Description

The invention relates to a multi-channel curtain profile for a curtain device with a plurality of open-bottom guide channels for storage of at least one train carriage.
A multi-channel curtain profile and a curtain with such a multi-channel curtain profile are known in the art from the CH-A-653 537 have become known to the applicant. The multi-channel curtain profile disclosed herein is intended for a three-panel panel curtain. On the multi-channel curtain profile three train carriages are mounted, which are movable by means of a Schleuderzugs in the rail. The train carriages are equipped with stops and drive cams and each with a flat aluminum rail. At the multi-channel curtain profile is a barb band
attached to which a curtain tape can be releasably secured by means of a barb tape.
Further multi-channel curtain profiles and panel curtain units are available from US 5,109,910 and the DE 101 50 777 A known. Such multi-channel curtain profiles are usually mounted in front of a window and allow lateral displacement of curtain panels. Often it is desirable that the panels can be moved completely out of the area of the window so that full view through the window is possible. For very wide panels, a correspondingly large space next to the window is required. It is also known as a "parking" of the panels.Angled profile allows the panels adjacent to the window to be deflected 90 °, for example, in front of a wall that is perpendicular to the window, but so far it has been very complicated and difficult To produce multi-channel curtain profiles that are bent to a comparatively narrow radius.

Out DE 1 838 354 U is a curved, multi-track rail system known, wherein a piece of elbow on individual rails, connected to a connector is formed. In this case, the individual rails and the connecting pieces by means of lugs and grooves, formed on the adjacent surfaces, are pushed together on their entire length. A disadvantage proves that the elbow is fixed and therefore such a track system can not be brought into any curved shape.
The invention has for its object to provide a multi-channel curtain profile which is bendable by a relatively small radius of for example 90 °.

The multi-channel curtain profile according to the invention with straight and curved regions is made from a plurality of profiles which each form one of the guide channels. The multi-channel curtain profile is characterized in that the profiles in the longitudinal direction of the channels are displaceable and at least transversely to the longitudinal direction firmly connected to each other by a latching connection. It has surprisingly been found that such a multi-channel curtain profile can be bent by an angle of 90 ° with a comparatively small bending radius of for example 10 to 20 cm. In addition, the multi-channel curtain profile can also be bent several times, for example S-shaped. The individual interconnected profiles are relatively narrow and can move relative to each other when bending. Due to the fixed connection transversely to the longitudinal direction, however, the profiles remain firmly joined together during bending as well as afterwards. The multi-channel curtain profile thus forms a unit that can be mounted like simpler profiles. There are multi-channel curtain profiles, for example, with up to five or more channels possible. The multi-channel curtain profile can thus be used to produce, for example, S-shaped curved five-level curtain devices. Since a bend of 90 °, for example, with a relatively small radius is possible, it is possible to park the panels or curtains on a side wall even in comparatively small rooms. The inventive multi-channel curtain profile is particularly suitable for a flat curtain device and in particular a curtain device with horizontally movable panels. But it is also possible to produce other curtains, such as Raffvorhang facilities.

According to a development of the invention, it is provided that the profiles are each mechanically coupled to one another essentially over their entire length. A particularly simple production of the multi-channel curtain profile results when, according to a development of the invention, the profiles are in each case latched substantially inseparably with one another. Alternatively, a dovetail connection is possible. Such locks can be made very easily and safely, the displacement in the longitudinal direction of the profile is possible. Such profiles can be produced in particular as aluminum profiles.

The invention also relates to a curtain device with at least one multi-channel curtain profile. This curtain device has a plurality of train carriages, to each of which a curtain can be fastened and which are displaceably guided in each case in one of said channels. The train carriage can be moved, for example by means of a Schleuderzugs. But there are also other drives and in particular a motor drive conceivable.

The invention also contemplates a method of making a multi-channel curtain profile. In this method, it is provided that a plurality of profiles along at least one longitudinal side in the longitudinal direction are displaceably connected to each other and that these interconnected profiles are bent together transversely to their longitudinal extent.

