Definitions

  • the present invention relates to a flap fitting for a piece of furniture according to the preamble of claim 1.
  • the EP 2 138 658 B1 discloses a flap fitting for a furniture flap, in which the furniture flap is pivotably mounted via an actuating arm and a control lever.
  • the furniture flap is pre-tensioned in the closing direction via a tension spring.
  • energy storage devices are required that are designed to absorb high forces in a compact design.
  • loud impact noises are often perceived as annoying by the user.
  • WO 2006/005086 discloses a flap fitting with an actuating mechanism for a flap, in which a spring device with several parallel springs is provided, which pre-tension an actuating part.
  • Other flap fittings show WO 2012/059173 and EP2 238 306 .
  • WO 2012/095091 discloses a rotary actuator with a linear damper surrounded by a spring.
  • At least two springs designed as helical springs are provided in a damper arrangement, in each of which a linear damper with a damper housing and a piston rod that can be moved relative to the damper housing is arranged.
  • the first and second spring holders are designed as dimensionally stable brackets on which the dampers and springs are mounted. At least three springs, for example four springs, are provided to generate high preload forces, for example to compensate for weight forces in a pivoting flap.
  • the springs can be designed as compression or tension springs.
  • the damper arrangement In order to avoid transverse forces caused by the damper arrangement, it is preferably designed symmetrically with regard to the arrangement of the springs to a central plane.
  • a holder for fixing the damper housing is preferably provided on the first spring holder and a holder for fixing the piston rod on the second spring holder.
  • An elastic stop is arranged between the holder and the second spring holder, which comes into contact with the spring holder in an end position either directly or on a component connected to the spring holder. The stop can be fixed either to the second spring holder or to the end of the holder in order to avoid generating annoying impact noises.
  • the spring holders are connected to one another by additional damperless linear guide means, for example a sliding element guided on a rail, which are arranged outside or inside the springs.
  • the damper housing according to the invention has different areas with different diameters in a piston working chamber in which the piston of the damper can be linearly displaced.
  • the flap fitting with a damper arrangement has a housing that can be fixed to a body, a rotatable support lever and a pivotably mounted control lever, wherein the support lever and the control lever can be connected to a flap in an articulated manner via spaced-apart pivot axes.
  • the movement sequence of the flap can be designed comfortably via the damper arrangement, in particular with regard to closing and opening the flap.
  • the damper arrangement preferably brakes a closing movement of the flap before it reaches the closing position.
  • the force accumulator holds the flap in a closing position in the closing direction pre-tensioned and the flap is pre-tensioned in the opening direction in an opening area.
  • the user can then overcome a dead center when opening the flap, and after overcoming the dead center, the flap can be moved in the opening direction with the help of spring force or automatically.
  • the flap is automatically moved in the closing direction and then braked by the dampers.
  • a middle position of the flap which can be before and/or after the dead center position, the flap can also be kept in balance so that it does not perform any closing or opening movement independently in the middle opening area.
  • a spring holder is preferably coupled to the control lever via a curved guide.
  • the curved guide can be actuated via a gear that is driven by the control lever.
  • Gears, pivoting levers or other gear elements can be used as gears.
  • a piece of furniture 1 comprises a furniture body 2, for example for a wall unit in a kitchen, in which Figure 1 the rear wall was omitted.
  • the furniture body 2 is closed by a pivoting 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 when the flap 3 is opened and closed, the flap fittings 4 are moved essentially synchronously.
  • FIG 2 a flap fitting 4 with the flap 3 without the 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 plurality of spacers 52.
  • Other housing shapes can also be used for the housing 5.
  • the flap 3 is shown in an open position.
  • the flap 3 is positioned with an upper area facing 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.
  • the user only has to perform a small horizontal movement and essentially a vertical movement when opening and closing the flap 3.
  • opening movements of the flap 3 can also be realized. These opening movements include, for example, simply folding up or folding up the flap 3.
  • the flap fitting 4 is shown in a closed position.
  • the support lever 6 and the control lever 7 are arranged partially parallel to each other and run essentially in a vertical direction up to the connection 9, which is mounted on the flap 3.
  • FIG. 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 about a rotation axis 61 on the connection 9 and at the opposite side about a rotation axis 60 which is provided on the housing 5.
  • a first gear 10 is connected to the support lever 6 in a rotationally fixed manner about the rotation axis 60 and is in engagement with a second gear 11 which is mounted on the housing 5 so as to be rotatable about a rotation axis 12.
  • a rotation axis 70 is provided on the second gear 11 at a distance from the rotation axis 12 of the gear 11, on which the control lever 7 is rotatably mounted.
  • the control lever 7 is rotatably mounted on the connection 9 at the opposite end about a rotation axis 71.
  • the rotation axis 70 thus moves during an opening and closing process of the flap 3, which is held on the connection 9.
  • connection 9 can be designed in one or more parts.
  • a force accumulator 20 which comprises three springs 21, in particular tension springs in the embodiment shown, 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.
  • a receptacle 19 is provided on the holder 18, to which the rod 23 of the energy accumulator 20 is fixed, so that the holder 18 is preloaded by the energy accumulator 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 coupled in a rotationally fixed manner to a third gear 13 which engages with the first gear 10.
  • Various positioning options for positioning the rod 23 of the energy accumulator 20 are formed on the receptacle 19 of the holder 18, so that the spring effect can be optimally preset to the weight forces of the flap 3 to be compensated for by selecting a suitable position.
  • a continuous pre-adjustment can also be provided, for example in the form of a screw/nut connection, by means of which the position of the rod 23 relative to the holder 18 can be changed.
