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 power machine cab, comprising:
a cab frame forming an operator compartment and having a first side wall, a second sidewall, a front, a rear, a bottom and a top, wherein the front of the cab frame includes a lower portion that extends from the first side wall to the second side wall and from the bottom of the cab frame to a top of the lower portion and a cab door opening located between the top of the lower portion and the top of the cab frame;
an operator seat positioned within the cab;
a cab door configured to cover the cab door opening in the front of the cab frame when in a closed position and to be moved between the closed position and an open position overhead of the operator seat; and
a display mounted to the lower portion of the front of the cab frame at a position between the bottom of the cab frame and the cab door opening, between the first side wall and the second side wall of the cab frame and below the cab door when the cab door is in the closed position.

2. The power machine cab of claim 1 , wherein the top of the lower portion of the cab frame comprises a lip, wherein the display is mounted under the lip below the cab door to protect the display and to prevent the display from interfering with operator ingress and egress.

3. The power machine cab of claim 1 , and further comprising a camera, wherein the display is configured to display a video feed from the camera.

4. The power machine cab of claim 3 , wherein the video feed from the camera is a video feed of a cutting edge of a tool attached to the power machine.

5. The power machine of claim 1 , wherein the display is mounted to the lower portion of the front of the cab frame so as to be centered on the lower portion of the front of the cab frame.

6. A power machine cab, comprising:
a cab frame forming an operator compartment and having a first side wall, a second sidewall, a front, a rear, a bottom and a top, wherein the front of the cab frame has an opening formed therein to provide an operator ingress and egress, wherein the front of the cab frame includes a lower portion that extends from the first side wall to the second side wall and from the bottom of the cab frame to a top of the lower portion and the opening is located between the top of the lower portion and the top of the cab frame;
an operator seat positioned within the cab;
a cab door configured to cover the opening in the front of the cab frame when in a closed position and to be moved between the closed position and an open position overhead of the operator seat; and
a display mounted to the lower portion of the front of the cab frame at a position which is between the bottom of the cab frame and the opening, between the first side wall and the second side wall of the cab frame and below the cab door when the cab door is in the closed position.

7. The power machine cab of claim 6 , wherein the top of the lower portion of the cab frame comprises a lip, wherein the display is mounted under the lip below the cab door to protect the display and to prevent the display from interfering with the operator ingress and egress.

8. The power machine of claim 6 , wherein the position of the display which is below the cab door is centered between the operator's knees when the operator is seated in the cab.

9. The power machine of claim 6 , wherein the display is mounted to the lower portion of the front of the cab frame so as to be centered on the lower portion of the front of the cab frame.
