Description

The invention relates to a household refrigeration device component with a base unit and a trailer unit for attaching storage goods containers. The trailer unit is pivotally mounted on the base unit with a pivot bearing. Furthermore, the invention also relates to a household refrigeration appliance with at least one such household refrigeration appliance component.

Domestic refrigeration appliance components with a door racks as the base unit, on which a trailer unit is pivotally mounted, are known from the prior art. So in the context on the WO 2009/083357 A1 to refer. However, the designs there are very extensive in terms of their number of components as well as very complex in terms of their functionality. This results in complex operating concepts and the movements can jam and spread through the structures. In addition, a local trailer unit for attaching storage containers is relatively complex designed and designed only as a forward projecting elongated wire bracket, which are arranged at a relatively large distance to each other and thus allow only the inclusion of very specific storage containers. The placement of these trailer units is very limited. In addition, the configuration of the suspension units is alternatively also such that the procedure for loading is already very difficult, since, as shown there, bottles must be very complex first threaded in order to then be attached to it.

Other versions of such household refrigeration components are from the WO 2009/083400 A2 known, where there is a rigid attachment unit can not be pivoted, but can only be moved linearly upwards and downwards. In addition, the local design of the trailer unit is designed as a tub, so basically no Daran-attaching storage containers is possible, but only the insertion or setting in this tub.

It is an object of the present invention to provide a household refrigeration device component in which the trailer unit is reduced in component and easy to handle and attaching storage containers can be done easily and user friendly.

This object is achieved by a domestic refrigerator component and a household refrigerator according to the independent claims.

An independent aspect of the invention relates to a household refrigeration appliance component with a base unit and a trailer unit for attaching storage containers, which is arranged with a pivot bearing pivotally mounted on the base unit. The trailer unit has at least one trailer slot for attaching the storage goods container, wherein the trailer slot is formed variable in its slot width. By such a very advantageous embodiment, the attachment of different sized storage goods container is possible. Even deformable and flexible storage containers, which may then be very rejuvenated, can be easily accommodated in this suspension slot. The variability of the assembly of the trailer unit of storage containers is thereby significantly increased.

It is preferably provided that the slot width can be changed by at least one rotary clamp, wherein the rotary clamp determines the slot width depending on its rotational position. The rotary clamp is a rotatable or rotatable element which is arranged to be movable relative to the bottom leg. It is arranged sunk in an advantageous embodiment in a hollow region of the bottom leg at least partially. As a result, it is also positioned protected and arranged to save space. Such a rotary clamp is a particularly advantageous embodiment in order to be able to continuously change this slot width and to react individually and immediately to the respective geometries and configurations of a region of a storage goods container to be received in the suspension slot.

Preferably, the rotary clamp on a radial axis to the axis of bulge, which is designed as a clamping part. A very local and highly functional slot width change and holding effect on the storage goods container to be attached is made possible. A particularly stable mount is also permanently enabled and also suitable for heavier goods containers unrestricted.

It is preferably provided that the clamping part has a structuring on an outer side contacting the storage goods container to be held. The mechanical coupling and holding effect is further improved. An undesirable slipping or slipping out of the storage container is thereby avoided.

It is preferably provided that the rotary clamp is held by a spring element automatically in a clamping position. In particular, it is thus provided that in the unloaded state the Slot width is minimized when this rotary clamp is arranged in the clamping position.

Preferably, the rotary clamp is part of a bulkhead clamp.

In particular, at least two opposed rotation clamps are provided, which are correspondingly functional and can variably change a suspension slot in the slot width.

An assembly of a storage goods container takes place in such an embodiment in particular by the fact that the storage product container is introduced with a specific portion through the slot opening of the Anhängeschlitzes and is moved by an additional movement from bottom to top through the Anhängeschlitz, thereby at least one rotary clamp automatically from a Clamping position is moved to a release position. If a specific area of the storage container is then received in the suspension slot and the storage container is then pulled downwards or due to its weight force it moves independently downwards, the rotary clamp is automatically returned to the clamping position and the weight-bearing self-holding of the storage goods container in the suspension slot supported.

