Description

Die vorliegende Erfindung betrifft ein Kältegerät mit einer Gefrierfachklappe oder einer Gefrierfachtür.The present invention relates to a refrigerator with a freezer compartment door or a freezer compartment door.

Die FR 2 336 859 A7 beschreibt ein Gefrierfach eines Kältegeräts, welches mit einer Tür verschließbar ist. Hierbei ist einstückig mit einem Griffteil, welches Lagerzapfen aufweist, ein elastisches Element ausgebildet. Das elastische Element sorgt dafür, dass ein Rastvorsprung des Griffteils in eine Falle eingreift, welche auf Seiten des mit der Tür verschließbaren Gefrierfachs vorgesehen ist.The FR 2 336 859 A7 describes a freezer of a refrigerator, which is closable with a door. Here, an elastic element is integrally formed with a handle part, which has bearing journals. The elastic element ensures that a latching projection of the handle part engages in a trap which is provided on the sides of the door closable with the freezer compartment.

Die EP 0 829 600 A1 beschreibt ein Kühlgerät mit einem Gefrierfach, dessen Tür durch Betätigen eines Griffteils entriegelt werden kann. Das Griffteil ist um eine durch zwei Lagerzapfen verlaufende Schwenkachse verschwenkbar, welche in Lagerösen aufgenommen sind. Die Lagerösen sind einstückig mit der Tür ausgebildet. Ein serpentinenförmige Windungen aufweisendes Federelement ist hierbei einstückig mit dem Griffteil ausgebildet.The EP 0 829 600 A1 describes a refrigerator with a freezer compartment, the door can be unlocked by pressing a handle. The grip part is pivotable about a pivot axis extending through two pivot pins, which are received in bearing eyelets. The eyelets are integrally formed with the door. A serpentine windings exhibiting spring element is in this case formed integrally with the handle part.

In einem Kältegerät wie etwa einem Kühlschrank mit integriertem Gefrierfach ist das Gefrierfach im Allgemeinen vom restlichen Innenraum durch eine schwenkbare Klappe oder eine Tür wärmeisolierend abgetrennt. Die Klappe oder die Tür hat einen beweglichen Rastvorsprung oder Riegel, der im geschlossenen Zustand in einen Haltevorsprung oder dgl. an einer Seitenwand des Innenbehälters einrastet und so die Klappe oder die Tür in der Schließstellung hält. Diese Einrastung soll trotz eventueller Abmessungstoleranzen des Innenbehälters zuverlässig möglich sein. Außerdem soll es mit einer Hand möglich sein, den Rastvorsprung aus der Aussparung zu lösen und die Klappe aufzuziehen. Eine bekannte Tür, die diese Anforderungen erfüllt, hat einen plattenartigen Türkörper, ein schwenkbares Griffteil, das einen sich an einer Vorderseite des Türkörpers der Tür erstreckenden ersten Schenkel und einen sich an der Seitenflanke des Grundkörpers erstreckenden zweiten Schenkel umfasst, und eine in einem Spalt zwischen der Seitenflanke und dem zweiten Schenkel untergebrachte, durch ein Schwenken des Griffteiles komprimierbare Feder, die den Rastvorsprung trägt, wobei der Rastvorsprung durch das Schwenken des Griffteiles auf die Seitenflanke zu verschiebbar und somit aus der Aussparung des Innenbehälters lösbar ist. Indem ein Benutzer durch Ziehen an dem ersten Schenkel das Griffteil schwenkt, kann er gleichzeitig eine Zugkraft zum Öffnen der Tür ausüben als auch die Verriegelung lösen.In a refrigerator such as a refrigerator with integrated freezer compartment, the freezer compartment is generally separated from the rest of the interior by a hinged flap or door to provide heat insulation. The flap or the door has a movable latching projection or latch which, in the closed state, engages in a retaining projection or the like on a side wall of the inner container and thus holds the flap or the door in the closed position. This latching should be reliably possible despite possible dimensional tolerances of the inner container. In addition, it should be possible with one hand to release the locking projection from the recess and raise the flap. A known door that meets these requirements has a plate-like door body, a pivotable handle portion comprising a first leg extending at a front of the door body of the door and a second leg extending at the side edge of the body, and one in a gap between the side flank and the second leg accommodated, by a pivoting of the handle portion compressible spring which carries the latching projection, wherein the latching projection by the pivoting of the handle part on the side edge to be displaced and thus from the recess of the inner container is detachable. By a user by pulling on the first leg pivots the handle portion, he can simultaneously exert a pulling force to open the door and release the lock.

