Description

The invention relates to a guide arrangement for guiding a refrigerated goods container in a refrigeration appliance and a combination of a refrigerated goods container for a refrigeration appliance and a storage area for storing the refrigerated goods container in the refrigeration appliance.

A refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance which is used for household purposes or possibly also in the gastronomy sector and serves, in particular, to store foods and / or drinks in household quantities at specific temperatures, such as, for example, a refrigerator Freezer, a fridge-freezer, a freezer or a wine storage cabinet.

Refrigerated goods containers are usually enclosed on five sides containers in which refrigerated goods such as vegetables can be stored in a refrigerator. In most cases, they can be pulled out or removed from the interior of the refrigerator in order to fill them better or to remove refrigerated goods stored in them more easily.

In order to be able to pull out a refrigerated goods container simply from a refrigerating appliance or from a storage area of the refrigerating appliance on which the refrigerated goods container is accommodated, the refrigerated goods container and / or the storage area often have special arrangements with which the refrigerated goods container can be moved more easily on the storage area ,

For example, as in DE 10 2010 039 644 A1 or in DE 10 2010 039 651 A1 shown, rollers provided under a front or rear portion of a bottom of the refrigerated goods container, which run on a corresponding mating surface of the bearing surface.

It is also known to provide rollers not only under the bottom of the refrigerated goods container, but also in a side region, wherein the lateral rollers in a guide in the wall of the refrigerator are guided, such as in DE 92 06166 U1 is shown.

Additionally, for example, in JP 09 280 727 A Also described arrangements in which both on the refrigerated goods and on the running surface wheels are present.

The EP 0 594 960 A1 discloses a refrigerated goods container.

The DE 10 2010 039 644 A1 discloses a refrigeration device with an extendable refrigerated goods container.

The DE 101 54 274 A1 discloses a refrigerator and an excerpt therefor.

The DE 198 58 378 A1 discloses a refrigeration device.

The US 1,758,550 discloses a holding means for drawers for furniture.

The DE 197 56 855 A1 discloses a device for slidably holding a compartment received between two side walls.

The aim of the known guide arrangements is not only easier to pull the refrigerated goods from the storage area, but also often to create a reduced noise when pulling out.

The object of the invention is to propose a further improved in these aspects guide arrangement for a refrigerated goods.

This object is achieved with a combination according to claim 1 as a first aspect and claim 7 as a second aspect.

The combinations comprise a refrigerated goods container for a refrigeration device and a bearing surface for storing the refrigerated goods container in the refrigeration device.

Advantageous embodiments of the invention are the subject of the dependent claims.

A guide arrangement for guiding a refrigerated goods container in a refrigerator has a guide roller and a guide rail for guiding the guide roller. The guide rail has a tread arranged radially to the guide roller and an axially disposed to the guide roller guide profile. The guide profile is spaced from the guide roller and arranged to the tread.

The guide roller on the refrigerated goods container and the guide rail are arranged on the bearing surface. It is arranged the leadership role embedded in a bottom portion of the refrigerated goods.

According to the first aspect, a roller for guiding the refrigerated goods container is arranged at one end of the tread, which is in particular rotatably but fixedly connected to the tread and more in particular at least partially sunk in the tread. Further, a running groove for guiding the roller is provided, so that the roller is advantageously performed as well as the guide roller in the direction of the refrigerated goods and thus a lateral displacement of the refrigerated goods container can preferably be prevented.

According to the second aspect, the portion of the guide roller, which is encompassed by the guide profile, formed by an axial engagement projection for engagement with the guide profile. The engagement projection is disposed on an axis of the guide roller. This is according to a variant be a pin which protrudes on the axis of rotation of the guide roller in the direction of the U-web of the guide profile over the edges of the guide roller. According to another variant, the engagement projection is formed by a support roller, which in a particularly preferred embodiment has a smaller diameter than the guide roller

The guide rail can thus be designed for the exact spatial guidance of the guide roller without at the same time providing the running surface for the guide roller. Thus, optimized materials can be selected both for the guidance and for the running surface of the guide roller.

Suitable materials of the guide profile and tread can be chosen so that on the one hand reduces the frictional resistance and thus a low-noise operation of the refrigerated goods on the tread are achieved and on the other hand high stress of the guide profile can be made possible without major wear.

A lateral guidance of the guide roller through the profile is preferred over a guide at the bottom of the refrigerated goods container, as a guide of the guide roller can be achieved not only along the withdrawal direction of the refrigerated goods, but also in the radial direction of the guide roller up and down.

Therefore, the guide profile in a preferred embodiment surrounds at least a portion of the guide roller.

Thus, guidance of the guide roller by the guide profile is advantageously realized in the radial direction as well as in the axial direction of the guide roller, since the guide profile can preferably prevent the guide roller from shifting laterally or upwards or downwards.

Preferably, the tread has a guide groove for guiding the guide roller therein.

