Description

The present invention relates to a door fitting for at least one door leaf of a piece of furniture, with a housing on which a drive lever is rotatably mounted, via which the at least one door leaf can be moved, wherein the drive lever is prestressed in the direction of a maximum opening position and/or a maximum closing position by means of a force accumulator which can be prestressed for opening and/or closing the at least one door leaf, wherein at least one damper is mounted on the housing, and to a piece of furniture.

DE 10 2016 120 673 A1 shows a piece of furniture with a furniture body and a door, which comprises at least two hinged door leaves. The door can be opened by means of a door fitting, which is an opening device, which comprises a drive lever, which is pre-tensioned by means of a gas pressure spring so that the door leaves are pre-tensioned in the opening direction.

The problem with state-of-the-art furniture is that when the door is opened using door fittings, the door leaves may bang together violently and the furniture and fitting parts may be subjected to excessive stress, which may damage components of the furniture, particularly the door fittings, and may result in loud, unwanted impact noises.

Based on this, it is the object of the present invention to provide an improved door fitting.

The present invention solves this problem with a door fitting having the features of claim 1.

According to the invention, the door fitting for at least one door leaf of a piece of furniture comprises a housing on which a drive lever is rotatably mounted, on which the at least one door leaf can be pivotally mounted, wherein the drive lever is prestressed in the direction of a maximum opening position and/or a maximum closing position by means of a permanently acting force accumulator which is prestressed to open the at least one door leaf, wherein at least one damper is mounted on the housing.

In the unidirectional variant, the spring system is maximally pre-tensioned when the door is completely closed. In the bidirectional variant with opening and closing damping, the maximum pre-tension is when the drive lever is at an opening angle of approx. 15°-20°. The spring system relaxes in both directions and closes or opens the doors from this dead center. The drive lever has a projection which can actuate at least one damper when at least one door leaf moves into the maximum opening position by pressing against at least one damper slide, so that movement of the drive lever is delayed before reaching the maximum opening position, whereby movement of the drive lever into the maximum closing position can be braked before reaching the maximum closing position by means of the at least one damper.

This allows the movement of the drive lever and thus in particular of at least one door leaf to be braked into the maximum opening and the maximum closing position using at least one damper, which is used bidirectionally, i.e. for both opening and closing damping. This prevents hard impacts, particularly of the door leaf, so that the load on the door fitting is reduced, thereby increasing its service life, and at the same time loud impact noises when the door leaf moves can be prevented.

In the sense of the present invention, the maximum opening and closing position refers to the respective positioning of the individual components of the door fitting and/or the furniture in a maximum opening and closing position of the at least one door leaf and/or the drive lever relative to the housing or the furniture body.

The door fitting is in particular a drive or an opening and/or closing device for at least one door leaf.

Preferably, a damper housing of the at least one damper is arranged on the housing so that it can rotate on a central axis with radial play by means of at least one central bolt. In particular, the central bolt can be arranged in at least one opening in at least one side of the housing of the door fitting. This allows the at least one damper to also move when the drive lever moves and at the same time enable the central bolt to move. The movement of the central bolt can also be possible in the axial direction, in particular, so that the central bolt can be at least partially pulled out of the housing.

In one embodiment of the present invention, at least one of the at least one damper slide and/or at least one damper piston is actuated by means of the at least one central The locking bar can be fixed to the damper housing and/or detached from the damper housing by means of an axial movement of the same. This makes it possible to adjust damping or braking of a movement of the drive lever depending on the weight of at least one door leaf.

The at least one middle latch can preferably be arranged in at least one opening on the housing in an axially adjustable manner by means of at least one notch, which can be fixed in a locking manner to at least one projection on an inner side of a tunnel formed on the damper housing. This allows different settings of the at least one damper, whereby activation and/or deactivation of at least one of the dampers can be possible to brake the movement of the drive lever.

Preferably, a damper housing of the at least one damper is mounted by means of at least one lateral pin so as to be rotatable on a lateral axis on the housing and/or on at least one pivot arm mounted on the housing so as to be pivotable about an outer axis. This allows the damper, in particular the damper slide, to be secured against falling out of the housing and/or the damper housing, for example.

According to a preferred embodiment, the drive lever has a pin which is in particular fixed and/or inserted on the drive lever and which runs in a first curve which is formed in the housing.