When removing the storage container from this suspension slot, this can then also be done again by a slight upward lifting of the storage container, whereby the rotary clamp is then moved again from the clamping position to the release position and in this release position then pulling out the storage container the appendage slot over the slot opening. The extraction is then carried out vertically or at a specific angle to the hole axis of the Anhängeschlitzes.

The trailer unit has, in particular, a U-shaped bracket, which is hinged to side legs of the U-shape and by means of the pivot bearing pivotally mounted on the base unit and which has a side leg connecting the bottom leg of the U-shape. The bracket is pivotally mounted directly on a wall of the base unit. Such a configuration achieves a component-reduced and highly functional design without separate intermediate elements. Various additional components and further deflections or the like are not required. The handling of the trailer unit and thus the pivoting of the trailer unit is thus made easy and user-friendly. In addition, a particularly continuous and thus jerk-free and jam-free pivoting movement of the trailer unit is possible.

It is preferably provided that the bottom leg of the bracket has at least one Anhängeschlitz for attaching the storage container, which is formed variable in its slot width.

In particular, the bracket is formed integrally with respect to its U-shape and thus to this basic geometry. This also minimizes the number of components needed to design this basic shape. In addition, a very stable bracket is then created by this configuration, which also allows correspondingly large carrying forces. This bracket is therefore very stable in itself and stiff, so that no undesirable twisting occur both in the pivoting movement and in the assembly and removal of storage goods containers.

In particular, the hitch unit only has a single U-shaped bracket. A component-reduced design is thereby achieved as well as allows in a simple and robust functional concept. A jam-free and splay-free movement is thereby made possible.

In an advantageous embodiment, it is provided that the side legs with ends which are remote from the bottom leg, are arranged pivotably directly on the base unit. As a result, a particularly advantageous concept for easy and continuous pivoting is made possible, since due to the geometry of this bracket and the specific articulation points also corresponding leverage effects occur that allow a user-friendly and smooth movement of this bracket. In addition, it is then also achieved by this configuration, that in the swung-out state and thus in a position of use of the bottom leg maximally spaced from the wall of the base unit, on which the bracket is pivotally mounted, is spaced. The accessibility to attachment points of the trailer unit and thus the handling for loading the trailer unit with storage containers or for removing or suspending storage containers from the trailer unit is thus very easy and user-friendly.

It is preferably provided that at least one laterally projecting pivot pin is formed integrally at the ends of these side limbs. Characterized a component of the pivot bearing is provided on the bow side and arranged mechanically stable. By the one-piece design of this at least one pivot pin on at least one end of a side leg also reduces the number of separate components of the trailer unit. By such a laterally projecting pivot pin and a very simple, yet highly functional part is created, which still allows a reliable mechanical connection and particularly low-wear design of the pivot bearing. In particular, it is provided that in each case two protruding on opposite sides of this side leg pivot pin are formed at one end of a side leg, which protrude in opposite directions from these pages. This allows a further improved storage of the bracket on the wall of the base unit are made possible and a particularly smooth and low-distortion pivoting of the bracket. Especially at the coupling point of the pivot bearing between the bracket and the wall of the base unit thus a 2-point bearing is formed, whereby the pivoting movement takes place particularly evenly and in the desired predetermined path, even if relatively asymmetrical storage goods container are attached to the trailer unit and thus only on one side of a corresponding Gewichtsbeaufschlagung is given.

