Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a door glass guide device for raising and lowering a door glass, which is provided on a vehicle door or the like.

(Prior art) As a conventional door glass guide device, for example,
The device described in Publication No. 1-25562 (hereinafter referred to as No. 1)
A device described in Japanese Patent Publication No. 61-13078 (hereinafter referred to as a second conventional example) is known.

In the first conventional example, a door is provided with a sash, a guide groove is formed in the sash and is opened toward the outside of the vehicle, and a lifting guide provided on the door glass is slidably inserted into this guide groove. It has a structure.

Therefore, when the door glass is closed, the sash is covered with the door glass, making it difficult for unevenness to occur on the outer surface of the vehicle body, making it possible to create a flush surface.

The second conventional example is applied to a so-called sash-less door that does not have a sash, and rollers are provided at the front and rear of the lower part of the door glass to protrude in the front-rear direction and the outside direction of the vehicle, and there are four rollers inside the door that guide each roller. The structure is such that two guide rails are installed at the front and rear of the door glass, and two on the outside of the vehicle.

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

(Problems to be Solved by the Invention) However, since the device of the first conventional example has a sash, a sufficient sense of openness cannot be obtained when the door glass is opened. This becomes a particular problem when a vehicle has a body structure in which the roof is slidable or removable, and one of the doors is closed without the roof.

Furthermore, 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 car body is restricted. There were also problems.

On the other hand, in the second conventional example, although it does not have a sash and provides a sense of openness, it has a structure that only supports the lower part of the door glass, so the support rigidity is low (during high-speed driving). There are problems with wind leakage and watertightness, such as the door glass being sucked out of the vehicle.

Furthermore, when the door glass is swung, the door waist portion, which is the portion of the door where the door glass moves in and out, swings a lot, so the opening width of the door waist portion needs to be large. Therefore, there is a problem in that a large step is created between the door glass and the outer surface of the vehicle body, making it difficult to create a flush surface.

Furthermore, since the door glass is supported by a portion of the door glass that is always placed inside the door, it is not possible to provide a long support span in the vertical direction. In this way, with a structure that can only take a short span, even if you try to guide the door glass by twisting it in order to minimize the contact at the door waist part in order to solve the above problem, it will be difficult to control the amount of deflection and the accuracy will be poor. bad. Therefore, it is necessary to widen the width of the door waist part to absorb this error, and as expected,
Difficult to create a flash surface.

The present invention was developed by focusing on these conventional problems, and it is possible to obtain a wide feeling of openness when the door glass is opened, and also to obtain high support rigidity. It is an object of the present invention to provide a door glass guide device that can be guided with a small swing width in a door waist portion and can be made into a flush surface.

(Means for solving the problem) In order to achieve the above-mentioned object, the door glass guide device of the present invention is provided with a door on the side of the vehicle body, and the door has a door waist opening at the top of the door. A door glass that can be raised and lowered through the door waist portion is provided, and a door tower is provided at the rear end of the door and extends above the door waist portion, and the door tower has a rear end portion of the door glass. A glass overlapping part is provided whose outer surface is covered with a glass overlapping part, and an upper guide rail is provided in this glass overlapping part, and
A front lower guide rail and a rear lower guide rail are provided at the front inside the door and at the rear inside the door, and the upper guide is provided at the upper rear end of the door glass, the lower front end of the door glass, and the lower rear end of the door glass, respectively. A slider is provided that is guided by the rail, the front lower guide rail, and the rear lower guide rail, and each guide rail is formed in a shape that is displaced in the vehicle width direction so that it also moves in the vehicle width direction when the door glass is raised and lowered. The displacement amount of the upper guide rail and both lower guide rails in the vehicle width direction is appropriately adjusted according to the vertical position of the door glass.

(Function) In the door glass guide device of the present invention, when the door glass is closed, the upper guide rail, which is located above the door waist portion of the door, is covered with the door glass and is outside the door glass. Do not expose to

Moreover, since both the upper and lower parts of the door glass are supported by the upper guide rail and both lower guide rails, the door glass can be supported with high support rigidity.

On the other hand, when the door glass is opened, there is no sash at the top of the door glass, which creates a sense of openness.Especially in a structure where the roof above the door can be moved, the roof above the door can be completely opened. You can open it up and get a great sense of freedom.

Further, when raising and lowering the door glass, since the upper guide rail is provided at the glass overlapping part of the door tower, it is easy to make the shape of the door glass and the raising and lowering locus of the door glass different. In other words, in the case of Satsushi, the door glass is guided up and down along the shape of the door glass, but with the present invention, the difference between the shape of the door glass and the up and down locus can be absorbed on the door tower side, and the door with a cubic curved shape Glass guides are possible.

