Definitions

  • the present invention is based on a louvre window with the features specified in the preamble of claim 1, which are known from document DE-A-33 43 538.
  • the side walls of the frame side parts which form the recess for the strip-shaped seal, consist of their own profile parts (so-called "counterparts") and the seals extend over most of the width of the side walls.
  • This ensures a good seal between the lamella brackets and the side parts of the frame.
  • the construction of the frame side parts is relatively complicated and the counterparts made of metal profile parts form thermal bridges between the outer and inner frame parts.
  • a relatively high force is also required to rotate the slats because of the large contact surfaces between the slat holders and the strip-shaped seals.
  • the louvers are double-walled hollow profiles made of transparent plastic, such as polycarbonate.
  • a louvre window with simple glass louvres and a brush-like sealing strip, which sits in a T-shaped groove of the side part consisting of a one-piece aluminum continuous casting hollow profile, is known from document DE-B-15 09 775.
  • a louvre window is known in which a push rod which is slidably mounted in a side part of the frame is coupled with pinions which sit on the bearing journals of lamella holders, each via an individually adjustable rack piece.
  • the present invention achieves the object of simplifying the construction of the frame side parts and their production and of improving the thermal insulation between the outside of the frame and the inside of the frame by means of the characterizing features of patent claim 1.
  • the louvre window has a rectangular frame 10 which consists of an upper cross part 12, a lower cross part 14 and side parts 16, 18.
  • slats 20 are rotatably supported by slat brackets 22.
  • the frame parts each consist of an outer metal profile 24 and an inner metal profile 26, which are connected to one another by webs 28, 30 made of a heat-insulating material, in particular plastic, for example polyamide.
  • the metal profiles 24, 26 are extruded aluminum profiles.
  • the webs 28, 30 have thickened, in particular dovetail-shaped ends, which sit in corresponding inwardly widening, in particular dovetail-shaped grooves 32.
  • the dovetail-shaped grooves are each formed by a surface of a strip-shaped projection 34, which is located on the outside of a cavity enclosed by the webs 28, 30, and opposite side walls of projections 36, which are located on the inside of the cavity enclosed by the webs .
  • the webs each have a raised central part with lateral projections 38, which together with corresponding opposite parts of the projections 34 of the metal profiles each form an inwardly widening, in particular T-shaped groove 40.
  • Brush-like seals 42 are arranged in the grooves 40, which have a strip-shaped base, which is located in the groove, and bristles, which extend out of the groove to the opposite surface of the adjacent lamella holder 22.
  • the lamella holders are provided with bead-like elevations 44 which run in the longitudinal direction of the lamella holders and improve the seal on the one hand when the slats are closed and on the other hand there is little friction between the seals and the Ensure slat brackets when turned to the open position.
  • the inner metal profile 26 has a closed, box-shaped part, into which projects a part 46 with a C-shaped cross section, which serves to receive a self-tapping screw for fastening the frame cross parts.
  • a corresponding part 48 is arranged in the vicinity of the outer wall of the outer metal profile 24 at the same height as the part 46.
  • the inner metal profile forms on the side facing away from the window slats 20 a rectangular groove 50 in which a push rod is slidably mounted, which in turn forms an approximately C-shaped groove 54 on the outside, in which a rack piece 56 is fastened by screws 58, which meshes with a toothed segment 60 which sits on a bearing journal 62 of the lamella holder 22.
  • This part of the lamella drive device will be explained in more detail with reference to FIG. 7.
  • the journal of the slat bracket has a z. B. hexagonal cross section and is rotatably supported by a bushing 64, which is seated in a bore of the web 28.
  • the end of the bearing pin extends into a hexagon hole 66 of a cylindrical extension 68 of the tooth segment, which is rotatably mounted in a corresponding hole in the second web 30.
  • the free end of the toothed segment 66 has a coupling piece 70 with a hexagonal hole, which can be coupled to a corresponding coupling piece of an adjacent window unit by means of a hexagonal coupling pin, so that the lamellae of both window units can be actuated together.
  • the coupling can also be done by a mechanical or magnetic circuit coupling.
  • the lamella holders contain an essentially U-shaped holding part 72 with legs 74, 75 offset in the longitudinal direction with respect to one another (FIG. 3b).
  • positioning tabs 76 protrude from the bottom of the holding part 72, which, as shown in FIG. 3b, can be L-shaped. They engage in a chamber of the held lamella, as will be explained in more detail with reference to FIG. 4, and thereby fix the lamella in the longitudinal direction and, if appropriate, also in the transverse direction of the lamella holder.
  • An elastic, strip-shaped insert 78 (FIG. 2) is preferably arranged in each lamella holder, which has punched-out recesses for the positioning tabs 76 and seals the lamella in question on the end face and absorbs different thermal expansion of the frame and lamellae.
