Description

The present invention relates to a household appliance, in particular a refrigerator or freezer, or furniture with at least one storage space or a storage area in which or on the at least one carrier plate with a storage area and a shelf movable in rotation and translation on the storage area of the carrier plate is arranged, according to the Preamble of claim 1.

In household appliances such as refrigerators or freezers or in cupboard furniture, areas that are difficult to reach are often present in a storage space or on a storage area. The accessibility of objects placed in the rear area of a storage space or a storage area is often only possible to a very limited extent. In particular, storage spaces that are arranged in a user-unfriendly manner, for example above head height or below knee height, are difficult to reach.

Unscrewing or swiveling out a turntable that is mounted in the storage space or on the storage area appears to eliminate the above-mentioned Disadvantages sensible.

In the case of household appliances or furniture known from the prior art, predominantly sequential rotary and translational movements are combined with one another, these two types of movement usually occurring separately from one another or one after the other. Such solutions are technically very complex. The rotational movement is often only possible to a limited extent, in particular only by 90 °, which further complicates the accessibility of the elements stored in such storage spaces or on such storage areas. In addition, numerous solutions have weak points in the absorption of supporting forces and stability as well as large construction heights.

DE 9300364 U1 discloses a pull-out device for cabinet pull-outs with a rotatory and translational movable shelf.

The object of the present invention is to provide an improved household appliance, in particular a refrigerator or freezer, or furniture with at least one storage space or at least one storage area, in or on the at least one carrier plate with a storage area and one on the storage area Support plate is arranged rotatably and translationally movable shelf, with which the above disadvantages are eliminated.

This task is achieved by a household appliance, in particular a refrigerator or freezer, or furniture with at least one storage space or at least one storage area in which or on the at least one carrier plate with a storage area and a shelf that can be moved in rotation and translation on the storage area of the carrier plate, solved with the features of claim 1.

The household appliance according to the invention, in particular a refrigerator or freezer, or furniture with at least one storage space, in which at least one carrier plate is arranged with a storage area and a shelf that can be moved in rotation and translation on the storage area of the carrier plate, the shelf having a flat storage area that is plane-parallel is aligned with the bearing area of the carrier element, the tray being rotatable relative to the carrier plate in a first direction of rotation and displaceable in a predetermined direction, is characterized in that facing bearing surfaces of the bearing areas have respective closed, circumferential running grooves in which rolling elements are guided .

The grooves are shaped in such a way that when a force is exerted on the shelf in a direction of the shelf defined in the plane of the storage area in a positively guided, simultaneous rotary and translational movement from a basic position via an intermediate position in which the shelf is relative to the carrier plate in a first direction of rotation rotated and displaced in a predetermined direction, the object being rotatable relative to the carrier plate after the movement into the intermediate position further in one of two possible opposite directions of rotation and displaceable against the predetermined direction and resumes the basic position when rotated by 180 °. An advantageous intermediate position is approximately 90 °. The object can be rotated through any angle relative to the carrier plate.

The positively driven, simultaneous rotary and translational movement between the tray and the carrier plate is preferably in an area between the basic position and shortly before reaching the intermediate position, which is advantageously at 90 °, in each of the two possible opposing positions Directions of rotation. In the area of the 90 ° position of the shelf relative to the carrier plate, only a rotary movement can be present.

Due to the bearing surfaces of the bearing areas, which are equipped with the circumferential running grooves and which allow an at least partially simultaneous rotary and translational movement, the shelf can be moved in a simple manner on the carrier plate.

The simple construction of this arrangement by making the closed circumferential running grooves in the underside of the shelf and in the top of the support plate reduces manufacturing costs, increases the robustness of the device and is user-friendly to operate. The accessibility of the elements arranged in the rear area of the storage space or the storage area is thus improved.

According to an advantageous embodiment variant of the invention, two closed, circumferential running grooves are made in one of the bearing areas and precisely one closed, circumferential running groove is made in the other of the bearing areas.

Particularly preferably, each of the three running grooves has the same profile, with one of the two running grooves being mirrored to the running groove and the other of the two running grooves being rotated by 180 ° and shifted by a predetermined amount relative to one of the two running grooves.