  • gearwheel refers to rotary disks with external teeth, where the external teeth extend either over the entire circumference or only part of the circumference.
  • tooth segments, internal teeth or other components can be used as gearwheels, on which teeth are provided for positive engagement with an adjacent gearwheel.
  • 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 generates damping forces when compressed.
  • a contact surface 32 is provided, for example a contact roller, which can be contacted by an actuating element 33 on the holder 18.
  • a handle arranged in the lower area of the flap 3 is operated by a user to move the flap 3 forward and upward.
  • the flap 3 is shown in a slightly open position.
  • the energy accumulator 20 is further tensioned at the beginning of the opening movement, since the flap 3 is pre-tensioned in the closing direction in the area of the closing position. After overcoming a dead point, the energy accumulator 20 supports the movement of the flap 3 in the opening direction.
  • both the support lever 6 pivots about the rotation axis 60 and the control lever 7 pivots about the rotation axis 70, which is arranged on the rotatable gear 11.
  • the gear 11 was rotated by approximately 90°, so that the axis of rotation 70 was 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 gear 10 also drives the third gear 13, which rotates the control disk 15.
  • Turning the control disk 15 moves the cam guide 16, which, after the dead center has been exceeded, enables the springs 21 of the energy accumulator 20 to contract during an opening movement, so that the energy accumulator 20 supports the opening process.
  • Flap 3 is according to Figure 8 further in the opening direction, with an upper end of the flap 3 protruding forwards and upwards. A lower region of the flap moves essentially vertically upwards just before the opening on the furniture body 2.
  • FIG 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.
  • the opening movement can be slowed down, for example by a damper arranged in the connection 9.
  • the damper 30 is provided in the housing 5, which is compressed by the actuating element 33 on the holder 18, as shown in Figure 8 is shown.
  • three gears 10, 11 and 13 are arranged in the housing 5. It is also possible to provide a gear with a predetermined gear ratio 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.
  • the damper arrangement 40 comprises three springs 21 which are designed as helical springs and are tensioned between the first spring holder 22 and the second spring holder 24.
  • the springs 21 are designed as tension springs and have an eyelet at the end which is suspended from pins 26 on the spring holders 22 and 24. Other mechanisms for fastening the springs 21 can also be used.
  • the use of compression springs instead of tension springs is also possible.
  • the two spring holders 22 and 24 are designed in the shape of a bow, with a rod 23 or a joint being provided on the first spring holder 22 for connection to the actuating mechanism.
  • a fastening 25 for fixing to the housing 5 is arranged on the second spring holder 24.
  • the design of the flap fitting 4 is only to be understood as an example.
  • a seven-joint arrangement formed by the support lever 6 and the control lever 7 and other levers can also be used.
  • the support lever 6 and the control lever 7 are thus connected to the flap 3 via the other levers.
  • the axes of rotation of the support lever 6 and the control lever 7 can also be fixed to the base body 5 so that the axis of rotation 70 does not move relative to the base body 5 during the flap movement. This means that the force transmission from the joint arrangement 6, 7 to the damper arrangement 40 can be designed differently.
  • the damper arrangement 40 comprises a damper in each of the two outer springs 21, which is designed as a linear damper and has a damper housing 41 and a piston rod 42.
  • a further coil spring is arranged in the middle spring 21, so that in the damper arrangement in Figures 10A and 10B four springs are actuated when the spring holders 22 and 24 move. It is also possible to use only two or three springs 21 in the damper arrangement 40, or even more than four springs.
  • FIG. 11A and 11B is the damper arrangement of the Figure 10 without springs 21.
  • a sleeve-shaped receptacle 43 is formed on the spring holder 24, into which a cylindrical damper housing 41 is inserted and fixed, for example, by clamping or locking.
  • An elastic stop 44 is arranged at the end of the receptacle 43, for example made of rubber or an elastomer, which dampens loud impact noises between the receptacle 43 and the spring holder 22. Stops 45 are formed for this purpose at the ends of the spring holder 22 which face the receptacles 43.
  • a linearly displaceable piston rod 42 protrudes from each damper housing 41 and has a thickened head section 46 at the end which is fixed to the spring holder 22 in a receptacle.
  • the dampers When the spring holders 22 and 24 are moved relative to one another, the dampers are thus actuated, the dampers being designed as pressure dampers and generating damping forces when the piston rod 42 is pushed into the damper housing 41, while the piston rod 42 is pulled out smoothly. It is also possible to use tension dampers instead of pressure dampers.
  • the linear dampers preferably have a damping fluid, such as oil, in particular silicone oil.
  • the elastic stop 44 is fixed at the end to the holder 43. It is of course also possible to arrange the stop 44 at one end of the bow-shaped spring holder 22 adjacent to the head section 46.
  • a flap fitting 4 is attached to the inside of a side wall of a furniture body 2.
  • the flap fitting 4 is not integrated on an inner side but in a side wall of the furniture body 2.
  • the side wall comprises a plate-shaped core material 80, for example made of a wood material, to which the housing 5 of the flap fitting 4 is arranged adjacent, either over the entire width of the core material 80 or in a recess in the core material 80 that only extends over part of the width of the core material 80.
  • 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, whereby the outer layer 81 and inner layer 82 can optionally also be constructed identically, for example from a film or a decorative layer.
  • 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 connected to fastening means. Due to the arrangement of the housing in the side wall of a furniture body, the housing is only visible from one end when the flap 3 is open and the support lever 6 and the control lever 7 protrude to the front.
