Abstract

PURPOSE:To protect a work lamp through prevention of exposure thereof, to prevent the occurrence of breakage, and to improve appearance by covering a corner space, formed above the upper ends of front stays on both sides and the front upper member and in front of the front end of the lateral member of a cabin device, with a front cover, and arranging the work lamp at the interior of the space. CONSTITUTION:In a cabin device 1 of a tractor and the like, the upper ends of front stays 9 on both sides of a cabin frame 8 are intercoupled through a front upper member 12. The front end of a lateral upper member 14 is mounted on the rear parts of the upper end surfaces of the front stays 9 on both sides. A corner space 23 formed above the upper ends of the front stays 9 on both sides and the front upper member 12 and in front of the front end of the lateral upper member 14 is covered with a front cover 24. A work lamp 25 is arranged in the front cover 24. This constitution prevents the work lamp 25 from being exposed frontward from the cabin device 1 to protect the work lamp by means of the front cover 24. Thus, the work lamp 25 is prevented from colliding with the branch of a tree to cause breakage and appearance can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work light mounting structure for a cabin device mounted on a traveling vehicle such as a tractor.

[0002]

2. Description of the Related Art A work light of a conventional cabin device is mounted on a front upper member of the cabin device so as to project forward and be exposed.

[0003]

In the above-mentioned prior art, since the work light projects from the cabin device to the front and has nothing to protect the surroundings and is exposed, it may be damaged by hitting a branch of a standing tree or the like. It didn't look good either.
According to the present invention, a corner space is formed in a front upper portion of a cabin frame, a front cover for covering the corner space is provided, and a work lamp is arranged in the front cover, thereby solving the problems of the conventional art. It is an object of the present invention to provide a work light mounting structure for a cabin device.

[0004]

The concrete means for solving the problems in the present invention is to connect the upper ends of the left and right front columns 9 of the cabin frame 8 with the front upper member 12 so that the upper end surfaces of the left and right front columns 9 are connected to each other. Attach the front end of the lateral upper member 14 to the rear part,
The front cover 24 covers the angular space 23 formed above the upper end of the front upper member 12 and above the front upper member 12 and in front of the front end of the lateral upper member 14, and the work lamp 25 is arranged in the front cover 24. ..

[0005]

An angular space 23 is formed above the upper ends of the left and right front columns 9 and above the front upper member 12 and in front of the front end of the lateral upper member 14. When the angular space 23 is covered with the front cover 24 and the work light 25 is arranged inside the front space 24, the work light 25 is not exposed to the front from the cabin device 1, and therefore the work light 25 is not exposed.
Is protected by the front cover 24, is not damaged by hitting a branch of a standing tree, etc., and has a good appearance.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 7, reference numeral 1 denotes a cabin device mounted on a rear upper portion of the tractor 2, which includes a control device 3, a floor seat 4, left and right fenders 5, left and right steps 6, a driver's seat 7, and the like, and is independently assembled. Attached to the tractor 2.

The cabin frame 8 erected from the left and right fenders 5 and the step 6 has a front support column 9 and a rear support column 1 on the left and right.
0 and a middle column 11 between them, the upper ends of the left and right front columns 9 are connected by the front upper member 12, and the upper ends of the left and right rear columns 10 are connected by the rear upper member 13. The upper ends of the middle columns 9, 10 and 11 are connected by a lateral upper member 14 to form a box-shaped frame.

Reference numeral 17 is a windshield having left and right leg glasses 17a, 18 is an upper rear glass, 19 is a low rear glass, 20 is a side glass, 21 is a door, and 22 is a roof portion. The roll rear glass 19 is formed of a half mirror or dark glass, and the working state of the rear working machine can be seen from the inside of the cabin apparatus 1, but the inside cannot be seen from the outside.

In the front part of the roof portion 22, the front end of the lateral upper member 14 is attached to the rear part of the upper end surface of the left and right front support columns 9 and above the upper end surfaces of the left and right front support columns 9 and the upper surface of the front upper member 12. , The angular space 23 in front of the front end of the lateral upper member 14
Are formed. The angular space 23 is covered with a front cover 24, and a work lamp 25 is arranged in the front cover 24.

The front cover 24 is made of metal or reinforced plastic and is fixed to the front upper member 12. Work light 2
The reference numeral 5 is attached to the front cover 24 or the front upper member 12, and serves as a headlight for illuminating the front and left sides of the tractor 2 near the front wheels and also assists the tractor headlamp. The working light 25 does not project from the front surfaces of the front cover 24 and the front upper member 12, and the periphery thereof is the front cover 2
Since it is surrounded by 4, the branches of standing trees will not hit directly.

Similarly to the front portion, the rear end of the roof portion 22 has the rear end of the lateral upper member 14 attached to the front portion of the upper end surface of the left and right rear columns 10, and the upper ends of the left and right rear columns 10 and the rear upper member 13. An angular space 23 is formed on the upper side of the upper side of the upper side of the horizontal member 14 on the rear side of the rear end thereof. The angular space 23 is covered with a rear cover 26, and a rear work lamp 27 is arranged in the rear cover 26.
