Problems solved by technology

If this happens, the tightness of the skirt cannot be guaranteed over its entire circumference and there is a risk that the insulation will still escape during foaming

Embodiment Construction

[0023] figure 1 The suction tube threading device shown in has a substantially tubular body 1 formed of solid plastic material, through which a hole 2 extends. On the end side of the bore 2 , the body 1 carries two ribs 3 extending radially over part of the circumference of the body. This end side is correspondingly provided for passing through the complementary shaped opening of the outer wall of the refrigerating appliance housing (not shown) from the foam material side and is then rotated in the direction of the arrow, thereby bringing the ribs 3 in their The beveled narrow sides 4 first slide over the edge regions of the outer wall surrounding the opening and finally clamp these edge regions only between the ribs themselves and an elastic skirt 5 . The substantially conical-shaped elastic skirt 5 has an outer diameter that is larger than the outer diameter of the opening in the outer wall, whereby the outer edge 6 of the skirt 5 rests continuously against the outer wall a...

Abstract

The invention relates to a component for assembly on an opening in a wall, comprising a component main body (1) and a flexible skirt (5), projecting from the main body (1), made from a more flexible material than the main body (1) and formed on the main body (1) in a sealing manner.

Description

technical field [0001] The present invention relates to a structural element for fitting to a wall behind which foam material is provided and a refrigeration appliance in which the structural element is used. Background technique [0002] Housings of refrigeration appliances, such as refrigerators, freezers or the like, are realized in a conventional manner as a hollow body with an outer wall and an inner wall which surround a cavity filled with insulating foam material. The insulating foam material is produced in the cavity in that a polymer material, in particular polyurethane, is loaded with pressurized gas, injected into the cavity and expanded in the cavity by the pressure of the gas. The urging by the expanding pressurized gas is responsible for spreading the foam all the way to the remote corners of the cavity and forming a closed insulating foam layer of uniform properties, which solidifies in the cavity. Housings with complex shapes and good thermal resistance can ...
