Definitions

• the present invention relates to an inner container for a refrigeration device, in particular a household refrigerator.
• Internal containers of refrigerators are conventionally deep-drawn, a technique that is economical but does not allow for high manufacturing accuracies and complex shapes.
• To attach mounting parts such as interior doors, flaps, refrigerated goods or the like, it is therefore common to holders for such

• Leaks can get into the interior of the inner container.
• brackets with flexible aprons, which nestle during assembly around an opening on the foam side of the inner container.
• brackets are quick and easy to install, they must be handled carefully during installation and before to prevent damage to the aprons.
• Inner container is not pierced, but only a pin during the
• the object of the invention is to provide an inner container for a refrigeration device, which allows a secure, fixed installation of built-in parts and is inherently safe against the ingress of foam.
• the object is achieved by forming an undercut in an inner container for a refrigerator with a storage compartment surrounding walls and at least one tightened in one of the walls hollow pin on an inner surface of the pin.
• an undercut which is deep enough to provide a secure fit to a part inserted into the pin can be obtained by deep drawing and in particular in one operation with the formation of the inner container from flat material.
• the undercut excludes that the pin can be provided with a usual during deep drawing draft angle.
• small dimensions of the pin allow forced removal. It can be seen that a depth of the undercut of 0.2 to 0.5 mm is sufficient to provide firm support to a part inserted into the post.
• the undercut is formed by a plurality of spaced apart in the circumferential direction of the pin spaced on the inner surface projections. This allows the spigot, when inserting a part, the the inside of the pin to the

• the introduced into the pin and locked in the undercut part may be in particular a holder for a built-in part of the inner container such as a door, a flap, a refrigerated goods or the like.
• An engaging in the cavity of the pin pin such a holder preferably has at least one circumferentially circumferential rib in order to attack at any point of its circumference on one of the inner projections of the pin can.
• the pin preferably comprises at least two tongues separated by a longitudinal slot. By being pressed against each other under narrowing of the longitudinal slot, the pin can, upon insertion into the pin, the projections, and the rib can engage behind the projections in the undercut.
• Two pins arranged in mirror image with respect to one another and spaced apart from each other can each accommodate an axis of rotation or a bolt of a door. Since each pin is suitable both for receiving the axis of rotation and for receiving the door, a stop change of the door is readily possible.

• Inner container 1 is divided into two storage compartments, a larger, lower cooling compartment 2 and an overlying, smaller freezer compartment 3.
• both compartments have a common, not shown outside door; the freezer compartment 3 is separated by partition wall 6 and an inner door 4 from the refrigerating compartment 2 and insulated from it.
• the inner door 4 is shown in the open position; in the closed position is a frame-shaped on an inner side of the inner door 4 extending elastic seal 5 at a front edge of the intermediate wall 6 and a step 7, which is in a same plane with the front edge of the intermediate wall 6 on side walls 8 and 9 ceiling along the freezer compartment 3.
• FIG. 1 Side walls 8 two in Fig. 1 of the frame 10 concealed hollow cylindrical pin 1 1 formed, one of which is shown in Fig. 2 in an enlarged view.
• One of these two mutually mirror-inverted pin 1 1 is provided to fix a pivot pin defining the pivot axis of the inner door 4; the other takes in the closed position of the inner door 4 a latch 12 (see Fig. 1) to fix the inner door 4 in the closed position.
• the latch 12 is displaceable in a vertical channel of the inner door 4 by a lever 13 accessible on the lower edge of the door 4 in order to open the door 4.
• a corresponding channel on the opposite edge of the door 4 receives the hinge pin.
• the two channels are identically shaped so that the latch 12 and the hinge pin are interchangeable, and also the lever 13 is mountable in two different, with respect to a vertical center plane mirror-image positions to the bolt 12 in any mounting position, in the left or in the right Channel, press.

• Projections 18 distributed.
• the projections 18 are divided into two groups of three projections, wherein the projections 18 of a same group are distributed uniformly over the circumference of the pin 1 1 and the groups are staggered in the longitudinal direction of the pin 1 1.
• the projections 18 of different groups are arranged offset in the circumferential direction against each other, so that a projection 18 of the one group is placed in the circumferential direction in each case between two projections of the other group.
• the projections 18 are impressions of recesses of a mandrel, which is extended during deep drawing of the inner container 1 from a freezer compartment 3 forming punch. For the impression of the projections 18 it is sufficient to press from the outside a flexible mold such as a liquid-filled pad against the inside of the mandrel supported pin 1 1. As long as the projections 18 not too far into the interior of the pin 1 1 project, the mandrel can be easily withdrawn after molding the projections 18 in the stamp of the freezer compartment; the surface of the punch substantially perpendicular to the direction of movement of the mandrel, at the moment of withdrawal, supports the cover 9 around the pin 1 1 so that the pin can be released from the pin 11 without deforming the cover 9 unacceptably.
• Fig. 3 illustrates the use of the two pins 1 1 on the basis of a section parallel to the front of the inner container 1.

Each rib 25 engages behind a group of projections 18. A projection of the projections 18 over the surrounding inner surface of the pin 1 1 of 0.2, better 0.3 mm is sufficient to ensure a secure grip of the ribs 25.
• the ribs 25 on its side remote from the head piece 21 a conically tapered flank 26. A the head piece 21 facing flat edge 27 engages behind the projections 18 and ensures a tight fit ,

To assemble the door 4, it is sufficient to press it into the compartment 2 from the open front of the inner container. In this case, the hinge pin 20 comes into contact with an inclined end face 34 of the holder 19 and is pressed into the channel 33. As soon as it reaches the central recess of the holder 19, the hinge pin 20 is pressed by the spring into the recess and locked in it.
