Description

The invention relates to a mounting system of a Venetian blind and a mounting method for this Venetian blind.

Venetian blinds, which are attached to buildings for protection against solar radiation and the associated heat generation or for shading a room, are already known. Furthermore, it is known that these venetian blinds can have a rail system which can prevent a disturbing movement of the Venetian blind due to a draft, if they are attached to the outer wall of a building.

So far, these venetian blinds, hereinafter referred to as Venetian blinds, transported in parts to their destination and assembled there in the course of final assembly at the installation. Only then is a functioning assembly available. This means on the one hand an increased transport costs, and on the other hand, a greater effort in the actual assembly, for example by additionally required tool. If blinds are to be mounted on an exterior wall of a building and not only on the ground floor, for example, a corresponding framework is needed. This also creates additional costs, the assembly on a scaffold is more complex and dangerous and it is therefore desirable to keep the installation time short.

It is therefore an object of the invention to describe a mounting system and an associated assembly method for a Venetian blind with an associated drive device, which allow the most complete assembly of Venetian blind at its production, so that the final installation on an exterior wall of a building or the like can be accomplished as easily and quickly as possible without extensive assembly work. A fast and uncomplicated installation is especially desirable when working at high altitude. As a positive side effect, this should save costs, for example in terms of transport costs.

This object is solved by the features of the independent claims. Advantageous developments of the invention are the subject of the subordinate claims.

The inventor has recognized that it is possible and also particularly advantageous to pre-assemble a Venetian blind as far as possible at its production location, so that the assembly at the actual destination is greatly simplified by a simple plug and rail system.

• zwei Grundschienen, die an einem Befestigungsuntergrund kraftschlüssig und parallel ausgerichtet befestigt sind,
• eine vormontierte Systemeinheit, die auf die Grundschienen aufgesteckt ist, wobei die Systemeinheit aus einer Blende, zwei seitlich angeordneten Steckhaltern, einem Raffstorebehang bestehend aus einer Vielzahl von Lamellen, die an ihren Längsenden Führungsstifte aufweisen, und einem Antriebssystem, aufweisend mindestens ein Getriebe und mindestens zwei Aufwickelvorrichtungen, und
• zwei Behangführungsschienen, in die die Führungsstifte der Lamellen eingreifen können und die an den Grundschienen befestigt sind.

In accordance with this principle, the inventor proposes a mounting system of a venetian blind, which comprises:

• two base rails, which are attached to a mounting base frictionally and in parallel,
• a preassembled system unit, which is attached to the base rails, wherein the system unit of a shutter, two laterally disposed plugs, a Venetian blind consisting of a plurality of fins having guide pins at their longitudinal ends, and a drive system, comprising at least one gear and at least two Winding devices, and
• two drapery guide rails in which the guide pins of the slats can engage and which are fastened to the base rails.

The plug-in holders already attached to the panel during pre-assembly at the production location are used to hold this system unit and its attachment to the base rails, the attachment to the base rails only on site at the actual Assembly is performed. A correspondingly advantageous shape of the plug-in holder provides that the plug-in holder can have a plug-in part, a rail, a middle part and a cover plate. The ideally elongated plug-in part can be inserted into the base rail, wherein the running perpendicular to the male part rail plate allows stable positioning of the plug-in holder in the base rail. In the middle part may be provided a recess in which the gear of an electric motor or a mechanical crank drive the venetian blind can be arranged. The horizontally shaped cover plate can be attached to the panel, for example by screws. Overall, the plug-in holders can thus absorb the entire static load of the external blind and deliver it to the base rails attached to a building.

In principle, the plug-in holder, that is to say the preassembled system unit, can be inserted from the front or from above into the base rail. Depending on the structural conditions, such as a closely spaced roof lintel, it may be advantageous if the base rail is notched at its upper end towards the front, so that plugging the plug-in holder from the front is possible. Of course, if there are no space problems in the final assembly on site, the plug-in holder can of course also be plugged from above onto the base rail, it being advantageous in this case if the base rail is closed to the front. The plug-in holders can then be fixed, for example, by bolts or screws on the base rail and secured against lifting.

