Definitions

  • the present invention relates to an ejection mechanism, in particular for movable furniture parts, with a curved guide, along which a driver is movable, wherein the driver is biased by at least one energy storage in one direction and can be latched to the cam guide with tense energy storage in a closed position, and a with the driver at least in the closed position coupled activator, wherein the activator relative to the cam guide or the cam guide is movable relative to the activator, wherein in the closed position of the driver via a relative movement of the activator relative to the cam guide or a relative movement of the cam guide relative to the activator can be unlocked and a pullout guide and a discharge system.
  • the EP 1 845 821 discloses a drawer opening and closing apparatus in which the drawer is held in a closed position by a latching mechanism.
  • the latching mechanism comprises a driver which can be coupled to a running rail, on which a rod is arranged, which is guided in a control cam. To unlock the drawer is pressed against the force of a spring, so that then the rod is released from the locked position in the control cam and can be moved together with the driver and the track rail.
  • the unlocking of the locking mechanism is effected only by a depression of the drawer.
  • the locking is done by a variety of components that can absorb only limited mechanical stress, since they are filigree and damage is to be expected.
  • the driver in the closed position the driver can be unlocked via a relative movement of the activator to the cam guide, wherein the activator and / or the cam guide is movable both in a first direction and an opposite second direction for unlocking the driver.
  • This can take place both by a pulling movement on the movable furniture part as well as by pressing the movable furniture part unlocking.
  • the user thus has the option of how the ejection mechanism is unlocked. If the movable furniture part is fixed to a pullout guide, either the cam guide or the activator can be movable, while the other component is arranged stationary.
  • the relative movement between the cam guide and activator unlocking is effected by appropriate mechanical means. Further, the handling of the ejection mechanism is simple, with the respective components stably formed and the number of components reduced as compared with prior art solutions.
  • the driver from the closed position by the relative movement between the activator and the cam guide is pivotable.
  • the cam guide may be formed as a guide device in which the driver is movable in opposite directions. It is not necessary to provide a loop-shaped guideway with a detent recess, since the latching can take place at a bent end portion of the guideway. By pivoting the driver this can be unlocked from the angled end portion and transferred to the linear section, in which the energy storage provides for an opening movement.
  • the activator has a first abutment surface for unlocking the driver by movement in the first direction and a second abutment surface spaced from the first abutment surface for unlocking the driver by movement in the second direction.
  • the activator can also be integrally formed, wherein from the closed position, regardless of the direction of movement unlocking of the driver can take place.

  • the driver it is possible to form the driver as a hook, wherein the activator on opposite sides of the hook has a contact surface for unlocking the driver.
  • At least one lever which can be moved by the activator and / or the cam guide is provided, by means of which the driver can be unlocked.
  • the driver can be coupled with play with the activator or the activator is also movably mounted, in particular resiliently and / or rotatably mounted to ensure movement to the starting position.
  • a pull-out guide is also provided with a guide rail which can be mounted on a furniture carcass and a movably mounted running rail, which has an ejection mechanism according to the invention.
  • the activator can be adjustably fixed in the direction of movement of the running rail on the running rail. As a result, tolerances can be compensated to tune the position of the activator exactly to the desired closed position.
  • the pullout guide can be designed as a preassembled unit, wherein the cam guide is fixed to the guide rail.
  • an elastic stop is provided to hold the track with the activator in the closed position. The stop then ensures that the activator is positioned in the closed position, so that it does not accidentally unlock when it moves beyond the closed position. Furthermore, a damper may be provided to decelerate the track before reaching the closed position. This elastic stop can be made adjustable in the extension direction.
  • a use of an ejection mechanism according to the invention and a corresponding pullout guide in household appliances such. in ovens, in refrigerators and / or freezers, in warming drawers is also conceivable.

  • the ejection system is designed so that when unlocking the driver of the first ejection mechanism, the driver of the second ejection mechanism is unlocked from the latched closed position.
  • This ensures synchronization, which is necessary especially for wide drawers, since it may happen in an off-center force introduction to the opening of the drawer that only one ejection mechanism is unlocked on a drawer side. If such unilateral unlocking take place, a force in the opening direction is applied to the ejection system on the unlocked driver and the power storage, which then acts on the second driver over the furniture part and the second pullout guide and pulls it from the unlocked position in the opening direction. As a result, incorrect operations can be safely avoided.
  • the activator and / or the pawl for example, perpendicular to the opening direction slidably or pivotally about a pivot point can be performed.

  • the counterforce to the return movement of the movable part can be applied by spring force, by elastic deformation, in particular of subcomponents.
  • the effects described above can also be achieved by a structure according to a Richtgesperres, Druckgesperres or jump gear.
  • the activator or the pawl may, for example, be linearly guided in oblong holes.
  • the activator or pawl can be returned to the home position by gravity or spring loaded.
  • the activator or pawl may alternatively be equipped with moving parts. These pawls or moving parts can be controlled via cam guides, by gravity, by using elastic material or spring force to return to the starting position.
  • the driver preferably has two spring-loaded counter-acting pawls or levers which allow both a force application and a low-force driving over.
  • These pawls have a restoring moment that, for example, by elastic deformation of an underlying element is achieved.
  • This element has two sections, each section being associated with a pawl.
  • An embodiment as a rocker or leaf spring is also conceivable.
  • the pawls can only be overrun with low force in one direction. This functionality is particularly needed when a multiple-acting activator or activators or pawls are used to control various devices.
