Description

Refrigerating appliance, in particular household refrigerating appliance with a

Towing Fittings

The invention relates to a refrigeration appliance, in particular household refrigerating appliance, comprising a body with a coolable interior space and a door leaf provided for opening and closing the interior space, which is articulated to the body by means of at least one hinge during pivoting.

From US 3,722,031 a refrigeration device is known, which has a door which is hinged by means of hinges pivotally mounted on a carcass. One of the hinges has a bearing bush connected to the door and a bushing connected to the body. Each bushing has alternating lugs and chamfers extending in radial directions. The lugs and chamfers define start-up inclined surfaces, which cause an automatic closing movement of the door by the action of gravity on the door.

DE 73 34 526 U1 describes a refrigerator door which is provided with driver elements which are guided on guide elements, in particular rails, of an outer, upstream furniture door. The refrigerator door is connected to joint parts which cooperate with corresponding guide elements of the outer furniture door and ensure a mutual movement of the two doors. For this purpose, a driver arm is articulated on the upper side of the door, which is rotatably mounted in a journal bearing and is slidably guided with its other end in a profile rail.

The object of the invention is to provide a refrigerator, in particular household refrigeration appliance with an improved tow-door fitting.

The object is achieved by a refrigerator, in particular household refrigeration appliance, comprising a body with a coolable interior and a door opening provided for opening and closing the door leaf, which is hinged to the body by means of at least one hinge during pivoting, and further comprising a connected to the door leaf and connectable to a furniture door tow-door fitting, which is designed to pivot a movement of Mö- belt door and door leaf and the compensating means, which are adapted to follow a change in the height position of the door leaf during pivoting.

According to the invention, it is therefore provided that the tow-door fitting connects the door leaf and the furniture door in such a way that pivoting of the furniture door is transmitted to the door leaf, but a movement of the door leaf during pivoting in the vertical direction is not transmitted to the furniture door. The compensating means serves not to transmit a movement of the door leaf occurring during pivoting in the vertical direction to the furniture door. The compensating means can in principle be designed differently, for example by an elastic intermediate member or by an intermediate joint between the furniture door and the door leaf.

In one embodiment, the tow door fitting may have a door part attached to the fitting part and a furniture door side fixed fitting part, wherein these two fitting parts are connected via the compensating means. The door leaf side attached fitting part couples so far the compensating means to the door leaf and the furniture door side fixed fitting part couples so far the compensating means to the furniture door.

In a further development, the tow-door fitting may have a door part attached to the fitting part and a furniture door side fixed fitting part, wherein the compensation means may be arranged between these two fitting parts. The door leaf side attached fitting part couples so far the compensating means to the door leaf and the furniture door side fixed fitting part couples so far the compensating means to the furniture door.

The compensation means may in particular comprise a guide rail and a cam running in the guide rail, which is guided along a movement path adapted to the height-adjustable door leaf. While the door leaf is being swiveled, the driver describes a trajectory in the room. The movement path in the room gives a trajectory with respect to a plane between the door leaf and the furniture door. The trajectory has a horizontal trajectory component due to the height-movably hinged door leaf. The trajectory of the driver returns the shape or the shape of the guideway of a guide rail again, which with a door leaf side fitting part or a furniture door side fitting part can be connected.

By the guide rail and the driver a compensating means is provided which manages without elastic intermediate links or without kinematically complex intermediate joints. This creates a reliable and cost-effective compensation means.

The guide rail may be configured to follow the driver. In this case, the guide rail, for example, be movably or articulated mounted on the door leaf or the furniture door and the guide rail follow the driver that, depending on the altitude of the driver or the door leaf, the guide rail pivots about a horizontal axis of rotation or in vertical Direction translationally moved.

In a further embodiment, the guide rail can be connected to the fitting part fastened on the door leaf side and the catch can be connected to the fitting part fastened to the furniture door side, and the guide rail can be designed to extend in accordance with the movement path of the driver. The guide rail is therefore not straight, but has, for example, a curved course to follow the path of the driver. The curved course has movement direction components which are in a vertical direction. go up or down. Alternatively, the guide rail may be connected to the furniture door side mounted fitting part and the driver with the door leaf side mounted fitting part and the guide rail of the path of movement of the driver be designed to extend accordingly. Again, the guide rail is not straight, but for example, has a curved course to follow the path of the driver. The curved path also includes motion direction components that are in a vertical direction, i.e., in a vertical direction. go up or down.

In all embodiments, the guide rail may be formed correspondingly curved in the course of the movement path of the driver. The curved running ing rail can have a vertical direction component in at least one section.

