Abstract
A dual use article of furniture with horizontally supported planar surfaces that separate, slide, and pivot to provide adjustable passage for electrical wiring communication, concealment, and management, and to provide access to electrical and electronic components, and accessories internally stored and supported beneath the planar surface and concealed by a relatively movable assembly that is connected to, supported by, and integral with the article of furniture structure.
Description
- 1. Field of the Invention
- This invention relates to articles of furniture with horizontally supported planar surfaces that separate, slide, and pivot to provide adjustable passage for electrical wiring communication, its concealment, and its management, and to provide access for electrical and electronic components, and for accessories internally supported beneath the planar surface and concealed by a relatively movable assembly that is connected to, supported by, and integral with the article of furniture structure. More particularly this invention relates to dual use articles of furniture whose principal function is readily converted to an article of furniture with the top surface available for manual tasks.
- Embodiments of wiring and accessory management furniture are represented by credenzas, computer workstations, audio equipment cabinets, communication kiosks, and point-of-sale equipment cabinets.
- 2. Description of the Related Art
- With the proliferation of electronic and computer equipment, equipment furniture and cabinetry has become a tangle of wiring requiring organization and concealment. Additionally, the equipment and accessories themselves require organization, provision of space, and concealment. Thus the prior art of furniture and cabinetry lacks the ease and scale of the combination of wiring passage with internal access to secondary equipment storage.
- In order to overcome the above shortcomings within the prior art the present disclosure briefly stated is a wire and accessory accessibility structure and management system for use as a structural component of an article of furniture for at least one individual user having a top surface possessing a surface portion that slides to provide at least one adjustable wiring passage gap for generally the extent of the top, and that slideable surface portion also being pivotable to provide at least one opening for internal access with one structural distinction being that the sliding adjustment direction is orthogonal and at generally right angles to an axis of pivot that is disposed generally peripheral to the top surface. A further structural distinction being that means are provided for linearly limiting the sliding movement. A still further structural distinction being that structural support is provided for that slideable and pivotable surface portion while providing the necessary bracing rigidity to the parent structure comprising a top surface and supporting members or legs. Thus, the present disclosure provides wiring and accessory management that is integral with the structure of the article of furniture rather than simply providing holes, ports, and raceways that are appendages of the article.
- The present disclosure relates to an article of furniture comprising a top surface comprising; a top piece adjacent to and in non-permanent contact with, at least one top extension with an inward edge and an outward edge, at least one top extension pivotally disposed for bi-directional rotation, and at least one top extension further adjustably disposed for bi-directional slidable movement orthogonal to the axis of pivot, wherein the top surface is adjacent to and supported by, at least two members, at least one structural element disposed below the top surface to provide for structural rigidity and support, whereby at least one pivotally disposed and bi-directional adjustably and slidably disposed top extension is selected for gap creation between the top piece and at least one top extension for electrical cord and accessory cable passage and accommodation and further for access beneath the top surface.
- A portion of the top surface of the article of furniture comprises a generally horizontal work surface. In the present disclosure a generally horizontal work surface of an article of furniture is defined as varying less than 10 degrees from level measured front to back. For the purposes of the present disclosure the work surface is the portion of the top surface of the furniture that is likely to be in immediate and direct contact with the hands and lower arms of a user during normal activities such as reading, writing, or using a computer input device. This working surface is defined as a minimum of at least eighteen inches wide and fourteen inches deep.
- For the purposes of the present disclosure the dimensions of the top surface of an individual article of furniture such as a desk is defined as being less that eight feet in length and less that five feet deep exclusive of extensions or returns. The primary material of an article of furniture may be wood, metal, glass, or composites.
- The present disclosure relates to an article of furniture wherein the non-permanent contact comprises a compatible and common contour for generally the extant of the top piece. The top surface comprises a top piece adjacent to and in non-permanent contact with at least one top extension. Thus the article of furniture has a seam or contact junction in the top surface. This seam or contact junction can be straight, curved, or made up of a combination of multiple straight or curve lines when viewed in plan. An example of straight seam is shown in
FIG. 1 , and an example of curved seam is shown inFIGS. 5 and 6 . The vertical component of the seam can also vary from a butt joint as shown for example inFIG. 3 to an interlocking seam as shown for example inFIG. 15 . - The top extension is pivotally disposed for bi-directional rotation to provide access beneath the top surface. A pivoting mechanism disposes the top extension for this bi-directional rotation. An example of a pivoting mechanism is a hinge. It will be understood by one skilled in the art that a multitude of pivoting means can be employed comprising hinges, pins, and flexible membranes. For the purposes of the present disclosure a hinge is defined as a device that permits and enables pivotable movement about a pivot point or axis during operation. A hinge comprises a hinged and swingable member, a fixed member, and a hinge pin. The axis of a hinge is the pivot point about which a hinged member rotates during operation of the hinge.
