Description

The The invention relates to a household refrigerator and a door rack for a The refrigerator.

door racks are arranged on the inside of refrigerator doors, often one-piece made of plastic by injection molding and especially after opened up container for holding refrigerated goods. For example, a pleasing Appearance of the door compartment To realize the edge of the container with a frame or can be provided a decorative strip.

The The object of the invention is a door rack with a design frame or specify a decorative strip, which is relatively inexpensive can be.

The The object of the invention is achieved through a door rack for a Refrigerating appliance, having a Trim strip, which has a cross-sectionally U-shaped profile with inner surfaces, and one open at the top container with an edge on which the trim with its U-shaped profile is attached, wherein at least one of the inner surfaces at least partially is provided with a material of relatively high stiction, with the container is in contact and only due to its static friction, the trim on the container fixed.

One Another aspect of the invention relates to a household refrigerator with a a cold room delimiting body and a hinged on the body door for closing the Cold room, on the inside of which at least one inventive door compartment is arranged.

Of the Door racks according to the invention therefore comprises the container, the z. B. as such can already be used as a door rack, and the trim on the container is attached, in particular on the edge of the container is inserted. The trim strip may for example have the shape of a design frame and has at least partially a U-shaped Profile in cross section with the two inner surfaces on, of which at least an at least partially with the material of relatively high stiction is provided. This material is preferably relatively soft in the Compared to the material of the rest of the decorative strip and stands with the container in contact. Due to the static friction, therefore, there are prerequisites that the trim strip in the attached state firmly attached to the edge of the container is and thus can not slip or even unintentionally solve. This makes it possible that z. B. existing (storage) container for interior doors in refrigerators without additional Effort, such. As locking, gluing, welding, with new design framework or Moldings can be equipped. Joining the two Components, d. H. the (storage) container and the frame or the Decorative strip is realized by means of the possibly high stiction. The Stiction is inventively by that on the inner surfaces applied material of relatively high stiction, the for example, as a partially applied TPE strip as 2. Material component is executed on the base frame / trim strip. The base frame may consist in particular of conventional plastic and completely in the injection molding process have been produced. Through this technique it is possible without Tool change effort (Time and cost) or new tools existing door racks by a new one Change design or to supplement.

According to one embodiment the door rack according to the invention corresponds to the distance between the two inner surfaces in the Essentially the wall thickness the wall in the area of the edge. This results in a relative good grip of the trim strip on the container, which is reinforced by the material of relatively high stiction.

The Decorative strip may preferably be made of a material, which differs from the material of relatively high static friction. In particular, the trim strip can be made of plastic, which makes a relatively inexpensive Production of the trim strip allows becomes. Also the container can be made of plastic.

To A preferred variant of the door rack according to the invention is the material relatively high stiction a rubbery or a rubber-like Material. In particular TPE (thermoplastic elastomers) are special well suited.

The Material relatively high stiction z. B. glued to the inner surface or what a relatively simple production of the trim strip allowed to be attached by extrusion to the inner surface.

To an embodiment the door rack according to the invention The material of relatively high static friction extends substantially over the total depth of at least one of the inner surfaces of the cross-sectionally U-shaped profile the trim strip. This results in an improved grip of the trim strip on Container. The width of the material of relatively high stiction can be variable be designed and adapted according to the given conditions be.

Preferably, at least one of the inner surfaces of the trim strip can be provided with a recess, in particular with a groove which is filled with the material of relatively high static friction. This allows an improved hold of the material of relatively high static friction on the relevant inner surface light.

It is possible, only one of the two inner surfaces the trim strip with the material to provide relatively high stiction. To better fix the trim on the container are after a preferred embodiment the door rack according to the invention both inner surfaces at least partially provided with the material of relatively high static friction.

For one again improved hold of the trim strip on the container, those areas of the both inner surfaces, which are provided with the material of relatively high stiction, are opposite.

Around For example, tolerances of the wall thickness of the container and / or the distance between the two inner surfaces At least partially offset with the container in Contact standing surface the material of relatively high stiction, in particular be provided with fins or ribs, in particular vertically run.

ever according to embodiment the door rack according to the invention is on at least one of the inner sides or inner surfaces of the Design frame or the trim strip applied a second, soft component, which has a relatively high coefficient of friction. At least one of the pages can additionally slats have to compensate for tolerances. This makes it possible that when pressing the Frame or the trim strip on the existing container, the especially as such can represent a door rack, the trim strip or the frame on the container without further additives liable. It is also possible, only one side (inside or outside) the storage rack or the trim strip with the soft component equip. This reduces the friction, but depending on the application this may already be enough.

Of the Door racks according to the invention can depending on the embodiment offer the following advantages: Complexity reduction, cost savings by using existing storage containers with new design-specific Components, no gluing the trim strip to container required, relatively easy to assemble and disassemble without damaging the door compartment, reliable, since it can be produced fully automatically, tolerance compensation by TPE-slats between door racks and frames (components can be used in different cavities are produced, resulting in a relatively large tolerance width results.)

One embodiment The invention is exemplified in the accompanying schematic drawings shown. Show it:

4 the trim strip and

5 and 6 Detailed views of the trim strip.

