- This upward movement allows the safety slide 60 to move in accordance with FIG FIG. 13 is pushed to the right, due to the force of the compression spring 90 and thereby with its legs 62, the pins 74 of the locking element 70 engages under, so that the locking member 70 is not unintentionally back to the position according to FIG. 12 , that is moved to the locking position.
- FIG. 13 In the FIG. 13 is shown a position in which now due to the upwardly pivoted locking element 70, the pin 22 can be removed from the locking position, so that a further door opening causes a separation between the lever and the locking element or slide.
- FIG. 14 shows the arrangement according to FIG. 12 without safety slide and illustrates that the locking element 70 is designed as a one-piece component which is arranged pivotably about an axis 74 on the slide carrier 50.
- a multi-part embodiment of the locking element 70 is conceivable and of the Invention comprises.
- the pin 22 of the lever 20 is held by positive engagement in the groove-shaped receptacle 73 of the locking element 70. If this is pivoted upward, as in FIG. 15 is shown, the pin 22 and thus the lever 20 relative to the locking member 70 and thus also relative to the slide and the damper 40 are moved.
- a helical spring which can be designed as tension or compression spring and can be arranged in or on the damper 40, a tensile force (according to the figures to the left) on the slide 50 and on the Locking element ("control claw"), which serves as a connecting element between the lever 20 and the slide carrier 50 and the damper 40, applied.
- the connecting element 70 is by positive engagement with the lever 20 in engagement.
- the force exerted by said spring or other pulling or pushing element force is transmitted to the lever 20 via the locking element 70.
- the lever 20 is moved. This exerts on the linkage in the gate bearing block 30 a closing moment on the door, not shown.
- the lever 20 is then out of engagement and is powerless, which means in other words that the door is not moved from this opening angle (for example, 35 °), as this acts neither a closing nor an opening moment.
- the spring-loaded safety slide 60 is brought via a second control cam in the module housing into a position via a further compression spring 90, in which the control claw or the locking element 70 is locked in the release position or in the prestressed position. This prevents inadvertent recovery of the under-standing sliding support locking element unit.
- the damper may be an oil-air damper or even pure air damper, for example, for applications on equipment with less damping power requirement. Conceivable this would be a freezer with less door mass. Other cost-effective damper solutions that meet the corresponding requirements are also possible.
- the lever 20 is forcibly guided by its module housing side backdrop via a brake area 80, ie the lever 20 is thus braked.
- the hitherto still powerless lever is first moved in the gate 34 of the sliding block 30 in the remote from the door pivot point 32 end portion A of the link 34.
- a movement of area B in area A takes place.
- the pin 24 of the lever 20 is in the region A, ie in the region of the link 34 spaced from the door pivot point 22. In this position, the lever or the link 34 serves as a load-receiving position of the damping forces.
- the brake area 80 can be designed via at least one additional component with different braking effect (eg for different door masses).
- this braking area designed via the additional component can be designed along its length (braking distance) with different stiffnesses (via geometric variations or via the use of different material sections) in different braking positions corresponding to brake action-dependent adapted braking action.
- the safety slide 60 is first moved in the further movement of the lever 20 so that the control claw or the locking element 70 is unlocked, d. H. the pin 22 engages behind a positive fit. In this way, the safety slide 60 is given the opportunity to move out of the secured biased position.
- the locking element 70 is moved due to the further movement of the lever by the link track 14, 14 'from the secured biased position. In this way, the system of lever 20 with sliding carrier 50, locking member 70 and damper 40 comes back into engagement.
- the damper 40 can thus counter its damping force to the lever 20 so that the kinetic energy of the door closing movement is damped, d. H. is reduced or destroyed. As stated above, this damping takes place, for example, via the use of an oil-air damper speed-dependent.
- the applied damping energy depends on the door closing speed, the door opening position from which the door closing movement is started, and also from the door mass.
- the system has in the range ⁇ 35 °, ie the system is in engagement, both functional states (damping and self-closing) interacting. This means that when the kinetic energy of the door is destroyed, the self-closing automatically takes effect and closes the door, ie the system exerts a closing moment on the door.
- angles of e.g. 35 ° or 115 ° are exemplary and not limit the invention.
