Description

The invention relates to a pull-out device for a household refrigerator. The extension device is designed for storing food on different levels. The extension device has for this purpose a first food storage unit, which is arranged on a first level. This first food storage unit is slidably mounted in an extension direction. The extension device has a second food storage unit separate therefrom, which is arranged on a second plane different from the first plane and is displaceably mounted in the extension direction. The extension device has a coupling device, with which the food storage units can be coupled in their movements and in the motion-coupled state together in the extension direction can be pulled out. Furthermore, the invention also relates to a household refrigerator with such a pull-out device.

Such pull-out devices are known from the prior art. For example, shows the US 2006/0218958 A1 a pull-out device, which is designed as a drawer and is provided for storing bottles at different levels. A lower platen for such bottles is firmly connected to a front wall of the drawer and extendable with this. A heightwise arranged above another plate for storing bottles is connected to a coupling device with this lower plate. In a pull-out in the extension direction, these trained on different levels plates are extended over different extension lengths, so that each positioned thereon bottles are accessible in both planes. The local coupling device is complex, however, so that coupling and decoupling is subject to complex processes, so that here a certain error rate can occur.

Furthermore, from the US 2016/0178274 A1 a pull-out device for a household refrigerator known. There are two bowls can be coupled together. A coupling device has a wedge displaceable in the height direction, which can couple with a stop depending on the pull-out position of the drawer. The wedge is connected to separate coil springs, through which the wedge is pressed down. The structure here is complex and component-intensive, so that the coupling and decoupling can be error-prone. In addition, the coil springs may wear over time and at least reduce their spring force, so that the movement functionality of the wedge becomes inaccurate.

It is an object of the present invention to provide a pull-out device for a household refrigerator and a household refrigerator, in which the decoupling of food storage units can be done easily and safely.

This object is achieved by a pull-out device and a household refrigerator according to the independent claims.

One aspect of the invention relates to a pull-out device for a household refrigerator. The extension device is designed for storing food on different levels. The food can be applied directly to this extractor itself. The pull-out device has a first food storage unit, which is arranged on a first level, viewed in the height direction of the pull-out device. The first food storage unit is slidably mounted in an extension direction which is oriented perpendicular to this height direction. Food can be applied or incorporated directly on this food storage unit. The pull-out device has a second food storage unit that is separate from the first food storage unit and that is arranged on a second level that is different from the first level. Also on this second food storage unit food can be applied directly. The extension device also has a coupling device with which the food storage units can be coupled in their movements. In the motion-coupled state, the food storage units can be pulled together in the pull-out direction.

The coupling device has a coupling element, which is a one-piece bracket, which is resiliently deformable in itself, wherein the coupling element is arranged on a food storage unit. The coupling device has a first stop, which is arranged on the other food storage unit, wherein the coupled state of the food storage units is formed by the coupled state between the coupling element and the stop. A release of this coupled state can be generated by a resilient deformation of the one-piece bracket, in the state adjacent to the stop of the bracket, and a transfer of the bracket over the stop, in the extension direction behind the stop.

Preferably, the bracket is V-shaped. This is a very advantageous form to achieve the very accurate and metered in the I deformation of the one-piece bracket. It does not cause undesirable abrupt deformation and yet allows for continuous deformation so that continuous transfer over the first stop is possible, and the release of the coupled state in a continuous movement takes place without sudden snap over.

Preferably, the bracket is attached to a bottom of the V-shape on the food storage unit, in particular screwed. This is advantageous in that the bracket is held relatively centrally with respect to its shape and therefore the stirrup legs of the stirrup are arranged maximally freely cantilevered and thus with the best possible spring action.

Preferably, the bracket has a first stirrup leg, which projects in the extension direction in the movement path, which is oriented in the extension direction and opposite to the extension direction, the first stopper. In particular, the first stirrup leg is resilient and in particular deformable.

Preferably, the bracket made of plastic, in particular POM (polyoxymethylene) is formed. As a result, it is lightweight and particularly suitable in conjunction with its shape to continuously undergo deformation.

