  • Longitudinally adjustable intermediate piece with a unidirectionally acting displacement blocking mechanism
    Patent number: 7905464
    Abstract: The invention relates to a longitudinally adjustable intermediate piece with a first and second longitudinal element. A spindle nut is placed inside the second longitudinal element and rests via one of its two faces on a friction surface of the second longitudinal element while covering a large area or can be brought into contact therewith. However, a friction-reducing axial bearing is provided between the other face of the spindle nut and the second longitudinal element so that the spindle nut can be set in rotation over the thread when applying an axial tractive force to the longitudinal elements and the longitudinal elements can be continuously pulled out of one another. However, the rotation of the spindle nut is blocked when applying an axial compressive force to the longitudinal elements by means of the frictional resistance between the spindle nut and the friction surface thereby preventing the longitudinal elements from being pushed together.
