[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an end cap for a door molding, and more particularly, to an end cap for a door molding, which is capable of restricting trapping of a lip piece for sealing a door molding when a door glass is lowered.

[0002]

[Prior Art]

 As shown in FIG. 4, there is a door glass G of an automobile of a type in which a roller (not shown) rolls in a sash guide 30 to guide its up-and-down movement. This roller is attached to the door glass side and is usually fixed by screw means called a joint pin 8. Therefore, the head of the joint pin 8 was exposed at a position near the end of the outer surface of the door glass G.

On the other hand, a door molding M is generally attached to the upper edge of the door panel P mainly for the purpose of decoration. The door molding M is made by bending a thin stainless plate, and as shown in FIG. 5 and the like, its surface is covered with a soft resin. Of this coating, a lip piece 32 having a good flexibility is projected at a portion provided on the insertion base portion 31 inserted into the gap between the door panel P and the door glass G so that the lip piece 32 is slidably contacted with the door glass G. I am doing it. Therefore, the lip piece 32 also comes into sliding contact with the above-mentioned joint pin 8 while the door glass G moves up and down.

[0004]

[Problems to be solved by the device]

 By the way, in order to smoothly move the door glass G up and down, the contact posture of the lip piece 32 with respect to the door glass G should be changed as much as possible when the door glass G is moved up and down. I won't. However, at the portion of the lip piece 32 that comes into contact with the joint pin 8, especially when lowering the door glass G, the tip of the lip piece 32 is pushed down by the head of the joint pin 8 and is wound downward. Was sometimes. In this case, the contact resistance against the door glass G becomes large, and the door glass G cannot be moved up and down in a normal state.

Therefore, the following measures have been considered in order to prevent the lip piece 32 from being caught. The first countermeasure example shown in FIGS. 5 and 6 is to push up a predetermined range (the relevant portion) of the lip piece 32 located in a portion where the ascending / descending trajectory of the joint pin 8 passes, and to partially push it up between the joint pin 8 and the joint pin 8. It is designed to have clearance. As a concrete structure, a lifting portion 33 is provided on the back side of the relevant portion of the lip piece 32. The lifting portion 33 can be formed by forming (roll forming) the lip piece 32 and then partially performing injection molding.

However, in the first countermeasure example described above, it is actually difficult to partially lift the lip piece 32, and thus it cannot be an appropriate countermeasure. The reason is that it is desirable that the lip piece 32 and the lifting portion 33 are made of the same material in terms of the connection with the lip piece 32, but the lip piece 32 is required to have good flexibility, and thus the original Since the rigidity is low, even if the lifting portion 33 is formed of the same material, it cannot fully stand up to the tip side of the lip piece 32.

Further, the second countermeasure example shown in FIG. 7 is intended to make the rising angle at the relevant portion of the lip piece 32 larger than before by setting at the time of molding. That is, by setting the base portion of the lip piece 32 at the relevant portion to be thinner than before, in detail, a thinned portion 35 is formed by removing the front side of the relevant portion more than usual to form a thin portion. By doing so, the degree of heat shrinkage after molding on the front side of the lip piece 32 becomes larger than that on the back side, and the portion of the lip piece 32 is gradually raised during the cooling period.

However, it has been found that, in reality, the lip piece 32 after molding is likely to fall due to a decrease in the rigidity of the root portion, which may, on the contrary, promote the entanglement. As mentioned above, neither case could be an effective countermeasure.

By the way, the end portion of the door molding M (the end portion on the opening side of the door) has an opening surface as shown in FIG. 6, but as it is, it is exposed to the outside when the door is opened and looks beautiful. In addition to damage, the metal end surface is easily exposed and the safety is poor. Therefore, the opening surface is normally closed by a resin end cap 34.

In view of the fact that the end portion of the lip piece is relatively close to the mounting position of the lip piece, the present invention adds a new lip piece roll-in prevention function to the end cap in addition to the original closing function. It is a thing.