Preferably, the first stop has a front coupling surface, which is designed as an inclined coupling ramp, wherein the inclined position is designed such that a lower end in the extension direction is arranged further forward, as an upper end of this first coupling surface. As a result, a particularly advantageous sliding along the strap is made possible at the first stop, because the bracket is in the coupled state with a first bracket leg at this first, forwardly oriented coupling surface fitting. In this coupled state, the strap is in an undeformed home position. During the release process of the coupled state, this stirrup leg then slides backwards on this first coupling surface, and the oblique position assists in the continuous deformation of the stirrup, so that a jerk-free decoupling is made possible. After transferring over a ramp tip, which is formed by the making of the two inclined coupling surfaces, the strap is automatically returned to the undeformed state by its own elasticity.

Preferably, the first stop has a second coupling surface, which is formed as an inclined coupling ramp, wherein the inclined position is formed such that a lower end (viewed in the vertical direction) of the second coupling surface is arranged in the extension direction further back, as an upper end of this second coupling surface. As a result, a correspondingly advantageous coupling between the first stop and the bracket is achieved. This to the effect that when inserting the first food storage unit in the inserted end position before reaching this end position of the first stop coupled with this rear second coupling surface and thus comes into contact and slides on further insertion of the first food storage unit of the strap on this second coupling surface , is thereby deformed and then led to the first stop.

In particular, the stirrup, in particular the first stirrup leg, is transferred via a ramp tip, which is formed by the two adjoining stubble shells. After passing over this ramp tip, the deformation is reversed again until the bar has returned to its undeformed ground state.

Preferably, the two coupling surfaces open at their upper ends to each other. As a result, a double-sided ramp is formed in the direction of extraction and insertion.

Preferably, the second coupling surface has a smaller inclination than the first coupling surface.

In particular, the extension device has a release stop, to which the second food storage unit in a pull-out position, which is reached when pulling the coupled food storage units in the extension direction, strikes, so that in a further extension of the first food storage unit in the extension direction of the bracket through a relative movement to the first stop in the coupled to the first stop state is deformable in itself and can be transferred via the first stop, so that the decoupled state of the food storage units is reached.

Preferably, the extension position, starting from the inserted basic position, corresponds to a movement path which corresponds to between 40% and 70% of a total movement path between an inserted basic position and a fully extended end position of the first food storage unit.

It can also be provided that in a specific extension position, which may be formed according to the above-mentioned, a pull-out force on the first food storage unit is so large that a deformation threshold of the bracket is exceeded, and this bar is then automatically into me so resiliently deformed, that the first stop is pulled under the bracket forward and thereby the coupled state is released.

It is preferably provided that viewed in the height direction, the second food storage unit is arranged higher lying than the first food storage unit. In particular, thus the second level is formed above the first level. Viewed in height direction, the two food storage units are arranged spaced from each other. This distance is preferably dimensioned such that food can be introduced on the lower food storage unit, which is formed in particular by the first food storage unit, even if the two food storage units viewed in the depth direction of the pull-out device, through which the Extent direction is specified, at least partially arranged overlapping. In particular, the distance in the height direction between these two food storage units is greater than a thickness of a beverage bottle.

Preferably, at least one food storage unit is designed for storing bottles on an upper side. Preferably, beverage bottles, in particular wine bottles, can be stored here. The pull-out device is then in particular a bottle-storage extraction device, in particular a wine-bottle storage extraction device.

It is preferably provided that receptacles, in particular depressions and / or perforations, are formed at least on one upper side of at least one food storage unit and are designed explicitly as bottle storage areas. As a result, bottles can be placed on the top of a food storage unit so that they are slip-proof or roll-safe. Such a storage area may be trough-like. It is also possible that a food storage unit is designed as a grid or as a rung structure, so that at least recesses, in particular complete openings, are formed between two bars or bar bars, so that a bottle can be placed in this area and is non-slip and roll secure positioned.

It is preferably provided that the first food storage unit is a bearing plate and / or the second food storage unit is a bearing plate. As a bearing plate in the context of both a full-surface design of a solid, board or shelf-like component understood. Likewise, however, a support plate is also understood to mean, for example, a grate or a strut framework or a truss framework.

Alternatively, however, at least one food storage unit may, for example, also be designed as a tray or trough-like container.

In such an embodiment, the food storage unit thus has a much greater height than a bearing plate, which is essentially defined only by its thickness in the height direction and therefore has a relatively low height.

