- 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,
- FIG. 2 shows the reinforcing body in a sectional view from the side in an enlarged view compared to FIG. 1,
- Fig. 3 shows the reinforcing body of FIG. 2 in plan view
- Fig. 4 shows the reinforcement body of FIG. 2 cut along the section line IV-IV.
- 1 shows a detail of a housing wall 10 of a refrigerator or freezer belonging to a heat-insulating housing (not shown), which has an outer cladding 11, a thermal insulation layer 12 produced by foaming and a non-cutting shape lining the interior of the refrigerator or freezer Has inner panel 13 produced plastic board.
- a cup-shaped projection 14 which is circular in cross section and produced during its non-cutting shaping, which extends into the heat insulation material 12 and which has a substantially conical centering aid 16 in the center of its closed-walled cup bottom 15.
- the cup-like molding 14 is provided on its closed-walled lateral surface 17 with a reinforcing body 20 serving as a so-called backing part.
- This is essentially in the form of a circular cylinder and has a hollow peg-like receiving section
- the receiving opening 22 which is circular in cross section, engages over the lateral surface 17 of the cup-shaped projection 14.
- resilient tongues 23 serving as wall sections of the hollow pin, which are produced by cuboid-like recesses 24 in the jacket wall of the hollow pin, which are offset by 90 ° to one another and run along the lateral surface of the hollow pin, and form an annular sector. term cross-section.
- the resilient tongues 23 are provided at their free end, which serves as the tip of the tongue, with two spaced apart, radially extending stop elements 25, which with their outer stop surface 26 facing away from the receiving section 21 in the assembly stand of the reinforcing body 20 facing the heat insulation layer 12 Support the outside of the inner lining 13 and thus signal the correct end position during the assembly process of the reinforcing body 20.