When the at least one door leaf moves into a maximum closed position, the outer pin can actuate the at least one pivot arm and pivot it about the axis so that the lateral pin on the pivot arm can actuate the at least one damper by pressing against the at least one damper slide. As a result, a movement of the drive lever can be braked before the maximum closed position is reached, whereby a movement of the drive lever can be braked or dampened both before the maximum opening position is reached and before the maximum closed position is reached by means of the same at least one damper.

The drive lever and/or the pin arranged on the drive lever can each be pivotable in a range which in particular corresponds to a circular arc extending from the main axis, which can in particular be predetermined by the first curve in the housing, with a radian measure of π/4 to π and preferably of π/3 to π/2.

The pin on the drive lever can in particular press against a pivoting contour on the pivot arm and thus pivot the pivot arm, whereby the damper is actuated by a movement of the damper slide mounted on the pivot arm.

The swivel arm and/or a position of the lateral axis and/or the at least one lateral pin can each be swiveled in a range, which in particular corresponds to a circular arc extending from the outer axis, which can in particular be predetermined by a second curve in the housing, with a radian measure of π/4 to π and preferably of π/3 to π/2. As a result, a damping stroke of the at least one damper can be predetermined, in particular during an opening movement of the door fitting.

The middle latch, which is preferably arranged on the damper, moves when the swivel arm and/or the drive lever pivots, particularly in the axial direction, within the opening in the housing in which it is arranged, so that it can pivot freely. This can additionally or alternatively limit the range within which the damper can pivot.

In particular, the at least one damper, in particular the damper housing, can be mounted on the housing so as to be rotatable about the central axis and/or about the lateral axis and/or about a further axis at the end of the at least one damper opposite the damper slide in order to enable effective actuation of the at least one damper.

Preferably, the at least one damper is designed to be self-extending so that it can be actuated from a maximum closing position during an opening movement of the drive lever.

In a preferred embodiment of the present invention, exactly two dampers are mounted on the housing, wherein one of two damper pistons can be fixed to the damper housing by means of a central latch, in particular by axially displacing the central latch, and/or can be released from the damper housing, so that alternatively one or both of the two dampers can brake a movement of the drive lever before reaching the maximum opening position and/or before reaching the maximum closing position.

At least one of the dampers is preferably removable from the housing, in particular especially after pulling the middle latch out of the tunnel on the damper housing.

The drive lever can preferably be pivoted by means of a pressure roller mounted on a pre-tensioned steering element that is connected to the energy storage device in an articulated manner and runs on a curved guide on the drive lever. This enables effective movement transmission, which reduces the load on the door fitting.

For a movement to the maximum opening position, the energy storage device, in particular a spring, presses against the steering element so that the pressure roller can emerge from a starting position in the maximum closing position on the curve guide via a movement initiated by the pivoting steering element and roll along the curve guide until the maximum opening position is reached. Conversely, the direction of the torque is changed by the curve guide when a dead center is exceeded. For a movement to the maximum closing position, the energy storage device presses on the steering element so that it pivots in the opposite direction and the pressure roller runs back along the curve guide. By using a spring for the described movement of the drive lever, at least one door leaf can be easily opened and closed.

The energy storage device comprises, for example, at least one coil spring, which can be fixed in particular in an articulated manner to the housing, so that the drive lever can be easily preloaded.

For effective use, the energy accumulator is compressed for pre-tensioning in the direction of the maximum opening position and relaxes during an opening movement of at least one door leaf, in particular in the stretching direction of the coil spring, so that in a maximum opening position it is pre-tensioned in the direction of the maximum closing position.

The door fitting is preferably made predominantly of metal, whereby the door fitting, in particular the damper, can additionally or alternatively also comprise plastic, so that the door fitting can be easy to manufacture and robust.

The present invention also includes a piece of furniture that includes a furniture body that can be closed at an opening by at least two hingedly connected door leaves that can be moved from an unfolded, preferably flush-fitting closed position to a folded-up open position, wherein the furniture includes at least one door fitting, wherein for an opening process a force impulse acting against the holding device releases the door leaves in the opening direction. The movement of the door leaves during the opening process is braked before an opening position is reached by means of at least one damper actuated by the drive lever, wherein a movement of the drive lever into the maximum closed position can be braked before the maximum closed position is reached by means of the at least one damper.

