Description

The present invention relates to a refrigerator, comprising a body with an inner container, which forms a cooling space and a storage plate for refrigerated goods, which is mounted extendable in the cooling chamber on linear guides.

A generic refrigerator is in DE 10 2006 018 203 A1 described. The local shelf for a refrigerator has a frame and a bordered in the frame carrier plate. The frame is assembled from Extrusionsprofilstücken and ends of the extrusion profile pieces connecting profile parts. To make the shelf easily removable, it is supported by telescopic extensions. For this purpose, the extrusion profile pieces in cross-section on a vertical and a horizontal leg, and a telescopic extension is hidden in a spanned by the two legs angle of each extrusion profile piece added. The support plate may in particular be a glass plate, or else a grid with a peripheral frame and two struts connecting to opposite sides of the frame. In such a grid, the ends of the struts are preferably connected frontally to the frame. The backing plate is supported by two lateral opposed extrusion profile pieces. The extrusion profile pieces also extend above the carrier plate. Depending on a vertical and a horizontal leg of each extrusion profile piece forms an angle in each of which a telescopic extension is added. By extending beyond the plane of the support plate upwardly extending portions of the extrusion profile pieces, the storage space is reduced to the support plate.

The object of the invention is to provide a refrigeration device with increased capacity for refrigerated goods. In particular, the customer benefit in a rail on. Linear guides and preferably telescopic extensions mounted, extendable support plate can be improved.

The object is achieved by a refrigeration device, in particular domestic refrigeration appliance, comprising a body with an inner container which lines a cold room and at least one storage tray for refrigerated goods, the extendable in the refrigerator by linear guides on Inner walls of the inner container is supported, characterized in that the linear guides comprise supports, which engage under the storage shelf and at least a flat plate portion of the storage shelf, the support is overlapping introduced to the inner walls of the inner container.

By having the linear guides support, which engage under the storage tray and at least a flat plate portion of the storage plate the support overlapping is brought to the inner walls of the inner container, which can be used for parking of refrigerated good surface on the storage tray.

The extendable shelves used in refrigerators are mainly designed as trays or baskets. The drawer-like pulling out and pushing in of the shells or baskets extracts used in particular telescopic extensions are usually arranged on the left and right side of the shell or basket. So is the shell or the basket between two extracts. As a result, the usable area in the shell or in the basket is reduced by the width dimension of the lateral pull-outs. Due to the existing in the extendable shell or in the basket side walls, it is possible to use the located directly above the extracts tray volume, in which the side walls above the side extensions is widened accordingly in width. However, if instead of a shell or a basket, an extendable flat plate are provided, so there are unusable areas on the extracts when the flat plate is arranged at the same height between the extracts. Although the user could load the volume directly above the extracts with refrigerated goods. When pulling out the flat plate without side walls, however, the refrigerated goods would fall laterally from the extension plate. According to the invention, therefore, an arrangement of a flat extension plate at the same height between the two extracts by an arrangement of the flat extension plate above. replaced over the extracts.

Under linear guides all types of bearings are understood that are suitable to bring the storage tray from a storage position in which the storage tray is inserted into the refrigerator so that the door of the refrigerator can be closed in a removal position in which the storage tray when open Door of the refrigerator is positioned at least partially offset to the user. In general, the linear guides can be telescopic extensions, ie displaceable along a distance Bearings, which consist of several telescoping parts, such as rails, strips or pipes. One type of such a telescopic extension is, for example, in the DE 10 2006 018 203 A1 shown. Known manner, however, linear guides can be formed in the simplest case of grooves on the inner walls of the inner container. In these grooves, the opposite lateral edge portions of the storage tray could be used. However, the invention is not concerned with linear guides in which the grooves jump back from the plane of the inner walls of the inner container, since there does not pose the problem of a reduced storage space. The invention is concerned only with embodiments which have telescopic extensions. With regard to all variants of the invention, it is crucial that a reduced due to telescopic extensions shelves is increased again that the flat storage tray is designed such that it extends over the supports, which engage under the shelf away as close as possible to the inner walls of the inner container zoom ,

The flat storage tray according to the invention is constructed so that the footprint of the storage tray is not located between the two extracts, but above the extracts. As a result, a footprint in full width of the inner container of the refrigerator can be realized. Refrigerated goods can thus always be stored directly on the storage tray and not on an extract. Even if it is loaded very close to the container wall of the refrigerator. The volume located below the storage tray between the two drawers can then be used to store the goods to be refrigerated, which stands or lies on an underlying second storage tray or tray. Alternatively or additionally, therefore, the space between the two extracts can also be used for the storage of a removable shell.

The at least one flat plate portion of the storage tray can be brought up leaving only a slight gap to the inner walls of the inner container. In all variants of the invention, therefore, the planar storage tray, leaving only a gap extending in the direction of the inner walls of the inner container. A slight gap is required in order to be able to freely pull out and insert the storage tray without the side edges of the storage tray or the carrying slats rubbing against the inner walls of the inner container.

The storage tray can be completely flat. Alternatively, the storage tray may have at least two planar plate sections, each of which is associated with a plate portion of the linear guides adjacent. Thus, the flat plate sections may each be formed extending at least over one third of the total width of the storage plate.

The supports may be sections of the linear guides projecting from the inner walls of the inner container into the cooling space. Telescopic extensions generally have holders for the storage shelves to be removed. These holders can be formed by sections of movable guide rails of the telescopic extensions, which are firmly connected to the storage tray.

