Abstract
Description
Die Erfindung betrifft ein schienengeführtes Mobilwandelement mit einem Wandkörper, der an seiner Ober- und/oder Unterseite jeweils mindestens ein Dichtelement aufweist, das zwischen einer Verfahrposition und einer Funktionsposition des Mobilwandelements mittels einer motorisch betriebenen Antriebseinheit verstellbar ist.The invention relates to a rail-guided mobile wall element having a wall body which has at least one sealing element on its upper and / or lower side, which is adjustable between a movement position and a functional position of the mobile wall element by means of a motor-driven drive unit.
Ein derartiges Mobilwandelement ist z. B. in
Mehrere Mobilwandelemente der o. g. Art, die üblicherweise in deckenseitig angeordneten Schienen verfahrbar gelagert sind, bilden gemeinsam ein Raumtrennsystem, welches die Erstellung einer Trennwand und somit die variable Raumaufteilung von Hallen, Sälen oder sonstigen Räumen ermöglicht. Zur Abtrennung oder Aufteilung einzelner Räume werden die einzelnen Mobilwandelemente in der gewünschten Position mit ihren Stirnseiten aneinander anliegend aufgereiht. Ausfahrbare Dichtprofile mit Dichtelementen werden gegen die Raumdecke und den Fußboden verschoben und fixieren so die einzelnen Mobilwandelemente. Sie dienen dem Schallschutz und verhindern den Luftaustausch zwischen den durch die Mobilwandelemente abgetrennten Räumen.Several mobile wall elements of o. G. Art, which are usually mounted movably mounted in the ceiling rails, together form a room separation system, which allows the creation of a partition and thus the variable space allocation of halls, halls or other spaces. For the separation or division of individual rooms, the individual mobile wall elements are lined up in the desired position with their front sides adjacent to each other. Retractable sealing profiles with sealing elements are moved against the ceiling and the floor and thus fix the individual mobile wall elements. They serve sound insulation and prevent the exchange of air between the separated by the mobile wall elements spaces.
In der Verfahrposition der Mobilwandelemente, d. h. in der Position, in der diese in ggf. vorhandenen Schienen bewegt und in die zur Raumabtrennung gewünschte Position oder in ihre Lagerposition verbracht werden können, müssen die Dichtelemente derart an dem Wandkörper angeordnet sein, daß sie nicht an der Decke oder dem Fußboden schleifen. Die Dichtelemente befinden sich daher in der Verfahrposition in einer von der Decke und dem Fußboden zurückgezogenen Position. Zur Fixierung der Mobilwandelemente sowie zur oben beschriebenen Abdichtung der abgegrenzten Räume werden die Dichtungen gegen die Decke bzw. den Fußboden gedrückt. Die Endstellung der Dichtprofile, d. h. die Stellung, in der die Dichtprofile vollständig ausgefahren sind, wird als Funktionsposition der Mobilwandelemente bezeichnet.In the traveling position of the mobile wall elements, d. H. in the position in which they can be moved in any existing rails and spent in the desired position for the space separation or in their storage position, the sealing elements must be arranged on the wall body so that they do not grind on the ceiling or the floor. The sealing elements are therefore in the traversing position in a retracted from the ceiling and the floor position. To fix the mobile wall elements and the above-described sealing of the delimited spaces, the seals are pressed against the ceiling or the floor. The end position of the sealing profiles, d. H. the position in which the sealing profiles are fully extended is referred to as the functional position of the mobile wall elements.
Grundsätzlich erfordert der Aufbau einer Trennwand mit bekannten Mobilwandelementen ohne motorischen Antrieb einen hohen Zeitaufwand, da die Dichtprofile dabei manuell mittels einer Kurbel verstellt, d. h. beim Aufbau gegen Decke und Fußboden ausgefahren werden. Der Anpreßdruck, welcher auch für die Stabilität der erstellten Trennwand ausschlaggebend ist, bestimmt sich dabei allein in Abhängigkeit von der Kurbelkraft, d.h. von dem jeweiligen Bedienpersonal. Insbesondere bei großen Räumen, wo sich lange Trennwände ergeben können und eine große Anzahl von Mobilwandelementen eingesetzt werden müssen, ergibt sich ein hoher Zeitaufwand zur Installation einer Trennwand, die aufgrund der manuellen Betätigung überdies unterschiedlich zuverlässig fixiert ist.Basically, the construction of a partition wall requires known mobile wall elements without motor drive a lot of time, since the sealing profiles are manually adjusted by means of a crank, ie extended during construction against the ceiling and floor. The contact pressure, which is also decisive for the stability of the partition created, determined solely as a function of the crank force, ie of the respective operating personnel. In particular, in large rooms, where long partitions may arise and a large number of mobile wall elements must be used, there is a high amount of time to install a partition, which is fixed due to the manual operation also different reliable.
