Abstract
A lock includes a locking element and a control element displaceable to-and-fro between a locked and an unlocked position and a control element also rotatable to-and-fro by a drive to axially displace in either direction a locking element or a drive element cooperating with the locking element. The control element encloses the locking element for the drive element and includes two helical inner grooves, bevels or a thread which cooperates with one or two radially extending protrusions of the locking element. Each groove, bevel or thread merges into an end surface located in a plane extending orthogonal to the axis of rotation of the control element and may include an intermediate surface also located in a plane extending perpendicular to the axis of rotation of the control element.
