Exemplary embodiments of the present invention relate to a furniture or household appliance element.
Such furniture or household appliance elements, such as shelves or racks, in which a body part mounted in a support body so that it can rotate and move in translation at the same time, are known, for example, from DE 10 2019 109 866 A1.
A translation-rotation bearing is used to perform the translation-rotation movement of the body part.
Particularly in the case of larger and/or taller furniture or household appliance elements, such as refrigerators and freezers or wine coolers, it is necessary to provide additional support for the movement of the translational-rotationally movable body part for reasons of stability.
For this purpose, it is known from DE 10 2019 132 207 A1, for example, to arrange a guide bearing between the cover plates of the support body and the body part, with which the translational-rotational movement is additionally guided.
Particularly when a cover support plate is arranged covering both the fixed support body and the translational-rotationally movable body part, it is desirable to precisely define the vertical distance between the cover support plate of the support body and the cover plate of the body part or between the base support plate of the support body and the base plate of the body part in order to keep the desired distances between components of the furniture or household appliance element constant.
Exemplary embodiments of the present invention are directed to preventing the cover support plate or the base plate of the body part from lowering during the translational-rotational movement of the body part, in particular when a first and second body part are arranged side by side in a furniture or household appliance element.
The furniture or household appliance element according to the invention has a support body with a base support plate, a cover support plate, and optionally at least one side wall, as well as a body part that is mounted so as to be simultaneously movable in translation and rotation relative to the support body and has a base plate, a cover plate and at least one side wall.
A guide bearing is arranged between the cover support plate and the cover plate and/or between the base support plate and the base plate.
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 cover support plate and the cover plate or the base support plate and the base plate.
Furthermore, the guide bearing has a linear guide with connecting parts that can be displaced relative to one another in a direction of translation, one of which is arranged on the cover support plate or the cover plate and the other of which is mounted on the other of the cover support plate or the cover plate by means of a pivot bearing and/or one connecting part is arranged on the base support plate or the base plate and the other is mounted on the other of the base support plate or the base plate by means of a pivot bearing.
The guide element is designed as a support element supported on or in the guide cam track, whereby the position of the guide element can be variably adjusted perpendicular to the plane of the cover support plate or the base support plate.
By providing such a guide element designed as a support element, it is possible in a simple way to fix the vertical distance between the cover support plate of the support body and the cover plate of the body part or between the base support plate of the support body and the base plate of the body part to a precisely defined dimension.
The variable adjustability makes it possible to compensate for height tolerances of the furniture or household appliance element in particular.
According to a preferred embodiment, the guide element has a roller arranged on a thrust bearing that can roll along the bottom of the guide cam track.
This enables a smooth translational-rotational movement of the body section relative to the support body.
In a preferred further development, the thrust bearing has a thrust bearing receptacle provided with a threaded bolt, onto which a thrust bearing ring can be fitted, to the free end of which, facing away from the threaded bolt, a roller holder is fastened, in which the roller is rotatably mounted.
This ensures reliable support for the guide element.
According to an alternative embodiment, the guide element has a ball that can roll along the bottom of the guide cam track and is spring-mounted in a sleeve.
According to an advantageous further development, this sleeve has an internal thread in which a threaded bolt is accommodated in a rotationally adjustable manner, thus ensuring easy height adjustment.
According to a further alternative embodiment, the guide element has a roller that can roll on a side surface of the guide cam track. The roller is attached to an axle, which is held stationary in a bushing in the direction of its longitudinal axis and rotatable about its longitudinal axis. The bushing can be clamped to the guide bearing and also enables simple height adjustment.
In a preferred further development of this design variant, a clamping lever that fixes the bushing in a clamping position is provided for clamping the bushing.
This clamping lever preferably has a clamping body with a bushing holder that circumferentially encloses the bushing and a lever arm. The guide bearing here has a head piece with two retaining plates aligned parallel to each other with respective recesses in which the bushing is accommodated in a circumferentially guided manner, whereby the clamping lever is accommodated in a receiving space between the retaining plates and, in the clamping position, the clamping body is pressed against a clamping wall of the guide bearing with a partial surface of the wall forming the bushing receptacle bearing frictionally against a partial surface of the outer casing surface of the bushing.
