Table with multiple configurations
A table includes a plurality of surface sections joined to a base. At least one of the surface sections is joined to the base with an attachment device having a slidable portion and a rotatable portion. A mounted end of the slidable portion is secured to the base and the opposite end of the slidable portion is slidably coupled to a rotatable joint, which is mounted to one of the surface sections. The rotatable joint is configured to rotate relative to the base, so that the surface section can be translated and rotated relative to the base to enable the table to readily be changed into four different configurations. Utility trays mounted under the surface sections provide access to power and data leads feeding from the base. A pleated accordion fold cover hides the attachment device and leads when a gap is formed between the surface sections.
The present invention generally pertains to conference tables, and more specifically, to conference tables that are selectively configurable in a plurality of different configurations.
BACKGROUND OF THE INVENTIONMost office suites include one or more conference rooms. These conference rooms may be used for any number of functions, but are typically used for meetings in which participants are seated around a table to discuss matters of interest to the participants. While a single conference table with seating on both sides can server this function, there are times when it is desirable to provide two sets of tables that are spaced apart from each other longitudinally. For example, it might be desirable to seat opposing parties along opposite sides of spaced-apart tables during negotiations. Still further, conference rooms might host presentations where a presenter, standing at one end of the table and using one or more visual aids, such as a video screen or monitor mounted on the wall at the opposite end of the table, addresses a number of participants seated around the table.
One way that has been developed in the prior art to make the furniture in a conference room more adaptable to different purposes and needs is to use two narrower tables, such as conference tables 112b and 114b, as shown in a conference room 100b illustrated in
This prior art solution to the problem of achieving multiple configurations to address different functions and needs for conference tables unfortunately also has drawbacks. For example, even if tables 112b and 114b are narrower than a single conference table, such as conference table 110a (shown in
For still other purposes, such as hosting a meeting between opposing parties in a negotiation,
Furthermore, as is the case in most meetings, people seated at conference tables 112b and 114b may need to use laptop computers and other devices. As a result, power cords, telephone cords, network cables, and other wiring, such as a video data lead for monitor 160, might need to be run to computers or other data device disposed on one or both of conference tables 112b and 114b. The use of laptops and other digital devices in conference rooms has become so prevalent that conference tables that are not intended to be moved about within a conference room are often provided with longitudinally extending cable trays disposed under the surface of the conference table, so that the data ports for digital (and even optical connections), and AC power strips disposed in the tray are accessed through a slot in the surface of conference table overlying the tray. These digital and power leads typically feed down through the supports for the conference table and into trays hidden under the flooring. Unfortunately, because one of the objects of using two separate tables 112b and 114b is to permit the reconfiguration of the conference tables to be readily carried out by moving the conference tables, it is not practical to equip these movable conference tables with cabling trays and conduits, since the data and power leads would then be exposed when the tables are moved to achieve the different configurations, creating a tripping hazard. As a result, when computers and other digital devices are used on conference tables 112b and 114b, the various data and power cords and cables will be run as needed, potentially presenting a tripping hazard and at least creating an inconvenient, tangled, and untidy set of leads, which might extend between the conference tables, e.g., hanging in gap 116 between tables 112b and 114b as shown in
Considering the examples of
Accordingly, one of the advantages of the present invention is that it provides a table that can readily be configured to suit a number of different uses or functions. As a result, a space such as a conference room that is equipped with such a table can be efficiently used for different purposes without having to exchange or move furniture around the room. For example, if a pair of separate but facing tables are needed, sections of the table, which are rotatably supported by a base, can be moved apart to present generally parallel, spaced-apart table sections, thereby avoiding the need to bring an additional table into the room. Alternatively, one or more table sections can be rotated relative to the base to present a “V” shape configuration of the table sections that is selectively open at either end of the table to enable people seated around the table to more easily view a speaker and/or another object of interest, such as a display screen or monitor, disposed at open end of the “V” shape configuration.
The table sections are supported by the base and preferably, at other points adjacent to their ends, by a plurality of table supports. Each table support engages only one of the table sections, so as to avoid interfering when one of the table sections is moved relative to another table section. The lower end of each of the table supports preferably includes a device for reducing friction, such as a sliding surface or a caster, to further facilitate movement of the table sections while at least partially supported by the table supports.
