BACKGROUND OF THE INVENTION
[0002] 1. The Field of the Invention
[0003] The present invention is related to a utility table, and
more particularly, to a portable folding utility table having one
or more center support assemblies and off-set support legs that
selectively support the utility table above a surface.
[0004] 2. The Technical Background
[0005] Portable folding utility tables are indispensable for groups
or organizations that have limited floor space usable for multiple
purposes. For example, foldable utility tables can be placed in a
pre-determined configuration to meet the space requirements of a
school gymnasium, a church multi-purpose room, or a hotel
conference meeting room. Afterward, the tables can be neatly stored
away and the conference or meeting room used for a different
purpose. Thus, portable folding utility tables allow a group or
organization to maximize the efficiency and utility of a particular
space.
[0006] Foldable utility tables can also provide an immediate
temporary work space in a garage, tool shed, and the like. The
portability and foldability of these utility tables allows a user
to conveniently set up, take down, and store the table whenever and
wherever the user chooses.
[0007] A major drawback with many portable folding utility tables
of the prior art, however, is their inherent size and bulkiness.
Many such utility tables require two people to collapse and store
the table after use. Moreover, some prior art portable folding
utility tables are heavy enough to cause injury if dropped or
mishandled. These unwieldy tables are usually made from hardwood,
particle board, or similarly heavy materials. In an attempt to
overcome this weight and bulkiness problem, some prior art portable
utility tables are formed of lighter-weight materials. However,
many of these lightweight utility tables generally lack the
sturdiness of the heavier-weight prior art utility tables.
[0008] Another disadvantage to prior art utility tables is the
means used for attaching the table support legs or two or more
support pedestals to the underside of the table. As will be
appreciated, prior art table support legs are typically attached to
the table top using threaded screws or bolts that are drilled into
the underside of the table top. This means of attachment may
compromise the integrity of the table top thereby making it weaker
at the point of attachment between the table support legs and the
table top. Other attachment mechanisms may include a form of
bonding the table support legs as support pedestals directly
against the surface of the table top. Often, however, this means of
attachment by bonding weakens the structural integrity of the table
top. Thus, when the table support legs fail, a portion of the
material forming the table top may pull away at the point of the
bonded attachment thereby making the table costly, if not
impossible to repair.
[0009] In an attempt to overcome the foregoing disadvantages, prior
art utility tables were developed by those skilled in the art that
are equipped with complex or heavy-duty attachment mechanisms that
facilitate a secure attachment between the table support legs or
the support pedestals and the table top. These types of attachment
mechanisms, however, are normally heavier, more costly, more
difficult to install, and typically require additional time to
manufacture.
[0010] The previously stated disadvantages are compounded by the
fact that many prior art utility tables incorporate a separate and
distinct attachment mechanism for attaching each table support leg
or pedestal to the table top. As appreciated, most existing
portable folding utility tables have two sets of support legs or
pedestal supports, one at each end of the table. Each of these
supports is typically attached to the underside of the table top at
two places or points of contact. Correspondingly, many of these
types of utility tables have at least four separate points of
attachment, each attachment between the support legs or pedestal
supports facilitated by a separate attachment mechanism. One
particular problem with utility tables having separate and distinct
attachment mechanisms is that they are generally susceptible to
bowing in the center of the table top under stress. This is
especially true with larger banquet style tables.
[0011] Yet another drawback with many prior art utility tables is
that the hard materials used to maintain a sufficient rigidity and
sturdiness of the table top often have sharp edges which may be
uncomfortable for the user to lean against or rest their arms upon.
Further, these materials may also be susceptible to damage or
degradation from the elements of nature.
[0012] In addition, smaller utility tables that are found in the
prior art usually comprise shortened support legs that fail to
provide sufficient height to the table top in relation to the
underlying surface, thus these types of table are generally
uncomfortable to users. In particular, when these prior art utility
tables are configured in the folded position for storage, the table
support legs are required to be short enough so not to interfere
with each other when folded in a conventional fashion underneath
the table top. Small folding utility tables of the prior art are
also typically bulky when disposed in the folded position because
complex and unwieldy mechanisms are generally required to
accommodate the use of longer support legs that may be incorporated
to overcome the inherent height deficit found in most smaller
utility tables.
[0013] From the foregoing, it will be appreciated that it would be
an advancement in the art to provide a portable folding utility
table that is durable enough to withstand the increased wear and
tear that portable utility tables are subjected to over long
periods of time and sturdy enough to support varying sized loads
that will be placed on the table, while at the same time being
light-weight enough to be easily set up and taken down.
[0014] It would be another advancement in the art to provide a
portable folding utility table having a leg or support pedestal
attachment mechanism that does not involve a complex design, heavy
duty attachment hardware, or need to be screwed, bolted, or bonded
to the under side of the table top. It would be a further
advancement in the art to provide a portable folding utility table
that minimizes the points of attachment to the surface of the table
top and facilitates attachment mechanisms that interrelate with
each other to support the table top above an underlying
surface.
[0015] Furthermore, it would be an advancement in the art to
provide a portable folding utility table that may provide a smaller
working surface than larger utility table, but that is comfortable
to work at in relation to its height disposition and which is
capable of withstanding the elements of nature.
[0016] Finally, it would be an advancement in the art to provide a
portable folding utility table in which the support legs or
pedestals, having a length greater than the corresponding length of
the table top, can fold against the underside of the table top when
disposed for storage without interfering with each other, so that
smaller frames and table tops can be used that accommodate a
sufficient height disposition in relation to the underlying support
surface.
[0017] Such a portable folding utility table is disclosed and
claimed herein.
BRIEF SUMMARY OF THE INVENTION
[0018] The present invention is directed to a novel portable
folding utility table having a center support assembly. The utility
table includes a table top supported by a pair of support
pedestals. In one presently preferred embodiment, the table top
includes a mounting surface and a working surface formed opposite
the mounting surface. The working surface may be textured and may
include an outer periphery, at least a portion of which is beveled
to provide comfort to a user.
[0019] A first end of each support pedestal is preferably attached
to the mounting surface of the table top. In one presently
preferred embodiment, the support pedestals are pivotally attached
to the mounting surface of the table top, to allow each support
pedestal to be moved between a collapsed position and an extended
position for supporting the table top above a surface. A securing
member may also be attached to the mounting surface for releasably
securing one or more support pedestals in the collapsed
position.
[0020] Additionally, the utility table may include a first pivoting
support brace attached to the first support pedestal at a proximal
end and to the mounting surface at a distal end thereof. Similarly,
a second pivoting support brace may be attached to the second
support pedestal at a proximal end and to the mounting surface at a
distal end thereof. In one presently preferred embodiment of the
present invention, the distal ends of the first and second pivotal
support braces are disposed contiguous to each other at a retention
assembly attached to the mounting surface or, in the alternative,
to a support frame.
