Oct. 2, 1962 J. FISCHER ARRANGEMENT IN WALL AND CEILING PANELLINGS Filed July 25. 1957 Unitcd rates Patent 3,056,476 ARRANGEMENT IN WALL AND CEILING PANELLTNGS Jean Fischer, Sankt Clemens, Denmark Fiied Juiy 25, 1957, Ser. No. 674,189 Claims priority, application Denmark Aug. 1, 1956 Claim. (Cl. 189-86) For sound-deadening wall or ceiling panellings, long rectangular aluminium panels are often preferred to panellings of wood fibre plate or similar material due to the strongly reduced or possibly completely eliminated risk of tire of the aluminium panelling. The mounting of such aluminium panels has, however, hitherto been rather cumbersome, and the mounting work has therefore enhanced the costs of the finished panelling considerably.

The purpose of the invention is to avoid such mounting difliculties or in other words to provide a sounddeadening panelling, in which the mounting of the individual panels can be performed exceedingly easily and quickly, while likewise a dismounting, in case of need, for example to provide access to a sound-quenching layer of material above or behind the panels, will give only little trouble.

Thus, the invention relates to an arrangement in wall or ceiling panellings consisting of generally elongated rectangular panels of thin sheet material such as aluminium plate, the said panels being trough-shaped to be able to accommodate sound-quenching material and being at one end tacked on, or secured in other manner, to the wall or ceiling surface or to a system of rails on the latter while at the other end the panels are carried by the adjacent end, secured to the support, of one or more adjacent panels. According to the invention, the arrangement is characterised in that at their first-mentioned end the panels are provided with a number of attachment lugs projecting from the end and are at their other end provided with one or more projecting carrying lugs engaging between the attachment lugs on the edge of one or more adjacent panels. During the mounting work the carrying lugs on one panel are only inserted between the attachment lugs of a panel already mounted, whereupon the opposite end of the former panel is secured to the ceiling or Wall surface or to its rail system by means of tacks, staples, or similar means.

A panel construction is already known (from German specification No. 11,698) consisting of a number of plates which at one end are double-bent to form a pocket for receiving the slightly oif-set other end of the neighbouring plate. A similar arrangement of assembly may be provided at the other edges of the plate. This known arrangement does not, as is the case with the arrangement according to the invention, produce an intertwinement of the attachment lugs and the carrying lug-s, and the arrangement according to the invention further possesses the advantages that some material is saved and that the manufacture of the plates is made cheaper in that the invention does not require the double bending of one plate edge to form a pocket.

A particular embodiment of the invention is characterised in that the carrying lugs have substantially the same Width as the spacing between the adjacent attachment lugs, in this case, the engagement or intertwinement between the carrying lugs and the attachment lugs will during the mounting automatically ensure a correct placing of a new panel in relation to one or more panels already mounted.

The invention will be more fully explained with reference to the accompanying drawing on which:

FIG. 1 shows an axonometric illustration of part of a ceiling panelling with the arrangement according to the invention during the mounting,

FIG. 2, a vertical section, eg as indicated by the line 11-11 in FIG. 1, through a wooden rail secured to the ceiling and the end portions, carried by the said rail, of two panels, and

FIG. 3, part of a ceiling panelling according to the invention in a modified embodiment, viewed from below.

According to FIG. 1 a number of parallel, equidistant carrying rails 1 of wood are secured to a ceiling surface, not shown, in some appropriate manner, and to these carrying rails elongated, rectangular aluminium panels 2 are secured, each of which has a length corresponding to twice the spacing between the rails 1 and which are mounted in rows in continuation of each other and with the butts staggered in two adjacent rows. The length and width of the individual panels may for example be about 60 cm. and about 10 cm., respectively, and by a simple pressing operation or otherwise they have been given the trough-shape shown on the drawing with a substantially plane bottom and four side walls at right angles to the latter, the said side walls being connected with the bottom through obliquely extending sections, see also FIG. 2.

Each of the panels 2 is at one end provided with three attachment lugs 3 which are tacked on to the overlying carrying rail 1. At the opposite end the panels comprise two projecting carrying lugs 4 which during the mounting, see the panel 2' in FIG. 1, are inserted between the attachment lugs 3 on the panel 2" already mounted and will thus rest on the edge of the end wall of the latter panel. When the panel 2 has been brought into this position, the other end, not shown on the drawing, is secured to the overlying rail 1 by means of tacks 5, FIG. 2, in the attachment lugs at the end of the said panel.

The panels may in a well-known manner be provided with suitable perforations in the bottom, and during the mounting there may in or over the panels be placed a sound-quenching material suited to the conditions.

As will appear from FIG. 1, compare the panel 2 which is being mounted, the panels may prior to the mounting, be slightly curved in their longitudinal direction so that their central parts are above the plane defined by lugs 3 and 4. In doing so, the panels are slightly strained when being mounted because the central parts of the panels are pressed against the overlying carrying rails 1. A particular advantage obtained here by is that, especially in the case of comparatively long panels, a not insignificant saving of material may be obtained owing to an increased rigidity against the bending down of the panels between their supported ends.

The curvature of the panels need only be very slight so that the straightening deformations to which the panels are exposed during the mounting will be slight too.

The panels 6 shown in FIG. 3 may be designed exactly like the panels 2 in FIGS. 1 and 2 with the only difference that the number of carrying lugs at one end of the panel is equal to the number of attachment lugs at the other end of the panel so that the two ends of the panel are in fact identical. As the carrying lugs are located in line with the spacings between the attachment lugs, it does not matter, during the mounting of a panel, whether its attachment lugs or carrying lugs are brought into engagement with a panel already mounted.

FIG. 3 further shows that the panels may be arranged in rows extending at right angles to the longitudinal direction of the panels. The joints between the panels of these rows may lie in extension of each other as indicated in FIG. 3 or may be displaced from row to row.

At the edges of the wall or ceiling surface on which the panelling is arranged, ornamental lists may, if so desired, be provided to support the ends or edges of the panels or to conceal the attachment lugs.

I claim:

A ceiling composed of a plurality of spaced parallel stringers having co-planar lower faces, and a plurality of sheet metal panelling elements arranged end to end in parallel rows, the elements in one row being staggered with respect to those of the adjoining rows, each element extending lengthwise from one stringer across a second stringer to a third stringer, each element comprising an elongated rectangular body portion normally slightly curved in its longitudinal direction with the convex side of the curve facing the stringers, a first pair of bentover flanges extending along the opposite end edges of said body portion and protruding on the convex side thereof, and another pair of bent-over flanges extending along the opposite side edges of said body portion and also protruding on the convex side thereof and engaging against the lower face of the second stringer, said flanges being of equal height, one of the flanges of said first pair of flanges having a plurality of spaced tongues projecting outwardly from the flange in the longitudinal direction of the element, and the other flange of said first pair of flanges having at least one tongue projecting outwardly from the flange in the longitudinal direction of the element and being of a width substantially equal to the space between said plurality of tongues, means securing the tongues of one of the flanges of the first pair directly to the first stringer, the tongues of the other of the flanges of the first pair of the next succeeding end-to-end element engaging beneath such flange, and means securing the tongues of the other of the flanges of the first pair of such succeeding element directly to the stringer, said element being thereby deformed out of its normally curved shape into a flat shape, thereby preventing sagging of the central part of the element, and the lower faces of all the elements being co-planar.
