Abstract
A frame-attached window panel wherein a frame member comprises a base portion attached firmly to a peripheral portion of a window panel and a primary molding molded integrally with the base portion, and the primary molding is made of a material different from the material for the base portion. The generation of noises can be suppressed by the presence of the frame member which can be formed at low cost.
Claims9
A frame-attached window panel comprising:
- a frame member integrally molded to a peripheral portion of a window panel via an injection molding process, the frame member including:
- a base portion integrally molded to the peripheral portion of the window panel via the injection-molding process;
- and
- a primary molding integrally molded to the base portion via the injection-molding process, the primary molding being made of a material different from a material for the base portion.
A method for preparing a frame-attached window panel by molding a resinous material to form a frame member so as to be integral with a peripheral portion of a window panel and a primary molding, the method comprising the steps of:
- inserting the peripheral portion of the window panel and the primary molding, which has been previously formed, into a mold cavity of a mold apparatus;
- and
- injection-molding the resinous material into the mold cavity of the molding apparatus to form a base portion of the frame member between the peripheral portion of the window panel and the previously formed primary molding so that the base portion of the frame member is integrally molded to the primary molding and the peripheral portion of the window panel via the injection-molding.
