Description

Field of the Invention

[0001] The present invention relates to a furniture or household appliance element according to the preamble of claim 1. Background Art

[0002] Such furniture or household appliance elements, such as shelves or brackets, are known, for example, from DE 10 2019 132 207 A1, in which a body part is mounted in a support body so that it can move both rotationally and translationally.

[0003] For the translational and rotational movement of the body part, guide bearings are arranged here in particular to guide the translational and rotational movement.

[0004] Especially when arranging a top support plate covering both the fixed support body and the translatable and 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, so as to be able to precisely define the desired distances between the components of the furniture or household appliance element, or to be able to compensate for manufacturing tolerances. Summary of the Invention

[0005] The object of the present invention is to provide a furniture or household appliance element with which the height adjustment of a body part that can move translationally and rotationally can be carried out in a simple manner.

[0006] This object is achieved by a furniture or household appliance element having the features of claim 1.

[0007] The furniture or household appliance element according to the present invention has a support body having a base support plate, a top support plate and at least one side wall. In addition, the furniture or household appliance element has a body part having a base plate and at least one side wall, and the body part is mounted so as to be able to translate and rotate relative to the support body simultaneously.

[0008] Guide bearings are arranged between the base support plate and the base plate so that the body part can move relative to the support body both translationally and rotationally.

[0009] The guide bearings have at least one guide cam track and a guide element guided in or on the guide cam track, which are arranged on opposite surfaces of the base support plate and the base plate.

[0010] The guide bearings also have a linear guide having at least one first track and at least one second track, and the second track can be displaced relative to the first track in the translational direction.

[0011] At least one first track and at least one second track are arranged on opposite surfaces of the base support plate and the base plate via pivot bearings.

[0012] The guide bearing has a height adjustment device, and the height adjustment device has a rotation mechanism that can be variably adjusted perpendicular to the plane of the base support plate.

[0013] By providing the height adjustment device, the height of the guide bearing can be increased or decreased in a simple manner, so that, for example, the height of the panel of a furniture or household appliance element relative to an adjacent support body can be precisely adjusted.

[0014] Advantageous embodiments of the present invention are the subject matter of the dependent claims.

[0015] According to an advantageous embodiment of the present invention, the rotation mechanism has a rotary cylinder provided with an external thread that meshes with an internal thread of another component of the height adjustment device.

[0016] Via such a threaded adjustment, the height adjustment can be achieved in a very simple manner by rotating the rotary cylinder.

[0017] In a preferred embodiment, the component having the internal thread is attached to a pivot bearing.

[0018] According to a preferred further aspect, the height adjustment device has a flange attached to the guide bearing, the base support plate or the base plate, and a planetary gear mechanism having an adjustment gear and at least one planetary gear is accommodated in the flange, and the planetary gear meshes with the rotary cylinder.

[0019] Due to the gear reduction of the planetary gear mechanism, providing such a planetary gear mechanism for adjusting the rotary cylinder enables the use of a very low adjustment force.

[0020] At the same time, using such a planetary gear mechanism ensures sufficient suppression of the height adjustment so that it does not change accidentally or only due to weight.

[0021] According to a further embodiment, the component attached to the pivot bearing by the internal thread is designed or arranged as a fixed housing on a guide cam track.

[0022] According to the first embodiment, the housing and the guide cam track are designed as one piece.

[0023] The one-piece design of the housing and the guide cam track provides the advantage of easy installation.

[0024] According to an alternative embodiment, the component having the internal thread is attached as an independent component within the housing.

[0025] In a preferred alternative embodiment, the height adjustment device includes a housing having an internal thread, and the rotary cylinder is rotatably accommodated therein, and the rotary cylinder is in the form of an adjustment wheel having an external thread.

[0026] Using this type of threaded connection also makes it easy to precisely adjust the height.

[0027] The housing and the rotary cylinder are preferably supported on opposite surfaces of a base support plate or substrate on the one hand and a guide bearing on the other hand.

[0028] Here, in order to ensure increased torsional protection, the height adjustment device has a support disk which has a web receiving portion extending radially with respect to the rotational axis of the rotary cylinder, and a web of the housing extending radially with respect to the rotational axis of the rotary cylinder projects into this web receiving portion.

[0029] Since the support disk and the housing with the internal thread do not rotate relative to each other, but only move relative to each other in the vertical direction, the web and the web support fix the support disk and the housing with the internal thread and prevent them from rotating.

[0030] The support disk is preferably attached to the surface of the base support plate, substrate or guide bearing, and the rotary cylinder is supported on the support disk.

[0031] The rotary cylinder and the support disk are preferably attached to a pivot bearing.

[0032] In both of the above-described embodiment variants, the internal thread and the external thread are preferably designed as trapezoidal threads, which enables height adjustment to be achieved with a smaller adjustment angle than in the case of standard threads.

