In such an electric shielding device, a motor is arranged in the head box, the rotation of the output shaft of the motor is transmitted to the drive shaft, and the shielding material is raised and lowered based on the rotation of the drive shaft.

Further, an encoder for detecting the rotation speed and the amount of rotation of the drive shaft is arranged in the head box of the electric shielding device, and the speed and the number of pulses of the encoder pulse are counted based on the pulse signal output from the encoder. The value is controlled, and the rotation speed and the amount of rotation of the motor are controlled by a control device arranged in the head box. By such an operation, the speed of raising and lowering the shielding material is appropriately adjusted, and the stop position of the raised and lowered shielding material is controlled.

By the way, as a kind of electric shielding device, it is known that an electric pleated screen can be constructed by suspending a screen that can be folded vertically from the head box in a zigzag shape as a shielding material and allowing the screen to be electrically raised and lowered.

(overall structure)
1 (a) to 1 (c) are a plan view (downward view), a front view, and a side view showing a schematic configuration of an electric shielding device according to an embodiment of the present invention, respectively. As a typical example of the electric shielding device shown in FIG. 1, an electric pleated screen in which shielding materials are arranged in the front-rear direction and can be raised and lowered is shown. However, it is not necessary to limit each of the plurality of shielding materials arranged in the front-rear direction by the rotation of the drive shaft as long as they can be electrically raised and lowered.

As shown in FIG. 1 (c), the front screen 6F of this example is provided with a protruding piece 60 at the position of a crease on the outdoor side of the fabric to be bent in a zigzag shape, and the protruding piece 60 has a round hole or a length. An insertion hole formed of a hole or the like is provided, and an elevating cord 3F hanging from the head box 1 is inserted into the insertion hole. Therefore, the elevating cord 3F hangs down on the back side of the front screen 6F so that it cannot be visually recognized from the front as shown in FIG. 1B to enhance the aesthetic appearance. However, according to the present invention, an insertion hole may be provided in a substantially central portion of the front screen 6F in the front-rear direction so that the elevating cord 3F inserted through the insertion hole can be visually recognized from the front. Further, as shown in FIG. 1 (c), a pitch holding cord 4F is hung from the head box 1 behind the elevating cord 3F, and the lower end thereof is attached to the bottom rail 7F. A large number of annular support cords 40 are provided at equal intervals on the pitch holding cord 4F, and an elevating cord 3F is inserted through the support cord 40. Then, when the bottom rail 7F is lowered to extend the front screen 6F, the protruding pieces 60 are supported by the support cords 40 of the pitch holding cord 4F so that the folds of the front screen 6F are held at substantially equal intervals. It has become.

Further, a rear screen 6R that can be bent in a zigzag shape from the rear of the lower surface of the head box 1 is suspended and supported, and the lower end of the screen 6R is attached to the upper surface of the bottom rail 7R that functions as a weight member.

Similar to the front screen 6F, the rear screen 6R of this example is also provided with a projecting piece 60 at the position of the outdoor crease of the fabric to be bent in a zigzag shape, as shown in FIG. 1C, and the projecting piece 60 is provided. Each piece 60 is provided with an insertion hole formed of a round hole, an elongated hole, or the like, and an elevating cord 3R hanging from the head box 1 is inserted into the insertion hole. Therefore, the elevating cord 3R hangs down on the back side of the rear screen 6R so that it cannot be visually recognized from the front as shown in FIG. 1B to enhance the aesthetic appearance. However, according to the present invention, an insertion hole may be provided in a substantially central portion of the rear screen 6R in the front-rear direction so that the elevating cord 3R inserted through the insertion hole can be visually recognized from the front. Further, as shown in FIG. 1 (c), a pitch holding cord 4R is hung from the head box 1 behind the elevating cord 3R, and the lower end thereof is attached to the bottom rail 7R. A large number of annular support cords 40 are provided at equal intervals in the pitch holding cord 4R, and an elevating cord 3R is inserted through the support cord 40. Then, when the bottom rail 7R is lowered to extend the rear screen 6R, the protruding pieces 60 are supported by the support cords 40 of the pitch holding cords 4R, and the folds of the rear screen 6R are held at substantially equal intervals. It has become like.

The take-up drums 51F and 51R are arranged side by side in front of and behind each of the support members 5 arranged at appropriate positions (two locations on the left and right in this example) in the head box 1 and are rotatably supported. Cam clutches 52F and 52R are provided at one end in the axial direction of the winding drums 51F and 51R, respectively. Each take-up drum 51F and cam clutch 52F, and each take-up drum 51R and cam clutch 52R are configured to have the same shape.

The upper end of the elevating cord 3F (which is a string-shaped cord in this example, but may be a tape-shaped elevating tape) is attached to each winding drum 51F so that it can be wound or rewound. The lower end penetrates an insertion hole formed in each protruding piece 60 provided on the outdoor side of the front screen 6F, and is attached to the bottom rail 7F. The take-up drum 51F is formed so that the diameter gradually decreases in one direction in the axial direction, and in this example, the string-shaped elevating cord 3F is spirally wound around the take-up drum 51F. There is.

