Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement in a door glass weather strip for sealing between a door and a door frame when the door glass is closed, such as on a side door of an automobile.

[Conventional technology]

2. Description of the Related Art In order to reduce air resistance and so-called wind noise during high-speed driving of an automobile, a so-called flat surface type automobile has been proposed in which the outer surface of the vehicle body including the door glass and door frame is made flush with the outside surface of the vehicle body. When a car is running at high speed, the door glass is pushed outward due to the pressure difference between the inside and outside of the car, and if this outward displacement cannot be controlled, wind noise and air resistance will increase. Resulting in. As a means for regulating the outward displacement of the door glass while satisfying the above-mentioned request for a flat surface surface, for example, as described in Japanese Utility Model Application Publication No. 56-13015, Some have a clip that is approximately L-shaped in cross section and is attached to the door frame, into which the upper edge of the door glass enters when the door is closed. In this way, the outward displacement of the door glass can be reliably controlled only by the protrusion of the clip in the direction of the thickness of the door glass, but the tip of the clip does not necessarily enter the inside of the clip when closing the door glass. In this case, there is a problem that the seal is incomplete. Clips also have the problem of increasing wind noise. On the other hand, the present applicant first applied for the
As proposed in No. 197854 (see Figures 7 and 8), the door glass weather strip 1 is integrally provided with an outer strip 3 that contacts the upper surface of the upper edge 2A of the door glass 2 when it is fully closed. It is also possible. In this case, when the upper edge of the door glass 2 is displaced outwardly due to the pressure difference between the inside and outside of the vehicle compartment 4, the outer lip 3 resists this movement and moves the upper edge of the door glass 2 outward.
It deforms outward together with A and absorbs the displacement of the door glass. Reference numeral 5 in FIGS. 6 to 8 indicates a door frame, 6
7 indicates a roof side rail, 7 indicates a roof, and 8 indicates a door weather strip. Here, as shown in FIG. 8, the opening/closing locus of the door glass 2 moves the rollers 9 attached to the upper and lower parts of the front edge and rear edge of the door glass 2, respectively, to the door frame 5. This is determined by guiding the door glass 2 in the opening/closing direction by the vertical guide 10 on the side. Reference numeral 9A in FIG. 8 indicates a nut for fixing the roller 9 to the door glass 2.

[Problem that the invention attempts to solve]

Here, when the door glass 2 is in a fully closed state, the outer lip 3 protrudes from the outer surface of the door glass 2 by a step a, so it is difficult to make the side door D completely flush. On the other hand, the outer lip 3 is omitted,
Door glass weather strip 1 is attached to door glass 2.
It is conceivable that only the upper end seal part 1A is inserted between the upper end edge 2A and the door frame 5, but in this case, the upper end edge 2A of the door glass 2 will not touch the inside or outside of the passenger compartment 4 when the car is running at high speed. The pressure difference causes problems such as incomplete sealing or generation of wind noise as the air is sucked outward. This invention was made in view of the above-mentioned conventional problems, and does not require the provision of an outer lip that presses down the outside of the upper edge of the door glass, and does not damage the seal between the upper edge of the door glass and the door frame.
To provide a door glass weather strip structure for an automobile, which allows a door glass and a door frame to be flush with each other without generating wind noise.

[Means to solve the problem]

This invention consists of a door glass weather strip main body that is held on the door frame, and a door glass weather strip main body that is continuously formed integrally with the main body of the door glass weather strip.
an upper end seal part that is inserted between the upper edge of the door glass and the door frame to seal the upper edge and the door frame flush with the outer surface of the door when the door glass is fully closed; In the door glass weather strip structure for an automobile, one end is inserted into the upper end seal at at least one location in the longitudinal direction of the upper end seal, and the other end faces the movement locus of the upper edge of the door glass. When the one end is pushed by the upper edge of the door glass when the door glass is fully closed when the door is parked on the room side, the other end pushes the upper edge of the door glass so that the door glass is flush with the outside surface of the door. This object is achieved by providing a retainer which is adapted to be pushed outwardly to a position where

[Effect]

