Abstract

An operating device for a height-adjustable seatpost tube including a lifting magnet. The lifting magnet has a magnetic core surrounded by a coil. The magnetic core cooperates with an actuating device of a lifting device, the lifting device being a pneumatic lifting device for height-adjustment of the seatpost tube and thus for heigh-adjustment of the seat, for example.

First claim

The invention claimed is:

1. An operating device for a height-adjustable seatpost tube comprising:
an outer seatpost tube;
an inner seatpost tube, such that the inner seatpost tube is at least partially located within the outer seatpost tube;
a lifting magnet located in a housing, the lifting magnet having a coil surrounding a magnetic core such that the housing is disposed at and operatively connected to a bottom end of the outer seatpost tube;
an electrical switching device connected to the coil;
an actuating device cooperating with the magnetic core for actuation of a lifting device of the height-adjustable seatpost tube;
a preloading device having a first end and a second end, the first end acting on a front side of the magnetic core; and
an adjustment device located at the second end of the preloading device,
wherein the lifting device is selected from a pneumatic device, a hydraulic device, and/or a spring device, and
wherein the inner seatpost tube can be adjusted by a user by actuation of the lifting device.

2. The operating device according to claim 1 , wherein the actuating device is connected with the front side of the magnetic core.

3. The operating device according to claim 2 , wherein the front side of the magnetic core cooperating with the actuating device is opposite a rear side cooperating with the preloading device.

4. The operating device according to claim 2 , wherein the actuating device rests on the magnetic core.

5. The operating device according to claim 1 , wherein the actuating device is bar-shaped.

6. The operating device according to claim 5 , wherein the actuating device extends in a longitudinal direction of the magnetic core.

7. The operating device according to claim 1 , wherein a stop for the magnetic core connects in a stopped position in an actuating position.

8. The operating device according to claim 1 , wherein the lifting magnet is disposed at least partially inside the housing.

9. The operating device according to claim 8 , wherein a stop is connected to the housing.

10. The operating device according to claim 9 , wherein the stop is integrally formed with the housing.

11. The operating device according to claim 1 , wherein the preloading device is a preloading spring.

12. The operating device according to claim 11 , wherein the preloading device rests on the magnetic core.

13. The operating device according to claim 11 , wherein the preloading device is connected to an adjusting device for adjusting a preloading force.

14. The operating device according to claim 1 , wherein a force required to operate the lifting device is applied partially by the preloading device and partially by the lifting magnet.