Further, the upper end of the elevating cord 3R (which is a string-shaped cord in this example, but may be a tape-shaped elevating tape) is attached to each winding drum 51R so that it can be wound or rewound, and the elevating cord is attached. The lower end of the 3R penetrates an insertion hole formed in each protruding piece 60 provided on the outdoor side of the rear screen 6R and is attached to the bottom rail 7R. The take-up drum 51R is formed so that the diameter gradually decreases in one direction in the axial direction. In this example, the string-shaped elevating cord 3R is spirally wound around the take-up drum 51R. There is.

A drive shaft 2F is inserted through the central shafts of the take-up drum 51F, the cam clutch 52F, and the rotary drum 53, and the rotary drum 53 transmits the rotation of the drive shaft 2F to the take-up drum 51F, and the take-up drum 51F The driving force is transmitted to the driving shaft 2F.

Similarly, a drive shaft 2R is inserted through the central shafts of the take-up drum 51R, the cam clutch 52R, and the rotary drum 53, and the rotary drum 53 transmits the rotation of the drive shaft 2R to the take-up drum 51R and takes up. The driving force of the drum 51R is transmitted to the driving shaft 2R.

One end of the drive shaft 2F is connected to the output shaft of the motor 9F via the drive shaft coupler 20F, and the rotation of the output shaft of the motor 9F is transmitted to the drive shaft 2F. Therefore, the bottom rail 7F can be raised and lowered by rotating the drive shaft 2F with the driving force of the motor 9F and winding or rewinding the elevating cord 3F with the take-up drum 51F based on the rotation of the drive shaft 2F. As a result, the front screen 6F can be raised and lowered. Since the take-up drum 51F uses the tension related to the elevating cord 3F (the own weight of the front screen 6F and the bottom rail 7F) when the front screen 6F is lowered, its driving force is taken up via the rotary drum 53. It is transmitted from the drum 51F to the drive shaft 2F, and the driving force related to the drive shaft 2F is adjusted to control the descent.

Further, one end of the drive shaft 2R is connected to the output shaft of the motor 9R via the drive shaft coupler 20R, and the rotation of the output shaft of the motor 9R is transmitted to the drive shaft 2R. Therefore, the bottom rail 7R can be raised and lowered by rotating the drive shaft 2R with the driving force of the motor 9R and winding or rewinding the elevating cord 3R with the take-up drum 51R based on the rotation of the drive shaft 2R. As a result, the rear screen 6R can be raised and lowered. Since the take-up drum 51R uses the tension related to the elevating cord 3R (the own weight of the rear screen 6R and the bottom rail 7R) when the rear screen 6R is lowered, its driving force is transmitted via the rotating drum 53. It is transmitted from the take-up drum 51R to the drive shaft 2R, and the driving force related to the drive shaft 2R is adjusted to control the descent.

The drive control of each of the motors 9F and 9R is performed by the control device 10 arranged in the head box 1. A DC power supply 11 for supplying electric power to the motors 9F and 9R and the control device 10 is arranged in the head box 1. When the control device 10 receives an operation signal (not shown) from an external device (not shown) such as a wired switch 21, an infrared remote controller 22, a wireless remote controller 23, or a personal computer (PC), the control device 10 executes various commands included in the operation signal. Performs various controls for the corresponding electric shielding device. For example, by configuring the motors 9F and 9R with DC motors, respectively, by controlling the duty ratio of the pulse signals supplied from the control device 10 to the motors 9F and 9R, the control device 10 controls the rotation speeds of the motors 9F and 9R. Can be controlled. Further, encoders 8F and 8R for detecting the rotation speeds and rotation amounts of the drive shafts 2F and 2R are arranged in the head box 1, and the control device 10 uses the pulse signals output from the encoders 8F and 8R. Based on this, the speed of the encoder pulse and the count value of the number of pulses are managed to control the rotation speed and the amount of rotation of the motors 9F and 9R. By such an operation, the control device 10 appropriately adjusts the ascending / descending speed of the front screen 6F or the rear screen 6R in response to various commands included in the operation signal, and also adjusts the ascending / descending speed of the front screen 6F or the front screen 6F. The ascending / descending stop position of the rear screen 6R is controlled.

In the electric pleated screen of the present embodiment configured as described above, for example, the bottom rail 7F is pulled up to just below the head box 1, and the front screen 6F is folded between the head box 1 and the bottom rail 7F. When the bottom rail 7R is lowered, the rear screen 6R is shielded from the head box 1 to a desired position.

Further, when the bottom rail 7F is lowered, the front screen 6F is shielded from the head box 1 to a desired position. Therefore, for example, if the rear screen 6R is used as a daylighting cloth and the front screen 6F is used as a light-shielding cloth, the degree of freedom in adjusting the amount of daylighting can be increased. When the bottom rail 7R is pulled up to the upper limit and opened, the rear screen 6R can be folded between the head box 1 and the bottom rail 7R.

(Clutch type obstacle detection and stopping device)
By the way, when the bottom rail 7F or the bottom rail 7R comes into contact with an obstacle and its lowering is hindered, the clutch-type obstacle detection / stopping device is activated to lock the drive shaft 2F or 2R. That is, when the bottom rail 7F or the bottom rail 7R comes into contact with an obstacle, the take-up drum 51F and the cam clutch 52F supported by the support member 5, and the take-up drum 51R and the cam clutch 52R are the bottom rails 7F, respectively. It functions as a clutch-type obstacle detection / stopping device that mechanically performs "obstacle detection" for 7R and "stop" of each drive shaft. That is, the take-up drum 51F and the cam clutch 52F supported by the support member 5, and the take-up drum 51R and the cam clutch 52R are configured as a clutch-type obstacle detection / stopping device as shown in FIG.
Hereinafter, the clutch-type obstacle detection / stopping device will be briefly described.

