Description

field of technology

[0001] The invention relates to a partition curtain for, for example, sports halls, multi-purpose halls, event and exhibition halls, industrial halls or halls, 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, which has a vertical height, is composed of several panel sections which, in the lowered state, extend essentially horizontally, wherein one or more panel sections made of sound-insulating material as well as one or more panel sections made of sound-absorbing material are arranged over the vertical height of each of the curtain panels. State of the art

[0002] Partition curtains of the type in question are known in various designs and for various applications. These serve, for example, to divide large spaces, such as so-called triple-deck sports halls, into several smaller areas, for example, two or three. Known partition curtains, and those according to the invention, can consist of at least two curtain panels that are horizontally spaced apart from one another when lowered, and have inner surfaces facing toward one another and outer surfaces facing away from one another. The curtain panels can be suspended from a curtain support device, which can have one or more winding shafts.

[0003] For example, for physical education classes at schools, as well as for training sessions held by sports clubs that use the halls, good speech intelligibility in the part of a sports hall separated by dividing curtains is essential and indispensable. DIN 18 032 - Halls for gymnastics, games, and multi-purpose use - therefore stipulates that dividing curtains must contribute to sound absorption in these sections. The same DIN standard specifies 22 dB(A) values ​​for the sound insulation of dividing curtains. 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 length of the reverberation times, or the echo effect, within the individual separated sections.

[0004] 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.

[0005] For example, EP 1174 063 B1 discloses partition curtains of the type in question, with wall panels made of fleece-coated covering material, which can achieve a sound absorption coefficient of approximately 0.15. Such partition curtains meet the sound absorption requirements of DIN 18032 Part 4, although the achievable absorption value is not always suitable for ensuring the reverberation times specified in DIN 18041 in sports halls.

[0006] Also known are double-skin 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 wall surface of perforated material. By using a suitably 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 perforated 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 consequences for the reverberation times in the corresponding hall area.

[0007] 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 interior wall panels ensure sound insulation of 22 dB(A) or more, while two exterior perforated wall panels made of, for example, fleece-coated covering material simultaneously provide sound absorption of 0.5 and more. Reverberation times according to DIN 18041 can be achieved with this design. However, it has the disadvantage that such a design is more expensive and more complex to manufacture than conventional partition curtains and that, with a width of at least 0.40 m, the designs require larger installation widths in the hall ceiling area. Replacing partition curtains in existing halls is often associated with considerable effort.

[0008] EP 3 372 743 A1 discloses a partition curtain in which a pair of opposing panel sections is each configured with identical specific acoustic properties. EP 3 416 161 A1 discloses a partition curtain in which panel sections that are predominantly sound-absorbing are located opposite a panel section that is predominantly sound-insulating. Across the vertical height, an equal length of insulating material and sound-absorbing material is provided.

[0009] From EP 3 739 161 A1 a partition curtain is known in which the sound-insulating web sections of one side of the partition curtain are connected to the sound-insulating web sections of the other side of the partition curtain by means of only one sound-insulating bridging strip, with an overall larger surface area of ​​sound-insulating material than of sound-absorbing material. Summary of the invention

[0010] Based on the prior art according to EP 3 739161 A1, the object of the invention is to provide a partition curtain of the type mentioned, which is advantageously designed taking into account the above-described requirements with regard to sound insulation and sound absorption.

[0011] This object is achieved in the subject matter of claim 1, wherein the combined heights of the track sections made of sound-absorbing material of both curtain tracks exceed the vertical height of the separation priority in the lowered state due to an overlapping arrangement of track sections made of sound-absorbing material, thereby resulting in an overlapping region, and wherein a sound-insulating region is formed in the overlapping region.

[0012] The partition curtain is constructed with a large surface area of ​​sound-absorbing material. The required acoustic values, particularly the sound insulation values ​​and reverberation time, can be easily achieved. The sound-absorbing zone extends across the vertical height behind the respective sound-absorbing panel section, across the width of the partition curtain. A sound-absorbing zone can be provided that extends vertically, at least essentially, free from and unconnected to the sound-absorbing panel sections in a horizontal space between these sound-absorbing panel sections.

[0013] The sound-absorbing material can extend essentially alternately in the area of ​​both curtain panels, particularly when the partition curtain is lowered, optionally crossing the gap between the curtain panels by designing it as a bridging strip made of sound-absorbing material, as described in further detail below. This can further result in an overall continuous, preferably uninterrupted, panel of sound-absorbing material, wherein the continuity can be achieved with respect to a projection of the panel sections made of sound-absorbing material of both curtain panels and, optionally, of the aforementioned area or the bridging strip(s) in the horizontal direction onto a common vertical plane.If a bridging strip is arranged, such continuity can also be achieved with regard to a vertical projection of these sound-insulating material sections into a horizontal plane.

