[0001] Door fittings and furniture
[0002] The present invention relates to a door fitting for at least one door leaf of a piece of furniture, having 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.
[0003] DE 10 2016 120 673 A1 discloses a piece of furniture with a furniture body and a door comprising at least two hinged door leaves. The door can be opened by means of a door fitting, which is an opening device comprising a drive lever pre-tensioned by a gas spring so that the door leaves are pre-tensioned in the opening direction.
[0004] 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 fittings may be subjected to excessive stress, which may damage components of the furniture, particularly the door fittings, and cause loud, unwanted impact noises.
[0005] Based on this, it is the object of the present invention to provide an improved door fitting.
[0006] The present invention solves this problem with a door fitting having the features of claim 1.
[0007] 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 mounted, in particular pivotably, wherein the drive lever is preloaded in the direction of a maximum opening position and / or a maximum closing position by means of a permanently acting energy accumulator which is preloaded 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 preloaded when the door is completely closed. In the bidirectional variant with opening and closing damping, the maximum preload is at an opening angle of the drive lever of approximately 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 the at least one damper when the at least one door leaf moves into the maximum opening position by pressing against at least one damper slide, so that a movement of the drive lever is delayed before reaching the maximum opening position, wherein a movement of the drive lever into the maximum closing position can be braked by means of the at least one damper before reaching the maximum closing position.
[0008] This allows the movement of the drive lever, and thus in particular of at least one door leaf, to be decelerated to the maximum opening and closing positions using at least one damper, which is particularly bidirectional, i.e., used for both opening and closing damping. This prevents hard impacts, particularly on the door leaf, thus reducing the stress on the door fitting and increasing its service life. At the same time, loud impact noises when the door leaf moves can be prevented.
[0009] In the context 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.
[0010] The door fitting is in particular a drive or an opening and / or closing device for the at least one door leaf.
[0011] Preferably, a damper housing of the at least one damper is arranged on the housing by means of at least one central bolt, rotatable with radial play on a central axis. In particular, the central bolt can be arranged in at least one opening, in particular 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 simultaneously enable a movement of the central bolt. 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 withdrawn from 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 can be fixed to and / or released from the damper housing by means of the at least one central latch, in particular by an axial movement of the same. This allows damping or deceleration of a movement of the drive lever to be adjusted, in particular, depending on the weight of at least one door leaf.
[0012] The at least one central 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 for various settings of the at least one damper, which can enable activation and / or deactivation of at least one of the dampers to brake the movement of the drive lever.
[0013] Preferably, a damper housing of the at least one damper is rotatably mounted by means of at least one lateral pin on a lateral axis of the housing and / or on at least one pivot arm pivotably mounted on the housing about an outer axis. This allows the damper, in particular the damper slide, to be secured, for example, against falling out of the housing and / or the damper housing.
[0014] 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.
[0015] 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. This allows a movement of the drive lever to be braked before reaching the maximum closed position, whereby a movement of the drive lever can be braked or dampened both before reaching the maximum open position and before reaching the maximum closed position by means of the same at least one damper.
[0016] 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 emanating from the main axis, which can in particular be predetermined by the first curve in the housing, with a radian measure of TT / 4 to TT and preferably of TT / 3 to TT / 2.
[0017] 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.
[0018] The pivot arm and / or a position of the lateral axis and / or the at least one lateral pin can each be pivotable within a range, in particular a circular arc extending from the outer axis, which can be predetermined in particular by a second curve in the housing, with a radian measure of TT / 4 to TT and preferably of TT / 3 to TT / 2. This allows a damping stroke of the at least one damper to be predetermined, in particular during an opening movement of the door fitting.
[0019] The central locking bar, preferably arranged on the damper, moves when the pivot arm and / or the drive lever pivots, particularly in the axial direction, within the opening in the housing in which it is arranged, allowing it to pivot freely. This can additionally or alternatively limit the range within which the damper can pivot.
[0020] 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.
[0021] Preferably, the at least one damper is designed to be self-extending so that it can be actuated from a maximum closed position during an opening movement of the drive lever.
[0022] 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 locking bar, in particular by axially displacing the central locking bar, and / or can be released from the damper housing, so that alternatively one or both of the two dampers can decelerate 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 after pulling the central locking bar out of the tunnel on the damper housing.
[0023] The drive lever can preferably be pivoted by means of a pressure roller mounted on a pre-tensioned guide element that is articulated to the energy storage device and runs on a curved guide on the drive lever. This enables effective movement transmission, reducing stress on the door fitting.
[0024] For movement to the maximum opening position, the energy storage device, in particular a spring, presses against the steering element, allowing the pressure roller to 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 torque is changed by the curve guide when a dead center is exceeded. For movement to the maximum closing position, the energy storage device presses on the steering element, causing it to pivot in the opposite direction and the pressure roller to run back along the curve guide. By using a spring for the described movement of the drive lever, at least one door leaf can be conveniently opened and closed.