Since the take-up drum 51R and the cam clutch 52R have the same structures as the take-up drum 51F and the cam clutch 52F, respectively, they are typically supported by the support member 5 in FIG. 2A. A cross-sectional view of the configuration of the take-up drum 51F and the cam clutch 52F that function as a clutch-type obstacle detection / stopping device is shown.

As shown in FIG. 2A, in the clutch-type obstacle detection / stopping device, the take-up drum 51F and the cam clutch 52F are supported by the support portion 50 in the support member 5, and the cam clutch 52F uses the rotating drum 53. It is connected to the take-up drum 51F via.

The cam clutch 52F, the rotary drum 53, and the take-up drum 51F are rotatably supported between the through holes 502 and 503 formed at both the left and right ends of the support portion 50. More specifically, the tubular portion 521 of the cam clutch 52F is rotatably supported by the through hole 502, and the pulley cap 54 fitted to the right end of the take-up drum 51F is rotatable with respect to the through hole 503. It is pivotally supported.

The rotary drum 53 is housed inside the cam clutch 52F in the radial direction, and the rotary drum 53 has a substantially cylindrical shape, has a predetermined rotational play with respect to the take-up drum 51F, cannot rotate relative to the winding drum 51F, and does not move relative to the axial direction. It is installed like this. Further, although the drive shaft 2F penetrates the tubular portion 521 so as to be relatively rotatable, the rotating drum 53 rotates integrally with the drive shaft 2F.

The snap-fit 501 is formed with a take-out port for winding or rewinding the elevating cord 3F from a predetermined position. Further, a braking convex portion 504 is formed on the bottom surface of the left side of the support portion 50 in the drawing.

The take-up drum 51F is formed in a substantially cylindrical shape, and includes an engaging portion 511 and a take-up portion 512.

The winding portion 512 of the winding drum 51F is set so that its diameter gradually decreases from the cam clutch 52F side toward the right end side in the drawing. The drive shaft 2F is rotatably penetrated through the center of the pulley cap 54 fitted to the right end of the take-up drum 51F in the drawing.

A cam clutch 52F is housed inside the engaging portion 511 of the take-up drum 51F in the radial direction. The cam clutch 52F includes a tubular portion 521 formed in a substantially cylindrical shape and a braking portion 522 formed having a diameter larger than that of the tubular portion 521.

The diameter of the outer peripheral surface of the braking portion 522 is set to a size that allows it to slide with the inner peripheral surface of the engaging portion 511 of the take-up drum 51F. One or a plurality of braking claws 523 are formed so as to project in a sawtooth shape at the end of the braking portion 522 on the tubular portion 521 side, and can be engaged with the braking convex portion 504 of the support portion 50.

When the braking claw 523 is prevented from rotating in the circumferential direction by engaging with the braking convex portion 504, the cam clutch 52F is made unable to rotate relative to the support portion 50.

In the cam clutch 52F, the side wall of the braking portion 522 is assembled via the rotary drum 53 so as to be non-rotatable relative to the take-up drum 51F with a predetermined rotational play, and the axis line is within the range of the predetermined rotational play. It has a cam structure that allows relative movement (sliding) along the direction.

That is, a sliding hole 524 as a cam structure is formed on the side wall of the braking portion 522 in the cam clutch 52F, and the sliding hole 524 is formed so as to be inclined by approximately 45 ° with respect to the axis of the braking portion 522. ing. Further, the length of the sliding hole 524 is set so as to be arranged over an angle range of approximately 45 ° in the circumferential direction of the braking portion 522.

The rotating drum 53 is formed with a sliding convex portion 531 that projects outward in the radial direction. The rotating drum 53 is assembled to the cam clutch 52F so that the sliding convex portion 531 is located inside the sliding hole 524 of the cam clutch 52F. Relative movement is possible only within the range of relative movement inside.

Specifically, when the sliding convex portion 531 is located at one end of the sliding hole 524, the cam clutch 52F is most axially accommodated with respect to the take-up drum 51F (right side in FIG. 2A). Since it is located at, the engagement state between the braking claw 523 and the braking convex portion 504 is released. On the other hand, when the sliding convex portion 531 is located at the other end of the sliding hole 524, the cam clutch 52F slides in the axial direction and protrudes most axially with respect to the take-up drum 51F (FIG. Since it is located on the left side in 2 (a), the braking claw 523 and the braking convex portion 504 are in an engaged state.

When the braking claw 523 and the braking convex portion 504 are engaged with each other, the rotation of the cam clutch 52F is blocked, and the moving range of the cam clutch 52F is restricted by the engaging range of the rotating drum 53 and the take-up drum 51F. The rotation of the rotary drum 53 is stopped in a state where the sliding convex portion 531 is moved to the other end of the sliding hole 524, and the rotation of the drive shaft 2F which is connected to the rotary drum 53 so as to be relatively non-rotatable is also stopped.

