Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an improvement in an automobile door device.

(Prior Art) In order to reduce air resistance, recent automobiles are designed to have flush surfaces, that is, to eliminate steps on the outer surface of the vehicle body so that the outer surface of the vehicle body is as flush as possible. As a part of this flush surface design, there is a door glass that is installed at the top of the door panel and positioned further outside the vehicle than the door sash (US Pat. No. 424).
0227 specification).

In this way, when the door glass is placed on the outside of the door, a weather strip is attached to the door sash and applied to (the periphery of) the door glass in order to create a seal between the door sash and the door glass. I try to make them come into contact with each other. Further, in order to smoothly raise and lower the door glass and to prevent it from wobbling, a guide block provided on the door glass is guided by a door sash.

Conventionally, since the door glass is guided by the door sash using the guide block, the lift line of the door glass is set to directly follow either the front or rear side edge of the door sash where the guide block is guided. It had been.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional device, if the space between the door glass and the door sash is sealed with a weather strip when fully closed, the door glass Because the door is always raised and lowered in strong contact with the weatherstrip, the braking action of the weatherstrip may move, making it difficult to raise and lower the door glass smoothly, and the weatherstrip may be easily damaged by the door glass. there were.

Therefore, an object of the present invention is to use a guide block to guide the door glass up and down by the door sash, and a weather strip to seal between the door glass and the door sash when the door sash is fully closed. To provide a door device for a motor vehicle which allows a door to be smoothly raised and lowered without being hindered by a weather strip, and which prevents the weather strip from being damaged due to the raising and lowering.

(Means for Solving Problems 1 Effect) To achieve the above-mentioned object 1 In the present invention, basically, the setting direction of the ascending and descending line of the door glass is devised so that the door glass descends. As the door glass moves away from the weather strip. Specifically, in an automobile door in which a door glass that is raised and lowered is located on the outside of the vehicle of a door sash provided at the upper part of the door panel, the door sash is such that the distance between its front edge and rear edge is downward. It is set to become wider as it goes.

Each of the door sashes extends substantially parallel to the door glass, and has an outer flange portion located on the outside in the direction of the plate surface of the door glass, and an inner flange portion located on the inside, and the outer flange portion includes: A weather strip is attached to the door glass when it is fully closed, and a guide rail is attached to the inner flange portion, and a weather strip is attached to the door glass on either the front or rear side edge side of the door sash. A guide block is attached to the guide rail so as to be slidably displaceable in the longitudinal direction and the width direction, and the elevating line is aligned with a reference line along the inner flange portion on the one side edge side. On the other hand, as it descends, it is set to be slightly inclined toward the other side (IllJll) of the door sash.

This is the configuration.

With this configuration, as the door glass is lowered from the fully closed state where it is sealed to the door sash by the weather strip, the door glass moves away from the weather strip, so that it is not obstructed by the weather strip. The door glass can be raised and lowered smoothly without any friction, and the weather strip is prevented from being damaged by the door glass. In addition, the guide block can slide and displace not only in the longitudinal direction but also in the width direction with respect to the guide rail, so it can absorb changes in the relative position with respect to the guide rail that occur due to changes in the vertical position of the door glass. , the door glass is always raised and lowered without rattling. Of course,
Even if the door glass slightly displaces toward the side edge opposite to the side edge of the door sash that forms the reference line as it descends, the distance between the front and rear edges of the door sash will decrease downward. Since the door glass gradually becomes wider, a situation in which the door glass is raised or lowered while making strong contact with the weather strip on the opposite side edge does not occur.

(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a car A is a two-door type, and the door 1 has a door sash 3 integrally provided on the upper part of a door panel 2, and the door sash 3 is provided on the outside of the vehicle, as shown in FIG. A door glass 4 is positioned there. As a result, when the door glass 4 is closed (in the highest position), the door glass 4 is almost flush with the roof panel 5, front pillar 6, and rear pillar (center pillar) 7 of the automobile A without any difference in level. On the other hand, the upper edge 2a of the door panel 2 is connected to the door glass 4.
It is formed so that it continues smoothly toward the board surface, creating a flush surface.

