Description

Description

The present invention relates to a rail assembly for at least one curtain and/or at least one curtain, the rail assembly having at least two rail sections which meet in a corner of the rail assembly at a right angle or an obtuse angle. In addition, the invention also relates to a slider body for the slidable mounting of at least one curtain or at least one sheer curtain in a rail arrangement.

In rail assemblies in which two rail sections form a corner and are arranged at a right or obtuse angle relative to each other, it is usually difficult to move the curtain or curtain suspended on slider bodies in the rail assembly to lead the corner.

In the prior art, there are numerous solutions in which the rail assembly has a rounded transition of whatever kind instead of a corner. In the prior art, however, this does not form a corner, which often entails disadvantages in terms of optics. Examples of non-genus rail arrangements with rounded transitions instead of corners can be found, for example, in CN 202355153 U or also in CN 210276818 U.

The object of the invention is to improve a rail arrangement of the above type, in which the rail sections are arranged at a right or obtuse angle and thus actually form a corner, in that the curtains and/or curtains hanging on the slider bodies can be guided better around the corner.

In a rail arrangement according to the invention, it is provided for this purpose that a guide body is arranged or formed within the rail sections meeting in the corner, the guide body having at least one rounded deflection surface for deflecting guided in the rail arrangement and attached to the curtain or curtain or attachable slider bodies from one of the rail sections across the corner into the other of the rail sections.

A basic idea of the invention is therefore to allow the rail sections to actually meet in a corner at a right angle or an obtuse angle, but to provide a guide body within the rail sections in the area of the corner, which guides the slider bodies on which the curtain or the curtain hangs or is attached, leads along a rounded deflection surface from one of the rail sections over the corner into the other of the rail sections. Of course, what is meant here is that the slider bodies can be moved in one direction as well as in the other direction over the corner into the respective rail sections.

The invention has the advantage that, viewed optically from the outside, a corner in the form of a right angle or an obtuse angle is actually formed in the rail arrangement, but within the rail sections that meet the guide body ensures that the slider bodies can be easily moved with relatively little resistance can be pushed or pulled from one rail section over the corner into the other rail section. In this way, corners with a right angle, ie a 90° angle, but also corners with an obtuse angle, ie an angle greater than 90° and less than 180°, can be realized. The obtuse angles are preferably angles between 90° and 175°. Particularly preferred obtuse angles are 135°, 157.5° and 175°.

A corner in the sense of the invention is therefore not a rounded area but a corner formed at a right angle or an obtuse angle.

The guide body can be designed in one piece or in several parts. The guide body can be integrated into the rail sections of the rail arrangement. However, the guide body can also be an initially separate part, which is then connected to the rail sections of the rail arrangement in order to form the corner in this way. Is particularly preferred

provided that the guide body is a plug-in part for plugging into the rail sections. The plug-in part and the rail sections are advantageously designed in such a way that the rail sections can be connected to one another in a form-fitting manner without play by means of the guide body.

[0010] Rail arrangements according to the invention can be single-bar but also multi-bar. In this case, single-track means that the rail arrangement has only one running channel, in which only one curtain or only one sheer curtain with corresponding slider bodies can be guided. In the case of multi-track rail arrangements according to the invention, several curtains and/or drapes can be guided on corresponding slider bodies in two or more running channels of the rail arrangement, which are generally parallel to one another, as is known per se.

The guide body can be made of plastic such as POM (polyoxymethylene) or PETG (polyethylene terephthalate modified with glycol) or of metal or of wood or of a composite material. It can, for example, be produced by injection molding, but also, for example, by 3D printing in the case of custom-made products. The same materials and manufacturing methods can also be used for the sliders.

The rail sections, which in principle could also be referred to as rails, are preferably made of metal, optionally coated, e.g. as an extruded profile. However, the rail sections or rails can also be made of plastic, wood or composite material.

The rail sections of the rail arrangement according to the invention are preferably not bent. Rather, in order to form the corner, it is preferably provided that the rail sections each have mitred ends and are joined together with their mitred ends to form the corner. The miter angles suitably correspond to half the angle at which the corner is formed. If the corner of the rail arrangement is a right angle, then the miter angles are conveniently 45°. The same preferably applies to obtuse angles.