In addition, one embodiment of the present invention includes utility trays that extend along the undersurface of the table sections and which are configured to receive cables and leads that pass through the base of the table. Included within the utility trays are electrical power strips that are connected to a source of alternating current through leads that extend downwardly through the base. The cables and leads within the utility trays can be accessed at different points along the length of the table sections. As a result, even when table sections are moved, connections to the cables and leads disposed within the utility tray are available through an opening into the utility tray through the table surface. Persons seated around the table are thus provided ready access to integral data and electrical connections within the utility trays. To further enhance the appearance of the table surface system and hide the cables and leads that are conveyed to the utility trays, an extensible cover is joined to each of the table sections so that as the table sections are moved relative to one another, the extensible cover continuously covers the cables and leads that are conveyed through an opening at the top of the base.
One aspect of the present invention as claimed is thus directed to a table system. The table system includes a base, a first surface section having a first inside edge, and a second surface section having a second inside edge. The second inside edge is configured to abut the first inside edge of the first surface section so that when thus arranged, the first surface section and the second surface section form a combined table surface. Also included is a first attachment device that translatably and rotatably secures the first surface section to the base. The first attachment device includes a first attachment end having a rotatable joint that is joined to one of the base and the first surface section, and a second attachment end that includes a slidable member slidably coupled to the rotatable joint and joined to the other of the base and the first surface section to which the first attachment end is not joined. A second attachment device secures the second surface section to the base.
The second attachment device preferably also movably joins the second surface section to the base such that the second surface section is translatable and rotatable relative to the base. Accordingly, the second attachment device includes a first attachment end having a rotatable joint that is joined to one of the base and the second surface section, and a second attachment end that includes a slidable member slidably coupled to the rotatable joint and joined to the other of the base and the second surface section to which the first attachment end is not joined
At least one of the first surface section and the second surface section preferably includes a utility tray extending below the surface section. The surface section that includes the utility tray is then secured to at least one of the first attachment device and the second attachment device at the utility tray. An interior channel is defined by the utility tray and is configured to receive a plurality of wires extending from the base. The interior channel conveys the wires generally parallel to the inside edge of the surface section.
At least one access opening is provided in an upper face of at least one of the first and the second surface sections, to provide access to the interior channel. The access opening includes a closure device enabling the access opening in the upper face of the surface section to be selectively partially closed.
The table system also includes a plurality of table supports that support each of the first and the second surface sections. The table supports each have opposed first and second ends, and the first end is secured to one of the first and the second surface sections, while the second end is supported by an underlying floor surface. Preferably, the second end of the table support includes either a sliding surface or a caster to facilitate movement of the second end of table support across the underlying floor surface.
An extensible cover is secured over a top of the base to at least partially cover an opening formed between the first inside edge and the second inside edge when at least one of the surface sections is moved relative to the base, to create a gap between the two surface sections. The opening is adapted to convey leads from inside the base toward each of the first and the second surface sections.
Another aspect of the present invention is directed to a method for supporting a plurality of table sections to enable the plurality of table sections to be arranged in a plurality of configurations relative to a base that supports the table sections. The method recites steps that are generally consistent with the functions of the table system discussed above.
BRIEF DESCRIPTION OF THE DRAWINGS FIGURESThe foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
Structure of Multipurpose Conference Room Table
Tabletop 210 is supported by a base 250 and a plurality of table supports or legs 280. Base 250 supports tabletop 210 approximately at a midpoint of tabletop 210. More particularly, in the embodiment of the present invention shown in
As shown in
As illustrated in
Utility trays 220 may be integrally formed into surface sections 212, but in the embodiment shown in
Attachment mechanism 254 thus supports a plurality of rotatable joints 256 that are slidably mounted to the base as described below. Surface sections 212 are coupled to rotatable joints 256 via utility trays 220. Accordingly, as will be further appreciated from the discussion that follows, surface sections 212 of tabletop 210 can be both translated laterally and rotated with respect to base 250.
Legs 280 include inner support braces 281, which provide internal structural support to the legs. In the embodiment of the invention shown in
Mechanism Providing for Configurability of Surface Sections
Upper edges 259 of base 250 engage and support a lower surface 261 of attachment mechanism 254, which provides supports for rotatable joints 256. Rotatable joints 256 preferably comprise bearing-supported turntables such that, when coupled to the surface sections of the tabletop (not shown in
In particular, attachment mechanism 254 includes a support panel 258 to which are mounted channel mounts 260. Slidable channels 262 are preferably slidably bearing-mounted to mounted to channel mounts 260 and include channel stops, such as stop blocks 268, to limit the travel of slidable channels 262. Limiting the travel of slidable channels 262 allows adjustment to the range of motion the table sections (not shown) to suit the size of the room where the table will be located. In the example shown, stop blocks 268 extend through a lower portion of support member 254 and block further travel of slidable channels 262 when the desired limit of their travel is reached.
