Description

Technical field

The present invention relates to a refrigerator with an internal cavity surrounded by a heat insulating casing, and at least one device for storing refrigerated products located in the internal cavity.

State of the art

Such a device for storing refrigerated products may be, for example, a container, shelf or drawer mounted in the refrigerator body, or a door shelf mounted on its door. To stiffen the free edge of such a device for storing refrigerated products, to protect it from damage or simply for aesthetic reasons, it is desirable to install a protective or decorative strip on the edge. If the edge has a curved shape, the bar should follow this shape. The manufacture of strips with different radii of curvature corresponding to the curvature of the edges is very laborious and accordingly expensive. In principle, of course, it is possible to produce such a curved strip with a radius of curvature corresponding to the edge on which the strip should be installed using injection molding, but for this radius of curvature special injection molds will be required.

Extruded stiffening plates and decorative planks made of plastic are also known, which, to give them a metallic appearance, are glued with a hot stamping film with a metallic sheen. However, such extruded planks are usually straightforward and require significant costs to give them a stable curvature after extrusion, corresponding to the radius of curvature of the edge of the device for storing refrigerated products on which they should be installed.

It is also known to install on the free edge of a device for storing refrigerated products, in particular shelves, stiffeners or decorative strips consisting entirely of metal. However, such a bar, made in most of the continuous casting method, is also straightforward and it is difficult to bend it in accordance with a curved edge so that it does not simultaneously twist during bending.

Disclosure of invention

The objective of the invention is to create a refrigerator in which a curved strip was also installed on the curved edge of the device for storing refrigerated products and which can be simply and cheaply implemented using few tools.

This problem is solved in that the bar installed on the curved edge of the device for storing refrigerated products consists of a plastic core and a metal shell, and the shell retains the curvilinear configuration of the core. Such a bar can be relatively simply made first in a straight configuration, and then curved in accordance with the curvature of the edge. While the plastic core undergoes, as a rule, only elastic deformation under this bending, the shell metal deforms plastically, retains a bent shape after the cessation of the bending force, and prevents the plastic core from returning to a rectilinear configuration.

In order to ensure that the strip is firmly fixed to the edge of the device for storing refrigerated products and / or to effectively protect the edge from damage, a groove is preferably provided on the strip in which a curved edge of the device for storing refrigerated products is inserted.

The execution of the plank from a plastic core and a metal shell allows bending with a radius of curvature directed across the depth of the groove without noticeable twisting of the plank.

In order to secure the strip by snapping it on the edge, the groove, at least in some places, expands in the direction from the entrance of the groove to its bottom.

The thickness of the metal shell is preferably from 0.1 to 0.3 mm, and most preferably about 0.2 mm. A plank with a plastic core and a metal sheath is preferably made by co-extrusion. With this method, long straight strips can be easily obtained, for the installation of which on the edge of the device for storing refrigerated products you only need to cut them along the length of the edge and bend it in accordance with its radius of curvature.

Brief List of Drawings

Other features and advantages of the invention arise from the following implementation example with reference to the accompanying drawings, in which:

figure 1 is a perspective view of a door shelf for a refrigeration apparatus according to the invention;

figure 2 is an enlarged section of the door shelf of figure 1 along the line II-II; and

figure 3 is an enlarged detail of the door shelf.

The implementation of the invention

In Fig. 1, a perspective view shows a door shelf for a refrigerator according to the invention with a plastic box made of plastic by injection molding as an integral part 1. The top box 1 open has a bottom 2, a rear wall 3 facing the refrigerator door in a mounted state , a curved front wall 4 facing the inner cavity, as well as side walls 5, each of which is divided by a step 6 into a part closest to the refrigerator door and a part farthest from the refrigerator door. In the mounted state of the door shelf, the vertical ribs formed on the inside of the refrigerator door are adjacent to the parts of the side walls 5 proximal to the door, and the protrusions formed on the ribs enter the openings from the bottom and closed on top of the grooves 7 of the parts adjacent to the door, serving as a support for the door shelf.

As is particularly clearly seen in the sections shown in FIGS. 2 and 3, a bulge 8 is formed on the upper edge of the front wall 4, the cross section of which is approximately three quarters of a circle. A decorative strip 9 is put on this thickening 8, which simultaneously serves as an element of rigidity. In cross section, the groove 10, like the strip 9 itself, has the shape of a circular segment spanning an arc of more than 180 °, so that the groove 10 in the entrance is narrower than at its widest point. The strip 9 consists of a plastic core 11, which can be made of the same material as the box 1, and a shell 12 of metal, which practically covers the visible outer surface of the strip 9. The strip 9 is made by co-extrusion of a metal shell 12 with a core 11, moreover at first a straight bar is obtained. Then, a piece cut from this rectilinear strip with the length required for the front wall 4 is bent with a radius of curvature corresponding to the bend of the front wall 4. In this bending, the metal of the sheath 12 undergoes plastic deformation, while the deformation of the core plastic still remains substantially elastic. The thickness of the metal shell selected about 0.2 mm, so that the strip 9 after bending maintains a curved configuration in spite of the possible rectifying action of the core 11.

This method allows you to use the same profile, made by the method of joint extrusion, for the manufacture of strips 9 to numerous models of door shelves with different radii of curvature of the front wall 4.
