There is. Item 1 is for household use and item 2 is for commercial use.

In normal use, it is desirable to simplify the operation as much as possible. In terms of installation, item 1 only requires connecting the push button switch and main unit 1 with two wires.
On the other hand, in the second term, a number of wires are required, leading to a reduction in connection reliability, sloppy operation, and high cost.

However, in item 1, if the button is stopped midway, it is unclear whether it will move upward or downward depending on the person or force of the next push button switch.

Samurai has the following operating directions: (1) If there are children in the direction of movement of the garage door and it must not be allowed to move, (2) If the garage door must be opened in an emergency due to a major accident, etc. When the garage door F is lowered by human power, it is not desirable for safety.To stop or reverse the garage door, you have no choice but to press the push button switch again. You will not be able to respond when needed.

The date and time of the present invention is that it is configured to accurately control multiple movements of a garage door. 1III.

The present invention connects the main body and the opening/closing command means with two wires, and by the on-one operation of the opening/closing command means, the operation command of the garage door is issued. The door is configured to repeat the operation at -C, and when the door begins to move, the on-state of the opening/closing command means stops. Focusing on the short turn-on operation,
When the time length of the ON operation is sufficient and is equal to or greater than J1, the garage door is automatically raised so that the garage door can be moved without using the opening/closing command means. .

The flip-flop 210 is set and the signal F is output. This commands all doors to rise, and the diode 308
A relay coil 240 for raising the door is excited by the transistor 237 through the transistor 237, the relay contact 242 is turned on, and the motor 16 is turned on. The motor is started in this way, but at the same time the signal BtdNOT element 221
The signal is input to the timer circuit 209 as a trigger signal. The purpose of this is to turn on the lamp 38r for a certain period of time after the operation command for illuminating the garage is given at the same time as the motor is started.The output of the timer circuit 209 excites the relay coil 239 by the transistor 236,

In this way, the motor 16 is stopped as before. Next, when further operation commands are given manually in the same way as the previous day, J-
Since the master-slave flip-flop 208 is set to , the output of the two-man AND element 226 is prohibited, and the signal B is output from the two-man power AND element 225, which sets the control flop 211 and outputs the signal Ga-. As a result, the transistor 238 is turned on, energizing the relay coil 241 for lowering the door, the relay crossing 42 is turned on, the motor 16 is reversed, and the door is lowered. When the lower limit switch 31 is turned on during the lowering operation, a signal H is output from the NOT element 219, and the integration circuit 2
12, a time delay T2 is provided, and the signal is input as a reset signal to the flip-flop 211 via the four-power N Oit element 230. This results in the upper limit O when ascending.
The motor stops as in the case of N. Next is failure qI! The entire circuit operation when the 27 detection limit switch 52 operates will now be explained.

The Noribu frog 211 is reset via the filter element 230. This will cause the simulator to stop and 111 under the door.
d production will also be stopped. Furthermore, when the pulse signal K falls,
The Q output of monostable multivibrator 207 rises,
The three-man power AND element 232 outputs a high (HiGH) υ signal. The signal is a differentiator circuit 213, NOT
It is converted into a signal M via the element i22, and is input to the two-man OR element 223. As a result, a series of control paths are followed as described above, and a signal F, which is a rising command, is output.
The door rises and is stopped by the signal from the upper limit switch 30, and by the output signal N from the NOT element 217. In this way, when the door detects an obstacle, the door immediately stops its operation while rising, immediately stops its lowering operation when it is descending, and starts raising again 13 hours later, demonstrating safe operation. However, is there a small obstacle (stone, stick, etc.) near the lower limit of the door?
When the lower limit switch 31 is turned on to prevent the p1 obstacle detection operation from being activated inadvertently due to the rise of the floor surface due to snow in winter, etc., the obstacle detection operation is immediately performed by the two-man NO sensor 231. Although prohibited, the signal G, which is a descending operation command, is set by the signal ■ after a time delay T2 by the integrating circuit 212. Furthermore, when the input of the obstacle Narita limit switch 52 is prohibited while the door is stopped, and when the above-mentioned go<, the obstruction operates and the door is stopped while the door is rising, the switch 52 is considered to be in the OFF state. Therefore, in order to start the door smoothly even under such conditions, two steps are required.
The output fall DY of the human-powered AND, that is, the door activation signal triggers the monostable multivibrator 250t-), and the output is human-powered by the three-person NAND element 251,
While this output is being output, the obstacle detection signal is ignored. Also, of course, ignoring the obstacle detection signal when the door is stopped will cause the output Y of the two-man power AND element 228 to become three-man power NANI)
This is achieved by manually controlling the NOT element 220 with respect to the element 251.

