Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass support structure for a vehicle door.

[0002]

2. Description of the Related Art As a conventional door glass support structure for a vehicle door, for example, those shown in FIGS. 4 to 6 are known (for a similar technique, see Japanese Utility Model Laid-Open No. 63-161019). Hereinafter, in the drawings, A indicates the front side, B indicates the rear side, C indicates the outside, and D indicates the inside.

Reference numeral 1 is a front door of an automobile, which is attached to a side portion of a vehicle body in the front-rear direction. This door 1
Is formed by combining the inner panel 2 and the outer panel 3, and a sash portion 5 for supporting the lifted door glass 4 is formed on the upper portion thereof, and a door body 6 for housing the lowered door glass 4 is formed on the lower portion thereof. ing. An X-arm type regulator 7 for vertically moving the door glass 4 and a rail 9 for slidably guiding a guide roller 8 fixed to the door glass 4 are provided in the door body 6.

The door glass 4 is adapted to move vertically between the door body 6 and the sash portion 5 via a waist opening 10 formed at the upper end of the door body 6. The waist opening 10 is provided with a pair of weather strips 11 as "sealing members", and the weather strips 11 slidably sandwich and support the door glass 4 (Fig. Weather strip 11 in 5
The line shown as indicates the position where the weather strip 11 is sandwiched between the inner and outer weather strips 11). In addition, there is a joint flange 12 protruding toward the center of the opening of the sash portion 5, and the joint flange 12 has a glass run 1 as a “seal member”.
3 is attached.

Next, the relationship between the door glass 4 and the glass run 13 will be described with reference to FIG. The door glass 4 has a front edge portion 14, an upper edge portion 15 (oblique edge portion 16 + top edge portion 17), a rear edge portion 18, and a lower edge portion 19 at the peripheral edge thereof. The door glass 4 has a curved shape so as to bulge outward in the front-rear direction and the up-down direction, for the reason of modeling. That is, in FIG. 5, a curved line in which the front edge portion 14 and the rear edge portion 18 match the ascending / descending locus of the door glass 4 with respect to the flat virtual door glass 4 ′ shown by the imaginary line (two-dot chain line) It is formed along L ₁ , and the lower edge portion 19 is formed along a curved line L ₂ in the front-rear direction. The upper edge portion 15 is also originally formed along the curve line L ₂ in the front-rear direction, but the front end 15 of the upper edge portion 15 is also formed.
It is inclined inward from a polygonal line α connecting a and the rear end 15b, and a corner portion K which is a boundary point between the beveled edge portion 16 and the top edge portion 17 is made to coincide with the virtual door glass 4 ′.

On the other hand, the glass run 13 provided on the sash portion 5 includes a front edge corresponding portion 20 corresponding to the door glass 4, an upper edge corresponding portion 21 (a slanted edge corresponding portion 22 + a top edge corresponding portion 2).
3), it has a rear end corresponding portion 24. Also, the glass run 13 (joint flange 12) and the weather strip 11 (waist opening 10) are also imaginary lines (two-dot chain lines).
The flat virtual glass run 13 ′ and the weather strip 11 ′ shown in FIG. 3 are curved so as to correspond to the door glass 4. That is, grass run 13
The front edge corresponding portion 20 and the rear edge corresponding portion 24 are formed along the curved line L ₁ in the vertical direction. Also, grass run 1
The upper edge corresponding part 21 of 3 and the weather strip 11 (waist opening 10) are formed along the curve line L ₂ in the front-back direction. The curved line L ₂ in the front-rear direction is the front end 15a and the rear end 15b of the upper edge portion 15 when viewed in the direction along the degree of bending of the door glass 4 in the vertical direction (curved line L ₁ ). It is in a state of being matched with each other and bulging outward at the middle portion.

