EP3143227B1 - Bearing arrangement for a door - Google Patents

Description

The present invention relates to a storage arrangement for a door of a piece of furniture or household appliance, in particular for refrigerators or freezers according to the preamble of claim 1.

From the EP 2 020 477 a swing door of a piece of furniture or household appliance is known, which can be driven with a door closer or swing leaf drive. The door closer has a drive shaft which interacts with the swing door in such a way that rotation of the drive shaft causes the swing leaf to pivot. The axis of rotation of this drive shaft is identical to the axis of rotation of the swing door.

From the US 2006/038412 A1 a bearing arrangement with a bearing element for the rotatable mounting of a door and a damping element for damping a closing movement of the door is known.

From the US 2005/258724 A1 a bearing arrangement with a bearing element for the rotatable mounting of a refrigerator door and a damping element with a spring for damping or shock absorption of a closing movement of the door is known.

From the EP 2 314 962 A2 a bearing arrangement with a bearing element for the rotatable mounting of a refrigerator or freezer and a damper with a spring for damping a closing movement of the door is known.

The disadvantage of this rigid connection between the swing door and the door closer is that even a slight offset of the drive shaft from the axis of rotation of the swing door can lead to wear of the door hinges or the drive shaft of the door closer.

The resulting higher friction within the connection between the swing door and the door closer also requires higher forces to drive the swing door, so that an offset between the axes of rotation of the door closer and the swing door can sometimes mean that the door closer does not have enough force to completely close the door close.

Accordingly, the installation of the door closer on the furniture or household appliance must also be carried out extremely precisely in order to rule out such an axis shift as far as possible.

The object of the present invention is to provide a bearing arrangement for a door of a piece of furniture or household appliance, with which a simple and flexible positioning of a locking device for a door is made possible.

This object is achieved with a bearing arrangement for a door of a piece of furniture or household appliance with the features of claim 1 or with the features of claim 2.

The bearing arrangement according to the invention has a bearing element for the rotatable mounting of the door on a body of the furniture or household appliance around a bearing axis and a locking device attached to a body of the furniture or household appliance or the door in a housing, by means of which the door is driven by a drive part over a swivel range can be moved in the closing direction or opening direction, wherein a spring, in particular a compression spring, serves as the drive part, or the drive part is designed as an electrical drive part, in particular as an electric motor, the closing device, the drive part and a first rotary element receiving a rotary movement of the door around the bearing axis with a for Has the bearing axis of the door essentially parallel axis of rotation. This first rotary element is connected to the door via a compensation device for compensating for a length offset and / or angular offset between the axis of rotation of the first rotary element and the bearing axis of the door. A damper for damping a pivoting movement of the door when the door is opened and closed is received in the closing device over at least one pivoting range which is coupled to the first rotary element. The compensation device has a driver that can be coupled to the first rotary element in a rotationally fixed manner and moves the door in the closing direction and / or opening direction.

The driver insertable into a recess of the door has a bolt that can be coupled non-rotatably to the first rotary element and a driver arm that is tiltably held on the bolt in an angular range between 75 ° and 105 ° to the axis of rotation of the first rotary element.

Such a driver also makes it possible to compensate for a vertical lowering of the door.

Alternatively, the driver is designed as a non-rotatable bolt that can be received with the bearing element of the door.

In order to enable an angular offset between the axes of rotation of the door and the first rotary element in this variant as well, an end piece of the driver protruding into the first rotary element can be tilted at a predetermined angle around the axis of rotation of the first rotary element.

This makes it possible to compensate for a length offset and / or angular offset between the axis of rotation of the door and a first rotary element which absorbs the rotary movement and with which the closing device is activated to close or open the door, which has various advantages.

On the one hand, this makes it possible to compensate for tolerances and displacements, for example due to wear on the door hinges that occurs over time or a lowering of the door.

Furthermore, the bearing arrangement according to the invention enables the locking device to be attached to the body of the furniture or household appliance if the compensating device is dimensioned accordingly, without having to ensure that the axes of rotation of the door and the rotating element of the locking device correspond exactly.

Another advantage of the bearing arrangement according to the invention is that, in principle, a design of a locking device can be used on furniture or household appliances with different suspensions of the door, with only the compensation device having to be adapted to the mechanics of the door suspension.

