Definitions

• the present invention relates to a refrigerator with an interior enclosed by a heat-insulating housing and at least one refrigerated goods rack arranged in the interior.
• a refrigerated goods rack it can e.g. are a shelf or pull-out box mounted in the body of the refrigerator, or a door rack mounted on the inside of the door.
• a protective or decorative strip to the edge. If the edge has a curved course, the bar must follow this course.
• To produce the strips with different radii of curvature in accordance with the curvature of the edge on which they are to be mounted is very time-consuming and accordingly expensive.
• Extruded stiffening or decorative strips made of plastic are also known, which, in order to give them a metallic appearance, are laminated with a shimmering metallic hot stamping foil.
• extruded strips are generally straight-lined and, after extrusion, cannot be bent permanently afterwards without considerable effort in order to adapt them to the radius of curvature of the edge of a refrigerated goods rack to which they are to be attached.
• the object of the present invention is to provide a refrigerator in which a likewise curved strip is attached to a curved edge of a refrigerated goods rack, and which can be implemented simply and inexpensively with a small number of tools.
• the strip attached to the curved edge of the refrigerated goods rack is constructed from a plastic core and a metallic jacket, the jacket surrounding the plastic core in a curved cone. 200400358
• Such a bar can be comparatively easily first made in a straightforward configuration and then curved to match the course of the edge. While the plastic material of the core is generally only elastically deformed by such a curvature, a plastic deformation takes place on the metal of the casing, which, when the curving force is no longer present, remains and prevents the plastic core from returning to its rectilinear configuration.
• the bar In order to ensure a tight fit of the bar on the edge of the refrigerated goods rack and / or to effectively protect the edge from damage, the bar preferably has a groove into which the curved edge of the refrigerated goods rack is inserted.
• the structure of the bar made of plastic core and metallic shell allows a curvature with a radius of curvature transverse to the depth direction of the groove without significant twisting of the bar.
• the groove preferably has a width that increases at least in places from an input region of the groove toward its bottom.
• the metallic jacket preferably has a material thickness of 0.1 to 0.3 mm, preferably approximately 0.2 mm.
• the strip with a plastic core and a metallic jacket is preferably produced by coextrusion. In this way, long, straight strips can be obtained in a simple manner, which only have to be cut to the length of this edge for attachment to an edge of a refrigerated goods rack and have to be curved according to their radius of curvature.
• FIG. 1 is a perspective view of a door rack for a refrigeration device according to the invention.
• FIG. 2 shows an enlarged section through the door rack of FIG. 1 along the line II- ⁇ ;
• FIG. 3 shows an enlarged detail of the door rack.
• Fig. 1 shows a perspective view of a door rack for a refrigerator according to the invention with a one-piece injection molded plastic box 1.
• the open top of the box 1 has a bottom 2, a rear wall 3 facing the door of the refrigerator in the assembled state, one the curved front wall 4 facing the interior and side walls 5, each of which is divided by a step 6 into a section adjacent to the refrigerator door and a section away from the refrigerator door.
• a step 6 In the assembled state of the 200400358
• Door racks are formed on the inside of the refrigerator door formed vertical ribs on the door-near portions of the side walls 5, and projections formed on the ribs engage in downwardly open and upwardly closed grooves 7 of the door-near portions to support the door racks.
• a bead 8 with an approximately three-quarter circular cross section is formed on the upper edge of the front wall 4.
• a stiffening and decorative strip 9 is locked onto this bead 8 by the bead 8 being received in a groove 10 in the strip 9.
• the groove 10 itself has an approximately circular segment-shaped cross section, which extends over an arc of more than 180 °, so that the groove 10 is narrower in its entrance area than at its widest point.
• the strip 9 consists of a core 11 made of a plastic material, which can be the same material as the box 1, and a jacket 12 made of metal, which essentially covers the visible outer surface of the strip 9.
• the strip 9 is produced by coextrusion of the metallic shell 12 with the core 11, a straight strip being obtained first. A piece cut from this straight bar in the length required for the front wall 4 is then bent to the radius of curvature corresponding to the curvature of the front wall 4. This bend leads to a plastic deformation in the metal of the jacket 12, while it is still largely elastic in the plastic of the core.
• the thickness of the metallic sheath is chosen at about 0.2 mm so that the strip 9 counteracts after bending. e a possible restoring force of the core 11 maintains its curved configuration.
