Description

The present invention relates to a built-in part for a refrigeration appliance, in particular for a household refrigeration appliance, such as a door rack or a drawer.

Out DE 10 2009 028 435 A1 a door rack is known, the main body has a front wall on which various types of decorative profiles can be mounted. One of these decorative profiles includes a plate that completely covers the front wall of a body. Manufacturing inaccuracies can lead to the fact that the plate of the decorative profile on the front wall of the body is not fully applied. While the upper corners of the decorative profile are fixed by a tongue and groove engagement, in particular, the lower corners of the plate tend to stand out from the wall of the body. This not only provides an aesthetically unsatisfactory sight to the user, it also affects the tightness of the decorative profile.

Out DE 10 2004 012 497 A1 For example, a door rack is known, in which a decorative profile plugged onto the upper edge of a front wall is formed by co-extruding a metallic shell with a plastic core. Unlike a plastic profile that has only a thin superficial metallization, such a coextruded decorative profile is hardly distinguishable from a pure metal profile not only visually, but also by the sense of touch, since the relatively thick metal layer of the co-extruded decorative profile feels as cold as a pure metal object. If such a coextruded decorative profile has large cross-sectional dimensions of the order of several cm, there is the problem that due to different coefficients of thermal expansion of the coextruded materials, the decorative profile tends to warp. Therefore, it is difficult for such a co-extruded decorative profile, the cross-section to produce so accurate that the profile rests against the wall of a door compartment over its entire surface.

US 5,370,454 discloses the features of the preamble of claim 1. It discloses a drawer which is movable on guide rollers in guide rails. The drawer has opposite sides on which locking elements are positioned. A trim profile member has flanks which cooperate with the locking members to releasably disengage the trim profile member to attach to the drawer.

US 5,536,540 discloses a body side molding for automobiles. The molding has a rigid base and a cover that is relatively flexible relative to the base. The base and the cover snuggle together. The cover has holders on its back and the base has holders for mating with the holders of the cover on its top. The back of the base is attached to a vehicle by means of double-sided adhesive tape.

The object of the invention is to provide a built-in part for a refrigeration device, which can ensure a tight fit of a decorative profile in a reproducible position, even with large cross-sectional dimensions of the decorative profile.

The object is achieved with the features of claim 1 by the wall plate is limited relative to its free edge by an undercut edge at a built-in with at least one wall plate having a free edge and a decorative profile attached to the free edge and the decorative profile covering a wall plate Has main plate and engaging in an undercut of the undercut edge locking contour.

The free edge is received in a groove of the decorative profile which is open towards the catch contour. It may be rotationally fixed in the groove or pivotally received about an axis extending in the direction of the free edge.

The wall plate has a recess on its side facing the main plate of the decorative profile, and in a partially mounted position of the decorative profile, on the one hand, the free edge engages in an input region of the groove and the detent contour into the recess. Thus, the decorative profile can be pre-assembled stress-free on the wall plate to be subsequently moved by pressing the groove on the free edge of the wall plate in a stop position in which the locking contour can embrace the undercut edge.

At one of the undercut edge side facing the recess is preferably limited by a slope. This ensures that when the groove is pressed onto the free edge of the wall plate, the locking contour slides out of the recess.

In order to save material and weight, the wall plate may have ribs engaging in the recess.

In particular, the slope may be formed by distributed in the width direction of the wall plate ribs.

Preferably, the decor profile consists at least partially, in particular on its visible surfaces, of metal, in particular of aluminum. It can be made entirely of aluminum, preferably it also has a plastic content.

It is particularly preferred that the decorative profile comprises coextruded layers of metal and plastic. A coextruded layer of metal may be 0.2 gauge thick mm or above be strong enough to contribute significantly to the rigidity of the decorative profile, so that the decorative profile not only fulfill aesthetic tasks, but can also increase the stability of the insert.

The built-in part may in particular be a door rack, but also an extract box.

A door racks 1 according to the present invention comprises a base body 2 in the form of an elongated, approximately cuboidal, open-topped box carrying at its end faces 3 (in a conventional manner not shown here) contours for anchoring to the inside of a refrigerator door, and a decorative profile 4, which is latched onto a front wall 5 facing away from the refrigerator door of the base body 2. Fig. 1 shows such a door rack 1 partly in perspective view, partly cut along a plane which can extend parallel to the end face 3 through the front wall 5, a bottom plate 6 and a rear wall 7 of the base body 2.

The main body 2 can be injection molded in one piece of plastic, also conceivable is a multi-part structure, in particular one in which the walls 5, 7 and the bottom plate 6 are integrally connected and firmly connected to the end faces 3 by gluing, latching or the like.

The decorative profile 4 comprises a main plate 8, at the upper and lower edge of each webs 9, 10 are angled towards the rear wall 7 out. The web 10 carries a detent 11 which is engaged in a complementary undercut 12 at the lower edge of the front wall 5.