[0025] The energy storage device comprises, for example, at least one helical spring, which can be fixed in particular in an articulated manner to the housing, so that the drive lever can be easily preloaded.
[0026] For effective use, the energy storage device 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.
[0027] 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 durable.
[0028] The present invention further encompasses a piece of furniture comprising a furniture body which can be closed at an opening by at least two hingedly connected door leaves which can be moved from a unfolded, preferably flush, closed position into a folded open position, wherein the furniture comprises at least one door fitting, wherein for an opening process, a force impulse acting counter to the holding device releases the door leaves in the opening direction. The movement of the door leaves during the opening process is braked before reaching an opening position 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 reaching the maximum closed position by means of the at least one damper.
[0029] In one embodiment, a holding device can be provided that holds a drive lever of the at least one door fitting in a closed position against the force of an energy accumulator. By using, in particular, a spring for the described movement of the drive lever, the at least one door leaf can be conveniently opened.
[0030] In particular, the holding device can be provided in a connecting region of the door leaves, wherein the connecting region is the region arranged adjacent to a hinge axis at which the two door leaves are connected to one another.
[0031] Preferably, the furniture includes guide rails in which the door leaves can be guided.
[0032] The present invention is explained in more detail below with reference to several drawings. They show:

[0045] Figure 1A shows an isometric view of a piece of furniture according to the invention, comprising a furniture body that can be closed at an opening by at least two hingedly connected door leaves 4, 5, which can be moved from an unfolded, preferably flush, closed position to a folded open position. In Figure 1A, a pair of door leaves 4, 5 is shown in a maximum opening position and in a maximum closing position. The piece of 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 a top panel 7 or a bottom panel 6 of the piece of furniture. Preferably, the at least one door fitting 10 is arranged on side walls 3 of the piece of furniture. The piece of furniture 1 also has a rear wall 8.
[0046] Figure 1B shows a top view of the furniture 1, in which the at least one door fitting 10 is visible in an open position of the door leaves 4, 5. Figure 1C shows a front view of a piece of furniture 1 according to the invention. Optionally, the furniture can include guide rails 9 in which the door leaves 4, 5 are guided.
[0047] Figure 2A shows a side view of a door fitting 10 according to the invention, as can be used, for example, in Figures 1A to 1C, 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 fastened to a holding element 17, which can be fastened, in particular, in an articulated and / or displaceable manner to the drive lever 12. The drive lever 12 is preloaded in the direction of a maximum opening position and / or a maximum closing position by means of an energy accumulator 31, which is preloaded for opening and / or closing the door leaf 4. At least one damper 21 is mounted on the housing 11, for example, on an axis 47 by means of a pin 26.
[0048] The drive lever 12 is pivotably mounted on the housing 11 about a main axis 41, 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.
[0049] 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 upon pivoting of the pivot arm 14. 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.
[0050] Figure 2B shows a top view of the door fitting 10 in Figure 2A. The door fitting 10 has two pivot arms 14 arranged on the housing 11. The central latch 24 is inserted laterally through the housing 11. A force accumulator 31, within which a guide 32 is arranged, presses against a guide element 19 due to its preload, by means of which the drive lever 12 is pushed into an opening position.
[0051] As can be seen in Figure 2B or also in Figure 1B, the drive lever 12 and / or the at least one door leaf 4, 5, in the maximum opening position, is optionally located substantially at an angle of more than 90°, in particular more than 180°, to a longitudinal extension of the housing 11, which extends along the pivoting movement of the drive lever 12. Figure 2C shows a front view of the door fitting 10 from Figure 2A.
[0052] Figure 2D shows an isometric plan view of the door fitting 10 from the previous figures in a preferred orientation, with a substantially horizontal arrangement of the drive lever 12, for mounting on the piece of 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. The holding element 17 is articulated to the drive lever 12 via a movement element, for example a pin, which is displaceable 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.
[0053] The pin 15 extends 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 dimension of TT / 4 to TT, and preferably of TT / 3 to TT / 2. The pivot arms 14 are partially angled and have the pivot contour 141.
[0054] 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 arc-shaped second curve 181, which in each of the pivot arms 14 is formed substantially in the form of a circular arc, optionally starting from the outer axis 44, with a radian measure of TT / 4 to TT and preferably of TT / 3 to TT / 2.
[0055] The central latch 24, which, as shown in the preceding 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 withdrawn from the housing 11.