To customize the blind at the end of the installation individually to the conditions of the mounting surface and the respective door or window, it may be convenient to provide the plug-in holder with a profile element for height adjustment of the external blind control. In an advantageous variant, the profile element can be designed as a gripper with two oppositely arranged gripping arms. The gripping arms can then include the Raffstorebehang and vary for example by adjusting the mounting height of Raffstorebehanges relative to the panel.

For blinds, which are attached to the outer walls of buildings and their lamellae are therefore exposed in the lowered state, air movements, it is generally useful to fix the lamellae at their longitudinal ends. However, their mobility in the vertical should not be restricted. It may be advantageous if the Behangführungsschienen have a C-shaped cross-section and the guide pins on the slats at their longitudinal ends a thickening. These thickenings at the ends of the guide pins prevent slipping out of the Behangführungsschienen so that the guide pins can not be pulled out by a draft, but still be movable within the rail.

A preferred variant of the invention provides that a plurality of external Venetian blinds can be arranged side by side. For example, this may be the case on a building wall with a window front of many individual windows arranged close to each other. Then, in each case a common base rail in the middle of the two blinds can be used for two juxtaposed shutters, the plug holder can be inserted into the side rails of the two blinds in the one base rail and mirror images of each other.

In another advantageous embodiment of the invention, this blind can additionally have a roller blind for protection against insects, hereinafter called insect roller blind. This insect roller blind can be arranged between the attachment surface, that is to say a house wall, for example, and the external venetian blind, it being sensible to displace the external venetian blind to the full extent in order to completely maintain the function of the venetian blind.

For this purpose, the base rails can be extended outwards to accommodate guide rails for receiving the insect blinds can. In these guide rails can then advantageously the sides of the insect blinds for guidance during winding and unwinding and for stabilization, for example, be positioned in the wind.

This guide makes sense, since the typical materials of the Tuchbehangs of insect blinds are very light and therefore particularly vulnerable to any air movement. In order to achieve a further stabilization of the insect blinds, it is possible to attach at the lower end of the Tuchbehangs advantageously over the entire width of a so-called drop rod. This drop rod can be made for example of aluminum or plastic. Its weight keeps the drapery taut, making it easier to unwind and unwind and makes the drapery less susceptible to air movement.

For winding and unwinding the insect roller blind may preferably have its own drive unit, consisting of either a spring shaft or an electric motor and a cloth shaft, wherein it is convenient to position the drive unit in the fabric shaft in the blind of the venetian blind to space and Save material. In this way, the insect roller blind can be completely covered in the rolled-up state of the panel.

There are several variants for the storage of the fabric shaft. In a variant can be provided on each side of the cloth shaft attached to the plug-in holder, for example screwed or riveted, bearing plate. This variant is particularly well suited for the subsequent attachment of an insect blind to an existing and already mounted external venetian blind. Of course, it can also be used in the pre-assembly of a Venetian blind at the place of manufacture.

Another variant provides that a shaft bearing receptacle is integrated for receiving the roller tube in the plug-in holder. The plug-in holder is thus already made with a shaft mount. This type of attachment is suitable when the venetian blind is mounted together with the insect roller blind.

This assembly process is easy to perform due to the almost complete pre-assembly at the place of manufacture, and allows in a few steps the rapid installation of a blind on a house wall or facade or on a window, the installation of the base rails can be further facilitated by an assembly aid.

This mounting aid can advantageously from a telescopic linkage and left and right respectively a male part, which is modeled on the male part of the plug-in holder and adapted to the dimensions of the base rail exist. The length of the telescopic linkage can be advantageously set and locked to the width of the window or the intended width of the blind to be mounted.

The FIG. 1 shows the rear view of a Venetian blind with mounting system in the assembled state. All hidden components are also shown in their projections. To the right is a complete Venetian blind with two base rails 2 and left a partially shown blind with a base rail 2. Below, only the fully illustrated blind is discussed, the structure and operation of the partially shown blind is analog.

