DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding glass window for a vehicle which is slidably mounted on a window opening of the vehicle.

[0002]

2. Description of the Related Art There are two types of glass windows for automobiles, one fixed to a window opening of an automobile and one slidably attached to the window opening. A glass window fixed to a window opening of an automobile is provided with a molding (frame material) on a peripheral portion of a glass plate. Conventionally, several methods have been proposed for providing a frame material on the periphery of a glass plate. For example, Japanese Patent Application Laid-Open No. 2000-79626 discloses that a surface of a frame material injection-molded in a mold is exposed from the mold, and the frame material is protruded from the mold by a projecting pin to form a glass plate. A method of bonding to a peripheral portion of a vehicle inner side surface is disclosed. According to this method, even if the glass plate is curved, the frame material can be firmly and accurately bonded to the glass plate using an inexpensive mold.

A glass window slidably attached to a window opening of an automobile is applied to, for example, a door.
An automobile door includes a glass plate that opens and closes a window opening, a door body that is disposed adjacent to the window opening and has a storage unit that can store the glass plate, and a glass plate that is placed between the window opening and the storage unit. And a window regulator (moving means) for moving the object. Some window regulators include a motor (driving means) and a rack and pinion mechanism interposed between the motor and the glass plate.

[0004]

Generally, a window regulator has a complicated structure and a large number of parts. Therefore, it is desired to simplify the structure of the window regulator. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sliding glass window for an automobile that enables simplification of the structure of a window regulator and the like.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a sliding glass window for an automobile in which a resin rack is integrated over substantially the entire rear side of a glass plate.

In this specification, “front”, “rear”, “up”, “down”, “inside”, and “outside” used to represent directions and positions are as follows.
It means "front", "rear", "up", "down", "inside" and "outside" when the sliding glass window for an automobile is attached to the body of the vehicle.
The expression “approximately the entire area on the rear side of the glass sheet” means that the predetermined opening and closing movement of the glass sheet with respect to the window opening can be ensured, but the area does not cover the entire area on the rear side of the glass sheet. As the material of the resin rack, the hardness (Hs) measured by a spring hardness test (A type) specified in JIS K6301 can be used.
A) 90 or more, more preferably 99 or more can be adopted, and examples thereof include hard vinyl chloride resin and propylene resin. Examples of the glass plate include a single glass plate and a laminated glass. As the glass plate, other than a transparent or translucent one, a chromatic color can be used as long as it has sufficient transparency. Further, the glass plate may be provided with a functional coating such as a strengthening treatment or a heat ray reflective film.

[0007] The sliding glass window for an automobile as described above is formed by engaging an integrated resin rack with a pinion rotated by a motor of a window regulator.
The window opening can be opened and closed. Therefore, the structure of the window regulator is simplified.

In the present invention, after a resin material is injected into a mold to form a resin rack, the mold is opened to expose the surface of the resin rack bonded to the glass plate to the outside. It is preferable that the resin rack is integrated with the rear side of the glass plate by placing the glass plate facing the rack, and then projecting the resin rack from the mold and pressing it against one surface of the glass plate. In order to ensure smooth opening and closing movement of the glass window for the vehicle with respect to the window opening, it is necessary to accurately attach the resin rack to the glass plate. Performing this attachment manually is complicated. Therefore, as described above, the resin rack is protruded from the mold and pressed against one surface of the glass plate on the glass plate accurately placed at a predetermined position with respect to the mold by the transfer device. Can be accurately, easily and quickly attached to a glass plate.
