Definitions

  • the invention relates to a lamella diaphragm, in particular a screen, and a method for producing lamellae for such a lamella diaphragm.
  • Conventional slat blinds consist of a series of vertically or horizontally running slats and often have an adjustment mechanism with which the slats as a whole or a part thereof can be adjusted from a closed position to an open position.
  • the closed position all of the lamellae of the lamella diaphragm lie essentially in one surface, in particular in a plane, and they overlap in a certain area of their width. If the adjustment mechanism is actuated to open the lamella diaphragm, the individual opened lamellae lie essentially in mutually parallel planes.
  • Such conventional lamellae are often attached as screens or blinds in front of window fronts or in the interior of the room behind windows which have radiators for space heating in their lower area near the floor.
  • the amount and type of the incident, transmitted and reflected light, the heat radiation which is reflected and passes through the lamella diaphragm, and the air flow and and through the lamella diaphragm are influenced by the respective position of each lamella.
  • slat covers In order to improve the air or heat exchange, slat covers have already been proposed, the slats of which are either Have perforations over their entire width or in the area of their longitudinal edges through which the air can pass.
  • a disadvantage of this arrangement is that the perforations also impair the visual glare effect, since they allow a partial view even when the lamella diaphragm is closed.
  • the invention is based on the object of enabling a lamella diaphragm, the variability, in particular optical variability, of which is increased and which, even in the closed position, allows air to circulate without the visor effect being impaired.
  • the lamellae have elevations and / or depressions on their surface which form air ducts which run essentially transversely to the longitudinal direction of the lamellae and which extend to at least one longitudinal edge of the lamellae.
  • the elevations and / or depressions are arranged substantially perpendicular to the longitudinal direction of the slats.
  • the elevations and / or depressions can also run at a certain angle to the transverse direction of the slats.
  • the elevations and / or depressions are preferably formed only in the region of a longitudinal edge of the slats.
  • the above-mentioned elevations and / or depressions also be formed over the entire width of the slats.
  • elevations and / or depressions are formed only in the region of a longitudinal edge of the slats, such slat edges without elevations and / or depressions can overlap with elevations and / or depressions supporting slat edges in the closed position of the slat diaphragm.
  • the width of the overlapping area in the closed position of the lamella diaphragm is essentially the same as the width of the edge area carrying the elevations and / or depressions.
  • the lamella diaphragm can have vertical lamellae which are arranged so as to overlap that the elevations and / or depressions lie in the overlap region.
  • the height or the depth and the width of the elevations and / or depressions must be selected so that the desired air circulation or optical variability is ensured even when the lamella diaphragm is closed.
  • These dimensions can be selected taking into account other, for example aesthetic, aspects in the range from a few millimeters to a few centimeters.
  • each slat can preferably be provided only over part of the length of each slat in blinds with horizontal slats.
  • either all the lamellas can carry the elevations and / or depressions mentioned or only a part of the lamellas, so that lamellas with elevations and / or depressions alternate with those without the elevations and / or depressions.
  • an aesthetic effect can also be taken into account, which supports the optical variability.
  • the lamellae can be in one piece with the area which bears the elevations and / or depressions mentioned.
  • each lamella with the elevations and / or depressions can have a corrugated lane fixed on a lamella base sheet.
  • a corrugated web can also be laminated from two sides by a smooth layer.
  • the slats can be arranged so that they can be rotated about horizontal or vertical parallel axes in such a way that the slats can be adjusted from a closed position in which they all lie essentially in one surface, in particular a plane, to an open position in which the Slats lie essentially in mutually parallel planes.
  • the edge of the slats, in the area of which the elevations and / or depressions lie, are turned into the space facing away from the window front when the slat cover is opened.
  • the slat panel according to the invention can preferably be used as an adjustable screen in front of window fronts.
  • the use of the lamella diaphragm according to the invention is not limited to this.
  • Alternative types of use are, for example, use as a radiator screen, as a sun screen, for example in the manner of an awning, as a light screen in front of lighting devices and as a false ceiling for the functional or optical reduction in the height of a room.
