- the object of the present invention is to provide a household appliance in which the functionality and flexibility of the storage device can be increased, but at the same time a reliable and durable storage device is provided.
- the present invention is disclosed in independent claim 1. Further embodiments are disclosed in the dependent claims. This object is achieved by providing in a household appliance mentioned above, that the bearing device has a radially outside of the bearing surface arranged anti-rotation device for non-rotatable connection of the bearing bush with the bearing pin. The rotation thus prevents rotation of the bearing bush relative to the bearing pin with respect to the pivot axis.
- the VeFE is arranged radially outside of the bearing surface, that is arranged with respect to the pivot axis of the bearing device outside the bearing surface, on the one hand creates a very effective and stable rotationally fixed connection of bearing bush and journal.
- torques acting on the bearing bush due to the radial distance of the rotation against the pivot axis and thus resulting lever can be very effectively absorbed.
- an anti-rotation which is relative to the pivot axis radially within the bearing surface, thus higher torques can be taken at comparable dimensioning of the anti-rotation or at comparable operating load, the life can be increased.
- the anti-rotation device according to the invention can be designed to be more compact with respect to anti-rotation devices arranged radially inside the bearing surface.
- the anti-rotation device also allows the area radially within the bearing surface can be made more free: since this area is no longer needed to form an anti-rotation, the bushing can be better to eg production requirements, especially when manufactured by plastic injection, optimized and / or this area can be optimally adapted to the requirements arising from the reception of the trunnion.
- the region lying radially within the bearing surface can now also be used for other components or functions. Thus, a receptacle for a leveling foot can be created in this area and / or supply lines can be carried out.
- the body of the household appliance according to the invention has, insofar as it is a household refrigeration appliance, an inner container which forms a boundary of the storage space for the refrigerated goods, an outer lining which forms an outer boundary of the household refrigerator, and an insulation layer introduced between the inner container and the outer lining.
- the insulating layer is preferably provided by insulating foam, e.g. expanded polyurethane foam, formed.
- the household appliance according to the invention has at least one door leaf rotatable about a pivot axis relative to the body for selectively closing and opening the storage space. Each door leaf is struck at least over two storage devices on the body. In this case, the bearing device on the inner container, on parts of the outer lining, such. End strips, or combinations thereof be attached.
- the storage device according to the invention can in principle be used as an upper or lower door storage.
- the bearing bush provides with its bearing surface a part of a plain bearing, over which the door leaf can be rotated relative to the body.
- the bearing surface is formed by an outer circumferential surface of a circular cylindrical portion of the bearing bush.
- the door leaf has as a complementary component of the sliding bearing on a geometrically adapted to the bearing surface bearing sleeve.
- the bearing sleeve has a bearing surface as an inner circumferential surface of a circular cylindrical bore.
- the bearing sleeve is preferably integrated in an upper or lower door closure strip of the door leaf, either as a separate component or integrally formed with the door closure strip.
- the bearing sleeve is preferably formed by a blind hole.
- the bearing sleeve is a plastic component.
- the geometry of the journal can be virtually arbitrary - it is only limited by the fact that the bearing bush must be able to be plugged onto the journal.
- the bearing journal with an end portion have rectangular, for example, square, cross-section, on which the bearing bush is fitted with a geometrically correspondingly adapted recording.
- the bearing bush may have an insertion bevel at the door leaf end facing the bearing surface.
- a frusto-conical end section can follow the circular-cylindrical section.
- the journal and the bushing are two separate components, which after the bushing has been placed on the journal, preferably non-destructive can be separated from each other again.
- the rotationally fixed connection of the bearing bush and bearing journal caused by the rotation lock can be formed by positive locking, by frictional engagement, by frictional connection or combinations thereof. Preference is given to a rotation formed by positive locking, since it can be very easy to assemble or disassemble.
- the anti-twist device can also optionally provide the degree of freedom of a longitudinal displacement of the bearing bush and the bearing journal, e.g. along the pivot axis, obstruct one or both sides.
- the rotation is to hinder only the degree of freedom of rotation; this allows an optimally designed against rotation, while the degree of freedom of the longitudinal displacement can otherwise be hindered.
- the journal is connected according to the invention by means of a bearing arm with the body.
- the bearing arm can protrude from the body in such a way that the pivot axis is spaced correspondingly far from the body.
- the bearing arm can be formed by an elongated member, sitting at the first end of the bearing pin and which is connected at its second end to the body.
- the bearing arm may preferably have at the second end a retaining tab which engages in a corresponding retaining opening of the body.
- the Have storage arm on one or more mounting holes, by means of which the bearing arm can be permanently attached by fasteners such as screws on the body.
- the body has appropriate fastening receptacles for this purpose.
- the bearing arm may further comprise a positioning pin, by means of which the exact position of the bearing arm is fixed relative to the body before the bearing arm, for example by means of the fastening means, is secured to the body;
- the body has a corresponding positioning receptacle.
- the journal and the bearing arm are integrally formed, preferably this combined metal component, e.g. a stamped bent part or a diecasting part.
- the bearing bush is a plastic component, e.g. an injection molded part.
- the anti-rotation is formed on a bearing pin holding the bearing arm and arranged on the bearing bush radially projecting apron, so that a very simple and with respect to the rotationally fixed connection is very effective, since there is direct acting structure.
- the skirt is only in a radial direction, in particular directly from the bearing surface, i. There is also a very compact structure.
- the skirt protrudes radially in the direction of a longitudinal extent of the bearing arm.
- the bearing arm in a sectional view perpendicular to the pivot axis on a plane of symmetry, which is in this case at the same time a plane of symmetry of the skirt, preferably the complete bearing bush.
- the skirt is integrally formed on the bearing bush, so it forms part of the bearing bush, so that a stable structure and a simple production results.
- a pin protruding from the skirt engages in a receptacle of the bearing arm.
- This pin is advantageously formed integrally with the skirt.
- the pin may be solid or hollow, in particular be formed with a blind hole.
- the inclusion of the bearing arm can through a hole, eg through or blind hole, or at plugged bearing bush are formed by lying next to the pin projections of the bearing arm.
- the pin is arranged in a sectional view perpendicular to the pivot axis within an edge region of the skirt. The joint of pin and receptacle can thereby be protected from contamination, as it is covered by the apron, and the storage device to be cleaned more easily.
