Description of the Related Art FIG. 4 is a plan view of a conventional automobile window molding and a window glass to which the automobile window molding of the present invention is attached, and FIG. 5 shows a conventional automobile window molding in a straight portion of the window glass. FIG. 6 is a cross-sectional view of a conventional automobile window molding in a corner portion of a window glass.

Generally, an automobile wind molding is mounted in a gap between a window glass such as a windshield or a rear glass of an automobile and a window frame of a vehicle body, and a design portion thereof forms a gap between the window glass and the window frame. While covering and improving the appearance quality, rainwater and the like are prevented from flowing into the concave groove in the gap between the window glass and the window frame. However, in the automobile wind molding on the windshield side of the automobile, rainwater and the like flow along the surface of the design portion into the surface of the window glass,
In order to prevent the visibility of the window glass from being reduced, in recent years, as shown in FIG. 5, the design portion 1a that covers the gap between the window glass 11 and the window frame 12 is omitted, and the window glass 11 is A windmill for automobiles has been proposed in which a drain gutter 10 is formed along the circumference between a windshield for automobiles and a window frame 12 to provide a rain gutter function for preventing rainwater and the like from flowing into the window glass 11. There is.

That is, in FIG. 5, an automobile window molding is formed in a long shape from a synthetic resin material such as polyvinyl chloride and has a shape that covers the peripheral edge of the window glass 11.
And a base portion 2 that is integrally erected on the back surface side of the head portion 1. One end of the head 1 (end of the window glass 11 side)
The pressure contact piece 3 that elastically contacts the surface of the window glass 11 is integrally formed therewith, and the other end of the head portion 1 (the end portion on the side of the window frame 12) covers the gap between the window glass 11 and the window frame 12. Instead, a gap is formed between the side wall surface 12a of the window frame 12. Further, a receiving piece 4 is integrally formed on a side of the base 2 on the side of the window glass 11 that extends obliquely at an elevation angle toward the back surface of the window glass 12 and has its tip elastically contacting the back surface of the window glass 12. Has been done. The pressure contact piece 3 of the head 1 and the base 2

Inside the base 2, an insert 5 for reinforcement and expansion / contraction that is formed of a wire material such as a metal wire is embedded along the longitudinal direction.

On the other hand, a rain gutter lip 6 having a substantially uniform thickness as a whole is integrally projectingly formed on a side portion of the base portion 2 on the side of the window frame 12. The rain gutter lip 6 has elasticity and bends in accordance with the variation in the gap between the end surface of the window glass 11 and the side wall surface 12a of the window frame 12 to make the window frame 12
It is formed so as to absorb the variation by changing the contact area with the side wall surface 12a. That is, even when the gap between the end surface of the window glass 11 and the side wall surface 12a of the window frame 12 is maximum, at least a part of the tip of the rain gutter lip 6 elastically contacts the side wall surface 12a of the window frame 12 and End face of glass 11 and side wall face 1 of window frame 12
When the gap with 2a is minimized, the rain gutter lip 6 is largely curved to increase the contact area with the side wall surface 12a of the window frame 12 and hold the window glass 11 in a stable position in the window frame 12. To do. Then, in a state in which the window glass 11 having the automobile window molding attached thereto is assembled to the window frame 12 of the vehicle body, as shown in FIG. The upper surface of the gutter lip 6 and the side wall surface 12a of the window frame 12 form a drain groove 10 having a rain gutter function of preventing rainwater from flowing into the window glass 11 from the window frame 12 and draining rainwater. ..

Next, the assembling work of the conventional automobile window molding constructed as described above will be described.

First, the adhesive 2 is provided between the adhesive sealing dam 21 attached to the bottom wall of the window frame 12 and the side wall of the window frame 12.
The window glass 11 that is filled with 2 and fits into the window frame 12 is placed on the dam 21, and the automobile window molding is inserted through the pressure contact piece 3 and the receiving piece 4 into the window glass 11.
The base 2 is inserted into the uncured adhesive 22 while being attached to the peripheral edge of the. At this time, at least the tip portion of the rain gutter lip 6 is at the side wall surface 12a of the window frame 12.