Bei bekannten Mobilwandelementen der eingangs genannten Art, die mit einem zusätzlichen Elektromotorantrieb ausgestattet sind, ist dieser aufgrund seiner Größe in der Mitte des Wandkörpers angeordnet und über eine teure und komplizierte sowie störungsanfällige Antriebsmechanik mit der Ober- und Unterseite des Wandkörpers verbunden. Die Einbringung von Öffnungen, insbesondere Tür- oder Fensteröffnungen in diese Wandelemente, ist nicht möglich. Überdies verhindert die mittig angeordnete Antriebsmechanik eine adäquate Schall- und Wärmeisolierung der Mobilwandelemente.In known mobile wall elements of the type mentioned, which are equipped with an additional electric motor drive, this is located due to its size in the middle of the wall body and connected via an expensive and complicated and fault-prone drive mechanism with the top and bottom of the wall body. The introduction of openings, in particular door or window openings in these wall elements, is not possible. Moreover, the centrally located drive mechanism prevents adequate sound and heat insulation of the mobile wall elements.
Der Erfindung liegt die Aufgabe zugrunde, ein Mobilwandelement mit einem motorisch antreibbaren Dichtelement bereitzustellen, wobei der motorische Antrieb die Gestaltungsmöglichkeiten des Wandkörpers nicht einschränkt.The invention has for its object to provide a mobile wall element with a motor-driven sealing element, wherein the motor drive does not limit the design options of the wall body.
Die Erfindung löst die Aufgabe durch ein schienengeführtes Mobilwandelement mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen wiedergegeben.The invention solves the problem by a rail-guided mobile wall element having the features of
Grundsätzlich besteht die Möglichkeit, die erfindungsgemäßen Mobilwandelemente nur an einer Seite. d.h. in der Einbaulage an der Ober- und Unterseite, mit einem verschiebbaren Dichtelement auszustatten und das gegenüberliegende Dichtelement starr oder gegen eine Federkraft verschiebbar anzuordnen, so daß dort die Abdichtung indirekt über den gegenüberliegenden Antrieb und die dadurch erzeugte Bewegung des Mobilwandelements erzeugt wird. Nachfolgend wird jedoch auf die Ausbildung eines Mobilwandelements mit ober- und unterseitig angeordneten, angetriebenen Dichtelementen ausgegangen. Die Erfindung ist jedoch hierauf nicht beschränkt.In principle, there is the possibility of the inventive mobile wall elements only on one side. ie in the mounting position on the top and bottom, equipped with a sliding sealing element and the opposite sealing element rigid or displaceable against a spring force, so that there the seal is indirectly generated via the opposite drive and the movement of the mobile wall element generated thereby. However, the following is based on the formation of a mobile wall element with upper and lower side, driven sealing elements went out. However, the invention is not limited thereto.
Das erfindungsgemäße Mobilwandelement ist dadurch gekennzeichnet, daß die Antriebseinheit mit dem Dichtelement lösbar in Eingriff bringbar im Bereich der Ober- und/oder Unterseite in stirnseitig an dem Wandkörper angeordneten Aufnahmeöffnungen einschiebbar ist.The mobile wall element according to the invention is characterized in that the drive unit with the sealing element releasably engageable in the region of the top and / or bottom in frontally arranged on the wall body receiving openings can be inserted.
Die erfindungsgemäße Anordnung der Antriebseinheit ermöglicht es, den Wandkörper im Bereich zwischen der Ober- und Unterseite in beliebiger Weise auszugestalten, da dieser frei von Funktionsteilen zur Betätigung des Mobilwandelements bzw. der Dichtelemente ist.The inventive arrangement of the drive unit makes it possible to design the wall body in the region between the top and bottom in any desired manner, since it is free of functional parts for actuating the mobile wall element or the sealing elements.
