Abstract

A work machine can include an operator station, an overhead control station, a first display mounting system, a second display mounting system, a first display device, and a second display device. The operator station can include a rotatable seat. The first display mounting system can be connected to the overhead control station. The first display device can be connected to the first display mounting system. The second display mounting system can be connected to the rotatable seat, and the second display device can be connected to the second display mounting system. The first display mounting system can be operable to selectably adjust a position of the first display device relative to the overhead control station, and the second display mounting system can be operable to selectably adjust a position of the second display device relative to the rotatable seat.

First claim

What is claimed is:

1. A work machine comprising:
an operator station is disposed within a cab that is movably connected to the work machine, the operator station comprising a rotatable seat;
an overhead control station;
a first display mounting system fixedly connected to the overhead control station at least at a first end of the first display mounting system and at a second end of the first display mounting system opposite the first end;
a first display device connected to the first display mounting system, the first display device can move, relative to the overhead control station, laterally along a fixed axis from a leftmost position to a rightmost position and is capable of tilting forward and backward about the fixed axis;
a second display mounting system connected to the rotatable seat; and
a second display device connected to the second display mounting system, wherein: the first display mounting system is operable to selectably adjust a position of the first display device relative to the overhead control station; and the second display mounting system is operable to selectably adjust a position of the second display device relative to the rotatable seat.

2. The work machine of claim 1 , wherein the cab is laterally movable between left and right limits on the work machine.

3. The work machine of claim 1 , wherein the first display mounting system comprises means for rotating the first display device relative to the overhead control station about a first axis of rotation.

4. The work machine of claim 3 , wherein the first display mounting system comprises means for rotating the first display device relative to the overhead control station about a second axis of rotation, the second axis of rotation being different than the first axis of rotation, and one of the first axis of rotation or the second axis of rotation corresponding to said fixed axis.

5. The work machine of claim 1 , wherein the second display mounting system comprises means for rotating the second display device relative to the seat about a first axis of rotation.

6. The work machine of claim 5 , wherein the second display mounting system comprises means for rotating the second display device relative to the seat about a second axis of rotation, the second axis of rotation being different than the first axis of rotation.

7. The work machine of claim 6 , wherein the second display mounting system comprises:
a first mount member rotatably connected to the seat; and
a second mount member connected to the second display device and rotatably connected to the first mount member.

8. The work machine of claim 7 , wherein the second mount member comprises means for rotating the second display device about a third axis of rotation, the third axis of rotation being different than the first axis of rotation and the second axis of rotation.

9. A work machine comprising:
an operator seat disposed within and rotatably moveable relative to a cab, the cab is moveable relative to a frame of the work machine;
a first display mount connected to a component of the work machine, the first display mount is in a fixed position relative to the seat and disposed in the cab;
a first display device connected to the first display mount, the first display device can move, relative to the first display mount and the operator seat, laterally along an axis from a leftmost position to a rightmost position within the cab and is capable of tilting forward and backward about the axis;
a second display mount connected to the seat; and
a second display device connected to the second display mount,

wherein:
the first display mount is configured to selectably adjust a position of the first display device relative to the work machine;
the second display mount is configured to selectably adjust a position of the second display device relative to the seat;
the first display mount is further configured to selectably adjust the position of the first display device by also permitting the first display device to rotate about a vertical axis orthogonal to said axis; and
the vertical axis can move laterally along said axis with the first display device.

10. The work machine of claim 9 , wherein the component of the work machine is an overhead control station of the work machine.

11. The work machine of claim 9 , wherein the second display mount is configured to selectably adjust the position of the second display device by permitting the second display device to rotate about a first axis, rotate about a second axis orthogonal to the first axis, and rotate relative to the seat about a third axis.

12. The work machine of claim 9 , wherein the second display mount comprises an arm connected between the second display device and the seat, and wherein the arm is configured to rotate relative to the seat about the third axis.

13. A rotary mixer comprising:
a frame;
a cab moveable relative to the frame;
a first display mounted at an overhead control station through a first mounting system, the overhead control station disposed in the cab, the first display can move, within the cab, laterally along an axis from a leftmost position to a rightmost position and is capable of tilting forward and backward about the axis;
an operator station disposed in the cab comprising:
a seat rotatable relative to the frame; and
a second display mounted to the seat through a second mounting system;
wherein the first mounting system is configured to permit movement of the first display relative to the operator station;
wherein the second mounting system is configured to permit movement of the second display relative to the seat; and
wherein the first mounting system is configured to permit rotational movement of the first display about a vertical axis such that opposite ends of the first display device move by a same amount during the rotational movement about the vertical axis.

14. The rotary mixer of claim 13 , wherein the first mounting system is configured to permit axial movement of the first display along a horizontal axis and rotational movement of the first display about the horizontal axis.

15. The rotary mixer of claim 13 , wherein the second mounting system is configured to permit rotational movement of the second display about a first axis, rotational movement of the second display about a second axis orthogonal to the first axis, and rotational movement of the second display relative to the seat about a third axis.
