Description

INTERIOR CEILING ELEMENT AND METHOD FOR
MANUFACTURING IT
The present invention relates to an interior ceiling element, in particular an interior ceiling element that it is intended should be capable of being mounted in a trusswork with fixed module dimensions, and that is suspended from the roof. The invention concerns also a method for the manufacture of such an interior ceiling element.
It is common that interior ceilings are built up with the aid of such interior ceiling elements, and many such elements with different properties, such as appearance, colour, sound-reflecting properties, sound absorption, etc., are available.
It is, however, the case that in many cases the wish to obtain an attractive appearance conflicts with the requirements of sound absorption. It is therefore one purpose of the present invention to achieve a new interior ceiling element that makes it possible to present an aesthetically pleasing appearance and where this at the same time makes possible improved sound absorption.
It is a purpose of the invention also to achieve a method that makes possible a simple manufacturing procedure for such an interior ceiling element.
The purpose to achieve an interior ceiling element is reached, according to the invention, through one or several parts being excised and pressed out from the element such that they protrude downwards from the essentially plane surface of the element when the element is mounted in an interior ceiling.
It is preferable that the interior ceiling element be an element of fibre material, and that one side of the element of fibre material be covered by felt, which constitutes the surface of the element that faces downwards. According to one preferred embodiment of the interior ceiling element according to the invention, the element of fibre material is a polyester fibre element, and the felt is an acoustic felt.
According to a further preferred embodiment of the interior ceiling element according to the invention, at least one of the, one or several, excised parts is completely pressed out from the element, possibly turned over, and reinserted into the element in the opposing direction and protruding downwards from the essentially plane surface of the element.
According to a further preferred embodiment of the interior ceiling element according to the invention, each of the excised parts, of which there are at least one and possibly several, comprises a first part and a further part that is surrounded by the first part and where not only the first part but also the second part are at least partially pressed out from the element, whereby the further part is pressed out a greater distance than the first part.
The purpose of achieving a method for the manufacture of an inner ceiling element is reached, according to the invention, through at least one or several parts being excised from an element and pressed out such that they protrude at least a certain distance from the principally plane surface of the element.
According to one preferred embodiment of the method, one side of the interior ceiling element, which it is appropriate should be an element of fibre material with felt, which constitutes the surface of the element that faces downwards, whereby this covering operation takes place before the parts, at least one or several, are excised from the element.
According to one preferred embodiment of the method according to the invention, the, at least one or several, excised parts are pressed completely out of the element, possibly turned over, and partially reinserted into the element. According to a further preferred embodiment of the method according to the invention, at least one first part is excised from the element and one further part, which is surrounded by the first part, is excised from the first part, and not only the first part but also the second part are pressed out, whereby the further part is pressed out a greater distance than the first part.
The invention will now be described in more detail in the form of a non-limiting embodiment, illustrated in the attached drawings, where Figure 1 shows a schematic view in perspective of the lower surface of an interior ceiling with interior ceiling elements according to the invention mounted into a trusswork, Figure 2 is a view of an interior ceiling element according to the invention in a second embodiment, and Figure 3 shows a feature of the interior ceiling element shown in Figure 2 with a first excised part and one additional excised part completely removed from the interior ceiling element. Thus, Figure 1 shows an interior ceiling comprising a trusswork 1, with normal, essentially completely flat, interior ceiling elements 2 shown in the right part of the drawing. In the left part of the drawing there are shown a number of interior ceiling elements 3 according to the present invention, in which interior ceiling elements several parts 4 have been excised and somewhat pressed out from the element itself 3 such that they protrude downwards from the essentially plane surface of the element 3 with the element mounted in the trusswork 1.
In the example shown in Figure 1, the interior ceiling elements 3 according to the invention are covered with felt on the lower surfaces, which is the surface that is visible in the drawing, and four excised and pressed-out parts 4 are arranged in each element 3. As is shown in Figure 1, all excised and pressed-out parts 4 have the same shape, but they demonstrate in the example shown different colours of the excised and pressed-out parts 4. The excised and pressed-out parts 4 are in this case not from the same interior ceiling element 3 in which they are mounted: they have been excised and pressed out from other interior ceiling elements, or are, at least, of the same material, and they have been inserted into the interior ceiling elements 3 shown. As is made clear in the drawing, it is possible in this way with the differently coloured excised and pressed-out parts 4 to vary the pattern of the interior ceiling that is constructed, in order to achieve a more aesthetically varied and attractive appearance.