Thus, the guide roller is advantageously not only guided by the guide profile, but also in the withdrawal by the guide, so that preferably a comfortable pulling out of the refrigerated goods through the tread is made possible.

In a particularly preferred embodiment, the guide profile and the tread are integrally formed.

By integrally forming the guide profile and tread, the assembly of the guide arrangement on a bearing surface in a refrigeration device is preferably simplified and the manufacturing process of the refrigeration device more efficient overall.

Preferably, according to the first aspect, the partial area of the guide roller, which is encompassed by the guide profile, is formed by an axial engagement projection for engagement with the guide profile. Advantageously, the engagement projection on an axis of This may, for example, be a pin projecting on the axis of rotation of the guide roller towards the U-web of the guide profile beyond the edges of the guide roller. Alternatively, the engagement projection can also be formed by a support roller, which in a particularly preferred embodiment has a smaller diameter than the guide roller.

Advantageously, the guide profile is formed as a U-profile with a first U-leg and a second U-leg, which is opposite to the first U-leg, wherein the first U-leg for forming the tread is longer than the second U-leg.

Thus, the guide profile preferably engage around the guide roller with a U-web and the second, shorter U-leg and further advantageously at the same time form the running surface on which the guide roller runs through the first, longer U-leg.

In a particularly preferred example, when the chilled goods container is pulled out, the support roller only contacts the second U-leg, for example, but not the first U-leg of the guide rail, for example. Thus, it does not obstruct the extraction of the refrigerated goods container advantageously, since it preferably causes only a slight friction.

However, as soon as the refrigerated goods container has been completely pulled out over the running surface and threatens to tip forward, for example, the supporting roller advantageously maintains contact with the second U-leg of the guide rail and thus supports the refrigerated goods container against falling out of the bearing surface of the refrigerating appliance.

More preferably, the guide roller has at least one radial guide pin for engagement with the guide groove.

In an exemplary embodiment of this radial guide pin is continuously formed circumferentially around the circumference of the guide roller, so that during the running of the guide roller advantageously permanently a portion of the pin is in engagement with the guide groove and allows the guide in the guide groove.

Particularly preferably, the guide pin is arranged on the guide roller, that it divides it into two substantially equal half-roles. For example, the pin is preferably arranged in the middle of the running surface of the guide roller. Thus, the guide roller advantageously uniformly engages with the guide groove, wherein on both sides of the guide roller preferably uniform support surfaces are provided for stabilizing the guide roller on the tread.

Advantageously, according to the second aspect, a roller for guiding the refrigerated goods container is arranged at one end of the running surface, which is in particular rotatably but fixedly connected to the running surface and more particularly at least partially sunk in the running surface.

Accordingly, when the refrigerated goods container is running over the running surface, not only the region of the refrigerated goods container is advantageously guided on a roller on which the guide roller is arranged, but also further regions of the refrigerated goods container which are in contact with the roller. If the roller and the guide roller are preferably arranged opposite one another in the inserted state of the refrigerated goods container, then a run of the refrigerated goods container over the running surface can be provided, which is preferably limited predominantly only by slight rolling friction.

Preferably, according to the second aspect, a running groove for guiding the roller is provided, so that the roller is advantageously performed as well as the guide roller in the direction of the refrigerated goods and thus lateral displacement of the refrigerated goods container can preferably be prevented.

Advantageously, the materials, in particular plastic materials, of guide, running and / or support roller and guide rail selected such that when passing a refrigerated goods a low friction noise.

A corresponding combination of a refrigerated goods container for a refrigeration device and a storage area for storing the refrigerated goods container in a refrigeration device has the above-described guide arrangement.

Preferably, in the inserted state of the refrigerated goods container on the bearing surface, the roller is arranged on the bearing surface opposite to the guide roller.

Advantageously, the support roller is formed on the refrigerated goods, particularly preferably on an axis of the guide roller and is in a preferred embodiment laterally over a side wall of the refrigerated goods to the outside.

In a further advantageous embodiment, the running groove is formed integrally with the refrigerated goods container. This advantageously simplifies the manufacturing process of the refrigerated goods container and the guide arrangement.

Preferably, the guide rail is formed integrally with the bearing surface. This is always advantageous, for example, if the storage area is formed, for example, by a refrigerated goods carrier on which the refrigerated goods container is to be stored. This also makes it possible to simplify the manufacturing process of the guide arrangement or the bearing surface.

This is possible, for example, if the bearing surface and / or the refrigerated goods container are made of plastic materials, in particular by injection molding.

Fig. 1 shows a refrigerator 10 with a combination 12 of a refrigerated goods 14 and a storage area 16 in the refrigerator 10. The combination 12 of refrigerated goods 14 and storage area 16 is in more detail without the refrigerator 10 again in Fig. 2 shown.

