BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window glass peripheral molding molded from a synthetic resin, which is mounted along the peripheral portion of an automobile window glass.

[0002]

2. Description of the Related Art An automobile window glass peripheral molding covers a gap between a window opening and a peripheral portion of the window glass accommodated in the peripheral molding to prevent rainwater, dust, and the like from invading the window glass while the window glass is accommodated. It has the meaning of adjusting the hidden appearance. Conventionally, a metal strip having an arc-shaped cross section has been used for this peripheral molding. This metal molding is difficult to process itself, and at the same time, it is not easy to install along the curved line of the window opening, the workability is poor, and there are problems such as stains due to rusting. It was Because of this, it has excellent manufacturability,
An easy-to-handle synthetic resin peripheral rim has been developed and is now being used in many vehicles. Many of the synthetic resin peripheral rim moldings have means for mounting them on the molding itself, and those that can be mounted by inserting the engagement leg pieces into the gap between the peripheral edge of the window glass and the window glass. Preliminarily fitted to the periphery and attached to the opening of the window when the window glass is attached, or a strip-shaped clip molded of the same synthetic resin is fastened along the opening of the window and attached to this clip. Various types have been proposed and put into practical use, such as locking between the window opening and the window glass by locking.

[Problems to be Solved by the Invention] Although the peripheral resin moldings made of synthetic resins according to the above-mentioned proposals are excellent in moldability and workability,
On the other hand, there is a problem that the dimension changes in the longitudinal direction after molding, mainly shrinkage, and in the mounted state, there is a problem that a gap is often generated at the corner portion of the window opening and the abutting joint portion between the end portions. Possible causes of this shrinkage change are release of residual stress during extrusion molding, divergence of plasticizer, linear expansion, change of water absorption, change of crystal ratio, etc. However, there is no effective solution for other causes, and as a result of the actual length of use, a fixed length cut followed by fastening along the window opening causes contraction, resulting in the above-mentioned problem. Sometimes caused problems. Of these causes of shrinkage, the expansion and shrinkage due to temperature change is a big problem, and when used with a length of several meters along the window opening, there is a change of several millimeters, which may not be negligible.

As a method for improving this, it has been proposed to embed a reinforcing metal thin film. However, in addition to being a thin film, since it is merely embedded, it lacks the integrity with the resin, and the peripheral molding It was still in an insufficient state to suppress the expansion and contraction change. The present invention has been researched and developed in order to improve the elasticity of a peripheral molding formed by using such a synthetic resin as a base material, and the main object is to expand and contract the peripheral molding made of synthetic resin. It is intended to provide a peripheral edge molding for a window glass of an automobile, which suppresses the rise, rises from the window glass peripheral portion, the window opening portion, and the cutting of the abutting portion of the joint portion and enables stable mounting. Is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of a peripheral molding according to the present invention before use, and FIG. 2 is a sectional view showing a mounted and used state. The peripheral molding 1 of the present invention shown here is of a type to be mounted in combination with the clip 2, and the clip 2 is previously attached to the rising wall portion 4 of the window opening 3 of the body, and the clip is used as a scaffold. It has a structure to be attached.

The peripheral molding 1 has a head portion 1a in the form of a slightly thick band plate, a leg portion 1b hanging from a substantially central portion of the lower surface of the head portion 1a, and one side from the leg end portion of the leg portion 1b. Glass locking piece 1c extending in a folded shape to the first and second locking pieces 1 extending from both side surfaces in the middle of the length of the leg portion 1b.
d and 1e are integrally formed, and a strip-shaped reinforcing core 5 having a width occupying substantially the entire length of the leg 1b is integrally embedded in the center of the leg 1b over the entire length. I am doing it.

The peripheral molding 1 is formed by extruding a thermoplastic synthetic resin having appropriate rigidity and flexibility such as nylon, and the left and right edge portions of the head 1a are thin tongue pieces. Flexibility is imparted to the window glass 6 and the surface portion 7 of the window opening (which is the surface of the clip 2 in this embodiment) so that the window glass 6 and the surface portion 7 can be closely attached. And
The leg portion 1b is formed in a substantially flat plate shape along the entire lower surface of the head portion 1a.

The reinforcing core material 5 is embedded over the entire length of the height of the leg portion 1b, and the upper end portion thereof reaches the head portion 1a. This reinforcing core material 5 is intended to reinforce the rigidity of the peripheral molding, and at the same time, to suppress and stabilize expansion and contraction under the influence of changes in atmospheric temperature, heating by direct sunlight, etc. Then, as shown in FIG. 5, a metal strip,
More specifically, a strip of aluminum is used as a base material, and a large number of wavy concavities and convexities 9 are provided in rows on both sides of a strip-shaped core material by embossing with a pressing machine in the longitudinal direction. When the peripheral molding 1 is extruded, the peripheral molding 1 is simultaneously embedded along the center of the leg 1b so that the resin can flow between the irregularities 9 to be integrated with the leg.

