BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention generally relates to furniture and, in
particular, to tables.
[0004] 2. Description of Related Art
[0005] Many different types of tables are well known and used for a
variety of different purposes. For example, conventional tables may
include legs that are pivotally attached to a table top and the
legs may be movable between a use position in which the legs extend
outwardly from the table top and a storage position in which the
legs are folded against the table top. Conventional tables with
relatively large table tops and folding legs are often referred to
as "banquet tables" and these tables are frequently used in
assembly halls, banquet halls, convention centers, hotels, schools,
churches and other locations where large groups of people meet.
Because these conventional tables are generally easy to move and
relatively portable, these types of tables can often be positioned
in an assortment of different configurations and used in a variety
of settings. When the tables are no longer needed, the table legs
can be moved into the storage position and the tables may be moved
or stored.
[0006] Conventional banquet tables with collapsible legs may allow
the table to be more conveniently stored. The table top for many
conventional banquet tables with collapsible legs, however, retains
its size and shape. For example, many known banquet tables have a
length between six to ten feet and a width between three to four
feet. As a result, the storage of many conventional banquet tables,
even with the legs in the collapsed position, may require a large
storage area. This large storage area for each table may be
problematic for large facilities such as hotels, schools and
churches because a considerable number of these table may have to
be stored. Thus, a big area may be required to store the tables. In
addition, smaller facilities such as restaurants, offices and homes
may use one or more conventional banquet tables. These smaller
facilities may use the tables less frequently, such as during
special occasions. Conventional banquet tables, even when the legs
are folded, are often too bulky and obstructive to be conveniently
used and stored at such smaller facilities. As a result, it is
often necessary for both larger and smaller facilities to rent
and/or borrow one or more banquet tables when needed.
Disadvantageously, this process of renting and/or borrowing banquet
tables can be inconvenient, time consuming and costly.
[0007] In addition, conventional banquet tables are often very
difficult to move or transport from one location to another. For
example, because of the length of many conventional banquet tables,
the tables are often difficult to move by a single person. In
addition, the extended length of the banquet tables may preclude
the tables from being transported in the trunk or back seat of a
typical passenger car. Accordingly, the banquet tables may have to
be transported by a truck or trailer, which may be difficult to
obtain, expensive and require a significant amount of time.
[0008] It is also known to construct tables that are capable of
being folded-in-half. In particular, conventional fold-in-half
tables typically include a table top with two sections that are
pivotally connected by a hinge. The two sections of the table top
may be moved between an unfolded position or use position in which
the sections of the table top are generally aligned in the same
plane and a folded position in which the two sections are
positioned generally adjacent to each other for storage.
[0009] Disadvantageously, many known tables with foldable table
tops are unstable and unable to support a significant amount of
weight. For example, the connection of the two table top sections
of many known fold-in-half tables may be relatively weak, which may
allow, for example, a portion of the table top to sag. In order to
construct a stronger table top, it is known to make foldable table
tops out of stronger and thicker materials. Undesirably, this may
increase the weight of the table top, which may make the table more
difficult to carry and move.
[0010] Many conventional tables with foldable table tops also
include hinges that connect the two portions of the table top and
the hinges are often connected to the table top by a plurality of
screws that are bored into the table top. Disadvantageously, the
structural integrity of the table top may be decreased by the holes
created by the plurality of screws, and this may allow the table to
collapse and fail. In addition, because the screws are typically
individually attached to the table top, this may significantly
increase the amount of the time required to construct the table.
Further, this may increase the manufacturing time and costs to make
the table.
[0011] Additionally, known tables with foldable table tops are
often difficult to transport and store because it may be hard to
maintain the table top in the closed position, especially for a
single person. In particular, the table tops of many known foldable
tables can unintentionally swing between the folded and unfolded
position while the tables are being moved, positioned and/or
stacked. That is, while the table is being moved, the table top may
inadvertently move from the folded to the unfolded position. If
this occurs, the table may be undesirably dropped, and this may
damage the table and/or injure the person carrying the table.
[0012] Further, when conventional fold-in-half tables are in the
folded or storage position, it may be difficult to lift and move
the table because it may be hard to grasp the table. In particular,
the tables may be difficult to carry because there no convenient
handholds or portions of the table to grab. In addition to many
conventional fold-in-half tables being difficult to grasp and move
in the folded position, this problem may be exasperated by the
table top unintentionally unfolding while the table is being
moved.
BRIEF SUMMARY OF THE INVENTION
[0013] A need therefore exists for a table that reduces or
eliminates the above-described and other disadvantages and
problems.
[0014] One aspect is a table that may include a table top and one
or more legs or support pedestals that may be used to support the
table top in a use or support position. The legs or support
pedestals are preferably movable between an extended or use
position and a collapsed or storage position relative to the table
top. Advantageously, when the legs or support pedestals are in the
use position, the table may be used to support a wide variety of
objects and the table may be used for a variety of different
purposes.
[0015] Another aspect is a table that may include a table top that
is capable of being moved between a folded position and an unfolded
position. Preferably, the table top includes two sections and the
two sections are generally aligned in the same plane when the table
top is in the unfolded position and the two sections are generally
positioned adjacent to each other when the table top is in the
folded position. The table may also include legs that are movable
between a use position and a collapsed position. Advantageously, if
the table includes both a foldable table top and foldable table
legs that can be selectively moved between use and collapsed
positions, then the table may be stored in a relatively compact
area. This may allow, for example, a single person to easily move
and transport the table. In addition, this may allow the table to
be positioned in a relatively small area, such as the backseat or
trunk of an automobile. Further, this may allow one or more tables
to be shipped and/or stored in relatively small areas.
[0016] Yet another aspect is a table that may include a table top
constructed from plastic and the plastic table top is preferably
constructed using a blow-molding process. Advantageously, this may
allow a lightweight table top to be easily constructed and it may
allow the table top to be formed into various desired
configurations, shapes, sizes and designs. This may also allow a
table top to be constructed that is generally weather resistant and
temperature insensitive, which may allow the table to be used in a
wide variety of locations and environments. In addition, this may
allow a table top that is durable, long-lasting and corrosion
resistant to be constructed. Further, because a table top
constructed from blow-molded plastic may be relatively strong, the
table may be used to support a relatively large amount of weight.
Significantly, a table top constructed from blow-molded plastic may
also form a structural member of the table, but the table top may
be supported by other structures, such as a frame.
