ABSTRACT:
BACKGROUND OF THE INVENTION
The interior of an automobile is an almost closed space that becomes very hot and sweltering when sun light projects into it for a prolonged time. An in-car air-conditioning system might be useful in cooling the interior of the automobile. It cannot, however, stop the sun light from projecting into the automobile. There are various kinds of sunshades for automobiles available in the markets. A user may fix the sunshade to inner side of the windshield in order to prevent the sun light from directly projecting into the automobile. The sunshade has therefore become a necessary article in automobiles. Although these commercially available sunshades are differently structured and manufactured, they have a common disadvantage that they are manufactured in several separated stages instead of being produced on a continuous production line. As a result, the conventional sunshades suffer from an efficient production process. Moreover, these conventional sunshades are made of different materials and accordingly are different in their quality. A sunshade made of inferior material tends to deform and have a shortened usable life when the sunshade is subject to frequent folding or compressing. A deformed sunshade is unsightly and cannot be easily folded for convenient storage.
It is therefore desirable to develop a sunshade for use in an automobile to eliminate the drawbacks existing in the currently available sunshades.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a method for producing a sunshade for use in an automobile. The method includes continuous and consistent steps and therefore increases the efficiency in producing the sunshade.
Another object of the present invention is to provide a method for producing a sunshade which enables production of integrally molded sunshades for automobiles.
A further object of the present invention is to provide a sunshade that can be smoothly folded to a reduced volume without creating undesirable cracks that will shorten the usable life of the sunshade.
The method of the present invention for producing a sunshade for automobile includes the step of continuously feeding a resilient foamed plastic board or a composite material including a layer of such resilient foamed plastic board into an oven to heat the same in said oven, so that the resilient foamed plastic board becomes softened before the foamed plastic board or the composite material is fed into a molding press. The molding press is provided with a set of molding dies that are maintained at a controlled low temperature by cooling water supplied via pipes extended through the molding press, so that the resilient foamed plastic board or the composite material is pressed, cooled, and molded at a time to form a plurality of continuous primary sunshades. The continuous primary sunshades are cut apart and trimmed to provide finished individual sunshades. Each completed sunshade is provided at a surface with parallel and alternately arranged wider and narrower folding grooves. The wider folding groove has a width twice as large as that of the narrower folding groove, enabling the sunshade to be smoothly folded into a small volume for convenient storage without creating cracks that would adversely affect the appearance and the usable life of the sunshade.
