Description

Field of technology

The invention initially relates to a partition curtain for, for example, sports halls, multi-purpose halls, event and exhibition halls, industrial halls or halls, the partition curtain having two outer surfaces each formed by a curtain sheet, the curtain sheets being able to be gathered from a lowered state to a raised state a curtain web having a vertical height is composed of a plurality of web sections extending essentially horizontally in the lowered state, with one or more web sections of sound-absorbing material and one or more web sections of sound-absorbing material being arranged over the vertical height of each of the curtain webs, and wherein the Track sections made of sound-absorbing material of both curtain tracks are connected to one another in a width direction of the partition curtain by means of a bridging strip made of sound-absorbing material.

The invention further relates to a partition curtain (1) for, for example, sports halls (H), multi-purpose halls, event and exhibition halls, industrial halls or halls, the partition curtain (1) having two outer surfaces which are each formed by a curtain sheet (2, 3), wherein the curtain webs (2, 3) can be gathered from a lowered state to a raised state and a curtain web (2, 3) having a vertical height (c) is made up of several web sections (8, 9) extending essentially horizontally in the lowered state composed, wherein over the vertical height (c) of each of the curtain webs (2, 3) both one or more web sections (8) made of sound-absorbing material and one or more Track sections (9) made of sound-absorbing material are arranged, and in a lowered state of the partition curtain (1) between two track sections (8) made of sound-absorbing material of the two curtain tracks (2, 3) a substantially horizontally extending bridging strip (14) made of sound-absorbing Material is provided.

State of the art

Partition curtains of the type in question are known. These serve, for example, to separate large rooms, such as so-called three-compartment sports halls, into several, for example two or three smaller areas. Known curtains consist of at least two curtain webs which are horizontally spaced from one another in the lowered state and which have inner surfaces facing one another and outer surfaces facing one another. The curtain webs can be attached to a curtain support device, wherein the curtain support device can have one or more take-up shafts.

For example, for sports lessons in schools, as well as for the exercise units of the sports clubs that use the sports halls, good speech intelligibility in the part of a sports hall separated by the partition curtains is essential and indispensable. The DIN18032 - halls for gymnastics, games and multi-purpose use - therefore stipulates that partition curtains must contribute to the sound absorption of the hall parts. The same DIN 22 dB (A) values are prescribed for the sound insulation of partition curtains. The acoustic conditions in a sports hall are not only influenced by the sound insulation between the hall parts separated by partition curtains, but also very significantly by the duration of the reverberation times or the echo effect within the individual separated hall parts.

Accordingly, there is a need to specify partition curtains with which both the required sound insulation values can be achieved, as well as sufficient sound absorption to reduce the reverberation times.

For example, from the EP 1174 063 B1 Partition curtains of the type in question are known, with wall surfaces made of fleece-coated covering material, with which partition curtains a degree of sound absorption of about 0.15 can be achieved. Such partition curtains meet the requirements of DIN18032 Part 4 for sound absorption, whereby the attainable absorption value is not always suitable for ensuring the reverberation times according to DIN18041 in sports halls.

Also known are double-shell partition curtains, with or without an additional sound-absorbing textile insert, in which one wall surface is made of sound-absorbing material and the opposite is made of perforated material. If a correspondingly heavy covering material is used for the sound-absorbing wall surface, the 22 dB (A) required by DIN18032 Part 4 can be achieved. On the side of the perforated wall surface, the sound absorption values are partly very good and correspond to those of partition curtains perforated on both sides. The disadvantage of this construction is that the side of the partition curtain with the sound-absorbing wall surface is not sound-absorbing, with corresponding disadvantageous consequences for the reverberation times in the corresponding hall area.

The EP 3 225 774 A1 and EP 2 947 256 B1 refer to three- or four-shell partition curtains, in which one or two wall surfaces arranged on the inside ensure sound insulation of 22 dB (A) or more, two perforated wall surfaces arranged on the outside, for example fleece-coated covering material at the same time offer a sound absorption of 0.5 and above. Reverberation times according to DIN18041 can be achieved with this construction. However, there is the disadvantage that such a construction is more expensive and technically more complex than conventional partition curtains and that the constructions with a width of at least 0.40 m require greater installation widths in the area of the hall ceiling. In the case of the renewal of partition curtains in existing halls, this is often associated with great effort.

