The DE 19 751 308 A1 discloses a refrigerator according to the preamble of claim 1.

The EP 1 906 121 A2 describes a refrigerator having walls defining a refrigerator compartment. The refrigerator described comprises at least one shelf for storing food. Two opposite walls have shots for the shelf. Each shelf has a bearing surface and a frame structure surrounding the bearing wire structure.

The object of the invention is to provide a holder for shelves in refrigerators, through which one or more shelves can be easily adjusted by a user in its height position.

This object is achieved by a refrigeration device, in particular domestic refrigeration appliance, comprising a thermally insulated, a storage space for refrigerated inner container forming a pivotally opening and closing of the storage space with respect to an opening plane door leaf, and provided on the side walls of the inner container holding means with at least one counter holding means The support means cooperate at least one upwardly facing support surface and the counter holding means at least one downwardly facing support surface, wherein the at least one support surface on the inner container and the at least one support surface on the shelf designed and / or arranged such that in an inserted position of the shelf, in which the door leaf is closed, which overlap at least one support surface and the at least one support surface and in a partially out of the inner container pulled position of the shelf, the at least one support surface and the at least one support surface are arranged on a gap and wherein the holding means is formed by projections or grooves, which are arranged on opposite side walls of the inner container, in particular floor-like repeated at several altitudes, the counter holding means of projections is formed, which are arranged on opposite side edges of the shelf, and the shelf at opposite side edges each having a, the projection-forming bar extending, in particular at least over half the front depth of the shelf and the corresponding projections or grooves on the inner container itself from a rear depth of the inner container so far forward that they end before reaching the opening plane in a depth which is greater than the length of the strips.

By arranged in a partially pulled out of the inner container position of the shelf, the at least one support surface and the at least one support surface are arranged on a gap, the shelf can be offset in a horizontal orientation in height, without having to remove the shelf completely out of the refrigerator. Thus, for example, the shelf can be offset in a horizontal orientation in height, even if a door leaf of the refrigerator prevents complete removal of the shelf, for example, a swung by 90 degrees door leaf, in which, for example, a door rack partially blocks the opening of the inner container of the refrigerator , In addition, the shelf in a horizontal orientation are offset in height, for example, even if refrigerated goods is still on the shelf.

In the retracted position of the shelf, in which the door leaf is closed, and overlap the at least one support surface and the at least one support surface, the shelf is securely held in the inner container of the refrigerator.

The holding means can be formed in a first embodiment of recesses, in particular grooves, which are arranged on opposite side walls of the inner container, in particular like a floor, repeated in several vertical positions. The recesses or the grooves can be tightened in the side walls of the inner container, in particular be produced by a deep-drawing process.

The counter-holding means can be formed by projections which are arranged on opposite side edges of the shelf. The shelf has at opposite side edges in each case one, the projection-forming bar, which extends, in particular at least over half the front depth of the shelf and the corresponding grooves extend to the inner container of a rear depth of the inner container so far forward that which ends before reaching the opening plane at a depth which is greater than the length of the strips.

The holding means can be formed in a second embodiment of projections, which are arranged on opposite side walls of the inner container, in particular like a floor, repeated in several vertical positions. The projections may be attracted to the sidewalls of the inner container, in particular by a deep-drawing method. In this embodiment, the projections on the original thickness of the side walls of the inner container, so that the example provided by back-foaming with heat-insulating material side walls of the inner container are not weakened in their insulating ability.

The protrusions on the opposite side walls may be combined with protrusions on opposite side edges of the shelf. The projections on the opposite side walls may be provided with projections on opposite sides Side edges of the shelf in particular be combined so that in an inserted position of the shelf in which the door leaf is closed, overlaps at least one projection of the side walls with at least one projection of the shelf and in a partially pulled out of the inner container position of the shelf at least one projection the side walls with the at least one projection of the shelf is arranged on a gap. Instead of a single projection pair on the two opposite sides of the shelf, two, three or more pairs of projections tooth-like or comb-like can be arranged either overlapping or gap.

The counter-holding means can in this case be formed by projections which are arranged on opposite side edges of the shelf. The shelf has at opposite side edges in each case one, the projection-forming bar which extends, in particular at least over half the front depth of the shelf and the corresponding projections extend to the inner container of a rear depth of the inner container so far forward that which ends before reaching the opening plane at a depth which is greater than the length of the strips. In other words, the strip can be arranged in a front depth region facing the opening plane, and the corresponding projections can be arranged on a rear depth region facing the rear wall of the inner container.

Each corresponding projection of the inner container may have a continuous support surface in the depth direction. Alternatively, each corresponding projection of the inner container may have a plurality of spaced-apart, in particular evenly spaced, bearing surfaces in the depth direction.

In all embodiments according to the invention, the counter-holding means and / or the at least one support surface of the shelf can be provided on a plastic strip or a plastic frame, in particular integrally formed with the plastic strip or the plastic frame, which is encapsulated by a glass plate as a shelf.

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 designed to support the shelf in a front or middle depth region facing the opening plane in such a way that a rear depth area of a rear shelf facing the rear wall of the inner container is formed in a retracted position in at least one freely formed shelf Cantilevered towards the back 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, the invention thus provides, inter alia, a height adjustment for shelves in which an adjustment of the shelves is horizontal and without tilting possible. As a result, they have to Shelves in an adjustment not completely cleared away in any case. The invention is without additional parts and resulting additional costs.

Furthermore, the inner container can be designed so that shelves can be locked without additional effort. In known refrigerators shelves, especially glass shelves can be removed only by tilting from the inner container. The inner container design according to the invention supports shelves in a design in short grooves, which are recessed from the side wall insulation. The length of these grooves is 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.

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

In the front region of the grooves may be attached to the underside of the groove additionally a small depression. 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 to dispense with any costly additional attachment factory. 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 inner container according to the invention are to be produced by the simpler geometric design with simple tools. The necessary for a foaming process

Tools, 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.

Further 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.
