DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. Front wheels 5, 5 and rear wheels 6, 6 are provided on the front and rear portions of the vehicle body 7, respectively, and a bonnet 8 with a prime mover is provided at the front portion of the vehicle body 7. Fenders 9 and 9 that cover the upper and inner sides of the wheels 6 and 6 are provided.
[0006]
A cockpit 10 is provided on the vehicle body between the left and right fenders 9, and a floor 11 is provided from below the cockpit 10 to the rear end of the bonnet 8. Front struts 2a and 2a are erected on the front left and right sides of the floor 11, and rear struts 2b and 2b are erected on the rear left and right sides of the floor 11, respectively. Connecting frames 12, 12 are provided between the upper end portions of the, and a roof 13 is placed on these connecting frames 12, 12, thereby forming the cabin 1. Reference numeral 3 denotes a door made of transparent glass. Inside the door 3, an upper frame 15 extending in the front-rear direction, a lower frame 16 in the middle of the door 3 and extending in the front-rear direction, and a rear portion thereof are provided. A door frame 4 having a U-shape in a side view and attached to a vertical frame 30 in the vertical direction connected to each other is attached. As shown in FIG. 1, the door frame 4 is mounted at a position slightly away from the edge of the door 3 toward the inside, and hinges 14 are provided at two corners of the vertical frame 4 of the door frame 4. , 14, the door 3 is pivotally attached to the rear columns 2b, 2b so as to be openable and closable. A door lock device 17 is provided at the front portion of the lower frame 16, and the door 3 can be opened and closed by rotating the knob 32.
[0007]
In this embodiment, the glass of the door 3 is composed of two front and rear glass, and the glass 18 for the latter half is configured to be opened and closed inside and outside by the hinge 33 on the upper side. And the sealing member 20 is attached to the outer periphery part of these glass, and the airtightness in the cabin 1 when the door 3 is closed is maintained. FIG. 3 shows a structure for attaching the door 3 to the door frame 4. A ring-shaped elastic member 22 is fitted into an attachment hole 21 provided in the door 3, and the hole provided in the elastic member 22 and the door frame 4 is provided in the hole provided in the door frame 4. A spring 25 that penetrates the bolt 23 and presses the door 3 in the direction of the door frame 4 is provided between the nut 24 screwed into the bolt 23 and the door frame 4.
[0008]
In the above configuration, a light impact 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 separated from the door frame 4 while the elastic member 22 and the spring 25 are bent. Thus, since a strong impact load is not concentrated on a part of the glass, particularly on the attachment portion of the hinge 14, the glass is not damaged.
[0009]
【The invention's effect】
According to the present invention, in a cabin of a moving vehicle, the door 3 of the cabin 1 is made of frameless transparent glass, and the door 3 is pivotally mounted so as to be openable and closable around two upper and lower hinges 14 and 14. 3, and a frame 16 extending in the front-rear direction at the middle of the upper and lower sides. The front end side of the frame 16 is connected to the door lock device 17, and the rear end side is connected to the lower hinge 14. And the frame 16 is attached to the attachment hole 21 provided in the door 3 in a state of being separated from the inner surface of the glass with the elastic member 22 interposed therebetween, so that the side view of the door 3 of the cabin 1 is enlarged, The impact load at the time of opening and closing the door 3 can be moderately dispersed by the frame 16, and the impact is not directly applied to the glass. Therefore, the glass of the cabin 1 is broken when the door 3 is opened and closed. There is no problem, such as.
Further, the frame 16 is provided inside the glass and along the front-rear direction, and is attached to the attachment hole 21 provided in the door 3 in a state of being separated from the inner surface of the glass through the elastic member 22. Therefore, the driver can hold the frame 16 to open and close the door 3, and the operability when getting on and off is improved.