[0014] Each curtain track is composed of several horizontally extending track sections arranged one above the other, which can have a width of approximately 0.5 to 1.5 m when viewed in the vertical direction of the curtain track. With respect to the vertical extent of two adjacent curtain tracks, a curtain track can have two sections made of sound-insulating and sound-absorbing material when lowered. Thus, according to a preferred embodiment, all track sections of a curtain track made of sound-insulating material can be arranged directly next to one another when viewed vertically, just as the track sections made of sound-absorbing material can be arranged directly one behind the other in the vertical direction.

[0015] In the case of a curtain track consisting of an even number of track sections, an unequal number of track sections made of sound-insulating and sound-absorbing material can be provided, so that an overall distribution with a larger proportion of sound-absorbing than sound-insulating track sections per curtain track can result.

[0016] At the connections of the web sections alternating between the sound-absorbing web sections and the sound-insulating web sections, the area of ​​sound-insulating material can be provided between two opposing web sections consisting of sound-absorbing material, in the space thereby created.

[0017] In particular, the area of ​​sound-insulating material that runs vertically between two sections of sound-absorbing material, or possibly the bridging strip, can be made of a comparatively stiff material, such as a PVC sheet.

[0018] This creates a sound-insulating, continuous wall surface with a high sound absorption capacity. The alternating extension across both wall surfaces also applies to the sound-absorbing halves of the partition curtain, but without a sound-absorbing connection, such as a bridging strip, across the width or depth of the partition curtain.

[0019] Both curtain panels with an odd number of panels and even number of panels can be arranged in overlapping sections of sound-absorbing material. In these cases, the sound-absorbing area of ​​each panel on a wall surface can have one or more panels more than the sound-insulating area. However, depending on the exterior surface, the size of the sound-absorbing area can vary. When installing two partition curtains, the larger area consisting of sound-absorbing panels is preferably arranged toward the central hall area bordered on two sides by partition curtains.

[0020] The above-mentioned values ​​for sound insulation and sound absorption can be achieved by overlapping the sound-absorbing areas on each side of the partition curtain.

[0021] According to one possible embodiment, the sound-insulating area can be acoustically connected to a wall section made of sound-absorbing material. This acoustic connection ensures that sound passing through the sound-absorbing material of a panel section is also attenuated. For this purpose, an acoustic connection at least at a vertically upper and a vertically lower end of the sound-insulating area with the panel section(s) made of sound-absorbing material is advantageous.

[0022] The acoustic connection can be achieved simply by the sound-insulating area being pressed against the sound-absorbing material. This connection can be achieved or supported by an adhesive design, such as a hook-and-loop fastener. A permanent connection, such as stitching, can also be implemented.

[0023] The acoustic connection provides the desired vertically continuous sound-insulating design, alternating from one side of the partition curtain to the other.

[0024] Furthermore, the sound-insulating area can be designed as a bridging strip made of sound-insulating material. The bridging strip extends from one curtain panel to the other.

[0025] It is further preferred that the bridging strip, in the lowered state, extends at an acute angle to a horizontal line in a vertical cross-section through the partition curtain, in which only one thickness of the web sections is reflected. This creates, as it were, an additional central web section made of sound-absorbing material in the overlapping area.

[0026] The bridging strip can, if it is connected to a vertically upper end of the web section made of sound-absorbing material on one side and a vertically lower end of the web section made of sound-absorbing material on the other side, form a further, central web section which in itself has a greater vertical length than the two web sections made of sound-absorbing material between which it extends.

[0027] In any case, when the partition curtain is lowered, the bridging strip can extend over a significant area at the aforementioned acute angle. Considering the possible connections with the sound-absorbing material strips, a beginning and end section of the bridging strip can also deviate from this.

[0028] The bridging strip can be designed to be unconnected to one of the track sections. It can simply be adjacent to one of the track sections or be attached, for example, by a Velcro fastener as mentioned above.

[0029] It is further preferably provided that the web sections of the partition curtain as a whole, with the possible exception of an uppermost and a lowermost web section on each side, have horizontally opposite connecting seams.