An der Feder angeformte Zapfen greifen in Öffnungen sowohl des Griffteiles als auch des Grundkörpers ein und definieren so die Schwenkachse des Griffteiles.Pins molded onto the spring engage in openings in both the grip part and the base body and thus define the pivot axis of the grip part.

Ein derartiges Kältegerät ist beispielsweise aus der FR 2 367 176 A1 bekannt. Die FR 2 367 176 A1 beschreibt nämlich ein Kältegerät mit einem Gefrierfach, welches mittels einer Tür verschlossen werden kann. Ein Griffteil und ein Riegel sind als voneinander separate Bauteile ausgebildet, wobei das Griffteil winkelförmig ausgebildet ist und einen sich an der Vorderseite der Tür erstreckenden ersten Schenkel und einen sich an einer Seitenflanke der Tür erstreckenden zweiten Schenkel umfasst. Der Riegel ist einstückig mit zwei Federn ausgebildet, welche in einem Raum zwischen der Seitenflanke der Tür und dem kürzeren Schenkel des Griffteils untergebracht sind. Der Riegel weist einen durch das Schwenken des Griffteils zur Seitenflanke der Tür bewegbaren Rastvorsprung auf. Der Riegel weist des Weiteren zwei Lagerzapfen auf, welche in Ösen an der Stirnseite der Tür aufgenommen sind. Die Lagerzapfen bilden zugleich eine Schwenkachse für das Griffteil, welches hierfür zwei Halteösen aufweist, durch welche die Lagerzapfen hindurchtreten.Such a refrigeration device is for example from the FR 2 367 176 A1 known. The FR 2 367 176 A1 Namely, describes a refrigerator with a freezer compartment, which can be closed by a door. A handle part and a latch are formed as separate components, wherein the handle part is formed angularly and comprises a front leg extending to the first leg and extending on a side edge of the door second leg. The latch is integrally formed with two springs, which are housed in a space between the side edge of the door and the shorter leg of the handle portion. The bolt has a movable by pivoting the handle portion to the side edge of the door latching projection. The bolt further comprises two bearing journals, which are received in eyelets on the front side of the door. The journals at the same time form a pivot axis for the handle part, which for this purpose has two grommets, through which the bearing pins pass.

Bei unvorsichtiger Handhabung ist es möglich, dass beim Öffnen der Tür erhebliche Scherkräfte auf die Zapfen einwirken, die das Federmaterial strapazieren und im Laufe der Zeit zum Brechen der Zapfen führen können.Careless handling, it is possible that when you open the door considerable shear forces acting on the pins that can stress the spring material and can lead over time to break the pin.

