Definitions

  • the invention initially relates to a curtain for sports halls, multi-purpose halls, event halls, industrial halls, halls or the like, wherein the curtain has two outer surfaces, which are formed by each having a surface extension curtain tracks with facing inner surfaces, the curtain tracks of a lowered Condition are aufraffbar in a raised state.
  • the invention further relates to a hall such as a sports hall or the like, wherein the hall can be divided by means of two or more curtains, wherein further the curtains each have two outer surfaces, which are formed by a surface extension having curtain tracks and aufraffbar from a lowered state to a raised state are, in addition, which limit each other in the lowered state curtain tracks of two curtains delimiting a subspace formed thereby the hall.
  • curtains of the type in question are known. These serve, for example, the separation of large areas, such as so-called three-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 may be attached to a curtain carrier, wherein but the curtain support means may also have two or more winding shafts.
  • a second technical solution is from the EP 1174 063 A1 known.
  • One or both panels, or the curtain panels that make up the panels, are coated outwardly with a nonwoven or other sound absorbing material that is firmly bonded to the surface of the curtain panel and is applied for cost reasons in the curtain sheet manufacturing process.
  • This technical solution is intended to achieve both the sound insulation of 22 dB (A) required by DIN and the equally required sound absorption.
  • both the nonwoven web and the initially liquid plastic material pass under high pressure through a number of rollers. Due to this pressure, for example, a 2 mm thick nonwoven web, which is soft, open, porous and thereby sound-absorbing before passing through the rollers, compressed to a thickness of, for example, 1 mm.
  • the surface of the web which was soft, open and porous before passing through the rolls is considerably smoother and more closed after the production process. The sound absorption of the nonwoven web is thereby drastically reduced.
  • the invention initially has the task of specifying a curtain of the type in question, which leads in particular to particularly good sound insulation or sound absorption values.
  • a possible solution to the problem is given according to a first idea of the invention in a curtain in which it is intended that a curtain web with respect to its inner and outer surface in the lowered state in a cross-section perpendicular to the surface extension of a curtain web forms an acute angle with a vertical ,
  • a sound event with certain acoustic characteristics for example played back via loudspeakers, musical instruments or voice
  • this sound event can still be measured and audible even after it has been switched off.
  • This decay of the sound event is referred to as the reverberation time, the period in which the sound pressure level of the sound event drops by 60 dB (reduction to 1/1000) as the reverberation time.
  • the "shutdown" of the original sound event is only to clarify the context. Even continuous sound events are able to stimulate the reverberation in a room.
  • the reverberation time of a room is directly dependent on the volume of the room and the number and characteristics of the sound absorbing surfaces.
  • the reverberation of a room comes about as a result of the fact that the sound at the room boundary surfaces is thrown back again and again.
  • the large number of incoming reflections thus forms the reverberation.
  • the number of reflections and thus the corresponding reverberation time increases.
  • a special case is represented by the so-called flutter echoes, which result when non-absorbent, parallel space-bounding surfaces are present. These Flatterechos lead by multiple reflection with low energy loss at the reverberant reflection surface to longer reverberation times. If the parallelism of the reflection surfaces is canceled out by full or partial obliquity, as proposed according to the invention, this circumstance contributes to the reduction of the reverberation times.
  • Curtains are such perpendicular and rectangular surfaces that provide an ideal condition for the multiple reflection of sound waves, especially in the middle thirds of so-called three-compartment sports halls on both sides by curtains made of synthetic leather, plastic film, fleece, textile fabric o. The like. be limited. However, not only in the middle third, also in the outer hall parts of three-compartment sports halls as well as in all two-compartment sports halls with one-sided Trennvorhang II, the sound from the vertically arranged outer walls is also reflected, which only by consuming sound-absorbing measures on the Exterior walls can be restricted.
  • the curtain track Due to the proposed embodiment of the curtain track this is not as usual in a cross-section elongated straight running arranged, but rather obliquely to a vertical or to a Vertical plane.
  • the sound waves can no longer impinge on a straight path on the opposite surface, possibly arranged in the vertical plane, in order to be reflected from there several times, as explained. Rather, the sound waves are deflected at an angle up or down.
  • the opposite separating curtain also has an areal extension at an acute angle to the vertical with respect to the facing curtain runway, the echo or flutter echo effect arising in the known curtains extending within vertical planes does not come into play or is largely limited.
