Piece of furniture and device for pushing out a furniture part

Abstract

The invention proposes a piece of furniture and a device for pushing out a furniture part which is accommodated in a movable manner on a fixed furniture part, having a pushing-out lever which can be driven via a drive unit, is fitted on one of the two furniture parts and is temporarily in contact with the other furniture part in order to push out the movable furniture part, and the pushing-out lever has an abutment region within which the contact between the pushing-out lever and the other furniture part takes place, it being possible for the pushing-out lever to be driven, the intention being for the contact between the pushing-out lever and the other furniture part to be eliminated during a pushing-out operation. According to the invention, the abutment region has an inflection, and the pushing-out lever is designed to deform elastically during the pushing-out operation.

1 . A device for pushing out a furniture part which is accommodated in a movable manner on a fixed furniture part, comprising a drive unit, a pushing-out lever driven via the drive unit and being fitted on one of the two furniture parts in temporary contact with the other furniture part in order to push out the movable furniture part, the pushing-out lever having an abutment region within which contact between the pushing-out lever and the other furniture part takes place, wherein the pushing-out lever is driven and then contact between the pushing-out lever and the other furniture part is eliminated during a pushing-out operation, and wherein the abutment region has an inflection. 
   
   
       2 . A device for pushing out a furniture part which is accommodated in a movable manner on a fixed furniture part, comprising a drive unit, a pushing-out lever driven via the drive unit and being fitted on one of the two furniture parts in temporary contact with the other furniture part in order to push out the movable furniture part, the pushing-out lever having an abutment region within which contact between the pushing-out lever and the other furniture part takes place, wherein the pushing-out lever is driven and then contact between the pushing-out lever and the other furniture part is eliminated during a pushing-out operation, wherein the abutment region has an inflection, and wherein the pushing-out lever deforms elastically during the pushing-out operation. 
   
   
       3 . The device as claimed in  claim 1 , wherein a change in position of one end of an elastic part of the pushing-out lever brought about by the elastic deformation during the pushing-out operation is at least 2% in relation to the length of the elastic part of the pushing-out lever. 
   
   
       4 . The device as claimed in  claim 1 , wherein a change in position of one end of an elastic part of the pushing-out lever brought about by the elastic deformation during the pushing-out operation is at least 5% in relation to the length of the elastic part of the pushing-out lever. 
   
   
       5 . The device as claimed in  claim 1 , wherein the pushing-out lever is an angled lever with, in the abutment region, the inflection by way of which two essentially rectilinear sections of the abutment region are oriented at an angle in relation to one another. 
   
   
       6 . The device as claimed in  claim 1 , wherein the pushing-out lever has a part which behaves essentially rigidly during the pushing-out operation and a part which deforms elastically during the pushing-out operation and comprises the abutment region. 
   
   
       7 . The device as claimed in  claim 1 , wherein the abutment region of the pushing-out lever is designed with multiple inflections. 
   
   
       8 . The device as claimed in  claim 1 , wherein the inflection in the abutment region is configured rigidly, in which case there is no change, during the pushing-out operation, in an angle of inflection formed by the relevant inflection. 
   
   
       9 . The device as claimed in  claim 1 , wherein the inflection in the abutment region is designed such that it can be changed elastically under load. 
   
   
       10 . A device for pushing out a furniture part which is accommodated in a movable manner on a fixed furniture part, comprising a drive unit, a pushing-out lever driven via the drive unit and being fitted on one of the two furniture parts in temporary contact with the other furniture part in order to push out the movable furniture part, the pushing-out lever having an abutment region within which contact between the pushing-out lever and the other furniture part takes place, wherein the pushing-out lever is driven and then contact between the pushing-out lever and the other furniture part is eliminated during a pushing-out operation, wherein the abutment region has an inflection, and wherein the pushing-out lever is configured to allow a pushing-out operation in the manner of a toggle mechanism. 
   
   
       11 . The device as claimed in  claim 10 , wherein the pushing-out lever comprises a toggle which is fitted on one of the furniture parts and has limbs which are angled in relation to one another in a head section, the head section coming into direct abutment against the other furniture part during the pushing-out operation. 
   
   
       12 . The device as claimed in  claim 10 , further comprising an overload-prevention mechanism for the toggle mechanism to allow the pushing-out lever to yield counter to a movement which is necessary for the pushing-out operation. 
   
   
       13 . A piece of furniture with a movable furniture part which is accommodated in a movable manner on a fixed furniture part, comprising a device as claimed in  claim 1 . 
   
   
       14 . A piece of furniture with a movable furniture part which is accommodated in a movable manner on a fixed furniture part, comprising a device as claimed in  claim 2 . 
   
   
       15 . A piece of furniture with a movable furniture part which is accommodated in a movable manner on a fixed furniture part, comprising a device as claimed in  claim 10 .
