Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window panel raising / lowering device for raising / lowering a freely movable window panel of an automobile door.

[0002]

2. Description of the Related Art As a conventional window panel raising / lowering device, for example, there is one as shown in FIG. 5 (a new model manual "Introduction of R10 type car" issued by Nissan Motor Co., Ltd. June 1990 D- 40). FIG. 5 shows a front door 1 of, for example, a four-door hardtop as an automobile door as seen from the inside of the vehicle, with the lifting device 5 of a window panel 3 seen through. The window panel 3 is supported so as to be movable up and down with respect to the door panel 7. Inside the door panel 7, a lift drive device 9 for driving the window panel 3 up and down is provided.

The elevator drive device 9 includes 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.

Therefore, 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 vertically extending portion 23a arranged along the vertical direction of the door panel 7,
The slanting portion 23b is formed continuously from the upper end portion 23c of the vertically extending portion 23a and is bent toward the door opening side (left side of the drawing) in the door width direction. The inclined portion 23b is provided to avoid the door lock 10 attached to the door opening side of the door panel 7 and dispose the guide rail 23. A guide roller 25 supported by the lower portion of the window panel 3 is guided up and down with respect to the guide rail 23.

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 in FIG.

As shown in FIG. 6, the guide rail 23 has a channel-shaped cross section, and has rolling surfaces 26a and 26b facing each other in the door width direction (direction orthogonal to the paper surface) and a door thickness direction (left and right direction in the paper surface). The guide surface 27a facing the
27b and. These rolling surfaces 26a, 27
Both b and the guide surfaces 17a and 27b are continuously formed from the vertically extending portion 23a to the obliquely extending portion 23b. The guide rail 23 includes an upper bracket 29a and a lower bracket 29.
It is attached to the door inner panel 31 of the door panel 7 by b.

A peripheral surface 25a of the guide roller 25 is guided by rolling surfaces 26a and 26b, and a side surface 25 is formed.
b is opposed to the guide surfaces 27a and 27b. The guide roller 25 is supported by a pivot 33a of a support member 33 provided at the bottom of the window panel.

Therefore, when the window panel 3 is driven up and down, the guide roller 25 is guided up and down by the vertically extending portion 23a and the inclined portion 23b of the guide rail 23.

In FIG. 6, 35 is an inner stabilizer and 37 is 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 a door molding 4 attached to a door outer panel 41
It is provided in 3. The stabilizers 35 and 37 guide the window panel 3 in sliding contact. 45 is a door trim.

With the above structure, the window drive 3 can be moved up and down with respect to the door panel 7 by the elevator drive device 9, the guide roller 25 is guided by the guide rail 23, and the stabilizer 3 is provided.
The window panel 3 is supported by sliding contact with 5, 37.
Can be smoothly moved up and down along a predetermined locus.

FIG. 7 shows a stopper that determines 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 shown.
The second stopper 49 is provided on the first 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]

In the structure described above, when the window panel 3 is raised to the fully closed position, the guide roller 25 and the stabilizers 35 and 37 are arranged as shown in FIG. 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 amount of suction of the window panel 3 due to the difference in air pressure inside and outside the vehicle during high-speed traveling becomes large, and the elevation drive force based on the displacement of the window panel 3 increases significantly, and a large elevation drive device is required. There was a problem of becoming.

Further, as described above, there is a possibility that the window panel 3 may be displaced in the vehicle width direction even when it is not traveling at high speed, when the window panel 3 is in a fully closed state. That is, as shown in FIG. 7, since the first stopper 47 abuts on the second stopper 49, a downward force F1 acts between the stoppers 47 and 49, and the downward force F1 acts between the guide channel 19 and the main arm 15. Force F2 works. Then, due to these forces F1 and F2, a rotational moment to the inside of the vehicle acts on the window panel 3 and the window panel 3 tilts inward, causing a problem that the fully closed position of the window panel 3 is not stable.

Here, regarding the support rigidity of the window panel 3, a plurality of guide rollers 25 are provided and
It can be increased by increasing the number of supporting points.

However, if a plurality of guide rollers 25 are provided on the guide rail 23 having the inclined 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 lifting drive device 9 blocks the rotation of the window panel 3, the window panel 3 cannot actually be lifted.

Therefore, an object of the present invention is to provide a window panel elevating device capable of enhancing the support rigidity of the window panel 3 at the fully closed position with a simple structure.

[0018]

According to the present invention, a window panel which can be raised and lowered with respect to a door panel, a lift drive device for driving the window panel up and down, and a lift panel arranged inside the door panel are provided along the vertical direction of the door panel. It is composed of a vertically extending portion and an obliquely extending portion which is formed continuously from the upper end of the vertically extending portion and is bent in the door width direction. A guide surface facing the door thickness direction is formed continuously from the vertically extending portion to the obliquely extending portion. A main guide roller that is supported by the lower end of the window panel, is fitted between guide surfaces of the guide rail, and is vertically guided along the guide rail; and a door above the main guide roller. An auxiliary guide roller that is offset by the width direction and is supported by the window panel and that fits on the outer surface of the oblique portion at least at the 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 to the guide surface of the guide rail, and the auxiliary guide roller is fitted to the outer surface of the oblique portion. Therefore, the window panel is supported at the two locations of the main guide roller and the auxiliary guide roller, and the support rigidity thereof is significantly improved. When the window panel descends and the main guide roller reaches the vertically extending portion, the auxiliary guide roller is separated from the guide rail, and only the main guide roller is vertically guided by the vertically extending portion of the guide rail to support the single location. Smooth guidance of the window panel by the guide can be achieved.