In the upper area is a preassembled system unit consisting of a schematically illustrated Raffstore head strip 3 with a transmission 8, wherein for better clarity, the package of the fins is not shown, a panel 4 and two plug-in connectors 1 mounted on both sides. The drive device includes the gear 8 and in the embodiment shown two winders 8.1 per blind. The entire system unit is inserted with the help of the plug holder 1 in the base rails 2. In this case, the panel 4 and the external blinds header 3 is attached to the gear 8 and the Raffstorebehang to the plugs 1.

The gear 8 of the blind can be driven for example by an electric motor or a mechanical crank drive via a hand crank. It has a drive shaft which is inserted in a continuous over the entire width of the blind hollow shaft 20, wherein the take-up 8.1 are driven via the drive shaft. The gear 8 can be positioned at any position along the hollow shaft 20, even in the area of the take-up 8.1, whose side distances are changed to the base rail accordingly. Accordingly, a crank drive with a hand crank can also be mounted at any position along the hollow shaft 20. The positioning of the transmission 8 or the desired positioning of a hand crank for the crank drive can be selected, for example, taking into account the house facade on which the blind is attached. So that no restrictions arise in the edge regions of the blind, two different versions of the plug-in parts 1 can be used. These variants are used in the description FIG. 5 continue running.

In addition, the drive device may have a mechanical coupling. By this coupling, it is possible with the help of a single gear 8 and a correspondingly extended drive shaft and hollow shaft 20 to operate a plurality of juxtaposed blinds simultaneously. It is possible for many side-mounted blinds also a formation of blinds groups, so for example, two adjacent blinds pairs or threes.

The plug-in holders 1 transfer the entire weight of the external blind control and the panel 4 to the base rails 2, which in turn are mounted on a mounting base, not shown here. Furthermore, located on the upper part of the plug-in holder 1 each have two gripping arms 14, which additionally fix the Venetian blind accessory and on the other via screws 16 allow height adjustment of Raffstorebehanges to achieve optimum adaptation to the particular conditions of the window or door. The exact appearance of the plug 1 is in the FIG. 5 described in detail.

The combination of a plug and rail system described above for the installation of an external Venetian blind allows a simple and quick attachment to a mounting surface. Due to the extensive pre-assembly at the production site, only a few assembly steps have to be carried out at the actual destination: first, two base rails 2 are fixed in a force-fitting manner on a substrate per blind. Thereafter, the preassembled system unit can be inserted with the help of the plug-in holder 1 depending on the structural conditions in the base rails 2 either from the front or from above and secured by screwing, for example against a lifting under load. Subsequently, the Behangführungsschienen - in the FIG. 1 not shown - threaded from below onto the guide pins on both sides of the slats and fixed in a final step to the base rails 2.

The FIG. 2 shows a horizontal section AA through a Venetian blind according to the FIG. 1 at the height of the slats 6. Opposite the FIG. 1 Here are the slats 6 already threaded with their guide pins 7 in the Behängführungsschienen 5 and shown. There are two juxtaposed slats 6 are shown, with one slat 6 is only half visible. The Behangführungsschienen 5 have a C-shaped cross-section. For insertion of the guide pins 7, the Behangführungsschienen 5 are pushed from below onto the guide pins 7. By a thickening at the ends of the guide pins 7 ensures that they can not slip out of the guide rail, but can move freely in the vertical direction, ie when raising and lowering the blind. The Behangführungsschienen 5 are attached to the base rails 2, which in turn are attached to a mounting base 15.

The FIG. 3 shows the top view of a horizontal section through a Venetian blind at the height of the header with the gearbox 8 without external blind with projections of all components. The transmission 8 is designed in this embodiment as a hand cranking gear, the actual Hand crank is not shown. Below the plug-in holder 1 is located on one side of the header with the gear 8 of Raffstorebehanges. By operating the gear 8, the slats can be pulled up and down by an unillustrated elevator belt, which is attached to a also not shown connected to the drive shaft take-up and turning unit and to the lowermost slat, up or is unwound. Both plug-in holder 1 are inserted into the base rails 2. At the base rails, the Behangführungsschienen 5 are also attached and shown. Towards the front, the mechanism of the blind and the disk pack is shielded by the panel 4 against environmental influences.