In a side region 18 of the combination 12 of refrigerated goods container 14 and bearing surface 16, a guide arrangement 20 for guiding the refrigerated goods container 14 via the bearing surface 16 of the refrigeration device 10 is arranged.

Fig. 3 shows a view from an opening side 22 of the refrigeration device 10 on the combination 12th

As in Fig. 3 can be seen, the guide assembly 20 is formed on both side regions 18 of the combination 12. For reasons of clarity, only the guide arrangement 20 in one of the two side areas 18 will be described below, but the opposite guide arrangement 20 is executed equally.

The guide arrangement 20 has both a guide roller 24 below a bottom region 25 of the refrigerated goods container 14 and a guide rail 26 arranged on the bearing surface 16. In Fig. 3 In this case, in particular, the part of the guide rail 26 arranged perpendicularly to the bearing surface 16 can be seen.

In this vertical part, the guide rail 26 has a guide profile 28 which engages around an axial engagement projection 30, which is arranged on an axis 32 of the guide roller 24 and projects beyond a side wall 33 of the refrigerated goods container 14 to the outside. The axial engagement projection 30, a web 34 and a second U-leg 36 of the guide profile 28, which is formed as a U-profile 38, thereby form a positive fit, which the engagement projection 30 even when tilting the refrigerated goods container 14 down to the second U Leg 36 stops.

The engagement projection 30 is formed by a support roller 40, which runs along when pulling out the refrigerated goods container 14 from the bearing surface 16 on the second U-leg 36. The support roller 40 is in detail in the Figs. 5 and 7 shown.

Below the guide roller 24, i. in the radial direction of the guide roller 24 on the bearing surface 16, the guide roller 24 runs on a tread 42nd

The guide profile 28 and the tread 42 are in the in Fig. 3 and Fig. 6 embodiment shown integrally formed, wherein the tread 42 is formed by a first U-leg 44 of the guide profile 28. However, it is also possible to provide the running surface 42 and the guide profile 28 as separate elements, wherein it is preferred that the guide profile 28 is not formed by a U-profile 38, but by an L-profile.

The tread 42 is in more detail in FIG Fig. 4 shown.

The running surface 42 has a guide groove 46, in which the guide roller 24 can be guided. For this purpose, the guide roller 24 has a radial guide pin 48, which is in engagement with the guide groove 46. The radial guide pin 48 is formed in the circumferential direction on the circumference 50 of the guide roller 24 and divides, as in Fig. 3 While the radial guide pin 48 in the guide roller 46 runs, run the two half rollers 52 of the guide roller 24 in comparison to the guide groove 46 raised portions 54 of the tread 42nd

As Fig. 6 it can be seen, however, the guide groove 46 can also be omitted and the leadership of the guide roller 24 is realized only by the lateral guide profile 28.

At one of the guide roller 24 opposite end 56 of the tread 42 in Fig. 4 a roller 58 is arranged, on which the refrigerated goods container 14 can be guided. This roller 58 is fixed but rotatably mounted sunk in the tread 42.

At the same time, the refrigerated goods container 14 has a running groove 60, in which the roller 58 is guided.

If the materials for the guide roller 24, the roller 58, the support roller 40, the tread 42 and the running groove 60 are selected from appropriately matched materials, the friction and in particular the emergence of frictional noise when removing the refrigerated goods container 14 can be reduced from the bearing surface 16 ,

Accordingly, a system is proposed with which a refrigerated goods container 14 can be easily removed from the designated container such as a refrigerator 10 or a freezer. This system can be implemented via additional elements which are attached to the conventional refrigerated goods container 14 and / or to the container.

Chilled goods containers 14 are known with several rollers attached to the rear side or systems in which the refrigerated goods 14 is moved via full or partial extracts or only by sliding the refrigerated goods container 14 in the container with and without guide geometry.

As a result of the fact that rollers in connection with guide rails 26 are additionally attached to the refrigerated goods container 14 and to the container, that is to say the refrigeration device 10, an improved running and guiding behavior is achieved. Here, the guide rails 26 and the front rollers, namely the rollers 58, mounted on the container. On the refrigerated goods 14, however, are located in the rear part of the refrigerated goods 14 additional roles, the guide rollers 24, which take over simultaneously sliding and guiding tasks.

By attaching rollers in the container and by providing guide grooves 46 in the guide rails 26, a more accurate movement of the refrigerated goods container 14 is achieved. In combination with different materials, a significantly better running noise or sliding behavior is achieved than before.

The geometry of the guide rails 26 and another small role, the support roller 40, in the rear of the refrigerated goods 14 prevent tilting of the refrigerated goods 14 in the extended state forward. Tendiert the refrigerated goods 14 for tilting the rear roller of the refrigerated goods container 14 is held on the upper wall of the guide rail 26 and takes over from this date the guiding or sliding function. This combination of several roles facilitates the removal of the refrigerated goods container 14, the handling of the refrigerated goods container 14 and reduces dragging noises, which may also indicate a generation of abrasion.
