Abstract

PROBLEM TO BE SOLVED: To provide an automobile window glass peripheral mole wherein no falling or warping is produced in an attached state. SOLUTION: A first extended part 22C is extended from the upper end of the base part 22 of a peripheral moulding 10, a second extended part 22D is extended from its middle part and a rear window glass 14 is held between these extended parts. A rain gutter 28 extended in a side opposite the second extended part 22D seals a gap between the rear window glass 14 and a window frame 16. The lower end of the base part 22 is offset to the extended part 16A side of the window frame 16 and a contact part 32 is formed in yet further lower end. The base part 22 is formed such that its thickness is gradually reduced from the upper end toward the lower end. Since the contact part 32 is brought into contact with the receiving part 16B of the window frame 16 even when a force of an arrow direction B is applied to the rear window glass 14, no warping is produced in the peripheral moulding 10. No falling is produced, either, since the thick part of the base part 22 is highly rigid.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile window glass peripheral molding for closing a gap between an outer peripheral portion of a window glass and a window frame.

[0002]

2. Description of the Related Art As shown in FIG. 4, a window glass 52 is attached to a window frame 54 via a sealing material 64. The peripheral edge molding 50 of the window glass of the automobile is interposed between the window glass 52 and the window frame 54 to close the gap between the window glass 52 and the window frame 54.

The window glass peripheral molding 50 is provided with a base portion 56 made of a hard synthetic resin. The first extending portion 58A extends from the upper end in the height direction of the base portion 56, and the second extending portion 58B extends from the middle portion. The first extending portion 58A and the second extending portion A sandwiching portion 62 made of a soft resin is formed on the surface facing 58B. The window glass 52 is sandwiched between the sandwiching portions 62, so that the sandwiching portion 62 closely contacts and sandwiches the window glass 52 from the thickness direction of the window glass 52.

A rain garter 60 formed of a soft synthetic resin extends from an intermediate portion of the base portion 56 toward the bent portion 54B of the window frame 54. The extended end of the rain gutter 60 elastically abuts on the upper portion of the bent portion 54B of the window frame 54, and prevents rainwater or the like from entering between the window glass 52 and the window frame 54.

By the way, the lower portion of the base 56 is a sealing material 64.
However, when the amount of the sealing material 64 is small, the lower portion of the base 56 is not embedded in the sealing material 64 as shown in FIG. When a force is applied in two directions, the base 56
Sometimes rotated in the direction of arrow E, causing a so-called "fall".

On the other hand, even when the amount of the sealing material 64 is large,
Before curing, as shown in FIG. 6, the rotation of the base portion 56 is blocked by the sealing material 64, but since the rigidity of the base portion 56 is low, the upper portion of the base portion 56 has the bent portion 54B of the window frame 54. There were times when it was bent in the direction.

SUMMARY OF THE INVENTION In consideration of the above facts, an object of the present invention is to obtain a peripheral molding of a window glass of an automobile which does not fall or warp in a mounted state.

[0008]

According to another aspect of the present invention, there is provided a peripheral window molding for an automobile window, a base portion disposed in a gap between a window frame of a vehicle body and an outer peripheral portion of the window glass, and an upper end and an intermediate portion of the base portion. An insertion recess formed by a protruding extension into which the outer peripheral portion of the window glass is inserted, and an extension extending from a portion of the base opposite to the insertion recess, and closely contacted over the entire window frame. A rain gutter that forms a passage of rainwater, and an abutting portion that bulges from the lower end of the base to the outside of the window frame from the center of rotation of the base when the upper end of the base rotates in a direction approaching the outside of the window frame, It is characterized by having.

The insertion recess of the peripheral molding is inserted into the outer peripheral portion of the window glass. Next, when the window glass with the peripheral molding is attached to the window frame of the vehicle body, the rain gutter closely adheres along the entire outer peripheral portion of the window frame to form a groove, so that rainwater or the like may be present between the window frame and the window glass. Never intrudes.

When a force toward the outside of the window frame acts on the peripheral molding due to the fine adjustment of the mounting position of the window glass, the base portion tries to rotate in a direction in which the upper end approaches the outside of the window frame. Here, the lower end of the base portion is formed with a contact portion that bulges outside the window frame with respect to the center of rotation of the rotation of the base portion. Therefore, when the base portion tries to rotate, the contact portion comes into contact with the window frame, and the rotation resistance acts as a tension. Therefore, the base does not rotate.