The FIG. 4 shows a vertical section BB through the venetian blind according to the FIG. 3 with projections of all components. In the middle is the transmission 8 with the winding device 8.1, which is arranged in a recess 13 of the plug-in holder 1. In the center of the transmission 8 is the drive shaft 19, which is inserted in the continuous over the length of the blind hollow shaft 20. The drive shaft drives the take-up device 8.1, so that the lamellae 6 can be left up and down by an elevator belt attached to the lowermost louver. To the external blind, not shown here, which is located in the projection in front of the winding device 8.1, a profile element in the form of two gripping arms 14 arranged on both sides is shown. With the help of adjusting screws not shown in detail on the gripping arms 14, the height of the Raffstorebehangs can be adjusted relative to the aperture 4. The panel 4 is attached to the plugs 1 above the Raffstorebehanges and pulled on one side, that is, the front of the blind down, so that the underlying parts of the blind are shielded from the environment.

In the FIG. 5 is a side view of a plug-in holder 1 shown schematically. The plug-in holder 1 consists of a plug-in part 9, a rail plate 10, a middle part 11 and a cover plate 12. In the middle part 11 is on the one hand a recess 13 in which the transmission of the external blind can be arranged, and on the other hand three pierced spacers 18, by the plug-in holder of two adjacent blinds, if necessary, can be screwed together positively and non-positively. Furthermore, there are two cheeks 21 and 22 at the middle part 11, wherein the cheek 21 is formed on the wall side to the mounting surface and the cheek 22 on the front side to the mounting surface on the central part 11. The wall-side cheek 21 has a recess 23 through which the crank drive can be guided to the transmission.

The Venetian blind can also be adjusted in height relative to the cover plate 12 by means of attached to the cover plate 12 profile elements. The profile elements are not shown in this figure. For attachment of the profile elements, for example by screwing, are located in the cover plate 12 two Behangbefestigungslöcher 17. On the cover plate 12 also not shown here aperture of the blind can be attached. The lower part of the plug-in holder 1 is formed as an elongated plug-in part 9. The plug-in part 9 can be plugged together with the mounted Raffstorebehang and the panel from above or from the front into a non-illustrated base rail, wherein the horizontally formed rail plate 10 is used to stabilize the plug-in holder 1 in the base rail.

In the male part 1, a mirror-image version is possible. Depending on which side of the blind, so left or right, the male part 1 is to be attached, its component can be designed either oriented to the left or right.

As already mentioned, to enable any positioning of the gearbox and the associated crank drive over the entire width of a blind, it is also possible to use an embodiment of the plug-in part 1 in which the vertical middle part 11 is arranged on the opposite side of the cheeks 21 and 22 , Thus, the crank drive or the transmission can also be arranged at a position in which in the embodiment shown here, the middle part 11 is located.

In a further embodiment of the invention, an insect roller blind can additionally be attached for protection against insects. The installation system of Venetian blind according to the FIGS. 1 to 5 remains unchanged.

The FIG. 6 shows the rear view of a venetian blind according to the FIG. 1 , In addition, there is an insect roller blind between the attachment surface not visible here and the external venetian blind. The essential components of this insect blinds are the fabric shaft 25 for winding the Tuchbehangs 27, on each side of a bearing plate 26 which is fixed to the plug holder 1 of the mounting system and serves to receive the fabric shaft 25, and a drop bar stop 28. In this illustration, the Tuchbehang 27th only partially up or unwound from the fabric shaft 25. As a lateral guidance of Tuchbehangs 27 is a guide bar 24 which is fixed to the base rail 2 of the mounting system. Its function corresponds to that of the curtain rail of the Venetian blind, which is not visible here.

At the bottom of Tuchbehangs 27 is a drop bar - not visible here. He complains on the one hand, the relatively light Tuchbehang 27, for example in the wind, and stabilizes it additionally in the guide rail 24 during winding and unwinding. The drop bar stop 28 can be adjusted individually so that the drop bar 30 to the lower edge of the aperture 4 enters and thus is tangible. On the other hand, the fall bar stop 28 prevents the Tuchbehang 27 is wound too far by stopping the drop rod and the lower end of Tuchbehangs 27 winds around the canvas shaft and tangled.