[0021] In one presently preferred embodiment of the present
invention, the retention assembly may include a single cross-brace
member disposed through openings formed at the distal ends of the
pivotal support braces and secured to the mounting surface. The
mounting surface may be configured such that opposing ends of the
cross-brace member are introduced through openings disposed in
opposing sides of the mounting surface of the table top and may
further include a mount for receiving and retaining the cross-brace
member therein. Thus, the distal ends of both support pedestals are
preferably attached along the length of the cross-brace member
which is secured to the mounting surface, thereby reducing the
number of attachment mechanisms and interrelating the support
pedestals to the table top to increase structural support and
efficiency of manufacture.
[0022] In another presently preferred embodiment, each support
pedestal includes a first member pivotally engaging the mounting
surface of the table top and a second member configured for
telescoping engagement with the first member. This configuration
permits the height of the support pedestal to be disposed between a
lengthened position and a retracted position.
[0023] In an alternative presently preferred embodiment, the table
may include two cross-brace members providing separate attachment
points for the first and second pivotal support braces. Such a
configuration is particularly desirable for tables having an
extended length, in which it may not be advantageous for each of
the pivotal support braces to have lengths sufficient for extending
into the center of the table top. Correspondingly, a dual
cross-brace configuration may provide additional space for
accommodating one or more user's legs under the table top.
[0024] Moreover, in yet another presently preferred embodiment of
the present invention, each support pedestal may include two legs
slightly offset from the corresponding legs of the other support
pedestal disposed on the opposing side of the table top, so that
longer support legs can be accommodated under a smaller table top
when disposed above an underlying surface. This off-set distance is
sufficient to keep the support legs of the opposing support
pedestal from interfering with one another, thus allowing
displacement substantially against the mounting surface of the
table top when disposed in the retracted position for storage.
[0025] From the foregoing, it will be appreciated that the present
invention provides a portable folding utility table that is durable
enough to withstand increased wear and tear yet is light-weight for
easy set up and take down. The present invention also provides a
novel center support assembly that provides increased structural
stability to the table top with efficient design such that to allow
the interrelation of the support pedestals. The center support
assembly is also cost effective to manufacture and does not
compromise the structural integrity of the table top. Further, the
present invention provides a utility table that facilitates a
height that is comfortable for one or more users to work at. The
foregoing and other advantages and features of the present
invention will become more fully apparent by examination of the
following description of the presently preferred embodiments and
appended claims, taken in conjunction with the accompanying
drawings.
[0026] These and other objects and features of the present

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] It will be readily understood that the components of the
present invention, as generally described and illustrated in the
Figures herein, could be arranged and designed in a wide variety of
different configurations Thus, the following more detailed
description of the embodiments of the assembly and method of the
present invention, as represented in FIGS. 1 through 5, is not
intended to limit the scope of the invention, as claimed, but it is
merely representative of the presently preferred embodiments of the
invention.
[0034] The presently preferred embodiments of the invention will be
best understood by reference to the drawings, wherein like parts
are designated by like numerals throughout.
[0035] One presently preferred embodiment of the present invention,
designated generally at 10, is best illustrated in FIGS. 1 and 2.
As shown, with particular reference to FIG. 1, a utility table
according to the present invention is generally designated at 10.
The utility table 10 preferably includes a table top 12 having a
mounting surface 14 and a working surface 16 disposed opposite the
mounting surface 14. In one presently preferred embodiment, the
table top 12 is supported by a first support pedestal 18 and a
second support pedestal 20. The first and second support pedestals
18, 20 may each comprise a first end 22 attached to the mounting
surface 14 of the table top 12.
[0036] Referring now to FIGS. 1 and 2, the utility table 10 of one
presently preferred embodiment includes a first pivotal support
brace 24 having a proximal end 26 attached to the first support
pedestal 18 and a distal end 28 attached to the mounting surface
14. Similarly, a second pivotal support brace 30 is shown having a
proximal end 32 attached to the second support pedestal 20 and a
distal end 34 attached to the mounting surface 14. The distal end
28 of the first pivotal support brace 24 may be disposed contiguous
the distal end 34 of the second pivotal support brace 30. The
distal ends 28, 34 of the pivotal support braces 24, 30 are
disposed in relation to a retaining assembly 36, which may be
attached to the mounting surface 14. In one preferred embodiment,
the retaining assembly 36 comprises a cross member.
[0037] As shown in FIG. 2, the utility table 10 includes a frame
40. The frame 40 may comprise a first side rail 42 and an opposing
second side rail 44. Preferably, the first side rail 42 is disposed
substantially parallel the opposing second side rail 44, thereby
providing a generally longitudinal alignment therebetween. The
first and second side rails 42, 44 may be configured with a
plurality of retaining apertures 46 to facilitate attachment of the
support pedestals 18, 20 and the cross brace member 36 to the frame
40.
[0038] In one presently preferred embodiment, the mounting surface
14 of the table top 12 comprises opposing longitudinal interior
side walls 48 and opposing orthogonal interior side walls 52
disposed along an interior periphery of the table top 12. The first
and second side rails 42, 44 may be secured to respective opposing
longitudinal side walls 48, thus adding rigidity and strength to
the structural integrity of table top 12. In one presently
preferred embodiment, the side rails 42, 44 are secured to the
opposing longitudinal side walls 48 by fasteners. It will be
appreciated by those skilled in the art that the side rails 42, 44
may be secured to the opposing longitudinal side walls 48 of the
mounting surface 14 using any number or variety of fasteners
readily known in the art, such as, for example, screws, bolts,
rivets, adhesives, or the like.
[0039] The cross-section of the side rails 42, 44 may be configured
having an S-shape. In one presently preferred embodiment, the side
rails 42, 44 may be attached to the respective longitudinal side
walls 48, 50 as to form respective channels 50 along the side rails
42, 44 between the side rails 42, 44 and the longitudinal side
walls 48 (See FIGS. 1 and 2). In this configuration, the first end
22 of the support pedestals 18, 20 may be positioned within
opposing respective retaining apertures 46 formed in the side rails
42, 44 abutting the longitudinal side walls 48 within the channels
50, thereby substantially preventing lateral movement of the
support pedestals 18, 20 relative to the table top 12. Likewise,
the cross brace member 36 may be positioned within opposing
respective retaining apertures 46 formed in the side rails 42, 44
abutting the longitudinal side walls 48 within the channels 50,
thereby substantially preventing lateral movement of the cross
brace member 36 relative to the table top 12. In one presently
preferred embodiment, the support pedestals 18, 20 and the cross
brace member 36 are preferably disposed substantially parallel to
each other and in spaced-apart relationship, wherein the cross
brace member 36 is positioned between the opposing support
pedestals 18, 20. Still referring to FIG. 2, the frame 40 may also
comprise a first end rail 54 and an opposing second end rail 56.
