Description

Die Erfindung betrifft ein Schiebetürsystem für Kühlgeräte, mit wenigstens einem Türelement sowie mit einem Schließmechanismus umfassend wenigstens eine Antriebsvorrichtung, wenigstens eine Dämpfungsvorrichtung sowie wenigstens ein Aufnahmeelement.The invention relates to a sliding door system for refrigerators, with at least one door element and with a closing mechanism comprising at least one drive device, at least one damping device and at least one receiving element.

Derartige Schiebetürsysteme bzw. Schiebedeckelsysteme für Kühlgeräte sind im Stand der Technik bereits beschrieben.Such sliding door systems or sliding lid systems for refrigerators are already described in the prior art.

So offenbart zum Beispiel die DE 10 2009 016 208 A1 ein Schiebedeckelsystem für Kühlgeräte.
Dieses Schiebedeckelsystem weist einen ersten und einen zweiten Deckelteil auf, von denen wenigstens ein Deckelteil bewegbar ausgeführt ist und wobei die Deckelteile im geschlossenen Zustand in einer Ebene liegen. Bei diesem Schiebedeckelsystem ist die Führung des bewegbaren Deckelteils über Rollen realisiert, die in einer oder mehrerer Rollenbahnen laufen. Dadurch soll die Reibung beim Bewegen eines Deckelteils verringert werden und die Möglichkeit einer optimalen Abdichtung sowie eine präzise Deckelführung möglich sein. Dieses Schiebedeckelsystem ist so ausgelegt, dass es manuell durch den Benutzer zu bedienen ist, in dem der jeweils zu öffnende Deckelteil von Hand von einer Geschlossenstellung in eine Offenstellung bewegt wird.
Nachteilig bei diesem Schiebedeckelsystem für Kühlgeräte wird gesehen, dass durch die manuelle Bewegung der Deckelteile von einer Geschlossenstellung in eine Offenstellung die in dem Kühlgerät befindlichen Waren zwar entnommen werden können, dass es aber häufig passiert, dass danach das Deckelteil nicht wieder von der Offenstellung in die Geschlossenstellung überführt wird. Hierdurch erfolgt ein Luftaustausch, in dem die kühle Luft des Kühlgerätes in den Raum entweicht, was einerseits für die neben dem Kühlgerät sich bewegenden Benutzer unangenehm ist, was aber andererseits auch dazu führt, dass zur Kühlung der in dem Kühlgerät befindlichen Produkte ein höherer Energiebedarf erforderlich ist, da die im Kühlgerät sich erwärmende Luft wieder abgekühlt werden muss.For example, the DE 10 2009 016 208 A1 a sliding lid system for refrigerators.
This sliding cover system has a first and a second cover part, of which at least one cover part is designed to be movable and wherein the cover parts lie in the closed state in a plane. In this sliding lid system, the guide of the movable lid part is realized via rollers which run in one or more roller conveyors. This should reduce the friction when moving a cover part and the possibility of optimal sealing and a precise cover guide be possible. This sliding lid system is designed so that it can be operated manually by the user, in which the respectively openable lid part is moved by hand from a closed position to an open position.
A disadvantage of this sliding lid system for refrigerators is seen that the manual movement of the lid parts from a closed position to an open position, the goods located in the refrigerator can indeed be removed, but that it often happens that then the lid part not again from the open position in the Closed position is transferred. This results in an exchange of air, in which the cool air of the refrigerator escapes into the room, which on the one hand is uncomfortable for the user next to the refrigerator moving, but on the other hand also means that for cooling the products located in the refrigerator requires a higher energy demand is because the cooling air in the cooling unit must be cooled down again.

Weiterhin nachteilig wird gesehen, dass bei Entnahme von Produkten aus dem Kühlgerät der Benutzer möglicherweise eine oder keine Hand mehr frei hat, um dieses Deckelteil wieder zu verschließen.Another disadvantage is seen that when removing products from the refrigerator, the user may have one or no hand free to close this cover part again.

