Description

State of the art

In the case of furniture and household appliances with a movably mounted furniture part, such as doors or flaps, different arrangements are known for movably attaching the furniture part to a body of the furniture or household appliance. The furniture part is movable relative to the body when the furniture or household appliance is in use, for example about a horizontally or vertically oriented pivot axis with the hinge arrangement, in order to be able to access an interior of the body and to separate the interior from the outside when the furniture part is closed on the body . The furniture part can regularly be moved manually and/or powered.

In furniture and household appliances such as cupboards or refrigerators or freezers, compact and mechanically stable hinge arrangements are tailored to the specific use on the furniture or household appliance. A proven hinge arrangement designed as a standard product can be used in a wide range of applications. The hinge arrangement is usually connected to the body and the furniture part. In the case of mass-produced products, such as refrigerators and freezers, it is desirable to design the furniture or household appliance on the one hand and the hinge arrangement on the other hand to be appropriately coordinated or prepared, which makes standardization possible. Tried-and-tested hinge arrangements can therefore be used universally for a large number of different furniture and household appliances, which is economically advantageous when assembling such furniture and household appliances.

The disadvantage, particularly when used on a refrigerator or freezer, is that hinge arrangements must be adapted to fixed attachment points on the refrigerator or freezer or on its movable furniture part.

Task and advantages of the invention

The object of the present invention is to improve a hinge arrangement mentioned at the outset and/or an associated piece of furniture or household appliance from an economic and technical perspective. In particular, it is the object of the present invention to further develop the hinge arrangement and/or the associated furniture or household appliance with regard to a routine when assembling the hinge arrangement and/or increased ease of use of the furniture or household appliance for a user.

This task is solved by the independent claims. The dependent claims are directed to expedient and advantageous developments of the invention.

The invention is based on a drive device for moving a furniture part, the furniture part being movably articulated on a furniture body via a hinge, the drive device being connectable to the hinge at a first end portion of the drive device, the drive device being connected to a second end portion of the drive device Furniture part can be fixed, the first and second end sections being opposite and spaced apart from each other, wherein in the arranged state of the drive device on the furniture and the hinge on the furniture, the drive device is movably coupled to a hinge arm of the hinge by means of a drive element of the drive device, so that through a movement of the drive element, the hinge arm and thus the furniture part is movable, the drive element being pivotally connected to a first end of the drive element with a linearly movable thrust element of the drive device, wherein in the arranged state of the drive device on the hinge, the drive element is pivotally movable to a second end of the drive element can be connected to the hinge arm of the hinge. This provides a drive device which can be used comparatively flexibly.

For example, the furniture comprises a furniture body and a furniture part, wherein the furniture part is designed to be movable in relation to the furniture body and can be arranged on the furniture body. For example, the furniture is available as a refrigerator, as a freezer and/or as a fridge-freezer combination. For example, the furniture part is designed as a refrigerator door, as a freezer door and/or as a door of a refrigerator-freezer combination.

For example, the hinge is designed as a refrigerator hinge, as a freezer hinge and/or as a refrigerator-freezer combination hinge. For example, there are fastening elements on the furniture body and/or the furniture part, on which the hinge can be arranged. It is conceivable that fastening elements are present on the furniture part and/or on the furniture body in such a way that the furniture part in the form of a door can be fixed to the furniture body both as a left-hand stop and as a right-hand stop. For example, the furniture part has fastening elements on a first side and on a second side for fastening the hinge, the fastening elements being opposite and spaced apart from the first side to the fastening elements on the second side.

For example, the hinge comprises a first hinge arm and a second hinge arm, wherein the first and second hinge arms are articulated to one another via a third and a fourth hinge arm. For example, the hinge includes a fifth hinge arm, which is connected in an articulated manner to the second hinge arm. For example, the first hinge arm is designed to be arranged on a piece of furniture. For example, the fifth hinge arm is designed to be arranged on a furniture body.

For example, the drive device has a base body. For example, the base body is cuboid, with four outer sides and two end faces, the end faces being opposite one another and spaced apart from one another. For example, the outer sides extend along a longitudinal axis of the base body. For example, the end faces are spaced apart from one another over a longitudinal extent of the base body along the longitudinal axis of the base body. It is conceivable that the base body is present as a hollow body and an end face of the base body is designed to be open.

It is conceivable that the base body is present in the form of a housing. For example, the housing of the drive device is cuboid. For example, the housing is in the form of a hollow body. It is conceivable that the housing, in particular the hollow body, is designed to be open on one side. For example, the drive element or the thrust element extends through the open side of the housing.

