having other suitable features.
[0075] As shown in FIGS. 7 and 8, the table top 12 and/or a table
top section 36, 38 may include a corner reinforcing structure 88.
The corner reinforcing structure 88 may include a first rib 90 and
a second rib 92. The rib 90 may include a first end connected to a
first portion of the outer lip or edge 74 and a second end
connected to a second portion of the outer lip or edge. The rib 92
may include a first end connected to the rib 90 and a second end
connected to a third portion of the outer lip or edge 74, which may
be positioned between the first and second portions of the outer
lip or edge to which the rib 90 is connected. Desirably, the
reinforcing structure 88 and/or the ribs 90, 92 may be integrally
formed in the table top as part of a unitary, one-piece structure
during, for example, a molding process.
[0076] As mentioned above, the table top 12 and/or a table top
section 36, 38 may be formed from molded plastic. In some
embodiments, an insert or cover may be placed into a mold, a charge
of moldable plastic may be placed onto the insert or cover, and
then the insert and the moldable plastic may be molded into the
table top and/or table top section using, for example, a
compression molding process or other molding process.
Significantly, the insert may help hide cosmetic defects and/or may
provide a visually attractive appearance. The insert is preferably
positioned in the mold such that it may form part of an upper
working surface of the molded table top and/or table top section
and may be sized and configured to form all or at least a
substantial portion of the upper working surface. The insert
preferably comprises a graphical insert that may include a sheet
with one or more graphics printed thereon. The sheet may have a
porous configuration which may help prevent the sheet from forming
air bubbles. One such exemplary sheet may be a Teslin.RTM. sheet
(commercially available from PPG Industries, One PPG Place,
Pittsburgh, Pa. 15272, United States of America), but other sheets
and/or other inserts may be used. It will be appreciated that the
insert may have other sizes and may be positioned in other
locations to form other portions of the molded table top and/or
table top section. It will also be appreciated that the table top
12 and the table top sections 36, 38 do not require any graphical
inserts or any other inserts.
[0077] If desired, one or more graphics may be screen printed onto
the upper working surface and/or other surfaces of the table top 12
and the table top sections 36, 38. This may also help hide cosmetic
defects and/or may provide a visually attractive appearance. It
will be appreciated, however, that this printing is not
required.
[0078] Significantly, one or more of components of the table 10 may
be constructed from a relative strong material, such as metal. For
example, the legs 14, 16, 18, 20; the frame 22; the rails 24, 26;
the cross members 28, 30, 32, 34; and/or the rail sections 40, 42,
44, 46 may be constructed from metal tubes, which may
advantageously be strong, yet relatively lightweight. It will be
appreciated, however, that these components do not require tubular
configurations and may have other shapes and/or configurations. It
will also be appreciated that these components need not be
constructed from metal and may be constructed from other suitable
materials, if desired.
[0079] As discussed above, components of the table 10 may be
constructed from plastic. Exemplary molding systems and methods
that may be used to constructed these plastic components are
disclosed in U.S. patent application Ser. No. 11/771,378, which was
filed Jun. 29, 2007, entitled MOLDING SYSTEMS AND METHODS; U.S.
provisional patent application Ser. No. 60/817,834, which was filed
Jun. 29, 2006, entitled MOLDING SYSTEMS AND METHODS; and U.S.
provisional patent application Ser. No. 60/847,548, which was filed
Sep. 27, 2006, entitled TABLE WITH MOLDED TABLE TOP. Each of these
applications are incorporated by reference in their entireties. It
will be appreciated, however, that other molding systems and
methods that may be used to constructed these plastic
components.
[0080] 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.