- the lever 20 In this position, the lever 20 is located with its pin 22 in the bearing block end of the gate 80 and bearing block side in the door pivot point 22 near end portion of the link 34, d. H. in area B. In this position, the system module lever-bearing block is in an extended position and is loaded on train. In order to form the sliding end positions still damping effect, it may be useful and is included by the invention to provide one or more elastic elements, so that the attack situation is also damped.

Aus dem Stand der Technik ist es bekannt, bei Kühl- und/oder Gefriergeräten Schließdämpfer vorzusehen, die die Tür gedämpft in eine Schließstellung bewegen. Auf diese Weise kann zum einen verhindert werden, dass die Tür offen stehen bleibt. Zum anderen wird erreicht, dass die Tür nicht zuschlägt, sondern gedämpft in die Schließstellung überführt wird.From the prior art it is known to provide in refrigerators and / or freezers closing damper, which move the door damped in a closed position. In this way, on the one hand, it can be prevented that the door remains open. On the other hand it is achieved that the door does not strike, but is transferred damped into the closed position.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend weiterzubilden, dass ein hoher Bedienungscomfort für den Nutzer erreicht wird.The present invention has the object of developing a refrigerator and / or freezer of the type mentioned in that a high ease of operation for the user is achieved.
Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst. Danach ist vorgesehen, dass die die Schließeinheit derart ausgebildet ist, dass diese das genannte Schließmoment auf die Tür bei Erreichen oder Unterschreiten eines bestimmten Türöffnungswinkels ausübt und auf die Tür bei Überschreiten des bestimmten Türöffnungswinkels weder Schließ- noch Öffnungsmomente einwirken. Erfindungsgemäß ist somit vorgesehen, dass die Tür in einem bestimmten Winkelbereich dort stehen bleibt, wo der Nutzer dies wünscht, da in diesem Bereich weder ein Öffnungs- noch ein Schließmoment auf die Tür einwirkt.This object is achieved by a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that the closing unit is designed such that it exerts said closing moment on the door when reaching or falling below a certain door opening angle and act on the door when closing the specific door opening angle neither closing nor opening moments. According to the invention it is thus provided that the door remains in a certain angular range where the user desires, since in this area neither an opening nor a closing moment acts on the door.
Bei Erreichen oder Unterschreiten eines bestimmten Winkels greift die Schließeinheit ein und zieht die Tür in ihre Schließstellung. Ein versehentliches Offenstehen der Tür wird somit verhindert.When reaching or falling below a certain angle, the closing unit engages and pulls the door in its closed position. An accidental open the door is thus prevented.
Vorzugsweise ist vorgesehen, dass an dem Korpus wenigstens eine Halterung angeordnet ist und dass sich wenigstens ein Hebel von der Halterung zu der Schließeinheit oder zu einem Modul erstreckt, in dem sich die Schließeinheit befindet.It is preferably provided that at least one holder is arranged on the body and that at least one lever extends from the holder to the closing unit or to a module in which the closing unit is located.
In bevorzugter Ausgestaltung der Erfindung ist die Halterung als Lagerbock ausgebildet , an dem die Tür schwenkbar gelagert ist. Die Halterung erfüllt in diesem Fall somit sowohl die Funktion der Kulisse für den Hebel als auch die Funktion der Türlagerung.In a preferred embodiment of the invention, the holder is designed as a bearing block, on which the door is pivotally mounted. The holder thus fulfills both the function of the gate for the lever and the function of the door storage in this case.
Vorzugsweise ist vorgesehen, dass sich sowohl in der Halterung als auch in dem genannten Modul oder an sonstiger Position der Tür wenigstens eine Kulisse befindet, in der der Hebel geführt ist. Der Hebel ist vorzugsweise in einem Ende in der Kulisse des Lagerbocks und in seinem anderen Ende in einer türseitigen Kulisse geführt. Beim Öffnen und beim Schließen der Tür durchläuft der Hebel unterschiedliche Positionen der Kulissen. Eine Endposition der Türöffnung wird somit durch die Anordnung und die Länge der Kulissen definiert.It is preferably provided that there is at least one link in which the lever is guided, both in the holder and in said module or at another position of the door. The lever is preferably guided in one end in the backdrop of the bearing block and in its other end in a door-side scenery. When opening and closing the door, the lever passes through different positions of the scenes. An end position of the door opening is thus defined by the arrangement and the length of the scenes.