[0033] According to yet another alternative embodiment, the height adjustment device includes a plate having a plurality of annularly arranged ramps, on which a counter plate having a plurality of annularly arranged ramps is placed, whereby the plate and the counter plate are supported on opposite surfaces of a base support plate or substrate on the one hand and a guide bearing on the other hand.

[0034] This ramp arrangement also allows the height of the main body part to be simply adjusted by rotating one of the plate or the counter plate.

[0035] The plate preferably contacts the pivot bearing, and the counter plate contacts the base support plate or substrate.

[0036] In order to adjust the height of the main body part during installation of the main 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 which is aligned with an opening in the substrate of the main body part.

[0037] According to a further preferred embodiment, the rotation mechanism of the height adjustment device has end stops for determining the minimum and maximum positions of the height adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In the following description of the drawings, terms such as top, bottom, left, right, front, and back specifically refer to the exemplary views and positions of furniture or household appliance components, support bodies, main body parts, guide bearings, height adjustment devices, etc. selected in the corresponding drawings. These terms should not be understood restrictively, that is, these references can be changed due to different working positions or mirror-symmetric designs, etc.

[0053] In Figures 1 to 4 , the reference numeral 1 is used to designate the overall embodiment of the furniture or household appliance component according to the present invention.

[0054] The furniture or household appliance component 1 shown here as a furniture component has a support body 2 and a main body part 3, and the main body part can be moved translationally and rotationally simultaneously.

[0055] Hereinafter, for the convenience of reading, the furniture or household appliance component 1 is simply referred to as the furniture component 1. The corresponding household appliance components, especially refrigerator or freezer components or wine cooler components, can be constructed in the same manner as the furniture or household appliance component 1 shown as a furniture component.

[0056] The support body 2 has at least one base support plate 21, a top support plate 22, and at least one side wall 23 connecting the base support plate 21 and the top support plate 22. The front part of the support body 2 is closed here, for example, by a swing door 24.

[0057] The main body part 3 has at least one base plate 31 and at least one side wall 33 connected to the base plate 31. In the embodiment shown here, there are two side walls 33.

[0058] The interior of the main body part 3 is subdivided here, for example, into a plurality of vertically stacked compartments by a plurality of shelves 34 fixed to the side walls 33 and the support webs 35.

[0059] The length of the base support plate 21 of the support body 2 extends over the entire surface of the furniture component 1. The same applies to the top support plate 22, which covers both the upper end of the support body 2 and the upper end of the main body part 3, as Figure 1 and Figure 2 shown.

[0060] As an example, as Figure 5 shown, the guide bearing 4 is arranged between the base support plate 21 and the base plate 31.

[0061] As Figures 5 to 9 , Figure 11 and Figure 12As shown, the guiding bearing 4 has a linear guide 6 which has a guide rail 61 attached to the base support plate 21 via a connecting plate 63, and a slide rail 62 which can be displaced relative to the guide rail in the translational direction A, and a pivot bearing 64 is attached to the slide rail.

[0062] The guiding bearing 4 further has height adjusting devices 7, 8, 9 which can be variably adjusted perpendicular to the plane of the base support plate 21 and have a rotating mechanism by which the height z of the main body part 3 can be adjusted, as shown by way of example Figure 3 and Figure 4 shown.

[0063] In Figures 7 to 11 the different embodiments shown, the height adjusting devices 7, 8, 9 are always arranged on the pivot bearing 64.

[0064] For example, it is also conceivable to arrange the height adjusting devices 7, 8, 9 directly below the base plate 31, the pivot bearing 64, or directly above the base support plate 21.

[0065] Furthermore, the guiding bearing 4 has a guiding cam track 5 and a guiding element 11 guided in or on the guiding cam track 5, which are arranged on opposite surfaces of the base support plate 21 and the base plate 31.

[0066] In the embodiment shown here, the guiding cam track 5 is arranged on the base plate 31, while the guiding element 11 is attached to the connecting plate 63 of the linear guide 6.

[0067] The following refers to Figures 5 to 8 describe the first embodiment of the height adjusting device 7.

[0068] The height adjusting device 7 according to the first embodiment has a flange 71 which can be attached to the base plate 31.

[0069] As Figure 8 shown, the flange 71 houses a planetary gear mechanism 72 which has an adjusting gear 721 and at least one planetary gear 722, and in the example of the embodiment four planetary gears 722 are shown, which mesh with a rotating cylinder 73.

[0070] For this purpose, an internal tooth part 732 is formed in the rotating cylinder 73, the teeth of which extend in the vertical direction z, such that when the adjusting gear 721 rotates, the rotational movement is transmitted to the planetary gears 722 and from the planetary gears to the rotating cylinder 73.

[0071] The rotating cylinder 73 is screwed into a part attached to the pivot bearing 64, which part is provided with an internal thread 75, such that the vertical height z of the flange 71 relative to the guiding cam track 5 can be varied by rotating the rotating cylinder 73, as Figure 6and Figure 7 as shown

[0072] It is also conceivable to attach or form the internal thread 75 in another component of the height adjustment device 7.

