Definitions

  • the invention relates to a shading device that can be used in particular as a sun visor for windows.
  • Such shading devices can be mounted both on the inside of the window and on the outside of the window.
  • roller blind is known in which both ends of the roller blind are jointly attached to the winding shaft.
  • the roller blind web forms a loop below the winding shaft in the fully extended state, which divides the roller blind web into two roller blind web sections.
  • the roller blind sections are fastened to the winding shaft in such a way that each roller blind section is guided from another side around the winding shaft to the fastening point.
  • the roller blind of the known roller blind has areas of higher light transmission which alternate with areas of lower light transmission arranged in between.
  • This regulation takes place by rotating the winding shaft, whereby the two roller blind sections are moved relative to one another, because when the roller blind is extended to the maximum, for example when the fastening point of the two roller blind sections is exactly at the top, the rotation of the winding shaft causes one roller blind section to be unwound further from the winding shaft while the other roller blind section is wound up by a corresponding amount.
  • the relative movement of the two roller blind sections shifts the areas of high and low light transmission of the two sections against each other and thus causes the change in the light transmission of the roller blind.
  • the light transmission can only be regulated when the roller blind is extended to the maximum.
  • relative movement between the roller blind sections is no longer possible. This state begins when one of the two roller blind sections is wound up for at least one handling on the winding shaft. From this setting up to the fully retracted state, the relative position between the roller blind sections can no longer be influenced by the user and only changes to the extent that one roller blind web section is relatively shortened compared to the other because of the different winding diameters.
  • the behavior of the known roller blind in this area is similar to the behavior of the known spring roller blinds, ie the brightness in a room can only be changed by extending the roller blind more or less.
  • so-called slat blinds which consist of a large number of narrow sheet metal slats stacked one above the other, are more variable.
  • the sheet metal slats are in rope-like suspension devices and by vertically shifting the strands of these rope ladders against each other, the slats can be pivoted against each other, so that a change in the amount of light transmitted is possible over the entire length of the extended slatted blind.
  • the structure of the slat blinds is relatively complicated, fragile, complex and difficult to clean.
  • the amount of light passing through can be varied due to the use of two film web sections which can be moved relative to one another and which can be printed differently or perforated, for example.
  • the amount of light passing through the shading device is maximum when the opaque areas from the light source lie congruently one above the other on both film web sections. Conversely, maximum darkening can be achieved if these opaque areas are shifted against each other.
  • the main advantage of the new solution is its simplicity.
  • the arrangement is no more complicated than, for example, spring roller blinds, but on the other hand it is Variability as known from lamella curtains.
  • the new shading device is also advantageous, for example in glass verandas or greenhouses, because the entire blind does not have to be retracted or extended to control the amount of light entering. A short relative movement between the film web sections is sufficient to achieve the desired effect.
  • the new shading device only needs to be retracted when complete light transmission is required.
  • the translucent areas are the same size as the opaque areas, in one setting light can only penetrate to the extent that it can pass through the opaque areas. Since the opaque areas are, depending on the embodiment, but not completely opaque, a certain amount of residual light remains.
  • the stroke required to vary the amount of light depends on how long the opaque areas are when viewed in the direction of relative movement. It is therefore advantageous to dissolve the translucent and the opaque area in a large number of sub-areas in order to be able to achieve the desired adjustment with a short stroke.
  • the opaque or less translucent areas can have any shape and are advantageously regularly or evenly distributed over the film webs in question.
  • the situation is particularly simple when the areas which are less or not translucent at all have a strip shape. They can, however, just as well be small square spots, which produce a uniform light at some distance from the shading device, which is almost independent of the structure or shape of the less translucent areas.
  • the roller blind can be made from a textile fabric, a plastic film or the like. consist. It is also conceivable to produce the blind sheet from a metal foil which is inherently opaque and to obtain translucent areas in this metal foil with the aid of openings.
  • the setting for the amount of light passing through the shading device is repeated every 5 cm to 10 cm.
  • roller blind sections can merge into one another at their end remote from the winding shaft or shafts, or they can each be attached to a falling rail, these falling rail parts being movable relative to one another.
  • roller blind sections merge into one another, they form a loop into which a cylindrical rod can be inserted, which either serves as a traction device due to its weight or can act on the separate tension members, for example in the form of springs.
  • the tension members can, for example, also be the tension straps or tension cables of a counter-tensioning system.
  • FIG. 1 shows a highly schematic, perspective view of a shading device 1 which has a winding shaft 2 which is rotatably mounted on stationary brackets (not illustrated).
  • the storage is such that the winding shaft 2 is rotatable about its longitudinal axis 3, for example with the aid of a drive device 4 in the form of a worm gear which can be driven by a hand crank 5 and whose output shaft 6 is coupled to the winding shaft 2 in a rotationally fixed manner.
