Definitions

  • the invention relates to a device with a lamella and an elongated end element having external venetian blind and an adjusting device connected to the end element for lifting and lowering the end element.
  • the "low position” of an external venetian blind is understood to mean the position of the latter in which the store and in particular its end organ assume the lowest possible position.
  • the “high position” of the venetian blind is understood to mean the position of the venetian blind in which the store and in particular its end organ are in the highest possible position. In the “intermediate positions” of the external venetian blind it is then between the low and the high position.
  • Known devices have a venetian blind with slats and a rod-shaped end element arranged at the lower end of the venetian blind.
  • the known devices also have an actuating device for lifting and lowering the store and for pivoting the slats.
  • the actuating device has a rotatable shaft which is connected to the two ends of the end member via two elongate transmission members, for example formed by cords, bands, chains or toothed belts.
  • a known device is arranged at the window of a building and the venetian blind is in the high position, its slats are gathered. The shirred The lamellae and the end organ then extend over a height range which is normally about 40 cm to 60 cm. The store therefore often still covers part of the glazing of the window in the high position.
  • This has the disadvantage that the lighting of the areas of a building interior adjacent to the window, which are far from the window, is impaired.
  • the sun is shining in, for example, at least one computer screen or other interior space, it is often necessary to lower the stores to avoid glare from people staying in the space and to illuminate the space with artificial light. Lighting with artificial light requires energy and causes the rooms to heat up undesirably, especially in summer.
  • US Pat. No. 3,192,991 relates to a device with a frame and a venetian blind.
  • the frame has a metallic channel with a U-shaped cross section on both sides.
  • the store has slats, at the upper end an upper end organ ("head”) with a U-profile bar, at the lower end a lower end bar ("botton bar”) and belts, which according to FIGS. 1 and 2 apparently the upper end organ with the Connect the lower end bar.
  • a swivel device arranged in the U-profile bar can be actuated by means of a swivel cable in order to swivel the slats over the belts.
  • a first elevator rope has two parts deflected by rollers in the supporting channel of the frame, one end of which is connected to form a loop b and the other ends of which are attached to the U-section bar of the store. This can thus cover or release a window opening by lifting and lowering the end member arranged at its upper end and, in the lowered position according to FIGS. 3 and 4, can be sunk in a recess in the window lintel.
  • the invention is based on the object of eliminating disadvantages of the known devices with external venetian blinds and, during the day, of optimally illuminating an interior of a building with daylight and sunlight, which is located behind at least one window provided with a store, during the day. It should be possible in particular by suitable determination of the positions of the store that areas of the interior that are far away from the window or windows can be well illuminated with natural light and / or that even in strong sunshine at least one person staying in the interior is not blinded and can work on a screen or perform other activities without additional artificial lighting.
  • the invention further relates to a building provided with a device according to claim 9. advantageous Further developments of the facility and the building emerge from the dependent claims.
  • the end element and the slats of the external venetian blind can preferably be pivoted into different pivot positions by the adjusting device.
  • the end member and the slats can then be pivoted, for example, in the closed pivot positions, in which they are generally approximately perpendicular, touch each other in pairs and result in a maximum attenuation of light.
  • the end element and the lamellae can, for example, also be pivoted into the open, pivoted positions, in which they are separated from one another substantially horizontally and by gaps and allow a relatively large amount of light to pass through.
  • the end member and the slats can also be pivoted into intermediate pivot positions.
  • the external venetian blind can be arranged in such a way that the end element is in the low position near the lower end or edge of the glazing, preferably below this or at most a little above of the lower glazing end or edge.
  • the external venetian blind then releases completely at least most of the glazing, namely at least one area of the glazing extending from the end organ to the upper end of the glazing and, for example, the entire glazing.
  • natural light ie daylight or sunlight
  • the external venetian blind can be, for example, Intermediate position in which he partially or completely covers the lower area of the glazing - depending on the pivoting position of the end element and the slats - and releases the upper area of the glazing. It can thereby be achieved that on the one hand at least one person can protect against direct light radiation, for example, work on a screen without being dazzled, and on the other hand that enough light penetrates through the upper, free area of the glazing to allow the interior to be reflected and reflected in it / or to illuminate scattered, diffuse light sufficiently so that the person can work and / or read, for example, without additional artificial lighting. The same applies to people who do not work on a screen but perform other activities. When the external venetian blind is in the up position, it can partially or completely cover the entire glazing, depending on the pivoting position of the end element and the slats.
  • a wall 1 of a building which can be seen in part in FIGS. 1 and 2, has at least one window opening which is delimited at the bottom by a window parapet 3 and at the top by a lintel 5.

The slats can therefore not be moved, at least in the high position of the store, either by wind or by direct manual gripping of the slats. Since the braking members 55 can only be displaced with a relatively large amount of friction in the second profiled bars, they generate an undesirable pivoting of the end member and prevent torque that prevents the end member and the disks attached to it from being pivoted by the action of wind.

  • the end element of the external venetian blind can then be dimensioned so wide that it lies on the window parapet 3 at the mouth edges of the recess 11 in the low position of the store, covers the recess 11 and closes it more or less tightly and therefore additionally as an adjustable closure element for closing the recess 11 is used.
  • the braking body of the braking member can be provided with a rack-like leg in the same or a similar manner to a slide 40 and can be positively connected to the end sections of a brake toothed belt.
  • the braking members may also be provided with at least one spring-loaded, movable and / or deformable brake shoe arranged at a suitable point.
  • Each brake toothed belt wraps around a brake gear at the top and bottom of the guide.
  • the upper or lower brake gears are connected via a shaft to an electrically controllable, electromagnetic braking and / or blocking device and can optionally be released or braked by this and at least approximately blocked.
  • the brake bodies can be displaced by the sliders, the friction of the brake body, brake toothed belt and brake gearwheels causing the end member to pivot Slats made possible by moving the slider. If the braking and / or blocking device brakes and / or blocks the brake gears connected to it, the braking bodies are held practically immovably. This practically prevents the end member and the slats from swiveling due to direct, manual gripping of the end member or a slat even when a great deal of force is used, and increases the protection against break-ins that can be achieved by the venetian blind.
  • the external venetian blind can be designed as an organ for reflecting and deflecting light and can have, for example, slats, of which at least one surface or broad side is reflective, in order to reflect sunlight and out of the outside or surroundings of a building through a window into one Redirect interior of building.
  • the slats can then be designed, for example, in such a way that the light reflected into the interior is diffusely scattered and people who are in the interior do not dazzle.
  • the lamellae can either be opaque or translucent to such a degree that they let diffuse light through but at least largely prevent glare from people through the transmitted light.
  • the swivel positions of the slats can then be adjusted by one person and / or automatically to the position of the sun.