In an advantageous embodiment, it is provided that the food storage units in the decoupled state are independently displaceable against the extension direction. This then also means that, in particular after decoupling, the upper, in particular second, food storage unit can be inserted independently of the lower, in particular first, food storage unit. Also, the first food storage unit can then be inserted counter to this extension direction in particular subsequently after the insertion of the upper food storage unit and brought into their final inserted state.

It is preferably provided that the first stop of the coupling device is formed on the first food storage unit. In its trajectory when pulling out the first food storage unit in the extension direction is the stop for separate coupling element of the coupling device, which is arranged on the second food storage unit, projecting into and coupled to the first stop. This means that viewed in the width direction of the pullout device, this first stop and this coupling element are at least partially overlapping, so when pulling out, especially the first food storage unit, in the extension direction of the first stop automatically contacted the coupling element and thus coupled with this, so from this coupled state both food storage units are motion-coupled and pulled out when moving out in the extension direction both food storage units in parallel. Such a configuration allows a very simple coupling concept, which is mechanically stable and robust and safely allows the coupling, on the other hand is designed to save space.

It is preferably provided that a second stop is formed on the first food storage unit, which is in particular spaced from the first stop and formed separately from the first stop. The second stop is arranged in the movement path of the second food storage unit, so that when the second food storage unit is extended in the extension direction, the second food storage unit strikes against the second stop and, with further extension of the second food storage unit in the extension direction, the first food storage unit Storage unit is extendable. By such a concept it is thus possible that regardless of which of the two food storage units used by a user and directly manually be pulled out, the other food storage unit is automatically pulled out at least from a certain reached extract position. However, this coupling of the food storage units on the second stop is always decoupled, because after completing the extraction, a movement against the extension direction can take place. In particular, therefore, this coupling via the second stop is not a locked coupling, which would have to be explicitly solved by a release operation again only to be able to insert the second food storage unit alone against the extension direction can. In particular, this second stop is an upwardly projecting stop, which is designed in particular as a ramp which forms the stop flank with its vertical flank.

It is preferably provided that the first stop and the second stop considered in the depth direction of the extension device are arranged offset from one another, wherein the first stop is arranged further back than the second stop.

In an advantageous embodiment, it is provided that the extension device has a front wall, which is connected to the lower, in particular first, food storage unit. In particular, this front wall is designed and arranged such that, when viewed from the front, both food storage units are concealed by this front wall.

It is provided in particular that the pull-out device is designed as a drawer, so that the preferably existing front wall is a front wall of the drawer. It is thus provided in this embodiment that the second food storage unit is arranged quasi as a displaceable unit in this drawer. If the drawer is closed, the food storage units are not accessible from the front. If the pull-out device is actuated on the basis of an inserted state, practically only the front wall can be gripped and pulled out in the context, so that in such an embodiment the lower, in particular first, food storage unit is automatically pulled out in the pull-out direction and off certain extension length, the coupling is coupled in motion with the upper, in particular second, food storage unit via the coupling device.

It is preferably provided that the coupling element viewed in the width direction of the extension device is arranged without overlapping to the second stop, so that in a relative movement of the food storage units in the extension direction or against the extension direction and thus in a pull or push a coupling of the coupling element and the second stop always is avoided.

It is preferably provided that the two stops are integrally formed on a support member, in particular the one-piece support member is formed as an L-shaped angle.

By such a configuration, the attacks are positionally stable and mechanically stable. In addition, they can be stably fixed by the carrier part to the food storage unit, in particular be arranged on an upper edge of such a food storage unit.

Another aspect of the invention relates to a household refrigerator with a housing in which at least one receiving space for food is formed. The domestic refrigerator has a pull-out device according to the above-mentioned aspect or an advantageous embodiment thereof. The extension device is arranged in the depth direction of the household refrigerator slidably in the receiving space.

In an advantageous embodiment, it is provided that the pull-out device can have pull-out rails, in particular telescopic rails. These pull-out rails make it possible to extract the food storage units in the pull-out direction. The pull-out rails are different components to the food storage units. The pull-out rails can be arranged on the food storage units.

