The present invention relates to a two-door open and close automatic door, and more particularly to a two-door open and close automatic door that can be opened and closed by manpower in case of emergency.

The door of the building that is opened or the door of the interior is made of heavy weight such as steel or thick glass so that it is not easily opened by wind, etc. This is a problem that the elderly, the disabled, and children cannot easily open. In the case of a single door, the radius of rotation corresponding to the width of the door is large, and in the case of a disabled person who relies on a wheelchair, the door is very difficult and inconvenient to pull the door open.

In order to solve this problem, Figure 1 and Figure 2 shows the 'automatic opening and closing device' of the prior art registered utility model No. 20-0184277, such a structure is "inside the top of the rotating transmission shaft support 110, and at the bottom The door 100 having the manual hinge groove 120 installed therein, a manual hinge 300 installed on the floor to support the lower end of the door 100 and being rotatable, and a driving unit for rotating the door 100. In the configuration consisting of the upper door frame 200,

Figure 3 is a view showing the overall structure of the present invention, Figure 4 is an enlarged view showing a portion generating power for opening and closing the door (300,300 '), a pair of doors (300,300') opening and closing in the form of a case. It has a structure, and has a power unit 400, a power transmission unit 500, the first and second link unit 600, 700 on the upper side of the door (300, 300 ') for automatic opening and closing.

The power unit 400 is provided with a drive motor 420 inside the housing 410 fixed to the upper wall or door frame of the door (300,300 '), the lower portion of the drive motor 420 the rotation of the drive motor 420 Reducer 430 is provided to reduce the speed.

The shaft 431 of the reducer 430 protrudes outward from the bottom of the housing 410 and is exposed.

A power transmission unit 500 is provided below the housing 410, and the power transmission unit 500 includes a drive gear 510 connected to an axis 511 of the reducer 430 and an upper shaft 511. It is composed of a driven gear 520 is located side by side at the side of the gear 510 and meshes with the drive gear 510, the shaft 521 of the upper side of the driven gear 520 is drawn into the housing 410 to the housing Rotation is installed by a bearing 530 fixed inside the 410.

The shaft 512 on the lower side of the drive gear 510 is formed as a square body, and is coupled to the shaft fixing hole 611 in the form of a square hole of the first link unit 600, and the lower side of the driven gear 520. Similarly, the shaft 522 is formed in a rectangular rectangular body and is coupled to the shaft fixing hole 711 of the second link unit 700. The first link unit 600 is connected to the first door 300 and the second link. The part 700 is connected to the second door 300 ′.

The first link unit 600 and the second link unit 700, which uses a known technique, is the same as the link structure of the door check described in Patent 10-0899783.

That is, when a rotational force is applied to the main links 610 and 710, the auxiliary links 620 and 720 are pushed or pulled to open and close the doors 300 and 300 '. Since such a structure is too general, a specific structure will not be described.

Meanwhile, as shown in FIG. 5, the drive gear 510 includes an upper drive gear 513 and a lower drive gear 515 that are separated in the lateral direction, and are in contact with each other, that is, the lower surface of the upper drive gear 513. Permanent magnets 514 and 516 are provided on the upper side of the lower driving gear 515, respectively. A plurality of these permanent magnets 514 and 516 are installed while alternating the N pole and the S pole along the periphery of the centers 511 and 512, respectively. Each of these permanent magnets 514 and 516 has a similar fan shape.

Accordingly, the N pole permanent magnet of the upper drive gear 513 and the S pole permanent magnet of the lower drive gear 515, and the S pole permanent magnet of the upper drive gear 513 and the N pole permanent magnet of the lower drive gear 515. The contact force is maintained by the attraction force.

It describes the operation state of the present invention.

When the driving motor 420 is driven in the forward direction by a sensor or a button when the doors 300 and 300 'are opened, the driving gear 510 rotates clockwise and the driven gear 520 rotates counterclockwise. As the first link unit 600 and the second link unit 700 rotate backwards, the doors 300 and 300 'are opened as shown in FIG.

On the contrary, when the driving motor 420 is driven in the reverse direction, the drive gear 510 rotates in the counterclockwise direction and the driven gear 520 rotates in the clockwise direction so that the first link part 600 and the second link part ( 700 is rotated forward to close the door (300,300 ') as shown in Figure 6 (a).

At this time, the door (300,300 ') is not loaded with an obstacle, so the upper drive gear 513 and the lower drive gear 515 rotates the door (300,300') by the attraction of the permanent magnet (514,516) together. It will open and close.

Of course, the driven gear 520 similarly rotates the upper driven gear 523 and the lower drive gear 525 together by the attraction force of the permanent magnets 524 and 526.

On the other hand, in an emergency such as a power outage, if a person pushes one of the doors 300 and 300 'or both doors, the pushing force is transmitted through the first link part 600 or the second link part 700. It is transmitted to the lower driving gear 515 or the lower driven gear 525 of the drive gear 510, the driven gear 520.

At this time, since the load is applied to the upper drive gear 513 by the reduction gear 430, the upper drive gear 513 does not rotate, and only the lower drive gear 515 slips off due to slip, and similarly, the upper driven gear While 523 is also fixed, only the lower driven gear 525 slips due to slip.

In addition, the permanent magnet 514 and the permanent magnet 516 of the drive gear 510, and the permanent magnet 524 and the permanent magnet 526 of the driven gear 520 is the polarity of the door (300,300 ' ) Is easy to rotate.

If a person does not apply force to the doors 300 and 300 'while the doors 300 and 300' are opened, the permanent magnets 514 and 516 and 524 and 526 are coupled to each other by the attraction force and remain open.

Of course, when the door (300,300 ') is closed by the force of the human will operate as well.
