Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automobile door, and more particularly to a guide structure for a door glass with a small lap margin in the height direction.

[0002]

[Prior art]

 Conventionally, an automobile door is constructed, for example, as shown in FIG. That is, an automobile door 1 is attached to a vehicle body (not shown) via a hinge so as to be openable and closable, and a door supported on the door body 2 so as to be substantially vertically openable and closable. It is composed of glass 3.

The door glass 3 is sandwiched from the front and the rear by the guide frames 4 and 5 having a “U” -shaped cross section, which extend substantially vertically in the front and the rear in the door body 2, and thus the door glass 3 is vertically moved. It is supported so that it can slide in any direction. Here, in the case shown in the figure, since the lap margin a of the trailing edge of the door glass 3 with respect to the guide frame 5 is relatively small, the trailing edge of the door glass 3 is suppressed in order to suppress the swing of the door glass 3 in the width direction of the vehicle. Is equipped with a guide piece 6.

As shown in FIG. 7, the guide piece 6 has a substantially “U” -shaped cross section so as to cover the outer surface and the inner surface of the door glass 3 at the rear edge of the door glass 3, for example, a hightrail. Is formed of an elastic material such as, and further, the outer and inner surfaces of the guide frame 5 which come into contact with the inner wall of the guide frame 5 are formed so as to project as the contact portions 6a and 6b.

The guide piece 6 thus configured can be fixedly held on the rear edge of the door glass 3 by an adhesive or the like as shown in FIG. When attached, the contact portions 6a, 6b on the outer and inner surfaces of the guide piece 6 abut against the inner wall of the guide frame 5 as shown in FIG. 7, whereby the guide piece 6 is vertically slidably held along the guide frame 5. In addition, as shown in FIG. 8, when there is a shake in the width direction of the vehicle (arrow direction), the contact parts 6a and 6b are bent so that the shake is suppressed.

[0006]

[Problems to be solved by the device]

 However, in such a door glass guide structure, a so-called squeak called "cue" is generated when the door glass 3 is opened and closed due to a high friction coefficient of the elastic material forming the guide piece 6 especially at high temperature. May come to do. For this reason, the friction coefficient of the guide piece 6 with respect to the guide frame 5 is reduced by coating the inner surface of the guide frame 5 with, for example, molybdenum disulfide in advance. There was a problem that the comparative cost would be high.

Therefore, it is conceivable that the guide piece 6 itself is formed of a material having a small friction coefficient such as polyacetal. However, such a material has a small elasticity, and accordingly, the width of the door glass 6 of the automobile is small. When there is a shake in a direction, it is impossible to absorb this shake due to elastic deformation, and there is a problem that plastic deformation and cracks occur.

In view of the above points, the present invention can surely absorb the vibration of the door glass in the width direction of the vehicle, and lower the coefficient of friction with respect to the guide frame to suppress the squeaking at high temperatures. It is an object of the present invention to provide a door glass guide structure which has a simple structure and can be reduced in cost.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, an automobile door according to the present invention comprises a door body, guide frames extending substantially up and down in front of and behind the door body, and the guide frame. A door glass that is sandwiched from the front and back and is slidably supported in the vertical direction, and a "U" shape that is installed so as to cover the outer surface and the inner surface of the door glass at the front edge or the rear edge of the door glass. The guide piece is formed of an elastic material including a guide piece, and the outer and inner surfaces of the guide piece that come into contact with the guide frame are covered with a material having a small friction coefficient.

[0010]

[Action]

 According to the above configuration, when the door glass is attached to the door body, the outer surface and the inner surface of the guide piece come into contact with the inner wall of the guide frame through the material having a small friction coefficient. As a result, the door glass is vertically slidably sandwiched along the guide frame, and the vibration in the width direction of the vehicle is reliably absorbed due to the elastic deformation of the guide piece. Furthermore, since the friction coefficient against the guide frame is small even at high temperatures, squeaking does not occur, and unlike the conventional case, molybdenum disulfide coating is unnecessary.

[0011]

【Example】

 Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. FIG. 1 shows an example of a guide piece used in the door glass guide structure according to the present invention. The guide piece 10 has a substantially U-shaped cut surface so as to cover the outer surface and the inner surface of the door glass 3 at the rear edge of the door glass of the automobile (see FIG. 3). It is made of a material, and the outer and inner surfaces of the guide frame 5 that come into contact with the inner wall of the guide frame 5 are integrally formed so as to project in a bridge shape as the contact portions 11 and 12.

At least the surfaces of the contact portions 11 and 12 are covered with a material 13 having a small coefficient of friction such as polyacetal. In the case shown, the contact parts 11, 12 are provided with notches 11a, 12a in their most projecting central parts, and the material 13 is wound in the region of these notches 11a, 12a. It is integrally formed as described above.

The door glass guide structure according to the present invention is constructed as described above, and when the guide piece 10 is fixedly held at the rear end of the door glass 3 and the door glass 3 is attached to the door body. First, as shown in FIG. 3, the contact portions 11 and 12 on the outer and inner surfaces of the guide piece 10 come into contact with the inner wall of the guide frame 5 through the material 13 having a small friction coefficient. Therefore, the door glass 3 can be vertically slidably held along the guide frame 5.

Here, when the door glass 3 shakes in the width direction of the vehicle, the contact portion 11 or 12 of the guide piece 10 has a bridge shape in addition to the elasticity peculiar to the material as shown in FIG. In addition, it is elastically deformed based on the elasticity due to the shape, and the shake can be surely absorbed.

Further, since the contact portions 11 and 12 are in contact with the inner wall of the guide frame 5 through the material 13 having a small friction coefficient, the friction coefficient with respect to the guide frame is small even at a high temperature. There is no squeal when the door glass 3 is opened or closed.

[0016]

[Effect of device]

 As described above, according to this invention, when the door glass is attached to the door body, the outer surface and the inner surface of the guide piece come into contact with the inner wall of the guide frame through the material having a small friction coefficient. Thus, the door glass can be vertically slidably held along the guide frame, and the vibration of the vehicle in the width direction can be reliably absorbed by the elastic deformation of the guide piece. Furthermore, even at high temperatures, the squeal does not occur due to the small friction coefficient against the guide frame, and since the coating of molybdenum disulfide is not required as in the past, a simple process is used. It can be produced at low cost. Thus, according to the present invention, the door glass guide structure that can reliably absorb the vibration of the door glass in the width direction of the vehicle and can suppress the squeaking at high temperature by lowering the friction coefficient with respect to the guide frame is simple. It has a simple structure and is provided at low cost.