  • a roller blind web 8 is attached at one end 7, the width of which corresponds approximately to the length of the winding shaft 2.
  • roller blind web 8 leads downward from the winding shaft 2, where it forms a loop 10, and from there upwards to an anchoring rod 12, which is also held stationary just below the winding shaft 2.
  • the rod 12 is connected in a known manner to a corresponding end 13 of the roller blind 8.
  • cylindrical rod 14 the length of which corresponds to the width of the roller blind web 8 and which, for example, can be provided on the end side with collar disks which are not illustrated in any more detail and which project radially beyond the outer circumferential surface of the cylindrical rod 14.
  • the cylindrical rod 14 consists of a material with a relatively large specific weight and thus serves both as a drop rail and as a deflection device for the roller blind web 8. This is divided in the loop 10 into two roller blind web sections 15 and 16, as it were, which are attached to the loop 10 merge into one another. If the weight of the rod 14 is not sufficient to keep the roller blind web 8 taut, additional pulling means can act on the rod 14.
  • the roller blind web 8 is made of an essentially translucent textile fabric, for example one Canvas.
  • This canvas is printed with a large number of less translucent, dark bars 17, between which translucent, strip-shaped partial areas remain, which have the same translucency as the raw material from which the roller blind web 8 is made.
  • the dark stripes or bars 17 run parallel to the winding shaft over the entire width of the roller blind web 8 and have the same height, measured in the longitudinal direction of the roller blind web 8, that is to say to the axis 3 of the winding shaft 2, as the translucent strip-shaped partial regions 18 delimited between them.
  • roller blind web 8 is almost completely unwound from the winding shaft 2.
  • the two roller blind sections 15 and 16 are spatially one behind the other, their distance approximately corresponding to the diameter of the cylindrical rod 14. Due to its own weight, this keeps the two roller blind sections 15 and 16 taut.
  • a light source based on FIG. 1, is located behind the shading device 1, ie on the side facing away from the viewer, specifically on a straight line that is perpendicular to the vertical plane defined by the roller blind section 16 stands and which passes approximately through the middle of this roller blind section 16.
  • the less translucent strips or bars 17 cast shadows with almost the same width on the back of the roller blind section 16, ie the side of the roller blind section 16 adjacent to the roller blind section 15.
  • the light passes through the more translucent strip-shaped ones Areas almost unobstructed or only slightly weakened.
  • the light which passes through the translucent sections 18 of the blind sheet section 15 can also pass through the blind sheet section 16 unhindered. Since the strips 18 are as wide as the strips 17, about half of the light passes through the shading device 1, compared to a situation in which the shading device 1 is retracted.
  • This maximum permeability of the shading device 1 is shown in the case described in FIG. 1.
  • the blind web section 16 facing the viewer is either raised or lowered to a certain extent, which means that the shadows created by the opaque areas 17 migrate on the blind web section 16 and reach the translucent partial areas 18 of the blind web section 16 .
  • little light passes through the shading device 1.
  • the opaque subregions 17 of the light source are used to achieve the maximum glare
  • Light source adjacent film web section 15 are no longer at the same height as the translucent areas 18 of the film web section 16, which lies away from the light source, but are accordingly offset against it.
  • the user of the new shading device 1 can change the amount of light passing through the shading device 1 in almost any desired extended position, the lower edge of the shading device 1 rising or falling slightly.
  • the operation of the new shading device 1 is thus as simple as the operation of a normal roller blind, but offers the convenience of a slat blind without its complexity.
  • the user winds the roller blind web 8 onto the winding shaft 2 as far as possible using the hand crank 5.
  • the lower edge of the shading device 1 is then located corresponding to the thickness of the cylindrical rod 14, which bears against the circumference of the bale wound on the winding shaft 2, below the winding shaft 2.
  • the two roller blind sections 15 and 16 have variable lengths, which depend on how far the shading device 1 is extended.
  • the two roller blind sections 15, 16 are merged in the area of the loop 10 and the position of this loop 10 depends on how much roller blind sheet 8 has been unwound from the winding shaft 2.
  • FIG. 3a and 3d show a selection of the different types of printing for the roller blind web 8 or the roller blind web sections 15, 16.
  • a checkerboard pattern is printed on the carrier material of the roller blind web 8 or produced by weaving from light and dark threads, the less translucent areas have the shape of small squares that are limited on the sides by small squares with good translucency.
  • Fig. 3b shows an embodiment when the roller blind is formed by a metal foil which is inherently opaque. In the case of a metal foil, the light transmittance is produced in that the foil is provided with holes 35.
  • the less translucent areas are triangular and have a length like the fully extended blind web section 15 or 16.
  • the height of these isosceles triangles is parallel to the longitudinal extent of the blind web sections 15, 16.
  • these triangles are located 36 obliquely, here also a modulation of the amount of light passing through the shading device 1 is possible.