Next, the processing contents of the push button switch 12, which is the key point of the present invention, will be explained.

The output of the pushbutton switch 12 is a two-person NAND element 300.
F, Mf, S11. , the two-manpower NAND device 300
The operation based on the output signal is processed as described above. Furthermore, the output of the pushbutton switch 12 is output from the NoT element 301.
Trigger via monostable multivibrator 302ft. The monostable multi-nog ibrator 302 makes the output Q low (L OW ) for a certain period of time (approximately 2 seconds) through the set capacitor c52 and resistors R and 54. The output is connected to the two-person NANI) element 303, and the output of the NOT element 301 is further connected to the input terminal of the two-person Nki'JD element 303.

Therefore, the output of the two-man power NANI) element 303 becomes low (
LOW) level is reached when the Q output of the monostable multipipe rake 302 is at a high level 'E' D and the push button switch 12 is on. Tsumufu,
This means that it is confirmed that the push button switch 12 has been kept on for a certain period of time.

Ail Note 2 Manually Powered N A N D JAAs2 S3 output is connected to the resistor R, 3 of the reset circuit 205 via the buffer element 304 with a capacitor C53 inserted for noise absorption.
and connect to the midpoint of resistor R4.

Therefore, the NOT element 2180 (1, OW) level is zero! 21st road and 9th term, D
Clear to type noritsubu 70 horns 210, 211.

Further, the output of the buffer element 304 is connected to the A=s terminal of the monostable multivibrator 206, so that the monostable multivibrator 206 is not operated when the output of the buffer element 304 is at a low level. ing. At the same time, the output of the NFQ two-power NAND element 303 is connected to the two-man power NAND element 306 and the diode 30.
7, the transistor 237 is driven, the relay coil 240r is energized, and the door is fully raised. The rise is caused by NOT turning on the upper limit switch 30.
The output of element 305 becomes 7.i (High) level,
The output of the two-man power NOR element 306 is
jgj relevel and stop, or 13i
This is continued until the J push button switch 12 is turned off.

In particular, in this embodiment, the opening/closing command means is limited to the push button switch 12, and the manual input from the radio receiving device is omitted.

This is because by remote control, it is not possible to intuitively grasp the moving status of the garage door, and conversely, when trying to lower the garage door, it is expected that the garage door will stop midway, making it difficult to operate the garage door smoothly. I can't wait.

According to this embodiment, the total minimum distance between the push button switch and the main body is 2.
By simply connecting with a wire, you can repeat a predetermined operation or fully open the garage door in an emergency, improving both operability and safety.

In another embodiment, in FIG. 2, all D-type clip-flops are triggered by the output of the two-power NOR element 306, and the transistor 237 is driven by the output of the D-type seven clip-flop. Further, all the outputs of the NOT element 305 are connected to the clear terminal of the D type flip-frog, and the Q output of the D type 7 lip 70 is connected to the monostable multi-bi break 2060A terminal.

With this configuration, if the rhyming switch is on for a certain period of time or more, the garage door can be raised until the upper limit switch 30 is turned on even if the push ml switch is turned off.

During this operation, the A terminal of the monostable multivibrator 206 is at a low (LtJW) level, and no input is received from the radio receiver f or the push button switch 12.

According to the embodiment, the above-mentioned Act II! The same effect as column i can be obtained.

According to the present invention, the garage door operation can be accurately controlled with a minimum number of wires, ensuring safety and
Both operability and operability can be greatly improved.