In the FIG. 1 shown curtain means 1 has a here only partially shown multi-channel curtain profile 2, which is fastened to a building ceiling in front of a window, for example with holders not shown here. The multi-channel curtain profile 2 can according to the FIGS. 2 and 3 be recessed in a niche 10 of a wall 9. However, this is not mandatory. On multi-channel curtain profile 2 five train carriage 5 are mounted, each with sliders 26 in an in FIG. 2 shown channel 13 of a profile 12 are guided displaceably. At each carriage 5, a curtain 4 is releasably secured, which is relatively wide and extends vertically. The channels 13 are closed at the ends in each case with a latched lid 3. At the ends of the train carriage 5 is a respective driver 6, 6 'and 7 ( Fig. 11, 12th and 13 ) attached. This allows groupwise moving the curtains 4. In the FIG. 1 the front curtain 4 is omitted for illustrative reasons. The curtains 4 can be different. They can be designed, for example, as flat curtains or as Roman blinds.
The multi-channel curtain profile 2 consists, as already mentioned, of a plurality of profiles 12, each of which has a channel 13 which extends in the longitudinal direction of the profiles 12. The channels 13 are each open at the bottom along a slot 15. In this slot 15, the slider 26 are guided. The profiles 12 are in particular aluminum profiles, which may be powder-coated or anodized. However, the profiles 12 may also be made of another suitable bendable material. The profiles 12 are each connected laterally and firmly along their entire length. The connection between each two profiles 12 is a latching connection. For this purpose, the profiles 12 according to FIG. 5 on the left side over the entire length of the profile 12 extending laterally projecting locking rib 17 and in a lower region a likewise extending in the entire length of the gripping member 19 which is hook-shaped in section. On the right side, the profiles 12 each have in the upper region a downwardly extending relatively short and arranged on an outer end of a web 14 locking lip 16 and in the lower region a receptacle 18, which also extends over the entire length of the profile 12. The multi-channel curtain profile 2 according to FIG. 2 consists of five identical profiles 12. However, the extreme left profile can also according to the FIG. 4 be formed as a profile 11. This profile 11 differs from the profile 12 by an outer flat surface 30, which forms a termination surface.

The FIG. 6 shows how a profile 11 is mechanically connected to a profile 12. First, the gripping member 19 is inserted into the receptacle 18. In the direction of the arrow 20, the profile 12 is now pivoted against the profile 11, so that the locking rib 17 slides along the locking rib 16 and this finally grasped behind. The two profiles 11 and 12 are now firmly connected along their entire length. At the same time, the profiles 11 and 12 can be displaced in the longitudinal direction against each other. The profiles 11 and 12 can thus slide relative to each other in the longitudinal directions. However, they are firmly connected to one another transversely to the longitudinal direction. Instead of the locking connection shown, another connection is possible, for example, a dovetail connection. This also allows a longitudinal displacement with simultaneous anchoring transverse to the longitudinal direction. The connection between two profiles 12 is the same. The assembly also takes place according to FIG. 6 , The profile 11 can be connected according to only one side, while the profiles 12 can be connected in each case on both sides with a further profile 12 and 11 respectively.

The multi-channel curtain profile 2 consists of five profiles 12 and is thus five-level. The number of profiles 12 that are connected to each other is arbitrary. It is also conceivable, for example, a multi-channel curtain profile 2 'with eight profiles 12, as shown in FIG. 3 is shown. It is also conceivable, however, a multi-channel curtain profile 2 with only two profiles 12 and 11 and 12. The in FIG. 7 shown multi-channel curtain profile 2 "is made of a profile 11 and four profiles 12.

The multi-channel curtain profile 2 is preferably bent and has for example according to FIG. 8 a bend 2a and a straight arm 2b and a second straight arm 2c. The bend 2a is for example a bend by 90 ° or less than 90 ° and a bending radius of preferably less than 50 cm, in particular 10 to 20 cm. The longer arm 2c is in particular the arm which extends horizontally over a window. The shorter arm 2b extends laterally adjacent to the window at right angles therefrom. The length of the arm 2b corresponds approximately to the width of a curtain 4 or the length of a towing vehicle 5. The train carriages 5 can each be moved along the multi-channel curtain profile 2 between the two arms 2b and 2c. If the train carriages 5 or the curtains 4 are located in the region of the arm 2c, they are located in front of the window, not shown here. If the train carriage 5 and the curtains 4, however, moved into the arm 2b, they give the window free. Of course, it is also possible for part of the towing carriages 5 to be located in the region of the arm 2c and for the other towing carriages 5 to be in the region of the arm 2b or 2a.

