Definitions

  • the present invention generally relates to ceiling systems, and more particularly to suspended ceiling systems which create a seamless appearance.
  • acoustic ceilings which are integrally formed with the top surface of a space sacrifice significant acoustic performance in favor of a very uniform and seamless visual appearance.
  • acoustic ceilings formed of acoustic ceiling panels installed within a grid system are able to significantly increase the acoustic performance of the acoustic ceiling, but only at the sacrifice of a seamless visual appearance.
  • Acoustic ceilings have therefore been introduced which hide the grid system, by concealing it within the edges of the supported acoustic celling panels, in order to present a more visually appealing appearance to the ceiling.
  • an improved ceiling system is desirable, particularly one which is better able to decouple visual appearance from acoustic performance.
  • the present invention provides a ceiling system which includes a ceiling structure suspended from an overhead structure, such that the ceiling structure provides a seamless visual appearance and offers the ability to fine tune the acoustic properties of the ceiling system without altering or affecting the overall visual appearance.
  • the seamless visual appearance is achieved by stretching a single sheet of fabric across an entire ceiling structure, which may be formed of a frame, may include a grid of acoustic ceiling panels, and may be suspended from an overhead structure within a space free from direct attachment to walls or other similar ceiling structures.
  • a ceiling system includes a ceiling structure suspended in an interior space.
  • the ceiling structure includes: a perimeter frame defining a central opening, the perimeter frame comprising a fabric gripping member; a support grid comprising a plurality of intersecting struts defining a plurality of grid openings, the support grid disposed within the central opening and coupled to the perimeter frame; a plurality of acoustic ceiling panels, each of the acoustic ceiling panels mounted to the support grid and disposed in one of the grid openings; and a tensioned fabric sheet having a perimeter portion that is engaged by the fabric gripping member of the perimeter frame, the tensioned fabric sheet located below the acoustic ceiling panels and covering the central opening.
  • a ceiling system including a ceiling structure suspended in an interior space.
  • the ceiling structure includes: a perimeter frame defining a central opening, the perimeter frame including: a first fabric gripping member; and a second fabric gripping member; a first tensioned fabric sheet having a perimeter portion that is engaged by the first fabric gripping member of the perimeter frame, the first tensioned fabric sheet covering the central opening; and. a second tensioned fabric sheet having a perimeter portion that is engaged by the second fabric gripping member of the perimeter frame, the second tensioned fabric overlying the first tensioned fabric.
  • a ceiling system including a ceiling structure suspended in an interior space.
  • the ceiling structure includes a perimeter frame defining a central opening, the perimeter frame including: a fabric gripping member; a track comprising a first retaining element configured to couple the fabric gripping member to the track and a second retaining element configured to couple the fabric gripping member to the track; and the fabric gripping member coupled to the second retaining element; and a tensioned fabric sheet having a perimeter portion that is engaged by the fabric gripping member of the perimeter frame, the tensioned fabric covering the central opening.
  • a fabric gripping apparatus includes: an anchor plate; a gripping portion including: a first wall extending outward from a first surface of the anchor plate; a second wall extending outward from the first surface of the anchor plate and extending substantially orthogonal to the anchor plate along a first reference plane, the second wall comprising a base section and a first gripping section having a plurality of first teeth; a fabric collection cavity formed between the first wall and the base section of the second wall; a gripping plate connected to a distal end of the first wall, the gripping plate comprising a lever section and a second gripping section having a plurality of second teeth; and the gripping plate positioned so that the second teeth oppose the first teeth to form an access slot into the fabric collection cavity, the gripping plate oriented so that the lever section of the gripping plate diverges from the first reference plane with distance from the anchor plate.
  • ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range.
  • any reference to direction or orientation is merely intended for convenience of description and is not intended in any way to limit the scope of the present invention.
  • Relative terms such as “lower,” “upper,” “horizontal,” “vertical,”, “above,” “below,” “up,” “down,” “top” and “bottom” as well as derivative thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description only and do not require that the apparatus be constructed or operated in a particular orientation.
  • FIG. 1 illustrates a ceiling system 11 including a plurality of ceiling structures 13 installed within an interior space 15.
  • Each ceiling structure 13 is suspended from an overhead structure 17 of the interior space 15 by a plurality of suspension members 19, such that each celling structure 13 is spaced apart from the overhead structure 17 and suspended in a free-hanging manner below the overhead structure 17.
  • the overhead structure 17 may be a beam or other structural member of the interior space 15, and the suspension members 19 may be wires, cables, tie rods, hangers, struts, and the like.