In preferred embodiments, the guide body has two freely projecting guide body legs, each of the guide body legs being insertable or already inserted into one of the rail sections. As already mentioned, plugging the guide body and rail sections together advantageously results in a play-free, form-fitting connection between the rail sections brought together at the corner.

The guide body advantageously has two guide channels leading to the rounded deflection surface. In these guide channels, the slider bodies can be guided towards and away from the deflection surface, which is designed to be rounded. One or at least one of the guide channels is favorably located in each guide body leg.

In particularly preferred embodiments, it is provided that the opening widths of the guide channels decrease in the direction towards the rounded deflection surface. This leads to particularly good guidance of the slider bodies in the guide channels of the guide body, both when they are moved in the direction of the rounded deflection surface and away from it.

Preferred variants of the invention provide that the guide channels are each delimited by an outer channel delimiting wall and each by an inner channel delimiting wall opposite the respective outer channel delimiting wall, with the rounded deflection surface forming a transition between the outer channel delimiting walls and on the inner channel boundary walls guide ramps are formed, which meet in one of the rounded extending deflection surfaces opposite, inner apex area of the guide body and whose ramp width increases towards the inner apex area. The slider bodies are guided particularly well by these guide ramps in the direction of the rounded deflection surface.

The inner apex area is preferably also rounded. The radius of curvature of the inner apex area is advantageously smaller than the radius of curvature of the rounded deflection surface.

In addition to the rail assembly itself, the invention also relates to a slider body for slidably storing at least one curtain or at least one sheer curtain in a rail assembly. This rail arrangement can preferably be designed according to the invention. The slider body has a slider head, a slider neck and a slider base, the slider head being connected to the slider base by means of the slider neck and at least one fastening device for fastening the curtain to the slider body being formed on the slider base. The fastening devices can be designed in the form of hooks, eyes and the like, as is known per se. In the case of slider bodies according to the invention, it is now provided that the slider head is delimited on two opposite sides by rounded, preferably partially elliptical, outer sides and on two other opposite sides by flat outer sides. This special shape of the slider head has the advantage that the rounded outer sides can slide particularly well along the rounded deflection surface in order to support the deflection of the slider body in the area of the corner. Due to the flat outer sides formed on opposite sides, the sliding bodies lined up one behind the other lie particularly well against one another, so that they guide one another. In particular, this means that the curtain or drape with the slider bodies attached to it can not only be pulled from one of the rail sections over the corner into the other rail section, but can also be pushed particularly well.

In the sense of a simple pulling and pushing, particularly preferred variants provide that the slider head and/or the slider base, preferably in each case, are designed to be bevelled towards the slider neck.

This type of slider body works particularly well together with rail assemblies according to the invention. Preferred embodiments of the rail arrangement according to the invention therefore provide that a large number of slider bodies according to the invention are mounted with their slider heads in the rail sections and can be slid from one of the rail sections over the corner into the other of the rail sections by means of the guide body.

The shape and size of the slider body is advantageously matched to the shape and in particular the height and width of the running channel of the rail sections accommodating the slider bodies in such a way that slider bodies arranged one behind the other cannot be slid so far onto one another that they are on top of one another or next to one another in the respective Rail section can jam. In this sense, it is advantageously provided that the height of the slider head is more than 50% of the height of the interior of the running channel of the respective rail section. Furthermore, it is favorable in this connection that the width of the slider head is more than 50% of that of the interior space of the running channel of the respective rail section. The width of the slider head is advantageously at least 80%, particularly preferably at least 90%, of the minimum opening width of the guide channels of the guide body.

[0034] FIG. 12 the area C from FIG. 11 enlarged.

1 shows a view of a rail arrangement 1 according to the invention, as it can be mounted on a building ceiling, for example. The rail arrangement 1 according to the invention has two rail sections 2 and 3 which, in this example, meet at a right angle 5 in order to form a corner 4 of the rail arrangement 1 . The two rail sections 2 and 3 each have mitred ends 9 and 10 . With these mitred ends 9 and 10 they are joined to form the corner 4 . However, as already explained at the outset, a corresponding corner 4 of the rail arrangement 1 could also be formed at an obtuse angle 5 . Preferred angular ranges for such obtuse angles have already been mentioned at the outset.