The window glass 11 is positioned in the window frame 12 at a stable position by absorbing the variation in the gap with the window 2a.

As a result, the windmill for automobiles is
The window glass 11 is attached to the peripheral edge of the window glass 11 in a sandwiched state, and is pressed toward the window glass 11 by the elastic force of the rain gutter lip 6 to prevent the window glass 11 from being separated, and at the same time, the window glass. Hold 11 in a stable position within window frame 12. Then, when the adhesive 22 filled between the dam 21 and the side wall of the window frame 12 is cured, the automobile window molding is fixed to the gap between the window glass 11 and the window frame 12 via the base portion 2, The window glass 11 is assembled and fixed to a predetermined position in the window frame 12 via the automobile window molding. Then, the drain groove 10 is formed along the periphery of the window glass 11 by the side surfaces of the head 1 and the base 2 of the automobile window molding on the side of the window frame 12, the upper surface of the rain gutter lip 6 and the side wall surface 12a of the window frame 12. Is formed.

[0009]

Since the conventional automobile window molding is constructed as described above, the straight portion 11a (see FIG. 4) of the window glass 11 has the structure shown in FIG.
As shown in FIG. 3, the rain gutter lip 6 elastically contacts the side wall surface 12 a of the window frame 12, and the end face of the window glass 11 and the window frame 1 are connected.

EXAMPLES Examples of the present invention will be described below.

FIG. 1 is a sectional view of an automobile window molding of a first embodiment of the present invention, and FIG. 2 is an enlarged sectional view of a rain gutter lip of an automobile window molding of the first embodiment of the present invention. In the figure, the same reference numerals and symbols as those of the conventional example indicate the same or corresponding parts as those of the conventional example.

The automobile window molding of the first embodiment has a main feature in the structure of the rain gutter lip 7 formed on the side portion of the base portion 2 on the window frame 12 side. That is, as shown in the drawing, the rain gutter lip 7 has a base end portion 7a integrally formed on the side of the base portion 2 on the window frame 12 side and a tip end integrally formed on the base end portion 7a. Part 7
b. The tip portion 7b as a whole has the same thickness Y as the rain gutter lip 6 in the conventional example, extends slightly curved toward the side wall surface 12a of the window frame 12, and does not elastically deform in a normal state. In, the end surface of the window glass 11 and the side wall surface 12 of the window frame 12
has a width approximately the same as or slightly larger than the range of the variation C of the gap with a (the difference between the maximum value A and the minimum value B of the gap),
It has elasticity so that at least a part thereof is always in elastic contact with the side wall surface 12a of the window frame 12.

On the other hand, the base end portion 7a as a whole has a wall thickness X which is about 2 to 3 times the wall thickness Y of the front end portion 7b, and has a greater rigidity in the thickness direction than the front end portion 7b, and The window frame 12 extends slightly curved toward the side wall surface 12a. In addition, the base end portion 7a of the rain gutter lip 7 bends by bending the tip end portion 7b elastically against the side wall surface 12a of the window frame 12 and forming a gap between the end surface of the window glass 11 and the side wall surface 12a of the window frame 12. Within the range in which the variation C is absorbed, the shape is maintained and is not bent. Further, in the base end portion 7a of the rain gutter lip 7, the gap between the end surface of the window glass 11 and the side wall surface 12a of the window frame 12 becomes smaller than a predetermined minimum value B, and the tip portion 7b has the variation. When it cannot be absorbed, it has elasticity to such an extent that it is bent by the pressing force applied through the tip portion 7b and absorbs the variation. In the first embodiment, the thickness of the boundary portion between the base end portion 7a and the tip end portion 7b of the rain gutter lip 7 is gradually reduced.

Here, the thickness X of the base end portion 7a and the thickness Y of the tip end portion 7b of the rain gutter lip 7 in the embodiment of the present invention are defined by the rain from the virtual plane of the base 2 on the rain gutter lip 7 side. The length up to the tip of the gutter lip 7 is defined as the length of the rain gutter lip 7, and is defined as the dimension measured at 20% inside from both ends.