In one embodiment, a holding device can be provided which holds a drive lever of the at least one door fitting in a closed position against the force of a force accumulator. By using a spring in particular for the described movement of the drive lever, the at least one door leaf can be easily opened.

In particular, the holding device can be provided in a connecting region of the door leaves, wherein the connecting region is the region which is arranged adjacent to a hinge axis at which the two door leaves are connected to one another.

Preferably, the furniture includes guide rails in which the door leaves can be guided.

1A shows an isometric view of a piece of furniture according to the invention, which comprises a furniture body which can be closed at an opening by at least two hingedly connected door leaves 4, 5, which can be moved from a folded-out, preferably flush-fitting, closed position into a folded-up opening position. In 1A a pair of door leaves 4, 5 is shown in a maximum opening position and in a maximum closing position. The furniture 1 comprises at least one door fitting 10, wherein optionally a holding device for the door leaves 4, and also optionally 5, can be provided, which can be arranged in particular on an upper floor 7 or a lower floor 6 of the furniture. Preferably, the at least one door fitting 10 is arranged on side walls 3 of the furniture. The furniture 1 also has a rear wall 8.

In 1B is a plan view of the furniture 1 from above, in which the at least one door fitting 10 is visible in an opening position of the door leaves 4, 5. In 1C a front view of a piece of furniture 1 according to the invention is shown.

Optionally, the furniture can include guide rails 9 in which the door leaves 4,5 are guided.

2A shows a side view of a door fitting 10 according to the invention, as shown for example in 1A to 1C can be used, in a maximum opening position. The door fitting 10 comprises a housing 11 on which a drive lever 12 is rotatably mounted, on which the at least one door leaf 4, 5 can be moved, which is optionally attached to a holding element 17, which can be attached in particular in an articulated and/or displaceable manner to the drive lever 12. The drive lever 12 is prestressed in the direction of a maximum opening position and/or a maximum closing position by means of a force accumulator 31, which is prestressed for opening and/or closing the door leaf 4, wherein at least one damper 21 is mounted on the housing 11, for example on an axis 47 by means of a pin 26.

The drive lever 12 is pivotably mounted about a main axis 41 on the housing 11, for example by means of at least one pin, wherein the drive lever 12 has a pin 15 which is fixed in particular in the drive lever 12 by insertion and which is guided within a particularly substantially arcuate first curve 181.

At least one pivot arm 14 is mounted on the housing 11, pivotable about an outer axis 44, on which a pin 25 is mounted on a lateral axis 43, which can be moved within a second curve 182 when the pivot arm 14 is pivoted. The pivot arm 14 also has a pivot contour 141. A damper 21 is also mounted on the housing 11 on a pin 26 on an axis 47. The damper 21 also has a tunnel 28, into which a central latch 24 is inserted on an axis 42, which is arranged within at least one opening 16a in the housing 11.

2B shows a top view of the door fitting 10 in 2A The door fitting 10 has two pivot arms 14 which are arranged on the housing 11. The middle bolt 24 is inserted laterally through the housing 11. A force accumulator 31, within which a guide 32 is arranged, presses due to its pre-tension against a steering element 19, by means of which the drive lever 12 is pressed into an opening position.

As in 2B or even in 1B As can be seen, the drive lever 12 and/or the at least one door leaf 4, 5 in the maximum opening position is optionally substantially at an angle to a longitudinal extension of the housing 11, which runs along the pivoting movement of the drive lever 12, of more than 90°, in particular of more than 180°. 2C shows a front view of the door fitting 10 from 2A .

In 2D the door fitting 10 from the previous figures is shown in an isometric plan view in a preferred orientation, with a substantially horizontal arrangement of the drive lever 12, for mounting on the furniture 1 in a maximum opening position of the door leaves 4, 5. The door leaves 4 are fastened to the holding element 17 by means of several, in this case four, fastening means, here screws, which is connected in an articulated manner to the drive lever 12 via a moving element, for example a pin, which can be moved in a guide rail formed in the holding element 17 and which is mounted on the housing 11 so as to be pivotable about the main axis 41.

The pin 15 runs in the arcuate first curve 181, which is essentially in the form of a circular arc extending from the main axis 41 with a radian measure of π/4 to π and preferably of π/3 to π/2. The pivot arms 14 are partially angled and have the pivot contour 141.