  • Figure 4 shows a vertical section through part of a louvre window according to the invention.
  • a part of the lower cross part 14 can be seen, as well as an adapter 80 which is inserted into the grooves 40 of this cross part and which has the shape of the upper end of a window lamella and is provided with a seal 82 which has a paisley-shaped cross section, ie a cross section in shape of a curved drop, and a window slat 22, which sits in a slat holder, from which the end faces of the legs 74, 75 can be seen.
  • the window slat 22 is a hollow profile made of plastic, which has transverse webs 84 and a longitudinal web 86 on the inside and is closed except for the ends seated in the slat holders.
  • the upper longitudinal wall has a part 88 which slopes obliquely from the outside inwards and a narrow, box-shaped, cross-sectionally, upwardly extending extension part 90 which has an outwardly projecting claw-like part 92 which forms a groove for receiving a seal 94 which forms the has the same cross section as the seal 82.
  • the lower longitudinal wall is complementarily symmetrical and accordingly has an extension part 90a on the outside with a seal 94a and a flat part rising inwards.
  • the seals 82, 94, 94a can consist of transparent elastic plastic, so that they do not attract attention.
  • FIG. 5 shows an opaque window lamella 22b, the front and rear walls of which are each formed by an extruded aluminum profile 96a, 96b.
  • the profiles 96a are connected by heat-insulating webs 98 made of plastic and are closed on the upper and lower longitudinal sides by plastic profile strips 100, which have a similar configuration on the outside as the upper and lower longitudinal sides of the lamella 22 according to FIG. 4 and how these are provided with similar seals 102 are.
  • the outside of the window is on the right, in Figure 4 on the left.
  • FIGS. 6 and 7 show a side view and a partially sectioned top view of the lamella drive, which has already been explained with reference to FIG. 2.
  • FIGS. 8 to 11 show further details of the lamella drive, namely the drive for the push rod 52.
  • This is connected at the lower end to a rack plate 102 into which a gearwheel segment 104 engages, which via a hexagon intermediate piece 106 has a hexagon socket 108 is coupled, which is rotatably mounted in a circular recess of the inner metal profile 26 of the relevant side part and is driven by a hexagon socket hollow shaft 110 which extends through the lower cross part.
  • the intermediate piece 106 is connected to the toothed segment 104 and the bushing 106 by pins 112, which are accessible through corresponding holes, not shown, in the metal profile 26.
  • the hollow shaft 110 is driven by a worm gear, which contains a gearwheel 114 coupled to the hollow shaft 110 and a worm 116 driving the latter, which is seated on a drive shaft 118, which is mounted in the lower cross part 14 , extends transversely to this and has an outwardly extending end which can be driven in a manner not shown by a crank or by an electric motor.
  • a second hollow shaft 110a can also be coupled to the gearwheel 14 for driving a second push rod arranged in the other side part.
  • the window has a relatively large width and the hexagon socket hollow shaft 110 is correspondingly long, the latter can be stored between the gear 114 and the gear segment 104 by one or more intermediate bearings of the type shown in FIG. 11.
  • the intermediate bearings are fastened in trapezoidal depressions on the inside of the webs 28, 30 by screws 122 and have cylindrical end faces for the hexagon shaft 110.
  • FIG. 12 shows two adjoining side parts 160, 180 of two louvre window units arranged next to one another.
  • the coupling pieces 70A, 70B face each other. They can be connected to one another for a common drive of the lamellae of the two window units by means of a hexagonal coupling pin 124 shown in broken lines.
  • a disengageable clutch e.g. a magnetic clutch, a dog clutch or the like may be provided.
  • FIG. 13 shows a cross section of a somewhat modified frame part, on the basis of which a preferred production method is to be described.
  • the frame part shown in FIG. 13 differs 2 in that the strip-shaped projections 34, which form a side wall of the dovetail-shaped groove for receiving the ends of the webs 28, 30, are weakened at their feet by a groove-like recess 128 (or in some other way) that a bending point is formed there.
  • the metal profiles 24, 26 are extruded or deformed after the extrusion in such a way that the projections are initially bent outwards in relation to the dovetail-shaped groove, as shown in broken lines at 34a in FIG. 13 at the top left.
  • the ends of the webs 28, 30 can then be easily inserted into the dovetail-shaped grooves 32 opened in this way and then securely fixed by bending and pressing the projections 34a.
  • the pressing can take place in a simple manner in that the profiles 24, 26 with inserted webs 28, 30 are passed between two rollers, which exert pressure in the direction of the arrows 130 on the bent projections 34a and press them into the position 34 drawn in the solid line.
