Description

field of technology

[0001] The invention relates initially to a partition curtain for, for example, sports halls, multi-purpose halls, event and exhibition halls, industrial halls or auditoriums, wherein the partition curtain has two outer surfaces, each formed by a curtain panel, wherein the curtain panels can be gathered from a lowered state to a raised state, and a curtain panel having a vertical height is composed of several panel sections that extend substantially horizontally in the lowered state, wherein one or more panel sections made of sound-insulating material and one or more panel sections made of sound-absorbing material are arranged over the vertical height of each of the curtain panels, and wherein the panel sections made of sound-insulating material of both curtain panels are connected to each other in a width direction of the partition curtain by means of a bridging strip made of sound-insulating material.

[0002] The invention further relates to a partition curtain for, for example, sports halls, multi-purpose halls, event and exhibition halls, industrial halls or auditoriums, wherein the partition curtain has two outer surfaces, each formed by a curtain panel, wherein the curtain panels can be gathered from a lowered state to a raised state, and a curtain panel having a vertical height is composed of several panel sections extending substantially horizontally in the lowered state, wherein one or more panel sections made of sound-insulating material and one or more panel sections made of sound-absorbing material are arranged over the vertical height of each of the curtain panels.and wherein, in a lowered state of the dividing curtain, a substantially horizontal bridging strip of sound-absorbing material is provided between two sections of the curtain made of sound-absorbing material. State of the art

[0003] Dividing curtains of the type in question are known. These serve, for example, to divide large spaces, such as triple gymnasiums, into several smaller areas, for instance, two or three. Known curtains consist of at least two curtain panels spaced horizontally apart when lowered, with facing inner surfaces and opposing outer surfaces. The curtain panels can be suspended from a curtain support device, which may have one or more winding shafts.

[0004] For physical education classes in schools, as well as for the training sessions of sports clubs that also use the sports halls, good speech intelligibility in the section of the hall separated by dividing curtains is of essential and indispensable importance. DIN 18032 – Halls for gymnastics, games and multi-purpose use – therefore stipulates that dividing curtains must contribute to the sound absorption of the hall sections. The same DIN standard specifies a sound insulation value of 22 dB(A) for dividing curtains. However, in addition to the sound insulation between the sections separated by dividing curtains, the acoustic conditions in a sports hall are also significantly influenced by the duration of the reverberation time or the echo effect within the individual separated sections.

[0005] There is therefore a need to specify partition curtains that can achieve both the required sound insulation values ​​and sufficient sound absorption to reduce reverberation times.

[0006] For example, partition curtains of the type in question are known from EP 1 174 063 B1, with wall surfaces made of fleece-coated covering material, with which a sound absorption coefficient of approximately 0.15 can be achieved. Such partition curtains meet the requirements of DIN 18032 Part 4 for sound absorption, although the achievable absorption value is not always suitable to ensure the reverberation times according to DIN 18041 in sports halls.

[0007] Double-layered partition curtains are also known, with or without an additional sound-absorbing textile insert, in which one wall surface consists of sound-absorbing material and the opposite surface of perforated material. By using a sufficiently heavy covering material for the sound-absorbing wall surface, the 22 dB(A) required by DIN 18032 Part 4 can be achieved. On the side with the perforated wall surface, the sound absorption values ​​are sometimes very good and correspond to those of partition curtains with perforations on both sides. The disadvantage of this design is that the side of the partition curtain with the sound-absorbing wall surface is not sound-absorbing, with corresponding adverse effects on the reverberation time in the corresponding hall area.

[0008] EP 3 225 774 A1 and EP 2 947 256 B1 refer to three- and four-layer partition curtains, respectively, in which one or two inner wall surfaces ensure sound insulation of 22 dB(A) or higher, while two outer perforated wall surfaces, made of, for example, fleece-coated fabric, simultaneously provide sound absorption of 0.5 and higher. Reverberation times according to DIN 18041 can be achieved with this design. However, this design has the disadvantage of being more expensive and technically more complex to manufacture than conventional partition curtains, and requires greater installation widths in the hall ceiling area for a minimum width of 0.40 m. Replacing partition curtains in existing halls is often a very costly and complex process.

