Exemplary embodiments of the present invention relate to a storage shelf base for an item of furniture or household appliance and an item of furniture or household appliance.
Storage shelf bases of this type, in which a support plate and a storage shelf guided on the support plate are arranged on a base plate and can be moved simultaneously in rotation and translation, allow access to otherwise inaccessible surfaces in the storage space of an item of furniture or household appliance such as a refrigerator or freezer.
For example, DE 42 16 765 A1 discloses storage shelf bases equipped with a turntable where the turntable is installed directly in the base plate of the storage shelf base.
The post-published DE 10 2017 106 170 A1 discloses a storage shelf that is positively guided relative to the support plate and can be moved simultaneously in rotation and translation.
A disadvantage of these storage shelf bases is the relatively complex assembly of such a storage shelf base.
Exemplary embodiments of the present invention are directed to a storage shelf base for an item of furniture or household appliance that can be easily integrated into a body of the item of furniture or household appliance or retrofitted in a simple manner.
The storage shelf base has a support plate and, furthermore, a storage shelf that is positively guided relative to the support plate and can be moved simultaneously by rotation and translation, wherein the bearing surfaces of the support plate and the shelf facing one another have respective at least predominantly closed, circumferential running grooves in which rolling elements are guided.
The support plate is detachably attached to a base plate or detachably attached to the body of the furniture or household appliance by means of at least one adapter.
This makes it easy to attach the storage shelf that is movable rotationally and translationally to the body of the furniture or household appliance.
In one embodiment variant, the storage shelf base comprises a base plate that can be fixed in a stationary manner to the body of the furniture or household appliance. The support plate is preferably arranged on this base plate.
Preferably, the storage shelf base has a base plate and the adapter is designed as a base plate holder, which fixes the base plate to the body of the furniture or household appliance.
In accordance with an advantageous embodiment variant of the storage shelf base, the base plate holder at least partially embraces an edge of the base plate and has at least one first recess in which a connecting element extending from one edge of the support plate can be inserted, which connecting element, in the inserted state, is held positively or frictionally in the base plate holder.
Such base plate holders are often used, for example, for base plates designed as glass plates to fix the base plate to the body of the furniture or household appliance.
The insertion of corresponding recesses in this base plate holder is extremely easy, so that by slightly modifying the base plate holder, the support plate can be mounted for supporting the storage shelf.
The connecting element is preferably integrally formed on the support plate. It is also conceivable to manufacture such a connecting element as a separate component and attach it to the support plate.
The connecting element is designed as a hook in accordance with an advantageous embodiment variant, which engages behind a strip section of the base plate holder, which enables extremely simple mounting of the support plate to the base plate holder.
According to a further embodiment variant, the support plate has retaining elements engaging around the base plate.
Such a solution is particularly advantageous if the base plate holder is not available or is not suitable for holding the support plate.
Here, too, the retaining elements are preferably integrally formed on the support plate. It is also conceivable here to provide such retaining elements as separate components that are fastened to the support plate.
In accordance with an alternative embodiment variant, the base plate holder at least partially engages around one edge of the base plate. The support plate and the base plate holder have form-fit elements that allow the support plate to be fixed in a form-fitting manner to the base plate holder by a pivoting movement from a position of the support plate at an angle to the base plate to a position of the support plate resting on the base plate.
This allows the support plate to be mounted to the base plate holder and placed on the base plate by means of a simple pivoting movement.
For this purpose, recesses are preferably formed on the rear edge of the support plate facing the base plate holder, into which a hook element integrally formed on the base plate holder engages.
Such recesses and hook elements can be easily formed on the base plate holder or the base plate.
In order to also reliably prevent linear slippage of the storage shelf relative to the base plate, at least one recess is integrally formed in accordance with a further preferred embodiment in an underside of the support plate facing the base plate near the edge facing the base plate holder, into which recess, when the support plate is pivoted onto the support plate, a counter strip formed on the base plate holder protrudes.
For exact, especially central positioning of the storage shelf on the base plate, also transverse to the translation movement of the storage shelf, the contact surfaces of the respective side edges of the support plate lie close to the rear edge of the support plate on the respective stop surfaces of stops protruding from the base plate holder towards the support plate.
Due to the connection according to the invention, the support plate is detachably fixed and secured in position both vertically and horizontally. Unintentional loosening of the support plate or tilting forwards or slipping to the side are prevented.
