Description

Description: TECHNICAL FIELD The present invention relates to a door glass positioning method for positioning a door glass of an automobile at a fully closed position thereof.

Conventionally, a door glass that is vertically mounted on a side door or a back door of an automobile is firmly fixed to a glass supporting member of a window regulator, and the window regulator operates so that the glass is at the lowermost fully opened position and at the most open position. It was supported so as to move up and down between it and the fully closed position above.

By the way, it is unavoidable that the assembling state of each part of the door body to which the door glass is attached and the window regulator are slightly different depending on the vehicle due to an assembling error at the time of manufacture. Therefore, if the door glass is fixed to its supporting member as in the conventional case, it is not easy to correctly position and attach the door glass to the door body, and the door glass is lifted to the correct fully closed position. There were things I couldn't do. Conventionally, when such a mounting failure occurs, the work of re-adjusting the position of the door glass has been performed, but this work is very troublesome and requires a great number of man-hours.

OBJECT The object of the present invention is to eliminate the above-mentioned conventional drawbacks and to provide a door glass positioning method for an automobile that does not require a readjustment work for the mounting position of the door glass.

Structure In order to achieve the above object, the present invention supports the door glass on a glass support member of a window regulator that raises and lowers the door glass so as to be tiltable within a plane including the glass surface, and an up-stopper with respect to the door body. The glass support member is lifted together with the door glass in a state of being vertically movable, and when the door glass is lifted to its uppermost position, the stopper fixed to the door glass and the up stopper are brought into contact with each other. Then, a door glass positioning method for an automobile is proposed in which the up-stopper is fixed to the door body in that state.

Embodiments Embodiments of the present invention will be described below with reference to the drawings, and the above-mentioned conventional defects will be more specifically clarified with reference to the drawings.

FIG. 1 is a front view showing an example of a side door 2 of an automobile having a door glass 1, and FIGS. 2 and 3 are sectional views taken along line II-II and III-III of FIG. 1, respectively.

The door shown in FIGS. 1 to 3 is an outer panel 3 located outside the vehicle when the door is mounted on a vehicle body (not shown).
And a door frame (sash) 6 fixed to the main body 5, and a door body 5 having an inner panel 4 facing the inner panel 4 and a door frame (sash) 6 disposed between the inner panel 4 and the outer panel 3. The window regulator 7 is arranged in the space.

Although various types of devices can be used as the window regulator, the window regulator 7 shown as an example in the figure.
Are two links 8 and 9 pivotally connected to each other by a pin in the center, a drive device 10 that drives one link 8 in the arrow direction, and a guide link 11 that guides the lower end of the other link 9, The guide rollers 12 and 13 rotatably supported on the upper ends of both links 8 and 9 have a channel-shaped glass support member 14 rotatably fitted therein, and the door glass 1 will be described later on the support member 14. Supported by the embodiment. The window regulator 7 is supported by the inner panel 4 of the door. Since the window regulator 7 itself is the same as a known one, further description will be omitted.

To move the door glass 1 up and down, the drive device 10 is manually or electrically operated to drive the link 8 in the direction of the arrow, and the glass support member 14 is operated in the vertical direction. With this movement, the door glass 1 moves up and down inside the frame 6 while slidingly contacting the glass run 15 (see FIG. 2) attached to the door frame 6.

As described above, the door glass 1 is supported by the glass support member 14 and is driven up and down. However, in the conventional supporting device of this type, as described above, the door glass is attached to the glass support member by bolts or the like. It was fixed together. For this reason, it is difficult to mount the door glass at the correct position due to a slight assembly error in the door frame, the window regulator, the door body, or the like.