[0009] From EP 3 372 743 A1 a partition curtain is known in which a bridging strip is designed with edge connecting means designed as a zipper for connection to a track section.

[0010] From EP 3 416 161 A1 a dividing curtain is known in which the bridging strips extend between the boundaries of adjacent railway sections. Summary of the invention

[0011] Starting from the aforementioned prior art, the invention aims to advantageously design a dividing curtain with regard to the formation and interaction of a bridging strip with railway sections.

[0012] This problem is solved in the subject matter of claim 1, wherein the focus is on two sections of the curtain which are adjacent to each other in a vertical direction when the curtain is lowered having a connecting seam formed by overlapping edge strips, wherein the edge strips extend substantially horizontally and onto an opposite curtain panel, and wherein the bridging strip extending from a section of a first curtain panel to the connecting seam between the two edge strips of the sections of the second curtain panel is connected on or under the edge strip of the respective curtain panel.

[0013] This problem is also solved in the subject matter of claim 2, wherein the bridging strip is arranged unconnected with respect to at least one of the track sections and the track sections of both curtain tracks are connected to each other via rope-like traction elements which extend substantially horizontally when the dividing curtain is lowered, wherein a bridging strip is connected to the horizontal traction element.

[0014] A partition curtain is described, consisting of two layers, with a width between the curtain panels preferably 200 to 400 mm, and more preferably approximately 250 to 300 mm. This width essentially corresponds to known designs. At the same time, such a partition curtain fulfills both requirements of DIN 18032 Part 4, namely the requirement for 22 dB(A) sound insulation and the requirement for simultaneous sound absorption.

[0015] A sound absorption coefficient of 0.5 and higher is achievable. Such a sound absorption coefficient has proven effective. With an average sound-absorbing design of the other surrounding surfaces, such as the ceiling, floor, and walls in the hall areas separated by the partition curtain according to the invention, reverberation times of less than 2 seconds are achievable.

[0016] The sound-absorbing material can extend, particularly when the dividing curtain is lowered, essentially alternating between the two curtain panels, optionally spanning the gap between them with a bridging strip of sound-absorbing material. This can result in a continuous, preferably uninterrupted, layer of sound-absorbing material, with the continuity being defined by a horizontal projection of the sound-absorbing material sections of both curtain panels and, optionally, the bridging strips onto a common vertical plane. If a bridging strip is used, such continuity can also be defined by a vertical projection of these sound-absorbing material sections onto a horizontal plane.

[0017] Each curtain panel is composed of several horizontally extending sections arranged one above the other, which, viewed vertically, can have a width of approximately 0.5 to 1.5 m. In its lowered state, a curtain panel can have two sections made of sound-insulating and sound-absorbing material. According to a preferred embodiment, all sections of a curtain panel made of sound-insulating material can be arranged directly adjacent to each other in the vertical direction, just as the sections made of sound-absorbing material can be arranged directly one behind the other in the vertical direction.

[0018] In a curtain panel consisting of an even number of sections, an equal number of sections can be made of sound-insulating and sound-absorbing material, resulting in an overall 50 / 50 division per panel. The arrangement of these halves of the sound-insulating and sound-absorbing sections of the curtain panels can be such that each sound-insulating half is positioned opposite each sound-absorbing half of the other panel of the same partition curtain. With such a 50 / 50 division of the wall surfaces, the lower edge of the sound-insulating half located on one side of the partition curtain, viewed vertically, can be positioned in essentially the same horizontal plane as the upper edge of the sound-insulating wall surface on the opposite side, located in the lower section.At the junctions of the railway sections, where the sound-absorbing half transitions to the sound-insulating half, a bridging strip made of sound-insulating material, extending essentially horizontally when the dividing curtain is lowered, may be provided.

[0019] Because the bridging strip, as proposed in one respect, can be arranged unconnected with respect to at least one of the track sections, the dividing curtain can be installed more easily on site. The bridging strip does not need to be laboriously connected to the edges of the sound-absorbing track sections of both curtain tracks, in particular by sewing.