- For the purposes of the present disclosure a hinged member is any device or portion thereof (e.g., top extension, closure, side, fascia, etc.) which is adapted to be swingably connected by a hinge to a fixed member, support, or sill. The hinge pin is any elongated rodlike element or pintle about which a hinged member swings. The hinge leaf is a platelike portion by which the hinge is adapted to be secured to a hinged member. For the purposes of this invention an adjustable hinge is a hinge that includes slideable components that provide for changing relative orientation of the hinged member with regard to the fixed member and perpendicular to the hinge axis. Any pivoting mechanism that provides for this bi-directional rotation of the top extension is applicable in the present disclosure.
- The present disclosure relates to an article of furniture wherein the axis of pivot is outward of the top surface. The current invention teaches that the center of pivot is always outward of the top surface. To a seated user of the article of furniture the center of pivot may be right, left, or forward of the user. The center of pivot is generally in a plane that is proximate to either the inside or the outside faces of the fascia. It will be understood by one skilled in the art that pivoting mechanisms may be utilized to vary this center of pivot within the general area at any level below the top surface of the desk. The current invention teaches that when an embodiment incorporates a hinge for the pivot mechanism, the hinge is always positioned to provide both pivoting movement and structural support to the moveable components of the current invention. For example in
FIG. 2 the hinge is shown on the exterior face of the fascia with a pivot point proximate to that outside face, and the hinge with its fixed leaf attached to the fascia supports the top extension. - The top extension is further adjustably disposed for bi-directional slideable movement orthogonal to the axis of pivot selected for gap creation between the top piece and the top extension for electrical cord and wire passage and accommodation. The non-permanent contact comprises a generally compatible and common contour for generally the extant of the top piece. The axis of pivot is outward of the top surface. For the purposes of the present disclosure, extant of the top piece means either generally the length or generally the width of the top piece.
- The dimensional limits on the slideability and therefore the width of the gap and slot that the slideability generates are dependent upon the thickest diameter of wire that will be passed through the gap but in no case will be less than one eighth inch. The gap is opened in a uniform top surface by the sliding of the top piece in relation to the top extension which are structural components of the desk top. This bi-directionally adjustable motion is enabled, managed, and controlled by the incorporation of a sliding mechanism. Many mechanisms can fulfill this sliding function but they all comprise at least two components, a fixed track and a moveable car that follows the track.
FIGS. 4 and 13 show two types of track fixtures. FIGS. 3,7,8,9,11,12,14,15 show various combinations of tracks with compatible moveable cars which may be pins, screws, or runners. - The current disclosure incorporates in various embodiments fixtures such as brackets or hinges that incorporate tracks for pins or screw fasteners that are loose enough to allow bi-directional movement yet maintain a firm sliding connection. Linear movement along the track is preferred to avoid jamming the pins in the track or jamming the component to which the fixture is attached against fixed components. Thus for the purposes of this invention a tracked fixture will generate acceptable linear movement if two pins or screws are spaced more than eight times the pin or screw diameter measured along a line parallel to the direction of desired bi-directional movement. For example in
FIG. 3 the fastener pin orscrew 21 has a diameter that is smaller than theslot 23 in which it slides. If there were no lateral constraint this pin would allow skewed motion as the top extension is moved back and forth as indicated byarrow 28. However further lateral constrain is provided by slot 24 with fastener pin or screw 22. The two moveable screws are shown to be more than eight times their diameters apart providing the desired non-binding linear movement. This teaching is further shown in detail of hinges and fixtures inFIGS. 4 and 13 . - The top surface is adjacent to and supported by at least two members. For the purposes of the present disclosure the members may be two large, nearly immovable members such as pedestals, cubical dividers, or they may have be four or more legs communicating with the floor for support.