  • Each ceiling structure 13 is suspended from the overhead structure 17 of the interior space 15 without being directly affixed to any wall 21 of the interior space 15.
  • Each ceiling structure 13 is also not directly affixed to any of the other ceiling structures 13.
  • one or more ceiling structures 13 may be suspended within the interior space 15 solely by the suspension members 19. Although each of the ceiling structures 13 are shown as being parallel to the floor 23 of the interior space 15 and to each other, in certain embodiments one or more of the ceiling structures 13 may be suspended so that it is non-parallel to the floor 23 and/or non-parallel to one or more of the other ceiling structures 13.
  • one or more of the celling structures 13 may be suspended within the interior space 15 so as to be partially or entirely spaced from all walls 21 of the interior space 15.
  • any one or more of the ceiling structures 13 may be directly coupled to one or more of the walls or one of the other ceiling structures 13.
  • directly coupling any one or more of the ceiling structures 13 to one or more of the walls or to one or more of the other ceiling structures 13 may be done to create differences in the overall visual appearance of the interior space 15.
  • only one ceiling structure 13 may be included in an interior space, such that the one ceiling structure 13 spans from wall to wall of the interior space, thereby enabling uniform acoustic performance across the interior space, while at the same time allowing the presentation of a desired seamless visual appearance that is decoupled from the acoustic performance of the ceiling structure 13.
  • the ceiling system 11 may include one or more ceiling structures 13 installed in a space which includes an overhead structure 17 and is not bounded by walls. Such an embodiment is possible because walls are not required to provide structural support to the ceiling structures 13 that form the ceiling system 11.
  • FIG. 2 a bottom perspective view of a ceiling structure 13 is shown.
  • the ceiling structure 13 includes a perimeter frame 31 forming a side periphery 33 of the ceiling structure 13 and a tensioned fabric sheet 35 coupled to the perimeter frame 31 to form a bottom face 37 of the ceiling structure 13.
  • the tensioned fabric sheet 35 has a perimeter portion secured to the perimeter frame 31 along the entire periphery of the bottom face 37 of the ceiling structure 13 so that the tensioned fabric sheet 35 presents a seamless visual appearance. In the embodiment shown, only a small perimeter portion of the bottom face 37 is not covered by the tensioned fabric sheet 35.
  • the side periphery 33 of the ceiling structure 13 remains exposed to view, not according to the claimed subject-matter.
  • the side periphery 33 of the ceiling structure 13 formed by the perimeter frame 31 is unbroken by holes or seams, with the exception of at the corners of the perimeter frame 31, so that the side periphery 33 also presents a seamless visual appearance.
  • FIG. 3 A top perspective view of the ceiling structure 13 is shown in FIG. 3 .
  • the perimeter frame 31 forms a central opening 41
  • a support grid 43 having a plurality of intersecting struts 45, forming a plurality of grid openings 47, is coupled to the perimeter frame 31 within the central opening 41.
  • the manner in which the support grid 43 is coupled to the perimeter frame 31 is a matter of design choice, and is not to be limiting of the invention.
  • a plurality of acoustic ceiling panels 49 are mounted to the support grid 43, with each acoustic ceiling panel 49 being disposed in one of the grid openings 47.
  • the perimeter frame 31 is shown as being a square and the support grid 43 is shown as a rectangular grid.
  • the perimeter frame 31 may be formed in other shapes, and similarly, the support grid may have other grid patterns, such as square, hexagonal, and the like.
  • the tensioned fabric sheet 35 spans across the entire central opening 41 of the perimeter frame 31, the appearance of the acoustic ceiling panels 49 may be entirely irrelevant because they are blocked from view by the tensioned fabric sheet 35. Therefore the acoustic performance of the acoustic ceiling panels 49, in certain embodiments, may be improved because there is no need for the acoustic ceiling panels 49 to strike a balance between acoustic performance and aesthetic appearance.
  • the support grid 43 in addition to supporting the acoustic ceiling panels 49, also serves as a support assembly for the ceiling structure 13.
  • the suspension members 19 have a first end 51 coupled to the support grid 43 and a second end 53 that is configured to couple to the overhead structure 17 of the interior space 15.
  • the acoustic ceiling panels 49 may be omitted, such that the support grid 43 may have a structure that need not be configured to support the acoustic ceiling panels 49.
  • the support grid 43, as a support assembly need not be a grid at all, but rather configured purely as a support assembly for the ceiling structure 13.
