EP3191779B1 - Refrigeration appliance comprising a drawer - Google Patents

Description

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.

In the non-prepublished patent application DE 10 2013 203 722.8 is a refrigeration device described in which a drawer of the storage chamber in two different, laterally staggered positions can be mounted. This offers the possibility to place the drawer each adjacent to that side wall of the storage chamber which faces the axis of a door closing the storage chamber, so that despite limited pivoting freedom of the door an abutment of the drawer to a seal or other on an inside of the door protruding internals can be avoided when pulling out the pull-out box.

From the DE 10 2009 013 590 A1 is a telescopic rail system known. Furthermore, the EP 0 498 485 A2 a cooling device with containers which are arranged extendable in a cooling space of the refrigerator.

In addition, the reveals DE 10 2013 203 723 A1 a refrigeration device with a removable storage container. The refrigeration device has a mounting plate, which has webs at the opposite side edges in the width direction, which are oriented in the depth direction. In addition, the refrigeration device has a separate spacer to the plate, which is placed from above on the plate, this being done so that the spacer receives the web of the plate. An extension box is arranged in the width direction laterally to the spacer and abuts with a side wall to a side wall of the spacer.

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. If such an adapter element is attached to that guide rail which extends adjacent to the side wall to which the door of the refrigerator is suspended, then in this way can be easily created a guide for a drawer, these far enough from the door carrying side wall of the storage chamber leads away to avoid that the pull-out box abuts when pulling out of a projection of the door or it gets stuck.

Preferably, 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 also includes at least one drawer, which is guided on at least one of the guide rails, primary or secondary, movable in the depth direction of the storage chamber.

At least each primary guide rail, preferably also the secondary guide rail, is associated with a stop which restricts the freedom of movement of an extension box guided on this guide rail in the depth direction of the storage chamber, in order to prevent the pull-out box from being accidentally completely pulled 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.

Although 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 is expedient to use it, if necessary, to lock the adapter element , By being attached to two stops at both ends of a guide rail, it is strong and largely secure against overstressing by bending.

When two walls of the adapter member define a groove in which one of the primary guide rails engages, 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.

In order to enable a simple latching and releasing of the adapter element without the use of tools, 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 installed 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 drawer.

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.

Nevertheless, 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 optionally 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.

Such 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.

In order that such a frame does not hinder the mobility of the pull-out boxes, even if it rises above a top edge of the panel, 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.

Fig. 8

one too Fig. 3 analogous detail according to a further developed embodiment.

Fig. 1 shows a perspective view of a shelf 1 for a refrigerator and an intended for mounting to the shelf 1 adapter element 2. The shelf 1 comprises a flat plate 3, preferably made of safety glass, which is bordered along its four edges in a frame 4. The frame comprises a front profile 5, a rear profile 6 and side profiles 7, 8, integrally formed integrally with one another integrally formed on the plate 3 or separately prefabricated and can be attached to the plate 3 and connected to each other.

The side profiles 7, 8 are mirror images of each other. They are wider than the front and rear profiles 5, 6 and each carry at their top a guide rail 9, hereinafter referred to as the primary guide rail, in the form of a rib extending in the depth direction of the shelf 1 over a large part of the length of the profiles 7, 8 extends. As can be seen from the primary guide rail 9 of the left lateral profile 7, the primary guide rails 9 each have a flat inner side 10 facing the plate 3 and at the front and rear ends of their outer side 11 facing away from the plate 3 there is a respective hook-shaped projection to the side Stop 12 formed.

Fig. 3 shows such a stop 12 in an enlarged side view; it comprises a parallel to the top of the lateral profile 7 or 8 extending horizontal leg 13 and a vertical leg 14 which is related to the top with the horizontal leg 13, laterally with the primary guide rail 9 and down with the profile 7 or 8.

The adapter element 2 has the shape of a bar, which is slightly longer than the primary guide rail 9. As in particular in the sectional view of Fig. 4 to recognize the plastic one-piece injection-molded adapter element 2 comprises three mutually parallel, substantially vertical walls 16, 17, 18, wherein the walls 16, 17 along their upper edges are interconnected to form a downwardly open, in the assembled state, the primary guide rail 9 receiving groove 15, and the walls 17, 18 interconnected at their lower edges, so that with the primary guide rail 9 at least in its upper region cross-sectional wall 18 can serve as a secondary guide rail 19 for guiding a resting on the shelf 1 extension box instead of the covered by the adapter element 2 primary guide rail 9.

The wall 16 does not extend over the entire length of the adapter element 2; their front and back ends are each, as in Fig. 3 shown, 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, is elastically deflected in contact with the horizontal leg 13 of the stopper 12 until it finally passes through the leg 13 and in one of the legs 13, 14 limited undercut 21 of the stopper 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.