Another aspect of the invention relates to a method for operating a pull-out device for a household refrigerator. The pull-out device allows food to be stored at different levels. A food storage unit of the pull-out device is arranged on a first level. This first food storage unit can be moved in the extension direction and is stored accordingly. A second food storage unit of the pull-out device is arranged on a second level different from the first level, wherein the pull-out device has a coupling device with which the food storage units can be coupled in their movements. In the motion-coupled state, the food storage units can be pulled out together in the extension direction.

A motion coupled state of the food storage units is provided by resiliently deforming a one-piece bracket, in the state abutting against a first stop of the bracket, and transferring the bracket over the stop in the extension direction behind the stop solved or decoupled. The bracket is deformable in itself and thus formed resiliently. It is a coupling element of the coupling device and arranged on one of the food storage units. The first stop is part of the coupling device and arranged on the other food storage unit.

Advantageous embodiments of the above-mentioned pull-out device are to be regarded as advantageous embodiments of the method, to allow representational components of the pullout device alone or in operative connection, the respective process steps of the method or perform.

Preferably, the household refrigerating appliance has a receiving space, which can be closed at the front by two separate doors. These two separate doors are arranged in the width direction without overlapping each other and extend in the closed state in a plane which is spanned by the height direction and the width direction. Preferably, the household refrigerator has a second receiving space, which is designed for storing food. This second receiving space can be designed to receive the pull-out device.

In 1 is a household refrigerator 1 shown, which is designed for storing and preserving food. The household refrigerator 1 is in the embodiment, a refrigerator-freezer combination device. The household refrigerator 1 has a housing 2 on, in which a plurality of separate receiving spaces are formed for food. In this context is a first recording room 3 formed, which is formed in the present embodiment as a cooling compartment. In addition, the household refrigerator has 1 one in height direction ( y Direction) formed thereunder receiving space 4 on which, for example, a partial volume of the receiving space 3 can represent. In the recording room 4 In one embodiment, a different air humidity and / or a different temperature to the remaining remaining partial volume of the receiving space 3 be adjustable. It can also be provided in particular that the receiving space 4 as the recording room 3 separate receiving space is formed. This receiving space can also be, for example, a bottle storage room, in particular for wine bottles.

In the exemplary embodiment it is provided that the receiving space 3 can be closed by a plurality of separate, front-side arranged doors. The recording room 4 is in the context of a door 5 lockable, here a front wall one in the depth direction ( z Direction) linearly displaceable drawer. The remaining partial volume of the recording room 3 is through two more separate doors 6 and 7 lockable, which are about vertical axes and thus oriented in the vertical direction axes separately and independently pivotable. By this configuration, on the one hand, the remaining part volume of the receiving space 3 which is not through the recording room 4 is formed, regardless of the recording room 4 be opened and closed, which by corresponding pivoting of the doors 6 and or 7 he follows. Again independently of this, then the recording room 4 be opened by the door 5 is opened and thus the drawer is pulled out.

The household refrigerator 1 In the exemplary embodiment, moreover, two further separate receiving spaces 8th and 9 which are freezers. There may also be only one freezer or none of the freezers available.

The two freezers are also in turn by separate doors 10 and 11 closed, and here in the embodiment shown, these doors 10 and 11 Front walls of linearly displaceable in the depth direction drawers are. For example, it is shown that the lower freezer through the door 11 trained front wall of a drawer 12 lockable, this drawer 12 shown here in pulled out condition.

The recording rooms 3 . 4 . 8th and 9 are limited by an inner container, which is in particular made of plastic.

In the following explanation is provided in the embodiment that in the receiving space 4 a pull-out device 13 is arranged. This pullout device 13 is in the embodiment for storing food, here in the form of bottles, especially wine bottles trained. This pullout device 13 is linearly displaceable in the depth direction in the receiving space 3 stored. The pullout device 13 is designed here as a drawer and shows next to the front wall, through the door 5 is formed, two food storage units 14 and 15 on. The first food storage unit 14 is viewed in the height direction, the lower food storage unit. This first food storage unit 14 is designed as a bearing plate and thus as a tray or tray. It is designed in the exemplary embodiment shown as a strut structure to hang up the bottles roll safe can.

The second food storage unit 15 In the exemplary embodiment, it is likewise designed as a bearing plate and thus as a tray or tray, and here too it is preferably designed as a strut structure. In the embodiment shown are two bottles by way of example 16 and 17 on this upper food storage unit 15 arranged horizontally.