As shown in FIG. 2, the door sash 3 has a rear edge 3A that extends in a substantially vertical direction, and a front edge 3B that is strongly sloped toward the rear as it goes upward in accordance with the slope of the front pillar 6. and an upper edge 3C that connects the upper ends of the front and rear side edges 3A and 3B.In this way, from the inclination relationship between the both side edges 3A and 3B, the both side edges The distance between 3A and 3B is set to become wider as it goes downward. A guide block 11 that is slidably engaged with the rear edge 3A of the door sash 3 is integrated into the door glass 4, so that the door glass 4 can be opened and closed (raised and lowered) smoothly without rattling. Ru.

Next, the relationship between the door sash 3 and the door glass 4 will be explained in detail with reference to FIGS. 5 and 6. First, door satush 3
a flange portion 21 extending substantially parallel to the door glass 4;
The flange portion 21 has an intermediate rib portion 22 extending substantially perpendicularly toward the vehicle interior from the intermediate portion of the flange portion 21, and the portion outside the intermediate rib portion 22 of the flange portion 21 (outside in the direction of the plate surface of the door glass 4) is an outer flange. portion 21a, and intermediate rib portion 22
The inner side portion is an inner flange portion 21b.

From the inner end of the intermediate rib portion 22, a closed-section support portion 23 is connected to the inner flange portion 21b and is bent so as to be substantially parallel to the inner flange portion 21b. The portion is a locking portion 23a that extends short toward the inner flange portion 21b. Further, a U-shaped locking portion 24 that opens toward the outer flange portion 21a is formed near the inner end of the intermediate rib portion 22. In the embodiment, such a door sash 3 is constructed by, for example, roll-forming a single metal plate such as aluminum or iron plate.

A guide rail 31 made of synthetic resin or the like having a small coefficient of friction is fitted into the inner flange portion 21b of the door sash 3. The guide rail 31 includes a mounting portion 32 that is approximately U-shaped and is fitted into the inner flange portion 21b;
The mounting portion 32 includes a lip portion 33 protruding from the outside of the vehicle toward the door glass 4.
reinforced by.

The guide block 11 is located at the upper rear end of the door glass 4.
are integrated. That is, the guide block 11 has a cross section FIl! It has a U-shape and fits so as to cover the mounting part 32 of the guide rail 31, and the door glass 4
The outer surface of the tip 11a extends substantially parallel to the plate surface of the
It is configured to slide on a guide surface 32a that is the inside surface of the mounting portion 32. Then, when the door glass 4 is pressed toward the outside of the vehicle by the lip portion 33 of the guide rail 31 described above, the tip portion 11a is moved to the mounting portion 32.
It is designed to be in constant contact with the guide surface 32a without wobbling. Of course, as is already clear from the above description, this guide block 11 is fitted to the guide rail 31 so that it can be displaced in the longitudinal direction and width direction (vertical direction in FIG. 5) of the guide rail 31. .

On the other hand, a garnish 41 is provided on the inner peripheral surface side of the door sash 3.
is arranged, and the locking part 41a is a locking part 23a formed on the guide rail 31 and the pillar part 23 of the door sash 3.
It is fixed to the door sash 3 using the. With such a garnish 41, the inner surface of the door sash 3 in the direction of the surface of the door glass 4 and the guide block 11 are almost entirely covered, making it possible to keep an eye on the vehicle from inside the vehicle.

A seal member 51 is fitted onto the outer flange portion 21a of the door sash 3. This seal member 51 serves as both a weather strip 61 and a door seal 42, and has a mounting portion 52 for the outer flange portion 21a.
A weather strip 61 is provided on the outer side of the vehicle, and a door seal 42 is provided on the inner side of the vehicle from the mounting portion 52. A core metal 53 is embedded in the mounting portion 52 in a U-shape so as to cover the outer flange portion 21a, thereby reinforcing the mounting portion 52.

The weather strip 61 has a thin portion 62 and a thick portion 6 from the inside to the outside in a portion facing the outer end surface of the door glass 4.
3, and has a fiS1 lip portion 64 that extends outward from the door glass 4 at its tip end. This first lip portion 64 is closed when the door glass 4 is in the closed position.

When the outer end surface of the door glass 4 comes into contact with the thin wall portion 62, it is bent toward the inside of the vehicle and comes into contact with (seals) the outer surface of the door glass 4 (see FIG. 5). , and from the thick portion 63, the second lip portion 6
This second lip portion 65 provides a seal between the door sash 3 and the vehicle body 43.