For example, the thrust element is movably mounted in the housing. It is conceivable that a linear drive is formed in the housing of the drive device or on the housing of the drive device, which is coupled to the thrust element and drives a linear movement of the thrust element. It is also conceivable that the thrust element is part of the linear drive.

For example, the drive element is designed in the form of an angle element. It is conceivable that the drive element is arcuate and/or curved. It is conceivable that the drive element is present as a metal part. It is also conceivable that the drive element is present as a stamped component and is punched out of a sheet metal. For example, the first and second ends of the drive element are opposite and spaced apart from one another.

For example, the drive element is connected to the thrust element in a pivotable manner, for example in a rotary manner, via a pivot bearing.

It is further proposed that the drive device has two drive elements, the drive elements being spaced apart from one another when viewed in the width direction of the drive device. This improves power transmission from the drive device to the hinge.

For example, the drive device comprises two drive elements, for example exactly two drive elements. For example, the multiple drive elements are designed identically. For example, each drive element is connected to the thrust element at a first end of the respective drive element. For example, the two or more drive elements are present at a distance from one another. For example, the drive element extends from its first end to its second end along its longitudinal axis. For example, the two or more drive elements are spaced apart from one another in a direction transverse to their longitudinal axes, for example in a direction perpendicular to their longitudinal axes.

It is also proposed that the drive device has a positioning element at the first end section, wherein the positioning element is designed to cooperate with a positioning element of the hinge, so that the drive device, when the pushing element moves linearly, moves with the positioning element on the positioning element of the hinge in a direction of movement of the pushing element supported. As a result, the drive device can be positioned in the area of the first end section on the furniture part.

For example, the positioning member is arranged between the two drive elements. For example, the positioning element is present at a distance from a drive element. For example, the positioning element is present at a distance from all drive elements. It is conceivable that the positioning member is present between two drive elements in a direction transverse to the longitudinal extent of the drive elements. For example, a drive element is relatively movable to the positioning element. For example, all drive elements are movable relative to the positioning element. For example, the positioning member is present in a fixed position relative to the housing of the drive device.

For example, when the drive device is in the arranged state on the furniture, the positioning element is present on the positioning element of the hinge. For example, this indicates position ierorgan a connecting organ. For example, the positioning element has a connecting element. For example, the connecting member and the connecting element are designed in the form of a tongue-and-groove connection, so that the positioning member and the positioning element are fixed to one another in the arranged state of the drive device on the furniture by means of the tongue-and-groove connection in a direction transverse to the direction of movement of the push element. For example, the connecting element is present in the form of a recess on the positioning element. For example, the connecting element is present in the form of a survey or in the form of a nose on the positioning element.

It is also proposed that the positioning member of the drive device has a fixing member, by means of which the positioning member can be connected to the positioning element of the hinge in the arranged state. As a result, the drive element can be fixed in position on the hinge.

For example, the fixing element is in the form of a screw, a rivet, a bolt or a connecting pin. For example, in the arranged state on the hinge, the positioning element can be connected to the positioning element by the fixing element. For example, there is a through opening and/or a through thread on the positioning member, so that the fixing member can engage through the through opening and/or through the through thread into the recess of the connecting member and cooperate with the connecting element of the hinge.

In one embodiment of the drive device, the drive device has a link guide on an outside of a base body of the drive device. As a result, the drive device can be attached to the furniture part in a comparatively flexible manner.

For example, the link guide is formed on an outside of the housing of the drive device. For example, the link guide includes a guide groove or a guide bar. It is conceivable that the link guide has a T-shaped guide groove. For example, the link guide includes two or more guide grooves or guide webs. For example, the link guide is formed on two or three of the outer sides of the base body. For example, the link guide is formed on exactly two or exactly three of the outer sides of the base body. For example, the guide groove of the link guide has an undercut.

For example, the link guide is each formed on a first and a second outside of the base body, the first and the second outside of the base body lying opposite one another and being spaced apart from one another. For example, in this case the link guides are mirror-symmetrical to one another.

It is also proposed that the link guide is formed on the outside of the base body in the area of the second end section of the drive device. As a result, the drive device can be secured to the furniture part in the area of the second end section.

For example, the base body or the housing of the drive device in the area of the second end section is smaller in external dimensions than the remaining base body or the remaining housing. As a result, a fastening element can be arranged on the drive device, so that a fastening element outside is present in the arranged state of the fastening element on the drive device flush with the outside of the base body in the area of the base body remaining in the area of the second end section.

