Locking device for releasably locking two furniture parts that can move relative to one another

A locking device for releasably locking two furniture parts movable relative to one another against a force of an energy storage mechanism, the locking device comprising:

• a heart-shaped locking contour having a heart-shaped depression;
• a locking element movable relative to the heart-shaped locking contour and configured to be arranged in the heart-shaped depression of the heart-shaped locking contour in a locking position, the locking element being movable out of the heart-shaped depression into a release position by a movement out of the locking position into an overpressed position;
• a push-through depression spaced apart from the heart-shaped depression and configured to receive the locking element;
• and
• a blocking contour configured to block a movement of the locking element out of the push-through depression and into the heart-shaped depression,
• wherein the heart-shaped locking contour, the locking element, the push-through depression, and the blocking contour are configured:
• to allow the locking device to be moved from the release position into the locking position, from the locking position into the release position, and from the release position again into the release position without subsequent locking depending on an amount of pressure exerted on at least one of the two furniture parts, and
• during a transition to a less overpressed position of the locking device, guide the locking element past the heart-shaped depression and move the locking element into the release position via the blocking contour.
