Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof structure of a cabin for mounting a roof member of a cabin of a tractor, for example.

[0002]

[Prior Art]

 The cabin of the tractor has front and rear columns, auxiliary columns, etc., and a top frame that is substantially rectangular in plan view is fixed to the upper ends of these, and a roof that includes an air conditioner is installed on the top and bottom of these front and rear columns. Members are attached. In this cabin, the outer surface of the top frame is used as the mounting surface of the curved window glass and the contact surface of the door. Therefore, the outer surface of the front and rear columns (including auxiliary columns, etc.) Some project outwards.

In such a cabin, a bracket is fixed to the inner surface of the top frame, and a roof member mounting portion is formed on this bracket so that the roof member can be mounted from the inside of the cabin.

[0004]

[Problems to be solved by the device]

 In the above-mentioned prior art, the roof member cannot be attached / detached from the outside of the cabin, which makes the work difficult.If a tubular material is used for the front and rear columns, rainwater may enter from the upper end of the tubular mouth. There is such a problem. The present invention provides a cabin roof structure capable of solving the above-mentioned problems of the prior art by fixing a bracket to each upper end surface of the front and rear columns and forming a roof member attachment portion on the bracket. The purpose is to do.

[0005]

[Means for Solving the Problems]

 The concrete means for solving the problem in the present invention is to fix the outer surface side of the top frame 3 to the upper ends of the front and rear columns 2 made of a tubular body, and to fix the roof member 4 to the upper ends of the front and rear columns 2 and the top frame 3. In the roof structure of the cabin in which the brackets are attached, the brackets 5 are fixed to the upper end surfaces of the front and rear columns 2, and the brackets 5 are protruded from the upper ends of the columns 2 along the top frame 3 to attach the roof member. 6 is formed.

[0006]

[Action]

 Brackets 5 are fixed to the upper end surfaces of the front columns 2F and the rear columns 2R, and roof member mounting portions 6 are formed at the portions of the brackets 5 that project along the top frame 3 to form the roof. The member 4 is attached and detached from the outside of the cabin 1. The bracket 5 closes the upper end surface of each of the cylindrical columns 2, and prevents rainwater from entering through the cylindrical opening at the upper end.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 to 3, reference numeral 1 denotes a tractor cabin, a lower part of which is fixed to a vehicle body of a tractor, a front support column 2F, a rear support column 2R, and an auxiliary support column 2H, a ceiling frame 3 fixed to the upper ends of those support columns 2, and a support column 2. And a roof member 4 fixed to the top frame body 3, and the support column 2 and the top frame body 3 are formed of a rectangular tube body.

The top frame 3 has a front member 3A and a substantially U-shaped member 3B, and both ends of the front member 3A are fixed to the inner surfaces of the left and right front columns 2F, and both front ends of the substantially U-shaped member 3B. The surface is fixed to the back surface of the front column 2F. That is, the front column 2F is fixed to the outer surfaces of the front member 3A and the substantially U-shaped member 3B. The front support column 2F has step portions 11A and 11B formed on the inner surface and the back surface thereof, and has a substantially rhombic shape in plan view, and a portion outside the step portions 11A and 11B projects outward from the top frame 3. The windshield 12 is disposed between the left and right inner surface step portions 11A, and the upper portion of the front glass 12 is fixed to the front member 3A. A door 13 is arranged between the rear step portion 11B and the rear support column 2R.

The upper end surface of the front support column 2F is slightly lower than the upper surface of the top frame 3, and a bracket 5F made of a plate material is fixed to the upper end surface by welding or the like, and the upper surface of this bracket 5F is It is flush with the top frame 3. The bracket 5F is fixed to the upper end surface of the front support column 2F, thereby closing the barrel of the front support column 2F. The bracket 5F does not cover the entire surface of the cylinder opening, but is partially opened by the notch 10 so that the cord of the air conditioner 14 arranged in the roof member 4, the drain hose 15 and the like can be inserted.

The bracket 5F does not have the same shape as the upper end surface of the front supporting column 2F, but protrudes from the front supporting column 2F along the top frame 3, and a bolt hole is formed in the protruding portion, so that the roof member mounting portion is formed. It is on the 6th floor. The upper and lower ends of the left and right rear columns 2R are formed in two steps, the lower side face is fixed to the lower face of the U-shaped member 3B, and the upper side face is located on the outer side of the U-shaped member 3B and the bracket 5R is fixed. Like the bracket 5F, the bracket 5R also has a roof member mounting portion 6R that is flush with the top frame 3 and projects rearward along the top frame 3.

The rear support column 2R has its cylindrical opening completely closed by the U-shaped member 3B and the bracket 5R so that rainwater cannot enter at all. A U-shaped member 3B is formed in an arc from the rear support 2R to the auxiliary support 2H, a rear glass 16 is attached, and a hatchback glass 17 is arranged between the left and right auxiliary support 2H. The upper portion of each auxiliary column 2H is fixed to the back surface of the U-shaped member 3B, and the bracket 5H having the roof member mounting portion 6H is fixed to the upper end surface thereof. The bracket 5H completely closes the tube opening of the auxiliary column 2H.

The roof member 4 is usually formed in the middle of an inner roof and an outer roof, the air conditioner device 14 is housed inside the roof member 4, and a bolt hole is formed on the lower surface of the outer periphery of the inner roof. The lower surface of the outer periphery of the inner roof faces the top frame 3 and is attached to the roof member attachment portion 6 of the bracket 5 of each pillar 2 through the bolt 19.

A seal 18 is interposed between the roof member 4 and the bracket 5, and the seal 18 passes outside the notch 10 of the bracket 5F and prevents rainwater from entering from the notch 10. .. It should be noted that the present invention is not limited to the above embodiment, but can be variously modified. For example, the bracket 5 may be fixed to the upper end surface of each pillar 2 and also to the top frame 3 at the same time, or two roof member mounting portions 6 may be formed in one bracket 5, and If the device 14 is not provided, the notch 10 may be eliminated.

[0014]

[Effect of the device]

 According to the present invention described in detail above, the brackets 5 are fixed to the upper end surfaces of the front and rear columns 2, and the brackets 5 are protruded from the upper end surfaces of the columns 2 along the top frame 3 so that the roof member attaching portion 6 is formed. Since the roof member 4 can be attached and detached from the outside of the cabin 1, the work is easy, and even if a tubular material is used for the front and rear columns 2, rainwater will not leak from the top port. Never infiltrate.