Preferably, the first end rail 54 is disposed substantially
parallel to the opposing end rail 56. Each end rail 54, 56 has a
first end 58 and a second end 60 and is preferably positioned along
the opposing orthogonal interior side walls 52 of the mounting
surface 14 of the table top 12. In one presently preferred
embodiment, the first end 58 of each end rail 54, 56 is disposed
within the channel 50 adjacent respective ends 62a, 62b of the
first side rail 42. Likewise, the second end 60 of each end rail
54, 56 is disposed within a channel 50 adjacent respective ends
64a, 64b of the second side rail 44, thereby providing a generally
rectangular shape to substantially correspond with the generally
preferable rectangular shape of the table top 12.
[0040] In one presently preferred embodiment of the present
invention, the first and second ends 58, 60 of respective end rails
54, 56 are configured with a tab member 66. The tab member 66 may
be configured to fit within respective channels 50 beneath the
retaining aperture 46 near the ends 62, 64 of the respective side
rails 42, 44 with the utility table 10 in an upright position. It
will be readily appreciated by those skilled in the art that, in
this configuration, the tab members 66 act as levers with the
support pedestals 18, 20 (positioned within the channels 50 near
the ends 62, 64 of the respective side rails 42, 44), thus acting
as corresponding fulcrums. In this manner, the end rails 54, 56
strengthen respective ends 68a, 68b of the table top 12, and
protect against bowing of the table top 12 at the ends 68a, 68b.
The first and second side rails 42, 44 in combination with the
first and second end rails 54, 56 provide a means for structurally
supporting the table top 12, the support pedestals 18, 20, and the
pivotal support braces 24, 30. In this configuration, lighter
weight table tops 12 may be used with this novel construction
without losing rigidity or structural integrity.
[0041] As will be appreciated, the end rails 54, 56 may interrelate
to the side rails 42, 44 in a variety of ways to provide structural
support for the utility table 10 and help protect against bowing
under various loads that may be applied to the utility table 10 For
example, the end rails 54, 56 may be welded to the side rails 42,
44. The end rails 54, 56 may also be bonded to the side rails 42,
44 using a variety of suitable epoxies or resins. Further, the end
rails 54, 56 and the side rails 42, 44 may be formed as a single
unitary piece configured to the desired size and shape. Moreover,
it will be also appreciated that the end rails 54, 56 and the side
rails 42, 44 need not interrelate at all, but could simply be
attached to the respective interior opposing side walls 48, 52 of
the mounting surface 14 of the table top 12.
[0042] In one presently preferred embodiment of the present
invention, the frame 40 is formed of a substantially sturdy, rigid
material sufficient to provide structural integrity to the table
top 12. For example, the frame 40 may be formed of metal. However,
it will be readily appreciated that the frame may be formed of a
wide variety of other suitable materials which are consistent with
the spirit and scope of the present invention. It will further be
appreciated that the size and configuration of the frame 40 will
depend, in part, on the size and configuration of the table top 12.
Accordingly, the table top 12 and the frame 40 may be configured in
a variety of shapes and configurations, including, but not limited
to, a circle, polygon, square, rectangle, triangle, or any other
suitable geometrical configuration.
[0043] Referring now to FIG. 3, the shape and size of the frame 40
is configured to generally conform to the periphery of the mounting
surface 14 of the table top 12.
[0044] Specifically, in one presently preferred embodiment of the
present invention, the frame 40 is attached in relation to the
mounting surface 14 by means of fasteners (not shown) which
generally penetrate both the frame 40 and an adjacent point of
contact of the mounting surface 14. As will be appreciated by those
skilled in the art, a variety of other suitable means or methods
for attaching the frame 40 to the mounting surface 14 of the table
top 12 may be employed, including, but not limited to, rivets,
screws, bolts, glues, epoxies, or other bonding materials.
[0045] As can be best seen in FIGS. 2 and 3, the mounting surface
14 of the table top 12 is preferably configured to facilitate the
attachment of the frame 40 to the mounting surface of the table top
12, in one presently preferred embodiment, the mounting surface 14
is configured with seats (not shown) positioned such that the end
rails 54, 56 may be positioned between respective opposing
orthogonal interior walls 52 and the seats (not shown). In this
configuration, the end rails 54, 56 are substantially prevented
from bowing inwardly toward the center of the utility table 10
under loads exerted upon the opposing ends of the table top.
[0046] It will be readily appreciated that the mounting surface 14
need not have interior side walls 48, 52 at all to practice the
teachings of the present invention. In this regard, the teachings
of the present invention may be practiced without a frame 40 if the
table top 12 is sufficiently rigid. It will further be appreciated
by those skilled in the art that in the embodiments where there is
110 frame, the support pedestals 18, 20 and cross brace member 36
may be attached to an interior portion of the mounting surface 14.
Further, in preferred embodiments where there are interior side
walls 48, 52 but no frame 40, the support pedestals 18, 20 and
cross brace member 36 may be positioned directly in retaining
apertures (not shown) formed within the interior side walls 48, 52
of the mounting structure 14 of the table top 12.
[0047] Referring back to FIG. 2, the support pedestals 18, 20 are
pivotally attached to the mounting surface 14, thereby permitting
each of the support pedestals 18, 20 to be moved between a
collapsed position, in which each support pedestal 18, 20 lies flat
in substantially the same plane as the table top 12, and an
extended position, in which each support pedestal 18, 20 is folded
outward, substantially perpendicular to the plane of the table top
12.
[0048] Each support pedestal 18, 20 may include a pair of
substantially parallel legs, or posts 80. Those of ordinary skill
in the art will appreciate that the teachings of the present
invention can be practiced if each support pedestal 18, 20 has more
or less than two posts 80. Each pair of posts 80 comprises a first
end 82 and a second opposing end 84. In one presently preferred
embodiment, the first end 82 of each respective pair of posts 80 is
secured to a cross pole 86. Respective ends 88 of each cross pole
86 are preferably positioned within opposing retaining apertures 46
disposed within the opposing side rails 42, 44 of the frame 40 such
that the support pedestals 18, 20 may be disposed substantially
parallel to each other. In this configuration, each cross pole 86
rotates within respective pairs of retaining apertures 46 when
respective pedestals 18, 20 move between the collapsed position and
the extended position. In one presently preferred embodiment, a
stabilizer arm 90 is preferably disposed between the respective
pairs of posts 80 to assist in structurally maintaining the
spaced-apart relationship of the posts 80.
[0049] It will be appreciated by those skilled in the art that the
support pedestals 18, 20 may be configured in a variety of ways
such that to practice the teachings of the present invention. For
example, the support pedestals 18, 20 may comprise a solid or
integral piece or the posts 80 may be curved in a different manner
(e.g., see FIG. 3). It will further be appreciated by those of
skill in the art that the support pedestals 18, 20 need not be in
pivotal engagement with the table top 12 to be collapsible. For
example, the support pedestals 18, 20 may simply be detachably
engaged in relation to the table top 12 such that when it is
desired to collapse the utility table 10 for storage, the support
pedestals 18, 20 are removed from selective engagement with the
table top 12.