  • the shaping step can comprise a rolling and / or pressing process.
  • a lamella web suitable for the production of the proposed lamella diaphragm can also be produced in that a corrugated or crimped material, in particular metal, fabric, paper or plastic, on a web of a lamella base material, in particular metal, fabric, paper or plastic , applied and the corrugated or crimped web is fixed on at least part of the length of the web of the lamellar base material so that the corrugated or crimped web goes to at least one longitudinal edge of the web of the lamellar base material.
  • the fixing is preferably carried out by gluing.
  • the corrugated or crimped web can also be fixed by welding on the lamella base material by welding or hot pressing.
  • the special shape of the elevations and / or depressions and the choice of a pattern repeat is largely left to the designer and can be selected according to material properties and aesthetic considerations.
  • a lamella diaphragm 1 has a number of vertically running lamellae 2, which have elevations and / or depressions 4 and 4 ′ running in the transverse direction (hereinafter referred to as waves).
  • waves are only provided in the area of one longitudinal edge 3 of each lamella, while the other longitudinal edge 3 'does not carry such waves.
  • Fig. 1 also shows that the slats 2 provided with the shafts are alternately provided with slat tracks 5 without shafts.
  • FIG. 2 shows a section of the lamella diaphragm 1 according to FIG. 1, three lamellae 2 being shown in a top view in the almost closed position of the lamella diaphragm. It can be seen that the air exchange represented by the arrows 6 also takes place when the lamella cover 1 is in the closed position.
  • the area with the shafts 4 only extends as far as the longitudinal edge 3, while the opposite edge 3 'of the slats 2 has no elevations and / or depressions 4 or 4'.
  • the sections provided with waves overlap in the area of the plate edge 3 and the sections not provided with waves overlap in the area of the plate edge 3 '. Since the slats have no openings or perforations, the screen effect is ensured despite the existing air or heat exchange.
  • the desired amount of light passing through can be set by the position of the slats 2.
  • This adjustability of the amount of light passing through is also ensured if the portion carrying the elevations and / or depressions 4 or 4 'in the region of the edge 3 has a lower light transmission than the portion in the region of the edge 3' where no elevations and / or there are recesses.
  • the elevations and / or depressions 4 and 4 ' can also extend over the entire width of the lamella web.
  • the desired heat or air permeability is ensured by the action of the elevations and / or depressions 4 and 4 ', even when the lamella diaphragm is closed.
  • these elevations and / or depressions can also be embossed into the lamella material, e.g. round bulges and / or depressions, which then also form the air channels.
  • Fig. 3 which is a section D from the embodiment of the lamella diaphragm 1 shown in Fig. 1, shows a successive arrangement of four lamellae 2, the corrugated edges 3 of which, despite the closed position of the lamellae 2, enable a desired air or heat exchange, as is the case here is illustrated by the arrows 6.
  • lamella diaphragm which have lamellae running essentially vertically.
  • lamellae screens are provided with an adjustment mechanism which makes it possible to adjust the position of the lamellae in whole or in part from a closed position, in which all lamellae are essentially in one surface, in particular plane, to an open position , in which the slats are each in mutually parallel planes.
  • the present invention is not limited to such screens, but can also be applied to lamellae in which the position of the individual lamellae is fixed.
  • Such applications are e.g. Louver panels for ceiling cladding or room divider arrangements, in each of these cases a desired light and air or heat exchange from the room behind the louvre panel into the room in front of the louvre panel is ensured by the measures proposed according to the invention.
  • This method has a deformation step in which a web of a lamella material, possibly a composite material, is deformed in such a way that this lamellar web has at least part of its length the waves, elevations and / or depressions described, so that it is essentially transverse to the longitudinal direction form running channels of the lamellar path and extend to at least one longitudinal edge of the lamellar path.
  • a further step consists in a cutting process in which the desired lamella web lengths are cut, possibly with a pattern repeat.
  • a deformation process can include a rolling, stamping and / or pressing process.
