Description

The 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 variable subdivision of spaces. Known mobile wall systems have a usually mounted in the ceiling guide rail and possibly a guide rail attached to the floor and flat mobile wall elements from a resting position where they take up little space, moved out and put together to a complete partition can and vice versa.

The individual mobile wall elements are realized by means of movable elements, so-called Ausfahrdruckschuhe, braced between the ceiling and floor. The Ausfahrdruckschuhe are fully or partially in the non-actuated state sunk in the mobile wall element. When driven out, they protrude above the mobile wall element out and are pressed against ceiling or floor or ceiling rail or bottom rail. In the context of the invention, the ceiling rail as part of the Ceiling and accordingly the floor rail as an ingredient of the soil.

The Mobile wall elements or mobile partition elements generally exist from an inner frame to which the outer outer walls attached are. The frame may extend along the boundary lines of the outer walls, it can also have transverse or longitudinal struts, extending through the interior of a mobile divider element.

Over a Mechanics for extending extension pressure shoes are the extension pressure shoes as well connected to the frame of a mobile partition element.

In acoustically, conventional mobile offer Partition elements or mobile partition walls only limited sound insulation or a limited one Sound insulation. Mobile partition wall elements or mobile partition wall systems offer this several transmission paths for sound from a room into a partitioned by the mobile partition wall system Room. The main transmission route is that an outer wall a mobile partition element as resonance membrane with sound waves from a room resonates and this over the frame or other fixed components, with which the outer wall in the interior of the mobile partition element connected to the other outer wall transmits. The second outer wall then serves as a speaker diaphragm. This transmission path is comparable with the system eardrum ossicle membrane of the human inner ear.

One second, subordinate transmission path is the sound transmission, at the outside wall Sound waves picks them up the air inside a mobile partition element to the second outer wall of the mobile partition element transmits. Compared to the first direct transmission is this second transmission path but strongly damped.

Finally, can Sound still through cracks between the mobile partition elements a mobile partition system or between the elements and the Ceiling or the floor or the walls penetrate a room. As these are usually sealed with sealing lips, but is also this transmission path heavily steamed.

The named transmission paths for sound through mobile partition elements or mobile partition systems are independent of the materials used in the mobile partition elements. Usual materials in this context are metal sheets, metal braces, wood or plastic parts.

Of the Invention is the object of the sound attenuation at Mobile partition elements and mobile partition systems to improve.

The The object underlying the invention is achieved by a Schalldämpfungskörper for a mobile Partition element with an inner frame, two with the inner Frame, in particular detachable, connected external walls and at least one Ausfahrdruckschuh, wherein the modulus of elasticity the sound-absorbing body itself from the modulus of elasticity the rest Material or the rest Materials of the outer walls and / or the inner frame and / or the at least one Ausfahrdruckschuhs differs, wherein the Schalldämpfungskörper formed is to acoustically decouple between at least two parts of a mobile partition element to be arranged, the two parts the mobile partition element parts of the inner frame, the outer walls and / or of the Ausfahrdruckschuhs are.

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. There In FIG. 2, between parts of a mobile partition wall element having a certain modulus of elasticity, a silencing body is interposed with another modulus of elasticity.

The modulus of elasticity a solid determines the propagation properties of sound in the solid. If Sound passing through a solid is directed to a phase boundary to a material with a other modulus of elasticity only a part of the sound is transmitted into the other body and another portion of the sound is reflected at the phase boundary. If the part of the sound that has been transmitted into a sound-deadening body to the next Phase boundary to a component of a mobile partition element, so is again a part of the sound is reflected at the phase boundary and only a part in the other solid state transmitted. Thus finds a double attenuation of the transmitted sound. Accordingly, the amplitude of sound coming from an outside wall a mobile partition element over the internal structure of the element is directed to the other outer wall, strong attenuated.

The previously explained Principle is applicable to all structural components of a mobile partition element, including inner frame, inner frame cross braces or extension pressure shoes or the connection of Ausfahrdruckschuhen with the inner frame a mobile partition element.

advantageously, There is a Schalldämpfungskörper a plastic, in particular polyacrylic and / or polyethylene. These plastics have particularly good soundproofing properties.

Especially just lets a sound-damping body advantageously produced in an injection molding process.

at usual mobile partition elements are cross struts inside the inner frame provided for stabilizing the mobile partition element. The Exterior walls of the mobile partition wall element have in such cases on their insides holding elements, for example, hooks, on, by means of which they on the cross struts suspended so they are very stable at several points above theirs area are fixed. However, this is also a large-scale direct sound transmission connected. It is therefore particularly advantageous if the sound-absorbing body as Supporting element is formed, which has recesses, of which a first recess for the positive and / or non-positive and / or frictional attachment of the sound-absorbing body a, in particular metallic, cross strut of the inner frame is formed and at least a second recess as a holder for attachment or suspension at least one outer wall of the mobile partition element are formed on the sound damping body.

In In this case, a Schalldämpfungskörper the acoustic decoupling between an outer wall and a transverse strut used and acts as a fixed point for the outer wall at the crossbar.

The Outside walls are at its periphery in each case with a large area connected to the inner frame, so that the inner frame a neuralgic point in the sound transmission represents. It is therefore particularly advantageous if the sound-absorbing body for Attachment between two parts of an at least two-part inner Frame, each of which provides a part for supporting an outer wall is, is educated. By means of the sound-damping body is so the inner frame in several, not directly in contact, frame parts divided, each of which frame part in each case only with an outer wall communicates. The sound transmission through the inner frame is therefore damped by the Schalldämpfungskörper.

Preferably is the Schalldämpfungskörper to Attachment between two outer parts a Ausfahrdruckschuhs a mobile partition element formed. Similar to in the case of the inner frame also the Ausfahrdruckschuh is thus divided into two parts, between which only a muted direct sound transmission takes place.

Prefers is the sound absorbing body in this Case with an extension pressure shoe of a mobile partition element connected and / or in a Ausfahrdruckschuh a mobile partition element integrated.

advantageously, is the Schalldämpfungskörper to Attachment between an extension pressure shoe and the inner frame a mobile partition element formed.

Also It is advantageous if the sound-damping body arranged in a profile is, in particular mechanically pressed with other parts of the profile is. Such a profile forms the lateral border of the mobile wall element. Bump with the vertical profiles for example, adjacent mobile wall elements to each other. Since that Profile connected to both exterior walls Also, a profile forms a sound bridge through the insert a Schalldämpfungskörpers interrupted can be.

The invention underlying Aufga be is also solved by a mobile partition wall element having an inner frame, two outer walls connected to the inner frame and a sound damping body according to the invention as described above.

advantageously, the inner frame has at least one, in particular metallic, Cross strut, wherein between the cross brace and at least one outer wall an inventive Schalldämpfungskörper arranged is. It is particularly preferred if for the outer walls of the mobile partition wall element separated on a transverse strut or several cross struts of the inner Provided frame arranged silencer body are on which only one outer wall can be fastened or is attached.

In In this case, a direct sound transmission finds only in a multiple damping instead, because sound that is picked up by an outer wall becomes first over one Damping body on one Transfer crossbar, which already has two phase transitions to damping contributed. The sound is transmitted from the cross strut to another silencer body on which the second outer wall is fixed so that the sound has to cross a total of four interfaces. This causes a very effective Soundproofing.

Further The object underlying the invention is also by a mobile partition wall system with at least one mobile according to the invention Partition element, as described above, solved.
