Definitions

  • the present invention relates to a refrigeration device with a refrigeration compartment, which has an inner container receiving the refrigerated goods with holders formed in the inner container wall for a refrigerated goods carrier.
  • Such a refrigerator is described for example in DE 43 35 160 A1.
  • horizontal guide rails are provided as holders for storage shelves on opposite side walls of the inner container.
  • the guide rails can be formed in the side walls or molded outwards (column 2, lines 14 to 21).

  • Fig. 1 a the slide e are shown in the extended state.
  • the molding of the inner container takes place by first a plastic plate c between the die a and punch b is positioned.
  • the stamp b then moves into the die a, wherein the slide e in the retracted state, ie in the recesses f sunk state.
  • the plastic sheet c made malleable by heating is drawn into the die a by the punch b. If the punch b is completely retracted into the die a, as shown in the sectional views of FIGS. 1 b and 1 c, the slides e are extended from the side of the die a in the direction of the punch b.
  • the slides e pull parts of the already drawn plastic board c in the recesses d, whereby lateral guide rails g are formed.
  • the object of the present invention is therefore to provide a refrigeration device of the aforementioned type, which is simple and inexpensive to manufacture in relation to the holders to be molded into the inner container wall for a refrigerated goods carrier.