Darüber hinaus ermöglicht die erfindungsgemäße Ausgestaltung des Mobilwandelements, wonach die Antriebseinheit in den Wandkörper einschiebbar ist und die Zugänglichkeit der Antriebseinheit erhalten bleibt, einen einfachen Ein- und Ausbau der Antriebseinheit. Insbesondere der einfache Ausbau erlaubt es, im Falle des Auftretens von Funktionsstörungen des Mobilwandelements, die aus einer defekten Antriebseinheit resultieren, diese einfach auszutauschen, so daß das Mobilwandelement innerhalb kürzester Zeit wieder einsatzbereit ist. Eine vollständige Demontage des Mobilwandelements, die bei Störungen der Antriebseinheit derzeit bekannter Mobilwandelemente erforderlich ist, entfällt vollständig. Neben der guten Austauschbarkeit defekter Antriebseinheiten ermöglicht der modulare Aufbau des erfindungsgemäßen Mobilwandelements auch dessen einfache und kostengünstige Herstellung.In addition, the inventive design of the mobile wall element, according to which the drive unit can be inserted into the wall body and the accessibility of the drive unit is maintained, allows easy installation and removal of the drive unit. In particular, the simple expansion makes it possible, in the event of malfunction of the mobile wall element, resulting from a defective drive unit, these easily replaced, so that the mobile wall element is ready for use again within a very short time. A complete disassembly of the mobile wall element, which is required in disturbances of the drive unit currently known mobile wall elements, completely eliminated. In addition to the good interchangeability of defective drive units, the modular design of the mobile wall element according to the invention also enables its simple and cost-effective production.
Der Aufbau des Wandkörpers des Mobilwandelements kann grundsätzlich in beliebiger Weise erfolgen. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist der Wandkörper jedoch aus mindestens einem Rahmenelement und beiderseits des Rahmenelements angeordneter Plattenelemente gebildet. Die Verwendung von Rahmenelementen, bspw. verschieden ausgeführter Hohlprofile ermöglicht neben der besonders guten Anordnung der nach außen sichtbaren Plattenelemente auch die besonders einfache Ausgestaltung einer Aufnahmeöffnung für die Antriebseinheit sowie eine besonders einfache Herstellung des Wandkörpers.The structure of the wall body of the mobile wall element can basically be done in any way. According to a particularly advantageous embodiment of the invention, however, the wall body is formed from at least one frame element and arranged on both sides of the frame member plate elements. The use of frame elements, for example. Different executed hollow sections allows not only the particularly good arrangement of the visible to the outside plate elements and the particularly simple design of a receiving opening for the drive unit and a particularly simple production of the wall body.
Aufgrund der im wesentlichen freien Formwahl des Rahmenelements kann dieses darüber hinaus derart ausgestaltet sein, daß es ferner die Montage und Demontage der Dichtelemente der fertig erstellten Mobilwandelemente ermöglicht. Die Montage des Mobilwandelements wird dadurch in ergänzender Weise vereinfacht. Darüber hinaus ermöglicht die Verwendung derartiger Rahmenelemente ggf. auch den besonders einfachen Austausch der Dichtelemente.Due to the substantially free choice of shape of the frame member, this can also be configured such that it also allows the assembly and disassembly of the sealing elements of the finished mobile wall elements. The assembly of the mobile wall element is thereby simplified in a complementary manner. In addition, the use of such frame elements possibly also allows the particularly simple replacement of the sealing elements.
Die Verwendung von Rahmenelementen ermöglicht es ferner, den sich zwischen den Plattenelementen bildenden Hohlraum vollständig mit einem Dämmaterial auszufüllen, so daß die Isolationseigenschaften, insbesondere Schallisolationseigenschaften der unter Verwendung der entsprechend weitergebildeten Mobilwandelemente hergestellten Trennwände gegenüber bekannten Trennwänden deutlich verbessert sind. Die Verwendung eines Dämmaterials zwischen den Plattenelementen ist dabei auch dann möglich, wenn das Mobilwandelement mit verschließbaren Öffnungen, bspw. Fenstern oder Türen versehen ist, die aufgrund der erfindungsgemäßen Ausgestaltung des Mobilwandelements an beliebiger Stelle angeordnet werden können.The use of frame elements also makes it possible to completely fill the cavity forming between the plate elements with an insulating material, so that the insulating properties, in particular sound insulation properties of the partitions produced by using the correspondingly developed mobile wall elements over known partitions are significantly improved. The use of a Dämmaterials between the plate elements is also possible if the mobile wall element is provided with closable openings, for example. Windows or doors that can be arranged at any point due to the inventive design of the mobile wall element.
