In FIGS. 1 to 3 a refrigerator and / or freezer according to a first embodiment is shown. Show Fig. 1a and 1b is a perspective view into the cooling and / or freezing space of the refrigerator and / or freezer according to the invention according to the first embodiment. The arrangement of the pull-out rail is in Figures 2 and 3 each shown in sectional views.
Refrigerator and / or freezer has a device inner wall 1, which forms the cooling and / or freezer compartment. Furthermore, a device outer wall 2 is shown, which is connected to the device inner wall in a connection region. Between the device outer wall 2 and the device inner wall 1, an insulating layer is arranged, which is produced by foaming the area between the device outer wall 2 and the device inner wall 1.
On the left side wall of the device inner wall 1 shown a pull-out rail 3 is mounted, via which a drawer or a shelf can be mounted extendable. The pull-out rail has a damping and / or a self-closing 7.
According to the invention a recess 6 is provided in the device inner wall 1, in which a self-closing and / or a damping 7 of the drawer rail 3 is mounted sunk.
The pull-out rail 3 is mounted in the first embodiment via a mounting rail 4 on the side wall of the device inner wall 1. The mounting rail 4 is mounted in the region of the recess 6 on the device inner wall 1. Furthermore, the mounting rail 4 has a further recess 16, in which the self-closing and / or the damping of the drawer rail 3 is mounted sunk. The recess 16 is covered by a cover plate 5. By the recess 6 according to the invention in the device inner wall of the self-closing and / or the damping of the drawer rail 3 can be completely recessed mounted in the device inner wall. This is done by the self-closing and / or damping is mounted sunk in the recess 16 in the mounting rail, the recess 16 is mounted in the mounting rail in turn recessed in the recess 6 in the device inner wall 1.

This arrangement is in Figures 2 and 3 each shown in sectional views. The pull-out rail is designed in the embodiment as a telescopic extension with a storage pull 12 and a Montagezug 14. These are connected via another train 13. In this case, a drawer 10 is located on a projection 11 on the Ablagezug 12, while the drawer rail is mounted on the Montagezug 14 on the device inner wall. In this case, a damper and / or a self-closing 7 are provided which are in communication with the pull-out rail 3. The damper and / or self-closing is arranged next to the Montagezug 14 in the recess 6.

The damper dampens the movement of the pull-out rail in the end area of the insertion. The self-closing mechanism ensures that the pull-out rail retracts automatically to its zero position in the end area of the movement. The self-closing has, for example, a spring, which is stretched when pulling out the pull-out rail and provides for the insertion of the pull-out rail for automatic self-closing.

The mounting rail 4 is according to the invention via the mounting rail 4. The mounting rail 4 has a recess 16 in which the self-extract and / or the damping 7 are mounted completely sunk. The recess 16 is covered by the cover 5. The mounting rail 4 is mounted in the recess 6 according to the invention in the side wall of the device inner wall. As a result, there is the recess 16 of the mounting rail 4 within the recess 6 of the device inner wall.

The assembly of the mounting rail 4 takes place in that it is inserted into the recess 6 on the device inner wall and fixed by a clip connection 8. The recess 6 has for this purpose corresponding clip connection elements which cooperate with clip elements on the mounting rail 4. Then the mounting rail 4 is foamed on the device inner wall. For this purpose, foam openings 17 are provided at the back of the recess 6, through which during the foaming of the device side wall also the area 9 between the Well 6 of the device inner wall and the back of the mounting rail 4 is filled with foam. The mounting rail 4 in this case has a rear ribbing 18, which is foamed during the foaming process. As a result, an even firmer connection with the device inner wall is possible.

As in particular from FIG. 3 shows, the recesses 6 and 16 extend in the extension direction along the device inner wall. The recess 6 extends substantially over the entire length of the mounting rail 4 and the drawer rail 3. As a result, the mounting rail can be foamed on its entire back with the recess 6. The recess 16 for receiving the self-closing or the damping 7, however, extends only over a portion of the extension of the mounting rail in the extension direction, so that space for the mounting portions 15 remains. The depression 16 is arranged between two attachment regions 15 for fastening the pull-out rail 3. In these attachment areas 15, the pull-out rail is connected to the mounting rail 4, z. B. by a screw or a latch.

