(Cl. 52-495) ABSTRACT OF THE DISCLOSURE A ceiling panel construction including mounting beams extending outwardly from a wall surface having laterally extending supporting edges and flexible panels resting on said supporting edges and stiffened by tensioning members which span the panels.

' This invention relates to a panel construction for covering wall-like surfaces.

The common practice in t-he construction art today is the provision -of false or suspended ceiling either to mask and/ or lower extremely high and perhaps unsightly older ceilings or to mask heating ducts, light xt-ures, wiring and the like, suspended from ceilings in new construction. One common form of ceiling suspension is the utilization of a light-weight, grid-like, framework suspended from the existing ceiling by wires, cables, or the like. Panels having peripheral lips are simply thrust into the framework and are held therein with the lips of the panels resting upon flanges formed on the beams of the grid-like framework. However, in lpresent practice, the size and material of the panels is limited. The panels must be formed of relatively rigid materials capable of supporting their own weight and usually not greater in dimension than two feet by four feet.

It is therefore a primary object of this invention to provide a new and improved panel construction for ceilings.

Still another object of this invention is to provide a new and improved panel construction for ceilings which permits the use of panels of increased size, thereby reducing the amount and cost of labor and supporting material involved in installing such a ceiling.

Yet another object of this invention is to provide a new and improved .panel construction for ceilings which may also perform the function of serving as a supplementary duct or conduit for carrying Ventilating components, light fixtures, or electrical wiring or the like.

A funther object of this invention is to provide a new and improved panel construction for ceilings permitting t-he use of extremely thin panel material and further permitting the use of materials previously considered unsuitable for use as ceiling panels.

Other objects, features and advantages of the present invention will be apparent from the following description of the preferred embodiments illustrated in the accompanying drawings, in which:

IFIGURE l is a sectional view showing the ceiling panel units of this invention positioned on bea-m members suspended from a ceiling;

Referring now to the drawings, the panel construction 10 of this invention is intended for use in suspension from a ceiling 12 to create a false or suspended ceiling between the walls 14 of a structure. To assist in holding the panel construction of this invention, a plurality of gene-rally T- shaped, light-weight beams 16 having panel supporting surfaces or flanges 16a are suspended substantially parallel to each other from the ceiling 12 -by means of a wire or cable 18 which is tied at one end through an opening 1-6b in the beam and is secured at the other end to a hook 20 fastened in the ceiling 12.

The panel construction 10 of this invention includes a main ceiling panel 22 which is a substantially flat, rectangular, elongate member. The material used in forming the panel 22 may be one of several common building materials such as wood laminates, aluminum, many well-known librous acoustical materials, plastics, pressed paperboard products or the like. Depending upon the intended function of the panel, it may be opaque, transparent, or translucent and may be decorated with a pattern which may be printed or embossed thereon. The lpanel is preferably relatively thin so that it normally would sag or would be unable to support its own weight (as shown in dotted outline in FIGURE 1) if inserted between the beams.

The panel 22 is provided with locking means such as small inwardly returned lips 22a formed along the two parallel long side edges of the panel, preferably by merely bending t-he panel edges inwardly upon the panel. The width of the panel between the lips is slightly less than the interior dimension between the beams 16. The lips 22a provide a means for engaging a tensioning member or bowing member 24. y

The tensioning member may be a flat sheet of relatively inexpensive material such as galvanized steel or the like and preferably has a width which is greater than the 4width of the panel. The tensioning member may be Very short as compared to the length of the-panel or may be coextensive in length therewith.

When the tensioning members are mounted to the panels so that each end is positioned under the lips 22a of the panel, the increased dimension of the tensioning members forces the llat face 22h of the panel into a relasubstantially smooth configuration to strengthen the panels across the width thereof. This not only gives a smo-oth facial configuration to the panels, but it also per-mits the Kpanels to be securely held between the beams merely by placing the panels so that the panel edges rest upon the flanges 16a. For convenience, the tensioning members 24 may be installed in the panel members 22 prior to the installation of the panels between the beams 16. After the tensioning member is inserted in the panel, the panel may I'be substantially llat across the bottom (as shown in the drawings) or slightly bowed. In either event, the insertion of the tensioning member will lend sufficient `rigidity to the panel so that it may be supported in the manner illustrated.

