Definitions

  • the invention relates to a flap fitting comprising an actuating arm that is pivotably attached to a base element about an actuating axis between an open position and a closed position, a toggle lever mechanism with a first lever and with a second lever, which are pivotably connected to one another about a pivot axis, and an energy store , which applies force to the toggle mechanism.
  • the flap fitting comprises a fastening fitting that is fixedly connected to a flap and a toggle lever mechanism that is pivotably connected to the fastening fitting.
  • the toggle mechanism has a first actuating arm which is pivotably connected at a free end to the fastening fitting, and a drive lever which is pivotably connected at a free end to a base element of the flap fitting, the first actuating arm and the drive lever being pivotable about a pivot axis are connected to each other.
  • the drive lever is pivotably connected to a drive arm which is guided in a link of the base element and is acted upon with force via a tension spring, so that the cover is acted upon with force via the first actuating arm in the direction of an open position.
  • the present invention is based on the object of providing a flap fitting which enables efficient use of installation space and highly variable positioning force curves.
  • a flap fitting comprising an actuating arm that moves around an actuating axis between an open position and a closed position on a Base element is pivotally attached, a toggle lever mechanism with a first lever and with a second lever, which are pivotably connected to one another about a pivot axis, and an energy store.
  • the energy store engages a first articulation point on the first lever, spaced from the pivot axis, and at a second articulation point, spaced from the pivot axis, on the second lever, the first articulation point and the second articulation point being acted upon by the force accumulator towards one another.
  • An adjusting contour arrangement with an adjusting contour and a guide element is arranged between the first lever and the adjusting arm, the guide element being movable along the adjusting contour and wherein the adjusting arm is acted upon with force by the first lever via the adjusting contour arrangement in the direction of rotation about the adjusting axis.
  • the flap fitting according to the invention has the advantage that it requires little installation space and is particularly flat due to the force introduction of the energy storage device into the toggle lever mechanism that is directed towards one another.
  • a highly variable actuating force can be achieved along the actuating contour, which in particular has a high maximum force.
  • the flap fitting can be designed in such a way that the adjusting contour is formed on the first lever and the guide element is arranged on the adjusting arm at a distance from the adjusting axis.
  • the adjusting contour can be arranged between the pivot axis and the first articulation point.
  • the adjusting contour can also be designed in particular as a cam disk section of the first lever.
  • the adjusting contour is formed on the adjusting arm and the guide element is arranged on the first lever.
  • the setting contour can have a course so that along the setting contour the actuating arm is acted upon by the first lever via the guide element in a first section with a force that acts in a positive direction of rotation about the setting axis, and / or with a force in a second section is applied, which acts in a negative direction of rotation about the adjusting axis. It is furthermore also conceivable that the adjusting contour is configured in a third partial section in such a way that the force with which the adjusting arm is acted upon by the first lever via the guide element is in Direction of the adjusting axis acts so that no torque acts on the adjusting arm.
  • the distance between the first articulation point and the pivot axis can be greater than the greatest distance between the positioning contour and the pivot axis. According to the resulting lever ratios, the force acting on the toggle lever mechanism by the energy store is increased, so that the force acting on the actuating arm from the first lever via the guide element is greater than the spring force. High maximum actuating forces can thus be achieved.
  • the ratio of the distance between the first articulation point and the pivot axis and the distance between the setting contour and the swivel axis can also be designed to be variable over the course of the setting contour.
  • the guide element can have a roller which is supported against the positioning contour. By running the roller on the positioning contour, a continuous course of the positioning force acting on the positioning arm can be realized along the positioning contour.
  • the energy store can comprise a flat spring.
  • flat springs are to be understood as meaning springs which are delimited on two sides facing away from one another by flat surfaces which each have an extension in the height and width direction that exceeds the thickness of the spring many times over.
  • the flat spring can be made from a flat material.
  • the flat material can be plate-shaped.