In FIGS. 4 and 5 a second embodiment of the present invention is shown, in which the pull-out rail 3 is mounted directly on the device inner wall 1. The pull-out rail 3 in this case has a storage draw 31, on which a storage shelf 30 is arranged. The filing train 31 is mounted on a Montagezug 32 via a ball bearing rail. The mounting pull 32 of the pull-out rail is mounted in the second embodiment between two projections 33 on the side wall of the device inner wall 1. The projections in this case form a receptacle for the pull-out rail. 3

In the middle and rear area, the drawer rail 3 or its Montagezug 32 is thereby sunk. Front side of the Montagezug 32, however, aligned with the front side wall portion 34, so that the Ablagezug 31 here from the Montagezug 32 is extendable.

The pull-out rail 3 has a damped self-closing 7. This is inventively arranged in a recess 6 of the device inner wall. The recess 6 is inserted between a front and a rear mounting region for the drawer rail 3 in the side wall of the device inner wall. In the extension direction, a mounting region of the device inner wall is therefore initially provided in the region of the pull-out rail 3, which is aligned with the front side wall region 34. At this mounting area then joins the recess 6. The recess 6 is adjoined in turn by a mounting region, which is in alignment with the first mounting region and the front inner wall region 34.

In the second embodiment, the drawer rail 3 is attached directly to the device inner wall 1, without a mounting rail would be provided. Furthermore, the self-closing or damping 7 is located directly inside the recess 6 of the device inner wall. The recess 6 in the device inner wall 1 in this case has only an opening to the device interior in the embodiment, is opposite to the insulating layer 20, however, closed. The area between the walls of the recess 6 and the damping or the self-closing 7 is thus not foamed.

The recess according to the invention in the device inner wall makes it possible not to place the damper with the self-closing between the side wall and the drawer or the shelf, but completely or mostly in the recess in the side wall of the refrigerator and / or freezer. An advantage of the installation according to the invention is that the useful content is not or not significantly reduced. In particular, a drawer or a storage shelf, which can be pulled out via the pull-out rail, does not have to be reduced in size, as was still necessary in the state of the art in order to create sufficient space for the damper or the self-closing mechanism. Rather, the damper or self-closing can be arranged to save space in the recess in the side wall. Furthermore, it is advantageous that by installing in the side wall recess of the damper and the self-closing completely or largely blinded without disturbing structure can be, so that after removal of drawer or shelf cleaning mostly largely without interference edges in this area is possible. The installation in the recess in the side wall is particularly advantageous for transparent or translucent drawers or shelves in order to provide an improved visual impression. It is also advantageous that existing drawers or shelves by the recessed installation of the damper or self-closing constructive not or not significantly changed and these installations do not collide with food.

The recess in the side wall is ideally located between two areas for Auszugsschienenbefestigung. However, a depression above or below the pull-out rail or pull-out rail attachment or behind a pull-out rail mounting area is also conceivable.

As described, the drawer can be fastened to the sidewall attachment by means of a fastening rail, whereby the fastening rail is foamed with the sidewall. The mounting rail is advantageously designed as an injection molded part. In this case, the mounting rail advantageously between two areas for Auszugsschienenbefestigung a recess and thus the required installation space for the damping and the self-closing. Alternatively, an installation above, below or behind a mounting area would be possible by a corresponding structure of the mounting rail and a corresponding arrangement of the recess of a mounting rail.

The executed as an injection molded mounting rail for fastening the pull-out rail can be engaged in the recess on the side wall before the foaming and held by the foam pressure at this without screwing. Through the foam opening in the region of the depression in the device inner wall, it is possible auszuschäumen the back ribbing of the mounting rail. This has the advantage that the mounting rail is even better connected to the side wall of the household appliance and a better insulation is achieved by the additional foam. The mounting rail has this advantageously on their Rear side of a ribbing, which is foamed. The foaming of the side wall and the area between the recess and the back of the mounting rail takes place in one operation, with a foam outlet can be avoided without additional sealing measures.