Therefore, when the cam clutch 52F moves relative to the take-up drum 51F in the axial direction and the braking claw 523 is engaged with the braking convex portion 504, the cam clutch 52F is locked so as not to rotate relative to the support portion 50. NS. Further, when the engagement state between the braking claw 523 and the braking convex portion 504 is released, the cam clutch 52F can rotate relative to the support portion 50.

In this way, when the drive shaft 2F is rotated in the pulling direction of the shielding material (front screen 6F), the rotation is transmitted to the rotating drum 53. At this time, the rotary drum 53 is rotated relative to the take-up drum 51F and the cam clutch 52F during the predetermined rotational play.

In this case, the engagement state between the braking claw 523 of the cam clutch 52F and the braking convex portion 504 of the support portion 50 is released, and the cam clutch 52F can rotate relative to the support portion 50. Then, the rotary drum 53 becomes unable to rotate relative to the cam clutch 52F and the take-up drum 51F when the rotation is equal to or greater than the predetermined rotation play.

Therefore, when the drive shaft 2F is further rotated in the pulling direction, the rotating drum 53 is integrally rotated in the pulling direction together with the cam clutch 52F and the take-up drum 51F, and the shielding material (front screen 6F) is pulled up. It is said.

On the other hand, when the drive shaft 2F pulls down the shielding material (front screen 6F), the weight of the front screen 6F and the bottom rail 7F is used for pulling down, so that the driving force at the time of pulling down is from the take-up drum 51F to the drive shaft 2F. It is transmitted toward.

When the take-up drum 51F and the cam clutch 52F are rotated in the pulling direction, the engagement state between the braking claw 523 of the cam clutch 52F and the braking convex portion 504 of the support portion 50 is released, so that the rotating drum 53 And the drive shaft 2F is immediately transmitted to rotate in the pulling direction.

Here, FIGS. 2 (b) to 2 (e) show FIG. 2 (a) when the bottom rail 7F collides with an obstacle while the shielding material (front screen 6F) is being pulled down. ), The operation of the take-up drum 51F and the cam clutch 52F that function as a clutch-type obstacle detection / stopping device is shown in a schematic diagram. Although a simplified diagram is shown as one braking claw 523 in FIGS. 2D and 2E, a plurality of braking claws 523 can be used.

First, as shown in FIG. 2B, when the shielding material (front screen 6F) is being pulled down, the elevating cord 3F is wound from the take-up drum 51F before the bottom rail 7F collides with an obstacle. It is returned and the front screen 6F is lowered. Tension in the pull-out direction is applied to the elevating cord 3F wound around the take-up drum 51F due to the weight of the bottom rail 7F, etc., and the take-up drum 51F rotates by its own weight as the cam clutch 52F rotates, and the drive shaft 2F The rotation control controls the rotation of its own weight. At this time, the sliding convex portion 531 is located at one end of the sliding hole 524, and the cam clutch 52F is located on the side (right side in FIG. 2A) that is most accommodated in the axial direction with respect to the take-up drum 51F. Therefore, the engagement state between the braking claw 523 and the braking convex portion 504 is released.

Then, as shown in FIG. 2C, when the bottom rail 7F collides with an obstacle, the tension in the pull-out direction in the elevating cord 3F is lost, and the rotation of the take-up drum 51F and the cam clutch 52F is stopped, but the rotating drum 53 , And the drive shaft 2F maintains the rotation, so that a rotation difference occurs. However, the rotating drum 53 is rotated relative to the take-up drum 51F only during the predetermined rotation play.

Then, the sliding convex portion 531 is guided to the sliding hole 524, and as shown in FIG. 2D, during the course of the predetermined rotation play of the rotating drum 53 as the winding drum 51F stops rotating, the sliding convex portion 531 is guided to the sliding hole 524. The cam clutch 52F starts relative movement (slide) in the axial direction.

Then, as shown in FIG. 2E, the braking claw 523 in the cam clutch 52F engages with the braking convex portion 504 during the lapse of the predetermined rotational play of the rotating drum 53 as the rotation of the winding drum 51F is stopped. By doing so, rotation in the circumferential direction is prevented, and the cam clutch 52F cannot rotate relative to the support portion 50. The rotation of the cam clutch 52F is blocked, and at this time, the moving range of the cam clutch 52F is restricted by the engaging range of the rotating drum 53 and the take-up drum 51F. The rotation of the rotary drum 53 is stopped while the 531 is moved, and the rotation of the drive shaft 2F which is connected to the rotary drum 53 so as to be relatively non-rotatable is also stopped. In this way, the cam clutch 52F is made unable to rotate relative to the support portion 50, and when the predetermined rotational play of the rotating drum 53 elapses, the rotation of the rotating drum 53 also stops, and the rotation of the drive shaft 2F is locked.

In the example shown in FIG. 2, in the cam clutch 52F, the side wall of the braking portion 522 is assembled to the take-up drum 51F via the rotating drum 53 so as to be unable to rotate relative to the winding drum 51F, and the predetermined rotation. Within the range of play, the sliding hole 524 formed in the cam clutch 52F guides the sliding convex portion 531 formed in the rotating drum 53, so that the cam structure can be relatively moved (sliding) along the axial direction. However, the cam structure that mechanically locks the drive shaft 2F is not limited to this example, and the rotation of the drive shaft 2F is mechanically rotated when the rotation of the take-up drum 51F is stopped due to a physical obstacle. Various forms are conceivable, as long as the cam clutch structure is used to stop the vehicle.

