Definitions

  • the present invention relates to a ceiling panel comprising a top surface, a bottom surface and a surrounding edge extending between the top surface and the bottom surface, wherein at least one cutout extending from the top surface is adapted for engagement with a hanger adapted to be suspended in an overhead structure.
  • WO 2007/012077 discusses a prior art ceiling panel in which a channel of inverted-T configuration is formed in the top face from one edge of the panel to another.
  • a hanger in the form of a profile also having inverted-T configuration is inserted into the channel from the end of the channel and displaced in its longitudinal direction until it is positioned at a distance from the edges of the panel.
  • the hanger is suspended from an overhead structure by means of wire.
  • a channel of inverted-T configuration is rather complicated to provide in a ceiling panel.
  • a channel of inverted-T configuration could be machined by chip removal, such as milling.
  • chip removal such as milling.
  • the integrity of the panel is compromised resulting in reduced strength of the panel.
  • the channel extends through the edges of the panel, the integrity of the panel is further compromised resulting in further reduced strength of the panel.
  • the object of the present invention is to provide a ceiling panel adapted to be suspended in a ceiling, the ceiling panel having improved integrity and strength and being simple to manufacture.
  • the at least one cutout is provided in the form of a first groove and a second groove, in the first groove forms an angle with the top surface of at least approximately 10 degrees, and the second groove forms an angle with the first groove of at least approximately 10 degrees.
  • first and second groove may be machined by simple cutting, for instance by means of a circular saw, whereby only material corresponding to the thickness of the saw blade need to be removed.
  • a hanger having flanges fitting the first groove and the second groove, respectively, may lock mechanically when inserted into the grooves. As very little material need to be removed from the ceiling panel, a much stronger panel may be obtained. Also a better integrity between the hanger and the panel may be obtained, as the flanges of the hanger may fit closely into the grooves obtained by cutting.
  • the second groove forms an angle with the first groove of between 20 and 140 degrees, preferably between 50 and 120 degrees, and more preferred between 80 and 100 degrees.
  • first groove and the second groove are arranged symmetrically about a plane at right angles to the top surface. In this way, both manufacture of the ceiling panel and mounting of the hanger in the panel may be simplified.
  • the first groove and the second groove are positioned at a distance from the edge of the ceiling panel. Thereby, the integrity and consequently the strength of the ceiling panel may be further improved, as the edges of the panel are intact.
  • first groove and the second groove are positioned so that they form parallel, longitudinal openings in the top surface.
  • manufacture of the ceiling panel may be simplified.
  • configuration of the hanger may be simplified in that it may be composed by two longitudinal profiles that are connected after insertion into the respective grooves.
  • the distance between the first and the second groove increases in the direction away from the top surface of the ceiling panel
  • the distance between a first longitudinal opening of the first groove and a second longitudinal opening of the second groove is at least 90 per cent, and preferably approximately 100 per cent, of the extent of the first groove or of the second groove in a direction parallel to the top surface and at right angles to the longitudinal opening of the groove.
  • the present invention further relates to a ceiling panel hanger comprising two flanges for engagement with a cutout in a top surface of a ceiling panel, the flanges being rigidly connectable and adapted for suspension in a ceiling structure.
  • the ceiling panel hanger is characterized in that , in the connected and suspended state, carrying a ceiling panel, the first flange forms an angle with the horizontal of at least approximately 10 degrees, and the second flange forms an angle with the first flange of at least approximately 10 degrees.
  • first and second groove may be machined by simple cutting, for instance by means of a circular saw, whereby only material corresponding to the thickness of the saw blade need to be removed.
  • the hanger may lock mechanically when inserted into the grooves. As very little material need to be removed from the ceiling panel, a much stronger panel may be obtained. Also a better integrity between the hanger and the panel may be obtained, as the flanges of the hanger may fit closely into the grooves obtained by cutting.
  • the second flange forms an angle with the first flange of between 20 and 140 degrees, preferably between 50 and 120 degrees, and more preferred between 80 and 100 degrees, and in that, preferably, in the suspended state, the first flange and the second flange are arranged symmetrically about a plane at right angles to the horizontal.
  • the flanges are releasably connected or adapted to be connected after engagement with a ceiling panel.
  • the flanges may be inserted through longitudinal openings in the top surface of the ceiling panel, one after the other, so that it is avoided to introduce the flanges through the edges of the panel.
  • This may be easier, especially if the grooves in the ceiling panel are rather narrow in order to provide a good grip of the flanges, as in this case, longitudinal displacement of the flanges in the grooves would result in rather large friction.
  • the first groove and the second groove in the ceiling panel may be positioned at a distance from the edge of the ceiling panel. Thereby, the integrity and consequently the strength of the ceiling panel may be further improved, as the edges of the panel are intact.