Since different loads and requirement profiles depending on the drawer size and the allowable load different requirements for the damping and Selbsteinzugskraft, a corresponding adjustment can be made by the installation of different extension rails. A drawer or a shelf is usually mounted by two pull-out rails right and left on the inner walls of the household appliance, in particular refrigerator and / or freezer. Both pull-out rails can be provided with a damper and a self-closing mechanism. Alternatively, only one pull-out rail can be provided with a self-closing mechanism and a damper, while the other pull-out rail eliminates the damper and the self-closing mechanism. Depending on requirements, however, a damper and a self-closing can also be provided on a pull-out rail, on the other pull-out rail, however, only a damper or only a self-closing.

Advantageously, the invention provides that the extract with damper and / or self-closing including fasteners approved for food and / or consists of odorless materials.

Furthermore, a drawer, as shown in the first embodiment, be mounted directly on the pull-out rails. Alternatively, it is also possible, as shown in the second embodiment, to first mount a carrier plate on the pull-out rails. On this support plate can then be arranged as needed, a drawer or other container. However, a carrier plate mounted on the pull-out slide can also be used without a drawer as pull-out shelf. The support plate may for example consist of glass or plastic.

According to the invention, a cost-effective and space-saving installation of pull-out systems with self-closing and / or damping is provided by the recess in the device inner wall, which also has considerable advantages in terms of optical and hygienic aspects. In this case, the self-closing or the damper of a pull-out rail can be partially or completely mounted in the recess according to the invention in the device inner wall. According to the invention, however, the installation of a pull-out system without self-closing but with damping or a pull-out system without self-closing and without damping on the same device inner wall is possible. In particular, the installation is carried out on a mounting rail, which is foamed into the recess on the device wall. Alternatively, however, the assembly can also be done directly on the device inner wall.

Furthermore, it is conceivable to mount a damper and / or a self-closing mechanism on a telescopic rail system which is mounted on a carrier plate. A mounted on a support plate telescopic rail system is in the WO 2006/048307 A1 the contents of which are incorporated herein by reference in their entirety. At the telescopic rails shown there, which z. B. are mounted on a glass plate, a damper and / or a self-closing can now be attached.

It is also conceivable steamer and / or self-closing in synchronized telescopic rail systems, in which the left and the right telescopic extension are connected, for. B. via a connecting rod with z. B. gear and rack on the telescopic rail to use. In certain arrangements, a central installation of damper with self-closing is conceivable.

In FIG. 6 a third embodiment of a household appliance according to the invention is shown, in which a pull-out rail 42 is sunk in a recess 41 of the side wall 40 of the household appliance sunk. The pull-out rail 42 is seen completely sunk in the recess 41 in the width direction of the household appliance. The recess 41 can by a deep-drawn area be formed of the inner container of the household appliance. In this case, the recess 41 may also be designed as a separate element which is attached to a recess of the inner container, as has been shown in the first embodiment.

Furthermore, a Selbsteinzug 43 is provided in the embodiment, which can be designed with or without damping. Instead of the self-feeder, only one damping can be provided. Also, the self-closing 43 and the damping are sunk in the depression. In the third embodiment, the entire extraction mechanism is hidden in the inner container wall. Due to this construction, a much larger storage space is possible. However, the recess 41 must be open in the extension direction towards the front in order not to prevent the pull-out rail 42 from retracting.

The recess 41 is covered by a protective cover 46, which prevents soiling and avoids a direct view of the extract and the self-closing, whereby an attractive appearance is achieved. By the embodiment according to the invention damage to the extension mechanism can be prevented because the self-closing or the damper can not be reached by the user. The pull-out rail 42 can only be reached outside the refrigerator in the extended state.

In this case, both the extract and the self-closing or damping are mounted on a recess 41 comprehensive element forming a holding piece. For countersunk mounting the retaining piece is embedded in the inner container wall 40.