Die Schienen zur Führung der Mobilwandelemente sowie die entsprechenden Ausgestaltungen der Mobilwandelemente können grundsätzlich beliebig ausgebildet sein. Nach einer vorteilhaften Weiterbildung der Erfindung ist der Wandkörper zur verfahrbaren Lagerung an einer in einer Decke angeordneten Schiene jedoch an seiner Oberseite mit mindestens einem, vorzugsweise zwei Tragelementen verbunden, die besonders vorzugsweise als Laufwagen ausgebildet sind, die drehgelenkig, bspw. über einen Verbindungsbolzen, mit dem Wandkörper verbunden sind. Die Führung der Mobilwandelemente in einer an der Decke angeordneten Schiene ermöglicht es, den Fußboden des Raums, der durch ein Raumtrennsystem mit den erfindungsgemäßen Mobilwandelementen abgetrennt werden kann, ohne Unterbrechungen, bspw. Bodenschienen zur Führung der Mobilwandelemente, auszubilden, die optisch störend wirken würden oder u. U. eine Stolperfalle darstellen könnten. Die Verwendung von Laufwagen weist dabei den Vorteil auf, daß dadurch eine besonders einfache Verschiebbarkeit der Mobilwandelemente in den Deckenschienen erreicht wird. Insbesondere die Lagerung unter Verwendung von zwei Laufwagen gewährleistet eine besonders stabile und sichere Anordnung des Mobilwandelements in der Schiene.The rails for guiding the mobile wall elements and the corresponding embodiments of the mobile wall elements can in principle be of any desired design. According to an advantageous embodiment of the invention, the wall body for movable mounting on a rail arranged in a ceiling, however, at its upper side connected to at least one, preferably two support elements, which are particularly preferably designed as a carriage, the pivotally, for example. Via a connecting bolt, with connected to the wall body. The guidance of the mobile wall elements in a rail arranged on the ceiling makes it possible to form the floor of the room, which can be separated by a room dividing system with the mobile wall elements according to the invention, without interruptions, for example bottom rails for guiding the mobile wall elements, which would have a visually disturbing effect or u. U. could represent a trip hazard. The use of carriages has the advantage that a particularly simple displaceability of the mobile wall elements in the ceiling rails is achieved. In particular, the storage using two carriages ensures a particularly stable and secure arrangement of the mobile wall element in the rail.
Die in den Stirnseiten der Wandkörper angeordneten, erfindungsgemäß besonders gut zugänglichen Aufnahmeöffnungen zur Aufnahme der Antriebseinheiten können grundsätzlich beliebig ausgestaltet sein. So kann die Antriebseinheit auch in einer im Querschnitt lediglich U-förmig ausgebildeten Aufnahmeöffnung, die bspw. durch ein entsprechendes Rahmenelement erreicht wird, angeordnet werden, da aufgrund der Wirkverbindung mit dem Dichtelement ausreichend zuverlässig gewährleistet ist, daß die Antriebseinheit in ihrer Position an dem Mobilwandelement fixiert ist. Nach einer besonderen Weiterbildung der Erfindung weist die Aufnahmeöffnung jedoch Führungen und die Antriebseinheit mit den Führungen in Eingriff bringbare Führungselemente auf. Die Führungen, bspw. schienenartige Längskanäle, die mit als Führungselementen wirkenden Stegen an der Antriebseinheit zusammenwirken, gewährleisten in besonderer Weise sowohl die Positionierung der Antriebseinheit als auch die Lagesicherung der Antriebseinheit im Gebrauch des Mobilwandelements.The arranged in the end faces of the wall body, according to the invention particularly easily accessible receiving openings for receiving the drive units can be configured basically arbitrary. Thus, the drive unit can also be arranged in a U-shaped in cross-section receiving opening, which is for example. By a corresponding frame member, as is ensured due to the operative connection with the sealing element sufficiently reliable that the drive unit in position on the mobile wall element is fixed. According to a particular embodiment of the invention, however, the receiving opening on guides and the drive unit with the guides engageable guide elements. The guides, for example rail-like longitudinal channels, which interact with webs acting as guide elements on the drive unit, ensure in a special way both the positioning of the drive unit and the securing of the position of the drive unit during use of the mobile wall element.
