Abstract
A device for adjusting parts which can move in relation to each other includes: a driveable threaded hollow spindle with inner and outer threads increasing in opposing directions; an inner spindle cooperating with the inner threads and connected to a first fixing device to secure the device to one of the moveable parts; and a propulsive tube cooperating with the outer threads via an outer nut. The propulsive tube is connected to a second fixing device enabling fixation on one of the parts which can move in relation to each other. The threaded hollow spindle may be mounted in a rotationally fixed and longitudinally displaceable manner on a catch device which can be rotationally driven around the axis of the hollow spindle.
Claims11
Device for adjusting parts which can move in relation to each other, comprising a driveable threaded hollow spindle (1), whose inner and outer threads rise in opposing directions, an inner spindle (2) which interacts with the inner thread of the threaded hollow spindle (1) and which is connected to a first fixing device in order to secure the device to one of the moveable parts, and a propulsive tube (4) which interacts with the outer thread of the threaded hollow spindle (1) via an outer nut (3) and is connected to a second fixing device (6) enabling fixation of the device on another of the parts which can move in relation to each other, where the threaded hollow spindle (1) is mounted in a rotationally fixed and longitudinally displaceable manner on a catch device (7) which can be rotationally driven about the axis of the threaded hollow spindle (1), and where a guard is provided for the thread of the threaded hollow spindle (1) that extends essentially over the length of the same, characterised in that the guard is designed as a telescopic tube (14), one end of which is guided in longitudinally sliding non-rotating fashion on the propulsive tube (4) and the other end of which is mounted in rotating and non-sliding fashion on the threaded hollow spindle (1).