[0017] Advantageously, a table top constructed from blow-molded
plastic may be relatively strong because it includes opposing walls
or surfaces that are separated by a distance. The opposing walls
may help create a high-strength, rigid table top. In addition,
because the interior portion of the table top may be generally
hollow, that may create a lightweight table top. Thus, the
blow-molded table top may be both lightweight and strong.
[0018] Still another aspect is a table that may include a table top
that includes two sections. For example, the table top may include
a first table top section and a second table top section, and each
section may include an inner edge or portion. Desirably, the inner
edges or portions of the first and second table top sections engage
or contact when the table top is in the extended or use position,
and the inner edges or portions are spaced apart from each other in
the folded position. Advantageously, the inner edges or portions
may be sized and configured to engage and/or overlap to allow, for
example, a secure connection of the first and second sections when
the table top is in the extended or use position. For instance, the
inner edges or portions of the table top sections may include one
or more projections and/or recesses that are sized and configured
to contact or engage when the table top is in the extended or use
position. In particular, the inner edges or portions may include
tongue and groove portions which matingly engage when the table top
is in the extended or use position. That is, the inner edge or
portion of the first table top section may have one or more tongue
and/or groove portions that are aligned with corresponding tongue
and/or groove portions in the inner edge or portion of the second
table top section. The table top sections are preferably configured
so that the tongue and groove portions interlock when the table top
is in the extended or use position. Advantageously, this may
increase the strength and rigidity of the table top, which may
allow the table top to be constructed of a lighter and/or thinner
material without sacrificing strength or integrity.
[0019] A further aspect is a table that may include two sections
that are movable between a folded and unfolded position, and the
table may include a handle. Advantageously, this handle may allow
the table to be more easily transported or moved. For example, the
handle can be mounted to a portion of the table top such that the
handle may project between the edges of the table top sections when
the table top is in the folded position. In this configuration, a
single individual may easily gasp the projecting handle to carry
the table. The table may also include a handle retention assembly
that may be used to secure the handle in a desired position. In
particular, the handle retention assembly may advantageously secure
the handle in a generally fixed position. For instance, the handle
retention assembly may secure the handle in a generally fixed
position that is out of the way and not obstructive when the table
top is in the unfolded position.
[0020] Another aspect is that the table may be easily assembled
and/or disassembled. For example, the table may not include any
heavy or complex mechanisms to attach the table legs to the table
top and/or to connect the first and second sections of the table
top. In particular, the table may include a frame that quickly and
easily attaches the legs to the table top. For instance, the frame
may include two elongated side rails and the side rails may be
connected to one or more frame mounting portions. Advantageously,
the frame mounting portions may be integrally formed in the table
top and the frame can be attached to the table top by a snap,
friction or interference fit. Significantly, this may allow the
frame to be attached to the table top without mechanical fasteners
such as screws or bolts, but mechanical fasteners may be used if
desired. Because mechanical fasteners are not required to attach
the frame to the table top, fewer parts may be required to assemble
the table and holes do not have to be formed in the table top. This
may also allow the table to be quickly and easily manufactured and
assembled. Further, fewer workers may be required to assemble the
table and the relatively straight forward design and attachment of
the frame to the table top may allow the table to be shipped either
assembled or unassembled, which may allow retailers or consumers to
assemble the table if desired.
[0021] Still another aspect is a table that may include a table top
with sections that are interconnected. For example, a frame may be
attached to the sections of the table top and the frame may be
sized and configured to allow the table top to be moved between the
folded and unfolded positions. In particular, the frame may include
side rails that are connected to the sections of the table top and
one or more hinge assemblies may be connected to the side rails.
The hinge assemblies may enable the table top to move between the
folded and unfolded positions. Preferably, the hinge assemblies are
mounted directly to the frame and the hinge assemblies are not
connected to the table top. Because mechanical fasteners are not
required to attach the hinge assemblies to the table top, fewer
parts may be required to assemble the table and holes do not have
to be formed in the table top, which may allow the table to be
quickly and easily manufactured and assembled. Because the hinge
assemblies do not have to be separately mounted directly to the
table top by screws or other fasteners, this may allow retailers or
consumers to assemble the table if desired.
[0022] Still yet another aspect is a table that may include a table
top with sections that are interconnected by one or more hinge
assemblies to allow the table top to be moved between folded and
unfolded positions. The table preferably includes a mechanism, such
as a bolt, that is slidable or movable relative to the table top
between a first position and a second position. For example, when
the table top is in the unfolded position, the bolt may be sized
and configured to lock a hinge assembly and/or a portion of the
frame in a generally fixed position to secure the table top in the
unfolded position. The bolt may also be moved to unlock the hinge
assembly and/or the frame to allow the table top to be moved into
the folded position. Advantageously, the bolt may secure the table
top in the unfolded position and prevent the table from
unintentionally folding.
[0023] A further aspect is a table that may include one or more
legs that are movable between an extended position and a collapsed
position relative to the table top. The legs may be connected to a
cross member and the cross member may be connected to the
frame.
[0024] A still further aspect is a table that may include a
retainer which may be connected to a first portion of the table
top. Advantageously, the retainer may be sized and configured to
secure the table top in a closed or folded position. For example,
the retainer may include a first end that is connected to a first
portion of the table top, such as a cross member or a portion of
the frame. The second end of the retainer may be sized and
configured to be attached to a second portion of the table top when
the table top is in the closed or folded position. In particular,
the second end of the retainer may be connected to a cross member
or a portion of the frame. Preferably, the second end of the
retainer is selectively connected to the second portion of the
table top to allow the table top to be folded and unfolded.
Significantly, the retainer may help retain the table top in the
folded position so that the table top does not unintentionally
unfold when the folded table is being carried, transported and/or
stored. The retainer may also be sized and configured to
automatically engage the second portion of the table top, which may
simplify the engagement process. In addition, the retainer may be
selectively connected to the first portion of the table top, which
may simply the manufacturing process and allow the retainer to be
quickly and easily attached.
[0025] Yet still another aspect is a table that may include a brace
that is connected to one or more of the legs. In particular, the
brace may include a first end that is connected to the table top
and a second end that is connected to the leg. The brace is
preferably sized and configured to support the leg in an extended
position relative to the table top. The brace, which may be any
suitable type of brace such as a slotted brace, may be biased to
secure the leg in the extended position. For example, the brace may
include a pin that is disposed within a slot and the brace may
include a biasing member, such as a spacer or washer. The biasing
member may be constructed from a deformable and resilient material,
such as rubber, which may be used to bias the brace into a desired
position. For example, the brace may be biased to lock the brace in
a generally fixed position, which may secure the leg in the
extended position.
