Definitions

• the present invention relates to a refrigerator, in particular a household refrigeration appliance such as a refrigerator and / or a freezer, with a storage chamber from which at least one drawer is pulled out.
• a refrigerator in particular a household refrigeration appliance such as a refrigerator and / or a freezer, with a storage chamber from which at least one drawer is pulled out.
• Object of the present invention is to provide a refrigeration device in which different mounting positions of pull-out boxes in a simple, cost-effective manner can be realized.
• the object is achieved by an adapter element is provided in a refrigeration device with two side walls delimiting a bearing chamber and two each adjacent to one of the side walls extending primary guide rails for pull-out boxes, which is fastened to one of the primary guide rails and has a secondary guide rail in the fortified Condition parallel to the primary guide rails between them runs.
• the adapter element is mirror-symmetrical so as to be selectively attachable to either of the two primary guide rails adjacent the left or right side wall of the storage chamber.
• Such a mirror symmetry is preferably based on the fact that a mirror symmetry plane of the adapter element is perpendicular to its secondary guide rail.
• To the refrigeration device should also include at least one drawer box, which is guided on at least one of the guide rails, primary or secondary, in the depth direction of the storage chamber movable.
• At least each primary guide rail preferably also the secondary guide rail, a stop should be assigned, which limits the freedom of movement of this guided guide rail extension box in the depth direction of the storage chamber to prevent the pull-out box is accidentally pulled completely out of the storage chamber.
• the stops of the primary guide rails if one of them carries the adapter element, can be conveniently used to lock the adapter element thereto.
• a stop at a rear end of a primary guide rail is not usually necessary to limit the freedom of movement of the pull-out box into the storage chamber, in the context of the present invention, however, it can be used to lock the adapter element to it, if necessary , By being attached to two stops at both ends of a guide rail, it is strong and largely secure against overstressing by bending.
• a locking projection may protrude beyond the front or rear end of one of these walls. If the groove extends beyond the locking projection extends, then cooperating with the locking projection projection on the primary guide rail can be formed laterally.
• the latching projection may be formed as a hook.
• the latching projection preferably has the shape of an arc whose two ends are connected to a front or rear edge of a wall of the adapter element.
• the secondary guide rail should also have a stop at both ends so that in each mounting position, on the left or right primary guide rail, a stop of the secondary guide rail facing the door and thus is effective to prevent accidental withdrawal of the pull-out box.
• the above-mentioned first pull-out box may extend over a majority of the width of the storage chamber and be guided on the secondary guide rail and the respective remaining primary guide rail; According to a preferred development, the first pull-out box is narrower, so that next to it a second pull-out box can be placed so that one of the pull-out boxes is guided on the secondary guide rail of the adapter element and the other on the left-hand primary guide rail. Simultaneous guidance on two guide rails is not required to restrict the mobility of the pull-out boxes to a pure displacement in the depth direction of the storage chamber.
• both pull-out boxes can each have two guide contours complementary to the guide rails, in order to be able to couple each of them selectively to the secondary guide rail or to the respective primary guide rail which is left free, depending on the installation position of the adapter element.
• the primary guide rails can be arranged on a shelf which divides the storage chamber into compartments lying one above the other.
• a shelf is feasible in a simple manner in the form of a frame framed by a frame, preferably a plastic injection-molded frame in one or more parts.
• the primary guide rails can be designed to save costs as part of the frame.
• a bottom panel of an extension box carried by the shelf may have in a rear area a contact surface contacting the panel, for example in the form of Runners, and in a front area, which moves when pulling out of the pull-out box over the front edge of the shelf, lie above the contact surface.

• the wall 16 does not extend over the entire length of the adapter element 2; their front and rear ends are each, as shown in Fig. 3, formed by an elastically deflectable latching hook 20, which, when the adapter element 2 is pressed from above onto the guide rail 9 of the profile 8, in contact with the horizontal leg 13 of the stop 12 is elastically deflected until it finally passes through the legs 13 and into one of the legs 13, 14 limited undercut 21 of the stop 12 engages. If such a lock is made at both ends of the adapter element 2, this is fixed and anchored immovably to the guide rail 9 except for a possible slight play in its longitudinal direction.

• the stops 12 at both ends of the primary guide rails 9 are mirror images of each other, and accordingly also the adapter element 2 has a mirror symmetry with respect to a plane perpendicular to its longitudinal direction.
• the adapter element 2 while maintaining its orientation shown in Fig. 1 on the left side profile 7 to mount, is not possible, since in this orientation no recess on the adapter element 2 is present, which could accommodate the stop 12.

Provide it is still useful, on the one hand, because then the pull-out boxes 22, 23 may be identical, on the other, because then, even if the pull-out boxes 22, 23 are not identical and, for example, differ in their dimensions, both pull-out boxes their places can and yet each one of its grooves 30 on the guide rails 9, 18 can attack.
