Description

[Detailed description of the invention] (a) Industrial application field This invention relates to automobile doors.

(b) Prior Art Conventionally, this type of automobile door structure has been known as shown in FIGS. 5 and 6 (see Japanese Utility Model Application Publication No. 11225/1983).

Door window opening periphery 2 formed by door panel 1
A glass run 5 having a substantially U-shaped cross section is attached to the groove 3, which comes into contact with the periphery 4a of the door glass 4 as a window panel when the periphery 4a of the door glass 4 is fitted into the groove 3. . The glass run 5 is formed with an inner lip 5a and an outer lip 5b that sandwich and seal the peripheral edge 4a of the door glass 4. Furthermore, a molding 7 that covers the flange portion 6 of the groove portion 3 is fitted. The member designated by number 8 is a door weather strip that seals the door panel 1 and the vehicle body 9.

The configuration of this prior art is not limited to the type in which the door window opening periphery 2 is formed by the door panel 1 described above, but is also applied to a type in which the door window opening periphery is formed by a door sash.

(c) Problems to be solved by the invention However, in the case of such a conventional door, the outer lip 5b of the glass run 5 and the molding 7 adjacent to the outer lip 5b.
Therefore, there is a problem that the step dimension L from the outer surface 7a of the molding 7 to the outer surface 4b of the door glass 4 is large, which causes wind noise during driving and deteriorates aerodynamic characteristics.

Further, paying attention to the molding 7, the molding 7 is fitted into the flange portion 6 and does not fall off easily, but there is a risk that it may fall off if it is touched strongly by hand.

This idea was created by focusing on these conventional problems, and was developed to reduce wind noise and improve aerodynamic characteristics, while also improving the retention of moldings without increasing costs. The purpose is to provide doors.

(d) Means for Solving the Problems In order to achieve the above object, this invention provides a structure in which a glass run having an inner lip that comes into contact with the inner surface of the window panel is attached to the groove at the periphery of the door window opening to form the groove. A molding having a soft member that covers the flange portion, contacts the outer surface of the window panel, and cooperates with the inner lip to hold the window panel is fitted to the flange portion, and an inner edge of the molding is fitted. A bent portion is formed in which the end of the glass run can be engaged, and a retaining piece is protruded to be inserted and locked into a hole formed at the bottom of the groove.

(e) Effect With this configuration, the soft member of the molding and the inner lip of the glass run cooperate to hold and seal the window panel from the inside and outside, so there is no need to provide an outer lip on the glass run, and the outer lip of the molding and the outer surface of the window panel This makes it possible to significantly reduce the height difference between the wheels, reduce wind noise while driving, and improve the aerodynamic characteristics by making the vehicle more flush.

Furthermore, due to the engagement between the bent portion formed on the inner edge of the molding and the end of the glass run, and the engagement between the retaining piece of the molding and the hole formed at the bottom of the groove, the molding can be strongly touched by hand. The molding can be firmly held without falling off even when the window panel is held and sealed securely.

(f) Embodiment In FIGS. 1 and 2, the door D according to this embodiment has an outer panel 10 formed integrally with the outer panel of the door body, and an inner panel 12 formed integrally with the inner panel of the door body. and has
The outer panel 10 and the inner panel 12 are hemmed together at their end portions.

A channel plate 16 that holds the door weather strip 8 is welded to the outer periphery of the shelf 12a of the inner panel 12, and a bottom 18a of a U-shaped frame 18 is welded to the inner periphery of the shelf 12a. An outer flange 18b of the frame 18 is welded to a flange 10a of the outer panel 10.

However, the outer panel 10 and the inner panel 12
and the frame 18 to form a groove 20 at the periphery of the door window opening.
is formed.

A glass run 26 made of rubber is provided in the groove 20, and includes an L-shaped base 22 and an inner lip 24 that extends from the lower end of the base 22 and comes into contact with the inner surface 30a of the door glass 30 as a window panel.
is installed. Specifically, the bottom part of the base part 22 is fitted into the frame 18, and the inner lip 2
The terminal of the inner panel 12 is fitted in near 4.

The outer flange portion 32 of the groove portion 20 (formed by the flange 10a of the outer panel 10 and the flange 18b of the frame 18) has this flange portion 3
2 is fitted with molding 34 that covers it.

This molding 34 includes a substantially U-shaped stainless steel main body 36, an end cap 38 covering the end of an outer piece 36a of this main body 36, and a main body 36.
A soft member 40 made of resin such as soft PVC and having a hardness of approximately 90° or less is coated between the inner piece 36b, which is the inner edge of the
The outer covering portion of the inner piece 36b of 0 comes into contact with the outer surface 30b of the door glass 30 and cooperates with the inner lip 24 to hold and seal the door glass 30.

A retaining piece 42 is protruded from the edge of the inner piece 36b of the molding 34 at an appropriate interval. This retaining piece 42 is also covered with the soft member 40.

On the other hand, the bottom of the groove 20 specifically the frame 18
A hole 44 is formed in the bottom 18a of the molding 3 at a position corresponding to the retaining piece 42.
4 into the flange portion 32 and simultaneously inserted into the hole 44 and engaged with the peripheral edge of the hole 44.

Further, a bent portion 36c is formed in the middle of the inner piece 36b of the main body 36, and this bent portion 36c is engaged with the end 22a of the glass run base portion 22. The soft member 40 and the end cap 38 can be formed by co-extrusion molding with the stainless steel main body 36, or the end cap 38 can be formed as a separate piece and fitted later.

Note that the outer surface of the main body 36 of the molding 34 (the outer surface of the outer piece 36a) and the general surface of the outer panel 10 are designed to be substantially smoothly continuous.

With this configuration, the door glass 30 is held and sealed by the cooperation between the inner lip 24 of the glass run 26 and the soft member 40, so that the glass run has a conventional outer lip 5b (see FIG. 6).
It is no longer necessary to provide a molding, and the step L between the outer surface of the molding and the outer surface 30b of the door glass 30 can be significantly reduced, reducing wind noise while driving and making the vehicle more flush, resulting in improved aerodynamic characteristics. can be done.

In addition, since the retaining piece 42 of the molding 34 is locked around the hole 44 of the frame 18, even if the molding 34 is strongly touched by hand, it strongly resists the molding 34 from falling off and holds the molding 34 firmly. By holding the door glass 30, the holding and sealing performance of the door glass 30 can be stably ensured.

Furthermore, the engagement between the bent portion 36c of the inner body piece 36b and the end of the glass run base portion 22 improves the ability to prevent the glass run 26 from falling off. FIG. 3 shows an example in which the prevention of the molding 34 from falling off is further improved. That is, by providing a rib 50 protruding from the end cap 38 in a direction opposite to the direction in which the molding is fitted, and by bringing the rib 50 into contact with the flange portion 32, the effect of preventing the molding 34 from coming off can be further improved. As shown in FIG. 4, a retaining rib 50 may be provided to protrude from the middle of the outer piece 36a of the stainless steel main body 36.

(g) Effects of the invention According to this invention, it is possible to stably maintain and seal the window panel, prevent the molding from falling off, and reduce wind noise while driving. This has the effect of improving aerodynamic characteristics.
