The invention relates to a carriage for a curtain device, comprising a rail which has a first end and a second end and a fixing means extending between these ends, which fixing means is used to detachably fix a curtain to the rail, and comprising slides with which the rail can be displaceably mounted in a channel of a curtain profile.
A carriage of this type has been disclosed in the prior art in CH-A-653 537 of the Applicant. This consists of a flat aluminum rail and slides, as well as driver cams fixed to the aluminum rail. The carriage is horizontally movable in a channel of a multichannel curtain profile. Attached to the side of the aluminum rail is a hook tape, to which a curtain, by an upper border, can be detachably fixed.
Further similar carriages have been disclosed in the prior art in DE-A-101 50 777 and U.S. Pat. No. 5,109,910. A carriage which consists of a plurality of links and is intended for a curved curtain profile is also known. However, this carriage is comparatively complex in its production and is suitable just for curtain profiles which have a bend with very large bending radius.
The object of the invention is to provide a carriage of said type which is easier to produce and which is also suitable for bends with comparatively small bending radius of, for example, less than 50 cm.
In a carriage of the generic type, the object is achieved by virtue of the fact that the rail is of highly flexible configuration, so that it bends with corresponding elasticity when the carriage is displaced in a bend of the curtain profile. It has been shown that such a carriage runs very smoothly and is also very quiet. Surprisingly, it is also suitable for bends which have a bending radius of just 10 to 20 cm and a bending angle of 90°. Moreover, it is also suitable for curtain profiles having a plurality of bends, for example for S-shaped curtain profiles. The production is comparatively cost-effective even when the carriage is comparatively long, for example is 1 m in length. As previously, actuation is possible, for example, by means of a draw rod.
According to one refinement of the invention, the carriage is made of flexurally elastic plastic or metal, for example aluminum. The rail is comparatively thin, for example 0.5 to 2 mm thick. A particularly suitable plastic is, for example, polypropylene, though other suitable plastics are also in principle conceivable.
According to one refinement of the invention, the rail is made of a laminate and, in particular, of a laminate of different materials. The sheets of the laminate can be plastics or, indeed, metal foils. This allows the production of a comparatively rigid and yet, with respect to the bending axis, highly flexible carriage.
According to one refinement of the invention, it is provided that the rail has in an upper region a row of holes for the fixing of slides and/or drivers. The holes of the row of holes are arranged with a comparatively small latch spacing, so that the slides can be fixed essentially at any chosen spot. For fixing, the slides respectively have on a support at least one protrusion, which engages in a hole of the row of holes. It is further provided that in the support there is arranged a latching tongue, which opposite said protrusion is latched into the same opening. This allows a very simple and yet secure fixing of the slides. The slides can have rollers in the usual way. Slides without rollers are also conceivable, however.
According to one refinement of the invention, it is provided that the carriage has at least one driver, which possesses on a bracket a protrusion, which engages in an opening in the row of holes. These drivers are fixed to one end of the rail and allow a plurality of carriages or curtains to be displaced together in packs.
According to one refinement of the invention, the rail has on a lower margin a tooth system. This serves for the fixing of the drivers and/or slides. These can be correspondingly fixed to the openings in the row of holes and to this tooth system. A particularly secure fixing is possible when the driver has at an upper end a fixing part, which can be placed around an upper edge of the rail. This fixing part preferably has at least one latching tongue, which can be latched into one of said holes of the row of holes.
According to one refinement of the invention, it is provided that the rail has a top part which is detachably connected to a bottom part. The top part is connected to slides and is displaceably guided with these in a channel of a profile. The bottom part serves for the fixing of the curtain, which can be sewn, for example, to the bottom part.
Preferably, the top part and the bottom part are elongated, plate-like parts, which are arranged essentially in one plane and which extend over the entire length of the rails. For washing of the curtain, the bottom part is detached from the top part. This is particularly simple when, according to one refinement of the invention, the top part and the bottom part can be released by a displacement in the longitudinal direction of the rail. The top part and the bottom part are respectively highly flexible.
The carriage is suitable, in particular, for a curtain device having a multichannel curtain profile. Such a multichannel curtain profile possesses a plurality of channels and a corresponding number of carriages. For example, such a curtain device can have 3, 4, 5 or even more carriages. Through displacement of the carriages around a bend, the curtains can be “parked” outside the window.
Further advantageous features emerge from the dependent patent claims, the following description and the drawing.
Illustrative embodiments of the invention are explained in greater detail below with reference to the drawing, wherein:
The curtain device 1 shown in
As already mentioned, the multichannel curtain profile 2 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 respectively possess a flat and elongated rail 23, which is made, for example, of elastically bendable plastic or metal. In the bends 2a or 2a′″ and 2b′″, the carriages 5 can bend with corresponding elasticity. Since the rails 23 are flexible, they respectively pass after a bend back into the straight form shown in
In an upper region, rectangular through openings 22 are incorporated in slots 23, which openings have a row of holes for fixing of the slides 26 and of the drivers 6, 6′ and 7 shown in
The rail 23 is arranged on the side of a fixing part 24 for the detachable fixing of the curtains 4. This fixing part 24 extends over the entire length of the rail 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. The fixing part 24 could alternatively, however, also be integrally incorporated in the rail 23. However, other connections are here, of course, also conceivable.
The top part 31 and the bottom part 40 are fully separable from each other. To this end, these two parts are displaceably connected to each other. The connection possesses a web 44 on the top part 39 and a web 45 on the bottom part 40. The two webs 40 and 45 respectively engage in a groove 47 and 46 of the other part. The bottom part 40 can be removed from the top part 39 by displacement in the longitudinal direction of the rail 5′. Correspondingly, the bottom part 40 with the, for example, sewn-on curtain 4 can be fixed again to the top part 39. In place of said displaceable connection, other detachable connections are also, however, conceivable. The essential point is that the top part 39 and the bottom part 40 are arranged in a common vertical plane. In this case, the weight of the curtain 4 generates no torque upon the carriage 5′.