[0026] 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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0049] The present invention is generally directed towards a table
that includes a table top that are capable of being folded in half
The principles of the present invention, however, are not limited
to a table with a table top that is capable of being folded in
half. It will be understood that, in light of the present
disclosure, the tables and various portions of the tables disclosed
herein can be successfully used in connection with other types of
furniture and structures.
[0050] Additionally, to assist in the description of the tables,
words such as top, bottom, front, rear, right and left are used to
describe the accompanying figures. It will be appreciated, however,
that the tables can be located in a variety of desired positions
and the tables can have various suitable shapes, sizes and
configurations. A detailed description of exemplary embodiments of
the table now follows.
[0051] As shown in FIGS. 1 and 2, an exemplary embodiment of a
table 10 includes a table top 12 with an upper surface 14, a lower
surface 16, a first end 18, a second end 20, a front side 22 and a
rear side 24. The upper surface 14 of the table top 12 is
preferably generally planar to create a relatively smooth and flat
working surface, but the upper surface could also be textured and
have other suitable shapes and configurations depending, for
example, upon the intended use of the table 10. The table top 12
may also include an outer edge 26 that is disposed about a
perimeter or periphery of the table top. All or a portion of the
outer edge 26 of the table top 12 may be beveled, sloped, rounded
and the like according to, for example, the intended design and/or
aesthetics of the table 10.
[0052] The table top 12 may also include a generally downwardly
extending lip 28 that is disposed near or at the outer edge 26 of
the table top. The lip 28 preferably extends downwardly beyond the
lower surface 16 of the table top 12 and the lip may be aligned
with and/or form a part of the outer edge 26 of the table top. It
will be appreciated that all or a portion of the lip 28 may also be
spaced inwardly from the outer edge 26 of the table top 12. As
discussed below, the lip 28 may be integrally formed with the table
top 12 as part of a unitary, one-piece structure. The lip 28,
however, does not have to be integrally formed as part of the table
top 12 and the table 10 does not require the lip 28.
[0053] As shown in the accompanying figures, the table top 12
preferably has a generally rectangular configuration with rounded
corners and slightly rounded edges 26. Desirably, the table top 12
has a relatively large size and it may be configured for use as a
banquet, conference or utility table. In particular, the table top
12 may have a length of about five feet (about 1.5 meters) and a
width of about two and one-half feet (about 0.75 meters). One of
ordinary skill in the art will appreciate that the table top 12 can
be larger or smaller according, for example, to the intended use of
the table 10. Additionally, the table top 12 may have other
suitable shapes and configurations such as square, circular, oval
and the like depending, for example, upon the intended use of the
table 10. In addition, the corners and edges 26 of the table top 12
do not have to be rounded and, in contrast, the corners and edges
could have any desirable configuration. Further, the table top 12
could be sized and configured for use with other types of tables
such as card tables, personal-sized tables, and the like.
[0054] The table top 12 is preferably constructed from a
lightweight material and, more preferably, the table top is
constructed from plastic, such as high density polyethylene. The
plastic table top 12 is desirably formed by a blow-molding process
because, for example, it may allow a strong, lightweight, rigid and
sturdy table top to be quickly and easily manufactured.
Advantageously, the blow-molded plastic table top 12 may be
lightweight because it may include a hollow interior portion that
is formed during the blow-molding process. It will be appreciated,
however, that the table top 12 does not have to be formed with a
hollow interior portion and the hollow interior portion can be
filled, for example, with a material such as foam after the table
top is formed.
[0055] The table top 12 is preferably constructed from blow-molded
plastic because blow-molded plastic table tops are relatively
durable, weather resistant, temperature insensitive, corrosion
resistant, rust resistant and blow-molded plastic generally does
not deteriorate over time. One of ordinary skill in the art,
however, will appreciate that the table top 12 does not have to be
constructed from blow-molded plastic and other suitable materials
can be used to construct the table top such as other types of
plastics, polymers and synthetic materials. In addition, the table
top 12 may be constructed from other materials with desirable
characteristics such as wood, metal, fiberglass, ceramics, graphite
and the like. Further, other types of processes may be used to
construct the table top 12 such as injection molding, rotary
molding and the like.
[0056] The upper surface 14 of the table top 12 is preferably
generally spaced apart from the lower surface 16 by a given
distance and these two spaced apart surfaces may help create a
rigid and strong table top. Preferably, the upper surface 14 and
the lower surface 16 of the table top 12 are separated by a
generally constant distance so that the surfaces are generally
aligned in parallel planes. The upper surface 14 and the lower
surface 16, however, do not have to be spaced apart by a generally
constant distance and, in fact, the upper and lower surfaces could
be separated by any desired distance.
[0057] The table top 12 may also include one or more structures or
features that may be sized and configured, for example, to increase
the strength and rigidity of the table top. In particular, the
table top 12 may include one or more depressions 30, which are also
known as tack-offs or kiss-offs, that are sized and configured to
increase the strength and rigidity of the table top.
Advantageously, the depressions 30 and/or other reinforcement
structures may be integrally formed as part of a unitary one-piece
table top 12, such as during the blow-molding or other molding
processes, but the depressions and other structures can also be
formed independently and/or attached separately of the table
top.
[0058] As shown in FIG. 2, the depressions 30 are preferably
located in the lower surface 16 of table top 12 and the depressions
are preferably sized and configured to increase the strength and
structural integrity of the table top 12. The depressions 30
preferably extend towards the upper surface 14 of the table top 12
and the ends of the depressions 30 may contact or engage the inner
portion of the upper surface of the table top. On the other hand,
the ends of the depressions 30 may be spaced part from the inner
portion of the upper surface 14 of the table top 12.
[0059] The depressions 30 preferably cover substantially the entire
lower surface 16 of the table top 12, but it will be appreciated
that the depressions may cover only a portion of the table top.
Additionally, while the depressions 30 are shown and described as
being located in the lower surface 16 of the table top 12, it will
be appreciated that the depressions could be formed in any desired
portion of the table top. For example, it will be appreciated that
one or more depressions 30 may be formed in the upper surface 14 of
the table top 12 and one or more depressions may be formed in the
lower surface 16 of the table top 12, and these opposing
depressions may be generally aligned. At least a portion of these
opposing depressions 30 may contact or engage each other, but the
opposing depressions do not have to touch or engage.