The thickness X of the base end portion 7a is about 2 to 3 times the thickness Y of the tip end portion 7b as a whole, and the rain gutter lip is provided in the curved portion such as the corner portion 11b of the window glass 11. It suffices that the tip 7b can be prevented from being rolled up as a whole and the tip 7b can be prevented from being separated from the side wall surface 12a of the window frame 12, and the range of the wall thickness X of the base end portion 7a with respect to the wall thickness Y of the tip portion 7b can be determined. It also includes a case where the range of the rain gutter lip 7 slightly exceeds the range of 2 to 3 depending on changes in various conditions such as the material, size, and outer shape of the rain gutter lip 7.

Next, in the automobile window molding of the present embodiment having the above-described structure, the window frame 12 is formed in a conventional manner.
Assembled to. That is, while the automobile window molding is mounted on the peripheral edge of the window glass 11 placed on the dam 21 via the pressure contact piece 3 and the receiving piece 4, the base 2 is connected to the dam 21 and the side wall of the window frame 12. It is inserted into the uncured adhesive 22 filled in between. At this time, the window glass 1
According to the gap between the end surface of No. 1 and the side wall surface 12a of the window frame 12,
The tip portion 7b of the rain gutter lip 7 makes at least a part thereof elastically contact the side wall surface 12a of the window frame 12. On the other hand, the base end portion 7a having a wall thickness about 2 to 3 times as large as that of the tip end portion 7b is not bent and deformed, and the rain gutter lip 7 has only the tip end portion 7b on the end face of the window glass 11 and the side of the window frame 12. By absorbing the variation C in the gap with the wall surface 12a, the window glass 1
1 is positioned and held in a stable position in the window frame 12.

In the curved portion such as the corner portion 11b of the window glass 11, as a result of the bending of the automobile wind molding, a stress in the thickness direction acts on the rain gutter lip 7 through the base portion 2 to cause the rain gutter. The entire lip 7 tries to roll up. However, since the base end portion 7a exerts rigidity and retains its shape in the thickness direction against the stress applied via the base portion 2, a part of the tip end portion 7a is rolled up, but The entire gutter lip 7 does not roll up. Therefore, regardless of the straight portion 11a and the corner portion 11b of the window glass 11, the tip end portion 7b of the rain gutter lip 7 is always the side wall surface 12a of the window frame 12.
Rain gutter lip 7
Seals the adhesive 22 to prevent exposure and leakage to the outside, and forms the drain groove 10 together with the head 1, the base 2 and the side wall of the window frame 12. As a result, the rain gutter lip 7 surely elastically contacts the tip end portion 7b with the side wall surface 12a of the window frame 12 around the window glass 11 to maintain a good appearance quality. Further, the drain gutter 10 formed by the rain gutter lip 7 together with the head portion 1, the base portion 2 and the side wall of the window frame 12 guides the rainwater flowing on the surface of the window frame 12, and the rainwater etc. It is prevented from flowing along the surface and flowing into the surface of the window glass 11 to reduce the field of view thereof.

It should be noted that the tip portion 7b of the rain gutter lip 7 does not contact the side wall surface 12a of the window frame 12 in a normal state, so that a gap between the end surface of the window glass 11 and the side wall surface 12a of the window frame 12 is formed. Since it has a width that is about the same as or slightly larger than the range of the variation C and is always formed so as to elastically contact the side wall surface 12a of the window frame 12, a part of the front end portion 7b is rolled up in the curved portion of the window glass 11. Even if the other end of the window frame 12 is always in contact with the side wall surface 12a of the window frame 12,
Does not come off from the side wall surface 12a of the window frame 12.

Further, in the rain gutter lip 7, the gap between the end face of the window glass 11 and the side wall face 12a of the window frame 12 becomes smaller than a predetermined minimum value B, and the tip portion 7b can absorb the variation. Even if it disappears, the base end portion 7a has elasticity to such an extent that it is bent by the pressing force applied through the tip end portion 7b to absorb the variation,
There is no possibility that the automobile wind molding cannot be mounted in the gap between the window glass 11 and the window frame 12.

