Definitions

  • the present invention relates to a roller shutter having a plurality of fins which are movable from a close-fitting position for complete dimming to a slightly extended position for a partial incidence of light.
  • a roller shutter which has a plurality of fins, which have at its upper edge a hook element and on its underside a counter hook.
  • the hook is formed from a web on which a plurality of openings are recessed. If the slats hang loosely together, the openings are in the visible range and thus allow a light incidence. Above a building opening, the slats can be wound on a roll, wherein they are hinged in the region of the hook and the counter hook.
  • the slats When unwinding, the slats are pulled apart by their own weight and a building opening is partially shadowed by the roller shutter, then completely translucent. Then the slats are initially placed in the lower area, up to the top of the building opening on each other, until the building opening is shaded opaque.
  • FIG. 1a to d the operation of such a shutter is shown schematically.
  • a building opening 1 ' is covered by a roller shutter 2', wherein the slats 3 'of the shutter 2' are first moved from top to bottom in their translucent position.
  • the shutter is completely lowered and forms a translucent surface 4 'from.
  • the roller shutter is lowered further (FIG. 1c)
  • the lamellae begin to push together to form an opaque surface 5 'until the position shown in FIG. 1d is reached at which the lamellae form a completely opaque surface 5' and thus close the building opening. It is not possible to opaque only an upper part of the building opening or to change the light incidence by the slats in the translucent position.
  • the lamellae are connected to one another via spring elements and the spacing of the lamellae from one another is variable. This allows the user to choose whether to keep the slats in an opaque position, or in a more or less translucent position, so that the light can be controlled.
  • a building opening may be only partially closed with lamellas, which are then arranged opaque or translucent.
  • a pulling mechanism is provided to pull apart the slats against the force of the spring elements.
  • the pulling mechanism is designed so that it is preferably adjustable by means of an electronic control synchronously to the height adjustment and asynchronously pulling apart the slats.
  • the desired position of the slats can be adjusted by mechanical means.
  • the distance between the slats is infinitely variable and the set distance can be fixed.
  • the distance between the slats can be adjusted between a closed position up to several centimeters opening gap, which is a high Level of adjustment guaranteed.
  • the lamellae form slots in an extended position, wherein the slots preferably extend over the entire width of the lamellae for a uniform appearance.
  • the spring force of the spring elements is dimensioned such that it is greater than the weight of the blades of the roller shutter.
  • the spring force of all spring elements may be the same or it may be used in the upper region of the slats, where a higher weight by the underlying slats is provided stronger spring elements than in the lower area, where only lower weight forces act.
  • the number of spring element per blade also vary to obtain a total of equal force ratios.
  • a plurality of spring elements can be arranged distributed over the length of the slats to ensure a form-fitting abutment of the slats.
  • the roller shutters can also be made very wide.
  • a spring element bears against an upper edge of a lamella and passes through an opening in a lower edge in a lamella arranged above it and is suspended on a holding element there.
  • a spring-mounted Lamellenbehang can be realized in a simple manner, the spring elements are largely not visible.
  • the lowermost blade is preferably coupled to a drawbar which is connected to a pulling mechanism for pulling and fixing the blades. This can be changed by the movement of the drawbar, the distance between the slats with each other.
  • the slats are designed according to a preferred embodiment as an open hollow profile, wherein a filling for better insulation can be arranged in the hollow profile. To a certain light control through the slats too can reach this have a plane inclined to the slat curtain leg. This allows the light to be reflected in a desired direction. Further, a slot for mounting the spring elements may be formed between the leg and the other part of the slats.
  • the spring elements may be made of metal, preferably a spring steel, plastic and / or rubber.
  • the roller shutter may include a controller which regulates the distance of the slats and their position depending on a light radiation. For example, in the absence of light, the shutter can be moved to the opaque position, because then no light enters the building anyway and a closed position of the shutter is desired. At dawn of the day, the shutter can then be opened automatically, in the case of sunlight, the slats can be brought into a translucent position, which can be selected depending on the intensity of sunlight.
  • FIGS. 2a to d A roller shutter according to the invention is shown schematically in FIGS. 2a to d.
