Description

Title: Suspended ceiling

The present invention generally relates to suspended ceilings.

Suspended ceilings are generally known for providing a lowered ceiling relatively easily, in particular in offices, hospitals, schools, and the like. Pipes can be concealed in the space between the lowered ceiling and the actual ceiling of the room in question, for example for ventilation, electricity cables, etc.

Figure 1 shows a schematic cross-section of a known system ceiling 1. The figure shows a ceiling 2 of a room, for example an office space. Carrier rails 10 are suspended from the ceiling 2, for example by means of a suspension wire 11. The carrier rails 10 have an inverted T-shaped cross-section, with a vertical body 12 and horizontal legs 13. The carrier rails 10 are mounted in a rectangular pattern, typically with dimensions of about 60 cm x 120 cm, and the total width of the two horizontal legs 13 of the carrier rails 10 is typically about 2.5 cm. The thickness (height) of the legs 13 is typically about 3 mm. The thickness (width) of the body 12 is also typically about 3 mm. The system furthermore comprises rectangular ceiling plates 20, typically of plasterboard, which are laid down on the horizontal legs 13 of the carrier rails 10. For the room in question, the combination of the ceiling plates 20 and the carrier rails 25 forms a lowered ceiling 3.

A drawback of the known suspended ceilings is that they are not attractive from aesthetic point of view. The bottom surface 21 of the ceiling plates 20 visible from the space in question is typically finished in an even color, usually white or almost white, and the metal carrier rails 10 are typically also finished in an even color. When the intention is to obtain a uniform ceiling, and the ceiling plates 20 and the carrier rails 10 are finished in the same color for this purpose, it often appears over time that the ceiling plates 20 and the carrier rails 10 are mutually supported. discolored in different ways, causing a color difference. For this reason it is also not unusual for people to choose to give the ceiling plates 20 and the carrier rails 10 mutually different colors, for example light gray and white. In both cases, however, a pattern of rectangular surfaces with differently colored stripes between them is created on the lowered ceiling 3.

Up to now, there are only limited possibilities to increase the aesthetic value of such a lowered ceiling 3. It is of course possible to paint the entire ceiling after installation, but this is labor intensive, certainly if one does not want a uniform color but a beautiful pattern or a beautiful representation. Furthermore, it is difficult to replace a damaged ceiling plate invisibly.

The present invention has for its object to provide a solution to the aforementioned problems.

In particular, the present invention has for its object to provide a system ceiling on which in principle any arbitrary representation can be applied, room-wide, without visible seams, whereby individual plates can again be replaced relatively easily. Such a ceiling will in particular contribute to the well-being of persons forced by circumstances to look at the ceiling for a longer period of time, such as, for example, patients in a dental chair, bedridden persons, etc.

These and other aspects, features and advantages of the present invention will be further elucidated by the following description with reference to the drawings, in which like reference numerals indicate like or similar parts, and in which: figure 1 shows a schematic cross-section of a known system ceiling; Figure 2 illustrates a detail of a system ceiling according to the present invention; Figures 3A-3B illustrate a first embodiment of the present invention; Figures 4A-4B illustrate a second embodiment of the present invention; Figures 5A-5B illustrate a third embodiment of the present invention; Figure 6 illustrates a knife 5 represented by the present invention; Figure 7 is a block diagram illustrating the calculation of the printing on the ceiling plates.

Figure 2A is a schematic cross-section of a ceiling plate 120 according to the present invention, with a bottom surface 121 and a top surface 122, and a peripheral edge 123. The ceiling plate 120 can be designed as a plasterboard, but other materials are also conceivable. However, it is important that the ceiling plate also meets 15 requirements with regard to fire resistance and anti-allergy properties, and then plaster is a good choice. The ceiling plate 120 can have standardized dimensions, for example 60 cm x 120 cm, but other dimensions are also possible.

Along the peripheral edge 123, the bottom surface 121 of the ceiling plate 120 is provided with a step-shaped recess 124, which recess 124 has an upper surface 125 and a side surface 126. The depth of the depression 124, i.e. the height of the side surface 126, is equal to the thickness of the legs 13 of carrier rails 10, for example 3 mm, which are associated with the ceiling plate 120. The width of the depression 124, i.e. the width of the upper surface 125, corresponds to the width of a leg 13, typically about 10 mm.

Figure 2B is a schematic cross-section of a carrier rail 10 with two mounted ceiling plates 120.