Die Verbindung der Antriebseinheit mit den Dichtelementen kann ebenfalls grundsätzlich beliebig ausgeführt werden. Vorteilhafter Weise ist vorgesehen, daß die Antriebseinheit ein Kupplungselement, vorzugsweise eine hakenförmige Aufnahmeöffnung aufweist, welche mit einem mit einem Dichtprofil verbundenen Steuerelement lösbar in Eingriff bringbar ist, wobei an dem Dichtprofil ein oder mehrere Dichtelemente angeordnet sind.The connection of the drive unit with the sealing elements can also basically be carried out arbitrarily. Advantageously, it is provided that the drive unit has a coupling element, preferably a hook-shaped receiving opening, which is detachably engageable with a connected to a sealing profile control element, wherein one or more sealing elements are arranged on the sealing profile.
Gemäß dieser Weiterbildung der Erfindung ist die Antriebseinheit im vollständig in die Aufnahmeöffnung eingeschobenen Zustand nicht direkt mit den Dichtelementen, sondern über ein in der Regel zentral angeordnetes Steuerelement mit einem Dichtprofil verbunden, das in der Regel zwei parallel zueinander angeordnete, sich über die Breite des Wandkörper erstreckende Dichtelemente aufweist. Das Dichtprofil ist dabei so ausgebildet, daß es die Verbindungsbolzen zur Verbindung des Wandkörpers mit dem Laufwagen umschließt. In der Funktionsposition des Wandkörpers wird die Schiene sowie die darin angeordneten Laufwagen aufgrund der vorteilhafter Weise vorgesehenen Verwendung des Dichtprofils im wesentlichen vollständig verdeckt.According to this embodiment of the invention, the drive unit in the fully inserted into the receiving opening state is not directly connected to the sealing elements, but via a usually centrally arranged control with a sealing profile, which is usually two mutually parallel, over the width of the wall body having extending sealing elements. The sealing profile is designed so that it surrounds the connecting bolt for connecting the wall body with the carriage. In the functional position of the wall body, the rail and the carriage arranged therein is substantially completely obscured due to the advantageously provided use of the sealing profile.
Die Verbindung der Antriebseinheit mit den Dichtelementen über ein zentral an dem Dichtprofil angeordnetes Steuerelement weist darüber hinaus den Vorteil auf, daß einem Verkanten der Dichtelemente bzw. des Dichtprofils wirksam vorgebeugt wird. Auch im Falle einer nicht parallel zur Oberseite des Wandkörpers verlaufenden Bewegung des Dichtprofils von der Verfahrposition in die Funktionsposition stellt sich im Anschluß an eine punktuelle Anlage der Dichtelemente an der Decke bzw. dem Fußboden nach einem weiteren Verfahren eine vollständige Anlage der Dichtelemente an der Decke bzw. dem Fußboden ein.The connection of the drive unit with the sealing elements via a centrally arranged on the sealing profile control also has the advantage that a Tilting the sealing elements or the sealing profile is effectively prevented. Also in the case of a non-parallel to the top of the wall body movement of the sealing profile of the travel position in the functional position is following a punctual contact of the sealing elements on the ceiling or the floor for a further method a complete system of sealing elements on the ceiling or the floor.
Die Funktion des Mobilwandelements ist bereits dann gewährleistet, wenn das Dichtprofil vollständig an der Decke und dem Fußboden anliegt. Gemäß einer vorteilhaften Weiterbildung der Erfindung ist die Antriebseinheit jedoch derart ausgebildet, daß das Dichtprofil mit den daran angeordneten Dichtelementen in der Funktionsposition mittels eines Federelements vorgespannt ist. Die Federvorspannung bewirkt eine besonders zuverlässige Anlage der Dichtelemente an der Decke und dem Fußboden. In Folge der Federvorspannung wird überdies erreicht, daß die Bauteile der Antriebseinheit in der Funktionsposition entlastet sind, so daß diese keiner zerstörerisch wirkenden Dauerbelastung unterliegen.The function of the mobile wall element is already ensured when the sealing profile rests completely on the ceiling and the floor. According to an advantageous embodiment of the invention, however, the drive unit is designed such that the sealing profile is biased with the sealing elements arranged thereon in the functional position by means of a spring element. The spring preload causes a particularly reliable conditioning of the sealing elements on the ceiling and the floor. As a result of the spring bias is also achieved that the components of the drive unit are relieved in the functional position, so that they are not subject to destructive permanent load.