  • the perimeter frame 31 includes elongated frame members 61 and elongated grip bars 63 coupled to each elongated frame member 61.
  • Each elongated frame member 61 is coupled to an adjacent elongated frame member 61 by corner brackets 65, so that when the elongated frame members 61 are all coupled together, the perimeter frame 31 having the central opening 41 is formed.
  • the elongated frame members 61 With the elongated frame members 61 coupled to form the perimeter frame 31, the elongated frame members 61 collectively form a track 67 that circumscribes the central opening 41.
  • the elongated grip bars 63 are coupled to the elongated frame members 61, so that they are also effectively coupled to the track 67, to circumscribe the central opening 41 and collectively form a fabric gripping member 69.
  • the perimeter portion of the tensioned fabric sheet 35 is coupled to each of the elongated grip bars 63 so that the tensioned fabric sheet 35 is secured to the perimeter frame 31 along the entire periphery of the bottom face 37 of the ceiling structure 13, thereby covering the central opening 41.
  • the elongated grip bars 63 serve to maintain the tensioned fabric sheet 35 in a tensioned state across the central opening 41.
  • the ceiling structure 13 may include more than one fabric gripping member 69.
  • the fabric gripping member 69 may be coupled to the track 67 in any desired location.
  • the support grid 43 is formed from the plurality of intersecting struts 45, which include longitudinal strut members 71 (e.g. main beams) and lateral strut members 73 (e.g. cross tees).
  • the longitudinal strut members 71 may be referred to as main beams because in certain embodiments the suspension members 19 may couple to these strut members alone to providing suspension support for the entire ceiling structure 13.
  • the lateral strut members 73 may be referred to as cross tees because these strut members are generally, but not necessarily, supported only by the longitudinal strut members 71 without having suspension members 19 securing them to the overhead structure.
  • the longitudinal and lateral strut members 71, 73 are elongated in shape having a length greater than their respective width (e.g. at least twice), and in various embodiments lengths substantially greater than their widths (e.g. 3 times or more).
  • the longitudinal strut members 71 may have a substantially greater length than the lateral strut members 73, such that the longitudinal strut members 71 form "runners" or “rails" which are maintained in a substantially parallel spaced apart relationship by the lateral strut members 73.
  • the lateral strut members 73 may be permanently or detachably coupled to and between adjacent (but spaced apart) longitudinal strut members 71 at appropriate intervals.
  • the manner in which the lateral strut members 73 are coupled to the longitudinal strut members 71 is a matter of design choice, and is not to be limiting of the invention.
  • the support grid 43 also includes support members 75 which couple to multiple ones of adjacent (but spaced apart) longitudinal strut members 71, and the first end 51 of the suspension members 19 may be coupled to the support members 75.
  • the support members 75 may also be coupled to adjacent lateral strut members 73 to provide greater stability in the lateral direction.
  • every longitudinal strut member 71 need not be directly coupled to one of the suspension members 19.
  • the combination of the interconnected longitudinal and lateral strut members 71, 73 and the support members 75 helps provide strength and stability to the ceiling structure 13.
  • the longitudinal and lateral strut members 71, 73 intersect to form an array of grid openings 47 which receive and are closed by ceiling panels 49 when positioned within the grid openings 47.
  • the longitudinal and lateral strut members 71, 73 may be arranged in an orthogonal pattern to intersect, respectively, at right angles (i.e., perpendicular) to form grid openings 47 which are rectilinear, such as squares or rectangles (in top plan view).
  • the terminal ends 81 of the lateral strut members 73 that couple to the longitudinal strut members 71 have end connections configured for permanent or detachable connection to the longitudinal strut members 71 at right angles as part of forming the rectilinear grid pattern.
  • the lateral strut members 73 may be coupled to the longitudinal strut members 71 through use of a permanent connection such as, without limitation, welding, soldering, and the like, or through use of a detachable connection such as, without limitation, clips, brackets, threaded fasteners, interlocking tabs/slots, and the like.

  • the terminal ends 87 of the longitudinal strut members 71 have end connections configured for permanent or detachable end-to-end connection to the elongated frame members 61 to form the continuous spans of the main beams.
  • the longitudinal strut members 71 may likewise be coupled to the elongated frame members 61 through the use of the support bracket 85.
  • the longitudinal strut members 71 may be coupled to the elongated frame members 61 through the use of any detachable connection such as, without limitation, clips, brackets, threaded fasteners, interlocking tabs/slots, and the like.