[0030] It is preferably provided that the bridging strip, starting from a first connecting seam between a first and a second wall section on one side of the partition curtain, is connected to a third connecting seam between a third and a fourth web section on the other side of the partition curtain, wherein the first and the third connecting seam are formed offset in the vertical direction to a second connecting seam, which is also located on the side of the third connecting seam, wherein, more preferably and as a rule, the second connecting seam is opposite the first connecting seam.

[0031] A connecting seam extends essentially horizontally and toward an opposing curtain panel. This can result in a (vertical) overlap of panel sections in the area of ​​the overlapping edge strips. In the area of ​​such an overlap, the panel sections can be connected, for example, in the form of a seam. A connection can also be made, for example, by riveting, welding, or screwing, and optionally using a profile, for example, to form a piping connection. Connections using zippers or similar fasteners are also possible in this regard.

[0032] Such an overlapping connecting seam can, moreover, be present both in the case of a connection between adjacent web sections made of sound-insulating and sound-absorbing material and in the case of adjacent web sections which both consist of sound-insulating or sound-absorbing material.

[0033] Furthermore, when the partition curtain is lowered, a bridging strip can extend vertically at least along one or both edges of the curtain, overlapping a connecting seam or overlapping edge areas of the panel sections. This vertical overlap allows the aforementioned continuity of the sound-insulating layer to be achieved in both a horizontal and a vertical projection.

[0034] Opposite track sections can be connected by horizontal traction devices.

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

[0036] In a preferred embodiment, the horizontal traction means extends, in the lowered state of the partition curtain, on top of the superimposed 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, as is also preferred, from the same material, with a track section made of sound-absorbing material from a curtain track. The track section made of sound-absorbing material from a curtain track is extended on the inside of the wall beyond the area of ​​the edge strip used to connect the track sections, toward the inside of the opposite curtain track. This extended section forms the bridging strip, the free end section of which, as described above, can be arranged to overlap the edge strips of two track sections of the opposite curtain track.

[0038] The freely overlapping end section of such a bridging strip, formed in one piece with a track section, can rest on the edge strips of the opposite curtain track or lie beneath the edge strips of the opposite curtain track. In principle, the freely overlapping end section can be aligned with the edge strips of several track elements. This then generally requires additional, conventional horizontal tensioning devices.

[0039] The aforementioned hook-and-loop connection can consist of a substantially hooked area on one of the connecting partners and a substantially looped area on the other connecting partner. Accordingly, at least one end area of ​​the sound-insulating area or the bridging strip can be designed as a hooked or looped area, and a corresponding surface area of ​​the connecting seam can be designed as a looped or hooked area.

[0040] In a further embodiment, this free end area can be connected to the edge strips of the opposite curtain panel, for example by sewing.

[0041] Furthermore, vertical traction devices can be provided.

[0042] A vertical traction means can extend through the bridging strip. Preferably, an opening is formed in the bridging strip that also allows relative movement between the traction means and the bridging strip.

[0043] Furthermore, it can be provided that the bridging strip extends from a web section of a first curtain web to a connecting seam between two edge strips of the web sections of the second curtain web, ends on or below the edge strips of the respective curtain web and is connected to the edge strips of the respective curtain web.

[0044] A partition curtain is specified, preferably with a double-shell construction, i.e., with two curtain panels, with a width between the curtain panels of preferably 200 to 400 mm, more preferably approximately 250 to 300 mm. This width essentially corresponds to known designs. At the same time, such a partition curtain meets both the requirements of DIN 18032 Part 4, namely the 22 dB(A) sound insulation and the simultaneous sound absorption requirements.

[0045] A sound absorption value of 0.5 or more is achievable. This level of sound absorption 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.

Description of the embodiments

[0047] Shown and described is, firstly, with reference to Figure 1 , a partition curtain 1, such as this one in halls, especially sports halls H (see, for example, schematic representation in Figure 2) or similar areas. This allows areas 17 of Hall H or similar to be separated and, to a large extent, prevents noise from being transmitted from one side of the hall to the other.

[0048] The partition curtain 1 essentially consists of two curtain panels 2 and 3, which can be described as wall surfaces, whereby the partition curtain 1 in the lowered state, as is the case for example in Figure 1 shown, extends essentially vertically.

[0049] The curtain tracks 2, 3 can be connected via horizontal tensioning means 4 in the form of cross connectors, which are fastened in the area of ​​the inner surfaces of the curtain tracks 2 and 3 (see also the Figures 3 to 5 ).

[0050] How to continue in Figure 1As shown schematically, a gathering rail 5 can be provided in the area of ​​the end facing the hall floor when the partition curtain 1 is lowered. In a preferred embodiment, such a gathering rail 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 Figures 7 to 11 ) and acts primarily on the underside of the connecting area between curtain panels 2 and 3.