[0060] The depressions 30 are preferably also arranged into a
predetermined pattern or array in order to increase the strength
and structural integrity of the table top 12. In particular, the
depressions 30 are preferably spaced closely together in a
predetermined pattern such that the distance between the
depressions is minimized. For example, minimizing the distance
between the depressions 30 formed in the lower surface 16 of the
table top 12 may diminish the unsupported areas of the upper
surface 14 of the table top, which may increase the smoothness of
the upper surface of the table top. In addition, minimizing the
distance between the depressions 30 may increase the structural
integrity and strength of the table top 12. Thus, the depressions
30 may be desirably closely spaced on the lower surface 16 of the
table top 12 such that the depressions are separated by a minimum
distance in order to create a table top with greater strength,
improved structural integrity and an upper surface 14 with
increased smoothness.
[0061] In addition, the depressions 30 are preferably arranged in a
predetermined pattern with a generally constant and uniform spacing
so that the table top 12 has generally uniform characteristics. In
particular, the depressions 30 are preferably arranged into a
generally uniform pattern across at least a majority of the lower
surface of the table top 12 so that the strength, structural
integrity and/or other characteristics of the table top are
generally uniform throughout the table top. Thus, the table top 12
has fewer, if any, weak or unsupported portions which may decrease
the strength and structural integrity of the table top. Thus, the
depressions 30 may be used to create a table top 12 with generally
uniform characteristics. It will be appreciated that the
depressions 30 may also have a non-uniform spacing depending, for
example, upon various features that are formed in the table top 12
or upon the intended use of the table 10. It may be desirable,
however, for these various features that are formed in the table
top 12 to be sized and configured such that they do not
significantly disturb or disrupt the generally uniform pattern of
depressions 30.
[0062] Advantageously, the increased structural integrity and
strength of the table top 12 may allow the outer wall thickness of
the table top to be decreased, which may allow the table top to be
constructed with less material. For example, if the table top 12 is
constructed from blow-molded plastic and the outer wall thickness
is reduced, then less plastic may be used to construct the table
top. Because less plastic may be used to construct the table top
12, that may allow the cost of the table 10 to be decreased. In
addition, the table top 12 may cool more quickly during the
manufacturing process because of the decreased outer wall
thickness. This may allow the table top 12 to be removed from the
manufacturing mold more quickly and it may allow the table top to
be removed at a higher temperature because the thinner outer wall
may dissipate heat more rapidly. Significantly, because the cycle
time required to construct the table top 12 may be decreased, the
manufacturing efficiency may be increased.
[0063] Additional details regarding the size, shape and
configuration of one or more depressions that may suitable for use
in connection with the table top 12 are disclosed in Assignee's
pending U.S. patent application Ser. No. 10/409,000, which was to
<<filed Apr. 8, 2003, entitled HIGH-STRENGTH, LIGHTWEIGHT
BLOW-MOLDED PLASTIC STRUCTURES, which is incorporated by reference
in its entirety. While the table top 12 preferably includes one or
more depressions, it will be appreciated that the table top does
not require any depressions or other reinforcing structures.
[0064] As discussed above and as shown in FIG. 2, the lip 28 is
preferably disposed about the outer periphery of the table top 12
and it is generally aligned with the outer edge 26. The lip 28 may
include an inner portion, and outer portion and a lower surface.
Preferably, the outer portion of the lip 28 is generally aligned
with the outer edge 26, but the lip could also be spaced inwardly
from the outer edge of the table top. The lip 28 may also include a
hollow interior and the lip may be integrally formed during the
blow-molding process as part of table top 12. It will be
appreciated, however, that the lip 28 does not have to be formed as
a unitary component of the table top 12 and the table top does not
require the lip.
[0065] The lower surface of the lip 28 is preferably sized and
configured to facilitate stacking of the table 10. For example, the
lower surface of the lip 28 may have a generally smooth, planar
configuration to facilitate stacking of the table 10. In addition,
the inner portion of the lip 28 may include a number of serrations,
notches, ribs, struts and the like that are sized and configured to
increase the strength, rigidity and/or flexibility of the lip 28.
In particular, the inner portion of the lip 28 may include a number
of notches, indentations, grooves or other inwardly extending
portions to form at least a portion of an uneven or saw-tooth type
surface. The inner portion of the lip 28 may also include a number
of bumps, humps, protrusions or other outwardly extending portions
to form at least a portion of an uneven or saw-tooth type surface.
The inner portion of the lip 28 may also contain a combination of
inwardly and outwardly portions to form at least a portion of the
uneven or saw-tooth type surface. Other suitable configurations of
the lip 28 and other portion of the table 12 are disclosed in
Assignee's pending U.S. patent application Ser. No. 10/409,273,
which was filed Apr. 8, 2003, entitled EDGE AND CORNER FOR A TABLE
TOP; and Assignee's pending U.S. patent application Ser. No.
11/051,933, which was filed on Feb. 4, 2005, entitled EDGE AND
CORNER FOR A STRUCTURE CONSTRUCTED FROM BLOW-MOLDED PLASTIC; each
of which are incorporated by references in their entirety.
[0066] It will also be understood that other features of the table
top 12 may also be integrally formed with table top 12 as part of a
unitary, one-piece structure. For example, various mounting
portions, receiving portions and the like may be integrally formed
as part of the table top 12. Because these features may be
integrally formed as part of the table top 12, that may expedite
the manufacturing process. These features, however, do not have to
be integrally formed in the table top 12 and they could be attached
to the table top by any suitable methods or devices.
[0067] As seen in FIG. 3, the table top 12 may include one or more
table top sections 32, such as a first table top section 32a and a
second table top section 32b. The table top sections 32a, 32b may
include outer edges 34a, 34b; inner edges 36a, 36b; and opposing
side edges 38a, 38b and 40a, 40b respectively. It will be
appreciated that the table top 12 can include any suitable number
of sections 32 and the table top 12 may also be constructed as a
single, one-piece structure. Advantageously, the first table top
section 32a and the second table top section 32b may be moved
between a folded position as shown in FIG. 4 and an unfolded
position as shown in FIG. 1. When the table top 12 is in the folded
position, the table 10 may be more easily transported and/or
stored.
[0068] The inner edges 36a, 36b of the table top sections 32a, 32b
preferably contact, abut and/or are positioned adjacent to each
other when the table top 12 is in the folded position.