- a relative to the pivot axis between pins and recording existing radial clearance is greater than a relation to the pivot axis between pins and recording existing tangential, in particular that the radial clearance is formed by a clearance and the Tangentialspiel by a press fit.
- the radial clearance refers to the game, which has the pin in a sectional view perpendicular to the pivot axis along a radial connecting line between the journal center and pivot axis with respect to the recording.
- the tangential game refers to the game, which has the pin in this sectional view perpendicular to the radial clearance relative to the recording.
- the larger radial clearance compensate for any manufacturing tolerances with respect to the position of the journal.
- the bearing pin is made integral with the bearing arm as a stamped and bent part
- the position of the journal in the radial direction relative to the pivot axis may vary slightly from component to component, which can be compensated by the radial clearance, without causing radial loads on the rotation ,
- the precise effect of the anti-rotation device is not affected by the greater radial play. If the tangential play is carried out as a press fit, there is also a captive unit of bearing bush and bearing pin, whereby the assembly is simplified.
- the different sized radial and tangential play can be achieved according to an embodiment in that the receptacle has a circular cross-section and the pin has a substantially elliptical or Gothic cross-section. It is exploited that a recording with circular cross-section can be made simple yet precise, eg by punching without post-processing of the bearing arm. The more complex shape of the pin, however, can be easily realized on the bearing bush be, for example by injection molding.
- the cross section of the pin is formed by a sectional plane perpendicular to the longitudinal extent of the elongated pin.
- This cross-section is preferably mirror-symmetrical in each case with respect to two axes of symmetry and has a larger first extent oriented substantially tangentially to the pivot axis as a second extent oriented essentially radially to the pivot axis. This is achieved by appropriate alignment of the elliptical or Gothic cross-section.
- the gothic cross-section is based on an elliptical cross-section, however, has kink points in the two main vertices.
- the receptacle can be formed by a slot and the pin have a circular cross-section. This allows a very large value of the radial clearance and at the same time, the pin can have a high strength by an undiminished large circular cross-section.
- the longitudinal extension of the elongated hole extends in a sectional view perpendicular to the longitudinal extension of the pin substantially radially with respect to the pivot axis.
- the skirt is arranged on a side facing away from the door leaf end of the bearing bush, so that the bearing bush largely, in particular the bearing surface and an optional insertion, can be completely accommodated in a corresponding bearing sleeve of the door leaf. This leads to a compact construction.
- a surface of the apron facing the door leaf is axially free relative to a substantially annular support surface of the bearing bush with respect to the pivot axis.
- the guide of the door leaf is thus exclusively on the bearing surface of the bearing bush, the support surface of the bearing bush and a bearing surface within the door leaf.
- the apron is thus not directly applied to the weight of the door leaf.
- the apron can serve indirectly, for example via the support surface, to dissipate absorbed weight forces from the bearing bush to other components.
- the bearing bush extends over an up to under the skirt extending support surface supported on a bearing arm.
- the total available area for supporting the bushing can be increased thereby, whereby the stability of the bearing device is improved.
- the bearing bush is supported on a flat and perpendicular to the pivot axis surface portion of a surface of the bearing arm.
- the skirt in a sectional view perpendicular to the pivot axis does not project beyond the bearing arm. There is thus a compact structure and the apron can be better protected against damage.
- the bearing journal has a rectangular cross-section and is seated in a form-fitting manner in an opening of the bearing bush. It is possible that the opening of the bearing bush is designed corresponding to the rectangular shape of the journal, in particular in a sectional view perpendicular to the pivot axis completely surrounds the bearing journal. It is also conceivable that the bearing journal is held only at two diagonally opposite, several or all four corners and / or two or more of its side edges by corresponding areas of the opening, whereby the area within the storage area can be used as possible for other components. It is possible in particular that the opening in a sectional view perpendicular to the pivot axis receives the bearing pin via a clearance fit. Because of the anti-rotation device according to the invention namely a narrow tolerances, especially achieved by press-fitting, guiding the trunnion in the opening of the bearing bush is not necessary or to avoid due to a possible overdetermination.
- the opening is arranged eccentrically with respect to the pivot axis.
- the opening is arranged radially opposite the skirt, so that the bearing bush can be supported on the bearing arm over the largest possible bearing surface by positioning the bearing bush far in the direction of the longitudinal extent of the bearing arm or in the direction of the body ,
- the bearing bush has a bore for receiving a shank of a leveling foot.
- this bore is off-center with respect to the pivot axis, further preferably in this case, the opening for receiving the journal is off-center, so that the area can be utilized in the best possible way within the storage area.
- a rotational axis of the bore is parallel to a rotational axis of the opening, more preferably, however, both axes are not adjacent to each other.
- the bore preferably has a constant cross-section, but may intersect with the opening such that bore and opening are interconnected.
- a bearing arm has at least one adjustable foot receptacle for receiving a shank of an adjustable foot, preferably that the bearing arm has at least two Stellfuß techniquen for receiving a shank of a adjustable foot and one of Stellfuß techniquen aligned with the bore of the bearing bush.
- the adjustable foot receptacle (s) of the bearing arm is or are bores, preferably provided with a thread, in order to be able to screw in the adjustable foot. In the event that the bearing arm has two corresponding Stellfuß techniquen, the position of the adjustable foot can be changed.
- a position of the adjustable foot can be selected closer to the body, so that under certain circumstances the leveling foot lies completely underneath the carcass; the area of the floor under the door leaf on which the appliance is standing can thus be cleaned more easily.
- the door leaf has a relatively large weight, can be selected as the position of the adjustable foot Stellfuß technique in the bearing arm, which is aligned with the bore in the bearing bush. The bending moment acting on the bearing arm can in this case be reduced or almost completely eliminated.
- the bearing pin protrudes substantially perpendicularly from a bearing arm.
- the bearing pin formed integrally on the bearing arm.

