Abstract

A drive device includes an ejection element, a housing, and a locking element for the ejection element. The locking element is disposed in or on the housing and is movable relative thereto, and a detent element, which is connected to the ejection element and, in the closed position, abuts the locking element. In the locking position, the locking element can block the path of the detent element in the opening direction. The ejection element can be released both when a movable piece of furniture is subjected to increased pressure from a closed position in the closure direction and when the movable piece of furniture is pulled from the closure position in the opening direction. A detection system detects the position of the movable piece of furniture, and a transmission device transmits the position of the movable piece of furniture detected by the detection system to the locking element.