A fastening element for fastening a drive device according to one of the aforementioned embodiments to the furniture part is also proposed, wherein the fastening element has a gripping section, wherein in the arranged state of the fastening element on the drive device, the fastening element surrounds the base body of the drive device with the gripping section on three sides of the base body and wherein the fastening element has a fastening section by means of which the fastening element can be fastened to the furniture part. For example, in the arranged state, the drive device can be fixed to the furniture part by the fastening element in a direction transverse to the direction of movement of the push element. It is also conceivable that, in the arranged state, the drive device can be fixed in the direction of movement of the push element by the fastening element on the furniture part. As a result, the drive device can be fastened comparatively flexibly to the furniture part both when the furniture part stops to the left on the furniture body of the furniture and when the furniture part stops to the right on the furniture body of the furniture.

For example, the encompassing section is U-shaped, so that the encompassing section of the fastening element slides onto the base body of the drive device in a direction transverse to the longitudinal axis of the drive device bar or attachable, whereby the encompassing section in the arranged state rests with the insides of the encompassing section on the outsides of the base body of the drive device. For example, the encompassing section is present as a U-profile, as a U-angle and/or as an angle element.

For example, the fastening element is made of plastic and/or metal. For example, the encompassing section extends along a longitudinal axis of the fastening element and the fastening section is designed to project transversely to the longitudinal axis on the encompassing section. For example, the encompassing section comprises a first side element, a second side element and a third side element, wherein the second side element connects the first and third side elements to one another, so that a U-profile is formed. For example, the first side element is connected to the second side element at a first end and the fastening section is arranged at a second end of the first side element. For example, the fastening section has a mounting element which is coordinated with a fastening element of the furniture, so that the fastening element can be fixed to the furniture, for example to the furniture part, by means of the fastening section. For example, the fastening section extends in one plane and the second side element extends in a further plane, the extension planes of the fastening section and the second side element being parallel to one another and spaced apart from one another.

It is also proposed that a link element is formed on the encompassing section, which in the arranged state engages in a link guide of the base body of the drive device, the link element and the link guide being coordinated with one another in such a way that the encompassing section of the fastening element can be pushed onto the base body of the drive device. As a result, the fastening element can be fixed comparatively flexibly to the drive device. For example, this enables the drive device to be mounted using the fastening element for a left-hand stop as well as for a right-hand stop.

For example, a link element is formed on one inside, on two insides or on three insides of the encompassing section. It is conceivable that there is a link element on the first and third side elements of the encompassing section.

For example, the link element and the link guide are in the form of a tongue and groove connection. It is conceivable that the link element is designed in the form of a web protruding from the inside of one of the three side elements of the encompassing section. For example, the link element is present as a T-shaped web protruding from the surrounding section. As a result, the drive device and the fastening element are fixed to one another in the mutually arranged state in a direction transverse to an extension direction of the link element or the web. For example, the link element is designed to be insertable into the link guide in the direction of extension.

An exemplary embodiment of the invention is a hinge, in particular a furniture hinge, wherein in the arranged state of the hinge on a piece of furniture, the hinge connects a furniture part of the piece of furniture in an articulated manner to a furniture body of the piece of furniture, an adapter element being present on a second hinge arm of the hinge, wherein the Adapter element is designed such that the drive element of the drive device can be pivotally connected to the adapter element. This makes it comparatively easy to connect the hinge to a drive device. For example, this makes it possible to achieve a comparatively mechanically effective connection of a drive device to the hinge. For example, this allows the adapter element to be retrofitted to the hinge.

For example, the adapter element is arranged in a fixed position, for example in a non-detachable manner, on the second hinge arm. For example, the drive element can be connected to the adapter element of the hinge. For example, the drive element can be pivotally movable, e.g. rotatably movable, and can be fixed to the adapter element. For example, a rotation axis is formed on the adapter element, which can be connected to the drive element.

It is also proposed that a support element is present on the hinge, the support element being attached to a first hinge arm of the hinge, the hinge being able to be fixed to the furniture part via the first hinge arm, the support element being present as an angled angle element, the support element having a has a first support element section, wherein the first support element section is connected to the hinge, the support element having a second support element section, the first and second support element sections being angled to one another, a positioning element being present on the second support element section, wherein in the arranged state of the drive device according to one of the previously mentioned embodiments on the hinge of the second support element section comes into contact with the first end section of the drive device, so that the positioning element supports and positions the drive device.
