<p>The support (1) has a telescopic support column (8) guided in a tube or cylinder profile (4). A spindle rod (11) is guided in the support column via a motion thread and mounted in a rotatable manner at a free end area of a spindle rod projecting out of the support column. A locking unit (25) cooperates with the tube or cylinder profile and the free end area, for securing the spindle rod against axial displacement relative to the tube. Another locking unit cooperates with the tube and the free end area, for blocking a rotation of the spindle rod relative to the tube profile.</p> |
