Definitions

  • the invention 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 and one , a vertical height curtain track is composed of several track sections that extend essentially horizontally in the lowered state, with one or more track sections made of sound-absorbing material as well as one or more track sections made of sound-absorbing material being arranged over the vertical height of each of the curtain tracks.
  • the invention further 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 which extend 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 of sound-absorbing material of both curtain tracks in a width direction of the partition curtain with one another are connected by means of a bridging strip made of sound-absorbing material.
  • 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 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.
  • 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.
  • partition curtains meet the requirements of DIN18032 Part 4 for sound absorption, whereby the achievable absorption value is not always suitable for ensuring the reverberation times according to DIN18041 in sports halls.
  • 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-insulating 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 sometimes 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-insulating 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 interior wall surfaces ensure sound insulation of 22 dB (A) or more, two perforated wall surfaces arranged on the outside, for example made of fleece-coated covering material, simultaneously offer sound absorption of 0.5 and more .
  • Reverberation times according to DIN18041 are with this construction reachable.
  • there is the disadvantage that such a construction is more expensive and technically more complex than conventional partition curtains and that the constructions require greater installation widths in the area of the hall ceiling with a width of at least 0.40 m. In the case of the renewal of partition curtains in existing halls, this is often associated with great effort.
  • one object of the invention is to further improve a partition curtain of the type in question, taking into account the above-described requirements with regard to sound insulation and sound absorption.
  • a possible solution to the problem is given according to a first inventive idea with a partition curtain, which is based on the fact that the combined vertical heights of the track sections made of sound-absorbing material of both curtain tracks exceed the vertical height of the partition curtain in the lowered state, due to an overlapping arrangement of the track sections sound-absorbing material of the curtain sheets.
  • the bridging strip starting from a track section of a first curtain track, extends to a connecting seam between two edge strips of the track sections of the second curtain track, ends on or under the edge strips of the respective curtain track and is connected to the edge strips of the respective curtain track .
  • a partition curtain is specified, which is preferably constructed with two shells, with a width between the curtain strips of preferably 200 to 400 mm, more preferably about 250 to 300 mm.
  • a width essentially corresponds to the known constructions.
  • 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 areas, 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.
  • an overall continuous, preferably uninterrupted path of sound-absorbing material can result, the continuity being determined with reference to FIG a projection of the track sections made of sound-absorbing material of both curtain tracks and possibly the bridging strips in the horizontal direction onto a common vertical plane can result.
  • 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 web is composed of several horizontally extending web sections arranged one above the other, which web sections, viewed in the vertical direction of the curtain web, can have a width of approximately 0.5 to 1.5 m.
  • a curtain web can have two areas made of sound-absorbing and sound-absorbing material with respect to the vertical extension in the lowered state.
  • 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.
  • an equal number of track sections made of sound-absorbing and sound-absorbing material can be provided, so that a total of half a division per curtain track can result.
  • 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.
  • the lower edge can be seen in the middle of the partition curtain wall surfaces, viewed in the vertical direction the sound-absorbing half arranged on one side of the partition curtain in the upper area can be arranged essentially in the same horizontal plane as the upper edge of the opposite sound-absorbing wall surface, which is accordingly arranged in the lower area.
  • the bridging strip made of sound-absorbing material which extends essentially horizontally when the partition curtain is lowered, can be provided.
  • the bridging strip as proposed, 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 connected to the edge edges of the sound-absorbing web sections of both curtain webs, in particular sewn.
  • a 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 act as a horizontal traction means take.
  • the additional arrangement of a, for example, rope-shaped horizontal traction means, as is usually provided, can be omitted 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 one directly connected to one another by the two Track sections of the curtain track given edge strips.
  • 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. Then the facing end of the bridging strip is placed on the edge strip package or under the edge strip package and also connected to it.
  • 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 can take place in one process, for example a sewing process.
  • the bridging strips can consist of a comparatively stiff material such as a PVC sheet.
  • a sound-absorbing, continuous wall surface which according to the invention extends, for example, half alternately over 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.
  • an overlapping arrangement of the web sections made of sound-absorbing material of the curtain webs can be provided.
  • either the sound-absorbing area of a wall surface or the sound-absorbing area can have one or more track sections more. This arrangement is reversed for the opposite curtain track.
  • the larger area consisting of sound-absorbing web sections is preferred when installing two partition curtains to the middle of the hall area, delimited on two sides by curtains.
  • the stated values for sound insulation and sound absorption can be achieved in that the sound-insulating areas on each side of the partition curtain overlap in the area of two or more sound-insulating web sections.
  • An arrangement of a bridging strip made of sound-absorbing material between the sound-absorbing areas of both curtain lengths can be dispensed with.
  • 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 three-tier sports halls.
  • the area of the vertical overlap can be increased or decreased, preferably with the arrangement of track sections with a vertical width of less than 1.30 meters.
  • 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.
  • these sound-absorbing web sections are preferably perforated preferably with a micro-perforation, and if necessary, can be backed with an additional insert in the area between the curtain strips.
  • 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.
  • the track sections of both curtain tracks can be connected to one another via a rope-like structure when the partition curtain is in the lowered state be connected substantially horizontally extending traction means.
  • 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 even riveting.
  • the bridging strip only, i. exclusively connected to the horizontal traction mechanism.
  • 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 superimposed edge strips which extends essentially horizontally and towards an opposite curtain web. There may be an overlap of web section areas in the area of the superposed edge strips. In the area of such an overlap, the web sections can be connected, 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.
  • a bridging strip can also run in the lowered state of the partition curtain at least at the edge 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.
  • This vertical overlap allows the previously described continuity of the sound-absorbing layer to be achieved both in a horizontal projection and in a vertical projection.

  • the bridging section can also be made in one piece, in addition, if necessary, and also preferably, of the same material, with a track section made of sound-absorbing material of a curtain track.
  • the 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 so as to overlap the edge strips of two web sections of the opposite curtain web.
