DESCRIPTION

Refrigerator, particularly domestic refrigerator

The invention relates to a refrigerator, particularly a domestic refrigerator according to claim 1.

Refrigerators according to the state of the art are divided many times into different temperature zones. Thus, for example, refrigerators are known that have a separate fresh maintenance compartment. This fresh maintenance compartment, in which vegetables and lettuces can be stored, should have a temperature just above the freezing point, so that items stored as far as possible remain fresh without, in this regard, be damaged

However, refrigerators have also been known to have their own freezing compartment in which

15 the temperature is below freezing point. In both the freezing compartment and the fresh maintenance compartment there is a lower temperature than in the remaining internal space. In both cases, these lower temperature regions are adequately separated from the remaining internal space. Thus, for example, the upper or lower region of the internal space can be separated with a compartment support with respect to the remaining internal space. However, there is also the possibility of separating the central region from the internal space with an upper and lower compartment support.

The front opening of the compartment that is produced in this way is usually closed with a lid. When you open the refrigerator door you have to open this lid separately to get access to the items

25 stored

However, it is relatively complex to install such separate compartments in the internal space of a refrigerator. Thus, on the side walls of the internal space there must be a possibility of fixing for at least one compartment support. Usually a rail-type bra is provided for this on the side wall.

It is also necessary to fix the axis of rotation for the cover on the side walls. Whenever this axis of rotation is in the lower edge of the lid, a lock that keeps the lid in its closed position must be provided additionally on the side walls. To install a compartment in the internal space of

A refrigerator may then be necessary up to three fasteners only in the anterior region of the internal space, which must be mounted on each side wall.

A refrigerator according to the preamble of claim 1 is disclosed in WO2006 / 120063 A1.

The invention is based on the objective of configuring a refrigerator, particularly a domestic refrigerator, according to claim 1 in such a way that the complexity for mounting a separate compartment in the internal space can be reduced and the amount of the fixing elements necessary for fixing.

The objective is solved according to the invention by means of a refrigerator, particularly a domestic refrigerator, with the features of claim 1. A construction piece is attached respectively to the inner walls of the internal space, in which both a support is provided for the cover as a support bracket. To perform these two functions, only a single piece of construction is needed for each side wall. Therefore, both material costs and assembly costs can be saved. The support for the support has a support rail, where a stop is provided in the front edge of the support rail. According to the invention, the support rail extends essentially in the direction of depth of the internal space.

In addition, a lock for the lid in its closed position is advantageously provided in the construction part. In this configuration, three functions can be carried out with the construction part for which

55 until now three construction pieces were necessary.

The lock is advantageously configured as a locking pin. This locking pin is molded into the construction piece and interacts with a locking opening in the lid.

65 preferably extend in the direction of depth of the internal space of the respective refrigerator compartment.

For the support of the lid, the construction part advantageously has a support arm. This support arm can also be molded directly with the construction piece. Preferably, the support arm has two parallel support branches. The separation of the two parallel support branches corresponds approximately to the thickness of the cover material in the region of the support. image2 Parallel support branches A support opening is provided in each support branch for housing a cap journal. In this case it may be a loose journal that is inserted through the support openings of the support branches and through a support opening in the cover during the assembly of the cover. Preferably, however, on each side wall of the lid a journal is molded which extends in both directions through the material.

5 of the side wall of the lid.

During assembly of the cover, only the support branches have to be slightly separated by pressing in this way, so that in the region of the support openings the gap is extended until the side wall of the cover with the caps fits between socks. The elasticity of the support branches reduces their

10 separation again to the original magnitude as soon as the plugs are in the support openings of the support branches. The cover is now rotatably fixed on the support branches.

Particularly advantageously, the support opening is configured with an oval shape in each support branch. Since the caps of the lid have a round cross-section, not only a 15-rotation movement of the lid is possible, but the lid obtains an additional degree of freedom in the direction of the larger diameter of the oval support opening.