  • the flat material can be a flat piece of material that is equally thick everywhere and is delimited on two sides facing away from each other by a flat surface that is very extensive in relation to the thickness.
  • the flat spring can be resiliently loaded between the base element and the actuating arm in a plane of the flat material.
  • a plane of the flat material should be understood to mean all planes which are parallel to at least one of the flat surfaces arranged on the two sides facing away from one another and which lie between these flat surfaces along the thickness of the flat spring.
  • the flat spring between the base element and the actuating arm can be resiliently loaded perpendicular to a thickness of the flat material.
  • the flat spring can be U-shaped in the plane of the flat material and form a first leg and a second leg, which merge into one another via a deflection section.
  • the first leg can be rotatably attached to the base element with a first end and engage the first articulation point of the toggle mechanism with the first end.
  • the first end can have a convex part-cylindrical outer surface with which the flat spring is held in a sliding manner in contact with a complementarily formed concave part-cylindrical first sliding surface of the base element.
  • the first end of the flat spring can be arranged so as to be non-displaceable relative to the base element in a direction perpendicular to the connection between the first articulation point and the second articulation point.
  • the first end can be rotatably mounted, for example, on a pin firmly connected to the base element, or the first end of the flat spring can engage positively in a recess in the base element.
  • the second leg can engage with a second end on the second articulation point of the toggle mechanism.
  • the second leg can be guided on the base element in a linearly adjustable manner.
  • a flat second sliding surface can be formed on the base element, against which the second end is held in sliding contact.
  • a sliding element can be arranged between the base element and the second end.
  • an angle can always be formed between the open position and the closed position, which angle is oriented in the direction of the second sliding surface and in particular is less than 180 degrees. This can ensure that a resulting torque acts on the flat spring, so that the second end is held in sliding contact against the second sliding surface.
  • the flat spring is therefore always freely and definitely supported in the base element between the open position and the closed position.
  • the toggle lever mechanism can be freely and precisely supported with the first articulation point and the second articulation point between the first end and the second end of the flat spring and the guide element. This results in a compact structure and simple assembly of the flap fitting.
  • the energy storage device can be designed as a flat spring which is S-shaped, W-shaped, wave-shaped or lattice-shaped in the plane of the flat material.
  • the Figures 1 and 2 which are described jointly below, show a piece of furniture 1 with a flap fitting 12 with a flap 6 in a closed position.
  • the furniture 1 comprises a side wall 2, an upper floor 3, a lower floor 4 and a rear wall 5, which together with a in the Figures 1 and 2
  • the second side wall (not shown) delimit an interior space 10 of the furniture 1.
  • the interior 10 of the furniture 1 is accessible via an opening 9.
  • the opening 9 is closed by the flap 6, which is pivotably connected to the top 3 of the furniture 1 by a hinge (not shown) at an upper end.
  • the flap 6 comprises a lower flap element 7 and an upper flap element 8, which are connected to one another approximately in the middle of the flap 6 via a further hinge, not shown.
  • a fitting element 11 is firmly connected to the lower flap element 7.
  • the fitting element 11 serves as a connecting element between the flap 6 and a flap fitting 12.
  • the flap fitting 12 comprises an actuating arm 13, which at one end via a connection arrangement 14 with the fitting element 11 and is connected at an opposite end to a base element 15 of the flap fitting 12 rotatably about an adjusting axis S1.
  • the base element 15 has an extension in each case in the height and width directions which corresponds to a multiple of the thickness of the base element 15.
  • the base element 15 can be connected to the side wall 2 via fastening elements 40.
  • the base element 15 is shown without a closure plate which can be attached to the base element 15 via receiving bores 41.
  • the base element 15 has a recess 16 in which a spring element 21 is received.
  • the spring element 21 is designed as a U-shaped flat spring and comprises a first leg 22 and a second leg 23, which are connected to one another via a deflection section 24.
