Description

description

The invention relates to a holding device for at least one mobile partition element, with at least one rail having at least one guide slot for guide rods of partition elements, wherein the holding device along the rail has receptacles for ceiling elements of a cover. The invention further relates to a guide system for at least one mobile partition element having a main arm with a main guide slot and at least one side arm with a Parkführungsschlitz, and a mobile partition wall element.

Mobile wall systems, also known as partition systems, are used for the variable subdivision of rooms. Known mobile wall systems have a guide rail, which is usually mounted in a suspended ceiling or suspended ceiling, and optionally a floor-mounted guide rail and flat mobile wall elements which are moved out of a rest position in which they take up little space and joined together to form a complete partition wall can be and vice versa.

The individual mobile wall elements are clamped by means of movable elements, so-called Ausfahrdruckschuhe between ceiling and floor. The Ausfahrdruckschuhe 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 the ceiling or floor or ceiling rail or bottom rail.

In terms of acoustics, conventional 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.

A transmission path is that an outer wall of a mobile partition wall element resonates as resonant membrane with sound waves from a room and transmits them via the frame or other solid components to which the outer wall is connected in the interior of 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. The recorded sound can also be transmitted via the air in the interior of a mobile partition wall element to the second outer wall of the mobile partition wall element.

Sound can also be generated by cracks between the mobile partition wall elements of a mobile partition wall system or between the elements and the ceiling or the floor or the walls of a mobile partition wall system Space penetrate.

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 metals, wood or plastics or composites.

Conventional holding devices for mobile partition wall elements comprise a rail in the form of, for example, a hollow profile with a central guide slot for guide rods of partition wall elements which are suspended on their upper side on a supporting ceiling. Thus, the supporting ceiling carries the weight of the mobile wall, as far as the mobile wall elements are not supported yet by means of extended Ausfahrdruckschuhe on the ground.

The rail profiles are laterally provided, for example, on their underside with inverted T-profiles, wherein on both sides in each case a horizontal arm of the T-profile protrudes laterally beyond a side wall of the rail profile. On the towering arm of the T-profile, there are ceiling elements or panels of a supporting ceiling, so that the suspension ceiling or its ceiling panels or elements are substantially flush with the underside of the rail profile. The T-profiles thus form receptacles for the ceiling elements of the suspension ceiling.

Between the ceiling and the supporting ceiling is formed in this way a shallow cavity in which sound preferably propagates. Sound can also be transmitted from a suspended ceiling panel via the T-profiles and the holding device, ie the rail profile, to the suspended ceiling panel on the other side.

The present invention has for its object to achieve an improved sound insulation for mobile wall systems, in particular sound transmission paths on the ceiling and the mobile wall elements themselves are prevented or mitigated.

The object underlying the invention is achieved by a holding device for at least one mobile partition element, with at least one rail having at least one guide slot for guide rods of partition elements, wherein the holding device along the rail has receptacles for ceiling elements of a suspension ceiling, characterized in that at least one sound-absorbing body is provided, which insulates along the rail transmission of structure-borne sound. In this case, "along the rail" in the context of the invention means that at no point along the rail structure-borne noise is transmitted uninsulated from one side of the holding device to the other side. The sound-absorbing body is aligned parallel to the rail.

In the context of the invention, a receptacle for a ceiling element is also a support surface for a ceiling element or a system component which has such a support surface for a ceiling element. A sound-absorbing body is in the context of the invention, a body which consists at least substantially of a sound-absorbing material.

The basic idea of the invention with regard to the holding device according to the invention is that in this way a sound insulation for structure-borne noise is generated, that is to say for sound which is transmitted and transmitted in solids. The structure-borne noise must pass through at least one sound-absorbing body on the way from a ceiling element, for example a suspended ceiling panel, through the retaining device to the next ceiling element. there can be arranged between a ceiling element and the sound-absorbing body or the sound-absorbing body and the rail and other non-sound insulating components of the holding device. Even in such a case, the sound-absorbing body is still arranged sound-insulating between the ceiling element and the rail or adjacent ceiling elements. In this way, a sound transmission from a ceiling element of a ceiling to the opposite ceiling element is prevented, which previously took place directly on the rail or the rail profile. Instead, a sound insulation body is switched on, which acoustically separates the two ceiling elements of the suspension ceiling or suspended ceiling panels.