Ein weiteres Schiebedeckelsystem für Kühlgeräte ist in der DE 10118437 A1 offenbart. Dieses Kühlgerät, welches auch als Warenpräsentationsmöbel bezeichnet ist, weist eine Warenraumöffnung auf, die mittels eines oder mehrerer verfahrbarer Schiebedeckel zumindest teilweise verschließbar ist. Weiterhin weist dieses Kühlgerät Mittel zum automatischen Verfahren des oder der Schiebedeckel auf, die beispielsweise als Seil- und/oder Riemensystem ausgebildet sein können, bei dem der oder die Schiebedeckel mittels eines Antriebs über das Seil- und/oder Riemensystem verfahrbar sind. Es wird weiter offenbart, dass das Verfahren der Schiebedeckel von einer geschlossenen Stellung in eine Offenstellung durch Zahnräder und/oder Zahnstangendirektantriebe erfolgen kann oder auch über Reibradantriebe und/oder über Hydraulik- oder Pneumatikzylinder. Weiterhin soll dieses Kühlgerät Mittel zum Erfassen der Öffnungszeiten des Schiebedeckels aufweisen.
Diese Mittel können beispielsweise entsprechende Schalter sein, die den Schiebedeckel nach erfolgter Öffnung in einem bestimmten Zeitfenster automatisch wieder verschließen. Diese Mittel können beispielsweise auch Spracherkennungsvorrichtungen oder normale mechanische bzw. elektromechanische Schalter sein.
Nachteilig bei diesem Kühlgerät wird gesehen, dass trotz der die Öffnungszeit aufnehmenden Mittel das Kühlgerät trotzdem über eine längere Zeit geöffnet bleibt und somit die negativen Folgen des Luftaustausches auch bei diesem Kühlgerät auftreten. Dies führt wiederum dazu, dass das Kühlgerät einen erhöhten Bedarf an elektrischer Energie hat, um diese sich im Innenraum erwärmende Luft entsprechend wieder herunterzukühlen.Another sliding lid system for refrigerators is in the DE 10118437 A1 disclosed. This cooling device, which is also referred to as goods display furniture, has a goods space opening, which is at least partially closed by means of one or more movable sliding cover. Furthermore, this cooling device has means for automatically moving the sliding cover or covers, which may be formed, for example, as a cable and / or belt system, in which the sliding cover or covers are movable by means of a drive via the cable and / or belt system. It is further disclosed that the method of sliding cover from a closed position to an open position by gears and / or rack direct drives can be done or via Reibradantriebe and / or hydraulic or pneumatic cylinder. Furthermore, this cooling device should have means for detecting the opening times of the sliding cover.
By way of example, these means can be corresponding switches which automatically close the sliding cover again after opening in a specific time window. These means may also be, for example, speech recognition devices or normal mechanical or electromechanical switches.
A disadvantage of this cooling device is seen that despite the opening time receiving means the cooling device still remains open for a long time and thus the negative consequences of air exchange also occur in this cooling device. This in turn means that the cooling device has an increased demand for electrical energy in order to cool down this air warming in the interior again accordingly.

Ein weiterer Nachteil dieses Schiebetürsystems für Kühlgeräte wird darin gesehen, dass das Schließen des Kühlgerätes automatisch erfolgt und dass es hierbei durchaus passieren kann, dass ein Benutzer Gegenstände aus dem Kühlgerät entnehmen will und so eine Unfall- bzw. Verletzungsgefahr besteht, da der sich schließende Deckel bzw. die sich schließende Tür beispielsweise den Arm des Benutzers oder aber auch das Produkt, welches er herausnehmen will, einklemmt.
Die DE 29920016 U1 offenbart ein Schiebetürsystem gemäß dem Oberbegriff des Anspruchs 1. Dieses bekannte System weist eine Schiebetür und eine Schließvorrichtung auf, die die Schiebetür aus ihrer Offenstellung in eine Schließstellung bewegt, wobei die Schließvorrichtung ein Zuggewicht aufweist, das mit der Schiebetür verbunden ist und die Schiebetür in die Schließstellung zieht, wobei die Schließvorrichtung einen Dämpfungszylinder aufweist, in dem das Zuggewicht als in dem Dämpfungszylinder bewegbarer Kolben ausgebildet ist. Dieses Schiebetürsystem umfasst somit eine Antriebsvorrichtung in Form eines Seilzuges sowie des bewegbaren Kolbens und eine Dämpfungsvorrichtung in Form des Dämpfungszylinders mit wenigstens einem Dämpfungselement in Form eines Lüftungsmittels zur Belüftung des geschlossenen Zylinderendes.Another disadvantage of this sliding door system for refrigerators is seen in the fact that the closing of the refrigerator is automatic and that it may well happen that a user wants to remove items from the refrigerator and so there is an accident or injury, since the closing lid or the closing door, for example, the arm of the user or even the product he wants to take out, clamps.
The DE 29920016 U1 discloses a sliding door system according to the preamble of claim 1. This known system comprises a sliding door and a closing device, which moves the sliding door from its open position to a closed position, wherein the closing device has a draw weight, which is connected to the sliding door and the sliding door in the Closed position pulls, wherein the closing device comprises a damping cylinder, in which the draw weight is formed as in the damping cylinder movable piston. This sliding door system thus comprises a drive device in the form of a cable and the movable piston and a damping device in the form of the damping cylinder with at least one damping element in the form of a ventilation means for ventilating the closed cylinder end.

