  • the dashed line along the second path between Si and S 2 shows the difference when no braking forces act on the movable furniture part 3 via the driver 12.
  • the movable furniture part would be only slightly faster at the end of the distance S 2 , wherein a decrease in speed is also due to the other friction forces on the pullout guide 5 or other components that act on the movable furniture part 3.
  • FIG. 20 shows a speed-travel diagram for a lightweight movable furniture part 3, in which the same ejection device 6 with the same springs 22 is used.
  • the movable furniture part 3 is accelerated from the overpressure position or, in the case of an alternative unlocking from the closed position, initially in the opening direction until the speed V max is reached and the position shown in FIG. After reaching the first path, a certain braking effect on the driver 12 via frictional forces generated by the ejector, wherein the difference in the end speed at the end of the second distance (S 2 ) is greater than in Figure 19, since the movable furniture part 3 is lighter.
  • a non-braked movable furniture part 3 is shown, while the continuous line between Si and S 2 represents the braking action of the driver 12. Due to the slowing down of the movable furniture part 3, especially with light furniture parts, it can be prevented that they are ejected in the opening direction at too high a speed and thus could strike hard in the maximum opening position.
  • damping force is speed-dependent, that is, the higher the speed of the movable furniture part at the end of the first travel, the higher the damping forces are to more strongly decelerate the ejection speed at higher speeds.

Abstract

Dispositif d'entraînement d'un élément de meuble mobile (3) comprenant un dispositif d'éjection (6) verrouillable qui permet d'éjecter l'élément de meuble mobile (3) dans une direction d'ouverture à partir d'une position de fermeture, au moyen d'un accumulateur d'énergie (22), le dispositif d'éjection (6) étant déverrouillable par une pression de déclenchement de l'élément de meuble mobile (3) dans sa direction de fermeture, au-delà de sa position de fermeture verrouillée, et un dispositif de rappel qui peut être couplé à l'élément de meuble mobile (3) dans une zone de fermeture afin de tirer l'élément de meuble mobile (3) dans la direction de fermeture jusque dans sa position de fermeture. L'accumulateur d'énergie (22) peut être chargé dans une zone de sollicitation située principalement avant la zone de fermeture dans la direction de fermeture. Le dispositif d'éjection (6) comporte un chariot (30) préchargé par l'accumulateur d'énergie (22), un élément de commande (40) étant guidé en déplacement sur le chariot (30), et étant couplé d'une part à l'élément de meuble mobile (3) par l'intermédiaire d'un entraîneur (12) et d'autre part à une coulisse (17) du dispositif d'éjection (6). L'invention concerne en outre un procédé d'ouverture et de fermeture d'un élément de meuble mobile (3).
