- the control may be moved by moving the movable furniture member into an override position against the force of the force accumulator to unlock the ejector. Since the control is moved, the forces of the energy storage must be overcome here.
- the electromechanical actuator can be powered by a battery. This eliminates the need for cabling.
- a sensor for triggering the electromechanical actuator may be provided, for example on a handle element of a drawer, a sensor for detecting a force on the movable furniture part or a sensor for detecting a movement of the movable furniture part.
- the sensors can also respond to noise, speech, gestures or other signals.
- the sensor may be embodied as a radar sensor, capacitive or inductive sensor, image sensor, camera, magnetic sensor, force sensor or any other sensor known in the art.

- the drive device may comprise at least two ejection devices whose electromechanical actuators can communicate via signals for the simultaneous release of the ejection device. Such communication can be wireless via radio or via signal cable. This makes it possible, in a piece of furniture, such as a drawer, to effect an ejection movement at the same time on the right and left sides, without the two ejection devices having to be mechanically coupled. Signal transmission to other drawers is also possible, so that, for example, a drawer and an inner drawer lying behind it can be ejected in a chronologically controlled sequence.

- FIG 1 9 an ejection device 6 according to the invention is shown, which corresponds to the preceding embodiment example, wherein the housing 1 0 is arranged on a holder 80 which is fixed to the movable furniture part or a furniture body. Further, an attachment 81 is provided on the housing 1 0, on which an electromechanical actuator 82 is held.
- the electromechanical actuator 82 has an outer sleeve 85 and an inner plunger 84 which is movable in the axial direction, for example by means of a powered solenoid or an electric motor.
- a connecting element 83 can be moved via the plunger 84 in order to move the adjusting element 50 of the ejection device 6.
- the movement of the actuating element 50 takes place against the force of the spring 68 to return the actuating element 50 in a starting position.
- the ejection device 6 can also be unlocked via the electromechanical actuator 82.
- FIGS. 21 to 23 The unlocking via the electromechanical actuator 82 is shown in detail in FIGS. 21 to 23.

- the part 23 forms a guide surface, which is oriented obliquely to the effective direction of the two springs 22 of the force accumulator, preferably at an angle between 60 ° to 90 °.
- the effective direction runs in Figure 21 from top to bottom.
- the pin 41 of the control element is held locked by the part 51 of the actuating element 50, wherein the part 51 bears laterally against the pin 41.
- the energy accumulator with the springs 22 pulls down the pin 41 of the control element in FIG. 21, and the counterforce of the detent receptacle is mainly generated by the guide surface on the part 23, while only a smaller force for laterally supporting the pin 41 rests against the part 51 ,

- Moving the part 51 of the locking receptacle up requires only small forces, since the pin 41 of the control element 40 is not moved against the force of the springs 22, but only the lateral locking of the locking receptacle moves through the part 51. As a result, the pin 41 can now be moved along the inclined guide surface of the part 23 into the loop-shaped guide track 17.
- the ejector 6 can be unlocked either via a depression of the drawer in a Kochdrückwolf and moving the control with the pin 41 against the switching element 60, or via the electromechanical actuator 82. It is of course also possible to omit the switching element 60 and to make unlocking of the ejection device 6 only via the electromechanical actuator 82. If the switching element 60 is removed and thus prevents a mechanical triggering, the electromechanical actuator can also fulfill other functions such as a leaning protection. In this example, it is prevented that the ejection device is triggered when the movable furniture part is longer than a predetermined period of time in an overpressure position. It can also be implemented collision protection or opening lock.
- the electromechanical actuator 82 may be connected to a sensor that detects the touch of a handle member or a contact surface to effect unlocking.
- the sensor can also detect forces, for example tensile forces when pulling on the drawer or pressure forces.
- a movement of the drawer or other sensor element can be detected to initiate an unlocking process.
- the drive device comprises two latchable ejection devices, which are formed according to FIGS. 19 to 23. These two ejection devices 6 can then be synchronized, ie when unlocking a latching receptacle on an ejection device and the other ejector is unlocked, the two electromechanical actuators communicate with each other via radio or cable to cause substantially simultaneously such a triggering operation. It is also possible that the two actuators 82 are connected to each other via a sensor by means of radio or cable and thus trigger together.
