Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a mold joint structure used in automobile windows.

[Prior Art] Some automobile rear windows or side windows have a molding provided at the periphery of the window glass (wind panel). Such a molding usually consists of a molding placed on the side of the window glass and a molding joint placed on the corner of the window glass.
By combining these into a frame shape, the molding is arranged around the entire periphery of the window glass.

Incidentally, the molding joint that constitutes such a molding has conventionally been used with a structure as shown in FIG. 5. That is, this has an L-shaped claw part b protruding from the center of the back surface of a strip-shaped mold joint body a formed in an L-shape, with the locking side facing inside, and this claw part. It is constructed by integrally providing a rib c on the back part of b. When installing this mold joint, the window glass e is attached to the bottom h of the installation seat d with adhesive g, as shown in FIG. By inserting it between the end face of the window glass e and the inclined wall part f of the installation seat d facing away from it, the claw part b engages with the inner surface of the corner part of the window glass e, and
The rib c comes into elastic contact with the inclined wall portion f. Thereby, the mold joint main body a is fixed in a state covering the space between the window glass e and the wall part f.

[Problem to be solved by the invention] By the way, when installing the window glass e, it is done so that the distance between the inclined wall part f of the installation seat d and the end face i of the window glass e is approximately constant. There are variations in the dimensions of the windshield c, and of course there are also variations in the fixing position of the window glass c. These variations change the width l between the end face i of the window glass e and the inclined wall f facing away from it, but even in such a state the molding joint can be installed smoothly. It is necessary to do so.

However, in the above-mentioned conventional mold joint, if the width l between the end face i of the window glass e and the inclined wall f facing away from it varies in the direction of decreasing, the claw part b and the rib c Since they are integrated, variations cannot be absorbed, making it difficult to insert. For this reason, the workability of attaching the mold joint inevitably deteriorates, and there is a need for something that can improve this point.

[Means for Solving the Problems] This invention was made in view of the above-mentioned circumstances, and includes an installation seat having an inclined wall portion and a bottom portion formed by recessing a panel around the window opening of a vehicle in an annular shape. Ingredients,
A molding joint is fitted between an end surface of a corner portion of the window glass fixed to the bottom portion and the inclined wall portion facing the end surface of the corner portion. a molding joint body formed in a substantially L-shape similar to the above and shielding the above-mentioned gap, and a molding joint body protruding from the center of the back surface of the molding joint main body and capable of being engaged with and detached from the inner surface of the corner portion of the window glass; an elastically deformable pawl having a locking pawl that can be inserted into and removed from the mold joint; and a pair of support parts that are shaped along the sloped wall part and can come into elastic contact with the sloped wall part, and furthermore, when fitted into the gap, the claws The portion is elastically displaced toward the inclined wall portion and the pair of support portions are each elastically displaced toward the end surface of the corner portion, so that the width determined by the claw portion and the pair of support portions becomes a width in order to absorb variations in the distance. It is characterized by its narrow structure.

[Function] In the mold joint of the present invention, the claw portion and the support portion are separated, and the claw portion is elastically displaced toward the inclined wall portion and the pair of support portions are each elastically displaced toward the end face side of the corner portion. Since the width determined by the pair of support parts can be made narrower, even if the distance between the end face of the corner part of the window glass and the inclined wall part of the installation seat is smaller than the specified width, this variation can be accommodated. , a mold joint can be inserted. In addition, after the mold joint is inserted, the support part elastically contacts the inclined wall of the installation part to restrict displacement in the width direction between the sides, and the mold joint body elastically contacts the outer surface of the corner part of the panel and window glass. By holding the window glass between the back surface and the locking pawl that engages with the inner surface of the corner portion, the window glass is held within the window.

