Description

BACKGROUND

The present invention relates to a refrigerator unit and/or a freezer unit having one or more storage shelves for the reception of refrigerated goods or frozen goods, with the appliance having one or more extension arrangements which are connected to the storage shelves and by means of which the storage shelves can be pulled out of and pushed into the appliance.

Pull-out storage shelves of refrigerator units and/or freezer units have the substantial advantage with respect to fixedly mounted, non-movable shelves that the refrigerated goods or frozen goods in the rear region of the shelves are comparatively easily accessible even when refrigerated goods and/or frozen goods are located in the front region of the shelves. A clearing away of the front region is thus not absolutely necessary. A disadvantage of previously known storage shelves consists of the fact, however, that the position of the shelves is fixedly set so that the appliances are comparatively inflexible with respect to the adaptability of the inner space to changing needs.

SUMMARY

It is therefore the object of the present invention to further develop a refrigerator unit and/or a freezer unit of the initially named kind such that it enables a more flexible use with respect to previously known appliances.

This object is solved by a refrigerator unit and/or a freezer unit having the features of claim 1. Provision is accordingly made for the extension arrangements to be releasably connected to the storage shelves and/or for the extension arrangements to be releasably connected to the appliance. The advantage can be achieved in this manner that the storage shelves can be installed at different heights in the appliance so that a flexible use of the appliance and an adaptation of the position of the storage shelves to the respectively present needs are possible. Provision can be made in this context for the appliance to have an inner container and for the extension arrangements to be releasably connected to the inner container.

Flexibility with respect to the arrangement of the shelves in the vertical direction is possible in that a plurality of extension arrangements are provided in the vertical direction of the appliance, that is are spaced apart in the vertical direction, and/or in that the extension arrangements can be fixed at a plurality of positions spaced apart in the vertical direction of the appliance. If a plurality of extension arrangements spaced apart in the vertical direction are provided, provision can be made for the storage shelves to be selectively connected to one of these extension arrangements so that the desired vertical adjustment can be made. A vertical adjustability is also produced when the extension arrangements can be fixed in accordance with a preferred embodiment of the invention at a plurality of positions spaced apart in the vertical direction of the appliance.

Provision is made in a preferred embodiment of the invention for the extension arrangements to have a part not moved on the pulling out and pushing in of the shelves and a part movable with the storage shelf and for a locking device to be provided which prevents a displacement of the non-moved part. The extension arrangement can, for example, have an extensible rail which is releasably fastened to the storage shelf and which is displaceable relative to the stationary part of the extension arrangement.

The locking device which prevents the displacement of the non-moved part of the extension arrangement can be made, for example, as a projection which contacts a rib or recess of the inner container in the assembled state of the extension arrangement. In addition to ribs and recesses, any other desired fastening means for the extension arrangement are naturally also conceivable.

It is, for example, possible for the projection to be made as a lug which extends, starting from the extension arrangement, laterally to the adjacent wall of the inner container. It is, for example, conceivable that the lug engages into a recess or pocket or other undercut on the inner container such that the extension arrangement can be adequately loaded and is moreover secured against sliding out or displacement.

It is equally possible for the projection to be made as a lug which has a portion which extends vertically or obliquely downwardly and which engages behind a rib or any other suitable projection arranged at the inner container of the appliance.

In a preferred embodiment of the invention, provision is made for the extension arrangements to be releasably connected to the storage shelves. A plug connection can be provided for this purpose, for example. This plug connection can have a part which is arranged at the storage shelf and which engages into a recess of the extension arrangement. It is, for example, conceivable to clip the extension arrangements to the storage shelves by means of the plug connection. Provision can e.g. be made for the plug connection to have a resilient lug which engages behind the recess in the extension arrangement in the installed state and fixes the storage shelf in this manner.