With such a groove contour, an easy-to-use simultaneous rotary and translational movement of the shelf relative to the carrier plate is made possible.

According to a preferred embodiment variant, the rolling elements are designed as balls, which enables a low-friction movement of the tray relative to the carrier plate.

In order to allow the bearing load on the individual rolling elements while maintaining a simple running groove design, four such rolling elements are preferably guided in the running grooves.

According to a further preferred embodiment variant, the rolling elements are held in a rolling element cage, preferably secured against loss. This is the Forced guidance of the rolling elements when moving in the running grooves improved again.

According to an embodiment variant of the invention, the storage areas of the shelf or the carrier plate are formed in one piece with the carrier plate or the shelf.

In an alternative embodiment, at least one of the storage areas is designed as a separate element which can be inserted into a correspondingly shaped receptacle in the carrier plate or the tray or which can be attached to the carrier plate or the tray by connecting means.

According to a further preferred embodiment variant, a guide, for example a slot extending in the translational direction of movement, is arranged in one of the bearing areas and a guide or holding element is arranged on or in the other bearing area. For example, a bore is made in the other bearing area, in which a guide and retaining pin or bolt is received. This also contributes to the further improvement of the forced guidance. In addition, the tray and the carrier plate can be held axially against one another in a simple manner.

According to a further preferred embodiment variant, the closed circumferential running grooves are each made around the center point of the storage area of the shelf and the storage area of the carrier plate up to the front edge of the carrier plate in the direction of the translational movement of the shelf.

This enables a large support surface. Furthermore, this results in a particularly favorable load absorption, which also increases the stability of the entire device.

For improved positioning of the shelf in the basic position, the closed circumferential running grooves preferably have several locking points for the rolling elements in the basic position, which is reached after each rotation of the shelf by 180 °.

According to a further advantageous embodiment variant, the tray is in a first direction of rotation and in an opposite direction relative to the carrier plate second direction of rotation rotatable, which further simplifies the operability of the device.

A further simplification of the operability of the device is achieved in that the tray can be rotated by any angle relative to the carrier plate in a first direction of rotation and in an opposite second direction of rotation.

According to a preferred embodiment variant, the carrier plate is mounted horizontally in the storage space. However, it is also conceivable to mount the carrier plate in a hanging or vertical position.

In the following description of the figures, terms such as above, below, left, right, front, rear, etc. relate exclusively to the exemplary representation and position of the carrier plate, the shelf, the bearing area, the rolling elements, the running groove and the like selected in the respective figures. These terms are not to be understood as restrictive, i.e. these references can change as a result of different working positions or the mirror-symmetrical design or the like.

In the in Figure 7 The embodiment shown, a conventional glass shelf in a storage space 13 of a refrigerator 1 is replaced by a carrier plate 3 with a storage area 5 and an object in the form of a shelf 2 with a storage area 4 that can be moved in rotation and translation on the storage area 5 of the carrier plate 3. The refrigerator 1 consists of a body 11 to which a door 12 is pivotably articulated and closes the storage space 13.

Accordingly, in the in Figure 8 The embodiment shown, a common shelf in a storage space 24 of a cabinet 20 is replaced by a carrier plate 3 with a storage area 5 and an object in the form of a shelf 2 with a storage area 4 that can be moved in rotation and translation on the storage area 5 of the carrier plate 3. The cabinet 20 consists of a body 21 to which two doors 22, 23 are pivotably articulated and close the storage space 14.

The rotationally and translationally mounted shelf 2, here designed as a plate-shaped shelf with a flat storage area, is available as a storage area for the refrigerated goods to be stored in the case of use in a refrigerator 1 and has the shape of a circle in which two opposing circular segments of the same size are removed are. This creates an optimal storage space for the refrigerated goods. Furthermore, there is a grip and holding element 200 on the shelf 2 for operating the shelf 2 and for securing the stored items to be cooled.

The facing bearing surfaces of these bearing areas 4, 5 each have closed, circumferential running grooves 41, 51, in which rolling elements 6 are guided. The rolling elements 6 are preferably designed as balls.