The first food storage unit 14 is stuck with the door 5 connected. The pullout device 13 is designed here as a drawer. As in 3 to recognize which subcomponents of the representation in 2 shows in a different perspective, the pull-out device 13 support parts 18 and 19 on. These support parts 18 and 19 at the same time also represent sidewalls, which is a storage space between the lower, first food storage unit 14 and the upper, second food storage unit 15 limit in width direction on opposite sides. These support parts 18 and 19 are on margins with the first food storage unit 14 connected, especially with the door 5 connected. As in 3 can be seen, is on an outer side of the support member 19 a pull-out rail 20 , in particular a telescopic extension arranged. This allows the extension device 13 are linearly pushed back and forth in the depth direction and thus in the extension direction (positive z Direction) and be moved against this extension direction.

The second food storage unit 15 also has a separate pull-out rail 21 on, which is preferably also a telescopic extension. Through this pull-out rail 21 , which is also formed on the opposite side, the food storage unit 15 viewed in the direction of the depth are pushed back and forth, especially independent of the first food storage unit 14 , The same applies to the opposite carrier part 18 a pull-out rail 20 arranged in 2 and 3 is not recognizable.

The pull-out rails 20 and 21 are preferably on inner sides and vertical side walls of an inner container, the receiving space 4 limited, arranged. They preferably each have a fixed rail, which is fixedly attached to these side walls, and is a movable running rail on.

As in 3 can be seen, the specifications mentioned are designed as bearing plates such that between two parallel rungs 22 and 23 at least one trough, in particular an opening 24 , is trained. One on such a receiving area 25 or storage area introduced or launched bottle is thus then slip-proof and roll secure positioned.

The pullout device 13 moreover has a coupling device 26 on. Through the coupling device 26 are the food storage units 14 and 15 in specific positions coupled to each other and thus thereafter motion coupled.

Through the coupling device 26 In particular, it is achieved that in the fully inserted state of both food storage units 14 and 15 these are decoupled. Will be the first food storage unit 14 pulled out of this inserted end position in the extension direction, in particular by grasping and pulling out the door 5 , is from a particular defined intended pull-out position of this first food storage unit 14 coupling with the second food storage unit 15 reached. From this motion coupled state, both food storage units will become 14 and 15 on further undressing in undressed pulled out together.

In 4 is a subset of the components as they are in 3 shown are shown. As can be seen here, the extension device 13 a carrier part 27 on, which as a separate component to the plate-like support member 18 is arranged, in particular is arranged at an upper edge. The carrier part 27 is here in the exemplary embodiment preferably L-shaped. It has an integrated first stop 28 on, the component of the coupling device 26 is. At the second food storage unit 15 is a coupling element 29 arranged, in particular movable, preferably pivotable, arranged thereon. The pivot axis is oriented in the width direction. This coupling element 29 which is also part of the coupling device 26 is, in the width direction at least partially overlapping with this first stop 28 arranged. Thus, upon extension of the first food storage unit 14 the stop 28 on its path of movement then arranged in the depth direction before coupling element 29 Touch, as this in the trajectory of the first stop 28 located. Once this contacting has been achieved, then the coupled state between the food storage units is also present 14 and 15 given.

The coupling element 29 is a one-piece strap 30 , The coat hanger 30 is elastically deformable in itself and thus resilient in itself. The coat hanger 30 is in particular made of plastic, in particular POM. Preferably, the bracket 30 is V-shaped, which in particular generally also includes a notch-like or groove-like shape, in particular also a U-shape is included. The coat hanger 30 has a first stirrup leg 30a up, from the second food storage unit 15 down towards the first food storage unit 14 sticking out. A second stirrup leg 30b is in the second food storage unit 15 arranged and arranged adjacent to a support. In particular, this creates a counterforce to deforming. In particular, the first bracket leg 30a curved, as in 5 is shown.

At one V -Ground 30c of the V Shape is the temple 30 at the second food storage unit 15 attached, in particular screwed. A screw connection 36 is shown.

