They are used in various household appliances but also in the automotive industry and in many other applications.
  • telescopic rails While a variety of applications can already be addressed with the known telescopic rails, telescopic rails have not been able to establish in microwave ovens so far. If a telescopic rail is produced whose rail elements are made of an electrically conductive material, in particular of a metal sheet, the microwave radiation impinging on the telescopic rail during operation of the microwave oven leads to a local charging of the rail elements and to a sufficiently large potential difference between the individual rail elements a spark discharge between them.
  • the invention proposes to design a telescopic rail of the type mentioned above for a microwave oven in such a way that the first rail element has a shielding element moving with the first rail element from a material which is intransparent for microwave radiation of the microwave oven, the shielding element having a connecting section which is substantially parallel extends to the back portion, has a first leg portion and a second leg portion, so that the shielding member surrounds the first and the second rail member having a substantially U-shaped cross section, wherein the connecting portion, the first leg portion and the second leg portion has a length in the extension direction so that the shielding member in the retracting position covers the first and second rail members over their entire length in the extension direction, and wherein the shielding member exposes the connecting rod has cut and the first leg portion connecting, curved first transition section.

  • Microwave ovens can usually only be put into operation when the door of the microwave oven is closed. Only then can the electromagnetic microwave radiation act on the telescopic rail. However, closing the door presupposes that the rail elements of the telescopic rail no longer protrude beyond the muffle of the microwave oven. Therefore, the shielding element is arranged on the first rail element in such a way that it is moved along with it during a pull-out movement of the first rail element.
  • the shielding element is a part made separately from the first rail element, which is then connected to the first rail element. In this case, the connection between the shielding element and the first rail element can be released be designed.

  • the surfaces of the first leg portion and the second leg portion facing away from the first rail member have planar extended surfaces to provide good reflection of the microwave radiation.
  • the shielding element has a material which is intransparent for the microwave radiation of the microwave oven. Such opaque materials absorb or preferentially reflect the microwave radiation.

  • At least the surfaces of the shielding element pointing away from the first and second rail elements are provided with a coating, for example an easy-to-clean coating, a coating with SiO 2 or a ceramic.
  • the shielding element is made of a solid sheet metal without perforations in the material or with only a small number of openings.
  • the pull-in position is understood to mean the position of the first and the second rail element relative to one another, in which the telescopic rail is completely inserted.
  • the retraction position is characterized by the achievement of an end stop.
  • the shielding element covers the first rail element and the second rail element in the pull-in position over their entire length in the extension direction.

  • the rolling elements are balls.
  • the rolling element cage is a ball cage.
  • the rolling elements may be made of an electrically conductive material, for example of steel.
  • the first rail element and / or the second rail element and / or the shielding element are made of a material which is selected from a group consisting of sheet steel, aluminized steel sheet and stainless steel.

  • At least the first rail element or the second rail element has two legs, which form the running surfaces for the rolling elements, and a back section connecting the two legs.
  • the design of a first transition section which connects the connecting section and the first leg section of the shielding element, is of crucial importance. In the region of this transition section, increased heating and electrical charging of the shielding element occurs. Only the inventive design of the transition section with a curved in cross-section perpendicular to the extension direction shape causes a reflection of the microwave radiation in this transition section.

  • the shielding element has a curved third transition section connecting the connecting section and the cover section, this third transition section having a radius of curvature of less than 6 mm, preferably less than 5 mm and more preferably less than 4 mm. It has been found that a small radius of curvature of the third transition section has a greater effect than a reduced reflection on the fourth transition section with a large radius of curvature by associated closing of any gaps through which the microwave radiation can enter the region of the rail elements this place.

Therefore, it is important to design the Gargutyanschlag reflective as possible for the microwave radiation. This is achieved by a curved outer contour with a preferably large radius of curvature. Therefore, the Gargutyanschlag in one embodiment of the invention has a curved outer contour, wherein preferably the radius of curvature of the outer contour is 4 mm or more, preferably 5 mm or more and more preferably 6 mm or more.
  • the product support stopper has a depth in a direction perpendicular to the extension direction, which is at least equal to 2/3 of the depth of the first leg portion in the direction perpendicular to the extension direction.

  • Such an embodiment causes an equipotential bonding of at least one rail element which is exposed to the microwave radiation. It is initially irrelevant whether the resulting local charges drain on an immediately adjacent rail element or another rail element. In the case of a full extension with three rail elements, the charges can alternatively flow onto the middle rail element or onto the inner rail element. It has been found that such contact elements in the retraction position can not only effectively prevent sparking between edges and tips of adjacent rail elements, but also a punctual flow of current through the rolling elements of the telescopic rail.
