It has a step-shaped cross-section and two displaceably arranged arms with outwardly facing surfaces. A cross-rib (16) is arranged perpendicular to the arms and connects them. The outer arm (12) is connected to the outer metal profile (14) and the inner arm (11) is connected to the inner metal profile (13). The outwardly facing surface of the inner arm forms a sealing surface, on which the lamellae (3) in the edge area press with their inner sides.

Description

The present invention relates to louvre windows for substantially vertical Facades with the features of the preamble of claim 1.

Louvre windows are for vertical facades as well as for roof areas generally known, the wall or roof surface of plate or Glass panes are formed. The majority of those known in the patent literature Slats are designed as swing windows, i. H. the pivot point of each Slats are located in the middle of the two long sides. On too only these slats are available on the market. Such windows are for example in DE 33 43 538 A1, EP 0 477 955 B1 or also EP 0 119 369 B1 described. From DE 44 29 471 A1 is a wall or formed from plates Known roof area, with the individual plates or panes of glass are arranged so that they overlap each other in the closed state and immediately adjoin each other. The holder of the plates or disks are with one end pivotally connected to a first profile. At the Bracket attacks an adjustment bracket, which has one end at its first end second profile is pivotally attached, which in relation to the first profile Is displaceable in the longitudinal direction. One of the two profiles takes the as a support Load the plates or washers while the other is opening and Closing the wall or roof surface serves. This can be done with a piston-cylinder device be connected, as is known from DE 44 32 024 A1. There the drive took place by means of one or more hydraulic devices. The Plates or glass panes are each on a swiveling toggle lever held.

The above not overlapping louvre windows and others on the market Known non-overlapping louvre windows have the weak points Seal transition between the vertical and horizontal side surfaces of the Slats opposite the slat window frame. Furthermore, they are individual lamellae in separate frames and the height of one determines number of slats limited by weight. Another The disadvantage is the complex assembly on site and the difficult replacement a lamella, for example in the event of damage.

The present invention is therefore based on the object of a louvre window to propose for essentially vertical facade surfaces, which with regard to the disadvantages mentioned above is improved.

This task is solved by a louvre window with the features of the main claim. Further advantageous configurations are the See subclaims.

The louvre window designed according to the invention has one in the frame inserted all-round seal, which essentially one has stepped cross-section. The seal is preferably made of rubber or a rubber-elastic material. The all-round seal thus ensures a higher level of tightness, since between the side parts and the There are no transitions in cross sections. Due to the stepped profile achieved that the one leg as a fully circumferential flat sealing surface for the Slats. The two legs with their outward-facing surfaces are arranged over a substantially perpendicular to the legs and connected this connecting crossbar. The outer leg is on that outer metal profile and the inner leg fixed to the inner metal profile, so that a further thermal separation between the Metal profiles is ensured. Furthermore, the louvre window points Slat brackets on the opposite pairs in the Side parts are movably mounted and with the pivot point of the slat on Attack the upper end of each slat and while opening the slat from the Fold out the window surface, the pivot point of the respective slat at Open with respect to the closed position downwards and from the seal walks away. This configuration ensures that the respective Slat is moved away from the sealing surface and folded outwards. At the Closing the slat then seals a peripheral edge area of the inner surface the lamella on the sealing surface of the connected to the inner metal profile Leg of the seal. This structure also allows the arrangement of a fly screen on the inside of the window opening, as the lamella at Opening did not get into this area.

To prevent water from entering between the inside of the slat and to avoid the seal on the inner metal profile is preferably on free end of the inner leg of the seal facing outward Sealing lip arranged.

Furthermore, according to a preferred embodiment, the legs of the Seal pressed into corresponding recesses in the metal profiles on the one hand a stable flat contact with the metal profiles and on the other hand to allow easy assembly and disassembly.

The outer leg of the seal is aligned with an outward facing Metal area of the outer metal profile, which is particularly the case with the so-called Mullion-transom construction a good finish on the outside with the Bolts allowed, with only a small area of the seal visible from the outside.

To prevent moisture from penetrating in the area of the upper cross part the outer leg of the seal according to another preferred Embodiment extended towards the window opening and thus assigns one the inner leg of the rubber seal parallel short leg on. Since the seal, as mentioned above, is formed in one piece, wherein when the gasket is made the corners are vulcanized, the short one Leg in the area of the side parts and on the lower cross part by simple Tear removed so that the slats can be opened. In the area of upper cross section is due to the special movement of the pivot point of the slat when opening the slat from the receiving space through the inner Leg and the short parallel outer leg is formed moved out.

