The arrangement may be such that the projection nearest to the handle is first to engage the complementary retainer on the sash, that the projection which is adjacent the nearest projection is next to engage the corresponding retainer, and so on. A safety device can be provided to releasably lock the carrier in the other end position.

Abstract: In the case of a drive rod lock, the drive is guided in the region of the faceplate and in that a housing is mounted on the faceplate. Rotatably mounted in the housing is a handle bush and follower for moving the drive rod. This handle bush and follower assembly is pretensioned into a mid-way position and can be pivoted out of this mid-way position in opposite directions of rotation. The handle bush and follower assembly acts on a control element which is guided parallel with the drive rod and in the vicinity of a narrow side of the housing remote from the drive rod. A handle bush and follower restoring spring engages this control element. A two-armed transmission lever extends from the control element to the drive rod and is mounted in the housing between the control element and the drive rod. A clearance exists between the transmission lever and the control element.