Die Führungsschienen im bekannten Stand der Technik, auf denen die Rollen der Türelemente gelagert sind bzw. auf denen sie verlaufen, sind nie exakt horizontal bzw. parallel zueinander angeordnet. Die für das Schließen der Türelemente erforderlichen Antriebsvorrichtungen wie Schraubenfedern, Schließgewichte, Seile usw. müssen dabei so dimensioniert werden, dass sich die Türelemente auch bei diesen ungünstigen Bedingungen immer noch sicher verschließen. Dies führt nachteiligerweise sehr oft dazu, dass die Antriebsvorrichtungen überdimensioniert sind, was zum einen die Kosten erhöht und zum anderen dazu führt, dass beim Verschließen der Türelemente diese heftig an der Seitenwand anschlagen. Die dabei derzeit verwendeten elastischen Dämpfungs- bzw. Dichtelemente können dies nur geringfügig reduzieren und stellen dabei aber teilweise eine optische Beeinträchtigung der Kühlgeräte dar.
Ein weiterer Nachteil des Standes der Technik besteht darin, dass bei der Verwendung von Schiebetürsystemen bzw. Schiebedeckelsystemen für Kühlgeräte mit zwei einander direkt gegenüberliegenden Tür- bzw. Deckelelementen diese beim Öffnen jeweils so bewegt werden müssen, dass ein Element über das andere Element hinweg bzw. hinter dem anderen Element verschiebbar ist. Durch diese mechanisch aufwendige Konstruktion ist es aber leider nicht möglich, bei geöffneter linker Tür die darunter bzw. dahinter befindliche rechte Tür ebenfalls zu öffnen.
Neben dem hohen Kraft- und Zeitaufwand dieser Schiebetürsysteme für Kühlgeräte ist somit auch die Zeitdauer des Öffnens bzw. Verschließens des Kühlgerätes relativ hoch, zumal von diesen Kühlgeräten gefordert ist, möglichst nebeneinander angeordnete Türen gleichzeitig zu öffnen, um die Waren zu entnehmen.The guide rails in the known state of the art, on which the rollers of the door elements are mounted or on which they run, are never exactly horizontal or parallel to each other. The required for closing the door elements drive devices such as coil springs, closing weights, ropes, etc., must be so dimensioned be that the door elements still close securely even in these unfavorable conditions. This leads disadvantageously very often to the fact that the drive devices are oversized, which on the one hand increases the cost and on the other results in that when closing the door elements strike them violently on the side wall. The currently used elastic damping or sealing elements can reduce this only slightly, but in some cases represent a visual impairment of the refrigerators.
Another disadvantage of the prior art is that when using sliding door systems or sliding lid systems for refrigerators with two directly opposite door or lid elements, these must each be moved when opening so that one element on the other element or is displaceable behind the other element. Due to this mechanically complex construction, however, it is unfortunately not possible to open the right-hand door underneath or behind it when the left-hand door is open.
In addition to the high expenditure of time and energy of these sliding door systems for refrigerators, the duration of opening or closing of the refrigerator is thus relatively high, especially since these refrigerators is required to open as possible adjacent doors simultaneously to remove the goods.

Hier setzt die Erfindung ein, die sich die Aufgabe gestellt hat, die Nachteile des Standes der Technik zu überwinden und ein Schiebetürsystem für Kühlgeräte aufzuzeigen, welches wirtschaftlich und kostengünstig herstellbar ist, das eine geräuscharme, schnelle und schonende Schließbewegung der Türelemente ermöglicht, das gleichzeitig den Energieverbrauch der Kühlgeräte senkt sowie die Lebensdauer des Schiebetürsystems verlängert.This is where the invention, which has set itself the task of overcoming the disadvantages of the prior art and to show a sliding door system for refrigerators, which is economical and inexpensive to produce, which allows a quiet, fast and gentle closing movement of the door elements, which simultaneously Energy consumption of refrigerators lowers and extends the life of the sliding door system.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.According to the invention, this object is solved by the features of claim 1. Further advantageous embodiments of the invention are described in the subclaims.

Das erfindungsgemäße Schiebetürsystem für Kühlgeräte mit wenigstens einem Türelement, sowie mit einem Schließmechanismus umfassend wenigstens eine Antriebsvorrichtung, wenigstens eine Dämpfungsvorrichtung sowie wenigstens ein Aufnahmeelement zeichnet sich dadurch aus, dass die Dämpfungsvorrichtung wenigstens ein Dämpfungselement und wenigstens ein Antriebselement, die parallel zueinander geschaltet und/oder angeordnet sind, aufweist, wobei das Aufnahmeelement beweglich an der Dämpfungsvorrichtung angeordnet ist, wobei die Antriebsvorrichtung so ausgebildet ist, dass das Türelement über einen Verfahrweg von einer Offenstellung in eine geschlossene Stellung bewegbar ist, dass am Türelement wenigstens ein Mitnahmeelement angeordnet ist, welches in der geschlossenen Stellung des Türelementes mit dem Aufnahmeelement in Wirkverbindung steht, dass nach einem definierten Verfahrweg des Türelementes von der geschlossenen Stellung in eine Offenstellung das Aufnahmeelement an der Dämpfungsvorrichtung arretiert und das Mitnahmeelement vom Aufnahmeelement beabstandet angeordnet ist. Hierdurch kann vorteilhafterweise erreicht werden, dass zum Verschließen des Kühlgerätes kurze Schließzeiten erreichbar sind und zusätzlich noch ein hartes Anschlagen der Türelemente an der Seitenwand wird. Weiterhin entstehen vorteilhafterweise keine Geräusche, wenn sich die Türelemente selbst schließen.The sliding door system according to the invention for refrigerators with at least one door element, and with a closing mechanism comprising at least one drive device, at least one damping device and at least one receiving element is characterized in that the damping device at least one damping element and at least one drive element connected in parallel and / or arranged are, wherein the receiving element is movably disposed on the damping device, wherein the drive device is formed so that the door element is movable over a path from an open position to a closed position that at least one driving element is arranged on the door element, which is in the closed position of the door element in operative connection with the receiving element that after a defined travel of the door element from the closed position to an open position the receiving element is locked to the damping device and the driving element is arranged spaced from the receiving element. As a result, it can be advantageously achieved that short closing times are achievable for closing the cooling device and, in addition, a hard striking of the door elements on the side wall is achieved. Furthermore, no noise is advantageously generated when the door elements close themselves.

