• the invention relates to an ejection device for a movable furniture part, comprising at least two components movable relative to one another and at least one energy accumulator which acts between the at least two components.
• the invention further relates to an ejection device for a movable furniture part, comprising at least two levers pivotable relative to one another, at least one energy accumulator which, in a loaded state, applies a force to the at least two levers in the direction of an open pivoted position, and at least one locking device for releasably locking the at least two levers in a closed position against the force of the loaded energy accumulator.
• the invention relates to a piece of furniture having a furniture body and at least one furniture part movable relative to the furniture body.
• Locking devices with heart-shaped locking contours and ejection devices with such locking devices are state of the art known.
• such ejection devices have the problem that the locking device always locks when the ejection device is in the closed position.
• an ejection device is required that does not automatically generate a locking action upon entering the closed position.
• the ejection devices and locking devices from the prior art are not suitable for locking depending on the relative position—for example, of the ejection device—in the closed position, since the locking device locks in any position of the closed position.
• the JP2011-162994 Describes a door frame with a movable furniture part consisting of two panels and an ejection device, wherein a lever of the ejection device is pressed against a guide rail of the door frame via a compression spring arranged centrally on a base in order to spread the movable furniture part from a closed position into an open position.
• a manual closing process of the movable furniture part the lever engages again in the guide rail of the door frame, the movable furniture part moves into the closed position, and the compression spring is thereby subjected to force.
• the ejection device is locked via a locking device.
• the locking device consists of a gripper, which generates a locking action by engaging with a hook.
• the compression spring transmits force to the lever perpendicular to the base and does not allow small opening angles of the panels, particularly without locking the ejection device at small angles between the lever and the base while maintaining the same functionality. Furthermore, the force of the ejection device is transmitted jerkily by the compression spring, resulting in less comfort when using the furniture and a reduced service life of the components involved in the spreading process.
• the objective technical object of the present invention is therefore to provide a locking device, an ejection device with a locking device and a piece of furniture with such an ejection device which are improved compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated and which are characterized in particular in that a locking is selectively dependent on how far the locking device closes.

• the at least one locking element is arranged in the heart cavity and the locking state is established .
• the ejection device has at least one such locking device, wherein the heart-curve-shaped locking contour is arranged on one and the at least one locking element is arranged on the other of the at least two components movable relative to one another.

• the at least one ejection device In the coplanar position, the at least one ejection device is in the closed position, with the locking devices arranged thereon being in the locked position. This inhibits the force of the energy accumulators, and the at least two plates remain stationary in the coplanar position.
