Definitions

  • the present invention relates to a solar shading with a slat frame, the opposite, extending over the length of the sunblind comprises extending profiles and these interconnecting cross braces, and a cover layer attached to the slat frame.
  • Slats as a sun protection element are known from the prior art. On Example of this is disclosed in document FR 75 31456.
  • the slat described here consists of preformed steel sheets, which are pressed at the ends with profiled strips are and whose interior is filled with a plastic foam. These slats are relatively heavy due to their metallic material and require a heavy support structure to hold the slats and in their angular position to adapt to the prevailing lighting conditions.
  • the sunblind of the beginning mentioned type characterized in that the cover layer of a stretchable Folienund / or Fabric material consists of holders and at least one profile and / or at least one transverse strut is held stationary under prestress.
  • plastic films, fiberglass fabric or comparable material to be used, which on the one hand compared to metallic Materials is extremely light, but also in thermal Fluctuations remain dimensionally stable and no wrinkles, sags or in the wind flutters.
  • the thin material allows a design that still allows light to fall through can.
  • the film or the fabric may be so coated or equipped that certain wavelengths are filtered out of the light. That way is it is still possible to let enough light into the building, though the heat radiation is filtered out by the sunblinds.
  • the cover layer So lies in terms of their translucency between metal blades and Glass fins, but both are heavier.
  • the light transmission is influenced, for example, by the mesh size of the fabric, the choice of materials and mixture and a possible coating.
  • the lamellae according to the invention are inexpensive to produce.
  • the holding structures can be essential be carried out more easily and cost-saving.
  • the dimensions and properties the sunscreen blades according to the invention can very easily on the adapted to individual needs. With the system are different Geometries, shapes and colors can be displayed.
  • a holder As a holder, various elements come into consideration. So is as a holder in particular provided a support surface on which the cover layer rests under pretension. The bias causes a frictional engagement between the cover layer and Support surface, whereby the cover layer is fixed in position. But it comes Other embodiments of a holder for the top layer into consideration, so For example, a terminal block, in which the cover layer is clamped non-positively is held, or a molded body connected to the cover layer For example, a clamping bead which can be inserted into a receiving opening, that thereby the cover layer after final assembly of the slat frame form-fitting is fixed in position under prestress.
  • sun protection device Generally with 1 is a sun protection device numbered, the several sun protection slats 2 has. These sunblinds 2 are in a supporting structure 3 and in various pivoting positions, as illustrated in Fig. 1, to convict. For this they are provided with an actuating linkage 4, over the they in an upright open position and in the direction indicated in Fig. 1 closed position to be transferred.
  • each sunblind 2 has a cross strut fifth with lateral profiles 6 or longitudinal edge profiles, are embedded in the grooves 7, which serve as a receptacle for the end pieces 8 and 9 respectively.
  • Cross struts 5 and profiles 6 form the lamellar frame 14.
  • end pieces 8 and 9 of a cover layer 10 can be used from a film material.
  • This topcoat 10 is formed as a tension track, so that they the cross strut 5 as a sun protection element spans.
  • the cover layer can be applied on one or both sides and be executed in one or more layers.
  • the cover layer 10 is preferably made of a translucent material, the one transmits diffused light, for example with a transmittance between 10 and 20%, which ensures glare protection.
  • the motor angle adjustment of the sun protection device 1 with a Sensor-based control can increase the lighting level in each office be regulated so that in interaction with artificial light consistent, glare-free Lighting conditions can be created.
  • the slats can also be moved individually per room.
  • cover layer 10 As material for the cover layer 10 all substances or combinations of substances come in Consider, due to their specific nature or processing, for example in a fabric, with overstretching are tensioned. This applies, for example for polyester or silicone, but also coated glass fiber fabric.
  • the Glass fiber fabric can be heated and coated with PTFE, as required several times, until the required parameters such as stiffness, tear resistance, weather resistance, Fire behavior, stretch and extensibility and translucency and Optics are fulfilled.
  • Spannhus is especially the burden with a tensile stress of importance, since this is the preferred in the concrete use Voltage is.
  • the flexible properties of the material used It makes sense to expose the material to tensile stress, as it causes it can be kept well in shape and position.
  • the cross strut 5 in Figure 2 has a central region 11, the profiles 6 after projecting beyond the top, and in the additionally still a spring element 12 are used can, which is indicated only schematically.
  • a spring element 12th can in the middle of the sunblind 2, the top layer 10 also in addition be biased, but in Fig. 2 for better clarity not shown in detail.
  • At least one of the end pieces 8 and 9 is as Clamping bead formed by the cover layer 10 in its position to the profile. 6 can be fixed.
  • the cover layer 10 is biased to a desired degree and in If necessary also re-tensioned via the spring mechanism 11 and 12. As in Illustrated embodiment, the cover layer 10 is pulled around the profile 6 around, so that the cover layer 10, the profile 6 partially bounded.
  • the boundary angle is in the embodiment about 170 °. Depending on the requirements in the application The boundary angle can also be larger or smaller. Moving around the cover layer 10 is evened out by a profile 6 or a transverse strut 5 the tension and presses the cover layer 10 on the support surface 15. In addition the voltage can be well introduced into the slat frame 14.
  • the lower flange 13 ensures that according to FIG. 2 by the bias of the cover layer 10 on the crossbar 5 no vertical loads are exercised.
  • a support surface 15 for the cover layer 10 serve the rounded outer contours of the profiles. 6
  • An additional support surface 15 forms in the embodiment of the central region 11th
  • the cover layer 10 of the corresponding film material can be the most diverse Requirements must be designed accordingly. So let's look at relative simply provide different, even multilayer film materials, the also replaced and replaced with built-in sunshade can be. This can be done with a relatively simple effort. So can also films for different seasons or in terms of design Measures find use, for example, different To realize lighting effects.
  • the profiles 6 have end receptacles 16, in which the cross braces 5 are inserted.
  • the Receivers 16 are preferably formed so that the crossbars 5 form fit fit into the 16 shots.
