Description
BACKGROUND
[0001] The present disclosure relates generally to a communication
system used for two-way audio transmission. More particularly, the
present disclosure relates to audio communication systems for use
in conducting meetings, teleconferences, and the like.
[0002] Generally, conference tables are used concurrently by
multiple persons as a gathering place for information exchange. The
tables are typically designed to support writing pads and utensils
necessary to facilitate the exchange of information and, in most
cases, are designed to support electronic devices to communicate
information more efficiently. These electronic devices may include,
for example, telephones, computers, monitors, speakers and various
audio devices, word processors and play-back devices, as well as
the wirings and connectors associated therewith.
[0003] Because modern business meetings typically require the use
of several different modes of electronic communication, meetings
where multiple electronic devices are required can be problematic
because the devices and wirings occupy a large portion of the
table. Consequently, available work space for meeting participants
is reduced and, therefore, overall meeting efficiency is
reduced.
[0004] Moreover, the presence of multiple electronic devices
including the wirings and connectors associated therewith, can
detract from the overall aesthetic appearance of a workspace. More
specifically, increased amounts of clutter on conference tables
during meetings can not only decrease communication efficiency but
can also create a less aesthetically pleasing environment, which
detracts from the efficiency of the meeting.

DETAILED DESCRIPTION
[0031] The present disclosure relates to tables, communication
systems that are intended to be incorporated within a tabletop, and
methods for conducting business meetings. As used in the present
description, the expression "tabletop" means any surface that is
elevated and designed to afford an individual the ability to
utilize the surface for work, eating, or similar activities,
including surfaces defined by tables, desks, end tables, coffee
tables, or conference tables. For example, the tabletop could
include a large conference table that is 40-60 feet in length and
has a plurality of communications systems embedded within or
mounted to the tabletop, thereby providing a conference table
wherein a number of people may be seated about the periphery of the
table, and have a separate communication system available for their
use.
[0032] As illustrated in FIG. 1, an embodiment of a table is
generally designated by the numeral 10. The table 10 includes at
least one supporting member 12 and a tabletop 14 having a
horizontal surface 16 and at least one opening 18. The supporting
member 12 in the illustrated embodiment comprises two table legs.
However, it should be appreciated that any number of table legs or
other suitable supporting structures may be used that provide for
an elevated tabletop 14.
[0033] The table 10 includes one opening 18 that is configured to
accommodate a two-way communication system 20. In addition, the
table may include one or more additional electronic or peripheral
devices 22 that may or may not be connected to the separate audio
amplification systems 20. In one example, the peripheral device 22
may be an audio amplification device or microphone or other
communication apparatus. In FIG. 1, the opening 18 is illustrated
to be of a substantially square cross-sectional configuration.
However, while the opening 18 is shown in a substantially square
cross-sectional configuration, it should be appreciated that other
geometric shapes are possible that allow for a pivoting motion of a
two-way communication system 20 embedded in the surface 16 of the
table 10. For example, the opening 18 may be substantially ovular,
circular, rectangular, or any other suitable geometric shape. In an
embodiment, the shape of the opening 18 should be symmetrical to
allow for a 180 degree pivot between a working position and a
storage position. More generally, the opening 18 should be a shape
that corresponds to a shape of a working surface and a shape of the
storage surface, such that when the two-way communication system 20
is pivoted from one position to another, the working surface and
the storage surface substantially fit within the opening 18.
[0034] As illustrated in FIG. 2, the two-way communication system
20 is in the storage or closed position. Therefore, the two-way
communication apparatus 26 is hidden or located under the surface
16 of the tabletop 14. In this position, a surface 78 of the
two-way communication system 20 is substantially parallel and
co-planar with the surface of the tabletop 14 to allow for
increased workspace to the user or users. In an embodiment, the
surface is also aesthetically pleasing and may also have a surface
characteristic similar to the surface of the tabletop. As shown in
FIG. 1, the two-way communication system 20 is in the working or
open position. Thus, the two way communication apparatus 26 or
telephone is available for use and it extends from the surface 16
of the tabletop 14.