[0020] However, if, as further proposed, an arrangement is provided in which the bridging strip is connected to the edge strips of both curtain tracks in the area of ​​the edge strips and thus to the connection areas of two vertically superimposed track sections of a curtain track, such a bridging strip can assume the function of a horizontal tensioning element. The additional arrangement of, for example, a cable-shaped horizontal tensioning element, as is usually provided, can be omitted in the plane in which the bridging strip extends.

[0021] The end of the bridging strip facing the inside of a curtain panel rests on top or bottom of the edge strip formed by the two directly connected sections of the curtain panel. The edge strips of two vertically consecutive panel sections can initially be joined in the area of ​​their edge strips, for example, by sewing. The end of the bridging strip facing the inside of the edge strip is then placed on or under the edge strip bundle and joined to it. Alternatively, taking into account the aforementioned arrangement of the bridging strip's end, the joining of the edge strips of the two panel sections to each other and the joining of the bridging strip to the edge strips can be carried out in a single operation, such as a sewing operation.

[0022] In particular, the bridging strips can be made of a relatively stiff material, such as a PVC sheet.

[0023] This allows for the creation of a sound-insulating, continuous wall surface, which, according to the invention, extends, for example, alternately across both wall surfaces in equal parts. The alternating extension across both wall surfaces logically also applies to the sound-absorbing halves of the partition curtain.

[0024] Particularly with curtain panels that have an odd number of sections, but also possible with curtain panels that have an even number of sections, an overlapping arrangement of the sound-absorbing material sections can be provided. In these cases, either the sound-absorbing area of ​​a wall surface or the sound-insulating area can have one or more additional panels. This arrangement is reversed on the opposite curtain panel. The larger area consisting of sound-absorbing sections is preferably arranged when two dividing curtains are installed to separate the central hall area, which is bordered on two sides by dividing curtains.

[0025] The aforementioned sound insulation and sound absorption values ​​can be achieved by overlapping the sound-insulating areas on each side of the dividing curtain in the region of two or more sound-insulating sections. A bridging strip of sound-insulating material between the sound-insulating areas of both curtain sections is therefore unnecessary. If the overlapping sound-insulating sections result in sound-absorbing curtain sections of different sizes, the dividing curtains can be arranged so that the curtain sections with the larger sound-absorbing areas define the central area of ​​triple gymnasiums. Depending on the requirements and acoustic specifications, the area of ​​vertical overlap can be increased or decreased, preferably when using curtain sections with a vertical width of less than 1.30 meters.

[0026] The sound-insulating track sections can be provided without, but preferably also with, an additional sound-absorbing surface, for example, and preferably, with a surface made of fleece, felt, textile, or another sound-absorbing material. This results in an additional sound absorption coefficient of, for example, approximately 0.15 for the surface.

[0027] The sound-absorbing sections of the fabric can be provided without, but preferably also with, an additional sound-absorbing surface, preferably made of non-woven fabric, felt, textile, or another sound-absorbing material. In addition, these sound-absorbing sections are preferably perforated, preferably with micro-perforations, and can, if required, be backed with an additional insert in the area between the curtain panels.

[0028] According to one possible design, the bridging strips between the two curtain sections can be made of sound-absorbing material and arranged independently of each other. This allows for inexpensive and relatively quick installation of the dividing curtain. There is no need for complex joining of the bridging strips to the curtain sections, for example by sewing or similar methods.

[0029] The sections of both curtain panels can be connected to each other by rope-like tension members, which, when the dividing curtain is lowered, extend essentially horizontally, possibly regardless of their sound-absorbing properties. This horizontal tension member can be connected to a vertical tension member, and also to the opposing curtain panels in the area of ​​a seam or similar joint between two vertically successive panel sections.

[0030] A bridging strip, arranged independently of one of the track sections, is connected to the horizontal traction element. Such a connection can be achieved by sewing, gluing, stapling, welding, screwing, or riveting.

[0031] In this context, it proves particularly advantageous for assembly if the bridging strip is connected only, i.e., exclusively, to the horizontal tensioning element. This allows, for example, the bridging strip to be attached or placed solely on the horizontal tensioning element, which is preferably already provided.