For example, instead of the rotating drum 53 and the cam clutch 52F, a cam clutch having a braking claw 523 that can engage with the braking convex portion 504 and a sliding convex portion 531 is formed, and the cam clutch is included in the take-up drum 51F. It can be configured to be supported by a peripheral wall. In this case, the cam clutch has a structure that cannot rotate relative to the drive shaft 2F but allows relative movement (slide movement) within a predetermined range with respect to the take-up drum 51F in the axial direction, and the sliding convex In order to operate the rotation of the portion 531 in the same manner as the operation illustrated in FIG. 2, a cam clutch structure in which a sliding groove corresponding to the sliding hole 524 is formed on the inner peripheral wall of the take-up drum 51F can be formed.

(Operating device)
FIG. 4 is a diagram showing a schematic configuration of an infrared remote controller 22 typical as an operating device of an embodiment in the electric shielding device of the embodiment according to the present invention. The infrared remote controller 22 of this embodiment has only one set of open / close buttons (open button 221 and close button 222) and a stop button 223, and the same applies to the wired switch 21 and the wireless remote controller 23 shown in FIG.

The infrared remote controller 22 shown in FIG. 4 is divided into groups according to device IDs up to a maximum of 4 groups when a plurality of electric shielding devices are installed as operation targets, and a plurality of electric remote controllers having the same device ID are used. Regarding the shielding device, a group designation button (circle button of "1" to "4" in the figure) 224 for group designation and simultaneous operation, and a batch designation button for simultaneous operation of all groups (shown in the figure). It has an "ALL" button) 225. Device IDs corresponding to the group designation button 224 and the batch designation button 225 can be set for each of the plurality of electric shielding devices installed as operation targets by a DIP switch or the like. Therefore, normally, when the infrared remote controller 22 shown in FIG. 4 is used, the control device 10 in the electric shielding device to be operated is an open / close button (open button 221) transmitted after pressing the group designation button 224 or the batch designation button 225. And the operation signal by pressing the close button 222) and the stop button 223 are recognized and controlled to perform the corresponding operation. However, the set value of the device ID in each electric shielding device does not require pressing the group designation button 224 or the batch designation button 225, and the open / close button (open button 221 and close button 222) and the stop button 223 are directly pressed. It is possible to provide a mode for recognizing the operation signal due to pressing and controlling so as to perform the corresponding operation.

Then, as described above, the infrared remote controller 22 shown in FIG. 4 has a function of transmitting an operation signal by infrared rays to the control device 10 in the electric shielding device to be operated, and opens the button when performing the ascending operation. The ascending command can be transmitted by pressing 221, the descending command can be transmitted by pressing the close button 222 when performing the descending operation, and the stop command can be transmitted by pressing the stop button 223 when performing the stopping operation of the ascending / descending operation.

Further, when the operation device such as the infrared remote controller 22 sets the upper and lower limit positions of the shielding materials, the stop button 223 is pressed and held for a predetermined time, or the open button 221 and the stop button 223 are simultaneously held and held for a predetermined time. , The setting command for shifting to the setting mode can be transmitted to the control device 10 in the electric shielding device to be set. After shifting to the setting mode based on the reception of the setting command, the control device 10 in the electric shielding device to be set automatically raises one of the predetermined shielding materials among the plurality of shielding materials possessed by the electric shielding device to be set. Then, the upper limit position is set by pressing and holding the stop button 223 for a predetermined time and stored in the storage unit 102, and then the other shielding material is automatically raised, and the upper limit position is determined by pressing and holding the stop button 223 for a predetermined time. Is determined and stored in the storage unit 102, then each shielding material is automatically lowered, and the lower limit position setting of each shielding material is determined by pressing and holding the stop button 223 for a predetermined time and stored in the storage unit 102.

There is no physical detection switch to detect. Even in this case, the control device 10 determines the absolute upper and lower limit positions based on the count value of the encoder pulse obtained from the encoders 8F and 8R, or the abnormality detection unit 108F and 108R causes an abnormality in the motor drive units 107F and 107R. By detecting each value (1 or more of overcurrent / abnormal waveform current / abnormal waveform voltage), or detecting that the input of the encoder pulse for a predetermined time disappears during operation control, etc. , The physical upper limit position and the physical lower limit position that define the physical elevating operation range can be detected for each of the front side screen 6F and the rear side screen 6R. The physical upper limit position and the physical lower limit position may be set as the movable range, or the upper limit position and the lower limit position may be set to the operator's desired position by the setting by the above-mentioned operating device, and the set upper limit position and the set lower limit position may be set as the movable range. May be good.

By the way, the control device 10 in the electric shielding device of the present embodiment shown in FIGS. 1 and 3 is derived from the operation device based on the pressing of a set of open / close button and stop button in the operation device such as the infrared remote controller 22 shown in FIG. Depending on whether or not the operation signals related to ascending / descending are continuously received among the receivable ascending / descending and stopping operation signals, individual elevating control of the front side shielding material and the rear side shielding material, and the front side shielding material and the rear side shielding material are performed. The simultaneous ascending / descending control and the ascending / descending control are selectively performed. That is, it is not necessary to provide an elevating operation button on the operation device for the front side shielding material (front side screen 6F) and the rear side shielding material (rear side screen 6R), and each of the plurality of shielding materials can be moved up and down at the same time by electric power. The usability has been improved by controlling it so that it can be operated.