- At least one structural element is disposed below the top surface to provide for structural rigidity and support. A brace, truss, shelf, and fascia are applicable as structural elements. A structural element is any element below the top surface that provides structural support and rigidity directly and/or indirectly to the overall structure and/or at least one member and/or at least one structural and/or non-structural element. A structural element is adjacent to and connected to directly and/or indirectly at least one structural and/or non-structural element to provide the aforementioned structural support and rigidity. Thus at least one structural element is utilized to produce the rigid structure required for an article of furniture in daily use.
- At least one pivotally disposed and bi-directional adjustably and slideably disposed top extension is selected for gap creation between the top piece and at least one top extension for electrical cord passage and accommodation and for access beneath the top surface. The flexibility of the top surface design allows top extension adjustable and slideable bi-directional movement for the variable creation of at least one gap the extent of top surface length or at least one gap the extent of the top surface width depending on the degree of cord management desired. This flexibility provides for variable gap location and positioning that can easily be eliminated when cord management is not required. Although the provision of both motions may be combined in a single mechanism, the bi-directional adjustable and slideable movement is completely independent of the pivoting movement. At least one pivotally disposed top extension enables bi-directional rotation to enable flexibility for variable gap location and positioning, providing for access beneath the top surface where desired.
- The present disclosure relates to an article of furniture wherein at least one structural element comprises a shelf disposed below top surface, at least one structural element shelf adjacent to and in contact with at least one member, at least one structural element shelf providing for accessory accommodation and structural rigidity and support. For the purpose of the present disclosure a shelf is a generally horizontal surface that is substantially longer that it is wide, and is supported either at the ends or underneath by the basic structural members of the desk. It will be understood by one skilled in the art that a shelf may add structural stability to the desk either as a beam, or in diaphragm action, or by rigid connection to intermediate structural components that reinforce the members.
- One embodiment of the present disclosure is as a free standing desk with legs or members for individual work possessing structural elements providing an interior shelf and space for electronic and computer components, accessories, and wiring. A gap and slot between the working surface of the desk and the assembly serves to allow wiring to communicate between the desktop computer components and the unseen accessories and operating electronic support elements. This gap is manually adjustable in width. Electrical power is fed to the desk from below and behind the shelf, and then to power distribution strips and power supplies on or adjacent to the interior shelf. Many small low voltage transformers required for printers and speakers may be accommodated on this shelf.
- The present disclosure relates to an article of furniture wherein at least one top extension is connected to at least one structural element fascia by at least one adjustable hinge, at least one adjustable hinge disposed for orientation variability of at least one top extension and at least one structural element fascia to provide constrained bi-directional linear guidance of at least one top extension and at least one structural element fascia orthogonal to the axis of the hinge. The structural element fascia may provide support for the top extension through one piano hinge, being a single long hinge, or through a series of hinges or pins all having the same center of pivot. The hinge possesses adjustment for slideably changing the relative orientation of various hinged members so as to provide for their constrained linear guidance bi-directionally orthogonal to the axis of the hinge.
- The present disclosure relates to an article of furniture comprising: a top surface comprising; a top piece adjacent to and in non-permanent contact with, at least one top extension with an inward edge and an outward edge, at least one top extension adjustably disposed for bi-directional slideable movement, wherein the top surface is adjacent to and supported by, at least two members, at least one structural element comprising a shelf, with an inward edge and an outward edge, disposed below the top surface, at least one structural element shelf adjacent to and connected to at least one member, at least one structural element shelf providing for accessory accommodation and structural rigidity and support, at least one structural element comprising a generally vertical fascia panel adjacent to and connected to and further disposed below at least one top extension outward of the top surface, further at least one structural element fascia is connected to the outward edge of at least one structural element shelf by at least one hinge pivotally disposed for bi-directional rotation of at least one structural element fascia and at least one top extension, further at least one top extension bi-directional slideable movement is disposed orthogonal to the axis of pivot, whereby at least one bi-directional adjustably and slidably disposed top extension is selected for gap creation between the top piece and at least one top extension for electrical cord and accessory cable passage and accommodation, whereby at least one structural element fascia and at least one top extension bi-directional rotation is selected for access beneath the top surface.