The running grooves 41, 51 are shaped in such a way that when a force is exerted on the shelf 2 in a direction A defined in the plane of the storage area, the shelf 2 moves in a forced, simultaneous rotary and translational movement from a basic position via an intermediate position in which the shelf 2 is rotated relative to the carrier plate 3 in a first direction of rotation R ₁ and shifted in a predetermined direction A.

In a preferred intermediate position, the tray 2 is rotated by approx. 90 ° with respect to the basic position, the displacement reaching its maximum in the predetermined direction.

The shelf 2 can be moved back into the basic position by continuing to rotate it in the direction of rotation R1, in this case the shelf 2 is rotated by a total of 180 ° relative to the carrier plate 3 and shifted back to the basic position against the predetermined direction A.

Alternatively, the shelf 2 can be moved back to the basic position by being turned back in the opposite direction to the direction of rotation R1 in the direction of rotation R2. The direction A here denotes the direction out of the storage space 13, 24 of the refrigerator 1 or of the cabinet 20.

As in the Figures 4 to 6 As shown, two closed, circumferential running grooves 44, 45 are made in the storage area 4 of the tray 2. In the bearing area 5 of the carrier plate 3, exactly one closed, circumferential running groove 51 is made.

The reverse arrangement is also conceivable, in which two running grooves are made in the bearing area 5 of the carrier plate 3 and one running groove in the bearing area 4 of the tray 2.

The three running grooves 44, 45, 51 are preferably of the same shape. Here is how in the Figures 4 and 5 Clearly visible, one of the two running grooves 44 of the bearing area 4 of the shelf is mirrored to the running groove 51. The other of the two running grooves 45 is rotated by 180 ° relative to the running groove 44 and shifted by the amount of the translational movement.

The closed circumferential running grooves 44, 45, 51 in the tray 2 and the stationary carrier plate 3 cause the rolling elements 3 to be guided during the Pressing the tray 2, rotating and pulling out the tray 2 at the same time.

As in the Figures 2, 3 , 4th and 5 Also shown, the rolling elements 6, which are designed here as balls, are held in a rolling element cage 7. The rolling elements 6 are preferably held in the rolling element cage 7 in such a way that they cannot be lost. It is also conceivable to guide the rolling elements only in openings in the rolling element cage 7 provided for this purpose.

For the axial fixation of the carrier plate 3 with the tray 2, a guide in the form of a slot 8, which extends in the translational direction of movement A, is introduced in the bearing area 5 of the carrier plate 3. A bore 46 is made centrally in the storage area 4 of the shelf 2, so that the shelf 2 is fixed coaxially and concentrically. A guide and holding element in the form of a pin 9 passes through the slot 8 and the bore 46 and thus ensures an axial fixation of the tray 2 on the carrier plate 3. If the carrier plate 3 and the tray 2 resting on it is mounted horizontally, the axial Backup can also be omitted. There can also be more than one axial securing device or a different axial securing device.

While the in Figure 4 The embodiment variant shown, the storage areas 4, 5 are integrally formed with the shelf 2 or the carrier plate 3, in which the grooves 44, 45, 51 are introduced directly into the underside of the shelf 2 or the top of the carrier plate 3, are the storage areas 4, 5 at the in Figure 5 The embodiment variant shown is designed as separate elements in the form of bearing plates 42, 52 which can be fastened to the underside of the shelf 2 or to the upper side of the carrier plate 3.

For this purpose, respective fastening receptacles 54, 47 are formed on the side edges of the bearing plate 42, 52, into which screws can be inserted, with which the bearing plates 42, 52 can be fixed to the tray 2 or the carrier plate 3.

In order to keep the load on the rolling elements 6 as low as possible and at the same time enable a simply constructed running groove, four such rolling elements 6 designed as balls are guided in the running grooves 444, 45, 51 in the embodiment variant shown here. Alternatively, there can also be two or eight rolling elements.