It is particularly advantageous for the storage shelves to have a raised boundary on one or on a plurality of sides or peripherally, said raised boundary securing the goods on the storage shelves against falling down. The raised boundary can be made, for example, as a peripheral rim or another type of raised portion. It can consist of metal or plastic or comprise one or both of these materials. The raised boundary can be made, for example, in bar shape, as a wire or as a metal sheet. There are no restrictions with respect to the type of raised portion.

In a preferred embodiment of the invention, it is releasably connected to the storage shelves, preferably by means of a plug connection.

Provision can finally be made for the storage shelves to consist of glass or to comprise glass.

A collision can take place between the inner door and the storage shelf in the event that one or more storage shelves are pulled out and the door is closed. To prevent this, provision can be made for a catch for the storage shelf to be arranged preferably at the inner door such that said catch pushes in the storage shelf when the door is closed. The catch can, for example, be made as a skirt which is preferably arranged to the side next to the door storage shelves.

In a further embodiment of the invention, the apparatus, preferably its inner container, has one or more mounts at which or to which the extension arrangements or storage shelves without extension arrangement can lie or be fastened, with the extension arrangements, the storage shelves without extension arrangements and the appliance being made such that the extension arrangements can be replaced with storage shelves without extension arrangements. In this embodiment of the invention, the extension arrangements or rib adapters fastened thereto are made such that the storage shelves with prefitted extensible rails fit (releasably) into appliances or can be replaced as desired with “normal” storage shelves, i.e. storage shelves without an extension arrangement, without anything having to be modified on the appliance, on its inner container or on the mounts or ribs or recesses. This brings along the advantage that an appliance can be retrofitted or converted. There is also the possibility of realizing a combination of normal storage shelves (without extension arrangements) with storage shelves with extension arrangements in one appliance.

The mounts can be made as recesses or as ribs in which or on which the extension arrangements or the storage shelves without extension arrangements lie at least sectionally.

The storage shelves with extensible rails arranged thereon can be made in one piece as a shell made of plastic or as a sheet metal drawn part. These parts manufactured in one part preferably have a shaped rim so that no additional parts are required for the peripheral rim.

DETAILED DESCRIPTION OF THE FIGURES

FIG. 1 shows in a frontal view a part region of a refrigerator unit and/or a freezer unit in accordance with the invention in which a storage shelf 10 made of glass is arranged. The storage shelf 10 has a banister-like boundary 20 at its upper side, said boundary extending upward from said storage shelf and preventing goods from falling down on a movement of the storage shelf 10. The boundary 20 preferably consists of hoops, for example made of stainless steel, which are connected to the storage shelf 10 by means of a plug connection and which can preferably be removed without tools in order to be able to clean both the boundary 20 and the storage shelf 10. Holders 12 are located on the upper side of the storage shelf 10 and the ends of the bars are received in them.

The plug coupling 30, which has a resilient lug 32, is located on the lower side of the storage shelf 10. The resilient lug 32 extends through a cut-out, not visible in FIG. 1, of the L-shaped hoop 40 which is connected to the movable part 50 of the extension arrangement such that the parts 40 and 50 are likewise moved on the pulling out of the storage shelf 10. The horizontal limb of the hoop 40 supports the storage shelf 10.

The extension arrangement furthermore has a stationary part 60 which is arranged on the inner container of the refrigerator and/or freezer unit such that it is not displaceable in the extension direction of the storage shelf 10. The stationary part 60 of the extension arrangement has a part section which serves as a guide and on which the movable part 50 of the extension arrangement runs, as can be seen from FIG. 1. A vertically standing section adjoins on this part section and merges into a horizontally extending section which lies on a rib 100, with the rib 100 extending inwardly from the inner container of the refrigerator and/or freezer unit, as can be seen from FIG. 1. A vertically downwardly projecting web is located on the horizontally extending section of the part 60 and engages behind the rib 100 and in this manner prevents the fixed part of the extension arrangement from being pushable forwardly.