The 1 shows a freezer-refrigerator combination 1 as an example of a household refrigerator in a perspective view. In the case of the present embodiment, the freeze-refrigeration combination 1 a body or a housing 2 with a back wall 3 , two side walls 4 and a partition 5 inside, inside a freezer compartment 6 and a fridge 7 are arranged. The freezer compartment 6 is from the fridge 7 through the partition 5 separated. The freezer-fridge combination 1 further includes one on the housing 2 battered door 8th for closing the freezer compartment 6 and one on the case 2 battered door 9 for closing the refrigerator 7 ,

In the fridge 7 are several storage shelves 10 arranged on which refrigerated goods can be stored. The freezer-fridge combination 1 also has a in the lower part of the refrigerator 7 arranged vegetable dish 11 on. The freezer-fridge combination 1 also has a temperature selector 12 with interior lighting on, with which the set temperature of the refrigerator 7 and the freezer compartment 6 can be adjusted.

On the inside of the door 9 are door racks 13 to 15 arranged, of which, for example, the door rack 14 in the 2 is shown in more detail. The door racks 13 . 14 can be similar to the door rack 14 be educated.

In the case of the present embodiment, the door rack 14 an open-topped container 21 on whose top view in the 3 is shown. The container 21 was z. B. made of plastic in particular in one piece by injection molding and has a front wall 22 , a back wall 23 , two side walls 24 and a floor 25 on. The container 21 is designed to be in a generally known manner to the inside of the door 9 can be attached. Furthermore, the container 21 be designed such that he can already form as such a door rack.

In the case of the present embodiment, the door rack 14 a U-shaped design frame or a U-shaped trim strip 26 on, for example, made in one piece by injection molding of plastic has been. The trim strip 26 is in the 4 shown closer and is on the side walls 24 and the front wall 22 formed edge 27 of the container 21 attached or is at least partially over the edge 27 slipped. In the attached or slipped state thus forms the trim 26 at least part of the edge of the opening of the entire trot 14 , The area of the trim strip 26 standing on the front wall 22 of the container 21 is plugged is with the reference numeral 28 and the areas of the trim strip 26 on the two side walls 24 of the container 21 are plugged are with the reference number 29 Mistake.

As it is from the 5 and 6 it can be seen has, in the case of the present embodiment, the trim strip 26 in cross-section a U-shaped profile and comprises substantially two mutually parallel U-shaped walls 30 . 31 that with a substantially U-shaped and to the walls 30 . 31 right-angled connecting wall 32 are connected. The two walls 30 . 31 thus form a gap with a gap width b and a depth t. The gap width b corresponds approximately to the wall thickness of the side walls 24 or the front wall 22 ,

In the attached state of the trim strip 26 are the front wall 22 and the side walls 24 in the area of the edge 27 of the container 21 on both sides of the inner surfaces 33 . 34 the walls 30 . 31 the trim strip 26 facing or even touching them. The inner surface 35 the connecting wall 32 lies on the edge 27 of the container 21 on.

In the case of the present embodiment are in the inner surfaces 33 . 34 in the fields of 29 the trim strip 26 that go over the side walls 24 inverted, depressions or grooves 36 admitted. The grooves 36 have a width B, for example, extend over the entire depth t of the walls 30 . 31 the trim strip 26 formed gap and can be approximately centered with respect to the depth of the door compartment 14 in the inner surfaces 33 . 34 be arranged.

The grooves 36 are in the case of the present embodiment with a rubbery or rubber-like material 37 filled, which is relatively soft and ensures a relatively high stiction. The trim strip 26 lies with her rubbery or rubber-like material 37 on the side walls 24 of the container 21 on, ie the rubbery or rubber-like material 37 stands with the side walls 24 in the area of the edge 27 of the container 21 with the container 21 in contact.

In the case of the present embodiment, the material is 37 TPE, in particular TPES. The grooves 38 were with the rubbery or rubber-like material 37 z. B. injected by extrusion. The rubbery or rubber-like material 37 but can also be otherwise on the inner surfaces 33 . 34 be fastened, such. B. by gluing.

If the trim strip 26 on the edge 27 of the container 21 stuck, is the rubbery or rubber-like material 37 with the side walls 24 in contact on both sides. Due to the relatively high stiction of the rubbery or rubbery material 37 is the decorative strip 26 on the container 21 fixed without further action.

To tolerances of the gap width b and / or the wall thickness in particular of the side walls 24 at least partially offset, is at least the surface 38 of the rubbery or rubber-like material 37 that with the side walls 24 of the container 21 is in contact, roughened or points in the direction of the depth of the gap, ie vertically extending, fins or ribs 39 on.

In the case of the present embodiment, the inner surfaces 33 . 34 both sides each in the areas 29 the trim strip 26 with the rubbery or rubber-like material 37 provided, in particular the rubber-like or rubber-like materials 37 are arranged opposite one another. But it is also possible that only one of the inner surfaces 33 . 34 with the rubbery or rubber-like material 37 is provided or that also or alternatively in the area 28 the trim strip 26 at least one of the inner surfaces 33 . 34 with a rubbery or rubber-like material 37 is provided.
