  • the solution according to the invention creates a fastening possibility, which is also suitable for mass production in the consumer goods industry, for reinforcement bodies which are referred to as backing parts and which is characterized by a high positional accuracy, due to the technical drawing of the cup-like molding on the inner lining. Due to the cup-like, serving as a positioning aid for the reinforcing body, a breakthrough on the inner lining for finding the position of the reinforcing body is unnecessary, so that penetration of the thermal insulation material introduced into liquid starting components into the cooling or freezing space delimited by the inner lining at the mounting location of the reinforcing body is safely avoided. In addition, quality drops in such a solution for fastening the reinforcing body are largely excluded due to the principle.

  • the reinforcing body placed on the molded part is held particularly securely against rotation, if after another advantageous one Further development of the object of the invention is provided that the fastening section is provided with means which are able to cooperate in a form-fitting manner with the heat insulation material and secure the reinforcing body against rotation. Furthermore, the positive and / or non-positive connection of the reinforcing body is relieved with the molding.
  • the means on the fastening section are designed as ribs which protrude radially on its lateral surface and extend in the direction of its longitudinal axis.
  • the fastening section By designing the fastening section in this way, undercuts for receiving the thermal insulation material introduced into liquid starting components and subsequently curing are created, so that the reinforcing body, in addition to its non-positive and / or form-fitting attachment to the cup-like molding, is also provided by the heat-insulating material both in the direction of insertion of the screw-like material Fastening means as well as is supported in a form-fitting manner.
  • a particularly intensive support and clawing of the fastening section in the heat insulation material in the direction of insertion of the fastening means and in the opposite direction results if, according to a next advantageous embodiment of the object of the invention, it is provided that the ribs are provided over the entire length of the fastening section and are at least approximately the same height as the Complete the lateral surface of the receiving section.
  • a particularly expedient and uniform application of force to the heat insulation material in the direction of insertion of the fastening means and in the opposite direction is obtained if, according to a further advantageous embodiment of the object of the invention, it is provided that four ribs are arranged on the lateral surface of the fastening section, which are approximately in equidistantly distributed over the circumference of the fastening section.
  • the cup-like molding and the reinforcing body are particularly easy to produce if, according to a last preferred embodiment of the subject of the invention, it is provided that the cup-like molding and the reinforcing body are provided with a circular cross section. At the same time, this design results in a particularly assembly-friendly solution.
  • FIG. 1 shows a detail of a heat-insulating housing for a refrigerator or freezer in a horizontal section, with an inner lining, on which a reinforcing body, which is fixed to a cup-like shape of the inner lining facing the thermal insulation, is arranged on an enlarged scale,
