Abstract

PURPOSE:To prevent a wind noise by fitting window glass movable forward and afterward in such a way as to be capable of free turn about a turning arm on sliding afterward, and locating the front end of the window glass within a cabin and the rear end thereof outside when a window is opened. CONSTITUTION:When window glass 13 has been shifted afterward with a handle 26 in opening a door window 10, a front slider 28 slides afterward within a front groove 20. Concurrently therewith, the component of a force toward the outside of a cabin as generated on a support axis 29 causes a turning arm 25 to turn and a rear slider 30 to turn within a circular recess 21a. Consequently, the front end of the window glass 13 shifts toward the inside of the cabin and the rear end thereof toward the outside. As a result, the window glass 13 inclines from the external face of a body as shown in a dashed line. In this condition, the rear slider 30 is restricted within a rear groove 21 and slides toward the rear side without any change in posture, thereby opening a window opening 11. According to the aforesaid constitution, a wind noise can be restrained.

These guide rails 19 and 19 are connected to a front groove 20 and a rear groove 21 that extend substantially linearly in the longitudinal direction of the vehicle body 2.
These front grooves 20 and rear grooves 21 are arranged substantially on the same straight line.

On the other hand, a pair of upper and lower fixed arms 23.23 are protruded from the interior side of the front end of the windshield 13, and brackets 2
4, a pair of upper and lower rotating arms 25, 25 are pivotally supported in the vehicle width direction. The protruding end of the fixed arm 23 and the rotating end of the rotating arm 25 are fitted into the front groove 20 and the rear groove 21 so as to be rotatable about the vertical axis and slidable back and forth. Furthermore, a handle 26 that also serves as a locking means is provided protruding from the front end of the windshield 13 on the inside of the vehicle.

The guide rail 19 and both arms 23, 25 disposed on the lower frame 16b will be explained in more detail mainly with reference to FIGS. 3 to 5.

The guide rail 19 is made of resin and is shown in FIGS.
As shown in the figure, it is fitted into a recess formed in the lower frame 16b. As shown in FIG.
and a rear groove 21 are formed respectively, and these grooves 20,
21 has a substantially U-shaped cross section as shown in FIGS. 4 and 5. Of these grooves 20 and 21, the rear groove 21
As shown in FIG. 3, a circular recess 21a having a diameter larger than the width of the rear groove 21 is formed at its front end.

A front slider 28 is provided on the lower surface of the protruding end of the fixed arm 23 and is fitted into the front groove 20 so as to be slidable back and forth. As shown in FIG. 3, the front slider 28 has a substantially perfect circular cross section, and is rotatable about its axis within the front groove 20.

Further, the bracket 24 is screwed to the windshield 13 so as to protrude toward the inside of the vehicle similarly to the fixed arm 23, and a pivot shaft 2 is attached to the protruding end of the bracket 24.
9, the rotary arm 25 is rotatably supported. On the lower surface of the rotating end side of this rotating arm 25 is the rear yt21.
A rear slider 30 is fitted into the circular recess 21a so as to be rotatable around the axis, and is capable of sliding back and forth in the rear groove 21. The rear slider 30 has an oval cross section as shown in FIG. 3, and its long axis is the circular recess 21a.
The width of the rear groove 21 is approximately the same as that of the rear groove 21, and the short axis thereof is approximately the same as the width of the rear groove 21.

3, when the window glass 13 closes the window opening 11, the rear slider 30 is located within the circular recess 21a and the rear groove 2
When the rotating arm 25 is rotated to the position shown by the dotted chain line in the figure in order to open the window opening 11, which is inclined with respect to the longitudinal direction of the window opening 11, The longitudinal directions of the mover 30 and the rear groove 21 coincide, so that the rear slider 30 can be freely fitted into and removed from the rear groove 21. When the rear slider 30 is fitted into the rear groove 21, it can freely slide along the rear groove 21 while its rotation within the rear groove 21 is restricted. .

In order to open the door window 10 from the state where the window opening 11 is closed as described above, one passenger can grasp the handle 2B and push or pull it toward the rear. As the front slider 28 moves rearward, it slides rearward within the front groove 20, and at this time, the rotation arm 25 rotates due to the force exerted on the pivot shaft 29 toward the outside of the vehicle. As a result, the rear slider 30 rotates within the circular recess 21a (as shown by arrow A in FIGS. 3 and 1), and as a result, the front end of the windshield 13 enters inward from the outer surface of the vehicle body. The rear end of the windshield 13 is rotated so as to protrude outward from the outer surface of the vehicle body (as shown by arrow B in FIGS. 1 and 1), and the windshield 13 assumes an inclined position (see 3 and wS5 (point ta line shown).

