Definitions

  • the invention relates to a ceiling lining, in particular for a suspended ceiling, where thin-walled elongated lamellae with their longitudinal edges turned over ininwardly are arranged on preferably mushroom-shaped lugs of transverse beams of channel-shaped or nearly channel-shaped cross-section so that the lamellae can be snapped on the lugs.
  • the lamellae of these linings have usually a flat centre part, for technological, aesthetic, and acousitc reasons.
  • the linings with lamellae which can snap in position have the disadvantage that sometimes stresses remain in the material after the assembling operation, on account of the snap action, with the result that the fiat centre pieces of the lamellae are deformed. These deformations are clearly visible, even though they are only slight, and mar the aesthetic effect.
  • permanent damage to the thin-walled longitudinal edges of the lamellae often remains after snapping them around the narrow, preferably mushroom-shaped lugs of the beams.
  • each longitudinal edge of the lamellae comprises a continuous inwardly directed profile on or near its free longitudinal edge with which the lamellae are suspended without stresses from the inner sides of the laterally projecting ends of the mushroom-shaped lugs, the edges of the lugs running parallel to the plane of the ceiling and the lamellae making contact with the lugs only via said profiles.
  • This ceiling lining and/or a lamella for a ceiling lining respectively accordingly relates to a closed ceiling and is characterized in that the lamellae are unsymmetrical and the lugs of the beam are arranged next to each other in such a way that the lamellae overlap each other.
  • each lamella has a preferably flat centre piece merginging along one longitudinal side at an obtuse angle into a plane side surface, the longitudinal edge of which is bent in a parallel or nearly parallel direction back to the centre piece, and the centre piece on the other longitudinal side merges at an obtuse angle into a first side face part, which in turn blends into a second side face part extending parallel or nearly paral- United States Patent 0 lel to the side face of the other centre piece, the longitudinal edge of this second side face part being likewise bent back parallel or nearly parallel to said centre piece.
  • a further advantage of the invention results from another embodiment of the lining and a beam therefor respectively and is characterized in that the beam legs diverge and each leg has at the base of the projections an outwardly extending horizontal part and the lugs are situated in a plane parallel to the plane of the first diverging part of the leg.
  • This beam has the advantage that each pair of lugs provided transversely to the length of the beam and facing each other (with one lug on each leg) are arranged with a greater spacing than with the beams made in the past. This arrangement also reduces the risk of deformation because the forces act in a less concentrated manner on the longitudinal edges of the lamellae.
  • a particularly convenient second advantage of this beam consists in the possibility of placing acoustic sheetlike material on the outwardly extending horizontal parts of the legs. Such material is preferably fixed to the beams by means of adhesive tape.
  • FIG. 1 is a side view of a beam part with the lamellae snapped on it
  • FIG. 2 a side view of a beam part with asymmetrical overlapping lamellae snapped on it
  • FIG. 3 a cross-section through a beam.
  • Beam 1 is a channel section with diverging legs. Each leg has preferably mushroom-shaped lugs 2 arranged with predetermined interspacing. Each lug 2 has projecting ends with an upward fiat part 3 on which the turnedover parts 4 of the lamella 5 rest. The lamellae are suspended from the projecting ends of lug 2 without any stresses and have inside dimensions which are greater than the outside dimensions of the lug so that the lamellae ret on the lug with some play. It is evident that the play between the lugs and the lamellae need only be small.
  • lamellae 6 are of nonsymmetrical design and the lugs are placed more closely together so that the successive lamellae overlap.
  • the recesses above the projecting ends of the lugs are slightly longer than in FIG. 1. This simplifies assembly and removal of the lamellae. Consequently the lamellae can be shifted slightly sideways, after a last lamella has been taken out, so that they can be pulled off the lugs with the aid of a simple tool, and can be replaced and snapped on again by hand.
  • FIG. 3 shows a third embodiment of the beam according to the present invention.
  • the space between the two lugs 2 is much greater than in the beam used so far as shown by dotted lines 2'. Consequently the deforming forces acting on the lamella edges when snapping the lamellae into position are no longer concentrated on a small area.
  • FIG. 3 also shows the additional advantage of mounting sound-absorbing material.
  • a lining for a ceiling in particular a suspended ceiling having thin-walled elongated lamellae with inwardly bent longitudinal marginal portions, arranged on preferably mushroom-shaped lugs of beams having a substantially channel-shaped cross-section and being arranged transversely to said lamellae, said lamellae consisting of a springy material so that they may be snapped onto said lugs, each inwardly bent longitudinal marginal portion having an inwardly directed profiled portion which is substantially parallel to the lining surface and with which the lamellae are loosely suspended without stresses from the inner sides of the laterally projectig ends of the mushroom-shaped lugs, the lamellae being only in contact with said lugs via said inwardly directed profiled portion.
  • a lining for a ceiling in particular a suspended ceiling having thin-walled elongated lamellae with inwardly bent longitudinal marginal portions, arranged on preferably mushroom-shaped lugs of beams having a substantially channel-shaped cross-section and being arranged transversely to said lamellae, said lamellae consisting of springy material so that they may be snapped onto said lugs, each inwardly bent longitudinal marginal portion having an inwardly directed portion which is substantially parallel to the lining surface and which is provided with a curled end portion with which the lamellae are loosely suspended without stresses from the inner sides of the laterally projecting ends of the mushroom-shaped lugs, the lamellae being only in contact with said lugs via said curled end portions.
