Description

Domestic appliance, in particular refrigerator or freezer, or furniture with at least one shelf

The present invention relates to a household appliance, in particular refrigerator or freezer, or furniture with at least one storage space or a

Staufläche by or on the at least one support plate with a

Storage area and a rotatably and translationally movable on the storage area of the support plate tray is arranged, according to the preamble of claim 1.

In household appliances such as refrigerators or freezers or cabinet furniture often hard to reach areas in a storage space or on a storage area are available. The accessibility of filed in particular in the rear of a storage space or a storage area

Items are often very limited. Especially

User unfriendly arranged storage spaces, for example, above the head height of a person or below the knee level are difficult to achieve.

Unscrewing or swinging out a turntable in the

Storage space or is mounted on the storage area, appears to eliminate this o.g. Disadvantages make sense.

In the household appliances or furniture known from the state of the art, predominantly sequential rotational and translatory movements are combined with one another, whereby these two types of movement as a rule take place separately or one after the other. Such solutions are technically very complex. The rotation is often only

restricted possible, in particular only by 90 °, which further complicates the accessibility of the stored in such storage spaces or on such storage areas elements. In addition, numerous solutions have weak points in the absorption of support forces and the stability as well as large heights on.

Object of the present invention is an improved household appliance, in particular refrigerator or freezer, or furniture with at least one storage space or at least one storage area, in or on the at least one support plate with a storage area and on the storage area of the Support plate rotatory and translationally movable tray is arranged to provide, with which the above-mentioned disadvantages are eliminated.

This object is achieved by a household appliance, in particular refrigeration or

Freezer, or furniture with at least one storage space or at least one storage area in which or on the at least one support plate with a storage area and a rotatably and translationally movable on the storage area of the support plate tray is arranged, with the features of

Claim 1 solved.

The household appliance according to the invention, in particular cooling or

Freezer, or furniture with at least a storage space in which

at least one carrier plate with a storage area and one on the

Storage area of the support plate is arranged rotatory and translationally movable tray, wherein the tray has a flat storage area which is aligned plane-parallel to the storage area of the support member, wherein the tray is rotatable relative to the carrier plate in a first direction of rotation and displaceable in a predetermined direction is characterized characterized in that mutually facing bearing surfaces of the bearing areas respective

have closed, circumferential grooves, in which rolling elements are guided.

The grooves are shaped such that when force is applied to the tray in a defined in the plane of the storage area direction of the tray in a positively guided, simultaneous rotational and translational movement of a base position via an intermediate position, wherein the tray relative to the support plate in a first rotational direction is rotated and displaced in a predetermined direction, wherein the object relative to the support plate after moving into the intermediate position further in one of two possible opposite directions of rotation rotatable and against the predetermined direction is displaceable and at a rotation of 180 ° again the

Basic position. An advantageous intermediate position is approximately at 90 °. The object is rotatable relative to the support plate by any angle.

Preferably, the positively driven, simultaneous rotational and translational movement between the tray and carrier plate 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 opposite Rotation. In the region of the 90 ° position of the tray relative to the carrier plate may also be present only a rotational movement.

By equipped with the circumferential grooves bearing surfaces of the bearing areas, which allow an at least partially simultaneous rotational and translational movement, the tray is movable in a simple manner on the support plate.

The simple structure of this arrangement by introducing the

closed circumferential grooves in the bottom of the tray and in the top of the carrier plate reduces the cost, increases the

Robustness of the device and is user friendly to use. Thus, the accessibility of the arranged in the rear of the storage space or the storage area elements is improved.

According to an advantageous embodiment of the invention, two closed, circumferential grooves are introduced in the one of the bearing areas and exactly introduced in the other of the bearing areas a closed, circumferential track groove.

In this case, particularly preferably each of the three running grooves the same

Course contour on, wherein one of the two grooves mirrored to the groove and the other of the two grooves is rotated by 180 ° and displaced by a predetermined amount to one of the two grooves is formed.

With such a raceway contour, an easy-to-use simultaneous rotational and translational movement of the tray relative to the carrier plate is made possible. The rolling elements are designed according to a preferred embodiment as balls, which is a low-friction relative movement of the tray to

Support plate allows.

In order to allow the support load on the individual rolling elements while maintaining a simple Laufrillengestaltung, preferably four such rolling elements are guided in the grooves.

The rolling elements are held in accordance with a further preferred embodiment in a Wälzkörperkäfig, preferably secured against loss. This is the result Forced guidance of the rolling elements during the movement in the grooves again improved.

The storage areas of the shelf or the support plate are according to a

Embodiment variant of the invention integrally formed with the support plate or the tray.

In an alternative embodiment, at least one of the bearing areas is formed as a separate element, which in a correspondingly shaped

Recording in the support plate or the tray is used or which can be attached by connecting means to the support plate or the tray.