  • the ceiling panel hanger comprises two substantially V-formed profiles forming a first part that constitutes one of the flanges of the ceiling panel hanger and a second part that constitutes a connecting flange contacting the connecting flange of the other profile, in that the connecting flanges are connected by means of fasteners, such as screws and nuts, in that at least one of the flanges is adapted to be suspended from an overhead structure, for instance in that it is provided with holes for the connection of suspension wires, and in that each profile is preferably formed from a sheet material, such as steel, which is bent at an angle, thereby forming the first part and the second part.
  • the present invention further relates to a suspended ceiling system comprising a ceiling panel and at least one ceiling panel hanger, the ceiling panel having a top surface and a bottom surface and a surrounding edge extending between the top surface and the bottom surface, the at least one ceiling panel hanger comprising two flanges being engaged in a cutout being formed in the top surface of the ceiling panel, the flanges being rigidly connected and adapted for suspension in a ceiling structure.
  • the suspended ceiling system is characterized in that the first flange of the ceiling panel hanger forms an angle with the top surface of the ceiling panel of at least approximately 10 degrees, and the second flange of the ceiling panel hanger forms an angle with the first flange of at least approximately 10 degrees, and in that the cutout in the top surface of the ceiling panel is provided in the form of a first groove in which the first flange of the ceiling panel hanger is engaged and a second groove in which the second flange of the ceiling panel hanger is engaged.
  • first and second groove may be machined by simple cutting, for instance by means of a circular saw, whereby only material corresponding to the thickness of the saw blade need to be removed.
  • a hanger having flanges fitting the first groove and the second groove, respectively, may lock mechanically when inserted into the grooves. As very little material need to be removed from the ceiling panel, a much stronger panel may be obtained. Also a better integrity between the hanger and the panel may be obtained, as the flanges of the hanger may fit closely into the grooves obtained by cutting.
  • the first groove and the second groove are positioned at a distance from the edge of the ceiling panel, and the flanges of the ceiling panel hanger are releasably connected or adapted to be connected after engagement with a ceiling panel.
  • the flanges may be inserted through longitudinal openings in the top surface of the ceiling panel, one after the other, so that it is avoided to introduce the flanges through the edges of the panel, and the above-mentioned advantages may be obtained.
  • the present invention further relates to a method of mounting a ceiling panel in a ceiling structure, whereby at least one ceiling panel hanger is engaged in a cutout in a top surface of the ceiling panel, and whereby the at least one ceiling panel hanger is suspended in the ceiling structure.
  • the method is characterized by that a first flange of the ceiling panel hanger is inserted into a first groove through a first longitudinal opening in the top surface of the ceiling panel, and by that a second flange of the ceiling panel hanger is inserted into a second groove through a second longitudinal opening in the top surface of the ceiling panel, and in that, after insertion of the second flange, the first flange and the second flange are connected.
  • the hanger may lock mechanically when inserted into the grooves.
  • the first flange of the ceiling panel hanger when the first flange of the ceiling panel hanger is inserted into the first groove through a first longitudinal opening in the top surface of the ceiling panel, the first flange is displaced in a direction inclined to the top surface of the ceiling panel and thereby enabling insertion of the second flange of the ceiling panel hanger into the second groove through the second longitudinal opening in the top surface of the ceiling panel, and, after insertion of the second flange, the first flange of the ceiling panel hanger is retracted partly out of the first groove, thereby enabling connection of the first flange and the second flange.
  • a compact hanger may be utilized and at the same time it may be obtained that the flanges of the hanger point away from each other in the direction from the top surface and into the panel.
  • This latter configuration may be advantageous in that the bottoms of the grooves are spaced longer from each other, thereby improving the integrity of the panel structure.
  • the present invention further relates to a method of manufacturing a ceiling panel for suspension in a ceiling structure by means of a ceiling panel hanger, whereby at least one cutout adapted for engagement with the hanger is formed in the top surface of the ceiling panel.
  • the method is characterized by that a first cut is performed in the top surface of the ceiling panel by means of a circular saw, whereby a blade of the circular saw is inclined to the top surface of the ceiling panel as the blade is advanced in its radial direction along the top surface, and by that a second cut is performed in the top surface of the ceiling panel by means of the circular saw, whereby the blade of the circular saw is inclined relative to its orientation during the first cut as the blade is advanced in its radial direction along the top surface.
  • a much simpler and easy method of manufacturing is obtained than it is the case, for instance, by prior art channels of inverted-T configuration.
  • Fig. 3 shows a perspective view of a suspended ceiling system 1 according to the invention.
  • the suspended ceiling system 1 comprises a ceiling panel 2 that is suspended by means of two ceiling panel hangers 3.
