Definitions

  • the invention relates to a soundproofing body for a mobile partition wall element, a mobile partition wall element and a mobile partition wall system.
  • Mobile wall systems also known as partition systems, are used for the variable subdivision of rooms.
  • Known mobile wall systems have a usually mounted in the ceiling guide rail and possibly a floor mounted guide rail and flat mobile wall elements that can be moved out of a rest position in which they take up little space, and assembled into a complete partition and vice versa.
  • the individual mobile wall elements are clamped by means of movable elements, so-called Ausfahrtik duplex between ceiling and floor.
  • the Ausfahrbuch für für are sunk in the non-actuated state wholly or partially in the mobile wall element. In the extended State they protrude beyond the mobile wall element and are pressed against ceiling or floor or ceiling rail or bottom rail.
  • the ceiling rail can be regarded as part of the ceiling and accordingly the bottom rail as part of the floor.
  • the mobile wall elements or mobile partition elements generally consist of an inner frame to which the outer outer walls are attached.
  • the frame may extend along the boundary lines of the outer walls, it may also have transverse or longitudinal struts which extend through the interior of a mobile partition wall element.
  • Mobile partition wall elements or mobile partition wall systems offer only limited sound insulation or limited sound insulation.
  • Mobile partition wall elements or mobile partition wall systems offer several transmission paths for sound from a room into a room separated by the mobile partition wall system.
  • the main transmission path is that an outer wall of a mobile partition wall element resonates as a resonance membrane with sound waves from a room and transmits them via the frame or other solid components to which the outer wall is connected inside the mobile partition element to the other outer wall.
  • the second outer wall then serves as a loudspeaker diaphragm.
  • This transmission path is similar to the system eardrum ossicle membrane of the human inner ear.
  • a second, subordinate transmission path is the sound transmission, in which an outer wall receives sound waves, transmits them via the air in the interior of a mobile partition wall element to the second outer wall of the mobile partition wall element. Compared to the former direct transmission, however, this second transmission path is strongly attenuated.
  • the said transmission paths for sound by mobile partition walls or mobile partition systems are independent of the materials used in the mobile partition elements. Common materials in this context are metal sheets, metal braces, wood or plastic parts.
  • a mobile wall system is known from a plurality of individual wall elements.
  • the wall elements each have two outer plates, between which a strip of material is arranged made of a compressible insulating material. An overhanging part of the insulating material is compressed during assembly of the wall elements, so that a good soundproofing is achieved at the joint.
  • JP 10102642 relates to a movable sound insulation wall.
  • This forms a frame with rectangular window sections, in each of which a sound insulation body is used, this with the four sides of the window section is locked. Sound-absorbing panels are additionally arranged around the window section.
  • DE 2 100 191 A1 discloses a table unit for transferable partitions with a table frame having at its upper end a clamping member which is displaceable between a retracted position and an extended position and for holding the panel unit in position between an upper and a lower space surface, and a to Moving the clamping member between these positions operable spring-loaded device having an arrangement which is operable to move the clamping member in the extended position.
  • the invention has for its object to improve the sound attenuation in mobile partition elements and mobile partition systems.
  • the object underlying the invention is achieved by a mobile partition element with the features of claim 1.
  • the idea underlying the invention is to interrupt the main transmission path for sound from one side of a mobile partition element to the other side, namely the direct sound transmission through sound conduction in the fixed structures of a mobile partition element, without the stability and structural integrity of a mobile partition element to impair.
  • a sound damping body with a different modulus of elasticity interposed between parts of a mobile partition wall element, which have a certain modulus of elasticity.
  • the extension pressure shoe is divided into two parts, between which only a damped direct sound transmission takes place.
  • the elastic modulus of a solid determines the propagation properties of sound in the solid.
  • a sound damping body made of a plastic, in particular polyacrylic and / or polyethylene. These plastics have particularly good soundproofing properties.
  • a sound-damping body can be produced particularly easily in an injection molding process.
  • transverse struts are provided inside the inner frame for stabilizing the mobile partition element.
  • the outer walls of the mobile partition wall element have in such cases on their insides holding elements, such as hooks, by means of which they are suspended from the cross braces, so that they are very stably fixed at several points over its surface.
  • this also involves a large-scale direct sound transmission.
  • the inner frame has at least one, in particular metallic, transverse strut, and a further sound-damping body is provided, wherein the modulus of elasticity of the sound-damping body differs from the modulus of elasticity of the remaining material or the other materials of the outer walls and / or the inner frame wherein the sound attenuation body is adapted to be disposed between at least two parts of the inner frame and the outer walls for acoustic decoupling, wherein the sound attenuation body is formed as a support member having recesses, of which a first recess for positive and / or non-positive and / or or frictional attachment of the sound-absorbing body is formed on the transverse strut of the inner frame and at least a second recess as a holder for attachment or suspension of at least one outer wall of the mobile partition wall element are formed on the Schalldämpfungsêt.
  • a sound attenuation body is used for acoustic decoupling between an outer wall and a transverse strut and at the same time acts as a fixed point for the outer wall on the transverse strut.
  • the outer walls are connected at their circumference in each case over a large area with the inner frame, so that the inner frame is a critical point in the sound transmission. It is therefore particularly advantageous if a further sound-damping body is provided, wherein the modulus of elasticity of the sound-damping body differs from the modulus of elasticity of the remaining material or the other materials of the inner frame, wherein the sound-damping body is formed to the acoustic decoupling between at least two parts of the inner frame to be arranged, wherein the sound-damping body for attachment between two parts of an at least two-part inner frame, each of which is provided a part for supporting an outer wall, is formed.
  • the sound damping body so the inner frame is divided into several, not directly in contact with each other, frame parts, each of which frame part is in each case only with an outer wall in conjunction. The sound transmission through the inner frame is therefore damped by the sound absorbing body.

  • a profile forms the lateral border of the mobile wall element. With the vertical profiles, for example, adjacent mobile wall elements abut each other. Since the profile is connected to both outer walls, a profile forms a sound bridge, which can be interrupted by the use of a Schalldämpfungs stresses.