  • a shutter 2 is mounted on a building opening 1, which forms an opaque surface 5 in FIG. 2 a and a translucent surface 4 in FIG. 2 b, which extends over only a part of the building opening 1.
  • the shutter 2 is positioned so that it completely covers the building opening 1 and a translucent surface 4 is formed.
  • the roller shutter is arranged such that it forms an opaque surface 5 within the building opening 1. While the positions in FIGS. 2b, c and d can be achieved with a roller blind of the prior art, the arrangement according to FIG. 2a with an opaque surface 5 in only an upper part of the building opening 1 is not possible. Furthermore, with the object of the present invention, the light incidence can be changed by the translucent surface 4, which is also not possible in the prior art.
  • FIG. 3 shows a roller shutter 2, as it can be mounted on a building opening 1. It comprises an upper drawbar 6, on which a plurality of lamellae 3 are suspended, wherein the lowermost lamella 3 is coupled to a lower drawbar 7.
  • the individual slats 3 are spaced apart from each other and thus in a translucent position.
  • the slats 3 are held together by spring elements 8 to each other, wherein the spring force of the spring elements 8 is dimensioned so that it is greater than the weight of the underlying slats 3 and the drawbar 7.
  • the position shown in Figure 3 is achieved because a with the lower drawbar 7 coupled pulling mechanism pulls the drawbar 7 down and fixed in a predetermined position.
  • 3 slits 9 are formed between the slats, which extend over the entire width of the slats 3.
  • the width of the slots 9 can be variably adjusted, depending on which tensile forces are applied to the lower draw bar 7 via the pulling mechanism. Depending on the design of the spring elements 8, the distance between the slats 3 from a closed opaque position to several centimeters distance between the slats 3 amount.
  • the lamellae 3 are infinitely adjustable via the pulling mechanism, so that depending on the incidence of light, the desired position of the lamellae 3 can be adjusted.
  • the spring elements 8 may be configured uniformly, so that the same spring force acts. Especially with larger shutters 2 different strength spring elements 8 can be selected because the upper blades 3 are more heavily loaded by a weight force through the underlying slats 3. This could lead to the fact that the distances between the slats 3 are different in size. If the slats 3 are formed very easily and the force of the spring elements 8 is very large, the weight of the slats 3 is hardly significant and the slots 9 are approximately equal over the height of the shutter 2.
  • FIGS. 4a and 4b show a side view through a roller shutter 2, wherein in FIG. 4a the lamellae 3 are arranged pulled apart so that a light-permeable slot 9 is formed.
  • the fins 3 are preferably made of a bent metal sheet, such as aluminum or steel, and connected to each other via spring elements 8.
  • the spring elements 8 can be made of a spring wire with a diameter between 1 to 2 mm, wherein each spring element 8 is connected to both an upper and a lower plate 3. In the lower lamella 3, the spring element 8 rests against an upper edge and engages with a central region an opening in a lower edge of the overlying lamella 3. In this central region, the spring element 8 is suspended on a holding element 15.
  • the slats 3 are formed as open hollow profiles and comprise a leg 12 which is arranged inclined to the plane of the slat curtain formed by the slats 3, for example at an angle between 10 ° and 30 °. Between the leg 12 and the remaining part of the blade 3, a slot 11 is formed through which the spring elements 8 can be easily mounted.
  • the lamellae 3 are substantially rectangular in the form of a hollow profile, wherein an upper edge of a lamella 3 forms a contact surface 14 and a lower edge of a lamella 3 of a contact surface 13. If the contact surfaces 13 and 14 touch each other, the shutter 2 is opaque, so opaque formed.
  • the contact surfaces 13 and 14 may also be coated or profiled, for example in the manner of a tongue and groove arrangement, to ensure a particularly tight closure.
  • a shaft may be arranged on which the Slats 3 are wound, the blades 3 are rotatable relative to each other.
  • spring elements 8 are shown made of metal, of course, other spring elements, such as rubber, resilient plastic compounds or other springs can be used.
  • the lamellae 3 can be made of aluminum sheet, for example, whereby steel sheets, extruded profiles made of plastic or aluminum can be used.
  • the slats 3 are shown suspended from each other. It is also possible to provide lateral spring elements on the slats 3. As a result, the appearance is improved because the spring elements are no longer arranged in the visible range.
