Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass guide device provided in a vehicle door or the like for moving up and down a door glass.

(Prior Art) As a conventional door glass guide device, for example, Japanese Patent Publication No. 61
An apparatus described in Japanese Patent Publication No. 25562 (hereinafter referred to as a first conventional example) and an apparatus described in Japanese Patent Publication No. 61-13078 (hereinafter referred to as a second conventional example) are known.

In the first conventional example, a sash is provided on the door, and a guide groove is formed in the sash so as to open toward the vehicle exterior direction, and an elevating guide provided on the door glass is slidably inserted into the guide groove. It has a structure.

Therefore, when the door glass is closed, the sash is covered with the door glass and unevenness hardly occurs on the outer surface of the vehicle body, so that the flash surface can be achieved.

The second conventional example is applied to a so-called sashless door without a sash, and rollers are provided at the lower front and rear parts of the door glass so as to project in the front-rear direction and the vehicle exterior direction, and guide each roller inside the door. The structure is such that four guide rails are provided, two on the front and the rear of the door glass and on the outside of the vehicle.

Therefore, the inner guide rail and the outer guide rail can be offset, and the door glass can be raised and lowered while swinging.

(Problems to be Solved by the Invention) However, in the device of the first conventional example, since the sash is provided, a sufficient open feeling cannot be obtained when the door glass is opened. This becomes a particular problem in a vehicle having a vehicle body structure in which the roof is slidable or detachable, when the roof is not above the door.

Further, in the first conventional example, since the door glass is guided linearly by the sash, it is difficult to guide the door glass when it is formed into a cubic curved shape, and the shaping of the door glass and the vehicle body is restricted. There was also a problem.

On the other hand, in the second conventional example, it does not have a sash and thus has a wide open feeling, but since it has a structure in which only the lower part of the door glass is supported, the supporting rigidity is low, and the door is not operated at high speeds. Since the glass is sucked out of the car, there is a problem with wind leakage and water tightness.

Further, when swinging the door glass, the door waist portion, which is a portion through which the door glass of the door moves in and out, has a large amount of shake, so that a large opening width of the door waist portion is required. For this reason, there is a problem that a large step is generated between the door glass and the outer surface of the vehicle body, which makes it difficult to form a flash surface.

Further, since the door glass is supported by the portion of the door glass that is always disposed inside the door, the vertical support span cannot be long. In this way, with a structure that can only take a short span, even if you try to guide the door glass while twisting it to minimize the touch at the door waist to solve the above problem, it is difficult to control the shake amount and accuracy Is bad. Therefore, it is necessary to widen the width of the door waist part to absorb such an error.
It is difficult to make flash surface.

The present invention was made in view of such conventional problems, and it is possible to obtain a high support rigidity while obtaining a wide open feeling when the door glass is opened, and moreover, a door glass having a cubic curve is provided. It is an object of the present invention to provide a door glass guide device capable of guiding a flash surface with a small swing width in a door waist portion and enabling a flush surface.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the door glass guide device of the present invention, a door is provided on a side portion of the vehicle body, and this door has a door waist opened at an upper portion of the door. A door glass that can be raised and lowered through a portion is provided, and a door tower that extends above the door waist portion is provided upright at a rear end portion of the door, and a rear end portion of the door glass is provided at the door tower. A glass overlapping portion whose outer surface is covered by is provided, and an upper guide rail is provided in this glass overlapping portion,
The lower guide rail and the rear lower guide rail are provided in the front part of the door and the rear part of the door, and sliders slidably provided on the respective guide rails include a rear end upper part of the door glass and a lower front end part of the door glass. It is connected to the lower part of the rear end of the door glass via a connecting member, and one end or an intermediate part of this connecting member is provided with a connecting part capable of changing the relative angle with the slider. It is formed in a shape that is displaced in the vehicle width direction so that it also moves in the vehicle width direction when moving up and down. The means is adjusted so that the amount of displacement during passage is limited to less than a predetermined amount.

(Operation) In the door glass guide device of the present invention, when the door glass is closed, the upper guide rail located above the door waist portion of the door is covered with the door glass when the door glass is closed. Not exposed to.

Further, since the upper guide rail and both lower guide rails support both the upper part and the lower part of the door glass, the door glass can be supported with high supporting rigidity.

On the other hand, when the door glass is opened, there is no sash provided on the upper part of the door glass, so it has a high open feeling, especially in the structure where the roof above the door can be moved, the upper part of the door can be completely removed. You can get a big feeling of opening by opening.