If one expects that a user of the refrigerator will remove the guide rail 9 more often and reinstall, one can choose the elasticity of the latching hook 20 so large that a release of the adapter element 2 of the primary guide rail 9 by vigorous pulling the adapter element 2 upwards is possible. Assuming that over the life of the refrigerator away the adapter element 2 at its in Fig. 2 shown position will remain on the profile 8, the latching hook 20 may be made stiffer, so that a simple removal of the adapter element 2 of the guide rail 9 upwards is no longer possible. In such a case, a user for releasing the adapter element 2, for example, a screwdriver in the undercut 21 at both ends of the adapter element 2 introduce so that, supported on the vertical leg 14, the latching hooks 20 to urge so far back that he the horizontal leg 13 can happen again.

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.

This results in the possibility of the same adapter element 2 optional, as in Fig. 1 and 2 shown to be mounted on the right side profile 8 or attached to the left side profile 7, rotated 180 ° about a vertical axis. The adapter element 2 while maintaining its in Fig. 1 It is not possible to mount the orientation shown on the left-hand side profile 7 since, in this orientation, there is no recess on the adapter element 2 which could receive the stop 12. Thus, in any orientation in which the adapter element 2 is mountable to the profiles 7, 8, the secondary guide rail 19 formed by the wall 18 is displaced against the primary guide rail 9 carrying the adapter element 2 to the remaining primary guide rail 9 of the opposite lateral profile.

The FIGS. 5 and 6 each show an arrangement consisting of the shelf 1, the mounted on the right side profile 8 of the shelf 1 adapter element 2 and two pull-out boxes 22, 23 existing arrangement in a perspective view and in front view. The pull-out boxes 22, 23 are each substantially flat cuboid with open top, a handle recess 24 having a front wall 25, side walls 26, a rear wall 27 and a bottom plate 28 (see Fig. 7 ), in the Fig. 5 completely hidden behind the walls 25, 26 and of which in the front view of the Fig. 6 only two runners are to be seen, the undersides each form a plate 3 contacting the contact surface 29 of the pull-out box.

Along the lower edges of the side walls 26 each downwardly open grooves 30 are formed. In the groove 30 on the left side of the pull-out box 22 engages the primary guide rail 9 of the left side profile 7 a. The groove 30 on the right side wall of the pull-out box 23 surrounds the secondary guide rail 19. The grooves 30 on the mutually facing side walls 26 of the two pull-out boxes 22, 23 are in the configuration shown functionless. 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.

The grooves 30 each extend only over part of the length of the guide rails 9, 19; in the in Fig. 5 shown configuration are the pull-out boxes 22 in one rear stop position in which the rear end of a groove 30 on the right side wall 26 of the pull-out box 23 limiting leg 31 a the walls 17, 18 of the adapter element 2 at their rear ends connecting transverse wall 32 (s. Fig. 4 ) or a leg 31 on the left side wall 26 of the pull-out box 22 touches the rear stop 12 of the primary guide rail 9 of the side profile 7.

In the view of Fig. 7 the left drawer 22 is still in this rear stop position; the right pull-out box 23 has advanced to a front stop position in which a front end of its leg 31 abuts against a transverse wall 32 at the front end of the adapter element 2.

Since the skids extend only over a rear part of the bottom plate 28 and the rest of the bottom plate 28 is higher than an upper edge of the front profile 5, the pull-out boxes 22, 23 can be pulled forward without having to raise them to overcome the front profile 5 , Before or just when the runners with the contact surfaces 29 abut against the front profile 5, reach the Auszugkästen 22, 23 a front stop position, which in the case of the Auszugkastens 22 by contact of its left leg 31 with the front stop 12 of the left profile 7, in the case of the pull-out box 23 is defined by contact of the right leg 31 with the front transverse wall 32.

The adapter element 2 guides the drawer 23 parallel to a right side wall 33 of the refrigerator housing at a distance b (see Fig. 6 ), which is greater than the distance a between the left drawer 22 and the adjacent left side wall 34. Due to this asymmetry, the drawer 23 as in Fig. 7 shown without being attached to a seal 35 of a door 36 of the refrigerator or a refrigerated goods projecting from the inside of the door 36, even if the door 36, as in Fig. 7 shown, is pivoted against its closed position by no more than 20 °.

Fig. 8 shows a detail of the adapter element 2 according to a further developed embodiment. The cross section of the adapter element 2 is the same as in FIG Fig. 4 shown. At the front end of the wall 16, a circular opening 38 is formed, so that in front of the edge of the wall 16, an arc 37 extends, at its upper and lower End with the wall 16 in one piece. The wall thickness of the arc 37 is chosen low enough to allow an elastic yielding of the sheet 37 when the adapter element 2 is pressed from above onto one of the primary guide rails 9 and the stop 12 of the guide rail 9 between the arc 37 and a rigid with the (in Fig. 8 behind the guide rail 9 hidden) wall 17 connected front end wall 39 of the adapter element 2 engages.

In the in Fig. 8 shown latched position engages the horizontal leg 13 of the stopper 12 in an undercut 41 above a front apex 40 of the sheet 37 a. In contrast to the case of Fig. 3 There is no horizontal surface on which the horizontal leg 13 gets stuck when the adapter element 2 is pulled up to release it from the guide rail 9 again. The arc 37 is where it touches the leg 13, steep enough to be deflected backwards and so release the adapter element 2 again.