In an advantageous embodiment, the receptacle is designed as a sound-absorbing body. This means in the context of the present invention, that the essential parts of the corresponding system component consist of a sound-insulating material, so that the recording has no sound bridges with no or only slightly sound-absorbing materials for uninsulated sound transmissions. For the purposes of the invention, this also means that the receptacle is insulated from a ceiling element by means of a sound insulation body.

Alternatively or additionally, the sound-absorbing body is preferably arranged between the rail and the at least one receptacle for a ceiling element.

The sound-absorbing body preferably comprises a material with a low elastic modulus of less than 3 GPa, in particular less than 0.5 GPa, in particular less than 0.1 GPa, or consists at least essentially of such a material. Thus, the sound-absorbing body has a low modulus of elasticity which differs from the much higher moduli of elasticity of the adjacent components of the holding device and / or the supporting ceiling elements.

In the context of the invention, the term elastic modulus is understood to mean the technical definition of the static modulus of elasticity. The modulus of elasticity is a measure of how much resistance a solid opposes to its deformation and determines the propagation properties for sound in the solid state. Thus, the propagation velocity of sound in solids and their acoustic characteristic impedance depends on the modulus of elasticity.

The metals and hard plastics or woods usually used in mobile partitions have elastic moduli of more than 10 GPa. For example, the modulus of elasticity of metals in steels is about 200 GPa (1 GPa = 10 ⁹ N / m ² ), for aluminum about 70 GPa. Sound-absorbing bodies according to the invention have a modulus of elasticity of less than 3 GPa, preferably less than 0.5 GPa, more preferably less than 0.1 GPa. Examples of particularly suitable materials are elastomers ("rubber") with moduli of elasticity between 0.01 and 0.1 GPa, polystyrene with elastic moduli between 0.001 and 0.01 GPa or plastics and acrylates, for example Plexiglas, with up to 3 GPa. Wood with vertical fibers or composite materials with correspondingly low moduli of elasticity are also suitable.

Because of the different moduli of elasticity and the acoustic characteristic impedances of the materials used, sound insulation takes place by reflection of the sound waves at phase boundary surfaces. When sound passing through a solid encounters a phase boundary with a material having a different sound impedance, only part of the sound will pass into the other body transmitted and reflected the remaining portion of the sound at the phase boundary. The acoustic characteristic impedance depends on the density and the speed of sound in the material, the speed of sound in turn depending on the modulus of elasticity and the density. For longitudinal waves, there is a quadratic dependence between the modulus of elasticity and the acoustic characteristic impedance.

If the part of the sound that has been transmitted into a sound-absorbing body, on the next following phase boundary to another component or a boundary surface, so again a part of the sound is reflected at the phase boundary and only a smaller part in the further solid or transmitted further component. Thus, even with the use of a single sound-absorbing body between two components takes place a double attenuation of the transmitted sound by reflection. Accordingly, the amplitude of the sound, which is passed from a sheet over a sound absorbing body and a rail or a rail profile to the next ceiling element, strongly attenuated. Preferably, according to the invention sound insulation bodies are used on both sides of the rail.

The feature that the sound absorbing body "at least substantially" consists of such a material means in the present invention that the essential parts of a sound absorbing body consist of such a material, so that no sound bridges of materials with higher moduli of elasticity, on the structure-borne sound can be forwarded undamped or little steamed.

The previously explained principle is applicable to all structural components of the holding device, by means of which adjacent parts can be decoupled. The rail profile itself, provided it out Metal or a similarly good sound-conducting material is made, forms in each case a sound bridge.

