Description

[0001] "Drive device for moving a piece of furniture"

[0002] State of the art

[0003] In the case of furniture and household appliances with movably mounted furniture parts such as doors or flaps, various arrangements are known for movably attaching the furniture part to a body of the furniture or household appliance. When the furniture or household appliance is in use, the furniture part can be moved relative to the body using the hinge arrangement, for example, about a horizontally or vertically aligned pivot axis in order to be able to access the interior of the body and, when the furniture part is closed, to separate the interior from the outside. The furniture part can usually be moved manually and / or by a drive.

[0004] For furniture and household appliances such as cupboard furniture or refrigerators or freezers, compact and mechanically stable hinge assemblies are tailored to the specific use on the furniture or household appliance. This means that a hinge assembly designed and proven as a standard product can be used in a wide variety of applications. The hinge assembly is generally connected to the carcass and the furniture part. For mass products such as refrigerators and freezers, it is desirable to design the furniture or household appliance and the hinge assembly accordingly, thus enabling standardization. This means that proven hinge assemblies can be used universally without any changes in their design for a wide variety of different furniture and household appliances. This is advantageous both economically and when assembling such furniture and household appliances.

[0005] A disadvantage, especially when used on a refrigerator or freezer, is that hinge arrangements must be adapted to specific attachment points on the refrigerator or freezer, or on its movable furniture part. Object and advantages of the invention

[0006] The object of the present invention is to improve a hinge assembly mentioned above and / or an associated piece of furniture or household appliance from an economic and technical perspective. In particular, the object of the present invention is to further develop the hinge assembly and / or the associated piece of furniture or household appliance with a view to simplifying the assembly of the hinge assembly and / or increasing the ease of use of the piece of furniture or household appliance for a user.

[0007] This problem is solved by the independent claims. The dependent claims are directed to expedient and advantageous developments of the invention.

[0008] The invention is based on a drive device for moving a furniture part, wherein the furniture part can be movably linked to a furniture body via a hinge, wherein the drive device can be connected to the hinge at a first end section of the drive device, wherein the drive device can be fixed to the furniture part with a second end section of the drive device, wherein the first and the second end section are opposite one another and spaced apart from one another, wherein in the arranged state of the drive device on the furniture and of 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 the hinge arm and thus the furniture part can be moved by a movement of the drive element,wherein the drive element is pivotally connected to a linearly movable thrust element of the drive device by a first end of the drive element, and wherein, when the drive device is arranged on the hinge, the drive element is pivotally connected to the hinge arm of the hinge by a second end of the drive element. This provides a drive device that can be used relatively flexibly.

[0009] For example, the furniture comprises a furniture body and a furniture part, wherein the furniture part is designed to be movable relative to the furniture body and arranged on the furniture body. For example, the furniture is present 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 fridge-freezer combination.

[0010] For example, the hinge is designed as a refrigerator hinge, as a freezer hinge and / or as a fridge-freezer combination hinge. For example, fastening elements on which the hinge can be arranged are provided on the furniture carcass and / or on the furniture part. It is conceivable that fastening elements are provided on the furniture part and / or on the furniture carcass in such a way that the furniture part can be secured to the furniture carcass in the form of a door, both as a left-hand hinge and as a right-hand hinge. For example, the furniture part has fastening elements on a first side and on a second side for fastening the hinge, the fastening elements on the first side being opposite and spaced from the fastening elements on the second side.

[0011] For example, the hinge comprises a first hinge arm and a second hinge arm, wherein the first and second hinge arms are hingedly connected to one another via a third and fourth hinge arm. For example, the hinge comprises a fifth hinge arm which is hingedly connected to the second hinge arm. For example, the first hinge arm is designed to be arranged on a furniture part. For example, the fifth hinge arm is designed to be arranged on a furniture carcass.

[0012] For example, the drive device has a base body. For example, the base body is cuboid-shaped, 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 a hollow body and that one end face of the base body is open.

[0013] It is conceivable for the base body to be in the form of a housing. For example, the housing of the drive device is cuboid-shaped. For example, the housing is in the form of a hollow body. It is conceivable for the housing, in particular the hollow body, to be open on one side. For example, the drive element or the thrust element extends through the open side of the housing.