Es besteht daher Bedarf nach einer Klappe oder einer Tür der oben genannten Art, bei der die Gefahr eines Bruchs der Zapfen verringert ist.There is therefore a need for a flap or a door of the above type, in which the risk of breakage of the pin is reduced.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass Türkörper und Griffteil quer zur Schwenkachse orientierte erste und zweite Vorsprünge aufweisen, wobei die ersten Vorsprünge jeweils einen Zapfen tragen und die zweiten Vorsprünge eine Öffnung aufweisen, in die einer der Zapfen die Schwenkachse definierend eingreift. Zur Befestigung der Feder an der Klappe oder der Tür weist die Feder an zwei in Richtung der Schwenkachse beabstandeten Enden jeweils einen Vorsprung auf, der in eine Öffnung des Grundkörpers oder des Griffteiles eingreift. Dabei sind die Vorsprünge und Öffnungen vorzugsweise so platziert, dass die Schwenkachse durch die Öffnungen verläuft. Die Zapfen sind also nicht mehr zusammenhängend mit der Feder ausgeführt, sondern zusammenhängend mit entweder dem Griffteil oder dem Türkörper der Klappe oder der Tür, die aus belastbarerem, weniger ermüdungsgefährdeten Materialien als die Feder gefertigt sein können.The object is achieved in that door body and handle portion transverse to the pivot axis oriented first and second projections, wherein the first projections each carry a pin and the second projections have an opening into which one of the pins engages the pivot axis defining. For fixing the spring to the flap or the door, the spring has two projections spaced from each other in the direction of the pivot axis, in each case a projection which projects into an opening engages the body or the handle part. In this case, the projections and openings are preferably placed so that the pivot axis extends through the openings. The pins are thus no longer integral with the spring, but contiguous with either the handle portion or the door body of the flap or door, which may be made of stronger, less fatigued materials than the spring.

Um ein Einrasten der Zapfen in die Öffnungen zu ermöglichen, ist vorzugsweise wenigstens eine der Wandflächen in Richtung der Achse elastisch auslenkbar.In order to enable engagement of the pins in the openings, preferably at least one of the wall surfaces in the direction of the axis is elastically deflectable.

Die Feder hat vorzugsweise senkrecht zu der Schwenkachse einen haarnadelförmigen Querschnitt mit an einem Scheitel zusammenhängenden Schenkeln. Diese Schenkel werden beim Schwenken des Griffteiles elastisch gegeneinander gedrückt.The spring preferably has a hairpin-shaped cross section with legs connected to a vertex perpendicular to the pivot axis. These legs are pressed elastically against each other during pivoting of the handle part.

Um eine gute Federwirkung mit einem kompakten Aufbau zu erreichen, sollte die Schwenkachse näher an dem Scheitel als an den von dem Scheitel entfernten Enden der Schenkel verlaufen.In order to achieve a good spring action with a compact construction, the pivot axis should run closer to the apex than at the ends of the legs remote from the apex.

Besonders bevorzugt verläuft die Schwenkachse zwischen den Schenkeln der Feder.Particularly preferably, the pivot axis extends between the legs of the spring.

Um das Griffteil entlang der Schwenkachse gleichmäßig zu versteifen, kann ein quer zur Schwenkachse orientiertes, die zwei Schenkel des Griffteiles verbindendes Wandstück vorgesehen sein, das sich durch einen Schlitz wenigstens eines in Richtung der Schwenkachse langgestreckten Schenkels der Feder erstreckt.To uniformly stiffen the handle along the pivot axis, a transverse to the pivot axis, the two legs of the handle portion connecting wall piece may be provided which extends through a slot at least one elongated in the direction of the pivot axis leg of the spring.

Um die Vorsprünge leicht in den Öffnungen verrasten zu können, sind sie zweckmäßigerweise mit einem Hauptteil der Feder in Richtung der Schwenkachse elastisch bewegbar verbunden. Eine elastische Anbindung der Vorsprünge an das Hauptteil kann auf einfache Weise geschaffen werden, indem der Schenkel der Feder durch einen Schlitz in besagten Hauptteil und einen an einem Ende mit dem Hauptteil verbundenen Arm unterteilt ist und dass einer der Vorsprünge an dem anderen Ende des Arms gebildet ist.In order to easily lock the projections in the openings, they are advantageously connected elastically movable with a main part of the spring in the direction of the pivot axis. An elastic connection of the projections to the main part can be provided in a simple manner by the leg of the spring is divided by a slot in said main part and an arm connected at one end to the main part and that one of the projections formed at the other end of the arm is.