[0050] As stated above, the first and second support pedestals 18,
20 are preferably connected to the table top 12 by means of the
first and second pivotal support braces 24, 30, respectively. In
one presently preferred embodiment of the present invention, the
proximal ends 26, 32 of the respective pivotal support braces 24,
30 are bifurcated to facilitate pivotal engagement with the posts
80 of the respective support pedestals 18, 20 as illustrated in
FIGS. 1, 2, and 3. The bifurcated proximal ends of the pivotal
support braces 24, 30 each preferably comprise a pair of angled
members 100.
[0051] Referring specifically to FIG. 2, the angled members 100 may
include a tab member 102 which pivotally engages and partially
overlaps a corresponding tab member 104 adjacent each of the distal
ends 28, 34 of the pivotal support braces 24, 30, respectively, at
an overlapping portion 106. When the support pedestals 18, 20 are
in the extended position, the tabs 102 of the angled members 100 of
the bifurcated proximal ends 26, 32 are disposed substantially
parallel to the tabs 104 adjacent each distal end 28, 34 of the
pivotal support braces 24, 30. When the support pedestals 18, 20
are in the collapsed position, the tabs 102 of the angled members
100 of the bifurcated proximal ends 26, 32 are disposed
substantially unparallel to the tabs 104 adjacent each distal end
28, 34 of the pivotal support braces 24, 30. The utility table 10
may include a pair of locking collars 108 which slidably engage
respective pivotal support braces 24, 30. The locking collars 108
are preferably sized to fit over respective overlapping portions
106 of the pivotal support braces 24, 30 when the support pedestals
18, 20 are in the extended position. With the locking collars 108
positioned over respective overlapping portions 106, the bifurcated
proximal ends 26, 32 are prevented from moving relative to
corresponding distal ends 28, 34 of the pivotal support braces 24,
30, thus preventing the support pedestal supports 18, 20 from being
positioned in the collapsed position without first disengaging the
locking collars 108, respectively. It will be appreciated by those
skilled in the art that with the utility table 10 in an upright
position and the support pedestals 18, 20 in the extended position,
the collars 108 may, under the force of gravity, position
themselves about the overlapping portions 106. It will be further
appreciated that a variety of other locking mechanisms as
assemblies may be utilized to lock the support pedestals 18, 20 in
the extended position which are consistent with the spirit and
scope of the present invention, including latches or other
fasteners.
[0052] With reference now to FIG. 3, the utility table 10 is shown
having an alternative configuration of the support pedestals 18,
20. In this alternate embodiment, each support pedestal 18, 20
comprises a first member 114 pivotally engaged to the mounting
surface 14 of the table top 12 and a second member 116 configured
for telescoping engagement with the first member 114, thereby
permitting the height of each support pedestal 18, 20 to be
selectively disposed at a plurality of predetermined heights
between a lengthened position and a retracted position.
[0053] In one presently preferred embodiment, each first member 114
of the support pedestals 18, 20 includes a pair of outer members
118 each having a proximal end 120 and a distal end 122. The
proximal end of each outer member 118 is connected to the table top
12 by means of the cross pole 86 to which they are preferably fixed
(e.g., welded). The second member 116 of each support pedestal 18,
20 includes a pair of inner members 124 each having a proximal end
126 and a distal end 128. The proximal end 126 of the inner members
124 are configured in dimensional size and shape to engage the
distal ends 122 of the outer members 118 in telescopic engagement.
It will be appreciated by those of ordinary skill in the art that
one or more stabilizer arms 90 may be employed to support the
telescopic pedestals 18, 20.
[0054] Preferably, the inner members 124 and outer members 118 are
separated by a hard plastic bushing (not shown) to facilitate the
slidable movement of the inner members 124 relative to the outer
members 118. Each bushing may be held in place with two small
extensions that extend through small holes (not shown) in the outer
members 118. It will be appreciated by those of skill in the art
that there are a number of ways to facilitate the telescopic
movement of the first member 114 relative to the second member 116
of each support pedestal 18, 20.
[0055] In the preferred embodiment illustrated in FIG. 3, the
support pedestals 18, 20 include means for locking the support
pedestals 18, 20 in preselected positions between the retracted
position and the lengthened position. At least one of the inner
members 124 is configured with a first hole 134. A corresponding
outer member 118 may be configured with at least one hole 136 and
preferably a plurality of holes 136 positioned such that at a
preselected table top 12 height the first hole 134 in the inner
member 124 may be aligned with a second hole 136 in the outer
member 118. In one presently preferred embodiment, a snap pin
mechanism 138 may be positioned adjacent the first hole 134 within
the inner member 124 such that the pin 138 is biased outwardly
through the aligned holes 134, 136, thereby locking the inner and
outer members 118, 124 of the support pedestals 18, 20 in a
preselected position. By supplying sufficient force to the pin
mechanism 138, it may be disengaged and removed from the hole 136
in the outer member 118, thereby permitting relative movement
between the inner 124 and outer 118 members of the support
pedestals 18, 20 and allowing the support pedestals 18, 20 to be
selectively raised or lowered. It will be appreciated by those
skilled in the art that a variety of other adjustment mechanisms as
assemblies known in the art for locking the first and second
support pedestals 18, 20 in an extended position may be utilized
and are herein incorporated.
[0056] As best shown in FIGS. 1, 2, and 3, the distal ends 28, 34
of each pivotal support brace 24, 30 are engageably secured to the
retaining assembly 36 (e.g., cross brace member). In one presently
preferred embodiment of the present invention, the distal ends 28,
34 of each pivotal support brace 24, 30, respectively, are
pivotally attached to the retaining assembly 36. Each of said
distal ends 28, 34 are configured with an opening 142 having an
interior periphery sufficient for engaging at least a portion of
the linear length of the cross-brace member 36.
[0057] It will be appreciated by those skilled in the art that the
retaining assembly 36 generally provides structural support to the
center of the table top 12 of the utility table 10. It will further
be appreciated that with the distal ends 28, 34 attached contiguous
each other in retention to the cross brace member 36 forces applied
to the table top 12 which would ordinarily be transferred through
one of the support pivotal braces 24, 30, respectively, into the
table top 12 causing it to bow, will substantially be nullified by
the counter force provided by the opposing pivotal support brace
24, 30, respectively.
[0058] For example, the horizontal component of a force applied by
a user at one end 68a of the table top 12 will act upon the pivotal
support brace 18 and, because the distal ends 28, 34 of the pivotal
support braces 24, 30, respectively, are attached to the retaining
assembly 36, an equal and opposite horizontal force component
applied by the other pivotal support brace 20 will substantially
cancel out the horizontal component of the original force.
Accordingly, the present invention provides increased structural
support to the table top 12 with fewer parts. As will be
appreciated by those skilled in the art, the retaining assembly 36
can be disposed in a variety of configurations which are consistent
with the spirit and scope of the present invention so as to allow
the pivotal support braces 24, 30 to supportably interrelate with
each other. Such alternative configurations are discussed
below.
