BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window panel elevating device for elevating and lowering a window panel of an automobile door which can be moved up and down.

[0002]

2. Description of the Related Art As a conventional window panel elevating device, there is, for example, a device as shown in FIG. 5 (introduced by Nissan Motor Co., Ltd. in June 1990, "Introduction of R10 type car" 40). FIG. 5 shows a front door 1 of, for example, a four-door hardtop as a door for an automobile, as viewed through the interior of the vehicle, and through a lifting device 5 of a window panel 3. The window panel 3 is supported on the door panel 7 so as to be able to move up and down. An elevation drive device 9 that drives the window panel 3 up and down is provided in the door panel 7.

The lifting drive 9 is provided with a regulator motor 11
And the like, a main arm 15, a sub arm 17, guide channels 19 and 21, and the like. One guide channel 19 is fixed to the lower end of the window panel 3, and the other guide channel 21 is fixed to the door panel 7.

Accordingly, by driving the regulator motor 11, the window panel 3 can be moved up and down with respect to the door panel 7 via the main arm 15 and the sub arm 17.

On the other hand, a guide rail 23 is arranged in the door panel 7. The guide rail 23 includes a vertical portion 23a disposed along the vertical direction of the door panel 7,
The inclined portion 23b is formed continuously from the upper end portion 23c of the vertical portion 23a and bent toward the door opening side (left side in the drawing) in the door width direction. The inclined portion 23b is provided to dispose the guide rail 23 while avoiding the door lock 10 attached to the door opening side of the door panel 7. A guide roller 25 supported at the lower part of the window panel 3 is guided by the guide rail 23 to ascend and descend.

The guide rail 23 and the guide roller 25 will be further described with reference to FIG. 6 which is a sectional view taken along line VI-VI of FIG.

As shown in FIG. 6, the cross section of the guide rail 23 is formed in the shape of a channel material. Guide surface 27a facing
27b. These rolling surfaces 26a, 27
b and the guide surfaces 17a and 27b are both formed continuously from the vertical portion 23a to the inclined portion 23b. The guide rail 23 includes an upper bracket 29a and a lower bracket 29.
b attached to the door inner panel 31 of the door panel 7.

The guide roller 25 has a circumferential surface 25a which is guided by rolling on rolling surfaces 26a and 26b.
b faces the guide surfaces 27a and 27b. The guide roller 25 is supported by a pivot 33a of a support member 33 provided below the window panel.

Accordingly, when the window panel 3 is driven to move up and down, the guide roller 25 is guided up and down by the vertical portion 23a and the oblique portion 23b of the guide rail 23.

In FIG. 6, reference numeral 35 denotes an inner stabilizer, and reference numeral 37 denotes an outer stabilizer. The inner stabilizer 35 is fixed to the door inner panel 31 via a bracket 39, and the outer stabilizer 37
Is the door molding 4 attached to the door outer panel 41
3. The stabilizers 35 and 37 guide the window panel 3 in sliding contact. 45 is a door trim.

With the above construction, the window panel 3 can be driven up and down with respect to the door panel 7 by the lifting drive device 9, and the guide rollers 25 are guided by the guide rails 23 and the stabilizer 3
The window panel 3 is supported by sliding contact at 5, 37.
Can be smoothly moved up and down along a predetermined trajectory.

FIG. 7 shows a stopper for determining the fully closed position of the window panel 3. A first stopper 47 is provided on the window panel 3 side, and the door inner panel 3 is provided.
A second stopper 49 is provided on one side. When the window panel 3 rises to the fully closed position, the first
The stopper 47 contacts the second stopper 49 to position the window panel 3.

[0013]

By the way, in the case of the above structure, when the window panel 3 rises to the fully closed position, as shown in FIG. 6, the guide roller 25 and the stabilizers 35 and 37 are connected. It is difficult to secure a large distance S, and it is difficult to secure the support rigidity of the window panel 3 at the fully closed position. As a result, for example, the suction amount of the window panel 3 due to the difference in the air pressure inside and outside the vehicle compartment during high-speed running increases, and the increase in the vertical driving force based on the displacement of the window panel 3 becomes extremely large, and a large vertical driving device is required. There was a problem of becoming.