As described above, since the door glass 4 has the upper edge portion 15 tilted inward from the polygonal line α, the door glass 4
The corner K in the middle position of the upper edge 15 of the glass run 1
It is located relatively inward with respect to the upper edge corresponding portion 21 of No. 3, and is in a state of being sufficiently adhered to the lip portion 13a of the glass run 13. The corner K at the middle position of the upper edge 15 of the door glass 4 is thus inwardly brought into close contact with the glass run 13 because the outer surface of the door glass 4 becomes a negative pressure when the vehicle runs at high speed. , The door glass 4
Since a phenomenon occurs in which the middle portion (corner K) of the above is sucked out by a predetermined amount d (the door glass after 4a moves to the outside in the figure), the door glass 4 moves to the outside in this way. Also, the position of the intermediate portion (corner K) of the upper edge portion 15 of the door glass 4 is preset inward so that the close contact with the grass run 13 is ensured.

[0008]

However, in such a conventional technique, in order to secure the adhesion between the door glass 4 and the glass run 13 during high speed traveling,
Since the door glass 4 has a special shape in which the upper edge portion 15 of the door glass 4 is folded inward from the polygonal line α, the manufacturing of the door glass 4 itself becomes complicated, which is very disadvantageous in terms of manufacturing efficiency and cost.

As another measure against the inner edge of the upper edge 15 of the door glass 4, instead of forming the door glass 4 into the special shape as described above, a large guide portion 25 (hatched in FIG. 6) is provided on the glass run 13. It is conceivable to form a part). That is, an inclined surface 25a having a constant angle θ with respect to the door glass 4 is formed on the guide portion 25.
The upper edge portion 15 of the door glass 4 is abutted against 5a, and the upper edge portion 1
5 is a means for moving the inside 5, but if such a large guide portion 25 is provided, the guide portion 25 largely projects to the outside, which is very disadvantageous in terms of appearance this time.

The present invention has been made by paying attention to such a conventional technique, and the door glass can be formed without inclining the upper edge portion of the door glass inward or forming a guide portion on the glass run. The present invention provides a door glass support structure for a vehicle door, the upper edge of which can be set to the inner side.

[0011]

In order to achieve the above object, a door glass support structure for a vehicle door according to the present invention has a structure in which upper and lower edge portions of a door glass and a seal member at a waist opening are arranged in a front-rear direction. The seal member of the vehicle body or the sash portion, which is formed linearly along the upper edge portion, is aligned with the front edge and the rear edge of the upper edge portion when viewed in the direction along the vertical bending degree of the door glass. In addition, it is formed along a curve line in the front-back direction that is in a state of bulging outward.

Here, the "seal member for the vehicle body or the sash portion" means that in the case of a sashless door, the seal member is attached to the door opening edge portion of the vehicle body, and in the case of a door with sash, the seal member is This is because it can be attached to the sash part of the door.

Further, "when viewed in a direction along the degree of vertical bending of the door glass" is mentioned, but depending on the door glass, the degree of bending in the vertical direction may be "0", that is, it may be flat in the vertical direction. In the case of such a flat door glass, it will be viewed in the direction along the vertical direction of the door glass (or the tilt direction when tilted).

[0014]

The upper edge portion of the door glass is formed linearly, whereas the seal member of the vehicle body or the sash portion conforms to the front and rear ends of the upper edge portion and has a curved line in the front-back direction that bulges outward. Since it is formed along, the middle portion of the upper edge portion of the door glass is relatively inward with respect to the corresponding seal member. Therefore, the adhesion of the door glass to the seal member is enhanced, and the adhesion of the door glass and the seal member can be ensured even when traveling at high speed.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted.

1 and 2 are views showing an embodiment of the present invention. In the door glass 26 according to this embodiment, the front edge portion 27 and the rear edge portion 28 are formed along the curved line L ₁ bulging outward corresponding to the vertical ascending / descending trajectory as in the conventional case, but the upper edge portion 29 (oblique edge portion 30 + top edge portion 31) and the lower edge portion 32 are each linearly formed along the front-rear direction.
That is, the door glass 26 of this embodiment has a shape in which a flat virtual door glass 26 'is curved only in the vertical direction.

On the other hand, in the glass run 13 as the "seal member", the upper edge corresponding portion 21 is formed along the curve line L ₂ in the front-rear direction as in the conventional case (the glass run 1).
The joint flange 12 for mounting 3 is naturally curved).
The curve line L ₂ in the front-back direction is the degree of curvature of the door glass 26 in the vertical direction (curve line L ₁ ) as in the conventional case.
The front edge 29a and the rear edge 29b of the upper edge portion 29 of the upper edge portion 29 are aligned with each other and the intermediate portion is bulged outward. The waist opening 33 corresponding to the lower edge portion 32 of the door glass 26 and the weather strip 34 as a "sealing member" attached thereto are formed linearly along the front-rear direction unlike the glass run 13. ing.