[0035] Although the table 10 in FIG. 1 is illustrated to
accommodate a single two way communication system, it should be
appreciated that the table 10 may include any suitable number of
systems. In an embodiment, as shown in FIG. 1, the two-way
communication system 20 is shown to be embedded within the opening
18 of tabletop 14. The two-way communication system 20 includes at
least one member or frame 50 (see, FIG. 5) that is mountable to a
portion of a tabletop 14 corresponding to the opening 18. The
two-way communication system also includes a support 70 pivotally
connected to the frame 50.
[0036] In an embodiment, as illustrated in FIG. 4, the support 70
is a square shaped planar member composed of an first member 100
and a second member 104. However, it should be appreciated that in
other embodiments, the support may include any suitable number of
pieces. For example, in another embodiment, the support may be a
single piece with one or more channels bored into the interior such
that one or more pathways are formed that allow one or more wirings
to be routed from the two-way communication apparatus through the
interior of the support.
[0037] In one embodiment, as illustrated in FIG. 3, the support 70
includes a first member 100 having a surface 78 that is exposed or
viewable when the two way communication system is pivoted into the
storage or closed position. The support 70 also includes a second
member 104 having a surface 76 that is exposed or viewable when the
two-way communication system is in the open or working position. In
an embodiment, a circular bore 90 is formed through the second
member 104. In addition, a circular recess 92a is formed at least
partially into the second member 104 from an interior side of the
second member 104. Likewise, a circular recess 92b is formed into
the interior surface of the first member 100. Grooves or channels
94a and 94b are formed into the interior portions of the first
member 100 and second member 104. In one embodiment, these channels
94a and 94b are formed from the center of the first and second
members to the periphery of the members. Thus, when the first
member 100 and second member 104 are attached to each other by, for
example screws 97 and brackets 98, as illustrated in FIG. 4, a
suitable channel 96 is formed. Thus a suitable pathway is formed
from the surface 76 of the second member 104 to the sidewalls 94 of
the support 70. Accordingly, one or more wirings 68 from the
two-way communication apparatus 26, such a power cord, can be
routed from the audio amplification apparatus 26, through the
opening 90, through the channel 96 and out the sides 94 of the
fully assembled support 70. In this fashion, the wires are not
visible to a user and are still capable of being routed to the
appropriate power source or data line.
[0038] In one embodiment, as illustrated in FIG. 3, the first and
second members 100, 104 of the support further include a plurality
of channels 99 formed into the interior surfaces of the members.
When the first and second member are attached, the channels 99 form
a plurality of cylindrical bores that each accommodate a bearing
such as a split bearing 56 (see also, FIG. 4).
[0039] The support 70 may also include one or more grooves 73
formed into the sidewall 94. In one example, as best illustrated in
FIG. 2, a slight chamfer is applied to the interior edges of first
member 100 and second member 104, such that when they are attached
together the edges form the groove 73, as shown in FIG. 4. This
groove or grooves 73 mate with the spring loaded detent 51 (see,
FIG. 5) when the support is rotated into one of the storage
position or the working position. The detent 51 thus restricts
pivotal motion of the support to a certain extent.
[0040] In an embodiment, as shown in FIG. 5, the frame 50 is a
square frame having four sides 64 and mounted to four edges of the
tabletop as defined by the opening 18 in the tabletop 14. The four
sides of the frame may be separate pieces that are screwed together
at the ends to form the four sided frame. In another embodiment,
the frame is formed from a single piece. Although the frame 50 is
illustrated in FIG. 5 to be square, it should be appreciated that
the frame 50 may be any suitable shape and generally corresponds to
the shape of the opening 18. For example, if the opening is
circular, the frame would also be circular. In an embodiment, the
circular frame is a single piece.
[0041] In an embodiment, the frame 50 is attached to the tabletop
14 using fastening means 97 (as shown in FIG. 6) including, but not
limited to, screws, nails, nuts or bolts. For example, FIG. 5 shows
a frame 50 having a plurality of openings 54 that can accommodate a
bolt or screw or other suitable fastener. The frame 50 may be
removable from the tabletop 14 or integral with the tabletop
14.
[0042] As shown in FIG. 5, the frame 50 includes two openings 62.
In an embodiment, each of the openings 62 are circular and
accommodate a split bearing 56. The split bearings 56 are rotatable
within the openings 62. Moreover, both of the split bearings 56 are
rotatable about a common central pivotal axis 58. The bearings 56
function, at least in part, to pivotally support the main support
70 of the communication system 20, as described in further detail
below.
