The monitoring shaft 321 for transmitting the rotational force of the tension line monitoring pulley 114 in the tension line driving unit 11 to the main controller 3 and the disc-shaped pulley perforated to allow light to pass through the disk at regular intervals ( The optical sensor 323 is installed with the 322 and the disk-shaped pulley 322 interposed therebetween, so that the on / off signal is repeatedly generated by the optical sensor 323 when the disk-shaped pulley 322 rotates. When the main controller 3 is engaged with the tension line driver 11, there is a locking plate 314 that can be inserted into the groove of the locking shaft 116 of the tension line driver 11 to fix the main controller 3.

As illustrated in FIG. 7, the control circuit board 33 has a wireless signal receiver 332 and a motor for receiving a signal to open, close, and stop from the microcomputer 331 and the remote controller 4. It consists of a motor driving circuit 333 to rotate, the tension line monitoring sensor receiver 334 and the power supply 335, the channel selection to select the channel of the power jack 336 and the wireless signal receiver 332 connected to the outside. It is comprised by the switch 337

The remote controller 4 is a wireless transmitter and uses a battery as a power source as a wireless transmitter that sends three signals of open, close and stop to the main controller 3.

As described above, the components of the present invention are composed of a main rail 1, an extension rail 2, a main controller 3, and a remote controller 4,

Combining the quantity and length of the main rail (1) and the extension rail (2) can satisfy the length of the various lengths of the curtain rail, and the length 6m of the curtain rail components as shown in Figure 1 Each component can be mounted on the 1.5m rail, allowing the unit length to be packed.

In the case of site installation, first fix the main rail (1) to the installation position and fix it to the ceiling by screwing the three rail fixing holes (25) on the rail using the screw (26), and then the left side of the extension rail (2). Fit the end to the position fixing plate 23 and the position fixing pin 22 located at the right end of the main rail 1, and then screw it into the rail fixing hole 25 to fix it to the ceiling.

When the position of the tension line driver 11 and the tension line tension retaining portion 14 is fixed, the tension in the tension line tension maintaining portion 14 is pulled by pulling the length adjusting tension line 151 in the pulling curtain 13. When the line pull pulley 141 is in the middle of the movable range and the knot 153 is formed, an appropriate tension is maintained on the tension line 15.

After the tension line tension adjustment is completed, the locking lever 314 of the main controller 3 is pulled to the right, and then the power transmission in the two locking shafts 116 at the bottom of the tension line driver 11 and the main controller 3 is performed. Mount the shaft 313 and the monitoring shaft 321 so that the lock lever 314 can be pushed in and fixed, and the power is connected to the power jack 336 at the bottom of the main controller 3 to complete the installation.

At the time of factory shipment, the channel selection switch 337 at the bottom of the main controller 3 is adjusted like the channel of the remote controller 4 so that the user can change the channel if necessary.

How it works

Upon receiving the open signal from the remote controller 4, the microcomputer 331 rotates the motor in the forward direction through the motor driving circuit 333. The rotational force of the motor rotates the tension wire guiding pulley 113 in the tension line driving unit 11 through the power transmission device 311, the power transmission gear 312, and the power transmission shaft 313. Since three meshed pulleys (111, 112, 113) are rotated at the same time to rotate the tension line 15

As the tension line 15 rotates, the curtain ring 13 fixed to the tension line 15 moves left and right to open the curtain.

At this time, the tension line monitoring pulley 114 in the tension line driver 11 is rotated by the frictional force with the tension line 15, the monitoring sensor 32 in the main controller 3 to generate an on / off signal. Therefore, the microcomputer 331 determines that the tension line 115 operates normally and waits for the on / off signal to be cut off.

When the curtain closes to the tension line driver 11 and the tension line tension holding unit 13 at the left and right ends of the rail, the tension line 15 is pulled from the tension line guiding pulleys 111, 112, 113 even if the motor rotates. When it is slipped, since the tension line 15 can no longer move, the tension line monitoring pulley 114 stops, and the microcomputer in the main controller 3 confirms that the on / off signal of the monitoring sensor 32 is broken. And stop the motor 31.

The curtain is closed in the same manner as in the case of opening, but if the curtain is caught during opening and closing, the tension line 15 cannot be rotated, so the microcomputer 331 of the main controller 3 stops the motor 31. Prevent overload of the motor

As above

In the present invention, it is easy to install and maintain by separating the rail and the main controller,

By using the position fixing plate and the position fixing pin on the rail to minimize the misalignment of the joints, the wheels of the curtains at the joints are smoothed, allowing the installation of multiple rails of unit length.

Tension wire drive part, curtain ring, and tension wire tension maintaining part are installed in one unit length rail with tension wire connected to improve convenience and handling of distribution process.

In particular, it provides prefabricated electric curtains that can be easily installed by anyone in the field and adjust the position and length of the curtains.