  • Materials suitable for such deformation are, for example, composite materials which have a fabric layer on one side and have a plastic layer on the other side. Coated paper can also be used, for example Japanese paper.
  • those lamella materials are preferably selected which, on the one hand, have the required permanent deformability, such as metal, and, if it is light-transparent screen protectors, the desired light transparency.
  • the materials should have a certain stiffness, light fastness and sufficient aging resistance. The stiffness of a lamellar track can also be increased by the molded waves.
  • Fig. 4 illustrates a particularly simple manufacturing process for lamellae shaped according to the invention.
  • a web of corrugated or crimped fabric 2 ' e.g. Metal, fabric, paper or plastic is applied to a smooth sheet 2 of a lamella base material and fixed thereon by a suitable means, so that the corrugated or crimped sheet extends at least to the longitudinal edge 3 of the sheet of lamella base material 2.
  • the reference numerals 7 show places at which the corrugated or crimped fabric web 2 'are fixed on the web 2 of the lamellar base material.
  • the lamellae can also have elevations and / or depressions which do not run exactly perpendicular to the longitudinal direction of the lamellae, but rather at a certain angle to the transverse direction of the lamellae.
  • 5 shows in its parts A, B and C three examples of such oblique waveforms. 5A, rectangular elevations and depressions 4 and 4 'run obliquely downward from the right lamella edge 3 to the left lamella edge 3'.
  • triangular elevations and depressions 4 and 4 ' run obliquely downwards from the right lamella edge 3 to the left lamella edge 3'.
  • triangular waves (elevations 4 and depressions 4 ') run from both lamella edges 3 and 3' approximately to the center line of lamella 2, where they meet.
  • the waveform described last is particularly suitable for slats that are not essentially flat, but z. B. are angled.
  • the waveforms 4 and 4 ′ described in FIGS. 5A to C can also be provided only over part of the width of the lamella 2. They can also be fixed in the manner shown in FIG. 4 in the form of a wave band 2 'on a flat or smooth lamella track.
  • 6a to e show five exemplary embodiments of blind slats according to the invention which are provided for a horizontal arrangement. These embodiments differ from those shown in FIGS. 1 to 5 in that the lamellae emerge from the plane and have alternating elevations and depressions over at least part of their length. 6a shows a first form of a lamella 20, in which elevations 23 and depressions 24 are formed between alternately inclined surfaces. The longitudinal edges 21 and 22 run parallel to one another.
  • the embodiment of a lamella 30 shown in FIG. 6 b has undulating elevations 33 which alternate with undulating valleys 34.
  • the longitudinal edges run parallel to one another.
  • the lamella shape 40 which is shown in FIG. 6c, has rectangular elevations 43, which are alternately arranged in a meandering manner with rectangular depressions 44.
  • the two longitudinal edges of the lamella are arranged parallel to one another.
  • the embodiment of a slat 50 shown in FIG. 6d is bent at an angle in its transverse direction, so that a roof-like slat shape is present.
  • the lamella surface 52 facing the viewer like the lamella 40, is provided with meandering alternating rectangular elevations 53 and depressions 54, while the lamella surface 51 turned away from the viewer has oppositely extending elevations 53 'and depressions 54' which are also arranged in a meandering shape.

  • the embodiment 60 shown in FIG. 6e finally consists of three longitudinal surfaces 61, 62, 63 angled in opposite directions, each of which has meandering alternating depressions 64, 64 'and elevations 66, 66' in the same way as for the lamella 50.
  • the angles designated 65, 65 'between the longitudinal surfaces 61 and 62 and 62 and 63 are obtuse angles and are also in the range between 150 ° and 175 °.
  • the depth or height of the depressions and elevations of the lamellae according to FIGS. 6a-e is expediently made only small and can depend on the lamella width and material thickness. Just like what has been said for the embodiments of FIGS. 1 to 5, it applies to the embodiments of FIGS. 6a to e that such slats with elevations and depressions can be arranged alternately or in any order with flat sl
  • any suitable material for example plastic or aluminum, can be used to produce the lamella screens designed according to the invention shown in FIGS. 6 a to e.