In the FIG. 7 a horizontal section CC is shown by a venetian blind with insect blind. The components of Venetian blinds correspond to the components shown FIG. 2 but without lamellae.

In this illustration, the arrangement of the insect blind is easy to see. The canvas shaft 25 is located approximately at the same height as the drive shaft 19 of the venetian blind and is also covered by the panel 4 to the front. In projection behind the cloth shaft 25 is the plug-in holder 1 with the bearing plate 26. The bearing plate 26 can be preassembled together with the other components of Venetian blind according to the simple mounting system and then plugged into place with the plug holder 1 in the base rail 2. In addition, the guide rail 24 of the insect roller blind and the curtain rail 5 of the external blind, which are fixed to the base rail 2, can still be seen.

In the right part of the drawing, the drop bar stop 28 can be seen. The Tuchbehang 27 has rolled up so far that the drop rod 29 is stopped at its lower end by the drop bar stop 28.

The FIG. 8 shows a horizontal section through a base rail 2 with Behangführungsschiene 5 and guide rail 24. In the FIG. 9 is the one in the FIG. 8 shown section at the level of the slats 6 and Tuchbehangs 27 shown. The base rail 2 is forward - ie away from the mounting surface 15 - extended to provide enough space for the insect roller blind and thus to maintain the function of venetian blind. The guide bar 24 is like the Behangführungsschiene 5 attached to the base rail 2 and stabilizes the Tuchbehang 27 by a lateral guide.

In the FIGS. 10 and 11 In each case, a plug-in holder 1 with a bearing plate 26 and a guide rail 24 is shown. The FIG. 10 shows a vertical section and the FIG. 11 a side view. The bearing plate 26 is located at the central part 11 of the plug-in holder 1 next to the recess 13 for the transmission of the external blind control. It can for example be screwed or riveted. This type of attachment is particularly well suited for retrofitting the insect blinds on the venetian blind.

The FIG. 12 shows the top view of a bearing plate 26. In the middle of the bearing plate 26 is a recess 30 for receiving the fabric shaft. In this variant, the bearing plate can be mounted by means of screws through the mounting holes 31 on the plug-in holder.

The screws 32 for fixing the bearing plate 26 on the plug-in holder are in the FIG. 13 seen in vertical section through the bearing plate.

An alternative attachment of the fabric shaft show the FIGS. 14 and 15 , The FIG. 14 shows a section through a plug-in holder 1 with integrated shaft bearing receptacle 33 and the FIG. 15 a side view of the same. The shaft bearing receptacle 33 or the recess 30 for the cloth shaft bearing is cast directly in the production of the plug-in holder in the middle part 11. This type of attachment is particularly well suited for pre-assembly of the insect blinds and the Venetian blind.

Depending on the structural conditions of the mounting surface of the blind, it is convenient, the plug-in with the preassembled system unit both from above and to be able to plug it into the base rails from the front. In the FIGS. 16 and 17 these possibilities are shown schematically. In each case, a base rail 2 on a mounting surface 15 and a plug-in holder 1. In the FIG. 16 the plug-in holder 1 is inserted from above into the base rail 2. In the FIG. 17 the base rail 2 is notched front at its upper end, so that the plug-in holder 1 can be inserted from the front. The schematic direction of movement is indicated by an arrow. For securing the plug-in holder or the remaining preassembled system unit which is actually located on the plug-in holders - in the FIGS. 16 and 17 not shown for clarity - have these and the base rails 2 holes 38 through which bolts or screws can be performed.

The FIG. 18 shows two mounting aids 34 with two base rails 2. The plug-in parts 35 of the assembly aids 34, which correspond to the plug-in parts of the plug-in holders, have been inserted into the base rails 2. To set the width of the mounting aid 34, this has a telescopic linkage 36, which are fixed with the locking device 37.