Advantageously, the support opening is aligned in such a way that its larger diameter is oriented in a vertical direction. In this way a lifting and lowering movement of the lid is also possible on a limited scale. In this way, a very simple structured locking of the lid can be carried out. The locking opening in the lid has a hook-shaped extension for this purpose. During the closing and opening of the lid only the hook-shaped extension of the locking opening on the locking pin is raised. If the cover is then moved down again, the hook-shaped extension of the locking opening also descends and thus prevents the locking pin from leaving the opening of the

25 block

The support rail is molded directly to the construction piece and adopts approximately 90 ° with respect to the side wall of the internal space. The support that delimits the remaining internal space compartment can thus be easily placed on the support rail.

30 Particularly advantageously, the support for the support has an elastic or elastically applied treadmill on the construction piece. The treadmill essentially ensures that the support is unintentionally released from the holder. Therefore, the treadmill presses from above on the support and prevents it from rising from the support rail.

35 During assembly, the support is applied from above on the fastener, in such a way that the elastic or elastically fixed treadmill is pressed back. As soon as the support is supported on the support rail and the treadmill is released again from the lateral edge of the support, the elastic or elastically fixed treadmill moves back to its starting location. In case the support has to be removed, for example, for cleaning purposes, only

40 it is necessary to manually press the treadmill backwards, so that the support can be lifted upwards from the support rail.

In order to be able to mount the construction piece easily on the side wall of the internal space, several connecting pins are provided. To be able to mount the construction part with torsion resistance, more than one connection pin is required for the connection between the construction part and the side wall. The amount of the connecting pins depends on the load to be absorbed by the support.

Particularly advantageously, two connecting pins are connected in the upper region with the construction piece and inserted into openings in the lateral walls of the internal space. Torsion of the construction piece is safely prevented by means of the two connecting pins 50. The application of the connecting pins in the upper region of the construction piece ensures that with a load that acts on the support, the construction parts are pressed against the side walls and in this way a rollover of the construction piece is avoided . Since the connecting pins are only needed for fixing the construction pieces, they are fixedly connected to the construction part. If the construction part is not needed, with the

55 construction pieces are removed at the same time the connecting pins. Particularly advantageously, the entire construction part is made as a part with the locking pin, the clamp, the support arm and the connecting pins and is produced, for example, in the injection molding process.

The invention and its improvements as well as its advantages are explained in more detail below by means of drawings.

Further improvements of the invention are reproduced in the dependent claims. image4

They show schematically respectively: Figure 1, an exemplary embodiment of a construction piece constructed in accordance with the invention

with a support for a support and with a support as well as a lock for a cover, Figure 2, a side view of the construction part of Figure 1, Figure 3, the construction part of Figures 1, 2 fixed on the side wall of the inner space of a

5 refrigerator according to the invention, with cover mounted as well as with support inserted and Figure 4, an enlarged detailed view of construction piece, cover and support of the view of Figure 3.

The construction piece 1 shown in Figure 1 has a base body 2. In this base body 2 the support arm 3 is molded. The support arm 3 comprises the external support branch 4 and the internal support branch 5 . The lateral separation of the two support branches 4 and 5 corresponds approximately to the material thickness of the side wall 16 of the cover 14 (see Figure 4). The two support branches 4 and 5 have 6 oval support openings. The largest diameter of the oval support openings 6 is oriented in the vertical direction respectively. The support arm 3 extends in the installed state of the construction part 1 in the internal space of the refrigerator of Figure 3 essentially in depth direction as well as essentially

15 in parallel with respect to the two lateral walls of the internal space.

The locking pin 10 is molded on the external support branch 4. The blocking pin 10 adopts approximately 90 ° with respect to the external support branch 4. Its height is slightly greater than the separation between the two support branches 4 and 5.

In the internal support branch 5 a support rail 7 is placed, which extends in the direction of depth of the internal space approximately parallel with respect to its respective side wall. It serves as a holder for a support that delimits a separate compartment with respect to the internal space of the refrigerator. For this, it has an essentially flat support or sliding surface that has an essentially travel

25 perpendicular to the lateral wall of the internal space.

In the front edge of the support rail 7, the stop 8 is provided. This prevents the support, which supports the support rail 7 from being able to move forward. A backward movement is avoided by the rear wall of the refrigerator.

Above the support rail 7, the treadmill 9 is provided. The treadmill 9 is made of two branches, one of the ends of the longest branch being elastically connected with the base body 2. By elastic connection with the base body 2, the treadmill 9 can be introduced by pressure completely into an opening not indicated in more detail herein in the base body 2. In this way a

35 support on the support rail 7 and fix in this position.