Significantly, the inner edges 36a, 36b of the table top sections
32a, 32b may be sized and configured to increase the strength
and/or rigidity of the table top 12. In particular, the inner edges
36a, 36b of the table top sections 32a, 32b may include one or more
portions that overlap, interlock and/or engage to increase the
strength and/or rigidity of the table top 12. In greater detail,
the inner edges 36a, 36b may include corresponding inwardly and
outwardly extending portions that are sized and configured to
contact, interlock and/or engage with the table top 12 is in the
folded position. For example, as shown in FIG. 3, the inner edges
36a, 36b may each include an upper portion and a lower portion. The
upper portions of the inner edges 36a, 36b may include generally
planar surface that are sized and configured to abut and/or be
positioned adjacent to each other when the table top 12 is in the
unfolded position. The lower portions of the inner edges 36a, 36b
may include one or more receiving portions, such as grooves or
recesses, and one or more outwardly extending portions, such as
extensions or flanges. The outwardly extending portions are
preferably sized and configured to be at least partially received
in the receiving portions when the table is in the unfolded
position.
[0069] When the table 10 is being moved from the folded position to
the unfolded position, the outwardly extending portions may be
disposed in the receiving portions to, for example, interlock the
table top sections 32a, 32b. This interlocking of the table top
sections 32a, 32b may increase the strength and/or rigidity of the
portion of the table top 12 along the inner edges 36a, 36b.
Advantageously, this may help create a table top 12 with a smoother
upper surface 14 and it may help prevent unwanted bending of the
table top along the inner edges 36a, 36b. It will be appreciated
that the outwardly extending portions and the receiving portions
can have a variety of different sizes, shapes and configurations.
It will also be appreciated that the table top 12 does not require
outwardly extending portions and/or the receiving portions.
[0070] As best seen in FIG. 2, the table 10 may include a frame 42
and the frame may be sized and configured to increase the strength
and/or rigidity of the table top 12, but the frame is not required.
As discussed below, the frame 42 may also be used to attach the
legs to the table top 12. As shown in the accompanying figures, the
frame 42 may be connected to the lower surface 16 of the table top
12 and the frame may include two side rails 44a, 44b that are
disposed proximate the outer edges of the table top. The side rails
44a, 44b preferably extend along all or at least a substantial
portion of the length of the table top 12, but the side rails could
have any suitable length and configuration. For example, while the
side rails 44a, 44b are preferably disposed proximate the lip 28,
the side rails may be disposed in any suitable location. It will be
appreciated that while the frame 42 preferably includes side rails
44a, 44b, the frame could have other suitable configurations and
arrangements, and the table 10 does not require a frame.
[0071] The frame 42 is desirably constructed from metal, which may
easily be formed into the desired configuration by known
operations, such as stamping and bending, and the metal may be
coated or painted as desired. The frame 42 may be connected to the
table top 12 be one or more fasteners, such as bolts or screws. The
frame 42 may also be attached to the table top 12 without
mechanical fasteners, such as disclosed in Assignee's pending U.S.
patent application Ser. No. 10/409,259, which was filed on Apr. 8,
2003, entitled FRAME THAT CAN BE ATTACHED TO A TABLE TOP WITHOUT
MECHANICAL FASTENERS, which is incorporated by reference in its
entirety.
[0072] As best seen in FIG. 2, the side rails 44a, 44b of the frame
42 are preferably connected to the first and second table top
sections 32a, 32b of the table top 12. For example, the side rails
44a, 44a may include first portions 46a, 46b that are connected to
the first table top section 32a, and second portions 48a, 48b that
are connected to the second table top section 32b.
[0073] The first and second table top sections 32a, 32b are
preferably pivotally connected to allow the table top 12 to be
moved between the folded and unfolded positions. For example, one
or more hinge assemblies may be used to pivotally connect the first
and second table top sections 32a, 342b. In particular, as shown in
the accompanying drawings, a first hinge assembly 50a may be
connected to the first side rail 44a and a second hinge assembly
50b may be connected to the second side rail 44b. The hinge
assemblies 50a, 50b may include a first portion that is connected
to the first portions 46a, 46b of the side rails 44a, 44b and a
second portion that is connected to the second portions 48a, 48b of
the side rails. The hinge assemblies 50a, 50b may include a hinge
member, such as a pin, bolt, rod or the like, that allows the hinge
assemblies to pivot about an axis. The hinge assemblies 50a, 50b
are preferably connected to the side rails 44a, 44b by welding,
adhesives, mechanical fasteners and the like. It will be
appreciated that the hinge assemblies 50a, 50b can also be at least
partially integrally formed as part of the frame 42. In addition,
it will be appreciated that the hinge assemblies 50a, 50b can be
connected to any suitable portions of the table 10 and the hinge
assemblies can have any suitable arrangement and configuration that
allows the first and second table top sections 32a, 32 to be
selectively moved between the folded and unfolded positions.
[0074] The table 10 may include a handle 52 that may be sized and
configured to facilitate lifting and moving the table. For example,
as shown in FIG. 2, the handle 52 may be mounted to a portion of
the table top 12 and the handle may project between the edges of
the table top sections 32a, 32b when the table top is in the folded
position (as shown in FIG. 4). In this configuration, a single
individual can easily gasp the projecting handle 52 to carry the
table 10. The table 10 may also include a handle retention assembly
54 that may advantageously secure the handle 52 in a generally
fixed position. Desirably, the handle retention assembly 54 secures
the handle 52 in an out of the way location, such as to the lower
surface 16 of the table top, when the table 10 is in the unfolded
position. Other suitable configurations of the handle 52 and/or the
handle retention assembly 54 are disclosed in Assignee's pending
U.S. patent application Ser. No. ______, filed concurrently
herewith, entitled HANDLE FOR A PORTABLE TABLE (Attorney Docket No.
15499.593), which is incorporated by reference in its entirety.
[0075] The table 10 may also include a locking mechanism that is
sized and configured to lock the table in a desired position. For
example, the locking mechanism may be used to secure the table top
12 in the unfolded position. In particular, as shown in FIG. 2, the
locking mechanism may include a bolt 56 that is slidable or
otherwise movable relative to the table top 12. The bolt 56, when
the table top 12 is in the unfolded position, may be designed to
selectively lock the hinge assembly 50 and/or the table frame 42 in
a generally fixed position. Accordingly, the locking mechanism may
lock the table top 12 in a secure and stable position, and the
table 10 can be easily moved without the risk of the table 12
unintentionally folding. In greater detail, as shown in FIGS. 5A
and 5C, the bolt 56 may secure the side rail portions 46a, 48a in a
generally fixed position. On the other hand, as shown in FIG. 5B,
the bolt 56 may be moved to allow the side rail portions 46a, 48a
to be freely moved. Other suitable embodiments for the bolt 56
and/or the hinge assembly 50 are discussed in further detail
below.