According to this embodiment, the upper edge portion 29 of the door glass 26 is linearly formed, whereas the upper edge corresponding portion 21 of the glass run 13 is in a curved state bulging outward. The upper edge portion 29 of the door glass 26 is relatively inward with respect to the upper edge corresponding portion 21 of the glass run 13. Moreover, since the upper edge corresponding portion 21 of the grass run 13 is curved along the curved line L ₂ which coincides with the front end 29a and the rear end 29b of the upper edge portion 29 as described above, the upper edge portion 29 is formed.
The vicinity of the corner K at the intermediate position is particularly inward (see FIG. 2).

Therefore, since the upper edge portion 29 of the door glass 26 is set to the inner side in advance in this way, the negative pressure is applied to the outer surface of the door glass 26 during high-speed traveling,
Even if the upper edge 29 of the door glass 26 is sucked out by a predetermined amount d (the door glass after the movement of 26a in the figure), the upper edge 29 of the door glass 26 and the lip portion 13a of the glass run 13 are The close contact is secured, and it is possible to reliably prevent the generation of air leaks and wind noise during high-speed traveling.

Further, in this embodiment, the waist opening 33
Also, since the weather strip 34 is linearly formed in the front-rear direction so as to correspond to the lower edge portion 32 of the door glass 26, the door glass 26 that is linearly formed in the front-rear direction can be reliably supported. You can Further, the fact that the waist opening 33 is linear facilitates the manufacture of the door.

Further, if the door glass 26 according to this embodiment has a curved shape only in the vertical direction, the manufacturing of the door glass 26 itself becomes very easy, which is advantageous in terms of cost. Further, the door glass 26 is in one direction (vertical direction)
Since it has a curved shape only at 1, the plurality of door glasses 26 can be stacked and stored and transported, which is very convenient.

In the above description, an example in which the door glass 26 and the glass run 13 are curved even in the vertical direction has been shown. However, at least the upper edge portion 29 of the door glass 26 is used in the present invention.
It suffices that the upper edge corresponding portion 21 of the glass run 13 is curved, and the door glass 26 and the glass run 13 may be formed linearly in the vertical direction. That is, the door glass 26
May be completely flat.

Although the front door is taken as an example, the present invention can also be applied to a rear door. Depending on the type of the door, the upper edge 29 of the door glass 26 that moves up and down and the beveled edge 30 may be used.
There is also a square one without.

FIG. 3 is a diagram showing another embodiment of the present invention. In this embodiment, the waist opening 35 remains curved, as is conventional, and the weather strip 34 attached thereto.
You may make only a straight line. For example, the waist opening 35
The outer flange 35a of the waist opening 35
In some cases, the molding 36 having the weather strip 34 is attached via a plurality of resin clips 37.
With such a structure, the intervening resin clip 37 is used.
By changing the thickness W of both ends in the front-rear direction and the central portion in the front-rear direction, the position of the inner surface portion 36a of the molding 36 (that is, the attachment position of the weather strip 34) can be changed. Therefore, even if the waist opening 35 remains curved to some extent, by making the thickness W of the resin clip 37 at the front-rear direction central portion of the waist opening 35 larger than that at the end portion in the front-rear direction, the inner surface portion 36a of the molding 36 is formed. Alternatively, the outer weather strip 34 attached thereto may be formed in a linear shape so as to be in contact with the door glass 26.

[0025]

The door glass support structure for a vehicle door according to the present invention has the contents described above, and the upper edge portion of the door glass is formed linearly.
The seal member of the vehicle body or sash is formed along the curved line in the front-rear direction that bulges outward and matches the front end and rear end of the upper edge, so the middle part of the upper edge of the door glass corresponds. The sealing member is relatively inward. Therefore, the adhesion of the door glass to the seal member is enhanced, and the adhesion of the door glass and the seal member can be ensured even when traveling at high speed.
