Operator's cab for a work machine
First Claim
1. An operator'"'"'s cab for a work machine, comprising:
- a ceiling structure;
a floor structure;
a first and a second vertical support bar extending between the ceiling structure and the floor structure;
an operator'"'"'s station in the operator'"'"'s cab configured to position an operator in a driving position, a central region of the operator'"'"'s station defining an index axis extending substantially perpendicular to a seating area of the operator'"'"'s station;
a first index angle defined between a longitudinal axis of the work machine and a line extending from the index axis to the first vertical support bar; and
a second index angle defined between the longitudinal axis and a line extending from the index axis to the second vertical support bar,wherein the first vertical support bar is disposed such that the first index angle is less than about 30 degrees, and wherein the second vertical support bar is disposed such that the second index angle is greater than about 70 degrees, and wherein the difference between the first index angle and the second index angle defines a viewing angle, the viewing angle being unobstructed by a vertical support bar.

Abstract
An operator'"'"'s cab for a work machine includes a ceiling structure and a floor structure. An operator'"'"'s station is disposed between the ceiling structure and the floor structure, and is configured to position an operator in a driving position. First and second vertical support bars extend from the ceiling structure to the floor structure. The first and second vertical support bars are disposed forwardly of the operator'"'"'s station and are spaced a substantially equal distance from a longitudinal axis of the work machine. Third and fourth vertical support bars also extend from the ceiling structure to the floor structure. The third and fourth vertical support bars are spaced a substantially equal distance from the longitudinal axis. The distance from the first and second vertical support bars to the longitudinal axis is less than the distance from the third and fourth vertical support bars to the longitudinal axis.
