Description

TECHNICAL FIELD The present invention relates to a window regulator suitable for use in, for example, a front door of an automobile.

BACKGROUND ART Wind regulators for raising and lowering windshields of automobiles are roughly classified into arm type and cable type. The cable type is a moving direction of a carrier plate mounted with the windshield substantially hanging from its center of gravity. Is regulated by a guide for the carrier plate (hereinafter referred to as a guide),
The windshield is moved up and down by moving the carrier plate in the vertical direction along the guide, and there is no structural difference between the front door and the rear door.

On the other hand, in hard-top passenger cars that do not have a wind frame, a glass guide is provided inside the door and, in some cases, at the top of the door to stabilize the holding of the glass, and when the glass is closed, the front edge of the windshield for the rear door is closed. The watertightness between the windshields for the doors is maintained by crimping the rear edge of the windshields for the front doors to the weather strips attached to the parts.

Also, with a carrier plate fitted with wind glass,
It has a guide rail for guiding the carrier plate in the vertical direction, and in the vicinity of the carrier plate rising limit position,
A device in which the carrier plate can be pressed in the front-rear direction according to the rise of the carrier plate is shown in Japanese Utility Model Laid-Open No. 60-46779.

The problem to be solved by the invention is, however, that when the glass guide is provided only on the front side of the door and the cable type window regulator is used to move up and down the windshield for the front door of the hard top passenger car, the windshield for the front door moves the front side. Although the rear side is held by the guide for the carrier plate by the guide for glass, due to the gap generated between the guide for carrier and the carrier plate, the rear edge portion of the windshield for front door mounted on the carrier plate It has been difficult to strongly press-bond to the weather strip attached to the front edge of the rear window glass, and it is not possible to obtain sufficient watertightness between these window glass for doors.

In addition, the one described in Japanese Utility Model Laid-Open No. 60-46779 raises the window glass in a curved manner by a pair of guide rails different from the guide rails that guide the carrier plate when the carrier plate is raised with respect to the guide rail. I was just trying to do it.

The object of the present invention is to solve the above-mentioned problems, and when the carrier plate is raised with respect to the guide, the roller moves upward along the guide as the carrier plate rises, and the outer circumference of the roller raises the carrier plate. Along with this, the pressing portion of the regulating body slides, and the pressing portion of the regulating body presses the carrier plate through the roller toward the windshield with the weatherstrip attached to the edge, and the gap generated between the carrier plate and the guide. And press the edge of the other windshield strongly against the weatherstrip on the edge of the windshield as the carrier plate rises, and get enough watertightness between the windshield and other windshield It is to provide a possible window regulator.

Means for Solving the Problems A window regulator according to the present invention is a window plate having a weather strip attached to an edge portion thereof, and a carrier plate having another window glass having an edge portion adjacent to the weather strip, and the carrier. In a window regulator having a guide for slidingly fitting a plate and guiding it linearly in the vertical direction, a roller is rotatably provided on the carrier plate, and the guide plate is provided in the vicinity of a rising limit position of the carrier plate. A regulation body that is in sliding contact with the roller is provided, and an edge portion of the other windshield is pressure-bonded to the regulation body via the roller toward the weather strip on the edge portion of the wind glass according to the rise of the carrier plate. It has a configuration characterized in that a pressing portion is formed.

Action When the carrier plate rises with respect to the guide, the roller moves upward along the guide as the carrier plate rises, and the outer circumference of the roller slides against the pressing portion formed on the regulation body as the carrier plate rises and regulates. The pressing part of the body presses the carrier plate through the roller toward the windshield with the weatherstrip attached to the edge, and the edges of the other windshields weather the edge of the windglass as the carrier plate rises. Crimp towards the strip.
