ることを目的とする。In the conventional cab for a driver's cab, a rear window which is linear in a plan view is hinged to the rear portion of the cab. Therefore, when the rear window is opened and the hydraulic excavator turns, the air flow inside the cab. However, the glass plate collided with air, and the wind flow could not be smoothly introduced into the cab. In particular, when the left and right glass plates were opened in a double door, the glass plates became a screen facing the wind, and the ventilation of the inside of the cab was blocked. An object of the present invention is to provide a cab structure that can solve the above problems.

能を発揮することができる。In the present invention, since the rear window of the cab is formed as a single curved window which bulges backward, the upper window of the hydraulic excavator is opened by opening the rear window. When swirled in the direction of, the outside air flows into the cab from the opening of the rear window into a substantially arc-shaped airflow in plan view along the curved inner surface of the rear window. Further, in another embodiment of the present invention, the rear window of the cab is divided into a left rear window and a right rear window, and the two left and right rear windows are each formed in a curved shape in plan view which bulges outward. Since the left and right rear windows were hinged to the vertical column frame of the cab rear part, when opening the left and right rear windows together and turning the upper revolving structure, when turning left, from the opening of the right rear window,
Further, when turning right, the outside air flows into the cab through the opening of the left rear window along the curved inner surfaces of the left and right rear windows into a substantially arc-shaped airflow in plan view. Further, in the present invention, since the rear window and the left and right rear windows are opened and closed without protruding from the circle having the maximum turning radius of the upper revolving structure as the radius, when the rear window and the left and right rear windows are opened. Even if the upper swing body is swung, the window can be prevented from colliding with an external obstacle, and the function of the small swing hydraulic excavator can be exerted.

発揮することができる。Next, the cab structure of the first embodiment of the present invention and its operation will be described with reference to FIGS. In the present invention, the rear window 6 hinged to the rear frame portion a of the cab 5 by the hinge member 8 is formed into a single curved window which bulges rearward in a plan view. As a result, when the rear window 6 is opened and the upper swing body 4 is swung in the direction of the opening side of the rear window 6 (the direction of arrow a shown in FIG. 3), the outside air is blown from the opening of the rear window 6 by the arrow b. As described above, the air flow having a substantially arcuate shape in plan view flows along the curved inner surface of the rear window 6 and flows into the cab 5. Therefore, the ventilation inside the cab 5 can be improved. Further, in the present invention, the stopper 10 is provided between the inner surface of the rear window 6 and one end of the cab 5, and the opened rear window 6 has the maximum turning radius R of the upper swing body 4 (shown in FIG. 3). The circle C does not protrude outward. As a result, even if the upper revolving unit 4 is swung when the rear window 6 is open, the rear window 6 is an obstacle (not shown) external to the rear window 6.
It is possible to prevent the vehicle from colliding with and to exert the function of the small turning hydraulic excavator.

The rear surface of the cab 11 is divided into a left rear window 13L and a right rear window 13R, and the two left and right rear windows 13L and 13R are divided.
Are formed in a curved shape in a plan view so as to bulge outward, and the left and right rear windows 13L and 13R are attached to the vertical pillar frame 12 on the rear portion of the cab 11 on the hinge member 1.
I put on a butterfly at 4. As a result, the left and right rear windows 13L, 13R
When only one of them is opened and the upper swing body 4 ′ is swung toward the opening side of the opened rear window,
The same operation as in the case of the cab structure of the first embodiment can be obtained.
However, when the left and right rear windows 13L and 13R are both opened and the upper revolving superstructure 4'is swung, the right rear window 1
3R in the direction of arrow d (shown in FIG. 5), and when turning right, in the direction of arrow e from the opening of the left rear window 13L along the curved inner surfaces of the left and right rear windows 13L and 13R, respectively. As described above, the outside air becomes an air flow having a substantially arcuate shape in plan view and flows into the cab 11. Therefore, it is possible to improve the ventilation of the inside of the cab 11 regardless of whether the upper revolving structure 4'is swung in the left or right direction. Further, in the present invention, the metal fittings are provided for the left and right rear windows, and the left and right rear windows 13L and 13R that are opened are located outside the circle C having the maximum turning radius R (shown in FIG. 5) of the upper turning body 4'as a radius. I tried not to stick out. The operation in this case is similar to that of the cab structure of the first embodiment.

圧ショベルの機能を発揮することができる。According to the present invention, since the rear window of the cab is formed as a single curved window which bulges backward, the upper window of the hydraulic excavator is opened to the rear window by opening the rear window. When swirling in the direction toward the opening side, the outside air flows into the interior of the cabin from the opening of the rear window into a substantially arc-shaped air flow in plan view along the curved inner surface of the rear window. Therefore, when the upper swing body is swung toward the opening side of the rear window, it is possible to improve the ventilation of the inside of the cab.
Further, in another embodiment of the present invention, the rear window of the cab is divided into a left rear window and a right rear window, and the two left and right rear windows are each formed in a curved shape in plan view which bulges outward. Since the left and right rear windows are hinged to the vertical support frame on the back of the cab, when the left and right rear windows are opened together and the upper revolving structure is turned, when turning left, the right turning window opens again At the time of turning, outside air flows into the inside of the cab from the opening of the left rear window along the curved inner surfaces of the left and right rear windows into a substantially arc-shaped airflow in plan view. Therefore, it is possible to improve the ventilation of the inside of the cab when the upper swing body is swung in either the left or right direction. Further, according to the present invention, since the rear window and the left and right rear windows are opened and closed without protruding from the circle having the maximum turning radius of the upper revolving structure as the radius, the upper window is opened when the rear window and the left and right rear windows are open. Even if the revolving structure is revolved, it is possible to prevent the window from colliding with an external obstacle and to exhibit the function of the small-revolution hydraulic excavator.