The arrangement of the damper enables both safe closing and damping of the door when the door is opened and / or closed.

The use of the curve guide makes it possible to precisely set the forces for closing or opening or for damping, since there is no longer a rigid coupling between the door and the closing device or damper, but this coupling takes place via one or more curve guides that are activated when the door is pivoted act on the locking device and / or the damper.

The compensating device with a driver that can be coupled non-rotatably to the first rotary element and moves the door in the closing direction and / or opening direction enables the rotary movement to be transmitted from one of the rotary elements through the closing device to the door and vice versa. Such a driver enables the compensation of tolerances of the displacements or an angular offset of the bearing axis of the door with respect to the axis of rotation of the locking device.

To compensate for misalignments and angular misalignments, a tilting edge is particularly preferably used, on which the driver arm can be tilted in the aforementioned angular range.

The recess in the door is preferably dimensioned larger than an insert part of the driver in order to allow the driver to tilt, as described above. A displacement of the insert part of the driver relative to the door is also provided here in order to compensate for corresponding misalignments.

In the opposite case, a protruding part of the door, for example a bolt fixed on or in the door, can of course also be coupled to the driver, for example by protruding into an opening of the driver.

In the embodiment of the invention in which the driver is designed as a bolt that can be held in a rotationally fixed manner with the bearing element of the door, the bearing element is preferably designed as a hinge with a through-hole for the driver, the bolt being held in the door recess in a rotationally fixed manner.

The tiltability is preferably achieved by designing the end piece of the driver in the form of a spherical head. The end piece of the driver is mounted in the first rotary element in a form-fitting manner in the direction of rotation of the first rotary element, the circumferential contact surfaces of the end piece of the driver being spherical. In this way, the driver is able to maintain a non-rotatable connection to the first rotary element even in the slightly tilted state.

Other possibilities for coupling the driver to the door are also conceivable. The driver can be attached to the top / bottom of the front surface of the refrigerator door, or it can only be attached or plugged in. It also offers itself a coupling to the inner surface of the door without changing the external appearance of the furniture or household appliance.

When the compensating device is designed with a second rotary element, the above-mentioned driver is coupled to the second rotary element.

The transmission of the rotary movement of the door can be transmitted in various ways with such a second rotary element. It is thus conceivable to connect the rotating elements to one another, for example via a toothed belt.

This makes it possible to bridge larger distances between the two rotating elements, so that the locking device can be positioned further back, for example with a correspondingly long toothed belt, that is, in the direction of the rear wall of the furniture or household appliance, preferably on its upper side.

If the locking device is attached to the door in a variant not according to the invention, the transmission of the rotary movement to a second rotating element can be used to position the locking device at a location on the door where more space is available than near the bearing point to the body is available.

It is also conceivable to design the two rotary elements as gear wheels, so that the rotary movement of the door is transmitted to the locking device by the meshing of the teeth of the rotary elements designed as gear wheels.

Depending on the control of the locking device, it is also conceivable to use a third gear as an intermediate element between the first and second rotary element designed as a gear in order to keep the direction of rotation of the first and second rotary element the same.

The axis of rotation of the second rotary element is here preferably the same as the bearing axis of the door. As described above, structural deviations / tolerances can be compensated for by using an above-mentioned driver.

Since only a very small amount of space is required to transfer the rotary movement of the second rotary element, this makes it possible in a simple manner to design a housing surrounding the locking device and / or the compensating device so that it does not go over the front edge of the door of the furniture or household appliance protrudes if the locking device and the compensating device are attached on or under the body of the furniture or household appliance.

Both the locking device and the
Damper can be biased against the curve guide by a spring.

The storage arrangement according to the invention can be used in particular for furniture or household appliances, for example for refrigerators or freezers.

In the following description of the figures, terms such as above, below, left, right, front, rear etc. relate exclusively to the exemplary representation and position of the bearing arrangement, the door, the locking device, the rotating elements, the driver and the like selected in the respective figures. These terms are not to be understood as restrictive, that is to say that these references can change as a result of different working positions or the mirror-symmetrical design or the like.

