Claim:
A lockable ejection device for ejecting a moveable furniture part, comprising: a cardioid-shaped sliding guide track; a control pin moveable in said sliding guide track, said sliding guide track having: a closing portion in which said control pin is to move during closure of the moveable furniture part; a locking portion having a latching depression for holding said control pin in a locking position; and an opening portion in which said control pin is to move during opening of the moveable furniture part; an overload mechanism arranged in said locking portion for releasing said control pin from the locking position upon movement of the moveable furniture part in an opening direction, said overload mechanism including a blocking element subjected to a force and configured to temporarily block said control pin from traveling in an overload passage, said blocking element being configured to at least partially form said latching depression of said locking portion, said overload passage being defined by a passage wall and configured to allow said control pin to pass therethrough during an overload situation and to open into said opening portion, said passage wall being in a fixed spatial relationship with said closing portion and said opening portion, said blocking element being separate from said passage wall and moveable in said overload passage, said blocking element being configured to block a first part of said overload passage in the locking position, and said overload mechanism being configured so that said blocking element is moveable by said control pin during the overload situation in the opening direction against an actuation force of said blocking element and out of a blocking position of blocking the overload passage so that said first part of said overload passage is cleared; and an ejection spring for ejecting the moveable furniture part, said control pin and said overload mechanism being configured such that: when said first part of said overload passage is cleared, said control pin is moveable into a second part of said overload passage; and when said control pin is in said second part of said overload passage, said ejection device is unlocked and the moveable furniture part is ejectable in the opening direction by said ejection spring.
