Is easy.
[0014]
Next, a vehicle window opening and closing device will be described. As shown in FIGS. 5 and 6, the window handle 18 is attached to a handle plate 35 fixed so as to sandwich the glass surface from the inside and outside of the window 14, and the lower end of the window handle 18 is positioned downward. It is formed so as to be able to rotate approximately 90 degrees until reaching a forward-facing position. Further, the window handle 18 is provided with a locking piece 36 projecting in one direction substantially perpendicular to the longitudinal direction when viewed from the side, and with the lower end of the window handle 18 facing downward and vertically, the locking piece 36. Is formed so as to face the rear of the window handle 18. At this time, the locking piece 36 is locked to the stopper 38 of the rear window frame 37 and is locked in the closed state so that the window 14 does not open outward. Further, a cushion member 39 having a flat conical head is fixed to the outside of the window handle 18.
[0015]
Here, one hinge plate 15b of the hinge 15 is attached to the front edge portion of the window 14, and the other hinge plate 15c is attached to the rear edge portion of the door 13, so that each window 14 and door 13 are hinge pins. 15a is formed so as to open and close around the same axis center. An L-shaped bracket 40 is fixed to the inside of the cabin of the window-side hinge plate 15b, and a cylinder case-side hinge 41a of a damper 41, which is a biasing means for the window, is pivotally attached to the horizontal plane portion of the bracket 40. Install so that it can rotate horizontally.
[0016]
Further, a bracket 42 is fixed to the cabin rear window frame 37 side, and a rod side hinge 41b of the damper 41 is pivotally attached to a horizontal surface portion of the bracket 42. The damper 41 is biased in the direction in which the rod protrudes, and as shown in the figure, the damper 41 is interposed between the window-side bracket 40 and the cabin-side bracket 42 in a compressed state.
[0017]
Thus, as indicated by a two-dot chain line in FIG. 5, after the window handle 18 is rotated in the horizontal direction to unlock the window 14 from the closed state, the window 14 is opened by pushing the window handle 18 outward. start. When the window 14 is opened from the closed state shown by the solid line in FIG. 6, the damper 41 is compressed until the cylinder case side hinge 41a reaches the line L connecting the hinge pin 15a and the rod side hinge 41b. Therefore, the opening operation force is slightly large.
[0018]
However, as shown by the two-dot chain line in FIG. 6, when the window 14 is further opened and the cylinder case side hinge 41a moves to the outside of the line L, the cylinder case side hinge 41a becomes over the dead point and the damper. Since 41 extends, an urging force that presses the window 14 outward is generated through the window-side bracket 40. When the operator pushes the window handle 18 with a light operating force, the window 14 rotates in the direction of the arrow.
[0019]
Thus, as shown in FIG. 7, the window 14 rotates forward approximately 180 degrees and approaches the door 13, and at this time, the damper 41 tries to extend to the longest position. Can be held in. Further, since the cushion member 39 abuts against the glass surface of the door 13 when the window 14 approaches the door 13, the impact between the window 14 and the door 13 can be reduced. Further, since the cushion member 39 is provided on the outside of the window handle 18, it is possible to absorb the impact of the most forceful portion when the window 14 is opened to a minimum.
[0020]
It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
[0021]
【The invention's effect】
As described above, in the present invention, in a vehicle provided with a window and a door that can be opened and closed on one side of the side surface of the cabin, the damper is a biasing means between the one window and the cabin frame. The cylinder case side hinge of the damper is pivotally attached to the inner bracket of the window side hinge plate, and the hinge of the rod side of the damper is pivotally attached to the rear frame side bracket of the cabin, so that the damper projects in the direction in which the rod protrudes. When the window is biased and opened outward from the closed state to extend beyond the dead center, a biasing force is generated that pushes the window outward through the inner bracket, thereby rotating horizontally. Since it is configured to be able to generate an urging force that presses the window outward through the bracket on the window side, if the operator presses the handle with a light operating force, the window can be easily rotated, and the window or door can be very easily About 180 It can be held in the open state.
[0022]
Further, the cushion member is formed by flattening a conical head on the outside of a handle provided by sandwiching the glass surfaces of the glass window and the glass door from inside and outside, so that the window and the door are substantially omitted. When opening at 180 degrees, the impact is alleviated, that is, when the windows and doors are opened, the impact of the most forceful portion can be absorbed to the minimum, and the glass surface can be protected. Thus, the window and the door can be easily fixed in a state where the window and the door are largely opened at about 180 degrees, and the window and the door are pivoted on the same axis by the common hinge pin to narrow the distance between the window and the door. Combined with the improved transparency of the peripheral surface, the operator's field of view becomes wider and driving operability and safety can be ensured.