From a rear edge of the web 9 from a further web 13 extends downwards and forms with the upper portion of the main plate 8 downwardly to the web 10 toward open groove 14 into which an upper edge 15 of the front wall 5 engages positively. In a lower region of the front wall 5 extends over the entire width of a recess 16. The depth of the recess 16 corresponds to the extension of the web 10 in the depth direction.

Fig. 2 shows the base body 2 without the decorative profile 4. The surface of the front wall 5 jumps behind leading edges 17 of the end faces 3 to the wall thickness of the decorative profile 4, so that the outer surface of the decorative profile 4, if this is correctly mounted, with the leading edges 17 is flush , The recess 16 is bounded at its lower edge by a plurality of over the width of the front wall 5 distributed triangular ribs 18th

Fig. 3 Although it would be conceivable in principle to postpone the decorative profile 4 before attaching the end faces 3 in the width direction on the front wall 5, but faster and easier is in Fig. 3 illustrated sequence. In a first stage, the decorative profile 4, as in the left illustration of Fig. 3 shown arranged on the front wall 5 so that the web 10 engages in the recess 16 and the main plate 8 a portion 19 of the front wall 5 above the recess 16 contacts. The height of the region 19 is slightly smaller than the distance between the web 10 and a lower edge 20 of the web 13, so that the decorative profile 4 can be brought into the position shown, without having to be elastically deformed.

From this position, the decorative profile 4 can be pushed freely down, with first, as seen in the second view from the left, the web 10 moves downward within the recess 16 and the upper edge 15 of the front wall 5 a piece into the groove of the decorative profile 4 engages. The upper edge 15 is held in the groove 14 positively and rotationally fixed when the web 10 reaches the ribs 18. If the decorative profile 4 now pressed further down, as shown in the third illustration from the left, then the web 10 is pressed by the ribs 18 to the outside, and the main plate 8 is elastically bent.

The decorative profile 4 finally reaches a stop position in which the lower edge 20 abuts against a shoulder 21 on the inside of the front wall 5. At the same time, the web 10 has passed a portion 22 of the front wall 5 below the recess 16 and is driven by the elastic tension of the main plate 8 in a recess 23 which extends between a lower edge of the front wall 5 and the bottom plate 6. In this recess 23, the undercut 12 is formed, in which the locking lug 11 engages to firmly anchor the decorative profile 4.

If the decorative profile 4 is slightly deformed by internal material tension, it may be necessary to press against it from the outside slightly to bring the locking lug 11 in the undercut 12 for locking. As soon as this is done, however, the decorative profile 4 is fixed positively and without play, and a more uniform, aesthetically satisfactory connection of the decorative profile 4 to the end faces 3 is ensured.

The decorative profile 4 may be integrally extruded from plastic or metal, in particular aluminum or stainless steel, a plastic profile may be provided with a surface metallization in order to give the decorative profile 4 a metallic appearance. According to a preferred embodiment, however, the decorative profile 4 is made of aluminum and plastic coextruded, as in Fig. 4 shown in a cross section. For this purpose, an aluminum strip is roll-formed onto a cross-section, which it should also have in the finished decorative profile 4, and passed through a nozzle together with the plastic material to be co-extruded. The aluminum strip on the finished decorative profile 4 forms an outer layer 24 of preferably 0.2 to 0.4 mm thickness, which conceals a plastic layer 25 stiffening it inside. The outer layer 24 extends to end faces 26, 27 of the profile 4, which, when the decorative profile 4 is mounted on the base body 2, invisibly disappear inside the store. The plastic layer 25 can therefore be visible at the finished assembled door rack 1 at any point.

Fig. 5 shows a preferred embodiment of the main body 2. According to this development, extending over the recess 16 portion 19 of the front wall 5 is formed by a interior of the door compartment facing base plate 28, from the vertically elongated, similar to the ribs 18 across the width of the wall 5 distributed ribs 29 protrude. Vertex surfaces of the ribs 29 support the main plate 8 when the decorative profile 4 is mounted.

The design of the Fig. 6 is different from those of Fig. 1 to 5 in two independently realizable aspects. The first concerns the type of fixture on which the decor profile is mounted. In case of Fig. 6 it is a drawer, of which a schematic cross section through a front wall 5 is shown.

The second aspect relates to the attachment of the decorative profile 4 on the front wall 5. In the case of Fig. 6 For example, the upper edge 15 of the front wall 5 has a rounded cross-section which engages in a circular sector-shaped groove 14 of the decorative profile 4. As a result, the decorative profile 4 is pivotable about an axis defined by the upper edge 15 between one in the Fig. 6 shown as a hatched and solid bound cross-section shown partially assembled position and a dashed bordered cross-section shown, fully assembled position. As in the previously described embodiments a provided with a latch 11 web 10 of the decorative profile 4 in the finished assembled position in an undercut 12 at the lower edge of the front wall 5 a. The decorative profile 4 is extended beyond the web 10 down through a portion 30 which defines a downwardly open handle recess 31 in the assembled position, in which a user can engage to pull the drawer from a storage compartment of the refrigerator.
