Description




BACKGROUND OF THE INVENTION




(1) Field of the Invention




The present invention relates to a communication system comprised of a table or work area, such as a conference table, that includes a communication module positioned within a recess in the top of the table or work area. In a first embodiment, the entire module is moveable between a lowered position within the recess, and a raised position in which a part of the module projects above the table top. In a second embodiment, the top section of the module is moveable between closed and open positions, while the remainder of the module is stationary.




(2) Description of the Prior Art




Historically, a conference table, the table being used herein to identify a table used by multiple persons as a gathering place to exchange information, has been used primarily to support writing pads and other materials when a group of individuals gathered around the table for discussions. With the recent explosion of communications technologies, conference tables and adjacent areas have become cluttered with various devices and associated wiring and other connectors. Such devices include telephones, conference speakers, computers, visual screens, various audio and video recording and play-back devices, etc.




As a result, conference tables have become storage surfaces for electronic devices, with wiring being strung across the table between components, both on and adjacent the table. Consequently, the tables have diminished value as a gathering place for individuals during meetings, and are difficult to set up and disassemble after meetings. Also, issues that arise during the meeting may necessitate delays while additional electronic equipment is set up for use by the participants. Even with proper equipment in place, it is often difficult to provide equal access to the equipment by all participants, without pulling the equipment around to various locations on the table, or requiring the participants to change seats. One central visual area is also often difficult for everyone to view equally.




Numerous kinds of electronic devices are an accepted necessity for modern business, with the devices being used for communications, calculations and transmission of information. There will also be a continuing need for groups of people to access these devices as part of the decision making process. Therefore, a system in which a plurality of persons could have ready access to such devices when at a conference table would be of considerable value. In addition, a system providing access to this system without cluttering the work surface, and being easily accessed or stored, would be of further value.




SUMMARY OF THE INVENTION




The present invention addresses these needs by providing a system comprised of a conference table with an opening in the surface of the table, and a retractable communication module that is stored within this opening. In one embodiment, the entire module is moveable within this opening between a lowered or stored position beneath this opening and a raised position in which the module projects above the surface of the table. In a second embodiment, the top of the module is moveable between a lowered position and a raised position, while the remainder of the module is stationary.




The Table




The exact construction of the table forming a part of the invention is not critical, so long as the table has a top with an upper work surface, and a module opening within the work surface extending through the tabletop. The table may be designed for use by a single individual, or by multiple individuals. The tabletop may be of one-piece, or of multiple pieces that are joined permanently together. Preferably, however, the table is of a modular construction, with various tabletop sections being releasibly joined to form the tabletop. Examples of suitable tables are described in commonly assigned U.S. patent application Ser. No. 09/216,717, filed Dec. 18, 1998, now U.S. Pat. No. 6,012,398, issued Jan. 11, 2000, and U.S. patent application Ser. No. 09/409,517, filed Sep. 30, 1999, both applications being incorporated herein by reference in their entirety.




In the tables described in these applications, a plurality of three-sided segments are joined together to form a three-sided table module. A plurality of these modules are then joined together to form a modular conference table. The dimensions of the segments are such that a three-sided opening is formed in the center of the table module when the three-sided segments are joined.




The tables described in these applications also includes a leg, cover or base with a central opening beneath each opening in the module top. Preferably, the leg opening is also three-sided, with alignment and dimensions like the opening in the module top. Thus, when a table of this configuration is used in the present invention, a communication module can be positioned with a retracted position within the leg opening, and a raised position extending from the leg opening up through the opening in the module top. Alternatively, the module can be fixed within the opening in the tabletop, with the leg opening being optionally used for storage of other components. When a conference table is formed of a plurality of table modules, communications modules can be positioned in a plurality of table module openings from which they can be extended for use, or retracted so that they are hidden beneath the table.




The Module




The exact configuration of the communications module will depend upon its particular end uses, and the level of sophistication desired. Basically, the communication module comprises a housing to support one or more communications devices, and a top or outer surface that is positioned substantially in a plane with the upper surface of the table top when the module is in its lowered or closed position. The communications devices, the term being used herein to designate various electronic devices, and components thereof used to communicate information either to or from participants, may include a display screen, a video camera, a speaker, a microphone, audio and video recording or play-back devices, computers, and various jacks.