In addition, the pivot arms 14 can pivot in an articulated manner on the outer axis 44 on the housing 11, so that the outer pin 15 arranged on the pivot arms 14 moves within the arcuate second curve 181, which is formed in the pivot arms 14 essentially in the form of a circular arc, optionally starting from the outer axis 44, with a radian measure of π/4 to π and preferably of π/3 to π/2.

The middle latch 24, which, as shown in the previous figures, is arranged within the opening 16a, is also arranged within the opening 16b in the housing 11 with radial play and can be at least partially pulled out of the housing 11.

3A to 3D essentially correspond to the 2A to 2D , the door fitting 10 is shown in a maximum closing position of the drive lever 12. The drive lever is pivoted on the main axis 41 to 2A The holding element 17 is articulated on the drive lever 12 so that the drive lever 12 is at the other end of the guide rail than in 2A shown, arranged.

The energy accumulator 31 is in a more compressed state than it is in 2A is pre-tensioned and presses against the drive lever 12 by means of the steering element 19, so that the latter is pre-tensioned to move in the opening direction. The pivot arms 14 are pivoted in the maximum closing position to the other end of the second curve 182 than in the maximum opening position in 2A , so that the pin 25 is also arranged at this point. The projection 13 on the drive lever 12, which can actuate the at least one, here two, dampers 21 at the end of the drive lever 12 opposite the holding element 17, is in 3A visible.

When the pin 25 moves into the maximum closing position, the damper 21, in particular the damper housing 23, pivots on the axis 47. As a result, the middle bolt 24, which is inserted into the tunnel 28, and thus the axis 42, are radially offset from their position in the maximum closing position within the openings 16a and 16b. 2A to 2D arranged on the housing 11. Optionally, the damper can be designed to be self-extending.

When the at least one door leaf 4, 5 moves into a maximum closing position, the pin 15 on the drive lever 12 can actuate the pivot arm 14 and pivot it about the outer axis 44, so that the lateral pin 25 on the pivot arm 14 can actuate the at least one damper 21 by pressing against the at least one damper slide 22, so that a movement of the drive lever 12 can be braked before the maximum closing position is reached.

4A and B show two sectional views of the 3A , i.e. the condition of the door fitting 10 from 3A to 3D . The damper 21, which is designed as a linear damper, is shown in an extended state, i.e. with the extended damper slide 22 and damper piston 27, which can be extended and/or retracted from and/or into the damper housing 23, which is pivotably mounted on the pin 26 on the axis 47 and which has the tunnel 28 with the inserted latch 24. The damper slide 22 can be pivoted on the pin 25 about the lateral axis 43.

The steering element 19 is mounted on the housing 11 by means of a pin 37 so that it can pivot about an axis 45 and has a pressure roller 36 which is mounted on a pin 35 on the steering element 19. The pressure roller 36 runs on a curved guide 122 on the drive lever 12 so that the force acting on the steering element 19 from the energy accumulator 31, which is mounted on a pin 34 on an axis 46 on the housing 11, acts on the steering element 19 so that it can pivot on the axis 45 and thus preload the drive lever 12 in the direction of its opening position. The energy accumulator 31 is arranged on a guide 32 and is also connected to the steering element 19 in an articulated manner, here on an axis 48 by means of a pin 33.

Pivoting the drive lever 12 leads to a relaxation and/or an expansion of the energy accumulator 31 during a movement into the opening position. The drive lever 12 pivots on the main axis 41 by pivoting the steering element 19, which can be predetermined in particular by the energy accumulator 31, so that the projection 13 and/or the pressure contour 121 of the drive lever 12 presses against the damper slide 22 and thus actuates the damper 21, which brakes the movement of the drive lever 12, wherein the damper 21 pivots on the axis 47 so that the latch 24 moves in the radial direction perpendicular to the axis 42.

In 5A to 5C Such a movement of the drive lever 12 in a maximum opening position sition. The pins 15 and 25 move within the curves 181 and 182, whereby the curve 181 specifies the maximum opening position of the drive lever 12 and whereby the swivel arm 14 swivels about the outer axis 44 by movement of the pin 25 which is articulated on the lateral axis 43.

