Abstract

Disclosed are front entry cabs, and power machines with front entry cabs, having a door that is moveable between opened and closed positions and a display oriented in the cab to provide information to the operator both while the door is in the opened and closed positions. In the opened position, the door is positioned within an operator compartment of the cab above the operator seat and below a top of the cab. The display is positioned to not interfere with the door, door linkages, or operator joystick control.

First claim

What is claimed is:

1. A cab for a power machine, the cab comprising:
a cab frame forming an operator compartment and having a first side wall, a second sidewall, a front side, a rear side, and a top;
an operator seat positioned within the operator compartment;
a cab door configured to cover an opening in the front of the cab frame when in a closed position and be moveable between the closed position and an open position above the operator seat;
a camera providing a video feed;
a display mounted to a pillar of the cab frame in a corner between the front and one of the first and second sidewalls at a position interior to the cab, the display positioned in the corner so as to provide visual access to the display by an operator positioned on the operator seat with the cab door in the closed position, the open position overhead of the operator seat, and in a transition position between the open and closed positions;
a display mount mounting the display to the pillar and configured to allow the display to be rotated between a portrait display position and a landscape display position;
wherein the display is configured to automatically switch, in response to the display being rotated between the portrait and landscape display positions, between displaying operational information when in the portrait display position and displaying the video feed from the camera when in the landscape display position.

2. The cab of claim 1 , and further comprising a linkage coupled to the cab frame and to the cab door and configured to define a path of movement for and support the cab door as the cab door moves between the closed position and the open position overhead of the operator seat.

3. The cab of claim 2 , wherein the display is positioned such that neither the cab door nor any links of the linkage obstruct the operator's view of the display as the cab door moves between the closed position and the open position overhead of the operator seat.

4. The cab of claim 3 , wherein the linkage is a four-bar linkage.

5. The cab of claim 3 , wherein in the open position, the cab door is positioned beneath the top of the cab frame.

6. The cab of claim 2 , wherein the operator seat is configured to slide forward and backward, and the cab further comprising a joystick controller positioned forward of the operator seat, wherein the display is mounted to the pillar at a position such that, with the operator seat moved to its forward most position and with the joystick controller raised to its highest position, the display remains a distance above the joystick controller.

7. The cab of claim 6 , wherein the distance is at least six inches.

8. The cab of claim 1 , wherein the video feed from the camera is a video feed of at least a front edge of a tool attached to the power machine.

9. A cab for a power machine, the cab comprising:
a cab frame forming an operator compartment;
a camera providing a video feed;
a display positioned within the operator compartment of the cab, the display having a display mount configured to allow the display to be rotated between a portrait display position and a landscape display position;
wherein the display is configured to automatically switch, in response to the display being rotated between the portrait and landscape display positions, between displaying operational information when in the portrait display position and displaying the video feed from the camera when in the landscape display position.

10. The cab of claim 9 , wherein the video feed from the camera is a video feed of at least a front edge of a tool attached to the power machine.