Advantageously, the sound-absorbing body comprises a sound-absorbing material or at least substantially consists of such a material. The sound insulation is thus based on a further, possibly alternative, principle, namely the dissipative sound absorption, ie the absorption or conversion of sound energy into heat energy. Many low modulus materials, such as rubber, also provide dissipative sound absorption. Such materials have a complex modulus of elasticity, the real part of the modulus of elasticity being related to the above-described effect of sound insulation by reflection at phase boundaries, and the imaginary part of the modulus of elasticity to the dissipative sound insulation.

Also in connection with the dissipative sound insulation is the feature that the sound absorbing body "at least substantially" consists of such a material, so to understand that the essential parts of a sound absorbing body consist of such a material, so that no sound bridges of materials with less or Lack of dissipative sound insulation arise over the structure-borne sound can be forwarded undamped or little steamed.

In advantageous developments with independent inventive rank, the holding device is further developed in that the rail is arranged on at least one upper holder profile and at least a lower holder profile is designed as a receptacle for a ceiling element, wherein the at least one sound insulation body connects the upper holder profile with the lower holder profile. By means of this development according to the invention are the Ceiling elements of the rail or the rail profile by means of at least one sound-absorbing body decoupled. The underside of the rail profile is no longer flush with the underside of the ceiling elements. The damping body works in this case as a supporting element of the holding device. The holder profiles themselves are made of a rigid material, for example metal, for example aluminum.

Advantageously, an upper holder profile and a lower holder profile are each connected to one another via a plurality of sound insulation bodies, wherein the sound insulation body, the upper holder profile and the lower holder profile enclose a cavity. The arrangement of several sound-absorbing body between the holder profiles ensures greater mechanical stability and thus for safe installation.

Advantageously, the cavity is at least partially filled with a Dämmmasse. As Dämmmasse next to a turn rubber-elastic mass and any other heavy mass, such as cement, plastic filling, metal or the like suitable, which means that the heavy Dämmmasse is very difficult to vibrate in the cavity and thus sound bad of a ceiling element transmits to the rail profile. In the case of a hardly damping heavy mass, there should be no contact contact of the mass with the upper holder profiles.

It is preferably provided that the cavity is designed to receive electrical cables. Thus, the interior of the rail profile, in which carriages of the partition wall elements are moved, can be mechanically separated from the space in which electrical lines are guided. In this way, electrical lines even when mounting a holding device according to the invention be installed immediately, while otherwise would have to be postponed in a separate assembly step.

In a further development of independent inventive rank, the rail and the upper holder profile by means of a clip or locking mechanism with grooves and hooks are connected to each other. In this way, it is possible to produce holding devices according to the invention in a modular system and to flexibly adapt to different applications based on less basic components. Thus, it may be that different partition systems make different rail profiles necessary, for example, differ in height, but while the connection of the holding profile with different rails via a locking mechanism or clip mechanism is possible. Thus, it is possible to reduce the number of different models of holder profiles and / or rail profiles.

In an advantageous development, the upper holder profile has at least one sealing lip for sealing against a ceiling element. The sealing lip fulfills both the task of mechanically stabilizing the ceiling element between the lower and the upper holder profile as well as by suitable choice of material, such as a rubber-elastic material to acoustically decouple the ceiling element of the upper holder profile.

Preferably, the guide slot is sealed by means of oppositely disposed sealing lips. This prevents that the rail profile acts as a sound-conducting channel or resonance chamber for sound that would otherwise penetrate from the room through the slot in the rail profile. For this purpose, advantageously, the upper holder profile and / or the lower holder profile on a profile for holding a sealing lip.

The sealing lips are preferably abutting hose profile lips or overlapping flat profile lips. In both cases, the sealing lips are made of an elastic material, so that at a position at which opens a guide rod of a partition wall element in a carriage in the interior of the rail profile, the sealing lips release the space for the guide strands, but close again before and behind the guide rod by overlapping or hitting each other.

