Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a corner piece mounted on a door of an automobile, and is suitable when high rigidity is required for fixing a door mirror, for example.

<Prior Art> With the recent demand for improved design of door glass and the increase in automobiles with door mirrors, as shown in FIG. 9, the door belt line 11 in the door closed state and the inclined pillar (front) are provided. The demand for the door corner piece 1 that closes the corner between the pillar and the pillar 12 is increasing. In this specification, a corner piece for a front door of a cashless door will be described as an example, but the same applies to a corner piece for a cashmere door and a corner piece for a rear door.

The door corner piece 1 has, for example, the fourth, sixth, seventh,
It was as shown in FIG.

It has an outer shape (usually a triangle) that closes between the door belt line 11 in the door closed state and the front pillar 12 above it.
Glass storage groove 5 that can store the corner 4 of the door glass G
A corner piece portion 2 having a substantially U-shaped cross-section that opens downward so as to form a groove, and an inner plate 2a and an outer plate 2b of the corner piece portion 2 that forms the glass storage groove 5 and extend downward. And a substantially triangular inner mounting leg portion 3a, and an outer mounting leg portion 3b, which is slightly smaller than the inner mounting leg portion 3a and has a bulged tip. Corner piece 2
At the opening edge of the glass storage groove 5, there is a glass run portion 6 composed of a pair of strip lips that are close to each other on the tip side.
The shape retaining ability of the corner piece portion 2 is maintained by the sheet metal insert 7 having a U-shaped cross section and covered with the polymer elastic body 8. The sheet metal insert 7 and the above-mentioned inner and outer mounting leg portions 3a and 3b are integrated.

As shown in FIG. 7, the door corner piece 1 having the above-described configuration has bolt holes 31, which are formed in the mounting leg portions 3a, 3b.
It is fixed to the door sheet metal 13 by passing bolts through 33 and 35. However, the corner piece 1 in which the mounting leg portions 3a and 3b are connected by the corner piece portion 2 having a U-shaped cross section
Had no so-called pillar, and there was a problem in terms of structural strength. In other words, when a heavy electric door mirror is arranged on the corner piece 1, there is a possibility that distortion may occur due to impact force when the door is opened and closed, and wind noise may be generated.

Therefore, as shown in FIG. 5, in the vicinity of the intersection of the front pillar facing side 9 of the corner piece portion 2 and the door belt line 11, a reinforcing bridge 10 having a U-shaped cross section is provided on the inner and outer mounting leg portions 3a and 3b. (Usually fixed by welding).

In addition, the reason why the reinforcing bridge 10 is installed in the above-mentioned region is to avoid interference with the corner portion 4 of the door glass G housed in the corner piece 1.

<Problems to be Solved by the Invention> As shown in FIG. 5, when the reinforcing bridge 10 is installed between the mounting leg portions 3a and 3b, the corner piece 1 surely becomes structurally strong. However, each mounting leg 3a, 3b
The structure of welding the reinforcing bridge 10 as a separate member causes a problem that the number of manufacturing steps and the manufacturing cost of the corner piece are significantly increased.

<Means for Solving Problems> This invention was made in consideration of the above problems,
A bolt that extends from the side of the outer mounting leg that intersects the front pillar, is bent so that it can contact the inner mounting leg, and can be tightened together with the inner mounting leg to the door sheet metal. It is characterized by comprising a reinforcing bridge having a through hole formed therein.

<Operation> As a result, the reinforcing bridge is integrated with the outer mounting leg, and the reinforcing bridging and the inner mounting leg are fixed together by bolting the inner mounting leg to the door sheet metal. You can do it at the same time.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings (FIGS. 1 to 3).

The same parts as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

The corner piece 21 of the embodiment includes a corner piece portion 2 having the same shape as that of FIG. 6, and FIG. 1 shows the sheet metal insert 7 and the inner and outer mounting leg portions 3a and 3b.

Further, in the corner piece 1 shown in FIG. 6, this corner piece 21 is provided on the outer mounting leg portion 3b so as to extend from the side 23 on the side intersecting the front pillar 12 substantially in the same plane, and the inner mounting leg portion. It is characterized in that a reinforcing bridging 25 is formed so that it can be brought into contact with 3a. As shown in FIG. 3, a bolt through hole 27 is formed in a portion of the reinforcing bridge 25 that abuts the inner mounting leg portion 3a. The nut 28 is welded to the reinforcing bridge 25 so that the threaded hole 29 communicates with the bolt through hole 27. When the corner piece 21 is fixed to the door sheet metal 13, this nut 28 is used for the door sheet metal inner 1.
It receives a bolt inserted from the 3a side.

As the polymeric elastic material 8 for covering the sheet metal insert 7 in the corner piece portion 2, CR, II having good weather resistance is used.
A rubber such as R, EPDM or polyblend, or a thermoplastic elastomer such as polyolefin or polyvinyl chloride is used. The molding means is injection or transfer.

Further, various through holes shown in the sheet metal insert 7 in FIG. 1 are for setting the door mirror.
The cord connected to the motor or the like in the door mirror is installed in the door assembly from the space 26 surrounded by the lower end of the hypotenuse facing the front pillar 12 of the sheet metal insert 7, the inner and outer mounting legs 3a and 3b, and the reinforcing bridge 25. Be guided inside.

The corner piece 21 of the embodiment having the above structure is attached to the door sheet metal 13 as shown in FIG.

The inner and outer mounting leg portions 3a and 3b are fixed to the door sheet metal 13 by bolting in the same manner as in the conventional example, and the outer mounting leg portion 3b has a bolt hole 3 formed in the tip bulging portion.
1 through the bolt A, and is fastened and fixed to the door sheet metal outer 13b. Reference numeral 32 is a weld nut.

Two bolt holes 33, 35 are bored in the inner mounting leg portion 3a, and a bolt B is passed through the bolt 33 on the tip side,
The tip side portion of the inner mounting leg portion 3a is the door sheet metal inner 1
It is fixed to 3a. The bolt hole 35 on the base side is formed in the vicinity of the side of the inner mounting leg 3a on the side intersecting the front pillar 12, and communicates with the bolt through hole 27 of the reinforcing bridge 25 described above. Then, when the bolt C is screwed in from the door sheet metal inner 13a side, the base side portion of the inner mounting leg portion 3a and the reinforcing bridge 25 are fastened together. Therefore, the reinforcing bridge 25 is installed between the mounting leg portions 3a and 3b, and the structural reinforcement of the corner piece 21 can be achieved.

<Effects of the Invention> As described above, according to the present invention, the reinforcing bridging is extended from the outer mounting leg portion so that the inner mounting leg portion and the door sheet metal can be fastened together. The reinforced bridging is now an integral part of the outer mounting leg.
Therefore, the number of parts of the corner piece is reduced as compared with the conventional product shown in FIG. Furthermore, since the reinforcing bridging, which is integrated with the outer mounting leg, can be fixed to the inner mounting leg at the same time when the inner mounting leg is fixed to the sheet metal of the door, a reinforcing bridge is provided. However, the man-hours for fixing them are unnecessary.

Thus, according to the corner piece of the present invention,
Not only can the corner piece of the conventional example shown in FIGS. 6, 7 and 8 be fixed to the door sheet metal with the same man-hours, but the man-hours and manufacturing costs of the corner piece itself are significantly larger than those shown in FIG. It will be reduced.

That is, according to the present invention, it is possible to provide an inexpensive and sturdy corner piece for an automobile.