Das erfindungsgemäße Schiebetürsystem für Kühlgeräte weist auch einen wesentlich reduzierteren Verschleiß der einzelnen Elemente auf.The sliding door system for refrigerators according to the invention also has a significantly reduced wear of the individual elements.

In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Schiebetürsystems für Kühlgeräte ist die Dämpfungsvorrichtung am Türelement selbst angeordnet. Dies hat den Vorteil, dass diese Türelemente die gewünschte Schließfunktion vollumfänglich realisieren können und gleichzeitig für bereits im Einsatz befindliche Kühlgeräte nachgerüstet werden könnenIn an advantageous embodiment of the sliding door system according to the invention for refrigerators, the damping device is arranged on the door element itself. This has the advantage that these door elements can fully realize the desired closing function and can be retrofitted at the same time for already in use refrigerators

Weiterhin vorteilhaft bei dem erfindungsgemäßen Schiebetürsystem für Kühlgeräte wird gesehen, dass die Dämpfungsvorrichtung am Korpus des Kühlgerätes angeordnet ist. Dies lässt sich insbesondere bei der Herstellung der Kühlgeräte kostengünstig, aber auch optisch ansprechend realisieren.Furthermore advantageous in the sliding door system for refrigerators according to the invention is seen that the damping device is arranged on the body of the refrigerator. This can be implemented inexpensively, but also visually appealing, particularly in the production of refrigerators.

Das erfindungsgemäße Schiebetürsystem zeichnet sich weiterhin dadurch aus, dass die Antriebsvorrichtung, welche den Türelementen eine selbstständige Bewegung von der Offenstellung in die geschlossene Stellung ermöglicht, dabei als Federelement ausgebildet ist. Dabei kommen an sich bekannte Schraubenfedern, Torsionsfedern und dergleichen zur Anwendung, welche eine genau dimensionierbare und dosierbare Schließbewegung der Türelemente über den Verfahrweg ermöglichen.The sliding door system according to the invention is further distinguished by the fact that the drive device, which allows the door elements to move independently from the open position into the closed position, is designed as a spring element. In this case, known coil springs, torsion springs and the like are used, which allow a precisely dimensioned and metered closing movement of the door elements via the travel path.

Dabei kann es ebenfalls von Vorteil sein, wenn das erfindungsgemäße Schiebetürsystem eine Antriebsvorrichtung aufweist, die als ein ein Gewichtselement aufweisendes Seil ausgebildet ist. Durch diese vorteilhafte Gestaltung ist es möglich, alle Größen bzw. Gewichte von Türelementen bei derartigen Kühlgeräten optimal zu bewegen.It may also be advantageous if the sliding door system according to the invention comprises a drive device which is designed as a rope having a weight element. This advantageous design makes it possible to optimally move all sizes or weights of door elements in such refrigerators.

Es hat sich weiterhin vorteilhaft herausgestellt, dass bei dem erfindungsgemäßen Schiebetürsystem das Aufnahmeelement gegenüber dem Mitnahmeelement verschwenkbar angeordnet ist. Dadurch kann erfindungsgemäß erreicht werden, dass beim Bewegen der Türelemente von der geschlossenen Stellung in die Offenstellung über das Mitnahmeelement das Aufnahmeelement über den definierten Verfahrweg mitgeführt wird und an der definierten Position durch die Verschwenkbewegung das Mitnahmeelement freigibt, sodass das Türelement bis zur maximalen Offenstellung bewegbar ist.It has also been found to be advantageous that in the sliding door system according to the invention, the receiving element is arranged pivotably relative to the driving element. As a result, it can be achieved according to the invention that when the door elements are moved from the closed position into the open position via the entrainment element, the receiving element is guided over the defined travel path and releases the entrainment element at the defined position by the pivoting movement, so that the door element can be moved to the maximum open position ,

Es hat sich weiterhin als vorteilhaft herausgestellt, dass das Dämpfungselement der Dämpfungsvorrichtung als Rotationsdämpfer ausgebildet ist. Hierdurch ist es vorteilhafterweise möglich, Türelemente in verschiedenen Größen und Gewichten mit einer einzigen Dämpfungsvorrichtung auszustatten, sodass das erfindungsgemäße Schiebetürsystem für Kühlgeräte kostengünstig und optimal einsetzbar ist.It has also proven to be advantageous that the damping element of the damping device is designed as a rotary damper. As a result, it is advantageously possible to equip door elements of different sizes and weights with a single damping device, so that the sliding door system according to the invention for refrigerators is inexpensive and optimally applicable.