According to a further preferred further development, the axle has a shoulder for fixing the roller in place on the axle.
A bearing is mounted on the axle on the side of the shoulder facing away from the roller. The bearing is designed in particular as a support or ball bearing.
In a special further development, the guide cam track has a running slope for vertical support of the roller.
According to a further preferred embodiment, the linear guide is formed from a pull-out guide, with a guide rail arranged on the cover support plate or the cover plate and/or on the base support plate or the base plate and at least one running rail mounted on it in a displaceable manner, the guide element being fixed to a plate-shaped connecting element of the guide bearing.
The arrangement of the guide element on the connecting element of the guide bearing enables simple assembly.
The connecting element is preferably attached to the at least one running rail of the linear guide.
The guide cam track is preferably connected to the cover plate of the body part and the at least one running rail of the linear guide is connected to the cover support plate of the support body via the connecting plate.
According to a further embodiment, the thrust bearing or the threaded bolt is fixed to the connecting element of the guide bearing.
According to an advantageous further development, the threaded bolt is fixed axially to the threaded bolt in a threaded sleeve arranged on a head piece of the connecting element.
According to a further embodiment, the guide element has a roller that can roll on a side surface of the guide cam track, whereby the roller is attached to an axle that can be clamped in a vertical adjustment in the direction of its longitudinal axis.
This enables simple and precise adjustment of the guide element in the vertical direction depending on the distance between the connecting element and the guide cam track.
According to an advantageous further development, the vertical adjustment has a bearing housing attached to the connecting element, an adjusting body that is accommodated in the bearing housing so as to be vertically displaceable and in which the axis of the guide element is fixed, and a detent lever for latching fixation of the adjusting body relative to the bearing housing.
Preferred embodiments are explained in more detail below with reference to the accompanying drawings, wherein:
In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the furniture element, the support body, the body part, the cover plate, the guide bearing, the guide cam track, the linear guide, the guide element and the like selected in the respective figures. These terms are not to be understood restrictively, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.
In
In the following, the furniture or household appliance element 1 is referred to as furniture element 1 for short for ease of reading. A corresponding household appliance element, in particular a refrigerator or freezer element or a wine cooler element, can be constructed in the same way as the furniture or household appliance element 1 shown as a furniture element.
The support body 2 has at least one base support plate 21 and one cover support plate 22 as well as at least one side wall 23 connected to the base support plate 21 and the cover support plate 22. The front of the support body 2 is closed here, for example, by a swing door 24.
The body part 3 has at least one base plate 31 and one cover plate 32 as well as at least one side wall 33 connected to the base plate 31 and the cover plate 32, in the embodiment shown here two side walls 33. The side walls are covered on the outside by panels 34. The interior of the body part 3 is subdivided here, by way of example, into a plurality of compartments arranged one above the other by a plurality of shelves 35 fixed to the side walls 33.
The length of the base support plate 21 of the support body 2 extends over the entire surface of the furniture element 1. The same applies to the cover support plate 22, which covers both the upper end of the support body 2 and the upper end of the body part 3, as shown in
Alternatively, the support body 2 can also be designed as a wall bracket with cover support plate 22 and base support plate 21, for example if the furniture or household appliance element 1 is arranged in a corner or niche of a room. Accordingly, a side wall 23 connecting the cover support plate 22 and base support plate 21 is not necessary in such an embodiment.
As shown in
Such a guide bearing 4 can also be arranged between the base support plate 21 and the base plate 31.

As shown in
It is also conceivable to attach the guide element 8 directly to the cover support plate 22 of the support body 2.
Furthermore, the guide bearing 4 has a linear guide 7 with connecting parts that can be displaced relative to one another, one of which is arranged on the cover support plate 22 or the cover plate 32 and the other of which is mounted on the other of the cover support plate 22 or the cover plate 32 by means of a pivot bearing 12.
When the guide bearing 4 is arranged in the base area of the body part 3, one connecting part is accordingly arranged on the base support plate 22 or the base plate 32 and the other is mounted on the other of the base support plate 22 or the base plate 32 by means of the pivot bearing 12.