Further, even when the vehicle is not running at a high speed as described above, the window panel 3 may be displaced in the vehicle width direction when the window panel 3 is fully closed. That is, since the first stopper 47 abuts the second stopper 49 as shown in FIG. 7, a downward force F1 acts between the two stoppers 47 and 49, and an upward force is applied between the guide channel 19 and the main arm 15. Force F2 works. The forces F1 and F2 cause a rotational moment to act on the window panel 3 toward the interior of the vehicle, causing the window panel 3 to fall down and the fully closed position of the window panel 3 to be unstable.

The support rigidity of the window panel 3 is such that a plurality of guide rollers 25 are provided.
Can be increased by increasing the number of support points.

However, if a plurality of guide rollers 25 are provided on the guide rail 23 having the oblique portion 23b, the window panel 3 will rotate when the guide roller 25 moves to the vertical portion 23a as shown in FIG. And On the other hand, since the elevation drive device 9 prevents the rotation of the window panel 3, the window panel 3 cannot actually be elevated.

Accordingly, an object of the present invention is to provide a window panel elevating / lowering device which can increase the support rigidity of the window panel 3 at the fully closed position with a simple structure.

[0018]

SUMMARY OF THE INVENTION The present invention provides a window panel which can be moved up and down with respect to a door panel, an elevating drive device which drives the window panel up and down, and which is disposed in the door panel and extends along a vertical direction of the door panel. A vertically extending portion and an inclined portion continuously formed from an upper end portion of the vertically extending portion and bent in the door width direction, and a guide surface facing the door thickness direction is continuously formed from the vertically extending portion to the inclined portion. A guide rail having a main guide roller supported by a lower end of the window panel, fitted between guide surfaces of the guide rail, and guided up and down along the guide rail; and a door above the main guide roller. An auxiliary guide roller supported by the window panel so as to be shifted in the width direction and fitted to an outer surface of the oblique portion at least at a fully closed position of the window panel. It is characterized in.

[0019]

In the fully closed position of the window panel, the main guide roller is fitted on the guide surface of the guide rail, and the auxiliary guide roller is fitted on the outer surface of the oblique portion. Therefore, the window panel is supported at two places, the main guide roller and the auxiliary guide roller, and the support rigidity is significantly improved. When the window panel is lowered and the main guide roller reaches the hanging portion, the auxiliary guide roller separates from the guide rail, and only the main guide roller is guided up and down by the hanging portion of the guide rail, and is supported at one place. Smooth guidance of the window panel by the guide can be achieved.

When the window panel moves from the fully open position to the fully closed position again, the window panel is raised by the guide of only the main guide roller until the main guide roller moves to the oblique portion. Then, at the fully closed position after the main guide roller has moved to the oblique portion, the auxiliary guide roller is fitted to the outer surface of the oblique portion of the guide rail, and stable support at the above fully closed position can be performed.

[0021]

Embodiments of the present invention will be described below.

FIG. 1 is a perspective plan view of a vehicle door to which a window panel elevating device according to an embodiment of the present invention is applied, as viewed from the inside of a vehicle cabin. FIG. 1 corresponds to FIG. 5, and the same components as those in FIG.

Also in this embodiment of the present invention, the guide rail 51 is provided with a vertically extending portion 51a arranged along the vertical direction of the door panel 7, and a door opening side in the door width direction from the upper end portion 51c of the vertically extending portion 51 (paper surface). (Left side) and an inclined portion 51b bent to the left.

A main guide roller 53 is supported at the lower end of the window panel 3, and an auxiliary guide roller 55 is supported on the window panel 3 above the main guide roller 53. The main guide roller 53 has the same configuration as the guide roller 25 shown in FIGS.

FIG. 2 is a perspective view of the main guide roller 53 and the auxiliary guide roller 55 located in the inclined portion 51b, FIG. 3 is a sectional view taken along the line III-III of FIG. 2, and FIG. The positional relationship of the auxiliary guide roller 55 is shown.

As shown in FIG. 2, the guide rail 51 is formed in a channel shape in cross section, and has rolling surfaces 26a, 26b and guide surfaces 27a, 27b continuous from the vertical portion 51a to the inclined portion 51b. ing. This rolling surface 26
a, 26b and guide surfaces 27a, 27b have the same configuration as that of FIG.

The main guide roller 53 has a peripheral surface 53a that is guided by rolling on the rolling surfaces 26a and 26b, and a side surface 53b.
Are opposed to the guide surfaces 27a and 27b. The main guide roller 53 is supported by a pivot 59 of a main support member 57 bolted to the lower end of the window panel 3.