Das Federelement ermöglicht es darüber hinaus, Durchbiegungen der Decke im Bereich des montierten Mobilwandelements aufgrund wechselnder Lasten ohne Verlust der Dichtigkeit auszugleichen. Das Federelement läßt sowohl eine Bewegung der Decke in Richtung auf das Wandelement zu und gleicht zudem Abstandserhöhungen zwischen Decke und Wandelement aus, in dem es die Dichtelemente nachführt. Darüber hinaus wird eine Beschädigung der Funktionsteile der Antriebseinheit in Folge der von der Decke auf die Dichtelemente wirkende Kräfte wirksam ausgeschlossen.The spring element also makes it possible to compensate for deflections of the ceiling in the mounted mobile wall element due to changing loads without loss of tightness. The spring element allows both a movement of the ceiling in the direction of the wall element and also compensates for distance increases between the ceiling and wall element, in which it tracks the sealing elements. In addition, damage to the functional parts of the drive unit as a result of the force acting from the ceiling on the sealing elements forces is effectively excluded.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist die Antriebseinheit eine Vorrichtung zur manuellen Betätigung auf. Diese ermöglicht es, auch im Falle des Ausfalls der Antriebseinheit die Mobilwandelemente zum Aufbau einer Trennwand zu verwenden. Dies kann insbesondere dann erforderlich sein, wenn der Aufbau einer Trennwand erfolgen muß, aber keine Austausch-Antriebseinheit verfügbar ist. Darüber hinaus ermöglicht die manuelle Betätigung auch die Demontage einer Trennwand im Falle des Ausfalls der Antriebseinheit.According to a further advantageous embodiment of the invention, the drive unit has a device for manual actuation. This makes it possible, even in the case of failure of the drive unit to use the mobile wall elements to build a partition. This may be necessary in particular when the construction of a partition wall must be made, but no replacement drive unit is available. In addition, the manual operation also allows the dismantling of a partition in the event of failure of the drive unit.
Nach einer besonders vorteilhaften Ausgestaltung der Antriebseinheit weist diese Endschalter auf. Diese gewährleisten in besonderer Weise, daß die Antriebseinheit nur zwischen den maximal zulässigen Positionen, die der Funktionsposition und der Verfahrposition des Wandelements entsprechen, verstellbar ist.According to a particularly advantageous embodiment of the drive unit, this limit switch on. These ensure in a special way that the drive unit is adjustable only between the maximum permissible positions corresponding to the functional position and the movement position of the wall element.
Die Ausgestaltung der Antriebseinheit kann grundsätzlich in beliebiger Weise erfolgen, sofern sich diese durch Einschieben und Herausziehen in bzw. aus den Aufnahmeöffnungen einfach ein- und ausbauen läßt. Gemäß einer Weiterbildung der Erfindung ist die Antriebseinheit als Hubmodul ausgebildet, welches die Dichtelemente anhebt bzw. absenkt. Die Hubbewegung kann mit beliebigen Antriebselementen, bspw. einer Kolbenzylindereinheit oder dergleichen erzeugt werden. Nach einer Weiterbildung der Erfindung wird die Hubbewegung jedoch durch Umsetzung einer rotatorischen Bewegung in eine translatorische Bewegung erreicht.The configuration of the drive unit can basically be done in any way, provided that it can be easily inserted and removed by inserting and pulling in or out of the receiving openings. According to one embodiment of the invention, the drive unit is designed as a lifting module which raises or lowers the sealing elements. The lifting movement can be generated with any desired drive elements, for example a piston-cylinder unit or the like. According to a development of the invention, however, the lifting movement is achieved by converting a rotational movement into a translatory movement.
