Definitions

  • the invention relates to an acoustic adjusting wall, with a frame and at least one wall element, which is wholly or partially formed as a predominantly smooth-surfaced formed nonwoven made of plastic.
  • Acoustic partition walls are used, for example, in open-plan offices, doctors' practices, hospitals, further education facilities, etc., in order to be able to flexibly define individual work areas and separate them both acoustically and visually from one another.
  • acoustic partition walls are usually not or only partially transparent.
  • acoustic partition walls ensure that, ideally, the sound emanating from a work area is attenuated to such an extent that it does not reach the neighboring work area or only at a greatly reduced volume.
  • Such acoustic partition walls are becoming increasingly popular because, overall, an increase in directly communicating activities in open-plan offices and the flexible composition of project teams or working groups is observed.
  • many so-called "Meeting Points” are required, in which creative discussions and problem solutions can be done by several people.
  • this requires partition walls with a high degree of sound absorption and, on the other hand, a low weight of the partition walls, in order to be able to implement the required flexibility without great effort and excessive efforts.
  • An acoustic wall of the structure described above is, for example, in the DE 20 2013 011 608 U1 described. This is about an acoustic wall element, which is designed as embossed beads having plate made of felt. As fibers, man-made fibers or synthetic fibers can be used become.
  • the plate is preferably designed as a needle felt, wherein a hooking of the fibers by means of a jet of water or at least one binder is carried out.
  • the known acoustic wall element not only a room divider or a partition can be realized, but also a furniture part or a panel.
  • the well-known acoustic wall is designed by the resort to particular needle felt relatively massive, especially since the individual plastic fibers are bonded together by binders. Such a design is obviously required in order to impress the additional beads can.
  • the acoustic wall realized in this way is fixed in terms of its areal extent and does not allow changes.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem of further developing such an acoustical wall so that not only the highest possible acoustic attenuation is made available at a low weight, but in particular the additional possibility of increasing the area exists.
  • a generic acoustic working wall in the invention is characterized in that in a cavity of the frame at least one sound-absorbing extract element is arranged, which can either be pulled out of the cavity or inserted into the total area change of the acoustic adjustment wall.
  • the acoustic working wall is not only equipped with a sound-absorbing effect of the wholly or partially as predominantly smooth-surfaced form fleece made of plastic wall element is provided.
  • the frame carrying the wall element according to the invention has a cavity which is generally slit-shaped. In this typically slot-shaped cavity of the frame, the at least one extract element is received.
  • the pull-out element is in turn designed to be sound-insulating, so that the pull-out element can be pulled out of the cavity for the total change in area of the acoustic adjustment wall or pushed into it. In the extended state of the pullout element with respect to the cavity, a nearly doubling of the area of the acoustic wall is observed. Because the extension element can correspond to its surface extent forth almost the surface extent of the wall element carried by the frame. In this context, conventional stops prevent the pull-out element from being separated from the frame. In addition, the sound-absorbing extension element is generally equipped with bottom-side pull-out rollers.
  • the frame generally has feet.
  • the feet can also be designed so that they surround the frame with the wall or the elements below. This is of course not mandatory, but represents a particularly elegant embodiment.
  • the wall element can be placed with the feet at the desired site. If it is desired to increase the total area of the acoustical adjusting wall realized in this way, for example, the extracting element provided in the interior of the cavity of the frame can be pulled out completely. If a change in the total area of the acoustic wall is not required, then the extract element remains in Cavity of the frame. Of course, intermediate positions are also conceivable.
  • the pull-out element itself is designed to be sound-insulating in order not to counteract the sound-insulating effect of the acoustic setting wall when the pull-out element is pulled out.
  • the extract element is at least partially transparent. This underlines the optional character of the pullout element.
  • the extract element is advantageously made of a transparent plastic.
  • plastics such as polymethyl methacrylate (PMMA), commonly referred to as “Plexiglas” have proven to be favorable.
  • the aforementioned plastic is also equipped with the advantage that it is UV-resistant.
  • other plastics such as polycarbonate (PC), PVC (polyvinyl chloride) or PETC can also be used.
  • PC polycarbonate
  • PVC polyvinyl chloride
  • PETC polyvinyl chloride
  • the latter plastic is a glycol-modified polyethylene terephthalate.
  • the output element can in principle also be made of glass and in particular safety glass. As a rule, however, the expression element will be made of a transparent plastic, even in order to keep the total weight of the acoustical adjusting wall according to the invention realized as low as possible.
  • the pull-out element is coated on one or both sides with a microperforated film.