According to a further preferred embodiment variant, in one of the bearing areas a guide, for example a slot extending in the translatory movement direction, and on or in the other

Storage area arranged a guiding or holding element. For example, a bore is introduced 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 operation. In addition, the tray and the carrier plate can thereby be held axially together in a simple manner.

The closed circumferential grooves are according to a further preferred embodiment, each about the center of the

Storage area of the shelf and the storage area of the support plate to a front in the direction of the translational movement of the shelf edge of the support plate introduced.

This allows a large contact surface. Furthermore, this results in a particularly favorable load bearing, which also increases the stability of the entire device.

For improved positioning of the tray in the home position, the closed circumferential grooves preferably have a plurality of locking points for the rolling elements in the basic position, which is achieved in each case after a rotation of the tray of 180 °.

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

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

The support plate is mounted according to a preferred embodiment lying in the storage space. It is also conceivable to mount the support plate hanging or standing vertically.

Hereinafter, a preferred embodiment of the invention will be explained in more detail with reference to the accompanying drawings. Show it:

Fig. 8 is a perspective view of a cabinet cabinet with a plurality of shelves designed as objects. In the following description of the figures, terms such as above, below, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the carrier plate, the tray, the storage area, the rolling bodies, the track groove and the like chosen in the respective figures.

These terms are not meant to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change. In the embodiment shown in Figure 7, a common glass bottom in a storage space 1 3 of a refrigerator 1 by a

Support plate 3 with a storage area 5 and a rotatably and translationally movable on the storage area 5 of the support plate 3 object in the form of a shelf 2 with a storage area 4 replaced. The refrigerator 1 consists of a body 1 1 to which a door 1 2 is pivotally hinged and the storage space 1 3 closes.

Accordingly, in the embodiment shown in Figure 8 is a common shelf in a storage space 24 of a cabinet furniture 20 by a support plate 3 with a storage area 5 and a on the

Storage area 5 of the support plate 3 rotatory and translationally movable object in the form of a shelf 2 with a storage area 4 replaced. The cabinet furniture 20 consists of a body 21 to which two doors 22, 23 are pivotally hinged and close the storage space 14.

The rotatory and translationally mounted tray 2, designed here as a plate-shaped tray with a flat storage area, is available as a storage area for the refrigerated goods to be stored in a refrigerator 1 in the case of application and has the shape of a circle, in which two opposite equal-sized circle segments removed are. This creates an optimal

Storage space for the refrigerated goods. Furthermore, located on the tray 2, a handle and holding element 200 for the operation of the tray 2 and to secure the stored refrigerated goods. The mutually facing bearing surfaces of these bearing areas 4, 5 each have closed, circumferential grooves 41, 51, in which rolling elements 6 are guided. The rolling elements 6 are preferably formed as balls. The grooves 41, 51 are shaped so that when force is applied to the tray 2 in a direction defined in the plane of the storage area A, the tray 2 in a positively guided, simultaneous rotational and translational movement of a base position via an intermediate position in which the tray. 2 is rotated relative to the support plate 3 in a first direction of rotation R-ι and moved in a predetermined direction A.

In a preferred intermediate position, the tray 2 is rotated by about 90 ° relative to the home position, wherein the displacement reaches its maximum in the predetermined direction.

The tray 2 can be moved back to the home position by being further rotated in the direction of rotation R1, in this case the tray 2 is rotated relative to the support plate 3 by a total of 180 ° and moved back against the predetermined direction A back to the basic position.

Alternatively, the tray 2 can be moved back to the home 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 designates the direction out of the storage space 13, 24 of the refrigerator 1 or of the cupboard 20.

As shown in Figures 4 to 6, two closed, circumferential grooves 44, 45 are introduced in the storage area 4 of the tray 2. In the storage area 5 of the support plate 3 is exactly a closed, circumferential track 51 is introduced.

Also conceivable is the reverse arrangement, in which two grooves in the

Storage area 5 of the support plate 3 and a groove in the storage area 4 of the tray 2 are introduced.

The three raceways 44, 45, 51 are preferably of the same shape. It is, as clearly visible in Figures 4 and 5, one of the two grooves 44 of the

Storage area 4 of the tray to the track 51 mirrored. The other of the two grooves 45 is rotated by 180 ° to the groove 44 and formed displaced by the amount of translational movement.

The closed circumferential grooves 44, 45, 51 in the tray 2 and the stationary support plate 3 cause the positive guidance of the rolling elements 3 at Press Tray 2, simultaneously rotate and pull out Tray 2.