Gemäß einer Weiterbildung der Erfindung weist das Hubmodul hierzu eine motorisch angetriebene, beidenends drehbar gelagerte Spindel und eine auf der Spindel angeordnete Rücklaufmutter auf, die durch Verdrehung der Spindel entlang der Spindelachse verschiebbar ist, wobei ein Kniehebel einenendes verschiebbar im Bereich der Rücklaufmutter und anderenendes ortsfest im Bereich eines Spindellagers gelenkig gelagert ist. Der Antrieb der Spindel erfolgt gemäß dieser Weiterbildung der Erfindung vorzugsweise über einen Elektromotor, der die Spindel in Drehung versetzt. In Folge der Drehung der Spindel verkürzt oder verlängert sich - abhängig von der Drehrichtung - der Abstand zwischen der Rücklaufmutter und dem ortsfesten Spindellager, wodurch der Kniehebel gebeugt bzw. gestreckt wird. Zur Erzeugung einer Hubbewegung der Dichtelemente in Richtung auf die Funktionsposition wird der Abstand zwischen der Rücklaufmutter und dem ortsfesten Spindellager verkürzt, wodurch sich der Kniehebel aufstellt. Zur Übertragung der Bewegungen des Kniehebels auf die Dichtelemente ist dieser im Bereich seines Gelenkpunktes mit dem Steuerelement des Dichtprofils verbindbar, so daß die Hubbewegung unmittelbar auf das Steuerelement und die damit verbundenen Dichtelemente übertragen wird.According to one embodiment of the invention, the lifting module for this purpose has a motor-driven, rotatably mounted two-spindle and a spindle arranged on the return nut, which is displaceable by rotation of the spindle along the spindle axis, a toggle one end slidably in the return nut and other stationary in the Spindle bearing is articulated. The drive of the spindle is carried out according to this embodiment of the invention, preferably via an electric motor which causes the spindle in rotation. As a result of the rotation of the spindle, the distance between the return nut and the stationary spindle bearing is shortened or extended, depending on the direction of rotation, whereby the toggle lever is bent or stretched. To generate a lifting movement of the sealing elements in the direction of the functional position, the distance between the return nut and the stationary spindle bearing is shortened, whereby the toggle lever sets up. To transmit the movements of the toggle lever on the sealing elements of this is in the region of its hinge point connected to the control of the sealing profile, so that the lifting movement is transmitted directly to the control and the associated sealing elements.
Besonders vorteilhafter Weise ragt ein Ende eines ersten Hebels des Kniehebels über den Gelenkpunkt mit dem zweiten Hebel des Kniehebels hinaus und ist zur Verbindung mit dem Steuerelement ausgebildet. Hierdurch wird der Hubweg der Antriebseinheit bei gleichbleibendem Verfahrweg der Rücklaufmutter auf der Spindel in ergänzender Weise gesteigert. Zudem führt das Ende des ersten Hebels im wesentlichen eine reine Linearbewegung und keine Schwenkbewegung aus, so daß das Ende des ersten Hebels in besonders einfacher Weise mit dem Steuerelement gekoppelt werden kann. Das Ende des ersten Hebels ist hierzu entsprechend ausgebildet.Particularly advantageously, one end of a first lever of the toggle lever protrudes beyond the hinge point with the second lever of the toggle lever and is designed for connection to the control element. As a result, the stroke of the drive unit at a constant travel of the return nut on the spindle in a complementary manner increased. In addition, the end of the first lever performs essentially a pure linear movement and no pivoting movement, so that the end of the first lever can be coupled in a particularly simple manner with the control. The end of the first lever is designed accordingly.
Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist ein Federelement vorgesehen, das einenends an einem axial auf der Spindel verschiebbaren Drucklager und anderenends an einem Gewindelager anliegt, das durch Verdrehung der Spindel entlang der Spindelachse verfahrbar ist und wobei der Kniehebel mit seinem dem Spindellager gegegenüberliegenden Ende an dem Drucklager gelenkig gelagert ist, welches an der dem Federelement gegenüberliegenden Seite an der Rücklaufmutter anliegt.According to a particularly advantageous embodiment of the invention, a spring element is provided, which rests on one end on an axially displaceable on the spindle thrust bearing and the other end to a threaded bearing, which is movable by rotation of the spindle along the spindle axis and wherein the toggle lever with its end opposite to the spindle bearing the thrust bearing is articulated, which bears against the spring element on the opposite side of the return nut.
