Operator workplace of a construction machine
The invention relates to an operator workplace of a construction machine, especially a milling machine for processing a road surface, comprising a seat with a seating surface, an armrest arranged to the side of the seating surface and comprising an arm supporting surface, and at least one control element arranged on the armrest for controlling at least one machine function. The invention further relates to a construction machine with such an operator workplace.
1. An operator workplace of a construction machine, comprising:
a seat with a seating surface;
an armrest arranged to the side of the seating surface and having an arm supporting surface configured to support an operator's arm; and
at least one control element arranged on the armrest for controlling at least one machine function,
wherein an adjusting device is provided which is arranged in a manner that the armrest is adjustable between a sitting operating position and a standing operating position which in comparison with the sitting operating position is positioned upwardly in the vertical direction, the armrest and the arm supporting surface being arranged such that a position of the operator's arm relative to the arm supporting surface, and also relative to the at least one control element, is maintained as the armrest is adjusted between the sitting operating position and the standing operating position, and
wherein the adjusting device is arranged in a manner that in the standing operating position the armrest is automatically forwardly offset in the horizontal direction in relation to the seating surface relative to the sitting operating position.
2. An operator workplace according to claim 1 , wherein the adjusting device is arranged in a manner that the adjusting movement of the armrest between the sitting operating position and the standing operating position occurs simultaneously with respect to the height and in the horizontal direction.
3. An operator workplace according to claim 1 , wherein the adjusting device is arranged in a manner that the armrest is laterally adjustable.
4. An operator workplace according to claim 1 , wherein the seating surface is arranged to be upwardly foldable about a horizontal axis and that the adjusting device is functionally coupled with the folding function of the seating surface in a manner that the armrest will pivot from the standing operating position to the sitting operating position following the downward folding into the seating surface.
5. An operator workplace according to claim 1 , wherein the adjusting device comprises a pivot gear which is arranged for performing a pivoting movement of the armrest, which movement is disposed in a vertical plane.
6. An operator workplace according to claim 5 , wherein the pivot gear is a four-link gear.
7. An operator workplace according to claim 5 , wherein the pivot gear is a link mechanism, especially a parallel link mechanism.
8. An operator workplace according to claim 5 , wherein a gear member of the pivot gear is formed by a support element of the armrest.
9. An operator workplace according to claim 1 , wherein the adjusting device comprises an arresting apparatus which is arranged in a manner that the armrest can be locked in the sitting operating position and/or standing operating position.
10. An operator workplace according to claim 1 , wherein the adjusting device comprises a drive apparatus.
11. An operator workplace according to claim 7 , wherein the drive apparatus comprises a cylinder/piston unit, especially a gas-operated compression spring.
12. An operator workplace according to claim 10 , wherein the drive apparatus is simultaneously arranged for locking the armrest in the standing operating position and/or sitting operating position.
13. An operator workplace according to claim 10 , wherein the drive apparatus is linked directly to the pivot gear.
14. An operator workplace according to claim 1 , wherein the adjusting device is arranged in a manner that the positioning of the sitting operating position and/or standing operating position is adjustable.
15. An operator workplace according to claim 1 , wherein a triggering lever is arranged on the armrest, the actuation of which triggers the adjustment between the sitting operating position and the standing operating position and vice versa.
16. A construction machine, comprising:
an operator workplace according to claim 1 .
17. A construction machine according to claim 16 , wherein the operator workplace is arranged to be vibration-dampened in relation to a machine frame of the construction machine.
18. A construction machine according to claim 16 , wherein the operator workplace is arranged in a manner that the seat is pivotable about a vertical axis together with the armrest.
19. A construction machine according to claim 16 , wherein the construction machine comprises a milling machine for processing a road surface.
