Description

The present invention relates to a device for adjusting a floor or Abstellers a refrigerator and / or freezer.

From the prior art it is known soils or storage, such. B. door racks of a refrigerator and / or freezer, to be able to arrange at different heights in the device interior or on the door to make the device to the individual needs of the user adaptable.

The present invention has for its object to provide a device for adjusting a floor or Abstellers a refrigerator and / or freezer, by means of which in a simple manner a continuous or largely stepless adjustability of the floor or the store of the cooling and / or Freezer is possible.

This object is achieved by a device having the features of claim 1. Thereafter, it is provided that the device has an extending in the direction of adjustment rack, and a pawl and a gear, wherein the gear engages the rack, and the pawl is arranged so that it is movable to different positions. In this case, the pawl engages in a locking position in such a way in the running in the rack gear or in a connected thereto further gear that its rotation is prevented in at least one direction, and are in a release position, the gear free.

The adjustment thus takes place along the rack, wherein the stepless or largely stepless adjustability is achieved by the rolling of the gear in the rack. For defined adjustment, the device has a pawl which prevents the rolling of the gear in the rack in at least one direction of rotation in the locking position. To adjust the device, the pawl must be released, so that in the sequence, the gear can roll back in the rack.

It is thus conceivable that the arrangement comprises a toothed wheel, which runs on the one hand in the rack and on the other hand can be locked by the pawl. It is also conceivable to carry out the arrangement with a plurality of gears or a gear with a plurality of teeth, wherein a gear in the rack runs and a gear can be locked by the pawl. These two gears can, for example, communicate directly with one another or, for example, sit on a common shaft. The gear, which cooperates with the pawl, may have a different toothing than the gear running in the rack. If the toothed wheel cooperating with the pawl has a finer toothing than the toothed wheel running in the toothed rack, it can be achieved that the steps in which the arrangement is adjustable become relatively small. With arbitrarily fine toothing thus an approximately stepless adjustability is possible.

An advantage of this arrangement is that it is possible by this arrangement, to adjust the device to release the pawl only for one adjustment, whereas in a preferred embodiment for the other Adjustment direction a release of the pawl is not necessary. It is conceivable that the device is arranged both horizontally and vertically or at any other angle. Particularly advantageous is the installation of this device with vertically arranged rack. In this case, it is conceivable that the device can be guided from its locking position only by releasing the pawl when an adjustment of the device is intended down. Furthermore, it would then not be necessary, for example in a possible embodiment, to release the lock for an adjustment of the device upwards. With such an adjustment, the gear would automatically solve by its rotation, the pawl.

In a preferred embodiment of the invention, it is provided that the rail or the rail designed as an adapter hardly applies, so that in the width direction only a very small narrowing of the usable area, that is, the storage surface results. This results in a minimal loss of storage space.

Of the invention, of course, also includes the case that the pawl in the locking position prevents the rotation of the gear in both directions of rotation.

Furthermore, it is conceivable that the device comprises a button which is movable in different positions and in at least one position allows or causes the movement of the pawl from the locking to the release position. This results in the advantage for the user to easily cancel the locking of the device for an adjustment.

By this arrangement, it is possible to perform a part of the device as an assembly, which can then be inserted during assembly in the rack. Furthermore, it thereby becomes e.g. it is possible to store the pawl, the gear and the button and the rocker arm in the tray holder.

In addition, it is advantageously conceivable that the tray holder covers the gear with walls laterally and / or leads. This results on the one hand the advantage that possible risk of injury can be avoided by the rotating gear. On the other hand, for example, jumping out of the gear from the rack is avoided by the leadership of the gear in the tray holder.

A further advantageous embodiment may be to provide a spring which presses the pawl in the locking position. This allows, for example, that the pawl securely remains in the locking position. For a release of the pawl thus additionally the spring force of the spring must be overcome be because the spring force is preferably opposite to the direction in which the pawl is transferred from the locking to the release position.