As can also be seen, the first stop points 28 a first coupling surface 28a on, which is tilted. The inclination or inclination is such that a lower end in the height direction of this first coupling surface 28a , viewed in the depth direction, is arranged further forward than an upper end of this first coupling surface 28a , Furthermore, the first stop 28 a second coupling surface 28b up, which is also inclined. This inclination or inclination is such that an upper end in the height direction of this second coupling surface 28b , viewed in the depth direction, is arranged further forward than a lower end of this second coupling surface 28b , In particular, the two coupling surfaces open 28a and 28b with their upper ends to each other.

The first stop 28 is thus formed on both sides like a ramp. Through the coupling surfaces 28a and 28b is formed a rising and a sloping ramp edge. At the appointment at the upper ends of the coupling surfaces 28a and 28b a ramp tip is formed. The coat hanger 30 can on both coupling surfaces 28a and 28b slide along, in particular by respective intrinsic deformation, to solve the coupled state or bring about the coupled state.

As well as in 2 to 4 can be seen is provided in the embodiment, that the pullout device 13 a second stop 31 having. In particular, this second stop 31 in the carrier part 27 integrated. Considered in the depth direction is in an advantageous embodiment of the second stop 31 arranged further forward than the first stop 28 , As can also be seen, is the first stop 28 on a vertical leg 32 this L-shaped support part 27 and the second stop 31 on a horizontal leg 33 this support part 27 educated. The second stop 31 extends from the top of this horizontal leg 33 upwards and here is designed ramp-shaped. Preferably a vertical flank 34 this second stop 31 serves as a stop surface for a counter stop surface 35 the second food storage unit 15 , By this configuration, it is also achieved that the second food storage unit 15 viewed in the extension direction relative to the first food storage unit 14 can be pulled forward, but maximum up to this second stop 31 , As in particular in 4 can be seen, viewed in the depth direction, a distance between the first stop 28 and the second stop 31 formed, so in this regard, the maximum relative displacement distance in the extension direction between the two food storage units 14 and 115 in an explicit pulling out of the second food storage unit 15 is defined.

A corresponding embodiment is also in the opposite carrier part 19 provided so that here also a correspondingly shaped support part 27 is arranged, as well as in 3 can be seen.

In 5 is a partial enlarged view of the extension device in a further enlarged view 13 shown. In this embodiment, when viewed from the front, the right-hand portion of the extension device 13 shown. In this embodiment is shown as an example, as the counter-attack surface 35 to the stop surface 34 is applied.

In 6 is the position of the components according to 5 in a different perspective, namely from the front and from below, shown. As can be seen explicitly here, the two attacks 28 and 31 in the width direction of the extension device 13 considered arranged without overlap to each other. In particular, the coupling element is also 29 viewed in the width direction without overlap to the second stop 31 arranged. This is in every position of the food storage units 14 and 15 avoided that the coupling element 29 and the second stop 31 could contact each other.

In 6 is the coupled state between the food storage units 14 and 15 and thus between the first stop 28 and the hanger 30 , in particular the first stirrup leg 30a shown. The first hanger leg 30a lies on the front, first coupling surface 28a at. Starting from this, the first food storage unit 14 pulled out in the extension direction, so reaches the second food storage unit 15 , which is pulled out with, a release stop, not shown, and is further hindered with undressing. As a result, the first stop is moved further in the extension direction and relative to the first bracket leg 30a emotional. Due to the inclined coupling surface 28a then slides the first stirrup leg 30a along this slope along and is resiliently deformed, is the bracket 30 guided with his hanger arm on the ramp tip, the coupled state is decoupled, and the first bracket leg 30a automatically returns to the undeformed ground state. The second food storage unit 15 can now be independent of the first food storage unit 14 be pushed back against the extension direction. In the following then also the first food storage unit 14 pushed back, so contacted the second coupling surface 28b Coming from the front, the first stirrup leg 30a , Because the second food storage unit 15 In particular, already arranged in the inserted final state, we thereby built up a counterforce and the first stop 28 moves relative to the first stirrup leg 30a backwards until the first stirrup leg 30a by the deformation when passing along the second coupling surface 28b when transferring over the ramp tip again in the coupled state with the first stop 28 is converted.

Alternatively, instead of a release stop, a force threshold value may also be predetermined, in which case it is achieved by a pull-out force with which the first food storage unit 14 is pulled out, the strap 30 when passing along the first coupling surface 28a is deformed in itself and is transferred via the Rampenspitze and thereby the decoupled state is generated.
