The bearing angle has a parallel base plate (6a) arranged for the drag axis of the door with a screwing opening (5) and ridges on the back or on the inner side.

Description

The The invention relates to refrigeration device according to the preamble of claim 1.

Refrigeration appliances, in particular Domestic refrigerators such. Cooling or freezers, usually a chilled one Interior on the door of a door is closed, which is pivotable about a vertical axis. The Door is usually about so-called Bearing angle with the housing connected, which the cooled Interior encloses. The bearing angles are usually made of metal and with the housing screwed. To achieve the necessary stability, four Used screws.

at During installation, the bearing bracket is pre-assembled with a screw. Then he must be aligned and only then with the remaining three Screws finally be attached.

There Metal is relatively complex to process, is also the price for the today usual bearing journals correspondingly high. Also the assembly devours by the to be added Times for Pre-assembly, alignment and screwing a lot of time and is so also expensive.

Of the Invention is based on the object, a refrigeration appliance, in particular household refrigeration appliance in such a way that the Door to Closing it Interior above Bearing angle with the housing can be connected, both inexpensive to manufacture as well to be mounted.

Is solved the task according to the invention by a refrigeration device, in particular Household refrigeration appliance with the Features of claim 1.

The Have bearing angle of the refrigerator according to the invention a parallel to the pivot axis of the door arranged base plate. This base plate has at least one screw opening and in particular reinforcing ribs on her back and / or internally. Through the reinforcing ribs receives the base plate a stability, which allows a production made of plastic. This can be done the price for significantly reduce the bearing angles.

In a preferred embodiment is perpendicular to the base plate arranged a bearing arm for a journal. This bearing arm is firmly connected to the base plate. baseplate and bearing arm can so both made of plastic and injected as a plastic part become.

to support the bearing arm against the base plate is advantageously a stabilizer wedge intended. This stabilizer wedge ensures the vertical alignment between base plate and bearing arm and prevents this right angles changed under load.

Of the Bearing arm and the stabilizer wedge are advantageously designed as a hollow body. By this measure Material can be saved without the stability suffers.

at an advantageous embodiment also the bearing pin in one piece connected to the bearing arm. This is not an additional assembly step necessary for the production of the bearing angle. The bearing angle is produced in particular as a complete part by injection molding.

Especially advantageous in this embodiment the trunnion over star shape to its central longitudinal axis arranged ribs connected to the bearing arm. This way you can have a very material-saving and stable connection between the bearing arm and reach the journal. When a heavily loaded door arises a high pressure on the free end of the journal. Is the bearing angle one piece Made with the bearing pin made of plastic, can with frequent opening and Shut down the door an elevated one Wear on the Adjust bearing pin. Therefore, it is particularly advantageous on this free end of the journal provided a metal cap.

In a further preferred embodiment is at the back the base plate at a predetermined distance from the screw hole a perpendicular projecting spreader pin provided. With Help this Spreizstifts leaves the bearing angle can be easily pre-assembled. For this purpose will be the expansion pin pressed in a simple manner in a designated bore of the housing. For pre-assembly The bearing angle is therefore no longer necessary screw. This Saves material costs, but also simplifies the pre-assembly considerably.

In a further advantageous embodiment, a gap is formed in the free end of the spreader pin and the outer contour of the split portion takes the form of a double truncated cone. The largest diameter of the double truncated cone is designed slightly larger than the diameter of the bore. In this way, when pressing the expansion pin this slightly compressed and thus develops a clamping force with which presses the expansion pin against the inner wall of the hole. In this way, the bearing angle can only be fixed by the expansion pin so that it maintains the pre-assembled position at least without greater force. To fix the bearing angle must then only by the Screw a screw into another hole in the housing screwed hole. Thereafter, the expansion pin acts as anti-rotation for the bearing angle. The distance between screw hole and expansion pin is preferably dimensioned so that the forces acting on the bearing angle torsional forces can be well absorbed by the expansion pin.

In Advantageously, the reinforcing ribs have an annular rib around the screw hole. Because a lot of the forces, the act on the bearing angle, over the screw in the housing of the refrigerator initiated is the reinforcement the screw hole through the annular rib particularly important.

In a further advantageous embodiment are to the annular rib star shape directed to the outside reinforcing ribs tethered. These reinforcing ribs should prevent at higher Force the tearing rib rip off the base plate.

