Description

The present invention relates to a glass run for guiding a windshield that moves up and down in an automobile door.

Generally, a side door provided on the side of an automobile includes a window glass that can be raised and lowered to open and close a window opening formed by a wind frame, and a glass run for sealing between the wind frame and the window glass. There is. There is a so-called hidden type glass run that is attached to the wind frame from the outside of the vehicle and covers and hides the upper part of the frame outside the vehicle. Such hidden type glass runs are sometimes adopted due to the design requirements of automobiles, for example. Similarly, due to design requirements, a garnish is sometimes provided on the outside of an automobile wind frame along the longitudinal side of the frame.

A structure in which a garnish is attached to an automobile employing a hidden type glass run as described above is disclosed in, for example, Patent Document 1. When attaching a glass run and a garnish to a wind frame in an automobile such as the one described in Patent Document 1, the upper extruded part of the glass run is usually first moved from the outside of the vehicle to the inside of the vehicle with respect to the flange of the upper side of the frame that protrudes toward the outside of the vehicle. Assemble towards. In this state, as shown in Figure 6, the vertical side extrusion overlaps the garnish attachment position in side view, so the operator bends the vertical side extrusion towards the upper side extrusion as shown in Figure 7 to attach the garnish. The garnish is fixed at the mounting position by exposing the fastening hole for passing the fastener, and fastening and fixing the garnish to the mounting position using a fastener such as a clip or screw. Thereafter, the longitudinal side extrusion part is assembled to the garnish and the frame longitudinal side part.

US Patent No. 9114765

When the vertical side extrusion part is bent toward the top side extrusion side when attaching the garnish as described above, the molding part that is the connection point between the vertical side extrusion part and the top side extrusion part, which is the starting point of bending, is usually placed on the inside wall of the car. is configured to have a large rigidity (details will be described later). For this reason, the operator requires a large amount of force for bending. In particular, when attaching the upper part of the garnish with fasteners, it is necessary to bend the lower part of the rear longitudinal side extrusion to the extent that it is located above the upper side extrusion, which increases the burden on the operator. Sexuality worsens. Further, there was also the problem that folds and wrinkles tend to remain on the molded part after assembly work, deteriorating the appearance.

The present invention has been made in view of the above-mentioned problems, and its purpose is to facilitate the attachment of a garnish to a wind frame to which a hidden type glass run is attached, and to prevent deterioration of the appearance of the molded part. It is about doing.

In order to achieve the above object, in the present invention, a molded thin part is provided in the molded part which is the connecting part between the upper side extruded part and the rear longitudinal side extruded part of the glass run.

Specifically, the grass run according to the present invention is
A window glass for opening and closing a window opening of the door, which is attached along the upper side of the frame of the window frame of an automobile door and the vertical side of the frame extending downward from the end of the upper side of the frame, and the window frame. It is a glass run that seals between
an upper extruded part that is extruded to extend along the upper side of the frame and is assembled to the upper side of the frame;
a vertical side extrusion part that extends downward from an end of the upper side extrusion part and is assembled to the vertical side part of the frame;
a molding part disposed between the upper side extrusion part and the longitudinal side extrusion part, and connecting the upper side extrusion part and the longitudinal side extrusion part,
The molding part is
a molded upper wall and a molded lower wall;
a molded connection wall connecting an outer side end of the molded upper wall and an outer side end of the molded lower wall;
a molded vehicle outer side wall extending from the vehicle outer side end of the molded lower wall toward the center side of the windshield;
a molded car inner wall extending from the car inner side end of the molded lower wall toward the center of the windshield;
a molded inner lip extending from an end of the molded car inner side wall toward a windshield corner end side;
a molded extension portion that extends continuously from an end of the molded car inner side wall toward the center of the windshield;
a molded molding lip that is bent from the molded extension part toward the inside of the vehicle, extends toward the windshield corner end side, and is assembled to the window frame;
A molded thin wall portion is formed in a portion between the molded inner lip and the molded molding lip in the molded extension portion.