According to a further advantageous embodiment variant of the invention, a tilting protection element is arranged on the support plate, the tilting protection element overlapping the upper edge of the shelf and serving to prevent a tilting movement of the storage shelf around a tilting axis parallel to the shelf surface. Alternatively, the tilting protection element can be designed in such a way that it engages in a groove in the storage shelf.
The advantage of such a tilting protection element is the prevention of a tilting movement of the storage shelf, especially when the load on the storage shelf is unevenly distributed with objects placed on the storage shelf.
According to a preferred embodiment variant, a section of the tilting protection element is located in a second recess of the base plate holder, whereby additional stabilization of the tilting protection element is achieved. The tilting protection element is designed as a catch hook according to a preferred embodiment variant, in particular as a C-shaped catch hook.
The storage shelf base according to the invention can preferably be used in an item of furniture or in a household appliance, especially in a refrigerator or freezer. In addition, the item of furniture or household appliance each has a body for accommodating the storage shelf base.
In the following, preferred embodiment examples of the invention are explained in more detail using the enclosed drawings, wherein:
In the following figure description, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the storage shelf base, the base plate, the support plate, the storage shelf, the base plate holder, the connecting 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 interpretation or the like.
In
The storage shelf base 1 has a base plate 2, which can be fixed in a stationary manner to a body 13, 14 of an item of furniture 11 or household appliance 12, and a support plate 3 arranged on the base plate 2.
On this support plate 3, there is a storage shelf 4, which can be simultaneously moved in rotation and in translation. For positively guided simultaneous rotational and translational movement, mutually facing bearing surfaces 31, 42 of the support plate 3 and the storage shelf 4 each have at least predominantly closed, circumferential running grooves (33, 34, 43, 44, 45, 46) in which rolling elements 10 are guided. The rolling elements 10 used here are in particular balls.
The support plate 3 is detachably fastened to the base plate 2 or, as shown in
It is also conceivable to fix the support plate 3 or the base plate 2 to the body 13, 14 of the item of furniture 11 or household appliance 12 by means of several such adapters. In the former case, the base plate 2 can also be omitted.
It is also conceivable to detachably fasten the support plate 3 to the base plate 2 using at least one adapter.
As shown in
The inner running groove 33 of support plate 3 is designed as a closed circumferential running groove. The outer running groove 34 is open towards a front side of storage shelf base 1.
For forced simultaneous rotational and translational movement of storage shelf 4, two partially overlapping inner running grooves 43, 44 and two likewise partially overlapping outer running grooves 45, 46 are each inserted into the bearing surface 42 of storage shelf 4. All running grooves 43, 44, 45, 46 are designed in this case as closed circumferential running grooves.
To prevent the loss of this rolling element 10, the rolling elements 10 are accommodated in a rolling element cage 9. The rolling element cage 9 here is in the form of a circular ring with four arms extending radially outwards from the circular ring, at each of whose free end a further rolling element 10 is accommodated.
Both the inner running grooves 33, 43, 44 and the outer running grooves 34, 45, 46 are shaped in such a way that, when force is applied to the storage shelf 4 in the horizontal direction, the storage shelf 4 can be moved from a starting point in accordance with the orientation of the storage shelf 4 shown in
The movement back to the starting position takes place in an equally simple manner by exerting force in the horizontal direction in the closing direction, in which the storage shelf 4 is moved further into the closing position while maintaining the initial direction of rotation, or by reversing the direction of rotation.
As shown in
For this purpose, the base plate holder 5 has two recesses 54, into which a respective connecting element 6 extending from one edge of the support plate 3 can be inserted and which are held in the inserted state in the base plate holder 5 by positive or frictional locking.
As shown in
The base plate holder 5 essentially consists of a strip-shaped base body 51 with a slot 52 extending over the longitudinal extension of the base body 51, which serves to accommodate a rear edge 22 of the base plate 2.
Above slot 52, a fastening strip 53 is integrally formed, which serves to fasten the base plate holder 5 to the body of the furniture or household appliance and with which the base plate 2 can be fixed to the body of the furniture or household appliance.
One or more first recesses 54 are introduced into this fastening strip 53 to accommodate the connecting element 6. Alternatively or additionally, there can be recesses on the support plate 3 which interact with corresponding connecting elements on the base plate holder 5, or both the support plate 3 and the base plate holder 5 can be equipped with interacting connecting elements.