[0032] Two vertically adjacent sections of the curtain, when lowered, can also have a connecting seam formed by overlapping edge strips, extending essentially horizontally to an opposite curtain panel. This overlapping of the curtain sections may occur. Within this overlap, the sections can be joined, for example, by a seam. Alternatively, a connection can be made by riveting, welding, or screwing, possibly using a profile, such as a welted connection. Connections using zippers or similar devices are also possible.

[0033] Such an overlapping seam can also be present in the case of a connection between adjacent track sections made of sound-insulating and sound-absorbing material, as well as in the case of adjacent track sections which both consist of sound-insulating or sound-absorbing material.

[0034] Furthermore, a bridging strip can, at least at the edges of the lowered dividing curtain, overlap vertically on one or both sides to a connecting seam or to overlapping edge areas of track sections. This vertical overlap ensures the aforementioned continuity of the sound-insulating layer in both horizontal and vertical projections.

[0035] The aforementioned horizontal tensile element can also extend above or below the joint seam, and is further connected to the edge strips connected to each other in the area of ​​the joint seam, for example by sewing, gluing or riveting.

[0036] In a preferred embodiment, the horizontal tensioning element extends, in the lowered state of the dividing curtain, above the overlapping edge strips and the bridging strips below these edge strips, with vertical overlap to the associated edge strips of both curtain panels.

[0037] In a further embodiment, the bridging section can also be formed in one piece, and optionally, preferably, as a single material, with a section of sound-absorbing material from a curtain wall. The section of sound-absorbing material from the curtain wall is extended on the inside of the wall beyond the area of ​​the edge strip used to connect the sections, towards the inside of the opposite curtain wall. This extended section forms the bridging strip, the free end section of which, as described above, is arranged overlapping the edge strips of two sections of the opposite curtain wall.

[0038] The freely overlapping end section of such a bridging strip, formed as a single unit with a track section, can rest on or beneath the edge strip of the opposite track. In principle, the freely overlapping end section can be aligned with the edge strip of several track elements. This usually requires additional horizontal tensioning devices.

[0039] In a further embodiment, this free end area can be connected to the edge strips of the opposite curtain panel, for example by sewing. In such a case, due to the bridging strip being connected to both curtain panels, separate horizontal tensioning elements in the plane in which the bridging strip is located can be omitted. The bridging strip can thus assume the function of a horizontal tensioning element. Separate horizontal tensioning elements can therefore be eliminated. Brief description of the drawings

A part that is explained only in relation to one of the exemplary embodiments and is not replaced by another part in a further exemplary embodiment due to the special feature highlighted therein, is thus also described for this further exemplary embodiment as a possible existing part.

Description of the embodiments

[0041] The presentation and description initially refers to Figure 1 , a dividing curtain 1, such as this one in halls, especially sports halls H (compare, for example, the schematic representation in Figure 2 ) or similar areas. This allows areas such as Hall H (or similar) to be separated, thus largely preventing noise from being transmitted from one side of the hall to the other.

[0042] The partition curtain 1 essentially consists of two curtain panels 2 and 3, which can be described as wall surfaces, wherein the partition curtain 1, when lowered, as is the case, for example, in Figure 1 It is shown to extend essentially vertically.

[0043] The curtain panels 2, 3 can be connected by horizontal tension elements 4 in the form of cross connectors, each attached in the area of ​​the inner surfaces of the curtain panels 2 and 3 (see also the Figures 3 to 5 ).

[0044] What's next in Figure 1 As shown schematically, a gathering track 5 can be provided in the area of ​​the end of the partition curtain 1 facing the hall floor when lowered. In a preferred embodiment, such a gathering track 5 extends over the entire longitudinal extent of the partition curtain 1 (correspondingly in the direction of extension perpendicular to the plane of the drawing, for example with respect to the Figure 6 or 7 ) and acts preferentially on the underside of the connection area between the curtain panels 2 and 3.

[0045] The curtain track 5 is attached to a vertical drawstring 6 in the form of a drawstring cord. When lowered, the vertical drawstring 6 passes through the dividing curtain 1 approximately midway between the curtain panels 2 and 3. Furthermore, the vertical drawstring 6 can be attached at its end, i.e., at the ceiling end, to a winding shaft 7, preferably driven by a motor, particularly an electric motor, or deflected to a winding device in the area of ​​the motor.

