Description

The invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, comprising a thermally insulated inner container which lines a storage space for refrigerated goods, at least one shelf for storing refrigerated goods, as well as holding means provided on the inner container, which cooperate with counter holding means of the shelf to the shelf in a Kühlgutlagerposition in the Keep inner container, wherein the holding means has at least one upwardly facing support surface and at least one downwardly facing support surface and between support surface and support surface the counter holding means is mounted extendable together with the shelf, the shelf in its Kühlgutlagerposition secured by a locking means against slipping in the direction of withdrawal is.

The 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 closed by a door which has at least one storage compartment with a receiving space for refrigerated goods on its inside facing the refrigerator compartment, wherein the storage compartment is assigned an additional storage compartment, the is provided outside of the receiving space of the storage compartment 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 kept secured in their Kühlgutlagerpositionen against slipping in the pull-out.

This object is achieved by a refrigerator, in particular domestic refrigeration appliance, comprising a thermally insulated inner container lining a storage space for refrigerated goods, at least one shelf for storing refrigerated goods, and provided on the inner container holding means which cooperate with counter holding means of the shelf to the shelf in a Kühlgutlagerposition to hold in the inner container, wherein the holding means has at least one upwardly facing support surface and at least one downwardly facing support surface and between support surface and support surface the counter holding means is mounted extendable together with the shelf, the shelf in its Kühlgutlagerposition by a locking means against slipping in Extraction direction is secured, and the latching means are designed to position the shelf positively and positively secured to secure.

To secure the shelf supported non-positively, the locking means may have a locking projection and / or have a protruding nose, which is frictionally supported on the support surface and / or the support surface or interposed therebetween frictionally. By the latching projection and / or the protruding nose the existing positive positioning is additionally secured by means of a frictional connection.

The at least one shelf can be stored in an operating position of the refrigerator in particular substantially horizontally extendable. The at least one latching means may be designed to keep the shelf in the refrigerated goods storage position secured against slipping out in the pull-out, in particular during transport of the refrigerator.

The at least one latching means can be braced with a spring force which prevents an independent release of the shelf or the counter holding means of the holding means, in particular by gravity on the shelf, a manual extraction of the shelf, in particular in a horizontal direction in an operating position of the refrigerator however, it still allows.

By the holding means with at least one upwardly facing support surface and at least one downwardly facing support surface between which the counter holding means of the shelf is guided, the shelf is not only extendable stored, but also given tilting or falling out in the vertical direction of the refrigerator. Slipping out of at least one shelf, especially when the refrigeration device is tilted forward for transport purposes, is prevented in the pull-out by the locking means according to the invention. The latching means act between inner container and shelf, in particular between the holding means and the counter-holding means and form an initially positive connection, which can be overcome by a resilient design of a detent spring according to the invention by manually moving the shelf with a certain force. The power can be chosen so big, that an accidental slipping out of the shelf, in particular due to gravity is prevented.

The latching means may comprise a projecting from the support surface and / or from the support surface of the holding means in the direction of the counter-holding means nose, wherein the counter-holding means or the shelf may have a detent spring with a latching projection which engages in the Kühlgutlagerposition behind the protruding nose. The nose can thus be arranged in a space, in particular in a limited of support surface and support surface groove. The nose may be a lowering, in particular small depression on the underside of the groove or on the support surface of the holding means. The nose or the depression forms a constriction in the groove, behind which a catch spring according to the invention can engage behind.

Alternatively, the latching means may comprise a recess formed on the support surface and / or on the support surface of the holding means, in which a projecting latching spring of the counter-holding means or the shelf locks in the Kühlgutlagerposition. In this embodiment, therefore, not a projection of the detent spring engages behind the nose or the depression, but a projection of the detent spring penetrates into the recess or a recess on the support surface and / or the support surface of the holding means in order to create a positive connection.

In all embodiments of the invention, the detent spring may be resiliently biased by a separate spring, or be formed via a resilient web portion on the counter-holding means, the shelf or a plastic strip or a plastic frame.

In an alternative or supplementary embodiment, the latching means may comprise a projecting nose and / or indentation formed on an inner side wall of the inner container between the support surface and the support surface of the holding means, to which a detent spring of the counter-holding means or the shelf engages in the refrigerated goods storage position. In this embodiment, the shelf or a glass plate is clamped by the two opposite side edges or gripped like a pincers. So here is not the detent spring opposite support surface and / or support surface necessary, but two opposing projecting noses and / or indentations act by means of the two locking springs against each other.