In this case, the storage tray may be connected to support strips, which form the supports and are connected to the movable guide rails of the linear guides. The support strips thus form connecting elements to connect the movable guide rails firmly to the storage tray. It should be noted that the support bars could be cause, which would reduce the usable storage space on the storage tray. Therefore, the position of the support strips is to be chosen according to the invention so that the support strips i. the supports engage under the newly formed storage tray.

Preferably, the support strips at least flush to the side edges of the storage tray out open, arranged below the storage tray recording, within which the linear guides are at least largely, in particular taken such that they are flush with the free, directed away from the storage shelf edges. A recessed arrangement of the linear guides in the receptacle is conceivable.

Advantageously, the support strips and the receptacles are integrally connected, in particular einstoffig each other.

In particular, the storage tray can be positively connected to the support bars. As a result, for example, to dispense with separate fasteners, which is the number of parts reduces, simplifies assembly and makes the production more cost-effective. For this purpose, the support bar may be formed such that it laterally surrounds the edge portions of the storage tray, so that the storage tray is held in a groove-like recess of the support bar.

Preferably, in this case, the storage tray may be inserted at two opposite lateral edges in receiving grooves of the support strips, which are arranged above the linear guides. In this case, the support strip comprises the lateral edges of the storage tray only by means of a thin wall of the support bar, so that further the maximum possible footprint on the storage tray in full width of the inner container of the refrigerator can be used.

Also, two opposite, extending from the flat Abstellplatte down first support strip portions limit a receiving space for at least one removable Kühlgutschale. The support strips are used function unifying by the support bars not only form a support for the movable guide rails and the storage tray, but also a holder for a hanging storage of refrigerated goods. Thus, the carrier plate sections extending downwardly from the flat storage tray may have holders for a suspended storage of the refrigerated goods tray. The holders are connected to the support strips or can be formed integrally with these. The holders may be configured as usual, i. they may be formed, for example, by angular strips extending along the length of the support strips or they may, for example, be formed by grooves which are made in side walls of the support strips and engage in the edge portions of the refrigerated goods.

Removable refrigerated trays in refrigerators are previously inserted into an additional support frame. This support frame is hung under a solid shelf and surrounds the shelf from the front and back. With the invention, a space for removable Kühlgutschalen is created between the two side support strips under the flat storage tray. This means that a receiving contour of the removable tray is now placed laterally in the area of the trays. This results in the possibility to dispense with an additional elaborate support frame and instead to use the existing support strips of the storage tray or the extracts or to expand it as a holder for the refrigerated goods.

In a storage tray, which is located at the lowest point in the refrigerator, the capacity for refrigerated goods is thereby further increased that the refrigerated goods are not stored on separate holders of the support strips hanging, but under the storage directly on the floor of the refrigerator or the refrigerator be turned off.

Thus, according to the invention, a pull-out plate with optimum footprint width is placed at the very bottom of the device, and the combination with pushed-removable cold tray be chosen because the underlying space is too low to store useful refrigerated goods therein. In this special case, it is also possible to put the removable Kühlgutschale on the container bottom and not suspend. Furthermore, even in this special case, a large housing-deep refrigerated goods can be replaced by several smaller housing-deep refrigerated goods shells, which are also placed on the container bottom. By simply setting the removable Kühlgutschalen on the container bottom no additional holder on the extension plate or separate fasteners to the extracts are needed, creating a very cost-effective solution.

According to another aspect of the invention, two opposing second support bar sections extending upwardly from the planar storage shelf may form part of a fall arrest barrier. For this purpose, the fall protection barrier may comprise at least one wire bow section, which is arranged at a distance to the top of the storage plate extending parallel to this.

The variants of the flat pull-out plates according to the invention allow the user optimal use of the refrigerator volume. The combination of flat extension plates and underlying removable refrigerated goods shells allows a cost-effective solution with high customer benefit, in particular with regard to the capacity for refrigerated goods.

Different embodiments of the invention are based on a in the FIG. 1 exemplified refrigeration appliance for household purposes and on the hand in the FIGS. 2 to 6 Shelf plates and support strips shown, as well as Kühlgutschalen described. Out The detailed description of these specific embodiments also result in further general features and advantages of the present invention.

In the illustrated embodiment of the linear guide 11b as a telescopic extension, the linear guide 11b next to the fixed guide rail 16, a movable guide rail 17 and an intermediate rail 18. The intermediate rail 18 can both with respect to the fixed guide rail 16 and the movable guide rail 17 to be slidably mounted by means of bearing balls. In a simplified embodiment eliminates the intermediate rail 18. Then, the movable guide rail 17 is mounted directly relative to the fixed guide rail 16, for example. Sliding bearing ball.

The movable guide rail 17 is fixedly connected to a support bar 19. The support bar 19 has a vertically extending wall portion 20. In a lying below the plane of the storage tray 8 region of the vertically extending wall portion 20, the support bar 19 is formed as a box-shaped hollow profile strip 21. The support bar 19 has an inventive support 12, on which the storage shelf 8 rests with a flat portion. The flat portion of the storage tray 8 is used up to the lateral inner wall 10 of the inner container 3. Only a slight gap can remain. In this gap, a portion support bar 19 may extend upward to support a simsförmigen wall projection 22 and a tubular receptacle 24. The storage tray 8 sits on the top surface of the box-shaped hollow profile strip 21. The storage tray 8 is fixed on its upper side by the simsförmigen wall projection 22. In other words, the top surface of the box-shaped hollow profile strip 21 forms together with the simsförmigen wall projection 22 a longitudinally extending receiving groove 23 into which an edge portion of the storage plate 8 is inserted. As a result, the storage tray 8 is positively connected to the support bar 19. The simsförmige wall projection 22 may be integrally formed with the support bar 19.
