The present invention relates to a piece of furniture having a furniture body with an upper floor and a flap, wherein at least one flap fitting is arranged on the upper floor in order to hold the flap movably between a position closing a storage space of the furniture body and an opening position, wherein the flap fitting comprises a housing on which a support arm is rotatably mounted, which includes a retaining element for fixing the flap, and comprises an energy store, by means of which a force can be applied to the support arm, and a damper is provided, by means of which a movement of the support arm in the closing direction can be braked shortly before the closing position is reached.
DE 203 07 958 U1 discloses a furniture fitting for guiding a pivotable flap, which can be mounted on a top side of a furniture body. The furniture fitting includes a support arm for holding the flap and a separate damping element, which is fixed to the upper floor and interacts with a projection on a support arm when the flap is closed. Due to this arrangement, the fitting builds up very high and damping energy is introduced directly into the upper floor, which can guide deformation of the upper floor.
It is therefore the problem to be solved by the present invention to create a piece of furniture which has an improved introduction of damping energy when a flap is moved in the furniture.
This problem is solved with a flap fitting with the features of claim 1.
The furniture according to the invention comprises a furniture body with an upper floor and a flap, at least one flap fitting being arranged on the upper floor in order to hold the flap movably between a position closing a storage space of the furniture body and an opening position, the flap fitting comprising a housing on which a support arm is rotatably mounted, which comprises a retaining element for fixing the flap, and an energy store, by means of which the support arm can be subjected to a force, and a damper is provided, by means of which a movement of the support arm in the closing direction can be braked shortly before the closing position is reached, the damper being movable by means of an actuating element mounted in the housing. The damper can thus be used for closing damping of the flap, whereby the damping energy is optimally introduced into the piece of furniture. The flap fitting can be compactly formed.
To avoid hard impact noise, the support arm can be braked shortly before reaching the closing position when moving in the closing direction.
The support arm is preferably aligned essentially parallel to the upper floor in its longitudinal direction when the flap is in the closed position. This allows the flap fitting to be formed compactly in the vertical height direction in the closing position.
The actuating element is preferably formed as a rotary lever, which is rotatable about an axle on the housing. A curve guide can be formed on the actuating element, along which a roller or a sliding element can be moved to actuate the damper. This allows the force transmission to be optimally adjusted to the position of the flap on the support arm. Instead of being designed as a rotary lever, the actuating element can also be formed by a guide, for example a linear guide.
In a further embodiment, a projection is provided on the support arm, by means of which the actuating element can be moved shortly before reaching the closing position. A roller can be rotatably mounted on the free end of the projection, which acts on the actuating element so that low frictional forces are present during the movement. Alternatively, a sliding surface can also be provided on the projection, which acts on the actuating element. The sliding surface can be an integral part of the projection or arranged as a separate sliding piece on the projection.
To achieve high damping forces, the damper can be formed as a linear damper with a damper housing and a piston rod that can be moved relative to the damper housing, in particular as a fluid damper, whereby the damper is preloaded into an extended position by a spring. The damper can be fixed to the housing of the flap fitting and can be moved directly or indirectly via the actuating element. Advantageously, the linear damper is arranged relatively horizontally aligned in the housing. As a result, the damping energy is better introduced into the upper floor, so that deflection of the upper floor due to the reduction of the damping energy is avoided. Preferably, the damper is arranged in the housing and one direction of action of the damper, which is designed as a linear damper, is aligned essentially parallel to the upper floor when the flap fitting is mounted on the piece of furniture.
The damper and the energy store can counteract the closing damping of the flap, while the weight of the flap supports the closing movement. It is also possible for the damper to dampen the movement of the flap in the opening direction via the actuating element shortly before reaching the opening position.
The damper and the weight of the flap can then counteract the opening movement of the flap by means of opening damping, while the energy store supports the opening movement.
The support arm is preferably articulatedly connected to a drive lever, which is articulatedly connected to a deflection lever, by means of which the actuating element can be operated before reaching the maximum opening position. The deflection lever can be rotatable about an axle on the housing, with the opening damping being effected by the movement of the deflection lever.
The retaining element for fixing the flap is preferably arranged at the free end on the support arm. The retaining element can comprise a latching mechanism for fixing the flap for tool-free assembly.
For a compact design, the actuating element is unactuated in the opening and closing direction at least in a central section of the swivel range of the flap, so that movement of the actuating element is only necessary in a range of movement before an end position of the support arm.
The energy store preferably includes at least one spring, which is formed in particular as a compression spring and is held with one end on a housing and with an opposite end on a spring holder. A pulling element is fixed to the spring holder. This allows the flap fitting to be formed particularly compactly and can provide high forces. For example, one to six springs can be arranged parallel to each other between the housing and the spring holder. The springs can be guided on pins to ensure linear movement. However, other energy stores can also be used, for example with tension springs or other spring elements.
Preferably, the support arm is connected to a drive lever, which in turn is articulated to a deflection lever. Preferably, the articulation of the drive lever is provided in a central portion of the support arm, preferably in a range between 25% and 75% of the length of the support arm.