Es hat sich weiterhin als vorteilhaft herausgestellt, wenn das als Rotationsdämpfer ausgebildete Dämpfungselement mit einer Zahnstange in Wirkverbindung steht.It has also proven to be advantageous if the damping element designed as a rotary damper is in operative connection with a toothed rack.

Durch diese vorteilhafte Ausgestaltung ist es möglich, den definierten Verfahrweg von einer Offenstellung in die Geschlossenstellung der Türelemente so abzubremsen, dass die letzten beispielsweise 3 bis 15 cm, die das Türelement bis zur geschlossenen Stellung noch bewegt werden muss, mit einer gleichförmigen und geringen Geschwindigkeit realisierbar sind. Hierdurch wird erreicht, dass ein Nutzer, der in das Innere des Kühlgerätes noch hineingreifen will, durch die sich sonst schnell und hart schließenden Türelemente nicht eingeklemmt bzw. beeinträchtigt ist. Somit kann bei dem erfindungsgemäßen Schiebetürsystem für Kühlgeräte auf separate Vorrichtungen zur Verhinderung von Quetschungen oder anderen Beeinträchtigungen der Benutzer verzichtet werden.This advantageous embodiment, it is possible to decelerate the defined travel from an open position to the closed position of the door elements so that the last example, 3 to 15 cm, the door element has yet to be moved to the closed position, with a uniform and low speed feasible are. This ensures that a user who still wants to reach into the interior of the refrigerator, is not trapped or impaired by the otherwise fast and hard-closing door elements. Thus, in the sliding door system for refrigerators according to the invention, separate devices for preventing bruising or other impairments of the user can be dispensed with.

In einer weiteren vorteilhaften Ausgestaltung ist das Dämpfungselement der Dämpfungsvorrichtung als Lineardämpfer ausgebildet. Insbesondere durch die Kombination von Rotations- bzw. Lineardämpfern kann die Lebensdauer der Dämpfungsvorrichtung und damit des erfindungsgemäßen Schiebetürsystems für Kühlgeräte erheblich verlängert werden, da das erfindungsgemäße Schiebetürsystem nur einen definierten Verfahrweg von etwa 3 bis 15 cm bis zur geschlossenen Stellung des Türelementes mit diesem in Wirkverbindung steht.In a further advantageous embodiment, the damping element of the damping device is designed as a linear damper. In particular, by the combination of rotary and linear dampers, the life of the damping device and thus the sliding door system for refrigerators according to the invention can be considerably extended because the sliding door system according to the invention only a defined travel of about 3 to 15 cm to the closed position of the door element with this in operative connection stands.

In einer weiteren ebenfalls vorteilhaften Ausgestaltung des erfindungsgemäßen Schiebetürsystems für Kühlgeräte sind die Dämpfungsvorrichtung und die Antriebsvorrichtung wenigstens teilweise parallel zueinander angeordnet und/oder geschalten. Durch diese Anordnung ist es möglich, dass das erfindungsgemäße Schiebetürsystem für Kühlgeräte sehr kompakt und platzsparend herstellbar und im Kühlgerät anordenbar ist. Es wird weiterhin vorteilhafterweise erreicht, dass bei einer Anordnung des erfindungsgemäßen Schiebetürsystems für Kühlgeräte oberhalb von Führungsschienen die Dämpfungsvorrichtung nicht mit der gekühlten Luft des Innenraums der Kühlgeräte in Kontakt kommt und somit unabhängig von der Raumtemperatur sowie von der Temperatur im Inneren des Kühlgerätes konstant funktioniert. Die Dämpfungsvorrichtung ist somit nicht unterschiedlichen Temperaturen ausgesetzt, die beispielsweise beim Öffnen der Türelemente des Schiebetürsystems entstehen und die das Dämpfungsverhalten beeinflussen sowie die gedämpfte Schließbewegung des Türelementes temperaturabhängig verändern.In a further likewise advantageous embodiment of the sliding door system according to the invention for refrigerators, the damping device and the drive device are at least partially arranged parallel to each other and / or switched. With this arrangement, it is possible that the sliding door system according to the invention for refrigerators is very compact and space-saving to produce and can be arranged in the refrigerator. It is further advantageously achieved that in an arrangement of the sliding door system according to the invention for cooling devices above guide rails, the damping device does not come into contact with the cooled air of the interior of the cooling units and thus operates independently of the room temperature and the temperature inside the refrigerator constant. The damping device is thus not exposed to different temperatures, which arise for example when opening the door elements of the sliding door system and which influence the damping behavior and change the damped closing movement of the door element temperature-dependent.