Die Schließeinheit kann mit wenigstens einem Gleitträger in Verbindung stehen, der in einer ersten Position mit dem Hebel derart in Verbindung steht, dass der Hebel an dem Gleitträger fixiert ist und der in einer zweiten Position unabhängig von dem Hebel bewegbar ist. Der Gleitträger ist entlang einer vorzugsweise geraden Bahn verschiebbar, die Bestandteil des Moduls ist. Er kann ebenfalls in einer Kulisse des Modulgehäuses geführt sein.The closing unit may be in communication with at least one slide carrier which is in a first position in communication with the lever such that the lever is fixed to the slide carrier and which is movable in a second position independent of the lever. The slide carrier is displaceable along a preferably straight path, which is part of the module. It can also be performed in a backdrop of the module housing.
Der Gleitträger wird beim Öffnen und Schließen der Tür hin und herbewegt, solange der Hebel mit dem Gleitträger in Verbindung steht.The slide is moved back and forth as the door is opened and closed as long as the lever is in contact with the slide.
Der Gleitträger kann wenigstens ein Verriegelungselement aufweisen, das in der ersten Position den Hebel an dem Gleitträger durch Formschluss fixiert und in der zweiten Position den Hebel freigibt, so dass der Hebel nicht an dem Gleitträger fixiert ist. Das Verriegelungselement kann schwenkbar an dem Gleitträger befestigt sein.The sliding support may have at least one locking element, which fixes the lever on the sliding support in the first position by positive locking and releases the lever in the second position, so that the lever is not fixed to the sliding support. The locking element may be pivotally attached to the slide carrier.
Das Verrieglungselement kann in wenigstens einer Kulisse geführt sein und in seiner zweiten Position, in der der Hebel freigegeben ist, in Richtung auf die erste Position hin vorgespannt sein. Das Verriegelungselement kann durch einen Sicherungsschieber in seiner zweiten Position gehalten werden.The locking element may be guided in at least one slot and in its second position, in which the lever is released, be biased in the direction of the first position. The locking element can be held in its second position by a safety slide.
Der Sicherungsschieber kann in gleicher Richtung wie der Gleitträger bewegbar angeordnet sein und relativ zu diesem federbelastet sein. Der Abstand zwischen Gleitträger und Sicherungsschieber kann veränderlich sein.The safety slide can be movably arranged in the same direction as the slide carrier and be spring-loaded relative to this. The distance between the slide and the safety slide can be variable.
Es kann wenigstens ein Dämpfer vorgesehen sein, der mit der mit dem Gleitträger derart in Verbindung steht, dass der Bewegung des Gleitträgers in wenigstens einer Bewegungsrichtung durch den Dämpfer eine Gegenkraft entgegengesetzt wird.At least one damper can be provided, which is connected to the sliding carrier in such a way that the movement of the slide carrier in at least one direction of movement through the damper is counteracted by a counterforce.
Die Schließeinheit kann wenigstens eine das Schließmoment aufbringende Zug- oder Druckfeder aufweisen. Sie kann einen Bestandteil des Dämpfers bilden oder an dem Dämpfer angeordnet sein.The closing unit may have at least one tension or compression spring applying the closing moment. It may form part of the damper or be arranged on the damper.
Die Kulisse der Halterung bzw. des Lagerbocks kann derart ausgebildet sein, dass sich der Hebel bei vollständig geöffneter Tür in einem Bereich der Kulisse und bei der Tür in Schließstellung in einem anderen Bereich der Kulisse befindet, wobei vorzugsweise vorgesehen ist, dass es sich bei dem einen und bei dem anderen Bereich um Endbereiche der Kulisse der Halterung handelt.The backdrop of the holder or the bearing block can be designed such that the lever is in a region of the backdrop and the door in the closed position in a different area of the backdrop when the door is fully open, wherein it is preferably provided that it is in the one and the other area around end portions of the backdrop of the bracket.
