Abstract

A cabin system to be mounted on a vehicle body is disclosed. The cabin system includes a driver'"'"'s seat, an air conditioner body for indoor air conditioning disposed downwardly of the drive'"'"'s seat, a plurality of support pillars constituting a cabin framework, a ceiling portion, and a main duct having a hollow tubular construction, the main duct forming therein an air passageway for the indoor air conditioning. The main duct includes, at a lower portion thereof, a duct connecting opening to be connected to the air conditioner body and also includes, at a lateral portion thereof, a support pillar engaging face. The main duct is attached through the support pillar engaging face to one of the support pillars along an indoor side peripheral face of the one support pillar. The support pillar engaging face of the main duct and the indoor side peripheral face of the one support pillar have profiles complementary with each other.

Claims

1. A cabin system to be mounted on a vehicle body, said cabin system comprising:

a driver'"'"'s seat;

an air conditioner body for indoor air conditioning disposed downwardly of the drive'"'"'s seat;

a plurality of support pillars constituting a cabin framework;

a ceiling portion; and

a main duct having a hollow tubular construction, the main duct forming therein an air passageway for the indoor air conditioning;

wherein the main duct includes, at a lower portion thereof, a duct connecting opening to be connected to the air conditioner body and also includes, at a lateral portion thereof, a support pillar engaging face;

the main duct is attached through the support pillar engaging face to one of the support pillars along an indoor side peripheral face of the one support pillar; and

said support pillar engaging face of the main duct and said indoor side peripheral face of the one support pillar have profiles complementary with each other.

2. The cabin system according to claim 1, wherein said profiles allow simultaneous fitting of said support pillar engaging face of the main duct to at least two outer faces of said one pillar.

3. The cabin system according to claim 1, wherein an ambient air introducing opening to said air conditioner body is formed in said ceiling portion and said main duct forms a connecting opening to be connected to the ambient air introducing opening at an upper portion of the main duct.

4. The cabin system according to claim 1, wherein the main duct includes, at an upper portion thereof, an air discharging opening for discharging an amount of conditioned air from the air conditioner body to the inside of the cabin.

5. The cabin system according to claim 1, further comprising:

an air distributing duct vertically extending forwardly of the driver'"'"'s seat;

a relay duct for connecting the air distributing duct to a conditioned air discharging opening of the air conditioner body;

an inspection access opening at a right/left center of a front floor constituting a floor face forwardly of the driver'"'"'s seat; and

an inspection access opening closing plate for closing the inspection access opening, the inspection access opening closing plate being attachable/detachable from inside the cabin;

wherein the relay duct is disposed downwardly of the inspection access opening closing plate so as to be detached to the inside the cabin through the inspection access opening.

6. The cabin system according to claim 5, wherein

said discharging opening of the air conditioner body is open to the forward side, and a lower end connecting opening of said air distributing duct is open to the downward side;

a rear end connecting opening of said relay duct is connectable from the forward side to the discharging opening of the air conditioner body; and

a front end connecting opening of said relay duct is connectable from the lower side to a lower end connecting opening of said air distributing duct, with said rear end side connecting opening being kept connected to said discharging opening of the air conditioner body.

7. The cabin system according to claim 1, wherein

said plurality of support pillars include a pair of right/left front support pillars;

and

a front upper beam joining the upper portions of the pair of right/left front support pillars is formed and arranged such that a bottom face of said front upper beam extends substantially parallel with the line of sight of a driver seated at a driver'"'"'s seat within said cabin framework.

8. The cabin system according to claim 7, wherein said front upper beam is curved in the form of a forwardly convex arch along a plane parallel with the bottom face.

9. The cabin system according to claim 7, wherein an upper front face of each of the front support pillar is inclined rearward by a predetermined angle relative to a vertical plane, such that the upper front face and the line of sight of the driver seated at the driver'"'"'s seat inside the cabin framework intersect substantially perpendicular with each other.

10. The cabin system according to claim 7, wherein a front frame of a skylight window frame is attached to the upper face of the front upper beam;

and the upper face of the front upper beam and the front frame of the skylight window frame together form a rain gutter for draining rainwater to the right/left opposed sides of the front frame.

11. A cabin system to be mounted on a vehicle body, said cabin system comprising:

a driver'"'"'s seat;

an air conditioner body for indoor air conditioning disposed downwardly of the driver'"'"'s seat;

a plurality of support pillars constituting a cabin framework;

a ceiling portion;

an air distributing duct vertically extending forwardly of the driver'"'"'s seat;

a relay duct for connecting the air distributing duct to a conditioned air discharging opening of the air conditioner body;

an inspection access opening defined at a right/left center of a front floor constituting a floor face forwardly of the driver'"'"'s seat;

an inspection access opening closing plate for closing the inspection access opening, the inspection access opening closing plate being attachable/detachable from inside the cabin;

wherein the relay duct is disposed downwardly of the inspection access opening closing plate and the relay duct can be detached toward the inside of the cabin through the inspection access opening.

12. The cabin system according to claim 11, wherein

said discharging opening of the air conditioner body is open to the forward side, and a lower end connecting opening of said air distributing duct is open to the downward side;

a rear end connecting opening of said relay duct is connectable from the forward side to the discharging opening of the air conditioner body; and

a front end connecting opening of said relay duct is connectable from the lower side to a lower end connecting opening of said air distributing duct, with said rear end side connecting opening being kept connected to said discharging opening of the air conditioner body.

13. The cabin system according to claim 11, wherein

at a lower portion of a front face of an air conditioner body accommodating chamber for the air conditioner body, there is provided a duct inserting opening for inserting a rear end connecting opening of said relay duct to the inside of the air conditioner body accommodating chamber;

and

to an upper portion of the front face of said air conditioner body accommodating chamber, there is detachably attached a front cover plate constituting a portion of the front face of the air conditioner body accommodating chamber.

14. The cabin system according to claim 13, wherein an opening which is opened with removal of said front cover plate is continuous with said duct inserting opening.