The sectional representation in accordance with the sectional line A-A in FIG. 1 is reproduced in FIG. 2. FIG. 2 again illustrates the arrangement of the holder 12 for the bars binding the boundary 20 and located on the upper side of the storage shelf 10. FIG. 2 furthermore illustrates the horizontally extending section of the stationary part 60 of the extension arrangement which lies on the upper side of the rib 100 and which is partly covered by the storage shell 10, as can be seen from FIG. 1. This section has the vertically downwardly projecting lug 62 which engages behind the rib 100 such that the stationary part 60 cannot be displaced forwardly, that is downwardly in accordance with FIG. 2, but remains at the desired position relative to the inner container of the appliance.

The shape of the stationary part 60 of the extension arrangement again becomes clear from the sectional representation in accordance with the sectional line B-B in FIG. 1 which is shown in FIG. 3. This part is supported at the front rib 100 as well as at a rib 110 arranged at a rear region of the inner container. FIG. 3 furthermore again illustrates the vertically projecting lug 62 which engages behind the forward located rib 100 of the inner container at its rear side.

A partial plan view of the storage shelf 10 with boundaries 20 located thereon can again be seen from the sectional representation in accordance with line C-C in FIG. 1, which results from FIG. 4. The same parts are here also marked with the same reference numerals as in the preceding and following Figures. Reference numeral 120 also marks the rib which is shown in FIG. 1 and which is spaced apart from the rib 100 in the vertical direction.

As can be seen from the Figures of the present patent application, a plurality of ribs are provided which are spaced apart in the vertical direction and on which the extension arrangement can be placed so that a vertical adjustment of the storage shelves or of the glass plates is possible in a simple manner. If, for example, the storage shelf 10 should be moved upwardly with respect to the position shown in FIG. 1, the stationary part 60 of the extension arrangement can be removed from the ribs 100, 110 and the extension arrangement with the storage shelf 10 can be positioned at another desired position, for example on the rib 120.

FIG. 5 shows the rear end region of the extension arrangement fixed in a recess 200 of the inner container. The region 200 extends between the rib 110 and the rib arranged thereabove. As can be seen from FIG. 5, the horizontal limb of the stationary part 60 of the extension arrangement lies on the upper side of the rib 110. The initially vertically extending and then horizontally extending lug 61, which contacts the upper boundary of the recess 200 and in this fashion contributes to the fixing of the stationary part 60 relative to the inner container, extends from the horizontal limb.

FIG. 5 furthermore shows the lug 90 which engages over the mounts for the boundary 20 which are located on the upper side of the shelf 10.

The rib 100, on which the stationary part 60 of the extension arrangement lies, can be seen in a perspective view from obliquely below in FIG. 6. Said extension arrangement has the aforementioned lug 62 which engages behind the rib 100, as can be seen from FIG. 6. FIG. 6 furthermore shows the plug connection whose lug 32 projects through a recess of the vertical hoop 40 of the extension arrangement.

FIG. 7 finally again shows a rear corner region of the storage shelf 10 with boundaries 20 which are arranged thereon and whose holders 12 are fixed by the hoop 90.

The present invention has the advantage that, in a preferred embodiment, the extension arrangements can be clipped onto the glass plates or storage shelves so that they are removable without tools for cleaning. The extension arrangements are then inserted onto ribs or pockets of the inner container with undercuts in a slide-resistant manner. It could be imagined in this context that the inner container has ribs which are present as standard and which could then be used for the vertical adjustment of the glass plates with extensible rails. There is thus the possibility of optionally manufacturing with or without extensible rails without having to change anything on the inner container. There is likewise the possibility of taking out fixedly arranged storage shelves or glass plates and to replace them by extension arrangements so that there is also the possibility of retrofitting. As stated above, provision can furthermore preferably be made for a collision to be prevented, in the event that a storage shell or a glass plate has been pulled out and the door is closed, in that a skirt is attached to the inner door, for example to the side of the door storage shelves, which can act as a catch for the glass plate.