At the outer periphery the base plate can also advantageously a peripheral rib be provided. As a result, the star-shaped outward reinforcing ribs not only on the inside through the ring rib, but also on their outside captured by this edge rib. Ring rib, star-shaped after Outside directed strengthening ribs and edge rib provide a reinforcing profile in their connection, which perfectly stabilizes the base plate.

at a further advantageous embodiment can also be provided at the front of the base plate reinforcing ribs. Ideally are the reinforcing ribs on the front of the base plate according to the reinforcing ribs at the back the base plate shaped. This allows an even higher stability of the base plate to reach.

It it is not necessary that the journal is integral with the bearing angle is produced, but it can also be produced separately become. This becomes necessary when, for example, due to increased occurrence forces a more stable journal is required. Such a journal can be made of metal, for example. In this case, must an assembly step is carried out to produce the finished bearing angle. The bearing pin can, for example, at the bearing angle, over a Fastening or locking, to be fastened.

Around To avoid this assembly step, but could also the entire Bearing angle made of zinc die-cast.

As already described above, but is particularly plastic for the Production of the bearing angle. Very good results could be achieved with one fiber reinforced Thermoplastic can be achieved. By way of example, here is one with glass fibers offset polyamide can be called. Such a composite material is referred to as PA6 GF30, for example. Where PA6 stands for the polyamide and GF30 for a glass fiber content in height of 30 percent. Good results were also achieved with PA6 GF50. A corresponding composite is, for example, under the trade name Grivory available from EMS-Chemie.

Further Details and advantages of the invention and its developments emerge from the dependent claims in the context of the description of exemplary embodiments, which are based on the Drawings closer explained become.

It demonstrate:

1 a first view of an embodiment of an inventively constructed bearing angle for a household refrigeration appliance,

2 a further view of the embodiment according to 1 .

3 a second embodiment of a bearing bracket, and

4 another view of the embodiment according to 3 ,

In 1 and 2 is a bearing angle 1a represented, which was produced in one piece as a plastic injection molded part. The bearing angle 1a has a base plate 6a on, which runs parallel to the housing of the refrigerator in the mounted state. A connection plate 12 is connected to a longitudinal side of the base plate and aligned perpendicular thereto.

The bearing arm 14 is perpendicular to the base plate 6a , The connection plate 12 serves to stabilize the bearing arm 14 and the support within a plane perpendicular to the base plate 6a and parallel to the connection plate 12 , The connection plate 12 is therefore both with the bearing arm 14 as well as with the base plate 6a connected.

But also perpendicular to the plane of the connecting plate 12 becomes the bearing arm 14 against the base plate 6a supported. The stabilizer wedge is used for this purpose 15 maintaining the right angle between bearing arm 14 and base plate 6a Ensured in a plane perpendicular to the base plate 6a and perpendicular to the connection plate 12 is aligned.

Measures are still taken that provide a stable design of the bearing arm 14 effect yourself. So in its outer contour is the step 16 molded at high, on the bearing arm 14 heavy weight, can prevent kinking.

How out 2 will be apparent, are both the bearing arm 14 as well as the stabilizer wedge 15 formed as independent hollow body. The wall between the bearing arm 14 and the stabilizer wedge 15 shared by both cavities used as a boundary wall.

The base plate 6a is from a centrally located screw hole 5 breached. About this screw hole 5 becomes the bearing angle 1a attached to the housing of the refrigerator. For pre-assembly and to prevent rotation of the bearing bracket 1a is at a distance from the screw hole 5 at the bottom of the base plate 6a the expanding pin 4 intended. In the free end of the expansion pin, a gap is formed, so that the two resulting legs can be compressed. The outer contour of the split portion has the shape of a double truncated cone, wherein the free end of the smallest diameter of the Spreizstifts 4 having. This smallest diameter is designed to be slightly smaller than the diameter of the bore into which the expansion pin 4 is used.

The largest diameter of the double truncated cone is designed to be slightly larger than the diameter of this bore. In this way, the free end of the spreader pin can be 4 easily insert into the opening of the bore, while further impressions of Spreizstifts 4 this is compressed a bit. The expansion pin 4 develops over the compressed legs a clamping force, wherein the legs are pressed against the inner wall of the bore.