Components of these devices may also be installed in the module, with the remainder of the particular device being at a remote location. The module may also include various kinds of input and output components, such as outlets, jacks, infrared receiver and transmitter ports, and the like. These devices and components may be arranged in the housing in any suitable manner depending upon the particular devices or components, ease of access, and overall aesthetic appearance of the module.




One embodiment of the module includes a hinged top with an upper surface that is substantially in a plane with the upper surface of the tabletop when the module is in a lowered or closed position. When the module is in its raised position, the hinged top can be opened to a vertical position to provide access to devices beneath the top. For example, a display screen may be attached to the inner surface of the top, so that the screen will be positioned vertically for viewing when the top is opened. The top and attached screen can be supported on a swivel base that is rotatable about a vertical axis so that the screen can be rotated up to 360° for viewing by different individuals around the table.




In a further enhancement of this embodiment, a computer can be positioned within the housing or at a remote location, e.g., beneath the table, and connected to the display. Different participants can then access the computer through a keyboard on the table and display output from the computer on the display screen. The keyboard can be connected to the computer through a wiring jack, or via an infrared port. The display screens of several other modules can be slaved to the first module, so that the information is displayed on a plurality of display screens.




The display screen can also be attached to a remote communication source, such as an audio/video feed from a remote conference table, or other remote source. In this instance, the communication module can also include a microphone and video camera, so that two-way communication is possible between the conference table and the remote source.




The configuration of the communication module is not critical to the invention, and the electronic components do not need to be completely enclosed within the module, so long as they are protected and supported. Preferably, the top of the module, whether stationary or hinged, will have a planar upper surface with an outer periphery corresponding to the dimensions of the table opening, so that the table opening is substantially filled by the communication module top when the communication module is in the lowered position.




The cross-sectional configuration of the component enclosure beneath the top also preferably corresponds to the dimensions of the opening to provide the maximum storage space within the housing. However, the top and enclosure may be of different shapes and sizes, e.g., the top can be triangular, rectangular or round. Preferably, at least one face of the enclosure, or a portion thereof is planar to facilitate positioning of jacks and/or connectors, and to provide access to. electronic components.




The module can be mounted on a mechanism to move the module between a lowered position within the table recess, and a raised position in which the module at least partially projects above the plane of the table top. Alternatively, the module can be comprised of a fixed lower section or housing to enclose some of the components, and a top section attached to the lower section and moveable between a closed position and an open position.




Moveable Embodiment




Various means, either mechanical or electrical, can be employed to move the communications module between lowered and raised positions. In a basic embodiment, the module support includes a spring or pneumatic cylinder that urges the module toward the raised position, and a stop or latch that retains the module in the lowered position, with the latch being released or actuated by forcing the module below its lowered position.




The module in this embodiment is moved from its lowered position, in which the top of the module is in a plane with the upper surface of the tabletop, to the raised position, by pressed down on the top of the module to release the latch. The spring or pneumatic cylinder then forces the module to the raised position. The module is returned to its lowered position by pressing down on the module until the latch is again engaged.




The module can also be moved between lowered and raised positions by attaching the module through a drive means to an electric motor. For example, the module can be attached to the upper end of a rod that is raised and lowered by a worm gear or a ball screw assembly attached to the motor drive shaft. A drive belt can also be used to connect the motor to the module. The module can also be raised and lowered pneumatically by attaching the module to a cylinder that is extending and retracted by pumping air or a fluid into and out of the cylinder. The exact mechanism used to raise and lower the module is not a critical aspect of the invention, and various mechanisms will occur to one skilled in the art after becoming familiar with the invention.




If the module is raised by an electrical mechanism, the system will also include at least one switch to activate the mechanism when the module is to be raised or lowered. This switch can be on the module or at some other location on the table. Various types of switches can be used. For example, the switch may be a mechanical or capacitance switch. The invention also contemplates switches that can be remotely actuated with an infrared beam from a handset. A plurality of modules can be connected in the same circuit so that the modules are raised or lowered together upon activation of a single switch.