Die Erfindung betrifft ein Haushaltsgerät, insbesondere Haushaltskältegerät, aufweisend einen Korpus, einen im Korpus angeordneten Lagerraum und ein zum Öffnen und Schließen des Lagerraums ausgebildetes Türblatt, das schwenkbar bezüglich des Korpus mittels wenigstens einer Lagervorrichtung gelagert ist, die einen Lagerzapfen und eine auf den Lagerzapfen aufgesteckte, eine konzentrisch zu einer Schwenkachse der Lagervorrichtung angeordnete Lagerfläche aufweisende Lagerbuchse besitztThe invention relates to a household appliance, in particular domestic refrigeration appliance, comprising a body, a storage space arranged in the body and a trained for opening and closing the storage room door leaf which is pivotally mounted relative to the body by means of at least one bearing device, which mounted a bearing pin and a mounted on the journal , Has a concentric with a pivot axis of the bearing device arranged bearing surface having bearing bush
Die Aufgabe der vorliegenden Erfindung ist es, ein Haushaltsgerät bereitzustellen, bei dem die Funktionalität und Flexibilität der Lagervorrichtung erhöht werden kann, gleichzeitig jedoch eine zuverlässige und langlebige Lagervorrichtung geschaffen wird.The object of the present invention is to provide a household appliance in which the functionality and flexibility of the storage device can be increased, but at the same time a reliable and durable storage device is provided.
Die vorliegende Erfindung ist im unabhängigen Anspruch 1 offenbart. Weitere Ausgestaltungen sind in die abhängigen Ansprüchen offenbart. Diese Aufgabe wird erfindungsgemäß gelöst, indem bei einem eingangs erwähnten Haushaltsgerät vorgesehen wird, dass die Lagervorrichtung eine radial außerhalb der Lagerfläche angeordnete Verdrehsicherung zur drehfesten Verbindung der Lagerbuchse mit dem Lagerzapfen aufweist. Die Verdrehsicherung verhindert also ein Verdrehen der Lagerbuchse gegenüber dem Lagerzapfen bezüglich der Schwenkachse.The present invention is disclosed in
Indem die Vedrehsicherung radial außerhalb der Lagerfläche angeordnet ist, also bezüglich der Schwenkachse der Lagervorrichtung außerhalb der Lagerfläche angeordnet ist, entsteht einerseits eine sehr wirksame und stabile drehfeste Verbindung von Lagerbuchse und Lagerzapfen. So können auf die Lagerbuchse einwirkende Drehmomente aufgrund der radialen Entfernung der Verdrehsicherung zur Schwenkachse und des somit entstehenden Hebels sehr effektiv aufgenommen werden. Gegenüber einer Verdrehsicherung, die bezogen auf die Schwenkachse radial innerhalb der Lagerfläche liegt, können somit bei vergleichbarer Dimensionierung der Verdrehsicherungen höhere Drehmomente aufgenommen werden bzw. bei vergleichbarer Betriebsbelastung, die Lebensdauer erhöht werden. Umgekehrt kann bei vorgegebener Lebensdauer bzw. vorgegebener Betriebsbelastung die erfindungsgemäße Verdrehsicherung gegenüber radial innerhalb der Lagerfläche angeordneten Verdrehsicherungen kompakter konzipiert werden.By the Vedrehsicherung is arranged radially outside of the bearing surface, that is arranged with respect to the pivot axis of the bearing device outside the bearing surface, on the one hand creates a very effective and stable rotationally fixed connection of bearing bush and journal. Thus, torques acting on the bearing bush due to the radial distance of the rotation against the pivot axis and thus resulting lever can be very effectively absorbed. Opposite an anti-rotation, which is relative to the pivot axis radially within the bearing surface, thus higher torques can be taken at comparable dimensioning of the anti-rotation or at comparable operating load, the life can be increased. Conversely, for a given service life or predetermined operating load, the anti-rotation device according to the invention can be designed to be more compact with respect to anti-rotation devices arranged radially inside the bearing surface.
Andererseits ermöglicht die erfindungsgemäße Verdrehsicherung auch, dass der Bereich radial innerhalb der Lagerfläche freier gestaltet werden kann: da dieser Bereich nun nicht mehr zur Ausbildung einer Verdrehsicherung benötigt wird, kann die Lagerbuchse besser an z.B. fertigungstechnische Erfordernisse, insbesondere beim Herstellen durch Kunststoffspritzguß, optimiert werden und/oder dieser Bereich kann optimal an die durch die Aufnahme des Lagerzapfens entstehenden Erfordernisse angepasst werden. Darüber hinaus kann der radial innerhalb der Lagerfläche liegende Bereich nun auch für andere Bauteile bzw. Funktionen genutzt werden kann. So kann in diesem Bereich eine Aufnahme für einen Stellfuß geschaffen werden und/oder es können Versorgungsleitungen durchgeführt werden.On the other hand, the anti-rotation device according to the invention also allows the area radially within the bearing surface can be made more free: since this area is no longer needed to form an anti-rotation, the bushing can be better to eg production requirements, especially when manufactured by plastic injection, optimized and / or this area can be optimally adapted to the requirements arising from the reception of the trunnion. In addition, the region lying radially within the bearing surface can now also be used for other components or functions. Thus, a receptacle for a leveling foot can be created in this area and / or supply lines can be carried out.
Der Korpus des erfindungsgemäßen Haushaltsgeräts weist, sofern es sich um ein Haushaltskältegerät handelt, einen Innenbehälter, der eine Begrenzung des Lagerraumes für das Kühlgut bildet, eine Außenverkleidung, die eine äußere Begrenzung des Haushaltskältegerätes bildet, sowie eine zwischen Innenbehälter und Außenverkleidung eingebrachte Isolationsschicht auf. Die Isolationsschicht wird vorzugsweise durch Isolationsschaum, z.B. expandierten Polyurethanschaum, gebildet. Das erfindungsgemäße Haushaltsgerät weist zumindest ein um eine Schwenkachse gegenüber dem Korpus drehbares Türblatt zum wahlweisen Verschließen und Öffnen des Lagerraumes auf. Jedes Türblatt ist zumindest über zwei Lagervorrichtungen an dem Korpus angeschlagen. Dabei kann die Lagervorrichtung am Innenbehälter, an Teilen der Außenverkleidung, wie z.B. Stirnleisten, oder Kombinationen hieraus befestigt sein. Die erfindungsgemäße Lagervorrichtung kann grundsätzlich als oberes oder unteres Türlager verwendet werden.The body of the household appliance according to the invention has, insofar as it is a household refrigeration appliance, an inner container which forms a boundary of the storage space for the refrigerated goods, an outer lining which forms an outer boundary of the household refrigerator, and an insulation layer introduced between the inner container and the outer lining. The insulating layer is preferably provided by insulating foam, e.g. expanded polyurethane foam, formed. The household appliance according to the invention has at least one door leaf rotatable about a pivot axis relative to the body for selectively closing and opening the storage space. Each door leaf is struck at least over two storage devices on the body. In this case, the bearing device on the inner container, on parts of the outer lining, such. End strips, or combinations thereof be attached. The storage device according to the invention can in principle be used as an upper or lower door storage.