In the Figure 1 is denoted by the reference numeral 1 as a whole a household appliance in the form of a refrigerator or freezer. This refrigerator or freezer 1 comprises a body 3 on which a door 2 is rotatably mounted. A bearing element 6 fastened to the body 3 of the household appliance 1 is used to support the door 2, as is shown, for example, in FIG Figure 4 is shown and with which the door 2 is rotatably fixed on the body 3 of the household appliance 1.

In the with the reference number 5 in Figure 1 A locking device 10 is arranged, by means of which the door 2 can be moved by a drive part over a certain pivoting range in the closing direction. A force accumulator 11, for example a spring designed as a compression spring, is preferably used as the drive part.

Other configurations of the drive part are also conceivable. For example, the drive part can also be designed as an electrical drive part, in particular as an electric motor.

A preferred embodiment of this locking device 10 is shown in FIG Figure 3 shown. At the in Figure 3 shown locking device, which will be discussed in more detail later, in addition to the locking device 10 also a damper 20 is included, both the locking device 10 and the damper 20 are coupled to a rotary movement of the door about the bearing axis 4 receiving first rotary element 7, which has an axis of rotation 71 which is essentially parallel to the bearing axis 4 of the door 2.

The first rotary element 7 and the door 2 are used to transmit a rotary movement from the first rotary element 7 to the door 2 or vice versa Connected to one another via a compensation device to compensate for an offset or angular offset between the axis of rotation 71 of the first rotary element 7 and the bearing axis 4 of the door.

A compensation device not according to the invention is shown in Figure 4 shown. Here, the compensation device has a driver 9 that can be attached to the door 2 in a rotationally fixed manner and coupled with the first rotary element 7 in a rotationally fixed manner.

As in Figure 4 As can be seen, the bearing element 6 is fixed in place on the body 3 of the household appliance, for example screwed to the body with screws 61. On an arm 62 of the bearing element 6 protruding in the direction of the door 2, a bolt 63 is arranged at its end which is spaced from the body 3 and rests in a first recess 43 of the door 2.

Another such bearing element 6 is fastened to the body 3 in the area of the bottom of the household appliance, the bolt 63 protruding upward into a bottom opening of the door 2 into a corresponding recess 43 (not shown) and so the door can be rotated about a bearing axis 4 on the body of the household appliance 1 holds.

The driver 9 is attached, in particular inserted, into a second recess 42. The part of the driver 9 that can be inserted into the recess 42 of the door 2 (shown in FIG Figure 6 ) is fixed in the recess 42 of the door 2 in a rotationally fixed manner.

The second end of the driver 9 is non-rotatably connected to the first rotary element 7 of the locking device 10. The driver 9 inserted into the recess 42 of the door can compensate for a vertical lowering of the door 2 without interrupting the transmission of the rotary movement of the door 2 via the driver 9 to the first rotary element 7 of the locking unit 10.

A possible displacement of the plug-in piece 92 of the driver 9 to the recess 42 of the door 2 is also provided to compensate for misalignments of the axis 4 of the door 2 with respect to the axis 71 of the first rotary element 7 or the axis 84 of the second rotary element 8.

According to a particularly preferred embodiment, shown in FIG Figures 5 to 8 , the driver 9 has a rotationally fixed to the first rotary element 7 couplable bolt 93. The bolt 93 is non-rotatably connected to the first rotary element 7.

A driver arm 91 of the driver 9 is held on the bolt 93 so that it can be tilted in an angular range between preferably 75 ° and 105 ° to the axis of rotation 71 of the first rotary element 7. The driver arm 91 is, as in the Figures 5 , 6th and 8th can be seen, roughly roof-shaped with two legs arranged at obtuse angles to one another and rests on a crown 95 that is also roof-shaped surrounding the bolt 93, the apex of this ring 95 forming a tilting edge for the driver arm 91 and thus an angular offset between the axis of rotation 71 of the first rotary element 7 and the axis of rotation 4 of the door 2 are able to compensate.

As in the Figures 6 to 8 As shown, a connection piece 94 extends from the roof-shaped driver arm 91, from which a paddle-shaped plug 92 of the driver is arranged vertically downwards and can be inserted into the recess 42 in the door 2.

As in Figure 8 As is shown, this recess 42 is dimensioned larger than the insert piece 92 of the driver 9 in order to also enable a tilting movement and a sliding movement of the driver in the recess 42 of the door 2.