[0046] The motorized device allows control of the connecting elements or tensioning elements, in particular the vertical tensioning element 6. This allows the partition curtain 1 to be pulled upwards under a hall ceiling by gathering the curtain panels 2 and 3 (see Figure 6) or lowered from there towards the hall floor.

[0047] Curtain panels 2 and 3 are subdivided into sections 8 and 9, which run perpendicular to the vertical extent and thus along the longitudinal extent of the dividing curtain 1 as described above. These sections 8 and 9 are arranged one above the other in each curtain panel 2, 3. The sum of the heights b of sections 8 and 9 of a curtain panel 2, 3 gives the vertical height c of a curtain panel 2, 3, particularly in the lowered position.

[0048] The curtain sections 8 and 9 of a curtain panel 2 or 3, which extend essentially horizontally when the dividing curtain 1 is lowered and viewed from the broad side surface of a curtain panel 2, 3, can be connected to each other via a connecting seam 12 formed in the area of ​​overlapping edge strips 10, 11. The horizontal tensioning elements 4 can then also be attached to the curtain sections 8 and 9 in the area of ​​these edge strips 10, 11.

[0049] The attachment of the horizontal tensioning elements 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.

[0050] In a further embodiment, although not shown, track sections 8 and 9 may also be riveted, screwed, clamped, pressed or glued together, if necessary when profiles or strips are arranged.

[0051] The partition curtain 1, or the curtain panels 2, 3, are preferably attached to a hall ceiling via support structures 13. The horizontal distance between the support structures 13, as considered in the operational state, essentially determines the width a of the partition curtain 1 in the ceiling area, as preferably also the width at the floor-side end of the partition curtain 1, which corresponds essentially to this width a. The width a of the partition curtain 1 can be approximately 0.2 to 0.4 m, and further approximately 0.3 to 0.35 m.

[0052] According to the illustrated embodiments, areas SD with panel sections 8 made of sound-insulating material and areas SB with panel sections 9 made of sound-absorbing material can be arranged along the vertical height c of each curtain panel 2, 3. The sound-insulating material for forming, in particular, the panel sections 8 can be, for example, artificial leather, plastic film, non-woven fabric, or even textile fabric. The material for the sound-absorbing panel sections 9 can, preferably, be perforated.

[0053] As can be seen from the illustrations, the curtain panels 2 and 3 can each have a sound-insulating area SD consisting of several superimposed panel sections 8, as well as a continuous sound-absorbing area SB consisting of panel sections 9 arranged directly above one another in the vertical direction.

[0054] In the lowered state of the dividing curtain 1, a sound-insulating area SD of one curtain panel 2 or 3 is essentially opposite a sound-absorbing area SB of the other curtain panel 3 or 2.

[0055] Thus, according to the in Figure 7 In the illustrated embodiment, the curtain panels 2 and 3 are provided with a sound-insulating area SD and a sound-absorbing area SB, each covering half of their vertical extent with a straight number of panel sections 8 and 9. In the illustrated embodiment, a sound-insulating area SD of a curtain panel 2 or 3 extends over three panel sections 8, and a sound-absorbing area SB extends over a further three panel sections 9.

[0056] The sound-insulating area SD of the curtain panel 2 is opposite a sound-absorbing area SB of the other curtain panel 3 of the same dividing curtain 1.

[0057] The edge strips 10 and 11 of the sound-insulating sections 8 of both curtain panels 2 and 3 can be vertically overlapped by a bridging strip 14 made of a sound-insulating material, which extends essentially horizontally in the vertical section of the dividing curtain as shown in Figure 7 when lowered. This bridging strip can be a relatively stiff PVC strip that extends essentially between the facing inner surfaces of the curtain panels 2 and 3.

[0058] From the sectional views in the 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 is visible.

[0059] The bridging strip 14 can, preferably, be arranged unconnected with respect to both track sections 8 made of sound-absorbing material or with respect to both edge strips 10, 11. However, a connection of the bridging strip 14 to the horizontal traction element 4 is preferred. This connection can be made by sewing, gluing, stapling, welding, screwing, or riveting. Furthermore, the bridging strip 14 can have a corresponding opening to allow passage of the vertical traction element 6.

