Definitions

  • the present invention relates to an ejection device, in particular for movable paperteiie example, a drawer slide for a drawer, with a latching mechanism by means of a first driver by the force of a first spring in a Schi manposition is latched, the first driver along a guide movable is and can be coupled with an activator connected to a running rail of a pullout guide, wherein the latching mechanism can be unlocked to move the driver together with the activator in the opening direction.
  • EP 1 845 821 discloses a device for opening and closing drawers in which the drawer is held in a closed position by means of a latching mechanism.
  • a driver biased by a spring pushes the running rail in the opening direction, wherein the driver is connected to the latching mechanism and can be decoupled from the running rail.
  • the spring for biasing particularly high spring forces the closing and locking of the drawer for the user can be felt to be difficult, which is also disadvantageous because the high
  • Closing forces must be applied shortly before the closed position. It is therefore an object of the present invention to provide a discharge device, with the larger forces can be provided in the opening direction, but only small forces for unlocking the locking mechanism are required. This object is achieved with an ejection device with the features of claim 1.
  • a second driver in addition to the first driver at least a second driver is provided, which is biased by a second spring in the opening direction and is movable between two end positions along a guide spaced from the closed position in engagement with one with the running rail connected activator to arrive.
  • the forces are provided when opening by two springs, so that particularly high forces i opening direction can be provided.
  • a driver is objected parked or latched by the closed position, so that in the closed position only a small force for unlocking a driver per ejector must be provided. As a result, low forces can be sufficient for unlocking.
  • detent mechanism is to be understood broadly in the present case and also to include a retraction device which pulls the movable furniture part as a self-closing a closed position and holds it there to a stop.Then the user must pull to unlock or tension the self-closing on the movable furniture part to The second driver can then move the movable furniture part in the opening direction and optionally further tension the self-closing mechanism.

  • the second driver can be unlocked in a prestressed position by the activator, whereby the number of components can be reduced by releasing the latch by means of a sliding lock on the running rail
  • a single activator can be arranged on the running rail, which is initially movable together with the first driver in an opening operation, can be decoupled from the first driver and then coupled to the second driver. This activator can then be decoupled when reaching a predetermined opening position of the second driver so that the running rail is free to move without the action of the ejector.
  • the two drivers thus arrive in succession with the activator on the running rail in engagement, wherein in the closing direction also the activator successively first with the second driver and then with the first driver engages and is then locked in the closed position by the second driver.
  • the springs for biasing the first and second driver may have a different spring strength, for example, the second driver may have a greater spring force to accelerate coupled to the track drawer. It is also possible to provide more than two drivers on the ejection device, to move the running rail over a predetermined length in the opening direction. The length of the support of the movement in the opening direction and the spring force can be adjusted freely within wide ranges.

  • Control on which can be latched to a detent recess of a cam guide can be formed, for example, as a wire, which is guided along a groove-shaped cam guide in a housing, with only small forces acting on the control and the cam guide, so that a compact construction is possible.
  • the second carrier is preferably mounted movably along a slot or a groove on a housing.
  • the guide is designed so that in a tensioned end position of the activator can be coupled to the driver and then moved in the direction of travel of the track driver and activator together. Upon reaching an end position, the activator is again decoupled from the driver, for example by an angled or bevelled end portion of the guide, so that the running rail can then be moved freely again.