As in Figure 8 and Figure 4 Furthermore, it can be seen that the bearing element 6, from which an arm 62 extends towards the door 2, is not connected to the driver 9. A bolt 63 extends from the arm 62 of the bearing element 6 down to the door 2, which bolt serves as a bearing bolt of the door and is received in the first recess 43 of the door.

In a further embodiment not according to the invention, shown in FIG Figure 9 , the driver 44 is designed as a non-rotatable bolt that can be received in the door 2 in the bearing element 6. For this purpose, a sleeve 64 is provided in the bearing element 6 in the area of the bearing arm 62, which sleeve can rotate in the recess 43 of the door. The driver 44 is pushed through the sleeve 64 and one end is held non-rotatably on the door 2. The inner diameter of the sleeve 64 is dimensioned so that there is sufficient air to the driver 44 so that no contact occurs between the sleeve 64 and the driver 44 even if a misalignment or angular misalignment occurs. The other end is the The driver 44 is held in a rotationally fixed manner in the first rotary element 7 of the locking device 10.

In order to enable an angular deviation of the axes of rotation here as well, as in Figures 10 and 11 shown, the end 45 of the driver 44, which is held non-rotatably on the first rotary element 7, can be tilted by a predetermined angle about the axis of rotation 71 of the first rotary element 7.

For this purpose, the end piece 45 of the driver 44 is preferably spherical in shape. A special variant of the design of the spherical end 45 of the driver 44 is shown in the plan view in Figure 11 shown. The end piece 45 of the driver 44 is supported or received in the first or second rotary element 7, 8 in a form-fitting manner in the direction of rotation of the first or second rotary element 7, 8. The circumferential contact surfaces of the end piece 45 are spherical so that even with an angular offset between the axis of rotation of the first or second rotary element 7, 8 and the longitudinal axis of the driver 44, a rotary movement can be transmitted from the rotary element 7, 8 to the driver 44 and thus an angular offset between the bearing axis 4 of the door and the axis of rotation 71 of the first rotary element 7 is made possible.

It is also conceivable for the end piece of the driver 44 protruding into the door 2 to be correspondingly spherical, so that the driver 44 is additionally or alternatively held in the recess 42 of the door 2 so that it can be tilted.

In the Figures 12 to 15 Several design variants of a compensation device are shown, which are able to compensate for a horizontal offset between the bearing axis 4 of the door 2 and the first rotary element 7 of the locking device 10.

For this purpose, the compensation device according to FIGS Figures 12 to 15 at least one second rotary element 8, coupled to the first rotary element 7 and transmitting the rotary movement, the second rotary element 8 being arranged offset to the first rotary element 7 in a plane that is essentially parallel to the bearing axis 4. The axis of rotation 84 of the second rotary element 8 is preferably the same as the bearing axis 4 of the door, but can also be different from this, for example when combined with a driver 9 according to FIG Figures 4 to 8 , in which the driver 9 is fixed outside the axis of rotation 4 of the door 2 on the door 2 and transmits the rotary movement to the second rotary element 8.

For the transmission of a horizontal axis offset dx is used according to Figure 12 a toothed belt 81 which connects the first rotary element 7 to the second rotary element 8 and with which larger distances between the axes of rotation 4, 71 of the door and the rotary element 7 driving or driven by the locking device 10 can be bridged.

At the in Figure 13 The embodiment variant shown, the first rotary element 7 and the second rotary element 8 are connected to one another via a coupling rod 82, which ensures an equal rotation of the two rotary elements. If the rotary movement is so great that the dead centers of the rotary elements are passed over by the coupling rod 82 in the 180 ° extended position, there is a risk of the direction of rotation of a rotary element being switched. In order to prevent this, the coupling rod 82 has an elongated hole in which a bolt is guided, which is arranged on a pivot lever which is rotatably mounted on the locking device 10.

At the in Figure 14 The first and second rotary elements 7, 8 shown are designed as gears, which are connected to one another via a third rotary element 83, also designed as a gear, in order to maintain the direction of rotation between the first rotary element 7 and the second rotary element 8.

By choosing the number of teeth of the rotary elements 7, 8, 83, the transmission ratio of the door drive to the locking device is determined.

A ratio of 1: 1 is preferably selected in order to be able to use the same components for the other components of the locking device as in an embodiment variant of a locking device in which the first rotary element 7 is not designed as a gear.

