In a window frame structure according to one embodiment of the prior art shown in FIG. 11, a window frame 9 having a Y-shaped cross section and a run channel 10 inserted inside the window frame 9 are provided.
And a rubber member 1 interposed between the window frame 9 and the opening edge of the cabin 4. The innocent book 1 has a U-shaped recess 15 holding the rear and outer surfaces of the window frame 9. And a cross-sectional shape having a deep groove-shaped slit 16 and a receiving seat 3 located behind the concave portion 15.
The window frame 9 is inserted into the recess 15, the flange 7 at the opening edge of the cabin is inserted into the slit 16, and the window frame 19 is held with the receiving seat 3 seated on the receiving surface 8 at the opening edge of the cabin. I have to. Further, the rubber material 1 has a substantially S-shaped basic cross-sectional shape in which the concave portion 15 and the slit 16 are arranged side by side in the opposite direction, and a water sealing rib extending from the outdoor end of the basic cross-sectional shape to the opposite concave side. 2 is formed in a cross-sectional shape. In addition, 5 is an inner panel and 6 is an outer panel.

Moving windows 20'a and 20'b are arranged in window holes 13 'provided in the door 12' of the cab 11 'of the hydraulic excavator, and the moving windows 20'a and 20'b are indicated by arrows A and B, respectively.
The window can be set in an open state and a closed state. Cab 11 'of hydraulic excavator in FIG.
Is relatively square in side view, the upper and lower edges of the window hole 13 'are parallel to each other, and the moving windows 20'a, 20'b
Can be moved, and the glass surface can be made large in the vertical direction.

を出すことができなかった。In recent years, many cabs of construction machines often use an arc shape in a side view in order to give a soft visual impression to the periphery. When a sliding window in the front-rear direction as shown in FIG. 11 is applied to such a cab that uses a large number of arcs in a side view, a window frame that is vertically parallel to the external appearance of the arc-shaped cab appears. It does not match well and spoils aesthetics. In recent years, in cabs of construction machinery, a design with a high glossiness using a lot of glass surfaces is sometimes desired. However, when a sliding window as shown in FIG. It was difficult to cover the vicinity of the upper center with a glass surface, and glossiness could not be obtained.

ある。In the window frame structure shown in FIG. 11, a run channel 10 is fitted inside a window frame 9 (for a sliding window) having a Y-shaped cross section, but separately from the run channel 10. The rubber material 1 is interposed between the outer peripheral edge of the window frame 9 and the opening edge of the cabin 4. Therefore, since the window frame 9 is not securely fixed to the cabin 4, the window glass is likely to vibrate when the construction machine is running or working, and the window glass is deformed in the window frame 9. This may adversely affect the sliding movement of the window glass.

である。[0008] Due to the configuration of the window of the cab, when the window is closed, the moving window is located in a range of a portion where the window frame is not covered by the fixed window. When the window is open, the movable window is located on the back side of the fixed window. According to this, the shape of the fixed window can be determined regardless of the shape of the window hole, it is possible to obtain a window that matches the cab that uses a lot of arc shapes, and it is also possible to take a large glass surface around the cab It is.

ようにした。[0009] Furthermore, a third seal member is fitted to an outer edge of a portion of the window frame that is not covered by the fixed window, and the third seal member is fixed to the window frame from the outer edge of the window frame. The lip has a lip extending to substantially the same position as the edge of the window.

る。When the fixed window is made larger than the window hole or the window frame, the moving window located in the window frame becomes smaller than the fixed window, and the edge of the fixed window and the moving window become discontinuous. According to the present invention, since the third seal member extends to near the edge of the fixed window, the image of the edge of the fixed window and the edge of the third seal member are continuous, so that the entire window is provided. As a result, an appearance image having a sense of unity can be obtained.

When the seal member or the first seal member and the third seal member are integrally formed, the number of parts of the seal member can be reduced, so that the productivity can be improved, and the rubber or the like constituting the seal member can be used. When contracted due to aging, there is no gap between the sealing members, and the sealing performance can be maintained.

It is set to a value, and the sliding movement of the moving window can be performed smoothly.

According to this, if the movement of the moving window is stiff when it is slid, the small-diameter gap adjusting member is selected and replaced. Since the gap increases and the vertical play of the moving window is in an appropriate state, the sliding movement of the moving window can be made smooth. Also, when the moving window is slid, the play in the vertical direction is in an appropriate state, so that the sliding movement of the moving window can be smooth. If the play in the vertical direction is large when the moving window is slid, the play can be adjusted and set to an appropriate state by selecting and replacing the large-diameter gap adjustment member. it can.

Referring to FIG. In the present embodiment, a window hole 13 formed in the outer wall of the cab 11 and a substantially U-shaped window frame 14 (sash frame 31) formed along the outer periphery of the window hole 13 and having one opened. (Shown in FIG. 3), a first seal member 33 at least partially housed in the sash frame 31, a movable window 20 slidably guided by the first seal member 33, and the window A second seal member 40 fitted to an edge of a flange plate forming an outer end of the frame 14,
The fixed window 22 is fixed to the second seal member 40 by adhesion and fixedly covers a part of the window hole 13 and a part of the window frame 14.

ル部材を同一の型で形成できるというメリットがある。A third sealing member 45 (shown in FIGS. 5 and 7) fitted to the window frame 14 (flange plate edge 30) at a portion not covered by the fixed window 22 is provided. The sealing member 45 is formed to extend from the outer edge of the flange plate edge 30 to a position substantially equal to the position of the edge 46 of the fixed window 22. As a result, the third sealing member 45 is extended to near the edge 46 of the fixed window 22, so that the end 46 of the fixed window 22 and the edge of the third sealing member 45 become a continuous image, and the entire window becomes Thus, an appearance image having a sense of unity can be obtained. When the second seal member 40 also extends to the vicinity of the end 46 of the fixed window 22 (the third seal member and the second seal member have substantially the same cross-sectional shape),
Although the size of the seal member is increased, there is an advantage that the second seal member and the third seal member can be formed by the same mold.
