Abstract

An ejection device includes an ejection element for spreading apart a folding door from a closed position. At least two door wings are arranged in a common closing plane, towards an open position, and the at least two door wings form an angle different from 180° relative to each other. The ejection element can be acted upon by an energy storage member to be manually loaded by an operator, and the ejection device includes a locking device for releasably locking the ejection element against the force of the loaded energy storage member. The locking device can be unlocked by applying pressure to the folding door. The ejection device includes a movably-mounted loading element for loading the energy storage member by folding together the folding door. The ejection element and the loading element are spatially separated constructional units, and the ejection element is a pivotally mounted ejection lever.
