Definitions

  • the invention relates to a cabinet furniture with a furniture body and at least one front blind, which has parallel to each other arranged connectable profile elements and which is guided in arranged on the furniture body guide grooves.
  • Such cabinet furniture are already known from the prior art.
  • profile elements which are articulated to form a shutter with each adjacent profile elements and which are for opening or closing of cabinet furniture.
  • These existing in profile elements arranged in cabinet furniture shutters from the prior art cause the opening and closing material due itself noises.
  • the cabinet furniture in, for example, open-plan offices with a per se high noise level their use leads to further distribute the sound, as on the surface of the sound is reflected back.
  • the resulting background noise especially in a larger office space, is not conducive to the understanding and working climate of the employees.
  • the invention is therefore based on the object to improve the known disadvantages of the prior art and show cabinet furniture that can be produced economically and inexpensively and are particularly improved in terms of sound-absorbing properties.
  • the cabinet furniture according to the invention is characterized in that the profile element has at least one flat profile body into which at least one opening is made.
  • This solution is simple and has the advantage that the sound can penetrate through the opening in the profile body of the profile element in the cabinet furniture and spread there. The sound is at least partially absorbed in the cupboard furniture. The sound reflected back from the cupboard furniture is now at least partly reflected back into the cupboard furniture by the profile elements of the front blind, so that only a very small part of the sound is reflected back into the room.
  • a further advantageous embodiment of the invention can be provided in cross-section only one opening in the profile body of the profile element seen in cross-section.
  • this design according to the invention can be in the longitudinal direction of a profile element reduce the number of openings and thus simplify the production.
  • the width of the opening is less than half the width of the front wall of the profile body of the profile element, preferably less than a third. It has been found in investigations that inexpensive furniture with front blinds can be produced with these specifications, with good sound absorption effect.
  • a soundproofing element is arranged at least in the region of the opening to the opening and can already eliminate large components thereof when the sound penetrates.
  • the penetrating through the openings of the profile body of the profile element sound propagates such that it comes into contact with at least a majority of the surface of the soundproofing element and is absorbed.
  • the Schallabsorbtions can be significantly improved.
  • the soundproofing element is arranged to be movable at least in the region of the opening towards the opening and away from it, so that the penetrating sound moves the soundproofing element in the sound direction and thus contributes to a better absorption of the sound.
  • the soundproofing element is arranged on the front side of the profile body of the profile element, so that advantageously in addition to the sound-absorbing properties, design and design possibilities for customized cabinet furniture are possible.
  • the soundproofing element is arranged on the underside of the profile body of the profile element, so that the openings introduced in the profile body of the profile element channeled the incoming sound to the soundproofing element and the design of a cabinet furniture is the wishes of each customer customizable.
  • the soundproofing element is arranged both on the front side and on the underside of the profile body of the profile element, which leads to even more optimized soundproofing properties of the cabinet furniture.
  • the formation of the soundproofing element as a substantially mat-shaped leads to advantageous production costs of such inventive cabinet furniture.
  • the sound-absorbing material may be a fiber material, with which it is possible to inexpensively achieve good sound-absorbing properties of the cabinet furniture in a simple manner.
  • the sound-absorbing material is a non-woven material, which is characterized by very good sound-absorbing properties and also a very good processability.
  • the soundproofing element can be formed by a membrane, for example made of plastic. With such a membrane, material-specifically targeted desired sound frequencies can be influenced or absorbed. Furthermore, it is advantageously seen that the soundproofing element extends over the entire length of the profile element, which leads to cabinet furniture with optimized Schallabsorbtions für usufactoring.
  • the profile body and or the profile element is formed so that it has fastening devices for fastening the soundproofing element, so that a cost-effective production of such profile elements with optimized Schallabsorbtions für satusky satusky satusky satusky satusky satusky satusky satusky satusky satusky satusky satusky satusky s, etc.
  • the soundproofing element is connected over its entire surface to the profile body of the profile element, which enables cost-effective optimized production, for example, in the coextrusion process known per se.
  • the cabinet furniture according to the invention with the consisting of the profile elements front blind has a sound absorption coefficient according to EN ISO 354 of at least 0.4.
  • the sound absorption coefficient represents the ratio of the equivalent sound absorption surface of a test object to the surface of the test object.
  • the surface of the test object in this case the cabinet furniture according to the invention, is the surface of the floor or the wall which is covered by it.
  • the equivalent sound absorption area of the test object is determined from the difference between the equivalent sound absorption area of the reverberation room (the office room) with and without the test object (cabinet furniture).
  • the equivalent sound absorption area of a room is defined as the hypothetical size of a fully absorbing surface without diffraction effects, which would give the same reverberation time in a room as if it were the only absorbing element in space.
  • the resulting stationary sound pressure level and the decay of the sound pressure level after switching off the sound source by the sound-absorbing properties of the room boundary surfaces, the air in the room and the objects (cabinet furniture) in the room to be influenced.
  • the proportion of sound power absorbed at a surface depends on the angle of incidence of the sound.
  • EN ISO 354 describes a reverberation chamber method for measuring the sound absorption coefficient of acoustic materials used to clad walls and ceilings used or the equivalent sound absorption surface of individual objects, such as cabinet furniture.
  • the determined sound absorption coefficient can be used for comparison purposes and for design calculations in room acoustics and especially in noise abatement.
  • the cabinet furniture according to the invention it is surprisingly possible to reduce the sound in, for example, office space so that an audible reduction in the general noise level for each recognizable or audible.