It is preferably provided that the trailer unit is pivotable between a storage position and a use position. A stowage is given by the fact that the bracket is positionally arranged on the wall of the base unit that he needs as little space and is virtually stowed in this regard. In this staging is provided in particular that a fitting of the bracket with storage containers is not possible. In contrast, the position of use is that position in which then a loading of storage goods containers is made possible. In the stowed position, the hitch unit is at least partially sunk in a receptacle of the base unit, in particular in a receptacle which is formed in the wall of the base unit. This allows a particularly space-saving positioning of the trailer unit in the stowed position. She is thereby arranged tidy. On the other hand, a certain protective position is achieved by such an at least partially recessed arrangement, in which the trailer unit can not be damaged, for example by abutment with other storage goods or the like.

In an advantageous embodiment, it is provided that the trailer unit is pivotable between a stowage position and a use position, wherein in the use position, a trailer slot for attaching the storage container, which is formed in the bottom leg of the bracket, is accessible from the front. As a suspension slot such a receptacle is defined, which is not completely closed in the direction of rotation about a slot axis. A suspension slot thus has a slot opening through which objects can be inserted into the slot. By such a configuration, a particularly simple assembly and thus a simple attachment of a storage product container is made possible on the trailer unit. Also, the removal and thus hanging a storage container is thus very simple. Since just a front open accessibility of the Anhängeschlitzes is provided, the slot opening is thus almost always facing the user and he can perform by simply introducing and introducing the storage container through the slot opening the introduction into the suspension slot. Complex handling procedures for introducing a storage goods container to the trailer unit are thereby avoided.

It is preferably provided that at least one spring element is formed, with which the hitch unit can be automatically transferred from a use position to a stowed position. This means that at least the use position is biased by a spring force of the spring element and then, when the use position is no longer needed, carried out by this biasing force of the spring element, an automatic return of the bracket in the stowed position. Preferably, this spring element is designed so that when fitted with a storage container with a possible slightly predetermined weight threshold already this biasing force is exceeded, so that in the assembled state of the trailer unit with a storage container this automatic return of the bracket is prevented from the use position in the stowed position.

In a further advantageous embodiment can be provided that the use position is locked. In particular, provision is made for it to be possible to fix a position of use of the attachment unit provided with a locking device of the household refrigerating appliance component for use with a storage goods container. An unwanted pivoting or folding away the bracket from the position of use is thereby avoided. It is thus also an advantageous placement and removal of storage containers made possible by this bracket, since this position of use is then fixed in position accordingly. Another advantage of this embodiment is the fact that even when a spring element is provided, with which the return of the bracket is automatically carried out from a use position in the stowed position, this is blocked. An undesirable automatic return of this bracket in the stowed position is thus also avoided by the locking unit.

It can be provided that the locking unit can be actuated manually by a user. The actuation can be done by a corresponding control element as an example.

In an advantageous embodiment it can be provided that the locking unit is a push-push device. This makes it possible, when the bracket is in the use position, by a pushing movement in a pivoting direction about the pivot axis, which is opposite to the pivoting direction when the use position pivots in the stowed position to release this locked position. If this loosening then takes place, the automatic pivoting back of the bracket by the biasing force of the spring element from the use position can be done in the stowed position.

Another aspect of the invention relates to a household refrigeration appliance with at least one such household refrigeration appliance component.

The household refrigerator may be, for example, a refrigerator or a freezer or a combined refrigerated freezer, which is designed for storing and preserving food.

The household refrigeration appliance component can then have as a base unit a door rack or a door or a shelf or a boundary wall of a receiving space. In particular, the wall of the base unit on which the trailer unit is pivotally mounted, a bottom of this door compartment. In particular, the trailer unit is pivotally mounted on an outer side or underside of the floor.

In 1 is a simplified illustration of an embodiment of a household refrigerator 1 shown. The household refrigerator 1 has a housing 2 in which at least one recording room 3 is designed for food. The recording room 3 can be a cooling compartment. However, it can also be a freezer. The household refrigerator 1 may also be formed with at least two different and separate receiving spaces.

