Lockable and unlockable appliance through external force application

摘要

Two elements are movably mounted. A third element is movably mounted in one of the two elements. A guide groove (4) is contained in or on one of the three elements and is in contact with a guide pin (5) on one of the three elements. A spring (6) is between the first two elements. The third element tensions a spring (7) and causes the pin to move from its original position into part of the guide groove. The guide groove contains three geometric barriers. A thrust piece (14) prevents the spring tension being completely released.