[0059] With reference to FIGS. 1, 2, and 3, the table top 12 is
preferably formed of a blow-molded plastic, and specifically, high
density polyethylene. It will be appreciated by those of skill in
the art, however, that the table top 12 may be formed of a variety
of other sufficiently sturdy materials such as, plywood, particle
board, solid wood, wood slates, metal alloys, fiberglass, ceramics,
graphite, any of numerous organic, synthetic or processed
materials, including thermoplastic or thermosetting polymers of
high molecular weight with or without additives, such as,
plasticisers, auto oxidants, extenders, colorants, ultraviolet
light stabilizers, or fillers and/or other composite materials.
[0060] Referring back to FIG. 1, in one presently preferred
embodiment of the present invention, the working surface 16 of the
table top 12 may be smooth or, in the alternative, textured, if
desired. In addition, the working surface 16 may comprise an outer
periphery 144 having at least a portion 146 which is beveled to
increase the comfort of a person resting their arms against the
edges of the table top 12. In one presently preferred embodiment,
the entire outer periphery 144 of the working surface 16 of the
table top 12 is beveled. The height of the blow-molded table top 12
of one presently preferred embodiment is about five centimeters,
the thickness of any pan 13 of the blow-molded table top 12 is
preferably about one-half of a centimeter to about three-quarters
of a centimeter.
[0061] Referring now to FIGS. 2 and 3, the mounting surface 14 may
include at least one mounting member 148. Preferably, a pair of
mounting members 148 is attached to the mounting surface 14 to
receive and retain the cross brace member 36 of the retaining
assembly. Each mounting member 148 includes a groove 150 configured
as a corresponding size and shape sufficient to retain the cross
brace member 36 therein. In one presently preferred embodiment, the
cross brace member 36 may be snap fit into the groove 150 of the
mounting member 148.
[0062] In greater detail, as shown in FIG. 2, the mounting member
148 preferably includes an engagement portion 148a, and an opening
148b to the groove 150. The engagement portion 148a, the opening
148b, and the groove 150 cooperate to retain the cross brace member
36 within the mounting member 148. For example, the cross brace
member 36 is preferably snap fit into the groove 150 of each
mounting member 148 by pushing the cross brace member 36 into the
opening 148b of the mounting member 148. The opening 148b
preferably has a size slightly smaller than the size of the cross
brace member 36. Because the cross brace member 36 is slightly
larger than the opening 148b, the engagement portion 148a of the
mounting member 148 temporarily deforms to allow the cross brace
member 36 to enter the groove 150. When the cross brace member 36
is inserted into the groove 150, the engagement portion 148a
returns to its normal position and the cross brace member 36 is
securely retained by the mounting member 148.
[0063] The mounting member 148 may also have one or more supporting
portions 148c. The supporting portions 148c desirably securely
attach the mounting member 148 to the mounting surface 14 of the
table top 12. As shown in the accompanying figures, the supporting
portions 148c preferably extend longitudinally along the length of
the table 10 and they have a sloped or curved outer surface that
extends from the engagement portion 148a to the mounting surface 14
of the table top. One skilled in the art will readily appreciate
that the mounting member 148 may have other suitable shapes and
configurations depending, for example, upon the size and
combination of the cross brace member 36 to be attached to the
table top 12.
[0064] Advantageously, the mounting member 148 may be integrally
formed as part of a one-piece structure with the table top 12. In
particular, the mounting member 148 is preferably constructed as an
integral part of the table top 12 when it is formed from a
blow-molded plastic such as high density polyethylene.
Significantly, if the mounting member 148 is integrally formed as
part of the table top 12, the mounting member 148 does not have to
be screwed, bolted, bonded or otherwise connected to the mounting
surface 14 of the table top. Thus, the integrally formed mounting
member 148 does not compromise the integrity or decrease the
strength of the table top 12 by requiring the mounting member to be
screwed, bolted or bonded to the table top. One skilled in the art,
however, will understand that the mounting member 148 could be
connected to the table top 12 by any suitable mechanism or method
such as fasteners, adhesives and the like.
[0065] Additionally, the mounting surface 14 of the table top 12
may further include one or more securing members 152 for securing
each of the support pedestals 18, 20, respectively. Preferably, a
pair of securing members 152 are disposed in relation to the
mounting surface 14 for releasably securing a respective support
pedestal 18, 20 in the collapsed position adjacent the mounting
surface 14. Each securing member 152 is generally configured and
disposed relative to the mounting surface 14 such that when the
support pedestals 18, 20 are in the collapsed position, at least
one securing member 152 frictionally engages a support pedestal
post 80 such that the support pedestals 18, 20, respectively, are
maintained in the collapsed position, as illustrated in FIG. 3. In
one presently preferred embodiment, a pair of securing members 152
are offset on opposing sides of a single support pedestal post 80
for securing each of the support pedestals 18 or 20, respectively,
in the collapsed position. It will be apparent that other
mechanisms may be constructed in accordance with the inventive
principles set forth herein for securing the support pedestals 18,
20 in the collapsed position. It is intended, therefore, that the
examples provided herein be viewed as exemplary of the principles
of the present invention, and not as restrictive to a particular
structure for implementing those principles.
[0066] It will also be apparent that the securing members 152 may
be configured to contact any desired portion of the support
pedestals. For example, the securing members 152 may be configured
to engage post 80 along either the first member 114, as shown in
FIG. 3, the second member 116, or both, if desired. Alternatively,
securing members 152 could be disposed on the mounting surface 14
to engage both posts 80 of a respective support pedestal 18, 20.
One skilled in the art will appreciate that the securing members
152 could be disposed in any suitable positions depending, for
example, upon the desired portion of the support pedestal to be
engaged by the securing members.
[0067] In greater detail, as shown in FIGS. 2 and 3, each securing
member 152 desirably includes an engagement portion 152a, a
receiving portion 152b and a support portion 152c. The engagement
portion 152a includes a lip or forwardly extending extension that
overhangs at least a portion of the receiving portion 152b. The
receiving portion 152b is sized and configured to receive a portion
of the support pedestal 18, 20, such as the post 80. The support
portion 152c supports the securing member 152 in the desired
location.
[0068] The engagement portion 152a and receiving portion 152b of
the securing member 152 cooperate to releasably secure a respective
support pedestal 18, 20 in the collapsed position. For example,
when it is desired to move a support pedestal 18, 20 into the
collapsed position, the pedestal is pivoted towards the mounting
surface 14 of the table top 12. As the support pedestal 18, 20
approaches the table top 12, a portion of the support pedestal
contacts the engagement portion 152a. This contact causes the
engagement portion 152a to temporarily deform or move to allow a
portion of the support pedestal 18, 20 to be received by the
receiving portion 152b. Once the support pedestal 18, 20 is
received within the receiving portion 152b, the engagement portion
152a returns to its original shape or position, and that prevents
the support pedestal 18, 20 from being inadvertently released from
the securing member 152. The support pedestal 18, 20 is now secured
in its collapsed position within the securing member 152, as shown
in FIG. 3. When it is desired to move the support pedestal 18, 20
from the collapsed position to an extended position, the support
pedestal is simply pivoted away from the mounting surface 14 of the
table top 12 with a force sufficient to remove the support pedestal
from the receiving portion 152b and past the engagement portion
152a, thereby removing the support pedestal from the securing
member 152.
