BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding-pivoting mechanism for a furniture component or a household appliance shelf, a sliding-pivoting mechanism, a piece of furniture,

The present invention relates to a sliding-pivoting mechanism of a furniture part or appliance shelf for pulling up and lifting a shelf from a furniture part or a body of a household appliance according to the preamble of claim 1.

The present invention further relates to furniture components and household appliances having such a sliding-pivoting mechanism.

A general sliding-pivoting mechanism is known from DE 10 2012 107 993 A1.

In the case of the sliding-pivoting mechanism disclosed in this specification, the lifting or lowering of the shelf is supported by a tension spring operating on one of the pivot arms.

Thus, loading or unloading of the shelf is possible in the upright position of the user, which relaxes the dorsal muscle and spine.

This sliding-pivoted mechanism is in fact proven its worth.

However, the raising or lowering of the shelves is particularly disturbing when relatively heavy items, especially when the total mass exceeds 10 kg.

In this case, it is not preferable to use a tension spring having a high elastic modulus because the lowering of the shelf in a no-load state is greatly disturbed by such tension springs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sliding-pivoting mechanism of a shelf of a household appliance or household appliance which allows easy lifting or lowering of the shelf.

This object is achieved by a furniture part having the technical features of claim 1 or a sliding part-pivoting mechanism of a shelf of a household appliance for pulling up and lifting the shelf from the body of the appliance.

This object is further realized by a household appliance having the technical features of claim 13 and a household appliance having the technical features of claim 14.

Each of the guide rails of the sliding mechanism is movable in a direction parallel to the plane of the sidewalls in such a manner that the guide rails can be pivoted from the lowered position in the body to the raised upper position at least partially outside the body, And is pivotally secured to each second end.

The sliding-pivoting mechanism further includes at least one running rail, which is linearly positionable within the guide rail and to which the shelf is fixed.

The sliding-pivoted mechanism further includes a lever unit for supporting the lifting and lowering of the pivoting mechanism.

The simple lifting and lowering of the shelf is made possible by a lever unit which supports the lifting or lowering of the pivoting mechanism in a simple manner without changing the elasticity of the tension spring.

Advantageous embodiments of the invention are technical features of the dependent claims.

According to an advantageous embodiment of the invention, the lever unit comprises two lever elements connected to each other by at least one cross member.

The cross member is used as an operation handle.

The lever element may be formed in an angular manner.

The lever element is formed in such a way that the lifting and lowering of the shelf is made possible with less effort compared to the conventional handle being fixed to the shelf or to the shelf itself.

According to a further advantageous embodiment of the invention, the lever element comprises a first leg and a second leg, the first cross member being disposed between the free ends of the short legs.

The second leg is preferably formed in such a manner that the first cross member is located at least in the lowered position or the upper position of the shelf in the raised position or intermediate position.

The first cross member is advantageously located above the shelf at all positions.

Thus, access to the cross member by the user is facilitated in that the cross member is positioned in a higher vertical direction than the shelf itself, especially at the lowered position of the shelf.

The lever element is pivotally secured to the running rail in parallel with the plane of the side wall according to a preferred embodiment.

The first leg preferably includes a roller or sliding element at the free end, whereby the lever element can be supported on the base.

Thus, pivoting of the furniture body in the upward direction through the lever element can be further supported after pulling the shelf to the pivot start position by pulling the first cross member.

According to another embodiment, the lever element of the lever unit is fixed to the pivoting mechanism in such a way that it is disposed parallel to the plane of the side wall.

The lever element is preferably formed in a U-shaped manner and is connected to one of the pivot arms for pivotal movement, in this case by pulling the first cross member to pivot the shelf from the lowered position to the raised position Many advantageous lever effects are utilized.

The lever element of the lever unit may advantageously be formed in a manner that is longer than at least one pivot arm of the pivoting mechanism to achieve a lever ratio that is highly advantageous in pivoting motion.

The lever elements may be formed integrally or in a multi-part manner, and may be rigidly connected to each other.

According to yet another embodiment, the lever unit comprises two lever elements pivotally secured to the pivoting mechanism, the end spaced from the pivoting mechanism being formed in such a way as to be insertable in the pulling direction, Is pivotally connected to a respective lifting element that can be extended or retracted into the unit.

The support of the upward and downward movement of the pivoting mechanism is additionally enabled by such a lifting element that can be driven by a drive unit.

According to an advantageous embodiment, in this case the roller element is arranged at the end of the lever element spaced from the pivoting mechanism through which the lever element is elevated with a relatively small driving force amplified by the lever effect of the lever element And a support in a downward motion.

The furniture parts according to the present invention and the household appliances according to the present invention are characterized by the above-described sliding-pivoting mechanism.

For example, in the case of home appliances formed by dishwashers, the loading and unloading of the lower shelf in the lower area of the furniture body and optionally in the lowered position located below the upper shelf, - pivoting mechanism, which is advantageous not only because the shelf can be moved to a convenient raised position, but also because of the less effort of the shelf to move to the raised position itself.
