Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to wall or ceiling panel construction.

BACKGROUND OF THE INVENTION Problems to be Solved by the Invention A variety of such arrangements are well known and one particular type includes a support structure, which is usually in the form of generally parallel flanks, These side girdles are generally fitted with ears having substantially parallel panels spaced apart from each other by more or less. The panel can have one of several types, one particular type having a center with an upwardly facing rim of arcuate cross section for engaging the flank ears. Includes a nearly flat part of.

Means for Solving the Problems One object of the present invention is to provide a replaceable structure which can be pleasing to the eye and have a decorative effect.

The present invention thus provides a support structure and a plurality of elongated first panels mounted laterally spaced parallel to the support structure such that the outer surfaces of each panel are approximately level with each other. At least one second central portion having a downwardly convex, convexly curved or trapezoidal cross section and having continuous retaining elements extending along respective lateral ends of the central panel portion. A panel and the at least one second panel is fitted between two adjacent first panels such that the retaining element is opposed by the elastic central portion to the two adjacent first panels. Of the at least one second panel fixedly retained in a substantially continuous engagement with the longitudinal edge of the at least one second panel. Outside Projecting from the outer surface of the first panel, and the at least one second panel has a width in the relaxed state that is substantially greater than the spacing between the first panels and the relaxed state of the second panel. It features a panel structure for ceilings, walls, etc., characterized in that the upper surface of the second panel is substantially parallel to the lower surface thereof during transportation and storage so that the panels can be easily assembled.

Such a structure can be relatively simple and inexpensive and the second panel provides an eye-pleasing decorative effect. Such an effect can be enhanced by having the second panel have a resilient central portion of curved or trapezoidal cross section.

The second panel preferably has a width in its relaxed state that is significantly larger than when positioned in the panel array,
Therefore, the resilience produced by this panel is great enough to prevent it from disengaging from the support structure.

The retention element is continuous so that it is in continuous contact with the longitudinal edge of the first panel. This means that the second panel does not tend to warp along its length even if it is supported only by its own elasticity. Therefore, the support is very reliable, and thus a relatively wide second panel can be supported even when the weight is large.

The spacing between the second panels is preferably larger than the width of the second panels themselves so that the second panels occupy a large proportion of the overall width of the ceiling panel structure.

Also, the second panel is used in place of the middle of the series of three first panels so that the spacing width formed thereby is occupied by the second panel and thus the width of one of the first panels. Is also summed with twice the normal spacing between two adjacent two of the first three panels.

The first panels may each have an inwardly directed rim extending inwardly toward the support structure, each rim extending along each longitudinal edge of the first panel,
The continuous retaining elements of the second panel each comprise a groove-like edge shaped to accommodate the shape of the inwardly directed rim.

The support structure also includes side ledges extending substantially perpendicular to the length of the panel, the side ledges having ears that engage the inwardly directed rim of the first panel supporting the second panel. Contains.

In a convenient structure in which all panels are of a rolled form, the inwardly facing rim of the first panel and the retaining elements resembling the grooves of the second panel have an arcuate cross section. .

For ease of transport, the second panel is advantageously shaped so that it can fit together in the relaxed state.

In order to make the present invention easier to understand, the present invention will be described below with reference to the accompanying drawings for the purpose of illustration only.

Embodiments Referring first to FIGS. 1 and 2, the illustrated ceiling panel arrangement includes a conventional support structure including a number of substantially parallel side barbs 10 provided with downwardly facing retaining ears 12. Is equipped with.

The retaining ears are conventionally fitted with a first panel 14 having a flat central portion 16 and an arcuate upwardly facing rim 18. Panel as shown
The width of 14 is shown as A and the spacing between the panels is shown as B. In the preferred construction, it is approximately 3/5 the size of the width A and spacing B of panel 14.

A second panel 20 is mounted between the parallel spaced panels 14. As shown, the second panel is generally bulbous, but can have a shape such as, for example, a curved or trapezoidal cross section. Therefore, the second
The panel 20 includes a central resilient portion 22 provided with a continuous channel-shaped retaining element 24 extending along each side edge. These channel-shaped retaining elements have a curvature that accommodates the curvature of the upwardly facing arcuate rim 18 of the adjacent panel 14.

The second panel 20, in its relaxed state, has a width which is significantly larger than the dimension B, so that during assembly the longitudinal edge of the panel 20 can be bent inward and then released, and thus of the channel shape. The retaining element abuts the arcuate rim 18 and the resilience of the second panel is sufficient to securely retain this panel without further support. The retaining element 24 engages the rim 18 in a substantially continuous manner, so that the central portion 22 has no tendency to warp. Therefore, the retaining element retains a constant cross section along its entire length, giving an eye-pleasing appearance. Therefore, even if the second panel is abruptly locally tapped, it is not necessary to have a very high elasticity for fixing and holding the second panel. Panel 20 can have a number of different initial shapes as shown in FIGS. 3, 4, and 5. Third
In the figure, the central portion 30 is slightly arcuate, but in FIG. 4, the central portion 32 is fairly arcuate. In each case, the spacing between the edges of the channel-shaped holding element 24 is greater than dimension B, so that the edges can be bent inward and then rebounded outward. The structure shown in FIG. 3 has considerably less elasticity than the structure shown in FIG. A trapezoidal central portion 34 is shown in FIG.

However, in either case, the upper surface of the second panel 20 is substantially parallel to the lower surface, so that the second panel 20 can be fitted into each other in the relaxed state to promote the saving of space during transportation.

EFFECTS OF THE INVENTION The structure of the present invention provides an eye-pleasing decorative effect and is also easy to manufacture because all panels can be roll formed, so to speak, between the first panels with the second panel already positioned. It will be appreciated that it provides a structure that is sandwichable and thus easy to assemble. Since the second panel has an outer surface, which in this example is the lower surface beyond the outer surface of the first panel, the elastic central portion 22 is gripped and the portion tightened away from the rim The panel is relatively easy to remove.

Since the spacing between the first panels is quite large, it is rather easy to actually mount the panels on the side.

Although the second panel is shown slightly wider than the first panel in the panel arrangement shown, the second panel can be much wider than the first panel. For example, the center of each of the three first panels can be removed and the second panel spanned by the A + 2B spacing thus formed. The connection formed by the continuous abutment of the retaining element 24 and the rim 18 is relatively strong so that this connection will adequately support such a heavy panel.