Das erfindungsgemäße Schiebetürsystem für Kühlgeräte soll nun an Ausführungsbeispielen, die die Erfindung aber nicht einschränken, näher beschrieben werden.The sliding door system for refrigerators according to the invention will now be described in more detail on embodiments, which do not limit the invention.

In der Figur 1 ist eine perspektivische Darstellung eines Kühlgerätes 1 dargestellt. Das Kühlgerät 1 weist einen Korpus auf, der gebildet ist von den Seitenwänden 4, 5, dem Boden 6, dem Oberboden 7 und der Rückwand 8.
Die Öffnung des Korpus ist durch die Türelemente 2, 3 verschließbar. Dabei ist das Türelement 3 des Kühlgerätes 1 in der geschlossenen Stellung GS dargestellt, während das Türelement 2 des Kühlgerätes 1 in einer Offenstellung OS dargestellt ist, wobei zwischen der Lähgsseite des Türelements 2 und der Seitenwand 4 des Kühlgerätes 1 eine Öffnung entsteht und der Abstand zwischen der Seitenwand 4 und der Längsseite des Türelementes 2 des Kühlgerätes 1 den Verfahrweg V definiert.
Bei dem Kühlgerät 1 sind die Türelemente 2, 3 so angeordnet, dass diese parallel zueinander gegeneinander bewegbar sind und jeweils von der geschlossenen Stellung GS in eine offene Stellung OS über den Verfahrweg V bewegbar sind und der hier nicht dargestellte Schließmechanismus dafür sorgt, dass die Türelemente 2, 3 von der Offenstellung OS über den Verfahrweg V in eine geschlossene Stellung GS selbstständig bewegbar sind.In the FIG. 1 is a perspective view of a refrigerator 1 is shown. The cooling device 1 has a body which is formed by the side walls 4, 5, the bottom 6, the top floor 7 and the rear wall 8.
The opening of the body can be closed by the door elements 2, 3. In this case, the door element 3 of the refrigerator 1 is shown in the closed position GS, while the door element 2 of the refrigerator 1 is shown in an open position OS, wherein between the Lähgsseite of the door element 2 and the side wall 4 of the refrigerator 1, an opening is formed and the distance between the side wall 4 and the longitudinal side of the door element 2 of the cooling device 1 defines the travel path V.
In the cooling device 1, the door elements 2, 3 are arranged so that they are mutually movable parallel to each other and are each movable from the closed position GS in an open position OS on the travel path V and not shown here Closing mechanism ensures that the door elements 2, 3 are independently movable from the open position OS via the travel path V in a closed position GS.