Preferably, the upper holder profile has a support surface for at least one insulation board, which is arranged in the installed state between a ceiling and a supporting ceiling. The cavity between the false ceiling and the load-bearing ceiling is also a good sound conductor, in which sound can propagate almost unhindered. The arrangement of insulation boards between the ceiling and the supporting ceiling along the upper holder profile or the rail profile also prevents in this cavity the propagation of sound waves from a subspace in the other subspace of divided by the mobile wall in two subspaces space.

The object underlying the invention is also achieved by a guide system for at least one mobile partition element having a main arm with a main guide slot and at least one side arm with a Parkführungsschlitz, wherein both the main arm and the side arm according to the invention have holding devices. The side arms, which in some cases are perpendicular to the main arm, generally serve to place the divider elements in a parking position which is occupied when the entire room is not to be divided by the mobile divider wall. In this case, the mobile partition wall elements stowed on the edge of the room. Also in these side arms, as well as in the main arm, which defines the active position of the mobile partition wall system, a sound insulation according to the invention is preferably realized.

The object underlying the invention is finally fulfilled by a mobile partition wall element, which is further developed in that it has two inner frame, which are each connected to an outer wall and in each case with at least one Ausfahrdruckschuh, in particular between the outer walls, a Dämmraum is provided. The inventive mobile partition wall element with two parallel frames and in particular a Dämmraum an advantageous plurality of interfaces and Schalldämpfungskörpern is constructed, each interface separates two materials with different modulus of elasticity, so that a very good sound insulation occurs.

If inner walls are arranged between the frames, advantageously further sound-reducing boundary surfaces are used. The insulation chamber is preferably filled with an insulating material.
Even a Dämmraum, which is filled with air, provides additional damping. If a damping material is filled in the insulation chamber, an even higher insulation is achieved.

Preferably, at least one cover element is provided which connects the partition wall body. Also at the foot of the partition body, the partition body can be preferably connected to each other by means of a foot member. The cover element and / or foot element accommodates in such a case preferably the mechanism including the Ausfahrdruckschuhe.

Advantageous materials for sound insulation bodies are elastomers, Styrofoam or softer plastics, in particular polyacrylic and / or polyethylene. These plastics have a particularly good sound insulation property. Sound insulation body made of the latter plastics can be produced particularly easily in an injection molding or continuous casting process.

The invention will be described below without limiting the general inventive idea by means of embodiments with reference to the drawings, reference being expressly made to the drawings with respect to all in the text unspecified details of the invention. Show it:

In the following figures, identical or similar elements or corresponding parts are provided with the same reference numerals, so that a corresponding renewed idea is dispensed with.

In Fig. 1 a space with a mobile wall system or a mobile partition wall is shown in perspective. In front of the mobile wall, the floor 50, side walls 51, 52 and the suspended ceiling 53 or suspended ceiling of the divided space are shown. Through gaps in the mobile wall, the rear wall 54 can be seen.

The mobile wall consists of mobile wall elements 61, 62, 63, 64, 65, which are suspended on guide rails 55. The elements 61 and 62 are already braced in their predetermined positions in the mobile wall between the floor 50 and ceiling 53. The mobile wall element 63 is in a position just before the connection with the mobile wall element 62. By means of a crank, the mobile wall element 63, vertically clamped between the floor 50 and ceiling 53.

The mobile wall elements 64 and 65 are located on the right side in a parking position, which occupies little space. They are not clamped in the parking position between the ceiling 53 and floor 50, their Ausfahrdruckschuhe are sunk in the mobile wall elements 64, 65.

In the cover 53, a holding device 1 is shown, in which the mobile wall elements 61 to 65 are held. In the immediate vicinity of the side wall 52, a side arm is shown with a holding device 2, in which the mobile wall elements can be 61 to 65 parked.