Furthermore, it is advantageously conceivable that the tray holder forms a dome, in which the spring can be accommodated, and / or this dome has guide surfaces. This results in the advantage that the spring during assembly can be easily arranged and remains safe in operation in position relative to the pawl. This effect can be further promoted by the formation of guide surfaces through the dome. This also results in the advantage that the pawl is guided in the dome so that an optimal introduction of the weight of the parked on the shelf goods on the storage rack is made possible in the rack.

It is particularly advantageous to design the dome with guide surfaces having a surface finish in such a way that the pawl can be moved back and forth in the dome in a low-resistance and / or jerk-free manner. On the one hand, a secure locking and releasing achieved by this, on the other hand, it can be an adjustment pleasant, because less power needed to design. Guide surfaces with such a surface finish can be achieved, for example, in that the dome or the storage holder are formed from a plastic whose surface has good sliding properties. Of course, it is also possible to carry out the storage holder and the other parts of the device from suitable materials such as glass, metal and / or different plastics.

In addition, it is conceivable that the storage holder has a receiving device, in which a storage surface can be preferably detachably mounted.

It is particularly advantageous if the receiving device of the storage holder is listed as a groove. By this embodiment, for example, the storage surface can be positively connected to the storage holder.

Furthermore, it is conceivable that the storage holder has holes for at least one headband. This is particularly advantageous if the device, for example, to be attached to a door of a refrigerator and / or freezer and on the device z. B. bottles should be turned off. By the headband then, for example, a tilting out of the bottles when opening the door can be avoided.

A particularly advantageous embodiment may consist in that two or more storage holders are provided and that a gear of a storage holder is connected to a synchronization shaft with a gear of another, for example, the adjacent storage holder, which carries the same floor or Absteller. This results in the advantage that the two adjacent storage holder can be adjusted synchronously and locked in the same height. Furthermore, it is conceivable to provide a plurality of storage holders for supporting a particularly wide storage area. For their synchronization with respect to their locking position, it may then be necessary to use one or more synchronization shafts and / or gears.

In addition, it may be provided that the synchronization shaft and the gears are positively connected. This results in the advantage of a process-safe design of the gear-shaft connection, as a faulty assembly is excluded by the positive connection. Likewise, this results in the advantage of an exact alignment of the gears connected by the synchronization shaft.

Furthermore, it is conceivable to perform the gears as equal parts. This results in the advantage that cost advantages can be realized in the production or procurement of the gears. Likewise, during assembly a likelihood of confusion can be excluded.

In addition, an advantageous embodiment may be to make the synchronization shaft of a torsionally rigid material and / or to reinforce it torsionally rigid. As a result, for example, the life of the synchronization shaft can be increased.

Furthermore, it is conceivable to carry out the synchronization shaft made of steel. Steel shafts have, in addition to their torsional stiffness, for example, the advantage that they can be easily made from readily available semi-finished products.

Likewise, it may be particularly advantageous to perform the rack as an adapter for mounting in a refrigerator and / or freezer. This may result in the advantage of the adapter already on z. B. in the interior mounted strips. Refrigerators older models could thus be easily retrofitted.

It is furthermore particularly conceivable for the adapter to have at least one receiving device for a bolt. This results in the advantage that the end of the adapter can be positively closed with a latch. It is conceivable to provide each end of the adapter with a latch.

In addition, it may be advantageous for the adapter to have a guide which guides the storage holder in the axial direction of the adapter. This has the advantage that the movement of the tray holder is possible relative to the adapter only in the adjustment direction.

It is particularly advantageous to carry out the bolt as an abutment for adapter mounting and to prevent a bearing change of the adapter thereby. By such an arrangement, it is possible, for example, the adapter simply z. B. mount by attaching to the adapter attachment, and to fix it in the sequence with the bars. Slipping out of the adapter from the adapter attachment, in particular in the axial direction of the adapter mounting is prevented.

An advantageous embodiment may moreover be that the bolt prevents retraction of the tray holder from the rack. This can be z. B. be achieved in an advantageous manner by the fact that the latch touches the end of the rack and there is increased relative to the teeth of the rack.
