EP 2 159 523 A1 describes a kitchen refrigeration apparatus, which has a system of consoles, which is configured to couple a drawer of refrigerated product to side slots of an inner container of the kitchen refrigeration apparatus. The console system has two opposite side pieces. Each side piece has a fixing piece, to be able to fix the side piece in the groove and it has a sliding rail, to accommodate the drawer of refrigerated product in a removable way in the side piece. For the formation of a side piece, the fixing part and the slide rail are connected through separate fixing means, such as screws. EP 2 159 523 A1 publishes a refrigeration apparatus according to the preamble of claim 1.

Document DE 20 2004 017 136 U1 describes a telescopic rail system, in particular for refrigeration appliances and / or freezers, with a support plate for the fixing support of the telescopic rail system in the inner container of the refrigeration apparatus and / or the freezing apparatus and two telescopic rails arranged facing each other on the support plate in their lateral zones. The telescopic rails can be arranged in this case on a surface of the support plate.

The purpose of the invention is to create a fixing support for tray bottoms in refrigeration apparatus, through which one or more tray bottoms can be easily removed.

This task is solved by means of a refrigeration apparatus, in particular domestic refrigeration apparatus, which has a thermally insulated inner container, which forms a storage space for refrigerated product, at least one tray bottom for the placement of refrigerated product, as well as at least two retention slots placed opposite in the inner container for the bottom of the tray, as well as having a support rail with a fixing section, which is configured for insertion in the retention slot, to retain the rail of support in the inner container, and with a guide section, which is configured for movable conduction of the tray bottom, to accommodate the tray bottom in the removable housing space, in which the support rail is configured as rigid individual component, which has an angular profile, in which a first angular arm of the support rail fo The guide section and a second angular arm form the fixing section, the support rail presents for the formation of a transition or press fit between the fixing section and the retention groove a fixing section, whose contour is adapted to the internal dimensions of the retention groove.

The support rails are configured in this case as rigid individual components. The support rails can be configured to be inserted through a user in retention slots, which are present in inner side walls of the inner container. In particular, the support rails can be configured so that they can be inserted into support slots, which are configured for immediate retention of edges of a tray bottom.

By means of the support rails according to the invention, for example, refrigeration apparatus can also be retrofitted, which in themselves were only configured to receive, that is, retain tray bottoms directly on their side edges in the inner container. Thus, by means of the support rails according to the invention, one or more tray bottoms can be guided removably into the inner container and / or other tray bottoms can be accommodated without using the support rails directly. in the retention slots.

The support rail for the formation of a transition or press fit between the fixing section and the retention groove a fixing section, the contour of which is adapted to the internal dimensions of the retention groove. Thus, for example, a user can manually reliably fix the support rails on the inner sides of the inner container without the use of tools. The support rails can be configured in this case so that they can be detachably fixed in the retention slots, so that a user can, if necessary, remove the support rails outside the cooling apparatus and, in

concrete, especially without needing tools for it.

In all embodiments according to the invention, the support rail may have a retaining means, to retain the support rail in the retention slot in positive and / or frictional joint. In a special embodiment, the support rail may have a retaining means, which is configured to retain the support rail in positive connection in the retention slot. The retention means can serve to securely retain the support rail in the respective retention slot. The retention means may be configured to be activated or manually released.

The retention groove may have a rear projection, in which a projection of the retention means in a position of the fixing section fixed in the retention groove fits positively. Through a combination of rear projection and projection, a positive connection is created. The support rail according to the invention is secured in a positive manner by means of the positive connection in the inner container or in its inner wall against unforeseen release.

In all embodiments according to the invention, the support rail has a stop, which is configured to limit a maximum extraction length of the tray bottom. By limiting the maximum length of extraction of the tray bottom, a fall and / or tilting of the tray bottom outside the refrigeration apparatus is prevented. In this way, the refrigerated product stored on the bottom of the tray remains stable and the danger of a fall is reduced.

