  • the damper devices allow comfortable handling of the movable element and reduce the noise.
  • Such a damper device for a furniture flap is shown in EP 1 818 491 A2 (Hetal-Werke Franz Hettich GmbH & Co. KG).
  • the damping device comprises a toggle lever arrangement with two articulated levers, which are each hinged at one end to a body-side fitting part and the other end to a furniture flap. When closing the furniture flap presses a pivot arm arranged on the articulated lever against an oil damper and compresses it, whereby the movement of the furniture flap is damped.
  • the described Befest Trental Fernettidettia comprises a four-bar linkage with two pivot arms and a mounting piece which is attached to a front panel and a fastening piece which is fixed to a furniture body.
  • a front end of a pivot arm is formed as a curved cam, which cooperates with a displaceable in a longitudinal guide link part, wherein the link member is in operative connection with a damper.
  • the gate part passes through a curved path control a Dead center, so that the damper can be effective both when closing the front panel and when opening the front panel.
  • the object of the invention is to provide a device belonging to the aforementioned technical field for pivotally holding a wing flap, which comprises a damper device and is compactly constructed and inconspicuous. Furthermore, the object is to provide a damper device as a retrofit, which can be mounted on an existing devices for pivotally holding a wing flap.

  • the pressure damper cooperates on a first side of the pressure damper via the first transmission element with a first of the two pivot arms in the region of a first of the two end positions, and the pressure damper acts on a second side of the pressure damper via the second transmission element with a second of the two pivot arms in the region a second of the two end positions together.
  • Under wing flap is a one- or multi-part element to understand, which selectively opens or closes the opening to a cavity.
  • the cavity can be formed by a box, a cabinet, a carcass, a storage box or any other piece of furniture or housing.
  • the wing flap with respect to the piece of furniture or housing about a substantially horizontal axis upwards or downwards can be pivoted.
  • the linear pressure damper can be designed as a fluid damper, pneumatic damper or as a pressure damper with pure material damping.
  • a fluid damper is used which comprises a cylinder housing and a guided in the cylinder housing, relative to the cylinder housing movable piston rod.
  • first side of the pressure damper and “second side of the pressure damper” refer to the damping axis. This means that the first side or the second side of the pressure damper is either at the axial end of the cylinder housing facing away from the piston rod or at the free axial end of the piston rod.
  • the wing flap is movable by a pivoting movement along a displacement path from a closed position to an open position and back, wherein two end positions limit the adjustment path.
  • the closed position the wing flap obscures the opening of the piece of furniture or the housing.
  • the open position the wing flap is pivoted away from the opening, so that the interior of the piece of furniture or the housing is accessible from the outside.
  • the term "in the closing direction” used in the present description means that the wing flap is moved from the open position to the closed position. Accordingly, "in the opening direction” means that the wing flap is moved from the closed position to the open position.
  • the wing flap in the region of an end position means that the wing flap is located either in a section of the adjustment path before the closed position or in a section of the adjustment path in front of the open position. It is irrelevant how long this section of the adjustment is.

  • the transverse axis runs in the direction of the narrowest outer dimension of the device.
  • the inventive device has a damper device which is compact and can be installed inconspicuously on the device for pivotally holding the wing flap. Due to the compact design of the damper device, the device takes up barely more space than a device without damper device. As a result, the internal volume of the piece of furniture or of the housing to which the wing flap is attached, virtually not reduced. Due to the compact and inconspicuous design of the damper device this is not perceived as disturbing. Furthermore, the damper device according to the invention enables efficient damping of the wing flap without an additional holding arm, which takes up a great deal of space, as in the damper devices known from the prior art.
  • the damper device according to the invention also prevents the pivoting flap in the area of the end positions from coming into contact with the piece of furniture or the housing in the manner of a shock or bouncing against an end position at too high a speed.
  • damage can be avoided and wear and tear of the components can be reduced.
  • the damper device according to the invention can extend the service life of the components in comparison to a device for pivotally holding a wing flap without damper device.
  • noise can be greatly reduced by the damper device when closing or when opening the wing flap.
  • the wing flap can be released in the area of the end positions and does not have to be carefully guided by hand to the end positions. This increases the ease of use for the user.
  • the damper device according to the invention can be retrofitted without further adaptation to an existing device for the pivotable holding of a wing flap, as described in EP 0 736 659 81 B1 (USM). As a result, it is not necessary to replace the entire device for holding the wing flap. This allows a cost-effective retrofitting of a damper device.
  • the resilient means acting on the four-bar linkage for damping the pivoting movement make it possible to relieve the weight of the flap when opening and closing the flap. This increases the ease of use.
  • the resilient means cooperate with the two traction arms of the four-bar linkage.
  • the resilient means comprise a resilient element displaceably guided around an anchoring element with its expandable part.
  • the transmission elements between the pressure damper and the pivot arms are translationally movable relative to each other. This allows a simple and compact construction of the damper device when using a linear pressure damper.
  • the transmission elements are also in the damping axis translationally movable relative to each other. As a result, the force transmitted by the transmission elements force must not be deflected and the linear pressure damper can interact directly with the transmission elements.
  • the transmission elements may also be rotationally movable.
  • the transmission elements are arranged such that they are moved in the damping of the pivotal movement in the region of both end positions against a force generated by the pressure damper against each other.