According to the invention, a guide body 6 is arranged within the rail sections 2 and 3 meeting in the corner 4, which is shown in FIGS. 3 and 4 detached from the rail sections 2 and 3. The guide body 6 has a rounded deflection surface 7 for deflecting slide bodies 8 guided in the rail arrangement 1 and attached or attachable to the curtain or curtain. By means of the guiding body 6, the slider bodies 8 are guided from one of the rail sections 2 over the corner 4 into the other of the rail sections 3. Each rail section 2 or 3 has a running channel 32 . This is delimited by the side walls 29 and the supporting shoulders 30 . Between the supporting shoulders 30 there is an elongate, slot-like or groove-like running channel opening 31.

As explained later with reference to FIGS. 11 and 12, the slider bodies 8 are slidably mounted with their slider heads 21 in the running channel opening 31 . In addition, the rail sections 2 and 3 also have fastening channels 33 with which they can be fastened to a ceiling or wall in a manner known per se.

In the case of the guide body 6 shown in FIGS. 3 and 4, in this exemplary embodiment it is a plug-in part which can be inserted into the rail sections 2 and 3 or specifically into their running channel openings 31. For this purpose, the guide body 6 has the guide body legs 11 and 12 . Each of the guide body legs 11 and 12 can be inserted into one of the mitred ends 9 or 10 of the rail sections 2 or 3, respectively. The size and shape of the rail sections 2 and 3 and the guide body 6 are advantageously matched to one another in such a way that the rail sections 2 and 3 can be connected to one another without play and in a form-fitting manner by means of the guide body 6 .

In this exemplary embodiment, guide body legs 11 and 12 each have a guide channel 13 or 14 . These two guide channels 13 and 14 lead to the rounded deflection surface 7 of guide body 6 . In FIG. 3 it can be seen how the opening widths 15 of the guide channels 13 and 14 each decrease in the direction towards the rounded deflection surface 7 . Each guide channel 13 or 14 is bounded by an outer boundary wall 16 and an inner boundary wall 17 . The rounded deflection surface 7 forms the transition between the outer channel delimiting walls 16. The inner channel delimiting walls 17 meet in the inner apex region 19. The inner apex region 19 is also advantageously rounded, as is also shown here. However, the radius of curvature of the apex region 19 is preferably significantly smaller than the radius of curvature of the deflection surface 7, which is designed to be rounded

Guide ramps 18 are advantageously formed on the inner channel boundary walls 17, as also shown here. These meet in the inner apex area 19 of the guide body 6 . Their ramp width 20 increases towards the inner apex area 19 . These guide ramps 18 and the associated narrowing of the guide channels 13, 14 in the direction of the rounded deflection surface 7 guide the slider bodies 8 on their way to the corner 4 to the deflection surface 7 and align them one behind the other in a line, so that they can be aligned particularly well along the deflection surface 7 can be guided around the corner 4.

5 to 9 now show representations of a preferred slider body 8 according to the invention, which can be used particularly well in rail arrangements 1 according to the invention. The slider body 8 has a slider head 21 and a slider base 23 . The slider head 21 is connected to the slider base 23 via the slider neck 22 . A fastening device 24 is located on the slider base 23, e.g. in the form of a hook or an eyelet. Curtains or curtains can be attached to this fastening device 24, which is known per se, in a manner known per se. FIG. 5 shows a perspective view of the slider body 8, FIG. 6 shows the area A from FIG. 5 on an enlarged scale. FIG. 7 shows a side view and FIG. 8 shows the area B from FIG. 7 on an enlarged scale. 9 shows a plan view of the slider head 21. It is clearly visible in FIGS. 5 to 9 that the slider head 21 is delimited on two opposite sides by rounded outer sides 25 and on two other opposite sides by flat outer sides 26. The rounded outer sides 25 can, for example, be elliptical in sections or in elliptical sections. The curvature of the outer sides 25 is preferably adapted to the radius of curvature of the deflection surface 7 . In particular in FIGS. 7 and 8 it is easy to see that in preferred embodiments such as the one shown here, the slider head 21 and/or the slider base 23 are preferably designed to be bevelled towards the slider neck 32 . The corresponding inclined surfaces on the slider head 21 and on the slider base 23 bear the reference number 28 here. A slot 27 can also be arranged in the slider head 21 .