As further shown in FIGS. 2, 3, 4 and 5, the rolling bodies 6 embodied here as balls are held in a rolling element cage 7. The rolling elements 6 are preferably secured against loss in the Wälzkörperkäfig 7 held. It is also conceivable to guide the rolling elements only in openings provided for the Wälzkörperkäfigs 7. For axial fixation of the support plate 3 with the tray 2 is in the

Storage area 5 of the support plate 3 is in the translational

Moving direction A extending guide introduced in the form of a slot 8. In the storage area 4 of the tray 2, a bore 46 is centrally introduced, so that the tray 2 is fixed coaxially concentric. A guide and retaining 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

Support plate 3. Is the support plate 3 and the shelf 2 resting thereon mounted horizontally, the axial securing can also be omitted. There may also be more than one axial securing or a different type of axial securing.

While in the embodiment shown in Figure 4, the storage areas 4, 5 are integrally formed with the tray 2 and the support plate 3, in which the grooves 44, 45, 51 directly into the bottom de of the tray 2 and the top of the support plate. 3 are introduced in the embodiment variant shown in Figure 5 as separate elements in the form of bearing plates 42, 52 which are fastened to the underside of the tray 2 and at the top of the support plate 3. These are at side edges of the bearing plate 42, 52 respective

Fastening recesses 54, 47 integrally formed in the screws are used, with which the bearing plates 42, 52 on the tray 2 and the support plate 3 can be fixed. In order to keep the load on the rolling elements 6 as low as possible and at the same time to 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, two or eight

Rolling be present. As shown in Figures 4, 5 and 6, the closed circumferential grooves 44, 45, 51 over the center of the storage area 4 of the tray and the storage area 5 of the support plate 3 to a front in the direction A of the translational movement of the tray 2 edge the support plate 3 is introduced.

In order to allow the tray 2 in the basic position, in which the tray 2 does not protrude beyond a front side edge of the support plate 3, easily engage, have the closed circumferential grooves 44, 45, 51 more

Resting points 43, 53 for the rolling elements 6 in the basic position. These

Basic position is achieved in each case after a rotation of the tray 2 of 1 80 °. In a further refinement, selected intermediate positions may also have latching 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 for the movement of these positions out a little increased effort is required.

This increased force can be achieved for example by a corresponding shape design of the grooves 44, 45, 51 with recesses or raised nubs or the like. Also other elements to

Influencing the force, e.g. Magnets are conceivable. In the shape shown here of the grooves 44, 45, 51, it is possible that the tray 2 relative to the support plate 3 in a rotational direction Ri and also in one,

opposite direction of rotation R _{2 is} rotatable.

In addition, the tray 2 can be rotated at any angle in this shape of the grooves 44, 45, 51. So it is possible, the tray 2 at a first rotational movement by 180 ° to the support plate 3 in the first

Rotate direction of rotation R-ι and in a subsequent operation, the tray 2 again in the same first direction of rotation R-ι to rotate or alternatively to rotate in the opposite second direction of rotation R ₂ .

In use, by pulling on the handle and holding element 200, which causes the introduction of a transverse force, the tray 2 by moving out of the rolling elements 6 from the locking points 43, 53 right or left turn in

Movement set. It is forcibly controlled simultaneously with the Rotational movement of the tray 2, the translation movement forward to the end point executed. Upon further rotation between the 90 ° position and 1 80 ° position, the translation back to the back

taken and after a 1 80 ° rotation a basic position in the

Rast points 43, 53 reached. After another 1 80 ° turn, the home position is reached. Throughout the cycle of rotary and

translatory movement of the shelf 2 by 360 °, the loading of goods to be cooled and access to the goods to be cooled are possible. Due to the geometric design of the closed grooves in the bottom of the tray 2 and in the top of the support plate 3 to the respective center of the tray 2 and the support plate 3 with the largest possible distance from the respective center, preferably to the front edge of the tray 2 and the Support plate 3, a large contact surface can be achieved, the support forces well received and increases the stability of the entire device.

The forced operation increases the suitability for use, reduces the height due to the compact design and prevents incorrect operation. The unlimited movement angle - clockwise and anti-clockwise - allows any sequence without a preferred direction by 360 °. The simple construction reduces the manufacturing costs and increases the robustness of the

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

In addition to the embodiment of the cabinet furniture 20 shown in Figure 8, it is also conceivable to mount such a rotatory and translationally movable tray 2 in a dresser or lowboard.

It is also conceivable that in a designed as a wardrobe or wardrobe furniture, the hanging textiles are hung front parallel. The device then allows easy access to the rear hanging.

A use in the medical field or in the sales area (cooling and frost directions) in retail halls is conceivable. There must be many small ones Packaging units are organized. The ability to access a front and a rear portion of the rotatory and translatory movable tray 2 clarity is increased. In addition, it facilitates access when access is possible from the front and from behind.

It is also conceivable the use of a rotatory and translationally movable tray 2 a worktop. The shelf 2 allows here in niches (for example, sloping roof) home appliances such as coffee maker, toaster or the like can only be moved forward if necessary.

Generally versions are conceivable as a tray and as a box. Also, a tray with organizational elements for horizontal and / or vertical organization is conceivable.

The guidance can be done standing, hanging or standing and hanging.