Then, if the window glass 13 is further moved rearward from the above state, the front slider 28 and the rear slider 30 slide rearward in the front groove 20 and the rear groove 21, respectively. At this time, since the rear slider 30 is restricted from rotating within the rear groove 21, the windshield 13 moves rearward while maintaining the above-mentioned inclined position. (Illustrated by the arrow in FIG. 1), and by moving the window glass 3 backward, the window opening 11 is opened (illustrated by the thirteen-dot chain line in FIGS. 1 and 3).

When the automobile 1 is running in the above state, as shown in FIG. The water will also flow towards the outer side of the vehicle at the rear.

Further, when closing the door window 10, the first handle 26 can be pushed or pulled forward in the opposite manner to the above. In this way, the front slider 28 and the rear slider child 30 slides within the guide rail 19, and the window glass 13 moves forward while maintaining the above-mentioned inclined position (
(arrow E shown in FIG. 1), and this window glass 1
3 is moved further forward, the rear slider 30 enters the circular recess 21a, and as the rotation arm 25 rotates due to the component force generated in the pivot shaft 29 toward the inside of the vehicle, the rear slider 30 moves forward. The side slider 30 rotates (as shown by the solid line F in FIGS. 3 and 5), which causes the rear end of the window glass 13 to rotate toward the inside of the vehicle (as shown by the solid line G in FIGS. 1 and 5). ), and this window glass 13 slides and presses the outside surface of the weather strip 17 to close the window opening 11 (shown by solid lines in FIGS. 1, 3, 4, and 5).
In this case, the outer surface of the window glass 13 is substantially flush with the outer surface of the vehicle body 2. For this reason, air resistance when the vehicle 1 is running can be suppressed to a low level.

Further, the fixed arm 23. A resin cover 32 is provided to cover the bracket 24 and the rotating arm 25, respectively. This cover 32 prevents the fixed arm 23, bracket 24, rotating arm 25, etc. from being seen by the occupants of the vehicle interior.

In addition, in the above embodiment, the opening edge 12 of the window opening 11
Although the guide rail 19 is attached to the frame 16 via the frame 16, the guide rail 19 may be attached directly to the opening edge 12 without the frame 16. In this way, the opening/closing device 14 can be made simpler. It becomes the composition. Furthermore, in the above embodiment,
The opening/closing device 14 is connected to the door window 1 in the sliding door 5.
0 is shown, but in addition to this sliding door 5, it may also be applied to a side window or a quarter window 6.

(Effect of the invention) The effects of this invention are as follows. That is.

When the window opening is opened by moving the window glass, the wind flowing along the outer surface of the vehicle body tends to flow into the cabin through the opened window opening.

Therefore, according to the present invention, a guide rail is provided at the opening edge of the window opening that extends almost linearly along the front-rear direction of the vehicle body, and a rotating arm is provided at the front-rear midway part of the windshield to rotate in the vehicle width direction. The front end of the windshield and the rotary end of the rotary arm are respectively fitted to the guide rails so as to be rotatable about the vertical axis and slidable back and forth, so that the windshield opens the window opening. When this window glass is moved rearward from the closed state to open the window opening, the arm slides along the guide rail so that the front end of the window glass enters the inside of the vehicle body from the outside surface, and the rear end of the same window glass The windshield is designed to protrude outward from the outer surface of the vehicle body, so that the above-mentioned driving wind that is about to flow into the passenger compartment is guided by the outer surface of the window glass and smoothly flows toward the outer surface of the vehicle body behind the window opening. It will flow.

Therefore, this running wind is prevented from colliding with the rear opening edge of the open window opening or the front edge of the windshield, thereby preventing the generation of wind noise and minimizing air resistance when driving. .

Moreover, since the guide rail for moving the window glass extends almost linearly along the longitudinal direction of the vehicle body, even if the guide rail is provided at the opening edge of the window opening, the opening edge provided with this guide rail will be The width dimension can be kept small. Therefore, the guide rail can be provided as described above without unnecessarily narrowing the vehicle interior space.