Bases 264 of rotatable joints 256 are coupled with slidable channels 262, and rotatable upper portions 266 of rotatable joints 256 are rotatably secured to joint bases 264. Thus, securing the surface sections of the table to rotatable upper portions 266 of rotatable joints 256 enables the surface sections to be rotated relative to joint bases 264 of rotatable joints 256. Also, slidable channels 262 are laterally translatable relative to channel mounts 260, such that rotatable joints 256 are translatable relative to support member 254 along the line of travel of slidable channels 262.
Preferably, rotatable upper portions 266 of rotatable joints 256 engage the surface sections via tension mounts 270 to flexibly, yet securely, join the surface sections to attachment mechanism 254. Attachment mechanism 254 also preferably includes wiring orifices 272 enabling wiring or leads (not shown) that extend through a central channel 274 of base 250 to pass through and on to utility trays 220, as explained below.
It is contemplated that in other embodiments (not shown), the surface sections can be attached to the base in other ways that still enable the surface sections to be translated and rotated relative to the base. For example, one surface section may be fixedly mounted to the base, while the adjacent surface section is movably mounted on the base, so as to be rotatable and translatable with respect to the base (and the other surface section). In addition, if both surface sections are coupled to rotatable joints that are slidably mounted to the base, the rotatable joints may be slidably mounted to opposing ends of a single support member, or the rotatable joints may be slidably mounted to separate support members. Further, although
In one alternative embodiment of the present invention, surface sections 212 integrally include utility trays 220. However, in the illustrated embodiment shown in

Similarly, in
It should be appreciated that caster locks (not separately shown) may be provided on casters 282 or other sliding or rolling devices that are disposed on the bottom of the legs and used to secure table 200 in any of positions 800, 820, 840, and 860 to prevent the table from being unintentionally moved out of the desired configuration as a result of people bumping into the table or otherwise pressing against surface sections 212a-212d.
Extensible Cover Overlying the Gap Between Table Sections
As described in connection with
Preferably, extensible cover 910a includes an opaque material that conceals objects under the extensible cover. In particular, extensible cover 910a conceals a top end of base 250 and leads 226 extending from base 250 along slidable channels 262a/b and 262c/d. Slidable channels 262a/b and 262c/d travel on channel mount (not shown in
As illustrated in
Thus, extensible cover 910a-910b provides an automatically adaptable covering for any potential gap that may form between the surface sections when the table is reconfigured from any retracted position to any extended position and back. It should be noted that an extensible covering may comprise material other than pleated accordion fold covering. Extensible covering 910a-910b also may include elastic materials or scissor-folding materials that can be stretched or extended, to cover a variable-size gap formed between the joined surface sections.
Logical Steps for Assembling and Using the Reconfigurable Table
At a step 1010, leads are extended from the base through the wiring orifice of the attachment mechanism and into the interior channels of the utility trays. Alternatively, if interior channels of the utility trays are preinstalled with one or more wiring harnesses, the wiring harnesses are joined with wiring extending up through the base or are coupled to external wiring in a utility box set into the flooring under the table. At a step 1012, the legs are connected to the ends of the utility trays, if desired, at positions away from the base. Alternatively, the legs may be connected only to the surface sections if desired. At a step 1014, the surface sections are secured to the utility trays and/or to the legs directly. At a step 1016, an extensible gap covering is secured to the inside edges of the surface sections, or otherwise joined to the surface sections, as described above. The table is now assembled and ready for use.
Now that the table is assembled, at a decision step 1018, it is determined if the surface sections are configured as desired. If so, flow diagram 1000 ends at a step 1024. However, if the surface sections are not in the desired configuration, at a step 1020, the surface sections are translated using the slidable channels, and, at a step 1022, the surface sections are rotated to a desired angular orientation, using the rotatable joints. It will be appreciated that steps 1020 and 1022 can be undertaken concurrently, because the surface sections can be both translated and rotated at the same time, as described above. After the surface sections are translated and rotated, flow diagram 1000 loops to decision step 1018 to determine if the surface sections now are in a desired configuration If so, the flow diagram ends at step 1024. However, if the surface sections are still not in a desired configuration, steps 1020 and 1022 are repeated. It should be appreciated that steps 1018, 1020, and 1022, maybe performed as often as desired to change the table to a different configuration suitable for a particular purpose.
Although the present invention has been described in connection with the preferred form of practicing it and modifications thereto, those of ordinary skill in the art will understand that many other modifications can be made to the present invention within the scope of the claims that follow.