  • mutually facing curtain tracks both curtains in terms of their inner and outer surfaces in the lowered state in a cross-section perpendicular to the surface extension of a curtain track a sharp first angle with a vertical and at this angle extend to an end region of the respective separation curtain which has a maximum or minimum width, or extend to a turning region in which an outer surface merges into a second vertical angle enclosed acute angle.
  • the inner and outer surfaces of a curtain web extend with respect to a common curtain track section in a preferred embodiment at the same acute angle to a vertical. It is also possible for the inner and outer surfaces of the curtain track to run parallel to each other in this acute-angled region.
  • the inclination of a curtain track can be given, for example, starting from the bottom of the curtain to the ceiling-side suspension area.
  • Such curtains are in the spacing direction of the curtain tracks of a curtain separation between 0.20 and 0.40 m wide. Leaving such a width in the ceiling area, a width of the curtain can result in the bottom area, which is much larger compared to the width in the ceiling area. This can lead to problems with given pitch sizes and floor markings on the hall floor. It may possibly result in a width in the bottom area of 1.50 to 2 m.
  • Such a solution is only partially suitable, as well as a corresponding broadening of the curtain in the ceiling area to 1.50 or 2 m with remaining usual width of 0.20 to 0.40 m in the floor area.
  • the outer surface includes different acute angles with the vertical over its height. These different acute angles, as well as preferred, may be chosen to be positive and negative with respect to a transverse plane aligned perpendicular to the vertical plane. Also, the acute angle of an outer surface may be selected dimensionally different, so on, in particular each in a range of about 1 to 30 °, more preferably about 5 to 15 °.
  • Both outer surfaces may include different acute angle with the vertical over their height, both outer surfaces may be designed the same with respect to the acute angle.
  • the outer surface may include two acute angles with the vertical.
  • the shut-down curtains which are usually between 0.20 and 0.40 m wide in the ceiling area and on the floor, can be widened, for example, at a height between 3 and 4 m above the hall floor. This results in a broadening of the separation curtain according to corresponding greater spacing of the relevant curtain tracks transverse to the vertical extent of the same. From this broadening, the curtain track sections extend downwardly and upwardly at an acute angle to a vertical plane. Correspondingly, each curtain track extends from this extension area at an acute first angle to an end area, for example a ceiling area, and in the opposite direction, including a second acute angle to the other end area, for example the floor area.
  • the end regions preferably have the smallest widths, in particular smaller widths than the separation curtain in the region of the extension.
  • the width of the separation curtain in the direction of the end regions preferably decreases successively.

  • the result is preferably a roof-like design of the curtain web with a in use state, i. in the lowered state, preferably horizontally extending ridge line, from which extend downwards and upwards curtain track sections roof area like.
  • the spreading of the curtain tracks results in a widening compared to the width in the floor or ceiling area to a level which corresponds to 1.5 to 5 times the width of the curtain in the floor and / or ceiling area.
  • a spreading of the curtain tracks on, for example, 0.8 m, 1 m or 1.2 m may be given.
  • the spreading of the curtain tracks can be provided at two opposite arranged curtains (eg for the separation of a central hall section in a three-compartment sports hall) in different vertical heights. For example, there may be a spread in the area of one curtain at a height of 3 m and at the opposite curtain at a height of 4 m.
  • a pneumatic spreading can be given by one or more airbags are inflated in the relevant altitude to cause the spread. It is advantageous in this case to carry out the spreading only when the separation curtain is in itself in a completely lowered position. It also appears expedient first to empty the air cushion or pillows, for example, by a pump, and only then to initiate the usual snatching the curtain.
  • Electromechanically moreover, via a pneumatically or hydraulically operated mechanism.
  • a pneumatically or hydraulically operated mechanism for example, it is possible to provide a lever linkage extending transversely to the longitudinal extent, which moves, for example, by weight, even when lowering the separating curtain into an expanded position.
  • the partition curtain is preferred in terms of space in the area of the hall floor and the hall ceiling not wider than conventional, known curtains. Due to the spreading of the curtain tracks at a height of several meters above the hall floor, the use of the hall or sports operation is in no way impaired. In addition, such a separation curtain, as can be dispensed with high-quality and expensive clothing materials with sound-absorbing surfaces, low cost.