[0073] In the preferred embodiment shown here, the component attached to the pivot bearing 64 is the housing 76, which is arranged in a fixed position on the guide cam track 5 and is particularly preferably designed as one piece with the guide cam track 5.

[0074] Furthermore, the housing 76 has a side wall 761 for vertically guiding the flange 71. For this purpose, as particularly Figure 8 shown, in addition to the base 712, the flange 71 has side walls 711 that extend vertically from the base and abut against the inner side of the side wall 761 of the housing 76.

[0075] It is also conceivable to fasten the internal thread 75 as a separate component in the housing 76.

[0076] As further Figures 5 to 8 shown, the flange 71 has a plurality of holes 714 through which fastening screws can pass, and the flange 71 can be fastened to the lower side of the base plate 31 with these screws.

[0077] The tool receiving portion 723 is provided at the center of the adjusting gear 721, and this bracket is aligned with Figure 3 and Figure 4 the opening 311 in the base plate 31 shown, so that the height adjustment device 7 can be easily accessed using a rotating tool (such as a multi-angle wrench).

[0078] Therefore, through the opening 311 in the base plate 31 and the opening in the flange 71, a polygonal groove can be achieved in the adjusting gear 721, and its rotation enables the height adjustment of the main body portion 3.

[0079] As further Figure 8 shown, the planetary gear 722 is preferably fixed to the cover 74, and this cover can be fixed to the rotating cylinder 73 so that it can rotate around the vertical rotation axis.

[0080] In Figure 9 and Figure 10 an alternative embodiment of the height adjustment device 8 shown, the height adjustment device 8 has a housing 81 with an internal thread 812, and a rotating cylinder 83 is rotatably accommodated therein, which is in the form of an adjusting wheel with an external thread 832.

[0081] In the shown embodiment, the internal thread 812 is arranged in the ring plate 811, and in this case, the ring plate can be fastened in contact with the lower side of the base plate 31.

[0082] The rotary cylinder 83, which is in the form of an adjustment wheel having an external thread 832 and a tool receiving portion 831, is rotatably received in the internal thread 812.

[0083] The rotary cylinder 83 is supported on a pivot bearing 64.

[0084] To ensure that the housing 81 is not fixed against rotation, the height adjustment device 8 also has a support disk 82 which has a web receiving portion 823 extending radially with respect to the axis of rotation of the rotary cylinder 83, into which a web 813 of the housing 81, which extends radially with respect to the axis of rotation of the rotary cylinder, projects.

[0085] In the exemplary embodiment shown, the support disk 82 and the rotary cylinder 83 are attached to the pivot bearing 64.

[0086] The web 813 is preferably formed on the lower side of the housing 81 facing the support disk 82.

[0087] In Figures 5 to 8 and Figure 9 and Figure 10 In the exemplary embodiment shown, the external threads 731 and 832 and the internal threads 75 and 812 are preferably designed as trapezoidal threads.

[0088] Figure 11 and Figure 12 Another alternative embodiment variant of such a height adjustment device 9 is shown.

[0089] The height adjustment device 9 shown in these figures comprises a plate 92 having a plurality of annularly arranged ramps 922, on which a counterplate 91 having a plurality of annularly arranged ramps 914 is placed, the plate 92 and the counterplate 91 being supported on the one hand on mutually opposite surfaces of a base support plate 21 or a base plate 31 and on the other hand on mutually opposite surfaces of a guide bearing 4.

[0090] In the exemplary embodiment shown, the plate 92 is attached to the pivot bearing 64. The ramps 922 are formed in a region 921 facing the base plate 31. The ramps 922 are provided with inclined surfaces.

[0091] The counterplate 91 placed on the plate 92 can be attached to the base plate 31 accordingly.

[0092] The counterplate 91 is also formed with a plurality of annular ramps 914 which are formed with inclined surfaces on the surface facing the plate 92.

[0093] In the preferred embodiment shown here, the counterplate 91 has a central region 912 which has a tool receiving portion 911, specifically in the form of a polygonal recess.

[0094] A plurality of wings 913 extend radially outward from the central region 912. Ramps 914 are formed on these wings 913, so that by inserting a tool into the tool receiving portion 911, rotation of the opposing plate 91 is achieved, thereby increasing or decreasing the distance between the central region 912 of the opposing plate 91 and the plate 92, and thus achieving height adjustment of the main body portion 3.

[0095] A common feature of all the height adjustment devices 7, 8, and 9 is that both the minimum and maximum height adjustment positions are ensured by fixed end stops.

[0096] In these design examples, the height adjustment devices (6, 7, 8) are arranged in the lower region between the main body portion 3 and the support main body 2. Of course, height adjustment devices can also be additionally or alternatively provided in the upper region between the support main body 2 and the main body portion 3.

[0097] The upper height adjustment device can be designed as described in the embodiment examples or differently designed.
