Definitions

  • the invention relates to a pull-up curtain according to the features of the preamble of claim 1.
  • Partition curtains of the type in question are used, 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 panels that are horizontally spaced apart when lowered and have inner surfaces facing one another and outer surfaces that repel one another.
  • the curtain panels are attached to a curtain support device with a winding shaft, whereby the curtain support device can also have two or more winding shafts.
  • Partition curtains of the type in question are known, in this case with wall surfaces made of fleece-coated covering material, with which a sound absorption coefficient of approximately 0.15 can be achieved on partition curtains.
  • partition curtains meet the requirements of DIN18032-4 for sound absorption, although the achievable absorption value is not always suitable for ensuring the reverberation times according to DIN18041 in sports halls.
  • Double-shell partition curtains are also known, with or without an additional textile insert, in which one wall surface is made of sound-absorbing material and the opposite one is made of perforated material. If a correspondingly heavy covering material is used for the sound-absorbing wall surface, the 22dB(A) required by DIN18032-4 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 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 22dB (A) or above, while two perforated wall surfaces arranged on the outside, for example made of fleece-coated covering material, simultaneously ensure sound absorption of Offer 0.5 and above. Reverberation times according to DIN18041 can be achieved with this design.
  • the gathered curtain package is usually moved between two panels on the ceiling side.
  • the maximum width of the curtain package is defined by the clear distance between the panels. In this regard, widths between 400 and 500 mm are common.
  • Modern curtain panels that achieve the insulation values described above prove to be bulky in terms of the desired wrinkle formation due to the generally heavy and thick covering material. If the curtain heights are the same, they can be opposite each other.
  • the lighter, less bulky curtain panels that are often installed result in larger widths when gathered up, which does not allow or at least makes it more difficult to replace the existing curtain panels with modern curtain panels that comply with DIN values if the ceiling-side panels are left in place.
  • a partition curtain is known in which the folding zone in a curtain panel is formed by two separate intermediate layers with an inner and an outer continuous layer or, alternatively, by a continuous outer layer and two separate layers which correspond to the intermediate layers mentioned but not from an inner one location are covered.
  • a partition curtain is known without a folding zone.
  • the same is also from the FR 2 769 944 A1 known, in which a partition curtain is folded between two rows of traction means that follow one another in the vertical direction, but no reduction in thickness or partial curtain panels are formed for this purpose.
  • one object of the invention is to advantageously design a partition curtain of the type in question.
  • the folding zone is given by a reduction in thickness, and if necessary compression, of the curtain panel, which is otherwise formed throughout using the same material, or the curtain panel has partial curtain panels, the associated edge edges of which are in the area between two Directly successive rows of horizontal traction means run in the vertical direction based on the lowered state and are used to form the fold zone, which is formed by a fold layer connecting the edge edges.
  • the folding zone is achieved by reducing the thickness and, if necessary, compacting the curtain sheet, which is otherwise made of uniform material throughout.
  • the uniform material continuity initially and essentially refers to an area of the curtain track between two rows of horizontal traction devices that follow one another in the vertical direction.
  • the reduction in thickness can be achieved, for example, by a corresponding thinning of the material of the curtain panel in this area, for example as a result of the action of a rolling device in the course of producing the curtain panel.
  • the reduction in thickness to form the fold zone in the state of use can only be on the outside or only on the inside. In this context, a central thinning of the curtain sheet is also possible simply by reducing the thickness, for example as a result of rolling on both sides to achieve the thickness reduction.
  • the thickness reduction in a one-piece design can also be achieved by one seam or several seams (darts).
  • the folding zone is provided in that the curtain panel has partial curtain panels, the associated edge edges of which run in the area between two rows of horizontal traction means that follow one another in the vertical direction in relation to the lowered state and are used to form the folding zone.
  • the curtain panel has partial curtain panels, the associated edge edges of which run in the area between two rows of horizontal traction means that follow one another in the vertical direction in relation to the lowered state and are used to form the folding zone.
  • there are correspondingly on both sides of the folding zone If necessary, separately manufactured partial curtain panels are provided, which are connected to one another in the area of the folding zone and are provided with a folded layer connecting the edge edges.
  • connection can be a direct connection, for example by sewing, clamping or riveting the edge edges of the curtain sections that face one another.
  • a connection in this regard can also be provided, for example, by a zipper or the like. What is important here is that this connection results in a folding zone, preferably a line-like folding zone.
  • the folded layer is a separate layer compared to the partial curtain panels, which connects the partial curtain panels with one another.
  • the horizontal folding zone represents a targeted disturbance in the course of the material, which leads to a predetermined folding (kinking) around a geometric folding axis that arises based on the formation of the folding zone.
  • the curtain panel is always folded in the same fold areas when it is raised up. This also results in a favorable package arrangement of the gathered curtain panel. Viewed transversely to the longitudinal extent of a curtain panel, there is a reduced package width of the gathered curtain panel compared to a comparable curtain panel without folding zones according to the invention.
  • the web sections on both sides of the folding zone extend in the folded position oriented along a vertical or at a comparatively small acute angle of, for example, 20 degrees or less to the vertical.
