Stop motion mechanism for lifting column, has adjustment rod coupled with another rod in telescopically movable manner so that switching transducer element acts on contact element when reaching rod in upper and lower end positions

摘要

The mechanism has a limit switching device with a push rod, which includes multiple adjustment rods (3, 4, 5), that are movable relative to one another in an adjusting direction. The rod (3) is coupled with a lifting element (1), and the rod (3) is coupled with the rod (4) by an actuator in a telescopically movable manner, in such a manner that a switching transducer element (16), which is connected with the rod (5) acts on a contact element, when reaching the rod (3) in an upper end position and a lower end position.