  • the ceiling panel hangers 3 are suspended from a not shown overhead structure by means of wires 4.
  • the suspended ceiling system 1 is preferably of the so-called island type, wherein separate ceiling panels are suspended at a distance from each other, thereby forming so-called islands hanging from an overhead ceiling structure.
  • the islands may among other things improve the acoustic properties of a room and may have decorative properties.
  • the ceiling panel 2 in Fig. 3 comprises a top surface 5 and a bottom surface 6 and a surrounding edge 7 extending between the top surface 5 and the bottom surface 6.
  • the ceiling panel 2 shown is rectangular, but it may have any suitable form, among others square, triangular, oval, round or forms composed by such forms.
  • the ceiling panel 2 may have varying thickness.
  • the ceiling panel 2 is preferably made of mineral wool, such as stone wool, and preferably of a density in the interval of 60-150 kg/m 3 , and preferably a thickness of at least 20 mm.
  • the area weight may be, for instance, between about 2-5 kg/m 2 , but any suitable material could be used according to the invention.
  • the material is preferably substantially compact and substantially dimensionally stable.
  • Fig. 1 shows a cross-section through a part of the ceiling panel 2 in Fig. 3 adapted for engagement with a ceiling panel hanger 3.
  • Two cutouts in the form of a first groove 8 and a second groove 9 are formed in the ceiling panel 2 so that they extend from the top surface 5 and are adapted for engagement with flanges 10, 11 of a ceiling panel hanger 3 as shown in Fig. 2 .
  • the first groove 8 forms an angle a with the top surface of 45 degrees
  • the second groove 9 forms an angle b with the first groove 8 of 90 degrees.
  • the first groove 8 and the second groove 9 are arranged symmetrically about a plane at right angles to the top surface 5.
  • first groove 8 may form any suitable angle with the top surface of at least approximately 10 degrees
  • second groove 9 may form any suitable angle with the first groove 8 of at least approximately 10 degrees.
  • the preferred angles a, b may depend on the flexibility and the dimensional stability of the material of the ceiling panel 2. For instance, if the dimensional stability of the material is very good, the angle a and/or the angle b may be rather small.
  • the first and second grooves 8, 9 are positioned at a distance from the edge 7 of the ceiling panel 2, so that they do not penetrate the edge. In this way, the integrity and stability of the ceiling panel is improved, and the grooves are not visible from below the panel which may be preferred for esthetical reasons.
  • the ceiling panel hanger 3 comprises two substantially V-formed profiles 18, 19 forming a first part that constitutes one of the flanges 10, 11 of the ceiling panel hanger and a second part that constitutes a connecting flange 13.
  • the two connecting flanges 13 of either profile, respectively, contact each other and are releasably connected by means of screws 14 and nuts 15. Any suitable number of screws 14 are inserted through holes 16 in the connecting flanges 13, see Figs. 4 and 5 .
  • Other suitable fasteners or locking means for instance clips or even glue or soldering may be used.
  • the ceiling panel hanger 3 is suspended by means of the suspension wires 4 inserted through holes 17.
  • Each V-formed profile 18, 19 is preferably formed from a relatively thin sheet material, such as steel, which is bent at an angle, thereby forming the first part and the second part. However, it may also be injection moulded or extruded in plastic material.
  • the ceiling panel hanger 3 forms an inverted Y, whereby the flanges 10, 11 fits into the grooves 8, 9, respectively, of the ceiling panel shown in Fig. 1 as described above.
  • Figs. 6a to 6d illustrate the process of mounting the ceiling panel hanger 3 in the ceiling panel 2, in the embodiment shown in Figs. 1 and 2 .
  • the first flange 10 of the first V-formed profile 18 is inserted fully into the first groove 8 of the ceiling panel 2, see Fig. 6a .
  • space above the top surface 5 is provided for insertion of the second flange 11 of the second V-formed profile 19 into the second groove 9 of the ceiling panel, see Fig. 6b .
  • the second flange 11 is, however, only inserted approximately halfway into the second groove 9, see Fig. 6c .
  • the second groove 9 does not need to be as deep as the first groove 8, however, assembly and even manufacture may be facilitated when the grooves 8, 9 are of equal depth.
  • the first groove 8 and the second groove 9 are positioned so that they form parallel, longitudinal openings 20, 21 in the top surface 5 and that the distance between the grooves increases in the direction away from the top surface of the ceiling panel.
  • the flanges 10, 11 are not inserted fully into the grooves 8, 9 in the final position, as it may be seen in Fig. 6d .
  • the grooves are not deeper than necessary, as this could influence the integrity of the ceiling panel.
