Abstract

Disclosed embodiments include power machine cabs, cab subassemblies, corresponding power machines such as skids steer loaders, and methods of assembling cabs and power machines. Some exemplary disclosed embodiments include features aiding in the manufacture of the cabs for power machines, features which allow the cabs to be configurable for different customer preferences or needs, and features which allow detection of tampering with the cab such that the power machine can be controlled accordingly.

First claim

What is claimed is:

1. A frame of a cab assembly of a power machine, the frame including:
a main portion configured to have an aperture to provide operator access to the cab assembly from a front of the power machine;
a lower frontal portion providing a space for the operator's feet while the operator is seated in the cab assembly, the lower frontal portion comprising:
a first side having a first side surface with a plurality of substantially parallel arcuate shaped reinforcement ribs formed therein; and
a front having a front surface positioned such that the lower frontal portion of the frame extends below the main portion of the frame.

2. The frame of claim 1 , wherein the plurality of substantially parallel arcuate shaped reinforcement ribs of the first side surface are substantially parallel to an intersection between the first side surface and an adjacent portion of frame of the cab assembly.

3. The frame of claim 1 , wherein the front surface of the front of the lower frontal portion is positioned such that the lower frontal portion is substantially rearward of the front of the main portion of the cab.

4. A cab for a power machine, the cab assembly comprising:
a frame providing a main portion of the cab, an aperture to provide an operator ingress into and egress from a front of the main portion of the cab, and a lower frontal portion of the cab, wherein the frame of the cab is configured to be pivotally attached to a power machine frame at a cab pivot attachment such that the main portion of the cab and the lower frontal portion of the cab pivot together about the cab pivot attachment;
wherein the lower frontal portion of the frame extends below the main portion of the frame and below the aperture, the lower frontal portion of the frame providing a space for the operator's feet while the operator is seated in the cab.

5. The cab of claim 4 , wherein the lower frontal portion comprises:
a first side having a first side surface; and
a front having a front surface.

6. The cab of claim 5 , wherein the front surface of the lower frontal portion is positioned such that the lower frontal portion is substantially rearward of the front of the main portion of the cab.

7. The cab of claim 6 , wherein the first side surface has a plurality of arcuate shaped reinforcement ribs formed therein.

8. The cab of claim 7 , wherein the plurality of arcuate shaped reinforcement ribs of the first side surface are substantially parallel to an intersection between the first side surface and an adjacent portion of frame of the cab assembly.

9. A cab for a power machine, the cab assembly comprising:
a frame providing a main portion of the cab, an aperture to provide an operator ingress into and egress from a front of the main portion of the cab, and a lower frontal portion of the cab, wherein the lower frontal portion comprises a first side having a first side surface and a front having a front surface, and wherein the first side surface has arcuate shaped reinforcement ribs formed therein which are substantially parallel to an intersection between the first side surface and an adjacent portion of the frame of the cab assembly;
wherein the lower frontal portion of the frame extends below the main portion of the frame and below the aperture, the lower frontal portion of the frame providing a space for the operator's feet while the operator is seated in the cab.
