Abstract

A method for producing a window glass for a vehicle provided with an ornamental braid comprises steps of setting an ornamental braid on a lower mold of an injection molding machine, fixing an ornamental braid connection member on the lower mold, setting a glass plate on the lower mold, closing an upper mold, thereby locking the molds, and injecting molten resin into a cavity formed between the lower mold and the upper mold, thereby integrally molding a resin frame, the ornamental braid and the ornamental braid connection member along a periphery of the glass plate.

Claims

1. A method for producing a window glass for a vehicle provided with an ornamental braid comprising steps of setting an ornamental braid on a lower mold of an injection molding machine, fixing an ornamental braid connection member on the lower mold, setting a glass plate on the lower mold, closing an upper mold, thereby locking the molds, and injecting molten resin into a cavity formed between the lower mold and the upper mold, thereby integrally molding a resin frame, the ornamental braid and the ornamental braid connection member along a periphery of the glass plate.

2. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of clamping the ornamental braid with the ornamental braid connection member and the lower mold, thereby fixing the ornamental braid on the lower mold.

3. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of clamping the ornamental braid with a plurality of projections formed on the ornamental braid connection member and the lower mold, thereby fixing the ornamental braid on the lower mold.

4. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of inserting a pin projecting from the lower mold into a hole formed in the ornamental braid connection member, thereby fixing the ornamental braid connection member on the lower mold.

5. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of engaging a plurality of projections formed on the ornamental braid connection member with a plurality of hollows formed on the lower mold, thereby fixing the ornamental braid connection member on the lower mold.

6. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, further comprising a step of engaging a plurality of hollows formed on the ornamental braid connection member with a plurality of projections formed on the lower mold, thereby fixing the ornamental braid connection member on the lower mold.

7. A method for producing a window glass for a vehicle provided with an ornamental braid of claim 1, wherein the ornamental braid connection member is provided with a hollow for engaging the resin frame.

8. A window glass for a vehicle provided with an ornamental braid comprising a resin frame, an ornamental braid, an ornamental braid connection member and a glass plate, wherein the resin frame, the ornamental braid and the ornamental braid connection member are integrally molded along a periphery of the glass plate.

9. A window glass for a vehicle provided with an ornamental braid of claim 8, wherein a hollow formed in the ornamental braid connection member engages a projection formed on the resin frame.