From the EP 3 372 743 A1 a partition curtain is known in which a bridging strip is designed with edge connecting means in the form of a zipper for connection to a web section.

Summary of the invention

Starting from the state of the art mentioned last, the object of the invention is to advantageously design a partition curtain with regard to the formation and interaction of a bridging strip with track sections.

This object is initially achieved with the subject matter of claim 1, whereby the aim is that the bridging strip, starting from a section of a first curtain web, extends to a connecting seam between two edge strips of the web sections of the second curtain web, is connected on or under the edge strip of the respective curtain web .

This object is also achieved in the subject matter of claim 2, the aim being that the bridging strip is in any case arranged unconnected with respect to one of the track sections.

A partition curtain is specified, which is preferably constructed with two shells, with a width between the curtain webs of preferably 200 to 400 mm, more preferably about 250 to 300 mm. Such a width essentially corresponds to the known constructions. At the same time, such a partition meets both requirements of DIN18032 Part 4, namely that of 22 dB (A) sound insulation and that of simultaneous sound absorption.

A sound absorption value of 0.5 and more can be achieved. Such a degree of sound absorption has proven itself. With an average sound-absorbing design of the other surrounding surfaces, such as the ceiling, floor and walls in the hall areas divided by the partition curtain according to the invention, reverberation times of less than 2 seconds can be achieved.

The sound-absorbing material can extend essentially alternately in the area of both curtain tracks, especially when the partition curtain is lowered, possibly with a bridging strip of sound-absorbing material crossing the space between the curtain tracks. This can also result in an overall continuous, preferably uninterrupted path of sound-absorbing material, with the continuity being able to result from a projection of the path sections of both curtain lengths made of sound-absorbing material and, if necessary, the bridging strips in the horizontal direction onto a common vertical plane. When a bridging strip is arranged, such a continuity can also result with regard to a vertical projection of these sound-absorbing material sections in a horizontal plane.

Each curtain track is composed of several horizontally extending track sections arranged one above the other, which Track sections viewed in the vertical direction of the curtain track can have a width of about 0.5 to 1.5 m. A curtain web can have two areas made of sound-absorbing and sound-absorbing material with reference to the vertical extension in the lowered state. Thus, according to a preferred embodiment, all track sections of a curtain track made of sound-absorbing material, viewed in the vertical direction, can be directly strung together, just as the track sections made of sound-absorbing material can be provided directly one behind the other in the vertical direction.

In this case, in a curtain track composed of an even number of track sections, an equal number of track sections made of sound-absorbing and sound-absorbing material can be provided, so that a total of half of each curtain track can be divided. The arrangement of these halves on sound-absorbing and sound-absorbing areas of the curtain webs can be chosen so that one sound-absorbing half is arranged opposite a sound-absorbing half of the other curtain web of the same partition curtain. With such a half division of the wall surfaces, in the middle of the partition curtain wall surfaces, seen in the vertical direction, the lower edge of the sound-absorbing half arranged on one side of the partition curtain in the upper region can be arranged essentially in the same horizontal plane as the upper edge of the opposite and correspondingly in the Sound-absorbing wall surface arranged in the lower area. At the connections of the web sections alternating from the sound-absorbing half to the sound-absorbing half, the bridging strip made of sound-absorbing material, which extends essentially horizontally when the partition curtain is lowered, can be provided.

The fact that the bridging strip, as proposed in one respect, can be arranged unconnected with respect to at least one of the track sections results in a favorable on-site installation of the partition curtain. The bridging strip does not have to be laboriously connected to the edge edges of the sound-absorbing web sections of both curtain webs, in particular sewn.

If, however, as also proposed, an arrangement is provided in which the bridging strip in the area of the edge strips of both curtain webs is connected to the edge strips and thus to the connecting areas of two web sections of a curtain web arranged one above the other in the vertical direction, such a bridging strip can take on the function of a horizontal traction means . The additional arrangement of a, for example, rope-shaped horizontal traction means, as is usually provided, can be dispensed with in the plane in which the bridging strip extends.

