  • This control cam preferably has at least one locking position defining the intermediate position between a minimum tensioned position or a maximum tensioned position of the energy accumulator.
  • top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the housing, energy accumulator, driver, deflection device and the like chosen in the respective figures. These terms are not intended to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.
  • FIG. 1 is denoted by the reference numeral 1 in total designed as an ejection device embodiment of an inventive acceleration device for movable furniture parts.
  • the acceleration device will be described in the following description by way of example with reference to the ejector shown, wherein in this ejection device, a force storage 4 is tensioned during a closing operation of the movable furniture part, for example a displaceable relative to a furniture body push element such as a drawer, a sliding or a swinging door.
  • a force storage 4 is tensioned during a closing operation of the movable furniture part, for example a displaceable relative to a furniture body push element such as a drawer, a sliding or a swinging door.
  • the use of such an acceleration device is also conceivable, for example, as the closing operation of a movable furniture or household appliance supporting feeding device or as the opening and / or closing operation of a sliding door or held on hinged swing-open door.
  • ejector 1 in this case has a housing 2 and a cover 2 closing the housing 2.