It can clearly be seen that the lower surface 121 of the ceiling plate 120 is flush with the lower surface 14 of the carrier rail 10. The lowered ceiling 3 proposed by the present invention is therefore a tight whole, in contrast to known ceilings where the carrier rails are visible as 35 "strips" lying on the ceiling.

According to a second aspect of the present invention, each ceiling plate 120 and each carrier rail 10 on the relevant bottom surface 121 and 14 respectively are provided with a 4 foil-shaped image carrier. The material of the image carrier may be a paper or the like, but due to the fire resistance and anti-allergy requirements, the material is preferably a resin-coated canvas; such a material is known per se for covering walls and ceilings, and therefore does not need to be further described. The image carrier is applied to the ceiling plate 120 by means of preferably a flame-extinguishing glue kit; since such an adhesive kit is known per se, a further description thereof is not necessary here. The image carrier can be applied to the carrier rail 10 by means of a double-sided adhesive tape, which product is also known per se.

Figures 3A-3B illustrate a first embodiment of the present invention. In Figure 3A, carrier rails 10 are shown with an inverted T-shaped cross section. The number of carrier rails 10 arranged side by side in this manner will depend on the size 20 of the relevant chamber, as will be clear to a person skilled in the art; two such carrier rails 10 are shown in the figure. Furthermore, a carrier rail 10 'is shown, which is attached to a wall 4 by means of a spacer block 5. The mutual distance between the mutually parallel rails 10 can always be the same, but this is not essential. The figure further shows two ceiling plates 120, distinguished from each other by the addition of a letter A and B, which are placed on the carrier rails 10, 10 '.

In Figure 3B, the ceiling plates 120 are mounted in place on the carrier rails 10, 10 ', the legs 13 of the carrier rails 10, 10' engaging in the step-shaped recess 124 of the ceiling plates 120, so that the bottom surface 121 of each ceiling plate 120 is flush with the lower surfaces 14 of the carrier rails 10.

As a next step, a foil-shaped image carrier 130 is applied to the bottom surface 121 of each ceiling plate 120. The film-shaped image carrier 130 covers the entire lower surface 121 of the ceiling plate 120, as well as the lower surface 14 of at least one carrier rail 10, 10 '. It is clearly shown in Figure 3C that the image carrier 130A mounted against the lower surface 121 of the ceiling plate 120A resting on the carrier rail 10 'with an L-shaped cross-section attached to the wall 4, as well as the lower surface 14 of 5 attached to the wall-mounted carrier rail 10 'as well as the bottom surface 14 of the next carrier rail 10 covers. The image carrier 130B which is arranged on the bottom surface 121 of the second ceiling plate 120B only covers the bottom surface 14 of the second carrier rail 10. For each subsequent ceiling plate it will always hold that the image carrier placed thereon also covers the bottom surface of the subsequent carrier rail.

As a next step, the image carrier 130 is cut along the separation between the ceiling plate 120 and the corresponding carrier rail 10 and 10 '. In Figure 3C an arrow S1 indicates the cut made between the first ceiling plate 120A and the carrier rail 10 'mounted against the wall, an arrow S2 indicates the cut made between the first ceiling plate 120A and the first carrier rail 10 and a third arrow S3 denotes a cut made between the second ceiling plate 120B and the second carrier rail 10.

Figure 3D shows the final situation after the image carriers have been cut. The entire lower surface of the lowered ceiling, i.e. the lower surfaces 25 of the ceiling plates 120 as well as the lower surfaces of the carrier rails 10, 10 ', is covered by image carriers 130, while the individual ceiling plates 120 lie loosely on the carrier rails 10, 10' and can easily be removed again.

Figures 4A to 4C show a second embodiment of the present invention. In this embodiment, image carriers 140 are provided in advance on the bottom surface 121 of the ceiling plates 120. Then, those ceiling plates 120 are mounted on the carrier rails 10, 10 ', as shown in Figure 4A.

In this embodiment, the present invention provides separate image carrier strips 145, which are applied to the bottom surface 14 of the carrier rails 10, 10 ', as shown in Figure 4B. The end result achieved, 6 illustrated in Fig. 4C, is identical to the situation of Fig. 3D, with the proviso that it was not necessary to cut through the film-shaped image carriers.

In the embodiment shown, the image carrier strips 145 are applied to the carrier rails 10, 10 'after the ceiling plates 120 have been placed. However, this order may also be reversed.