Fig. 1 zeigt in perspektivischer Ansicht die erfindungsgemäße Gefrierfachtür, die zum. Verschließen eines Gefrierfachs dient, das z.B. vom Innenraum eines Kühlschrank abgeteilt ist. Die im vorliegenden Fall als Tür ausgebildete Klappe umfasst einen im Wesentlichen rechteckig plattenförmigen Türkörper 1. Der Türkörper 1 hat horizontale obere und untere Flanken, von denen in der Nähe ihres rechten Randes jeweils ein zylindrischer Zapfen 2 absteht. Die in Aussparungen eines (nicht dargestellten) Korpus des Kühlschranks eingreifenden Zapfen 2 legen eine vertikale Schwenkachse der Klappe fest. Es versteht sich jedoch, dass der im Folgenden beschriebene Aufbau der Tür auch ohne Weiteres auf eine Klappe mit horizontaler Schwenkachse übertragbar ist. Fig. 1 shows a perspective view of the freezer compartment door according to the invention, the. Closing a freezer compartment is used, for example, is separated from the interior of a refrigerator. The flap designed as a door in the present case comprises a substantially rectangular plate-shaped door body 1. The door body 1 has horizontal upper and lower flanks, from each of which a cylindrical pin 2 projects in the vicinity of its right edge. The recesses of a (not shown) body of the refrigerator engaging pin 2 set a vertical pivot axis of the flap firmly. It is understood, however, that the structure of the door described below can also be easily transferred to a flap with a horizontal pivot axis.

An der Vorderseite des Türkörpers 1 ist eine zu deren von den Zapfen 2 abgewandtem Rand hin offene Nische 3 gebildet, die einen ersten Schenkel 4 eines an den Türkörper angelenkten Griffteiles 5 aufnimmt. Wie in dem Schnitt der Fig. 2 zu sehen, ist die Nische 3 in ihrem von dem Rand abgewandten Bereich tiefer, als der Wandstärke des Schenkels 4 entspricht, so dass ein Benutzer in die Nische 3 eingreifen und den ersten Schenkel 4. des Griffteiles 5 leicht an seiner Rückseite fassen und vorziehen kann.At the front of the door body 1, a niche 3 open towards the edge remote from the pins 2 is formed, which receives a first leg 4 of a handle part 5 hinged to the door body. As in the section of the Fig. 2 can be seen, the niche 3 is deeper in their remote from the edge region, as the wall thickness of the leg 4 corresponds, so that a user can engage in the niche 3 and the first leg of the handle portion 4 5 easily grasp and prefer on his back ,

Ein zweiter Schenkel 6 des Griffteiles 5 erstreckt sich senkrecht zum ersten Schenkel 4, wobei er zusammen mit einer seitlichen Flanke 7 des Grundkörpers einen Zwischenraum 8 begrenzt.A second leg 6 of the handle portion 5 extends perpendicular to the first leg 4, wherein it defines a gap 8 together with a lateral edge 7 of the base body.

Wie in Fig. 3 gezeigt, ist das einteilig spritzgeformte Griffteil 5 durch eine Mehrzahl von als Wandflächen 9, 10, 11 ausgebildeten Vorsprüngen versteift, die die beiden Schenkel 4, 6 verbinden und in etwa senkrecht zu diesen orientiert sind. Die in der Perspektive der Fig. 3 zuoberst bzw. zuunterst liegenden Wandstücke 9 haben jeweils eine kreisrunde Öffnung 12, die vorgesehen ist, um einen mit dem Grundkörper 1 verbundenen Zapfen 13 aufzunehmen und so die Schwenkachse des Griffteiles 5 festzulegen. Wie Fig. 6 zeigt, befinden sich diese Zapfen 13 jeweils an den Enden von zwei als Vorsprünge dienende Zungen 14, die von der seitlichen Flanke 7 des Grundkörpers 1 abstehen. Wie in Fig. 6 am Beispiel des unteren Zapfens 13 dargestellt, kann wenigstens einer dieser Zapfen 13 eine abgeschrägte Stirnseite 15 aufweisen, die die Montage des Griffteiles 5 durch Überschieben eines der Wandstücke 9 über diese Stirnseite 15 bei gleichzeitiger elastischer Auslenkung der Zungen 14 erlaubt.As in Fig. 3 shown, the one-piece injection-molded handle part 5 is stiffened by a plurality of wall surfaces 9, 10, 11 formed as projections which connect the two legs 4, 6 and are oriented approximately perpendicular to this. The in the perspective of Fig. 3 Uppermost or lowermost wall pieces 9 each have a circular opening 12 which is provided to receive a pin 13 connected to the base body 1 and thus fix the pivot axis of the handle part 5. As Fig. 6 shows, these pins 13 are respectively at the ends of two tongues 14 serving as projections, which protrude from the lateral edge 7 of the main body 1. As in Fig. 6 illustrated by the example of the lower pin 13, at least one of these pins 13 may have a beveled end face 15, which allows the assembly of the handle part 5 by sliding over one of the wall pieces 9 via this end face 15 with simultaneous elastic deflection of the tongues 14.

