Description

[Detailed description of the invention] This invention is based on a weather strip that is installed along the lower edge of the window opening of an automobile door, and is equipped with a sealing piece that slides against the exterior surface of the window glass that moves up and down, or where the weather strip and molding are integrated. Regarding the seal attachment device that attaches the waist molding (also called belt molding, and the weather strip and waist molding are collectively referred to as a seal in this book) with an integrated clip, it is necessary to attach the seal to the window opening of the door panel. Attach an auxiliary piece along the lower edge by welding, etc., create vertical openings at appropriate intervals between the door panel and the auxiliary piece, and mold a plastic clip to hold the seal and insert it through the opening. This fixed the clip upward so that it would not come off, and the seal could be attached to the door panel via the clip.

In order to attach a seal along the lower edge of a window opening, various types of clips are conventionally known, which are formed by making cuts in a metal plate and roughly bending them, and are fixed to the vehicle body in various ways. For example, in Utility Model Publication No. 50-18257, it is fixed by covering from above the protrusion of the two inner and outer panels that overlap and protrude upward from the lower edge step of the window opening of the door panel; 51−39919
In this case, bend the door panel downward at the back of the lower edge step of the window opening, insert the lower edge step into the hole drilled in the corner of the downward facing piece, and fix it. It is fixed by inserting it into the hole drilled in the piece.

Both of them are equipped with a retaining groove that opens upward, and the seal is pushed into the groove from above to be retained.When the window glass descends, the seal is pressed against the bottom of the retaining groove, but when it rises, Sometimes they are subjected to forces that force them to come out of the grooves, and during long-term use, they may come out of the grooves. For this reason, during the above-mentioned actual operation, in 1988-39919, a downwardly pointing claw was installed on a part of the metal plate forming the holding groove, and when an upward force was applied to the seal, this claw would bite into the seal. However, during long-term use, the nails will gradually become stuck in the seal and the seal will be torn.

Furthermore, for the door panel, in the above-mentioned Utility Model Publication No. 50-18257, it was necessary to bend the two inner and outer plates to form a protrusion, and to fix both protrusions in an overlapping state.
-32816, 51-39919, and 17027-17027 require bending after punching the hole, which requires a lot of processing time. Furthermore, as mentioned above, conventional clips are made by making cuts in a metal plate and making complicated bends to form them, making manufacturing time-consuming and poor productivity.

Therefore, the present invention eliminates the process of punching or cutting out mounting holes in the door panel by fixing the auxiliary piece, which forms a vertically open opening between the door panel and the door panel, by welding, etc. is molded with plastic and has manufacturing problems,
This eliminates the risk of rusting during installation and use, and by inserting the clip penetratingly into the opening, it prevents the clip or seal from being removed when the window glass is raised to close the window during use. This has been completely prevented and will be explained below with reference to the illustrated embodiment.

Reference numeral 1 designates the outer panel of the door, and a portion slightly below the lower edge of the window opening is once horizontally bent inward to form a step 1', and an upright piece 2 is provided at the back of the step 1'. Then, on the back side of the upright piece 2, an auxiliary piece 4 is fixed by welding or the like, which faces the back side of the upright piece and forms openings 3 opening vertically therebetween at appropriate intervals along the upright piece. The auxiliary piece 4 can be formed by bending a metal band plate into a zigzag shape and fixing it in a series along the upright piece by welding or the like, or by bending and forming a plurality of metal strips to form openings individually and standing them upright. They may be fixed by welding along one side at a predetermined interval. This auxiliary piece also has the role of reinforcing the upright piece.

The clip C, molded from plastic, is generally T-shaped and has a top wall 5, a central leg 6 that extends down from the center of the top wall 5, passes through the opening 3, and projects downwardly from the bottom end of the opening. , has a seal holding device 9 consisting of a front leg 7 extending from each front and rear end of the upper wall 5 to the outside of the upright piece 2 and a rear leg 8 descending to the inside of the auxiliary piece 4, as will be described later.

The seal S here is made up of a rubber weather strip part 10 with a seal piece 10' and a molding part 11 formed by bending and molding a stainless steel plate into an inverted U shape, forming a fitting groove S' into which the clip C is inserted. In this waist molding, a weather strip part 10 having a seal piece 10' is formed on the outer surface of one leg 11a of a molding part 11 bent into an inverted U-shape by an insert molding method, At that time, a rubber protective piece 1 is attached to the lower end of the other leg 11b.
1' is coated.

Now, in the embodiment shown in FIGS. 1 and 2, the thickness of the upper half of the central leg 6 is approximately equal to the facing distance of the opening 3 between the upright piece 2 and the auxiliary piece 4, so that it fits almost snugly into the opening 3. The lower half has a thickness that decreases toward the lower end, making it easier to insert into the opening. The central leg 6 is provided from the front or rear surface for engaging the lower surface of the step 1' or the lower edge of the auxiliary piece 4 when the lower surface of the upper wall is received by the upper end of the opening 3 and cannot be pushed in any further. It has a protruding claw 12. In this example, claw 1
2 protrudes from the front surface of the central leg for engaging with the lower surface of step 1', but in order to engage with the lower edge of the auxiliary piece 4, it may protrude from the rear surface of the central leg.
The claw 12 may be thickened and protrude from the front or rear surface of the central leg, but in this embodiment, a tongue piece 12' surrounded by a U-shaped cutout is formed on the central leg 6.
The free end of this tongue piece 12' is thickened.

Moreover, the seal S is attached to both leg strips 11a, 1 of the molding part.
Inward bent portions 11a', 11 at the lower end of 1b, respectively.
b', and is adapted to be latched to the lower ends of the front leg 7 and rear leg 8 of the clip c.