In der Figur 2 ist eine teilweise geschnittene Vorderansicht eines erfindungsgemäßen Schiebetürsystems für Kühlgeräte 1 dargestellt. Das Kühlgerät 1 weist dabei die Seitenwände 4, 5, den Boden 6, den Oberboden 7 und eine Rückwand 8 auf.
Der besseren Übersichtlichkeit halber ist nur das Türelement 2 dargestellt. Das Türelement 2 ist in einer Offenstellung OS dargestellt und über einen Verfahrweg V von der Seitenwand 4 entfernt. Das Türelement 2 des Kühlgerätes 1 weist an seinem oberen freien Ende in diesem Ausführungsbeispiel zwei Rollen 9, 91 auf, die in einem unterhalb des Oberbodens 7 angeordneten Führungsschienensystem 10 drehbeweglich geführt sind.
In diesem Ausführungsbeispiel ist an der linken Längsseite des Türelementes 2 oberhalb der Rolle 9 das Mitnahmeelement 50 angeordnet, welches im Querschnitt eine etwa U-förmige Geometrie aufweist.
An der rechten Längsseite des Türelementes 2 ist oberhalb der Rolle 91 ein Halteelement 24 angeordnet. Am Halteelement 24 des Türelementes 2 ist die Antriebsvorrichtung 20 angeordnet, die als ein ein Gewichtselement 22 aufweisendes Seil 21 ausgebildet ist.
Das Seil 21 ist dabei bei dem erfindungsgemäßen Schiebetürsystem für Kühlgeräte 1 so angeordnet, dass es oberhalb des Führungsschienensystems 10 sowie unterhalb des Oberbodens 7 parallel zur Dämpfungsvorrichtung 30 verläuft und über das Umlenkelement 23 zwischen der Seitenwand 4 und der Seitenwand 4' am Gewichtselement 22 endet. Durch das Bewegen des Türelementes 2 von der geschlossenen Stellung GS in die Offenstellung OS wird über das Haltelement 24 das Gewichtselement 22 in seiner vertikalen Position verändert und sobald das Türelement 2 durch den Benutzer nicht mehr gehalten wird, wird dieses durch das Gewichtselement 22 und das Seil 21 von der Offenstellung OS selbstständig in die Geschlossenstellung GS über den Verfahrweg V bewegt.
In der dargestellten Offenstellung OS ist das Mitnahmeelement 50 beabstandet vom Aufnahmeelement 40 der Dämpfungsvorrichtung 30 angeordnet, wobei gleichzeitig das Aufnahmeelement 40 an der Dämpfungsvorrichtung 30 arretiert ist. Die Dämpfungsvorrichtung 30 weist ein Gehäuse mit einem Dämpfungselement 31 und einem Antriebselement 32 auf. In diesem Ausführungsbeispiel ist das Antriebselement 32 als Schraubenfeder ausgebildet und mit dem Dämpfungselement 31, welches ein Lineardämpfer ist, parallel zueinander geschaltet und/oder angeordnet. Das Aufnahmeelement 40 ist dabei aber beweglich an dem Gehäuse der Dämpfungsvorrichtung 30 angeordnet. Beim Verschließen des Türelementes 2 wird nach einem definierten Verfahrweg VD das Mitnahmeelement 50 mit dem Aufnahmeelement 40 in Wirkverbindung treten, wobei hierdurch die Schließbewegung des Türelementes 2 des Kühlgerätes 1 reduziert bzw. gedämpft wird. Die Schließgeschwindigkeit des Türelementes 2 wird so stark reduziert, dass dieses über den definierten Verfahrweg VD erheblich langsamer zur Seitenwand 4' bewegt ist.In the FIG. 2 is a partially sectioned front view of a sliding door system according to the invention for refrigerators 1 shown. The cooling unit 1 has the side walls 4, 5, the bottom 6, the top bottom 7 and a rear wall 8.
For better clarity, only the door element 2 is shown. The door element 2 is shown in an open position OS and removed from the side wall 4 via a travel path V. The door element 2 of the cooling device 1 has at its upper free end in this embodiment, two rollers 9, 91, which are rotatably guided in a arranged below the top 7 guide rail system 10.
In this embodiment, the driving element 50 is arranged on the left longitudinal side of the door element 2 above the roller 9, which has an approximately U-shaped geometry in cross section.
On the right longitudinal side of the door element 2, a holding element 24 is disposed above the roller 91. On the holding element 24 of the door element 2, the drive device 20 is arranged, which is designed as a weight element 22 having a cable 21.
The cable 21 is in the sliding door system for refrigerators 1 according to the invention arranged so that it is above the guide rail system 10 and below the top 7 parallel to the damping device 30 and ends on the deflection element 23 between the side wall 4 and the side wall 4 'on the weight member 22. By moving the door element 2 from the closed position GS to the open position OS, the weight element 22 is changed in its vertical position via the holding element 24 and as soon as the door element 2 is no longer held by the user, it is replaced by the weight element 22 and the rope 21 moves automatically from the open position OS to the closed position GS via the travel path V.
In the illustrated open position OS, the driving element 50 is spaced from the receiving element 40 of the damping device 30, wherein at the same time the receiving element 40 is locked to the damping device 30. The damping device 30 has a housing with a damping element 31 and a drive element 32. In this embodiment, the drive element 32 is designed as a helical spring and with the damping element 31, which is a linear damper, connected in parallel and / or arranged. The receiving element 40 is, however, movably arranged on the housing of the damping device 30. When closing the door element 2, the carrier element 50 is in operative connection with the receiving element 40 after a defined travel path VD, whereby thereby the closing movement of Door element 2 of the cooling unit 1 is reduced or damped. The closing speed of the door element 2 is reduced so much that it is moved much slower to the side wall 4 'on the defined travel VD.