At the in Figure 15 The embodiment variant shown, the first and second rotary elements 7, 8 are also designed as gears, whereby here due to the reversal of the rotary movement by the only two inserted gears, the transfer of the rotary movement to the locking device 10 or from the locking device to the rotating elements 7, 8 must be observed .

This reversal of the rotary movement can also be used deliberately to reverse the operation of the locking device 10 on the door 2, so that, for example, the door 2 is damped when opening, in sections before reaching the end position in the open position, instead of during the closing movement or the opening movement of the door 2 is supported by the closing device 10.

With a corresponding selection of a transmission ratio of the two rotary elements 7, 8 designed as gear wheels, for example in a transmission ratio of 1: 2, the rotary movement of the door 2 can be reduced, for example, from 130 ° to 65 ° on the first rotary element 7.

An inventive variant of the locking device, in which a damper is also integrated, is explained below.

The closing device 10 comprises a spring 11 designed as a compression spring, which is clamped between two end pieces 12 and 13. A first end piece 12 is mounted on the housing 5 so as to be rotatable about an axis 16. On the opposite side, the end piece 13 is mounted about an axis 17 which is arranged on a rotatable actuating part 18. The rotatable actuating part 18 is rotatably mounted on the housing 5 about the axis 19. The spring 11 is guided around a sleeve 14 which can be pushed onto a rod 15 in order to be able to compensate for the length between the two end pieces 12 and 13.

In the housing 5, the damper 20 is also provided, which is designed as a linear pressure damper with a housing 21 and a piston rod 22. The piston rod 22 can be pushed into the housing 21, with high damping forces being provided by a corresponding piston when the piston rod 22 is pushed in, while the piston rod 22 is pulled out smoothly.

The housing 21 is fixed to a holder 24 which is mounted on the housing 5 so as to be rotatable about an axis 25. The piston rod 22 is connected on the opposite side via a holder 26 to a pivoting part 28, the holder 26 being rotatably mounted about an axis 27. The pivot part 28 is mounted on the housing 5 so that it can rotate about the axis 19, on which the actuation part 18 is also mounted, the actuation part 18 and the pivot part 28 being able to be rotated about the axis 19 independently of one another.

To actuate the locking device 10 and the damper 20, a cam guide 30 is provided, which is arranged on the bearing axis 4 in a rotationally fixed manner. The cam guide 30 comprises a plurality of control projections 31, 32 and 33 which act on the actuating part 18 and the pivoting part 28. For this purpose, a roller 40 is rotatably mounted on the actuating part 18, while a roller 41 is rotatably supported on the pivoting part 28. Alternatively, the rollers can also be replaced by sliding elements, so that a process with as little friction as possible between the control projections and the actuating part or pivoting part 28 is ensured.

A latching mechanism is also provided in the housing 5 in order to latch the locking device 10 in a tensioned position, the latching mechanism comprising a pivotable latching pawl 35 which is rotatably mounted on the housing 5 about the axis 38.

If the door 2 is now opened from the closed position, as shown in Figure 3 is shown, the bearing axis 4 rotates the cam guide 30 counterclockwise so that the first control projection 31 acts on the roller 40 in order to tension the spring 11 of the locking device 10. At the same time, in the pivoting range between the closed position and an opening angle of between 20 ° and 60 °, the damper 20 is released by rotating the control projection 31, whereby the pivoting part 28 rotates about the axis 19 clockwise until the pivoting part 28 hits a stop 42 of the housing comes to rest. The pulling out of the piston rod 22 from the housing 21 and the associated pivoting of the pivoting part 28 takes place by means of the force of a spring 23 which is arranged between the holder 26 and the holder 24.

When the door 2 is opened, the damper 20 between the holder 24 and the holder 26 does not initially change its length when the locking device 10 is further tensioned by the control projection 31 acting on the roller 40 and rotating the actuating part 18 further clockwise to compress the spring 11 of the locking device 10.

When the door is opened between an opening angle of 35 ° and 50 °, a control cam 34 of the locking mechanism also comes into engagement with an arm 37 of the locking pawl 35, so that the latter is rotated about the axis 38. As a result, a second arm 36 of the essentially V-shaped latching pawl 35 is pivoted towards the actuating part 18. The control cam 34 rotates the Locking pawl 35 against the force of a spring 39 which biases the locking pawl 35 into the unlocked position.