The end of the bridging strip facing an inside of a curtain web lies, as is preferred, on the top or bottom on or on the edge strip given by the two directly interconnected web sections of the curtain web. Thus, the edge strips of two web sections following one another in the vertical direction can initially be connected in the area of their edge strips, for example as a result of sewing. The facing end of the bridging strip is then placed on the edge strip package or under the edge strip package and also connected to it. Alternatively, taking into account the above-described arrangement of the end of the bridging strip, the connection of the edge strips of the two web sections to one another and the connection of the bridging strip with the edge strips in one process, for example a sewing process.

In particular, the bridging strips can consist of a comparatively stiff material such as a PVC sheet.

In this way, a sound-absorbing, continuous wall surface, which according to the invention extends, for example, half alternately across both wall surfaces, can be created. The extension alternately over both wall surfaces consequently also applies to the sound-absorbing halves of the partition curtain.

In particular in the case of curtain webs with an uneven number of web sections, but also possible in the case of curtain webs with an even number of web sections, an overlapping arrangement of the web sections made of sound-absorbing material of the curtain webs can be provided. In these cases, either the sound-absorbing area of a wall surface or the sound-absorbing area can have one or more track sections. This arrangement is reversed for the opposite curtain track. The larger area, consisting of sound-absorbing track sections, is preferably arranged when installing two partition curtains to the central hall area, which is delimited on two sides by partition curtains.

Thus, the stated values for sound insulation and sound absorption can be achieved in that the sound-absorbing areas on each side of the partition curtain overlap in the area of two or more sound-absorbing web sections. An arrangement of a bridging strip made of sound-absorbing material between the sound-absorbing areas of both Curtain tracks can be omitted. Insofar as sound-absorbing curtain web areas with different sizes result from an overlap of the sound-absorbing web sections, the partition curtains can be arranged in such a way that the curtain webs with the larger sound-absorbing components delimit the central area of triple sports halls. Depending on the requirements and acoustic requirements, the area of the vertical overlap, preferably when arranging track sections with a vertical width of less than 1.30 meters, can be increased or decreased.

The sound-absorbing web sections can be provided without, but preferably also with, an additional sound-absorbing surface, further for example, and preferably, with one made of fleece, felt, textile or some other sound-absorbing covering. This leads to an additionally assessed degree of sound absorption of, for example, about 0.15 for the surface.

The sound-absorbing web sections can also be provided without, but preferably also with, an additional sound-absorbing surface, here again preferably with one made of fleece, felt, textile or some other sound-absorbing covering. In addition, these sound-absorbing web sections are preferably provided with a perforation, preferably with a micro-perforation, and, if necessary, can be backed with an additional insert in the area between the curtain webs.

Thus, according to a possible embodiment, the bridging strip can be arranged unconnected with respect to both track sections made of sound-absorbing material of the two curtain tracks. In this way, an inexpensive and comparatively quick installation of the partition curtain can be achieved. There is no need for a complex connection of the bridging strip to the web sections, for example by sewing or the like.

In a further refinement, the track sections of both curtain tracks can be connected to one another, if necessary independently of their sound-effective properties, via pulling means which are formed like ropes and which extend essentially horizontally when the partition curtain is lowered. This horizontal traction means can be connected to a vertical traction means, but also to the opposite curtain tracks in the area of a connecting seam or the like between two track sections that follow one another in the vertical direction.

An optionally provided bridging strip can be connected to the horizontal traction means. Such a connection can be achieved by sewing, gluing, stapling, welding, screwing or riveting.

In this context, it proves to be particularly favorable to assembly if the bridging strip is only, i.e. exclusively, connected to the horizontal traction means. In this way, for example, the bridging strip can be attached or placed on the horizontal traction means that is preferably provided anyway.

