Description

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

Rail arrangement to lead hanging curtain around the corner.

There are numerous solutions in the prior art in which the rail arrangement has a rounded transition of some 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 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 so actually form a corner, to the effect that the curtains hanging on the slider bodies and/or

Curtains 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, attached or attachable to the curtain Slider bodies of one of the rail sections on the

Has corner away in the other of the rail sections.

A basic idea of the invention is therefore to let the rail sections 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 the slider body on which the curtain or curtain hangs or attached, along a deflection surface of rounded design, leads 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 across the corner into the respective

Rail sections can move. The invention has the advantage that in the rail assembly

optically viewed from the outside actually a corner in shape

of a right angle or an obtuse angle,

However, within the rail sections that meet, the guide body ensures that the slider bodies can be pushed or pulled from one rail section over the corner into the other rail section in a simple manner with relatively little resistance. 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 one that is pointed at a right angle or an obtuse angle

Corner.

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. Provision is particularly preferably made for the guide body to be an insertion part for insertion into the rail sections. The plug-in part and the rail sections are expediently designed in such a way that the rail sections form-fit with one another without play by means of the guide body

are connectable.

Rail arrangements according to the invention can be single-track but also multi-track. Single track means that the rail arrangement has only one running channel, in

which only a curtain or only a curtain with appropriate

Glider bodies can be performed. In the case of multi-track rail arrangements according to the invention, several curtains and/or drapes on corresponding slider bodies can, as is known per se, be arranged in two or more running channels of the rail arrangement, which are generally parallel to one another

be guided.

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 by 3D printing for custom-made products. The same materials and manufacturing methods can also be used for the sliding body

be used.

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. The rail sections or rails can also be made of plastic, wood or

composite material are produced.

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, the miter angles are then conveniently 45°, for obtuse

Angle preferably applies accordingly.

merged rail sections.

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. Conveniently located in each guide body leg

one or at least one of the guide channels.

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 directed towards the rounded deflection surface and away from it

be moved.

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, the rounded deflection surface forming a transition between

the outer channel boundary walls forms and on the inner

Channel boundary walls guide ramps are formed, which meet in one of the rounded extending deflection opposite, inner apex area of the guide body and the ramp width increases towards the inner apex area. Due to these guide ramps, the slider bodies are designed particularly well in the direction of rounded ones

Guided £ surface.

The inner apex area 1 is preferably also rounded. The radius of curvature of the inner apex area is advantageously smaller than the radius of curvature of the rounded shape

deflection surface.

In addition to the rail arrangement per se, 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. 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

Glider 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 this way it is achieved in particular that the curtain or curtain with the slider bodies attached to it not only moves from one of the rail sections across the corner into the other of the rail sections

can be pulled but also pushed particularly well.

In terms of simple pulling and pushing, particularly preferred variants provide that the slider head and/or the slider base, preferably each, for

Glider neck are designed bevelled.

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

Rail sections are movable.

The shape and size of the slider body is suitably 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 pushed onto one another so far that they can jam on top of one another or next to one another in the respective rail section . In that sense is

conveniently 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

Guide channels of the guide body.

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 angle ranges for such obtuse angles were initially

already mentioned.

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 guide 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 carrying shoulders 30 there is an elongated, slit-like or

groove-like running channel opening 31.

As explained below 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 attached in a manner known per se

can be attached to a ceiling or wall.

The guide body 6 shown in FIGS. 3 and 4 is, in this exemplary embodiment, 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 12 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 boundary walls 16. The inner channel boundary walls

17 meet in the inner apex area 19 on each other. Also

the inner apex region 19 is 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 rounded deflection surface 7. 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. Fig. 9 shows a top view of the slider head 21. In Figs. 5 to 9 it is clearly visible that the slider head 21 on two opposite

Sides of rounded outsides 25 and on two others

opposite sides of flat outer sides 26 is limited. 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

Slot 27 may be arranged.

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 in the invention with very little effort and with very little

resistance possible.

Fig. 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 mounting channel 33, with which the rail section 3 by means known per se to a building ceiling or

the like can be attached.

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 advantageously more than 50% of the height of the running channel 32. This prevents the pushing together of slider bodies 8 in the respective rail section 2 or 3, these above one another or

pushed next to each other and thus jammed.

The width of the slider neck 22 and the width of the running channel opening 31 are preferably coordinated 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 in the respective guide channel 13 or 14 of the

Guide body 6 is inserted.

A section through the rail section 2 results in an image analogous to that in FIGS. 11 and 12, so that this is the case here

does not have to be shown again.

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, which has not yet been attached to the building ceiling, can then be attached

these are attached in a conventional manner.

The retraction of the slider body 8 in the running channel 32 can have a free end of the rail sections 2 or 3 or by a correspondingly large widening between the

Carrying shoulders 30 done in a conventional manner.