That is, if the door glass 1 is properly positioned and attached to the door frame 6, when the glass 1 is lifted to the uppermost position (fully closed position), the glass 1
As shown by the solid line in FIGS. 2 and 3, the door frame 6 is positioned with a predetermined gap G1. However, if the door frame 6 or the window regulator 7 has an assembling error, even if the door glass 1 is correctly positioned and attached to the support member 14, when the glass 1 is brought to the uppermost position, FIG. In some cases, a part of the glass 1 opens a large gap G2 with respect to the door frame 6 as indicated by a chain line, or conversely, the other part has a gap too small with respect to the frame 6. If the gap G2 becomes large, not only does it look bad, but wind noise and rain leaks occur when the vehicle is running, and if the gap is too small as in the latter case, the glass run 15 causes the glass run 15 to move to the door frame. Since it is strongly pressed against 6, the inconvenience of early wear of the glass run is unavoidable. For this reason, when the door glass 1 is improperly mounted, it is necessary to perform adjustment work such as adjusting the mounting position of the window regulator on the inner panel to readjust the mounting position of the door glass on the door frame. Such repair work is very complicated.

Therefore, in the door glass positioning method according to the present invention, the door glass 1 is not fixed to the glass supporting member 14 integrally, but is supported so as to be tiltable, and its position can be adjusted by the raising operation of the door glass 1. Is configured. The details will be made clear below.

As shown in FIGS. 1, 3 and 5, a support bracket 20 is fixed to the glass support member 14 at a substantially central portion in the longitudinal direction thereof, and a bolt 21 is fixed to an upper portion thereof by a nut 22. . Further, a portion of the bolt 21 on which the screw is not formed is fitted into a hole formed in the door glass 1 via a bush 23. Therefore, the door glass 1 is supported by the support member 14 in such a manner that the central portion thereof can be tilted about the bolt 21.

On the other hand, as shown in FIG. 1, FIG. 2, FIG. 4, and FIG.
4 are fixed to each other, and locking pins 25, 25 are provided on the bottom surface thereof.
The leaf springs 26, 26 are fixed by the leaf springs, and the lower end portions of the door glass 1 are placed on these leaf springs. Each of the leaf springs 26, 26 is in a free state shown by a chain line in FIG. 4 when the door glass 1 is not set, but when the door glass 1 is placed, it is elastically deformed by a load thereof as shown by a broken line. Therefore, each end of the door glass 1 is biased upward by the springs 26, 26, and can move downward while elastically deforming the springs 26, 26. In this way, the door glass 1 is tiltably supported within a plane including the glass support member 14 of the window regulator 7 that raises and lowers the glass 1 and the glass plate.

In addition, stoppers 2 are provided by bolts 27, 27 and nuts at appropriate positions on the door glass 1, in the illustrated example, at both ends thereof.
8 and 28 are fixed, and these stoppers 28 and 28 can abut on up-stoppers 29 and 29 attached to the inner panel 4 of the door body 5. As shown in FIG. 2, these up-stoppers 29, 29 each have a nut portion 29a having a thread formed therein, and a bolt 31 inserted into a vertically elongated long hole 30 formed in the inner panel 4 is used as the nut portion. The up-stoppers 29, 29 can be fixed to the inner panel 4 by being screwed onto the 29a. By loosening the bolt 31 and moving it up and down in the elongated hole 30, the height position of the up stoppers 29, 29 can be adjusted.

When the door glass 1 is attached, the glass 1 is tiltably supported with respect to the support member 14 as described above, and then the door glass 1 is lifted upward by the window regulator 7. At this time, if the attachment state of the door glass to the door frame 6 is incorrect, the glass 1 rises in a state of being slightly inclined with respect to the upper side portion 6a of the door frame 6 as shown by the chain line in FIG. Go. However, if this is further raised and raised to the uppermost position, the glass run 15
When it is strongly hit (the part indicated by X in the example of FIG. 1)
Receives a reaction force from the glass run 15, so that the glass 1 slightly rotates about the bolt 21 in the counterclockwise direction in FIG. As a result, the portion indicated by Y of the door glass 1 is lifted upward, and the entire door glass 1 is eventually separated from the door frame 6 by a predetermined gap G1 (second
(Fig.) Is adjusted to the correct position. In this way, the door glass 1 adjusts its position by its ascending operation.