In dem Zwischenraum 8 zwischen der seitlichen Flanke 7 des Grundkörpers 1 und dem Schenkel 6 ist eine in Fig. 2 im Schnitt gezeigte Feder 16 untergebracht. Die Feder 16 hat eine haarnadelartige Gestalt mit einem an der Flanke 7 anliegenden ersten Schenkel 17 und einem an dem Schenkel 6 des Griffteiles 5 anliegenden zweiten Schenkel 18, die an einem gekrümmten Scheitel 19 miteinander verbunden sind. Die Feder 16 treibt die Flanke 7 und den zweiten Schenkel 6 des Griffteils 5 auseinander, so dass dessen erster Schenkel im Ruhezustand in die Nische 3 eintaucht und seine Außenseite mit der Vorderseite des Grundkörpers 1 bündig ist.In the intermediate space 8 between the lateral edge 7 of the main body 1 and the leg 6 is an in Fig. 2 shown in section spring 16 housed. The spring 16 has a hairpin-like shape with a voltage applied to the edge 7 first leg 17 and a voltage applied to the leg 6 of the handle portion 5 second leg 18 which are connected to one another at a curved vertex 19. The spring 16 drives the flank 7 and the second leg 6 of the handle part 5 apart, so that the first Leg immersed in the state of rest in the niche 3 and its outside is flush with the front of the body 1.

Die von den Öffnungen 12 und Zapfen 13 festgelegte Drehachse 20 verläuft zwischen den Schenkeln 17, 18 in der Nähe des Scheitels 19. An einem von dem Scheitel 19 abgewandten Ende des zweiten Schenkels 18 ist ein Rastvorsprung 21 gebildet, der von der seitlichen Flanke 7 fort über den Schenkel 6 des Griffteiles 5 hinaus übersteht. Der Rastvorsprung 21 hat eine abgeschrägte Flanke 22, die, wenn die Klappe in einen. Rahmen hineingedrückt wird, zur Flanke 7 hin zurückweicht und, sobald sie in dem Rahmen auf eine Aussparung stößt, getrieben durch die Kraft der Feder 16 in die Aussparung einrückt und so die Klappe verriegelt. Das Zurückweichen des Rastvorsprunges 21 ist selbst dann möglich, wenn ein Benutzer die Kraft zum Schließen der Klappe durch Drücken auf den Schenkel 4 des Griffteiles 5 ausübt.The axis of rotation 20 defined by the openings 12 and pins 13 extends between the legs 17, 18 in the vicinity of the apex 19. At one end of the second leg 18 facing away from the apex 19, a latching projection 21 is formed which extends away from the lateral flank 7 beyond the leg 6 of the handle part 5 also protrudes. The latching projection 21 has a chamfered edge 22, which, when the flap in a. Frame is pushed in, back to the flank 7 back and, as soon as it encounters a recess in the frame, driven by the force of the spring 16 engages in the recess and locks the flap. The retraction of the locking projection 21 is possible even when a user exerts the force to close the flap by pressing on the leg 4 of the handle part 5.