Die Lagerbuchse stellt mit ihrer Lagerfläche einen Teil eines Gleitlagers bereit, über welches das Türblatt gegenüber dem Korpus verdreht werden kann. Vorzugsweise wird die Lagerfläche durch eine Außenmantelfläche eines kreiszylindrischen Abschnitts der Lagerbuchse gebildet. Das Türblatt weist als komplementärer Bestandteil des Gleitlagers eine geometrisch an die Lagerfläche angepasste Lagerhülse auf. Vorzugsweise weist die Lagerhülse als Lagerfläche eine Innenmantelfläche einer kreiszylindrischen Bohrung auf. Eine Anpassung des Außendurchmessers des kreiszylindrischen Abschnitts der Lagerbuchse und der kreiszylindrischen Bohrung der Lagerhülse sorgt für eine spielfreie Lagerung des Türblatts. Die Lagerhülse wird vorzugsweise in einer oberen bzw. unteren Türabschlussleiste des Türblattes integriert, entweder als separates Bauteil oder einteilig mit der Türabschlussleiste ausgeformt. Die Lagerhülse wird vorzugsweise durch eine Sacklochbohrung gebildet. Vorzugsweise handelt es sich bei der Lagerhülse um ein Kunststoffbauteil.The bearing bush provides with its bearing surface a part of a plain bearing, over which the door leaf can be rotated relative to the body. Preferably, the bearing surface is formed by an outer circumferential surface of a circular cylindrical portion of the bearing bush. The door leaf has as a complementary component of the sliding bearing on a geometrically adapted to the bearing surface bearing sleeve. Preferably, the bearing sleeve has a bearing surface as an inner circumferential surface of a circular cylindrical bore. An adaptation of the outer diameter of the circular cylindrical portion of the bearing bush and the circular cylindrical bore of the bearing sleeve ensures a play-free mounting of the door leaf. The bearing sleeve is preferably integrated in an upper or lower door closure strip of the door leaf, either as a separate component or integrally formed with the door closure strip. The bearing sleeve is preferably formed by a blind hole. Preferably, the bearing sleeve is a plastic component.
Indem somit eine zylinderförmige Lagerfläche auf der Außenseite der Lagerbuchse geschaffen werden kann, kann die Geometrie des Lagerzapfens praktisch beliebig sein - sie ist nur dadurch beschränkt, dass die Lagerbuchse auf den Lagerzapfen aufgesteckt werden können muss. Insbesondere kann der Lagerzapfen einen Endabschnitt mit rechteckigen, z.B. quadratischen, Querschnitt aufweisen, auf den die Lagerbuchse mit einer geometrisch entsprechend angepassten Aufnahme aufgesteckt wird.By thus creating a cylindrical bearing surface on the outside of the bearing bush, the geometry of the journal can be virtually arbitrary - it is only limited by the fact that the bearing bush must be able to be plugged onto the journal. In particular, the bearing journal with an end portion have rectangular, for example, square, cross-section, on which the bearing bush is fitted with a geometrically correspondingly adapted recording.
Um das Einhängen des Türblattes in die Lagervorrichtung zu erleichtern, kann die Lagerbuche an dem den Türblatt zugewandten Ende der Lagerfläche eine Einführschräge aufweisen. An den kreiszylindrischen Abschnitt kann sich somit ein kegelstumpfförmiger Endabschnitt anschließen.In order to facilitate the hanging of the door leaf in the storage device, the bearing bush may have an insertion bevel at the door leaf end facing the bearing surface. Thus, a frusto-conical end section can follow the circular-cylindrical section.
Bei dem Lagerzapfen und der Lagebuchse handelt es sich um zwei separate Bauteile, die, nachdem die Lagerbuchse auf den Lagerzapfen gesteckt wurde, vorzugsweise zerstörungsfrei wieder voneinander getrennt werden können.The journal and the bushing are two separate components, which after the bushing has been placed on the journal, preferably non-destructive can be separated from each other again.
Die durch die Verdrehsicherung bewirkte drehfeste Verbindung von Lagerbuchse und Lagerzapfen kann durch Formschluss, durch Reibschluss, durch Kraftschluss oder Kombinationen hieraus gebildet werden. Bevorzugt ist eine durch Formschluss gebildete Verdrehsicherung, da sie sich sehr leicht montieren bzw. demontieren lässt.The rotationally fixed connection of the bearing bush and bearing journal caused by the rotation lock can be formed by positive locking, by frictional engagement, by frictional connection or combinations thereof. Preference is given to a rotation formed by positive locking, since it can be very easy to assemble or disassemble.
Die Verdrehsicherung kann optional neben dem Freiheitsgrad der Rotation zwischen Lagerbuchse und Lagerzapfen auch zusätzlich den Freiheitsgrad einer Längsverschiebung von Lagerbuchse und Lagerzapfen, z.B. entlang der Schwenkachse, ein- oder beidseitig behindern. Vorzugsweise soll die Verdrehsicherung jedoch nur den Freiheitsgrad der Rotation behindern; dies ermöglicht eine hierauf optimal gestaltete Verdrehsicherung, während der Freiheitsgrad der Längsverschiebung anderweitig behindert werden kann.In addition to the degree of freedom of rotation between the bearing bush and the bearing journal, the anti-twist device can also optionally provide the degree of freedom of a longitudinal displacement of the bearing bush and the bearing journal, e.g. along the pivot axis, obstruct one or both sides. Preferably, however, the rotation is to hinder only the degree of freedom of rotation; this allows an optimally designed against rotation, while the degree of freedom of the longitudinal displacement can otherwise be hindered.
Bevorzugte Ausführungsformen sind in den Unteransprüchen angegeben.Preferred embodiments are specified in the subclaims.