In Fig. 2 a holding device according to the invention is shown schematically in section. On a supporting ceiling 10 by means of support rods 14, 14 ', a rail profile 13 of a holding device for a mobile partition wall system attached. The rail profile 13 is rectangular in cross-section and has at the bottom center a gap or slot through which a guide rod 16 of a partition wall element (not shown) is guided. The guide rod 16 opens into a carriage 15 with rollers 17 on the underside and lateral guide rollers 18, 18 ', which are arranged in perspective behind two vertical support members (without reference numerals).

At the lower two corners of the rectangular rail profile 13, two inverted T-profiles 12, 12 'are fixed, on the outwardly facing arms in each case a ceiling element 11, 11' and a plate of a supporting blanket rests. The cover is connected at this point by means of the T-profiles 12, 12 ', the rail section 13 and the support rods 14, 14' with the supporting ceiling 10.

According to the invention, the T-profiles 12, 12 'are designed as receptacles in the form of sound-absorbing bodies 12, 12'. This prevents that sound from the ceiling element 11 of the suspension ceiling on the T-profile 12, the rail section 13 and the T-profile 12 'penetrates directly into the ceiling element 11 of the suspension ceiling, if it would be forwarded without significant attenuation.

Both the rail profile 13 and the T-pieces 12 are usually formed in the prior art of metal or other hard and sustainable material. Likewise, structure-borne noise from the load-bearing ceiling 10 can be transmitted essentially uninsulated to the ceiling elements 11, 11 '. This is with T-profiles 12, 12 'designed as sound-damping elements are likewise prevented.

Alternatively, the T-profiles 12, 12 'in Fig. 2 also made of metal, but their bearing surfaces be provided with sound-absorbing bodies.

In Fig. 3 a holding device 1 according to the invention is shown schematically in section. For clarity, in Fig. 3 the carriage 15 and the guide rod 16 of a partition element not shown.

In contrast to the embodiment according to Fig. 2 are not T-pieces attached to the underside of the rail profile 13, but upper holder profiles 20, 20 'connected by means of a clip mechanism with the rail profile 13. For this purpose, the rail profile 13 recesses 22, 22 'for an upper clip and for a lower clip 23, 23', in the hook profiles 21, 21 'of the upper holder profile 20, 20' engage and thus the upper holder profiles 20, 20 'mechanically connect with the rail profile 13.

About two insulation and support body 27, 27 ', 27 ", 27"', the sound insulation body, the upper holder profiles 20, 20 'with lower holder profiles 25, 25' are connected, which are parallel to the upper holder profiles 20, 20 ' run. The connection is in each case such that the upper and lower holder profiles 20, 20 ', 25, 25' have clip profiles 26, 26 ', 26 ", 26"' into which thickened end pieces of the insulating and carrying bodies 27, 27 '. , 27 ", 27" 'are introduced. Incidentally, the insulation and support bodies 27, 27 ', 27 ", 27"' themselves are essentially sheet bodies.

Between the insulating and supporting bodies 27, 27 ', 27 ", 27"' and the lower and upper holder profiles 20, 20 ', 25, 25' are two, in particular substantially rectangular, cavities formed in the example shown in FIG Fig. 3 with an insulating mass 28, 28 ', such as a cement or a plastic filling, are filled. It can also be introduced as a heavy mass metal.

The insulation and support body 27, 27 ', 27 ", 27"' and, if the cavity is completely filled, the insulation filling 28, 28 'form the only connection between the lower support body 25, 25' and the upper support body 20, 20th '. These elements provide a good separation of the sound from the lower to the upper holder profile.

The insulation and support body 27 - 27 "'can be made in one piece with the upper holder profiles 20, 20' and optionally the insulation filling 28, 28 '.

On the outside is in each case a ceiling element 11, 11 'of a suspension blanket on the lower holder profile 25, 25', without touching the upper holder profile 20, 20 '. For better mechanical stability and further acoustic decoupling provide sealing lips 24, 24 'on the upper holder profile 20, 20'. These cause both a clamping action and a barrier against sound, which could otherwise penetrate at the top of the ceiling element 11 between the upper holder profile 20, 20 'and the lower holder profile 25, 25'.