According to a second aspect of the present invention, in the peripheral molding of window glass of an automobile, the abutting portion is formed of a softer material than the base portion.

Therefore, the contact portion elastically spreads and is widely grounded with the window frame, so that the grounding property is improved. According to a third aspect of the present invention, in the peripheral molding of window glass of an automobile, the base is thick.

According to a fourth aspect of the present invention, there is provided a peripheral window molding for an automobile window glass, wherein a surface of the base portion opposite to the insertion recess is inclined from an upper end to a lower end of the base portion, and the base portion is gradually thickened toward the lower end. It is characterized by being.

In the state before the sealing material filled between the window glass and the window frame is completely hardened, even if a force toward the outside of the window frame acts on the peripheral molding, the base is rotated by the sealing material. Be blocked. Therefore, this force acts as a force to bend the upper portion of the base portion, that is, the upper side of the insertion concave portion, toward the outside of the window frame. However, since the base portion is thick and has high rigidity, the upper portion of the base portion does not warp toward the outer peripheral portion of the window frame.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 3, a peripheral window molding 10 of a window glass according to an embodiment of the present invention includes, for example, a rear window glass 14 of an automobile and a window frame 16 to which the rear window glass 14 is attached. To be installed between.

As shown in FIG. 2, the window frame 16 includes a bent portion 16A bent from the body 12 of the automobile at a substantially right angle, and a receiving portion extending from the end of the bent portion 16A in parallel with the body 12. 16B and.

A sealing material 20 is injected between the receiving portion 16B of the window frame 16 and the rear window glass 14, and the rear window glass 14 is bonded and fixed to the window frame 16 by this sealing material 20. There is.

The peripheral edge molding 10 of the window glass is elongated and is composed of a base portion 22, a sandwiching portion 24, a design portion 26, a rain gutter 28 and an abutting portion 32.

The base portion 22 is mounted in the gap between the rear window glass 14 and the bent portion 16A (see FIG. 3). Base 2
2 has a thickness gradually increasing from the upper end to the lower end, and the lower end of the base portion 22 has a rear window glass 14
An axis line J passing through the center of rotation of the base portion 22 that occurs when a force in the direction of the arrow a (see FIG. 2) is applied to the window frame 16 and is orthogonal to the receiving portion 16B of the window frame 16 when the peripheral edge molding 10 of the window glass is attached. Is offset so as to be located on the bent portion 16A side of the window frame 16.

A first extending portion 22C extends from the upper end of the base portion 22 toward the rear window glass 14 side. Similarly, a second extending portion 22D extends from the middle portion of the base portion 22 toward the rear window glass 14 side.

The first extending portion 22C, the second extending portion 22D and the base portion 22 form an insertion concave portion 22F into which the outer peripheral portion of the rear window glass 14 is inserted.

A pair of metal wires 30 are attached to the base 22.
It is embedded over the entire longitudinal direction at a predetermined interval in the vertical direction. As a result, the peripheral edge molding 10 of the window glass is prevented from being deformed at the time of extrusion molding, and the base portion 22 of the peripheral edge molding 10 of the window glass is reinforced and rigidity is enhanced.

A sandwiching portion 24 is formed of a material softer than the base portion 22 on the opposing surfaces of the first extending portion 22C and the second extending portion 22D. The surface of the holding portion 24 on the side of the second extending portion 22D is formed in a sawtooth shape, and the rear window glass 14
Can be clamped with a high clamping force.

A metallic glitter film is embedded in the upper surface of the base portion 22 and the upper surface of the first extending portion 22C, whereby the design portion 26 is formed. Due to the design portion 26, the base portion 22 is not exposed to the outside of the vehicle cabin, and the aesthetic appearance is improved.

A rain garter 28 having a substantially arcuate cross section extends from a portion of the base portion 22 opposite to the second extending portion 22D. The rain gutter 28 is made of a material softer than the base 22.

At the lower end of the base portion 22, an abutting portion 32 is provided.
It is formed of a material softer than 2. The contact portion 32 is offset from the axis J in the direction of the bent portion 16A of the window frame 16.

