Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip end mounting structure to be installed along a door opening of an automobile body or along an outer periphery of the door.

[Prior Art] A weather strip of this type is generally an extruded body having a hollow seal portion, and its end is connected to a die-molded end portion having a shape along a body panel surface or a door panel surface. Is fixed to the panel with screws or other means (Shokai 61-42321).

For example, in the hard top type automobile shown in FIG. 8, a hollow weather strip that seals the outer periphery of the door glass is attached to the roof side 1 along the roof side 1. At the end of this weather strip, for example, the rear end A, as shown in FIG. 9, at the end of the extrusion-molded weather strip 4,
The terminal portion 5 is formed by molding. A plate-shaped reinforcing insert 6 is embedded in the terminal portion 5. And the ninth
As shown in FIG. 10 and FIG. 10, the terminal portion 5 is fixed to the body panel 2 with screws 7 at a plurality of places via inserts 6.

In this case, it takes time to accurately position the terminal portion 5 and to fasten the screws at a plurality of places, and workability is not good. Further, the screw tightening point must be a place avoiding the seal line S with the mating member that comes into contact with the terminal portion 5, in this example, the peripheral edge portion of the door glass. Therefore, the screw tightening location is restricted. Therefore, it is possible to tighten the screw only at one location, but at one location, the edge of the terminal portion 5 rises and the entire terminal portion 5 is rotationally deformed when the screw is tightened, resulting in poor sealing performance. It took time to correct the deformation of the terminal unit 5 or the deformation of the terminal unit 5.

[Problems to be solved by the present invention] Therefore, according to the present invention, positioning of a body or a door with respect to a panel is easy, and a stable mounting state can be obtained by tightening a screw at one place, and a terminal portion is provided at the time of screw tightening. It is an object of the present invention to provide a weatherstrip terminal mounting structure which does not rotate and which has good mounting workability.

[Means for Solving the Problem] In the present invention, as illustrated in FIG. 1 to FIG. 3, the reinforcement insert 6 embedded in the terminal portion 5 is provided with a protrusion 61 and the terminal portion 5 is provided with the protrusion 61. On the other hand, a protruding portion 51 to be wrapped is formed, and on the other hand, a hole 21 is provided in the panel 2 at a position corresponding to the protruding portion 51, and the protruding portion 51 is inserted into the hole 21 and positioned, and the terminal portion 5 is placed at an appropriate position. The panel 2 has a mounting structure in which it is screwed and fixed.

[Operation / Effect] In the mounting structure of the present invention, the terminal portion 5 can be easily and accurately positioned on the body or door panel 2 by the protruding portion 51, and the terminal portion 5 is positioned by the protruding portion 51 and then screwed. Since the whole part 5 does not rotate and only one screw tightening point is required, it is possible to avoid the sealing line and select an appropriate position. Further, since the protrusion 61 of the reinforcing insert 6 is embedded in the protrusion 51, the protrusion 51 is not deformed or damaged by the rotation torque when the screw is tightened.

[Embodiment] In the first embodiment shown in FIGS. 1 to 3, the hollow weather strip 4 extruded from sponge rubber has a hollow end formed with a molding end portion formed along the body panel surface. 5 is a connection shape. A reinforcing insert 6 made of sheet metal is embedded in the terminal portion 5. The insert 6 has a protrusion 61 formed in a cut-and-raised shape. The protrusion 61 further protrudes from the mounting surface of the terminal portion 5, and the terminal portion 5 is formed with a protruding portion 51 so as to include the protrusion 61. A screw hole is formed in the reinforcing insert 6 at a screw fastening portion to the body panel 2.

Molding of the terminal portion 5 is performed by setting the terminal of the weather strip 4 and the reinforcing insert 6 in the cavity of the mold, and injecting a solid rubber material so as to wrap the insert 6 in the cavity.

The roof side 1 (FIG. 8) is used to mount the weather strip 4 having the thus-formed end portion 5 on an automobile.
The weather strip 4 is fitted into the retainer provided along the line. Then, as shown in FIG. 3, the projecting portion 51 is pushed into the hole 21 formed in the body panel 2 in correspondence with the projecting portion 51 of the terminal portion 5 to position the terminal portion 5, and then as shown in FIG. Then, fix it to the body panel 2 with screws 7 and fix it.

In the above, the diameter of the hole 21 formed in the body panel 2 is formed slightly smaller than the outer diameter of the protruding portion 51.

When the protrusion 51 is pushed in, the protrusion 51 made of solid rubber is elastically deformed and is easily pushed in.
Since it is restored by its own rubber elasticity and surely contacts the peripheral edge of the hole 21, its positioning becomes accurate.

In addition, if the shape of the protruding portion 51 is such that the diameter is increased on the distal end side so that the protruding portion 51 can be prevented from coming off, the diameter of the hole 21 can be made equal to the outer diameter of the protruding portion 51 at the inserted portion. You may set the same as. Although the solid rubber is shown in this embodiment, the protrusion 51 may be made of sponge rubber.

4 to 7 show a second embodiment in which the present invention is applied to another weather strip.

As shown in FIG. 4, the door sash 31 of the rear door 3 of the automobile is
A hollow weather strip 4A that seals between the upper part of the front edge of the front door and the upper part of the rear edge of the door sash of the front door and covers the center pillar is attached. As shown in FIG. 5, at the upper end of the weather strip 4A, a molded end portion 5A having a flat plate mounting portion in which the reinforcing insert 6 is embedded is formed. Then, as shown in FIG. 6, similarly to the first embodiment, the reinforcing insert 6 is formed with the protrusion 61, and the terminal portion 5A is formed with the protruding portion 51 including the protrusion 61. The terminal 51 positions the terminal portion 5A by pushing it into a hole 33 provided in a door panel 32 on the inner side of the upper corner of the door sash 31. Then, as shown in FIG. 7, the terminal portion 5A is located at a position different from the positioning portion and the door panel 32
It is tightened with a bolt 8a and a nut 8b. 9 is a washer.

Therefore, according to the mounting structure of the present invention, the workability of mounting the end portion of the weather strip is greatly improved. Also, a stable mounting state can be realized by tightening the screw at one place. Further, since the number of screw tightening points can be reduced, the appearance of the mounting portion is good, and the screw member does not impair the sealing performance.