The stop can be formed by a projection on a lower wall of the support rail, on which a edge section of the tray bottom (8) is supported at the maximum extraction length of the tray bottom. Depending on the depth of the tray bottom, the section of the bottoms of the tray bottom can be arranged in such a way that only a predetermined non-critical part, for example at most half of the depth, of the bottom of the bottom can be drawn the tray outside the refrigeration appliance.

In all embodiments according to the invention, the support rail has an angular profile. The angular profile can form a rectangular L-shaped profile in the cross section. In all embodiments according to the invention, the support rail in this case has a first angular arm, which forms the guide section and has a second angular arm, which forms the fixing section. The guide section of the first angular arm may be specially configured as a rib.

In all embodiments according to the invention, the guide section may have a rib that extends in a horizontal direction and at least approximately parallel to a side wall of the inner container and predetermines an extraction direction. The rib in this case forms a guide, which can predetermine the direction of extraction and the angle of extraction.

In all embodiments according to the invention, the tray bottom may have a ribbon that surrounds the guide section, in particular the rib, especially from above, in particular a plastic strip. A removable housing free of play for the tray bottom can be created through a surrounding housing of the tray bottom, for example, on one or two support rails.

In all embodiments according to the invention, the support strip, in particular the guide section, has a roller, in particular a roller housed rotatably, which rolls along a guide path of the bottom of tray. Since the tray bottom is guided through a guide section in the support strip on the roller, which can be rotatably housed, by means of rolling friction, removal and insertion of the tray bottom is easily possible with reduced force expenditure, that is, by a user.

The guide path may be arranged in a hollow profile of the tray bottom. Since the guide path is arranged in a hollow profile of the tray bottom, both the guide path and optionally the roller can also be protected against dirt ingress. Alternatively or in a complementary manner, the tray bottom can be removed and inserted with driving safety, since through the guide path arranged in a hollow profile of the tray bottom a protection against fit is created, which shields the roller against Contact.

The bottom of the tray can have a glass plate, on which the strip is fixed directly, in particular the plastic strip. The slat can be arranged circlingly on an outer contour of the tray bottom. In particular, the plastic strip can be injection molded, adhered, in particular held or glued to the outer edges of the glass plate.

The slat, in particular the plastic slat, can be connected to a rear retaining wall of refrigerated product, which extends in the form of a frame around the bottom of the tray (8), in particular the glass plate and which extends from the tray bottom plane, in particular from the glass plate plane up.

In summary and represented in other words, in this way it results through the invention, among other things, a refrigeration apparatus, which is configured with removable planes, ie tray bottoms. By means of the support rails according to the invention, a prefabricated extraction system can be dispensed with. In particular, in price segments, which do not allow the use of solid extraction systems, the support rails according to the invention can be used in a cost-optimized manner.

An extraction system according to the invention for tray bottoms, in particular tray bottoms in the form of boards, may be constituted by a glass tray bottom surrounded by injection, in particular with raised edges. An extraction system according to the invention can have two support strips, which can be inserted, for example, laterally into the frame of the glass plate.

The frame forms the guide for these support slats, the extraction path may be limited on retention projections or stops. The support slats and the tray bottom can thus form a construction group, which can be converted without problems, for example, into a field of sidewall ribs, that is, several overlapping retained grooves, in particular on opposite side walls of the inner container and can be varied in height position.

The slats in this case rest in slit type housings in the refrigerated product container.

The support slats can be fixed by means of an injection molded retention spring in the inner container. The slats could be designed as injection molded parts that can be manufactured in a favorable manner. The bottom of the tray can be a glass plate surrounded by injection. The two rails mean, in effect, an extra cost overrun of this removable system compared to a fixed fixing of the tray bottoms. This solution is especially suitable also for economic devices and construction series.

The extraction path, which makes this simple system possible, is completely sufficient to considerably facilitate access to stored refrigerated products. An optionally raised edge of these extractions can separate the refrigerated product clearly from the inner wall. Such separation prevents the refrigerated product from touching the walls of the container and moving through the extraction movement and can fall.

