However, according to the structure described in Patent Document 1, in addition to the seamless frame (20), separate members such as the upper side design member (21) and the upright side design member (22) are required. Since the side design member (22) is a combination of the vertical column main member (23) and the vertical column sub member (24), the side design member (22) has a large number of parts, and these members must be overlapped with each other with high accuracy. There is a problem that the work becomes complicated, and the cost is high.
In addition, the upper side design member (21) and the upright column main member (23) need to be partially excised, so that the processing becomes complicated.
In addition, the upper side design member (21) and the upright column main member (23) overlap the groove bottom surface portion (21f) of the upright column main member (23) with the upper support surface (23f) of the upper side design member (21). Therefore, there is a problem that the strength is inferior to that of fixing by welding as in the prior art.

  In addition, the structure described in Patent Document 2 can be handled only by an extruded product by changing the elastic contact position of the opening seal (30) attached to the body side by attaching the block (40) to the sash (20). Since the roof side sash 2 and the pillar side sash 3 constituting the door 1 intersect at an acute angle (θ), the corner portion X becomes an edge shape, and as a result, a molded product is required. It does not solve such problems.

Furthermore, in the corner part X, since the corner piece material 50 and both sashes 22 and 23 are connected by welding, it is excellent in strength.

(Second Embodiment)
Next, an automotive door structure according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a perspective view showing an automobile door structure according to the second embodiment of the present invention, and FIG. 7 is an enlarged cross-sectional view showing an essential part of joining of the automobile door structure shown in FIG. FIG. 8 shows a state in which the door weather strip, the sub seal part, and the glass run are attached to the automobile door structure according to the second embodiment of the present invention, and is an enlarged sectional view taken along line FF in FIG. .
In the door structure for automobiles according to the first embodiment of the present invention, both the metal sashes 22 and 23 are joined and joined at the corner portion X in the same manner as the metal corner piece material 50 by welding. In the automobile door structure according to the second embodiment, the corner piece material 60 is resin-molded, and the resin corner piece material 60 and the metal sashes 22 and 23 are joined and joined together. Further, in place of the piece-side fitting recess 52 formed in the corner piece material 50 of the first embodiment, the corner piece material 60 of the second embodiment forms a guide portion 62, which is used as a door weather strip support portion. It is a function.

In addition, the piece side frame main body part 61, the piece side extension part 63, and the protrusion piece 64 of the corner piece material 60 are the piece side frame main body part 51 of the corner piece material 50, the piece side extension part 53, and the protrusion. Although the material is different from that of the piece 54, it has substantially the same shape.
In the first embodiment, the covering piece 31c is provided on the sub seal portion 31 so as to cover the exposed part of the piece side extending portion 53. However, in the second embodiment, the covering piece 31c is not provided on the sub seal portion 31. The cross-sectional shape is the same as that of the sub seal portion 31 (FIGS. 2 and 3) attached to the sashes 22 and 23. This is because, when the corner piece material 60 is made of resin, the color of the resin can be adjusted. Therefore, even if the piece side extending portion 63 between the door weather strip 30 and the sub seal portion 31 is exposed, an aesthetic appearance is achieved. It is because it does not spoil.

  As shown in FIGS. 6 and 7, the corner piece material 60 and the sashes 22, 23 are fitted together with protruding pieces 65, which protrude from both ends of the corner piece material 60 toward the sashes 22, 23. The projections 67 and 68 provided on the inner side of the vehicle 66 are fitted into the holes 22e and 23e formed in the frame main body portions 22a and 23a at the ends of the sashes 22 and 23, and joined. At this time, the protruding pieces 65 and 66 formed on the corner piece material 60 are inserted into the bag-shaped frame main body portions 22a and 23a, respectively.

The guide portion 62 formed on the corner piece material 60 is a flat surface having no concave portion and extends from the outside of the vehicle to the inside of the vehicle, and continues from the upper edge side of the door 1 to the pillar side through the corner portion X. The mounting base portion 30a of the door weather strip 30 integrally extruded is curved so as to be supported from the bottom surface.
The ends of both sashes 22 and 23 are joined and connected to the corner piece material 60 so that the fitting recesses 22b and 23b of both sashes 22 and 23 are connected to the guide portion 62 of the corner piece material 60. Yes.

According to this, the guide part 62 of the corner piece material 60 should just be curved so that the door weatherstrip 30 can be supported, and it fits like the piece side fitting recessed part 52 of the corner piece material 50 of 1st Embodiment. Since there is no need to provide a joint recess, the manufacturing is simple. In this case, in the vicinity of the center of the curved corner portion X, a normal clip may be used in which perforations are provided in both the guide portion 62 and the door weather strip 30 and both are fixed while passing through the perforations.
Note that a fitting recess such as the piece-side fitting recess 52 of the corner piece material 50 is integrated with the guide portion 62 of the corner piece material 60, integrally or intermittently separately, or only at the center of the corner. You may make it provide in.

  In the second embodiment of the present invention, the resin corner piece member 60 and the metal sashes 22 and 23 are joined and joined together, but may be joined by adhesion using an adhesive. .