According to the glass run according to the present invention, since the molded thin part is formed in the part between the molded inner lip and the molded molding lip in the molded extension part, the operator can attach the garnish to the rear side. When bending the vertical side extruded portion toward the upper side extruded portion, the rear vertical side extruded portion can be bent with a smaller force than conventionally. In particular, when fixing the upper part of the garnish to the wind frame, it is necessary to bend the rear vertical edge extrusion from its upper end toward the upper edge extrusion. At this time, the starting point of the bend is the part between the molded inner lip and the molded molding lip in the molded extension part, but since this part is thin, the operator can bend the rear longitudinal side extrusion part with a small force. Can be bent. Thereby, the operator can easily attach the garnish, that is, the workability can be improved, and folds and wrinkles are less likely to remain on the molded part, so that deterioration of the appearance can be prevented.

In the glass run according to the present invention, it is preferable that the thickness of the molded thin wall portion is thinner than the wall thickness of the molded car inner side wall. More preferably, the thickness of the molded thin wall portion is 40 to 60% of the thickness of the molded car inner side wall.

In this way, it is possible to sufficiently obtain the above-mentioned effect of improving workability, and at the same time, reduction in the strength of the glass run itself can be minimized.

In the glass run according to the present invention, the molded thin wall portion includes a boundary line between the extrusion molded inner lip and the extrusion molded stretched portion in the molded portion, and a boundary line between the longitudinal side extruded molded inner lip and the vertical side extruded molded stretched portion. It is preferable that the angle be provided at least on the bisector of the angle formed by the angle.

When you try to bend the rear vertical side extruded part from its upper end toward the upper side extruded part, the starting point of the bend is the boundary line between the extruded inner lip and the extruded stretched part in the molded part and the longitudinal side extruded inner Although it exists on the bisector of the angle formed by the lip and the boundary line of the longitudinal extrusion molding extension part, the existence of the thin part in this part sufficiently obtains the above-mentioned workability improvement effect. be able to.

In the glass run according to the present invention, the molded thin wall portion includes a boundary line between the extrusion molded inner lip and the extrusion molded stretched portion in the molded portion, and a boundary line between the longitudinal side extruded molded inner lip and the vertical side extruded molded stretched portion. The width is preferably 6 to 10 mm with the bisector of the angle formed by the center line as the center line.

In this way, the above-mentioned workability improvement effect can be sufficiently obtained, and since the molded thin wall part is not excessively wide, it becomes the starting point for bending the rear longitudinal side extrusion part, and can be bent with a small force. It is easy to bend, and it is possible to prevent the molded thin part from being torn and spoiling the appearance after the rear longitudinal side extrusion part is assembled.

According to the glass run according to the present invention, it is possible to easily attach the garnish to the wind frame in which the hidden type glass run is installed, and it is also possible to prevent folds and wrinkles from remaining on the molded part, thereby preventing deterioration of the appearance.

The molded thin wall portion 49 facilitates bending of the rear vertical side extruded portion 30 of the glass run 10 when attaching the garnish 70, and as a result, workability in attaching the garnish 70 can be improved. (Details below). However, if it is too thin, the rigidity of the glass run 10 will become smaller than necessary, and the molded thin wall portion 49 will break after it becomes the starting point for bending the rear vertical side extrusion portion 30, which may impair the appearance. , undesirable. On the other hand, if it is not sufficiently thin, the desired effect cannot be obtained, so for example, the thickness T3 of the molded thin wall portion 49 is preferably 40 to 60% of the wall thickness T4 of the molded car inner side wall 45.