Next, the operation of the peripheral edge molding 10 of the window glass according to this embodiment will be described. First, the rear window glass 14 is inserted into the insertion recess 22F of the window glass peripheral molding 10, and the window glass peripheral molding 10 is attached to the rear window glass 14. At this time, the first extending portion 22C
The elastic reaction force of the second extending portion 22D causes the sandwiching portion 24 to sandwich the rear window glass 14 from the thickness direction so that the rear window glass 14 is closely attached.
Since the holding portion 24 is formed of a material that is softer than the base portion 22, the holding portion 24 firmly adheres to the rear window glass 14.

Next, the rear window glass 14 to which the peripheral edge molding 10 of the window glass is attached is installed in the window frame 16. A sealing material 20 is filled between the rear window glass 14 and the receiving portion 16B of the window frame 16.

As shown in FIG. 2, the rear window glass 1
4 is fixed to the window frame 16 by the sealing material 20. At this time, the contact portion 32 of the peripheral molding 10 of the window glass is embedded in the sealing material 20. Further, the contact portion 32 and the receiving portion 1
A predetermined small gap is formed between the 6B and 6B.

Further, the rain garter 28 is elastically bent in the direction of arrow A, and comes into close contact with the bent portion 16A of the window frame 16.
That is, the gap between the rear window glass 14 and the window frame 16 is completely closed by the rain gutter 28.

Since the rain gutter 28 is formed of a material softer than the base 22, it is easily elastically deformed to absorb the dimensional variation of the window frame 16. In addition, window frame 1
Since it strongly adheres to the bent portion 16A of No. 6, rainwater and dust are prevented from entering the gap between the rear window glass 14 and the window frame 16.

On the other hand, the contact portion 32 is located offset from the axis J toward the bent portion 16A. Seal material 2
When the amount of 0 is small and a force in the direction of arrow B is applied to the rear window glass 14, the peripheral edge molding 10 of the window glass
A rotational moment in the direction of arrow C around the lower end of the base portion 22 is generated in the. However, since the contact portion 32 is offset toward the bent portion 16A side with respect to the center of this rotation, when the contact portion 32 slightly rotates, the receiving portion 16B.
It comes into contact with and becomes a resistance against rotation in the form of being stretched.
Therefore, the receiving portion 16B prevents the contact portion 32 from rotating, and the peripheral edge molding 10 of the window glass does not rotate.

When the contact portion 32 hits the receiving portion 16B, it elastically bends and comes into close contact with the receiving portion 16B. Therefore, the contact area between the contact portion 32 and the receiving portion 16B is increased, and the grounding property of the contact portion 32 is improved.

On the other hand, when a force in the direction of arrow B is applied to the rear window glass 14 before a sufficient amount of the sealing material 20 is filled and completely hardened, the lower portion of the base portion 22 and the contact portion 32 are sealed. Since it is embedded in the material 20, the peripheral edge molding 10 of the window glass does not rotate. Therefore, the force in the arrow B direction is applied to the intermediate portion of the base portion 22, that is, the second extending portion 2
It acts as a force to bend the upper portion of the base portion 22 toward the bent portion 16A side of the window frame 16 centering around the portion where 2D is extended. However, even if such a force acts on the base portion 22, the base portion 22 gradually becomes thicker from the upper end to the lower end, and the thick portion has high rigidity against warpage, and thus the base portion 22 has a high rigidity. The upper portion is the bent portion 16A of the window frame 16
It does not warp to the side.

In the present embodiment, there is a case where a predetermined slight gap is formed between the contact portion 32 and the receiving portion 16B of the window frame 16 when the peripheral edge molding of the window glass is used. As shown, the abutting portion 32 has the receiving portion 16 from the beginning of use.
It may be in contact with B.

Further, in this embodiment, the case where the peripheral edge molding 10 of the window glass is used between the rear window glass 14 and the window frame 16 to which the rear window glass 14 is attached has been described. The present invention is not limited to the above, but can be used, for example, between a windshield and a window frame to which the windshield is attached.

Further, in the present embodiment, the base 2
Although 2 has been shown as an example in which the wall thickness is gradually increased from the upper end to the lower end, the present invention is not limited to such an example. For example, the base 22 may be thick throughout the entire length from the upper end to the lower end, or only the lower end of the base 22 may be thick.

[0038]

Since the present invention has the above-mentioned structure, even if a force is applied to the peripheral molding of the window glass in the mounted state, the peripheral molding of the window glass does not rotate and warp does not occur.
