Description

Technical field

The invention relates to a guide assembly for a container for chilled products in a refrigeration device, as well as a combination of a container for chilled products for a refrigeration device and a supporting surface for supporting a container for chilled products in a refrigeration device.

State of the art

A refrigeration device is understood to mean, in particular, a domestic refrigeration device, that is, a refrigeration device that is used for housekeeping in households or in the gastronomic field, and, in particular, serves to store food and / or drinks at a set temperature - such as, for example, a refrigerator, freezer, combination fridge-freezer, freezer or wine refrigerator.

The containers for chilled products are predominantly closed containers on five sides, in which it is possible to store chilled products, for example, vegetables, in the refrigerator. In most cases, they are made with the possibility of their extension or removal from the inner region of the refrigeration apparatus, so that they can better fill them or easier to extract from them cooled products.

In order to be able to easily slide the chilled food container out of the refrigerator or from the supporting surface of the chiller on which the chilled food container is located, the chilled food container and / or work surface often have special devices by which the chilled food container is moved around the work surface is simplified.

For example, as shown in patent documents DE 10 2010039644 A1 or DE 10 2010039651 A1, there are provided rollers under the front or rear region of the bottom of the container for chilled products that move along the corresponding rolling bearing surface.

It is also known that rollers can be provided not only under the bottom of the container for chilled products, but also in the side region, the side rollers being guided in the wall of the refrigerator, as shown, for example, in patent document DE 9206166 U1.

Additionally described, for example, in patent document JP 09280727 A, devices in which the running wheels are available both on the container for chilled products, and on the working surface.

Patent document EP 0594960 A1 discloses a container for chilled products.

DE 10 2010039644 A1 discloses a refrigeration apparatus with a drawer for chilled products.

DE 10154274 A1 discloses a refrigeration apparatus and a drawer for it.

DE 19858378 A1 discloses a refrigeration apparatus.

Patent document US 1758550 discloses a means for holding drawers of furniture items.

DE 19756855 A1 discloses a device for holding a shelf placed between two side walls with the possibility of its movement.

The purpose of the known guide assemblies is not only the possibility of more easily extending the container for chilled products from the supporting surface, but often also the reduction of noise produced by the extension.

Disclosure of invention

The objective of the invention is to propose a guide assembly for a container for chilled products with further improvement in these aspects.

This problem is solved by the combination according to paragraph 1.

The combination includes a chilled food container for a refrigeration apparatus and a supporting surface for supporting a chilled food container in a refrigeration apparatus.

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

The guide assembly for holding the container for chilled products in the refrigeration device has a guide roller and a guide for holding the guide roller. The guide has a working surface located radially relative to the guide roller, and a guide profile located axially relative to the guide roller. In this case, the guide profile is located at a distance both from the guide roller and from the working surface.

A roller for holding a container for chilled products is located at one end of the working surface, which is connected to the working surface, in particular with the possibility of rotation, but without the possibility of movement relative to it, and for the most part, in particular, at least partially, is buried in the working surface.

In addition, a running groove is provided for holding the running roller, so that the running roller is preferably held in the same way as the guide roller in the direction of movement of the chilled product container, and thus, lateral displacement of the chilled product container is preferably prevented.

In this case, the guide roller is located on the container for chilled products, and the guide is located on the supporting surface. The guide roller is in a recessed position on the bottom portion of the chilled food container.

Thus, it is possible to provide a guide for precise spatial guidance of the guide roller, while at the same time without providing a working surface for the guide roller. This allows you to optimally select materials for both the guide and the working surface of the guide roller.

Such a choice of suitable materials for the guide profile and work surface is possible that, on the one hand, friction resistance is reduced and, thus, the container for chilled products travels on the work surface with reduced noise and, on the other hand, a high load on the guide is provided profile without more wear.

Lateral guiding of the guide roller along the profile is preferable compared to guiding the bottom of the container for chilled products, since it is therefore possible to guide the guide roller not only along the extension direction of the chilled food container, but also in the radial direction of the guide roller, up and down.

Therefore, in a preferred embodiment, the guide profile covers at least one subregion of the guide roller.

Thus, it is realized that the guide roller is preferably guided along the guide profile both in the radial direction and in the axial direction of the guide roller, since the guide profile advantageously allows the guide roller to be prevented from moving sideways up or down.

The working surface preferably has a guide groove for guiding the guide roller therein.

Thus, the guide roller is preferably guided not only along the guide profile, but also in the direction of extension along the guide groove, so that it is possible to conveniently extend the container for chilled products on the working surface.

