Abstract

A work vehicle that facilitates attachment of an air conditioner main body, the work vehicle including an air conditioner main body arrangement part for arranging therein an air conditioner main body. The air conditioner main body arrangement part is provided in a ceiling part of a cabin covering a driver unit of the work vehicle so that the air conditioner main body arrangement part protrudes rearward from a pair of left and right rear strut pieces of the cabin. The air conditioner main body arrangement part includes a main body support member protruding rearward, which is provided to an upper rear beam piece laterally bridged between upper end portions of the pair of left and right rear strut pieces. The main body support member has support rigidity to support the air conditioner main body from below so that the air conditioner main body is mounted thereon from above.

First claim

The invention claimed is:

1. A work vehicle, wherein:
an air conditioner main body arrangement part for arranging therein an air conditioner main body is provided in a ceiling part of a cabin covering a driver unit, in such a manner that the air conditioner main body arrangement part protrudes rearward from a pair of left and right rear strut pieces of the cabin;
the air conditioner main body arrangement part includes a main body support member protruding rearward, which is provided to an upper rear beam piece laterally bridged between upper end portions of the pair of left and right rear strut pieces;
the main body support member has support rigidity to support the air conditioner main body from below;
the main body support member enables attachment of the air conditioner main body from above;
the main body support member includes a horizontal protruding surface portion which is integrally formed by rigid thin sheet metal in such a manner as to horizontally protrude, and a rising surface portion which rises upward from a rear end edge portion of the horizontal protruding surface portion; and
the rising surface portion has a plurality of attachment stays horizontally protruding inward, thereby enabling attachment of the air conditioner main body from above via the plurality of stays in a bridging manner.

2. The work vehicle according to claim 1 , wherein:
the air conditioner main body includes an arrangement, in a main body casing, comprising at least devices for generating cooled air and warmed air;
side walls of the main body casing have a plurality of outwardly protruding attachment pieces facing the attachment stays; and
each of the attachment pieces is overlapped in an up-down direction with a corresponding one of the attachment stays, and an attachment bolt is penetrated and screwed in the overlapping portion, in the up-down direction, thereby enabling attachment of the air conditioner main body from above to the attachment stays in a bridging manner, via the attachment pieces.

3. The work vehicle according to claim 2 , wherein a space is formed between the main body support member and the air conditioner main body attached to the main body support member in a bridging manner, via the attachment stays and attachment pieces.

4. An apparatus comprising:
a cabin frame defining a cabin of a work vehicle having a front end and a rear end, the cabin frame comprising a left front strut, a right front strut, a left rear strut, a right rear strut, the cabin frame having a front portion corresponding to the front end and a rear portion corresponding to the rear end; and
an air conditioner main body arrangement part coupled to the cabin frame, the air conditioner main body arrangement part comprising:
a rear beam piece extending from the left rear strut to the right rear strut;
a main body support member configured to support a bottom surface of an air conditioner main body, the main body support member extending from the rear beam toward the rear end of the work vehicle; and
an attachment stay extending from a top portion of the main body support member toward an interior of the cabin, the attachment stay configured to be coupled to a top surface of the air conditioner main body.

5. The apparatus according to claim 4 , wherein:
the cabin frame further comprising an upper left beam extending in a rear direction from the left front strut to the left rear strut; and
the air conditioner main body is disposed within a cavity associated with a ceiling of the cabin frame.

6. The apparatus according to claim 5 , wherein the main body support member comprises:
a horizontal surface portion defining a front end and a rear end, the horizontal surface portion extending horizontally in the rear direction from the front end to the rear end; and
a rising surface portion extending vertically from the rear end of the horizontal surface portion.

7. The apparatus according to claim 6 , wherein air conditioner main body arrangement part comprises:
multiple attachment stays that include the attachment stay, each of the multiple attachment stays extend from the rising surface portion toward an interior of the cabin.

8. The apparatus according to claim 7 , further comprising:
a main body casing of the air conditioner main body and comprising one or more attachment pieces, each of the one or more attachment pieces extending from the main body casing toward the main body support member.

9. The apparatus according to claim 8 , wherein the multiple attachment stays and the one or more attachment piece define at least one bridge that is interposed between the main body support member and the air conditioner main body.

10. The apparatus according to claim 9 , wherein:
at least one of the one or more attachment pieces defines a first opening; and
at least one of the one or more attachment stay defines a second opening.

11. The apparatus according to claim 10 , wherein a bolt extends through the first opening and the second opening.

12. An apparatus comprising:
an air conditioner main body arrangement part coupled to a cabin frame of a work vehicle having a front end and a rear end opposite the front end, the air conditioner main body arrangement part comprising:
a main body support member coupled to a left rear strut and a right rear strut of the cabin frame and extending away from the cabin toward the rear end of the work vehicle, the main body support member comprising:
a horizontal surface portion defining a first end and a second end, the first end positioned intermediate the left rear strut and the right rear strut of the cabin frame, and the second end extends away from the first end toward the rear end of the work vehicle; and
a rising surface portion extending vertically from the second end of the horizontal surface portion.

13. The apparatus according to claim 12 , wherein the main body support member is configured to support a bottom portion of the air conditioner main body.

14. The apparatus according to claim 13 , wherein the main body support member is configured to be coupled to a top portion of the air conditioner main body via an attachment member coupled the rising surface portion.

15. The apparatus according to claim 14 , wherein:
the rising surface portion comprises one or more attachment stays protruding toward the front end of the work vehicle; and
a plurality of attachment stays are configured to attach a top surface of an air conditioner main body to the main body support member.

16. The apparatus according to claim 15 , further comprising:
the air conditioner main body comprising a main body casing configured to surround an air conditioner main body, the main body casing comprising:
a lower case;
an upper case; and
one or more attachment pieces configured to be coupled to the plurality of attachment stays.

17. The apparatus according to claim 16 , wherein:
the main body support member defines a cavity; and
the main body casing is disposed within the cavity defined by the main body support member.

18. The apparatus according to claim 17 , wherein:
the main body casing is positioned apart from the main body support member to define a gap between the main body casing and the main body support member; and
the plurality of attachment stays extend between the main body support member to the main body casing to span the gap.
