The EP 2 159 523 A1 describes a kitchen refrigerator having a console system adapted to couple a refrigerated goods drawer to side grooves of an inner container of the kitchen refrigerator. The console system has two opposite side parts. Each side part has a fixing part to fix the side part in the groove and it has a slide rail to extend the refrigerated goods drawer extendable on the side part. To form a side part, the fastening part and the slide rail are connected by separate fastening means, such as screws. The EP2159523A1 discloses a refrigerator according to the preamble of claim 1.

The DE 20 2004 017 136 U1 describes a telescopic rail system, in particular for refrigerators and / or freezers, with a support plate for mounting the telescopic rail system in the inner container of the refrigerator and / or freezer and two opposite to the support plate in the side regions arranged telescopic rails. The telescopic rails can be arranged on a surface of the support plate.

The object of the invention is to provide a holder for shelves in refrigerators, by which one or more shelves are mounted extendable in a simple manner. This object is achieved by a refrigerator, in particular domestic refrigeration appliance, comprising a thermally insulated inner container which forms a storage space for refrigerated goods, at least one shelf for storing refrigerated goods, as well as at least two opposing arranged on the inner container retaining grooves for the shelf, and having a mounting rail with a mounting portion seated for insertion into the retaining groove for supporting the mounting rail on the inner container, and having a guide portion adapted to slidably guide the shelf for telescopically supporting the shelf in the storage space, the support rail acting as a rigid single component is formed, which has an angle profile, in which a first angle leg of the support rail forms the guide portion and a second angle leg forms the mounting portion, the support rail to form a transition or interference fit between mounting section un d holding a fastening portion, whose contour is adapted to the internal dimensions of the retaining.

The mounting rails are designed as rigid individual components. The support rails may be configured to be inserted by a user into retaining grooves provided on inner sidewalls of the inner container. In particular, the support rails may be designed to be used in retaining grooves, which are designed for immediate retention of edges of a shelf.

By means of the mounting rails according to the invention, it is also possible, for example, to retrofit refrigeration appliances which in themselves were designed only to receive shelves directly at their side edges in the inner container, ie. to keep. Thus, by means of the support rails according to the invention one or more shelves extendable be performed in the inner container and / or other shelves are stored directly in the holding without using the support rails.

The support rail has to form a transition or interference fit between the mounting portion and retaining a mounting portion whose contour is adapted to the internal dimensions of the retaining. Thus, a user can reliably manually fasten the mounting rails to inner sides of the inner container without the use of tools. The mounting rail can be designed to be releasably attachable to the retaining grooves, so that a user if necessary, the support rails remove the refrigerator and in particular without the need for tools.

In all embodiments of the invention, the support rail may have a holding means to hold the support rail in the retaining groove positively and / or frictionally. In a special embodiment, the mounting rail may have a latching means which is designed to hold the mounting rail in a form-fitting manner in the retaining groove. The locking means may serve to keep the mounting rail secured in the respective retaining groove. The locking means may be formed, manually operated, or to be solved.

The retaining groove may have a recess into which a projection of the locking means engages positively in a position of the fastening portion attached to the retaining groove. Through a combination of return and projection a positive connection is created. Due to the positive connection, the mounting rail according to the invention is particularly reliable secured to the inner container or the inner wall against unintentional loosening.

In all embodiments of the invention, the support rail may have a stop which is designed to limit a maximum extension length of the shelf. By limiting the maximum extension length of the shelf falling out and / or tilting of the shelf from the refrigerator is prevented. Thus, refrigerated goods stored on the shelf remain reliable and the risk of falling down is reduced.

The stop can be formed by a projection on a lower wall of the support rail, to which an edge portion of the shelf is present at maximum extension length of the shelf. Depending on the depth of the shelf, the edge portion of the shelf can be arranged such that only a predetermined uncritical part, for example, at most half the depth of the shelf can be pulled out of the refrigerator protruding.

In all embodiments according to the invention, the mounting rail has an angle profile. The angle profile may in particular be a rectangular cross-section L-shaped profile. In all embodiments of the invention, the support rail in this case has a first angle leg, which forms the guide portion, and a second angle leg, which forms the attachment portion. The guide section of the first angle leg can in particular be designed as a web.

In all embodiments according to the invention, the guide section may have a web which projects in the horizontal direction and at least approximately parallel to a side wall of the inner container and predetermines an extension direction. The web forms a guide, which can specify the extension direction and the extension angle.

By the shelf by a guide portion on the support bar on the roller, which can be rotatably supported by means of Rolling friction is performed, a pulling and pushing the shelf with reduced effort. ie easier for a user.

The guideway may be arranged in a hollow profile of the shelf. By the guideway is arranged in a hollow profile of the shelf, both the guideway and optionally also the role of dirt can be protected. Alternatively or additionally, the shelf can be pulled out and inserted safe to use, since the arranged in a hollow profile of the tray guideway protection is created, which shields the role against contact.

The shelf may have a glass plate to which the bar, in particular plastic strip is attached directly. The strip can be arranged circumferentially on an outer contour of the shelf. In particular, the plastic strip may be molded onto the outer edges of the glass plate, added, in particular clamped or glued.

The strip, in particular plastic strip, can be connected to a refrigerated goods retaining wall extending upwards in the manner of a frame around the shelf, in particular the glass plate, extending upwards from the plane of the shelf, in particular from the plane of the glass plate.

In summary, and in other words, the invention thus provides, inter alia, a refrigeration device which can be equipped with extendible planes, i. Shelves is equipped. By means of the mounting rails according to the invention can be dispensed with expensive, prefabricated extension systems. Especially in price segments that do not allow the use of full-extension systems, the mounting rails according to the invention can be used cost-optimized.

An inventive pull-out system for shelves, in particular tray-shaped shelves can consist of an overmolded glass shelf, 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 this support strips, the Auszugsweg can be limited by locking lugs or stops. The support bars and the shelf may thus form an assembly that can be easily inserted, for example, in a sidewall rib field, i. a plurality of superimposed retaining grooves, in particular on opposite side walls of the inner container, implemented and can be varied in the altitude.

The strips rest in groove-like receptacles in the refrigerated goods container.

The support strips can be fixed in the inner container via a molded detent spring. The strips could be designed as low-priced injection-molded parts. The shelf may be an overmolded glass plate. Although the two rails mean additional expenditure on additional costs of this extendable system in comparison to a fixed attachment of the shelves. This solution is particularly suitable for less expensive devices and series.

The extraction path, which is made possible by this simple system, is completely sufficient to considerably facilitate access to stored refrigerated goods. An optionally raised edge of these pull-outs can clearly separate the chilled goods from the inner wall. Such a separation prevents refrigerated goods touched the container walls and is offset by the extension movement and could fall over.

Further advantages will become apparent from the following description of an embodiment with reference to the accompanying figures.
