United States Patent CEILING COVERING AND APPARATUS FOR SUSPENDMG SAME George L. Ely, Hopkinton, Mass, assignor, by mesne assignments, to Sylvania Electric Products Inc., New York, N. Y., a corporation of Massachusetts Application February 15, 1949, Serial No. 76,496

3 Claims. (Cl. 189-88) This invention relates to apparatus for covering ceilings, more particularly to a novel suspension means for ceiling panels by means of which the decorative effect of a ceiling may readily be changed and panels may conveniently be adjusted either vertically or horizontally.

Frequently in old buildings, the ceilings of the rooms are rendered extremely unsightly by the presence of numerous fixtures of various kinds, such as sprinkler pipes and air ducts; likewise in the case of newly constructed buildings, it is a major problem to devise means for concealing necessary piping fixtures, as well as air conditioning systems and the like. In the past one methodhas been to provide large between-spaces in the floors to accommodate such pipes. Another expedient has been to provide permanently installed panels arrayed below a conventional ceiling with the individual panels cemented together or otherwise permanently joined. Both of these methods have the disadvantages of being extremely costly and not at all adapted to adjustment once they have been installed. Furthermore, since the ceilings of many older buildings are rough and uneven the installation of such ceiling coverings entails costly architectural calculation and fabrication to attain an acceptable finished appearance.

Permanent ceilings have the further disadvantage of being poorly adapted to the accommodation of variable combinations of lighting fixtures or acoustic absorption members. major operation to alter the lighting system to correspond with changes in the lighting requirements within the room. Furthermore the installation or removal of sound absorbing equipment generally entails a complete renovation of the ceiling. Another disadvantage experienced with conventional ceiling coverings is the maintenance problem. Due to the permanent nature of the panel suspension it is practically impossible to enter the space between conventional coverings and ceilings for repairs or cleaning.

Therefore it is an object of my invention to provide a ceiling covering of attractive appearance which may not only be useful in covering the unsightly pipes, ducts and fixtures of conventional ceilings but also be readily adapt able for adjustment or alteration.

it is a further object of my invention to provide a ceiling covering fully capable of providing passage for ducts, pipes, fixtures and the like so that the floors of newly constructed buildings may be constructed as simple weight-supporting members without regard to the provision of space for ducts, wires, pipes, or the like.

An additional object of my invention is to provide means for suspending panels from a conventional ceiling which will be readily adjustable horizontally and vertically and also permit ready interchange of the said panels.

in the accomplishment of these objects, I employ, in a preferred embodiment of my invention, symmetrically matched ceiling panels and suspend them from the conventional ceiling joists by depending hangers. The panels Once they have been installed, it becomes a align adjacent to each other to form a continuous ceiling covering but have clipped or indented corners providing small openings through which the hangers pass.

It is a feature of my invention that the hangers support the weight of the panels from below without being rigidly secured to the panels. This is done by means of a support ring which extends laterally from the hangers under the adjacent corners of the panels. Thus, the panels may readily be removed by simply lifting the panels off the support rings, tilting the panels and lowering them through the panel space.

It is an additional feature of my invention that the panels are held firmly against lateral relative motion by upstanding lugs on the retaining rings. The lugs fit into appropriately located apertures in the panels adjacent to the panel corners, and hold the panels together. However, the lugs do not prevent independent panels from being lifted for removal or change.

It is an additional feature of my invention that the hangers are slidably connected to the ceiling joists by means of channel guide bars for horizontal adjustment.

Still another feature of my invention lies in the provision of a threaded member connecting the lower part of the hanger to the upper part of the hanger for vertical adjustment. The said lower part of the hanger extends below the panel support ring and is provided with a laterally extending flange or shoulder upon which the support ring rests. The ring, however, is independent from the hanger which may be rotated from below to raise or lower the panel corners, without disruption of the panels.

Further objects and features of my invention will best be understood and appreciated from a detailed description of preferred embodiments thereof, selected for the purposes of illustration, and shown in the accompanying drawings in which:

Fig. 10 is a plan view of the panel support ring shown in Fig. 8, and

Fig. 11 is a sectional view in side elevation along the lines 11-11 of Fig. 10.

