Definitions

  • the present invention relates to an ejection device for a movable furniture part, with an ejection element for ejecting a movable furniture part from a closed position to an open starting position, an energy storage device for biasing the ejection element in the opening direction, a latching mechanism for adjusting the ejection element in the closed position with a tensioned energy storage device, a clamping element which is movable by the movable furniture part from the open starting position in the opening direction for tensioning the energy accumulator, wherein the ejection element is movable by the movable furniture part from the open starting position in the closing direction for tensioning the energy accumulator.
  • the DE 20 2010 009 797 U1 discloses a device for moving a furniture part, in which a force accumulator exerts a force on the furniture part in the opening direction so that it can be moved from a closed position to a first opening position. From this first opening position, when the furniture part moves in the opening direction, a first charging control means can then control the charging mechanism for charging the energy storage device, in order to then be moved further in the opening direction after charging. Furthermore, second charging control means are provided, which charge the charging mechanism when the furniture part moves in the closing direction. This allows the furniture to be moved from the first opening position in both the opening and closing directions in order to be charged.
  • the lever mechanism for implementing the charging mechanism is comparatively complex, and there is also the problem that when charging the energy storage when the movable furniture part moves in the opening direction at the end of charging, an abrupt drop in force occurs when the charged energy storage is locked. This is perceived as unpleasant by the operator.
  • DE 10 2015 106 781 A1 discloses an ejection device for a movable furniture part, which has a compact structure and by means of which a movable furniture part can be evaluated from a closed position to an open position.
  • An energy accumulator of the ejection device can be locked in the tensioned position via a latching mechanism, with the energy accumulator being used via a movable furniture part both when moving into the opening position. as well as in the closing direction.
  • the force for charging the energy storage increases and when the furniture part moves in the opening direction, there is a rather abrupt drop in the forces for tensioning the energy storage.
  • the latching mechanism comprises at least two cam guides, each with a latching receptacle, and a control element with at least two latches, each latch being lockable on one of the two latching receptacles.
  • Such curves are also known as “heart curves”.
  • This “double locking” enables the use of energy accumulators with high forces, so that heavy movable furniture parts in particular can be moved via the ejection device. This means that high spring forces can be used, especially when space is limited, and can be reliably locked in the tensioned position via the locking mechanism.
  • the energy storage can be tensioned via a tensioning element or an ejection element, depending on whether a movable furniture part is moved from an open starting position in the opening direction or in the closing direction. Regardless of the direction of movement, the energy storage is tensioned and rusted using the locking mechanism.
  • Each curve guide preferably has a starting slope adjacent to the locking receptacle and a respective latch can be moved against one of the starting slopes in order to unlock the control element.
  • the control element can be held on the ejection element and can be moved together with it.
  • the clamping element and the ejection element of the ejection device can be linearly guided on a housing. Both are preferably movable in opposite directions.
  • a spring bar with a guide element is provided on the control element, which can be brought into engagement with a projection on the curved guide in order to move the control element along the curved guide.
  • the control element can be reliably moved into the locking position via the guide element and the projection, regardless of whether the ejection element or the tensioning element ensures tensioning of the energy storage device.
  • the control element can be moved into the respective locking receptacle with short switching paths using the latches.
  • the tensioning element is connected to a transmission gear, with which the force for tensioning the energy accumulator can be changed depending on the distance.
  • a change in the force for tensioning the energy accumulator can be brought about via the transmission gear, depending on whether the tensioning element or the ejection element is used to tension the energy accumulator. This means that an abrupt loss of force when the energy storage device is locked or locked in the tensioned position can be almost avoided, especially if the tensioning is carried out by the tensioning element.
  • the transmission gear preferably comprises a rotation part which is coupled to the tensioning element and the ejection element and via which the tensioning element and the ejection element can be moved in opposite directions.
  • the rotating part can comprise a gear or a friction wheel and can be designed to be eccentric in at least some areas in order to enable a flexible translation.
  • the rotating part has two spiral-shaped gears, with a first gear engaging a rack on the ejection element and a second gear engaging a rack on the clamping element. When the rotating part moves, the ejection element and the clamping element are moved in opposite directions via the engagement of the toothed racks.
  • friction wheels and other means of force transmission can also be used.
  • the rotating part can also be formed in one piece, so that both gears are formed integrally with one another.
  • the rotating part is rotatably mounted on a pivotable lever.
  • an axis of rotation of the rotating part can be pivoted via the pivotable lever.
  • the distance between the racks can remain constant, so that the spiral gears are designed in such a way that an engagement point on the two gears has the same distance.
  • a guide for moving the rotating part can also be provided.
  • the ejection element is connected to a rack via a rocker.
  • the rocker can be held on the ejection element in a rotatable or pivotable manner. This allows relative movement between the rack and the ejection element, at least in the rusted position.
  • the rocker can have a control element that can be brought into engagement with a guide on the housing of the ejection device, so that the position of the rocker depends on the position of the ejection element in the housing. By moving the ejection element, the rocker can then be pivoted relative to the ejection element, so that reliable positive guidance is provided.
  • the ejection element is preferably designed in several parts and comprises a rack which is held displaceably between two end positions relative to the ejection element.
  • the rack of the ejection element can also have a contact surface by means of which the control element of the latching mechanism can be moved in a latching receptacle. This allows the control element to be placed in a guided manner into the locking receptacle, which largely avoids a backward movement when rusting on the locking receptacle and can therefore be carried out with little noise.
  • a damper can be provided, in particular a linear damper, by means of which a movement of the ejection element in the opening direction can be braked before the opened starting position is reached.

Abstract

L'invention concerne un dispositif d'éjection (1) conçu pour une partie de meuble mobile (92, 105). Le dispositif d'éjection (1) comprend : un élément d'éjection (3) conçu pour éjecter une partie de meuble mobile (92, 105) d'une position fermée à une position de départ ouverte ; un accumulateur de force (5) conçu pour précontraindre l'élément d'éjection (3) dans la direction d'ouverture ; un mécanisme de verrouillage conçu pour verrouiller l'élément d'éjection (3) dans la position fermée au moyen d'un accumulateur de force serré (5) ; un élément de serrage (4) qui est mobile au moyen de la partie de meuble mobile (92) depuis la position de départ ouverte dans la direction d'ouverture de façon à serrer l'accumulateur de force. L'élément d'éjection (3) est mobile au moyen de la partie de meuble mobile (92, 105) depuis la position de départ ouverte dans la direction de fermeture de façon à serrer l'accumulateur de force (5). Le mécanisme de verrouillage comprend au moins deux guides incurvés (28) comportant au moins un siège de verrou (29). Un élément de commande (10) comportant au moins deux boulons (11) est installé. Chaque boulon (11) peut être verrouillé au niveau de l'un des deux sièges de verrou (29). Le dispositif d'éjection peut donc assurer une fonction de verrouillage de manière fiable même sous des forces de ressort élevées.