The reinforcing core material 5 is formed to have irregularities on both sides by mechanical processing so as to be integrated with the leg portion 1b in a buried state. Further, the core material 5 (made of aluminum) is used. The surface may be preliminarily coated with a salt-vinyl acetate based coating agent so as to be integrated with the leg portion 1b at the time of burying, and the core material and the peripheral molding body are mechanically and chemically integrated with each other. Does not prevent things.

For the peripheral molding 1 thus formed, the clip 2 is molded from the same synthetic resin material. In this case, one side of the main body formed in the shape of a strip is provided with the second molding of the molding. Upper and lower claws 10 and 11 for hooking the stopper 1e
And a pressing piece 12 for pressing the lower end of the leg portion 1b of the molding, and a double-sided adhesive tape 13 for fixing the clip to the rising wall portion 4 of the window opening on the other surface. Then, a reinforcing core material 5 similar to that embedded in the leg portion 1b of the peripheral molding is embedded in the central portion of the main body over the entire length to suppress the expansion and contraction change of the clip. The peripheral molding described above fixes the window glass 6 to the window opening 3 through the sealant 14, and before the sealant is solidified, the leg portion is passed through the gap 15 formed between the window glass 6 and the window opening 3. 1b is inserted and locked.

The clip 2 is attached to the wall portion 4 via the adhesive tape 13 prior to the fitting of the window glass 6, and the second locking piece 1e which is intruded by the pushing of the leg portion 1b is clawed. 10 (or claw 11) to restrain the rising of the peripheral molding, while pressing the pressing piece 12 against the leg end of the leg portion 1b and pushing back with the spring force of the material, the glass locking piece 1
It will be urged so that c is pressed against the lower surface of the window glass 6. The peripheral edge molding 1 hooked via the clip 2 is inserted without backlash by bringing the other first locking piece 1d into contact with the edge of the glass 6 by the repulsive force of the second locking piece 1e, Further, the leg end and the glass locking piece 1c extending from this are pushed into the sealant 14 before being solidified, and are integrally bonded together with the window glass. Then, the glass locking piece 1c goes around the lower surface of the window glass 6 and is locked by this.

Next, FIGS. 3 and 4 show another embodiment in which the shapes of the peripheral molding 21 and the clip 22 are changed. The molding 21 shown here is a strip-shaped head 21a.
A pair of leg portions 21b and 21c are provided in a substantially parallel manner from the bottom surface of the clip 22, while the clip 22 is formed by extending a locking claw piece 23 from one end of the window opening portion 3 which is deeply inserted. It is as a thing.

In the molding 21, a claw 24 is provided in a stepped manner on the inner surface of one leg 21c, and a claw 25 of a locking claw piece 23 is hooked and coupled, while the sealant 1 is attached to the tip of the other leg 21b.
There is provided a claw 26 which is pushed into 4 to strengthen the connection therewith. The molding 21 and the clip 22 are formed by extruding nylon as a material, and the reinforcing core material 5 described in the above embodiment is integrally embedded in the molding 21 at the center of the leg 21b over the entire length. Further, the reinforcing core material 5 is embedded in the clip 22 over the entire length at the center of the main body portion along the rising wall 4.

In this embodiment, the peripheral molding is attached to the rising wall portion 4 of the window opening 3 in advance through the adhesive tape 13 attached to one surface of the clip 22, and then the sealant 1 is attached.
The window glass 6 fitted into the window opening by 4 is adhesively fixed, and before the sealant 14 is solidified, both leg portions 21b of the molding 21 are passed through a gap 15 formed between the window glass and the rising wall 4 of the window opening. 21c is inserted, one leg 21c is hooked on the locking claw piece 23, and the other leg 21b
The mounting will be completed by embedding in the sealant 14. Reference numeral 27 in the drawings is a dam rubber that prevents the sealant 14 from flowing out.

[0016]

The present invention is constructed as described in the above embodiments, and is applicable to a peripheral molding or clip molded from a thermoplastic synthetic resin such as nylon resin.
Since a reinforcing core material made of metal such as aluminum alloy having a linear expansion coefficient smaller than that of synthetic resin over the entire length is embedded integrally, it is possible to change the temperature of the conventional synthetic resin by changing the temperature. There is an advantage that it does not change in expansion and contraction like a peripheral molding and has excellent stability. In particular, since the reinforcing core material according to the present invention has corrugations on both sides along the longitudinal direction, when it is embedded in the peripheral molding, resin flows between the concavo-convex portions and integration of the resin is prevented. Therefore, the expansion and contraction of the peripheral molding can be completely prevented. Therefore, it is possible to provide a highly reliable peripheral molding without causing the connection abutting parts to separate from each other in the use state or disturbing the contact surface with the window glass to cause the floating appearance to be deteriorated.