Below, the effects of the grass run 10 according to this embodiment will be explained in more detail. As described above, when attaching the garnish 70 to the door 2 of an automobile that employs the hidden type glass run 10, the upper side extrusion part 20 is assembled to the frame upper side part 7, and then the garnish 70 is attached to the door 2, and then the vertical side The extrusion part 30 is assembled to the rear vertical side part 8 of the frame and the garnish 70. Here, the reason why the garnish 70 is not attached to the door 2 before the upper side extrusion part 20 is because if the garnish 70 is attached to the door 2 first, the upper side extrusion part 20 is attached from the outside of the vehicle to the inside of the vehicle. This is because the rear longitudinal edge extrusion portion 30 interferes with the garnish 70 when More specifically, when the upper side extrusion part 20 is assembled to the frame upper side part 7 as shown in FIG. 3, the rear vertical side extrusion part 30 is the attachment position of the garnish 70 as shown in FIG. It overlaps with the inclined plate 74. Further, as shown in FIG. 6, the top part of the screw B fastening hole 75 is at the height where the rear molded part 40 is arranged, which is the part above the upper end of the rear vertical side extruded part 30. ing. Therefore, in order to attach the garnish 70, the operator bends the garnish 70 extremely to such an extent that the lower part of the rear longitudinal side extrusion part 30 is above the upper side extrusion part 20, as shown in FIG. It is necessary to expose the fastening hole 75 of the inclined plate 74, which is the mounting position. After exposing the fastening hole 75, the garnish 70 is fastened and fixed to the inclined plate 74 at the mounting position using screws B. Thereafter, the rear vertical side extruded part 30 is assembled into the attachment groove formed by the garnish 70 and the frame rear vertical side part 8.

As shown in FIG. 7, when the rear vertical side extruded part 30 is bent toward the upper side extruded part 20 when attaching the garnish 70, a molded part existing at the upper end of the rear vertical side extruded part 30, which is the starting point of bending. 40 is configured to have lower rigidity than the rear vertical edge extruded portion 30, as described above. Therefore, normally, the operator needs a large force to bend the rear vertical side extrusion part 30, which puts a burden on the operator, but in this embodiment, as described above, the molded part Since the die-molded thin wall portion 49 is provided in the portion, the rigidity of the portion is partially reduced. Therefore, the burden on the worker can be reduced.

In this embodiment, when attempting to bend the rear vertical side extruded portion 30 from its base end toward the upper side extruded portion 20 in order to fasten the upper end portion of the garnish 70 with screws B etc., the bending starting point is Bisection of the angle formed by the boundary line K1 between the extrusion molded inner lip 27 and the extrusion molded extension part 25a in the molding part 40 and the boundary line K2 between the vertical side extrusion molded inner lip 35 and the vertical side extrusion molded extension part 32a Since the molded thin part 49 is present near the line, it is preferable that the molded thin part 49 be provided in this part. As shown in FIG. 8, in the molding part 40, a boundary line K1 between the extrusion molded inner lip 27 and the extrusion molded extended part 25a, and a boundary line K2 between the vertical side extruded molded inner lip 35 and the vertical side extruded molded extended part 32a. The bisector of the angle formed by the boundary line K1 between the extrusion molded inner lip 27 and the extrusion molded extended part 25a in the molded part 40 of the glass run 10 and the vertical side extruded molded inner lip 35 and the vertical side extruded molded stretched part It is a straight line that bisects the angle formed by the boundary line K2 with 32a, and is a straight line L that connects the outer corner M1 and the inner corner M2. By providing a molded thin part 49 between the molded inner lip 47 and the molded molding lip 48 at least on this straight line L, the rear vertical side extruded part 30 is bent from its upper end toward the upper side extruded part 20 side. It is possible to reduce the burden on the worker during the process. Preferably, as shown in FIG. 8, the molded thin portion 49 is provided in a range W that extends in both directions (width direction) with the straight line L as the center line. If the range W is too small, the desired effect cannot be obtained, and if the range W is too large, the strength of the glass run 10 will be reduced. Therefore, for example, the length of W is preferably about 6 to 10 mm.

Although the present embodiment has been described using the glass run 10 in the front door 2 as an example, it is of course possible to apply the present invention to other parts such as the rear door 80 where the glass run 10 and the garnish 70 are provided.

As described above, the glass run 10 according to the present invention is extremely useful because it can improve the workability when attaching the garnish 70.
