Description

Refrigerating appliance with a mounting rail for a shelf

The invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, comprising a heat-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 retaining grooves arranged on the inner container for the shelf.

DE 199 61 786 A1 describes a cooling device with a heat-insulating housing, within which at least one cooling chamber is arranged, which is closable by a door, which has at least one storage compartment with a receiving space for goods to be cooled on its inside facing the refrigerator, wherein the storage compartment additional storage compartment is assigned to the outside of the receiving space of the

Storage compartment is provided and holding means for releasably holding in at least one receptacle on the storage compartment.

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 heat-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 aufeisend a mounting rail with a mounting portion adapted to be inserted into the retaining groove for supporting the support 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 mounting rails can be designed as a 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, for example, refrigerators can be retrofitted, which were only designed to receive shelves directly at their side edges in the inner container, ie to hold. Thus, by means of the mounting rails according to the invention one or more shelves extendable in

Inner container are performed and / or other shelves without using the mounting rails are stored directly in the retaining.

The support rail may have a mounting portion, the contour of which is adapted to the inner dimensions of the retaining groove to form a transitional or interference fit between the mounting portion and retaining. So a user can do the

Mounting rails on inner sides of the inner container without the use of

Tools are reliably attached manually. The mounting rail can be designed to be detachably fastened to the retaining grooves, so that a user can remove the mounting rails from the refrigeration device as needed, in particular without requiring 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. By a combination of return and projection becomes one

created positive connection. Due to the positive connection, the mounting rail according to the invention is particularly reliable on the inner container or

the inner wall secured 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. So remains stored on the shelf refrigerated goods reliably and the risk of falling down is reduced.

The stop can be formed by a projection on a lower wall of the support rail, at which an edge portion of the shelf at maximum

Extent length of the shelf is pending. 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 versions, the support rail may have an angle profile. The Wnkelprofil may in particular be a rectangular in cross-section L-shaped profile. In all embodiments, the mounting rail may have a first angle leg, which forms the guide portion, and have a second Wnkelschenkel, which forms the attachment portion. The guide portion of the first Wnkelschenkels may be formed in particular as a ridge.

In all embodiments according to the invention, the guide portion may be in a horizontal direction and at least approximately parallel to a side wall of the

Inner container ersteckenden, an extension direction predetermining web. The web forms a guide, which can specify the extension direction and the extension angle.

In all embodiments of the invention, the shelf can a the

Guide section, in particular the web encompassing, in particular from above embracing bar, in particular plastic strip. By a comprehensive storage of the shelf to, for example, one or two mounting rails a play-free retractable storage for the shelf can be created.

In all embodiments according to the invention, the support bar, in particular the guide section, may have a roller, in particular a rotatably mounted roller, which rolls along a guide track of the shelf. 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 withdrawal and insertion of 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 on 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 with a frame-like around the shelf, in particular the glass plate encircling, extending from the plane of the shelf, in particular from the plane of the glass plate upwards

Be connected Kühlgutrückhaltewand.

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 rails, the Auszugsweg can over

Be limited locking lugs or attacks. 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 holding grooves arranged one above the other, in particular

opposite side walls of the inner container, implemented and can be varied in 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.