Therefore, when the clip c is pushed into the fitting groove s' of the seal s from the upper wall 5, and the upper wall 5 substantially contacts the bottom of the fitting groove s', the bent portions 11a', 11b' The front legs 7 and rear legs 8 of the clip, which had been bent by the clip, pass over the bent portion and lock it from the inside, gripping the seal. After the clips c are thus attached to the seals at equal intervals to the openings 3, the lower half of the central leg 6 of each clip protruding from the seal s is pushed into the openings 3 from above.

This causes the pawl 12 to be deformed on one of the opposing surfaces of the upright piece or the auxiliary piece, and when the underside of the top wall 5 is received by the upper edges of both said pieces, the pawl 12 passes downward through the opening 3 and becomes stepped. It engages with the lower surface of 1' or the lower edge of the auxiliary piece 4 from below and is pulled by this, preventing it from coming off upward.
Also, at this time, the lower end of the leg 11b of the seal comes into contact with the step 1' via the protective piece 11'.

As a result, the clip holds the claw 12 against the door.
Furthermore, since the seal s is prevented from moving upward relative to the front and rear legs 7 and 8 of the clip at the bent portions 11a' and 11b', it cannot be pulled out even if the window glass is raised to close the window. Never.

In this embodiment, a hollow part 13 is provided from the upper wall 5 to the central leg 6 and is open at the upper end.
2' is formed to stand up in this hollow part 13 from the lower end 6' of the central leg, thereby reducing the amount of resin used.

The thickness of the central leg 6 of the clip c in the embodiment shown in FIGS. will provide sufficient space. For this purpose, the central leg integrally has a tension piece 14 at the lower rear surface of which the tip contacts the inner surface of the auxiliary piece 4. The central leg then has a bent elbow 15 at its lower end for engaging the underside of the step 1'. Of course, the central leg can also be in contact with the inner surface of the auxiliary piece 4 on the rear side, in which case the tension piece 14 will come into contact with the back side of the upright piece, and the elbow 15 will engage with the lower edge of the auxiliary piece 4. Provided as follows. An upright piece 16 is folded up from the lower end of the rear leg 8 to form a seal holding groove 16' between it and the rear surface of the rear leg, and the upper end of the upright piece 16 is pushed into the seal holding groove from above. It has a check piece 17 that locks the part of the sealed seal so that it cannot be pulled back. As in the previous embodiment, the lower end of the front leg 7 engages the bent portion 11b' at the lower end of the leg strip of the molding portion of the seal.

The difference between the seal s and the previous embodiment is the leg strip 11.
The lower end portion attached to the outer surface of a has a protrusion 18 that engages with the check piece 17 when pushed into the seal holding groove 16' from above.

Therefore, the protrusion 18 of the seal is inserted into the seal retaining groove 1.
6', push the clip c from the upper wall 5 into the fitting groove s' of the seal, and remove the check piece 17 and the protrusion 1.
8 and the lower end of the front leg 7 and the bent portion 11b' of the lower end of the leg 11b, the clips are attached to the seal at intervals equal to the interval of the openings 3. Then, the central leg 6 of each clip is inserted diagonally into the opening 3 as shown by the chain line in FIG. 4, and pushed in while mainly bending the tension piece 14. This allows the upper wall 5 to open 3
When the elbow 15 is received by the upper surface, it passes downward through the opening and engages the lower surface of step 1' from below, and at the same time, the tension piece 14 returns straight to move the elbow 15 to step 1'.
Pressing against the lower surface, the front leg 7 brings the lower end of the leg strip 11b of the seal into contact with the step 1' via the protective piece 1b'.

The tension piece 14 thus keeps pressing the elbow 15 against the underside of the step 1', so that the clip does not wobble in the opening, and the elbow 15 is pushed upward by the upward force applied when the window glass is raised. Since almost no force acts on the strut 14, the elbow remains suspended on the underside of the step, and the clip does not come off upwards, nor does the seal held thereon in a non-returning manner.

The clip c of the embodiment of FIG. 5 is substantially similar to the clip of the embodiment of FIGS. A tension piece 14 is provided at the lower front of the leg, and the tip of the extension piece 14 is directed toward the bottom of the back of the upright piece.
5 so that the seal can be installed in the door panel by pushing it into the opening formed by the upright piece and the auxiliary piece, other things being almost the same.

As is clear from the above, in the present invention, the lower edge of the window opening of the door panel only needs to be bent at the step 1' and the upright piece 2. Instead, an auxiliary piece 4 must be fixed to the back of the upright piece by welding or the like to form the opening 3, but the auxiliary piece 4 uses a mold that is much smaller than that used to process the door panel, and has a high height. It can be manufactured efficiently, and welding can be done by automatically positioning and welding using spot welding, etc., so the manufacturing cost is lower than manufacturing a mold to create a hole for attaching a clip in the door panel, and then bending it after opening the hole. becomes cheaper.

The clips can be mass-produced by plastic injection molding, and do not damage the interior and exterior surfaces of the door panel or the auxiliary pieces during and after installation, completely preventing rust. In addition, the clip is engaged to prevent the seal from coming off upwards, and the clip itself is also fixed to the door so that it does not come off upwards, so even after long-term use, the area around the seal will not come off when the window glass rises. There isn't. In addition, in the present invention, the auxiliary piece, which is fixed by welding or the like to the back of the upright piece to form the opening, does not require any hole drilling, so it is easy to manufacture.

Incidentally, in each of the embodiments, the seal is attached by attaching a clip to the seal s and then attaching it to the vehicle body using the clip, but in contrast to this, the seal is first attached to the vehicle body by attaching the clip to the vehicle body. The seal can then be attached over the clip.
