Tip lever ring book mechanism

摘要

An adaptor plate (2) has fixture components (3), for positive or locking engagement with the ring mechanism plate (1). Connection and release are performed by placing the ring mechanism plate and the adaptor plate one on the other and their parallel displacement in the closure (4) and opening direction. An outwardly accessible fixture component (10) is arranged movably on the ring mechanism plate. Through its operation a hooking process preventing parallel displacement between the ring mechanism plate and the adaptor plate can be produced or released.