In addition to the aesthetically varied and attractive appearance of the excised and pressed-out parts 4, the excised and pressed-out parts also have a purely technical function in that the varying surface of the interior ceiling elements 3 contributes to absorbing sound, and in this way acts to dampen sound.
It is appropriate that the material of the interior ceiling elements 3 themselves, according to the invention, and also of the excised and pressed-out parts 4, be an A-classified polyester fibre element that is preferably covered with acoustic felt on its surface that faces downwards. It is obvious that the interior ceiling elements, as also the excised and pressed out parts 4, may be of other similar materials with sound-absorbent properties.
An example of a second embodiment of an interior ceiling element 3 according to the invention is shown in Figure 2, where each one of the excised parts 4 is formed by a first part 5 and an additional part 6 that is surrounded by the first part 5, and where not only the first part 5 but also the second part 6 have been at least partially pressed out from the element 3, whereby the additional part 6 has been pressed out a greater distance than the first part 5.
As the interior ceiling element 3 is shown in Figure 2, it is furthermore so manufactured that the side of the interior ceiling element that is normally visible, i.e. the side that in the mounted condition is facing downwards, has a surface covering of one colour, and the side that faces in the opposite direction has another colour. If the two excised parts, i.e. the first part 5 and the additional part 6, are subsequently completely removed from the element 3, and the first part 5 is turned over before it is reinserted into the element 3 while the additional part 6 is inserted in the same direction as it originally had, the special optical effect can in this case be achieved that the additional part 6 is seen as being surrounded by a part, the first part 5, with another colour, while this first part is also in this case seen to have another colour than the interior ceiling element 3 itself.
Figure 3 shows a detailed view of a part of the interior ceiling element 3 shown in Figure 2, but one in which the two excised parts 5, 6 in the upper cavity have been removed from the interior ceiling element 3 and are individually displayed at the side of the interior ceiling element.
It is obvious that it is possible in a corresponding manner to combine further colours in further parts, and also that the shapes of the excised parts 4, 5, 6 may be other than what is shown in the various embodiments. It is, of course, also possible to have different shapes for different excised parts in one and the same interior ceiling element, just as it is also possible to have more than two excised parts that surround each other at one and the same cavity, in order to further increase the range of variation for the interior ceiling element according to the invention.
A method for the manufacture of an interior ceiling element is achieved, according to the invention, quite simply through an interior ceiling element, preferably an element of fibre material, being covered on at least one side by felt, and through at least one or several parts being excised from the element and pressed out such that they protrude at least a certain distance from the essentially plane surface of the element.
As has been mentioned above, at least one first part can, according to the invention, be excised from the element and one further part, which is surrounded by the first part, be excised from the first part, and not only the first part but also the second part can be pressed out, whereby the further part is pressed out a greater distance than the first part.
It is also possible that the, at least one or several, excised parts are pressed out of the element completely, possibly turned over, and partially reinserted into the element. The excision of the excised parts can be carried out by, for example, a programmable computer cutting machine that cuts out the desired pattern in the interior ceiling element 3. It is preferable that the computer cutting machine be a CNC machine. It is obvious that it is possible also to carry out the excision in other ways, for example through punching.
With a material in the interior ceiling element as has been mentioned above, it should not be necessary to fasten the excised parts 4, 5, 6 into the interior ceiling element 3, but it is obvious that it is possible also to glue the excised parts into the interior ceiling element such that they do not fall out.
The interior ceiling element according to the invention is primarily intended to be used during the assembly of internal ceilings, but it is obvious that it is possible for it to be used also in outdoor environments, at least in such environments that are protected from rain, and also as sound absorption mounted at a wall.
The elements are normally manufactured with dimensions adapted to fit into standard trussworks for interior ceilings, i.e. normally with dimensions 600 x 600 mm or 600 x 1200 mm. It is, however, obvious that they can be manufactured also with other dimensions, which may be necessary in a particular case.
