Description
[0001] The present invention relates to a furniture or household appliance element.
[0002] Such furniture or household appliance elements, such as shelves or racks, in which a body part is mounted in a support body that is simultaneously rotatably and translationally movable, are known, for example, from DE 10 2019 132 207 A1 or the subsequently published WO 2023 / 166145 A1.
[0003] To carry out the translational-rotational movement of the body part, a guide bearing is arranged here in particular, with which the translational-rotational movement is guided.
[0004] Particularly when arranging a top support plate that covers both the stationary support body and the translationally rotatable body part, it is desirable to precisely define the vertical distance between the base support plate of the support body and the base plate of the body part in order to precisely define desired distances between components of the furniture or household appliance element or to compensate for manufacturing tolerances.
[0005] From WO 2018 / 151123 A1, a furniture element is known with a support body and a body part contained therein and which can be extended out of it via a guide bearing, wherein the guide bearing is height-adjustable.
[0006] The object of the present invention is to provide a furniture or household appliance element with which a height adjustment of the translationally and rotationally movable body part is made possible in a simple manner.
[0007] This problem is solved by a furniture or household appliance element having the features of claims 1, 6 and 11.
[0008] The furniture or household appliance element according to the invention comprises a support body with a base support plate, a top support plate, and at least one side wall. The furniture or household appliance element further comprises a body part, which is mounted to be simultaneously translationally and rotationally movable relative to the support body and which has a base plate and at least one side wall.
[0009] To enable simultaneous translational and rotational movement of the body part relative to the support body, a guide bearing is arranged between the base support plate and the base plate.
[0010] The guide bearing has at least one guide cam track and a guide element guided in or on the guide cam track, which are arranged on mutually facing surfaces of the base support plate and the base plate.
[0011] The guide bearing also features a linear guide, with at least one first rail and at least one second rail which can be moved relative to it in a translational direction.
[0012] The at least one first rail and the at least one second rail are arranged via a pivot bearing on mutually facing surfaces of the base support plate and the base plate.
[0013] The guide bearing has a height adjustment device that is variably adjustable perpendicular to the plane of the base support plate and includes a rotary mechanism.
[0014] The rotary mechanism features a rotary cylinder with an external thread, which meshes with an internal thread of another component of the height adjustment device.
[0015] The component attached to the rotary bearing via the internal thread is designed or arranged as a housing fixed to the guide cam track.
[0016] By providing a height adjustment device, it is easily possible to increase or decrease the installation height of the guide bearing and thus, for example, to precisely adjust the height of the aperture of the furniture or household appliance element relative to an adjacent support body.
[0017] Height adjustment via such a threaded setting is made possible in a very simple way by turning the rotary cylinder.
[0018] Advantageous embodiments of the invention are the subject of the dependent claims.
[0019] In a preferred embodiment, the component having the internal thread is attached to the rotary bearing.
[0020] According to a preferred embodiment, the height adjustment device has a flange attached to the guide bearing, the base support plate or the base plate, in which a planetary gear with an adjusting gear and at least one planet gear is accommodated, which mesh with the rotary cylinder.
[0021] The provision of such a planetary gear for adjusting the rotary cylinder allows, on the one hand, the use of very small adjusting forces, due to the gear reduction of the planetary gear.
[0022] At the same time, the use of such a planetary gear ensures sufficient damping of the height adjustment, so that it does not change accidentally or solely due to weight force.
[0023] According to an initial design variant, this housing is formed in one piece with the guide cam track.
[0024] The one-piece design of the housing with the guide cam track offers the advantage of easier assembly.
[0025] In an alternative design variant, the component having the internal thread is attached as a separate component in the housing.
[0026] In a preferred alternative embodiment, the height adjustment device has a housing with an internal thread in which a rotary cylinder with an external thread, designed as an adjustment wheel, is rotatably mounted. To ensure increased anti-rotation protection, the height adjustment device has a support disc with radially extending web recesses extending to the axis of rotation of the rotary cylinder, into which radially extending webs of the housing project.
[0027] This variant also allows for precise height adjustment in a simple manner through the use of such a threaded connection.
[0028] The housing and the rotary cylinder are preferably supported on mutually facing surfaces of the base support plate or the base plate on the one hand and the guide bearing on the other.
[0029] Since the support disc and the housing with the internal thread do not rotate relative to each other, but only move in a vertical direction relative to each other, the webs and the web receptacles secure the support disc as well as the housing with the internal thread against rotation.
[0030] The support disc is preferably attached to the surface of the base support plate, the base plate or the guide bearing on which the rotary cylinder is supported.
[0031] The rotary cylinder and the support disc are preferably attached to the rotary bearing.
[0032] In both of the above-mentioned design variants, the internal thread and the external thread are preferably designed as trapezoidal threads, which allows for height adjustment with a smaller adjustment angle than is the case with standard threads.
[0033] According to a further alternative embodiment, the height adjustment device has a plate with several ring-shaped ramps, on which a counter plate with several ring-shaped ramps rests, wherein the plate and the counter plate are supported on mutually facing surfaces of the base support plate or the base plate on the one hand and the guide bearing on the other.
[0034] This type of ramp arrangement also allows for easy height adjustment of the body part by rotating one of the plates or the counter plate.
[0035] The plate is preferably located at the pivot bearing and the counter plate at the base support plate or the base plate.
[0036] In order to enable height adjustment of the body part in the installed state of the body part, according to a preferred embodiment, the flange, the rotary cylinder designed as an adjustment wheel or the counter plate is designed with a tool recess that is aligned with an opening in the base plate of the body part.
[0037] According to a further preferred embodiment, the rotary mechanism of the height adjustment devices has end stops for defining minimum and maximum positions of the height setting.
[0038] Preferred embodiments are explained in more detail below with reference to the accompanying drawings.