The installation of these panel units is relatively simple. All that need to be -done is to insert the assembled panel unit between the beams by slightly cocking or angling the panel unit between the beams and lifting the panel unit above the flanges 16a. Then the panels need be simply straightened so that they are substantially planar with the ceiling and floor and dropped upon the flanges of the beams where they will be securely held in a finished assembled position. Well-known means, such as taping, may be employed to mask the joint between the panels and flanges, if desired.

As shown in FIGURE 1, a light lixture 26 may be suspended from the ceiling 12 Iby suspension means 26a so that it hangs between the tensioning members 24. In this instance, the panel 22 could be made of a translucent material or have a translucent portion so that the illumination from the light fixture would shine through the ceiling panel.

Also, as shown in the extreme right of FIGURE `1, the panel 22, if made of a suitable material, may 'be comrbined Wi-th a tensioning member 28 which is coextensive in length with the paneling member 22 to serve as a duct. Suitable connections may be made between the duct and the heating or Ventilating system at spaced points along the length of the suspended panel structure. The resultant continuous hollow `duct can be easily sealed at spaced points along the length thereof so that it could adequately serve as a heating or Ventilating duct. Furthermore, such a duct can be used to conceal .and carry lighting, wiring or other service conduits. In addition, a tensioning member 28 which is coextensive in length with the pan-el 22 may be used as the mounting means and reliector for elongate light tubes such as fluorescent lights or the like.

'A modified form of -this invention is shown in FIG- URES IEl through wherein a panel structure 30 is utilized. Here the ceiling 12 is provided with spaced beams 32, such as the ceiling joists of a typical basement structure. In such a situation, T-bars 34 may Ibe mounted on the beams 32 by suitable fastening means, such `as screws 36, so that the T-bars 34 extend generally perpendicular to the -beams and parallel to each other. These T-bars 34 may be continuous beams '(as shown in [FIGURE 4) or may be in the form of individual units secured to each beam 32. The T-bars 34 are provided with first and

second lingers

38 and 39 at the termina-l ends which form a panel receiving notch 40 therebetween. The lo-wermost finger 39 is preferably shorter than the upper finger 38. Panels intended for use with this embodiment are also so relatively light-weight and thin that they could not support their own weight if placed between two anges of ordinary spaced *beams such as those shown in FIGURES 1-3. However, the T-bars 34 have their ngers rformed so that the notches 40 extend slightly upwardly as well as outwardly and the panel 42 has a width which is greater than the distance betwen the center lines of the T- bars so that a light-weight elongate panel 42 may be held between the bars by pushing the -panel up between the bars until the edges of the panel are received in the notches. In this manner, the panel is held in a bowed condition and maintains its smooth configuration in place in the ceiling.

rIlhe panels

22 or 42 may be pre-formed in a bowed condition and mounted on the supports with the concave side facing downwardly, eliminating the need for any tensioning members. As the panels began to sag, t-he side edges would spread outwardly to a point -where they abutted the support, thereby preventing further sagging and spreading and rmly holding the panel in place.

Cil

This invention provides a ceiling panel construction which may be assembled with the use of materials previously thought to be unsuited ffor this purpose either due to the liexible nature or relative thinness of the material or a combination `of both. The ceiling panel construction of this invention may also serve a utilitarian as well as decorative function in that it may be utilized as a part of a heating and Ventilating system, may serve as a lighting fixture, or may be used to carry suitable pipe conduits commonly mounted to the ceiling in the space between the ceiling and the suspended or false ceiling.

The foregoing detailed description has been given for clearness or understanding only, and no unnecessary limitations should be understood therefrom, as some modifications may be obvious to those skilled in the art.