  • a microperforated film If the extract element is designed at least partially transparent, you will be at this Work with a transparent microperforated film.
  • the microperforation of the film takes place in such a way that the film is equipped with a multiplicity of microperforations, that is to say with holes which typically have a diameter of less than 1 mm and preferably of 0.5 mm and less.
  • the extract element is equipped on its surface with a microstructure, which unfolds particular sound-absorbing effect in the most relevant frequency range from 100 Hz to 5000 Hz. In fact, in particular in open-plan offices or in connection with the fields of application already mentioned above, frequencies in this area are typically observed and must be effectively insulated. This is ensured by the microperforated film.
  • the output element is equipped on one or both sides with a microstructured surface.
  • a microstructured surface can be applied, for example, with a laser.
  • Sandblasting is also possible in this context, as are other microstructuring methods.
  • the microstructuring comparable to the microperforated film applied to the drawer element on one or both sides, has the effect of absorbing incident sound and suppressing any possible sonic reflections as much as possible.
  • the wall element is also equipped with a comparable degree of sound absorption.
  • the invention proposes that the wall element a fiber composite is made.
  • the fiber composite in turn consists of plastic fibers which are bonded together mechanically and / or chemically and / or thermally binder-free.
  • plastic fibers are typically polyester fibers are used.
  • the binder-free compound of the plastic fibers and polyester fibers in particular is usually made and implemented so that the respective plastic fibers are first wetted with a plasticizer solution and then glued together at an elevated temperature.
  • the invention recommends temperatures in the range of about 80 ° C to 160 ° C. At such temperatures, the melting point of the plastic fibers used is generally reached or slightly exceeded, so that in a subsequent pressing operation, taking into account the specified elevated temperature, the individual plastic fibers are connected without additional binder introduced at their crossing and touching points.
  • Such an approach is basically in the DE 1 237 057 A or even the DE 1 469 347 A described.
  • the sound-absorbing effect can be attributed to the fact that the formed fabric is basically smooth and macroscopically smooth, however the plastic fibers bonded to one another without a binder microscopically define a spatial network of the plastic fibers coupled to one another in only intersection and contact points with spaces remaining therebetween in a chaotic arrangement. As a result, an optimal surface is provided for the absorption of incident sound, which at the same time effectively suppresses any sound reflections.
  • the wall element has a material thickness of up to approx. 50 mm. In particular, a material thickness of up to about 30 mm and preferably one in the range of 5 mm to 20 mm is observed.
  • the wall element is generally completely or completely formed as a predominantly smooth-surfaced formed nonwoven made of plastic, whose production and properties have been previously described in detail.
  • a binder-free produced molded fabric also has a specific weight of less than 0.6 g / cm 3 , it is clear that in a frame made of aluminum hollow profile, for example, the weight the acoustic partition wall according to the invention can be set particularly low.
  • the acoustic wall can be designed with a total weight of, for example, up to 10 kg or up to 5 kg, so that the acoustic partition in question can easily be moved around within a large office.
  • workspaces can be defined differently and their size and topology can be changed.
  • main benefits are the main benefits.
  • the frame can be equipped on both sides with a wholly or partially designed as a predominantly smooth-surfaced formed non-woven plastic wall element. So you will typically proceed when the inventive Acoustic partition wall should act as a room divider. However, if the acoustic adjustment wall is placed, for example, at the end or at the edge of an arrangement of office tables, it is also possible to work with differently designed wall elements. In this case, it is recommended that the frame workplace side is equipped with the wholly or partially formed as a predominantly smooth-surfaced form non-woven plastic wall element, ie in the direction of the workplace. In contrast, the opposite wall element, which as it were away from the workplace and is arranged opposite, made of, for example, plastic, wood, metal, etc. and mixed forms.
  • the local wall element has an alternative function, for example in the sense of a pin board, as a whiteboard for labeling or as a magnetic wall. Nevertheless, the acoustic wall according to the invention retains its acoustical effect, because the workplace side as before and unchanged, the wall element produced from the respective shaped fabric is realized.
  • the acoustic wall can be optionally adapted in size to the corresponding requirements.
  • the wall elements are designed differently on one side or on both sides.
  • a wall element produced from the predominantly smooth-surfaced shaped nonwoven can be placed next to a wall element made of plastic.
  • the acoustic adjustment wall according to the invention can be flexibly adapted to different requirements. All this is possible taking into account a high degree of sound absorption and at the same time lightweight design, the flexible arrangement of For example, it facilitates acoustic wall in the interior of a large office.