[0076] As discussed above, the table 10 may include one or more
legs 58 and the legs are preferably movable between an extended or
use position and a collapsed or storage position relative to the
table top 12. Preferably, the legs 58 are positioned adjacent or
proximate the lower surface 16 of the table top 12 in the collapsed
or storage position to facilitate stacking, storage and/or shipping
of the table. In addition, the legs 58 are preferably positioned
adjacent or proximate the lower surface 16 of the table top 12 to
allow the table top 10 to be positioned in a folded position such
that the first table top section 32a is positioned adjacent or
proximate the second table top section 32b.
[0077] For example, as shown in FIG. 2, the table 10 may include
four legs 58a, 58b, 58c, 58d and one or more of the legs may be
interconnected. The legs 58a, 58b, 58c, 58d are preferably sized
and configured to support the table top 12 above a surface such as
a floor, and the legs may be adjustable in length. It will be
appreciated, however, that the legs 58 could be independently
connected to the table 10 and the legs do not have to be adjustable
in length. It will also be appreciated that the legs 58a, 58b, 58c,
58d may be connected to the table top 12 in any suitable manner.
For example, the legs 58a, 58b, 58c, 58d may be connected to
connecting rods 62 and the connecting rods may be connected to the
frame 42. In particular, the ends of the connecting rods 62 may be
disposed within openings in the side rails 44 of the frame 42 to
allow the legs 58a, 58b, 58c, 58d to be attached to the table top
12.
[0078] The connecting rods 62 and the legs 58 are desirably
constructed from hollow metal tubes because the metal tubes are
relatively lightweight and strong. The hollow metal tubes forming
the connecting rods 62 and legs 58 may have a generally oval
configuration to provide increased strength. Advantageously, the
oval configuration may also be used to create a thinner profile for
the legs 58, which may create a thinner profile for the table 10
when the legs 58 are in the collapsed position.
[0079] It will be appreciated that the legs 58 may be constructed
from other materials with the suitable characteristics and the legs
58 may have other shapes and configurations depending, for example,
upon the intended use of the table 10. For example, the legs 58 may
include only a single elongated support member or multiple
elongated support members, and the legs 58 may be constructed as a
single component or multiple components that are connected
together. It will further be appreciated that the legs 58 need not
be in pivotal engagement with frame 42 or the table top 12 to be
collapsible. For example, the legs 58 may be detachably connected
to the table top 12 such that when it is desired to collapse the
table 10 for storage, the legs 58 are detached from the table top
12. Other suitable arrangements and configurations for attaching
the legs 58 to the table 10 are disclosed in Assignee's pending
U.S. patent application Ser. No. 10/408,917, filed Apr. 8, 2003,
entitled PIVOTAL CONNECTION OF A TABLE LEG TO A FRAME, which is
incorporated by reference in its entirety.
[0080] As shown in FIGS. 1 and 2, one or more braces 60 may be used
in connection with the legs 58. For example, a brace 60a, 60b, 60c,
60d may be attached to the legs 58a, 58b, 58c, 58d, respectively,
and the braces may be used to secure the legs in the extended
position. The braces 60 may be a slotted brace in which a pin is
disposed within an elongated slot. The braces 60 may also include a
biasing member, such as a spacer or washer, which is preferably
constructed from a deformable and resilient material, such as
rubber, which may be used to bias the brace into a desired
position. For example, the biasing member may be used to bias the
brace 60 into a locked position, which may be used to lock the leg
58 in the extended position. Other suitable types of braces and
mechanisms that may be used in connection with the table 10 are
disclosed in Assignee's pending U.S. patent application Ser. No.
______, filed concurrently herewith, entitled BRACE ASSEMBLY FOR A
TABLE (Attorney Docket No. 15499.611), which is incorporated by
reference in its entirety.
[0081] As shown in FIG. 2, the table 10 may include a retainer 64
that may be sized and configured to secure the table in the folded
position. For example, as shown in the accompanying figures, the
retainer 64 may be connected to a first portion of the table 10,
such as the first table top section 32a. In particular, the
retainer 64 may be connected to a portion of the frame 42, such as
the connecting rod 62b. The retainer 64 is preferably sized and
configured to be connected to a second portion of the table 10,
such as the second table top section 32b, when the table is in the
folded position. In greater detail, the retainer 64 is preferably
sized and configured to be connected to a portion of the frame 42,
such as the connecting rod 62a, when the table top 12 is in the
folded position.
[0082] Advantageously, the retainer 64 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 64 may be sized and configured to
automatically engage the other portion of the table top 12 to
simplify the engagement process. The retainer 64 may also be
quickly and easily connected to the connecting rods 62a and/or 62b,
which may simplify the manufacturing process and allow the retainer
to be used in a wide variety of situations and environments.
Additionally, the retainer 64 may be connected to suitable portions
of the table top 12 to secure the retainer in a fixed position.
Significantly, because the retainer 64 may be connected to the
table top 12 and/or the connecting rods 62a, 62b 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 64 may be connected to the table 10 by
mechanical fasteners, adhesives, and the like, and the retainer can
be attached to any suitable portions of the table.
[0083] Desirably, one portion of the retainer 64 is securely
connected to a first portion of the table top 12, such as the
connecting rod 62b, so that the retainer is permanently connected
or not easily removed from that portion of the table top. The other
portion of the retainer 64 is preferably selectively connected to
another portion of the table top 12, such as the connecting rod
62a, so that the retainer may be quickly and easily attached and
detached. This may allow the retainer 64 to quickly and easily
secure the table top 12 in the folded position, and allow the table
top to be quickly and easily moved into the unfolded position. It
will be appreciated that either or both portions of the retainer 64
may be selectively or permanently connected to suitable portions of
the table top 12 depending, for example, upon the design and/or
intended use of the table 10. Other suitable embodiments for the
retainer 64 are disclosed in Assignee's pending U.S. patent
application Ser. No. ______, filed concurrently herewith, entitled
RETAINER FOR SECURING A TABLE IN A FOLDED POSITION (Attorney Docket
No. 15499.589), which is incorporated by reference in its
entirety.