If the door 2 is now pivoted further in the opening direction, the arm 36 comes into engagement with the end piece 13 in order to lock the locking device 10. The control cam 34 now leaves the arm 37, the control projection 31 being designed in such a way that the spring 11 relaxes slightly when it is locked in order to lock onto the arm 36 so that the roller 40 can be lifted off the control projection 31.

If the door 2 is now moved further in the opening direction, for example up to an opening angle of about 100 °, the door 2 moves freely, ie. H. neither the closing device 10 nor the damper 20 exert closing or opening forces on the door 2. This is due to the fact that the locking device 10 is locked on the latching pawl 35 and remains stationary, while the damper 20 rests against the stop 42 and is also arranged in a stationary manner.

If the door 2 is now moved further in the opening direction, a further control projection 33 of the cam guide 30 comes into engagement with the pivoting part 28 and / or the roller 41 in order to rotate the pivoting part 28 counterclockwise. As a result, the damper 20 is compressed and the piston rod 22 moves into the housing 21, whereby damping forces are generated. During a movement from an opening angle of approximately 155 ° to the maximum opening position of approximately 180 °, the damper 20 is compressed as a result. The locking device 10 is still in the locked position and therefore does not exert any forces on the door 2. Opening angle maximum 90 ° to 180 °.

If the door 2 is now moved from the maximum opening position in the closing direction, the damper 20 is first moved apart again from the compressed position, the movement being carried out by the spring 23, so that the user does not have any forces from the extension of the damper 20 when closing the door 2 feels. The door 2 is now moved further in the closing direction until the control projection 31 comes to rest against the roller 40 of the actuating part 18 at an opening angle of about 60 ° to 70 ° and at the same time the control cam 34 abuts the arm 37 of the latch 35. By slightly compressing the spring 11 of the locking device 10 and pivoting the latch 35 by the control cam 34, the latch can be moved into the unlocked position in that the latch 35 is pivoted about the axis 38 by the force of the spring 39.

If the door 2 is now moved further in the closing direction, the control projection 31 comes into engagement with the roller 41 at a closing angle between 20 ° to 60 ° in order to pivot the pivoting part 28 counterclockwise and thereby move the damper 20 into the compressed position . As a result, damping forces are also generated when the door 2 is closed. At the same time, the locking device 10 is effective, since it was unlocked via the control cam 34, so that the spring 11 now rotates the actuating part 18 counterclockwise around the axis 19, the roller 40 running on the back of the control projection.

If the door 2 is closed beyond an angle of 0 ° due to manufacturing tolerances, this is also possible with the bearing arrangement shown, a further control projection 32 being provided on the control cam for this purpose in order to keep the maximum closing forces low.

In the exemplary embodiment shown, the actuating part 18 of the closing device 10 and the pivoting part 28 of the damper 20 are partially actuated via the same control projections 31, which form a common control cam. It is of course also possible to provide two separate control cams on the bearing axis 4, one control cam being responsible exclusively for the actuating part 18 and the second control cam exclusively for the pivoting part 28. Furthermore, it is possible that the actuating part 18 and the pivoting part 28 are not mounted via a common axis 19. Each of these components can also have its own axis.

The shape of the control projections 31, 32 and 33 can be matched to the respective application. For example, it is possible to make the damping forces greater in an angular range shortly before reaching the maximum closed position than in an opening range between 20 ° and 30 °. In addition, the spring 11 of the closing device 10 can also be controlled via the cam guide 30 in such a way that the closing forces are kept low in the closed position in order to keep the forces on the seals low, while the closing forces are designed to be greater in a slightly open area. Depending on the embodiment of the invention, the bearing axis 4 can be designed as a separate bearing axis. This means that the bearing axis is already attached to the door during assembly, for example, and the bearing arrangement is attached to the bearing axis is attached so that the bearing axis is indirectly connected to the cam guide.

The bearing arrangement described can be used on a right or left side of a piece of furniture or household appliance 1 without the need for special right or left components.

It is also conceivable, but not according to the invention, to fasten the locking device 10 on or in the door, in which case the driver 9, 44 must be supported on the body 3 of the furniture.