The drawer 44 has a support 45, which establishes a connection with the pull-out rail 42 and which is so wide that it protrudes into the recess 41. Advantageously, the self-closing 43 or damper is directly connected to an extract element of the pull-out rail 42 in operative connection. For mounting the drawer 44 so that only the support 45 must be mounted on the pull-out rail 42.

Another advantage of in Fig. 6 The solution shown is the compact design. All components for the functions that serve to extend and insert the pusher are attached to the support piece. This allows a separate installation of this unit, the functional test of the unit before mounting in the device and easy handling when installed in the device. In particular, the recess 41 may be designed as a mounting rail, which is mounted on the container inner wall.

Advantageously, recessed mounted extension rails 42 are provided on both sides of the thrust element, as these in Fig. 6 shown only for the one side. As already stated above, a self-closing mechanism 43 or a damper does not have to be provided on both sides.

In the embodiments shown so far, the self-closing mechanism or the damper forms part of the pull-out rail arrangement or acts directly on the movement of the pull-out rail. The self-closing or damping thus acts only indirectly via the pull-out rail on the movement of the push element.

However, the present invention is not limited to such embodiments. Rather, the damping or self-closing can also form a separate element which does not act on the pull-out rail, but via a driver on the movement of the push element. In this case, the damping or the self-closing can be arranged in a first variant on the thrust element, while the driver is arranged on a stationary element of the household appliance. In a further variant, however, the driver is arranged on the drawer, while the damping or self-closing is arranged on a stationary element of the household appliance.

In FIGS. 7 to 9 In this case, pushing elements according to the first variant are shown, in which a self-closing or damper 51, 61 is integrated in the push element 50, 60. In this case, a depression is provided on the pusher, in which the self-closing or the damping is mounted sunk. Again, a self-closing with or without damping or even a damping can be used.

At the in FIGS. 7 to 9 shown embodiments of the present invention, the self-closing or damping is housed in a drawer. Other pushers such as Abstell are but also conceivable.

The self-retraction 51, 61 or the damping lies in a pocket in the rear region of the push element 50. The pocket thus forms a depression, in which the self-closing mechanism or the damping is mounted countersunk. The entire self-closing mechanism or damper is thus back and thus protected against damage. By a translucent version of this area, for example, the self-closing mechanism or damper can be hidden.

The installation of the self-closing or damper can be done for example by means of latching hooks, so that the self-closing or damper can be easily inserted into the recess and there engages in its end position. Disassembly can then be done advantageously only by customer service with a tool.

The positioning of the self-closing or damper can be done left, right or center. The positioning in the middle, as in Fig. 7 is shown, offers the advantage that the introduction of force takes place centrally. The drawer runs evenly and straight, tilting is prevented, especially at full load.

Alternatively, however, an arrangement of Selbsteinzugs as in Fig. 8 left and / or right on the pusher 60 conceivable. The self-feeder 61 or the Damping can be arranged, for example, in an edge region of the drawer below the pull-out rail 62.

In this case, a driver element 62 is provided, which engages in the self-closing 61 or damper, when using a feeder 61 starts this. The driver element engages in the self-closing or damper and absorbs the tensile or compressive forces. The driver element detents advantageously when pulling out of the self-closing or damper and thus allows in the remaining area of the drawer a free extension movement.

The driver element 62 is arranged on a corresponding fixed area of the household appliance. The entrainment element forms when using a self-closing the activator for this self-closing. If, on the other hand, only one damper is used, the driver element can also be a simple stop element.

The driver element can be formed as an integral element of another component, for example as a raised hook on a lid. However, the driver element may also be designed as a separate component, for example as a carrier part with latching hook, which is introduced into the bottom of the inner container.

Advantageously, while the driver element on the household appliance forms a projection which engages in a recess on the self-closing or damper and so transmits the forces from the movable part of the self-closing or damper on the thrust element.

The self-closing mechanism offers greater comfort to the customer, and the drawer runs smoothly and quietly after the self-closing mechanism engages.