Der Lagerzapfen ist erfindungsgemäß mittels eines Lagerarms mit dem Korpus verbunden. Dabei kann der Lagerarm derart von dem Korpus abstehen, dass die Schwenkachse entsprechend weit vom Korpus beabstandet ist. Der Lagerarm kann durch ein längliches Bauteil gebildet werden, an dessen erstem Ende der Lagerzapfen sitzt und welches an dessen zweitem Ende mit dem Korpus verbunden wird. Der Lagerarm kann dabei vorzugsweise an dem zweiten Ende eine Haltelasche aufweisen, die in eine korrespondierende Halteöffnung des Korpus eingreift. Alternativ oder zusätzlich kann der Lagerarm über eine oder mehrere Befestigungslöcher verfügen, mittels derer der Lagerarm durch Befestigungsmittel wie Schrauben an dem Korpus dauerhaft befestigt werden kann. Der Korpus weist hierfür entsprechende Befestigungsaufnahmen auf. Ebenfalls alternativ oder zusätzlich kann der Lagerarm weiterhin einen Positionierzapfen aufweisen, mittels dessen die exakte Lage der Lagerarms bezüglich des Korpus festgelegt wird, bevor der Lagerarm, z.B. mittels der Befestigungsmittel, am Korpus befestigt wird; der Korpus weist hierzu eine entsprechende Positionieraufnahme auf.The journal is connected according to the invention by means of a bearing arm with the body. In this case, the bearing arm can protrude from the body in such a way that the pivot axis is spaced correspondingly far from the body. The bearing arm can be formed by an elongated member, sitting at the first end of the bearing pin and which is connected at its second end to the body. The bearing arm may preferably have at the second end a retaining tab which engages in a corresponding retaining opening of the body. Alternatively or additionally, the Have storage arm on one or more mounting holes, by means of which the bearing arm can be permanently attached by fasteners such as screws on the body. The body has appropriate fastening receptacles for this purpose. Also alternatively or additionally, the bearing arm may further comprise a positioning pin, by means of which the exact position of the bearing arm is fixed relative to the body before the bearing arm, for example by means of the fastening means, is secured to the body; For this purpose, the body has a corresponding positioning receptacle.
Erfindungsgemäß sind der Lagerzapfen und der Lagerarm einteilig ausgebildet, vorzugsweise besteht dieses kombinierte Bauteil aus Metall, z.B. ein Stanzbiegeteil oder ein Druckgussteil. Vorzugsweise handelt es sich bei der Lagerbuchse um ein Kunststoffbauteil, z.B. ein Spritzgussteil.According to the invention, the journal and the bearing arm are integrally formed, preferably this combined metal component, e.g. a stamped bent part or a diecasting part. Preferably, the bearing bush is a plastic component, e.g. an injection molded part.
Erfindungsgemäß ist vorgesehen, dass die Verdrehsicherung an einem den Lagerzapfen haltenden Lagerarm und einer an der Lagerbuchse angeordneten radial davon abstehenden Schürze ausgebildet ist, so dass ein sehr einfacher und bezüglich der drehfesten Verbindung sehr effektiver, da direkt wirkender, Aufbau vorliegt. Bezogen auf die Lagerfläche der Lagerbuchse steht die Schürze nur in einer Radialrichtung ab, insbesondere direkt von der Lagerfläche, d.h. es liegt außerdem ein sehr kompakter Aufbau vor. Erfindungsgemäß steht die Schürze radial in Richtung einer Längserstreckung des Lagerarms ab. Weiter vorzugsweise weist der Lagerarm in einer Schnittdarstellung senkrecht zur Schwenkachse eine Symmetrieebene auf, die in diesem Fall zugleich eine Symmetrieebene der Schürze, vorzugsweise der kompletten Lagerbuchse, ist. Ein sehr kompakter und stabiler Aufbau resultiert, wenn die Schürze in einer Schnittdarstellung senkrecht zur Schwenkachse nicht über den Lagerarm hervorsteht. Vorzugsweise ist die Schürze einteilig an der Lagerbuchse angeformt, bildet also ein Teil der Lagerbuchse, so dass ein stabiler Aufbau und eine einfache Fertigung resultiert.According to the invention it is provided that the anti-rotation is formed on a bearing pin holding the bearing arm and arranged on the bearing bush radially projecting apron, so that a very simple and with respect to the rotationally fixed connection is very effective, since there is direct acting structure. Based on the bearing surface of the bearing bush, the skirt is only in a radial direction, in particular directly from the bearing surface, i. There is also a very compact structure. According to the invention, the skirt protrudes radially in the direction of a longitudinal extent of the bearing arm. Further preferably, the bearing arm in a sectional view perpendicular to the pivot axis on a plane of symmetry, which is in this case at the same time a plane of symmetry of the skirt, preferably the complete bearing bush. A very compact and stable construction results when the apron in a sectional view perpendicular to the pivot axis does not protrude beyond the bearing arm. Preferably, the skirt is integrally formed on the bearing bush, so it forms part of the bearing bush, so that a stable structure and a simple production results.
Erfindungsgemäß ist vorgesehen, dass ein von der Schürze abstehender Zapfen in eine Aufnahme des Lagerarms eingreift. Dadurch wird eine sehr einfach herzustellende und dennoch sehr wirksame Verdrehsicherung gewährleistet. Dieser Zapfen ist vorteilhafterweise einteilig mit der Schürze ausgebildet. Der Zapfen kann massiv oder hohl sein, insbesondere mit einer Sacklochbohrung ausgebildet sein. Die Aufnahme des Lagerarms kann durch eine Bohrung, z.B. Durchgangs- oder Sacklochbohrung, oder bei aufgesteckter Lagerbuchse durch neben dem Zapfen liegende Vorsprünge des Lagerarms gebildet werden. Vorzugsweise ist der Zapfen in einer Schnittdarstellung senkrecht zur Schwenkachse innerhalb eines Randbereichs der Schürze angeordnet. Die Verbindungsstelle von Zapfen und Aufnahme kann dadurch vor Verunreinigungen geschützt, da diese durch die Schürze abgedeckt ist, und die Lagervorrichtung leichter gereinigt werden.According to the invention it is provided that a pin protruding from the skirt engages in a receptacle of the bearing arm. This ensures a very easy to produce and yet very effective anti-rotation. This pin is advantageously formed integrally with the skirt. The pin may be solid or hollow, in particular be formed with a blind hole. The inclusion of the bearing arm can through a hole, eg through or blind hole, or at plugged bearing bush are formed by lying next to the pin projections of the bearing arm. Preferably, the pin is arranged in a sectional view perpendicular to the pivot axis within an edge region of the skirt. The joint of pin and receptacle can thereby be protected from contamination, as it is covered by the apron, and the storage device to be cleaned more easily.