The automobile window molding mounted on the peripheral portion of the window glass 11 is mainly composed of a rain gutter lip 7.
It is pressed toward the window glass 11 by the elastic force of the front end portion 7b thereof, is prevented from being separated from the window glass 11, and holds the window glass 11 at a stable position in the window frame 12. When the adhesive 22 filled between the dam 21 and the side wall of the window frame 12 cures, the window glass 11
Is assembled and fixed to a predetermined position in the window frame 12 via the automobile window molding, and the side surfaces of the head portion 1 and the base portion 2 of the vehicle window molding on the window frame 12 side, the upper surface of the rain gutter lip 7 and the window frame 12 are attached. The drain groove 10 is formed along the periphery of the window glass 11 by the side wall surface 12a.

As described above, in the automobile window molding of the first embodiment, the rain gutter lip 7 formed on the side portion of the base portion 1 on the side of the window frame 12 is formed by the base end portion 7a and the tip end portion 7b. Then, the tip end portion 7b is formed as a whole with a thickness Y that is about the same as that of the rain gutter lip 6 in the conventional example so that at least a part thereof comes into elastic contact with the side wall surface 12a of the window frame 12, and the base end portion 7a. Is made to have a wall thickness X which is about 2 to 3 times or more the tip portion 7b as a whole.

Therefore, in the first embodiment, in the straight portion 11a of the window glass 11, the tip portion 7b of the rain gutter lip 7 is elastically contacted with the side wall surface 12a of the window frame 12 to form the end surface of the window glass 11. The variation C in the gap between the window frame 12 and the side wall surface 12a is absorbed, the window glass 11 is held at a stable position in the window frame 12, and at the curved portion of the window glass 11, the base end portion 7a is formed. Shows rigidity, and base 2
The shape is retained in the thickness direction against the stress applied to the rain gutter lip 7, and the rain gutter lip 7 is prevented from being rolled up as a whole to prevent the tip portion 7b from being separated from the side wall surface 12a of the window frame 12. As a result, regardless of the straight portion 11a and the curved portion of the window glass 11, the tip portion 7b of the rain gutter lip 7 does not always come into elastic contact with the side wall surface 12a of the window frame 12 and come off. While maintaining good appearance quality in the surroundings, the drain gutter 10 formed by the rain gutter lip 7 together with the head portion 1, the base portion 2 and the side wall of the window frame 12 guides rainwater flowing on the surface of the window frame 12. Rainwater, etc., travels along the surface of the head 1 and the window glass 1
It prevents it from flowing into the surface of No. 1 and lowering its visibility.

By the way, in the above-mentioned first embodiment, the wall thickness of the boundary portion from the base end portion 7a to the tip end portion 7b of the rain gutter lip 7 is gradually reduced. Is not limited to this,
If the thickness X of the base end portion 7a as a whole is about 2 to 3 times or more the thickness Y of the tip end portion 7b, the shape of the boundary portion can be arbitrarily selected. Further, the shapes of the base end portion 7a and the tip end portion 7b are not limited to those shown in FIGS. 1 and 2, and can be arbitrarily changed.

FIG. 3 is an enlarged cross-sectional view of the rain gutter lip of the automobile window molding according to the second embodiment of the present invention.

The second embodiment is different from the first embodiment in the sectional shape of the rain gutter lip 8 as a whole, and the other construction is the same as that of the first embodiment. That is,
As shown in the figure, the tip portion 8b of the rain gutter lip 8 as a whole has a wall thickness similar to that of the rain gutter lip 6 in the conventional example and extends substantially linearly, and the wall thickness gradually increases toward the tip. Is decreasing. On the other hand, the base end 8a
Has a thickness that is approximately 2 to 3 times or more the thickness of the tip portion 8b as a whole, and extends substantially linearly toward the side wall surface 12a of the window frame 12.

