The invention relates to a multichannel curtain profile for a curtain device, having a plurality of downwardly open guide channels for mounting respectively at least one carriage.
A multichannel curtain profile and a curtain device having such a multichannel curtain profile have been disclosed in the prior art by CH-A-653 537 of the applicant. The multichannel curtain profile disclosed there is provided for a three-tracked flat curtain device. Three carriages, which can be moved in the rail by means of a hand draw system, are mounted on the multichannel curtain profile. The carriages are provided with stops and driver cams and respectively with a flat aluminum rail. A barbed Velcro tape, to which a curtain tape can be detachably fixed by means of a barbed Velcro tape, is fixed on the multichannel curtain profile.
Further multichannel curtain profiles and flat curtain devices are disclosed in U.S. Pat. No. 5,109,910 and DE 101 50 777 A. Such multichannel curtain profiles are generally mounted in front of a window and enable lateral displacement of curtain panels. It is frequently desired for the panels to be able to be displaced completely out of the region of the window, in order for it to be possible to look through the entire window. In the case of very wide panels, this requires a correspondingly large free space next to the window. This is also referred to as “parking” the panels. An angular profile can be used to deflect the panels, for example through 90°, next to the window and thus arrange them in front of a wall which runs at right angles to the window. Hitherto it was, however, very complicated and difficult to produce multichannel curtain profiles which are bent through a comparatively narrow radius.
The object of the invention is to provide a multichannel curtain profile which can be bent through a comparatively small radius of, for example, 90°.
The multichannel curtain profile according to the invention is characterized in that it is produced from a plurality of profiles which respectively form one of the guide channels and which can be displaced in the longitudinal direction of the channels and are fixedly connected to each other transversely to the longitudinal direction. Surprisingly, it has been shown that such a multichannel curtain profile having a comparatively small bending radius of, for example, 10 to 20 cm can be bent through an angle of 90°. In addition, the multichannel curtain profile can be bent repeatedly, for example in an S shape. The individual profiles connected to each other are comparatively narrow and can be displaced relative to each other during bending. As a result of the fixed connection transversely to the longitudinal direction, the profiles remain, however, fixedly connected to each other during and after bending. The multichannel curtain profile thus forms a unit which can be mounted like simpler profiles. Multichannel curtain profiles having, for example, up to five or more channels are possible. Five-tracked curtain devices bent for example in an S shape can thus be produced with the multichannel curtain profile. Since bending through, for example, 90° with a comparatively small radius is possible, it is also possible to park the panels or curtains on a side wall in comparatively small spaces. The multichannel curtain profile according to the invention is suitable in particular for a flat curtain device and in particular a curtain device having horizontally displaceable panels. It is, however, also possible to produce other curtain devices, for example gathered curtain devices.
According to one refinement of the invention, the profiles are respectively mechanically coupled to each other essentially over their entire length. The multichannel curtain profile can be produced in a particularly simple manner when, according to one refinement of the invention, the profiles are respectively essentially non-detachably latch-locked with each other. Alternatively, a dovetail connection is also possible. Such latch locking or dovetail connections can be produced very simply and safely, wherein the profile can be displaced in the longitudinal direction. Such profiles can be produced in particular as aluminum profiles.
The invention also relates to a curtain device having at least one multichannel curtain profile. This curtain device has a plurality of carriages, to which a curtain can respectively be fixed and which are respectively guided displaceably in one of said channels. The carriages can, for example, be moved by means of a hand draw system. Other drives, and in particular also a motorized drive, are, however, also conceivable.
The invention also relates to a method for producing a multichannel curtain profile. In this method, a plurality of profiles are connected to each other displaceably in the longitudinal direction along at least one longitudinal side and these profiles connected to each other are bent together transversely to their longitudinal extent.
Further advantageous features emerge from the dependent patent claims, the following description and the drawing.
An illustrative embodiment of the invention is explained in greater detail below with reference to the drawing, wherein:
The curtain device 1 shown in
As already mentioned, the multichannel curtain profile consists of a plurality of profiles 12, which respectively possess a channel 13 extending in the longitudinal direction of the profiles 12. The channels 13 are respectively open at the bottom along a slot 15. In this slot 15, the slides 26 are guided. The profiles 12 are, in particular, aluminum profiles, which can be powder-coated or anodized. The profiles 12 can also, however, be made of another suitable bendable material. The profiles 12 are respectively fixedly connected to each other at the side and along their entire length. The connection between in each case two profiles 12 is preferably a mechanical connection and, in particular, a latching connection. For this purpose, the profiles 12 according to
The multichannel curtain profile 2 according to
The multichannel curtain profile 2 consists of five profiles 12 and is thus five-tracked. The number of profiles 12 which are connected to one another is optional per se. For example, a multichannel curtain profile 2′ having eight profiles 12, as is shown in
The multichannel curtain profile 2 is preferably curved and possesses, for example, according to
The curved multichannel curtain profiles 2 and 2′″ according to
To enable the carriages 5 to be moved around the bends 2a or 2a′″ and 2b′″, these are highly flexible in configuration, at least in the longitudinal direction. The carriages 5 possess a flat and elongated basic element 23, which is made, for example, of a flat and comparatively thin plastic rail. In the bends 2a or 2a′″ and 2b′″, the carriages 5 can bend with corresponding elasticity. Since the carriages 5 are flexible, they respectively pass back into the straight form shown in
In an upper region, rectangular or round openings 22 are incorporated in the element 23, which openings have a row of holes for fixing of the slides 26 and of the drivers 6, 6′ and 7 shown in
A fixing part 24 for the detachable fixing of the curtains 4 is arranged on the side of the element 23. This fixing part 24 extends over the entire length of the element 23 or of the carriage 5. The fixing part 24 is, for example, a barbed Velcro tape, which can be detachably connected to a smooth Velcro tape of the corresponding curtain 4. However, other connections are here, of course, also conceivable. The fixing part 24 may, however, also be integrally incorporated in the element 23.