When the window panel again moves from the fully open position to the fully closed position, the window panel is lifted by the guide of only the main guide roller until the main guide roller moves to the inclined portion. Then, at the fully closed position after the main guide roller is moved to the obliquely installed portion, the auxiliary guide roller is fitted to the outer surface of the obliquely installed portion of the guide rail, so that stable support can be performed at the fully closed position.

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 raising / lowering device according to an embodiment of the present invention is applied, as seen from the inside of the vehicle compartment. This FIG. 1 is a view corresponding to FIG. 5, and the same components as those in FIG.

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

A main guide roller 53 is supported on 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 structure 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 positioned on the obliquely installed portion 51b, FIG. 3 is a sectional view taken along the line III--III of FIG. 2, and FIG. 4 is a guide rail 51 and a main guide roller 53. The positional relationship of the auxiliary guide roller 55 is shown.

As shown in FIG. 2, the guide rail 51 has a channel-shaped cross section, and has rolling surfaces 26a, 26b and guide surfaces 27a, 27b continuous from the vertically extending portion 51a to the obliquely extending portion 51b. ing. This rolling surface 26
The a, 26b and the guide surfaces 27a, 27b have the same structure as that of FIG.

The peripheral surface 53a of the main guide roller 53 is guided by the rolling surfaces 26a and 26b, and the 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 the auxiliary support member 61. The auxiliary support member 61 is fixed to the upper side of the main guide roller 53 by bolting at a position displaced in the bending direction of the guide rail 51, and is located outside the bending direction of the guide rail 51 (right side of the drawing). The auxiliary guide roller 55 has a cylindrical base portion 65 into which the auxiliary support member 61 is inserted in the inner diameter portion 63.
And donut disc-shaped guide plates 67 and 68 which are erected opposite to each other from both ends of the base portion 65, and the base portion 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 facing surfaces 6 of the guide plates 67 and 68 are opposed to each other.
The outer surfaces 71a and 71b of the slanted portion 51b located on the back side of the guide surfaces 27a and 27b are fitted between the 7a and 68a.
Slopes 6 for guiding fitting with the guide rail 51 are provided at the peripheral portions of the facing surfaces 67a, 68a of the guide plates 67, 68.
9 is formed.

As a result, as shown in FIG. 4, the side surface 5 of the main guide roller 53 is in the fully closed position of the window panel 3.
3b is fitted between the guide surfaces 27a and 27b, and the outer surfaces 71a and 7b are disposed between the facing surfaces 67a and 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 to the guide rail 51.

Further, since the auxiliary guide roller 55 is displaced above the main guide roller 53 in the bending direction of the guide rail 51, when the main guide roller 53 is located on the vertical portion 51a, the auxiliary guide roller 55 is guided by the guide rail. It becomes a state away from 51. That is, at the position where the window panel 3 is lowered, only the main guide roller 53 is fitted with the guide rail 51.

Next, the operation will be described.

At the fully closed position of the window panel 3,
As shown in FIGS. 2 and 3, the main guide roller 53 has the guide surface 27.
The auxiliary guide rollers 55 are fitted and supported on the outer surfaces 71a and 71b of the inclined portion 51b. Therefore, the supporting rigidity of the window panel 3 at the fully closed position can be ensured mainly by the guide rollers 53, 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.

Therefore, the supporting rigidity of the window panel 3 at the fully closed position can be significantly improved by adding the auxiliary guide roller 55. Therefore, the amount of glass sucked out is suppressed during high-speed traveling, the window panel 3 can be lifted and lowered without difficulty, and the increase or decrease in size of the lift driving device can be suppressed.

Further, when the window panel 3 is in the fully closed position, even if the forces F1 and F2 act and the rotational moment acts as shown in FIG. 7, the inward tilting of the window panel 3 is suppressed and the construction 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 separates from the guide rail 51 and only the main guide roller 53 moves up and down to the vertical portion 51a of the guide rail 51 as shown by the chain line in FIG. Will be done. In this way, the ascending / descending trajectory of the window panel 3
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, the window panel 3 can be smoothly moved up and down.

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

When the window panel 3 is brought to the fully closed position again, the auxiliary guide roller 55 is guided by the inclined surface 69 to the outer surfaces 71a and 71b of the inclined portion 51b, so that the supporting state can be smoothly changed. is there.

[0039]

As is apparent from the above, according to the configuration of the present invention, the main guide roller is supported by the guide surface of the guide rail and the auxiliary guide roller is supported by the outer surface of the guide rail at the fully closed position of the window panel. As a result, the supporting rigidity is remarkably improved, the lifting drive force can be reduced, and the construction accuracy at the fully closed position is improved, and the stable fully closed position can be achieved.

When the window panel is moved up and down, the auxiliary guide roller is separated from the obliquely installed portion, so that the same lifting operation as that without the auxiliary guide roller can be performed.
