Definitions

  • the invention relates to a Venetian blinds with Venetian blind, slat-like roller shutter slats, which are articulated at their upper areas with articulated links of a pull chain and at their lower areas with articulated links of an adjustment chain and laterally guided in stationary guide profiles.
  • the connecting axes of the adjustment chain links with the roller shutter bars being spaced apart from the plane in which the articulated axes of the adjustment chain links lie.
  • roller shutter is known for example from EP-A 382 172.
  • EP-A 382 172 Such a roller shutter is known for example from EP-A 382 172.
  • roller shutters it is desirable that on the one hand they can be rolled up in the roller boxes without problems and as space-saving as possible, and that on the other hand the replacement of non-adjustable roller shutters already present in buildings by blinds is possible without major changes.
  • the existing guides do not have to be moved or replaced by others with larger dimensions.
  • roller shutters should consist of as few individual parts as possible and be inexpensive to manufacture.
  • the roller shutter known from EP-A 382 172 has two disadvantages in this respect. First of all, it is necessary that the guide profiles must have a certain distance from the window or door frame or the like, since the roller shutter slats are not only pivoted outwards when the blinds are closed, but also protrude inwards over the guide profiles by a certain amount , which is related to the special arrangement of the pivot bearings of the roller shutter slats. Second, the roller shutter according to EP-A 382 172 consists of a relatively large number of individual parts, which has a disadvantageous effect on the production costs.
  • the object of the invention is therefore on the one hand to provide a roller shutter that does not have an inward, i.e. has movable parts for the window or for the door or the like and which, on the other hand, are simple and inexpensive to produce
  • roller shutter should be able to be rolled up in the roller box without any problems and with as little space as possible.
  • the pivot axis of the roller shutter slats are aligned with the articulated axes of the pull chain links and the adjustment chain links and can be moved to the upper edge of the roller shutter slats, the upper area of the roller shutter slats is no longer pivoted inwards when the roller shutter slats are louvred.
  • Another advantage that results from the invention is that the alignment of the roller shutter slats by the alignment of the axes in the non-blinded state of the roller shutter together with the associated pull chain links and adjustment chain links and consequently very space-saving and problem-free can be rolled up in the roller box.
  • Another advantage is that for the pivot axis of the roller shutter bars on the pull chain links and the connecting joint of two adjacent pull chain links, a single bearing axis, i.e. a single bearing pin can be used, which reduces both the number of components of the roller shutter and their manufacturing costs.
  • a preferred embodiment of the invention is characterized in that grooves are provided in the roller shutter slats in the region of their ends in the region of their ends, in which the adjustment chain links are in the non-blinded state of the roller shutter in the are essentially completely included.
  • Such a groove is easy to produce in the roller shutter slats, for example by milling out the corresponding area of the roller shutter slat, and a stable and space-saving receptacle is created for the pull chain links.
  • roller shutter bars are guided in the stationary guide profiles via the pull chain links.
  • the roller shutter slats can simply be cut straight at their ends and the immediately adjoining chain links form the guide in the guide profiles.
  • Another possibility according to the invention is that the area of the roller shutter slats in which the pivot axis of the roller shutter slats is received is lengthened in the longitudinal direction of the roller shutter slats and that the roller shutter slats are guided in the stationary guide profiles via this extension and the pull chain links .
  • This embodiment offers an even more stable guidance of the roller shutter bars in the guide profiles, since their extensions engage directly in the guide profiles.
  • a particularly preferred embodiment of the invention is characterized in that the pull chain links and / or the adjustment chain links are made from extruded profiles the roller shutter slats can be adapted so that a continuous, essentially smooth surface of the roller shutter is formed without interruptions.
  • the production of the tension and adjustment chain links from extruded profiles also offers a considerable cost advantage, since extruded profiles are inexpensive and easy to process further.
  • At least one center support chain is provided, which is designed essentially like the pull chains, so that the roller shutter slats, in particular when they are blinded, ie are swung out, do not sag due to their own weight, which on the one hand is unattractive and on the other hand can lead to malfunctions.
  • the invention can preferably be developed in such a way that a number of grooves corresponding to the number of center support chains is provided on the side of each roller shutter rod facing away from the outer facade, in which the chain links of the center support chains are essentially completely accommodated.
  • the middle chain is not visible in this case from the outside when the roller shutter is closed and also hardly disturbs when the roller shutter is cleaned from the inside.
  • the pull chain links, the adjustment chain links, the middle support chain links and / or the roller shutter slats are made of metallic material, preferably aluminum.
  • roller shutters or parts of roller shutters are often made from plastics. However, these are exposed to sun protection systems, very high UV radiation values and air pollutants, heat and cold, which greatly reduces the lifespan of plastic parts.
  • metallic materials usually have higher strength values than plastic parts at often lower costs, and the tool costs for producing the parts in plastics are also usually much higher.
  • An extrusion tool for example, costs about 10% of a plastic tool.
  • the inventive simple design of the individual parts of the roller shutter makes it possible to manufacture all parts from metal, preferably from extruded or roll-formed metal, whereby the plastic parts with the mentioned disadvantage can be replaced.
  • Fig. 1 is a side view of a roller shutter in the blind Represents state according to arrow I in Fig. 4,
  • FIG. 2 shows a section through the blinds in the direction of arrow II in FIG. 4,
  • FIG. 3 shows a section through the blinds in the direction of arrow III in FIG. 4,