As shown in FIG. 3, the auxiliary guide roller 55
Are rotatably supported by an auxiliary support member 61. The auxiliary support member 61 is fixed to the position above the main guide roller 53 by a bolt at a position shifted in the bending direction of the guide rail 51, and is positioned outside the guide rail 51 in the bending direction (right side in the drawing). The auxiliary guide roller 55 includes a cylindrical base 65 into which the auxiliary support member 61 is inserted into the inner diameter portion 63.
And donut-shaped guide plates 67 and 68 erected from both ends of the base 65 so as to face each other. The base 65 and the guide plates 67 and 68 are integrally formed.

When the main guide roller 53 is located near the upper end of the inclined portion 51b, the opposing surfaces 6 of the guide plates 67 and 68
The outer surfaces 71a, 71b of the oblique portion 51b located behind the guide surfaces 27a, 27b are fitted between 7a, 68a.
A slope 6 for guiding engagement with the guide rail 51 is provided on the peripheral edge of the opposing surfaces 67a, 68a of the guide plates 67, 68.
9 are formed.

Thus, when the window panel 3 is fully closed as shown in FIG.
3b is fitted between the guide surfaces 27a, 27b, and the outer surfaces 71a, 7 between the opposing surfaces 67a, 68a of the auxiliary guide roller 55.
1b is fitted, that is, the main guide roller 53 and the auxiliary guide roller 55 are both fitted with the guide rail 51.

Since the auxiliary guide roller 55 is displaced in the bending direction of the guide rail 51 above the main guide roller 53, when the main guide roller 53 is located in the vertical portion 51a, the auxiliary guide roller 55 is moved to the guide rail. 51. That is, at the position where the window panel 3 is lowered, only the main guide roller 53 is engaged with the guide rail 51.

Next, the operation will be described.

In the fully closed position of the window panel 3,
As shown in FIG. 2 and FIG.
The auxiliary guide roller 55 is fitted and supported by the outer surfaces 71a and 71b of the oblique portion 51b. Therefore, the support rigidity of the window panel 3 at the fully closed position can be secured mainly by the two guide rollers 53 and 55 and the guide rail 51. However, it goes without saying that the stabilizers 35 and 37 shown in FIG. 6 also contribute to the support rigidity.

Accordingly, the support rigidity of the window panel 3 at the fully closed position can be significantly improved by adding the auxiliary guide roller 55. For this reason, during high-speed running, the amount of glass sucked out is suppressed, the up / down driving of the window panel 3 can be performed without difficulty, and an increase in the size of the up / down driving device can be suppressed.

When the window panel 3 is in the fully closed position and the forces F1 and F2 act as shown in FIG. 7 and a rotational moment acts on the window panel 3, the window panel 3 is prevented from falling inward and the mounting accuracy is improved. The fully closed position is extremely stable.

Next, when the window panel 3 is lowered and opened, the auxiliary guide roller 55 is separated from the guide rail 51 and only the main guide roller 53 is moved up and down by the vertical portion 51a of the guide rail 51 as shown by the chain line in FIG. Will be done. In this way, the vertical trajectory of the window panel 3 is
The weather strip 38 and the stabilizer 3 shown in FIG.
5, 37 and the main guide roller 53 and the guide rail 51 in the present embodiment, so that the vertical movement of the window panel 3 can be smoothly performed.

At this time, the support rigidity of the window panel 3 is determined by the stabilizers 35 and 37, the main guide rollers 53 and the guide rails 51.
The span between 7 and the main guide roller 53 is sufficiently large, and sufficient supporting rigidity can be secured.

When the window panel 3 is returned to the fully closed position again, the auxiliary guide roller 55 is guided by the slope 69 to the outer surfaces 71a and 71b of the inclined portion 51b, and can smoothly shift to the above-mentioned support state. is there.

[0039]

As is apparent from the above, according to the structure of the present invention, the main guide roller is supported by the guide surface of the guide rail at the fully closed position of the window panel, and the auxiliary guide roller is supported by the outer surface of the guide rail. As a result, the support rigidity is remarkably improved, the elevation driving force can be reduced, the mounting accuracy at the fully closed position is improved, and the stable fully closed position can be obtained.

When the window panel is raised and lowered, the auxiliary guide roller is separated from the inclined portion, so that the same lifting operation as that without the auxiliary guide roller can be performed.