Two web sections adjoining one another in the vertical direction when the partition curtain is in the lowered state can also have a connecting seam formed by edge strips lying one on top of the other, which extends essentially horizontally and towards an opposite curtain web. In this case, there can be an overlap of web section areas in the area of the edge strips lying on top of one another. In the area of such Overlapping can be a connection of the web sections, for example in the form of a seam. A connection can also be provided, for example, by riveting, welding or screwing, further if necessary using a profile, such as further, for example, to form a welt connection. In this regard, connections by zip fasteners or the like are also possible.

Such an overlapping connection seam can moreover be given both with a related connection of adjacent track sections made of sound-absorbing and sound-absorbing material as well as with adjacent track sections, both of which consist of sound-absorbing or sound-absorbing material.

In this case, a bridging strip can also run in the lowered state of the partition curtain at least on the edge side on one or both sides in a vertical overlap to a connecting seam or to edge regions of web sections lying on top of one another. Through this vertical overlap, the previously described continuity of the sound-absorbing layer can be achieved both in a horizontal projection and in a vertical projection.

The above-described horizontal traction means can also extend above or below the connecting seam and is further connected to the edge strips connected to one another in the area of the connecting seam, for example as a result of sewing, gluing or riveting.

In a preferred embodiment, the horizontal traction means extends in the lowered state of the partition curtain on the top of the superposed edge strips and the bridging strips below them Edge strips, this with vertical overlap to the assigned edge strips of both curtain strips.

In a further embodiment, the bridging section can also be formed in one piece, in addition, if necessary, and also preferably, of uniform material, with a track section made of sound-absorbing material of a curtain track. The web section made of sound-absorbing material of a curtain web is extended on the inside of the wall beyond the area of the edge strip used to connect the web sections in the direction of the inside of the opposite curtain web. This extended section forms the bridging strip, the free end section of which, as described above, is arranged to overlap the edge strips of two web sections of the opposite curtain web.

The freely overlapping end region of such a bridging strip formed in one piece with a web section can rest on the edge strip of the opposite curtain web or lie under the edge strip of the opposite curtain web. In principle, the freely overlapping end area can be aligned with the edge strip of several web elements. As a rule, this also requires the usual horizontal traction means.

In a further embodiment, this free end area can be connected to the edge strips of the opposite curtain web, for example by sewing. In such a case, due to the arrangement of the bridging strip that is correspondingly connected to the two curtain tracks, separate horizontal traction means in the plane in which the bridging strip is arranged can be dispensed with. The bridging strip can take on the function of a horizontal traction device. Separate horizontal traction means can accordingly be omitted.

Description of the embodiments

Is shown and described, initially with reference to Figure 1 , a partition curtain 1, such as this one, for example, in halls, in particular sports halls H (compare, for example, the schematic representation in Figure 2 ) or similar areas can be used. In this way, areas 17 of hall H or the like can be separated off and as far as possible avoided that noises are transmitted from one side of the hall area to the other.

The partition curtain 1 consists essentially of two curtain webs 2 and 3, which can be designated as wall surfaces, the partition curtain 1 being in the lowered state, as shown for example in FIG Figure 1 is shown extends substantially vertically.

The curtain tracks 2, 3 can be connected via horizontal traction means 4 in the form of cross-connectors fastened in the area of the inner surfaces of the curtain tracks 2 and 3 (see also FIGS Figures 3 to 5 ).

As further in Figure 1 Shown schematically, a gathering rail 5 can be provided in the region of the end facing the hall floor in the lowered state of the partition curtain 1. Such a gathering rail 5 extends in a preferred embodiment over the entire longitudinal extent of the partition curtain 1 (correspondingly in the direction of extent perpendicular to the plane of the drawing, for example with respect to the Figures 6 or 7th ) and acts preferably on the underside of the connection area between the curtain lengths 2 and 3.

The gathering rail 5 is attached to a vertical pulling means 6 in the form of a gathering cord. In the lowered state, the vertical traction means 6 penetrates the partition curtain 1 approximately in the middle between the curtain webs 2 and 3. Furthermore, the vertical traction means 6 can be attached at the end, ie on the ceiling side, to a preferably motor-driven, in particular electric-motor-driven winding shaft 7 or, in a deflected manner, to a winding device in the region of the motor.