  • Under clip connection is a latching, detachable connection to understand.
  • the clip connection comprises a first element with a projection or protruding nose and a second element with a shoulder or a recess. When joining, the projection of the first element engages in the recess of the second element. This allows a simple and secure positive connection of the two elements.
  • the nose can be designed either on the hinge frame or on an element of the damper device.
  • the recess is made on the opposite element.
  • the engagement of the clip connection is perceived acoustically as well as haptically.
  • the damper device can also be fastened to the articulated frame with another connection, for example by means of a screwed, riveted or clamped connection.
  • the transmission elements are designed as arms. This allows a simple and effective interaction of the transmission elements or the pressure damper via the transmission elements with the pivot arms of the four-bar linkage.
  • the arms have a longitudinal axis and a transverse axis perpendicular to the longitudinal axis.
  • the length along the longitudinal axis is at least twice as long as the width of the arms along the transverse axis.
  • the arms are arranged such that their longitudinal axis is substantially perpendicular to the damping axis. This allows a particularly efficient operation of the pressure damper over the arms.
  • the transmission elements may be formed, for example, as a circular or square elements.
  • the arms each have a bearing surface which comprises a concave portion which cooperates with the respective pivot arm such that during the movement of the pivot arms in the region of the end positions, the force generated by the pressure damper is continuously transferable to the pivot arms.
  • Concave section means that the arms have a concave shape towards the inside of the longitudinal axis of the arms.
  • the concave portion may be formed on one or more longitudinal sides of the arms. Since the force is continuously transferable to the pivot arms, it is avoided that the damping abruptly starts, changes or suspends. As a result, unwanted jolts or shocks in the area of the end positions can be avoided. This protects the components and allows a smooth movement sequence of the pivoting movement of the wing flap.
  • the region of the pivot arms which cooperates with the concave portion of the support surface of the arms, a round shape.
  • the cooperation of the concave portion with the pivot arm can be further improved, so that the movement of the pivot arms is particularly gently damped.

  • the arms can, for example, have convex formations or even no specially shaped sections.
  • the damper device comprises a damper housing, in which the pressure damper and the transmission elements are mounted movably relative to the damper housing.
  • the damper housing protects the pressure damper and the transmission elements against external influences and thus ensures their function.
  • the damper housing allows the pressure damper with the transmission elements to be assembled as a structural unit as a whole. This simplifies handling and assembly.
  • the damper housing also allows to store the pressure damper and the transmission elements movable relative to the damper housing.
  • the pressure damper and the transmission elements can also be attached directly to the hinge frame without damper housing.

  • the receiving space may be formed in the form of a recess, a recess, a holder or an opening in the transmission element.
  • the receiving space is formed in each case as a recess in the transmission elements, wherein the recess surrounds the cylinder housing of the pressure damper partially positively.
  • the axial boundary of the recess is formed as a stop.
  • a transmission element has a stop for the free end of the piston rod and the other transmission element has a stop for the axial end of the cylinder housing facing away from the piston rod.
  • the pressure damper is received by the transmission elements and the transmission elements can securely interact with the pressure damper.
  • the transmission elements can also have no abutment space for the pressure damper.
  • the pressure damper can cooperate in this case, for example, with the surface of the transmission elements.
  • the transmission elements can be fastened to one another by means of a clip connection.
  • the latching and easily releasable clip connection allows quick installation of the transfer elements without tools.
  • the pressure damper located in the receiving space of the transmission elements can be easily exchanged if necessary.
  • the clip connection can be carried out very compact.
  • the transmission elements are held in the transverse direction positively in one another by the clip connection, but in the longitudinal direction relative to each other displaceable. The clip connection thus enables a secure attachment in the transverse direction as well as simultaneously a guide of the transmission elements in a movement of the transmission elements in the longitudinal direction.
  • the transmission elements can be fastened to one another, for example, with a clamping connection or with a screw connection.
  • the damper housing has a guide, in which the transmission elements are guided by means of entrainment elements.
  • the guide may include, for example, a groove, a backdrop or a guideway.
  • the driving elements of the transmission elements can be designed as pins, knobs or projections. Through the guide, the transmission elements can be moved easily and safely along a certain displacement relative to the damper housing.
  • the guide also ensures that the transmission elements are optimally aligned with respect to the pivot arms, so that the pressure damper can optimally dampen the pivoting movement of the pivot arms.

  • the damper housing may also have no guide. The transmission elements can then be suspended, for example, within the damper housing without guidance.
  • the pressure damper and the transmission elements between the two areas of the end positions are freely movable relative to the damper housing without force. If the pressure damper and the transmission elements are not in the range of the end positions, the transmission elements and the pressure damper received in them can move freely and without the action of an external force and without bias. This prevents that the transmission elements with the pressure damper in the housing unintentionally tense or that the Transmission elements and the pressure damper are blocked in the housing and thereby hinder the pivotal movement of the pivot arms.
  • the pressure damper and the transmission elements can be firmly clamped between the two areas of the end positions or, for example, always be biased by a pivoting arm, so that they are not freely movable.
