Description

Train carriage for a curtain device

The invention relates to a towing vehicle for a curtain, comprising a rail having a first end and a second end and a fastening means extending between these ends, with which a curtain is detachably fastened to the rail and with glides, with which the rail in a channel of a curtain profile can be slidably stored-

A towing vehicle of this type has become known in the prior art by applicant's CH-A-653 537. This consists of a flat aluminum rail and sliders and drive cams, which are attached to the aluminum rail. The train carriage can be moved horizontally in one channel of a multi-channel curtain profile. On the aluminum rail, a hook tape is attached to the side, on which a curtain can be releasably attached to an upper edge.

Other similar towing cars have become known in the art by DE-A-101 50 777 and US-A-5 109.910. Also known is a train carriage, which is similar to a chain of several links and is provided for a curved curtain profile. However, this carriage is relatively expensive to manufacture and is only suitable for curtain profiles that have a bend with a very large bending radius.

The invention has for its object to provide a train carriage of the type mentioned, which is easier to manufacture and which is also suitable for bends with a relatively small bending radius of, for example, less than 50 cm. The object is achieved in a generic towing car in that the rail is highly flexible, so that it bends elastically when moving in a bend of the curtain profile. It has been shown that such a train car is very smooth and very quiet. It is also surprisingly suitable for bends that have a bending radius of only 10 to 20 cm and a bending angle of 90 °. It is also suitable for curtain profiles with multiple bends, for example for S-shaped curtain profiles. The production is also relatively inexpensive, if the train carriage is comparatively long, for example, has a length of 1 m. The operation is possible as before, for example via a spinning rod.

The train carriage is made in accordance with an embodiment of the invention of flexurally elastic plastic or metal, for example aluminum. The rail is comparatively thin, for example 0.5 mm to 2 mm thick. A particularly suitable plastic, for example, polypropylene, but in principle, other suitable plastics are conceivable.

According to a development of the invention, the rail is made of a laminate and in particular one made of different materials. The films of the laminate may be plastics or metal foils. This allows the production of a comparatively stiff and yet highly flexible with respect to the bending axis Zugwagens.

According to a development of the invention, it is provided that the rail has in an upper region a row of holes for the attachment of glides and / or drivers. The holes of the row of holes are arranged with a comparatively small detent spacing, so that the gliders can be fastened essentially at any point. For attachment, the sliders each have on a support at least one approach, which engages in a hole of the row of holes. It is further provided that a latching tongue is arranged in the carrier, which is locked against the said approach in the same opening. This allows a very simple, yet secure attachment of the slider. The sliders may have rollers in the usual way. Also conceivable are gliders without wheels.

According to a development of the invention it is provided that the train carriage has at least one driver, which has a neck on a holder which in an opening of the ^

Hole row intervenes. These drivers are attached to one end of the rail and allow a packet-wise moving several train cars or curtains.

According to a development of the invention, the rail has a toothing on a lower edge. This serves to fasten the driver and / or the slider. These can be releasably secured to the openings of the row of holes and at this toothing. A particularly secure attachment is possible if the driver has at an upper end a fastening part which can be folded around an upper edge of the rail. This fastening part preferably has at least one latching tongue which can be latched into one of the holes of the row of holes.

According to a development of the invention it is provided that the rail has an upper part which is detachably connected to a lower part. The upper part is connected to sliders and slidably guided with these in a channel of a profile. The lower part serves to attach the curtain, which can be sewn to the lower part, for example.

Preferably, the upper part and the lower part are elongate plate-shaped parts, which are arranged substantially in one plane and which extend over the entire length of the rails. To wash the curtain, the lower part is detached from the upper part. This is particularly simple when, according to a development of the invention, the upper part and the lower part can be released by a displacement in the longitudinal direction of the rail. The upper part and the lower part are each highly flexible.

The train carriage is particularly suitable for a curtain with a multi-channel curtain profile. Such a multi-channel curtain profile has several channels and corresponding more train carriages. For example, such a curtain device 3, 4, 5 or more pull cars have. By moving the carriages around a bend, the curtains can be "parked" outside the window.

Further advantageous features emerge from the dependent claims, the following description and the drawings. Embodiments of the invention will be explained in more detail with reference to the drawing. Show it:

The curtain device 1 shown in Figure 1 has a multi-channel curtain profile 2 shown here only partially, which can be fastened to a building ceiling in front of a window, for example with holders not shown here. The multi-channel curtain profile 2 can be arranged according to Figures 2 and 3 sunk in a niche 10 of a wall 9. However, this is not mandatory. At the multi-channel curtain profile 2 five carriage 5 are mounted, which are guided by sliders 26 each in a channel 13 shown in Figure 2 a profile 12 slidably. 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 carriage 5 is in each case a driver 6, 6 'and 7 (Fig. 11, 12 and 13) attached. This allows a groupwise shifting of the curtains 4. In the figure 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 preferably a mechanical connection and in particular a latching connection. For this O

have the profiles 12 according to Figure 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 comparatively short and arranged on an outer end of a web 14 locking rib 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 outermost left-hand profile can also be designed as a profile 11 according to FIG. This profile 11 differs from the profile 12 by an outer flat surface 30, which forms a termination surface.

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 finally engages behind it. 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 accordingly be connected only on one side, while the profiles 12 can each be connected to a further profile 12 or 11 on both sides.

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 Figure 3. It is also conceivable, however, a multi-channel curtain profile 2 with only two profiles ^

12 or 11 and 12. The multi-channel curtain profile 2 "shown in Figure 7 is made of a profile 11 and four profiles 12.

The multi-channel curtain profile 2 is preferably bent and, for example according to FIG. 8, has 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.

