[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an end cap for a door molding, and more particularly to a door molding end cap capable of restricting a sealing lip of a door molding from being caught when a door glass is lowered.

[0002]

2. Description of the Related Art As shown in FIG. 4, there is a door glass G of a type in which a roller (not shown) in a sash guide 30 is rolled to guide the ascending / descending operation as shown in FIG. is there. This roller is mounted on the door glass side, and is usually fixed by a screw means usually called a joint pin 8. Therefore, the head of the joint pin 8 is exposed at a position near the end of the door glass G on the outer side of the vehicle.

On the other hand, a door molding M mainly for decoration is generally mounted on the upper edge of the door panel P. The door molding M is formed by bending a thin stainless steel plate, and has a surface made of a soft resin as shown in FIG. 5 and the like. Of this coating,
A lip piece 32 having good flexibility protrudes from a portion provided on the insertion base 31 inserted into a gap between the door panel P and the door glass G so as to slide on the door glass G. Therefore, the lip piece 32 is connected to the joint pin 8 while the door glass G moves up and down.
Will also come into sliding contact with.

[0004]

By the way, in order to smoothly raise and lower the door glass G, the contact posture of the lip piece 32 with the door glass G changes as much as possible when the door glass G is raised and lowered and when the door glass G is lowered. You have to keep it. However, the lip piece 32
In the portion that comes into contact with the joint pin 8 at the time, especially when the door glass G is lowered, the lip piece 32
Of the joint pin 8 was pushed down by the head of the joint pin 8 and was sometimes entangled downward. In this case, a large contact resistance with respect to the door glass G occurs, and the door glass G cannot be moved up and down in a normal state.

In order to prevent the lip piece 32 from getting caught, the following countermeasures have been considered. The first countermeasure example shown in FIG. 5 and FIG. 6 is that the lip piece 32 located at the portion where the lifting trajectory of the joint pin 8 passes is pushed up by a predetermined range (the relevant portion) to partially clear the clearance between the lip piece 32 and the joint pin 8. Is to be held. As a specific configuration, a lifting portion 33 is provided on the back side of the 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 cannot be an appropriate countermeasure. The reason is that the lip piece 32
It is desirable that the lip piece 32 and the lifting portion 33 be made of the same material in view of the joining with the lip piece 32. However, the lip piece 32 needs to have good flexibility and is inherently low in rigidity. This is because even if the lifting portion 33 is formed of a material, it cannot be sufficiently raised up to the tip side of the lip piece 32.

[0007] The second countermeasure example shown in FIG. 7 is intended to increase the rising angle of the lip piece 32 at the corresponding portion in advance by setting at the time of molding. In other words, by setting the base portion of the portion of the lip piece 32 to be thinner than before, in detail, a thinned portion 35 in which the front side of the portion is thinned more than usual to form a thinner portion is set. By doing so, the degree of heat shrinkage on the front side of the lip piece 32 after molding is greater than that on the back side, and the lip piece 32 is gradually raised during the cooling period.

However, in practice, the molded lip piece 32 tends to fall due to a decrease in the rigidity of the base portion,
On the contrary, it was found that the result might be that the entrainment was promoted. As described above, neither case could be an effective countermeasure.

By the way, the end of the door molding M (the end on the opening side of the door) has an open surface as shown in FIG. 6, but if exposed as it is, the door is exposed to the outside when the door is opened, and the appearance is impaired. At the same time, the metal end face is easily exposed and lacks safety. Therefore, the opening surface is usually closed by an end cap 34 made of resin.

In the present invention, in consideration of the relative position of the lip piece and the end cap being relatively close to each other, in addition to the original closing function, the lip piece is additionally provided with a function to prevent the lip piece from being caught in the end cap. Things.

[0011]

SUMMARY OF THE INVENTION With the above in mind, a configuration of the present invention made with this in mind is formed so that an end opening surface of a door molding disposed along an upper edge of an automobile door panel can be closed, A door molding end cap in which a lip piece that can be bent and deformed in close contact with the door glass is formed upright along the width direction on a surface facing the door glass, and a cover piece that closes an end of the door molding. A molding insertion piece extending from the cover piece so as to be inserted into the interior of the door molding, and a lip lifting piece formed upward and folded back from the molding insertion piece in a U-shape. The lifting piece pushes up and supports a portion of the lip piece corresponding to an area where a protrusion disposed near the end of the door glass passes as the door glass moves up and down. And in, it is characterized in that the interference is forced deformably formed in a direction which is avoided with the projections.

[0012]

According to the above construction, 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 portion of the lip piece of the door molding that comes into contact with the protrusion during the ascent and descent of the door glass from below, so that the lip piece is forcibly erected up to its tip. This makes it possible to maintain a clearance between the tip of the lip piece and the projection.