[0084] As mentioned above, the table 10 may include a locking
mechanism, such as a bolt 56, which is movable between a locked
position and an unlocked position. In particular, when the table
top 12 is in the unfolded position, the bolt 56 may be designed to
selectively lock, in a generally fixed position, the hinge assembly
50 and/or the first and second table top sections 32a, 32b. As
shown in the accompanying figures, the bolt 56 may be slide from a
first position shown in FIG. 5A, in which the rail portions 46a,
48a are in a generally fixed position, to a second position shown
in FIG. 5B, which the rail portions may be freely moved.
[0085] As shown in FIGS. 5A and 5B, the rail portions 46a, 48a may
be pivotally by one or more hinge assemblies 50. The hinge
assemblies 50 may include a first bracket 66a and a second bracket
66b in which the bracket 66a may be connected to or formed
integrally with the rail portion 46a and the bracket 66b may be
connected to or formed integrally with the rail portion 48a. The
brackets 66a, 66b may respectively include one or more wall
portions or flanges 68a, 68b and the flanges may include an
aperture that is sized and configured to receive a pivot pin 70 to
facilitate the pivotal attachment of the brackets 66a, 66b. The
pivot pin 70 may consist of a rivet with flared ends to retain the
rivet in a desired position. It will be appreciated that the pivot
pin 70 may also be other suitable structures such as a bolt, rod,
fastener and the like. It will also be appreciated that the pivot
pin 70 and the brackets 66 may have a variety of suitable shapes
and/or configurations.
[0086] As shown in FIGS. 5A, 5B, and 5C, the bolt-56 may be at
least partially disposed within bolt receiving sections. For
example, when in an unlocked position as shown in FIG. 5B, all or
at least a portion of the bolt 56 is preferably disposed within a
first section that is entirely or at least partially defined by the
rail portion 48a. When in a locked position as shown in FIGS. 5A
and 5C, at least a portion of the bolt 56 is preferably disposed
within the first section and at least a portion of the bolt 56 is
preferably disposed entirely or at least partially within a second
section defined by the rail portion 46a.
[0087] The bolt 56 may be at least partially disposed within bolt
receiving sections that are at least partially defined by a portion
of the table frame 42 and at least partially defined by at least a
portion of the table top 12. For example, a first section may be at
least partially defined by the rail portion 46a and at least
partially defined by the table top section 32a, and a second
section may be at least partially defined by the rail portion 48a
and at least partially defined by the table top section 32b. In a
further example, the rail portions 46a, 48a may have a generally
U-shaped cross section, and the rail portions may be connected to
the table top 12 using a snap fit, a friction fit, an interference
fit, mechanical fasteners, adhesives, and/or any suitable
combination thereof. When the generally U-shaped rail portions are
connected to the table top 12, this may advantageously form
sections within which portions of the bolt 56 may be disposed in
locked and unlocked positions. It will be appreciated that the rail
portions 46a, 48a may have other suitable shapes and
configurations. Advantageously, constructing the bolt receiving
sections that are at least partially defined by a portion of the
table top 12 and/or portion of the table frame 42 may help to
simplify manufacturing, which may save time and costs. This may
also allow bolts 56 with various sizes, shapes and configurations
to be used. It will be appreciated, however, that the bolt
receiving sections may be formed by any suitable portions of the
table 10.
[0088] As shown in FIGS. 5A to 5D, the bolt 56 may include an
elongated body 72 with a first end 74, a second end 76 and a handle
78 that is preferably disposed proximate the second end 76. The
handle 78 may be sized and configured to extend through and slide
along a slot 80 formed in the rail portion 48a. Accordingly, a user
may grip the handle 78 to slide or otherwise move the bolt 56 among
a variety of positions, including a locked position and an unlocked
position.
[0089] As best seen in FIG. 5D, the slot 80 includes a first end
82, a second end 84 and a pair of opposing sides 86, 88 that extend
between the first and second end of the slot. The slot 80
preferably includes locking apertures 90a, 90b and the locking
apertures may be respectively disposed proximate the opposing ends
82, 84 of the slot. As shown in FIGS. 5C and 5D, the locking
apertures 90a, 90b may be preferably sized and configured to
releasably receive at least a portion of the bolt 56, such as the
handle 78. The locking apertures 90a, 90b may also be sized and
configured to secure the bolt 56 in a fixed position, such as by
using a snap fit, a friction fit, an interference fit or the like.
In greater detail, the locking apertures 90a, 90b have a generally
circular shape including curvilinear recessed portions 94a, 94b.
The recessed portions 94a, 94b may include, without limitation,
recesses, apertures, grooves, indentations, and the like. The
recessed portions 94a, 94b are preferably offset from the elongated
sides 86, 88 of the slot. Advantageously, the bolt 56 may be biased
to be received and retained within the locking apertures 90a,
90b.
[0090] Accordingly, the locking apertures 90a, 90b may be used to
help secure the bolt 56 in a variety of positions, including an
extended, locked position and a retracted, unlocked position. For
example, to selectively lock the table top 12 in the unfolded
position, a user may move the bolt 56 to the extended position in
which the locking aperture 90a engages the handle 78. To
selectively unlock the table top 12 from the unfolded position, the
user may move the bolt 56 to a retracted position in which the
locking aperture 90b engages the handle 78.
[0091] It will be appreciated that the slot 80 need not include the
locking apertures 90a, 90b; and that the slot 80, the apertures 90,
the aperture 92, and the recessed portions 94 may have a variety of
suitable shapes and configurations, depending, for example, upon
the particular shape and configuration of the bolt 56. It will also
be appreciated that the bolt 56 may have a variety of suitable
shapes and configurations. In addition, although the bolt 56 and
slot 80 are illustrated with reference to the hinge assembly 50a, a
bolt could also be provided to couple with a slot formed in one of
the rail portions 46b, 48b to selectively lock and/or unlock the
hinge assembly 50b. Thus, a bolt and/or slot may be provided with
some or all of the hinge assemblies 50 of the table 10, if
desired.
[0092] The bolt 56 is preferably constructed of a strong, rigid
material such as metal. In particular, the bolt 56 may be
constructed from steel, aluminum or other metals with suitable
characteristics. The bolt 56, however, could also be constructed
from other materials with appropriate characteristics such as
plastics, composites and the like. The bolt 56 may also have a
unitary, one-piece construction or the bolt may be constructed from
a plurality of interconnected components.
