Definitions
- the present invention relates to a heat-insulating wall, in particular a wall that is part of a door or a housing of a refrigerator.
- Such walls conventionally comprise an insulating layer of low strength, which is delimited by at least one firm skin. If parts have to be fastened to such a wall, for example a handle on a refrigerator door or refrigerated goods carrier in the body of the refrigerator, this is often done with backing parts anchored in an opening in the skin, which locally distribute a force exerted by the assembled part into the skin , so that it is able to bear the force despite a low material thickness.
- a heat-insulating wall according to the preamble of claim 1 is known from EP 1 032 795 B1.
- the backing part is fastened in the manner of a bayonet coupling to the outer skin of a refrigerator door, by inserting it into the opening from a first side of the skin and rotating it around the insertion direction into a locked position, in which a contact surface of a retaining wing of the backing part on a second , opposite side of the solid skin, a second contact surface of the backing part rests on the first side of the solid skin, so as to immobilize the backing part in the insertion direction, and a stop flank of the backing part strikes an edge of the opening which is radially oriented with respect to the insertion direction ,
- the distance between the two contact surfaces must be adapted exactly to the thickness of the firm skin. If the distance is too large, the backing part will not find a firm hold; if it is too small, it is impossible to turn the backing part into the locked position.
- the object of the present invention is to further develop this known heat-insulating wall so that a higher tolerance with regard to fluctuations in the thickness of the skin or the distance between the two contact surfaces is achieved.
- the contact surface of the retaining wing merges materially into the stop flank
- a flexibility of the retaining wing in the insertion direction is achieved in the wall according to the invention in that a material taper is provided between the retaining wing and the stop flank. Due to the weakening of the material thickness between the retaining wing and the stop flank, elastic behavior is achieved to a certain extent for the retaining wing. If the backing part is to be mounted on a firm skin, the thickness of which is slightly greater than the distance between the two contact surfaces, the retaining wing can yield slightly in the direction of insertion, and the backing part can be brought into the locked position and remains stable therein.
- the elastic behavior of the holding wing can be determined particularly easily by designing the material taper as a gap or slot in an application-oriented manner.
- the first side of the skin faces the insulation layer, so that on the finished wall the backing part is essentially embedded in the insulation layer.
- the backing part is preferably immobilized in the insulating foam in the locked position.
- a sealing lip of the backing part which extends around the opening and lies against the first side of the skin, can serve to prevent the material of the insulation layer from entering the opening.
- This sealing lip can also serve as the second contact surface of the backing part.
- the backing part is preferably separated from the insulation layer by a cup placed over the backing part, an edge of which bears against the first side of the skin.
- This edge can in turn preferably be designed in the form of a conical sealing lip.
- the cup does not have to bear the weight of an element engaging the backing part, but essentially only serves to shield the opening from the insulation layer, it can advantageously be formed from a more flexible material than the backing part. This flexibility favors an effective seal against the insulation layer between the firm skin and the rim of the cup.
- the cup is provided with wings projecting into the insulation layer for immobilizing the backing part.
- the backing part and the cup are preferably locked against one another in a rotationally fixed manner, preferably in that the backing part and cup have at least one groove oriented in the insertion direction and the other each has a complementary rib to the groove.
- FIG. 1 shows a refrigerator door as an example of a heat-insulating wall according to the invention, with a door handle fastened to the door with the aid of a backing part;
- Fig. 2 is an exploded perspective view of the backing member and a cup separating the backing member from the insulation layer;
- Fig. 3 is an enlarged view of the backing part
- Fig. 4 is a perspective view of the backing part and the cup in the assembled state.
- Fig. 1 shows a refrigerator door 10, which by a non-cutting shape Plastic lining produced inner lining 11, a heat insulation layer 12 and an outer lining 13 which is connected to the inner lining 11 to form a door body and serves as the outer skin 13, which due to the wetting effect of the foaming of polyurethane in the space delimited by the inner lining 11 and the outer skin 13 formed insulation layer 12 is connected to the inner lining 11 to form a rigid structure.
- a bow-shaped door handle is fixed at two fastening positions I and II, of which the fastening position I is provided on the side walls of the outer skin 13 which run vertically in the installed position of the refrigerator door 10, while the fastening position II is approximately in the center Width of the door 10 is provided on the front side formed by the outer skin 13.