Erfindungsgemäß ist vorgesehen, dass ein bezogen auf die Schwenkachse zwischen Zapfen und Aufnahme bestehendes Radialspiel größer als ein bezogen auf die Schwenkachse zwischen Zapfen und Aufnahme bestehendes Tangentialspiel ist, insbesondere dass das Radialspiel durch eine Spielpassung und das Tangentialspiel durch eine Presspassung gebildet ist. Das Radialspiel bezeichnet das Spiel, welches der Zapfen in einer Schnittdarstellung senkrecht zur Schwenkachse entlang einer radialen Verbindungslinie zwischen Zapfenmittelpunkt und Schwenkachse gegenüber der Aufnahme aufweist. Das Tangentialspiel bezeichnet das Spiel, welches der Zapfen in dieser Schnittdarstellung senkrecht zum Radialspiel gegenüber der Aufnahme aufweist. Dies gewährleistet einerseits eine eng tolerierte und eine somit sofort beim Einwirken eines Drehmoments auf die Lagerbuchse greifende Verdrehsicherung. Andererseits kann das größere Radialspiel etwaige Fertigungstoleranzen hinsichtlich der Position des Lagerzapfens ausgleichen. Insbesondere wenn der Lagerzapfen einstückig mit dem Lagerarm als Stanzbiegeteil ausgeführt wird, kann die Position des Lagerzapfens in Radialrichtung bezogen auf die Schwenkachse unter Umständen leicht von Bauteil zu Bauteil variieren, was durch das Radialspiel ausgeglichen werden kann, ohne dass es zu Radialbelastungen auf die Verdrehsicherung kommt. Die präzise Wirkung der Verdrehsicherung wird durch das größere Radialspiel jedoch nicht beeinflusst. Sofern das Tangentialspiel als Presspassung ausgeführt wird, liegt darüber hinaus eine verliersichere Einheit von Lagerbuchse und Lagerzapfen vor, wodurch die Montage vereinfacht wird.According to the invention, it is provided that a relative to the pivot axis between pins and recording existing radial clearance is greater than a relation to the pivot axis between pins and recording existing tangential, in particular that the radial clearance is formed by a clearance and the Tangentialspiel by a press fit. The radial clearance refers to the game, which has the pin in a sectional view perpendicular to the pivot axis along a radial connecting line between the journal center and pivot axis with respect to the recording. The tangential game refers to the game, which has the pin in this sectional view perpendicular to the radial clearance relative to the recording. On the one hand, this ensures a tightly-tolerated and thus an anti-twist device which engages the bearing bush immediately upon the application of a torque. On the other hand, the larger radial clearance compensate for any manufacturing tolerances with respect to the position of the journal. In particular, when the bearing pin is made integral with the bearing arm as a stamped and bent part, the position of the journal in the radial direction relative to the pivot axis may vary slightly from component to component, which can be compensated by the radial clearance, without causing radial loads on the rotation , The precise effect of the anti-rotation device is not affected by the greater radial play. If the tangential play is carried out as a press fit, there is also a captive unit of bearing bush and bearing pin, whereby the assembly is simplified.
Das unterschiedlich große Radial- und Tangentialspiel kann gemäß einer Ausführungsform dadurch erreicht werden, dass die Aufnahme einen Kreisquerschnitt und der Zapfen einen im Wesentlichen elliptischen oder gotischen Querschnitt aufweist. Dabei wird ausgenutzt, dass eine Aufnahme mit Kreisquerschnitt einfach und dennoch präzise, z.B. durch Stanzen ohne Nachbearbeitung, des Lagerarms hergestellt werden kann. Die komplexere Form des Zapfens hingegen kann leichter an der Lagerbuchse realisiert werden, z.B. durch Spritzgießen. Der Querschnitt des Zapfens wird durch eine Schnittebene senkrecht zur Längserstreckung des länglichen Zapfens gebildet. Dieser Querschnitt ist vorzugsweise bezüglich zweier Symmetrieachsen jeweils spiegelsymmetrisch und weist eine im Wesentlichen tangential zur Schwenkachse ausgerichtete größere erste Erstreckung als eine im Wesentlichen radial zur Schwenkachse ausgerichtete zweite Erstreckung auf. Dies wird durch entsprechende Ausrichtung des elliptischen oder gotischen Querschnitts erreicht. Der gotische Querschnitt basiert auf einem elliptischen Querschnitt, weist jedoch weist jedoch Knickpunkte in den beiden Hauptscheiteln auf. Alternativ kann die Aufnahme durch ein Langloch gebildet werden und der Zapfen einen Kreisquerschnitt aufweisen. Dies ermöglicht einen sehr großen Wert des Radialspieles und zugleich kann der Zapfen durch einen unvermindert großen Kreisquerschnitt eine hohe Festigkeit aufweisen. Die Längserstreckung des Langloches erstreckt sich bei einer Schnittdarstellung senkrecht zur Längserstreckung des Zapfens im Wesentlichen radial hinsichtlich der Schwenkachse.The different sized radial and tangential play can be achieved according to an embodiment in that the receptacle has a circular cross-section and the pin has a substantially elliptical or Gothic cross-section. It is exploited that a recording with circular cross-section can be made simple yet precise, eg by punching without post-processing of the bearing arm. The more complex shape of the pin, however, can be easily realized on the bearing bush be, for example by injection molding. The cross section of the pin is formed by a sectional plane perpendicular to the longitudinal extent of the elongated pin. This cross-section is preferably mirror-symmetrical in each case with respect to two axes of symmetry and has a larger first extent oriented substantially tangentially to the pivot axis as a second extent oriented essentially radially to the pivot axis. This is achieved by appropriate alignment of the elliptical or Gothic cross-section. The gothic cross-section is based on an elliptical cross-section, however, has kink points in the two main vertices. Alternatively, the receptacle can be formed by a slot and the pin have a circular cross-section. This allows a very large value of the radial clearance and at the same time, the pin can have a high strength by an undiminished large circular cross-section. The longitudinal extension of the elongated hole extends in a sectional view perpendicular to the longitudinal extension of the pin substantially radially with respect to the pivot axis.