[0069] As seen in FIGS. 2 and 3, the receiving portion 152b
preferably has a curved surface to receive the support pedestal 18,
20. In particular, the receiving portion 152b preferably has a
concave surface and the engagement portion 152a includes an
extension or lip that extends at least partly beyond the concave
surface of the receiving portion 152b. Advantageously, the
engagement portion 152a and receiving portion 152b allow the
support pedestal 18, 20 to be snap fit into the securing member
152. One skilled in the art will appreciate that the engagement
portion 152a and receiving portion 152b may have other suitable
configurations depending, for example, upon the shape and
configuration of the support pedestal 18, 20 or the position of the
support pedestal to be releasably secured by the securing member
152.
[0070] The securing member 152 preferably includes one or more
support portions 152c to securely attach the securing member 152 to
the mounting surface 14 of the table top 12. As shown in the
accompanying figures, the supporting portion 152c preferably
extends in the opposing direction as the receiving portion 152b and
has a sloped or curved outer surface that extends from the
engagement portion 152a to the mounting surface 14 of the table top
12. One skilled in the art will understand that the securing member
152 may have other suitable shapes and configurations depending,
for example, upon the size and configuration of the portion of the
support pedestal 18 20 to be releasably secured.
[0071] Advantageously, the securing member 152 may be integrally
formed as part of a one-piece structure with the table top 12. In
particular, the securing member 152 is preferably constructed as an
integral part of the table top 12 when it is formed from a
blow-molded plastic such as high density polyethylene.
Significantly, if the securing member 152 is integrally formed as
part of the table top 12, it does not have to be screwed, bolted,
bonded or otherwise connected to the mounting surface 14 of the
table top. Thus, the integrally formed securing member 152 does not
compromise the integrity or decrease the strength of the table top
12 by requiring the securing member to be screwed, bolted or bonded
to the table top. One skilled in the art, however, will understand
that the securing member 152 could be connected to the table top 12
by any suitable mechanism or method such as fasteners, adhesives
and the like.
[0072] As best shown in FIGS. 2 and 3, a first manifold 154 and a
second manifold 156 are preferably disposed at opposing ends 68a,
68b of the table top 12. The manifolds 154, 156 provide additional
support for the ends 68a, 68b of the table top 12 and assist in
facilitating the blow molding process by providing a means for
uniformly dispersing air down the length of the table top 12. The
mounting surface 14 of the table top 12 may also include a
plurality of depressions 158 (e.g., kiss-offs) which tend to add
structural support and integrity to the table top 12. In one
presently preferred embodiment, these depressions 158 are uniformly
distributed throughout the mounting surface 14 of the table top
12.
[0073] The structural features of the table top 12, including the
beveled edges and/or textured working surface 16, the mounting
members 148, the securing members 152, the manifolds 154, 156, and
the depressions 158 may be integral with the table top 12 and may
be formed by means of a corresponding mold and blow-molding
process. It will be appreciated by those skilled in the art that
there are alternative ways to create and attach these features. For
example, the mounting members 148, securing members 152, and
manifolds 154, 156 may be separate pieces that are attached to the
mounting surface 14 by adhesive bonding or the use of conventional
fasteners. Likewise, the texturing and/or beveling of the edges of
the working surface of the table top and the introduction of
depressions into the mounting surface may also be accomplished
after the table top 12 is molded by a variety of conventional
methods readily known in the art.
[0074] As best illustrated in FIG. 1, when the utility table 10 is
disposed in an upright position in relation to an underlying
surface and the support pedestals 18, 20 extended with the collars
108 placed over the overlapping portions 106 of the respective
pivotal support braces 24, 30, the utility table 10 of the present
invention is positioned for use. When a user desires to collapse
the utility table 10 for storage, one presently preferred method
for doing so is to invert the utility table 10, as shown in FIG. 3.
With the utility table 10 in the inverted position, the collars 108
may be slid away from engagement with the overlapping portion 106
of the respective pivotal support braces 24, 30. This allows the
support pedestals 18, 20 to be folded inwardly toward the table top
12 into the collapsed position. With the support pedestals 18, 20
in the collapsed position, the utility table 10 can easily be moved
and stored.
[0075] With reference now to FIG. 4, another presently preferred
embodiment of the utility table of the present invention is
generally designated at 210. In this embodiment, the utility table
210 includes a table top 12 having a mounting surface 14 and a
working surface 16 disposed opposite the mounting surface 14. A
first support pedestal 18 and a second support pedestal 20 are
pivotally attached to the mounting surface 14 of the table top 12.
Preferably, the first and second support pedestals 18 20 are
independently attached to a support bar 212 having opposing ends
211 configured to engage receiving apertures 46 formed in opposing
side rails 42, 44 of a rigid flame 40 supportably disposed in
relation to the table top 12.
[0076] In one presently preferred embodiment, the support bar 212
is configured having a bend formed at its opposing ends 211 to
ensure that the first and second support pedestals 18, 20,
respectively, fold properly against the mounting surface 14 of the
table top 12 when disposed in the collapsed position As
appreciated, the slight bend formed at the opposing ends 211 of the
support bar 212 has the structural effect of extending the central
portion of the support bar 212 away from the axis of rotation of
the support bar 212 relative to the frame 40. Moreover, the bending
configuration of the support bar 212 at its opposing ends 211
provides additional safety, in proportion to the weight applied
against the table top 12, by maintaining the first and second
support pedestals 18 and 20 in the extended position
[0077] The support bar 212 may be omitted from engagement with the
proximal end 120 of the support pedestals 18, 20 in favor of a
suitable attachment assembly designed to facilitate pivotal
engagement between the support pedestals 18, 20 and the mounting
surface 14 of the table top 12. Those skilled in the art will
readily recognize other possible modifications and adaptations
which are consistent with the spirit and scope of the present
invention and which are herein contemplated by the present
invention.
[0078] Still referring to FIG. 4, the utility table 210 of the
present invention may include each first member 114 of the support
pedestals 18, 20 having a pair of outer members 118 each having a
proximal end 120 and a distal end 122. The proximal end of each
outer member 118 is connected to the table top 12 by means of the
support bar 212 to which they are preferably fixed (e.g., welded).
The second member 116 of each support pedestal 18, 20 includes a
pair of inner members 124 each having a proximal end 126 and a
distal end 128. The proximal end 126 of the inner members 124 are
configured in dimensional size and shape to slidably engage the
distal ends 122 of the outer members 118 in telescopic
engagement.