Stationary Embodiment




Instead of being moveable between a lowered position and a raised position, the module may be constructed of a lower section that is fixed in a stationary position within the tabletop recess, and a top section that is moveable between a closed position and a raised position. In the closed position, the rear or back surface of the top section, i.e., the upper surface of the top section when the top section is horizontal, is preferably substantially in a plane with the tabletop upper surface when in a closed position. When opened, the top section is moved to a substantially vertical position.




The front or inner surface of the top section may include a display screen and other components, such as a camera, a microphone, and speakers. The module may include some or all of the components described above, and will function in the same manner. That is, the only significant difference between the stationary module and the moveable module is the fact that the stationary module, with the exception of the module top section, remains in a stationary position, while the moveable module is vertically moveable between lowered and raised positions.




Operation




In operation, after the participants are assembled around the uncluttered table, or an individual user is seated at the table, the communication module, if the moveable embodiment, is raised either manually or electronically. If the communication module includes a hinged top with a display screen, the top is raised to the vertical position for viewing of the screen. Various electronic devices can then be accessed, depending upon the configuration of the communication module. If the display is connected to a computer located beneath the table or at a remote location, e.g, the office mainframe, one or more of the participants can access the computer through a keyboard to display information, such as an internet website or a Powerpoint presentation, on the display screen.




If the module is properly equipped, a remote location can be telephoned to initiate a telephone conference. This conference can also include video access to the remote location through the display screen, and video transmission to the remote site, if a video camera is part of the module. A mix of computer-sourced information and video communications is also contemplated, with computer-sourced information also being transmitted to and from the remote location. For example, a display screen on one module can be used to display the image of participants at a remote location, while the display screen of another module can be used to display computer-sourced information.




Accordingly, one aspect of the present invention is to provide a communication system comprising a table having a tabletop with a horizontal upper surface and at least one opening extending vertically through the tabletop; and a communication module movable along a vertical pathway through the opening between a lowered position below the tabletop and a raised position in which at least of a part of the communication module extends through the opening above the upper surface of the tabletop.




Another aspect of the present invention is to provide a communication system comprised of a table having a tabletop with a horizontal upper surface and at least one opening extending vertically through the tabletop; and a communication module having a stored position and a raised position, the module including a display screen moveable between a horizontal position when the module is in the stored position, and a vertical position when the module is in the raised position.




Still another aspect of the present invention is to provide a communication system adapted to communicate with a remote source, the system comprising a table having a tabletop with a horizontal upper surface and at least one opening extending vertically through the tabletop; and a communication module a display screen; and a drive means adapted to move the display screen vertically between a stored position and a raised position wherein the display screen projects above the tabletop upper surface.




Another aspect of the invention is to provide a communication system comprising a table having a tabletop with a horizontal upper surface and at least one opening extending vertically through the tabletop; and a communication module positioned within the opening, the module including a top movable between a closed horizontal position, and an open vertical position.




Another aspect of the present invention is to provide a communication system comprised of a table having a tabletop with a horizontal upper surface and at least one opening extending vertically through the tabletop; and a communication module positioned in the table opening, the module including a display screen moveable between a horizontal position when the module is in the stored position, and a vertical position when the module is in the raised position.

can be connected to a remote input or output device, such as computer, and thereby a database or the internet, a remote telephone transmission, etc., so that remote communications, data, and other information can be received by the communication module. Also, communications, data, and other information can be sent from the communication module to the input or output device.




Thus, for example, a group of individuals sitting around a conference table can use the communication module, or a group of the modules, to access stored computer data, including textual and numerical data, and manipulate the data. In another application, the internet can be accessed and the selected website displayed to the participants, with each individual, with an appropriately connected keyboard being able to access desired URLs, send email, etc. The participants can also engage in conference calls with one or more remote locations, with data or images or the remotely located individuals being displayed on the screen, and images of the participants being transmitted to the remote location using the digital camera.




The module shown in

FIGS. 8-11

are used in the same manner except that the top section is pressed downward to disengage the latch and then raised, manually or under the influence of a spring, to the vertical position. Once open, the modules function in the same manner as the modules described above.




Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. For example, instead of a rectangular screen, a triangular or circular screen can be used. Also, instead of relatively small individual units as illustrated, a single larger unit can be used. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the follow claims.