[0013]

[Effects of the Invention] The effects of the present invention are as follows. Since a situation in which the lip is caught by the projections during the raising and lowering of the door glass is avoided, the door glass can be raised and lowered smoothly. This effect can also be achieved by forming a slight lip lifting piece on the existing end cap. Therefore, the configuration is simple and the manufacturing cost can be suppressed. Furthermore, the work efficiency is high because the work of merely inserting the end cap is sufficient.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. 2 is a door molding M for an automobile.
2 shows a portion closer to a center pillar (not shown). The door molding M has a structure in which a thin plate made of stainless steel is used as a core material 1 and a surface 2 made of a soft resin is applied to the surface of the core material 1 as in the related art. The edge of the door molding M on the vehicle outside (the left side in FIG. 1) extends along the width direction along the flange edge 3.
Is folded back and the side facing the door glass G (FIG. 1)
An insertion base 4 inserted into the gap between the door panel P and the door glass G is bent substantially in the vertical direction. As shown in FIG. 2, the end of the insertion base 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 this embodiment, a second relief portion 7 for avoiding interference with a lip lifting piece 15 described later is formed continuously in a stepwise manner. However, the door molding M is arranged so that the second relief portion 7 crosses the elevating locus of the joint pin 8.

The coating 2 applied to the door molding M is provided on the flange edge 3 side with a lower bending piece 9 which is in close contact with the upper surface of the door panel P.
The base portion of the insertion base 4 protrudes along the width direction as the upper flexible piece 10. 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 and in a tongue shape. As shown in FIG. 2, the range in which the lip pieces 11 are provided extends over substantially the entire width range except for a part near the end. Further, the lip piece 11 has a thin hinge portion 12 at a base portion, whereby good flexibility is obtained, and the tip of the lip piece 11 is attached to the surface of the door glass G while the door glass G moves up and down. Make smooth sliding contact.

The door molding M constructed as described above is fixed to the door panel P by a plurality of clips, and since this fixing structure is publicly known,
Details are not shown.

Next, the end cap EC will be described. The end cap EC is integrally formed of a synthetic resin material, and includes a cover piece 13 for closing an opening end of the door molding M, a molding insertion piece 14 inserted into the door molding M, and a lifting piece of the lip piece 11. And a lip lifting piece 15.

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

The molding insertion piece 14 includes an inclined portion 14a and an upright portion 14b, and is formed in a cross-sectional shape such that it can fit inside the door molding M as shown in FIG. 1 or 3 as a whole. 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 there is a slight gap between the upper surface of the inclined portion 14a and the inner surface of the door molding M. It is to be done. 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 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 (FIG. 3).
reference). As shown in the figure, the connecting piece 17 extends so as to go under the lower end of the insertion base 4 in the first relief portion 5. Thus, the molding insertion piece 14 has such a length as to be inserted into a position corresponding to the second relief portion 7 of the door molding M, and a lip lifting piece 15 described below is provided at one end thereof with the joint pin 8. It is provided integrally at a position substantially corresponding to the vertical path.

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

Next, the operation and effect of the present embodiment 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 comes into contact with the side surface portion of the door panel P, and the lip piece 11 comes into contact with the door glass G in a state of crossing the elevating locus of the joint pin 8.

When the end processing of the door molding M attached in this manner is performed, the end face of the molding insertion piece 14 of the end cap EC is adapted 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 adapted to the inside of the flange edge 3, and the upright portion 14b is inserted into the base 4
And push it along. When this pushing is performed until the cover piece 13 comes into contact with the end face of the door molding M to close the opening face, the lip lifting piece 15 is pressed.
Receives the upright portion 14b of the portion corresponding to the second relief portion 7 of the door molding M inside. At this time, since the base of the lip piece 11 is directly pushed up by the pushing surface 18 of the lip lifting piece 15, the area around the pushed up part is forcibly deformed upright over a predetermined range (the imaginary line in FIG. 1). From the state shown by the solid line to the state shown by the solid line). As described above, since the lip lifting piece 15 is disposed at a position corresponding to the vertical path of the joint pin 8, the joint pin 8 is moved along with the door glass G up and down.
1 through the upright deformation portion. Therefore,
Although almost the entire range of the lip piece 11 is in sliding contact with the door glass G, 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 lip piece 11 being entangled unlike the related art.
Therefore, the operation of raising and lowering the door glass G can always be performed smoothly.

As described above, according to the end cap EC of the present embodiment, the lip lifting piece 15 is directly used by the lip piece 1.
1 to lift the joint pin 8
The interference avoidance with respect to is ensured. Also, instead of providing a dedicated member for lifting the lip piece 11, the lip lifting piece 1 is integrally formed using the existing end cap EC.
5, the configuration is simple. Further, a special operation for lifting the lip piece 11 is not required, and only the work of simply inserting the end cap EC is required, so that the working efficiency is excellent.

In this embodiment, the lip piece 11 is deformed so as to have a slight clearance with the joint pin 8. However, if the lip piece 11 is effectively prevented from being entangled, the lip piece 11 may be deformed. It is also possible to set such that sliding contact occurs. The object that the door molding M avoids interference is not limited to the joint pin 8, but may be another protrusion existing near the end of the door glass.