Furthermore, the household refrigerating appliance 1 a door 4 on, which is pivotable on the housing 2 is arranged and to close the receiving space 3 is trained. An example is in the recording room 3 a shelf 5 arranged. The shelf 5 may be an example of a base unit of a household refrigerator component.

Likewise, the door can 4 an exemplary embodiment of a base unit of a household refrigerator component.

In the illustrated embodiment are on the door 4 , in number, position and geometry only by way of example, household appliances components 6 . 7 shown. A door rack is another example of a base unit of a household refrigerator component.

In the embodiment, the door racks is designed to be used as a base unit 8th is designed to hold food and is designed trough-like or trough-like and here is a box-like container. In addition to this base unit 8th indicates the household refrigerator component 6 a trailer unit 9 on that to the base unit 8th is formed separately, here in the embodiment with a pivot bearing 10 pivotable on the base unit 8th is arranged.

The trailer unit 9 is designed to attach at least one storage product container. In particular, a storage product container can be a dimensionally stable container. Preferably, however, a storage product container is elastically deformable in itself and generally not dimensionally stable. As an example of such storage goods container, a bag or a bag may be mentioned.

In 2 is a partial representation of 1 shown here, with the door here 4 is shown with consideration of the door compartment. In contrast to the representation in 2 Here is the trailer unit 9 not in a stowage position, but in a position of use.

The base unit 8th has a floor 11 on, at the bottom of the trailer unit 9 is arranged pivotally. The pivot bearing 10 has several connection points here. In particular, it is provided that the ground 11 on its underside a depression 12 in which the trailer unit 9 in the stowage, as in 1 is shown and also below 3 is explained, at least partially arranged sunk.

As in 2 it can be seen is the trailer unit 9 with a U-shaped bracket 13 trained or is through the bracket 13 educated. This U-shape is formed by two side legs 14 and 15 that with a bottom leg 16 connected to the U-shape.

In particular, this temple 13 integrally formed. As can be seen, is at one of the bottom leg 16 opposite end 14a of the side leg 14 and on one of the bottom legs 16 opposite end 15a of the side leg 15 a pivotable connection to the container or the base unit 8th educated. This is in the in 2 shown use position of the trailer 9 and thus the swung-out state of the bracket 13 a maximum distance of the bottom leg 16 from the ground 11 reached. The placement of the trailer unit 9 and accessibility to the trailer unit 9 are improved.

The pivot bearing 10 , Which has the two opposite pivot connections, has bracket-side pivot bearing elements and container-side pivot bearing elements. In the embodiment shown, the container-side pivot bearing elements receptacles for pivot pins on the bracket 13 are formed.

In this regard, in the illustration in 4 the coat hanger 13 preferably with two pivot pins 17 and 18 at the end 14a and pivot pins 19 and 20 at the end 15a shown. As can be seen, each of the two pivot pins 17 and 18 such as 19 and 20 each on opposite sides of the associated side legs 14 and 15 formed integrally and extend from these in each case in opposite directions. Every end 14a and 15a is thus with a 2-point storage in the pivot bearing receptacles of the base unit 8th coupled.

In 3 is the representation according to 2 shown, but with the trailer unit 9 and thus the temple 13 in the staging. In the stowage is an attachment of storage containers on the hanger 13 not possible.

As in the illustration according to 2 is shown, there is a storage container 21 shown. To such an attachment is provided that on the bottom leg 16 at least one hanging slot 22 , in particular several attachment slots 22 is formed, of which the clarity serving only some are provided with the corresponding reference numerals.

These suspension slots 22 are with here vertically oriented slot axes A trained, in the position of use of the bracket 13 in the embodiment shown here essentially in the height direction (y-direction) of the household refrigerating appliance 1 are oriented. These suspension slots 22 are formed so that they are in the direction of rotation about this slot axis A are not completely closed and thus a respective slot opening 23 exhibit. The slot opening 23 is in the embodiment shown here a trailer unit 9 oriented to the front and thus open in the depth direction (z-direction) to the front and exposed. An assembly of a suspension slot 22 with a storage container 21 can thus easily be done from the front. A specific area of the storage container 21 , here a bundled area 21a of the bag, then is over this slot opening 23 in the hanging slot 22 insertable. The attachment slot 22 is designed so that the storage goods container attached thereto 21 is held independently and axially does not slip down or fall out and not on the slot opening 23 slips sideways or falls out.

