JPH0620856U - Automatic door controller - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] To provide a controller for an automatic door that does not affect moisture and has few failures. [Structure] A necessary mechanism is housed in the outer casing 1, and a left and right rotating arm 61 connected to the door 5 is attached to a reduction main shaft 26 protruding from the outer casing. [Effect] If the left and right rotating arms are separated from the door without entering moisture due to the closed casing, repair and inspection can be easily performed, and the appearance is also good.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic door controller.

[0002]

[Prior art]

 In general automatic door control, all the motors and reduction gears are installed around the door pillars, or they are all buried underground. The equipment to be installed around the stanchions is large in shape, requires a lot of labor to install, and impairs the overall appearance of the door. Those buried underground may damage the electric system due to infiltration of moisture or water, resulting in electrical leakage, and are not easily repairable.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to eliminate the drawbacks of the conventional control device, and to provide a controller that does not affect moisture and has a low failure rate.

[0004]

[Means for Solving the Problems]

 The means of the present invention are as follows.

A motor, a time controller therefor, and a speed reduction mechanism are installed in an outer casing, a left and right rotating arm is attached to a reduction main shaft protruding from the outer casing, and a top end is a pillar and a bottom end is supported by the reduction main shaft. An automatic door controller in which the protruding part and the left / right rotating arm are detachably fixed with screws.

[0006]

[Action]

 The rotation time of the motor is controlled by the time controller, and the rotation of the motor rotates the door through the speed reduction mechanism and the left / right rotation arm.

[0007]

Embodiment 1 In the figure, reference numeral 1 is an L-shaped outer casing in which a motor 3, a time controller 4, and a speed reduction mechanism 2 are mounted.

The speed reduction mechanism 2 includes a rotation shaft 23 having a bevel gear 21 meshing with a bevel gear 31 fixed to an output shaft 32 of a motor 3 and a worm 22, and a reduction main shaft 26 having a worm gear 25 meshing with the worm 22. The bearings 24 and 24 ′ that hold are the bearings of the rotary shaft 23. The deceleration main shaft 26 is projected vertically from the upper surface of the L-shaped outer casing 1 to fit a left / right rotating arm 61, and a tip end thereof is fitted into a bearing 62 in a case 63 mounted to a lower end of the door 5. A screw hole 611 is opened in the left / right rotating arm 61, a square piece 51 is fixed to the lower end of the door 5 by welding, a through hole 52 is provided in the square piece 51, and a screw 52 is passed through the through hole 52 to form a screw hole. When screwed into 611, the deceleration main shaft 26 and the left / right turning arm 61 turn the door 5.

The door 5 has a circular portion 50 integrally formed at a base portion and has recessed portions 70 and 71 formed at upper and lower ends thereof. A lower flange 66 of a door shaft 65 is fitted into the door portion 70, and the recessed portion 71 has the bearing case 63. And the door shaft 65 is inserted into the hole of the receiving plate 68 projecting from the column 8 to rotatably support the door 5.

The upper half 11 of the L-shaped outer casing 1 is attached to the side of the column 8. In the case of FIG. 5, the upper half 11 is put in a case 69 formed on the support column 8. The lower half 12 is embedded in the ground 7.

[0011]

【effect】

 According to the present invention, since the electric parts and the speed reduction mechanism are all enclosed and sealed in the outer casing, moisture does not enter, and the door can be easily removed by removing the screw 64 for repair and inspection inside the outer casing. All the necessary mechanisms are built into the outer casing and the appearance is good.
