Description

The invention relates to a mobile partition wall according to the preamble of claim 1. The mobile partition has a plurality of movable on a running rail wall elements.

From the DE-OS 24 04 784 is a mobile partition with several slidably guided in a running rail wall elements known. Each wall element has a supporting structure, which is formed from a circumferential frame consisting of profiles. On the frame cover plates are mounted on both sides and also attached to other attachments and accessories. The cavity between the cover plates and the frame is filled with heat and sound insulating materials.

The frame-based support structure leads to a high weight of the wall elements and requires accordingly stably executed hanger. The increasing requirements in terms of thermal and acoustic insulation can be achieved with such a structure only by using additional or thicker cover plates with increasing the weight.

Since mobile partitions are manufactured based on varying installation situations and dimensions case by case, in particular, the creation of the frame requires a complex and dimensionally accurate production and connection of profiles. Provision and production of standard components for such wall elements is extremely limited.

In addition, the integration of optional components in such wall elements requires an exact definition of the interfaces to the frame. For example, the usual features of the wall elements with upper and lower sealing mechanisms and consuming due to the design-related conditions of a frame in terms of universal use is limiting. Variants in the structure or the installation situation also require a one-off production here. Changes on site are only possible within the tolerance.

In the EP 0 629 752 B1 is a mobile partition described in the upper and lower end strips of pneumatic lifting elements are activated for sound insulation and to ensure the stability of the individual wall elements. The central arrangement of the lifting mechanism within the respective wall element requires a complex production and limited repair options and when used in a transparent wall, a negative appearance.

In the Austrian patent AT 325262 The partition elements consist of different materials. In order to achieve a high level of sound insulation, the gap is closed to a floor guide rail and the gap to a running rail or the ceiling by a movable up from the floor guide rail profile.

In the DE 92 00 754 U1 a mobile partition wall according to the preamble of claim 1 is described.

The invention has for its object to provide a mobile partition according to the preamble of claim 1, wherein the units are manufacturing and assembly technically simple and universally usable and edge side individual wall elements can be easily and variably arranged.

This object is achieved with the features specified in the characterizing part of claim 1. Advantageous embodiments of the The subject matter of claim 1 are specified in the subclaims, wherein the invention can be applied both in automatic and in manually displaceable wall elements of partitions.

The mobile partition according to claim 1 has the advantage that the production and assembly is substantially simplified by a modular and uniform structure of the units. For this purpose, the individual wall elements of a partition wall have a mounting element in which the structural units are arranged such that they can be exchanged and expanded in a modular manner by means of a uniform assembly and fastening technique. The modular design allows easy assembly of different functional modules, so that when mounting on the wall elements only the attachment of the units and possibly the connection to the peripheral components is necessary. The structure according to the invention allows a complete integration of all units in the mounting element, so that any interference with the planar plane of a wall element is avoided and the sound-absorbing parameters are not changed.

The mounting elements are produced in excess lengths and kept in stock, with an extensive pre-assembly of units is possible. During final assembly to the wall elements, the mounting elements are shortened to the required length. Since the units are essentially not at the ends, a shortening is also unproblematic in the assembled state. As a result, there are a few standard elements to be produced which can be adapted to a large number of dimensions and installation variants.

Each functional module has a profiled, elongated mounting element into which the individual components are integrated. By doing Mounting element opposite guide grooves are formed, in which the components are inserted uniformly. For this purpose, the components each have a base plate which is guided displaceably in the grooves and thus can also be flexibly positioned in the longitudinal direction. Depending on the design, several components can be arranged on a base plate. If mechanical or electrical connections to the running rail or adjacent wall elements are necessary, allow correspondingly flexible and variable connections a simple and subsequent adjustment.

In the embodiment as a sealing module, a functional module on a sealing strip, a mechanical lifting mechanism, a drive and a power supply unit and carriage attachments. Further optional components are possible. The structural design of the components and their interaction is possible in many ways.

Advantageously, the activation of the sealing module via an electrically driven motor. The motor is also arranged in the sealing module, wherein the motor movement is transmitted to the sealing strip via different deflection mechanisms. The power supply and control of the engine can be done in different ways. There are contactless and contact or line-bound systems possible. Leadless systems use energy storage in the form of rechargeable batteries, which must be temporarily recharged or replaced. A contact-bound variant allows a supply via sliding contacts in the running rail of the partition wall system. Furthermore, it is possible to supply the sealing modules electrically via plug connections on the longitudinal edges of the wall elements. It is only in the case of the final positioning of all wall elements in the contacting of all connectors energy from a stationary source at. Each motor can be supplied directly or with the interposition of an energy storage device.

Basically, for emergencies, especially in case of power failure, always a mechanical actuation of the sealing modules possible. However, this function can also be present as a standard operation or alternative variant, so that a semi-automatic system is created. Preferably, then, a mechanical connection of the upper and lower sealing module, so that a synchronous actuation of both sealing strips takes place with an operation.

The deflection of the rotary motor movement in a translational lifting / lowering movement for the sealing strip via gear arrangements, preferably via a cable or a spindle, which ultimately move the sealing strip. Here, depending on the requirement, the sealing strip can be retracted by a motor or extended by a motor.

In particular, when using a spindle, both the motor, the spindle and a lever connected to the sealing strip are arranged on a base plate and constitute an assembly unit. The spindle can be used as a compact unit or in conjunction with a linkage scissors. The arrangement of the spindle and the motor can be done either one behind the other or one above the other. In the series arrangement, the overall height of the mounting unit is reduced. The mechanical connection with the sealing strip takes place by means of the lever. In addition, support bolts of the carriage act as a guide, these support bolts are also positioned by means of base plates in the base body of the sealing module. The sealing strip is hereby both motorized and extended.

In the version with a cable exists a base plate with the motor and the pulley. Furthermore, there are two support pin elements with separate base plates on which additionally spring-loaded with the sealing strip spring tables are mounted. On both sides of the pulley outgoing ropes are connected to the spring tables and actively pull the preloaded sealing strip with motor actuation.

The sealing strip is non-positively attached to corresponding devices of the lever mechanisms and slides positively in the rail-like mounting element. This results in a low-friction guidance in the process, at the same time reduces the ingress of dirt and running noise can be reduced. At the edges sealing rubber lips are additionally arranged.

At the top of the sealing strips are elongated holes through the support bolts of the carriage occur. The eccentric arrangement of the slots or the support pin prevents tilting of the sealing strip in the process. Due to the formation of elongated holes and the position of the carriage can be varied.

In addition to the horizontal conclusion of the wall elements can be with such sealing mechanisms according to the same principle, the vertical edges, in particular on wall end elements, seal.

The mounting elements are arranged on the edge side either within a recess concealed in the wall element or building on the respective edge of the wall element. Due to the arrangement in a recess, the mounting element is completely invisible. In the constructive embodiment, the positioning and attachment takes place without forming a recess. Particularly advantageous are form-fitting cooperating contours between the mounting member and the Recess or the edge, since in addition to the attachment described below, an additional anchoring of the mounting elements takes place.

The attachment of the mounting elements is preferably integrated into the layer-forming structure of the wall elements, since on the one hand the creation of a core of the wall element to form a recess and on the other hand, the bonding of the layers is used simultaneously for fastening the mounting elements and no separate process steps are necessary. If necessary, corresponding recesses can also be milled into the plate at the installation site and the mounting elements can be mounted therein or the mounting elements can be attached constructively.

Preferably, mounting elements are used in the form of profiles, as this exactly defined and dimensionally stable mounting spaces are created. The profiles are adapted to the shape of the recess or the shape of the edge and preferably formed U-shaped or H-shaped. On the inside, the profiles have various channels, chambers and holes in order to position and fix the various units. Overall, a uniform preferably circumferential mounting area is created by the profiles, so that modular units can be arranged at any point.

Overall, the manufacturing and assembly costs are significantly reduced, since no individual mounting solutions must be created and mainly system components are used. In particular, the manual manufacturing steps are significantly reduced, since a large part can be automated. The wall element can also be sent as a kit. Final cutting measures of the plate, in particular for the attachments, and their final assembly are also possible at the installation site.

To realize, for example, a functional exterior finish of rooms or buildings with regard to acceptable heat, sound and / or fire insulation in the floor and ceiling area, sealing elements are used on the top and bottom of each wall element horizontally, which seal against the running rail or against the ground , Even slight bumps can be compensated by such sealing modules. The extension and retraction takes place via a mechanism that is put into operation via an automatically or manually controllable drive unit. Preferably horizontally arranged mounting elements made of metal, since heavy and in particular load-bearing units are arranged here.

The vertical edge regions of each wall element are formed profiled at least in sections, in order to obtain a positive connection to the edge regions of adjacent wall elements. In particular, at the vertical edges mounting elements are arranged for this, in which sealing profiles or moldings are mounted, which cooperate with a complementary designed edge region of the adjacent wall element and create a soundproof and stable connection. Preferably, vertically arranged mounting elements made of plastic, as a result of material due to a sound decoupling is realized.

The selection of the materials of a wall element and their stratification is carried out in particular under weight-specific and acoustic aspects, wherein the outer layers are additionally selected from optical and practical points of view. A complex production of a load-bearing frame construction is eliminated, since only the blank and the connection of the layers is required to provide the basic construction for a wall element.

The various layer materials are stocked in sheet form and cut to the required size as needed. Preferably, in this case a dimensioning with a grid dimension is advantageous in order to realize different dimensions efficiently. The creation of the basic construction of the wall element is carried out by layering the plates and supplying adhesive and filling compounds. Due to the variable selection and arrangement of the layers and filling materials, customer-specific requirements can be dealt with quickly and easily at any time.

A wall element according to the construction according to the invention has a core which is clad on both sides by an outer shell. The outer shell is preferably multi-layered and consists of an outer cover layer, a middle layer and an inner layer. The two outer shells are formed overall heavy and soundproof and are separated by the preferably soft core material acoustically. Due to the full-surface connection, preferably bonding, all layers and materials of the wall element are combined to form a self-supporting unit. The sound insulation can be realized with reduced effort, as already by the selection of suitable materials and their composite technology, a significant improvement is achieved. In order to improve the rigidity of the wall element while maintaining the sound insulation, the contact surfaces of the layers are formed profiled depending on the material selection.

By selecting different materials, the use of plate-shaped and foamed layers and their connection to a construction in sandwich technique, the individual properties become so advantageously combines that in the sum of a significant improvement is achieved. The wall element has z. B. much higher bending and torsional stiffness than the sum of the properties of separately used layers of the outer shell and core. Such constructed plates also carry considerable loads. Crucial here is the structure of the outer shell and the thickness and density of the core. Compared to a frame construction results in a lower wall thickness and a lower weight with increased stability.

The core material is made of a honeycomb structure, which consists in particular of paper or aluminum. Furthermore, solid material made of polystyrene foam, PU foam, mineral wool, rock wool or the like can be used.

The outer shells are preferably constructed in multiple layers. For the middle layer are metallic materials such. As steel or aluminum sheet, and further plastic (PVC, PC), laminates, glass fiber reinforced plastic (GRP), gypsum, wood, cork, etc .. The inside arranged between the middle layer of the outer shell and the core layer, serves as Shell weight increase and damping material and is preferably made of bitumen. This middle layer also acts as a support for the outer cover layer forming the visible surface. This may be a primer, laminate, laminate or melamine resin. Furthermore, veneers, textile, glass or magnetic surfaces are possible.

Adhesive materials and bonding methods are used to bond the individual layers of the outer shell. As a preferred method, the so-called long-fiber injection method (LFI) is used. In this process, glass fiber strands are cut and simultaneously introduced into a tool with PUR components in a single operation and blended. The finished mixture is then sprayed between the respective layers of the outer shell and creates a permanent bond after curing.

A particularly advantageous construction of the wall element results with a soft core of PUR foam or melamine foam, which is surrounded on both sides by a weight-weighting layer of bitumen. It follows the middle layer of the outer shell, which consists of GRP-coated paper honeycomb with PU foam filling, and have an outer cover layer depending on the customer requirement. Such a material combination has excellent acoustic properties, which forms an optimal solution with regard to the parameters of sound insulation and basis weight.

From such constructed wall elements can be partitions in different configurations create. In particular, a reduction in the load on the hangers and the drive means is created by the significant weight reduction and on the other hand increases the variety of applications by increasing the sound insulation.

The wall elements can be designed as full element, passage door, angle element, window element, compensating element, rotary wing, pendulum wing or moving automatic doors. All wall elements can be moved out of the partition wall axis and parked in a fixed place to save space. Each wall element can be moved at one or two points by means of carriages in a track rail mounted on the ceiling side.

The entire partition fulfills the conditions of the heat protection ordinance, so that even at low outside temperatures there are no energetic and therefore cost-intensive disadvantages.

The invention will now be explained with reference to embodiments with the aid of the drawings.

The same or equivalent components are designated in the figures with the same reference numerals.

A mobile partition is made up of several tabular independently movable, hanging wall elements 1 assembled and suitable for space division or as an outer closure. The individual wall elements 1 can be moved manually or by motor depending on the design. All wall elements 1 can be moved from a space-saving parking position, a so-called station, in the partition axis and braced there.

For reasons of clarity, a wall element 1 is shown schematically and in excerpts in all figures in order to be able to describe the corresponding structure in a correspondingly detailed form.

In the figures described below wall elements 1 are shown, at the upper horizontal edge each a mounting member 9 is arranged. The mounting member 9 each includes a sealing mechanism 10, which realizes a functional closure of rooms or buildings in terms of acceptable heat, sound and / or fire insulation in the floor and ceiling area. For sealing, the sealing mechanism 10 is pressed out of the mounting element 9 against the running rail or against the ground, wherein in the unactuated state all belonging to the mechanical system units 12 are completely hidden in the respective mounting element 9 are arranged. Even slight bumps can be compensated by the arrangement of these sealing mechanisms 10. The extension and retraction of the sealing mechanisms 10 via an automatically or manually controllable drive unit. On the upper horizontal sides of the wall elements 1 carriages not shown are arranged by means of which the wall elements 1 are movable in a mounted in a building ceiling track rail.

The mounting elements 9 include various units 12, such. B. coupling elements, lifting elements, return organs, drive elements, hangers, floor guides, sealants and electrical equipment. The clamping or the sealing of the wall element 1 serving units 12 are completely arranged in the mounting member 9. As a result, the system is also suitable for use in transparent partitions, since no optical impairments of the appearance arise.

Further mounting elements 9 are inserted or attached to the vertical edges of the wall elements 1 or other suitable locations of the wall element 1. Depending on the use, the mounting elements 9 then include sealing mechanisms 10, separate sealing strips, Power supply elements, service equipment and other system components.

Preferably, mounting elements 9 are used in the form of profiles, as this exactly defined and dimensionally stable mounting spaces are created. The profiles 9 are adapted to the shape of a recess 11 or the shape of the edge and are preferably U-shaped or H-shaped. On the inside, the profiles 9 have various channels, chambers and bores in order to be able to position and fix the various structural units 12. Overall, a uniform, preferably circumferential, mounting area is created by the profiles 9, so that modular units 12 can be arranged at any desired locations.

The modular construction of sealing mechanisms 10 greatly simplifies manufacture and assembly and will be described with reference to the following figures. The sealing mechanism 10 is arranged interchangeable and expandable in the mounting element 9 modular manner by means of a uniform assembly and fastening technology. The mounting element 9 is arranged concealed on an upper horizontal edge of a wall element 1 in an incorporated recess 11. The attachment of the mounting element 9 takes place either in the production of the wall element 1 by a positive connection or subsequently in the context of an adhesive process.

The various assemblies 12 are laterally inserted into the mounting member 9, wherein grooves 18 allow flexible positioning in the longitudinal direction. The units 12 each have a base plate 19 which is slidably guided in the mutual grooves 18 and preferably secured by means of a screw, not shown. The complete sealing mechanism 10 has a sealing strip 20, a lifting mechanism 21 and a motor drive 22 and carriage fasteners 23.

According to FIGS. 2 to 4 Both the motor 22, the lifting mechanism 21 in the form of a spindle unit 24 and a lever 25 connected to the sealing strip 20 are arranged on a common base plate 19 and constitute an assembly unit, while support bolts 23 for the carriages each have separate base plates 19. The motor 22 is located above the base plate 19, while below the base plate 19, a mechanical spindle unit 24 is arranged, which acts on the likewise arranged on this base plate 19 lever 25, which ultimately actuates the sealing strip 20. An output shaft of the motor 22 is connected via a toothed belt 26 with a shaft of the spindle unit 24.

The spindle unit 24 consists of the spindle 27, which is rotatably mounted in a screw housing 28. The screw housing 28 is slidably mounted on the underside of the base plate 19, wherein a guided through a slot 29 of the base plate 19 screw 30 holds the screw housing 28. At the front of the base plate 19, a T-shaped lever 25 is rotatably mounted, which is connected on the one hand with the sealing strip 20 and on the other hand with the spindle unit 27. In this case, on both sides of the screw housing 28 arms 31 are arranged, which establish the connection to the lever 25 and allow in addition to the horizontal and a slightly rotational movement. The other end of the lever 25 is thereby moved vertically and moves the sealing strip 20 against the running rail. The attachment of the sealing strip 20 to the lever 25 via a rotatably mounted on the lever 25 plunger 32, wherein the positioning of the sealing strip 20 in the plunger 32 can be adjusted by a thread. The eccentrically arranged support pin 23 of the carriage serve the sealing strip 20 as an additional guide. The sealing strip 20 is both motor on and extended.

According to Figure 5 to 7 another embodiment of a spindle drive 24 is shown. Again, the motor 22, the lifting mechanism 21 in the form of a spindle 27 and a lever 20 connected to the lever 25 are arranged on a common base plate 19 and constitute an assembly unit, while support bolts 23 each have separate base plates 19 for the carriage. The motor 22 and the spindle unit 24 are arranged in series in a row and connected by gearing. Both units are surrounded by a base plate 19, which is either arranged integrally on one of the two units or is fastened separately.

The spindle unit 24 consists of the spindle 27, which is rotatably mounted in a screw housing 28. The screw housing 28 is attached centrally to the base plate 19. On the screw housing 28, a toggle lever 25 is rotatably mounted on the outside, which is connected on the one hand with the sealing strip 20 and on the other hand with the spindle 27. In this case, on both sides of the screw housing 28 arms 31 are arranged, which establish the connection to the lever 25 and allow in addition to the horizontal and a slightly rotational movement. The other end of the lever 25 is thereby moved vertically and moves the sealing strip 20 against the running rail. The attachment of the sealing strip 20 to the lever 25 via a rotatably mounted on the lever 25 plunger 32, wherein the positioning of the sealing strip 20 in the plunger 32 can be adjusted by a thread. The eccentrically arranged support pin 23 of the carriage serve the sealing strip 20 as an additional guide. The sealing strip 20 is both motor on and extended.

In a further embodiment according to FIG. 8 a spindle unit 24 is again arranged in series with the drive motor 22. The spindle unit 24 consists of a linkage scissors 33, wherein by the method of the spindle 27 located between each end of the spindle 27 Nuts 34 a spring-loaded articulated scissors 33 is moved up and down.

In the execution according to the FIG. 9 and 10 the lifting mechanism 21 is realized by means of a cable 35. In this case, there is a base plate 19 with a drive 22 and a pulley 36. Furthermore, there are two separate support pin elements 23 each having a base plate 19. On each of these base plates 19 each a pulley 37 is arranged and additionally a spring-mounted and coaxial about the support pin 23rd arranged table 38 present, which is coupled to the sealing strip 20. A side emerging from the drive 22 output shaft is coupled directly to the axis of the pulley 36. From the pulley 36 on both sides outgoing ropes 35 act on the pulleys 37 on the tables 38 and thus the sealing strip 20. Since the sealing strip 20 is located by the suspension in the extended state, the ropes 35 are rolled up upon activation of the motor 22 and thus the biased Sealing strip 20 retracted during motor operation.

The sealing strip 20 is non-positively connected to the lever 25 (FIG. FIGS. 2 to 8 ) or the spring tables 38 ( FIG. 9 and 10 ) and slides positively in the rail-like mounting element 9. This results in a good leadership in the process, while reducing the ingress of dirt and noise is reduced. At the upper edges sealing rubber lips 39 are additionally arranged. At the ends of the sealing strips 20 pass slots through which the support pins 23 of the carriage occur. The eccentric arrangement of the support pin 23 prevents tilting of the sealing strip 20 in the process. Due to the excess length of the slots and the position of the carriage can be varied.

The activation of the sealing module via a drive 22 in the form of an electric motor, preferably a DC motor. The energy supply and control of the motor 22 can be done in a variety of ways, the following briefly by hand the FIGS. 11 to 14 be explained, with the respective function modules are supplied separately or jointly.

There are contactless and contact or line-bound systems possible. When using contactless systems energy storage 40 are used in the form of accumulators that can be temporarily recharged or replaced. The energy or data transfer 41 is contactless, wherein the energy and data are converted and processed in an electrical unit 42. Such an embodiment is the FIG. 11 shown.

A contact-bound variant allows a supply via sliding contacts 43, which are arranged in the running rail of the partition wall system ( FIG. 12 ).

Furthermore, it is possible to electrically supply the sealing modules via plug connections 44 on the longitudinal edges of the wall elements 1. In this case, only in the case of the final positioning of all wall elements 1 contacting by the adjacent wall elements, since only then a connection of the plug contacts 44 exists. In this case, the motor 22 can be supplied directly or with the interposition of an energy store 40 ( FIG. 13 . FIG. 14 ).

Basically, for emergencies, especially in case of power failure, always a mechanical actuation of the sealing modules possible. However, this function can also be present as a standard operation or alternative variant, so that a semi-automatic system is created. For this purpose, a mechanical connection of the upper and lower sealing module is present, so that a synchronous operation of both sealing strips with an operation by, for example, a crank takes place.

In addition to the horizontal conclusion of the wall elements 1 with the sealing strips, of course, according to the same principle, the vertical edges, in particular seal on end elements.

In the FIG. 15 the layer structure of a wall element 1 is shown. The wall element 1 consists in the embodiment of a core 2 and arranged on both sides outer shells 3, 4. It thus results in a mirror image structure. The outer shells 3, 4 are formed heavy and soundproof and are separated acoustically by a preferably soft core material. Through a full-surface bonding the outer shells 3, 4 and the core 2 are combined to form a self-supporting unit.

The core 2 is made of a honeycomb structure, which consists in particular of aluminum or paper. Further, solid material of polystyrene foam, PU foam, mineral wool, rock wool or the like can be used.

Both outer shells 3, 4 are constructed in multiple layers and each consist on the inside of a weight-weighting and sound-insulating layer 301, 401, a middle layer 302, 402 of honeycomb material and an outer cover layer 303, 403. The layers are bonded together by means of LFI entry.

For the middle layers 302 and 402 are suitable metallic materials such. As steel or aluminum sheet, and further plastic (PVC, PC), laminates (GRP), gypsum, wood, cork, etc .. The layers 302 and 402 act as a support for the visible outer layers 303 and 403. Their surface may consist of primer, laminate, laminate or melamine resin. Furthermore, veneers, textile or glass surfaces are possible.

A particularly advantageous construction of the wall element 1 results with a soft core of PUR integral foam or melamine foam. The mass is preferably 25-75 kg / m ³ with a thickness of 40 to 80 mm. The basis weight is preferably 10 to 40 kg / m ² . On both sides, a weight-weighting layer 301, 401 of bitumen is arranged, which is about 5 - 8 mm thick and has a basis weight of about 5 - 15 kg / m ² . The following middle layer 302, 402 consists of GFK-coated paper honeycomb with PU foam filling. Finally, the outer cover layer 303, 403 is applied on both sides, which is about 1 - 4 mm thick. Such a material combination has excellent acoustic properties, which forms an optimum solution with regard to the parameters of sound insulation and basis weight, so that a sound insulation value of about 55 dB is achieved.