Hereinafter, taking the operation by the infrared remote controller 22 as an example, as the ascending / descending control of each of the plurality of shielding materials arranged in the front-rear direction by the control device 10 of the electric shielding device to be operated, "same direction descending control" and "same direction". "Direction ascending control" and "Different direction ascending / descending control" will be described in order.

(Same direction descent control)
FIG. 5 is a flowchart showing an example of in the same direction lowering control of each of a plurality of shielding materials by the control device 10 in the electric shielding device of one embodiment according to the present invention, and FIGS. 6 (a) to 6 (c) are the same. It is a schematic diagram for demonstrating the operation of the electric shielding device at the time of the same-direction descent control of each of a plurality of shielding materials by a control device 10.

First, the control device 10 is lowered by the first pressing of the close button 222 as shown in FIG. 6A while the operation of the front shielding material (front screen 6F) and the rear shielding material (rear screen 6R) is stopped. When the command is received (step S11), one of the front shielding material (front screen 6F) and the rear shielding material (rear screen 6R) is predetermined (in this example, the rear shielding material, the bottom). Only the rear screen 6R) having the rail 7R at the lower end starts the lowering operation (step S12).

Under the lowering operation of the rear shielding material, the control device 10 monitors whether or not a further lowering command has been received (step S13).

During the lowering operation of the rear shielding material (rear screen 6R), the control device 10 further lowers by pressing the close button 222 a second time as shown in FIG. 6B prior to receiving the stop command. When a command is received (step S13: Y), the other predetermined shielding material (in this example, the front screen 6F having the bottom rail 7F at the lower end) is also started to descend at the same time. (Step S14). On the other hand, the control device 10 monitors the reception of the stop command (step S17: N) when the lowering command is not received during the lowering operation of the rear shielding material (rear screen 6R) (step S13: N). ), When the stop command is received prior to the reception of the descending command (step S17: Y), the descending operation of the rear shielding material (rear screen 6R) is stopped (step S18), and this control is terminated. ..

When the rear shielding material (rear screen 6R) during the descending operation reaches the lower limit position, the control device 10 lowers the rear shielding material (rear screen 6R) before receiving the stop command. The operation is automatically stopped, and similarly, when the front shielding material (front screen 6F) during the descending operation reaches the lower limit position, the descending operation of the front shielding material (front screen 6F) is automatically stopped.

The control device 10 has a stop command during the lowering operation of only the rear shielding material (rear screen 6R) or during the lowering operation of both the rear shielding material (rear screen 6R) and the front shielding material (front screen 6F). (Step S15: N).

Then, the control device 10 is in the lowering operation of only the rear shielding material (rear screen 6R), or during the lowering operation of both the rear shielding material (rear screen 6R) and the front shielding material (front screen 6F). When a stop command is received by pressing the stop button 223 as shown in FIG. 6 (c) (step S15: Y), the lowering operation of all the shielding materials is stopped, and this control is terminated (step S16).

As described above, the control device 10 is an operation signal related to ascending / descending among the ascending / descending and stopping operation signals that can be received from the operating device based on the pressing of a set of the close button and the stop button in the operating device such as the infrared remote controller 22. Depending on whether or not the reception is continuous, the elevating control of the front side shielding material and the rear side shielding material and the simultaneous elevating control of the front side shielding material and the rear side shielding material are selectively performed. There is. For this reason, a simple operation of a set of a close button and a stop button allows the lowering motions of the plurality of shielding materials arranged in the front and rear to be set to their respective desired stop positions, and individually. Not only when it is done, but it is also possible to do it at the same time, which improves usability.

(Same direction ascent control)
FIG. 7 is a flowchart showing an example of in the same direction ascending control of each of the plurality of shielding materials by the control device 10 in the electric shielding device according to the present invention, and FIGS. 8 (a) to 8 (c) are the same. It is a schematic diagram for demonstrating the operation of the electric shielding device at the time of the same-direction rise control of each of a plurality of shielding materials by a control device 10.

First, the control device 10 is raised by the first pressing of the open button 221 as shown in FIG. 8A while the operation of the front shielding material (front screen 6F) and the rear shielding material (rear screen 6R) is stopped. Upon receiving the command (step S21), one of the front shielding material (front screen 6F) and the rear shielding material (rear screen 6R) is predetermined (in this example, the front shielding material, the bottom rail). Only the front screen 6F) having 7F at the lower end starts the ascending operation (step S22).

Under the ascending operation of the front shielding material, the control device 10 monitors whether or not a further ascending command has been received (step S23).

During the ascending operation of the front shielding material (front screen 6F), the control device 10 issues a further ascending command by pressing the open button 221 a second time as shown in FIG. 8B prior to receiving the stop command. Upon reception (step S23: Y), the other predetermined shielding material (in this example, the rear screen 6R having the bottom rail 7R at the lower end) also starts the ascending operation at the same time. (Step S24). On the other hand, the control device 10 monitors the reception of the stop command (step S27: N) when the ascending command is not received during the ascending operation of the front shielding material (front screen 6F). When the stop command is received prior to the reception of the ascending command (step S27: Y), the ascending operation of the front shielding material (front screen 6F) is stopped (step S28), and this control is terminated.