[0011]

[Means for Solving the Problems]

 The structure of the present invention made with such an intention is arranged along the upper edge of the automobile door panel, and a flexibly deformable lip piece is formed upright along the width direction on the surface facing the door glass. An end cap for closing the end opening surface of the door molding, which is formed by a cover piece for closing the end portion of the door molding, and a molding insert extending from the cover piece so as to be insertable into the interior of the door molding. A predetermined range of the lip piece, which is located at a portion through which the ascending and descending loci of the projection and the projection placed at a position near the end of the door glass that is projected upward from the molding insertion piece and can be moved up and down It has a lip lifting piece for forcibly deforming.

[0012]

[Action]

 According to the above configuration, the cover piece closes the opening by inserting the molding insertion piece through the opening at the end of the door molding. At the same time, the lip lifting piece pushes up the part of the lip piece of the door molding that comes into contact with the protrusions while moving up and down the door glass, so that the part of the lip piece is forced to stand up to the tip. This allows a clearance to be retained between the tip of the lip piece and the protrusion.

[0013]

[Effect of the device]

 The effects of the present invention are as follows. Since it is possible to prevent the lip piece from being caught by the protrusion during the raising and lowering of the door glass, the door glass can be smoothly raised and lowered. This effect can also be achieved by forming a slight lip lifting piece on the existing end cap. Therefore, the structure is simple and the manufacturing cost can be suppressed. Furthermore, the work efficiency is high because all you have to do is insert the end cap.

【Example】

 Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. FIG. 2 shows a portion of the automobile door molding M that is closer to the center pillar (not shown). As in the conventional case, the door molding M has a configuration in which a thin plate made of stainless steel is used as a core material 1 and a coating 2 made of a soft resin is applied to the surface thereof. The outer edge (left side in FIG. 1) of the door molding M has a flange edge 3 folded back along the width direction, and the edge on the side facing the door glass G (right side in FIG. 1) is a door panel P. An insertion base portion 4 which is inserted into a gap between the door glass G and the door glass G is bent and formed substantially vertically. As shown in FIG. 2, the end portion of the insertion base portion 4 has a first relief portion 5 cut out over a predetermined range in order to avoid interference with the sash guide described above. In the example, the second relief portion 7 for avoiding interference with the lip lifting piece 15 described later is formed continuously in a stepwise manner. However, the door molding M is arranged such that the second relief portion 7 crosses the ascending / descending trajectory of the joint pin 8.

On the flange edge 3 side, the coating 2 applied to the door molding M projects along the width direction as a lower bending piece 9 that is tightly adhered to the upper surface of the door panel P, and at the base of the insertion base 4, the upper bending piece. Reference numeral 10 projects over the width direction. Furthermore, the coating 2 applied to the insertion base 4 extends from the central portion as a lip piece 11 toward the door glass G side and in a tongue shape. As shown in FIG. 2, the range in which the lip pieces 11 are provided extends over almost the entire width range, leaving a part near the ends. Further, this lip piece 11 has a thin hinge portion 12 at the base portion, which provides good flexibility, and while the door glass G moves up and down, its tip is the surface of the door glass G. Smoothly slides on.

The door molding M configured as described above is fixed to the door panel P by a plurality of clips, and since this fixing structure is known, it is not shown in detail.

Next, the end cap EC will be described. The end cap EC is integrally molded of a synthetic resin material, and covers the cover piece 13 that closes the open end of the door molding M, the molding insertion piece 14 that is inserted inside the door molding M, and the lip piece 11 that is lifted. And a lip lifting piece 15 for holding.

As shown in FIG. 3 and the like, the cover piece 13 has one side edge formed in conformity with the side surface shape of the door molding M, and is formed larger than the opening surface as a whole so that the opening surface of the door molding M can be closed. Has been done. A back plate 16 is bent inward from the other side edge of the cover piece 13 at a substantially right angle.

