Description

[Detailed description of the invention] This invention is a weather strip equipped with a sealing piece that slides against the exterior surface of the window glass that moves up and down, or a weather strip and a molding along the lower edge of the window opening of the car door. Form the lower edge of the window opening in order to attach the integral waist molding (also called belt molding; the weather strip and waist molding are collectively referred to as a seal in this document). An upright piece of a door panel, both sides of this upright piece and an auxiliary piece fixed to the back of the upright piece by welding, or an auxiliary piece fixed to the back of the upright piece by welding etc. and protruding higher than the upright piece. The present invention relates to an improvement in a plastic clip for attaching a seal by clamping and fixing it to an upright edge of an upwardly protruding part.

A clip for attaching a seal by pressing it over the upwardly facing metal plate forming the lower edge of the window opening and fixing it under pressure in this manner is known, for example, from Japanese Utility Model Publication No. 18257/1983. However, this clip requires complicated bending of the metal plate, which is time-consuming, and when the window glass is raised, the seal piece that is in sliding contact with the glass receives an upward force, which causes the clip to bend. In order to prevent the clip from slipping upward from the upright edge of the panel, the clip is made to have a claw that is protruded diagonally upward and hooked onto the painted outer surface of the panel. For this reason, the nails peel off the paint film on the outside surface of the panel, and over a long period of time, rust develops from the peeled part of the paint film, and the rust flows out along with water onto the outside surface of the panel, damaging the appearance. Additionally, this clip cannot effectively prevent the installed seal from wobbling when subjected to force from outside the car toward the inside of the car, and when that force is strong, the seal may come off with the clip, or the seal may come off from the clip. It ends up.

Therefore, this invention eliminates manufacturing problems and the risk of damaging the panel and causing rust during installation and use by molding the clip with plastic, and at the same time allows the seal to be installed without wobbling. It has been improved.

Hereinafter, the present invention will be explained with reference to an embodiment shown in the drawings. Reference numeral 1 is an outer panel of a door, and a portion slightly below the lower edge of the window opening is bent horizontally to form a step 1'. A low upright piece 2 is provided at the back of the holder. On the back side of the upright piece, an auxiliary piece 3 that also serves as reinforcement and protrudes higher than the upper end of the upright piece is fixed by welding or the like, and in this embodiment, the upper end of the auxiliary piece that protrudes above the upright piece attaches a clip. It has a raised edge 4.

However, as mentioned above, the upright edge 4 may be the upright piece 2 when the auxiliary piece 3 is not attached in this figure,
Furthermore, as shown in the conventional example of Japanese Utility Model Publication No. 50-18257, an auxiliary reinforcing piece is welded to the back of the upright piece 2 with its upper end aligned with the upright piece, and the upright piece and the upright piece are It may also be formed by the upper end of the auxiliary piece for lining.

In any case, mounting holes 5 are provided in the upright edge 4 at appropriate intervals along the lower edge of the window opening. The clip C is injection molded from plastic into a roughly R-shape and has a support piece 7 folded back at an upper end 6 and a clamping piece 8.
The clamping piece 8 faces the support piece 7 at the upper part with a narrow interval that is less than the thickness of the upright edge 4, but the gap is smaller than the upright edge 4. The spacing may be approximately the same as the plate thickness of No. 4. The lower half forms an arm 9 bent diagonally outward. Further, the arms 9 may extend from both sides of the clamping piece. Then, there is a claw 10 that projects into the mounting hole 5 from one of the opposing surfaces of the support piece 7 and the clamping piece 8, in this case from the center of the support piece 7. Of course, the claws 10 may protrude from the surface of the pinching piece 8 facing the support piece 7.

Seal S shows a waist molding in which a rubber weather strip part 11 with a seal piece 11' is integrated with a molding part 12 formed by bending and molding a stainless steel plate into an approximate shape. appears to straddle clip C. The weather strip portion 11 is molded on the outer surface of one of the leg strips 12a of the molding portion by insert molding, and at the same time, a protective piece 12' that wraps the inwardly curved lower end of the other leg strip 12b is also molded. Adhesive molding.