Gemäß dieser Ausgestaltung der Erfindung verschieben sich beim Verstellen der Antriebseinheit die Rücklaufmutter und das Gewindelager in gleichem Maße, wobei der Abstand zwischen diesen gleich bleibt. Die gelenkige Lagerung des Kniehebels an dem gegen die Federkraft verschiebbaren Drucklager ermöglicht es, die Dichtelemente mit einer konstanten Federkraft gegen den Fußboden oder die Decke zu drücken. Die Federkraft ist über die Festlegung des Abstands zwischen dem Drucklager und dem Gewindelager bei der Montage des Hubmoduls einstellbar. Die Antriebseinheit erzeugt selbst keine Anpreßkraft des Dichtprofils. Diese wird allein durch das Federelement erzielt. Die Position der Rücklaufmutter bestimmt die durch die Federkraft erzielte Auslenkung des Kniehebels.According to this embodiment of the invention, the return nut and the threaded bearing move to the same extent when adjusting the drive unit, the distance between them remains the same. The articulated mounting of the toggle lever on the displaceable against the spring force thrust bearing allows to press the sealing elements with a constant spring force against the floor or the ceiling. The spring force is adjustable on the determination of the distance between the thrust bearing and the threaded bearing during assembly of the lifting module. The drive unit itself does not generate a contact pressure of the sealing profile. This is achieved solely by the spring element. The position of the return nut determines the deflection of the toggle lever achieved by the spring force.
Als Federelement können grundsätzlich alle hierfür geeigneten Bauteile verwendet werden. Nach einer vorteilhaften Ausgestaltung wird diese jedoch durch eine koaxial auf der Spindel angeordnete Schraubendruckfeder gebildet. Gemäß dieser Weiterbildung der Erfindung kann die Baugröße des Hubmoduls besonders gering gehalten werden, was folglich zu einer nur sehr geringen Bauraumbeanspruchung in dein Wandkörper führt.As a spring element basically all suitable components can be used. According to an advantageous embodiment, however, this is formed by a coaxially arranged on the spindle helical compression spring. According to this embodiment of the invention, the size of the lifting module can be kept very low, which consequently leads to only a very small space requirement in your wall body.
Die Montage des Hubmoduls kann mit herkömmlichen Bauteilen in einfacher Weise realisiert werden. Eine besondere einfache Montage des Kniehebels wird gemäß einer Weiterbildung der Erfindung dadurch erreicht, daß die über einen Bolzen hergestellte Verbindung des ersten und zweiten Hebels in der Art eines Bajonett-Verschlusses ausgeführt ist, der derart ausgestaltet ist, daß ein Zusammenbau zum Kniehebel nur im Falle einer parallelen Ausrichtung der Hebel durchführbar ist. Diese Ausrichtung wird nur während der Montage erreicht. In der Einbaulage des Hubmoduls ist der Kniehebel aufgrund seiner Kopplung mit dem Steuerelement zumindest in einem gewissen Maße geknickt, so daß der erste und zweite Hebel nicht parallel zueinander ausgerichtet sind. Diese Ausgestaltung stellt eine besonders zuverlässige Art der Verbindung dar.The assembly of the lifting module can be realized with conventional components in a simple manner. A particular simple installation of the toggle lever is achieved according to a development of the invention in that the connection made via a bolt of the first and second lever is designed in the manner of a bayonet closure, which is designed such that an assembly to the toggle lever only in case a parallel orientation of the lever is feasible. This alignment is only achieved during assembly. In the installation position of the lifting module of the toggle lever is due to its coupling with the control at least to a certain extent kinked, so that the first and second lever are not aligned parallel to each other. This embodiment represents a particularly reliable type of connection.
Die manuelle Betätigung kann ebenfalls beliebig ausgeführt werden. Nach einer besonders vorteilhaften Weiterbildung der Erfindung wird diese jedoch durch eine Spindelverlängerung gebildet, die einerseits an einem Ende der Spindel verdrehfest und andererseits im Bereich der stirnseitigen Aufnahmeöffnungen angeordnet ist. Insofern kann in einfacher Weise mit geeignetem Werkzeug, bspw. mittels eines Innensechskantschlüssels oder dergleichen eine Verdrehung der Spindel bewirkt werden, so daß das Hubmodul trotz Ausfall der motorischen Einheit, bspw. eines Elektromotors, zwischen der Verfahrposition und der Funktionsposition verstellt werden kann. Das frei zugängliche Ende der Spindelverlängerung ist zur Aufnahme des Betätigungswerkzeugs ausgebildet.The manual operation can also be performed arbitrarily. According to a particularly advantageous embodiment of the invention, however, this is formed by a spindle extension which is arranged on the one hand rotationally fixed at one end of the spindle and on the other hand in the region of the end-side receiving openings. In this respect, a rotation of the spindle can be effected in a simple manner with a suitable tool, for example by means of a hexagon socket wrench or the like, so that the lifting module despite the failure of the motor unit, for example. An electric motor, can be adjusted between the travel position and the operating position. The freely accessible end of the spindle extension is designed to receive the operating tool.