The guide element 8 or the further embodiment example of a guide element 9 explained below is designed as a support element supported on or in the guide cam track 5.
In addition to supporting the translational-rotational movement of the body part 3, the guide element 8, 9 serves to fix the vertical distance between the cover support plate 22 of the support body 2 and the cover plate 32 of the body part 3 or between the base support plate 21 of the support body 2 and the base plate 31 of the body part 3 to an exactly defined dimension in the case of an arrangement of the guide bearing 4 in the bottom area of the body part 3.
The first embodiment of such a guide element 8 shown in
The thrust bearing has a thrust bearing receptacle 85 provided with a threaded bolt 851, onto which a thrust bearing ring 84 can be fitted, at the free end of which, facing away from the threaded bolt 851, a roller holder 83 is fastened, here in the form of a pin 854, in which the roller 81 is rotatably mounted.
As shown in
The roller holder 83 itself is attached to the thrust bearing receptacle 85, preferably rotatably offset with the pin 854 of the thrust bearing receptacle 85.
The thrust bearing or the threaded bolt 851 is preferably fixed to the connecting element 6 of the guide bearing 4. In this case, the thrust bearing receptacle 85 is designed at an end remote from the pin 854 as a threaded bolt 851, which is preferably fixed in a threaded sleeve 64 arranged on a head piece 63 of the connecting element 6 so as to be axially adjustable relative to the threaded bolt 851.
The thrust bearing ring 84 is clamped between a collar 852 of the thrust bearing receptacle 85 and a connecting piece 832 of the roller holder 83, which connects the legs 831 to one another, in order to enable a rotary movement about a longitudinal axis of the thrust bearing receptacle 85 of the roller holder 83. The thrust bearing ring 84 has a receptacle 841 through which a neck piece 853 of the thrust bearing receptacle 85 is passed.
An alternative embodiment of such a guide element is shown in
This embodiment of the guide element 9 also has a threaded bolt 91 which, like the threaded bolt 851 of the embodiment described above, is preferably fixed in a threaded sleeve 64 arranged on the head piece 63 of the connecting element 6 so as to be axially adjustable relative to the threaded bolt 91.
The threaded bolt 91 is screwed into a sleeve 92 with an internal thread 96, at the end of which, at a distance from the threaded bolt 91, a ball 93 is accommodated, which is held by a collar 95 at the lower end of the sleeve 92 so as to project from the sleeve 92 by a predetermined amount. The collar 95 prevents the ball 93 from falling out.
As shown in
The guide cam track 5 preferably has eyelets 52 on its outer sides for fixing, in particular screwing, the guide cam track 5 to the cover plate 32 or to the base plate 31 of the body part 3.
Similarly, eyelets 62 are formed on the side of the connecting element 6 on a main body 61, to which the running rails 72 of the linear guide 7 are attached in the example shown in
The guide rail 71 of the linear guide 7 is rotatably mounted on a pivot bearing 12.
The pivot bearing 12 has a pivot pin that is arranged on a circular mounting plate 11, which is attached to the cover plate 32 or base plate 31 of the body part 3. The circular shape serves to distribute forces over as large an area as possible. Other designs are also conceivable.
The axis of rotation of the pivot bearing 12 is mounted in a pivot axis bearing (not shown) provided for this purpose on the underside of the guide rail 71 of the linear guide 7 in order to enable the translational-rotational movement of the body part 3 relative to the support body 2.
The pivot axis can also be axially adjustable or telescopically mounted in the pivot axis bearing. This ensures that the entire guide bearing 4 is evenly supported.
The axle 182, 192 is thereby held stationary in the direction of its longitudinal axis and rotatable about its longitudinal axis in a bushing 184, 194 surrounding the axle 182, 192 in the region of an upper section remote from the roller, for example with the aid of a disc 186, 196 attached to the upper end of the axle 182, 192 and resting on an end edge of the bushing 184, 194, as shown in
The bushing 184, 194 itself can be clamped to the guide bearing 4. A clamping lever 13 fixing the bushing 184, 194 in a clamping position is preferably provided for clamping fixation of the bushing 184, 194.