  • a first end 25 of the first leg 22 is hook-shaped and has a convex, partially cylindrical outer surface 26 which is in contact with a first sliding surface 17 of the base element 15, which is complementary to the outer surface 26.
  • the first sliding surface 17 is formed by a sliding bearing element 42 which is inserted into the base element 15.
  • the first end 25 of the first leg 22 also has a concave, partially cylindrical inner surface 27, which is in contact with a complementarily designed securing section 18 of the base element 15.
  • the first end 25 of the first leg 22 is received between the first sliding surface 17 and the securing section 18, so that the spring element 21 is rotatably mounted at the first end and is axially displaceable relative to the base element 15.
  • the first sliding surface 17 and the securing section 18 of the base element 15 thus act as a rotary bearing for the spring element 21. It is also conceivable that the spring element 21 at the first end 25 of the first leg 22 via an alternative rotary bearing, for example via a roller bearing or bolt element, is mounted opposite the base element 15.
  • a second end 28 of the second leg 23 is hook-shaped and has a convex, partially cylindrical outer surface 29 which is supported in a linearly sliding manner on a second sliding surface 19 of the base element 15.
  • a sliding element 20 is arranged between the outer surface 29 of the second end 28 and the second sliding surface 19 of the base element 15 .
  • the second end 28 of the second leg 23 also has a concave, partially cylindrical inner surface 30 which is in contact with a toggle lever mechanism 31.
  • the toggle lever mechanism 31 comprises a first lever 32 and a second lever 34, which are rotatably connected to one another about a pivot axis S2.
  • the first lever 32 has a first articulation section 43, on which the spring element 21 engages with the concave, partially cylindrical inner surface 27 of the first end 25 at a first articulation point 33.
  • the second lever 34 has a second articulation section 44 on which the spring element 21 engages with the concave, partially cylindrical inner surface 30 of the second end 28 at a second articulation point 35.
  • the spring element 21 engages the toggle lever mechanism 31 via a bolt section of the first lever 32 and / or via a bolt section of the second lever 34.
  • the toggle lever mechanism 31 is inserted into the spring element 21 under pretension, so that the spring force acts on the first articulation point and the second articulation point from the spring element 21 towards one another.
  • the first lever 32 and the second lever 34 are arranged at an angle ⁇ to one another, which is oriented in the direction of the second sliding surface 19 of the base element 15 or opens in this direction.
  • the closed position shown is the angle ⁇ less than 180 °, in the present case approx. 160 °.
  • a force component thus acts on the second end 28 of the spring element 21, which causes the spring element 21 to rotate about the first articulation point 33 in a positive direction of rotation with respect to the pivot axis S2.
  • the positive direction of rotation corresponds to a counterclockwise rotation.
  • the second end 28 comes into contact with the second sliding surface 19 via the sliding element 20 and is supported thereon.
  • the spring element 21 is thus freely and statically determined in the base element 15.
  • the spring force of the spring element 21 is transmitted to the first lever 32 via the second lever 34 on the pivot axis S2, with that on the first lever 32 acting force has a component which is opposite to the opening of the angle ⁇ .
  • this force component acts in such a way that the first lever 32 rotates about the first articulation point 33 in a negative direction of rotation with respect to the pivot axis S2.
  • the negative direction of rotation corresponds to a clockwise rotation.
  • the first lever 32 has an adjusting contour 37 with which the first lever 32 is supported against a guide element 38.
  • the adjusting contour 37 and the guide element 38 are thus elements of an adjusting contour arrangement 36.
  • the adjusting contour 37 is arranged on the first lever 32 between the pivot axis S2 and the first articulation point 33.
  • the guide element 38 has a roller which is rotatably connected to the actuating arm 13 and is guided in a link 39 in the base element 15.
  • the guide element is arranged on the first lever and the adjusting contour is formed on the adjusting arm.