Until the above operation is completed, the above-mentioned bolt 31 is loosened so that the up stoppers 29, 29 can freely move up and down. That is, with the up stoppers 29, 29 assembled to the door body 5 so as to be vertically movable,
The glass support member 14 is raised together with the door glass 1 as described above. By doing so, the door glass 1 can be moved to the uppermost position and its posture can be adjusted by itself without being restricted by the up-stoppers 29, 29. Thus, when the door glass 1 is raised to its uppermost position, the stoppers 28, 28 fixed to the door glass 1 and the up-stoppers 29,
As shown in FIG. 2, the up-stoppers 29, 29 are fixed to the inner panel 4 of the door body 5 by tightening the bolts 31 in this state.

In this way, when the door glass 1 is lowered and lifted again, the stoppers 28, 28 are lifted up.
Upon hitting 9, 29, the glass 1 is stopped at a predetermined uppermost position, at which time the glass 1 occupies a predetermined correct position with respect to the door frame 6 as shown in FIG. Be positioned in position.

Therefore, if the door glass 1 is brought to the uppermost position during normal use without any special reworking work, the position can be set correctly, and an excessive external force is applied to the glass run 15 or a reverse operation is performed. In addition, a large gap is created between the door frame and the door frame, and the appearance does not deteriorate, and there is no inconvenience such as rain leak or wind noise.

Even when the door glass 1 is tilted in the direction opposite to the state shown by the chain line in FIG. 1, in the same manner as described above,
You can adjust its position.

During normal use, the door glass 1 can be tilted when moving up and down, but the leaf springs 26,
Since the upward biasing force of the spring 26 acts, the glass 1 does not rattle in the vertical direction when the glass 1 moves up and down.

Further, as shown in FIGS. 1 and 2, the lower ends of the other leaf springs 32, 32 are fixed to the holding brackets 24, 24, and the free end side thereof holds down the door glass 1, and Since the spacers 33, 33 that come into contact with the glass surfaces are fixed to the brackets 24, 24, it is possible to prevent the door glass 1 from rattling in the left-right direction in FIG.

The portions of the leaf springs 26, 26; 32, 32 that come into contact with the glass surface are coated with a soft synthetic resin such as vinyl chloride,
Alternatively, by sticking a tape made of a similar material, it is possible to prevent the generation of abnormal noise due to the contact between the leaf spring and the door glass and prevent the inconvenience of scratching the glass surface.

Further, as shown in FIGS. 6 to 8, the glass support member 1
The support pins 35, 35 of the rollers 36, 36 are attached to the long holes 34 of the support bracket 124 fixed to the door glass 1 by the door glass 1.
The leaf spring 3 is supported by the glass surface of the roller so as to be able to approach or separate from each other, and these rollers 36, 36 are fixed to the bracket 124.
It is also possible to press the glass surface of the door glass 1 by pressure by means of 7, and thereby prevent the door glass 1 from rattling. In this configuration example, since the rollers 36, 36 are rotatable, abnormal noise is generated due to contact between the rollers and the glass surface,
In addition, scratches on the glass surface can be prevented more effectively. It should be noted that the same reference numerals are given to the parts in FIGS. 6 to 8 which are substantially the same as those in the above-described embodiment. In each of the above-mentioned embodiments, the door glass 1 is brought to the uppermost position. Even after the tilt state is corrected and the position is adjusted, the door glass is kept tiltably supported by the support member 14, but after the adjustment, the door glass 1 is immovable on the glass support member 14 by a bolt or the like not shown. It may be fixed to. If this is done, there is no risk of the door glass 1 rattling during normal use.
2, 37 may be omitted.

Of course, the present invention can also be applied to a method of positioning a door glass supported by a door other than a side door or a sashless door without a door frame.

Effect According to the present invention, the door glass is tiltably supported by the glass support member and is raised to the uppermost position, whereby the door glass can be automatically adjusted to the correct position.
Moreover, since the up-stopper of the door body is fixed in this state, thereafter, every time the door glass is raised to the uppermost position, the stopper fixed to the glass is brought into contact with the up-stopper so that the door glass is correctly placed at the uppermost position. Can be brought to the upper closed position. In this way, the door glass can be correctly positioned in its fully closed position very easily, and there is no need for reworking.