For improved handling, an opening limiter can be provided between two components that can be moved relative to each other, for example the drive lever and the deflection lever, by means of which the maximum opening position of the support arm can be adjusted. This can prevent the flap from being arranged too high when it is raised to the maximum opening position that would make it difficult for the user to grip. In addition, the maximum opening position can be adjusted depending on the installation position. For this purpose, the opening limiter can be adjusted using an adjustment element, such as a threaded pin. Optionally, a damper, in particular a linear damper, can be provided on the opening limiter, which can be actuated when the support arm is moved in the opening direction shortly before the maximum opening position is reached.
The energy store is preferably connected to the deflection lever via a connection that can be adjusted in position, so that the effect of the energy store can be changed by adjusting the connection. By adjusting the connection, the working stroke of the energy store and the effect of the energy store can be changed depending on the position of the support arm. This allows increased flexibility when adjusting the energy store to adapt to the weight of the flap.
Preferably, the connection is held on an adjustment means by which the position of the connection relative to the deflection lever can be adjusted. This allows the point at which the energy store applies force to be changed, which changes the effective leverage effect when the support arm is moved. The energy store acts on the deflection lever via the connection, so that the effective lever length can be changed via the distance between the axis of rotation and the connection.
The adjustment means for the connection preferably includes a linear guide, although alternatively a curve guide or a pivoting lever can also be provided to change the position of the connection. If a linear guide is inserted, a rotatable spindle can be provided, for example, which can be adjusted by simple means and enables a compact design. Other linear guides can also be used, for example a toothed rack or latching mechanism with different mounting positions.
Preferably, the adjustment means forms a unit with the deflection lever, which is articulated to the drive lever on the one hand and articulated to the housing on the other. As a result, the connection remains essentially adjacent to the housing, as the drive lever covers a greater distance via the support arm. The adjustment means can be fixed to the deflection lever or can be mounted rotatable around the two axes together with the deflection lever.
In a further embodiment, the energy store is coupled to the adjustable connection via a lever. This allows the energy store to be guided essentially linearly, while a connection between the connection and the energy store is established via the lever or a pulling element.
The piece of furniture can be formed as a wall unit in a kitchen, for example. Preferably, the flap is held on several flap fittings, in particular on opposite sides. The flap fitting can be arranged to lie concealed on the upper floor, for example if the side walls are raised at least to the height of the flap fitting. The flap fitting can be attached to the raised side walls and/or to the upper floor.
In a further embodiment, the depth, side, height and/or inclination of the flap can be adjustable. The adjusting device can be provided on the housing of the flap fitting and or on the fastening interface between the retaining element and the flap. Eccentrics, worm gears, slotted holes and/or molded parts with threads or screws can be used here as adjusting means for setting the relative position in a spatial direction of the flap to the piece of furniture.
The invention is explained in more detail below with reference to several embodiments with reference to the accompanying drawings. It is shown in:
A piece of furniture 1 includes a furniture body 2, on which a flap 3 is pivotably held via two flap fittings 10. The piece of furniture 1 can be formed as a wall unit or other piece of cabinet furniture. The flap 3 is essentially plate-shaped and is held pivotable via a support arm 11 of the flap fitting 10, as can be seen in
As shown in

In a central portion of the support arm 11, preferably in a range between 25% and 75% of the length of the support arm 11, there is an axle 44 to which a drive lever 17 is articulated. The drive lever 17 is articulated about an axle 23 in connection with a deflection lever 18. The deflection lever 18 is rotatable about an axle 39 on the housing 12. The support arm 11 is rotatably mounted on the housing 12 about an axle 41.
The flap fitting 10 includes an energy store 30 with at least one spring, in particular a coil spring, which is arranged between a support 35 on the housing 12 and a spring holder 32. The at least one spring or the springs of the energy store 30 are each arranged around a guide pin 31, which can optionally be telescoped and thus ensures axial alignment of the springs of the energy store. The springs of the energy store 30 are loaded in compression.
The spring holder 32 is connected via a pulling element 33, in particular a tension rod, to a pin 61, which forms a hinge axle for a lever 22. The lever 22 is thus articulated on one side to the pulling element 33 and articulated on the opposite side via a further axle 21 to a connection 19 in the shape of a carriage. The carriage includes a threaded bushing for a spindle 20, which is rotatably mounted on the deflection lever 18 or a component connected thereto. The spindle 20 is rotatable via a drive element in order to be able to adjust the connection 19 in the longitudinal direction of the spindle 20.
An adjustment element 24 for adjusting the position of an opening limiter 26, which is rotatable on an insert 25, is arranged on the deflection lever 18 adjacent to the axle 23. The opening limiter 26 can interact with a linear damper 27, which is held in a damper holder 28 on the drive lever 17. Alternatively, the linear damper 27 can also be provided on the deflection lever 18 and the opening limiter 26 on the drive lever 17. Optionally, the linear damper 27 can also be omitted.
A further damper 37 is arranged in the housing 12 and can be actuated via a damper guide 38, in particular by pressing a piston rod into a damper housing, which is preloaded into the extended position by a spring. The damper guide 38 can be moved via an actuating element 40.
A projection 43 with a roller 45 is arranged in a central portion on the support arm 11, which can be pressed against the actuating element 40 for closing damping.