  • the distance X between the first longitudinal opening 20 of the first groove 8 and the second longitudinal opening 21 of the second groove 9 corresponds substantially to the extent Y of the first groove or of the second groove in a direction parallel to the top surface 5 and at right angles to the longitudinal opening of the groove, see Fig. 2 .
  • the grooves may be a little deeper, so that, for instance, X is approximately 90 per cent of Y.
  • the distance X may be equal zero or close to zero.
  • the flanges 10, 11 have the form of combs, whereby the teeth of the combs may cross each other.
  • the connection flanges 13 of the V-formed profiles 18, 19 contact each other oppositely relative to the embodiment shown in Figs. 1 to 3 .
  • the connection flange 13 of the left-hand V-formed profile 18 would be placed to the right of the connection flange 13 of the righthand V-formed profile 19.
  • the comb-formed flanges 10, 11 could then reach until the bottom of the grooves 8, 9, as no retraction of a flange would be necessary at the mounting procedure.
  • the ceiling panel 2 may be manufactured by forming the grooves 8, 9 in the form of cutouts by forming a first cut in the top surface of the ceiling panel by means of a circular saw, whereby a blade of the circular saw is inclined to the top surface of the ceiling panel as the blade is advanced in its radial direction along the top surface. A second cut is then performed in the top surface of the ceiling panel by means of the circular saw, whereby the blade of the circular saw is inclined relative to its orientation during the first cut as the blade is advanced in its radial direction along the top surface.
  • the thickness of the grooves corresponds approximately to the thickness of the blade of the circular saw.
  • the grooves may also be produced in other suitable ways, for instance by milling.
  • the thickness of the grooves may be slightly smaller than the thickness of the flanges 10, 11 to be introduced into the grooves, thereby ensuring a good grip.
  • the grooves may also be thicker than the flanges, as the flanges will still be mechanically locked in the grooves.
  • the depth of the grooves may be a compromise between on the one hand a good grip between the flange and the groove and on the other hand a good integrity of the panel. In other words, if the grooves are too deep, the integrity may be compromised. However, this could be counteracted by gluing the flanges into the grooves.
  • a good compromise could be that the grooves extend until a depth D of 50 to 85, preferably 60 to 75, and more preferred about approximately 70 per cent of the thickness T of the panel, see Fig. 1 , whereby D is measured at right angles to the top surface 5 of the panel 2.
  • an advantageous relation between the length of the flanges 10, 11 and the length of the ceiling panel 2 could be between 50 and 90, and preferably between 60 and 70. It is noted that the maximum length of the grooves 8, 9 may have to be longer than the flanges 10, 11 if the grooves are manufactured by means of a circular saw.
  • Fig. 7 shows another embodiment of the suspended ceiling system 1 according to the invention.
  • the distance between the grooves 8, 9 decreases in the direction away from the top surface 5 of the ceiling panel 2.
  • the flanges 10, 11 may be fully inserted into the grooves 8, 9, respectively, as no retraction of the first flange 10 is necessary after insertion of the second flange 11.
  • the ceiling panel hanger does not cover much of the surface of the ceiling panel, as this could reduce the insulating effect of the ceiling panel. Therefore, the parts of the ceiling panel hanger extending above the ceiling panel form an angle with the top surface of the ceiling panel.
  • Fig. 8 shows yet another embodiment of the suspended ceiling system 1 according to the invention.
  • one ceiling panel hanger 3 is provided at either corner of the ceiling panel 2. Only one corner of the ceiling panel is shown in the figure.
  • the ceiling panel hanger 3 is composed by a first part 22 and a second part 23 that in the mounted position shown are connected by means of flanges 24 that are suspended by means of wire.
  • a first flange 25 of the first part 22 is partly inserted into a first groove 27 of the ceiling panel 2
  • a second flange 26 of the second part 23 is partly inserted into a second groove 28 of the ceiling panel 2.
  • the first groove 27 and the second groove 28 form longitudinal openings 29, 30, respectively, that are at right angles to each other. Any other suitable angle is also possible.
  • the first groove 27 and the second groove 28 each form an angle of 45 degrees with the top surface 5 of the ceiling panel.
  • the first groove 27 may form an angle of 45 degrees with the top surface 5
  • the second groove 28 may form an angle of 90 degrees with the top surface 5.
  • the process of mounting the ceiling panel hanger 3 in the ceiling panel 2 in this embodiment is similar to the process illustrated in Figs. 6a to 6d .
  • Fig. 9 shows yet another embodiment of the suspended ceiling system 1 according to the invention.
  • one ceiling panel hanger 3 is provided at either corner of the ceiling panel 2.
  • the ceiling panel hangers have a cross-section similar to that of the embodiment shown in Fig. 7 , but the length of the hangers is substantially shorter, as it may be seen in Fig. 9 .
