Abstract
The present invention relates to a telescopic column, comprising at least a first and a second telescopic tube, a first static stabilizing device, a second static stabilizing device, and a mobile stabilizing device, wherein the first and the second stabilizing devices are arranged axially separated at a fixed distance from each other, between the first and a second tube. The mobile stabilizing device is arranged in an inner space of the first tube, and the mobile stabilizing device is axially movable in relation to the first and second static stabilizing devices, and in relation to the first tube, during extension and retraction of the telescopic column.
Claims14
A telescopic column,
- comprising at least a first and a second telescopic tube telescopically movable relative to each other, and a driving arrangement extending through the first and the second telescopic tubes
- wherein the telescopic column further comprises:
- a first static stabilizing device;
- a second static stabilizing device;
- and
- a mobile stabilizing device;
- wherein the first and the second stabilizing devices are arranged axially separated at a fixed axial distance from each other, radially between the first and a second tube, the first and second stabilizing devices being in contact with an inner surface of one of the first and second tubes and with an outer surface of the other of the first and second tubes;
- wherein the mobile stabilizing device is arranged in an inner space of the first tube and in contact with an inner surface of the first tube and the driving arrangement, and
- wherein the mobile stabilizing device is axially movable in relation to the first and second static stabilizing devices, and in relation to the first tube and the driving arrangement, during extension and retraction of the telescopic column.
A telescopic column,
- comprising at least a first, a second and a third telescopic tube,
- wherein the column further comprises:
- a first static stabilizing device;
- a second static stabilizing device;
- a third static stabilizing device;
- a fourth static stabilizing device;
- a first mobile stabilizing device;
- and
- a second mobile stabilizing device;
- and
- a driving arrangement;
- wherein the first and the second static stabilizing devices are arranged axially separated at a fixed distance from each other, and between the first and a second tubes;
- wherein the third and fourth static stabilizing devices are arranged axially separated at a fixed distance from each other, and between the second and the third tubes;
- wherein the first mobile stabilizing device is arranged in an inner space of the first tube, and wherein the first mobile stabilizing device is axially movable in relation to the first and second static stabilizing devices, and in relation to the first tube;
- and
- wherein the second mobile stabilizing device is arranged in an inner space of the third tube, and wherein the second mobile stabilizing device is axially movable in relation to the third and fourth static stabilizing devices, and in relation to the third tube.