[0014] 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.

[0015] For example, the drive element is designed in the form of an angular element. It is conceivable that the drive element is arcuate and / or curved. It is conceivable that the drive element is a metal part. It is also conceivable that the drive element is a stamped component and is punched out of sheet metal. For example, the first and second ends of the drive element are opposite one another and spaced apart from one another. For example, the drive element is connected to the thrust element via a pivot bearing so that it can pivot, e.g. rotate.

[0016] It is further proposed that the drive device comprise two drive elements, wherein the drive elements are spaced apart from one another in the width direction of the drive device. This improves the transmission of force from the drive device to the hinge.

[0017] For example, the drive device comprises two drive elements, e.g. exactly two drive elements. For example, the plurality of drive elements are identically designed. For example, each drive element is connected to the thrust element by a first end of the respective drive element. For example, the two or more drive elements are spaced apart 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, e.g. in a direction perpendicular to their longitudinal axes.

[0018] It is also proposed that the drive device have a positioning member at the first end portion, wherein the positioning member is designed to interact with a positioning element of the hinge, so that during a linear movement of the sliding element, the drive device is supported by the positioning member on the positioning element of the hinge in a direction of movement of the sliding element. As a result, the drive device can be positioned in the region of the first end portion on the furniture part.

[0019] For example, the positioning member is arranged between the two drive elements. For example, the positioning member is spaced from one drive element. For example, the positioning member is spaced from all drive elements. It is conceivable that the positioning member is located between two drive elements in a direction transverse to the longitudinal extent of the drive elements. For example, one drive element is movable relative to the positioning member. For example, all drive elements are movable relative to the positioning member. For example, the positioning member is fixed in position relative to the housing of the drive device.

[0020] For example, when the drive device is mounted on the furniture, the positioning member is present adjacent to the positioning element of the hinge. For example, the positioning member comprises a connecting member. For example, the positioning element comprises a connecting element.

[0021] 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 secured to one another by means of the tongue and groove connection in a direction transverse to the direction of movement of the sliding element when the drive device is mounted on the furniture. For example, the connecting member is provided in the form of a recess on the positioning member. For example, the connecting element is provided in the form of a protrusion or in the form of a lug on the positioning element.

[0022] It is also proposed that the positioning member of the drive device comprise a fixing member by means of which, in the arranged state, the positioning member can be connected to the positioning element of the hinge. This allows the drive member to be fixed in position on the hinge.

[0023] For example, the fixing member is in the form of a screw, a rivet, a bolt, or a connecting pin. For example, when mounted on the hinge, the positioning member can be connected to the positioning element by the fixing member. For example, a through-hole and / or a through-thread is provided on the positioning member, so that the fixing member can engage through the through-hole and / or the through-thread into the recess of the connecting member and interact with the connecting element of the hinge.

[0024] In one embodiment of the drive device, the drive device has a guide slot on the outer side of a base body of the drive device. This allows the drive device to be attached to the furniture part with comparative flexibility.

[0025] For example, the link guide is formed on an outer side of the housing of the drive device. For example, the link guide comprises a guide groove or a guide web. It is conceivable that the link guide has a T-shaped guide groove. For example, the link guide comprises 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.

[0026] For example, the guide rails are formed on a first and a second outer side of the base body, wherein the first and second outer sides of the base body are opposite one another and spaced apart from one another. For example, the guide rails in this case are mirror-symmetrical to one another.

[0027] It is also proposed that the slotted guide is formed on the outside of the base body in the region of the second end section of the drive device. This enables the drive device to be secured to the furniture part in the region of the second end section. For example, the base body or the housing of the drive device is smaller in terms of its external dimensions in the region of the second end section than the remaining base body or the remaining housing. This enables a fastening element to be arranged on the drive device so that, when the fastening element is arranged on the drive device, the outside of the fastening element is flush with the outside of the base body in the area of ​​the base body remaining up to the region of the second end section.