In addition, since they do not overlap, the slats point to each other one face seal each facing the front upper and lower lamella surfaces with sealing lip. These seals are advantageously made of rubber or made of a rubber-elastic material and are on the front Glued surfaces to the slats.

According to a further embodiment of the invention, the lamella holders are as Parallelogram gear designed, each parallel in the longitudinal direction inner and outer longitudinal struts of the respective side part exhibit. With these parallel cross struts are movably connected to the the respective side part are movably mounted. Furthermore, that points Parallelogram support struts for each slat on the inner Longitudinal strut and on the side of the slat away from the pivot point of the slat are stored and cause the opening and closing movement of the slat. A Such slat holder is robust, can be extended as desired and provides desired movement of the pivot point of the slats during the opening and Closing movement safely. This parallelogram transmission is driven preferably by means of a cross strut that extends beyond the inner longitudinal strut protrudes and can be driven manually, electrically, pneumatically or hydraulically.

In a further preferred embodiment of the invention, the slats have on the two vertical sides on a metal profile that in the longitudinal direction in Area of the upper end with a recess facing the frame Undercut sits. In this recess is one from the front Fitting plate insertable using a retaining screw on a side Hole is fixed. The fitting plate also has at least one Holding element for holding the slat on the slat holder. This structure of the slats with a metal profile only on the long sides allows one easy manufacture, since these metal profiles are glued together during glass production will. In addition, the weight is reduced, so that the number of Slats in a slat window is essentially not limited. Through the Special design of the side metal profiles is the quick assembly of the individual slats in the already installed frame on the construction site possible because the slats in an inclined position, i.e. H. open position in Moved towards the frame, with the fitting plate in the recess is introduced. The lamella is fixed by turning the retaining screw. In order to is also an easy replacement of a damaged lamella even from the inside. H. possible without setting up a scaffold outdoors.

The holding element on the fitting plate comprises according to an advantageous Embodiment when using the parallelogram transmission a first Retaining pin for fixing to the outer longitudinal strut and one at a distance additional holding pins arranged for fixing to the support strut. The individual struts are of course rotatable about the retaining pin and only in fixed in the axial direction.

Figure 1 shows the visible frame 1 of a louvre window 2 with three louvres 3. In the embodiment, the metal parts are essentially made of Aluminum profile manufactured and the slats contain insulating glass windows 4. The The number of individual slats 3 in the slat window 2 is not based on the Embodiment shown limited number. The insulating glass window is with laterally arranged metal profiles firmly connected, which in turn in a slat bracket, which is arranged in the side parts 9, 10 of the frame 1 is stored. The frame 1 consists of the upper cross part 7, the lower Cross part 8 and the already mentioned side parts 9 and 10. The connection of the Parts with each other are made by invisible connection angles as well as by connecting screws screwed in through the cross parts on the outside. In the figure is also a part of the circumferential rubber seal 6 visible, which is part of the outer metal profile of the upper and lower cross members forming the frame 1 7, 8 and the side parts 9, 10 covers.

This is from the horizontal section shown in FIG. 2 along the line B-B Insulating glass window 4 of a lamella 3 can be seen, the side in metal profiles 5th held and glued to them. The bracket of the metal profiles on the Side parts 9, 10 are not shown in this figure. It only shows in schematic representation of the step-shaped rubber seal 6, the with an inner leg 11 on the inner metal profile 13 and with the outer leg 12 is attached to the outer metal profile 14. The inner Metal profile 13 and the outer metal profile 14 are also over heat-insulating webs 15 connected.

FIG. 3 shows the schematic vertical section along the line A-A from FIG. 1 with closed slats (Figure 3a) and open slats (Figures 3b). Again, the upper and lower cross members 7, 8 are the corresponding Side parts 9, 10 of Figure 2 are formed and together with these form the Frame 1. The same applies to the all-round rubber seal 6 with the inner leg 11 resting on the inner metal profile 13 and the outer metal profile 14 adjacent outer legs 12. The two legs 11, 12 of the rubber seal 6 are connected via the crossbar 16. in the closed state, the inside of the slats 3 lie flat on the edge the outside of the inner leg 11 of the rubber seal 6, as from the Figures 3a and 2 can be seen. There are glued ones between the slats Rubber seals 17, the side surface of the insulating glass window on which the Rubber seal is glued, opposite the other side surface of the Insulated glass window survives. When opening the slats 3, the lever 18 is the Slat holder moved from bottom to top, as shown in Figures 3a and 3b can be seen so that the slats 3 are folded out by the support struts 19 and at the same time the pivot point of the individual slats in relation to the closed one Position moves down and away from the rubber seal 6. The top end 20 of the upper lamella thereby migrates from that of the rubber seal 6 formed space 21 out. The slats 3 of the louvre window thus move when opening away from the window opening 49, so that the additional installation of a fly screen is possible. The room 21 is covered by an additional Extension 22 allows only on the upper cross member 7.