In addition, since the upper guide rail is provided in the glass overlapping portion of the door tower when the door glass is moved up and down, it is easy to make the shape of the door glass and the ascending / descending trajectory of the door glass different. That is, in the case of the sash, the door glass is guided up and down along the shape of the door glass, but in the present invention, the difference between the shape of the door glass and the lifting trajectory can be absorbed on the door tower side, and the door glass A change in the relative angle with respect to the slider can be absorbed by a change in the angle at the connecting portion of the connecting member, and it is possible to guide the door glass having a cubic curved surface shape.

Furthermore, since the upper guide rails and both lower guide rails are formed in a shape that is displaced in the vehicle width direction, the amount of displacement in the vehicle width direction and the lower portion of the portion that supports the upper portion of the door glass depends on the vertical position of the door glass. By appropriately adjusting the amount of displacement in the vehicle width direction of the portion supporting the door glass, the door glass can be swung so that the position of the door glass with respect to the door waist portion is always constant when the door glass is moved up and down. In this case, in the present invention, since the support span of the door glass is long in the vertical direction such as the upper part and the lower part of the door glass, it is easy to manage the shake amount. That is, since the shake amount due to this error can be made smaller than the error of the displacement amount on the rail side, the shake amount can be easily managed.

Therefore, even when the door glass having the cubic curved shape is moved up and down, it is possible to reduce the amount of swinging of the door glass at the door waist portion when the door glass is moved up and down, and to reduce the opening width of the door waist portion.

(Examples) Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a side view showing a door 10 to which a door glass guide device of one embodiment of the present invention is applied.

This tower outer 121
Is formed with a step portion 123 in the middle, and a portion on the entire side of the step portion 123 is a glass overlap portion 124 which is arranged inside the vehicle compartment and where the rear end of the door glass 11 is overlapped. The rear side portion is an outer surface portion 125 that is arranged outside the vehicle compartment and forms a part of the outer surface of the vehicle body. The glass overlap portion 124 is covered with a finisher 15, and the step portion 123 is provided with a weather strip 126 that is in pressure contact with the door glass 11 to seal the passenger compartment, and the tower inner 122 has a finisher. It is covered with 16.

The outer surface portion 125 is formed so as to be flush with the outer surface of the door glass 11 at the fully closed position.

The door glass 11 is formed into a cubic curved surface shape for reasons of modeling. And this door glass 11 is the first
As shown in the figure, the glass overlap part 124 of the door tower 12

Incidentally, the door glass 11 of the overlapping portion of the glass overlapping portion 124
Has a black surface print 111 on its inner surface (see FIG. 4).

By the way, although the door glass 11 is formed in a cubic curved surface shape, in this embodiment, when the door glass 11 moves up and down, the weather strips 106 and 107 of the waist portion 103 always pass through a fixed position. Thus, in other words, at this position, the vehicle is guided without swinging in the vehicle width direction.

For this reason, in the present embodiment, the guide rails 20 to 22 are each formed in a shape curved in the vehicle width direction, and the bending amount thereof is larger than the bending amounts of the upper bending portions 211 and 221 of the lower guide rails 21 and 22. Also, the bending amount of the upper bending portion 201 of the upper guide rail 20 is larger. In this way, the amount of displacement in the vehicle width direction is made different between the upper part and the lower part of the door glass 11 depending on the ascending / descending position, whereby the door glass 11 draws the ascending / descending trajectory shown by the arrow A in FIG. It does not swing in the vehicle width direction and does not interfere with the guard bar 104.

When the door glass 11 is lifted, the door glass 11 is lifted in a trajectory opposite to the direction of the arrow A, and the upper end of the door glass 11 moves toward the passenger compartment immediately before the fully closed position 11U as shown in the figure. As shown in Fig. 2, the weather strip
141 is pressed.

It should be noted that u-1 to u-5 and L-1 to L-5 in FIG. 6 indicate the corresponding elevated positions of the upper guide rail 20 and the lower guide rails 21 and 22, respectively. Also door glass
If the curved surface shape is different even for 11 front and rear, the displacement amount in the vehicle width direction is made different between the two lower guide rails 21, 22 so that the door glass 11 is twisted when moving up and down, However, the amount of movement can be changed so that the waist portion 103 does not shake.

Further explaining the mounting structure of the upper guide rail 20, as shown in FIG. 4, a concave portion 127 is formed in the glass overlapping portion 124 of the door tower 12, and the concave portion 127 is formed.