Denkbar ist es, dass die Bewegung des Hebels in der Kulisse der Halterung durch eine Bremswirkung hervorgerufen wird, die der Hebel beim Bewegen der Tür in Schließrichtung erfährt. Die Bremswirkung kann durch einen Bereich des an der Tür angeordneten Moduls hervorgerufen werden, den der Hebel durchläuft.It is conceivable that the movement of the lever in the backdrop of the holder is caused by a braking effect that the lever undergoes when moving the door in the closing direction. The braking effect may be caused by a portion of the door-mounted module that the lever passes through.
Die vorgenannten Komponenten können bis auf die Halterung bzw. den Lagerbock Bestandteile eines Moduls sein, das sich an der Tür des Gerätes befindet. Das Modul kann ein Modulgehäuse aufweisen, in dem vorzugsweise die Schließeinheit bzw. der Dämpfer, der Gleitträger, der Sicherungsschieber und das Verriegelungselement angeordnet sind.The abovementioned components can be components of a module, which is located on the door of the device, except for the holder or the bearing block. The module may have a module housing, in which preferably the closing unit or the damper, the slide carrier, the safety slide and the locking element are arranged.
In dem Modulgehäuse kann sich die wenigstens eine Kulisse für den Hebel und/oder für das Verriegelungselement befinden.In the module housing, the at least one link for the lever and / or for the locking element can be located.
Vorzugsweise ist der Schließdämpfer als modulare Einheit ausgebildet, damit bei Anwendung mit weniger Dämpfungskraftbedarf, z.B. bei einer Gefrierteiltüre der Einsatz von einfacheren Dämpfern, wie z.B. Luftdämpfern möglich ist.Preferably, the closure damper is formed as a modular unit for use with less damping power requirements, e.g. in the case of a freezer door, the use of simpler dampers, e.g. Air dampers is possible.
Weiterhin kann durch die vorliegende Erfindung eine geräuscharme Türbewegung erreicht werden und die Mechanik kann weitgehend verborgen angeordnet sein, so dass sie für einen Nutzer möglichst wenig in Erscheinung tritt.Furthermore, a low-noise door movement can be achieved by the present invention and the mechanism can be arranged largely hidden, so that it occurs as little as possible for a user in appearance.
Weitere Vorteile und Einzelheiten der Erfindung werden anhand eines in der Zeichnung näher dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

Das Bezugszeichen 30 kennzeichnet einen Lagerbock, der an dem Korpus eines Kühl- bzw. Gefriergerätes mittels der Halterungen 36 festgelegt ist. Der ortsfeste Lagerbock 30 weist eine Halterung 32 zur Aufnahme der Lagerachse der Tür auf.The
Das Bezugszeichen 34 kennzeichnet eine Kulisse, die in dem Lagerbock 30 verläuft und in der bewegbar angeordnet der Stift 24 des Hebels 20 verläuft. Der Hebel 20 erstreckt sich zwischen dem Lagerbock 30 und dem Modulgehäuse 10 bzw. den darin befindlichen Komponenten. Wie dies aus
Die Bezugszeichen 12 und 14 kennzeichnen Kulissen in Form von Nuten, die in dem Modulgehäuse 10 angeordnet sind.

