Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a protective molding used for decoratively concealing the peripheral edge of an automobile window frame, particularly the gap formed between the windshield peripheral edge and a body panel plate.

FIG. 1 is a cross-sectional view illustrating the state in which such a conventional protective molding is used, and FIG. 2 is a partial view of the front of an automobile, showing an example of the area in which this protective molding is used.

In the diagram, 1 is the protective molding, 2 is the windshield, and 3
1 is a body panel, and line A-A shows the cross-sectional view of FIG.

The body panel 3 in FIG. 1 includes a mounting part 5 in which a window frame opening 4 is formed, a flat part 6 bent outward from the mounting part 5, and a body part 7 further bent from the flat part 6. It is made up of.

A dam rubber 8 is adhered to the entire circumference of the windshield 2, that is, the shield glass, at a constant width from the periphery of the windshield 2, and an adhesive 9, that is, urethane sealant is attached in advance to the outer peripheral surface of the dam rubber 8 in contact with the dam rubber 8. The opening is closed by press-bonding the windshield 2 to the mounting portion 5 of the body panel 3, and the windshield 2 is fixed to the mounting portion 5 as the adhesive 9 hardens naturally.

In the example shown in FIG. 1, the protective molding 1 is fitted onto the outer circumferential edge surface 2a of the windshield 2 either immediately after or before the adhesive 9 is attached.

That is, this protective molding 1 has an elongated molding part 1a, and the molding part 1a extends from the center of the back surface of the protective molding 1.
It consists of a body part 1b which is bent in only one direction and has a holding part 1c that can hold the outer peripheral edge surface 2a of the windshield 2 along the same line, and a plurality of legs 1d, 1d derived from the body part 1b. . Since this was press-adhered to the mounting portion 5 with the holding portion 1c fitted onto the windshield outer peripheral edge surface 2a in advance, the spacing between the gaps 10 may vary depending on the adhesion dimensions of the windshield 2. Therefore, the molding part 1
There have been cases in which assembly defects have occurred due to dimensional errors in the manufacturing process of the windshield 2, incorrect mounting position of the windshield 2, and the like.

For this purpose, a protective molding 11 as shown in FIG.
was proposed.

That is, the main protective molding 11 includes a molding part 11a molded into a long shape from a resin material, and a molding part 1.
Consisting of a body part 11b extending from the center of the back surface of the body part 1a, a plurality of legs 11c, 11c... derived from the upper and lower surfaces of the body part 11b are integrally formed with a shape slightly shorter than the length of the molding part 11a. Molded.

This protective molding 11 is made by press-bonding the windshield 2 to the mounting part 5 with adhesive 9 in advance, and then pressing it into the cavity 10 from the body part 11b.
The tip of the body portion 11b was brought into contact with the adhesive 9 and fixed.

However, even if the protective molding 11 is pressed,
At this point, the adhesive 9 does not have sufficient softening properties and the surface is in the stage of hardening, and the body 11b rebounds outward against the pressing force due to the reaction force of the adhesive surface. Protective molding 1 as shown by the dotted line
1' is easily pressed.

This is because the body portion 11b is difficult to adapt to the adhesive 9, and at the same time, the surface of the flat portion 6 and the legs 11c become slippery due to the reaction force of the protective molding 11.

The present invention was developed to eliminate these drawbacks, and its purpose is to sufficiently absorb the dimensional error in the gap between the shield glass and the body panel, thereby making it easier to install the protective molding. To provide a protective molding characterized by integrally molded with a resistor that can absorb the repulsion force of an adhesive even during bonding without variation.

Hereinafter, the protective molding for the periphery of an automobile window frame according to the present invention will be explained with reference to FIG.

FIG. 2A shows an example of a perspective view of the protective molding 20, which is made of a relatively soft synthetic resin material, such as 12 nylon, by extrusion molding using an extrusion molding machine.

That is, the protective molding 20 is an elongated body formed by extrusion molding, and includes a molding body 21 having a curved surface, and a thickness of the molding body 21 that extends from the center of the back surface of the molding body 21 along the length direction of the molding body 21. It consists of a body long part 22 having approximately the same thickness.

