Definitions

  • the present invention relates to a pull-out guide, in particular for ovens, with at least two guide rails, which can be moved relative to one another via rolling elements, wherein at least one guide rail has a body of a sheet steel.
  • EP 994 309 discloses a telescopic extension device for a food support having at least partially withdrawable rails, wherein the rails and the guides have at their sliding surfaces a temperature-resistant sliding material made of a metal nitride.
  • the rails can be made entirely from this sliding material, so that they can be used both for the maximum operating temperatures and for a Pyrolysepository in which temperatures can occur at 500 0 C.

  • At least one guide rail has a body made of a steel sheet which is coated with aluminum.
  • the aluminum coating gives the guide rail high temperature and corrosion resistance.
  • the guide rail can also be used at temperatures of up to 500 0 C, which occur during pyrolysis. In this case, the problem of scaling of the stainless steel surfaces is avoided because the layer of aluminum does not have such disadvantages.
  • all guide rails on an aluminum coated body made of sheet steel are used particularly well in ovens, since such guide rails can be classified as safe from a food law perspective.
  • the layer of aluminum is applied by electroplating.
  • a particularly uniform layer thickness can be achieved, for example in a range between 4 ⁇ m to 15 ⁇ m, in particular 6 ⁇ m to 12 ⁇ m.
  • Galvanizing does not adversely affect the structure of the main body due to the high temperature of a melt in its characteristics.
  • the layer of aluminum has a heat resistance of more than 500 0 C, preferably more than 600 0 C in a further embodiment.
  • the rolling elements are held in a cage, which is also coated with a layer of aluminum.
  • the pull-out guide can be composed of known components, which are refined only by coating with aluminum. This simplifies the manufacturing process considerably.
  • the aluminum layer is applied by electroplating after the molding process in order to achieve a sealing of the cut edges.
  • Passivation of the applied aluminum layer has a positive effect on its resistance to aggressive media and on its corrosion resistance.
  • balls or other bodies made of ceramic can be used, but other materials can be used.
  • Figure 1 is an exploded view of a pull-out guide according to the invention.
  • a pull-out guide 1 comprises a running rail 2, which is movably held on a middle rail 4, which is held on a rail 5, which can be mounted, for example, on an inner wall of a baking oven.
  • a stopper 3 is provided so that a food support can be placed on the running rail 2.

  • the stopper 3 may also be formed of a steel sheet with an aluminum coating.
  • the pull-out thus prepared has a temperature resistance of more than 500 0 C, preferably more than 600 0 C. This is an insert in ovens possible in which the pyrolysis process is used for self-cleaning.