Wie dies aus dieser Figur hervorgeht, befindet sich in dem einen Endbereich des Modulsgehäuses 10 der Dämpfer 40, der beispielsweise als Öl-Luft-Dämpfer ausgeführt sein kann und eine geschwindigkeitsabhängige Dämpfung erzeugt. Die aufzubringende Dämpferenergie ist abhängig von Türschließgeschwindigkeit, Türöffnungsstellung, aus der die Türschließbewegung begonnen wird und auch von den Türmassen.As can be seen from this figure, located in the one end portion of the

Dann ist eine Bewegung des Hebels 20 relativ zu dem Verriegelungselement 70 und eine Relativbewegung zwischen Sicherungsschieber 60 und Verriegelungselement 70 möglich.The

Die Position der in
In dieser Position ist der Hebel 20 mit seinem Stift 22 durch das Verriegelungselement 70, d. h. durch die nach unten vorspringende Nase 72' an einer Bewegung relativ zu dem Verriegelungselement 70 bzw. relativ zu dem Gleitträger 50 gehindert.In this position, the

Bei einem Türöffnungswinkel von beispielsweise < 35 ° wird über eine Spiralfeder, die als Zug- oder Druckfeder ausgeführt sein kann und die im bzw. am Dämpfer 40 angeordnet sein kann, eine Zugkraft (gemäß der Figuren nach links) auf den Gleitträger 50 und auf das Verriegelungselement ("Steuerkralle"), das als Verbindungselement zwischen Hebel 20 und dem Gleitträger 50 bzw. dem Dämpfer 40 dient, aufgebracht.At a door opening angle of, for example, <35 ° is a helical spring, which can be designed as tension or compression spring and can be arranged in or on the
In dieser beispielsweise in
Wird die Tür geöffnet, so wird auf dem Auszugweg des Dämpfers 40 infolge der Türöffnung bis ca. 35 ° die genannte Feder weiter vorgespannt. Aus diesem Bereich wird die Steuerkralle bzw. das Verbindungselement 70 wegabhängig über die Steuerkurven 14, 14' im Modulgehäuse10 so gesteuert, dass ab einem bestimmten Weg der Hebel 20 die formschlüssige Verbindung mit dem Verriegelungselement 70 verlässt, d.h. der Hebel 20 ist dann unabhängig von dem Verriegelungselement 70 bewegbar.If the door is opened, so called spring is further biased on the Auszugweg of the
Der Hebel 20 steht ab dann außer Eingriff und ist kraftlos, was in anderen Worten bedeutet, dass die Tür ab diesem Öffnungswinkel (beispielsweise 35 °) nicht bewegt wird, da auf diese weder ein Schließ- noch ein Öffnungsmoment wirkt. Gleichzeitig wird über eine weitere Druckfeder 90 der angefederte Sicherungsschieber 60 über eine zweite Steuerkurve im Modulgehäuse in eine Position gebracht, in der die Steuerkralle bzw. das Verriegelungselement 70 in der Freigabeposition bzw. in der vorgespannten Stellung verriegelt wird. Dies verhindert eine unbeabsichtigte Rückstellung der unter Kraft stehenden Gleitträger-Verriegelungselement-Einheit.The
Erfolgt eine Türöffnungsbewegung, die einem kleineren Öffnungswinkel als beispielsweise 35 ° entspricht, findet dieses Lösen des Hebels 20 nicht statt, so dass eine entsprechend wirkende wegabhängige Zugkraft ein über die Hebelverbindung resultierendes Schließmoment auf die Türe ausübt und die Türe in ihrer Schließstellung bewegt wird.If a door opening movement, which corresponds to a smaller opening angle than, for example, 35 °, this release of the
Bei dem Dämpfer kann es sich um einen Öl-Luftdämpfer handeln oder auch um reinen Luftdämpfer, beispielsweise für Anwendungen an Geräten mit weniger Dämpfungskraftbedarf. Denkbar wäre hierzu ein Gefrierteil mit weniger Türmasse. In Betracht kommen auch andere kostengünstigere Dämpferlösungen, die entsprechenden Anforderungen genügen.The damper may be an oil-air damper or even pure air damper, for example, for applications on equipment with less damping power requirement. Conceivable this would be a freezer with less door mass. Other cost-effective damper solutions that meet the corresponding requirements are also possible.
Wird die Tür beispielsweise ausgehend von der in
Der Bremsbereich 80 kann über wenigstens ein Zusatzbauteil mit unterschiedlicher Bremswirkung (z. B. für unterschiedliche Türmassen) ausgelegt werden.The
Des Weiteren kann dieser über das Zusatzbauteil gestaltete Bremsbereich entlang seiner Länge (Bremsweg) mit unterschiedlichen Steifigkeiten (über geometrische Variationen oder über den Einsatz verschiedener Materialabschnitte) in unterschiedlichen Bremspositionen entsprechend mit bremswegabhängig angepasster Bremswirkung gestaltet werden.Furthermore, this braking area designed via the additional component can be designed along its length (braking distance) with different stiffnesses (via geometric variations or via the use of different material sections) in different braking positions corresponding to brake action-dependent adapted braking action.
