DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door device, and more particularly, to an automatic door device in which a door body opens and closes while moving and rotating laterally.

[0002]

2. Description of the Related Art In the prior art, a door device for rotating a door body while laterally moving the door body is provided with grips on both sides of the door body, and a person directly grips the grips to hold the door body. When the door is pressed, the door main body moves laterally while rotating, and opens.

[0003]

In the above prior art, the door body is rotated while the door body is moved laterally.
As the space for opening and closing is narrowed, the door can be opened without moving the wheelchair etc., and when the door is fully opened, the door body can be oriented at a substantially right angle to the door, No need for a door pocket like a sliding door
If a small space in front of the door could be secured, it could be installed anywhere, and the door could be opened lightly and easily by a direct push operation of a person. However, for a person in a wheelchair, a severely disabled person, or the like, the door is manually opened and closed, which is ultimately inconvenient.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide the above-mentioned automatic door device in which opening and closing operations are automatically performed.

[0005]

At the same time, a movement and rotation support mechanism 6 provided on the opening movement side of the upper part of the door body 5 rotatably supporting the door body 5, and the rotation of the door body 5 as the door body 5 moves laterally In order to support the vertical movement of the door body that moves and rotates, one end of the door frame 2 is supported by the shaft 15 on the closing movement side of the door, and the other end is supported by the shaft 15. An upper support arm 7 whose end is pivotally supported on an upper portion of the door main body 5 by a shaft 18;
A lower support arm 8 pivotally supported by a shaft 19 at an appropriate portion below the lower arm and a sensor 9 for forcibly rotating the upper support arm 7 by detecting that a person has approached the door. Arm drive mechanism 10 to be operated
It consists of The arm drive mechanism 10 is fixed to a drive motor 12 provided in the upper support arm 7 made of a pipe-shaped member with a drive shaft 11 protruding upward, and a drive shaft 11 driven and rotated by the drive motor 12. And a push-pull chain 14 sent out and retracted by the sprocket 13. One end of the push-pull chain 14 is attached to a chain attaching portion 17 of the doorway upper frame 3.

When the sensor 9 detects a person or the like, the drive motor 12 opens and operates to open and rotate the sprocket 13. As a result, the meshed push-pull chain 1
4 starts the feeding operation and becomes a rod-shaped member that stretches out.
4, the upper support arm 7 is pushed in the opening direction of the door together with the sprocket 13 that rotates and rotates about the shaft 15 on the doorway side. The lower support arm 8 also rotates together with the upper support arm 7, and the two support arms 7, 8 pull the door body 5 to open and move and rotate, and move the door to a position orthogonal to the doorway frame, thereby opening the doorway. To release.

When the sensor 9 stops detecting a person or the like, the drive motor 12 closes or rotates in reverse, and the sprocket 13 opens and rotates in reverse. The push-pull chain 14 meshing with the sprocket 13 starts the retraction operation, and the sprocket 13 moves in the reverse direction while rotating in the reverse direction according to the pushed-pull chain 14 to be retracted. With the sprocket 13 moving in the reverse rotation,
The support arm 7 is retracted in the door closing direction. Both the upper support arm 7 and the lower support arm 8 rotate in the opposite directions about the shaft 15 at the door support side as the axis, and the support arms 7, 8
Pushes the door body 5 to cause the door to close and rotate, move the door to a position where it fits into the door frame, and close the door.

The distance between the position where one end of the upper support arm 7 is supported on the upper portion of the door body 5 by the shaft 18 and the position of the sprocket 13 fixed to the drive shaft 11 on the upper support arm 7 is determined by the distance between the door and the door. Determines the magnitude of the force required for pushing and closing. According to the leverage principle, the smaller the distance between the two positions, the less the force required to open and close the door. In any case, the present invention has an effect that the force required to operate the support arm 7 is much smaller than the force required to open and close the door with the door grip 16.

Instead of the push-pull chain, a spiral wire formed by spirally winding a metal wire around a metal wire may be used.

0. In the second embodiment, the arm driving mechanism 49 can be attached regardless of the size and the shape of the upper support arm 40, and the structure is simple.
This has the effect of keeping costs low.

[Third Embodiment] FIGS. 13 to 15 are explanatory diagrams of the operation of the third embodiment of the present invention. FIG. 13 is a schematic plan view showing a closed state of the door body in the third embodiment of the present invention, FIG. 14 is a schematic plan view showing a state in which the door body of the third embodiment is being opened, and FIG. FIG. 13 is a schematic plan view showing a state where a door body of the third embodiment is completely opened. The differences between the third embodiment and the first embodiment are as follows. An arm drive mechanism 49 for forcibly rotating the upper support arm 40 around the shaft 43 is provided.
The arm driving mechanism 49 is provided on the upper frame 32 of the doorway frame 31, and is described below. The lower surface of the drive motor 50 is attached to the lower surface of the upper frame 32, and the drive shaft 51 projects downward from the lower portion of the drive motor 50, and the sprocket 52 is fixed to the drive shaft 51. The sprocket 52 is meshed with a rod-shaped push-pull chain 53. The tip of the push-pull chain 53 is attached to the upper support arm 40. On the opposite side, a chain guide 57 is attached to the lower part of the drive motor 50 via a mounting bracket 55. Installed. In the first embodiment, when the upper support arm is short, it may be impossible to incorporate the arm drive mechanism 49 including the push-pull chain 53 therein. Since there is no such restriction, there is an advantage that any type of arm drive mechanism can be attached.

[0024]

As described above, the present invention has the following advantages. That is, by detecting that a person has approached the door with a sensor or the like, or by manually turning on a switch,
Since the arm drive mechanism for forcibly rotating the support arm operates, an automatic door device that automatically performs lateral movement and open rotation of the door by rotating the support arm is realized. That is, a conventional door with the purpose of reducing the opening / closing space of the door when moving a wheelchair or the like needs to perform an operation that is extremely painful for a wheelchair user to open and close the door manually. The disadvantage is eliminated, and the door is automatically opened and closed by the sensor. In addition, since the arm drive mechanism is provided on the support arm, an automatic door device that achieves the above-described effect without newly taking up space is realized. Further, by using a push-pull chain, the support arm can be rotated and the door body can be moved and rotated with a small force,
It has the effect of achieving stable door opening and closing with a small motor. Further, by setting the mounting position of the arm drive mechanism on the side surface or the upper frame of the upper support arm, any form of the arm drive mechanism can be used, and the effect of reducing costs can be achieved.
