Claims

1 . A person hoisting device, which has a frame (10, 1 10, 210), a person support arranged to be moveable in relation to the frame (10, 1 10, 210), the position of which person support in relation to the frame (10, 1 10, 210) can be changed, and moving means for moving the person support from a first location in relation to the frame (10, 1 10, 210) to a second location in relation to the frame (10, 1 10, 210) along a movement path, which second location is at a distance from the first location, which moving means are arranged to move the person support in the direction of the movement path when changing the position of the person support in relation to the frame (10, 1 10, 210), characterized in that it comprises an auxiliary frame (18, 1 18, 218) supported on the frame (10, 1 10, 210) in a moveable manner, and a rocker shaft (20, 120, 220) supported in a rotatable manner on the auxiliary frame (18, 1 18, 218), to which rocker shaft (20, 120, 220) the person support is attached.

2. The person hoisting device according to claim 1 , characterized in that said person support comprises a seat (14, 1 14, 214).

3. The person hoisting device according to claim 1 or 2, characterized in that said person support comprises an armrest (16, 1 16, 216).

4. The person hoisting support according to any of the claims 1 -3, characterized in that the movement path of the person support is substantially straight and the rocker shaft (20, 120, 220) is substantially perpendicular to the direction of the movement path.

5. The person hoisting support according to any of the claims 1 -4, characterized in that the rocker shaft (20, 120, 220) is in a substantially horizontal position, when the person hoisting device is in the use position.

6. The person hoisting support according to any of the claims 1 -5, characterized in that the person support has a width direction and the rocker shaft (20, 120, 220) is beneath the person support substantially in the middle of the person support, when the person hoisting device is in the use position.

7. The person hoisting device according to any of the claims 1-6, characterized in that it further comprises a limiter for limiting the rotation of the rocker shaft (20, 120, 220).

8. The person hoisting device according to any of the claims 1-7, characterized in that it further comprises a locking member for locking the person support in an immobile manner to the auxiliary frame (18, 1 18, 218).

9. The person hoisting device according to any of the claims 1-8, characterized in that said moving means comprise a hydraulic cylinder (22, 122), which is attached by its first end to the frame (10, 1 10, 210) and by its second end to the auxiliary frame (18, 1 18, 218), a hydraulic pump (24, 124) for pumping hydraulic fluid to the hydraulic cylinder (22, 122), and a lever mechanism between the person support and the hydraulic pump for using the hydraulic pump (24, 124) by changing the po-sition of the person support.

10. The person hoisting device according to any of the claims 1 -9, characterized in that said moving means comprise a gear rack (26), which is attached by its first end to the frame (10, 1 10, 210), and at least one elevator arm (28), which has a first end, by which it is attached to the auxiliary frame (218), and a second end, which has a gripping point (30) attaching to the gear rack (26).

1 1 . A method for producing motive power of a person hoisting device, which person hoisting device has a frame (10, 1 10, 210), a person support which is moveable in relation to the frame (10, 1 10, 210), and moving means for moving the person support from a first location in relation to the frame (10, 1 10, 210) to a second loca-tion in relation to the frame (10, 1 10, 210) along a movement path, which second location is at a distance from the first location, the motive power of which moving means is produced by changing the position of the person support in relation to the frame (10, 1 10, 210), characterized in that the person hoisting device comprises an auxiliary frame (18, 1 18, 218) which is moveable in relation to the frame (10, 1 10, 210), a rocker shaft (20, 120, 220) supported in a rotatable manner on the auxiliary frame (18, 1 18, 218), to which rocker shaft (20, 120, 220) the person support is attached, and the motive power of the person hoisting device is produced by tilting the person support.

12. The method according to claim 1 1 , characterized in that said moving means comprise a hydraulic cylinder (22, 122), which is attached by its first end to the frame

(10, 1 10, 210) and by its second end to the auxiliary frame (18, 1 18, 218), and a hydraulic pump (24, 124) for pumping hydraulic fluid to the hydraulic cylinder (22, 122), and the hydraulic pump (24, 124) is used by changing the position of the person support in relation to the frame (10, 1 10, 210).

13. The method according to claim 1 1 or 12, characterized in that the position of the person support is changed by moving the centre of gravity of the person supported on the person support in relation to the person support.