- One embodiment of the present disclosure is as a free standing desk with legs or members for individual work possessing structural elements providing an interior shelf and space for electronic and computer components, accessories, and wiring. The shelf is accessible by releasing a catch or dead bolt and folding outward an assembly independent of the working surface consisting of an extension of the desktop surface fixed to a portion of the side fascia of the desk. A gap and slot between the working surface of the desk and the assembly serves to allow wiring to communicate between the desktop computer components and the unseen accessories and operating electronic support elements. This gap is manually adjustable in width. Electrical power is fed to the desk from below and behind the shelf, and then to power distribution strips and power supplies on or adjacent to the interior shelf. Many small low voltage transformers required for printers and speakers may be accommodated on this shelf. The bi-directional slideable movement of the top extension is independent of the fascia and top extension bi-directional rotation.
- The article of furniture may have a modesty screen and drawers, one or more of which may be pulled out to reveal an accessory.
- The present disclosure relates to an article of furniture wherein bi-directional rotation of at least one structural element fascia and at least one top extension is adjustable and limited.
- The front edges of desks are often used instead of chairs. Thus any desk with a pivoting edges should also incorporate means to prevent unwanted release of structural support. Thus the pivoting mechanism includes means to provide a limit of downward rotational movement. An example of means for support is a dead bolt such as shown in FIG. 11 in the locked position and in
FIG. 12 in the open and unlocked position. It will be understood by one skilled in the art that various other mechanisms are equally useful in preventing unwanted rotation of the top extension as well as limiting the degree to which that rotation takes place on the downward swing. An example of such a swing limited means would be a short chain. - The present disclosure relates to an article of furniture wherein at least one structural element fascia is connected to at least one top extension by at least one tracked bracket. Examples of tracked brackets and fixtures are shown in
FIGS. 4 and 13 . - The present disclosure relates to an article of furniture comprising: a top surface comprising; a top piece with an inward edge and an outward edge, the top piece adjustably disposed for bi-directional slideable movement and adjacent to and in non-permanent contact with, at least one top extension pivotally disposed for bi-directional rotation, further the top piece disposed for bi-directional slideable movement rthogonal to the axis of pivot, wherein the top surface is adjacent to and supported by, at least two members, at least one structural element disposed below the top surface to provide for structural rigidity and support, whereby the bi-directional adjustably and slidably disposed top piece is selected for gap creation between the top piece and at least one top extension for electrical wire, cord, and accessory cable passage and accommodation, whereby at least one pivotally disposed top extension is selected for access beneath the top surface.
- The management component of the wiring and accessory management is resident within the current invention because of the provisions for segregation, scale of accommodation, scale of access, flexibility of arrangement, and preservation of aesthetics.
- The provision for segregation is manifest because the present disclosure provides passage of wiring to equipment while at the same time providing access and support that is topologically relational to the segregation between the primary man-equipment interface components and the secondary non-interface, passive, supportive equipment components. Examples of man-equipment interface components are computer keyboards, monitors, mice, removable disk drives, and microphones. Non-computer examples of such interfaces are telephones, clocks, audio dials, and electrical switches. Examples of supportive but generally inert, passive equipment are power strips, un-interruptible power supplies, speakers, fixed disk drives, routers, hubs, cable modems, transformers, amplifiers, and computers. Thus the present disclosure provides means for segregation of man-equipment interface imperative electronic components from non-interface imperative electronic components.
- The scale of accommodation is manifest due to providing wiring passage through a gap that is generally the full width or length or extant of the top surface of the article of furniture. For example wiring for interface devices need not be either draped over the edge of a desk or bundled into ports or holes of limited size and location. The length of the wiring passage gap at generally the extant of the top surface provides the ability to move and drag a wiring passage from one spot on the desktop to another during work activities. Thus the present disclosure provides means for a multitude of top surface wiring passage points without modification to the desk structure. For the purposes of this invention a multitude is more than 25.
- The scale of access is manifest due to providing access through the top surface that is generally the extant of the top surface in length and more than 10% and less that 50% of the opposing extant of the top surface in width. Thus between 10% and 50% of the top surface can pivot to provide easy internal access to both accessories and wiring storage. Thus the present disclosure provides means for access to a substantial portion of the internal volume of the article of furniture.
- The flexibility of arrangement is manifest because of the provision for arranging the desktop for preferred utility. For example depending upon seating posture and ergonomic habits of the individual user the wiring passage for an input device may be situated nearly anywhere on the desktop outside of the immediate work area based on personal preference. Thus the present disclosure provides means for rearranging top surface wiring passage points without modification to the desk structure or rearrangement of the interface components on the top surface during desktop activities of the individual user.
