Definitions

  • the invention relates to a combinraffbaren curtain for sports halls, multi-purpose halls, event and exhibition halls, industrial halls, halls or the like, arranged with at least one curtain-carrying device and at least two oppositely arranged on this, possibly multi-layered curtain tracks made of synthetic leather, plastic film, nonwoven, textile fabric or and the like, which curtain webs are connected to substantially horizontally extending traction means, and in cooperation with vertically extending traction means to the common Matterraffen to the curtain support means, wherein relative to a lowered state, a plurality of vertically spaced rows of equal vertical height of juxtaposed horizontal traction means are provided.
  • Curtains of the type in question are used, for example, the separation of large areas, such as so-called 3-compartment sports halls in several, for example, two or three areas smaller areas.
  • Known curtains consist of at least two in the discharged state horizontally spaced-apart curtain tracks, which have mutually facing inner surfaces and mutually repellent outer surfaces.
  • the curtain tracks are attached to a curtain support having a take-up shaft, and the curtain support may also have two or more take-up shafts.
  • the DIN18032 - halls for gymnastics, games and multi-purpose use - therefore requires that curtains have to contribute to the sound absorption of the hall parts.
  • the same DIN stipulates 22dB (A) values.
  • the acoustical conditions in a sports hall are, in addition to the sound insulation between the hall parts separated by separating curtains, influenced considerably by the duration of the reverberation times or the echo effect within the individual separated hall parts.
  • the EP 3 225 774 A1 and EP 2 947 256 B1 refer to three- or four-shell curtains, each one or two internally arranged panels ensure the sound insulation of 22dB (A) or above, two externally arranged perforated wall surfaces, for example, fleece-coated covering material simultaneously offer a sound absorption of 0.5 and above. Reverberation times in accordance with DIN18041 can be achieved with this construction.
  • curtain curtains results in a snatching the curtain tracks due to the inherent usually stiffness of the web material in a between two vertically immediately successive rows of horizontally extending traction means resulting curtain track area of a relatively large curvature. Due to the given stiffness of the curtain track, the surfaces of the shirred curtain track facing one another on both sides of this curvature in the raised state are spaced relatively far from each other, in particular in a connecting section immediately following the curvature. This distance may be 30 to 50 times or more the unaffected thickness of the curtain web. The distance can be comparatively large, in particular in the case of a material which is highly sound-absorbing, since this material generally also has a high basis weight and high rigidity. This then resulting distance can affect a high-usability or no longer make sense feasible. So there is the problem, in spite of, as desired, highly sound-absorbing material for a curtain track still reach a required high-clearance.
  • the shirred curtain package is usually driven on the ceiling side between two panels.
  • the maximum width of the curtain package is defined by the clearance between the panels. In this regard, widths between 400 and 500 mm are common.
  • Modern curtain tracks that achieve the above-described insulation values prove bulky with respect to the desired wrinkling due to the usually heavy and thick fabric.
  • At the same curtain heights can be compared to the often built lighter, less bulky curtain tracks larger widths in the ragged state result, which does not allow replacement of existing curtain tracks against modern, the DIN values corresponding curtain tracks when leaving the ceiling side panels or at least difficult.
  • a possible solution of the problem is given by a separating curtain in which a horizontally extending folding zone is formed in a curtain web in the lowered state between two vertically successive rows, in order to predefine the curtain web in the course a high-flyer.
  • the horizontally running folding zone represents a deliberate disturbance in the material flow leading to a predetermined wrinkles (buckling) leads to a due to the formation of the folding zone adjusting geometric folding axis.
  • a ratcheting in a region between two consecutively in the vertical direction immediately following rows of horizontal traction means low or especially in the below-explained preferred embodiment with vertically central formation of the folding zone practically no large curvature sections with large radii of curvature, in particular radii of curvature a multiple, for example 30 to 50 times or more, the material thickness of the curtain web outside the folding zone correspond.
  • Such a designed curtain can be designed to meet both requirements of DIN18032-4, namely after 22dB (A) sound insulation and after simultaneous sound absorption, while still good high-grip.
  • a sound absorption value of 0.5 and more can be achieved.
  • Such a degree of sound absorption has proven itself.
  • reverberation times below 2 seconds can be achieved.
  • the folding zone may be formed approximately vertically in the middle between the successive rows of horizontal pulling means.
  • the folding zone - based on a vertical extension of the curtain web - be formed in a central region between the successive rows of horizontal traction means, which central region may extend over a vertical height, up to about 15 or 20 percent, further optionally to 50% of the vertical height of the curtain web between successive rows.
  • the result is preferably a line-like folding zone, wherein the line, as further preferred, parallel to a longitudinal axis of the curtain support means and / or parallel to a winding axis of the curtain support device.
  • the folding between immediately vertically successive rows of horizontal traction means located and in the raised state facing each other areas of the surface of the curtain web, for example, as well as in particular, inner surfaces of the curtain web, without further interference from the outside, for example via an externally applied force have a maximum distance to each other which is less than four times a thickness of the curtain web outside the folding zone and optionally outside a weakening zone in which the horizontal traction means are connected.
  • the distance in this regard may also be so small immediately after the folding zone that, if appropriate, a direct contact of the surface facing each other may be present to each other. This results in comparison to the known state of the art with a corresponding non-interference from the outside a more compact folding of the rickety curtain web.
  • the maximum distance of the surfaces facing each other may correspond to 3 or 2 times or less of the web thickness in the uninfluenced area of the curtain web, corresponding to outside the folding and weakening zones.
  • the curtain web may have a basis weight of more than 1,200 g / m 2 outside the folding zone and optionally outside the weakening zone in which the horizontal traction means are connected.
  • the basis weight thereof may be up to 3,000 g / m 2 or more, such as about 5,000 or 8,000 g / m 2 or more.
  • the folding zone can be given by a reduction in thickness, and optionally compression, which, moreover, is formed throughout the continuous curtain web formed in the same material.
  • the uniformity of material uniformity initially and essentially relates to a region of the curtain web between two successive rows of horizontal traction means in the vertical direction.
  • the reduction in thickness may, for example, be given by a corresponding thinning of the material of the curtain web in this area, for example due to action via a rolling device during the production of the curtain web.
  • the thickness reduction for forming the folding zone in the use state can be given solely on the outside or alone on the inside. Also, a central dilution of the curtain web is possible in this context solely by a reduction in thickness, for example, according to a two-sided rolling action to achieve the thickness reduction.
  • the thickness reduction in one-piece design can also be given by a seam or several seams (darts).
