BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door hinge mounting device, and more particularly, to a door hinge mounting device most suitable for use in a door hinge portion of an automobile.

[0002]

2. Description of the Related Art As shown in FIG.
The back door 2 has a double-door type that opens and closes in the left and right directions of a rear opening. The hinge 3 is a butterfly type as shown in FIG. 6, and a joint 3 a projects outside the rear side outer panel 4. Outer types are common. However, since the hinge 3 is exposed to the outside and protrudes, the outer type has disadvantages such as poor appearance, easy rust, and damage or injury due to collision.

Therefore, as shown in FIG. 7, a swan neck type is used for the hinge 5, and the neck 5 a is formed in the space 9 formed by the opening 7 formed in the rear pillar panel 6 and the rear side outer panel 8. Insert the bearing part 1
There is an inner type that is rotatably supported by a zero. However, in this inner type, since the lateral width D of the opening 7 through which the hinge 5 enters / exits becomes large, there is a possibility that a limb or the like may be caught in the opening 7 when the door 11 is open, and the safety is reduced. There was a problem.

[0004] In order to ensure this safety, Japanese Utility Model Laid-Open No. 60-38821 discloses, as shown in FIG.
A door 15 including an outer panel 12 and an inner panel 13 and having a trim member 14 provided on the vehicle interior side is attached to a pillar 17 by a hinge member 16, and a cover member 18 having a predetermined width in the vertical direction of the vehicle body is provided. There is disclosed one in which one end is fixed to a pillar 17 side and the other end is slidably inserted into a gap 19 formed between the inner panel 13 and the trim member 14.

[0005]

However, in the case of Japanese Utility Model Application Laid-Open No. 60-38821, the trim member 14 cannot be fixed to the inner panel 13 at the portion where the gap 19 is formed. When the door 14 is opened and closed, there is a possibility that the cover member 18 may flutter and generate an abnormal sound, and when the door 15 is opened and closed, the cover member 18 always slides in the gap 19, so that the sliding wear is severe. Further, since the cover member 18 slides in the gap 19 with its own strength, there is a problem that it is difficult to ensure a smooth sliding operation of the cover member 18.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. When the swan-neck hinge reaches a predetermined rotation position, the hinge opening is closed. An object of the present invention is to provide a device that can maintain safety in a state and can guarantee safety. The gist of the invention is to fix one end of a swan-neck hinge to a door and connect the other end of the door to a door mounting portion. When the door passes through the opening on the side and pivotally attaches to the bearing, the base end of the cover body that can pass through the opening and closes the opening pivotally attaches to the bearing, and the door opens at a predetermined opening angle. The door hinge mounting device is characterized in that the hinge and the cover main body engage with each other to rotate the cover main body together to close the opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to an embodiment shown in FIGS. 1 to 4. FIG. 1 is a cross-sectional plan view showing a closed state of a vehicle door to which a door hinge according to the present invention is applied.
FIG. 2 is a cross-sectional plan view showing a state in which the vehicle door is being opened, FIG. 3 is a cross-sectional plan view showing a state in which the opening of the vehicle door is completed, and FIG.
FIG. 3 is a perspective view of the door hinge.

In the drawing, reference numeral 1 denotes a door provided at a rear opening of an automobile, which is a double-door type which is opened and closed in the left-right direction by an iron hinge 2 having a predetermined vertical length. The hinge 2 is of a swan-neck type in which one end 2a in a plan view is linear and the other end (neck portion) 2b is bent in a U-shape. The neck 2b is inserted from a rectangular opening 4 formed in the rear pillar panel 3a of the body 3 into a space 5 formed by the rear side outer panel 3b, and is fixed by a bearing 6 fixed in the space 5. It is rotatably supported. A striker 7 is provided on the outer surface of the neck 2b of the hinge 2 so as to project therefrom.

Reference numeral 8 denotes a plastic cover body for closing the opening 4, a cover 9 in which a flat plate closing portion 9b is connected to the arc plate 9a at an acute angle, and a side plate 9c for closing the top and bottom of the cover 9. The upper and lower lengths of the cover 9 are slightly shorter than the upper and lower lengths of the opening 4, and the width of the flat plate closing portion 9 b is slightly shorter than the width of the opening 4. At the free end of the plate portion 9a, a stopper 10 made of resin that can freely contact the striker 7 is provided. Then, the cover main body 8 is
The neck 2b of the hinge 2 is fitted, and the base end of the side plate 9c is pivotally mounted coaxially with the bearing 6 of the hinge 2.

Therefore, when the door 1 is closed, the cover body 8 is located in the space 5 and the stopper 10 is located at the inner peripheral edge of the opening 4. When the rotation starts around the portion 6 as a fulcrum and the neck portion 2b of the hinge 2 comes out of the opening 4, the hinge 2
The striker 7 fixed to the stopper 1 of the cover body 8
0, the cover body 8 is pulled out of the space 5 together with the door 1, and the cover body 8 is closed at the opening end position of the door 1.
Of the flat plate 9b closes the opening 4. Then, when the door 1 is closed from the opening end position, the hinge 2 is closed.
When the door 2 is further closed, the cover body 8 is forcibly pushed back to the original position. In the above embodiment, an example in which the present invention is applied to the vehicle door 1 has been described. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a door of a warehouse or the like.

[0011]

As described above, the door hinge mounting device according to the present invention fixes one end of the swan neck hinge to the door,
When the other end neck portion is pivotally connected to the bearing portion through the opening on the door mounting portion side, the base end of the cover body which can pass through the opening portion and closes the opening portion is pivoted to the bearing portion. When the door reaches a predetermined opening angle, the hinge and the cover body are engaged to jointly rotate the cover body to close the opening, so that the opening is closed at the predetermined opening angle of the door. Since it can be held in a state, safety is assured without limbs or the like being caught in the opening, and the appearance also improves. In addition, the cover body has no sliding parts with respect to the hinge, so durability is improved, and no abnormal noise is generated. In addition, since the cover body is pivoted coaxially with the hinge, the installation space is small. In addition, there are various effects such that the hole can be stably closed without being affected by the mounting accuracy of the door mounting side.