- The preservation of aesthetics is manifest because of concealment of wiring and accessories without the use of ports, holes, or trapdoors.
- The preservation of aesthetes is further manifest because of the ability to restore an attractive article of furniture to its original, uncluttered, and closed configuration when computer access is not required and interface components are stored or concealed. For example an article of period furniture in the style of a Colonial Early American library table incorporating the current disclosure and used for a computer workstation can regain its original aesthetic integrity by having its interface components cleared from the desktop and having the gap slid shut. In addition management is manifest since in this closed state the library table continues to provide concealment of components and wiring after individual user activities have ceased. Thus, the present disclosure provides means for conversion from the unspoiled surfaces of an attractive article of furniture to an electronic workstation and back again while still concealing wiring and accessories during these conversion phases.
- The structural element is represented in the frame and panel desks by the fascia, and in the period desk by the shelf. The slideable element is represented in the frame desk by the sliding track for the fasteners such as cap-headed screws within the hinge, in the panel desk by the junction of the moveable surfaces between the bolster and the top extension, and in the period desk by the sliding track for the fasteners such as cap-headed screws within the tracked fixture. In
FIG. 14-15 the sliding element is represented by the moveable junction of the surfaces between the bolster and the top piece. Any mechanism or means to provide the facile and predictable bi-directional sliding of the components and elements of the current disclosure is applicable. - The pivot point in the frame desk is proximate to the junction of the top extension and the fascia. The pivot point in the panel desk is proximate to the outward point of the track within the member. The pivot point of the period desk is proximate to the junction of the fascia and the shelf.

FIG. 1 shows the wiring and equipment concealment utility of the present disclosure applied to a framed desk.Members 2 and 3 support a top surface comprised of atop piece 1 and the top extension 4. Thetop piece 1 and the top extension are shown in contact and congruent at their inner edges to form a closed gap 5. The top piece is supported by twomembers 2 and 3 that are laterally stabilized byfascia 10. Thefascia 10 provides support for top extension 4. Top extension 4 has means to adjustably slide both toward and away from gap 5 as indicated by bi-directional arrow 11. Top extension 4 also has means to pivot outward about an axis that is generally parallel with its long dimension as shown by arrow 6. This ability to pivot by the top extension 4 provides access to various computing devices, accessories, and wiring that are stored below the top extension 4. Thefascia 10 conceals these devices from forward view while the top extension 4 provides concealment from view above. -
FIG. 2 shows the wiring communication afforded by the present disclosure. Thetop piece 1 is supported by twomembers 2 and 3 that are stabilized byfascia 10. A mouse 8, a keyboard 7, and a monitor 9 are input and output devices of a computing device concealed below the extension to the top 4 and communicating by wiring with the input/output devices through various points along the longitudinal slot 5. Afascia 10 conceals computing devices, accessories, and wiring from frontal view. Top extension 4 provides concealment from view above. Top extension 4 has means to adjustably slide in the generally horizontal plane of thetop piece 1 and top extension 4 being together the top surface while being supported. Top extension 4 also has means for being linearly guided from skewing diversion during sliding both toward and away from gap 5 as indicated by bi-directional arrow 11. Top extension 4 also has means to pivot outward about an axis that is generally parallel with its long dimension as shown by arrow 6 to provide access beneath top extension 4 and behindfascia 10. -
FIG. 3 shows the relationship between the various movable and fixed components of the present disclosure. Atop piece 15 is separated from the extension to the top 16 by the gap betweenpoints arrow 28 and pivotable as indicated by arrows 27. When desired, the gap betweenpoints top extension 16 toward thetop piece 15 which is enabled by the slottedholes 23,24. Thetop extension 16 is supported by the fixedfascia 17 and the two are connected for slideable and swingable movement of thetop extension 16 byhinge 18. Thehinge 18 is slideablely connected to thetop extension 16 by cap headedscrew fasteners 21 and 22 through slottedholes 23 and 24 that form a track for bi-directional movement of the fasteners within the track. The fixed leaf of thehinge 18 is connected to the hinge sill andfascia 17 by fixedfasteners hinge 18. Thefascia 17 is connected to theshelf 29 byfastener 30 which supports a supportiveelectronic component 31 withpower supply wire 13. Access for thepower supply wiring 13 is provided through the internal opening between thetop extension 16 and theshelf 29 rearward of the shelf.