10 now shows a sequence of slider bodies 8 arranged in the guide body 6 or its guide channels 13 and 14. It is easy to see how the slider bodies 8 arranged one behind the other rest with their flat outer sides 26 against one another. This makes it particularly easy to slide the slider body 8 and thus also the curtain attached thereto or the curtain attached thereto to move around the corner 4 of the rail arrangement 1 . The narrowing of the guide channels 13 and 14 in the direction of the rounded deflection surface 7 and the guide ramps 18 on the inner channel boundary walls 17 ensure that the slider bodies 8 with their slider heads 21 and their rounded outer sides 25 are guided to the deflection surface 7 and then accordingly on this be redirected. This works equally well in both directions. In addition, the curtain hanging on the slider bodies 8 or the corresponding curtain can both be pushed around the corner 4 and pulled. This is possible with the invention with very little effort and with very little resistance.

11 shows an example of a sectional view of the rail section 3 with the guide body 6 arranged therein and a slider body 8 arranged in the running channel 32. The slider head 21 of this slider body 8 is located in the running channel 32 and also in the guide channel 14 of the guide body 6 The slider head 21 rests with its inclined surfaces 28 on the supporting shoulders 30 of the rail section 3 . As shown here, the support shoulders 30 can also be beveled. The side walls 29 and the supporting shoulders 30 delimit the running channel 32, the running channel opening 31 being arranged between the supporting shoulders 30, as is known per se. Through this running channel opening 31, the slider neck 22 connects the slider base 23 arranged outside of the rail section 3 to the slider head 21 arranged in the running channel 32. On the side of the slider base 23 opposite the slider head 21 is the fastening device 24, on which the curtain or drape can be attached in can be hung in a known manner. All of this is shown in Fig. 12 enlarged. You can also see the fastening channel 33, with which the rail section 3 through

known means can be attached to a building ceiling or the like.

FIG. 12 clearly shows that the width of the slider head 21 is more than 50% of the width of the running channel 32 in preferred embodiments. The height of the slider head 21 is also advantageously more than 50% of the height of the running channel 32. This prevents the slider bodies 8 being pushed together in the respective rail section 2 or 3 from being pushed one above the other or next to one another and thus becoming jammed.

The width of the slider neck 22 and the width of the running channel opening 31 are preferably matched to one another in such a way that the slider body 8 with its slider head 21 cannot hit the end faces of the outer or inner channel boundary walls 16 or 17 when the slider head 21 is moving along the respective rail section 2 or 3 is inserted into the respective guide channel 13 or 14 of the guide body 6 .

A section through the rail section 2 results in an image that is analogous to that in FIGS. 11 and 12, so that it does not have to be shown again here.

To assemble the rail arrangement 11 according to the invention, the rail sections 2 and 3 can first be plugged together with the guide body 6 and then mounted on the ceiling in this form that is already forming the corner 4 . However, it is preferably provided that first one of the rail sections 2 is fastened to the building ceiling in a manner known per se. Subsequently, the sliding body 6 is inserted with the corresponding sliding body leg 11 or 12 in this rail section 2 or 2 already attached to the building ceiling. Alternatively, of course, this step can also be carried out before the first of the rail sections 2 or 3 is fastened to the building ceiling. The second rail section 2 or 3 can then be slid onto the still freely projecting guide body leg 11 or 12 until the mitred ends 9 and 10 of the rail sections 2 and 3 meet and thus form the corner 4 . Subsequently, the rail section 2 or 3 that has not yet been attached to the ceiling of the building can then be attached to it in a manner known per se.

The retraction of the slider body 8 in the running channel 32 can be done via a free end of the rail sections 2 or 3 or by a correspondingly large widening between the support shoulders 30 in a conventional manner.