When the front shielding material (front screen 6F) during the ascending operation reaches the upper limit position prior to receiving the stop command, the control device 10 automatically ascends the front shielding material (front screen 6F). Similarly, when the rear shielding material (rear screen 6R) during the ascending operation reaches the upper limit position, the ascending operation of the rear shielding material (rear screen 6R) is automatically stopped.

The control device 10 receives a stop command during the ascending operation of only the front shielding material (front screen 6F) or during the ascending operation of both the front shielding material (front screen 6F) and the rear shielding material (rear screen 6R). (Step S25: N).

Then, the control device 10 is in the ascending operation of only the front side shielding material (front side screen 6F), or during the ascending operation of both the front side shielding material (front side screen 6F) and the rear side shielding material (rear side screen 6R), FIG. When a stop command is received by pressing the stop button 223 as shown in (c) (step S25: Y), the ascending operation of all the shielding materials is stopped, and this control is terminated (step S26).

As described above, the control device 10 is an operation signal related to ascending / descending among the ascending / descending and stopping operation signals that can be received from the operating device based on the pressing of a set of open and stop buttons in the operating device such as the infrared remote controller 22. Depending on whether or not the reception is continuous, each of the plurality of shielding materials arranged in the front and rear is electrically controlled so as to be able to be raised at the same time. Therefore, by a simple operation of a set of open button and stop button, each of the plurality of shielding materials arranged in the front-rear direction can be raised at the same time while being allowed to be set to their desired stop positions. It will be possible and the usability will be improved.

In the same-direction elevating control (same-direction descent control and same-direction ascending control) shown in FIGS. 5 to 8 described above, the control device 10 receives a "second descent command" after receiving the "first descent command". It is possible to control so that only the "stop command" is allowed and the reception of the "ascending command" is not allowed. Similarly, after receiving the "first ascending command", the "second ascending command" and the "stop" are allowed. The control can be such that only the "command" is allowed and the reception of the "downward command" is not allowed. However, the control device 10 allows the reception of the "ascending command" even after receiving the "first descending command", or allows the reception of the "descending command" even after receiving the "first descending command". Usability may be improved even when "different direction elevating control" is provided. For example, by receiving the "first ascending command" to raise the front shielding material and at the same time lowering the rear shielding material by receiving the subsequent "descending command", for example, the front shielding material is reared to the upper limit position. As for the side shielding material, it is sufficient to press the open button and the close button twice up to the lower limit position. In addition, all of the shielding materials in operation can be stopped immediately by pressing the stop button once.
Hereinafter, this "different direction elevating control" will be described with reference to FIGS. 9 and 10.

(Different direction lift control)
FIG. 9 is a flowchart showing an example of control of raising and lowering each of the plurality of shielding materials by the control device 10 in the electric shielding device according to the present invention in different directions, and FIGS. 10 (a) to 10 (c) are the same. It is the schematic for demonstrating the operation of the electric shielding device at the time of each different direction elevating control of a plurality of shielding materials by a control device 10. Here, an example of "different direction elevating control" that allows reception of the "descending command" even after receiving the "first ascending command" will be described as a representative.

First, the control device 10 receives an ascending command by pressing the open button 221 as shown in FIG. 10A while the operation of the front shielding material (front screen 6F) and the rear shielding material (rear screen 6R) is stopped. Then (step S31), one of the predetermined shielding material (in this example, the front shielding material, the bottom rail 7F) of the front shielding material (front screen 6F) and the rear shielding material (rear screen 6R) is placed at the lower end. The ascending operation is started only on the front screen 6F) held in (step S32).

Under the ascending operation of the front shielding material, the control device 10 monitors whether or not a descending command is received (step S33). It should be noted that the operation when the control device 10 receives the second ascending command under the ascending operation of the front shielding material is the same-direction ascending control shown in FIGS. 7 and 8 described above, and the description of the operation is omitted. do.

When the control device 10 receives the descending command by pressing the close button 222 as shown in FIG. 10B prior to receiving the stop command during the ascending operation of the front shielding material (front screen 6F) ( Step S33: Y), the ascending operation of the front shielding material (front screen 6F) is stopped (step S34), and the process proceeds to step S12 shown in FIG. Further, the control device 10 proceeds to step S23 shown in FIG. 7 when the lowering command is not received during the ascending operation of the front shielding material (front screen 6F) (step S33: N).

In FIGS. 9 and 10, the control device 10 has been described as a representative example of the “different direction ascending / descending control” in which the control device 10 allows the reception of the “descending / descending command” even after receiving the “first ascending command”. The same applies to the "different direction ascending / descending control" that allows the reception of the "ascending command" even after receiving the "descending command", and the description thereof will be omitted. As an application of these elevating controls, the control device 10 is operated by operating an open / close button in the opposite direction received during elevating control in one direction (for example, ascending) of one or both of the shielding materials. Depending on the reception of the signal, the other or both shielding materials may be controlled to move up and down in the direction opposite to the operating direction in the one direction (for example, descending).