In principle, the compensating means may be adapted to the respective height position of the door leaf or the driver corresponding to the height offset between the door leaf and the furniture door, which adjusts during the opening or closing of the door leaf as a function of its opening angle position. In a specific embodiment, the movement path can be adapted to the respective height position of the door leaf or the driver corresponding to the height offset between the door leaf and the furniture door, which adjusts during the opening or closing of the door leaf as a function of its opening angle position. Thus, for example, in the embodiment with a guide rail and a driver, the guide rail have a course that is congruent with a development of an axial cam track, for example a self-closing under gravity hinge in which an axial cam during pivoting of the door leaf runs along the axial cam and thereby the Door leaf raises and lowers. In general, in all versions, the hinge may be a self-closing hinge under gravity.

The hinge may have a first hinge part with at least one axial cam and a second hinge part with at least one axial cam track whose path development is congruent to a guide track of the tow door fitting. In summary, and in other words, the invention provides a tow-door fitting, with which in particular built-in refrigerator, which are provided with a furniture door, can also have a self-closing effect. An inventive refrigeration device can to a door hinge having a flow curve, which raises the door when opening, for example, due to gravity when closing the door on the flow curve, a door closing force is generated. To solve the problem with a built-in refrigerator that the door, ie the door leaf of the refrigerator performs a vertical movement, the furniture door, however, is vertically fixed, the invention proposes a tow-door fitting, which connects the furniture front and the door via a horizontal slide, wherein to avoid a clamping Compensation means is provided, which may be formed, for example, as an oblique and / or curved rail.

An exemplary embodiment of the invention is described with reference to the figures 1 to 4. From the detailed description of this specific embodiment, there are also other general features and advantages of the present invention.

4 is a perspective view of a vertically movable hinge according to an embodiment of the invention; 5 shows a side view of the vertically movable hinge according to FIG. 4.

A shown in Fig. 1 household refrigerator 20 is designed as a built-in device. The domestic refrigerator 20 has a body 21 which defines a coolable interior 22. The coolable interior 22 is accessible via a door leaf 6. The door leaf 6 is provided for opening and closing the inner space 22 and is hinged in the embodiment shown by means of hinges 1 on the body 21. At least one of the hinges 1 is articulated so that it can move vertically, ie during a pivoting of the door leaf 6, the door leaf 6 raises or lowers slightly. On an outer side 24 of a door panel 6, a furniture door 7 is coupled. In Fig. 2, the door panel 6 and the furniture door 7 is exploded in isolation. The door leaf 6 is connected to the furniture door 7 via an upper and lower tow-door fitting 26 in the exemplary embodiment. The tow-door fitting 26 couples a pivoting movement of furniture door 7 and door leaf 6. To open a user of the household refrigeration appliance 20, the furniture door 7 swing open, due to the tow-door fitting 26, the door leaf 6 of the household refrigerator 20 is pivoted and the interior 22 to Insertion or removal of refrigerated goods is accessible. In addition, the furniture door 7 actuated due to the tow-door fitting 26 actuated by an automatically closing door leaf 6 also be closed automatically. In other words, the automatically closing door leaf pulls the furniture door 7 into a closed position. The tow-door fitting 26 can, as in the illustrated embodiment according to FIG. 2 have at least one guide rail 13 in which a driver 12 is guided. In the embodiment according to FIG. 2, the guide rail 13 is connected to a fitting part 13a attached to the furniture door side and the driver 12 is connected to a fitting part 12a fastened on the door leaf side. The guide rail 13 is a movement path 27 of the driver 12 is designed to extend accordingly. The guide rail 13 is designed so far to follow the driver 12. By means of a predetermined by the movement path 27 guideway, the guide rail 13 is formed with a compensating means which is adapted to follow a change in a height offset between the door leaf 6 and furniture door 7 during pivoting. The compensating means has in the illustrated embodiment, the guide rail 13 and the current in the guide rail 13 driver 12, which is guided along the path of movement 27 predetermined by the height-adjustable door leaf 6. The guide rail 13 is to the course of the movement path 27 of the driver 12 is formed corresponding curved.

3a to 3e illustrate by means of a sequence of snapshots a relative movement between the door leaf 6 of the built-in refrigerator and the furniture door 7 in response to an opening angle 1 1 of the two doors 6, 7 according to an embodiment of the invention. In order to achieve a better clarity of Figures 3a to 3e, a label with reference numerals has been made only on the basis of Figure 3d representative of Figures 3a, 3b, 3c and 3e, which have the same elements of Figure 3d. The door leaf 6 is coupled via the tow-door fitting 26 to the furniture door 7. Both doors 6, 7 each have their own axis of rotation. The furniture door 7 may be hinged with any conventional hinge. In this embodiment, the driver 12 may be attached to the furniture door 7, while a guide rail 13 may be attached to the built-in appliance door. This is particularly advantageous when a certain flow line of the hinge 1 is present, which is directly proportional to the guide line of the guide rail 13. Then the driver 12 can be installed by a user in a simple way in the furniture door. So that a relative movement between the two doors is possible, the towing connection, which comprises at least one driver element 12 and one guide rail 13, designed such that a guide 14 of the driver 12 is matched in the guide rail 13 with a flow line that a guide line 14th equivalent. The guide line 14 of the hinge 1 describes insofar a change in an axial stroke of the door leaf 6, or the hinge 1. In Figures 3a to 3e corresponding to the stroke of the hinge 1 trajectory 27 of the driver 12 is directly proportional to the guide line 14 and therefore , For the sake of clarity, also provided with the reference numeral of the guide line 14. In the embodiment shown by way of example two drivers 12 and two associated guide rails 13 are provided for the realization of the towing connection. The relative displacement shown in the schematic diagrams takes place only in a plane containing the two drivers 12 and guide rail 13 and not perpendicular thereto. In addition, an opening angle 1 1 of the door leaf 6 or the furniture door 7 is shown.

