  • the solution according to the invention makes loading of the storage compartment significantly easier, since the movable support surface can be pivoted out of its opening level. On the other hand, a dead volume that is not accessible for storage purposes is avoided within this storage compartment, so that the useful volume of the storage compartment is increased.
  • the solution according to the invention enables a must-have structure for the support of the adjacent sections of the magnetic seal on the support surfaces provided for this purpose, on the basis of which the locally fixed support surface can be significantly reduced in height, since the resulting tolerance structure can be largely shifted towards the movable support surface.
  • the movable bearing surface serves to support the lower-lying section of the adjacent sections of the magnetic seal.
  • a particularly rigid and dimensionally stable support surface is obtained if, according to a further advantageous embodiment of the object of the invention, it is provided that the movable support surface is designed as a spar-like cross member provided on the lower one of the stacking compartments arranged one above the other and can be pivoted about a horizontal axis of rotation.
  • a further advantage of this solution is the pivoting path defined by the axis of rotation and the easily moving movement mechanism resulting from the rotary movement.
  • the horizontal axis of rotation of the spar-like cross member is arranged closer to the door over the center of gravity of its cross section and off-center to its width.
  • the spar-like cross member after it has been deflected from its support position, automatically pivots into an instantaneous intermediate position without the use of additional return means, such as springs or the like, only under the influence of gravity acting on it, from which the final support position on the cross member for the corresponding section of the magnetic seal, for example when inserting the pulled-out top storage compartment of the lower storage compartment, is reached automatically.
  • additional return means such as springs or the like
  • a spar-like crossmember has a particularly simple and thus easy-to-assemble structure if, according to a further advantageous embodiment of the subject of the invention, it is provided that two mutually opposite stub-like approaches, which are rotatably mounted in the housing of the refrigerator in bearing mounts, serve as the horizontal axis of rotation for the spar-like crossmember. which form the storage means.

  • a particularly positionally secure and stable holding device for the spar-like cross member results if, according to a next advantageous embodiment of the object of the invention, it is provided that the holding means as mutually interlocking and interacting, on the one hand on spar-like cross member and on the other hand arranged latch hooks are formed.
  • the spar-like cross member can be brought from its support position into its pivoting position by a control link arranged on the storage compartment closest to it in the lower storage compartment.
  • Such a solution is characterized by the fact that an operator can effect a pivoting of the cross member in a particularly simple manner, without additional handles, simply by pulling out the storage compartment and can thus pull the storage compartment out of the storage compartment up to its pull-out stop.
  • a particularly precise coordination between the extension path of the storage compartment and the pivoting movement of the spar-like cross member with a simultaneous reduction in force during the movement of the storage compartment results if, according to a next advantageous embodiment of the object of the invention, it is provided that the control link on the storage compartment with a cam contour on the spar-like Cross member interacts with the lower storage compartment when pulling out the storage compartment.
