Description

The refrigerator

Refrigeration appliances such as refrigerators, freezers, fridge freezers or the like have shelves such as e.g. Abstellplatten, support plates, Abstellgitter or the like, on which the refrigerated goods is stored. A part or all shelves may be formed in particular as glass plates, on which at least front and back each profile part is placed. The front profile part protects the glass edge, the rear profile part can project upwards to prevent the goods to be cooled is pushed to the back side of the refrigeration appliance, this touches and freezes on it. In part, these shelves or shelves are drawer-like displaced or attached to the side walls of the refrigerators attached to ensure easier accessibility of the refrigerated goods.

It is known to realize these drawer-like extracts on telescopic extensions with metal rails. An example of this is described in DE 10 2006 018 203 A1. These telescopic extensions are of high quality but very expensive to manufacture. In the case of more cost-effective solutions, glass plates or plastic bottoms framed by plastic frames slip between groove-like receptacles on the side walls of the refrigeration appliances, which serve as guides for the plastic frames. However, this solution is quite difficult. In addition, these pull-out constructions seem too bulky in practice and take away a lot of space in the refrigeration unit.

The invention has for its object to perform a refrigerator with slidably mounted on the side walls, drawer-like extendable shelves, especially storage shelves, cost-effective, secure, discreet and easy to run.

The object is achieved according to the invention by a refrigeration device with the features of claim 1.

According to the invention, retaining projections are arranged substantially at the same height on the side walls, which are spaced apart from each other in the direction of the depth, which engage from below on the shelf and thereby support it and on which this is displaceable. Furthermore, the shelf at the edge has at least one guide element, which extends over only a partial length of the total depth of the inner container of the refrigerator and engages with the shelf inserted in a holding projection, in particular rear retaining projection. By the two edge-side guide elements on the shelf this is up and possibly also restricted downwards in its freedom of movement and thus a deflection of the shelf transversely, in particular perpendicular to its extension or displacement direction, ie folding it up when pulling at least over a predetermined extension area prevented. The at least two retaining projections arranged on opposite side walls of the refrigeration device can in particular be realized as very simple plastic parts and carry the shelf. About the respective guide element, which is preferably also realized as a simple plastic part, there is a restriction of the mobility of the shelf transversely, in particular perpendicularly, to its horizontal position on the holding projections and thus a positive guidance of the shelf to be pulled in the horizontal direction. By limiting the depth longitudinal extent of the respective retaining projection to only a small part of the total depth length of its associated side wall is made possible to make the side wall along a large part of its surface flat or planar surface. Thus, the shelf is neatly guided along its respective, edge-side guide element which extends only along a partial length of the total depth of the shelf, but not clamped edge along its entire depth. As a result, it is easily displaced, the risk of jamming is reduced and thus the risk of damaging the side wall. In addition, a side wall with (in the depth direction considered) shorter guide elements, in particular if it is flat or planar surface designed, easier to clean and visually appealing. Also, the entire interior of the refrigerator acts larger when the, emerging from the side wall retaining projections are smaller. The interaction of guide element on the shelf and retaining projection on the side wall of the refrigerator provides all the functionality that is sufficient for a pull-out shelf.

In particular, if the respective shelf along a front partial length of its total depth extension side edge free, ie without guide element, remains, and only borrowed along a rear part of a respective edge-side guide member is provided, as viewed from the front in frontal view results in an approximate Seitenenrahmenlose contour for the shelf. In particular, even if a cover strip has also been omitted at the front, transversely axial end edge of the shelf, the outer contour shape of the shelf as a whole appears frameless. This construction is particularly advantageous when a glass plate is used as a shelf.

Preferably, the respective guide element extends along at most half the total depth of the longitudinal side edge of the shelf.

According to an expedient development of the invention, the holding projections are preferably designed and arranged so that a shelf supported by you rests on at least two points that are more than half of the depth of the shelf apart. In addition, a breakpoint of the rear retaining projection is preferably arranged at a distance from the rear wall, which corresponds approximately to the depth of extension of the shelf. This ensures that the shelf is always well supported, even if it is pushed forward or backward, as long as it rests on the retaining projections.