  • the adjusting contour 37 is in the closed position, which is in the Figures 1 and 2 is shown, in contact with the guide element 38 in such a way that the resulting force between the adjusting contour 37 of the first lever 32 and the guide element 38 impresses a positive torque on the actuating arm 13, that is, a torque acting in the positive direction of rotation about the actuating axis S1.
  • the actuating arm 13 is moved in the direction of the closed position. In the present case, the actuating arm 13 is rotated by the positive torque away from the opening 9 of the furniture 1 in the direction of the interior 10 about the actuating axis S1.
  • the distance between the first pivot point 33 and the pivot axis S2 is greater than the distance between the first pivot point 33 and the contact point between the adjusting contour 37 of the first lever 32 and the guide element 38
  • the force acting on the lever 32 is thus increased in accordance with the law of the lever, so that a high maximum actuating force that acts on the actuating arm 13 can be achieved.
  • the closed position is defined by a first stop 45 in the link 39, on which the guide element 38 comes to rest in the closed position, so that the rotation of the actuating arm 13 about the actuating axis S1 is limited.
  • the closed position it is also possible for the closed position to be defined by the flap 6 resting against at least one of the side wall 2, top 3 and bottom 4 elements of the furniture 1.
  • FIG 3 the furniture 1 is shown with the flap fitting 12 according to the invention in an intermediate position between the closed position and the open position.
  • the actuating arm 13 is pivoted about the actuating axis S 1 in the direction of the opening 9 of the furniture in the intermediate position.
  • the guide element 38 has accordingly moved by the same angular amount in the link 39 of the base element 15.
  • the adjusting contour 37 of the first lever 32 is in contact with the guide element 38 such that the resulting force between the adjusting contour 37 of the first lever 32 and the guide element 38 gives the adjusting arm 13 a negative torque, i.e. a torque acting in the negative direction of rotation , around the adjusting axis S1.
  • the actuating arm 13 As a result of the negative torque acting on the actuating arm 13, the actuating arm 13 is moved away from the closed position in the direction of an open position. In the present case, the adjusting arm 13 is rotated away from the interior of the furniture 1 about the adjusting axis S1 by the negative torque. If the actuating arm is thus brought into an intermediate position, for example by lifting the lower flap element, the actuating arm 13 rotates further in the direction of an open position.
  • FIG 4 the furniture 1 is shown with the flap fitting 12 according to the invention in an open position.
  • the actuating arm 13 is pivoted about the actuating axis S 1 in the direction of the opening 9 of the furniture.
  • the guide element 38 has accordingly moved by the same angular amount in the link 39 of the base element 15 and is in contact with a second stop 46 of the link 39.
  • the actuating arm 13 can therefore no longer rotate in the negative direction of rotation.
  • the adjusting contour 37 of the first lever 32 is in contact with the guide element 38 such that the resulting force between the adjusting contour 37 of the first lever 32 and the guide element 38 of the adjusting arm 13 continues to be negative Torque is impressed about the adjusting axis S1, so that the adjusting arm 13 cannot rotate in the direction of a positive torque and remains in the open position.
  • the negative torque acting on the actuating arm 13 in the open position is selected to be greater than a positive torque acting on the actuating arm 13 from the weight of the flap 6.
  • the flap fitting 12 described above can in principle also be used for other configurations of the furniture 1. So it is conceivable that the flap 6 is made in one piece.
  • the connection of the actuating arm 13 to the fitting element 11 by means of the connection arrangement 14 is designed to be displaceable in order to compensate for differences in the pivoting path of the actuating arm 13 around the actuating axis S1 and of the fitting element 11 around the hinge (not shown) between the flap 6 and the top panel 3.
  • the flap 6 is made in one piece and the hinge between the flap 6 and the top 3 is dispensed with.
  • an additional control arm can be provided on the flap fitting 12, which is pivotably connected to the base element 15 and cooperates with the actuating arm 13 as a link mechanism.
  • the flap fitting 12 takes on both the function of a cover plate and the function of a cover hinge.
