Description

Die vorliegende Erfindung betrifft einen Hebemechanismus mit einer Ablage zum Einbau in einem Schubkasten oder einem Korpus eines Möbels oder Haushaltsgerätes gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft des Weiteren ein Möbel oder Haushaltsgerät und einen Schubkasten.The present invention relates to a lifting mechanism with a shelf for installation in a drawer or a body of a piece of furniture or household appliance according to the preamble of claim 1. The invention also relates to a piece of furniture or household appliance and a drawer.

Solche Hebemechanismen dienen dazu, Ablagen mithilfe einer Betätigungsmechanik aus einer abgesenkten unteren in eine angehobene obere Position zu verfahren, um die auf oder in der Ablage abgelegten Gegenstände herausnehmen oder auflegen zu können.Such lifting mechanisms are used to move shelves with the aid of an actuating mechanism from a lowered lower position to a raised upper position in order to be able to remove or place the objects stored on or in the shelf.

Ein solcher gattungsgemäßer Hebemechanismus ist beispielsweise aus der DE 10 2016 120 533 A1 bekannt. Der dort beschriebene Hebemechanismus weist ein Paar von Scherenmechaniken auf, mit jeweiligen ersten und zweiten Scherenhebeln, die über einen Schwenkhebel mit daran angeordnetem Griff bedienbar ist.Such a generic lifting mechanism is for example from DE 10 2016 120 533 A1 known. The lifting mechanism described there has a pair of scissor mechanisms, with respective first and second scissor levers, which can be operated via a pivot lever with a handle arranged thereon.

Eine andere Ausführungsform für einen Hebemechanismus ist in der EP2890271 B1 und der WO 2010/124947 A2 beschrieben. Der dort beschriebene Hebemechanismus weist ein Paar von Schiebe-Schwenkmechaniken mit wenigstens zwei an einer der Seitenwände des Korpus mit einem ersten Ende parallel zur Ebene der Seitenwände drehbar festgelegten und parallel zueinander beabstandet angeordneten Schwenkarmen auf, wobei an jeweiligen zweiten Enden der Schwenkarme eine Führungsschiene derart parallel zur Ebene der Seitenwände schwenkbar festgelegt sind, dass die Führungsschiene aus einer unteren Position innerhalb des Korpus in eine angehobene, obere Position zumindest teilweise außerhalb des Korpus verschwenkbar ist, und zumindest eine in der Führungsschiene linear verschiebbare Laufschiene, an der die Ablage befestigt ist.Another embodiment for a lifting mechanism is shown in FIG EP2890271 B1 and the WO 2010/124947 A2 described. The lifting mechanism described there has a pair of sliding / pivoting mechanisms with at least two pivot arms fixed to one of the side walls of the body with a first end so as to be rotatable parallel to the plane of the side walls and spaced parallel to one another, with a guide rail in such a parallel manner at the respective second ends of the pivot arms to the plane of the side walls are fixed that the guide rail can be pivoted from a lower position inside the body to a raised, upper position at least partially outside the body, and at least one running rail linearly displaceable in the guide rail to which the shelf is attached.

Zur Stabilisierung des Hebemechanismus sind die zweiten Enden der beidseits der Ablage angeordneten Scherenhebel bzw. die zweiten Enden der beidseits der Ablage angeordneten Schwenkarme über eine Querstange miteinander gekoppelt.To stabilize the lifting mechanism, the second ends of the scissor levers arranged on both sides of the shelf or the second ends of the pivot arms arranged on both sides of the shelf are coupled to one another via a transverse rod.

Nachteilig an den vorgenannten Hebemechanismus ist, dass ein solcher Hebemechanismus jeweils nur für Ablagen vorbestimmter Breite einsetzbar ist.The disadvantage of the aforementioned lifting mechanism is that such a lifting mechanism can only be used for shelves of a predetermined width.

Aufgabe der vorliegenden Erfindung ist es, einen Hebemechanismus sowie ein Möbel oder Haushaltsgerät bzw. einen Schubkasten mit einem solchen Hebemechanismus dahingehend weiterzuentwickeln, dass der Hebemechanismus variabel für unterschiedliche Ablagen einsetzbar ist.The object of the present invention is to further develop a lifting mechanism and a piece of furniture or household appliance or a drawer with such a lifting mechanism in such a way that the lifting mechanism can be used variably for different shelves.

Diese Aufgabe wird durch einen Hebemechanismus mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a lifting mechanism with the features of claim 1.

Die Aufgabe wird des Weiteren durch ein Möbel oder Haushaltsgerät mit den Merkmalen des Anspruchs 8 bzw. 11 sowie durch einen Schubkasten mit den Merkmalen des Anspruchs 15 gelöst.The object is also achieved by a piece of furniture or household appliance with the features of claim 8 or 11 and by a drawer with the features of claim 15.