- the outer skin 13 formed from steel sheet without cutting is provided for this purpose with a substantially circular opening 14, in the opening area of which two at least approximately opposite one another, projecting integrally with the projections 15 integrally formed on the outer skin, which protrude are gradually offset towards the heat insulation layer 12 by cranking.
- Adjacent to the offset projections 15 are serving as latching means 16, opposing fixing and holding lugs, which, like the projections, but in contrast to these, are made flat with the rest of the outer skin 13.
- a backing part 20 provided for insertion into the opening 14 and locking in the manner of a bayonet lock is in one piece, essentially by means of a hollow cylindrical shaft 21, a base plate 22 largely closing the shaft 21 at one end and a base plate 22 extending around the shaft 21 , frustoconical sealing lip 23 is formed.
- a cross-shaped opening 24 in the base plate 22 is provided for anchoring the door handle therein.
- two circular-arc-shaped ribs 25 protrude from the base plate 22 in the axial direction. From the ribs 25 there are in turn two retaining wings 27 spaced from the plate 22 to form a groove 26 and two latching noses 29, 30 delimiting a radial recess 28.
- the backing part 20 is provided in order to be inserted into the opening 14 of the outer wall 13 from its inside in a rotational orientation, in which the retaining wings 27 and locking lugs 29 of a rib 25 are each in a cutout 17 between one of the projections 15 and a fixing and holding nose 16 engage. If, after this insertion, the inside of the projection 15 bears against the base plate 22 of the backing part 10, the latter can be rotated in the opening 14 into an orientation in which in each case one stop face of each retaining wing 27 facing the base plate 22 bears against an outside of the projection 15.
- the fixing and holding lugs 16 each have to engage in one of the recesses 28 of the backing part, ie the backing part 20 must be turned so far that the fixing and holding lugs 16 each have the Pass locking lug 29, which lies between the retaining wing 27 and the radial recess 28.
- the freedom of rotation of the backing part 20 is limited in that a radially oriented flank 34 (see FIG. 3) of the locking lug 29 facing the retaining wing 27 abuts against a radially oriented edge 18 of the projection 15.
- a radial slot 31 formed between this flank 34 and the retaining wing 27 increases the elastic deformability of the retaining wing 27 when the backing part 20 is screwed onto an outer skin 13, the wall thickness of which is slightly larger than the width of the groove between the retaining wing 27 and the base plate 22, and while the fixing and holding lug 16 shortly before the latching the recess 28 passes the latching lug 29.
- the presence of the slot 31 also ensures that the torque required to turn the backing part onto the outer wall does not increase the closer the radial edge 17 comes to the flank 34.
- the outer edge of the conical sealing lip 23 presses elastically against the inside of the outer skin 13 over its entire circumference. If the material of the sealing lip 23 were sufficiently flexible, this could be the case Sealing lip 23 already provide adequate protection against the passage of foam from the space into the interior of the backing part 20 (and thus possibly to the outside of the door). In order to provide a robust anchoring for the door handle, however, the material of the backing part 20 must be quite stiff, so that it is difficult to guarantee that the sealing lip 23 is completely foam-tight.
- the shaft 21 of the backing part 20 is provided with a circumferential rib 32 (FIG. 3), to which a complementary circumferential groove 42 is formed on the inside of the cup 40.
- Cup 40 and backing 20 are also rotatably Provided by means of two diametrically opposite ribs 33 of the shaft 21 and grooves 43 of the cup 40 which extend in the push-on direction.
- the cup 40 is at the level of its base with a flange 44 oriented transversely to the plugging direction and with a plurality of wings 45 which extend radially and parallel to the plugging direction with respect to the axis of the cup 40 Mistake.
- the cross-shaped opening 24 of the backing 20 fixedly mounted in the outer skin 13 is provided in order to insert an approximately T-shaped anchor of the door handle into the vertical slot of the opening 24 and then the shaft of the anchor into one of the two of the vertical To shift slit outgoing horizontal branches of the opening 24, wherein the crossbar of the anchor held by the shaft engages above and below the branch behind the base plate 22 of the backing 20.
- the armature is displaced depends on which the other end of the door handle at position I is attached to the two side cheeks of the outer skin 13.
- cross-shaped opening 24 in the base plate 22 of the backing part 20 can be replaced by any other shapes suitable for fastening the desired part in order to fasten any other parts.
- a backing part 20 of the type described above can also be used to be mounted in an opening of the inner lining 11, in order to attach to this backing part 20 refrigerated goods carriers of the interior of the refrigerator or telescopic rails on which such a refrigerated goods carrier can be moved.