As in the Figures 4 , 5 and 6th shown, the closed circumferential running grooves 44, 45, 51 are introduced over the center point of the storage area 4 of the shelf and the storage area 5 of the support plate 3 up to the front edge of the support plate 3 in the direction A of the translational movement of the shelf 2.

In order to allow the shelf 2 to easily snap into the basic position, in which the shelf 2 does not protrude beyond a front side edge of the carrier plate 3, the closed circumferential running grooves 44, 45, 51 have several locking points 43, 53 for the rolling elements 6 in the basic position on. This basic position is reached after each rotation of the shelf 2 by 180 °.

In a further embodiment, selected intermediate positions can also have locking points, for example when the tray 2 is rotated relative to the carrier plate 3 by 90 °.

The locking points 43, 53 are characterized by the fact that a slightly increased expenditure of force is required to move out of these positions. This increased expenditure of force can be achieved, for example, by appropriately designing the grooves 44, 45, 51 with depressions or raised knobs or the like. Other elements for influencing the force, such as magnets, are also conceivable. With the shape of the grooves 44, 45, 51 shown here, it is possible for the tray 2 to rotate relative to the carrier plate 3 in one direction of rotation R ₁ and also in an opposite direction of rotation R. _{2 is} rotatable.

In addition, with this shape of the running grooves 44, 45, 51, the tray 2 can be rotated through any angle. It is thus possible to rotate the tray 2 by 180 ° to the carrier plate 3 in the first direction of rotation R ₁ with a first rotary movement and to rotate the tray 2 again in the same first direction of rotation R ₁ or, alternatively, in the opposite second direction of rotation when the button is subsequently operated Rotation direction R ₂ to rotate.

During use, by pulling on the grip and holding element 200, which causes the introduction of a transverse force, the tray 2 is set in motion by moving the rolling elements 6 out of the locking points 43, 53 in a clockwise or counter-clockwise direction. At the same time, there is forced control in addition to the Rotational movement of the tray 2, the translational movement is carried out forwards to its end point. With further rotation, the translation towards the rear is resumed between the 90 ° position and 180 ° position and, after a 180 ° rotation, a basic position is reached in the locking points 43, 53. The basic position is reached after another 180 ° turn. In the entire cycle of the rotary and translational movement of the shelf 2 by 360 °, it is possible to load and access the refrigerated goods.

Due to the geometric design of the closed grooves in the underside of the shelf 2 and in the top of the carrier plate 3 around the respective center point of the shelf 2 and the carrier plate 3 with the greatest possible distance from the respective center point, if possible up to the front edge of the shelf 2 and the Carrier plate 3, a large support surface is achieved, the supporting forces are well absorbed and the stability of the entire device is increased.

The forced operation increases the usability, the overall height is reduced by the compact design and incorrect operation is prevented. The unlimited angle of movement - clockwise and anti-clockwise rotation - enables any sequence without a preferred direction of 360 °. The simple structure reduces the manufacturing costs and increases the robustness of the guide device.

In Fig. 7 and Fig. 8 it can be seen that the shelf 2 does not protrude in the intermediate position of approximately 90 ° in direction A beyond the rear edge of the carrier plate 3.

In addition to the in Figure 8 It is also conceivable to mount such a rotationally and translationally movable shelf 2 in a chest of drawers or lowboard.

It is also conceivable for the hanging textiles to be hung parallel to the front in a piece of furniture designed as a wardrobe or cloakroom. The device then allows easy access to those hanging behind.

Use in the medical field or in the sales area (cooling and freezing equipment) in department stores is also conceivable. There have to be many small ones Packaging units are organized. The ability to access a front and a rear area of the tray 2, which can be moved in a rotational and translational manner, increases the clarity. In addition, it makes access easier if access is possible from the front and back.

The use of a rotatory and translationally movable shelf 2 of a worktop is also conceivable. The shelf 2 enables household appliances such as coffee machines, toasters or the like to be moved forward only when required in niches (for example, sloping ceilings).

In general, both a tray and a box are conceivable. A tray with organizational elements for horizontal and / or vertical organization is also conceivable.

The guide can be standing, hanging or standing and hanging.
