Further, the electric motor 20 is arranged so that the axis of the output shaft 18 thereof is substantially aligned with the axis of the shaft 22.

More specifically, the exterior part 12 is composed of a base 42 and a hood 44, and the base 42 constitutes the bottom part of the exterior part 12, and a rectangular bottom plate 46 has a short top surface. The cylindrical first side surface 48 is extended, the electric motor 20 and the supporting member 26 are attached to the inside thereof, and the pillars 10 of the automatic opening / closing door are vertically installed and fixed to the four corners of the bottom plate 46. Therefore, the fixing hole 50 is formed. The hood 44 is formed in a cylindrical shape with an open lower end surface, and the shaft 22 can penetrate through the upper end surface, and a through hole 52 that can be brought into close contact with the side surface of the shaft 22 when penetrated is provided. In addition, two mounting holes 54 for mounting a first arm, which will be described later, are provided on the peripheral surface on a straight line parallel to the axial direction at predetermined intervals. The diameter of the attachment hole 54 is set to be slightly larger than the outer diameter of the first arm. The inner diameter of the hood 44 is slightly larger than the outer diameter of the first side surface of the base 42. As a result, the second arm and the third arm, which will be described later, are fitted from above the shaft 22 and the shaft 22 is inserted into the through hole 52, and the peripheral surfaces of the second arm and the third arm are inserted. The open lower end of the hood 44, which is screwed and fixed to, is fitted so that the inner peripheral surface thereof overlaps the outer peripheral surface of the first side surface 48 of the base 42, and is supported by a part of the shaft 22. The member 26, the electric motor 20, the battery 38, and the control unit 40 are hidden. When the shaft 22 rotates forward and backward, the hood 44 also rotates forward and backward together with the second arm and the third arm while the inner peripheral surface of the lower end thereof slides on the outer peripheral surface of the first side surface 48. ..

The first fixing member 32 has a fixing portion 30 at one end, and a first arm 56 having a screw threaded on the outer peripheral portion of the other end, and one end surface formed in an arc shape. The one end face is provided with a first screw hole 58 to which the screwed other end of the first arm 56 can be screwed and a second screw hole 60 for screwing the hood 44, and The other end is composed of a second arm 62 having an axial through hole 61 through which the shaft 22 can be passed. Further, the distance from the one end surface of the second arm 62 to the central portion of the shaft through hole 61 is formed to be slightly smaller than the inner radius of the hood 44. The second arm 62 is axially passed through the shaft 22, and is fixed by a screw on the lower end side of the shaft 22 so that one end thereof projects in a direction perpendicular to the axis of the shaft 22.

The second fixture 34 is formed in a disk shape with the first arm 56, and is provided with a first screw hole 58 and a second screw hole 60 on its peripheral surface, and has a central portion at the center. Is composed of a third arm 64 having an axial hole 61 through which the shaft 22 can pass. The radius of the third arm 64 is formed to be slightly smaller than the inner radius of the hood 44. The third arm 64 is axially passed through the shaft 22, is above the supporting position of the supporting member 26 of the shaft 22, and is spaced apart from the second arm 62 by the two mounting holes 54 provided in the hood 44. It is fixed to be the same as the interval. The first arm 56 is inserted into the attachment hole 54 from the outside of the hood 44 after the hood 44 is fixed to the second arm 62 and the third arm 64, and then the second arm 62 and the third arm 64 are inserted. The arms 64 are screwed and fixed in the respective first screw holes 58.

The solar cell 36 is attached to the upper end side of the shaft 22 protruding from the upper surface of the hood 44 by a metal fitting 66 capable of changing the elevation angle and the horizontal angle. The control unit 40 controls storage of electric power in the battery 38 and supply of electric power from the battery 38, and constantly monitors the states of the first switch 14 and the second switch 16. When the first switch 14 is pressed, the electric motor 20 is driven so that the gate 28 opens at a predetermined angle for a predetermined time. After the lapse of a predetermined time, the electric motor 20 is rotated in the reverse direction to close the gate 28. The same operation is performed when the second switch 16 is pressed. Further, the solar cell 36, the battery 38, the control unit 40, the electric motor 20, the first switch 14, and the second switch 16 are connected by a wiring material (not shown), and a power source and a signal are connected. Can be transmitted between the respective constituent members (see FIG. 4). In particular, the wiring between the solar cell 36 outside the outer casing 12 and the control unit 40 inside the outer casing 12 is structured so as to pass through the hollow shaft 22. Thus, when installing the gate 28, two pillars 10 of the automatic opening / closing door, which are assembled by assembling the respective constituent members as described above, are erected, and the gate 28 is attached to the pillar 10 of each automatic opening / closing door. This is completed by fixing the metal fitting 66 with the battery 36 facing the sun.

Next, the operation will be described. First, a person who wants to enter the gate presses the first switch 14 provided in front of the pillar 10 of the automatic opening / closing door. When detecting that the first switch 14 has been pressed, the control unit 40 causes a current to flow through the electric motor 20 and causes the output shaft 18 and the shaft 22 to rotate forward. Thereby, the hood 44 fixed to the second arm 62 and the third arm 64, the first arm screwed to the second arm 62 and the third arm 64, and having the fixing portion 30 at one end thereof. Since 56 rotates, the gate 28 attached to the fixed portion 30 opens. Further, when a preset time has elapsed, the control unit 40 causes the electric motor 20 to flow a reverse current to rotate the output shaft 18 and the shaft 22 in the reverse direction. As a result, the gate 28 is closed. In this way, the gate 28 is opened for a preset time, so that a person can enter the gate during that time. In addition, when a person inside the gate opens the gate 28 by pressing the second switch 16 provided on the rear surface of the pillar 10 of the automatic opening / closing door, the same as when pressing the first switch 14 described above. The gate can be opened.

As described above, the first switch 14, the second switch 16, and the like are provided, and the hood 44 that is touched by human hands, the first fixing tool 32 and the second fixing tool 34 protruding from the hood 44. , And the shaft 22 rotate forward and backward at the same time, it is not necessary to movably attach the first fixture 32, the second fixture 34, and the shaft 22 to the hood 44. Since it is not necessary to provide a notch for the second fixing tool 34 and the second fixing tool 34, each mounting part can have a closed structure, which prevents dust and rainwater from entering the inside of the pillar 10 of the automatic door. It can be prevented. Further, since there is no opening on the side surface of the hood 44, there is no risk of accidentally putting a finger in the opening and pinching the finger. Further, since the electric motor 20 is arranged such that the axis of the output shaft 18 thereof is substantially aligned with the axis of the shaft 22, it is possible to reduce the diameter of the pillar 10 of the automatic opening / closing door.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.
