Engaging mechanism for hot drink preparation device e.g. coffee preparation device, has gear wheel that is rotated such that passing of thrust element at driving element is enabled during backward movement of thrust element

摘要

The engaging mechanism (2) has a gear wheel (10) that is provided in a first rotational position such that backward movement of a thrust element (3) from an advanced position is prevented. The gear wheel is located in a second rotational position such that an engaging element (18) is moved along reverse direction at the gear wheel. A driving element is connected with gear wheel by feed motion of the thrust element. The gear wheel is rotated such that passing of the thrust element at the driving element is enabled during backward movement of the thrust element.