Der erfindungsgemäße Hebemechanismus weist ein Paar von Mechaniken zum Anheben und Absenken der Ablage, die an beiden Seiten der Ablage angeordnet sind, auf. Die beiden Mechaniken sind über eine Synchronisationsstange miteinander gekoppelt, die in ihrer Länge variabel einstellbar ist.The lifting mechanism according to the invention has a pair of mechanisms for raising and lowering the tray, which are arranged on both sides of the tray. The two mechanisms are coupled to one another via a synchronization rod, which can be variably adjusted in length.

Ein erfindungsgemäßer Hebemechanismus weist eine Scherenmechanik mit zwei Paaren von gekreuzten und drehbar miteinander verbundenen Scherenhebeln zum Anheben und Absenken der Ablage auf. Ein jeweiliger erster Scherenhebel ist dabei am ersten Ende ortsfest und drehbar und ein jeweiliger zweiter Scherenhebel an einem ersten Ende drehbar und verschiebbar an der Ablage angeordnet.A lifting mechanism according to the invention has a scissor mechanism with two pairs of crossed and rotatably connected scissor levers for raising and lowering the shelf. A respective first scissor lever is fixed and rotatable at the first end and a respective second scissor lever is arranged rotatably and displaceably on the shelf at a first end.

Ein zweites Ende des ersten Scherenhebels ist drehbar und verschiebbar und ein zweites Ende des zweiten Scherenhebels ortsfest und drehbar an dem Schubkasten oder oder an einer Auszugsführung oder dem Korpus des Möbels oder Haushaltsgerätes angeordnet. Die beiden zweiten Enden der ersten Scherenhebel sind dabei über eine Synchronisationsstange miteinander gekoppelt. Die Synchronisationsstange ist dabei in ihrer Länge variabel einstellbar.A second end of the first scissor lever is rotatable and displaceable and a second end of the second scissor lever is fixed and rotatable on the drawer or on a pull-out guide or on the body of the furniture or household appliance. The two second ends of the first scissor lever are coupled to one another via a synchronization rod. The length of the synchronization rod is variably adjustable.

Dadurch ist ein Hebemechanismus geschaffen, der mit Ablagen unterschiedlicher Breiten gekoppelt werden kann, was die Lagerhaltung solcher Hebemechanismen gegenüber einer Lagerhaltung von Hebemechanismen mit festgelegten unterschiedlichen Breiten reduziert. Beispielsweise existieren bei Geschirrspülern Einbaubreiten von 45 und 60 cm, wobei die Ablagen dementsprechend breit ausgeführt sind.This creates a lifting mechanism which can be coupled to shelves of different widths, which reduces the need to keep such lifting mechanisms in stock compared to keeping lifting mechanisms in stock with fixed different widths. For example, exist at Dishwashers installation widths of 45 and 60 cm, with the shelves being designed accordingly wide.

Vorteilhafte Ausführungsvarianten dieser Erfindung sind Gegenstand der Unteransprüche.Advantageous variant embodiments of this invention are the subject of the subclaims.

Gemäß einer vorteilhaften Ausführungsvariante der Erfindung ist die Synchronisationsstange als Teleskopstange ausgebildet.According to an advantageous embodiment of the invention, the synchronization rod is designed as a telescopic rod.

Solche Teleskopstangen sind einfach und kostengünstig herstellbar und in einfacher Weise an den zweiten Enden der ersten Scherenhebel bzw. der Schwenkarme anbringbar.Such telescopic rods can be produced easily and inexpensively and can be attached in a simple manner to the second ends of the first scissor lever or the pivot arms.

Besonders bevorzugt weist die Synchronisationsstange eine erste Stange mit einer Vielzahl von Rastelementaufnahmen und eine zweite Stange mit wenigstens einem vorstehenden Rastelement auf. Die Rastelementaufnahmen sind dabei bevorzugt als Aufnahmelöcher ausgebildet, die hintereinander angeordnet eine Lochleiste bilden.The synchronization rod particularly preferably has a first rod with a plurality of latching element receptacles and a second rod with at least one protruding latching element. The latching element receptacles are preferably designed as receiving holes which, arranged one behind the other, form a perforated strip.

Das wenigstens eine Rastelement ist dabei bevorzugt als federnd in die zweite Stange eindrückbarer Bolzen ausgebildet.The at least one latching element is preferably designed as a resiliently pushable bolt into the second rod.

Denkbar sind auch in anderer Weise gestaltete Rastelemente und entsprechende Rastelementaufnahmen wie beispielsweise Rastelementaufnahmen in Gestaltung einer Verzahnung und eines entsprechenden Zahns an der zweiten Stange.Also conceivable are latching elements configured in a different manner and corresponding latching element receptacles such as, for example, latching element receptacles in the form of a toothing and a corresponding tooth on the second rod.

Denkbar sind auch über ein Schraubgewinde miteinander gekoppelte Stangen.Rods coupled to one another via a screw thread are also conceivable.

Gemäß einer weiteren Ausführungsvariante des zweiten erfindungsgemäßen Hebemechanismus ist an einem freien, von einem Benutzer verschwenkbaren Ende zumindest eines mit einem Paar der Scherenhebel gekoppelten Schwenkhebels ein Griff befestigt.According to a further embodiment variant of the second lifting mechanism according to the invention, a handle is attached to a free end which can be pivoted by a user of at least one pivot lever coupled to a pair of the scissor levers.