6A and 6B show a view of the maximum opening position of the drive lever 12 from the previous figures, wherein the projection 13 on the drive lever 12 holds the damper slide 22 in a maximum actuated position of the at least one damper 21. The steering element 19 is also shown in a pivoted position, so that the pressure roller 36 is arranged at one end of the curve guide 122. The energy accumulator 31 has in 6A one compared to 4A stretched state.

For a movement into the maximum opening position, the energy accumulator 31, which is preferably a spring, in particular a helical spring, presses against the steering element 19 so that the pressure roller 36 can emerge from a rigid positioning in the maximum closing position on the curved guide 122 via a movement initiated by means of the pivoting steering element 19 and can roll along the curved guide in the direction of the pressure contour 121 and/or the projection 13 until the maximum opening position is reached. Conversely, for a movement into the maximum closing position, the energy accumulator 31 pulls on the steering element 19 so that it pivots in the opposite direction and the pressure roller 36 runs back along the curved guide 122.

7A to 7C show the area of the main axis 41 enlarged in several views for a maximum closing position of the drive lever 12. The pin 15 is offset in comparison to the maximum opening position and the swivel arms 14 are swiveled. The pin 15 rests on the swivel contour 141 of the swivel arms 14.

In 8A to 8C It is shown in detail how the swivel arms 14 are connected to the damper slide 22 by means of the pin 25. It is particularly 8C visible how the pin 15, which is arranged on the drive lever 12 according to the other figures, can actuate the pivot arm 14 when the drive lever 12 moves into a maximum closing position and pivot it about the outer axis 44, so that the lateral pin 25 on the pivot arm 14 can actuate the at least one damper 21 by pressing against the at least one damper slide 22, so that a movement of the drive lever 12 can be braked before reaching the maximum closing position. In this embodiment, the damper slide 22 is connected directly to the pin 25 by the pin 25 being guided through an opening in the damper slide 22.

9 shows an exploded view of the components of the door fitting 10.

In 10A to 10C the latch 24 from the previous figures is shown. The pin has at least one, here two, notches 241 and, in particular on a side opposite the notches 241, a projection 242.

11A to 11D show the damper housing 23. The tunnel 28 into which the latch 24 can be inserted is formed on the damper housing 23. The tunnel 28 has at least one projection 281. The damper housing 23 comprises receptacles 29 for two dampers 21, one of the receptacles 29 having a recess 282 in the damper housing 23.

In 12A to 12C it is shown how the latch 24 can fix a damper piston 27 to the damper housing 23 and/or release it from the damper housing 23 by means of axial displacement within the tunnel 28. The latch 24 can be locked in various positions on the tunnel 28 by means of the notches 241 on the projection 281. In the position of the latch 24 pushed further into the tunnel 28, the projection 242 on the latch 24 enters the recess 282 in the damper housing 23 in the area of the tunnel 28 in such a way that it fixes a damper piston 27 to the damper housing 23 in such a way that it does not contribute to the braking of the drive lever 12. In the position of the latch 24 pushed in less far, the damper piston 27 is released so that it contributes to the braking of the drive lever 12.

For example, in 8C and 12B it is clearly visible that the damper housing 23 has a special contour in the area of the receptacles 29 in one receptacle 29, which the damper slide 22 also has as a negative. If the one damper 21, which is guided in the receptacle 29 with the contour, is deactivated, the damper slide 22 moves up again with both receptacles for the damper 21 during the movement of the door fitting 10, although only one damper is guided in the slide. The deactivated damper 21 is completely located in the damper housing 23. In order for the damper slide 22 and the damper housing 23 to meet each other precisely shortly before the end positions, even without the damper 21 in one of the damper slides 22, this complementary contour on the damper slide 22 and that of the one receptacle 29 of the damper housing 23 is advantageous. The slanted edges act as an inlet guide and an anti-twisting device.

In 13A and 13B a further embodiment of a piece of furniture 1 according to the invention is shown, which comprises two door leaves 4, 5, wherein the door leaf 4 is supported in a maximum closed position by means of several holding elements on side walls 3 of a furniture body 2. A holding element 17 of a door fitting 10 according to the invention is mounted on the door leaf 4, which is movable via a drive lever 12. The door leaf 4 is connected in an articulated manner to the door leaf 5, which is guided in a guide rail 9. Optionally, a holding device can be mounted on the door leaf 5 and an upper floor 7 of the furniture 1.