As in FIGS. 7 to 9 shown, the self-closing can be arranged in the bottom region of the thrust element. The driver element 62 is then to a corresponding fixed area of the household appliance, ie below the drawer, for example, an intermediate floor, a cover or the bottom of the inner container.

The self-closing or damping is advantageously so sunk in the bottom region of the thrust element that the thrust element can be easily parked after removal from the home appliance on a flat surface. Advantageously, the surface of the thrust element in the region of the damping or self-closing forms a flat surface without interfering edges.

Retrofitting a household appliance with a self-closing or damper is possible at any time for example by the exchange of the push element or the impressions of the self-closing or damper in a franking of a pusher. If the driver element is attached to a replaceable component, then it can be replaced. However, such a driver element can also be attached from the outset to the corresponding component. Alternatively, the driver element may be designed as a separate component, which is attached for retrofitting to a stationary component of the household appliance.

While in Fig. 8 the self-closing or the damper is arranged below the pull-out rail 62, an arrangement is also possible above the pull-out rail 62, for example in the side wall of the drawer. The driver element must then be arranged accordingly on the lateral inner wall of the inner container.

In Fig. 10 Now an embodiment is shown in which on the pusher element 70 only a first driver element 72 is arranged, while the self-feeder 71 or damper is arranged on a fixed portion of the household appliance, in this case on an intermediate bottom 73. Alternatively, the self-feeder 71 and Damper also be arranged on a lid or part of the inner container. To install the self-closing or damping is in turn a corresponding recess provided in which the self-closing or damping is mounted sunk.

In this case, the self-closing or the damper is firmly housed in a lying under the pusher 70 bottom, lid or inner container. He lies in a bag in the back area. The entire self-closing is back and is thus protected from damage.

Only a second driver element 74 looks out of the self-closing mechanism or damper and can engage with the first driver element 72 on the push element 70.

The self-closing or damping can in turn be mounted by means of latching hooks, so that the self-closing mechanism or damper can be simply inserted and locks in its end position in the recess. Disassembly can then only be done by customer service with a tool.

The positioning of the self-closing or damper can in turn be left, right or center. The positioning of the center offers the advantage that the force is applied centrally. The drawer runs smoothly and evenly so that tilting is prevented, especially at full load.

The technical implementation of a self-closing requires the first driver element on the push element, which engages in the self-closing, starts the self-closing and absorbs the tensile forces. The first cam member 72 on the pusher is sunk thereon. By lying back of this driver element damage during storage of the drawer, for example, in the kitchen when removing and cleaning can be avoided.

Retrofitting an existing household appliance with this embodiment of the present invention can be done by replacing a lid or shelf with such self-closing or damper. alternative can also be arranged a self-closing or damper in a receptacle of the inner container.

The entrainment element on the drawer can be mounted there or made available by an exchange of the push element. The driver 72 on the pusher engages again in the self-closing and absorbs the tensile forces. He snaps while pulling out. The driver is concealed in the pusher arranged to prevent damage.

The past installation of the self-closing or damper according to the present invention results in an extremely compact and interference-proof construction. In particular, a cover may be provided which covers the depression and the elements arranged therein. As a result, damage can be excluded that the self-closing or damper can not be reached by the user.

However, this must be a force transmission from a movable element of the self-closing or damper over a certain thrust path away on the push element. In this case, for example, a rubber lip along a slot may be provided, through which passes a driver, which produces the non-positive connection between the movable part of the self-closing or damper and the pusher.

Alternatively, the cover can also run over the necessary thrust path with movable element of the self-closing or damper. Advantageously, the cover is therefore guided displaceably on the recess. As a result, a slot can be avoided and the depression completely encapsulated. The power transmission then takes place via a second driver element on the cover.

Further advantageously, the self-closing or damper is arranged in a recess of a mounting rail, which in turn in a recess of the inner container is arranged. By lying on the mounting rail, which in turn is located in the inner container, the self-closing or damper takes no storage space to complete.
