Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a cabin provided on an agricultural traveling vehicle body such as a tractor.

[0002]

[Prior art]

 Conventionally, in order to expand the field of view of a cabin door, in Japanese Utility Model Laid-Open No. 58-171715, a hinge is directly attached to an unframed glass plate without providing a door frame around the entire glass plate constituting the door. There is a structure in which the door can be opened and closed easily by attaching a handle arm to the inner surface of the glass plate.

[0003]

[Problems to be solved by the device]

 The above conventional cabin has a structure in which the hinge and the door lock device are directly attached to an unframed glass plate, so the supporting load of the glass plate is concentrated on the hinge mounting part of the glass plate, and the door is kept inside the cabin. When opening and closing the door by holding the handle arm to open and close, the pushing and pulling action at the time of opening and closing concentrates on the handle arm attachment part of the glass plate, which may cause distortion or damage to the glass plate. was there.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is directed to a cabin provided on a vehicle body for agricultural use, in which a door frame having a vertical frame and a horizontal frame is provided around a vertical axis on a pillar of the cabin. A frame-shaped transparent glass plate is attached to the outside of the door frame so as to form a door outside the door frame, and the lateral frame is located at least on the side of the cockpit in the cabin. The section is a cabin of an agricultural traveling vehicle characterized by being provided in a state of being separated from the glass plate.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Front and rear wheels 5, 5 and rear wheels 6, 6 are mounted on the front and rear portions of the vehicle body 7, respectively. A hood 8 having a prime mover is provided at the front portion of the vehicle body 7, and rear left and right rear portions are provided at the rear portion of the vehicle body 7. Fenders 9 and 9 are provided to cover the upper and inner sides of the wheels 6 and 6. A pilot seat 10 is provided on the vehicle body between the left and right fenders 9, and a floor 11 is provided from below the pilot seat 10 to the rear end of the hood 8.

Front struts 2a, 2a are erected on both left and right front sides of the floor 11, and rear stanchions 2b, 2b are erected on both left and right rear sides of the floor 11. The connecting frames 12 and 12 are provided between the upper ends of the columns 2a and 2b, and the roof 13 is placed on these connecting frames 12 and 12 to form the cabin 1. Reference numeral 3 is a door made of transparent glass. Inside the door 3, there are an upper frame 15 extending in the front-rear direction and a lower frame 16 located in the middle of the door 3 extending in the front-rear direction. A door frame 4 having a U-shape in a side view, which is composed of a vertical frame 30 in the up-down direction that connects the rear parts of these to each other, is attached. As shown in FIG. 1, the door frame 4 is mounted at a position slightly separated from the edge of the door 3 toward the inner side, and is mounted above and below the vertical frame 4 of the door frame 4. Doors 3 are pivotally attached to the rear columns 2b and 2b via hinges 14 and 14 at the corners of the place so as to be openable and closable. A door lock device 17 is provided at the front of the lower frame 16, and the door 3 can be opened and closed by rotating the knob 32.

In this embodiment, the glass of the door is composed of two front and rear windows, and the glass 18 for the latter half can be opened and closed inside and outside by the hinge 33 on the upper side. A seal member 20 is attached to the outer peripheral edge of these glasses so that the airtightness inside the cabin 1 when the door 3 is closed is maintained. FIG. 3 shows a mounting structure of the door 3 to the door frame 4, in which a ring-shaped elastic member 22 is fitted into a mounting hole 21 provided in the door 3, and the elastic member 22 and the hole provided in the door frame 4. A bolt 23 is inserted through the screw 23, and a spring 25 for pressing the door 3 toward the door frame 4 is provided between the nut 24 screwed to the bolt 23 and the door frame 4. Then, as clearly shown in FIG. 3, the door frame 4 is provided in a state of being separated from the glass surface of the door 3. Therefore, when closing the door after getting into the cabin 1, if you scratch the hand to the frame portion of the lower frame 16 that extends laterally and located on the side of the cockpit, and pull it toward the inside, You can easily close the door while sitting in the cockpit.

In the above structure, a light shock when the door 3 is opened and closed is absorbed by the seal member 20 of the door 3. On the other hand, when the door 3 is strongly closed, a strong impact may be applied to the entire glass. In such a case, the glass is removed from the door frame 4 while bending the elastic member 22 and the spring 25. Since they are separated from each other, a strong impact load is not concentrated on a part of the glass, especially the mounting portion of the hinge 14 and the like, so that the glass is not broken.

[Operation and effect of the device]

 The cabin of the agricultural traveling vehicle of the present invention has a door frame having a vertical frame and a horizontal frame, which is attached to a column of the cabin so as to be rotatable about a vertical axis, and the outside of the door frame. An unframed and transparent glass plate that constitutes the door is attached to the door, and at least the frame portion located laterally of the cockpit in the cabin is provided so as to be separated from the glass plate in the lateral frame. Therefore, while expanding the view of the cabin door, the glass plate of the door can be dispersively supported by the door frame, and a door made of a frameless transparent glass plate can be provided reliably and with good durability. be able to. Also, the door can be opened and closed from inside the cabin by pushing and pulling the frame part located on the side of the cockpit of the lateral frame, so that the door can be easily opened while sitting in the cockpit. In addition to being able to open and close, the pushing and pulling action of the door at the time of opening and closing does not act directly, which also improves the durability of the glass plate.
