Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for storing a windshield in a cabin of a construction machine, an agricultural machine or the like, particularly, a cabin of a backhoe.

[0002]

2. Description of the Related Art A windshield in a conventional backhoe of a cabin specification is divided into upper and lower portions, and in summer or the like, the windshield is opened so that air can be ventilated to facilitate work. At this time, the upper glass was slid up and stored in the ceiling, and the lower glass was removed to provide a storage space on the left or right or rear wall in the cabin.

[0003]

[Problems to be Solved by the Invention] Since the lower glass must be once removed as described above, the attaching and detaching work is troublesome, and the attaching and detaching work may damage the glass only by hitting other parts. It must be done carefully, and if it is not fixed firmly even when stored, it may fall down due to vibration and be damaged.
Also, it is necessary to secure a storage space for the glass after it has been removed.If the cabin is a small cabin, there is no storage space and it can be left outside of the aircraft, or it can be stored forcibly for work. It was in the way.

[0004]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention has a structure in which a windshield provided on a front surface of a cabin is divided into upper and lower portions so that the windshield can be opened upward. An inverted L-shaped guide rail for guiding and storing the upper glass and the lower glass is provided in the ceiling from above, and the front part of the guide rail is provided with grooves of different widths for the upper glass and the lower glass on the same line, Is one in which two grooves for each glass are provided in parallel.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved by the present invention and the means for solving the problems are as described above. An embodiment of a backhoe with a cabin specification shown in the attached drawings will be described.
1 is an overall perspective view of the backhoe, FIG. 2 is a cross-sectional side view of the cabin, FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2, and FIG.
2 is a sectional view taken along the line BB in FIG.
6 is an enlarged sectional view of the roof window portion. In FIG. 1, a crawler-type traveling device 1 is provided on both sides of a traveling frame 2 of a backhoe, a blade 3 is protruded from a front end of the traveling frame 2, and a swivel frame 4 is mounted on the traveling frame 2 so as to be pivotable.

[0006] A boom 5 is pivotally connected to the front end of the revolving base frame 4 so as to be able to rotate up, down, left and right. Each is configured to be rotatable by a hydraulic cylinder. An engine room 9 is provided on the rear part of the swivel frame 4, and a cabin D is mounted on a front part of the engine room 9. In the cabin D, a driver's seat, an operation lever, and the like are arranged.

[0007] The cabin D has one side which can be accessed as a door 13 and glass is fitted into the front, side, rear, and front portions of the ceiling to secure a view.
The glass at the front of the ceiling serves as a roof window 12 so that the front upper part is also visible.
The sun is dazzling during the summer season, so the inside is shielded by curtains. That is, as shown in FIG. 6, reinforcing ribs 15 are fixed to the ceiling plate 14 for reinforcing the ceiling side of the roof window 12 in the left-right direction,
A roll curtain 16 can be accommodated in the reinforcing rib 15, and the reinforcing rib 15 on the drawer side has a receiving plate 15a.
Is provided to receive the pull-out rod 16b of the roll curtain 16.

Further, guide rods 19 are protruded from the side plate 31 of the cabin D main body along the roof window 12, and a hook 17 is provided on the front plate 18 of the cabin D main body to pull out the roll curtain 16. The drawer rod 16b can be locked at the same position. When the lock of the pull-out rod 16b is released, the roll curtain 16 is wound up by a spring provided on the core 16a and stored in the reinforcing rib 15, and the pull-out rod 1
6b is received by the receiving plate 15a.

The windshield, which is a main part of the present invention, is configured to be housed in the upper ceiling. That is, the lock levers 20 and 21 and the handles 22.
23, guide rollers 24, 25, 26, and 27 are disposed on the upper and lower sides of the inside of each of the front upper glass 10 and the front lower glass 11, and a wiper 29 is provided on the front of the front upper glass 10. Are arranged.

Then, the side glass 33 of the cabin D
An inverted L-shaped guide rail 30 is provided along the ceiling from the front side plate 31 of the front 34, and the guide rail 30 is provided with guide rollers 24 and 25 provided on the front upper glass 10.
And a groove 30b for fitting the guide rollers 26 and 27 provided on the lower front glass 11, and the width W1 of the groove 30a is different from the width W2 of the groove 30b. In this embodiment, the groove 30a is replaced with the groove 30b.
Larger (W1> W2), the guide rollers 24
25, 26, and 27 have sizes corresponding to the widths of the grooves 30a and 30b, respectively.

Further, as shown in FIGS. 3 and 4, the guide rollers 24 and 25 are fitted in the shallow position of the groove 30a, and the guide rollers 26 and 27 are fitted in the deep position of the groove 30b so that they can roll. The groove 30b is formed in an L shape from the front of the side glasses 33 and 34 along the ceiling, and the groove 30a is formed in an L shape from the front of the side glass 34 to the ceiling above the groove 30b. Although the guide rail 30 is straight, the groove at the front of the side glass 34 is formed in two steps on the same line as shown in FIG. 26 and 27 can be rolled, the shallow part is widened and the groove 30a
The guide rollers 24 and 25 can be rolled. The guide rail at the ceiling of the side plate 31 is shown in FIG.
As shown in FIG. 3, the groove 30a is arranged on the upper side to accommodate the upper front glass 10, and the groove 30b is arranged in parallel below the groove 30a to accommodate the lower lower glass 11.

With this configuration, when the front glass is to be opened on a sunny day when the wind is required, first, the lock lever 20 of the front upper glass 10 is opened.
Is released and the handle 22 is lifted with the handle 22, the guide rollers 24 and 25 roll along the groove 30a and are stored in the upper part of the ceiling, and if the lock lever 20 is locked, it can be fixed at that position. Next, when the lock lever 21 of the lower front glass 11 is released and the grip 23 is lifted, the guide rollers 26 and 27 roll along the grooves 30b and are stored in the lower part of the upper front glass 10 on the ceiling. By rotating the lock lever 21, the lock can be performed and the windshield can be opened. The guide rollers 26 and 27 pass through the guide rails of the guide rollers 24 and 25 of the upper front glass 10, but pass through the deep portion of the groove and do not rattle because the width of the groove is different.
Even at the branch between the groove 0a and the groove 30b, it is smoothly stored without being caught or entering the other groove.

[0013]

According to the present invention, the following effects can be obtained. That is, not only the upper front glass but also the lower front glass can be stored in the ceiling, so that the glass can be stored by simple operation just by sliding, and it can be damaged because it is not removed. It was easier to handle and the space could be used more effectively.

Further, in the front guide rail on which the glass slides, the width and depth of the groove for the upper glass and the groove for the lower glass are different from each other, so that even if the guide grooves exist on the same line, they are mutually opposite. There is no possibility of erroneous operation without entering the groove. Since two guide grooves are present on the same line, space can be saved, the pillars can be made thinner and the visibility is not deteriorated, and the manufacturing cost can be reduced.