Figure 9 shows a multichannel curtain profile 2 '' which, as can be seen, is bent S-shaped, thus having two bends 2a ¹ "and 2b ^! In addition to the angular configuration shown in Figure 8 and the S-shaped configuration according to Figure 9, other shapes are also possible, for example a U-shaped form, and those with more than two bends are also possible.

8 and 9 are produced by first connecting the profiles 12 or 11 and 12 to a straight multi-channel curtain profile as shown in FIG In this case, the profiles 12 and 11 and 12 are displaced along their longitudinal directions, and then the profiles 12 and 11 and 12 must be shortened accordingly at the ends, so that flat end surfaces 31 and / or 31 'are formed according to Figures 8 and 9. The still open channels 13 are finally closed with the lids 3. Bending becomes transverse to the surface 30 shown in Figure 4 and of course so that the channels 13 are in one plane and are arranged parallel to each other. Thus, the carriages 5 around the bends 2a and 2a, ^m and 2b '' can be moved, these formed highly flexible at least in the longitudinal direction. The carriages 5 each having a flat and elongated bar 23, which for example made of elastically bendable plastic or metal In the bends 2a or 2a '"and 2b'", the traction carriages 5 can bend correspondingly elastically. Since the rails 23 are flexible, they each return to the straight shape shown in FIG 23 are comparatively thin and have, for example, a thickness of 0.5 mm to 2 mm They may be comparatively long and, for example, have a length of 50 to 100 cm The metal is, for example, comparatively thin aluminum sheet. The rails 23 may also be laminates made of the same or different foils, and a laminate of plastic and plastic is also conceivable tallfolien. The height of the rail 23 is for example 3 to 5 cm.

In an upper area 23 rectangular rectangular openings 22 are incorporated in slots having a row of holes for securing the slider 26 and the driver 6, 6 'and 7 shown in Figures 11 to 13. The openings 22 may be rectangular, as shown, but also have a different shape, for example, be round. The slider 26 can be easily placed on the rail 23 and locked. In this case, a projection 2 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. 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 holding part 35 is additionally formed on the holder 27, which is used to fasten the driver 6, 6 'and 7, respectively, can be brought into engagement with a toothing 25 of the base body 23. The toothing 25 is formed in the same pattern as the openings 22. In an upper area, two lugs 37 are formed on the holder 27, each in an opening The holders 27 each have a fastening part 36 which can be bent around a film hinge 34 by 180 ° via these lugs 37. A latching tongue 38 which is only partially visible in FIGS. 11 to 13 is formed on the fastening part 36; 36 engages in one of the openings 22. The drivers 6, 6 ' ^

or 7 can thus be very easily and yet securely and releasably attached to the carriage 5.

The rail 23 is arranged laterally a fastening part 24 for releasably securing the curtains 4. This fastening part 24 extends over the entire length of the rail 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. The fastening part 24 could alternatively but also be integrally formed in the rail 23. Of course, other connections are also possible here.

FIG. 15 shows a curtain device 1, which has pull carriages 5 ', which are each designed according to FIG. These train carriages 5 'have a rail 23' to which a plurality of sliders 26 'are releasably secured. The rail 23 'is also highly flexible and consists of an upper part 39 and a lower part 40. The upper part 39 serves to guide the towing vehicle 5' in the multi-channel curtain profile 2 'according to FIG 21. The multi-channel curtain profile can also be formed as described above be. The lower part 40 serves for fastening a curtain 4. The curtain 4 may be sewn to the lower part 40, for example.

The upper part 31 and the lower part 40 are completely separable from each other. For this purpose, these two parts are slidably connected. The connection has a web 44 on the upper part 39 and a web 45 on the lower part 40. The two webs 40 and 45 each engage in a groove 47 and 46 of the other part. The lower part 40 can be removed from the upper part 39 by being displaced in the longitudinal direction of the rail 5 '. Accordingly, the lower part 40 with the example sewn curtain 4 can be attached to the upper part 39 again. Instead of said sliding connection but other detachable connections are conceivable. It is essential that the upper part 39 and the lower part 40 are arranged in a common vertical plane. The weight of the curtain 4 generated in this case on the carriage 5 'no torque.

For attachment of the slider 26 'and the follower 53 and 55 shown in Figures 19 and 20, the upper part 39 has at regular intervals teeth 43, each having a hole 41. Recesses 42 are provided between the teeth 43. The holes 41 form a row of holes and the teeth 43 a row of teeth. The sliders 26 'are each attached to two adjacent teeth 43. In the attached state, a tooth 43 in each case engages between two webs 48 and 50. These webs 49 and 50 are elastically deflectable. A cam 49, which is integrally formed on the web 48 on the other side, engages in a hole 41 of the corresponding tooth 43. The axis 58 of the corresponding roller 48 is in this case in a gap 42. The teeth 43 and the holes 41 are also used for fastening the drivers 53 and 55. The driver 53 has two cams 54, which are each inserted in a hole 41 and in particular latched. The driver 55 has a cam 56 which is inserted or latched into a hole 41. This allows a simple and secure attachment of the drivers 53 and 55 on the upper part 39.

The multi-channel curtain profile 2 'shown in Figure 21 differs from the multi-channel curtain profile 2 in particular by the formation of end profiles 51. These each have an outer side wall 52, which allow a particularly suitable conclusion. This especially in aesthetic terms.

Figures 22 to 24 show sliders 59, 60 and 61, to each of which a driver 62, 63 and 64 is attached. These drivers 62, 63 and 64 are thus not directly to the rail 23 or 23 ', but on the slider 59, 60 and 61 attached. In the case of the slider 60 according to FIG. 23, the carrier 63 is pushed onto a holder 65 and latched onto one of a plurality of depressions 23. When slider 61, the driver 64 is pushed onto a holder 66 and latched by a latching tongue 67 at this.