It should be noted that 4 by I, II and III it is shown how the cuts according to FIGS. 1, 2 and 3 are made, but in FIGS. 1 to 3 the roller shutters are in the blind and in FIG. 4 the roller shutters are not blinded, ie closed. Condition is shown.
  • a pull chain for the roller shutter is formed from pull chain links 21 which are connected to one another via axes 16.
  • the pull chain links 21 have a bore at one end and an elongated hole 35 at their other end, the function of which will be explained later.
  • the axes 16 also form the pivot axes for the roller shutter bars 14, which are connected in an articulated manner to the tension chain links 21 via the axes 16.
  • roller shutter bars 14 have a part 17 projecting in the region of the axis 16 and that this projecting part 17 and the pull chain links 21 are guided in a schematically indicated stationary guide profile 31.
  • a groove 24 is provided in the roller shutter bar 14, the course of which is also shown in FIG.
  • pull chain links 23 forming a pull chain are received, which are connected to one another via articulated bolts 30.
  • the adjustment chain links 23, like the pull chain links 21, have a bore at one end and an elongated hole 36 at their other end.
  • the adjustment chain links 23 also have a bore 33 which is not in the common plane of the articulated bolts 30 and is preferably spaced from this by 4 to 5 mm. Each chain link 23 is by a connecting bolt
  • roller shutter bar 14 is included in the roller shutter bar 14.
  • roller shutter exceeds a certain width, you can one or more center support chains can be provided, which are composed of chain links 29, the shape of which essentially corresponds to the shape of the pull chain links 21, with the exception that their width is less seen transversely to the longitudinal axis of the roller shutter bar 14.
  • the roller shutter bars 14 have a groove 53 on their rear side 25, ie the side facing away from the outer facade, the course of which can also be seen in FIG. 7.
  • the groove 53 and the chain links 29 are designed such that the chain links 29 are essentially completely received in the groove 53 on the rear side 25 of the roller shutter bars 14.
  • the same also applies to the adjusting chain links 23 on the front side of the roller shutter bars 14, so that in the roller shutter according to the invention there are no parts projecting beyond the outer contour of the roller shutter bars 14 if the roller shutter is not blinded.
  • the axes 16 of the pull chain links 21 as well as the axes 30 of the adjusting chain links 23 and the axes 37 of the middle support chain links 29 are in alignment when the roller shutter is not blinded. This has a very important advantage when the roller shutter is wound onto a shaft in the roller box. Because all the axes 16, 30 and 37 mentioned are in alignment, the individual roller shutter bars 14 and the corresponding chain links 21, 23, 29 can be pivoted about a single, common axis, which means that the roller shutter is completely free of tension is guaranteed and, on the other hand, there are no swinging-out parts of the roller shutter bars 14 which would increase the winding diameter when the roller shutter is wound up.
  • the connecting axes 32, via which the adjustment chain links 23 are connected to the roller shutter bars 14, are not in the common plane of the hinge pin 30 of the individual adjustment chain links 23 but are offset to the outside, ensures that the roller shutter bars 14 without problems and additional Auxiliary devices can be blinded if the adjustment chain is pulled upwards or held there and the roller shutter is further lowered, as is known, for example, from EP-A 382 172 is that a lever arm is formed between the connecting pin 32 and the upper joint pin 30 of the adjusting chain link 21 on each roller shutter rod 14, whereby the pivoting out of the roller shutter rods 14 is ensured.
  • the chain links 21, 23 and 29 are made from plate-shaped parts and, for example, are punched out of sheet steel.
  • FIGS. 9 to 14 A further embodiment of the invention is shown in FIGS. 9 to 14, wherein the pull chain links 40, the adjusting chain links 41 and the middle support chain links 42 are made of extruded profiles, for example of aluminum.
  • the roller shutter slats 14 of this embodiment are essentially the same as the roller shutter slats of the embodiment according to FIGS. 1 to 4, with the one exception that the extension 17 with which the roller shutter slats 14 protrude into the stationary guide profiles 31 is not present and the roller shutter bars 14 thus have a straight end.
  • FIGS. 11 and 12 show an adjustment chain link 41 made from an extruded profile, which has a fork-shaped recess 43 on one side and a shoulder 44 at the other end.
  • An elongated hole 36 is arranged in the extension 44 and bores 46 are provided in the webs 45 delimiting the fork-shaped recess 43.

Abstract

Un volet roulant à jalousies comprend des barres (14) similaires à des lames orientables à la manière de jalousies reliées par leur zone supérieure aux maillons (21, 40) articulés d'une chaîne de traction et par leur zone inférieure aux maillons articulés (23, 41) d'une chaîne d'ajustement. Ces barres (14) du volet roulant sont latéralement guidées dans des profilés fixes de guidage (31). Les axes de liaison (32) entre les maillons (23, 41) de la chaîne d'ajustement et les barres (14) du volet roulant sont espacés par rapport au plan dans lequel sont situés les axes d'articulation (30) des maillons (23, 41) de la chaîne d'ajustement. Les axes (16, 30) des articulations qui relient entre eux les maillons (21, 40) de la chaîne de traction et les maillons (23, 41) de la chaîne d'ajustement, ainsi que les axes de pivotement (16) des barres (14) du volet roulant, sont mutuellement alignés lorsque le volet roulant n'est pas utilisé comme jalousie. On peut ainsi enrouler sans problèmes le volet roulant dans un espace réduit et l'utiliser comme jalousie sans accessoires particuliers.