[0043] As shown in FIG. 6, in an embodiment, the split bearings 56
comprise an interior bore 66. One or more wirings 68 from the
two-way communication apparatus 26 are routed through the interior
bore 66 of the split bearing 56. It should be appreciated that it
is not required that the bearings are split bearings. For example,
the bearings may be a single piece bearing having an interior bore.
In another embodiment, the wires from the telephone are guided
through the split bearing 56 and are also secured or fixed to the
split bearing 56. In another embodiment, the wirings 68 are not fed
through an interior bore of a bearing and are simply fed through
another opening (not shown) in the frame 50.
[0044] As best illustrated in FIGS. 6 and 7, the support 70 is
pivotally attached to the frame 50 at two pivot points
corresponding the location of the split bearings 56. In an
embodiment, the bearings 56 are at least partially inserted into
circular recesses formed by the combination of channels 99 (see
also, FIG. 3) formed into the sides of the support 70. Therefore,
the bearings 56 provide support for the support 70 and allow the
support 70 to pivot about the central pivotal axis 58, where the
central pivotal axis 58 is substantially horizontal and parallel to
the surface 16 of the tabletop 14. In one embodiment, the central
pivotal axis 58 is also located slightly below the surface 16 of
the tabletop 14 by a distance generally corresponding to half of
the thickness of the support 70. That is, when the support 70 is
pivoted to the working position, the surface 76 is substantially
parallel with the surface 16 of the tabletop 14. Similarly, it is
desired that when the support 70 is pivoted to the storage or
closed position, that the surface 78 is substantially parallel with
the surface 16 of the tabletop. Accordingly, the surface 78 is
exposed when the communication apparatus 20 is in the storage
position or closed position and the surface 76 is exposed when the
support is pivoted 180 degrees into the working or open or
operating position.
[0045] In an embodiment, the telephone or other suitable two-way
communication apparatus 26 is mounted to the surface 76 of the
support 70 such that the two-way communication apparatus is hidden
when in the storage position (see, FIG. 2) and is available for use
when pivoted to the operating position (see, FIG. 1). In an
embodiment, the two-way communication apparatus 26 includes a
telephone having a dialing input, one or more speakers and a
microphone. The two-way communication apparatus 26 is appropriately
sized to fit on the surface 76 of the support 70.
[0046] In an embodiment, as shown in FIG. 5, the frame 50 includes
one or more detents 51 for securing the support 70 in either the
working position or the storage position. In one example, a spring
loaded detent 51 is screwed into a wall 64 of the frame 50.
Corresponding recesses or notches 73 are formed into the sidewall
of the support 70 (see, FIG. 4). Therefore, when the support 70 is
pivoted about the central pivoting axis 58 into the storage or
closed position, the detent 51 mates with the channel 73 to
maintain the support 70 in a relatively stable pivotal position.
Similarly, when the support 70 is pivoted about the central
pivoting axis 58 into the working or open position, the detent 51
mates with a different channel formed in the support 70 to maintain
the support 70 in a relatively stable pivotal position.
[0047] In one embodiment, the user can release the support 70 from
the locked position by tapping, depressing or otherwise releasing
the detent 51. After the support 70 has been released, the user can
then pivot the support 70 into either the working position or the
storage position. These embodiments allow the support 70 to remain
in a stable position and also facilitate the user in pivoting the
support 70 from one position to another. In other embodiments, the
communication system 20 includes a drive or motor (not shown) that
causes the support 70 to pivot to a different position after the
user has released the support from a starting position.
[0048] In an embodiment, as shown in FIG. 5, the frame 50 is a
square frame having four sides, the frame being mounted to the
tabletop as described above. In this embodiment, two of the sides
include recessed portions 60a, 60b on an interior side of the frame
50. As shown in FIG. 5, the recesses are formed only part of the
way through the frame in the vertical direction. A first one of the
recessed portions 60a accommodates a pin 72 or other suitable
protrusion extending from the support 70 and functions as a hard
stop when the support 70 is pivoted into the working position. A
second one of the recessed portions 60b accommodates the same pin
72 or another pin and functions as a hard stop when the plate is
pivoted into the storage position. That is, the hard stops function
to obstruct the support 70 from pivoting beyond a maximum pivotal
range of about 180 degrees. This reduces the amount of twisting of
the wires, where the wires are routed from the two-way
communication apparatus and through the interior bore 66 of the
split bearing 56.
