Apparatus for adjusting the height of a counter which is guided in a household device by way of at least one pull-out guide

An apparatus for adjusting the height of at least one counter, the at least one counter guided in a household device by at least one pull-out guide, the apparatus comprising:

• at least one sliding rail on which the at least one counter is guidable and configured to be pulled out in a pull-out direction;
• a height adjustment mechanism configured to be fixed to opposing side walls of the household device;
• the height adjustment mechanism including two arms which are rotatably fixed to each of the side walls with first ends of the arms being parallel to a plane of the side walls and arranged to be spaced parallel with respect to each other;
• two guide rails being fixable to respective second ends of the arms in a rotatable manner parallel to the plane of the side walls in such a way that the guide rails are configured to be lifted from a bottom position in the household device to an upper position;
• and
• an energy storage device fixed to at least one of the opposing side walls of the household device, which energy storage device is in operative connection with one of the arms fixed to the at least one opposing side wall in such a way that one of a lifting and lowering of the guide rails is supportable by energy stored in the energy storage device.