Im Folge der weiteren Schließbewegung verbleibt der Stift 24 im Bereich A und trifft nach Verlassen des Bremsbereiches 80 auf das Verriegelungselement 70, das sich in seiner Freigabeposition befindet, da es dort durch den Sicherungsschieber 60 gehalten wird.As a result of the further closing movement, the
Der Sicherungsschieber 60 wird in der weiteren Bewegung des Hebels 20 als erstes so bewegt, dass die Steuerkralle bzw. das Verriegelungselement 70 entriegelt wird, d. h. den Stift 22 formschlüssig hintergreift. Auf diese Weise erhält der Sicherungsschieber 60 die Möglichkeit, sich aus der gesicherten vorgespannten Position herauszubewegen.The
Das Verriegelungselement 70 wird infolge der weiteren Hebelbewegung durch die Kulissenbahn 14, 14' aus der gesicherten vorgespannten Stellung bewegt. Auf diese Weise kommt das System aus Hebel 20 mit Gleitträger 50, Verriegelungselement 70 und Dämpfer 40 wieder in Eingriff.The locking
Der Dämpfer 40 kann somit seine Dämpfkraft dem Hebel 20 entgegenbringen, so dass die kinetische Energie der Türschlussbewegung gedämpft, d. h. reduziert bzw. vernichtet wird. Wie oben ausgeführt, erfolgt diese Dämpfung beispielsweise über den Einsatz eines Öl-Luftdämpfers geschwindigkeitsabhängig.The
Die aufzubringende Dämpfenergie ist abhängig von Türschlussgeschwindigkeit, Türöffnungsstellung, aus der die Türschließbewegung begonnen wird, und auch von der Türmasse. Um diesen sehr variablen Bedingungen gerecht zu werden, besitzt das System im Bereich < 35 °, d. h. das System befindet sich im Eingriff, beide funktionale Zustände (dämpfen und selbstschließen) wechselwirkend. Dies bedeutet, dass wenn die Bewegungsenergie der Tür vernichtet ist, automatisch die Selbstschließung in Kraft tritt und die Tür schließt, d. h. das System übt auf die Tür ein Schließmoment aus.The applied damping energy depends on the door closing speed, the door opening position from which the door closing movement is started, and also from the door mass. In order to cope with these very variable conditions, the system has in the range <35 °, ie the system is in engagement, both functional states (damping and self-closing) interacting. This means that when the kinetic energy of the door is destroyed, the self-closing automatically takes effect and closes the door, ie the system exerts a closing moment on the door.
An dieser Stelle wird darauf hingewiesen, dass die Winkelangaben von z.B. 35 ° oder 115 ° exemplarisch sind und die Erfindung nicht beschränken.It should be noted at this point that the angles of e.g. 35 ° or 115 ° are exemplary and not limit the invention.
Im vollständig geöffneten Zustand gemäß
In dieser Position befindet sich der Hebel 20 mit seinem Stift 22 im lagerbockseitigen Ende der Kulisse 80 und lagerbockseitig in der zum Türdrehpunkt 22 nahen Endbereich der Kulisse 34, d. h. im Bereich B. In dieser Position befindet sich das System Modul-Hebel-Lagerbock in Strecklage und ist auf Zug belastet. Um die Kulissenendpositionen noch dämpfend wirkend auszubilden, kann es sinnvoll sein und ist von der Erfindung mit umfasst, eine oder mehrere elastische Elemente vorzusehen, so dass die Anschlagsituation auch gedämpft wird.In this position, the
Durch adaptiv einsetzbare Zusatzteile, entweder in den modulgehäuseseitigen Kulissen oder in den Kulissen des Kulissenlagerblockes kann der maximal mögliche Türöffnungswinkel auf Kundenwunsch begrenzt werden.By adaptive usable additional parts, either in the module housing side scenes or in the scenes of the sliding block block the maximum possible door opening angle can be limited to customer requirements.
In einem Bereich z. B. zwischen 35 ° und 115 °, d. h. bis zum maximalen Türöffnungswinkel unterliegt die Tür keiner Kraftwirkung. Dies bedeutet, dass die Tür in der Stellung ohne Krafteinwirkung stehen bleibt, in der sie der Kunde bringt. Es wirken hierbei somit weder Öffnungs- noch Schließmomente.In an area z. B. between 35 ° and 115 °, d. H. up to the maximum door opening angle, the door is not subject to any force. This means that the door stops in the non-force position in which it is brought by the customer. Thus, neither opening nor closing moments act here.