The FIG. 9 shows a multi-channel curtain profile 2 "', which is bent as shown S-shaped, thus having two bends 2a'" and 2b "' FIG. 8 and the S-shaped training according to FIG. 9 Other shapes are possible, for example, a U-shaped form. There are also possible with more than two bends.

The curved multi-channel curtain profiles 2 and 2 "'according to the FIGS. 8 and 9 are prepared by first the profiles 12 and 11 and 12 according to FIG. 6 be connected to a straight multi-channel curtain profile. Subsequently, this straight multi-channel curtain profile is bent in a bending device on a corresponding die in the desired shape. Here, the profiles 12 and 11 and 12 shift along their longitudinal directions. At the ends then the profiles 12 and 11 and 12 must be shortened accordingly, so that flat end faces 31 and 31 'according to the FIGS. 8 and 9 be formed. The still open channels 13 are finally closed with the lids 3.

So that the carriages 5 can be moved around the bends 2a and 2a '' and 2b '', they are designed to be highly flexible at least in the longitudinal direction. The carriage 5 have a flat and elongated body 23, which is made for example of a flat and relatively thin plastic rail. In the bends 2a and 2a "'and 2b"', the Turn the carriage 5 accordingly elastically. Since the train carriages 5 are flexible, they each go back to the in FIG. 10 shown straight form over.

In an upper area in the body 23 through rectangular or round openings 22 are incorporated, which has a row of holes for attaching the slider 26 as well as in the FIGS. 11 to 13 shown driver 6, 6 'and 7, respectively. The slider 26 can be easily placed on the base body 23 and locked. In this case, a projection 32 of a carrier 29 engages in one of the openings 22. In the same opening engages a latching tongue 33 from the other side. The slider 26 is thus releasably connected to the train carriage 5 in the intended position. On the slider 26 rollers 28 may be stored, which allow a very low-friction movement of the carriage 5. Gliders without rollers 28 are also possible, however, and the drivers 6, 6 'and 7 respectively have laterally projecting wings 8, 8' and 8 ", which are formed on a holder 27. In a lower region, a holder 27 is also provided Holding part 35 is formed, which can be brought into engagement with a toothing 25 of the base body 23 for fastening the driver 6, 6 'or 7. The toothing 25 is formed in the same grid as the openings 22. In an upper area are on the holder 27 two Lugs 37 are formed, which are each insertable into an opening 22. About these lugs 37, the holders 27 each have a fastening part 36 which is umbiegbar by a film hinge 34 by 180 ° FIGS. 11 to 13 only partially visible latching tongues 38 integrally formed, which engages in one of the openings 22 with bent fastening part 36. The drivers 6, 6 'and 7 can thus be very easily and yet securely and releasably secured to the carriage 5.

On the body 23, a fastening part 24 for releasably securing the curtains 4 is arranged laterally. This fastening part 24 extends over the entire length of the body 23 or of the towing vehicle 5. The fastening part 24 is, for example, a barb band, which can be detachably connected to a hook-and-loop tape of the corresponding curtain 4, not shown here. It is here but of course other connections are possible. The attachment member 24 may also be integrally machined in the body 23. <B> LIST OF REFERENCES </ b> 1 curtain device 18 recording 2 multi-channel curtain profile 19 gripping part 2a bend 20 arrow 2b arm 22 openings 2c arm 23 bodies 3 lids 24 fastening part 4 curtain 25 teeth 5 train cars 26 gliders 6 drivers 27 holders 7 drivers 28 rolls 8 wings 29 carriers 9 wall 30 area 10 niche 31 front side 11 profile 32 approach 12 profile 33 latching tongue 13 channel 34 film hinge 14 footbridge 35 holding part 15 slot 36 fixing part 16 locking rib 37 approach 17 Rastrip 38 latching tongue