[0049] In an embodiment, the opening in the tabletop 14 is a
rectangular opening sized to accommodate the communication system
20. The rectangular opening defines four walls or mounting surfaces
(not shown) that a have a thickness corresponding to the thickness
of the tabletop. These four walls include threaded openings for
mounting the frame 50. More specifically, the sidewalls 64 of the
square frame 50 of the support include several openings 54
corresponding to the openings in the four mounting surfaces in the
tabletop. Any suitable attaching means such as screws, pins,
dowels, or bolts are fed through the holes 54 in order to mount the
frame 50 to the tabletop 14. Therefore, the frame 50 is
side-mounted to the walls of the tabletop. It should be appreciated
that where the opening in the tabletop 14 is circular or ovular or
any suitable shape that the frame is a corresponding shape and
would similarly include holes for side-mounting the frame to the
tabletop 14. In one embodiment, the holes 54 of the frame 50 are
countersunk and accept a screw with a tapered head. In this
embodiment, the screws are substantially flush with or slightly
recessed from the inside surfaces of the sidewalls 64 of the frame
50. This allows the support 70 to freely pivot within the frame 50
without interfering with the mounting bolts or screws.
[0050] In an embodiment, as illustrated in FIG. 4, the support 70
includes an interior portion such as a channel 96 for housing
and/or guiding one or more wires 68 leading from the two-way
communication apparatus 26 or telephone to an interior or underside
of the tabletop 14. In an embodiment, the support 70 is a split
platform that includes two sections that define an interior channel
96, as illustrated in FIG. 4. The wires include one or more of the
following: a telephone wire; a power cord; and a network cable such
as an Ethernet wire. The wires 68 are guided from the bottom of the
two-way communication apparatus 26 or telephone, into the interior
of the support 70 through an opening 90 in the surface 76 of the
support 70, as illustrated in FIG. 3. As shown in FIG. 6, the wires
68 are then guided through the interior bore 66 of the split
bearing 56, thereby also passing through the opening 62 in the
frame 50. The wires 68 continue to be routed under the tabletop 14
for connection to a power source or a data communication jack.
[0051] Although the support 70 has been described above as
including two main components or members, it should be appreciated
that the support 70 may be a single piece or may include three or
more components, such that the wires 68 from the two-way
communication apparatus 26 can be suitably routed therein.
[0052] As illustrated in FIG. 7, the support 70 and frame 50 are
shown where the support is pivoted partway between the storage
position and the working position. The channels 60a, 60b formed
into the frame 50 function as a hard stop that restrict the support
70 from being pivoted beyond a pivotal range of approximately 180
degrees. Thus, the stress on the wirings 68 from twisting is
reduced.
[0053] In an embodiment, the support 70 includes at least one
melanine based substrate having a surface coating or layer 76 or
veneer applied thereto. In one embodiment, the surface layer 76
includes a composite veneer. In this example, the surface 76 is
attached or affixed or adhered to the melanine based substrate. Any
suitable adhesive, glue or other suitable affixing medium may be
used. It should be appreciated that the substrate of the top member
100 may comprise any suitable materials such as polymer based
materials, resins, wood, ceramics or the like. In an example, the
surface 76 has an artificial wood grain appearance. In further
examples, the surface 76 may be marble, faux leather, wood or any
other suitable surface material. As mentioned above, the one-way
audio amplification apparatus 26 or microphone is fixed or mounted
to the surface 76 of the support 70, such that the audio
amplification apparatus 26 extends above the surface 16 of the
tabletop 14 for use.
[0054] The other surface 78 of the support 70 includes a table
coating having a composite veneer. In this example, the surface 78
is attached or affixed or adhered to the melanine based substrate
as well. Any suitable adhesive, glue or other suitable affixing
medium may be used. It should be appreciated that the surface 78
may be marble, faux leather, wood or any other suitable surface
material, as described above with reference to the surface 76.
Alternatively, the surface 78 can include other suitable materials
having appropriate cosmetic or tactile appeal to the users.