This is how in 4 in the top view of the temple 13 can be seen, a holding unit provided. This holding unit 24 has in the embodiment two rotary clamps 25 and 26 on, rotatably mounted on the bracket 13 , especially the bottom leg 16 are formed. You are doing in each hollow areas of the bottom leg 16 arranged rotatably mounted. When displayed in 4 are rotation axes B and C of rotary clamps 25 and 26 oriented perpendicular to the plane of the figure. These rotary axes B and C are thus also in particular parallel to the slot axis A ,

The respective paired in the preferred embodiment provided for rotation clamps 25 and 26 clamp the storage container 21 ,

In particular, it is also provided that a trailer slot 22 with a variable slot width a is trained. The slot width a is by twisting the rotation clamps 25 and 26 automatically continuously changeable. The rotational movement of the rotary clamps 25 and 26 is thereby by the removal or insertion of the storage goods container 21 in the hanging slot 22 completed.

In 5 are exemplary two rotary clamps 25 and 26 shown in a clamping position. As can be seen here, the rotation clamp 25 one to the axis of rotation B radial bulge on, as a clamping part 25a is trained. On an outside 25b this clamping part 25a is a structuring 27 trained, which may be teeth, for example. Also a certain roughened state of this outside 25b can be provided as structuring. The structuring 27 is in particular an embodiment to the gripping and mechanical contacting of the storage product container 21 , especially in the field 21a , to improve and to increase the frictional resistance, to prevent unwanted slipping out of the storage container 21 to avoid from the clamping position.

Accordingly, here also advantageously the rotary clamp 26 formed, which is also a clamping part 26a on an outside 26b has, in particular also a structuring 28 is trained.

In 6 is a release position or release position of the rotary clamps 25 and 26 shown. They are in this embodiment with their clamping parts 25a and 26a Turned away from each other, so that in this state in the holding area of the Anhängeschlitzes 22 formed slot width a here is larger than in the clamping position according to 5 ,

Holding and contacting the storage container 21 is with these structurings 27 and 28 provided and thus with the clamping parts 25a and 26a ,

In particular, it is provided that the rotation clamps 25 and 26 are held by a respective spring element in the clamping position as a basic position. Will now be equipped with a storage container 21 provided and this via a slot opening 23 in a trailer slot 22 introduced and in particular pulled at the same time then in particular from the bottom up, this biased clamping position is automatically opened and in the release position according to 6 brought. Is then the hinged storage position of the storage container 21 achieved and then by manually pulling down on the storage product container 21 and / or by the weight of the storage goods container 21 alone carried out such an operation, then automatically turn the clamping position according to 5 reached and then the storage goods container as shown in 2 held.

To release then the storage product container 21 be pulled back slightly upwards from said position, which in turn then the release position according to 6 is reached and then over the slot opening 23 from the suspension slot 22 led out.

In an advantageous embodiment, it is provided that in addition a further spring element 29 and 30 which is in 2 is indicated only by the reference numeral and is not explicitly recognized, the bracket 13 is automatically transferred from the use position in the stowed position. In the use position then this spring element is biased so that this automatic return movement is possible.

In order to avoid a continuous return movement through this prestressed spring element, preferably a locking unit 31 be provided, for example, at both pivot bearing points or at only one pivot bearing point of the pivot bearing 10 can be trained. With this locking unit 31 can also lock the use position against the spring force of the preferably existing spring element, as it was called. Preferably, this locking unit 31 for example, be a push-push device.