The upper holder profiles 20, 20 'each have on their outer side bearing surfaces for insulation boards 31, 31', which are each arranged between an upper holder profile 20, 20 'and the supporting ceiling 10 and prevent sound, for example, from the left side in Fig. 3 above the ceiling element 11 to the cavity on the right side between the ceiling element 11 'and the supporting ceiling 10 passes.

The rail profile 13 has a main guide slot 34, through which, as in Fig. 2 For example, shown, a guide rod 16 of a partition element can lead to a carriage 15. Thus, from below from the room through this main guide slot 34 no sound can get into the rail section 13 and is forwarded there resonant, the lower holder profiles 25, 25 'each have a holding profile 30, 30' for insulating hoses or sealing tubes 29, 29 ', the in the normal state to touch (solid lines). Dashed lines illustrate the situation when a guide rod 16 (not shown, compare Fig. 2 ) would be present at the interface shown. The sealing hoses would then be deformed so that they would cling to the rod 16 and also in this way little or no sound can get into the rail section 13.

In the FIGS. 4a and 4b an alternative type of sealing lips 33, 33 'for a guide slot 34 is shown. These are flat sealing lips 33, 33 ', which overlap in the middle of the guide slot 34. Both sealing lips 33, 33 'are fastened in clamping holder profiles 32, 32' by lower holder profiles 25, 25 ', wherein the clamping holder profiles 32, 32' describe a narrow opening into which the thickened ends of the flat sealing lips 33, 33 'are introduced that they can not be pulled out in a direction perpendicular to the guide slot 34.

In Fig. 4b the situation is illustrated that a guide rod 16 of a partition element passes through the slot 34. At this point, the upper, left-hand sealing lip 33 is deflected upwards and the lower, right-hand sealing lip 33 'is deflected downwards.

In Fig. 5 a guide system according to the invention is shown, with a main arm and a main guide slot 34 which is expandable upward, and a side arm and a Parkführungsschlitz 35. Shown are also schematically the sealing lips 36, 36 'in the main arm and 36 "and 36"' in the side arm. Dashed lines schematically show the abutting edges or overlapping edges 37, 37 ', 37 "of the sealing lips 36, 36', 36", 36 "'.

In Fig. 6 is a schematic sectional view through a holding device according to the invention and a mobile partition wall element 41 according to the invention shown. The holding device 1 is shown in this case with the elements described above, in particular the rail profile 13 and ceiling elements 11 suspended therein. Inside the rail profile 13, a carriage 15 is shown with the details described above. With the carriage 15, a cross member 44 is connected via a guide rod 16. About vertical decoupling rubber body 43, 43 'stored on the cross member 41 has two frames 42, 42'. The frames 42, 42 'are connected to each other by means of a further, horizontally decoupling, rubber body 43 ".

Each of the frames 42, 42 'supports in each case via connecting elements and mechanisms, not shown, an outer wall 45, 45' and a Ausfahrdruckschuh 46, 46 'from which is pressed up against the holding device 1 and / or the ceiling element 11. The left extension pressure shoe 46 is shown in the extended position and the right extension pressure shoe 46 'in a retracted position. At the top of the Ausfahrdruckschuhe 46, 46 'rubber body for sound decoupling with the ceiling are arranged.

Between the frame 42, 42 'is a Dämmraum 47, which may be filled with air or with a further Dämmmasse. The illustrated construction of the invention has a plurality of interfaces or interfaces and a plurality of dissipative sound-absorbing layers and interconnected, but decoupled by sound-absorbing elements components, resulting in a very strong insulation of the sound transmission. Not shown is the continuations of the partition wall element 41, which opens into a foot element with two Ausfahrdruckschuhen. It may also be between the frame 42, 42 'preferably still be arranged inner walls, which represent further sound-reducing interfaces.

All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with other features are considered alone and in combination as essential to the invention.