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

Due to the integral implementation of the guide profile and the working surface, mounting the guide assembly on the supporting surface in the refrigeration device is advantageously simplified, and the manufacturing process of the refrigeration device as a whole becomes more efficient.

The subregion of the guide roller that the guide profile covers is preferably formed by an axial engaging protrusion for engagement with the guide profile. The engaging protrusion is preferably located on the axis of the guide roller.

It can be, for example, a finger, which, being on the axis of rotation of the guide roller, protrudes beyond the edges of the guide roller in the direction of the U-shaped jumper of the guide profile. Alternatively, an engaging protrusion formed by a support roller is also possible, which in a particularly preferred embodiment has a smaller diameter than the guide roller.

The guide profile is preferably made as a U-profile with a first U-shelf and a second U-shelf, which is opposite the first U-shelf, and the first U-shelf for forming the working surface is longer than the second U-shelf.

Thus, the guide profile preferably covers the guide roller with a U-shaped jumper and the second, shorter U-shelf and at the same time the first, longer U-shelf, further forms a working surface along which the guide roller passes.

In a particularly preferred embodiment, when the chilled product container is pulled out, the support roller contacts, for example, only the second U-shelf, but not the first U-shelf of the guide. Thus, it preferably also does not interfere with the extension of the chilled product container, since it preferably causes only slight friction.

But as soon as the container for chilled products is fully extended on the working surface and is ready, for example, to tip over, the support roller preferably contacts the second U-shelf of the guide and thus keeps the container for chilled products from falling out of the support surface of the refrigeration device.

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

This radial guide pin in the example embodiment is made continuous, passing around the side surface of the guide roller, so that during the course of the guide roller, any region of the pin is preferably constantly engaged with the guide groove and allows the roller to be guided along the guide groove.

In a particularly preferred case, the guide pin is located on the guide roller in such a way that it divides it into two half-rollers of substantially the same size. For example, the pin is preferably located in the middle of the working surface of the guide roller. Then, the guide roller enters the guide groove evenly, moreover, on both sides of the guide roller, uniform support pads are preferably provided to stabilize the guide roller on the working surface.

When passing the container for chilled products along the working surface in accordance with this, preferably not only the region of the container for chilled products in which the guide roller is located, but also further regions of the container for chilled products that are in contact with the roller are preferably passed through the roller. If the running roller and the guide roller are preferably located opposite each other while the chilled food container is in the retracted state, it is possible to provide a chilled product container running on the working surface that is preferably limited mainly by only slight rolling friction.

The materials, in particular plastics, for the guide, guide and / or support roller and the guide are preferably selected so that the noise from friction that occurs when holding the container for chilled products is negligible.

A suitable combination of the chilled food container for the refrigeration device and the supporting surface for supporting the chilled food container in the refrigeration device has a guide assembly as described above.

In the retracted state of the chilled product container on the supporting surface, the running roller is preferably located on the supporting surface opposite the guide roller.

The support roller is preferably made on the container for chilled products, particularly preferably on the axis of the guide roller and, in a preferred embodiment, protrudes from the side to the outside, outside the side wall of the container for chilled products.

In a further preferred embodiment, the running groove is integrated in the container for chilled products. This advantageously simplifies the manufacturing process of the chilled product container and the guide assembly.

The guide is preferably made integrally with the supporting surface. This is preferable, for example, in all cases where the supporting surface is formed, for example, by a carrier element for chilled products, on which the container for chilled products must rest. It also advantageously simplifies the manufacturing process of a guide assembly or abutment surface.

This is possible, for example, if the supporting surface and / or the container for chilled products are made of plastic, in particular by injection molding.

The implementation of the invention

In FIG. 1 shows a refrigeration device 10 with a combination 12 of a chilled food container 14 and a support surface 16 in a refrigeration device 10. The combination 12 of a chilled food container 14 and a support surface 16 is again shown in more detail in FIG. 2 without refrigeration device 10.

In the side region 18 of the combination 12 of the chilled product container 14 and the supporting surface 16, a guide assembly 20 is arranged for guiding the chilled product container 14 along the supporting surface 16 of the refrigeration device 10.

In FIG. 3 shows a view of the combination 12 from the opening side 22 of the refrigeration device 10.

As seen in FIG. 3, the guide assembly 20 is formed in both side regions 18 of the combination 12. In the following, for clarity reasons, only the guide assembly 20 in one of both side regions 18 is described, but the opposite guide assembly 20 is made in the same way.