In Fig. 3a, the two doors 6, 7 are shown in a closed position of the door panel 6. Accordingly, the opening angle 1 1 of the doors in Fig. 3a is equal to 0 degrees. 3b shows the two doors 6, 7 at a small opening angle, for example 1 degree to 30 degrees without stroke of the hinge 1. Once the furniture door 7 is opened by a user, pulls the furniture door 7 means of the tow-door fitting 26 that is the guide rail 13 and the driver 12, the door leaf 6 with. This position occurs because of the distance from each other and parallel Swivel axes of furniture door 7 and door leaf 6 to a displacement of the furniture door 7 in the horizontal direction.

Fig. 3c shows the two doors 6, 7 at a further increasing opening angle 1 1, e.g. 31 degrees to 45 degrees. The displacement of the furniture door 7 in the horizontal direction continues continuously with increasing opening angle. From an opening angle of, for example, 31 degrees, the door leaf 6 is lifted by the hinge 1.

In the present embodiment of the invention, the guide line 14 of the guide rail 13 has a plateau. In this position, the doors 6, 7 are stopped in a rest position, for example, for insertion and / or removal of the built-in appliance.

In FIG. 3d, this position is held, for example, between an opening angle of 45 degrees to 100 degrees. In the figure 3d it is shown that the furniture door 7 shifts continuously only in the horizontal direction to the axis of rotation, but not in the vertical direction relative to the door leaf. 6

FIG. 3 e shows an embodiment, for example, in the case where an opening limiter is provided. In this case, the door leaf 6 slides together with the rotary push joint in a limiting latching position, which prevents further automatic opening but also closing the doors 6, 7. Such an embodiment may for example be provided for defrosting a built-in refrigerator, if it is necessary to keep open the door panel 6, here e.g. at an opening angle of 130 degrees. So that the doors 6, 7 close automatically, the doors 6, 7 must be pivoted so far back that the self-acting mechanism is activated again. In this embodiment, the doors 6, 7 are rotated back to an opening angle 1 1 of less than 45 degrees. Then closes the door panel 6 and tows the furniture door 7 via the driver 12 and the guide rail 13 with it.

FIG. 4 shows a perspective view of a hinge 1 embodied by way of example as a rotary push hinge, as can be used in conjunction with a tow door fitting 26 according to the invention in an automatic closing device. The illustrated hinge 1 is fixedly mounted on a device-side bearing arm 2, the in turn can be attached to the body 21 of the household refrigerator 20. The bearing arm 2 forms a hinge part so far 28. From the device side bearing arm 2 is perpendicular to a pivot pin 3 which is rotatably received by a remote bearing bushing 4. The bearing bush 4 can be connected to the door leaf 6 again by means of a door-side support arm 5. The bearing arm 5 forms in this respect a further hinge part 29. The journal 3 is shown in Fig. 4 in a rotated by about 100 degrees position, which corresponds to an approximately equal opening angle of the door panel 6. In a closed position of the door leaf 6, the two bearing arms 2, 5 in the same direction. Then they are in a locked position where the doors close.

The bearing pin 3 is peripherally surrounded at its end connected to the device-side bearing arm 2 with a collar 8 fixedly connected thereto. The collar 8 has the shape of a cylinder segment with a variable height, wherein an edge development of the collar 8 is equal to a curved line or a polygon. The surface of the collar 8 forms an axial cam track 23.

A the device-side bearing arm 2 facing edge of the bearing bush 4 is also surrounded by a collar 9 so firmly connected. The surface of the collar 9 has at least one axial cam 25. As soon as the door leaf 6 closes, the two complementary-shape collars 8 and 9 snap into one another. In other words, the axial cam 25 of the collar 9 slides on the axial cam track 23 of the collar 8. Due to the axially lifting and lowering contact surface 10 of the axial cam 25 runs at a pivoting of the door leaf 6 on the axial cam 23, wherein the door leaf 6 accordingly in an axial direction ie vertically raises or lowers.

5, the hinge 1 is shown in a deflected from the rest position position, for example, when unscrewing the door side bearing arm 5 when opening the built-in appliance door, the door-side bearing arm 5 moves together with the door leaf 6 in the axial direction of the device-side bearing arm 2 away , In this case, the complementary shapes of the two collars 8, 9 can be seen. Likewise, the contact surface 10 shown.