The connecting means or traction means, such as in particular the vertical traction means 6, can be acted on by means of the motorized device. Thus, the partition curtain 1 can be pulled upwards under a hall ceiling while gathering the curtain webs 2 and 3 (see FIG. 6) or, starting from here, can be lowered in the direction of the hall floor.

The curtain webs 2 and 3 are divided into web sections 8 and 9 running transversely to the vertical extension and thus in the previously described longitudinal extension of the partition curtain 1. These track sections 8 and 9 are arranged one above the other for each curtain track 2, 3. The sum of the heights b of the track sections 8 and 9 of a curtain track 2, 3 results in the vertical height c of a curtain track 2, 3 in particular in the lowered position.

The essentially horizontally extending web sections 8 and 9 of a curtain web 2 or 3 when the partition curtain 1 is in the lowered state with a view of the broad side surface of a curtain web 2, 3 can be connected to one another via a connecting seam 12 formed in the area of superposed edge strips 10, 11. In the area of these edge strips 10, 11, the horizontal traction means 4 can then also be attached to the track sections 8 and 9.

The fastening of the horizontal traction means 4 to the edge strips 10, 11 in the area of the connecting seam 12 can be achieved by sewing, gluing, stapling, welding, screwing or riveting.

In a further embodiment, although not shown, the track sections 8 and 9 can also optionally be riveted, screwed, clamped, pressed or glued with the arrangement of profiles or strips.

The partition curtain 1 or the curtain webs 2, 3 are preferably fastened to a hall ceiling by means of support devices 13. The horizontal spacing of the supporting devices 13 from one another, observed in the state of use, essentially specifies the width a of the partition curtain 1 in the ceiling area, as is preferably also the width essentially corresponding to this width a in the bottom end region of the partition curtain 1. The width a of the partition curtain 1 can be approximately 0 , 2 to 0.4 m, further about 0.3 to 0.35 m.

According to the exemplary embodiments shown, areas SD with track sections 8 made of sound-absorbing material and areas SB with track sections 9 made of sound-absorbing material can be arranged over the vertical height c of each curtain track 2, 3. The sound-absorbing material for forming the web sections 8 in particular can be, for example, synthetic leather, plastic film, fleece or textile fabric. The material for the sound-absorbing web sections 9 can, as is also preferred, be perforated or perforated.

As can be seen from the illustrations, the curtain webs 2 and 3 can each have a sound-absorbing area SD, as well as being composed of a plurality of web sections 8 arranged one above the other a coherent sound-absorbing area SB made up of track sections 9 arranged directly one above the other in the vertical direction.

In the lowered state of the partition curtain 1, a sound-absorbing area SD of a curtain sheet 2 or 3 is essentially opposite a sound-absorbing area SB of the other curtain sheet 3 or 2.

Thus, according to the in Figure 7 The illustrated embodiment can be provided to provide the curtain webs 2 and 3 with respect to their vertical extension with a straight number of web sections 8 and 9 per curtain web 2, 3 each half with a sound-absorbing area SD and a sound-absorbing area SB. In the exemplary embodiment shown, a sound-absorbing area SD of a curtain web 2 or 3 extends over three web sections 8 and a sound-absorbing region SB over a further three web sections 9.

A sound-absorbing area SB of the other curtain sheet 3 of the same partition curtain 1 lies opposite the sound-absorbing area SD of the curtain web 2.

The edge strips 10 and 11 of the sound-absorbing web sections 8 of both curtain webs 2 and 3 can lie in vertical overlap with a bridging strip 14 made of a sound-absorbing material, which extends essentially horizontally in vertical section when the partition curtain according to FIG. 7 is lowered. This can be a comparatively stiff PVC strip which extends essentially between the inner sides of the curtain webs 2 and 3 facing one another.

From the sectional views in Figures 3 to 5 the vertical overlap of the edge strips 10, 11 in the area of the connecting seam 12 to the bridging strip 14 can be seen.