Der Griff ist dabei gemäß einer Ausführungsvariante in Längsrichtung teleskopierbar ausgebildet zwischen beiden Schwenkhebeln auf gegenüberliegenden Seiten der Ablage, die Schwenkhebel miteinander verbindend, angeordnet.According to an embodiment variant, the handle is designed to be telescopic in the longitudinal direction between the two pivot levers on opposite sides of the shelf, connecting the pivot levers to one another.

Denkbar ist auch, nur an einer der Scherenmechaniken einen solchen Schwenkhebel anzuordnen, so dass die Scherenmechanik über einen an diesem einen Schwenkhebel angeordneten Griff betätigbar ist.It is also conceivable to arrange such a pivot lever on only one of the scissor mechanisms, so that the scissors mechanism can be actuated via a handle arranged on this one pivot lever.

Gemäß einer weiteren vorteilhaften Ausführungsvariante des zweiten erfindungsgemäßen Hebemechanismus ist an den Enden der Synchronisationsstange jeweils ein Zahnrad angeordnet, das in eine in dem Schubkasten oder dem Korpus des Möbels oder Haushaltsgerätes fixierte Zahnstange eingreift.According to a further advantageous embodiment of the second lifting mechanism according to the invention, a gear is arranged at each end of the synchronization rod, which engages in a rack fixed in the drawer or the body of the furniture or household appliance.

Dadurch wird die synchrone Verschiebung der zweiten Enden des ersten Scherenhebels während der Anhebe- oder Absenkbewegung nochmals verbessert.This further improves the synchronous displacement of the second ends of the first scissor lever during the raising or lowering movement.

Das Möbel oder Haushaltsgerät zeichnet sich durch einen Hebemechanismus, wie oben beschrieben, aus. Der Hebemechanismus mit der Ablage kann dabei in einem Möbelkorpus selbst befestigt sein.The furniture or household appliance is characterized by a lifting mechanism, as described above. The lifting mechanism with the shelf can be fastened in a furniture body itself.

Denkbar ist es auch, den Hebemechanismus in einem aus dem Korpus des Möbels oder Haushaltsgerätes ausziehbaren Schubkasten oder an einer Auszugsführung festzulegen.It is also conceivable to fix the lifting mechanism in a drawer that can be pulled out of the body of the furniture or household appliance or on a pull-out guide.

Bei einem alternativen Möbel oder Haushaltsgerät mit einem Korpus und einem an dem Korpus befestigten Hebemechanismus mit einer Ablage, wobei die Ablage über den Hebemechanismus anhebbar und absenkbar ist und wobei jeweils ein Hebemechanismus an einer Seite der Ablage angeordnet ist, weist der Hebemechanismus ein Paar von Schiebe-Schwenkmechaniken mit wenigstens zwei an einer der Seitenwände des Korpus mit einem ersten Ende parallel zur Ebene der Seitenwände drehbar festgelegten und parallel zueinander beabstandet angeordneten Schwenkarmen auf, wobei an jeweiligen zweiten Enden der Schwenkarme eine Führungsschiene derart parallel zur Ebene der Seitenwände schwenkbar festgelegt sind, dass die Führungsschiene aus einer unteren Position innerhalb des Korpus in eine angehobene, obere Position zumindest teilweise außerhalb des Korpus verschwenkbar ist, zumindest eine in der Führungsschiene linear verschiebbare Laufschiene, an der die Ablage befestigt ist. Die beiden zweiten Enden der beidseits der Ablage angeordneten Schwenkarme sind dabei über eine Synchronisationsstange miteinander gekoppelt, die in ihrer Länge variabel einstellbar ist.In an alternative furniture or household appliance with a body and a lifting mechanism attached to the body with a shelf, the shelf can be raised and lowered via the lifting mechanism and with a lifting mechanism being arranged on one side of the shelf, the lifting mechanism has a pair of slides -Swivel mechanisms with at least two swivel arms fixed parallel to the plane of the side walls with a first end rotatably fixed parallel to the plane of the side walls and arranged parallel to and spaced apart swivel arms on one of the side walls of the body, wherein at respective second ends of the swivel arms a guide rail are fixed so that they can be swiveled parallel to the plane of the side walls that the guide rail is at least partially pivotable from a lower position inside the body to a raised, upper position outside the body, at least one running rail which is linearly displaceable in the guide rail and to which the shelf is attached. The two second ends of the swivel arms arranged on both sides of the shelf are coupled to one another via a synchronization rod, the length of which is variably adjustable.

Der erfindungsgemäße Schubkasten zeichnet sich durch wenigstens einen in einem Aufnahmeraum, insbesondere auf einem Boden des Schubkastens angeordneten Hebemechanismus aus, der wie oben beschrieben ausgebildet ist.The drawer according to the invention is characterized by at least one lifting mechanism which is arranged in a receiving space, in particular on a floor of the drawer and is designed as described above.