In a particularly cost-effective manner and thus particularly advantageous embodiment, the retaining projections are tightened during deep drawing of the side walls of the refrigerator to this. As well as the brackets for most firmly positioned shelves these holding projections invention are easily mitgeformt in the production of the side walls; additional installation effort can be avoided. To make this possible, the retaining projections are in the form of a simple geometry, e.g. Crescent shape or partial circular disk shape constructed.

Preferably, the holding projections are formed like a curve; they stand out as cams from the side walls. This is contrary to the manufacturing process, there is no danger that thin spots occur, as they can occur in the formation of rectangular projections. Moreover, the curved structure of the projections simplifies the insertion of guide elements which are arranged on the shelf. are net. Preferred here is a crescent-shaped configuration of the cams. This is very easy to pull and also easy to clean.

Preferably, at least one holding projection on each side wall has a spacer arranged on the side wall, which projects upwards over the guide surface on which the shelf rests on the holding projection and thus prevents the shelf from direct contact with the side wall itself. As a result, the shelf slides when moving not on the entire side wall but only along the spacer, so it is easier to move than if it rubs on the entire side wall and beyond damaging the side wall can be prevented. The spacer may additionally perform the function to center the shelf and compensate for any existing Abstandseschräge the wall or other dimensional tolerances of the inner container of the refrigerated goods container of the refrigerator, and / or the respective shelf.

In an advantageous embodiment, guide rails are arranged laterally on the shelf, which preferably surround the respective associated holding projection, which carries the shelf, so that it slides along the guide rail during the displacement of the shelf. Preferably, the respective guide rail is only borrowed along a portion of the total length of its associated side edge of the shelf (viewed in the depth direction) attached thereto. In particular, the respective guide rail is provided only along a portion of the longitudinal side of the shelf in the depth direction, which lies in the rear region of the inner container of the refrigeration device, in particular household refrigeration appliance. In particular, it is expedient if only along a rear side edge section a guide rail is provided on the shelf as an enclosure, in which only the rear holding projection runs, ie is slidably mounted. Characterized in that preferably along a rear portion of the side edges of the shelf, a guide rail is provided, in which run along the rear holding projections on the side walls of the inner container in a horizontal extraction movement, the shelf is particularly advantageous against a rotational or tilting upward and secured at the bottom. Since a respective guide rail runs on the rear holding projections, a grinding and thus wearing of the retaining projections, which are preferably made of the same plastic material as the respective inner wall of the inner container are formed, largely avoided by the shelf itself. For the respective guide rail, a plastic material or a metal is preferably selected, which in particular has a low coefficient of friction. When using a glass plate as a shelf is thus avoided that this rand along the contact surfaces in direct contact with the rear holding projections on the support surfaces and wears it wears. Through the guide rails, especially if they are mounted in the rear side edge portion of the shelf, the shelf is guided in its extension movement so that he can not fold back to the rear, even if he is complaining Front or can fold down to the rear down when he complains the rear is. The guide rail is supported for this purpose on the underside of the retaining projection.

The length of the respective guide rail preferably corresponds at most approximately to the length by which the shelf in the extension direction can be moved forward. This ensures that the shelf is guided during the entire extension movement and is thus secured against tipping. For removal of the shelf is expediently raised to the front and top, so that the guide rail on the front retaining projection, in particular retaining cams, is lifted over and can be pulled out of the rear retaining projection, in particular retaining cams. Only then can the shelf be removed.