The molding insertion piece 14 is composed of an inclined portion 14a and a rising portion 14b, and is formed in a sectional shape so that it can be fitted inside the door molding M as a whole as shown in FIG. 1 or 3. The tip of the inclined portion 14a can be inserted into the inside of the flange edge 3 of the door molding M, and a projection 14c is formed at the tip, so that a slight gap is formed between the upper surface of the inclined portion 14a and the inner surface of the door molding M. It is held. This serves to reduce the contact resistance between the two when the end cap EC is inserted. The upright portion 14b is adapted to the inner surface of the insertion base portion 4 of the door molding M, and is connected to the back plate 16 and the connecting piece 17 at a position near the cover piece 13 (see FIG. 3). As shown in the figure, the connecting piece 17 extends so as to go under the lower end of the insertion base portion 4 in the first escape portion 5. Thus, the molding insertion piece 14 has such a length that it can be inserted into a position corresponding to the second relief portion 7 of the door molding M, and the lip lifting piece 15 described below is attached to the end of the joint pin 8. It is integrally provided at a position almost corresponding to the ascending / descending trajectory.

The lip lifting piece 15 is formed by bending the lower end edge of the upright portion 14 b of the molding insertion piece 14 outward and folding it back in a U-shape. The folding width ((inner groove width) is set to such an extent that it can be received with sufficient space for the insertion base 4 at the portion corresponding to the second relief portion 7, and its height is set to the lip piece. The height is set so as to push up the base portion of the lip 11. In this embodiment, as shown in Fig. 1, the inner surface of the tip of the lip lifting piece 15 has an outer surface at a position corresponding to the hinge portion 12 of the lip piece 11. In order to push up according to the shape, the pushing-up surface 18 conforming to this shape is formed.

Next, the operation and effect of this example configured as described above will be specifically described. As described above, the door molding M is attached to the upper edge of the door panel P by a plurality of clips (not shown). In the mounted state of the door molding M, the lower bending piece 9 contacts the side surface portion of the door panel P, and the lip piece 11 contacts the door glass G while traversing the ascending / descending trajectory of the joint pin 8.

When the end portion of the door molding M attached in this manner is processed, the end surface of the molding insertion piece 14 of the end cap EC is fitted to the opening surface of the door molding M, and is pushed in as it is. That is, the tip of the inclined portion 14a is fitted to the inside of the flange edge 3, and the rising portion 14b side is pushed along the insertion base portion 4. When the cover piece 13 is pressed until the cover piece 13 comes into contact with the end surface of the door molding M and the opening surface is closed, the lip lifting piece 15 has the rising portion corresponding to the second relief portion 7 of the door molding M. 14b is received inside. At this time, since the base of the lip piece 11 is directly pushed up by the push-up surface 18 of the lip lifting piece 15, the area around the pushed-up portion is forcibly deformed upright over a predetermined range (imaginary line in FIG. 1). The state indicated by is transformed to the state indicated by the solid line). As described above, since the lip lifting piece 15 is arranged at the position corresponding to the ascending / descending trajectory of the joint pin 8, the joint pin 8 passes through the upright deformed portion of the lip piece 11 as the door glass G moves up and down. Will be. Therefore, almost the entire area of the lip piece 11 is in sliding contact with the door glass G, but only the portion corresponding to the joint pin 8 avoids interference with the pin 8. Therefore, even when the door glass G is lowered, the normal standing posture can be maintained without the involvement of the lip piece 11 unlike the conventional case. Therefore, the up-and-down operation of the door glass G can always be smoothly performed.

As described above, according to the end cap EC of this embodiment, since the lip lifting piece 15 directly lifts the lip piece 11, the interference with the joint pin 8 is surely avoided. Further, since a dedicated member for lifting the lip piece 11 is not provided, but the lip lifting piece 15 is integrally formed by using the existing end cap EC, the configuration is simple. Further, no special operation for lifting the lip piece 11 is required, and the work only needs to be done by inserting the end cap EC, so that the work efficiency is excellent.

In this example, the lip piece 11 is deformed upright so that a slight clearance is held between the lip piece 11 and the joint pin 8. It is also possible to set the sliding contact. Moreover, the object that the door molding M avoids interference is not limited to the joint pin 8 and may be another protrusion existing near the end of the door glass.