Wenn der Benutzer am Schenkel 4 zieht, um die klappe zu öffnen, schwenkt das Griffteil 5 um die Drehachse 20 in eine in Fig. 2 als gestrichelter Umriss dargestellte Stellung, in welcher die Feder 16 von dem Schenkel 6 gegen die Flanke 7 des Türkörpers 1 gedrückt und der Rastvorsprung 21 aus der Aussparung herausgezogen ist. In dieser Stellung kann die Klappe geöffnet werden.When the user pulls on the leg 4 to open the flap, the handle part 5 pivots about the axis of rotation 20 in an in Fig. 2 shown as a dashed outline position in which the spring 16 is pressed by the leg 6 against the edge 7 of the door body 1 and the locking projection 21 is pulled out of the recess. In this position, the flap can be opened.

Die Gestalt der Feder ist genauer gezeigt in der perspektivischen Ansicht der Fig. 4. Hier erkennt man, dass die zwei Schenkel 17, 18 und der Rastvorsprung 21 jeweils in Richtung der Drehachse langgestreckte, plattenförmige Teile sind, wobei der Schenkel 17 entlang der Drehachse 20 ausgedehnter ist als der Schenkel 18 und durch zwei Schlitze 23 in ein Hauptteil 24 und zwei Arme 25 unterteilt ist, die mit dem Hauptteil 24 in Höhe von dessen vom Scheitel 19 abgewandten Ende zusammenhängen und in Höhe des Scheitels 19 jeweils einen zu der Drehachse 20 parallelen Zapfen 26 tragen. Die Elastizität des Materials der Feder 16 sowie das Vorhandensein der Schlitze 23 ermöglicht es, die Zapfen 26 elastisch aufeinander zu zu bewegen, um sie so in Öffnungen 27 der Wandstücke 11 einzurasten. Fig. 5 zeigt die Feder 16 im am Griffteil 5 montierten Zustand. Die Wandstücke 11 erstrecken sich nun durch die Schlitze 23. Die Montage des Griffteiles 5 am Grundkörper 1 erfolgt erst nach Anbringung der Feder 16. Die Zapfen 26 liegen zwar bei diesem Aufbau auf der Drehachse 20, doch ist die Feder 16 an der Führung der Schwenkbewegung des Griffteiles 5 in Bezug auf den Türkörper 1 nicht beteiligt. Scherkräfte, die auftreten, wenn das Griffteil 5 bis zu einer Anschlagstellung geschwenkt ist, in der die zwei Schenkel 17, 18 der Feder 16 einander berühren, werden von den Zapfen 13 und den Zungen 14 aufgenommen, die, da sie beim Gebrauch der Klappe nicht ständig einer elastischen Verformung ausgesetzt sind, aus einem gegenüber diesen Scherkräften widerstandsfähigeren Material als dem der Feder 16 gebildet sein können.The shape of the spring is shown in more detail in the perspective view of Fig. 4 , Here it can be seen that the two legs 17, 18 and the locking projection 21 are each in the direction of the axis of rotation elongated plate-shaped parts, wherein the leg 17 along the axis of rotation 20 is more extensive than the leg 18 and through two slots 23 in a main part 24 and two arms 25 is divided, which are related to the main part 24 at the level of its end facing away from the apex 19 and carry at the height of the apex 19 each a parallel to the axis of rotation 20 pin 26. The elasticity of the material of the spring 16 and the presence of the slots 23 makes it possible to elastically move the pins 26 towards each other so as to lock them into openings 27 of the wall pieces 11. Fig. 5 shows the spring 16 in the mounted on the handle part 5 state. The wall pieces 11 now extend through the slots 23. The assembly of the handle part 5 on the base body 1 takes place only after attachment of the spring 16th Although the pins 26 are in this structure on the axis of rotation 20, but the spring 16 is not involved in the leadership of the pivotal movement of the handle part 5 with respect to the door body 1. Shearing forces that occur when the handle portion 5 is pivoted to a stop position in which the two legs 17, 18 of the spring 16 contact each other, are taken up by the pins 13 and the tongues 14, since they are not in the use of the flap are constantly subjected to elastic deformation, can be formed from a relative to these shear forces more resistant material than that of the spring 16.