[0028] 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 an encompassing section, wherein in the arranged state of the fastening element on the drive device the fastening element encompasses the base body of the drive device with the encompassing 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 fastened to the furniture part by means of the fastening element in a direction transverse to the direction of movement of the pushing element. It is also conceivable that in the arranged state the drive device can be fastened to the furniture part by means of the fastening element in the direction of movement of the pushing element.This allows the drive device to be attached comparatively flexibly to the furniture part both when the furniture part is hinged to the left on the furniture body and when the furniture part is hinged to the right on the furniture body.

[0029] For example, the encompassing section is U-shaped, so that the encompassing section of the fastening element can be pushed or plugged onto the base body of the drive device in a direction transverse to the longitudinal axis of the drive device, whereby the encompassing section, in the arranged state, rests with its inner sides against the outer sides of the base body of the drive device. For example, the encompassing section is provided as a U-profile, as a U-angle, and / or as an angle element.

[0030] 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 formed on the encompassing section so as to protrude transversely to the longitudinal axis. 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 the third side element 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 member which is matched to 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.

[0031] For example, the fastening section extends in one plane and the second side element in a further plane, wherein the extension planes of the fastening section and the second side element are parallel to one another and spaced apart from one another.

[0032] It is also proposed that a link element be formed on the encompassing section, which, when arranged, engages in a link guide of the base body of the drive device, wherein the link element and the link guide are 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. This allows the fastening element to be secured to the drive device relatively flexibly. For example, this allows the drive device to be mounted using the fastening element for a left-hand stop as well as for a right-hand stop.

[0033] For example, a guide element is formed on one inner side, on two inner sides, or on three inner sides of the encompassing section. It is conceivable that a guide element is present on each of the first and third side elements of the encompassing section.

[0034] For example, the link element and the link guide are in the form of a tongue and groove connection. It is conceivable for the link element to be designed in the form of a web protruding from an inner side of one of the three side elements of the encompassing section. For example, the link element is provided as a T-shaped web protruding from the encompassing section. As a result, the drive device and the fastening element, when arranged next to one another, are fixed to one another in a direction transverse to an extension direction of the link element or of the web. For example, the link element is designed so that it can be pushed into the link guide in the direction of extension.

[0035] An exemplary embodiment of the invention is a hinge, in particular a furniture hinge, wherein when the hinge is arranged on a piece of furniture, the hinge connects a furniture part of the furniture to a furniture carcass of the furniture, wherein an adapter element is provided 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. As a result, the hinge can be connected to a drive device relatively easily. For example, this enables a relatively mechanically effective connection of a drive device to the hinge. For example, this enables the adapter element to be retrofitted to the hinge.

[0036] For example, the adapter element is arranged in a fixed position, e.g., non-detachably, on the second hinge arm. For example, the drive element is connectable to the adapter element of the hinge. For example, the drive element is 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 is connectable to the drive element.

[0037] It is also proposed that a support element is provided on the hinge, wherein the support element is fastened to a first hinge arm of the hinge, wherein the hinge can be fixed to the furniture part via the first hinge arm, wherein the support element is provided as an angled angle element, wherein the support element has a first support element section, wherein the first support element section is connected to the hinge, wherein the support element has a second support element section, wherein the first and the second support element section are angled to one another, wherein a positioning element is provided on the second support element section, wherein in the arranged state of the drive device according to one of the aforementioned embodiments on the hinge, 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. This makes the drive device relatively easy to position on the hinge.

[0038] For example, the support element is non-detachably connected to the first hinge arm. For example, the support element is joined, riveted and / or tangled to the first hinge arm. For example, the support element is designed as an angled plate. It is conceivable for the positioning element to be present on the support element so as to protrude from the second support element section. It is also conceivable for the positioning element to be designed as a depression or as a recess on the second support element section. For example, the positioning element is angled to or bent over from the second support element section on the second support element section. As a result, the support element is designed to be comparatively cost-effective and / or stable.

[0039] Furthermore, a drive unit is proposed, wherein the drive unit comprises a drive device according to one of the above-mentioned embodiments and a fastening element according to one of the above-mentioned embodiments.

[0040] A furniture part movement unit is also proposed, wherein the furniture part movement unit comprises a drive unit according to one of the above-mentioned embodiments and two hinges according to one of the above-mentioned