In a preferred embodiment of my invention I employ channeled guide bars 10 secured to the joists or structural members of a conventional ceiling (not shown). The guides 10 are preferably of tubular metal construction having in their bottom a longitudinal channel opening 12. Suspended by the guides 10 are a plurality of hangers including pendants or rods 14 and flanged brackets 26. The rods 14 are threaded at their upper ends to receive flanged nuts 16 which serve to retain the pendants 14' within the guides 10. The flanged nuts 16 extend laterally across the openings 12 of the guides 10 and when secured to the upper ends of the rods 14 prevent the rods 14 from dropping out of the guides 10, but at the same time permit horizontal movement of the rods 14 along the longitudinal axis of the guides 10. p

The lower ends of .therods 14 are threaded and conneat .to appropriately tapped upstanding shanks 28 .of .the brackets 26. The brackets .26 protrude below the ceiling panelsand are provided with a laterally extending flange 2.7 ".Whlfih serves to support panel support rings A as will be described "below. The :brac'kets 26 may :be adjusted vertically by simply iturning them from .helow, .and \may -be zlocked imposition .of adjustment .by lack nuts 29 on the rods 14 bearing against the upstandingshanks 28.

Various :types of ceiling panels may 'be employed and .are indicated generally in Fig. 3 at 18, 20, 22 .and 24. The :panel 518 represents what is generally known in the trade as .a :louvre panel, consisting in .a continuous recztangular :peripheral :frame member .30 constructedof sheet metal and disposed on edge. Secured to :the frame '30 is ;a series of sheet .metal strips .or lattices I32lsimilar1to the side-frame :30 .but notched at intervals ato receive similar strips '35 :laid at right :angles to the strips .32 to :form .a .crosslattice. Each .of the'lattices Bland 35 are provided --with short :flanges .33 bent at right angles to the .lattices .and spot welded'to the frame '30 for the purposes .of supporting the said lattices .32 and .35 within the frame .30.

*The panels 18 are provided with oblique .corners for the purpose of=accommodatingthe hangers and retaining rings 40 as will be further described below.

The .panel 20 is .of rectangular shape withsimilardi- :mensions to the :panel 18 and may be constructed of plywood or other suitably .obdurate and opaque substance. -Each of the rcorners of the said panel .20 .is obliquely clipped and further provided with a small'perforation 34.

The ipanellti may the .used to supportacentrally .mounted luminaire indicated generally at 36 of conventional .construction providinga spotlight or screened :lighti-ng as desired.

The panel 22 is of similar construction to the panel .20, including perforations 34, but may preferably be :made of --a translucent material, such ,as Lucite and colored with various shades and hues as desired.

The;panel-24 is opaque and ofsimilar construction-and shape to the panel 20, including perforations 34, :and may preferably mount upon its .underssurface a-sound absorbing member 35.

lt will belevident from the structure -.-thus.describe d that tween their adjacent corners and that the shank 28 of the bracket 26 extends-upwardthrough this opening. For the purposes of supportingthe corners of thesaidtpanels, and :of prevening random lateral movement of .the same, I provide a support ring .40 having upstanding lugs 42. The

support ring .10 is independent from the bracket 26 'but vfits around the shank .28 of the bracket 26 and rests upon the flange 27. The upstanding lugs 42 of the retaining --ringr40 fit-into .thenotches 34 of the panels 20,;22 and'24,

and fit inside of the corners of the frame .30 of the louvretype :panel 18. The flange .27 .of the \bracket 26 may be formed in the shape of a roughly rectangular, four cornered star, extending laterally underathe corners of the panels. The upper surface of the flange 2. 7 is provided ..with a shallow recess .44 for the purpose of receiving the retaining ring 40 and to allow the outer ends of the-flange 30 to set upwardly adjacent to the .under surface of the panels.

Another hanger :for the ceilingcovering of .my invention is illustrated .in Figs. 8, 9, .10 and 11 and includesadouble angle link 5.0, 2. depending rod 60 and a panel support -.ring.62. The .link v50 -.isirnade of .metal plate andds bent to form a verticalside wall 52, an upper horizontal flange 4 screw head 64 for the purpose of suspending the support .uug iz and fo rotatin the rod 11 .tc radi a adjustmen The support ring 62 fitsaround the rod 60 and rests upon the laterally extending shoulder of the screw head 64. The support ring 62 is similar to the support ring in its function of supporting the panels, and it is likewise provided with upstandi g lugsfifi which corresp n to the lugs 42 of the ringfit). However, since the screw head 58 is relatively small and the under surface of the support ring 62 will .be exposed to vi w :beneath the ceilingpanels, the support ring .62 ;is @formed .in .the shape of a four cornered star as illustrated in Fig. 10 for decorative purposes.

It will be seen that the hanger -illustrated in Figs. 8, 9, l0 and 11 may conveniently .be :adjusted vertically by turning the rod 60 with a screw driver below the panels.
