Abstract

PURPOSE:To reduce the size of a gate door, by a method wherein a motor, a reduction gear, and a drive unit are incorporated in a gate column, the base part of an arm protruded from the gate column and horizontally pivoted centering around the gate column is coupled to the reduction gear, and the tip of the arm is mounted to the suspension base side of the gate door. CONSTITUTION:Hollow gate columns 1 are erected with a distance therebetween, a gate door 4 is openably mounted, and a drive unit 8 comprising a motor 6 and a reduction gear 7 is incorporated in the lower part of the gate column 1. The base part of each of arms 9 is secured to an output shaft 23 and the arms 9 are protruded outwardly of a casing 11. The arm 9 is protruded through a slit 24 formed horizontally in the lower part of the gate column 1, and the gate door 4 is made rotatable in a 90 deg. arc through running of the motor 6. The tip of the arm 9 is attached to a mounting metal 25 at the lower part of the gate door 4, and the arm 9 is rotatably mounted and protruded through the slit 24. This constitution enables opening and closing of the gate door through drive of an electric motor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the structure of a gate that opens and closes electrically.

[Prior art] In the conventional electric gate, as shown in Fig. 3, the gate post 1
A drive unit 2 is attached to the outer surface of the gate, and the drive unit 2 is connected to a gate 4 which is attached to the gate post 1 so as to be openable and closable with a hinge 3, and the drive unit 2 is linked by an interlocking arm 5, and the drive unit 2 drives the interlocking arm 5. By doing so, the gate 4 was rotated to open and close.

[Problems to be Solved by the Invention] In the conventional example described above, since the drive unit 2 is attached externally to the gatepost 1, there is a problem that a portion protrudes outside the gatepost 1, resulting in a poor appearance. together with drive unit 2
There is a problem that the interlocking arm 5 occupies space and becomes large.

The present invention has been made in view of the above points, and an object of the present invention is to provide an electric gate that can be driven by a drive unit built into the gate post, has a good appearance, and can be made small. There is something to do.

[Means for solving the problem] In order to achieve the above object, a drive unit 8 consisting of a motor 6 and a speed reducer 7 is built inside the gatepost 1, protrudes from the gatepost 1, and rotates about the gatepost 1 in a horizontal plane. The base of the arm 9 was connected to a speed reducer 7, and the tip of the arm 9 was attached to the hanging base side of a gate 4 which is attached to a gate post 1 so as to be openable and closable.

[Operation] With the above configuration, the drive unit 8 built into the gate post 1 can rotate the gate 4 via the arm 9 to open and close it.

[Example] As shown in FIG. 1, gate posts 1 are erected on the left and right at intervals, and a gate 4 is attached to each gate post 1 so as to be openable and closable. The gatepost 1 is hollow inside, and a drive unit 8 is built in the lower part of the gatepost 1.

This drive unit 8 is composed of a motor 6 and a reduction gear 7. This speed reducer 7 is constructed as shown in FIGS. 2(,), (b) and (c). The first output shaft of the motor 6
The shaft 10 is introduced into the casing 11, the first gear 12 of the first shaft 10 and the second gear 14 of the second shaft 13 are meshed with each other, and the third gear 15 and the third gear 15 provided on the second shaft 13 are engaged with each other. 3 axes 16
The fourth gear 17 of the third shaft 16 is meshed with the fifth gear 17 of the third shaft 16.
The tooth $18 and the sixth gear 20 of the fourth shaft 19 are meshed, and the seventh gear 21 of the fourth shaft 19 and the eighth gear 22 of the output shaft 23 are meshed. However, motor 6 drives the first axis 1.
0, the first gear 12, second gear 14, second shaft 13, third gear 15, fourth gear 17, third shaft 16, fifth gear
Gear 18, sixth gear 20, fourth shaft 19, seventh gear 21,
Power is transmitted in this order to the eighth gear 22 and the output shaft 23, and the output shaft 23 is rotated by being decelerated at an extraordinary reduction ratio. The base of an arm 9 is fixed to the output shaft 23, and the arm 9 is made to protrude outside from the casing 11, and the arm 9 is made to protrude from a slit 24 provided horizontally in the lower part of the gate post 1. This arm 9 is designed to rotate within a range of 90 degrees when driven by the motor 6, but a stopper and a detector are provided to prevent the arm 9 from rotating beyond a range of 90".The tip of the arm 9 is connected to a gate. The lower part of the arm 9 is attached to the metal fitting 25.There is no drive unit 8 in the upper part of the gatepost 1, but the base of the arm 9 is attached to the output shaft 2.
It is rotatably attached to a shaft located coaxially with 3, and the arm 9 is made to protrude from the upper slit 24,
The upper part of the gate 4 is attached to a metal fitting 25.

The electric gate is configured as described above, and by operating the switch and driving the motor 6, the arm 9 is rotated via the deceleration fi7, and the gate 4 is rotated to open and close the gate 4.

By switching between forward and reverse rotations of the motor 60, the gate 4 can be opened or closed, and by stopping the motor 6 halfway, the gate 4 can be stopped at any angle.

[Effects of the Invention] As described above, the present invention incorporates a drive unit consisting of a motor and a reducer inside a gatepost, and connects the base of an arm that protrudes from the gatepost and rotates in a horizontal plane around the gatepost to the reducer. , the tip of the arm is attached to the hanging base of the gate that is attached to the gatepost so that it can be opened and closed freely, so the gate can be electrically opened and closed via the arm using the drive unit built into the gatepost. Even if it can be opened and closed, the appearance will not be as bad as in the past, and it will also be smaller.