In a further preferred embodiment, two spaced guide rails are arranged on each side of the lateral, extending in the depth direction side edge of the shelf, each engaging in one of the retaining projections. By each running a guide rail on a rear and front retaining projection, wear of the retaining projections, which occurs in the friction of, for example, a glass plate on a plastic holding projection, can be largely prevented. The distance between the guide rails provides for easy removal of the shelf as it is extended by allowing the front holding projection in the removal position to pass through the gap between the spaced apart guide rails. This can be prevented that the shelf must be pulled completely to the front to remove. In addition, in a preferred embodiment, a preferably laterally arranged projection is attached to the shelf, which strikes on removal of the shelf from a stop element present on the refrigeration device, which is preferably realized in the holding projections themselves. By combining these very simple and inexpensive elements, the full functionality of a high quality drawer can be achieved with low production costs. A protrusion acting on the shelf as a stopper is arranged so that it strikes when pulling out of the shelf against a arranged on the refrigerator stop, preferably the holding projections themselves. Due to the interaction of these three EIA simple elements to be formed, holding projections, guide element and stop projection, a cost-effective, extendable shelf in a refrigerator can be realized, which prevents both the folding and falling out of the shelf during the extension movement and is easy to use.

In a preferred embodiment, the stop is located at the back of the shelf. When the shelf is fully extended, it abuts the respective holder projection, preferably the respective rear holding projection. This prevents the shelf from being extended beyond the point at which it rests stably on the holding projections and thereby tilts forward. Preferably, the rear stop is identical to the spacer bar, which is provided on the back of the shelf to prevent the stored on the shelf refrigerated material reaches the back of the refrigerator and freezes there. By this rear spacer rail is designed so that it can be used as a stop, can be dispensed with the attachment of a further additional stop. The rear spacer rail thus performs dual function.

In a further advantageous embodiment, the guide rail itself serves as a stop. For this purpose, the guide rail engages in the pull-out movement in the rearward holding projection, it reaches the front retaining projection until the extraction movement is completed. The guide rail does not release the rear retaining projection before it abuts against the front retaining projection. The front, so closer to the door lying retaining projection is preferably shaped differently than the rear, so that he does not like the rear in the guide rail can slide. The guide rail abuts against him and thus prevents too far forward pulling of the shelf and thus a tipping down the same. Thus, preferably, the spacers which keep the respective shelf such as a glass plate from the side wall, arranged on the front holding projections, while the rear holding projections have no such. The guide rails abut in this case on the front spacers, whereby they have a dual function, which makes the entire solution cheaper again. If the shelf is completely removed, it must be slightly raised at the front to move the guide rail over the stop and to be able to pull further forward so that it then releases the respective rear retaining projection.

Finally, it should be mentioned that it does not leave the scope of the invention if the entire guiding and holding elements of the extendable shelf not on the side wall of the refrigerator itself but on an acting as a side wall intermediate wall in the refrigerator, which, for example a wall formed by a shelf can be arranged.

Further details and advantages of the invention will become apparent from the subclaims in connection with the description of exemplary embodiments, which are explained in more detail with reference to drawings.

FIG. 2 shows the same as FIG. 1, but with the shelf pulled out to the front by a predeterminable pull-out section, FIG.

Fig. 3 shows the same as Fig.1 and 2, however, with the shelf during its removal, and Fig. 4 shows schematically as a detail of the shelf of Figures 1 with 3 together with one of its peripheral guide rails, which only along one

Part of the total depth of the shelf extends.

Elements with the same function and mode of action are shown in FIGS. 1 and 4, respectively provided the same reference numerals.

