Description

The present invention relates to a piece of furniture with a furniture body on which a flap is held via two flap fittings, according to claim 1.

the EP 1 705 328 B1 discloses an opening and closing device for a flap door, in which the flap is held on two rotatable arms. The two arms are coupled to one another via toothed areas so that the flap is pivoted by the two arms when it is opened. The disadvantage of this flap fitting is that the flap covers an opening area of the furniture body in the folded position and the user has to apply comparatively large forces in the vertical direction for an opening movement.

the EP 2 138 658 B1 discloses a flap fitting for a furniture flap, in which the furniture flap can be pivoted by an actuating arm and a control lever. The swivel arm is mounted about a fixed axis of rotation, while the control lever is articulated via a pivot axis that can be moved on a bearing part. As a result, the pivoting movement of the furniture flap can be guided in the desired path of movement, but it is precisely in the initial area of the opening movement that sluggishness can occur.

DE 100 47 978 discloses a hinge for striking a furniture door on an upright furniture wall.

DE 1 800 624 discloses a hinge for a hood.

It is therefore the object of the present invention to create a piece of furniture in which an optimized sequence of movements for opening and closing the flap is obtained.

This object is achieved with a piece of furniture with the features of claim 1.

In the case of the furniture according to the invention, each flap fitting comprises a support lever which, in the event of a rotary movement, drives a first gearwheel, which directly or indirectly drives a second gear, the control lever being rotatably mounted on the second gear at a distance from the axis of rotation of the second gear. As a result, the movement of the support lever and the control lever are coupled to one another via the gear wheels, so that the support lever and the control lever are mechanically guided over the entire range of movement of the flap. Through the coupling via the gearwheels, a smooth movement can be set via an energy storage device, which largely compensates for the weight forces.

An energy storage device is therefore preferably provided which biases the flap in a closed position in the closing direction and biases the flap in an opening area in the opening direction. The user then only has to overcome the closing forces of the energy storage device for an opening movement and move the flap up to an opening area in which the energy storage device then automatically biases and moves the flap in the opening direction. The opening area can, for example, begin between 20% to 50% of the entire range of motion of the flap when viewed from the closed position, so that only a slight opening movement is required by the user and the flap can then be moved further in the opening direction via the energy storage device.

The energy store is preferably coupled to at least one gearwheel via a rotatably mounted control disk. In this case, a curved guide can be formed in the control disk, on which a holder connected to the energy storage device is guided. The energy store can have one or more springs, in particular tension springs, which are tensioned in the housing of the flap fitting.

For a compact structure, a gear made up of several gear wheels can be provided between two side walls of the housing. The use of gears makes it possible to adjust the forces for moving the flap, and in particular the axis of rotation of the control lever can be changed in order to ensure a harmonious sequence of movements.

In order to avoid a hard impact, at least one damper can be provided, by means of which an opening and / or closing movement of the flap is braked before the end position is reached.

For simple assembly, a connection can be mounted on the flap, on which the axis of rotation for the support lever and the axis of rotation for the control lever are provided, so that the distance between the two axes of rotation is predetermined by the connection. A damper for braking an opening movement of the flap can also be provided at the connection. The damper can also take on a holding function in order to ensure that the flap is fixed in a certain opening area when the user lets go of the flap.

The connection can be designed in one or more parts.

In the case of the swivel fitting, the flap is preferably moved away from the flap fitting with an upper section during an opening movement, that is to say forwards towards the user. As a result, the flap stands up into the room, so that an opening area on the furniture body can be fully used, in particular if the lower area of the flap is arranged in the maximum opening position in the area of the top of the cabinet. The flap can be designed as a dimensionally stable front panel, but also as a pivoting flap that consists of two or more parts and is folded up during the opening movement.

A piece of furniture 1 comprises a furniture body 2, for example for an upper cabinet in a kitchen, in which in Figure 1 the back wall has been omitted. The furniture body 2 is closed on a front side by a pivotably mounted flap 3. To guide the flap 3, a flap fitting 4, which has a housing 5, is mounted on opposite side walls of the furniture body 2. Each flap fitting 4 comprises a support lever 6 and a control lever 7, which are connected to the flap 3 via a connection 9. The two connections 9 of the opposite flap fittings 4 are synchronized via a rod 8, so that the flap fittings 4 are moved essentially synchronously when the flap 3 is opened and closed.

In Figure 2 a flap fitting 4 with the flap 3 without a furniture body 2 is shown. The housing 5 of the flap fitting 4 comprises two side walls 50 and 51 which are arranged at a distance from one another via a multiplicity of spacers 52. Other housing shapes can also be used for the housing 5.

In the Figures 3A and 3B the flap 3 is shown in an open position. An upper area of the flap 3 has been pivoted forwards away from the furniture body 2, while a lower area of the flap 3, on which a handle element (not shown) is mounted, has been pivoted essentially vertically upwards. In this respect, the user only has to carry out a slight horizontal movement and essentially a vertical movement when opening and closing the flap 3.

In the Figures 4A and 4B the flap fitting 4 is shown in a closed position. The support lever 6 and the control lever 7 are partially arranged parallel to one another and run essentially in the vertical direction up to the connection 9, which is mounted on the flap 3.

In Figure 5 the flap fitting 4 is shown in a closed position without the side wall 50 of the housing. The support lever 6 is articulated at one end around an axis of rotation 61 on the connection 9 and on the opposite side around an axis of rotation 60 which is provided on the housing 5. A first gearwheel 10 is non-rotatably connected to the support lever 6 about the axis of rotation 60 and meshes with a second gearwheel 11, which is mounted on the housing 5 so as to be rotatable about an axis of rotation 12.