Other advantages result from the following description of an exemplary embodiment with reference to the attached figures. In this case:

storage space 3 and is pivotally housed therein relative to an opening plane of the domestic refrigeration apparatus 1 or of the inner container 4.

The inner container 4 has retention slots 7 for at least one tray bottom 8. Instead of an individual tray bottom 8, two or more tray bottoms 8 can also be housed in the inner container 4. In the inner container 4 they can have on the two side walls 4a, 4b opposite each other, respectively, one or more retention grooves 7. The at least one retention groove 7 has at least one support surface 7a pointing upwards and one support surface 7b that points down.

One or more retention grooves 7 collaborate with a fixing section 12 (Figure 2) of a support rail 9 according to the invention, which houses the bottom of tray 8 in a position of desired height in the inner container 4. The Support rail 9 is coupled to the bottom of tray 8, housed in a movable way for removal. The retention grooves 7 are arranged on opposite side walls 4a, 4b of the inner container 4, in particular stepwise in various height positions, as shown in Figure 1.

As shown in FIG. 2, the support rail 9 presents a fixing section 12 for the formation of a transition or press fit between the fixing section 12 and the retention slot 7, the contour of which is adapted to the measurements interiors of the retaining groove 7. The fixing section 12 has a basic parallelepiped shape. At a front end 9a, rear in the refrigeration apparatus 1, that is to say that it must be positioned in the deep position in the inner container 4, the semi-circular profiled fixing section 12 is configured in the cross section. The fixing section 12 has, in addition, two upper and lower sides 12a, 12b at a distance parallel to each other and overlapping. At a front end 9b on the front side in the refrigeration apparatus 1, that is, it must be positioned in the most advanced position on the side of the door in the inner container 4, the fixing section 12 has a projection 15, in Particularly a spring projection, which fits in a position of the support rail 9 fixed in the retention groove 7, in a rear shoulder 16 (Figure 1) in an inner wall of the retention groove 7. The projection 15 and the projection rear 16 in this respect form a retention means, which retains the support rail in positive connection in the retention slot 7. The retention means or the projection 15 and the rear shoulder 16 can be arranged especially on side walls 4a and 4b opposite the inner container 4 or opposite sides of the tray bottom 8 and in this respect are arranged symmetrically in pairs.

The support rail 9 has the guide section 14. The guide section 14 extends horizontally and in a position mounted parallel to one of the side walls 4a, 4b of the inner container 4. The guide section 14 has a rib 14a which predetermines the extraction address. The bottom of tray 8 has a strip 17, in particular a plastic strip 17a.

The support rail 9 forms, as shown in Figure 2, in the exemplary embodiment an angular profile. The angular profile can be especially an L-shaped profile, at right angles in the cross section. In all embodiments, the support rail 9 may in this case have a first angular arm, which forms the guide section 14 and a second angular arm, which forms the fixing section 12. The guide section 14 of the first Angular arm can be specially configured by the rib 14a.

As shown in Figure 3, the strip 17, in particular the plastic strip 17a of the tray bottom 8 embraces the guide section 14 or the rib 14a from above. The strip 17, in particular the plastic strip 17a, has a U-shaped cross section for this purpose, comprising the guide section 14 or the rib 14a from three sides. In the cross section of the support rail, the guide section 14 is arranged at a right angle with respect to the fixing section 12. On an inner edge between the guide section 14 and the fixing section 12 in the embodiment example A longitudinal notch 18 (FIG. 2) is shown, in which a retaining slat section 19 of the slat 17, in particular of the plastic slat 17a, which extends bent, can fit in a positive connection.

In the embodiment example, the tray phone 8 has a glass plate 20, in which the strip 17 is fixed, in particular the plastic strip 17a. The glass plate 20 may be surrounded by injection by the strip 17, in particular by the plastic strip 17a. The strip 17, in particular the plastic strip 17a, can therefore be connected to a rear retaining wall of refrigerated product 21 that surrounds the bottom of the tray 8 in a frame, in particular the glass plate 20, and that it extends from the plane of the tray bottom 8, in particular from the plane of the glass plate 20 upwards.