[0051] The gathering rail 5 is attached to one or more vertical tensioning means 6 in the form of a gathering cord. When lowered, the vertical tensioning means 6 extend through the partition curtain 1 approximately centrally between the curtain panels 2 and 3. Furthermore, the vertical tensioning means 6 can be attached at the end, i.e., at the ceiling, to a winding shaft 7, preferably driven by a motor, in particular an electric motor, or deflected to a winding device in the area of ​​the motor.

[0052] The motorized device can be used to act on the connecting means or traction means, such as in particular the vertical traction means 6. Thus, the partition curtain 1 can be pulled upwards under a hall ceiling while gathering the curtain panels 2 and 3 (see Figure 6 ) or from here towards the hall floor.

[0053] Figure 6, which depicts the gathered state, is a schematic representation. The horizontal and vertical tensioning elements, as well as the bridging strip, have obviously been omitted.

[0054] The curtain tracks 2 and 3 are in transverse to the vertical extension and thus in the previously described longitudinal extension of the partition curtain 1 running track sections 8 and 9 of a curtain track 2, 3, see Figures 7 to 11 , are divided. 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, particularly in the lowered position.

[0055] The panel sections 8 and 9 of a curtain panel 2 and 3, respectively, which extend essentially horizontally when the partition curtain 1 is lowered, viewed from the broad side surface of a curtain panel 2, 3, can be connected to one another via connecting seams 12, 12a, 12b, 12c formed in the region of superimposed edge strips 10, 11 of panel sections 8 and 9. The horizontal tension means 4 can then also be attached to the panel sections 8 and 9 in the region of these edge strips 10, 11.

[0056] The fastening of the horizontal tension means 4 to the edge strips 10, 11, preferably in the area of ​​the connecting seams, can be achieved by sewing, gluing, stapling, welding, screwing or riveting.

[0057] In a further embodiment, although not shown, the track sections 8 and 9 can also be riveted, screwed, clamped, pressed or glued if profiles or strips are arranged.

[0058] The partition curtain 1 or the curtain panels 2, 3 are preferably attached to a hall ceiling via support devices 13. The horizontal distance between the support devices 13, considered in the use state, essentially determines the width a of the partition curtain 1 in the ceiling area, as well as preferably the width in the floor-side end area of ​​the partition curtain 1, which essentially corresponds to this width a. The width a of the partition curtain 1 can be approximately 0.2 to 0.4 m, further approximately 0.3 to 0.35 m.

[0059] According to the illustrated embodiments, regions SD with track sections 8 made of sound-insulating material and regions SB with track sections 9 made of sound-absorbing material can be arranged across the vertical height c of each curtain track 2, 3. The sound-insulating material for forming the track sections 8 in particular can be, for example, artificial leather, plastic film, fleece, or even textile fabric. The material for the sound-absorbing track sections 9 can, as is also preferred, be perforated or punched.

[0060] As can be seen from the illustrations, the curtain tracks 2 and 3 can each have a continuous sound-insulating area SD consisting of several track sections 8 arranged one above the other, as well as a continuous sound-absorbing area SB consisting of track sections 9 arranged directly one above the other in the vertical direction.

[0061] When the partition curtain 1 is lowered, a sound-insulating area SD of one curtain track 2 or 3 can be opposite a sound-absorbing area SB of the other curtain track 3 or 2.

[0062] Thus, according to the Figure 7 In the illustrated embodiment, the curtain tracks 2 and 3, with a linear number of track sections 8 and 9 per curtain track 2, 3, can be provided with a sound-insulating region SD and a sound-absorbing region SB with respect to their vertical extension. In the illustrated embodiment, a sound-insulating region SD of a curtain track 2 or 3 extends, starting from the top, over three track sections 8, and a sound-absorbing region SB over a further three track sections 9.

[0063] Opposite the sound-insulating area SD of the curtain track 2 is a sound-absorbing area SB of the other curtain track 3 of the same partition curtain 1, but this overlaps with the sound-absorbing area SB of the curtain track 2.

[0064] Between the overlapping track sections 9, which consist of sound-absorbing material, there is an area, here specifically designed as a bridging strip 14, which can be seen in the cross-sectional view of the Figures 7-11 extends obliquely to a horizontal HO.

[0065] In the cross-sectional view, the area or bridging strip 14 essentially forms an acute angle α with the horizontal HO.

[0066] The angle α can in particular be between 25 and 80°.