In this invention, when the door glass is fully closed, when the upper edge contacts and presses the upper end seal, the retainer attached to the upper end seal at one end is rotated by the pressing force, and the retainer is rotated by the pressing force. The other end of the retainer pushes out the upper edge of the door glass from the passenger compartment side to a position where the outer surface of the door glass is flush with the outer surface of the door frame, thereby making the door glass and door frame flush with each other. At the same time, when a force is applied to push the top edge of the door glass outward due to the pressure difference between the inside and outside of the vehicle when the car is running at high speed, the top edge of the door glass is protected from the outward force by the retainer in advance. As a result, the upper edge of the door glass is not pushed outward due to the pressure difference between the outside and the inside of the vehicle.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 5, this embodiment includes a door glass weather strip main body 14A held on a door frame 12 of a side door 10 of an automobile (not shown) and the door glass weather strip main body 14A. The strip is formed continuously and integrally from the main body 14A, and is inserted between the upper edge 16A of the door glass 16 and the door frame 12 when the door glass 16 is fully closed, and is inserted between the upper edge 16A and the door frame 12.
In the structure of the automobile door glass weather strip 14, the door glass weather strip 14 has an upper end sealing portion 14B that seals flush with the outer surface of the side door 10 between the upper end sealing portion 14B and the door frame 1.
At the corner portion 12C from the inclined side 12A of No. 2 to the horizontal side 12B, one end 18
A is inserted, and the other end 18B is inserted into the door glass 16.
When the one end 18A is pushed by the upper end edge 16A of the door glass 16 when the door glass 16 is fully closed, the other end 18B is pushed by the reaction force. A retainer 18 is provided to push the upper edge 16A of the door glass 16 outward to a position where the door glass 16 is flush with the outer surface of the door. The reference numeral 14C in the figure is formed continuously and integrally from the door glass weather strip 14.
Shows the inner lip that contacts and seals the back surface of the cap when it is fully closed. The retainer 18 has one end 18A and the other end 1.
The door glass weather strip 14 is a member that is longer than the door glass weather strip 14 and has a substantially U-shaped cross section.
By inserting the one end 18A into the mounting hole 14D formed inside the connection part to the door glass weather strip main body 14A of the upper end seal part 14B, the door glass weather strip 1 is installed.
It is designed to be installed on 4. Further, in this embodiment, the guide in the opening/closing direction of the door glass 16 and the position regulation in the thickness direction of the door glass 16 are formed by rollers 22 and guides 24 as shown in FIG. It's summery. The cross-sectional shape of the general portion of the door glass weather strip 14 other than the mounting position of the retainer 18 is as shown in FIG. The upper end seal portion 14B includes a hollow portion 14E, and one end 18A of the retainer 18 is provided with a mounting hole 14.
It is designed to be inserted into the hollow part 14E from D. Here, the width of the hollow part 14E and the thickness of the one end 18A of the retainer 18 are determined so that there is play in the thickness direction of the one end 18A of the retainer 18 with respect to the hollow part 14E. Therefore, as shown in FIG. 4, when the door glass 16 is not fully closed, the retainer 18 is in a position rotated counterclockwise in the figure due to its own weight, and one end 18A is hollow. Part 14E,
It is in contact with the inner surface of the door glass 16 side. On the other hand, the moving locus of the door glass 16 is controlled by the rollers 22 and the guides 24 such that when the door glass 16 is fully closed, the upper edge 16A of the door glass 16 is moved to a position that is slightly biased toward the vehicle interior 20 side than the outer surface of the door frame 12. I am supposed to take it. Further, when the other end 18B of the retainer 18 is in a sagging position due to its own weight as shown in FIG. It is as follows. Furthermore, one end 18A and the other end 18 of the retainer 18
The length of B and the intermediate connecting part 1 that connects them
The length relationship of 8C is that one end 18A of the retainer 18
When the upper end seal portion 14B assumes a position connected to the inner surface on the door frame 12 side within the hollow portion 14E, the tip of the other end 18B of the door glass 16 is flush with the outer surface of the door frame 12. It is positioned on the inside surface. Therefore, in this embodiment, the door glass 1
When the door glass 16 is closed, the upper edge 16A of the door glass 16 presses the upper seal part 14B of the door glass weather strip 14, and the hollow part 1 inside thereof presses.
When one end 18A of the retainer 18 in the interior 4E is pushed up, the retainer 18 is swung clockwise in the figure around the outer corner 18D of the one end 18A, and at this time, the other end 18B touches the upper edge 16A of the door glass 16. is pushed outward from the vehicle interior 20 side so that the outer surface of the door glass 16 is flush with the outer surface of the door frame 12. In this state, the door glass 16 is preloaded outward from the original opening/closing locus regulated by the rollers 22 and guides 24, so the retainer 18 and the upper seal portion 14B are normally attached toward the vehicle interior 20. A biasing force has been formed. Therefore, even if the automobile is traveling at high speed in this state and a pressure difference is generated between the inside and outside of the vehicle, and a force is applied to push the door glass 16 outward from the vehicle, the urging force can counter the pushing force, and the door glass 16 can be pushed out. The upper edge 16A of the glass 16 is not pushed outward from the outer surface of the door frame 12. Therefore, the seal and flush state at the upper edge 16A of the door glass 16 are maintained. In the above embodiment, the retainer 18 is attached only to the corner portion 12C of the door frame 12, but the present invention is not limited to this, and the retainer 18 is attached to the corner portion 12C of the door frame 12.
They may be provided at a plurality of locations along the inclined side 12A and the horizontal side 12B. However, if only one retainer 18 is provided,
The upper edge 16A of the door glass 16 is the corner portion 1
Since it is most likely to be displaced outward at the position 2C, it is preferable to provide it at the corner portion 12C. Further, in the above embodiment, the retainer 18 has a substantially U-shaped cross section, but this is because when one end is inserted into the upper end seal portion 14B and this is pushed up by the upper end edge 16A when the door glass is fully closed. , the other end connects the upper edge of the door glass to the door glass 1
Any material that acts to press the door frame 12 until the outer surface of the door frame 6 is flush with the outer surface of the door frame 12 may be used. Therefore, other shapes such as an arcuate cross section or a V-shaped cross section may be used. Further, in the above embodiment, the door glass 1 is moved by the roller 22 and the guide 24 as shown in FIG.
Although the position in the thickness direction is restricted when opening and closing the opening 6, other means may be used.

[Effects of the invention] Since the present invention is constructed as described above, the upper edge of the door glass can be easily aligned with the door frame without damaging the seal or increasing wind noise. It has the excellent effect of being able to achieve unification.