The locking means may be arranged in a front region of the holding means, in particular on opposite side walls of the inner container and / or on opposite side edges of the shelf. By this arrangement of the locking means, the locking means may also be provided with unlocking means which can be manually operated by a user from the front, for example, to reduce a detent force by manual counterpressure to easily pull out the shelf can.

The holding means can be formed by recesses, in particular grooves, which are arranged on opposite side walls of the inner container, in particular like a tread, repeating in several vertical positions.

Alternatively, the holding means can be formed by projections which are arranged on opposite side walls of the inner container, in particular like a tier, repeating in several vertical positions.

In all embodiments of the invention, the detent spring may be attached to a counter-holding means connected to the shelf or be formed integrally with a counter-holding means attached to the shelf.

In all embodiments of the invention, the shelf may have a glass plate to which the detent spring is directly attached.

In all embodiments of the invention, the shelf may have a glass plate to which a plastic strip is attached, which carries the detent spring and / or on which a plastic frame is molded, which carries the detent spring.

In all embodiments according to the invention, the holding means and / or the counter holding means may be designed to store the shelf with its opposite sides on the inner container in the storage room. Alternatively or additionally, the holding means and / or the counter-holding means may be formed, the shelf in one of the opening plane facing, front or middle depth region support such that the rear wall of the inner container facing rear depth range of at least there cantilevered shelf protrudes in an inserted position in the direction of the rear wall.

In other words, the shelf is supported only in a front or middle area of the holding means and / or the counter-holding means and a rear portion of the shelf is supported by no storage means, but projects freely beyond the support of the front and middle area in the direction of the rear the rear wall of the inner container addition. In the extended state of the shelf then the rear wall of the inner container facing rear depth region of the shelf can be supported by the mounting rails and the front portion of the shelf projecting forward freely beyond the support to the front. Thus, an improved extraction and insertion of the shelf can be achieved using particularly short holding means or counter holding means.

In all embodiments of the invention, the holding means and / or the counter-holding means may be designed to support the shelf in a region between a front edge of the shelf and a maximum depth of two-thirds of the total depth of the shelf. In other words, the shelf projects more than one-third of its total depth to the rear, i. towards the rear wall of the inner container. Instead of a maximum of two thirds of the total depth of the shelf may be supported in a limited embodiment, only over half of its total depth or even less, such as only in a central region by the holding means or the counter holding means.

In summary, and in other words thus results from the invention, inter alia, a catch which secures the one or more shelves against accidental slipping out, especially during transport of the refrigerator. In the front region of, for example, grooves, a small depression can additionally be attached to the underside of the groove, for example. In this undercut subsidence can engage a resilient part of the Glasplattenumspritzung to secure the shelf in the groove. Such locking is sufficient to secure the shelf sufficiently, for example, for transport and so on any costly Additional attachment factory to be able to do without. The devices can also be delivered in a configuration that is later used by customers.

The inner container design according to the invention offers optimum space with high insulation of the inner container. The grooves can be kept as narrow shelves as narrow and short as possible, so as not to weaken the isolation of the side walls as possible. So can be dispensed with editions, which protrude into the inner container and reduce the usable footprint on the shelves.

The associated inner containers are to be produced by the simpler geometric design with simple tools. The tools necessary for a foaming process can be simple. In known container geometries Schäumwerkzeuge with slide are needed. The tools for inner container according to the invention come without elaborate slide in the tool. The tools are thus much cheaper to manufacture and maintain.

The latching invention can be combined with a height adjustment for shelves, in which an adjustment of the shelves is horizontal and possible without tilting. As a result, these shelves must not be completely cleared in an adjustment in each case.

Thus, the inner container can be designed so that shelves can be locked without additional effort. The inner container design stores shelves in a design in short grooves, which are recessed from the sidewall insulation. The length of these grooves may be slightly shorter than the clear width between the beginning of Nutenfeldes and possible obstacles on the inner door. Possible obstacles may be on the inside of the door leaf projecting door racks, which limit the exit path of the shelves in a 90 degrees open door.

So shelves can also be removed horizontally from the Nutenfeld and horizontally inserted into higher or lower grooves locking. Tilting or twisting the shelves is not necessary. Shelves can thus be implemented with refrigerated goods loaded.

Further features and advantages will become apparent from the following description of embodiments with reference to the accompanying figures. Concrete features of these embodiments may represent general features of the invention.
