Central locking device for tool carriage

摘要

The mechanism comprises two drive elements (7,14), each of which runs along a dimension of the tool trolley. One element (7) is horizontal and the other (14) is vertical. Both drive elements are so joined to each other that they must be moved together. For every object to be secured by a locking action, a locking hook (11,12,19,22) is arranged on one of the two drive elements. The drive elements take the form of displaceable bars (8,9,15) connected by a twin-armed lever (10).
