Abstract

PURPOSE:To facilitate positioning for a body and a door panel and provide a secured assembling condition by forming a projection at a reinforcing insert buried in a terminal and a projecting part which covers the projection in the terminal, and forming a hole at a position for the projecting part in a panel. CONSTITUTION:A terminal of a hollow weather strip 4 made by pressing out and molding sponge rubber is made into the shape fitting to the body panel surface. A molded terminal 5 is connected with it. A reinforcing insert 6 of plating is buried in the terminal 5, whereas the insert 6 is formed with a projection 61 in the raising condition. Also the terminal 5 is formed with a projecting part 51 to cover a projection 61. For assembling the weather strip 4 into an automobile, the weather strip 4 is fit into a retainer installed along a roof side. The projecting part 51 is pressed into a hole 21 formed in the body panel 2 in advance for the projecting part 51 of the terminal 5 for positioning of the terminal 5, and the weather strip is fixed at the body panel 2 by tightening with a set screw 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for attaching the end of a weather strip that is attached to a door opening of an automobile body or along the outer periphery of the door.

[Prior Art] This type of weatherstrip is generally an extrusion-molded body with a hollow seal part, and a molded end part shaped to follow the body panel surface or door panel surface is connected to the end of the extrusion molded body. It is screwed and fixed to the above panel using screws or the like (Japanese Utility Model Publication No. 6142321).

For example, in the hardtop type automobile shown in FIG. 8, a hollow weather strip is attached to the roof side 1 along the roof side 1 to seal the outer periphery of the door glass. At the end of the weatherstrip, for example at the rear end A, as shown in FIG.
The terminal portion 5 is formed by molding. A plate-shaped reinforcing insert 6 is embedded in this terminal portion 5 . and the ninth
As shown in the drawings and FIG. 10, the terminal portions are fixed to the body panel 2 with screws 7 via inserts 6 at a plurality of locations.

In this case, it takes time to accurately position the terminal portion 5 and tighten screws at multiple locations, resulting in poor workability. Further, the screw tightening point must be located at a location that avoids the seal line S with the mating member in contact with the terminal portion 5, in this example, the peripheral edge of the door glass. Therefore, the locations where screws can be tightened are restricted. Therefore, it may be possible to tighten the screw in only one place, but
At one location, the edge of the end portion 5 may be raised, and the entire end portion 5 may be rotated and deformed when tightening the screws, resulting in poor sealing performance, or it may take time to correct the deformation of the end portion 5. It took.

[Problems to be Solved by the Present Invention] Therefore, the present invention provides easy positioning of a body or door panel, a stable mounting state by tightening a screw in one place, and a terminal portion when tightening a screw. An object of the present invention is to provide a weather strip terminal mounting structure that does not cause rotation and has good mounting workability.

[Means for Solving the Problems] As illustrated in FIGS. 1 to 3, the present invention provides a reinforcing insert 6 embedded in the terminal portion 5 with a protrusion 61 and a protrusion 61 on the terminal portion 5. On the other hand, a hole 21 is provided in the panel 2 at a position corresponding to the protrusion 51, and with the protrusion 51 inserted into the hole 21 and positioned, the end portion 5 is inserted at an appropriate location. The mounting structure is such that it is fixed to panel 2 with screws.

[Operations and Effects] 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,
In addition, since the screws are tightened after positioning using the protruding portion 51, the entire terminal portion 5 does not rotate, and the screws only need to be tightened at one location, so an appropriate location can be selected while avoiding the seal line. . Furthermore, since the protrusion 61 of the reinforcing insert 6 is embedded in the protrusion 51, the protrusion 51 will not be deformed or damaged by rotational torque during screw tightening.

Embodiment In the first embodiment shown in FIGS. 1 to 3, the hollow weather strip 4 made of extruded sponge rubber has a molded terminal portion 5 shaped to follow the body panel surface. The connection is formed.

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-out shape. This protrusion 61 protrudes further than the mounting surface of the terminal part 5, and the protrusion 61 is arranged so that the protrusion 61 is included in the terminal part 5.
1 is formed. Note that the reinforcing insert 6 has screw holes formed at locations where screws are tightened to the body panel 2.

The end portion 5 is molded by setting the end of the weatherstrip 4 and the reinforcing insert 6 in a cavity of a mold, and injecting a solid rubber material into the cavity so as to surround the insert 6.

In order to attach the weather strip 4 having the terminal portion 5 formed in this way to an automobile, the roof side 1 (see FIG. 8) is used.
The weather strip 4 is fitted into a retainer provided along the . Then, as shown in FIG. 3, the protruding part 51 is pushed into the hole 21 previously formed in the body panel 2 corresponding to the protruding part 51 of the terminal part 5 to position the terminal part 5, and then the terminal part 5 is positioned as shown in FIG. Tighten and fix to the body panel 2 with screws 7 as shown.

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

When the protruding part 51 is pushed in, the protruding part 51 made of solid rubber is elastically deformed and easily pushed in, and then restored by its own rubber elasticity to form the hole 21.
Since it makes sure contact with the periphery of the blade, its positioning is accurate.

Note that if the shape of the protrusion 51 is made to have a larger diameter on the tip side to prevent it from being pulled out, as shown in FIG. 6, the hole 21
The diameter of the protrusion 51 may be set to be the same as the outer diameter of the protrusion 51 at the insertion site. Furthermore, although in this embodiment the protrusion 51 is made of solid rubber, it 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 3 of the rear door 3 of an automobile
A hollow weather strip 4A is attached to the upper part of the front edge of the front door 1, which seals the gap with the upper part of the rear edge of the door sash of the front door and covers the center pillar. As shown in FIG. 5, a molded end portion 5A having a flat mounting portion with a reinforcing insert 6 embedded therein is formed at the upper end of the weather lip 4A. As shown in FIG. 6, similarly to the first embodiment, a protrusion 61 is formed on the reinforcing insert 6, and a protrusion 51 containing the protrusion 61 is formed on the terminal portion 5A. 51 is the door panel 32 on the inner side of the upper end corner of the door sash 31
The terminal portion 5A is positioned by pushing it into the six 33 provided in the. Then, as shown in FIG. 7, the end portion 5A is screwed to the door panel 32 at a position other than the positioning position using a bolt 8a and a nut 8b. 9 is a washer.

According to the mounting structure of the present invention, the workability of mounting the end portion of the weatherstrip is greatly improved.

In addition, a stable installation can be achieved by tightening a single screw.

In addition, the number of screw tightening points can be reduced, so the appearance of the mounting portion is good, and the screw member does not impair sealing performance.