In this way, the bearing angle can be 1a only by pressing in the expansion pin 4 already fixed so that it retains, at least without major external force, the position set during pre-assembly. For final fixing of the bearing bracket 1a then only has to go through the screw hole 5 a screw are screwed into another hole in the housing of the refrigerator.

After completion of assembly, the expansion pin acts 4 as anti-rotation device for the bearing angle 1a , The distance between screw hole 5 and spreader pin 4 is dimensioned so that the forces acting on the bearing angle torsional forces by the expansion pin 4 can be well received.

The base plate 6a is reinforced with a variety of ribs on its back and / or inside. An important role is played by the ring rib 9 one who punched the screw 5 encloses. The ring rib 9 forms the connection between the screw head and the base plate 6 ,

With the ring rib 9 are the outward-pointing star ribs 10 connected. The outer finish of this back ribbing 7 forms a border rib 11 , in turn, with the star ribs 10 connected is. The back ribbing 7 is dimensioned so that the on the bearing arm 14 acting forces can be introduced into the housing of the refrigerator, thereby destroying the bearing angle 1a can be excluded.

The actual bearing for the door of the refrigerator is through the journal 2 educated. The journal 2 is with its one end with the bearing arm 14 connected. To create a stable connection as possible, is the bearing arm 14 with a torus 17 strengthened. The connection between the journal 2 on one side and the bearing arm 14 as well as the ring bulge 17 on the other side is through the connecting ribs 13 realized. These connecting ribs 13 run parallel to the central longitudinal axis of the journal 2 and are star-shaped on the outer circumference of the journal 2 arranged.

Through the on the bearing arm 14 attached ring bulge 17 can be the length of the connecting ribs 13 increases and thus the connection between the bearing arm 14 and journal 2 be strengthened. In this way, a very material-saving and stable connection between these two elements can be achieved.

Especially on the arranged under the door of the refrigerator storage angle 1a can act a high force. For example, a bottle door with a refrigerator door can reach a very high weight. This weight is fully loaded on the lower of the two bearing angles 1a with which the refrigerator door is attached to the housing. High forces act on the bearing 3 at the free end of the journal 2 a, in which the lower bearing of the refrigerator door rotates.

The depository 3 is therefore exposed to increased wear. For a quick wear of the bearing 3 To avoid, in a embodiment, not shown here, for example, a metal cap is provided, which is the free end of the journal 2 covers and forms the depository. This metal cap, for example, with a screw on the journal 2 be attached. But there is also the possibility of the metal cap and the journal 2 form so that the metal cap is only clipped.

In another, not shown embodiment, the entire bearing pin 2 made of metal. In this version, the bearing angle is generated without the bearing pin as an injection molded part. The journal is produced separately. The journal can then z. B. connected via locking elements with the bearing bracket.

at the embodiments shown here the entire bearing angle in one piece produced as an injection molded part. Very good results could with a fiber-reinforced Thermoplastic can be achieved. In particular, a glass fiber added polyamide composite has a very high abrasion resistance and elasticity. Such a composite material is referred to in general terms as, for example, PA6 GF30. there PA6 stands for the polyamide type and GF30 for a glass fiber content of 30 percent. But there were also already experiments with bearing angles successfully completed from PA6 GF50. Corresponding composites are for example under the trade name Grivory from EMS-Chemie available. Such a one-piece Construction of the entire bearing angle made of a fiber-reinforced thermoplastic allows the integration of all door bearing components in a single component, which is easy to manufacture and facilitates the assembly.

A different possibility for one-piece production The bearing angle is in a production of zinc die casting. Also with this material good results could be achieved.

That in the 3 and 4 shown embodiment of a bearing angle 1b differs from the embodiment of the 1 and 2 by an additional ribbing 8th on the front of the base plate 6b , Since all other elements are identical to the elements of the bearing angle 1a are, the same reference numerals have been used for this.

The front ribbing 8th of the bearing angle 1b also includes an annular rib 9 that the screw hole 5 surrounds the outward directed star ribs 10 and the edge rib 11 that the star ribs 10 connects together at their outer ends. The front ribbing 8th the base plate 6b is ideally designed as the rear ribbing 7 , As a result, the greatest strength can be achieved with the least amount of material.

The bearing angle 1a . 1b are shown here only in one version. Of course, these bearing angles are manufactured and mounted in one version for the upper and one version for the lower door connection. Both versions are symmetrical to each other and usable for both right and left-hinged doors.