On the second gear 11, spaced from the axis of rotation 12 of the gear 11, an axis of rotation 70 is provided, on which the control lever 7 is rotatably mounted. The control lever 7 is mounted on the opposite end so as to be rotatable about an axis of rotation 71 on the connection 9. The axis of rotation 70 thus moves when the flap 3, which is held on the connection 9, is opened and closed.

In order to partially compensate for the weight of the flap 3 during opening and closing, an energy storage device 20 is provided which comprises three springs 21, in particular tension springs in the illustrated embodiment, which are arranged between a first spring holder 22 and a second spring holder 24. The second spring holder 24 is fixed to the housing 5 via a fastening 25. The spring holder 22 is connected to a movable holder 18 via a rod 23. A receptacle 19 is provided on the holder 18, to which the rod 23 of the energy storage device 20 is fixed, so that the holder 18 is pretensioned by the energy storage device 20. The holder 18 has a guide element 17 which is mounted in a curved guide 16 of a control disk 15. The control disk 15 is rotatably mounted about an axis of rotation 14 which is provided on the housing 5. Furthermore, the control disk 15 is non-rotatably coupled to a third gear 13 which is in engagement with the first gear 10.

Various positioning options for positioning the rod 23 of the energy storage mechanism 20 are formed on the receptacle 19 of the holder 18, so that an optimal pre-setting of the spring action to the weight forces of the flap 3 to be compensated can already be made by selecting a suitable position. Instead of the positioning options, stepless presetting can also be provided, for example in the form of a screw / nut connection, by means of which the position of the rod 23 in relation to the holder 18 can be changed.

The term “gear” is understood to mean turntables with external teeth, the external teeth optionally extending over the entire circumference or only part of the circumference. Alternatively, toothed segments, internal toothings or other components on which teeth are provided for positive engagement with an adjacent toothed wheel can also be used as toothed wheels.

A damper 30 is also provided on the housing 5, which is designed as a linear damper, in particular as a fluid, liquid or air damper, which is held on a fastening element 31 on the housing 5 and comprises a piston-cylinder unit which, when compressed Damping forces generated. On the side facing away from the fastening element 31, a contact surface 32 is provided, for example a contact roller, which can be contacted by an actuating element 33 on the holder 18.

For an opening process, a handle arranged in the lower region of the flap 3 is actuated by a user in order to move the flap 3 forwards and upwards. In Figure 6 the flap 3 is shown in a slightly open position. The energy storage device 20 is tensioned further at the beginning of the opening movement, since the flap 3 is biased in the closing direction in the area of the closed position. After overcoming a dead center, the energy store 20 supports the movement of the flap 3 in the opening direction.

If the flap 3 is moved further in the opening direction, as shown in FIG Figure 7 is shown, pivot both the support lever 6 about the axis of rotation 60 and the control lever 7 about the axis of rotation 70, which is arranged on the rotatable gear 11. From the closed position ( Figure 5 ) to the position in Figure 7 the gear 11 was rotated approximately 90 °, so that the axis of rotation 70 has also shifted. The gears 10 and 11 are in engagement, so that the two support levers 6 and the control lever 7 are coupled to one another both in the area of the housing 5 and at the connection 9. The rotation of the gearwheel 10 also drives the third gearwheel 13, which rotates the control disk 15. By turning the control disk 15, the cam guide 16 is moved, which allows the springs 21 of the energy storage device 20 to contract during an opening movement after the dead center has been exceeded, so that the energy storage device 20 supports the opening process.

The flap 3 is according to Figure 8 moved further in the opening direction, with an upper end of the flap 3 protruding forward and upward. A lower area of the flap moves essentially vertically upwards just before the opening on the furniture body 2.

In Figure 9 the maximum opening position of the flap fitting 4 is shown. The flap 3 is slightly inclined to the horizontal, for example in a range between 10 ° and 20 °, and largely exposes the opening area on the furniture body 2. Before the maximum opening position is reached, the opening movement can be braked, for example by a damper which is arranged in the connection 9. Alternatively or additionally, the damper 30 is provided in the housing 5, which is compressed by the actuating element 33 on the holder 18, as shown in FIG Figure 8 is shown.

For a closing movement, the user pulls the flap 3 downward against the force of the energy accumulator 20 until the flap 3 is again arranged in the closed position shown in FIG.

In the illustrated embodiment, three gears 10, 11 and 13 are arranged in the housing 5. It is also possible to provide a gear with a predetermined translation in the housing 5 in order to adapt the tensioning and unloading of the energy accumulator 20 even more closely to the weight of the flap 3 and other parameters.

In the Figures 1 to 9 a flap fitting 4 is attached to the inside of a side wall of a furniture body 2. In Figure 10 the flap fitting 4 is not integrated on an inside but in a side wall of the furniture body 2. For this purpose, the side wall comprises a plate-shaped core material 80, for example made of a wood material, on which the housing 5 of the flap fitting 4 is arranged adjacent, either over the entire width of the core material 80 or on a recess of the core material 80, which extends over only part of the width of the core material 80 extends. The housing 5 and the core material 80 are covered on the outside by an outer layer 81 and on the inside by an inner layer 82, with the outer layer 81 and inner layer 82 optionally also being structurally identical, for example made of a film or a decorative layer. In the exemplary embodiment shown, the inner layer 82 is fixed to the core material 80 and the housing 5 via fastening points. The housing 5 can be glued to the core material 5 or fasteners connected. By the arrangement of the housing in the side wall of a furniture body, the housing is only visible from one end face when the flap 3 is open when the support lever 6 and the control lever 7 protrude forwards.