[0079] Preferably, the inner members 124 and outer members 118 are
separated by a hard plastic bushing (not shown) to facilitate the
slidable movement of the inner members 124 relative to the outer
members 118. Each bushing may be held in place with two small
extensions that extend through small holes (not shown) in the outer
members 118. It will be appreciated by those of skill in the art
that there are numerous ways to facilitate the telescopic movement
of the first member 114 relative to the second member 116 of each
support pedestal 18, 20 which are readily contemplated herein. It
is also contemplated herein that the length of the support
pedestals 18, 20 may be fixed and, thus not selectively adjustable
to a plurality of heights.
[0080] As illustrated in FIG. 4, an elongated foot member 213 may
be rigidly attached at the distal end 128 of each of the inner
members 124 of the support pedestals 18, 20 so as to provide
additional stability to the table top 12 when disposed in the
upright position.
[0081] Preferably, the foot member 213 facilitates a more even
dispersion of the supportable weight of the utility table 210 over
a greater portion of the underlying surface in addition, because
the length of the foot member 213 tends to span the distance
between the first and second members 114, 116, one or more
stabilizer arms 90 may be unnecessary.
[0082] Similar to the preferred embodiments of the utility table
illustrated in FIGS. 1-3, the utility table 210 includes a first
pivotal support brace 224 having a bifurcated proximal end 226
attached to the first support pedestal 18 and a distal end 228
pivotally attached to a first retaining assembly 36a. Similarly, a
second pivotal support brace 230 having a bifurcated proximal end
232 attached to the second support pedestal 20 and a distal end 234
pivotally attached to a second retaining assembly 36b. In one
presently preferred embodiment, each of the retaining assemblies
36a, 36b comprise a cross-brace member having opposing ends and an
intermediate body portion formed therebetween. Each of the distal
ends 228, 234 of the pivotal support braces 224, 230 are configured
with openings 242 having an internal periphery sufficient for
engaging at least a portion of the length of the intermediate body
portion of the cross-brace members 36a, 36b, respectively.
[0083] The opposing ends of the first and second cross-brace
members 36a, 36b, respectively, are configured so as to be
introduced and retained within corresponding retaining apertures 46
formed in opposing side rails 42, 44 of the frame 40 or, in the
alternative, within opposing, interior side walls of the table top
12. Preferably, the first and second cross-brace members 36a, 36b
are separated by a central portion 216 of the table top 12.
Structurally, this central portion 216 of the table top 12 must
have sufficient structural integrity to support a compressive load,
either through the frame 40, the entire surface of the table top
12, or by some combination of the two, when weight is applied
against the table top 12 to avoid bowing.
[0084] The dual cross-brace supportable configuration of the
utility table 210 of the present invention is advantageous because
the pivotal support braces 24, 30 obstruct less of the available
space beneath the table top 12 and between the support pedestals
18, 20 Consequently, more room is available to accommodate the legs
of one or more users beneath the table top 12, thereby making the
utility table 210 more comfortable to users. Furthermore, the
absence of the cross-brace members 36a, 36b from the central
portion 216 of the table top 12 provides usable storage space to
accommodate the foot members 213 when the support pedestals 18, 20
are disposed in the collapsed position. As will be appreciated by
those skilled in the art, the central portion 216 integrally formed
in the mounting surface 14 of the table top 12 may be configured
having a wider or narrower dimension than illustrated by way of
example in FIG. 4, depending on the overall extended length of the
table top 12, the supportable weight the table top is designed to
bear, the size of the foot members 213, and/or the need for usable
space beneath the table top 12 when the utility table 210 is
disposed in the usable position.
[0085] In one presently preferred embodiment, a pair of locking
collars 217 is provided which slidably engage respective
overlapping portions of the pivotal support braces 224, 230. The
locking collars 217 are preferably configured and sized such that
when the support pedestals 18, 20 are selectively disposed in the
extended position, the locking collars 217 may be engageably
positioned in relation to the overlapping portions to prevent the
bifurcated proximal ends 226, 232 from moving relative to the
corresponding distal ends 228, 234 of the pivotal support braces
224, 230, thus preventing the support pedestal supports 18, 20 from
being positioned in the collapsed position without first
disengaging the locking collars 217, respectively.
[0086] As with the previous preferred embodiments illustrated in
FIGS. 1-3, a plurality of kiss-offs 218 may be formed in the
mounting surface 14 of the table top 12 to add structural integrity
and strength to the working surface 16 of the blow molded table
top. In addition, a plurality of plateaus 219 and longitudinal
trenches 220 may also be formed in the mounting surface 14 to
further add stiffening and strength to the table top 12.
Correspondingly, these plateaus 219 and trenches 220 operably
function to increase the section modulus of the table top 12 by
moving material away from the neutral axis of the table top 12,
thus making it more difficult to bend the table top 12 in a
longitudinal direction, as when a heavy load is positioned in the
middle of the table top 12. As will be appreciated, the kiss-offs
218 may be formed within the trenches 220 to ensure that the table
top 12 can be made hollow without concern that the working surface
16 may have a tendency to flex inwardly toward the mounting surface
14 when a weight is placed on the table top 12.
[0087] Additionally, an opening 222 may be formed in the table top
12 to provide means for introducing a support pole of an umbrella
assembly (not shown) or the like. Although certain structural
elements and components, such as: (1) one or more stabilizer arms
90 engageably disposed in relation to the first and second member
114, 116 of the support pedestals 18, 20 (see FIGS. 2 and 3); (2)
one or more mounting members 148 for supportably retaining the
retaining assembly 36 in relation to the mounting surface 14 of the
table top 12 (see FIGS. 2 and 3); (3) one or more securing members
152 attached to the mounting surface 14 of the table top 12 for
securing the support pedestals 18, 20 in the collapsed position
(see FIGS. 2 and 3); (4) one or more manifolds 154, 156 that assist
in facilitating the blow molding process by providing for uniform
dispersion of air along the length of the blow molded table top 12
(see FIGS. 2 and 3); and (5) beveled edges and/or a textured
working surface 16 (see FIG. 1) have been omitted from the
embodiment of the utility table 210 illustrated in FIG. 4. It is
contemplated herein that one or more of these structural features,
however, may be incorporated into the alternate design of the
utility table 210, if desired.
[0088] With reference now to FIG. 5, another presently preferred
embodiment of the utility table of the present invention is
(generally designated at 310. As shown, the utility table 310
includes a table top 12 having a mounting surface 14 and a working
surface 16 disposed opposite the mounting surface. Structurally,
the table top 12 is preferably supported above an underlying
surface by a first support pedestal 18 and a second support
pedestal 20 disposed at spaced-apart relationship to the first
support pedestal. Both the first and second support pedestals 18,
20 are preferably attached to the mounting surface 14 or, in the
alternative, to a rigid support frame 40. A first pivotal support
brace 324 includes a proximal end 326 pivotally attached to the
first support pedestal 18 and a distal end 328 pivotally attached
to a retaining assembly 36. Similarly, a second pivotal support
brace 330 is shown having a proximal end 332 pivotally attached to
the second support pedestal 20 and a distal end 334 pivotally
attached to the retaining assembly 36 As will be appreciated, the
distal ends 328, 334 of the first and second pivotal support brace
324, 330, respectively, may be pivotally attached to the mounting
surface 14 by means of a engaging bracket (not shown).