An alternative embodiment variant of a base plate holder 5a, 5b is described below on the basis of
The base plate holder 5a, 5b in this embodiment variant consists of two separate base plate holders 5a and 5b, which, like the base plate holder 5 described above, have a respective slot 52a, 52b to accommodate a rear edge 22 of the base plate 2 and engage around the edge 22 of the base plate 2.
The two base plate holders 5a, 5b each have a side edge border 57a at one side edge, wherein in
The two base plate holders 5a, 5b are, as shown in
A hook element 53a, 53b is integrally formed in each case on the upper side of a base body 51a, 51b of the base plate holders 5a, 5b facing the support plate 3. The hook element 53a, 53b in the embodiment variant shown here extends vertically upwards from an area of the base body 51a, 51b close to the rear edge 22 and is preferably bent forward by about 90°, i.e., towards the center of the upper side 21 of the base plate 2.
As shown in
The hook elements 53a, 53b engage in recesses 37 on the rear edge 36 of the support plate 3 as shown in
It is also conceivable to design the recesses 37 as slots and the hook elements 53a, 53b in such a way that they encompass an angle of more than 90°.
In the embodiment variant shown here, as shown in
The counter strips 54a, 54b are positioned, as shown for example in
The recesses 37 at the rear edge 36 of the support plate 3 are preferably dimensioned in width so that they correspond to the width of the hook elements 53a, 53b and thus also cause a positioning of the support plate 3 perpendicular to the translational movement of the storage shelf 4.
In addition, as shown in
The stops 55a, 55b are, as shown in
As shown in
The support plate 3 is then pivoted downwards onto the base plate 2 by a pivoting movement. The rear edge 36 of the support plate 3 is embraced by the hook elements 53a, 53b, which prevents the support plate 3 from moving relative to the base plate 2 in the direction of the translational movement of the storage shelf 4 relative to the support plate 3. The counter strips 54a, 54b are located in the recess 39 recessed in the underside of the support plate 3, as shown in
As further shown in
In the embodiment variant shown in
Such a tilting protection element 7 is also arranged on the support plate 3 and shaped in such a way that it engages over an upper edge 48 of the storage shelf 4.
The tilting protection element 7 serves to prevent a tilting movement of the storage shelf 4 around a tilting axis parallel to the shelf surface 41 of the storage shelf 4. Such a tilting movement can occur, in particular, when loads are distributed unevenly on shelf surface 41 of storage shelf 4.
The tilting protection element 7 is preferably designed as a C-shaped catch hook, wherein a section 73 of the tilting protection element 7 protrudes from the rear edge of the support plate 3 and is bent upwards. A flat central section 72 is connected to this section 73, wherein the height extension of which is adapted to the vertical height of a wall surrounding the shelf surface 41 of the storage shelf 4, the upper edge 48 of which projects beyond a bent end 71 of the tilting protection element 7 adjoining the central section 72 and, in the event of a tilting movement, prevents the storage shelf 4 from tilting.
It is also conceivable to arrange retaining elements on the support plate 3 itself, in particular to form them around the base plate 2 and thus allow the support plate 3 to be fixed to the base plate 2.
The support plate 3 and the storage shelf 4 are fixed to each other for axial fixing by means of a fixing device 8.
As shown in
In order to enable a low-friction displacement movement, a washer 82 and a sliding ring 83 are placed on screw 81, which is in contact with the underside of the support plate 3 facing the base plate 2 in the area of slot 35.
For axial fixing with the storage shelf 4, a mounting receptacle 47 is inserted in the shelf surface 41 of the storage shelf 4, which is covered by a cap 84.
The underside of this cap 84 facing screw 81 is provided with a screw hole with an internal thread into which screw 81 can be screwed, thus holding the cap 84 axially in its mounting position.
The base plate 2 can be designed as a glass plate. It is also possible to design a base plate 2 as a wooden plate or a plate made of plastic or metal. The support plate 3 and the storage shelf 4 are preferably made of plastic or glass.
It is particularly advantageous that, for example, in the case of a household appliance designed as a refrigerating device, such as in particular a refrigerator or freezer, an already existing base plate 2, for example in the form of a glass plate, can be used to stabilize and retrofit the support plate and the storage shelf to create a storage shelf base 1, which can be moved simultaneously by translation and rotation and is therefore particularly easy to load or unload.