[0060] As in Figure 3 As shown schematically, according to one possible embodiment, both the horizontal tensioning element 4 and the bridging strip 14 can be arranged on the upper side of the edge strips 10 and 11 or the connecting seam 12, or alternatively, as in Figure 4 shown, each on the underside.

[0061] Preferably according to Figure 5The horizontal tension member 4 is to be arranged on the upper side of the edge strips 10 and 11, and the bridging strip 14 on the underside. Alternatively, an arrangement is also possible in which the horizontal tension member 4 is on the underside and the bridging strip 14 is on the upper side of the edge strips 10 and 11.

[0062] In the depictions of the Figures 3 to 5 The connection of the horizontal traction element 4 with the edge strips 10 or 11 is designated by the number 15 and the connection of the bridging strip 14 to the horizontal traction element 4 by the number 16.

[0063] The schematic sectional views in the Figures 19 to 22 further alternative designs are shown, in particular with regard to the arrangement and design of the bridging strip 14.

[0064] Thus, according to the descriptions in the Figures 19 and 20the bridging strip 14 is formed in one piece with a track section 8 made of sound-absorbing material of one curtain track - here for example the curtain track 2 - so that the track section 8 extends beyond its edge strip 10 in the direction of the opposite curtain track 3.

[0065] The freely overlapping section of track section 8 forms the bridging strip 14, the free end area 18 of which is shown in the illustration in Figure 19 This end area 18 can rest on the edge strips 10 and 11 of the opposite curtain panel 3. In any case, this end area 18 is preferably in vertical overlap with the edge strips 10 and 11.

[0066] In one possible embodiment, the end section 18 can rest on the edge strips 10 and 11 without being connected, as described in the exemplary embodiments above. The bridging strip 14 thus formed can be connected to a horizontal tension member 4 in such a configuration.

[0067] As also shown, the end section 18 of the bridging strip 14 can be connected to the edge strips 10 and 11 of the opposite curtain panel 3, for example by sewing. In this case, a corresponding connecting seam 12 can lead to the connection of the end section 18 and the edge strips 10 and 11 to each other.

[0068] In the case of a one-piece design of the bridging strip 14 with a track section 8, a connection is formed in the transition area from the track section 8 into the bridging strip 14 and the edge strip 10 formed here via a connecting seam 12 with the edge strip 11 of the further track section 9 of the same curtain track 2, so that the bridging strip 14 formed in this way, which is shaped in one piece with the track section 8, can be connected with both curtain tracks 2 and 3.

[0069] Such a bridging strip 14 can take over the function of a horizontal traction element, so that a separate horizontal traction element in the plane in which the bridging strip 14 is provided can be omitted.

[0070] This can also occur when the end section 18 of a bridging strip 14 formed integrally with a track section 8 is arranged on the underside of the edge strips 10 and 11 of the opposite curtain track 3 (compare Figure 20 ).

[0071] The Figures 21 and 22 shown embodiments in which separate bridging strips 14 are provided, each of which rests at its end on the edge strips 10, 11 of the curtain panels 2, 3 (see Figure 21 ) or are arranged on the underside of the edge strips 10 and 11 (compare Figure 22 ). These bridging strips 14 can be connected to the edge strips 10 and 11 via connecting seams 12 as shown in the illustrations, and thus also connected to the curtain panels 2 and 3, so that these bridging strips 14 can also take over the function of horizontal tensioning elements.

[0072] In the described configuration, a sound-insulating area SD extends vertically downwards from the support structure 13, and in the area of ​​the opposite curtain track, another sound-insulating area SD extends vertically upwards, essentially from the curtain track 5. The edge edges of the two sound-insulating areas SD, which would point towards each other when projected onto a common vertical plane, extend approximately in a common horizontal plane – relative to the lowered state of the dividing curtain 1. The bridging strip 14 extends in this plane or directly adjacent to it.