The body length portion 22 extends linearly, and the tip portion 23
is formed into a pointed shape, and the windshield 2
From the end face of the body panel 3 and the flat part 6 of the body panel 3 and both sides of the body length part 22 corresponding to each other, that is, from the upper and lower surfaces of the body body part 22 in the illustrated example, a flexible part thinner than the thickness of the body body part 22 extends out. The legs 24, 24...
are formed from the same position, two parallel each on the upper and lower sides,
Its width dimension is shorter than that of the molding part 21.

As already mentioned, the legs 24, 24, . . . are configured to be easily bent when they come into contact with other objects.

And the tip portions 24a of the legs 24, 24,
The leg bodies 24, 24a are made of a material different from that of the molding body 21, that is, a material having a large coefficient of friction, such as elastomer material such as urethane or rubber, and are formed by double molding the resistors 25, 25 in the same extruder. It is integrally constructed along 24.

Although the resistors 25, 25 are formed in the direction of the molding body 21, there is no problem if they are formed in the opposite direction.

FIG. 4b shows another embodiment, in which the resistors 25a, 25a are extended to the legs.

That is, the leg body and the resistor body are integrally molded from the same material, elastomer, and the tip portion 23 is not linearly pointed but bent to one side.

The protective molding 20 of the present invention configured as described above
To explain in detail the action when assembling into the window frame,
In FIG. 5, the body panel 3 is composed of a mounting part 5 in which a window frame opening 4 is formed and a flat part 6 bent outward from the mounting part 5, and the windshield 2 has a dam rubber 8. The windshield 2 is bonded to the entire circumference at a constant width from the periphery of the windshield 2, and an adhesive 9 made of urethane sealant is applied to the outer peripheral surface in contact with the dam rubber 8.
The adhesive 9 is pressed and bonded to the mounting portion 5 of the body panel 3 by pressing the adhesive 9.

At this time, the windshield 2 is attached because the adhesive 9 is strong despite its own weight.
It is fixed with a gap 10 having a substantially constant width formed between the flat part 6 and the flat part 6.

After such a state is established, the protective molding 20 is inserted into the cavity 10.

The protective molding 20 is inserted in the direction of the long body part 22 before the adhesive 9 has completely hardened. Insert tip 23
Continue until it comes into contact with the adhesive 9 and is further inserted into the interior.

At this time, the adhesive 9 generates a repulsive force against the other object due to its high viscosity, and tries to push back the protective molding 20 itself, which is the other object, to the outside. At the same time, the resistors 25, 25 integrally molded at the tips of the legs 24, 24 come into close contact with the flat part 6, and the movement of the protective molding 20 is prevented by resistance force, that is, frictional resistance.

This frictional resistance prevents the protective molding 20 from slipping and makes it stand still, and the tip 23 inserted into the adhesive 9 is fixed by the adhesive 9.

As explained above, the present invention provides a protective molding for the periphery of an automobile window frame that is inserted and fixed in the gap between the end face of the automobile window glass and the body panel surface, and has a width larger than the gap. a molding body for closing the front surface of the cavity, a long body portion that intersects with the back surface of the molding body and protrudes from a substantially central portion of the rear surface of the molding body to be inserted into the cavity, the end surface of the glass; In order to come into relative contact with the body panel surface, legs protruding from both sides of the long body portion corresponding to the glass end surface and the body panel surface are integrally formed of a synthetic resin material. A resistor made of a material with high frictional resistance is integrally formed at the tip of the leg corresponding to the panel surface.

In the case of the present invention, a resistor with high frictional resistance is integrally formed at the tip of the leg of the protective molding, and when the protective molding is inserted into a predetermined gap, the resistor hits a predetermined part of the body panel. Because it comes into contact with the surface and increases the stability of the protective molding insertion state,
Until the adhesive for fixing the protective molding, that is, the sheetant, hardens, the protective molding can be stably held in place without any unwanted movement, and as a result, the position of the protective molding can be corrected. This eliminates unnecessary work and increases work efficiency.