Gemäß einer Ausführungsform ist vorgesehen, dass die Schürze an einem dem Türblatt abgewandten Ende der Lagerbuchse angeordnet ist, so dass die Lagerbuchse größtenteils, insbesondere die Lagerfläche sowie eine optionale Einführschräge, komplett in einer entsprechenden Lagerhülse des Türblatts aufgenommen werden kann. Dies führt zu einem kompakten Aufbau.According to one embodiment, it is provided that the skirt is arranged on a side facing away from the door leaf end of the bearing bush, so that the bearing bush largely, in particular the bearing surface and an optional insertion, can be completely accommodated in a corresponding bearing sleeve of the door leaf. This leads to a compact construction.
Gemäß einer Ausführungsform ist vorgesehen, dass eine dem Türblatt zugewandte Oberfläche der Schürze bezüglich einer im Wesentlichen kreisringförmigen Stützfläche der Lagerbuchse bezogen auf die Schwenkachse axial freigestellt ist. Die Führung des Türblatts erfolgt somit ausschließlich über die Lagerfläche der Lagerbuchse, die Stützfläche der Lagerbuchse sowie eine Lagerfläche innerhalb des Türblatts. Indem die Oberfläche der Schürze axial freigestellt wird, also bezogen auf die Stützfläche axial zurückgenommen wurde, hat diese keinen Kontakt zum Türblatt, so dass die beim Verschwenken des Türblatts entstehende Reibung minimiert wird.According to one embodiment, it is provided that a surface of the apron facing the door leaf is axially free relative to a substantially annular support surface of the bearing bush with respect to the pivot axis. The guide of the door leaf is thus exclusively on the bearing surface of the bearing bush, the support surface of the bearing bush and a bearing surface within the door leaf. By the surface of the skirt is released axially, that was axially withdrawn with respect to the support surface, this has no contact with the door leaf, so that the resulting during pivoting of the door panel friction is minimized.
Die Schürze wird somit nicht direkt mit der Gewichtskraft des Türblatts beaufschlagt. Andererseits kann die Schürze jedoch dazu dienen, mittelbar, z.B. über die Stützfläche, aufgenommene Gewichtskräfte von der Lagerbuchse auf andere Bauteile abzuleiten. So kann gemäß einer Ausführungsform vorgesehen sein, dass die Lagerbuchse sich über eine sich bis unter die Schürze erstreckende Abstützfläche auf einem Lagerarm abstützt. Die insgesamt zur Verfügung stehende Fläche zum Abstützen der Lagerbuchse kann hierdurch erhöht werden, wodurch die Stabilität der Lagervorrichtung verbessert wird. Vorzugsweise stützt sich die Lagerbuchse auf einem ebenen und senkrecht zur Schwenkachse stehenden Flächenabschnitt einer Oberfläche des Lagerarms ab. Gemäß einer Ausführungsform ist vorgesehen, dass die Schürze in einer Schnittdarstellung senkrecht zur Schwenkachse nicht über den Lagerarm hervorsteht. Es liegt somit ein kompakter Aufbau vor und die Schürze kann besser vor Beschädigungen geschützt werden.The apron is thus not directly applied to the weight of the door leaf. On the other hand, however, the apron can serve indirectly, for example via the support surface, to dissipate absorbed weight forces from the bearing bush to other components. Thus, according to one embodiment, it can be provided that the bearing bush extends over an up to under the skirt extending support surface supported on a bearing arm. The total available area for supporting the bushing can be increased thereby, whereby the stability of the bearing device is improved. Preferably, the bearing bush is supported on a flat and perpendicular to the pivot axis surface portion of a surface of the bearing arm. According to one embodiment, it is provided that the skirt in a sectional view perpendicular to the pivot axis does not project beyond the bearing arm. There is thus a compact structure and the apron can be better protected against damage.
Gemäß einer Ausführungsform ist vorgesehen, dass der Lagerzapfen einen rechteckigen Querschnitt aufweist und formschlüssig in einer Öffnung der Lagerbuchse sitzt. Möglich ist, dass die Öffnung der Lagerbuchse korrespondierend zur rechteckigen Form des Lagerzapfens gestaltet ist, insbesondere in einer Schnittdarstellung senkrecht zur Schwenkachse den Lagerzapfen umfänglich komplett umschließt. Denkbar ist auch, dass der Lagerzapfen nur an zwei sich diagonal gegenüberliegenden, mehreren oder allen vier Ecken und/oder zwei oder mehreren seiner Seitenflanken durch entsprechende Bereiche der Öffnung gehalten wird, wodurch der Bereich innerhalb der Lagerfläche größtmöglich für andere Bauteile genutzt werden kann. Möglich ist insbesondere, dass die Öffnung in einer Schnittdarstellung senkrecht zur Schwenkachse den Lagerzapfen über eine Spielpassung aufnimmt. Aufgrund der erfindungsgemäßen Verdrehsicherung ist nämlich eine eng tolerierte, insbesondere durch Presspassung erreichte, Führung des Lagerzapfens in der Öffnung der Lagerbuchse nicht notwendig bzw. aufgrund einer möglichen Überbestimmung zu vermeiden.According to one embodiment, it is provided that the bearing journal has a rectangular cross-section and is seated in a form-fitting manner in an opening of the bearing bush. It is possible that the opening of the bearing bush is designed corresponding to the rectangular shape of the journal, in particular in a sectional view perpendicular to the pivot axis completely surrounds the bearing journal. It is also conceivable that the bearing journal is held only at two diagonally opposite, several or all four corners and / or two or more of its side edges by corresponding areas of the opening, whereby the area within the storage area can be used as possible for other components. It is possible in particular that the opening in a sectional view perpendicular to the pivot axis receives the bearing pin via a clearance fit. Because of the anti-rotation device according to the invention namely a narrow tolerances, especially achieved by press-fitting, guiding the trunnion in the opening of the bearing bush is not necessary or to avoid due to a possible overdetermination.