  • a partition curtain designed in this way can be designed to meet both requirements of DIN 18032-4, namely that of 22dB(A) sound insulation and that of simultaneous sound absorption, while still being able to be easily gathered.
  • a sound absorption value of 0.5 and more can be achieved. Such a level of sound absorption has proven itself. With an average sound-absorbing design of the other surrounding surfaces, such as ceilings, floors 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 folding zone can be formed approximately vertically in the middle between the successive rows of horizontal traction means.
  • web sections of essentially the same length can result on both sides of the folding zone - with reference to a vertical section through the curtain panel - at the end of which facing away from the folding zone the associated ends of the traction means, which run essentially horizontally in the lowered state of the curtain panel, are connected could be.
  • the folding zone - based on a vertical extent of the curtain panel - can also be formed in a central area between the successive rows of horizontal traction means, which central area can extend over a vertical height of approximately up to 15 or 20 percent, further if necessary up to 50 percent of the vertical height of the curtain panel between successive rows.
  • areas of the surface of the curtain panel that face one another in the gathered state such as, for example, and in particular, inner surfaces of the curtain panel, without any further influence from the outside, for example via a force acting from the outside , have a maximum distance from each other that is less than four times the thickness of the curtain panel outside the folding zone and possibly outside a weakening zone in which the horizontal traction means are connected.
  • the distance in this regard can also be so small immediately after the folding zone that, if necessary, the surfaces facing one another can be in direct contact with one another. In comparison to the known prior art, this results in a more compact folding of the gathered curtain panel with no external influence.
  • the maximum distance between the surfaces facing each other can be 3 or 2 times or less the web thickness in the unaffected area Curtain track, correspondingly outside the folding and weakening zones.
  • the curtain panel can have a surface weight of more than 1,200 g/m 2 outside the folding zone and possibly outside the weakening zone in which the horizontal traction means are connected.
  • the relevant basis weight can be up to 3,000 g/m 2 or more, for example approximately 5,000 or 8,000 g/m 2 .
  • the folded layer can, as is also preferred, enable the curtain panel to be folded along a line-like zone.
  • the folded layer can be strip-like and have a thickness that can correspond to half or less of the thickness of one or both partial curtain panels outside the folding zone and possibly outside the weakening zone in which the horizontal traction means are connected.
  • a folded layer with a thickness can correspond to approximately one hundredth or more, further for example one tenth to one fifth of the partial web thickness, for example 2 to 8 mm, further for example approximately 4 or 5 mm.
  • the folded layer can be glued, sewn, welded and/or connected by a zipper to one or both curtain panels.
  • the folding layer can consist of a textile material, leather, artificial leather, plastic material or the like.
  • the folded layer can optionally be made the same as the partial curtain panels, in particular with regard to the material forming the outer surfaces.
  • a surface can be made of a sound-absorbing and/or sound-damping material towards the outside, towards the room, entirely or in part.
  • one or all curtain panels can be made of a perforated or perforated material.
  • a curtain track is composed of several track segments arranged one above the other in the vertical direction.
  • the longitudinal edge edges of the web segments facing each other are connected to one another and form weakening zones in this area, on which the rows of horizontal traction devices attack and are attached there accordingly.
  • a web segment can have two partial curtain webs, which in turn, as described, are connected to one another along their facing longitudinal edges to form the fold zone.
  • the web segments can be connected to one another, for example by sewing, gluing, welding or alternatively by means of a zipper or a piping connection.
  • the arrangement of the folded layer can, as is also preferred, be arranged on the inside with respect to the position of use of the curtain panel, in this case possibly overlapping the inside of both partial curtain panels.
  • the folded position can continue in the lowered state of the curtain track at least partially exposed in a gap-like manner towards the outside, ie directed towards the outside of the curtain track, for example over a vertical gap extent of a few millimeters, for example 1, 2 or 3 mm up to 5 or 10 mm or more.
  • the folding zone is essentially integrated in the vertical extent of the curtain panel.
  • the ranges or value ranges or multiple ranges specified above and below also include all intermediate values, in particular in 1/10 increments of the respective dimension, and if necessary also dimensionless.
  • the statement of up to 1,200 g/m 2 or more also includes the disclosure of up to 1,199.9 g/m 2 or more, up to 1,075.4 g/m 2 , the disclosure of half or less also includes the disclosure of 0.4 or less, 0.2 or less.
  • this disclosure can serve to delimit a specified range boundary from below and/or above, but alternatively or additionally it can serve to disclose one or more singular values from a respective specified range.
  • a dividing curtain 1 as can be used, for example, in halls, especially sports halls or similar areas. This allows areas of the hall or the like to be separated and largely prevents noise from being transmitted from one side of the hall area to the other.
  • the dividing curtain 1 essentially consists of two curtain panels 2 and 3, which can be referred to as wall surfaces, with the dividing curtain 1 in the lowered state, as shown, for example, in Figure 1 is shown, extends essentially vertically.

  • a ruffle rail 5 can be provided in the area of the end facing the hall floor when the partition curtain 1 is lowered.
  • a ruffle 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 Figure 2 ) and preferably acts on the underside of the connection area between the curtain panels 2 and 3.

  • the track segments 9 of a curtain track 2 or 3, which extend essentially horizontally when the partition curtain 1 is lowered, are connected to one another, for example via seams 10.
  • the horizontal traction means 4 can then also be fastened on the inside surface.
