Abstract

A controller assembly includes a base plate, a bracket, and a first controller main body. The base plate includes a through hole and a frame having an upper surface and a lower surface and surrounding the through hole. The bracket has first and second flange portions supported on the upper surface of the frame at positions opposite to each other over the through hole, first and second side portions coupled respectively to the first and second flange portions and passing through the though hole; and a bottom portion coupled to both of the first and second side portions on the side of the lower surface of the frame. The first controller main body is mounted on a bottom portion of the bracket. Accordingly, a controller assembly which can be readily assembled, a cab of a work implement, and a work machine can be obtained.

First claim

The invention claimed is:

1. A controller assembly to be deployed in a cab for a work machine, comprising:
a base plate including a through hole and a frame surrounding said through hole, said frame having an upper surface and a lower surface;
a bracket including first and second flange portions supported on the upper surface of said frame at positions opposite to each other over said through hole, first and second side portions coupled respectively to said first and second flange portions and passing through said through hole, and a bottom portion coupled to both of said first side portion and said second side portion on a side of the lower surface of said frame;
a first controller main body mounted on said bottom portion of said bracket; and
a second controller main body provided on an upper side of said frame,
wherein distal most opposite ends of said first and second flange portions, distal most opposite ends of said first and second side portions, and distal most opposite ends of said bottom portion define openings such that first and second distal most opposite ends of the bracket are open.

2. The controller assembly according to claim 1 , further comprising:
a vibration damping member arranged between said first controller main body and said bracket.

3. A cab for a work machine having an internal space in which an operator's seat to be seated by an operator is arranged, comprising:
a controller assembly according to claim 1 provided in said internal space.

4. The cab for the work machine according to claim 3 , further comprising:
an air conditioner main body portion arranged behind said operator's seat in said internal space,
wherein said base plate of said controller assembly is mounted on the upper portion of said conditioner main body portion.

5. A work machine, comprising a cab for the work machine according to claim 3 .
