ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a ventilation system for a car window.
2. Description of the Related Art
As a known car window ventilation system of such a type, there have been a detachable car ventilation system in which a window panel integrally molded from plastics, or the like, and having a plurality of ventilating holes is put between a door sash frame and an upper end edge of window glass in a car so that natural ventilation to let fresh air in is performed (JP-A-2-220924); a car window ventilation system in which an exhaust fan is merely provided in a slight gap between a door sash frame and an upper end edge of window glass in a car (JP-U-6-55818); and so on.
These car window ventilation systems are, however, of the type in which a window panel is put between a door sash frame and an upper end edge of window glass in a car so that four sides of the window panel are not adjustable. Hence, there is a defect that the systems lack applicability to windows different in size and shape and to different types of cars. Furthermore, air exhausting only by means of a fan without use of natural ventilation to let fresh air in involves a defect that the capacity of ventilation is often insufficient.
In any of the related art, known ventilation systems, the ventilating member is constituted by a single layer filter. Hence, there is an inconvenience of invasion of dust or rainwater. Furthermore, the known ventilation systems were configured so as to be easily subjected to mischief from the outside. In addition, there was a risk that something might be thrown into the car from the outside through such airflow holes because of the shape of airflow holes in the related-art ventilating members.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a ventilation system for a car window which is configured such that the system can be widely applied to car windows different in size and shape or different types of cars; which is configured such that members such as a fan unit, etc. can be used in various combinations as constituent members of the system in accordance with a ventilating function so that the system can be flexibly adapted to user's option and dust, rainwater, or the like, can be prevented from invading the car from the outside directly; and in which the quantity of air flowing through airflow members can be adjusted.
The foregoing object is achieved by the invention defined in claims.
According to the present invention, the car window ventilation system can be adapted to user s option as to whether only a natural ventilation function is used to let fresh air in or a fan unit is additionally used to perform forced ventilation, whether a housing is provided with sunshade and weatherproof eaves or not, and whether a solar battery is used or a battery built in the car is used for actuating the fan unit.
Furthermore, when blocking plates which are portions for connecting a car window frame and an upper edge of window glass to each other (that is, adjustable blocking plates substantially as thick as the window glass) are formed by simply cutting a blocking plate material of transparent acrylic resin, or the like, having a predetermined thickness into predetermined contours while one and the same body housing is always used in the ventilation system, the ventilation system can be generally applied to windows different in size and shape and to cars different in types. Hence, the ventilation system can be attached to various types of cars because the ventilation system is not formed as an exclusive product which is produced by use of an expensive mold as in the related art and which can be applied to no car type but a specific car type. It is, however, a matter of course that final contour finishing of the blocking plates is performed by a cutting machine placed in a car window ventilation system maker, a car repair shop, or the like, because general users cannot finish such blocking plates.
Furthermore, when a cover plate is provided on a cover frame to which the airflow members are attached so as to be able to be opened/closed to adjust the quantity of air flowing through all the airflow members, a ventilating function can be given to the car window so that the quantity of air flowing through the car window can be adjusted.
Although the following embodiments show the case where the car window ventilation system according to the present invention is attached to a side door of a car, it is a matter of course that the ventilation system having the same configuration as described above can be applied also to a rear window of the car.