Figure 4 largely corresponds to Figure 3, but here schematically Lamella bracket 23 is shown in the form of a parallelogram gear. How in Figure 3, Figure 4a shows the closed position and Figure 4b the open position. The lamella holder 23 comprises two parallel in the longitudinal direction of the respective Lateral part inner and outer longitudinal struts 24, 25, which over Cross struts 26 to 29 are movably connected. The cross strut 28 is in the Embodiment extended to as a lifting and application point for actuation to serve by hand, hydraulically, pneumatically or electrically. On the inside Longitudinal strut 24 are also movable window support struts 19 stored at the other end spaced from the pivot point 30 of the respective Attack slat 3. The individual struts are connected by pins, whereby, as already mentioned, the slats 3 via the pivot point 30 with the outer Longitudinal strut 25 are connected. The cross struts 26 to 29 are over the Pivot 31 connected to the side part 9. Moved by this articulation the fulcrum 30 of each slat on an arc around the fulcrum 31 what on the one hand, a tight flat contact of the lamella edge on the Rubber seal and on the other hand moving away when opening the Guaranteed rubber seal.

Figure 5 shows a horizontal section of the usual post-rule construction with the side part 9 of the louvre window 2 on one side and one possibly fixed window 32 on the other hand. The side part 9 comprises the inner and outer metal profile 13, 14, the webs 15 and the Rubber seal 6 are connected. The metal profile is a bolt 33 and a screw connection with the post 34 in a known manner connected. Corresponding sealant 35 prevent the ingress of Humidity. The side part 9 shown in FIG. 5 houses the Lamella holder 23, which is explained in more detail below with reference to FIG. 6 becomes.

Figure 6 shows the side part 9 in an enlarged compared to Figure 5 Representation with the insulating glass window 4, which is glued into the metal profile 5. The metal profile 5 has a recess 36 for receiving a fitting plate 37 with the pin 38, via which the lamella 3 on the lamella holder 23 is supported. The formation of the recess 36 and the fitting plate 37 and Pin 38 is explained in more detail below in connection with FIG. 8. To the Pin 38 is the outer longitudinal strut 25 and the elongated cross strut 28 held movably and via a locking washer 39 axially fixed. The cross strut 28 is in turn connected to another pin 40 the inner metal profile 13 of the side part 9 connected. The cross strut 28 is also via the pin 41 with both the inner longitudinal strut 24 and with the support strut 19 rotatably connected, the support strut 19 in this Figure engages behind the pin 38 on the side surface 42 of the slat 3. The Rubber seal 6 is by means of appropriately designed knobs 43, which in suitable recesses 44 in the inner and outer metal profiles 13, 14 intervene, fixed flat against it. The inner leg 11 of the Rubber seal 6 has an additional sealing lip at its free end 45, which prevents the ingress of moisture.

The holes 46 are used to screw in mounting screws and Recess 47 the insertion of mounting brackets when assembling the Frame. Both the pin 38 and the support strut 19 penetrate the Rubber seal 6.

FIG. 7 shows an enlarged cross section through the upper cross member 7, the structure with the exception of the slat bracket 23rd the structure of the side parts 9, 10 and the lower part 8 corresponds. One and only The difference is that the rubber seal 6 in this area Extension 22 has to prevent the ingress of moisture and to form a tight space 21 in the region of the upper end 20 of the lamella.

FIG. 8 shows a section through the edge of a lamella 3 in FIG. 8a the insulating glass window 4 and the glued to the insulating glass window 4 Metal profile 5. As already mentioned, the metal profile 5 has a recess 36 on, which is formed with an undercut, for example also in shape a dovetail, etc., to prevent the fitting plate 37, which is inserted into the metal profile from the end face, in the axial direction of the pin 38 can move. After inserting the fitting plate 37 it is fixed to the metal profile 5 by means of a locking screw 38. Figure 8b shows the inserted fitting plate 37 with the pin 38 and the further pin 41 for holding the support strut 19. In the front view of the Metal profile 5 according to Figure 8c is the arrangement of the locking screw 48 and the pin 38 and 41 can be seen.

Figure 9 shows the upper and lower ends of a slat 3 with the glued Rubber seals 17 in an enlarged view.