[0089] Because the alternate preferred embodiment of the utility
table 310, as illustrated in FIG. 5, is substantially similar in
construction to the utility table 10 shown in FIGS. 1-3, only those
structural variations which exist between these two embodiments
will be further disclosed hereinbelow.
[0090] Specifically, one presently preferred embodiment of the
utility table 310 includes a first support pedestal 18 having two
support legs 312, 314. Each of the support legs 314, 312 of the
first support pedestal 18 may be formed having a proximate end 316
rigidly attached to a cross pole 86 mounted in pivotal relation to
the frame 40 or, in the alternative, to the mounting surface 14 of
the table top 12 independent of the other leg. Similarly, each of
the support legs 314, 312 of the second support pedestal 20 may be
formed having a proximate end 316 rigidly attached to a cross pole
86 mounted in pivotal relation to the frame 40 or, in the
alternative, to the mounting surface 14 of the table top 12
independent of the other leg.
[0091] To accommodate a table top 12 having a length that is
smaller than the fixed or extendable length of the legs 312, 314 of
the support pedestals 18, 20, the relative disposition of the
distal ends 318 of each of the support legs 312, 314 of the first
support pedestal 18 are offset from the corresponding distal ends
318 of each of the support legs 312, 314 of the second support
pedestal 20 disposed on an opposite side of the table top 12. The
distal end 318 of the first support leg 312 of the first support
pedestal 18 is offset in a lateral direction 320 from the second
support leg 314 of the first support pedestal. Similarly, the
distal end 318 of the first support leg 312 of the second support
pedestal 20 is offset in a lateral direction 320 from the second
support leg 314 of the second support pedestal 20. This offset
configuration enables the use of a smaller table top 12 and frame
40 because the support pedestals 18, 20 can include a length
greater than the distance between the opposing ends of the table
top 12, and yet still fold into a parallel configuration relative
to the mounting surface 14 of the table top 12 without interference
by the distal ends 318 of each of the support legs 312, 314 of the
first and second support pedestals 18, 20.
[0092] The foregoing function can be structurally accomplished in a
variety of ways. For example, both the proximal and distal ends
316, 318 of the support legs 312, 314 may be laterally offset so
that the legs 312, 314 are always parallel to the frame 40, as
shown in FIG. 5. Alternatively, the proximal ends 316 may remain
aligned in the folded position, and the legs 312, 314 may fold at
an angle. This may be done by pivotally mounting the proximal ends
316 to the mounting surface 14 at an angle, or by mounting the
cross pole 86 at a diagonal angle with respect to the frame 40 and
table top 12.
[0093] As discussed above, the retaining assembly 36 generally
provides structural support to the center of the table top 12 of
the utility table 310. It will be further appreciated that with the
distal ends 328, 334 attached contiguous each other in retention to
the cross-brace member 36, forces applied to the table top 12 which
would ordinarily be transferred through one of the support pivotal
braces 324, 330, respectively, into the table top 12 causing it to
bow, will substantially be nullified by the counter force provided
by the opposing pivotal support brace 324, 330, respectively.
[0094] For example, the horizontal component of a force applied by
a user at one end of the table top 12 will act upon the one of the
support pedestals 18, 20 and, because the distal ends 328, 334 of
the pivotal support braces 224, 330, respectively, are attached to
the retaining assembly 36, an equal and opposite horizontal force
component applied by the other pivotal support brace 18, 20 will
cancel out the horizontal force component of the original force.
Accordingly, although the support legs 212, 214 of the support
pedestals 18, 20 are offset, the structural configuration of the
present invention provides increased structural support to the
table top 12 with fewer parts. As will be appreciated by those
skilled in the art, the retaining assembly 36 may be disposed in a
variety of configurations which are consistent with the spirit and
scope of the present invention so as to slow the pivotal support
braces 324, 330 to supportably interrelate with each other.
Moreover, the utility table 210 shown in FIG. 4 and discussed in
detail hereinabove, may include support pedestals 18, 20 that
comprise spaced apart support legs which are offset from the
corresponding support legs of the opposing support pedestal to
provide the advantages of overlapping the legs, if desired.
[0095] Although certain structural elements and components, such
as: (1) telescoping support legs operable to adjust the height of
the table top 12 above an underlying surface, (2) a second
cross-brace member 36b formed independent of a first cross-brace
member 36a (see FIG. 4); (3) a plurality of kiss-offs 158 formed in
the mounting surface 14 of the table top 12 (see FIGS. 2 and 3),
(4) one or more mounting members 148 for supportably retaining the
retaining assembly 36 in relation to the mounting surface 14 of the
table top 12 (See FIGS. 2 and 3), (5) one or more securing members
152 attached to the mounting surface 14 of the table top 12 for
securing the support pedestals 18, 20 in the collapsed position
(see FIGS. 2 and 3); (6) one or more manifolds 154, 156 that assist
in facilitating the blow molding process by providing for uniform
dispersion of air along the length of the blow molded table top 12
(see FIGS. 2 and 3); (7) a bend formed in the opposing ends 211 of
the support bar 212 (see FIG. 4); (8) beveled edges and/or a
textured working surface 16 (See FIG. 1); and (9) a plurality of
plateaus 219 and longitudinal trenches 220 may also be formed in
the mounting surface 14 to further add stiffening and strength to
the table top 12 (see FIG. 4) have been omitted from the embodiment
of the utility table 310 illustrated in FIG. 5. It is contemplated
herein that one or more of the foregoing structural however, may be
incorporated into the design of the utility table 310, if
desired.
[0096] Many of the problems associated with prior art portable
folding utility tables are addressed by the teachings of the
present invention. From the above discussion, it will be
appreciated that the present invention provides a novel portable
folding utility table having a center support assembly that is
durable enough to withstand increased wear and tear, yet is
lightweight enough to easily set up and take down. The present
invention also provides a utility table with a center support
retaining assembly that provides increased stability and structural
integrity with an efficient design that allows the interrelation of
the support pedestals to each other. The center support retaining
assembly of the utility table of the present invention is also cost
effective to manufacture and does not compromise the structural
integrity of the table top. The present invention also provides a
portable folding utility table that includes a work surface
disposed at a height that is comfortable to work at. Additionally,
features are provided to improve the functionality of longer and
smaller tables under various use and loading conditions.
[0097] It should be appreciated that the apparatus of the present
invention is capable of being incorporated in the form of a variety
of embodiments, only a few of which have been illustrated and
described above. The invention may be embodied in other forms
without departing from its spirit or essential characteristics. The
described embodiments are to be considered in all respects only as
illustrative and not restrictive. The scope of the invention is,
therefore, indicated by the appended claims rather than by the
foregoing description. All changes which come within the meaning
and range of equivalency of the claims are to be embraced within
their scope.