[Embodiment of the invention] This invention will be described below based on an embodiment shown in FIGS. 1 to 4. Figure 1 shows the rear side of a passenger car, where 1 is the roof panel, 1a is the rear pillar (or C-pillar), 4 is the trunk lid, and 2

on the other hand. The molding joint 3b, which is the essential part of this invention, will be explained with reference to FIGS. 2 to 4. Reference numeral 6 indicates the molding joint body. The mold joint main body 6 has a dimension larger than the width dimension l of the above-mentioned gap 12, and the entire mold joint body 6 is in the form of an L-shaped band plate that follows the shape of the corner portion 20 of the window glass 2a.

A claw portion 7 is provided protruding from the back surface of the corner portion at the center of the back surface of the mold joint main body 6.
The claw portion 7 has an arc-shaped wall portion 7a that is protruded from the center of the back surface of the mold joint body 6 and follows the curve of the mold joint body 6. The thickness of this wall portion 7a is made thin. This allows the wall portion 7a to be elastically displaced in the width direction of the gap 12. Note that the arcuate shape of the wall portion 7a follows the shape of the corner portion 20 of the window glass 2a.

As shown in FIG. 3, a substantially L-shaped locking pawl 7b with the locking side facing inside the corner portion 20 is formed at the tip of the wall portion 7a. The locking claw 7b can be inserted into and removed from the width l of the space 12, and when inserted into the space 12, the locking claw 7b can be inserted into the width dimension l of the space 12, and when inserted into the space 12, the locking claw 7b can be inserted into the width dimension l of the space 12.
It has a size that can be locked with the inner surface 22 of the end portion.

Further, reference numeral 8 denotes a pair of elastically displaceable ribs (corresponding to supporting portions) which are provided on both sides of the claw portion 7 and adjacent to the claw portion 7 on the back surface of the mold joint main body 6. These ribs 8, 8 are arranged along with the claw portion 7 in the circumferential direction of the window glass 2a. A tapered surface 8a corresponding to the shape of the inclined wall portion 5a is formed on the outer surface of the isolation portions 8, 8 on the outside in the bending direction of the mold joint main body 6. Further, the size of each rib 8, 8 is smaller than the width dimension l of the gap 12, and the rib 8 together with the claw part 7 is
2, the tapered surface 8a of the rib 8 is set so as to come into contact with the wall surface of the inclined wall portion 5a.

Due to the structure of the claw portion 7 and rib 8, the claw portion 7
The whole of the rib 8 can be bent outward in the bending direction of the mold joint main body 6 (toward the inclined wall portion 5a side), and the whole rib 8 can be bent in the opposite direction independently from this, that is, in the bending direction of the mold joint main body 6. Inside (end face 21 side of corner part 20 of window glass 2a)
This allows it to flex.

That is, in the mold joint 3b, the claw portion 7 is elastically displaced toward the inclined wall portion 5a side, and the ribs 8, 8 are each elastically displaced toward the end surface 21 side of the corner portion 20 of the window glass 2a, so that the claw portion 7 and the pair of ribs 8 are elastically displaced. , 8 can be made narrow, so that the structure is such that it is possible to absorb variations in the width dimension l of the gap 12 on the smaller side.

Therefore, when attaching the mold joint 3b in the above-described configuration, the window glass 2a is attached to the bottom 5b of the installation seat 5 with the adhesive 10, that is, the window glass 2a is attached to the rear window attachment port 11. In the state, first,
The mold joint main body 6 is arranged so as to follow the position of the gap 12 of the corner part 20 of the window glass 2a. Then, while covering with the mold joint main body 6, the claw part 7 and the ribs 8, 8 are inserted into the space between them.

Then, the rib 8 bends inward in the bending direction of the mold joint main body 6 shown by arrow A in FIG. 2, and comes into contact with the wall surface of the inclined wall portion 5a of the installation portion 5 as shown in FIG. 4. The claw portion 7 is bent outward in the bending direction of the mold joint main body 6 as shown by arrow B in FIG. 2, and finally, as shown in FIG. It engages with the inner surface 22 of the end portion of the corner portion 20. As a result, the mold joint 3b is attached to the bottom part of the corner part 20 of the window glass 2a, and the mold joint body 6 is attached to the bottom part of the corner part 20 of the window glass 2a.