From the representation in Figure 2 the two connecting pins 11 can also be obtained. Also the connecting pins 11 are molded directly into the base body 2. They are inserted into corresponding openings in the side wall of the refrigerator. By means of a support placed on the support rail 7, which presses the construction part 1 with its lateral edges against the side walls of the internal space of the refrigerator, the construction part 1 is fixed in this position. Only after removal of the support can the construction part 1 be picked up again from the side wall of the refrigerator if necessary.

In Figure 3 and Figure 4, the construction piece 1 is shown in the assembled state. On the wall

45 lateral 12 of the internal space of the refrigerator are provided two openings "not visible in this document" in which the connecting pins 11 are inserted. As a support a glass plate 13 was used in this case. The glass plate 13 is place during introduction on the treadmill 9 and press down. In this regard, the pisador 9 moves back until the glass plate 13 can pass thereto. Only when the edge of the glass plate 13 is placed on the support rail 7 can the pisador 9 be moved back to its original location and fix the glass plate 13 in this position. At the same time, now press the plate glass 13 against the construction piece 1 and thus prevents the connecting pins 11 from sliding out of the openings not visible herein in the side wall 12 of the internal space of the refrigerator.

To close the compartment also towards the front side of the refrigerator, cover 14 is provided.

The upper region has the handle 15, with whose help it can be operated. Laterally, the cover 14 is framed by its side walls 16, which extend in a location plane that extends in a direction of depth essentially parallel with respect to the side walls of the internal space. In these side walls 16 of the cover 14 there are plugs 19 that project to the same extent both on the inner side and the outer side of the side walls 16 of the cover 14 in the lateral direction, that is, essentially perpendicular to the plane of location of its side walls 16. The height of the pins 19 corresponds approximately to the material thickness of the outer and inner 4 supporting branches 4.

To be able to mount the cover 14, it is only necessary that the external and internal support branch 4 be separated by a minimum pressure, such that the side wall 16 with the journal 19 fits in the intermediate space 65. In order to continue simplifying this assembly process, the vanes 19 at their free end can be shaped slightly conical, such that the vanes 19 during the introduction between the two

image6

Support branches 4 and 5 extend their separation automatically by means of the conical bevel and the pressure exerted. As soon as the pins 19 have reached their final position in the support openings 6 of the support arm 3, the two support branches 4 and 5 are moved back to their original position and the pins 19 are surrounded by the openings of support 6.

5 To keep the lid 14 in its closed position, the locking pin 10 and the locking opening are provided

17. For closing the lid 14, it is pressed only in its handle 15 to the closed position. In this regard, the front side of the hook-shaped extension 18 rests on the locking pin 10. With additional pressure on the handle 15, the lid 14 is moved along a bevel on the extension 18 in the form of 10 hook slightly upwards, such that the hook-shaped extension 18 can slide over the locking pin 10. Then the lid 14 is lowered again and the hook-shaped extension 18 is behind the locking pin 10. In this position, the locking pin 10 can no longer slide out of the locking opening 17 and the cover 14 is secured in its closed position. The slight movement of the lid upwards during the pressure to the closed position is made possible by the support openings 6

15 oval, in which the pins 19 can not only rotate, but also offer them the possibility of moving together with the cover 14 up and down.

For opening the lid 14, it is slightly raised only in the handle 15. In this respect, the hook-shaped extension 18 is also raised and the locking pin 10 reaches the open region of the locking opening 20. In this position, the locking pin 10 is released and the cover 14 can be rotated around its sockets 19 to the open position.

If no separate compartment is needed in the refrigerator and the entire internal space has to be used as a temperature zone, the separate compartment can be easily removed. For this I know

25 extends only the separation of the two support branches 4 and 5 slightly, so that the cover 14 can be removed with its sockets 19. If the glass plate 13 is also to be removed, then the pins 9 are pressed in the direction to the side walls 12 of the internal space and the glass plate 13 can be lifted upwards from the support rails 7. After the removal of the glass plate 13, the construction pieces 1 of the side walls 12 of the internal space