The door seal 42 is hollow and easily deformable, and is attached to the door sash 3 and the vehicle body 4 on the inside of the vehicle from the second lip portion 65 formed on the weather strip 61.
It serves as a seal between 3 and 3. Further, this door seal 42 also utilizes the locking portion 24 of the door sash 3 to ensure its mounting strength. Of course, this door seal 42 may be formed separately from the weather strip 61.

Here, the door glass 4 is raised and lowered guided by a guide mechanism 44 shown in FIG. The rear upper end of a certain door glass 4 is indicated by an X. Additionally, a door sash 3 that slides and guides the guide block 11 is provided.
The rear edge 3A has the same cross-sectional shape over its entire length in the longitudinal direction (this also applies to the guide rail 31 and Weathermetry 2 Pro 1), and its reference line β
are shown by dashed lines in FIGS. 2 to 4. In view of the setting of the same cross-sectional shape described above, in the present invention, this reference line β is the same as long as it passes through a predetermined cross-sectional position of the rear edge 3A, but as shown in FIGS. Here, it is depicted as passing through the rear upper end X of the door glass 4 in the closed position (the highest position). The above-mentioned elevation line α is located at the front side of the reference line β as it goes downward, that is, the front edge 3 of the door sash 3.
It is slightly inclined toward the A side, and the angle of inclination made by both lines α and β is assumed to be 0.

In the above configuration, when the door glass 4 is in the closed position, the seal between the door sash 3 and the door glass 4 is formed by the first lip portion 64 and the thin wall portion, as shown in FIGS. 4 and 5. 62 and the lip portion 33 of the guide rail 31, the structure is substantially triple-layered. Further, the seal between the door sash 3 and the vehicle body 43 is formed by a second lip portion 6.
5 and the door seal 42.

Here, when the door glass 4 is lowered as shown in FIG. 3, the slope of the door glass 4 is lowered as shown in FIGS. The end surface 4a is separated from the weather strip 61. That is, the rear end surface 4a of the door glass 4 is formed so as to be parallel to the reference line β, but as the door glass 4 descends along the elevation line α, as is clear from FIG. As such, this rear end surface 4a is separated from the reference line β, that is, the weather strip 61 (the amount of offset away from the reference line β at this time is shown in the text in FIG. 4). This prevents the door glass 4 (rear end surface 4a) from sliding in strong contact with the weather strip 61 when the door glass 4 moves up and down.
The weather strip 61 can be smoothly raised and lowered, and damage to the weather strip 61 can be prevented. Of course, the door glass 4 is slightly displaced forward as it descends, but due to the setting of the distance between the side edges 3A and 3B of the door sash 3, the door glass 4 may be displaced slightly forward as it descends. Since it also moves away from the weather strip 61 on the front edge 3B side, there is no similar problem. Further, although the depth at which the guide block 11 fits into the guide rail 31 changes depending on the elevation of the door glass 4 described above (the fifth
6), the fitted state with respect to the guide rail 31 is always maintained, and the door glass 4 is always raised and lowered without wobbling.

Although the embodiment has been described above, the door glass 4 may be moved up and down along the front edge 3B of the door sash 3 as necessary. Of course, in this case, the elevation line α is slightly inclined toward the rear edge 3A as it goes downward with respect to the reference line β of the front edge 3B, and the guide block 11 is tilted toward the rear edge 3A. It is sufficient to fit the guide rail 31, and in the case of a four-door type vehicle such as a sedan, it can be similarly applied to the rear door.

(Effects of the Invention) As is clear from the above description, the present invention is capable of sealing between the door glass and the door sash using a weather strip when the door glass is fully closed; Since the weather strip is prevented from strongly contacting the door glass when the door glass is raised and lowered, the door glass can be raised and lowered smoothly, and damage to the weather strip itself can be prevented.

Of course, the guide block is always maintained in a fitted relationship with the guide rail of the door sash, thereby preventing rattling when the door glass is moved up and down.

In particular, the side edge of the door that guides the guide block can be set to have the same cross-sectional shape over its entire length in the longitudinal direction, except for design requests. It will be advantageous.
