  • the second bearing unit may be roller-mounted with respect to the first.
  • the operability of this pull-out system suffers as soon as the bars of the first storage unit are contaminated by fermentation processes, because then either the sliding properties of the plain bearing or the ease of rolling elements are impaired. In addition, it turned out that the pullout system jammed quickly when the rods are skewed or not parallel.
  • the object of the invention is to develop a generic pull-out system such that it is largely insensitive to contamination of the guide elements and imperfections in the assembly of the guide elements.

  • the game is in any case dimensioned so that positional deviations of the rails can be compensated within the framework of the assembly tolerances. It is thus possible for the rollers running on the rails to follow the deviations with a corresponding lateral movement.
  • rattling is not to be feared because the support element is at least held laterally when it is loaded by a food support.
  • two cooperating carrier elements are in any case connected by a connection to an extension unit. It prevents rattling by the lateral play, because it holds two opposing support elements at a defined distance.

  • a positionally safe running of the carrier element at least three rollers are required: two rollers arranged above the rail transmit the vertically downward weight load on the rail.
  • the roller arranged below the rail guides the rail in a positionally secure manner between itself and the upper two rollers and supports forces from a tilting moment, which acts on a food support held only in its rear region, on the underside of the rail.
  • the lower roller has to transmit considerable forces from the overturning moment. It is therefore advantageous to arrange the lower roller as far back as possible, that is to say at the rear lower end of the carrier element.
  • an upper rear roller should be arranged in order to ensure the most secure position of the support element on the rail.
  • the upper front roller can be arranged at almost any location. The farther it is from the rear rollers, the more stable the carrier element runs on the rail on the one hand.
  • the closer it moves to the rear rollers the further the support member can be moved in an extended position to the front rail end in the vicinity of the operating opening and projecting it with a projecting portion. The further the support element can be moved up to the operating opening, the more comfortable is the operation of the cooking appliance, because thereby the user's gaze almost the whole
  • a catch pin can also be attached to the underside of the rail instead of a roller located under the front upper roller.

A connection of opposing and cooperating support members already at this time would impede their installation unnecessarily. Thus, since the joining of cooperating support elements is advantageous if they are already arranged in the interior of the cooking appliance, the assembly is because of the cramped space and bad