[0073] The aforementioned design and arrangement results not only from a mutually equal configuration of the curtain panels 2 and 3 with sound-insulating and sound-absorbing areas, according to the invention. As shown in the illustrations in the Figures 7 to 11 An asymmetrical arrangement of sound-absorbing zones SD of both curtain panels 2 and 3 can also be provided. This inevitably results in curtain panels 2, 3 with an odd number of panel sections 8, 9, for example, as shown in Figure 9. However, such an asymmetrical arrangement is also possible in curtain panels 2, 3 with an even number of panel sections 8, 9, as shown in the Figures 7 and 8 As depicted, it is possible.

[0074] For example, with a total of six superimposed track sections 8, 9 of a curtain track 2 or 3, two, three or four directly connected track sections 8 can form a sound-insulating area SD of a curtain track 2 or 3, while the same curtain track 2 or 3 can have four, three or two track sections 9 to form a sound-absorbing area SB.

[0075] A sound-insulating area SD of a curtain track 2, consisting of a plurality of track sections 8, can be opposite a sound-absorbing area SB of the further curtain track 3 with the same number of track sections 9.

[0076] In such an asymmetrical division of sound-insulating areas SD and sound-absorbing areas SB, the curtain panels 2 and 3 with the larger sound-absorbing areas SB of two dividing curtains 1 are preferably arranged facing each other to divide a central area 17 of a sports hall H, so that the area 17 is bounded on two sides by dividing curtains 1 with large sound-absorbing areas SB facing them (compare Figure 2 ).

[0077] While in the previously described embodiments of the Figures 1 to 11The combined vertical heights b of the track sections 8 made of sound-absorbing material of both curtain tracks 2, 3 – with reference to the lowered state of the dividing curtain – essentially equal the vertical height c of the dividing curtain 1. These combined vertical heights b of the sound-absorbing track sections 8 exceed this total height c in the Figures 12 to 18 depicted embodiments.

[0078] Thus, the number of vertically arranged track sections 8 of a curtain track 2 can exceed the number of track sections 9 to form the sound-absorbing area of ​​the opposite curtain track 3 by one or more.

[0079] This results in an overlapping arrangement of the track sections 8 made of sound-absorbing material of both curtain tracks 2 and 3, which further results in an overlap height u that can correspond to the vertical height b of at least one track section 8.

[0080] Such an arrangement can occur with both an even and an odd number of track sections 8, 9 of a curtain track 2, 3.

[0081] In one embodiment, a sound-absorbing zone SD of a curtain track 2 can extend from the support structure 13 over three of the five track sections 8, 9. The sound-absorbing zone SD of the other curtain track 3 of the dividing curtain 1 can also extend vertically upwards over three track sections 8 from the guide rail 5. This can result in an overlap zone Z that is essentially centered vertically, with an overlap height of u.

[0082] According to the presentation in Figure 13a curtain track 2 has a sound-absorbing area SB, which consists only of one track section 9, for example assigned to the roller track 5, while the remaining area of ​​the same curtain track 2 is designed to be sound-insulating.

[0083] The Figures 14 to 16 In this context, further embodiments are shown with an overlap zone Z extending over a track section 8.

[0084] These further embodiments with overlapping sound-absorbing areas SD have in common that no bridging strip 14 needs to be arranged between the curtain panels 2, 3. The overlap in the overlap zone Z proves to be sufficient to comply with the described requirements.

[0085] In this case, when both curtain panels 2 and 3 are projected onto a common vertical plane, a sound insulation extending completely over the entire height and width is also achieved, which is doubled in the overlap zone Z in this projection.

[0086] As further can be seen from the representations in the Figure 17 and 18 As can be seen, the overlap zone Z can also extend over several consecutive track sections 8, for example over two track sections 8 (see Figure 17 ) or over three or four track sections 8 (compare Figure 18).

[0087] This results in larger overlap heights u or larger overlap zones Z.

[0088] These embodiments are particularly recommended for dividing curtains 1 with six or more panel sections 8, 9 per curtain panel 2, 3 with a height b of the panel sections 8, 9 preferably less than 1.30 m, more preferably about 0.65 m. Figure 18 Figure 1 schematically shows such an embodiment with a height b of 0.65 m.