Fig. 1 shows a section of an inner container 18 of a refrigerator, on which the side walls 1 and 2, the rear wall 3 and a shelf 4 for parking refrigerated goods can be seen. Figure 4 shows schematically as a detail, the sliding suspension or storage of the shelf 4 along the depth extent of the left side wall 1. For the inner container 18, a plastic material is preferably selected, which allows the thermoforming during the manufacturing process. On the left, first side wall 1, viewed in the direction of the inner container 18, there is a front holding projection 5 and a rear holding projection 6, which are formed as drawn-out, curved projections during the production of the side wall 1. The front retaining projection 5 and the rear retaining projection 6 lie substantially on an imaginary horizontal connecting line which extends in the depth direction of the inner container 18. Symmetrically arranged on the right second side wall 2 are corresponding front and rear retaining projections 7 and 8. The two pairs of retaining projections 5/6, 7/8 are arranged substantially at the same height in the inner container. The retaining projections 5 - 8 carry the shelf 4, which rests on its top guide surfaces 9. The retaining projections 5-8 can preferably be integrally formed on the inner wall surfaces 1, 2 of the inner container 18 or be tightened in its thermoforming with. Alternatively, the retaining projections may also be attached as separate components at the desired height positions on the respective inner wall. In particular, the same plastic material as for the inner container can be selected for the holding projections. Alternatively, it may be used for a plastic material that is more durable and wear-resistant than the plastic material for the inner container for them. The retaining projections may be formed in particular by protruding cams or nubs on the respective side wall. Conveniently, they may have a crescent shape geometry shape. The respective holding projection is preferably dimensioned such that it occupies only a locally limited partial area of the total area of the side wall. Its longitudinal extent in the direction of the depth is limited to a small partial length of the total depth of the side wall. Preferably, the respective guide element extends along at most half the total depth of the longitudinal side edge of the shelf. In this way, the respective side wall can be broadly down to the location positions the retaining projections remain largely planar. In the area of the rear half of the shelf 4, a guide rail 10 and 1 1 are attached to this side only on the left and right side only along a side edge section. The guide rail 10 is fitted with an upper, U-shaped bar 12 on the shelf 4 and shows at the bottom of the shelf 4, a groove-like guide rail 13, in which the left, rear retaining projection 6 engages and along which the retaining projection 6 is guided as soon the shelf 4 is moved in the direction indicated by the arrow 17 horizontal extension direction. Similarly, the right, rear retaining projection 8 is guided in the associated guide rail 11 at the rear side edge portion portion of the shelf 4 and slidably mounted. At the back of the shelf 4 is a spacer bar 14 which keeps stored on the shelf 4 refrigerated goods away from the rear wall 3. The front retaining projections 5 and 7 have spacers 15 and 16, which protrude beyond the guide surface 9 and laterally engage the shelf 4 and keep it at a transverse distance to the side walls 1 and 2. In the insertion end position shown in FIG. 1, the shelf 4, which is preferably in the form of a glass plate, rests stably on the holding projections 5 - 8 and serves to receive refrigerated goods. The shelf 4 has at its transverse edge edge on a skirt 14 as end bar and spacer bar 14. This spacer bar 14 abuts in this insertion end position of Figure 1 to the rear wall of the inner container.

FIG. 2 again shows the same section of a refrigerator as in FIG. 1 with the two side walls 1 and 2 and the rear wall 3. In this illustration, however, the shelf 4 has already been moved along the direction of the arrow 17 by a predeterminable horizontal extension length into its pull-out end position. The guide rails 10 and 1 1 slide over the covered by them and therefore not visible in this figure rear retaining projections 6 and 8. The shelf 4 is so far moved forward until the guide rails 10 and 1 1 at the front holding projections. 5 and strike 7. In this position, the pull-out movement of the tray 4 is stopped before the guide rails 10 and 11 slide out of the rear holding projections 6 and 8, whereby the rear support points of the shelf 4 would be omitted and this would tilt forward. FIG. 3 again shows the same section of a refrigeration device, the view in this case being from the side, so that one looks into the corner formed from side wall 1 and rear wall 3. In this Fig. 3 shows how the shelf 4 moves beyond the extract end position and can be completely removed from the refrigerator to the front. For this purpose, the shelf 4 is slightly raised in its pull-end position in the front area, so that it moves along the direction of the arrow 19 and the guide rail 10 can be lifted over the front retaining projection 5 and pulled on this sliding forward. By lifting the front retaining projection 5, the guide rail 10 free, so that the shelf 4 can be pulled out of the refrigerator.
