Description

[Detailed Description of the Invention] Field of Application of the Invention The present invention relates to a hinge used for automobile doors, building doors, etc.

Conventional technology Conventional wide-angle door hinges, for example, hinges for opening 180 degrees, have a shaft that connects the left and right mounting plates that protrude from the door surface, so they are not used as hinges for automobile side doors. In some cases, the axle part was protruding from the outside of the car body.

Problems to be solved by the invention Since the conventional technology was as described above, the shaft portion was exposed to the outside, making it unsightly, and at the same time, there were problems in terms of safety and air resistance during driving.

This invention connects the fixed part and the movable part that constitute the hinge in a rotatable manner by a link, and the rotation angle of the fixed part and the link and the movable part and the link is controlled by a gear that is pivotally supported on the link. By interlocking control with The structure is such that the center gradually moves inward.

With such a structure, it is possible to provide a door that can be opened widely, such as 180 degrees, even if the axis of the hinge does not protrude from the surfaces of the main body and the door.

Means for Solving the Problem The configuration of the present invention is such that the gear 1 is fixed to the fixed part 10 and the gear 4 is fixed to the movable part 11.
Two or an even number of gears 2, 3 are interposed and meshed between the shafts 5, 6, 7, 8 which are loosely fitted into these gears 1, 2, 3, 4 as well as the fixed part 10 and the movable part 11.
are fixed to opposing links 9,9.

Function Since the present invention is configured as described above, when the movable part 11 is pulled clockwise with respect to the fixed part 10 as shown in FIG.
3, 4 and the movable part 11, the gear 2 moves in an arcuate trajectory around the shaft 5 of the gear 1, and at the same time gear 2, which is meshed with the gear 1, rotates clockwise and gear 3 rotates counterclockwise. Accordingly, the gear 4 rotates clockwise. Since the gear 4 is fixed to the movable part 11, the movable part 11 also rotates clockwise about the shaft 8. As a result, the movable part 11 rotates clockwise around the shaft 5, and at the same time rotates clockwise around the shaft 8, which rotates clockwise around the shaft 5, and reaches the door open state. .

Contrary to the above, when closing an open door, if the movable part 11 is pushed counterclockwise, the links 9, 9 are reversely displaced about the shaft 5 in the same way as above, and at the same time gears 2, 3, and 4 are moved. rotates, and the movable part 11 is attached to the shaft 5.
At the same time, the door is rotated counterclockwise around the shaft 8, and at the same time, the door is rotated counterclockwise around the shaft 8, so that the door is closed.

Embodiment An embodiment will be explained with reference to FIG. 1, which shows the opening/closing operation of the back door of a van-type vehicle.A gear 1 is fixed between a U-shaped fixed side mounting plate 10 serving as a fixed part, and this gear is Center of 1 and fixed side mounting plate 1
The shaft 5 is loosely fitted through the shaft 5, and the gear 4 is fixed between the U-shaped movable side mounting plate 11 which becomes a movable part, and the center of this gear 4 and the movable side mounting plate 11 are fixed.
The shaft 8 is passed through and loosely fitted. Furthermore, links 9 and 9 are installed and fixed to both ends of the shafts 5 and 6 so as to face each other, and a gear 2 that meshes with gear 1 is meshed with gear 2 and gear 4 between links 9 and 9. gear 3
are inserted, and both ends of shafts 6 and 7 loosely fitted through the centers of gears 2 and 3 are fixed to links 9 and 9, respectively. Then, the fixed side mounting plate 10 is fixed to the main body 12 near the back door opening at the rear of the van type vehicle, and the movable side mounting plate 11 is fixed to the door 13.

According to the embodiment, when opening the door 13, pull the door 13 clockwise relative to the main body 12 in the figure, and at the same time, the links 9, 9 move the gears 2, 3,
4 and the movable mounting plate 11, it rotates clockwise about the shaft 5. That is, the shaft 8 is displaced clockwise while drawing an arcuate locus around the shaft center O of the shaft 5, with the radius R being the length from the shaft center O of the shaft 5 to the shaft center P of the shaft 8. At the same time, gear 2 meshing with gear 1 rotates clockwise, gear 3 rotates counterclockwise, and gear 4 rotates clockwise accordingly. Since the gear 4 is fixed to the movable mounting plate 11 and the door 13 is fixed to the movable mounting plate 11, the door 13 rotates clockwise about the shaft 8. As mentioned above, since the shaft 8 rotates clockwise around the shaft 5, the door 13 performs a combined operation of rotation around the shaft 5 and rotation around the shaft 8. do. That is, the rotational relationship between the main body 12 and the links 9, 9 and the rotational relationship between the door 13 and the links 9, 9 are controlled in conjunction with gears 1, 2, 3, and 4. , 3, and 4.

If the ratio is 1:1:1:1, when links 9 and 9 rotate 90 degrees clockwise around shaft 5, gear 2 will rotate 180 degrees clockwise and gear 3 will rotate 180 degrees counterclockwise. At this time, the gear 4 rotates 180 degrees clockwise together with the door 13. When looking at the shaft 8 in this state, it is located outward by a length corresponding to the radius R from its original position. Thereby, a door opening angle of 180 degrees can be obtained without interference between the main body 12 and the door 13.

Therefore, when the hinge having the structure according to the present invention is used as an automobile door hinge, it is possible to provide a door that can be opened at a wide opening angle (for example, 180 degrees) even if the axis of the hinge does not protrude from the surface of the automobile body or door. It is safe because there is no protrusion to the outside of the vehicle body, and it also has the advantage of reducing air resistance during driving.