The tip portion 8b is not elastically deformed in a normal state, and the end surface of the window glass 11 and the window frame 12 are in a normal state.
The width is approximately the same as or slightly larger than the range of the variation C of the gap between the side wall surface 12a and the side wall surface 12a, and is elastic so that at least a part thereof is always elastically contacted with the side wall surface 12a of the window frame 12. Further, the base end portion 8a is the tip end portion 8b.
Retains its shape within a range that absorbs the variation C in the gap between the end surface of the window glass 11 and the side wall surface 12a of the window frame 12, and the end surface of the window glass 11 and the side wall surface 12a of the window frame 12 are retained. Gap becomes smaller than the predetermined minimum value B,
When the tip portion 8b cannot absorb the variation, the tip portion 8b bends due to the pressing force applied via the tip portion 8b and has elasticity enough to absorb the variation. Also in the second embodiment, the thickness of the boundary portion from the base end portion 8a to the tip end portion 8b of the rain gutter lip 8 is gradually reduced.

The automobile window molding of the second embodiment is similar to the first embodiment in that the straight portion 11 of the window glass 11 is used.
In a, the tip portion 8b of the rain gutter lip 8 elastically contacts the side wall surface 12a of the window frame 12 to absorb the variation C in the gap between the end surface of the window glass 11 and the side wall surface 12a of the window frame 12, The glass 11 is held at a stable position in the window frame 12, and in the curved portion of the window glass 11, the base end portion 8a exerts rigidity and resists the stress applied to the base portion 2 in the thickness direction. The shape is maintained, and the rain gutter lip 8 is prevented from being rolled up as a whole to prevent the tip portion 8b from being detached from the side wall surface 12a of the window frame 12.
As a result, regardless of the straight portion 11a and the curved portion of the window glass 11, the tip portion 8b of the rain gutter lip 8 does not always come into elastic contact with the side wall surface 12a of the window frame 12 and come off, and the window glass 11 A drain gutter 10 formed by the rain gutter lip 8 together with the head portion 1, the base portion 2 and the side wall of the window frame 12 while maintaining good appearance quality in the surroundings.
However, it guides rainwater and the like flowing on the surface of the window frame 12 to prevent rainwater and the like from flowing along the surface of the head 1 and flowing into the surface of the window glass 11 to lower the visibility.

By the way, a tip portion of a predetermined wall thickness is formed so as to project on the side of the window frame 12 side of the base 2 of the automobile window molding of this embodiment, and at least a part of which is elastically contacted with the side wall surface 12a of the window frame 12. The rain gutter lips 7, 8 having 7b, 8b and base end portions 7a, 8a having a wall thickness approximately 2 to 3 times as large as the tip end portions 7b, 8b may be made of soft synthetic resin or hard synthetic resin. In particular, it is preferable that the tip portions 7b and 8b are made of a soft synthetic resin and the base end portions 7a and 8a are made of a hard synthetic resin. That is, the base end portion 7 when implementing the present invention
a and 8a are integrated with the base 2, and the bending center originally at the center of the base 2 with respect to the bending of the corner is changed to the base end 7a,
8a side, and as a result,
Because it reduces the expansion and contraction changes,
The thickness of the tip portions 7b and 8b is preferably not only a change in strength due to the thickness but also a material which is rich in elasticity.

[0032]

As described above, in the automobile window molding of the present invention, at least a part of the rain gutter lip projectingly formed on the side portion of the base on the window frame side is elastically contacted with the side wall surface of the window frame. Since it is composed of a tip portion having a predetermined thickness and a base end portion having a thickness about 2 to 3 times or more that of the tip portion,
In the straight part of the window glass, the tip of the rain gutter lip elastically contacts the side wall surface of the window frame to absorb the variation in the gap between the end surface of the window glass and the side wall surface of the window frame. While holding in a stable position in the frame, in the curved portion of the window glass, the base end portion exhibits its rigidity and maintains its shape in the thickness direction against the stress applied through the base portion, In order to prevent the rain gutter lip from curling up as a whole and to prevent the tip part from separating from the side wall surface of the window frame, the tip part of the rain gutter lip is fixed regardless of the straight part and the curved part of the window glass. It does not always come in contact with the side wall of the window frame by elastic contact.