[0055] In an embodiment, the communication system 20 includes a
switch or switching device (not shown) that activates the power
such that when a user pivots the support 70 from the storage
position to the working or open position the audio amplification
system powers on. In one example, when the support 70 is pivoted
into the working position, the support 70 completes an electrical
circuit to cause the communication system 20 to turn on or power
up. Similarly, when the support 70 is pivoted away from the working
position, the electrical circuit is broken and the communication
system 20 is powered down. The switching device may be a mercury
switch, a roller ball or any other suitable electrical switching
device that operates, at least in part, based on gravity. In other
embodiments, the communication system 20 may be powered on even
when the support 70 is pivoted to the storage or closed
position.
[0056] In one embodiment, as illustrated in FIG. 8, the support 70
includes at least one member that is a layered member 210. The
layered member includes a substrate 208, a first adhesive layer
206, a buffer layer 204, a second adhesive layer 202, and a surface
layer 200. In one embodiment, the substrate is comprised of
melamine or a melamine based material. Melamine is a material
generally characterized by the formula C.sub.3H.sub.6N.sub.6 and
has the following chemical structure:
##STR00001##
[0057] Melamine is used to produce melamine resin, which when
combined with formaldehyde produces a very durable thermoset
plastic. This thermoset plastic has a relatively low density, is
easily machinable and highly durable. Accordingly, the melamine
based substrate is suitable for use in the pivoting support member
70. However, there is a difficultly in directly adhering the
surface layer 200 or surface veneer directly to the melamine
substrate 208. Accordingly, a buffer layer 204 or adhesion layer is
first applied to the melamine substrate 208 with a suitable
adhesive 206.
[0058] In one embodiment, the buffer layer 204 is a preprocessed
wood based veneer. In one example, the preprocessing includes
slicing, bleaching and boiling the wood based veneer to
substantially remove the oils from the wood. Thus, the buffer layer
204 is a substantially oil free wood based veneer. The wood based
veneer may include one or more types of wood, where the wood may be
African obiche wood that has been reconstituted according to the
above preprocessing methods. However, it should be appreciated that
any suitable wood may be used that has suitable adhesion properties
to the melamine based substrate 208.
[0059] In one embodiment, the first adhesive layer 206 includes an
adhesive sold under the trade name Gorilla Glue.TM.. This adhesive
includes, at least in part, a urethane prepolymer and a polymeric
MDI (4,4'-Diphenylmethane diisocyanate), where polymeric MDI is a
mixture of monomeric MDI, isomeres and a homopolymer. The urethane
prepolymer is included in a weight percent ranging from about
60-70% and the polymeric MDI is included in a weight percent
ranging from about 30-40%. It should be appreciated that any
suitable adhesive may be used in the first adhesive layer provided
that the adhesive is suitable for adhering a substantially oil free
wood based veneer to a melamine substrate.
[0060] In one embodiment, applying the buffer layer 204 or adhesion
layer to the substrate 208 includes wetting the buffer layer 204,
applying the adhesive to the buffer layer 204 or the substrate 208
to form the first adhesive layer 206, clamping the buffer layer 204
to the substrate 208, and allowing the adhesive to dry or set for
approximately five to eight hours.
[0061] In one embodiment, the second adhesive layer 202 is applied
to the upper surface of the buffer layer 204. In an embodiment, the
second adhesive layer 202 comprises a polyvinyl acetate (PVA) glue.
PVA glue is typically referred to as wood glue or carpenter's glue,
and has the following chemical structure:
##STR00002##
[0062] It should be appreciated that any suitable adhesive may be
used in the second adhesive layer 202 that sufficiently bonds the
surface layer 200 to the buffer layer 204. In an embodiment, the
surface layer 200 is a veneer having a wood grained appearance. The
wood grain can be selected to substantially mimic a surface of the
tabletop. In another embodiment, the surface layer 200 includes a
faux leather covering. It should be appreciated that the surface
layer 200 can comprise any suitable material, covering or coating,
and may further include aesthetic or tactile characteristics that
would be enhance the overall look and feel of the table.
[0063] Accordingly, by providing a buffer layer 204 or adhesive
layer between the surface layer 200 and the melamine substrate 208,
the surface layer 200 does not peel away or separate from the
underlying substrate 208.
[0064] It should be understood that various changes and
modifications to the presently preferred embodiments described
herein will be apparent to those skilled in the art. Such changes
and modifications can be made without departing from the spirit and
scope of the present subject matter and without diminishing its
intended advantages. It is therefore intended that such changes and
modifications be covered by the appended claims.