Furthermore, since the upper guide rail 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 of the part that supports the upper part of the door glass changes depending on the raising and lowering position of the door glass. By appropriately adjusting the amount of displacement in the vehicle width direction of the portion supporting the lower part, the door glass can be made to swing so that the position of the door glass relative to the door waist portion is always constant when the door glass is raised or lowered. . In this case, in the present invention, since the door glass is supported with a long support span in the vertical direction such as the upper and lower parts of the door glass, it is easy to control the amount of deflection. That is, since it is possible to make the amount of runout due to this error smaller than the error in the amount of displacement on the rail side, the amount of runout can be easily managed.

Therefore, even when a door glass having a cubic curved surface shape is raised and lowered, the amount of deflection of the door glass at the door waist portion during raising and lowering can be reduced, and the opening width of the door waist portion can be reduced.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

It is supported between 02 and 02.

As shown in FIG. 1, a door tower 12 is erected at the rear end of the door 1o, adjacent to the pillar 13 and extending above the waist portion 103.

A guard 104 is provided in the space 105 to prevent the door outer 101 from deforming toward the vehicle interior. Additionally, a weather strip 106 is provided on the door waist portion 103 to seal the outside of the vehicle and the space 105.
．． 107 (see FIG. 3).

As shown in FIG. 4, which is a sectional view taken along line IV-IV in FIG. 1, and FIG. 5, which is a sectional view taken along line V-V in FIG. 121 and a door tower inner panel (hereinafter referred to as tower inner panel) 12 arranged on the inside of the vehicle.

This tower outer 121 has a stepped portion 123 formed in the middle thereof, and a portion in front of this stepped portion 23 is a glass overlapping portion 1 disposed on the inside of the vehicle interior where the rear end portion of the door glass 11 is overlapped.
24, and the rear portion of the stepped portion 123 is an outer surface portion 12 that is disposed outside the vehicle interior and forms a part of the outer surface of the vehicle body.
It is said to be 5. The glass polymerization portion 124 is
A weather strip 126 is provided on the stepped portion 123 to seal the interior of the vehicle by being in pressure contact with the door glass 11.
2 is covered by the finisher 16.

Note that the outer surface portion 125 is located at the door glass 11 in the fully open position.
It is formed so that it is flush with the outer surface of.

The door glass 11 is formed into a cubic curved shape for reasons of design. And this door glass 11 is
As shown in FIG. 1, an upper guide rail 20 provided at the glass overlapping portion 124 of the door tower 12,
A front lower guide rail 21 provided at the front of the space 105 and a rear lower guide rail 22 provided at the rear of the space 105 guide the elevation. This is accomplished by the device 30.

Connecting rods 18 are erected toward the vehicle interior at three locations, at the front and rear of the lower part of the door glass 11 and at the rear of the upper part (see Fig. 1.3.4).

A spherical connecting portion 1 is provided at the tip of this connecting rod 18.
81 is formed, and this connecting portion 181 is connected to the slider 19 so as to be rotatable in all directions about one point. And this slider]9 is for each guide rail 2.
0 to 22 and are slid and guided.

The inner surface of the door glass 11 in the portion overlapping with the glass overlapping portion 124 is coated with black pudding 111 (see FIG. 4).

By the way, the door glass 11 is formed into a cubic curved shape, and in this embodiment, when the door glass 11 goes up and down, the weather strip 10 of the waist part 103
Between 6.107 and 107, the guide is designed to always pass through a constant position, that is, at this position, it is guided without swinging in the vehicle width direction.

For this reason, in this embodiment, each of the guide rails 20 to 22 is formed into a shape curved in the vehicle width direction, and furthermore,
The amount of curvature of the upper curved portion 201 of the upper guide rail 20 is larger than that of the upper curved portion 211.221 of both lower guide rails 21.22. In this way, the amount of displacement in the vehicle width direction is made different between the upper and lower parts of the door glass 11 depending on the elevation position, and as a result, the door glass 11 draws an elevation locus shown by arrow A in FIG. It is designed so that it does not swing in the vehicle width direction and does not interfere with the guard par 104.

Furthermore, when the door glass 11 is raised, it is raised in a trajectory opposite to the arrow Δ, and the upper end of the door glass 11 is moved toward the passenger compartment just before the fully closed position 11U as shown in the figure. 2, and is pressed against the weather strip 141, as shown in FIG.

In addition, u-1 to u-5 and L-1 to L-5 in FIG. 6 indicate the corresponding vertical positions of the upper guide rail 20 and both lower guide rails 21 and 22, respectively. Moreover, if the shape of the curved surface of the door glass 11 is different between the front and rear,
The amount of displacement in the vehicle width direction is made different between both lower guide rails 21 and 22, so that the door glass 1
By twisting the door glass 10, the amount of movement of the door glass 11 is different between the front and rear of the door glass 11, so that the waist portion 103 can be prevented from swinging.

To further explain the mounting structure of the upper guide rail 20, as shown in FIG.
A recess 127 is formed in the glass overlapping portion 124 , and the guide rail 20 is supported within this recess 127 .