Furthermore, the clip has an integral upright piece 13 that is folded upward from the lower end of the support piece 7, and teeth 14 that bite into the weather strip portion are provided on opposing surfaces of the upright piece 13 and the support piece 7. be. Furthermore, a corner 15 projects horizontally or diagonally upward from the upper end 6. As shown in FIG. 2, the aforementioned arm 9 is suspended from the inside on the inwardly bent lower end 12b' of the leg 12b of the seal, and the corner 15 is attached to the upper end corner of the leg 12b inwardly. I support it from the beginning.

To install the seal, push the weather strip portion of the seal S into the space between the upright piece 13 and the support piece 7 while pushing the clip into the grooved interior S' of the seal. In this embodiment, it has been explained that the upright piece 13 and the support piece 7 are fitted by being pushed into the space between them.
What is required in the present invention is a structure that can perform the function of preventing the seal from slipping out. Therefore, at least one of the support piece and the side of the seal may be provided with means for preventing the seal from coming off. As a result, the corner 15 is deflected and passes upwardly over the lower end of the leg strip 12b, and then the arm 9 is deflected and passes over the lower end of the leg strip 12b.
When passing over the lower end of the weather strip, the lower end of the weather strip reaches the folded end of the upright piece and the support piece, the corner touches the upper corner of the leg 12b, and the arm 9 reaches the corner of the upper end of the leg 12b.
The inwardly facing lower ends of 2b are each supported from the inside. After a plurality of clips are attached to the seal at intervals of the attachment holes 5 in this manner, the upper end of the upright edge 4 is aligned between the support piece 7 and the pressure piece 18 and pushed in from above. As a result, the opposing parts of the support piece and the pinching piece slide down while pressing the upright edge 4 until the upper end 6 is received by the upper end of the upright edge 4, and at the point when it can no longer be pushed in. The claw 10 engages in the mounting hole 5,
The rubber protective piece 12' attached to the lower end of the leg strip 12b of the seal is compressed and brought into contact with the step 1' of the door panel.

In this state, the weather strip section 11 has teeth 1.
4 bits in, and since the lower end of the leg 12b' is supported by the arm 9 from the inside, when the window glass G rises, the seal S, which is in sliding contact with the outer surface of the window glass G with the seal piece 11', faces upward. The seal does not come off the clip even when subjected to force, and the clip itself has a claw of 10
is caught on the upper edge of the mounting hole 5, so it does not come off from the door panel. In addition, since the arm 9 is bent outward, it serves as a guide to guide the upper end of the upright edge 4 to the opposing interval between the support piece and the pressure piece when the seal is pushed into the vehicle body from above using a clip. Improve work efficiency.

The corner 15 prevents the seal S from shaking when it receives a force from outside the vehicle toward the inside of the vehicle, and also prevents the claw 10 of the clip from coming off the mounting hole 5 due to the force.

Since the upright edge 4 is formed of the auxiliary piece 3, the spacing between the supporting piece 7 and the pressing piece 8 is preferably set to be equal to or less than the thickness of the auxiliary piece 3; If formed, it is less than an upright piece, and
If it is formed of an upright piece and an auxiliary piece, the total thickness is less than or equal to the total thickness thereof, but it may also be approximately the same as the thickness of the upright edge as described above. In this embodiment, the claw 10 is provided on the support piece 7 downwardly away from the opposing portion of the support piece and the pinching piece that sandwich the upright edge 4, and the lower half of the pinching piece is attached to the leg strip 12b of the seal. The clip is very easy to form because it has an obliquely outwardly inclined arm 9 which deviates from the claw 10 to engage the bent portion 12b' at the lower end of the clip.

As is clear from the above, since the clip of the present invention is molded from plastic, it can be mass-produced, and since it does not damage the door panel during installation or use, it prevents rust and allows the window to be closed during use. Therefore, even if the glass moves upward, the seal will not come off and it will not come off the vehicle body.

Moreover, the seal can be installed without wobbling.

The weather strip portion 11 may be provided with teeth corresponding to the teeth 14 so that the teeth mesh with each other when attached to the clip. Also, when installing the seal, we have described the case where the clip is attached to the seal first, and then the seal is attached to the car body, but it is also possible to attach the seal to the car body first, and then cover the seal with the seal. can.
