Problems solved by technology

Therefore, in the known solution, the production cost is very high
In addition, the liner must be penetrated at one or more points, which impairs the thermal isolation properties

Embodiment Construction

[0023] FIG. 1 shows a cross-sectional view of a mounting device in, for example, a lining or an inner wall 1 of a cooling and / or freezing plant. On the outside of the inner wall 1 a foam insulation 3 is arranged in a manner known per se. A receiving contour 15 formed in the plastic inner wall 1 fits positively into the fastening part of the pull-out rail 5 , which is shown here in cross-section. In the pull-out rail 5 held by a form-fitting connection with, for example, a flange 13, the movable pull-out rail 7 with support means 9 for a pull-out tray or a pull-out drawer is moved by means known per se, such as ball bearings or The other roller bearings move the bearings.

[0024] The pull-out guide rail 5 is mounted substantially flush, enabling easy cleaning of the inner wall 1 . Since the draw-out rail 5 is accommodated in the inner wall 1 , the space available in the cooling chamber is increased and is visually more pleasing than in the case of mounting the draw-out rail ...

Abstract

Disclosed is a method for producing a fastening system for fixing elements on the plastic lining (1) of a refrigerator and / or freezer wall that is thermally insulated by means of foam. According to the inventive method, the lining is deep-drawn from a plastic material with a receiving contour (15) which is embodied so as to partly correspond to the outer contour of the element that is to be fixed such that the element that is to be fixed can be accommodated by the receiving contour, and the element that is to be fixed can be placed therein. Alternatively, the element that is to be fixed is inserted into a deep-drawing die, and the lining is deep-drawn from plastic material so as to at least partly mold the element that is to be fixed in order to form a receiving contour in the plastic lining for the element that is to be fixed. In both instances, a thermal insulation made of foam (3) is then foamed onto the rear face of the plastic lining.

Description

technical field [0001] The invention relates to a method for producing a mounting device for mounting elements, in particular pull-out rails, on the plastic lining of foam insulation walls of cooling and / or freezing plants, a mounting device and a Mounting method for mounting elements on the inner lining of a foam insulation wall of a cooling and / or freezing plant, and a cooling and / or freezing plant having withdrawable rails mounted by means of the The device is installed on the inner liner. Background technique [0002] In particular, in the construction of cooling and / or freezing plants, thin-walled inner linings made of plastic are used as inner and outer walls, the space between inner and outer walls being formed by foaming between these walls Foam for thermal insulation. Rails, for example for supporting discs or other fastening elements, are mounted on the inner wall. When installing heavy elements, stability problems arise due to the thin-walled design of the lini...