[0093] An exemplary embodiment of a bolt that may be used with the
locking member is shown in FIG. 6. The bolt 96 includes a body 98
with a first end 100 and a second end 102. The body 98 of the bolt
96 may also include a head 104, a handle 108, a neck 110 and a
locking portion 112. For example, to selectively lock the table top
12, all or at least a portion of the locking portion 112 of the
bolt 96 may be received into one or more bolt receiving sections,
as described above.
[0094] The handle 108 may include two portions that are
interconnected. For example, the handle 108 may include a first
portion 106 and a second portion 108 and these portions may include
one or more alignment members. In particular, the alignment member
114 of the first portion 106 may be sized and configured engage the
alignment member 116 of the second portion 108. For instance, the
alignment member 114 of the first portion 106 may consist of an
outwardly extending, portion having a generally angled, V-shaped
configuration and the alignment member 116 of the second portion
108 may consist of an inwardly extending portion having a generally
angled, V-shaped configuration. Advantageously, the alignment
members may be used to hold the handle portions 106, 108 in a
generally fixed position, which may facilitate the attachment of
the handle portions. A mechanical fastener, such as a screw 118,
may be used to connection the handle portions 106, 108 by inserting
it through the openings 120, 122. It will be appreciated that the
handle portions 106, 108 could have other suitable arrangements and
configurations, and the alignment members are not required. It will
also be appreciated that a handle need not be formed into separate
portions and the handle may be integrally formed as part of the
bolt 96. However, the separate portions or the handle may
facilitate the assembly of the table 10--especially where the
handle might be awkward and time consuming to install.
[0095] As shown in FIGS. 6-10, the locking portion 112 of the bolt
96 may include one or more elongated channels that extend along all
or at least a portion of the length of the locking portion. For
example, the locking portion 112 may include an angled, generally
V-shaped channel 124 on a first side and an angled, generally
V-shaped channel 126 on a second side. Advantageously, the channels
may be sized and configured to align the bolt 96 in a desired
position and to help facilitate installation of the bolt. Further,
the channels 124, 126 may help the bolt 96 to be manufactured more
quickly. It will be appreciated that the channels 124, 126 may have
other suitable shapes and configurations, and that the locking
portion 112 may not require any such channels.
[0096] As shown in FIGS. 6-10, the locking portion 112 of the bolt
96 may also include one or more tapered portions 128, 130, which
are preferably disposed proximate the ends of the locking portion.
The tapered portion 128 may advantageously be used to guide the
bolt 96 into an extended, locked position. The tapered portions 130
may advantageously be used to guide the bolt 96 into a retracted,
unlocked position and/or to facilitate installation of the bolt
during assembly of the table 10.
[0097] Another exemplary embodiment of a bolt that may be used with
the locking member is shown in FIG. 15. The bolt 132 includes a
body 134 with a first end 136 and a second end 138. The body 134
may include a head 140, which may form a portion of a handle 142, a
neck 144 and a locking portion 146. For example, to selectively
lock the table top 12 in the unfolded position, all or at least a
portion of the locking portion 146 of the bolt 132 may be received
into one or more locking sections, as described above.
[0098] As shown in FIGS. 15 and 16, the handle 142 may include an
aperture 148 and the aperture may be sized and configured to
receive a fastener, such as a screw. This may be used to connect
another part to the handle 142, such as an extension or grip. As
discussed above, the handle 142 may be integrally formed as part of
the bolt 132 or it may be a separate component that is attached to
the bolt.
[0099] As shown in FIGS. 15-18, the locking portion 146 may include
elongated arms 150a, 150b. The arms 150a, 150b are preferably
constructed of a deformable, resilient material, such as plastic,
but other suitable materials may also be used. The arms 150a, 150b
respectively include catches 152a, 152b, and the arms are
preferably spaced apart by a notch 154. The notch 154 preferably
has an elongated, tapered shape that tapers toward a rounded end
portion 156. The notch 154 may be sized and configured to increase
the flexibility, rigidity, and/or strength of the arms 150a,
150b.
[0100] The arms 150a, 150b of the bolt 132 may advantageously be
used to secure the bolt 132 in a variety of positions, including an
extended, locked position and a retracted, unlocked position. For
example, to selectively lock the table top 12 in the unfolded
position, the user may move the bolt 132 to the extended position
in which the arms 150a, 150b engages at least a portion of a bolt
receiving sections. As mentioned above, such bolt receiving
sections may, for example, be at least partially defined by at
least a portion of the table top 12 and/or at least partially
defined by a portion of the table frame 42. To selectively unlock
the table top 12 from the unfolded position, the user may move the
bolt 132 to a retracted position in which the arms 150a, 150b no
longer engage at least a portion of a bolt receiving section.
Preferably, as the arms 150a, 150b of the bolt 132 are received
into the bolt receiving section, the walls of the socket may deform
the arms to allow the catches 152a, 152b of the arms to resiliently
engage the bolt receiving section. The bolt receiving sections may
also include one or more catch receiving portions that are sized
and configured to receive and retain the catches 152a, 152b in a
fixed position. Advantageously, as the arms 150a, 150b of the bolt
132 are removed from the socket, the arms may resilient return to
their initial configuration.
[0101] As shown in FIGS. 15-18, the bolt 132 may include a guide
portion 158, which is preferably sized and configured to correctly
position the bolt within the bolt receiving sections. For example,
the guide portion 158 may space the end portion 136 of the bolt 132
away from the walls of the section, such as a wall of a rail
portion or the lower surface of the table top 12. Accordingly, as
best seen in FIG. 18, the guide portion 158 may provide a contact
surface. As shown in the accompanying figures, the guide portion
158 may have a generally circular, curvilinear configuration, which
may provide less friction and may assist in correctly positioning
the bolt 132. It will be appreciated, however, the guide portion
158 may have other suitable shapes and configurations.
[0102] As shown in FIGS. 15-17, the locking portion 146 of the body
134 of the bolt 132 may include a tapered portion 160, which may be
spaced apart from the end portions 136, 138. The tapered portion
160 is preferably defined by a pair of opposing generally
curvilinear, concave surfaces 162a, 162b; but the tapered portion
160 and the surfaces 162 may have other suitable shapes and
configurations. Advantageously, the tapered portion 160 may be
sized and configured to increase the flexibility, rigidity, and/or
strength of the bolt 132. It will be appreciated that the tapered
portion 160 may have other suitable shapes, sizes and
configurations, and that the tapered portion is not required.
[0103] 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.