The guide assembly 20 has both a guide roller 24 below the bottom region 25 of the chilled product container 14 and a guide 26 located on the abutment surface 16. Moreover, in FIG. 3, in particular, a part of the guide 26 is seen, perpendicular to the supporting surface 16 and directed upward.

In this vertical part, the guide 26 has a guide profile 28, which covers an axial engaging protrusion 30 located on the axis 32 of the guide roller 24 and protruding outward beyond the side wall 33 of the container 14 for chilled products. In this case, the axial engaging protrusion 30, the jumper 34 and the second U-shelf 36 of the guide profile 28, made in the form of a U-shaped profile 38, form a geometric closure that holds the engaging protrusion 30 on the second U-shelf 36 even when capsizing the container 14 for refrigerated products down.

The engaging protrusion 30 is formed by a support roller 40, which, when the chilled product container 14 is pulled out from the support surface 16, extends along the second U-shelf 36. The support roller 40 is shown in detail in FIG. 5 and 7.

Bottom of the guide roller 24, i.e. in the radial direction of the guide roller 24 on the supporting surface 16, the guide roller 24 passes along the working surface 42.

The guide profile 28 and the working surface 42 in the embodiment shown in FIG. 3 and FIG. 6 are integrally formed, the working surface 42 being formed by the first U-shelf 44 of the guide profile 28. However, the working surface 42 and the guide profile 28 are also provided as separate elements, in which case the guide profile 28 is preferably not formed by U- shaped profile 38, and a corner profile.

Work surface 42 is shown in more detail in FIG. four.

The working surface 42 has a guide groove 46, in which it is possible to guide the roller 24. For this, the guide roller 24 has a radial guide pin 48, which is in cooperation with the guide groove 46. The radial guide pin 48 is made on the side surface 50 of the guide roller 24, directed around it and, as seen in FIG. 3 divides the guide roller 24 into two substantially equal-sized half-rollers 52. While the radial guide pin 48 extends along the guide groove 46, both half-rollers 52 of the guide roller 24 extend along regions 54 of the working surface 42 above the guide groove 46.

However, as follows from FIG. 6, it is also possible to exclude the guide groove 46, and the passage of the guide roller 24 is realized only thanks to the side guide profile 28.

On the opposite guide roll 24, end 56 of work surface 42 in FIG. 4, a running roller 58 is located along which it is possible to hold a container 14 for chilled products. This roller 58 is located on the working surface 42 with a recess in it, without the possibility of movement, but with the possibility of rotation.

At the same time, the container 14 for chilled products has a running groove 60 along which a running roller 58 is guided.

If the materials for the guide roller 24, the running roller 58, the supporting roller 40, the working surface 42 and the running groove 60 are selected from suitably suitable materials for each other, friction and, in particular, due to friction, noise generated when the chilled container 14 is pulled out can be reduced. products with a supporting surface 16.

Accordingly, a system is proposed by which it is possible to easily slide a container 14 for chilled products from a container provided for it, for example, from a refrigeration device 10 or a freezer. It is possible to implement this system by means of additional elements placed on a conventional container 14 for chilled products and / or in a conventional container.

Containers 14 for chilled products with several rollers placed on them on the rear side are known, or systems in which the container 14 for chilled products is moved by fully or partially extendable elements or also only by sliding the container 14 for chilled products in a tank with a guide geometry or without her.

Due to the fact that now on the container 14 for chilled products and in the container for it, i.e. in the refrigeration device 10, rollers are additionally placed in combination with the guide 26, improved conductivity and passage characteristics are achieved. In this case, the guide 26 and the front rollers, namely the running rollers 58, are mounted in the container. On the container 14 for chilled products in the rear of the container 14 for chilled products are additional rollers, guide rollers 24, which simultaneously serve for sliding and for setting the direction.

By placing the rollers in the container and the provided guide grooves 46 in the guide 26, a more accurate movement of the chilled product container 14 is achieved. In combination with various materials, significantly lower driving noise is achieved, or better glide than before.

The geometric characteristics of the guide 26, as well as an additional small roller, a support roller 40, in the rear region of the chilled food container 14 prevent the chilled food container 14 from tipping over in the forward position. If the chilled product container 14 begins to tip over, the rear roller of the chilled product container 14 is held onto the top wall of the guide 26 and, from that moment on, assumes the function of sliding or setting the direction. This combination of several rollers when extending the chilled product container 14 facilitates handling of the chilled product container 14 and reduces friction noise, which may also indicate abrasion.
