Another object of the invention isto provide ceiling panels which are hollow and which may be assembled with a minimum of tools.

12; FIG. 14 shows a side view of a means for joining a plurality of panels perpendicular to each other at their point of intersection; and
FIG. 15 is a top view of the structure of FIG. 14.
Referring first of all to FIGS. 4 and 5, generally indicated by the numeral 1 the hollow panels of this invention comprise two identical facing sheets 2 and an intermediate connecting member 4 for holding the facing sheets 2 in a relatively fixed spaced apart position.
The opposite edges of the facing sheets 2 have flanges 3 terminating in inturned lips 3' which resiliently grip the ends 10 and 10 of the arms 5 and 5 respectively on the opposite ends of the connecting member 4. The central web portion of the connecting member 4 has an opening 6, which is described more fully hereinafter.
In the preferred embodiment, the immediate member 4 is an extruded material of metal, plastic or the like with extruded aluminum being presently preferred. It will be appreciated, however, that other'materials such as wood, plastic and other synthetics may be utilized. The facing sheets 2 may be extruded or rolled sheet material 'of many varieties including metal and is preferably of a resilient or spring-like nature such that the inturned lips 3 may be sprung apart to pass over the points 10 and 10 of the intermediate member 4.
The facing sheets 2 are, accordingly, sprung into place and held there by the inherent resiliency of the material.
In the preferred embodiment, the edges of the opposing flanges 3 of the two facing sheets 2 of the panel are spaced apart leaving a longitudinal slot 7 along each of the longitudinal edges of the panel.
Alongthe lowerexposed longitudinal edge of the panel 1 is provided a cover 'strip' or cap 8 held in place by the spring clip 9 having lateral projections 9"to support the inwardly directed flanges 8' of the strip 8.
Spaced, upwardly directed legs 9" are sprung into place in the slot 7 to hold the strip 8 in place.
As shown in FIGS. 6 and 7, two panels I, may be secured edge-to-edge along their longitudinal edges by means of spring clip 11. Spring clip 11 is generally'U- shaped and has two substantially parallel legs 12' each of which includes a gripping portion 13, which engages the member 4 on the side opposite to the bight 12' of the U-shaped member 11. The legs 12 with their gripping portions 13 pass through the openings 6 in connecting members 4 of two adjacent panels 1.
It will be appreciated that while only one connecting member 4 is shown in FIGS. 4 7, there are at least two of such interconnecting members one adjacent each end of the panel 1. Intermediate connecting members 4 may be utilized as desired or required to'lend additional rigidity to the panel.
With reference to FIG. 1, there is shown a grid-like arrangement for supporting the panels from an overhead ceiling structure including beams, overhead fixed floor-ceiling combinations'and the like. The panels are supported from such overhead structure by means of members 14 in a manner described in more detail hereinafter. As shown in FIG. 1, the panel 1' extending from left to right in the figure is abutted by the ends of a plurality of panels I.
FIG. 2 shows a grid system of panels like that in'FlG. I excepting only that there are two sets of panels I joined together along their longitudinal edges asshown in FIGS. 6 & 7 and two sets of panels 1 arranged vertically with respect to each other in the same manner. It will be appreciated that while only two such vertically aligned series of panels is shown in FIG. 2 there may be three or more such panels arranged in edge-to-edge relationship along their longitudinal edges.
FIG. 3 shows an arrangement in which there is a combination of single panels and a series of double panels thus combining FIGS. I and 2.
The panels I are suspended from the ceiling by means of a rod 14 (See FIGS. 14 & 15). threaded into a hub 18 extending upwardly from a cross-shaped member 15. The member 15 is secured at the intersection of panels 1 by means of screws 17 passing through slots 17' in the ends of the arms of the member 15 and through the slots 7 in the panels I. A clamping member 16 is positioned within the hollow panels 1 to engage the underside of flanges 3 of the facing sheets 2. The screws 17 threadly engage and draw the clamping member 16 tight against flanges 3. It will be appreciated that while the panels are secured by means of threaded rods 14 other means may be used including. wire, cable and the like designed to engage the member 15 or to pass through the hub 18 into the interior of the panels 1 to be fixed appropriately there.
With respect to slot 7, this slot may be so designed, if desired, as to be closed when the panel is assembled. However, in such circumstances other means must be provided to hold the cover strip 8 such as spaced openings and for accepting the screws 17.
FIGS. 8 and 11 show the intermediate connecting member 4 also shown in use in FIGS. 4 7. It will be appreciated that the opening 6 is located adjacent one end of the intermediate member 4, and as such, care must be taken during assembly of two adjacent panels in order to be certain that the openings 6 of the members 4 of the two adjacent panels are toward each other as shown in FIGS. 6 and 7. To overcome this requirement two openings 6 are provided in the intermediate connecting member 4' shown in FIG. 9. ln this manner by use of the intermediate connecting member 4', either edge of a completed panel will mate with either edge of an adjacent panel 1, there being an opening 6' on both ends of the intermediate member 4. Similarly, in H6. 10 a single long slot 6" is provided in the intermediate member 4 thus accomplishing the same purpose as the dual openings 6' in the member 4.
As shown in FIG. 8, the upper and lower arms 5 and 5 are somewhat differently shaped, either shape being satisfactory. Alternately, the upper and lower arms may be shaped the same as in FIG. 9 or may have a still different shape as shown at 5" at the bottom in FIG. 10.
It will be appreciated that assembly of the panels can be accomplished without any particular use of tools.
The facing sheet 2 for one side may be placed on the floor or bench with its flanges 3 upstanding. The connecting member 4 may then be snapped into place with the end portions 10 and 10 engaging between the lips 3 of the upstanding flanges 3. The other facing member 2 may then be snapped in place thereover with its flanges 3 extending downwardly toward the companion flanges 3 of the first facing sheet 2. Thus, both facing sheets 2 are sprung into place due to the springlike or resilient nature of the material selected for their manufacture. It will be appreciated that the length of the member 4 including its terminal portion 10 and 10 is dimensioned to achieve proper frictional engagement with the spring-like flanges 3 of the facing sheets 2.
If desired. panels 1 may be joined in abutting end-toend relationship by means of a connecting member 4 of suitable width inserted partly in one of such two adjacent panels and partly in the other.
I claim:
1. An elongated panel comprising two elongated facing sheets, at least one connecting member for holding said sheets in substantially parallel planes on opposite sides of said connecting member, a pair of opposed flanges along opposite edges of each of said sheets, the opposed flanges of each of said sheets being springable apart to receive said connecting member therebetween and to retain said sheets in place on opposite sides thereof, the flanges of each of said sheets being spaced from the flanges of the other of said sheets to define a slot along two opposite edges of said panel, each of the opposite ends of said connecting member having an opening therein and said flanges having inturned lips engaging said connecting member at said openings, said connecting member being a substantially rigid single unitary piece including:
