Abstract

The invention provides a plurality of wall elements (1) which can be fitted together to form a mobile partitioning wall. For sound insulation and fixing the wall elements between ceiling and floor, a ceiling seal moulding (8) and a floor seal moulding (9) are provided. These interact with a pneumatic lifting member (20) via a linkage (16, 16'). The lifting member (20) contains a bellows. Compressed-air coupling valves are provided on both narrow sides of the wall element (1). When wall elements (1) are fitted together, the coupling valves are opened for the throughflow of compressed air, and thus for the actuation of the lifting member (20). <IMAGE>

Description

Die Erfindung bezieht sich auf eine mobile Trennwand mit an Laufschienen aufgehängten Wandelementen und mit mindestens einer jedem Wandelement zugeordneten Dichtleiste gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a mobile partition wall with wall elements suspended from running rails and with at least one sealing strip assigned to each wall element according to the preamble of claim 1.

Derartige Trennwände dienen zur wahlweisen Raumunterteilung. Die einzelnen Wandelemente sind verfahrbar an Laufschienen an der Decke aufgehängt und lassen sich im Nichtgebrauchszustand auf engen Raum zusammenschieben. Damit eine leichte Verschiebbarkeit der einzelnen Wandelemente gewährleistet ist, bedingt dies einen Bodenspalt und einen Deckenspalt. Nachteilig ist indessen, dass die Schalldämpfung als Folge des Boden- und Deckenspaltes unbefriedigend sind und üblicherweise eine Nut in einer Bodenführungsschiene vorhanden sein muss um die notwendige Standfestigkeit der Wandelemente zu erreichen.Such partitions are used for optional room division. The individual wall elements can be moved and suspended from rails on the ceiling and can be pushed together in a confined space when not in use. So that the individual wall elements can be easily moved, this requires a floor gap and a ceiling gap. However, it is disadvantageous that the sound absorption as a result of the floor and ceiling gap is unsatisfactory and that there is usually a groove in a floor guide rail in order to achieve the necessary stability of the wall elements.

Es ist zwar bereits bekannt (wie z.B. in WO-A-8 300 182 beschrieben) den einzelnen Wandelementen zugeordnete Dichtschienen mechanisch anzupressen. Dies wird indessen als umständlich empfunden, namentlich wenn die Raumunterteilung häufig geändert wird.It is already known (as described, for example, in WO-A-8 300 182) to mechanically press on sealing rails assigned to the individual wall elements. However, this is perceived as cumbersome, especially if the room division is changed frequently.

Mit der Erfindung soll die Aufgabe gelöst werden, bei mobilen Trennwänden einerseits eine gute Schalldichtung und andererseits eine hohe Standfestigkeit der einzelnen Wandelemente unter Vermeidung einer Bodenführungsschiene zu erreichen, wobei die Verspannung auch bei schweren und hohen Wandelementen einfach und rasch durchführbar sein soll.The object of the invention is to achieve good soundproofing on the one hand and high stability of the individual wall elements on the one hand in mobile partition walls while avoiding a floor guide rail, wherein the bracing should be easy and quick to carry out even with heavy and high wall elements.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Dadurch ist es möglich, die Wandelemente entlang den Laufschienen leicht gängig zu verschieben und durch Aktivierung der den Wandelementen zugeordneten pneumatischen Huborganen eine gute Standfestigkeit und hohe Schalldämmung zu erreichen. Ausserdem lassen sich die Huborgane von einer gemeinsamen Druckluftquelle mühelos allein durch Aneinanderfügen der Wandelemente aktivieren.This makes it possible to move the wall elements easily along the running rails and to achieve good stability and high sound insulation by activating the pneumatic lifting elements assigned to the wall elements. In addition, the lifting elements can be easily activated from a common compressed air source simply by joining the wall elements together.

Die Trennwand enthält mehrere voneinander unabhängige, tafelförmige Wandelemente 1. Jedes dieser Wandelemente 1 ist an einer Laufschiene aufgehängt, welche an der Gebäudedecke befestigt ist. Im Innern der als Hohlprofil ausgebildeten Laufschiene 2 befinden sich zwei Laufwagen mit Rollen 3 oder Kugeln, die über ein Gehänge 4 mit horizontalen Querträgern 5 des Wandelementes 1 verbunden sind. Das Wandelement 1 enthält eine Rahmenkonstruktion aus Holz oder Metall, insbesondere Stahl und/oder Aluminium, mit zwei im Abstand voneinander angeordneten Platten 6, die aus unterschiedlichen Materialien bestehen können, beispielsweise Stahl, Aluminium, Glas, Gips, Holz oder Kunststoff. Die Platten 6 können auch in Sandwich-Konstruktion ausgeführt werden. Es ist ferner möglich, das Wandelement 1 als Stahlrahmenkonstruktion mit Verglasung auszubilden.The partition wall contains a plurality of mutually independent, tabular wall elements 1. Each of these wall elements 1 is suspended from a running rail which is fastened to the ceiling of the building. Inside the running rail 2, which is designed as a hollow profile, there are two carriages with rollers 3 or balls, which are connected via a hanger 4 to horizontal cross members 5 of the wall element 1. The wall element 1 contains a frame construction made of wood or metal, in particular steel and / or aluminum, with two plates 6 arranged at a distance from one another, which can consist of different materials, for example steel, aluminum, glass, plaster, wood or plastic. The plates 6 can also be designed in a sandwich construction. It is also possible to design the wall element 1 as a steel frame construction with glazing.

Im Zwischenraum 7 zwischen den beiden Platten 6 befindet sich oben eine Deckendichtleiste 8 und unten eine Bodendichtleiste 9, die beiden höhenbeweglich sind. An den beiden vertikalen Schmalseiten der Wandelemente 1 ist je eine Profilschiene 10 vorhanden.In the space 7 between the two plates 6 there is a ceiling sealing strip 8 at the top and a floor sealing strip 9 at the bottom, both of which are movable in height. A profile rail 10 is provided on each of the two vertical narrow sides of the wall elements 1.

Die Deckendichtleiste 8 ist oben mit flexiblen Dichtstreifen 11 versehen, die dazu bestimmt sind, gegen die Laufschiene 2 angedrückt zu werden. Entsprechende flexible Dichtstreifen 12 sind auch an der Bodendichtleiste 9 vorhanden und dazu bestimmt, gegen den Boden 14 angedrückt zu werden. Die beiden Dichtleisten 8 und 9 sind durch ein Gestänge mit den beiden Stangen 16, 16' unter Zwischenschaltung eines Huborganes 20 verbunden. Zwischen den Dichtleisten 8, 9 und dem pneumatischen Huborgan 20 befinden sich Druckfedern 18, welche die Stangen 16, 16' umgeben. Diese Druckfedern 18 liegen einerseits gegen die beiden mit den Platten starr verbundenen Längsträgern 5 und andererseits gegen je einen Anschlag 19 der Stangen 16, 16' an, vorzugsweise in Form einer Scheibe oder eines Querstiftes. Die beiden Druckfedern 18 sind im Ruhezustand leicht vorgespannt und haben das Bestreben die beiden Dichtleisten 8, 9 je in ihre nicht-dichtende Lage zu ziehen.The ceiling sealing strip 8 is provided at the top with flexible sealing strips 11, which are intended to be pressed against the running rail 2. Corresponding flexible sealing strips 12 are also present on the floor sealing strip 9 and are intended to be pressed against the floor 14. The two sealing strips 8 and 9 are connected by a linkage to the two rods 16, 16 'with the interposition of a lifting element 20. Between the sealing strips 8, 9 and the pneumatic lifting element 20 there are compression springs 18 which surround the rods 16, 16 '. These compression springs 18 lie on the one hand against the two longitudinal beams 5 rigidly connected to the plates and on the other hand against one stop 19 of the rods 16, 16 ', preferably in the form of a disk or a transverse pin. The two compression springs 18 are slightly pretensioned in the idle state and endeavor to pull the two sealing strips 8, 9 into their non-sealing position.

Das im Zwischenraum 7 angeordnete, pneumatisch betätigbare Huborgan 20 ist in Vertikalrichtung bewegungswirksam und dazu bestimmt eine Druckkraft auf die beiden Dichtleisten 8, 9 auszuüben. Das Huborgan 20 ist im Hohlraum 7 gestützt.The pneumatically actuated lifting element 20 arranged in the intermediate space 7 is effective in the vertical direction and is intended to exert a compressive force on the two sealing strips 8, 9. The lifting member 20 is supported in the cavity 7.

Wie aus Fig. 3 ersichtlich ist, enthält das Huborgan 20 einen Faltenbalg 22 mit vertikalem Bewegungsweg. Der Faltenbalg 22 ist von einem becherartigem Gehäuse 24 umgeben. Gegen eine beweglich gehaltene Stützscheibe 26 am unteren Ende des Faltenbalges 29 liegt ein U-förmiger Bügel 28 an, der mit der unteren Stange 16 verbunden ist. Ein Schlauch 23 oder eine Rohrleitung mündet in das Innere des Faltenbalges 22 ein. Wie aus Fig. 1 hervorgeht, ist dieser Schlauch 23 Teil einer Druckluftleitung 36, die mit pneumatischen Kupplungsventilen 30, 32 in Verbindung steht. Diese Kupplungsventile 30, 32 sind an sich gegenüberliegenden vertikalen Schmalseiten der Wandelemente 1 befestigt und zum gegenseitigen Zusammenwirken bestimmt, wie dies nachfolgend im Zusammenhang mit den Fig. 4 und 5 näher erläutert wird. Das erste Kupplungsstück 30 ist in an sich bekannter Weise als Rückschlagventil ausgebildet und enthält einen vorstehenden Stift 38, der beim Zusammenwirken mit dem zweiten Kupplungsstück 32 den Durchfluss für die Druckluft öffnet und umgekehrt beim Trennen den Durchfluss unterbricht.As can be seen from FIG. 3, the lifting element 20 contains a bellows 22 with a vertical movement path. The bellows 22 is surrounded by a cup-like housing 24. A U-shaped bracket 28, which is connected to the lower rod 16, bears against a movably held support disk 26 at the lower end of the bellows 29. A hose 23 or a pipe opens into the interior of the bellows 22. As can be seen from FIG. 1, this hose 23 is part of a compressed air line 36 which is connected to pneumatic clutch valves 30, 32. These coupling valves 30, 32 are fastened to opposite vertical narrow sides of the wall elements 1 and are intended for mutual interaction, as will be explained in more detail below in connection with FIGS. 4 and 5. The first coupling piece 30 is designed in a manner known per se as a check valve and contains a projecting pin 38 which, when interacting with the second coupling piece 32, opens the flow for the compressed air and, conversely, interrupts the flow when it is separated.

Das erste Kupplungsstück 30 ist an einer Tragschiene 40 durch Schrauben 42 befestigt. An der Tragschiene 40 ist ein Dichtungskonus 44 aus elastischem Material festgemacht, der den Ventilkörper 46 umgibt. Ein linear bewegliches Ventilglied 50 bewirkt beim Zusammenwirken mit dem Gegenstück ein Öffnen des Durchflusses für die Druckluft. Mit der Druckluftöffnung 52 ist die Schlauch- oder Rohrleitung 36 verbunden.The first coupling piece 30 is fastened to a mounting rail 40 by screws 42. A sealing cone 44 made of elastic material, which surrounds the valve body 46, is fastened to the mounting rail 40. A linearly movable valve member 50, when interacting with the counterpart, opens the flow for the compressed air. The hose or pipeline 36 is connected to the compressed air opening 52.

Das zweite Kupplungsstück 32 enthält eine nachgiebige Hülle 56, vorzugsweise aus einem Elastomer, die von der metallischen Vertikalschiene 10 gehalten ist. Im Zentrum befindet sich ein durch eine Feder 62 abgestützter Bolzen 58. Die Feder 62 wird in einem Support 64 abgestützt und ist bestrebt den Bolzen 58 mittels einer Ringscheibe 68 nach oben zu drücken. Die zentrale Bohrung 66 des Bolzens 58 mündet in die Schlauch- oder Rohrleitung 36 ein. Beim Zusammenschieben zweier benachbarter Wandelemente 1 dringt das Ventilglied 58 in das Ventilglied 50 ein und bewirkt eine dichte Verbindung. Dabei wird der federnde Bolzen 58 entgegen der Federkraft eingedrückt. Die Druckluft strömt somit über den hohlen Stift 38 in die Bohrung 66 des Bolzens 58 zum Huborgan 20. Bei einer Trennung der beiden Wandelemente 1 bewirkt das Rückschlagventil im ersten Kupplungsteil 30 einen Unterbruch des Druckluftdurchganges.The second coupling piece 32 contains a resilient sleeve 56, preferably made of an elastomer, which is held by the metallic vertical rail 10. In the center is a bolt 58 supported by a spring 62. The spring 62 is supported in a support 64 and strives to push the bolt 58 upwards by means of an annular disk 68. The central bore 66 of the bolt 58 opens into the hose or pipeline 36. When two adjacent wall elements 1 are pushed together, the valve member 58 penetrates into the valve member 50 and effects a tight connection. The resilient pin 58 is pressed in against the spring force. The compressed air thus flows via the hollow pin 38 into the bore 66 of the pin 58 to the lifting element 20. When the two wall elements 1 are separated, the check valve in the first coupling part 30 interrupts the compressed air passage.

Gemäss Fig. 1 ist an mindestens einem Wandelement ein von Hand betätigbares Dekompressionsventil 34 vorhanden, das bewirkt, dass bei einer Betätigung die Druckluft aus dem Faltenbalg 22 entweicht. Nach der Dekompression heben die beiden Druckfedern 18 die Dichtleisten 8, 9 vom Boden 14 bzw. von der Laufschiene 2 ab.1, a manually operable decompression valve 34 is provided on at least one wall element, which causes the compressed air to escape from the bellows 22 when actuated. After decompression, the two compression springs 18 lift the sealing strips 8, 9 from the base 14 or from the running rail 2.

An einer vertikalen Gebäudewand befindet sich eine Wandanschlussleiste mit einem pneumatischen Zapfventil, das mit einer üblicherweise ortsfesten Druckluftquelle in Verbindung steht. Ein Druckluftkompressor kann sich an irgend einer Stelle des Gebäudes oder beispielsweise in einer Decken-Nische befinden und steht mit dem Zapfventil in Durchflussverbindung. Der vom Kompressor aufzubauende Druck beträgt vorzugsweise etwa 3-6 bar.On a vertical building wall there is a wall connection strip with a pneumatic nozzle, which is connected to a usually stationary compressed air source. An air compressor can be located anywhere in the building or in a ceiling niche, for example, and is in flow connection with the nozzle. The pressure to be built up by the compressor is preferably approximately 3-6 bar.

Zum Aufbau einer Trennwand wird vorerst ein erstes Wandelement 1 auf der Laufschiene 2 gleitend gegen eine stationäre Wandanschlussleiste zum Anliegen gebracht und öffnet dabei das zugehörige Zapfventil, sodass Druckluft in Richtung des Pfeiles C in die Leitung 36 einströmen kann. Dadurch füllt sich der Faltenbalg 22 mit Druckluft und bewegt die Stangen 16, 16' nach entgegengesetzten Richtungen, nämlich in die Richtungen A und B in Fig. 3. Als Folge davon werden die beiden Dichtleisten 8 und 9 in ihre Dichtposition gebracht und die Lage des Wandelementes 1 zwischen Boden 14 und Decke fixiert. Hernach wird ein weiteres Wandelement 1 an das erste angefügt werden, wobei durch das Zusammenfügen die miteinander zusammenwirkenden Kupplungsteile 30, 32 den Druckluft-Durchfluss öffnen und dadurch ein Druckaufbau im Huborgan 30 dieses benachbarten Wandelementes bewirken wird, was ebenfalls zur Anhebung der betreffenden Deckendichtleiste 8 und zum Absenken der Bodendichtleiste 9 führt.To build a partition, a first wall element 1 is first brought into sliding contact with the running rail 2 against a stationary wall connection strip and thereby opens the associated nozzle valve, so that compressed air can flow into the line 36 in the direction of arrow C. As a result, the bellows 22 fills with compressed air and moves the rods 16, 16 'in the opposite direction Directions, namely in directions A and B in Fig. 3. As a result, the two sealing strips 8 and 9 are brought into their sealing position and the position of the wall element 1 between the floor 14 and ceiling fixed. Subsequently, a further wall element 1 will be added to the first one, whereby the coupling parts 30, 32, which interact with one another, open the compressed air flow and thereby cause a pressure build-up in the lifting element 30 of this adjacent wall element, which likewise increases the relevant ceiling sealing strip 8 and leads to the lowering of the floor sealing strip 9.

Beim Anfügen weiterer Wandelemente 1 wiederholt sich der beschriebene Vorgang. Dadurch brauchen die Wandelemente nicht einzeln mit einer mobilen Druckluftquelle verbunden zu werden, sondern die Dichtleisten 8, 9 können durch einfaches Aneinanderschieben der Wandelemente 1 in die Dichtlage gebracht werden. Nach dem Zusammenfügen der Wandelemente sind sie unabhängig von einem Kompressor oder anderen Druckluftquellen. Bei Druckverlust eines beliebigen Wandelementes bleiben die übrigen Wandelemente infolge des Rückschlagventiles unter Druck.The process described is repeated when additional wall elements 1 are added. As a result, the wall elements do not need to be connected individually to a mobile compressed air source, but the sealing strips 8, 9 can be brought into the sealing position by simply pushing the wall elements 1 together. After assembling the wall elements, they are independent of a compressor or other compressed air sources. If any wall element loses pressure, the remaining wall elements remain under pressure as a result of the check valve.

Zum Entriegeln der Dichtleisten 8, 9 wird ein Dekompressionsventil 34 betätigt, wodurch im Huborgan 20 ein Druckabfall entsteht. Das Wandelement 1 kann hernach entlang der Laufschiene leichtgängig verschoben werden.A decompression valve 34 is actuated to unlock the sealing strips 8, 9, as a result of which a pressure drop occurs in the lifting element 20. The wall element 1 can then be easily moved along the running rail.

Da das Wandelement 1 selbst nicht angehoben werden muss, sondern zur Abdichtung lediglich die beiden Dichtleisten 8, 9 nach oben und nach unten gepresst werden, gelingt es - auch bei schweren Wandelementen - mit einem relativ geringen pneumatischen Druck auszukommen.Since the wall element 1 itself does not have to be raised, but rather only the two sealing strips 8, 9 are pressed upwards and downwards for sealing, it is possible - even with heavy wall elements - to manage with a relatively low pneumatic pressure.

Anstelle eines Faltenbalges 22 könnte auch ein handelsübliches pneumatisches Kolbenzylinderaggregat verwendet werden, um eine vertikale Hubbewegung der Dichtleisten 8, 9 bei Zufuhr von Druckluft zu erreichen.Instead of a bellows 22, a commercially available pneumatic piston-cylinder unit could also be used in order to achieve a vertical lifting movement of the sealing strips 8, 9 when compressed air is supplied.

Eine Ausführungsvariante besteht darin, jeder Dichtleiste 8, 9 einen eigenen Faltenbalg oder ein eigenes Zylinder-Kolbenaggregat mit vertikalem Bewegungsweg zuzuordnen, welche je an die gemeinsame Druckleitung 36 angeschlossen werden.One embodiment variant is to assign each sealing strip 8, 9 its own bellows or its own cylinder-piston unit with a vertical movement path, which are each connected to the common pressure line 36.

Eine weitere Ausführungsvariante besteht darin, dass jedes Wandelement 1 einzeln oder in Gruppen in irgendeiner Position, unabhängig von der Wandanschlussleiste verspannt werden kann. In diesem Fall ist eine entsprechend lange Schlauchleitung oder ein mobiler Druckluftkompressor erforderlich.Another embodiment variant is that each wall element 1 can be braced individually or in groups in any position, regardless of the wall connection strip. In this case, a suitably long hose line or a mobile air compressor is required.

Claims (3)

  1. A mobile partitioning wall having several wall elements (1) suspended on a running rail (2), having sealing strips (9) associated with each wall element, with an upper sealing strip (8), which is height-adjustable in relation to the wall element (1) and can be pressed against the running rail (2), and a lower height-movable sealing strip (9), which is also height-adjustable in relation to the wall element (1) and can be pressed against the floor (14), being provided, the two sealing strips (8, 9) cooperating with at least one displacement device (20) movable in the vertical direction,
    characterised in that the vertical movement of the sealing strips is performed by at least one pneumatically operated lifting device (20) and at the two vertical narrow sides of the wall elements (1) pneumatic coupling valves (30, 32) intended to cooperate are provided, which, when two adjacent wall elements (1) are slid together, are tightly flow-connected with one another and with the at least one lifting device (20) by a compressed air line (36),
    and in that at least one of the coupling valves (30, 32) is constructed as a check valve and a manually-operated decompression valve (34) is provided in the compressed air line (36).
  2. A partitioning wall according to Claim 1,
    characterised in that a two-part rod assembly (16, 16') is situated between the upper and lower sealing strips (8, 9) in the interior of a wall element (1), and cooperates with a common lifting device (20) for moving the rod assembly (16, 16') to opposite sides, and a return spring (18) is associated with each of the two rods (16, 16'), which move the sealing strips (8, 9) into their non-sealing position when the lifting device (20) is unpressurised.
  3. A partitioning wall according to Claim 1 or 2,
    characterised in that the lifting device (20) is a pair of bellows made of elastic material, against the end sides of which the two-part rod assembly abuts (16, 16').