[0056] Figures 3A to 3D essentially correspond to Figures 2A to 2D, with the door fitting 10 being shown in a maximum closed position of the drive lever 12. The drive lever is shown pivoted on the main axis 41 relative to Figure 2A. The holding element 17 is pivotally mounted on the drive lever 12, so that the drive lever 12 is arranged at the other end of the guide rail than that shown in Figure 2A.
[0057] The energy accumulator 31 is preloaded in a more compressed state than in Figure 2A and presses against the drive lever 12 by means of the steering element 19, so that the latter is preloaded to move in the opening direction. In the maximum closed position, the pivot arms 14 are pivoted to the other end of the second curve 182 than in the maximum open position in Figure 2A, so that the pin 25 is also arranged at this point. The projection 13 on the drive lever 12, which can actuate at least one, here two, dampers 21 at the end of the drive lever 12 opposite the holding element 17, is visible in Figure 3A.
[0058] When the pin 25 moves into the maximum closed position, the damper 21, in particular the damper housing 23, pivots on the axis 47. As a result, the central latch 24, which is inserted into the tunnel 28, and thus the axis 42, are arranged in the maximum closed position within the openings 16a and 16b, radially offset from their position in Figures 2A to 2D on the housing 11. Optionally, the damper can be designed to be self-extending.
[0059] 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 reaching the maximum closing position.
[0060] Figures 4A and B show two sectional views of Figure 3A, i.e., the state of the door fitting 10 from Figures 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 pivotally mounted on the pin 26 on the axis 47 and which has the tunnel 28 with the inserted bolt 24. The damper slide 22 can be pivoted on the pin 25 about the lateral axis 43.
[0061] The steering element 19 is mounted on the housing 11 by means of a pin 37 so as to be pivotable 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 about the axis 45 and thus preload the drive lever 12 towards 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.
[0062] Pivoting the drive lever 12 leads to a relaxation and / or an extension 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 bolt 24 moves in the radial direction perpendicular to the axis 42.
[0063] Figures 5A to 5C illustrate such a movement of the drive lever 12 into a maximum opening position. Pins 15 and 25 move within curves 181 and 182, respectively, with curve 181 defining the maximum opening position of the drive lever 12, and pivoting arm 14 pivoting about the outer axis 44 by movement of pin 25, which is pivotally mounted on the lateral axis 43.
[0064] Figures 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 wasted position, so that the pressure roller 36 is arranged at one end of the curved guide 122. The energy accumulator 31 has an extended state in Figure 6A compared to Figure 4A.
[0065] 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, via a movement initiated by the pivoting steering element 19, can emerge from a rigid positioning in the maximum closed position on the curved guide 122 and 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 closed 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.
[0066] Figures 7A to 7C show the area of the main axis 41 in several enlarged views for a maximum closed position of the drive lever 12. The pin 15 is offset from the maximum opening position, and the pivot arms 14 are pivoted. The pin 15 rests against the pivot contour 141 of the pivot arms 14.
[0067] Figures 8A to 8C show in detail how the pivot arms 14 are pivotally connected to the damper slide 22 by means of the pin 25. In particular, Figure 8C shows how the pin 15, which is arranged on the drive lever 12 according to the other figures, can actuate the pivot arm 14 and pivot it about the outer axis 44 when the drive lever 12 moves into a maximum closed position, 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 closed position. In this exemplary 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.
[0068] Figure 9 shows an exploded view of the components of the door fitting 10.
[0069] Figures 10A to 10C show the latch 24 from the previous figures. The pin has at least one, here two, notches 241 and, in particular on a side opposite the notches 241, a projection 242.
[0070] Figures 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.
[0071] Figures 12A to 12C show 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 axially displacing it 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. When the latch 24 is pushed further into the tunnel 28, the projection 242 on the latch 24 enters the recess 282 in the damper housing 23 in the region 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 less far inserted position of the bolt 24, the damper piston 27 is released, so that it contributes to braking the drive lever 12. For example, in Figures 8C and 12B, it is clearly visible that the damper housing 23 has a special contour in the area of the receptacles 29, which the damper slide 22 also has as a negative. If 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, even though only one damper is guided in the slide. The deactivated damper 21 is located completely in the damper housing 23.To ensure that the damper slide 22 and the damper housing 23 fit together 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 beveled edges act as an inlet guide and an anti-twist device.
[0072] Figures 13A and 13B show a further embodiment of a piece of furniture 1 according to the invention, which comprises two door leaves 4, 5, wherein the door leaf 4 is supported in a maximum closed position by means of several retaining elements on side walls 3 of a furniture body 2. A retaining element 17 of a door fitting 10 according to the invention is mounted on the door leaf 4 and is movable via a drive lever 12. The door leaf 4 is pivotally connected to the door leaf 5, which is guided in a guide rail 9. Optionally, a retaining device can be mounted on the door leaf 5 and a top panel 7 of the furniture 1.
