Blind-like cladding for ceilings and other purposes ^:

The present invention relates generally to a blind-like construction for ceiling and other purposes, in particular a simplified blind construction, consisting of parallel support runners and rows of light diffusion plates which are designed so that they can be held by neighboring support runners and inserted and removed quickly and easily. ...

Since strong lighting with high intensity light sources such as B. Fluorescent lamps, is possible today, it is

also become necessary the brightness and the glare to regulate this light in order to create comfortable vision. This is achieved by means of light diffusion, such as false Dao & en, © ine blind-like cladding, formed of a variety of light diffusion panels, luminous screens or grids. Each plate can be made of g © ll-shaped

or box-shaped design, consisting of a u-itterwerk of intersecting ribs, which through The floor and ceiling are open. Jas light can go straight through ' the cells formed by the crossed ribs go down, but from a Y / angle from the point of view of this, the ribs of the panels block the light

B _{0 be} square or rectangular units about two feet wide; they can be held edge-to-edge to form a false ceiling of louvre-like construction "extending from wall to" wall all over the room or just part of it the Decfcen-. area. It is desirable that some, if not all of the panels can be easily removed on their own for easy access to the area above this false ceiling, especially the lighting systems »Ss is too _; it is desirable that the connecting and butting lines of ■ - ■ .--. neighboring panels so invisible or unnoticeable. are as possible in order to simulate an unbroken grid arrangement of overlapping ribs over the entire ceiling area o- ^: "'■"■' -. ■■ ■ "': --- -_-' ■ .

The well-known false ceiling constructions or ceiling cladding made of light diffusion plates are not fully "satisfactory. Some of them, although simply constructed, are difficult, time consuming and costly to install and / or leave the individual parts do not move away quickly and easily. Furthermore, often goes light passes between the adjacent panels, leading to division and adversely affecting the continuous uniform appearance of the ceiling. Other constructions are extremely complicated and expensive to manufacture and install ^ and / or the individual parts cannot be moved quickly remove «, in particular the holding devices for the panels complicated, difficult to assemble and bond to the panels, and special tools and skills are required for installation «Some of the common light diffusion plates use" the railless " Construction, which means that they have no visible support runners to have. This is in contrast to the constructions where I-shaped hanging bodies are used or ' The like * The common '' railless "blind systems have a relatively straight bearing between the adjacent plates throughout the distribution body and many narrow gaps between the butting ones

Panels give a line of light, which makes it even Light diffusion is interrupted.

In the known blind suspension systems, the Shark body or runner outside the last ribs of the plates in engagement with protruding parts of the Ribs, which form right angles with the central ribs, and therefore the dimensions of the plate must not exceed a given size when sagging. of the plates should be avoided «Since, in addition, the protruding parts of the ribs during manufacture, Packaging, handling, installation and use subject to damage and bending the suspension points or the points at which the ribs engage with the holding bodies do not maintain their relationship to one another, which makes it difficult makes to insert the protruding ends of the ribs in the slots of the support runners. ,

In addition, the angle causes the light to reflect from curved protrusions or protrusions either a lighter one or a darker one. To adopt tint than that remaining louvre blades what the overall look of the ceiling significantly worsened.

The present invention has for its object to provide a blind construction made of Mehtplatten, the

easy and economical to manufacture and install is, in which the individual plates can be removed quickly and easily, and which gives the impression of a continuous Jaiwsie ceiling or ceiling cladding conveyed due to uniform light diffusion over its entire surface.

The blind-like cladding or blind construction for ceilings or the like of the invention is characterized in that long, parallel at a distance mutually extending support runners, which are designed in this way are that they are carried under a lighting system Ceiling can be held, and fixable light diffusion plates are provided in the support runners each from an incomplete trellis overlapping Ribs of a thickness that is equal to the thickness of the runner, and on two opposite one another Has ends outer ribs, further characterized in that the support runners are designed so that they are in ribs, which Outer ribs overlap, can intervene, the supporting ribs engage at a distance from the end ribs, which is equal to or a multiple of the distance between adjacent ribs is, and the support runners the latticework complete and extend between the edges of the panels, the incomplete trusses of completing at least two adjacent panels *

and means for suspending the support runners at locations which correspond to one edge of a plate, so that the joint a plurality of such plates and runners forms a plane.

The installation of successive panels is often difficult because some of the protruding ribs, formed to overlap the support runners and to come into engagement with them, be bent or twisted, whatever prevents suitable alignment. With the plate according to of the present invention are the suspension points

or the places where the ribs in the support fields intervene within the outer ribs and are therefore not subject to such damage. The relatively fixed points of the suspension points also facilitate the Installation. / -, - ^

The blind-like construction according to the invention has many other advantages which will become more apparent from the following description of an embodiment.

The ends of the rib 30,32 terminate at different points in the longitudinal and transverse directions of a plate, with clans of the neighboring plates and the support runners looking together, to create continuity of the latticework between adjacent panels and prevent them from being straight Pass lines of light between adjacent panels as described earlier.

The embodiment shown and described is one preferred form of the invention, and it is to be understood as that the. Plates 28 can also be rectangular leg without thereby / would deviate from the invention.

In this embodiment there is an arrangement of tongue and Groove is provided, each support runner 26 passing through the tongue 40 and the lut 42 of the adjacent plate 28 crossed over. In this arrangement, the length of the runner 26 exceeds the width of the plate 28 and not only supports adjacent plates 20A, indicated by the tongue and Hat configuration, but also adjoining plates 2OB. In this way, each runner completes the latticework of its "own plus three other panels".

Each of the StU + "" ! Ufer 26 has spaced apart vertical slots 34 (Mg * 2), which extend from its upper edge downwards to approximately its center point. Each support runner 26 also has holes 36 adjacent its upper edge for receiving the lower ends of the suspension means, e.g. B. wires 38 or: the like that hold the runners 26? the upper ends of the suspension means are attached to the ceiling in eyelets (not shown)

Slots 34 in the support runners 26 take the hips 30 of the Plates on, and thereby carry the plates on the support runners.

A blind construction is usually made from a Number of light diffusion plates 28 made.

The ribs 30, 32 are slotted in a manner known per se, so that they interlock and form a latticework of overlapping buttocks. Of course can if it is for aesthetic or 'structural reasons it is desirable to have the lower edges of the ribs with projections or recesses so that the blind construction, seen from below, appears three-dimensional. Indeed, the latticework shown in the figures can

It should also be pointed out that the interlocking serves "to restrict a movement between the -Hippen 30, 32 in the transverse and longitudinal directions. The Ribs 30,32 are made of metal and the slots are ga, nz little shallower than half the height of the ribs 30, 32 that they so that the ribs are snugly fitted together