In der Figur 3 ist eine teilweise geschnittene Draufsicht des Kühlgerätes 1 dargestellt. In dieser Draufsicht weist das Kühlgerät 1 die Seitenwände 4, 5, eine Rückwand 8 sowie einen Boden 6 auf. An dem nicht dargestellten Oberboden 7 sind die Dämpfungsvorrichtungen 30 jeweils einander gegenüberliegend angeordnet. Es liegt jedoch auch im Rahmen der Erfindung, dass die Dämpfungsvorrichtungen 30 an den Seitenwänden 4, 5 angeordnet sind.
In diesem Ausführungsbeispiel ist das Türelement 2 von der geschlossenen Stellung GS in die Offenstellung OS über den Verfahrweg V bewegt dargestellt. Das Türelement 2 weist eine Antriebsvorrichtung 20 auf, die in diesem Ausführungsbeispiel als Federelement ausgebildet ist. An der in diesem Ausführungsbeispiel linken Seite des Türelementes 2 ist das Mitnahmeelement 50 angeordnet, welches in der Offenstellung beabstandet vom Aufnahmeelement 40 positioniert ist.
Die Dämpfungsvorrichtung 30 weist ein Aufnahmeelement 40 auf, welches beweglich an der Dämpfungsvorrichtung 30 angeordnet und über den definierten Verfahrweg VD beabstandet von der Seitenwand 4 positioniert ist.
Durch die als Federelement ausgebildete Antriebsvorrichtung 20 ist das Türelement 2 von der Offenstellung OS über den Verfahrweg V in die geschlossene Stellung GS bewegbar. Diese Situation ist in diesem Ausführungsbeispiel durch das Türelement 3 dargestellt. Das Türelement 3 wurde von einer hier nicht dargestellten Offenstellung OS durch die als Federelement ausgebildete Antriebsvorrichtung 20 in die geschlossene Stellung GS über die Rollen 9, 91 in dem nicht dargestellten Führungsschienensystem 10 bewegt und liegt mit seiner rechten Seite an der Innenseite der Seitenwand 5 an.
Am Türelement 3 ist das Mitnahmeelement 50 angeordnet. Bei der Bewegung des Türelementes 3 von der Offenstellung OS in die geschlossene Stellung GS tritt das Mitnahmeelement 50 nach einem definierten Verfahrweg VD mit dem Aufnahmeelement 40 in Wirkverbindung. Durch das in der Dämpfungsvorrichtung 30 angeordnete und hier nicht sichtbare Dämpfungselement 31 sowie das Antriebselement 32 wird die Schließgeschwindigkeit des Türelementes 3 reduziert und durch das in Richtung der Seitenwand 4, 5 beweglich an der Dämpfungsvorrichtung 30 angeordnete Aufnahmeelement 40 wird das Türelement 3 abgebremst und mit reduzierte Geschwindigkeit in die geschlossene Stellung GS überführt. In der geschlossenen Stellung GS des Türelementes 3 steht das Aufnahmeelement 40 mit dem Mitnahmeelement 50 in Wirkverbindung.In the FIG. 3 is a partially sectioned plan view of the refrigerator 1 is shown. In this plan view, the cooling device 1, the side walls 4, 5, a rear wall 8 and a bottom 6. At the upper floor 7, not shown, the damping devices 30 are each arranged opposite one another. However, it is also within the scope of the invention that the damping devices 30 are arranged on the side walls 4, 5.
In this exemplary embodiment, the door element 2 is shown moved from the closed position GS to the open position OS via the travel path V. The door element 2 has a drive device 20, which is formed in this embodiment as a spring element. At the left in this embodiment, the door element 2, the driving element 50 is arranged, which is positioned in the open position spaced from the receiving element 40.
The damping device 30 has a receiving element 40, which is movably arranged on the damping device 30 and positioned over the defined travel path VD spaced from the side wall 4.
By trained as a spring element drive device 20, the door element 2 from the open position OS on the travel V in the closed position GS is movable. This situation is represented by the door element 3 in this embodiment. The door element 3 was moved from an open position OS (not shown here) by the drive device 20 designed as a spring element into the closed position GS via the rollers 9, 91 in the guide rail system 10, not shown, and lies with its right side against the inside of the side wall 5.
On the door element 3, the driving element 50 is arranged. During the movement of the door element 3 from the open position OS to the closed position GS, the carrier element 50 comes into operative connection with the receiving element 40 in accordance with a defined travel path VD. By arranged in the damping device 30 and not visible here damping element 31 and the drive element 32, the closing speed of the door element 3 is reduced and arranged in the direction of the side wall 4, 5 movably arranged on the damping device 30 receiving element 40, the door element 3 is braked and reduced Speed in the closed position GS transferred. In the closed position GS of the door element 3, the receiving element 40 is in operative connection with the driving element 50.

Bei der Schließbewegung des Türelementes 2, 3 kommt es beim Erreichen des definierten Verfahrweges VD weiterhin vorteilhafterweise dazu, dass das Mitnahmeelement 50 das Aufnahmeelement 40 aus seiner arretierten Position heraus verschwenkt und mit diesem so lange in Wirkverbindung steht, bis das Türelement 2, 3 die geschlossene Stellung GS erreicht hat. Bei einem Bewegen des Türelementes 2, 3 von der geschlossenen Stellung GS in die Offenstellung OS wird das Mitnahmeelement 50 das Aufnahmeelement 40, welches beweglich an der Dämpfungsvorrichtung 30 angeordnet ist, über einen definierten Verfahrweg VD bewegen, das Aufnahmeelement 40 wird in der Position des definierten Verfahrweges VD an der Dämpfungsvorrichtung 30 arretiert und das Türelement 2, 3 wird weiter in die offene Stellung OS bewegt. Dabei liegt es aber auch im Rahmen der Erfindung, dass die Dämpfungsvorrichtung 30 direkt am Türelement 2, 3 angeordnet ist.During the closing movement of the door element 2, 3, when the defined travel path VD is reached, advantageously, the entrainment element 50 pivots the receiving element 40 out of its locked position and remains in operative connection therewith until the door element 2, 3 closes Position GS has reached. When moving the door element 2, 3 from the closed position GS in the open position OS, the driving element 50, the receiving element 40, which is movably disposed on the damping device 30, move over a defined travel VD, the receiving element 40 is defined in the position of Traversing VD locked to the damping device 30 and the door element 2, 3 is moved further in the open position OS. It is also within the scope of the invention that the damping device 30 is arranged directly on the door element 2, 3.