[0067] The region or overlapping section 14 can, as in the illustrated embodiments, be connected from a first connecting seam 12a between a first and a second web section 8a, 9a to a third connecting seam 12b, which is vertically offset from a second connecting seam 12c, which is opposite the first connecting seam 12a. In this case, and preferably, the bridging strip 14 is arranged in the space between the curtain webs 2, 3, extending between vertically offset connecting seams.

[0068] The bridging strip 14 can also be connected to a horizontal traction means 4 at an end region where it is connected to a connecting seam.

[0069] The bridging strip 14 can also be penetrated by a vertical traction means 6.

[0070] In the design of the Figure 8, in which each curtain panel is formed with six panel sections 8 and 9 arranged one below the other, the bridging strip 14 is formed extending from a lower end of the second panel section 8 as seen from above, so that on the left side of this partition curtain 1 in the drawing, a total of four panel sections made of sound-absorbing material are arranged one below the other, following two panel sections 9 made of sound-insulating material. Opposite, with the overlap in the area of ​​the bridging section 14, three panel sections 9 made of sound-absorbing material are arranged one below the other, followed by three panel sections 9 made of sound-insulating material.

[0071] In the design of the Figure 9, in which each curtain panel is also formed with six panel sections 8 and 9 arranged one below the other, the bridging strip 14 is formed extending from a lower end of the fourth panel section 8 as seen from above, so that on the left side of this partition curtain 1 in the drawing, a total of four panel sections made of sound-insulating material are arranged one below the other, followed by two panel sections 9 made of sound-absorbing material. Opposite, with the overlap in the area of ​​the partition section 14, five panel sections 9 made of sound-absorbing material are arranged one below the other, followed by only one panel section 8 made of sound-insulating material.

[0072] In the design of the Figure 10, in which each curtain panel is formed with five panel sections 8 and 9 arranged one below the other, the bridging strip 14 is formed extending from a lower end of the third panel section 8 as seen from above, so that on the left side of this partition curtain 1 in the drawing, a total of three panel sections made of sound-absorbing material are arranged one below the other. Opposite, with the overlap in the area of ​​the partition section 14, four panel sections 9 made of sound-absorbing material are arranged one below the other, followed by only one panel section 9 made of sound-absorbing material.

[0073] In the design of the Figure 11, in which each curtain panel is also formed with five panel sections 8 and 9 arranged one below the other, the bridging strip 14 is formed extending from a lower end of the second panel section 8 as seen from above, so that on the left side of this partition curtain 1 in the drawing, a total of two panel sections made of sound-insulating material are arranged one below the other, followed by three panel sections 9 made of sound-absorbing material. Opposite, with the overlap in the area of ​​the bridging section 14, three panel sections 9 made of sound-absorbing material are arranged one below the other, followed by two panel sections made of sound-insulating material.

[0074] With reference to the Figures 12 to 14possible connections of the bridging strip 14, or the area, with an opposite curtain track, in particular in the area of ​​a connecting seam, are explained in more detail with reference to the connection by an adhesive connection, in particular a Velcro connection, which is also stated as possible.

[0075] An end region 15 of the region or of the bridging section 14 can be provided on the underside with a hook formation 16, wherein the connecting seam can suitably be provided on the upper side with a loop formation 17.

[0076] The hook formation 16 and / or the loop formation 17 can be applied to the respective area of ​​the bridging strip (area) or the connecting seam by means of a separate layer, in particular a textile layer (plastic designs in this regard are also known, which are also included in the disclosure). The bridging strip (area) and / or the connecting seam can also be designed directly in this way (for example, by selecting a suitable textile). In this case, the bridging strip (area) and / or the web section forming the connecting seam can be designed in this way over an entire vertical length and on one or both sides. This also applies to the other embodiments.

[0077] Furthermore, and this also applies to the other embodiments, the arrangement of the hook formation 16 and the loop formation 17 can also be provided in reverse.

[0078] For all relevant designs, it also applies that the pairing does not have to be strictly differentiated between hooks and loops. There are also hook designs on both sides that (already) provide the desired adhesion in this context. The same applies to loop designs.

[0079] In Figure 13 is a comparable design according to Figure 12 reproduced, only that here the respective design with regard to a Velcro connection is formed on the underside of the connecting seam or the upper side of the bridging strip (area).

[0080] In Figure 14 an embodiment for the bridging strip is shown, which can also be valid for a track section forming a respective connecting section - alternatively or in combination - in which the respective design for the adhesive / Velcro connection is formed on both sides of the bridging strip.