The connecting rod 18 is inserted through a groove 151 formed in the finisher 15. Furthermore, the four parts 127 are formed to have a deeper depth toward the top, depending on the curvature of the guide rail 20. Further, a lip 152 is provided in the groove 151 of the finisher 15, and processing is performed so that the guide rail 20 is not visible when the door glass 11 is opened, thereby improving the appearance.

As shown in FIG. 4, a bracket 128 is attached to the tower inner 122 of the door tower 12, and the finisher 16 is attached to this bracket 128.

Further, as shown in FIG. 3, a glass-side stopper 23 is fastened together with the connecting rod 18 at the bottom of the door glass 11, and the door glass-side stopper 23 comes into contact with the door-side stopper 24 fixed to the door inner 102. 11 is restricted from rising at the fully open position.

Further, as shown in FIG. 5, a seat belt anchor bolt 25 is fixed to the upper end of the door tower 12, and a seat belt 26 is attached to this seat belt anchor bolt 25. Further, a hook 27 is fastened to the seat belt anchor 1 25, and when the door 10 is closed, the hook 27 engages with a striker 28 fixed to the pillar 13, so that the seat belt 26 It is designed to be able to resist the input of

In the door glass guide device of this embodiment configured as described above, since a sash is not provided above the door 10, when the door glass 11 is lowered with the lid 14 removed from the roof R, The upper part of the door 10 is completely opened and a large open feeling similar to that of a sash-less door can be obtained.

In addition, while providing a large open feeling similar to a sliding door, the door glass 11 is supported at two parts by the upper guide rail 20 and at the rear by the lower guide rails 21 and 22. This provides high support rigidity, which helps prevent wind leakage and improve watertightness during high-speed driving.

Furthermore, in this embodiment, in order to minimize the deflection in the vehicle width direction at the waist portion 103 when the door glass 11 is raised and lowered, this deflection is managed by increasing the support span between the upper and lower parts of the door glass 11. Therefore, the deflection error of the door glass 11 is small compared to the displacement error in the vehicle width direction in each of the guide rails 20 to 22, and the precision of this deflection management is high.

In addition, since the accuracy of the control of the deflection of the door glass 11 can be increased in this way, the error in the deflection amount can be absorbed in the waist portion 103. I can figure it out.

In addition, in the structure of this embodiment, since the upper guide rail 20 is provided in the glass overlapping part 124 that is covered by the rear end of the door glass 11, the upper guide rail 20 is not exposed to the outside of the vehicle. As shown in FIG.
25 can be easily formed on the same surface, and a flush surface can be easily achieved.

Moreover, since the upper guide rail 20 is provided in the door tower 12 having a box-like cross-sectional shape, the upper guide rail 20 may be curved in the vehicle width direction as shown in FIG. Even if the door glass 11 has a three-dimensionally curved surface, it can be easily accommodated by changing the cross-sectional shape of the door hoe 12, thereby making it possible to guide the door glass 11 having a cubic curved surface shape.

In addition, in the structure of the embodiment, in the door tower 12, when the door is closed, the seat belt anchor bolt 25 is
Since the seat belt 26 is connected to the vehicle body via the hook 27 and the striker 28, the support rigidity of the seat belt 26 is high.

Although the embodiments have been described above with reference to the drawings, the specific configuration of the present invention is not limited to the embodiments described above. For example, in the embodiment, the door glass was formed in a cubic curved shape, but Of course, it can be applied to door glass of any shape.

Further, in the embodiment, an example is shown in which a stepped portion and an outer surface portion are formed on the tower outer of the door tower, but the entire tower outer may be covered with door glass.

(Effects of the Invention) As explained above, in the door glass guide device of the present invention, since the door is not provided with a sash, a great sense of openness can be obtained when the door glass is opened. This effect is particularly noticeable in a structure in which the roof above the door can be moved.

Additionally, the upper guide rail supports the upper part of the door glass, and the lower part is supported by the front and rear lower guide rails, providing high support rigidity, preventing wind leaks and improving watertightness during high-speed driving. .

Furthermore, since an upper guide rail that supports the door glass above the door waist portion is provided at the glass overlapping portion of the door tower on the inside of the door glass, it is possible to guide the door glass having a next curved surface shape. This improves the degree of freedom in shaping the door glass and vehicle body shape.

In this way, the present invention has the advantages of a sash-less door in that it provides a large sense of openness and can improve the degree of freedom in shaping by making it possible to guide the door glass with a cubic curved surface up and down, and also provides a sash-less door that provides high support rigidity. This has the advantage that the following advantages can be obtained at the same time.

In addition, in the present invention, since the upper guide rail is provided between the door glass and the door tower, it is possible to easily create a flush surface in this area.

Furthermore, in the present invention, since the door glass is supported with a long support span in the vertical direction such as the upper and lower parts of the door glass, it is easy to control the amount of deflection when the door glass is raised and lowered. It is possible to reduce the amount of deflection in the door waist section when the door is opened, and to reduce the opening width of the door waist section. As a result, the opening width of the door waist portion can be made smaller and this area can be flushed out.