The bridging strip 14 can, as is also preferred, be arranged unconnected with respect to both track sections 8 made of sound-absorbing material or with respect to both edge strips 10, 11. Rather, only a connection of the bridging strip 14 to the horizontal traction means 4 is preferred in this regard. In this regard, a connection can be made by sewing, gluing, stapling, welding, screwing or riveting. Furthermore, the bridging strip 14 can have a corresponding opening for the throughput of the vertical traction means 6.

As in Figure 3 shown schematically, according to a possible embodiment, both the horizontal traction means 4 and the bridging strip 14 can be arranged on the top of the edge strips 10 and 11 or the connecting seam 12, or alternatively, as in FIG Figure 4 shown, each on the underside.

Preferably according to Figure 5 be to arrange the horizontal traction means 4 on the top of the edge strips 10 and 11 and the bridging strip 14 on the underside. As a further alternative, an arrangement is also possible in which the horizontal traction means 4 is provided on the underside and the bridging strip 14 is provided on the top of the edge strips 10 and 11.

In the representations of the Figures 3 to 5 the connection of the horizontal traction device 4 to the edge strips 10 or 11 is denoted by the number 15 and the connection of the bridging strip 14 to the horizontal traction device 4 is denoted by the number 16.

The schematic sectional views in Figures 19 to 22 show further alternative configurations, in particular with regard to the arrangement and design of the bridging strip 14.

Thus, according to the representations in the Figures 19 and 20 the bridging strip 14 can be formed in one piece with a track section 8 made of sound-absorbing material of one curtain web - here for example the curtain web 2 - so that the web section 8 extends beyond its edge strip 10 in the direction of the opposite curtain web 3.

The freely extending section of the web section 8 forms the bridging strip 14, the free end region 18 of which as shown in FIG Figure 19 can rest on the edge strips 10 and 11 of the opposite curtain web 3. In any case, this end region 18 is, as is preferred, in vertical overlap with the edge strips 10 and 11.

According to one possible embodiment, the end region 18 can rest on the edge strips 10 and 11 in a non-connected manner, according to the exemplary embodiments described above. The bridging strip 14 formed in this way can be connected to a horizontal traction means 4 in such a configuration.

As also shown, the end region 18 of the bridging strip 14 can also be connected to the edge strips 10 and 11 of the opposite curtain web 3, for example as a result of sewing. A connection seam 12 relating to this can in this case lead to the connection of the end region 18 and the edge strips 10 and 11 to one another.

In the case of a one-piece design of the bridging strip 14 with a web section 8, in the transition area from the web section 8 to the bridging strip 14 and the edge strip 10 formed here there is a connection via a connecting seam 12 to the edge strip 11 of the further web section 9 of the same curtain web 2, so that the so bridging strips 14 formed in one piece with the web section 8 can be connected to both curtain webs 2 and 3.

Such a bridging strip 14 can take on the function of a horizontal traction means, so that a separate horizontal traction means in the plane in which the bridging strip 14 is provided can be dispensed with.

In addition, this can also be the case with an arrangement of the end region 18 of a bridging strip 14 formed in one piece with a web section 8 on the underside of the edge strips 10 and 11 of the opposite curtain web 3 (cf. Figure 20 ).

The Figures 21 and 22 show embodiments in which separate bridging strips 14 are provided, which each end on the edge strips 10, 11 of the curtain webs 2, 3 (see Figure 21 ) or on the underside of the edge strips 10 and 11 are arranged (cf. Figure 22 ). According to the illustrations, these bridging strips 14 can be connected to the edge strips 10 and 11 via connecting seams 12, thus also connected to the curtain webs 2 and 3, so that these bridging strips 14 can also take on the function of horizontal traction means.

In the embodiment described, a sound-absorbing area SD accordingly extends vertically starting from the support device 13 below and in the area of the opposite curtain track another sound-absorbing area SD, essentially starting from the gathering rail 5 vertically upwards, with the edge edges of the sound-absorbing areas SD facing each other when projecting the two sound-absorbing areas SD into a common vertical plane essentially approx a common horizontal plane - based on the lowered state of the curtain 1 - extend. The bridging strip 14 extends in this plane or directly associated with this plane.

