Abstract
Description
- The invention relates to a suspension frame for a false ceiling comprising main profiles that in cross-section have substantially the form of an inverted T, or a twofold T, in other words, a profile with a body and, in working position, at least at the bottom side two laterally veering flanges and cross-profiles with an analogous cross-section cooperating therewith.
- False ceilings that use main profiles that intersect cross-profiles at an angle of 90° are known. The voids between said profiles are finished off with square, often rectangular panels. The originated pattern is thus always orthogonal. The realisation of ceilings differing from one of said orthogonal patterns is then, for technical and economical reasons, not or very difficultly feasible.
- A structure for a false ceiling that exclusively allows the realisation of an orthogonal structure is known from the U.S. patent 3,292,336. On the other hand, a profile enabling to realise checkered grids is known from the document AT 316081, but the pattern can never deviate from the originally established shape.
- The object of the invention is now to realise a suspension frame for such ceilings that enables to install cross-profiles at any angle in regard to the main profiles, so as to be able to use rectangular, gridded or trapezoidal shaped panels or combination thereof in the finishing of the ceiling too.
- To render this possible according to the invention, the body of said cross-profile is extended at each extremity further than the flanges pertaining thereto and bent over an angle, while the main profile, in the area where one or more cross-profiles intersect the main profile at said angle, comprises grooves to lodge the extremities of cross-profiles.
- In the most preferred embodiment, the angles at which the extremities of the body of the cross-profile are bent comprise 45°, respectively 135°.
- A particularity of the invention is that the flanges pertaining to a cross-profile, which are placed underneath in working position, are smaller that the flanges pertaining to a main profile, in such a manner that the intersection between two cross-profiles that reach out towards each other at an angle of 45°, resp. 135° joins precisely the lateral edge of the flange of a main profile.
- Characteristic of the invention is that the relation between the width A of a main profile and the width B of all cross-profiles comply to the equation B=1/2A√2.
- Other details and advantages of the invention will appear from the following description of a suspension frame for a false ceiling according to the invention. This description is exclusively given by way of example and does not limit the invention. The reference numbers relate to the annexed figures.
- Figure 1 is a lateral view of the portion of the main profile in the area where the grooves appear, intended to lodge the extremities of the converging cross-profiles.
- Figure 2 is partly a top view and partly a cross-sectioning through a main profile and several converging cross-profiles.
- Figure 3 shows a perspective view of the extremities of several converging cross-profiles and a portion of a main profile.
- Figure 4 to 9 illustrate schematically several possible patterns to be realised by means of main- and cross-profiles according to the invention.
- The suspension frame shown by these figures comprises the combination of
main profiles 1, which comprise as usual abody 2 and two laterally extendingwings 3. The main profiles, as incidently the cross-profiles that will be described too, therefor show the form of an inverted T. It is clear that a so-called twofold T could also be used. - In the
body 2 of themain profiles 1, where one or more cross-profiles are to be fastened to the main profile, a series ofgrooves 4 are provided in order to lodge the extremities of cross-profiles (minimum one, maximum six). - The cross-profiles can be
profiles 5, which are mounted orthogonally with respect to themain profile 1, or left and right cross-profiles that are to be mounted for example at an angle of 45° with respect to amain profile 1. Such left and right cross-profiles are indexed 6 and 7 in the figures 2 and 3. - The body of all these cross-profiles are prolonged by an extremity which extends into the core-axis of the
body 2 of aprofile 5. The extremity of across-profile 5 is indexed 5'. The extremities of the left andright cross-profiles - The extremities 6' and 7' of the
body 2 of a right andleft cross-profile 6, resp. 7, are bent at an angle of 45° with respect to the body of such right and left profiles, but this angle could also comprise 135°. - All extremities of the different cross-profiles , i.e. the extremities 5', 6' and 7', display a
slot 8 above, and anotch 9 at the bottom. - From the figures 1 and 2 it can be derived that the extremities 5', 6', 7' of the different cross-profiles, in the grooves or
notches 4 of amain profile 1 alternatively left and right, fit next to each other in thegrooves 4. In figure 2 one can see how the extremities of the different cross-profiles fit next to each other in thegrooves 4 of amain profile 1, and how they can no longer dislodge from these grooves, owing to the presence of thebrackets 8 and thenotches 9. - In order to present a smooth junction of the
different cross-profiles wings 3 of amain profile 1, these cross-profiles are cut out according to the desired angle. Across-profile 5 that converges with twocross-profiles - It will be noticed that the core-axis of all cross-profiles converging to a main profile join in one point on that main profile. Consequently, two or pairs of cross-profiles can always be found on both sides of a main profile, the core-axis of which are in each other's prolongation. This provides an installation as well as an economical advantage with respect to the panels that fill the openings between the different profiles.
- Standard panels are square of rectangular. These standard panels can now easily be made to fill the openings in the diagonal system. When cut diagonally, the leftover material can directly be reusable in another place in a pattern, owing to its shape and dimensions, leftover material is thus in no way lost.
- The relation between the width of a cross-profile and that of a
main profile 1 can be determined as follows. The mathematical ratio between both widths, essential to the suspension system according to the invention, resides in the relation between the width A of themain profile 1 and the width B of all cross-profiles, i.e.: B = 1/2A√2. This results for example, for a width of the wings of a main profile equal to 21, in a width of the wings of a cross-profile equal to the half of 21 x 1,4142... This determines the width B of all cross-profiles, equal to 14,8491 rounded off to 15. - It is evident that with the help of the different profiles and the combinations between main- and cross-profiles, a plurality of variants can be assembled, and therefor, that a false ceiling can adapt certain patterns that deviate greatly from the upto now rather monotonous orthogonal patterns.
- Consequently, the invention is not limited to the embodiments described hereinabove, and many variants could be applied for as far as these modifications stay within the limits of the claims annexed hereto.