Figures 5A to 5D show a third embodiment of the present invention. In a similar manner as in the second embodiment, each ceiling plate 120A, 120B is provided in advance with a foil-shaped image carrier 150A and 150B, respectively, provided on the respective lower surface 121. In this case, in deviation from the second embodiment, the size of the image support 150 is larger than the size of the bottom surface 121 of the relevant ceiling plate 120. In Figure 5A it is shown that the first image support 150A arranged on the bottom surface of the first ceiling plate 120A, a first strip 151 protruding outside that below-surface 121, the width of which corresponds to the width of the bottom surface 14 of the carrier rail 10 'mounted against the wall 4, and opposite a second protruding strip 152 of which the width corresponds to the width of the bottom surface 14 of the first free-hanging support rail 10. The image support 150B against the bottom surface 121 of the second ceiling plate 120B is only provided with a second protruding strip 152, the width of which corresponds to the width of the bottom surface 14 of the second free-hanging carrier rail 10.

Figure 5B shows that the ceiling plates 120A and 120B with the image carriers 150A and 150B attached thereto are placed on the carrier rails 10, 10 ', the projecting image carrier strips 151, 152 remaining free from the carrier rails 10, 10'. When placing the ceiling plates 120, care is taken that the projecting image carrier strips 151, 152 are maneuvered under the carrier rails 10, 10 '.

In a next step, the projecting image carrier strips 151, 152 are secured against the lower surface 14 of the adjacent carrier rails 10, 10 ', as indicated by the arrows P1, P2 and P3 in Figure 5B. The situation then achieved, illustrated in Figure 5C, is identical to the situation shown in Figure 3C. After applying the cuts as indicated by the arrows S1, S2 and S3 in Figure 5C, the lowered ceiling is ready, as illustrated in Figure 5D.

It is noted that it is possible for the projecting image carrier strips 151, 152 to be provided with a protective film which in the situation of Fig. 5B is removed in order to release the adhesive layer on those strips 151, 152. For the sake of simplicity, such a protective film is not shown in the figures.

For making the cuts S1, S2 and S3, as discussed above, use can in principle be made of an ordinary knife. To prevent damage, the present invention proposes to use a knife with a rotating knife wheel. Figure 6 shows a preferred embodiment of a knife 60 to be used for this purpose. The knife 60 has a handle 61, a handle 62, a holder 63 attached to the handle 62, and two knife wheels 64 and 65 rotatably mounted on either side of the holder 63. The mutual distance between the two knife wheels 64 and 65 is equal to the width of the carrier rails 10, 10 '. During use, such a knife is guided by the carrier rails 10, so that the chance of it spreading is very small.

In principle, people are free to choose the images that are applied to the image carriers. In a preferred embodiment, as illustrated in Figure 7, one starts from a photo 71, which is digitally entered into a computer 70. Via, for example, a keyboard 72, the dimensions of the space concerned, the dimensions of the space concerned, are given in the computer 70. carrier rails, the dimensions of the plates 120, etc. in. The computer performs a calculation in which the photo is enlarged to the size of the ceiling, and in which the magnified photo is projected onto the ceiling.

The computer then calculates for each ceiling component, that is to say for each individual ceiling plate and for each individual carrier rail, which cut-out of the original photo corresponds to that particular ceiling component; information defining those cutouts is stored in a memory 73 associated with the computer, for example, a hard disk, a DVD, or the like. On the basis of the information in the memory 73, the computer 70 drives a printer 80, which prints on the film strips and provides a serial number or the like. The foil strips can be printed before they are applied to ceiling plates, but it is also possible that the foil is printed after it has been applied to a ceiling plate.

Since printers which can print foil strips, and even foil-coated ceiling plates in this way, are known per se, a further description of such printers is not necessary.

An operator may install the printed foil strips or ceiling plates provided with printed foil strips in the final ceiling on the basis of the said sequence numbers.

It is noted that it is possible, if desired, to repair a damaged ceiling plate or bearing rail by having the associated photo-cutout reprinted on a new foil strip, based on the relevant serial number and the information in the memory 73.

It will be clear to a person skilled in the art that the invention is not limited to the exemplary embodiments discussed above, but that various variants and modifications are possible within the scope of the invention as defined in the appended claims.

Features that have only been described for a particular embodiment are also applicable to other described embodiments.