According to the invention, the above-described configuration and arrangement is not only obtained with a respective halved formation of the curtain webs 2 and 3 with sound-insulating and sound-absorbing areas. According to the representations in the Figures 7 to 11 An asymmetrical arrangement of sound-absorbing areas SD of both curtain lengths 2 and 3 can also be provided. This inevitably results in curtain webs 2, 3 with an uneven number of web sections 8, 9, for example according to the illustration in FIG. 9. But even in the case of curtain webs 2, 3 with an even number of web sections 8, 9, such an asymmetrical arrangement as shown in FIGS Figures 7 and 8 is shown, possible.

Thus, with an exemplary number of a total of six web sections 8, 9 of a curtain web 2 or 3, two, three or four directly connected web sections 8 can form a sound-absorbing area SD of a curtain web 2 or 3, while the same curtain web 2 or 3 four, three or can have two track sections 9 to form a sound-absorbing area SB.

A sound-absorbing area SD of a curtain web 2, consisting of a plurality of web sections 8, can be opposite to a sound-absorbing region SB of the further curtain web 3 with the same number of web sections 9.

With such an asymmetrical division of sound-absorbing areas SD and sound-absorbing areas SB, the curtain webs 2 or 3 with the larger-area sound-absorbing areas SB of two partition curtains 1 for the division of a central area 17 of a sports hall H are preferably arranged facing each other, so that area 17 two sides of partition curtains 1 with facing large sound-absorbing areas SB is limited (cf. Figure 2 ).

While in the above-described embodiments of Figures 1 to 11 the combined vertical heights b of the track sections 8 made of sound-absorbing material of both curtain tracks 2, 3 as a whole - with reference to the lowered state of the partition curtain - essentially result in the vertical height c of the partition curtain 1, these combined vertical heights b of the sound-absorbing track sections 8 exceed this total Height c in the in the Figures 12 to 18 illustrated embodiments.

Thus, the number of web sections 8 of a curtain web 2 lined up in a vertical direction can exceed the number of web sections 9 for forming the sound-absorbing area of the opposite curtain web 3 by one or more.

This results in an overlapping arrangement of the track sections 8 made of sound-absorbing material of the two curtain tracks 2 and 3, from which furthermore an overlap height u results which can correspond to the vertical height b of at least one web section 8.

Such an arrangement can result in both an even and an odd number of track sections 8, 9 of a curtain track 2, 3.

Thus, in one embodiment, a sound-absorbing area SD of a curtain web 2 can extend, starting from the support device 13, over three of a total of five web sections 8, 9. The sound-absorbing area SD of the other curtain web 3 of the partition curtain 1 can also extend vertically upwards over three web sections 8 starting from the gathering rail 5. An essentially approximately vertically central overlap zone Z can thus result with the overlap height u.

According to the representation in Figure 13 a curtain web 2 have a sound-absorbing area SB, which consists only of a web section 9, for example assigned to the gathering rail 5, while the remaining area of the same curtain web 2 is designed to be sound-absorbing.

The Figures 14 to 16 show in this context further embodiments with an overlap zone Z each extending over a web section 8.

These further embodiments with overlapping sound-absorbing areas SD have in common that no bridging strip 14 has to be arranged between the curtain webs 2, 3 in these. The overlap in the overlap zone Z proves to be sufficient to comply with the requirements described.

In this case, when both curtain lengths 2 and 3 are projected into a common vertical plane, there is also a sound insulation which extends completely over the entire height and width and which is doubled in the overlap zone Z in this projection.

As further from the representations in the Figures 17 and 18th As can be seen, the overlap zone Z can also extend over several successive web sections 8, for example over two web sections 8 (see FIG Figure 17 ) or over three or four track sections 8 (see Figure 18).

Correspondingly, larger overlap heights u or larger overlap zones Z result.

These embodiments are particularly recommended for partition curtains 1 with six or more track sections 8, 9 per curtain track 2, 3 with a height b of the track sections 8, 9 of preferably less than 1.30 m, more preferably about 0.65 m. Figure 18 shows schematically such an embodiment with a height b of 0.65 m.