Um den Bereich innerhalb der Lagerfläche bestmöglich für andere Bauteile ausnutzen zu können, ist gemäß einer Ausführungsform vorgesehen, dass die Öffnung bezüglich der Schwenkachse außermittig angeordnet ist. Vorzugsweise wird dabei, bezogen auf die Schwenkachse, die Öffnung radial gegenüberliegend der Schürze angeordnet, so dass sich die Lagerbuchse über eine größtmögliche Auflagefläche auf dem Lagerarm abstützen kann, indem die Lagerbuchse weit in Richtung der Längserstreckung des Lagerarms bzw. in Richtung des Korpus positioniert wird.In order to make the best possible use of the area within the storage area for other components, it is provided according to an embodiment that the opening is arranged eccentrically with respect to the pivot axis. Preferably, in relation to the pivot axis, the opening is arranged radially opposite the skirt, so that the bearing bush can be supported on the bearing arm over the largest possible bearing surface by positioning the bearing bush far in the direction of the longitudinal extent of the bearing arm or in the direction of the body ,
Aufgrund der radial außerhalb der Lagerfläche liegenden Verdrehsicherung kann gemäß einer Ausführungsform vorgesehen sein, dass die Lagerbuchse eine Bohrung zur Aufnahme eines Schaftes eines Stellfußes aufweist. Vorzugsweise liegt diese Bohrung bezüglich der Schwenkachse außermittig, weiter vorzugsweise liegt in diesem Fall auch die Öffnung zur Aufnahme des Lagerzapfens außermittig, so dass der Bereich innerhalb der Lagerfläche bestmöglich ausgenutzt werden kann. Vorzugsweise verläuft eine Rotationssachse der Bohrung parallel zu einer Rotationssachse der Öffnung, weiter vorzugsweise liegen beiden Achsen jedoch nicht aufeinander. Die Bohrung weist vorzugsweise zwar einen konstanten Querschnitt auf, kann sich jedoch mit der Öffnung derart überschneiden, dass Bohrung und Öffnung miteinander verbunden sind.Due to the anti-rotation locking lying radially outside the bearing surface can be provided according to an embodiment that the bearing bush has a bore for receiving a shank of a leveling foot. Preferably, this bore is off-center with respect to the pivot axis, further preferably in this case, the opening for receiving the journal is off-center, so that the area can be utilized in the best possible way within the storage area. Preferably, a rotational axis of the bore is parallel to a rotational axis of the opening, more preferably, however, both axes are not adjacent to each other. Although the bore preferably has a constant cross-section, but may intersect with the opening such that bore and opening are interconnected.
Gemäß einer Ausführungsform ist vorgesehen, dass ein Lagerarm zumindest eine Stellfußaufnahme zur Aufnahme eines Schaftes eines Stellfußes aufweist, vorzugsweise dass der Lagerarm zumindest zwei Stellfußaufnahmen zur Aufnahme eines Schaftes eines Stellfußes aufweist und eine der Stellfußaufnahmen mit der Bohrung der Lagerbuchse fluchtet. Die Stellfußaufnahme(n) des Lagerarms ist bzw. sind Bohrungen, vorzugsweise mit einem Gewinde versehen, um den Stellfuß einschrauben zu können. Für den Fall, dass der Lagerarm zwei entsprechende Stellfußaufnahmen aufweist, kann die Position des Stellfußes gewechselt werden. Beispielsweise kann bei einem Haushaltsgerät, dessen Türblatt nur ein verhältnismäßig geringes Eigengeweicht aufweist, eine Position des Stellfußes näher zum Korpus gewählt werden, so dass der Stellfuß unter Umständen komplett unter dem Korpus liegt; der Bereich des Bodens unter dem Türblatt auf dem das Haushaltsgerät steht kann somit einfacher gereinigt werden. Falls jedoch das Türblatt ein verhältnismäßig großes Eigengewicht aufweist, kann als Position des Stellfußes jene Stellfußaufnahme im Lagerarm gewählt werden, welche mit der Bohrung in der Lagerbuchse fluchtet. Das auf den Lagerarm wirkende Biegemoment kann in diesem Fall reduziert bzw. nahezu komplett eliminiert werden.According to one embodiment, it is provided that a bearing arm has at least one adjustable foot receptacle for receiving a shank of an adjustable foot, preferably that the bearing arm has at least two Stellfußaufnahmen for receiving a shank of a adjustable foot and one of Stellfußaufnahmen aligned with the bore of the bearing bush. The adjustable foot receptacle (s) of the bearing arm is or are bores, preferably provided with a thread, in order to be able to screw in the adjustable foot. In the event that the bearing arm has two corresponding Stellfußaufnahmen, the position of the adjustable foot can be changed. For example, in a household appliance whose door leaf has only a relatively small amount of inherent tissue, a position of the adjustable foot can be selected closer to the body, so that under certain circumstances the leveling foot lies completely underneath the carcass; the area of the floor under the door leaf on which the appliance is standing can thus be cleaned more easily. However, if the door leaf has a relatively large weight, can be selected as the position of the adjustable foot Stellfußaufnahme in the bearing arm, which is aligned with the bore in the bearing bush. The bending moment acting on the bearing arm can in this case be reduced or almost completely eliminated.
Gemäß einer Ausführungsform ist vorgesehen, dass der Lagerzapfen im Wesentlichen senkrecht von einem Lagerarm absteht. Erfindungsgemäß ist vorgesehen, dass der Lagerzapfen einstückig an dem Lagerarm ausgebildet. Der Lagerzapfen weist vorzugsweise einen Endabschnitt mit konstantem Querschnitt auf, der über einen Bogenabschnitt mit einer ebenen Oberfläche des Lagerarms verbunden ist. Eine einfache Herstellung resultiert, wenn der Lagerarm inklusive Lagerzapfen als Stanzbiegeteil aus einem Blech konstanter Dicke hergestellt wird, so dass eine Dicke des Lagerarms einer Breite des Lagerzapfens sowie entspricht.According to one embodiment, it is provided that the bearing pin protrudes substantially perpendicularly from a bearing arm. According to the invention it is provided that the bearing pin formed integrally on the bearing arm. The trunnion preferably has an end portion of constant cross-section, which is connected via an arc portion with a flat surface of the bearing arm. A simple production results when the bearing arm including bearing pin as a stamped and bent part a sheet of constant thickness is produced, so that a thickness of the bearing arm corresponds to a width of the journal and.