As described above, the control device 10 is an operation signal related to ascending / descending among the ascending / descending and stopping operation signals that can be received from the operating device based on the pressing of a set of open / close buttons and the stop button in the operating device such as the infrared remote controller 22. Depending on whether or not the reception is continuous, each of the plurality of shielding materials arranged in the front and rear can be electrically controlled so as to be simultaneously raised and lowered. Therefore, by a simple operation of a set of open / close buttons and a stop button, each of the plurality of shielding materials arranged in the front-rear direction can be raised and lowered at the same time while being allowed to be set to their desired stop positions. It will be possible and the usability will be improved.

For example, the electric shielding device is not limited to the electric pleated screen described above, but has a roll screen, a raised curtain, or a hybrid configuration in which these different types of shielding materials are arranged in the front-rear direction (for example, the front shielding material has a hybrid configuration). It can also be applied to other types of electric shielding devices such as a raised curtain type shielding material and a pleated screen type shielding material for the rear shielding material).

Typical examples of other electric shielding devices having shielding materials in the front and rear are shown in FIGS. 11A and 11B, respectively. 11 (a) and 11 (b) are schematic side views showing an example in which the control device 10 according to the present invention is applied to the electric shielding device of another typical embodiment according to the present invention, respectively.

First, the electric shielding device shown in FIG. 11A has a front shielding material (front screen 6F provided with a weight bar 7F'which functions as a weight member at the lower end) and a rear shielding material (functioning as a weight member at the lower end). This is an electric roll screen that allows the rear screen 6R) provided with the weight bar 7R'to be raised and lowered at the same time. The take-up pipes 51F'and 51R'shown in FIG. 11A are functional parts that raise and lower the front screen 6F and the rear screen 6R by winding or rewinding them, respectively, and the encoders 8F and 8R and the encoders 8F and 8R are respectively inside. Motors 9F and 9R are arranged (not shown). The take-up pipes 51F'and 51R' are rotatably supported between the support members 1a supported on both the left and right sides of the mounting frame 1'. Then, a DC power supply 11 (not shown) and a control device 10 similar to that shown in FIG. 3 are arranged in the mounting frame 1'. Therefore, with respect to the electric roll screen shown in FIG. 11A, a plurality of control devices 10 are arranged in the front-rear direction by "same direction lowering control", "same direction ascending control", and "different direction raising / lowering control". Each of the step-shielding materials can be electrically controlled so that they can be raised and lowered at the same time, which improves usability.

Further, the electric shielding device shown in FIG. 11B is an electric raised curtain that allows the front shielding material (front curtain fabric 6F') and the rear shielding material (rear curtain fabric 6R') to be raised and lowered at the same time. .. The front side shielding material (front side curtain cloth 6F') is suspended and supported from the front surface of the head box 1 shown in FIG. The rear curtain fabric 6R') is suspended and supported. A ring 80 is attached to the center of the front side shielding material (front side curtain cloth 6F') and the rear side shielding material (rear side curtain cloth 6R') in the vertical direction near both sides in the width direction, and the ring 80 is attached to the ring 80. Elevating cords 3F and 3R are inserted, respectively. In this example, a hook type cord catch 30 is attached to the lower ends of the elevating cords 3F and 3R, and the hook receiving portion 31 for hanging each cord catch 30 is a front shielding material (front curtain fabric 6F') and a rear. It is attached to each lower end of the side shielding material (rear side curtain cloth 6R'). The take-up drums 51F and 51R shown in FIG. 11B are suspended and supported from the head box 1 by winding or rewinding the upper ends of the elevating cords 3F and 3R, respectively, as in the embodiment shown in FIG. The front shielding material (front curtain fabric 6F') and the rear shielding material (rear curtain fabric 6R') are raised and lowered. Encoders 8F and 8R and motors 9F and 9R are arranged in the head box 1, respectively (not shown). Then, a DC power supply 11 (not shown) and a control device 10 similar to that shown in FIG. 3 are arranged in the head box 1. Therefore, also for the electric tucking curtain shown in FIG. 11B, the control device 10 is arranged in the front-rear direction by "same direction lowering control", "same direction ascending control", and "different direction raising / lowering control". Each of the plurality of stages of the shielding material can be electrically controlled so that it can be raised and lowered at the same time, which improves usability.

The control device 10 of the electric shielding device illustrated in FIGS. 1 and 11 described above is designed to electrically control each of the plurality of shielding materials arranged in the front-rear direction so as to be able to move up and down. As a command related to the opening / closing operation of the shielding material without requiring an individual command for identifying the material, an ascending command (also collectively referred to as an "opening command" because it is a command for opening an operation for various shielding materials), The ascending / descending operation is electrically possible by the descending command (generally referred to as the "closing command" because it is a command of the closing operation chain for various shielding materials) and the operation signal having only one set of the stop command.

Then, it is possible to construct a remote control system for remotely controlling the electric shielding device illustrated in FIGS. 1 and 11 via an Internet-based network using a smart speaker or a mobile terminal such as a smartphone.

[Remote control system]
Hereinafter, an example of a remote control system including the electric shielding device of the embodiment according to the present invention will be described with reference to FIG. FIG. 12 is a diagram schematically showing an example of a remote control system including the electric shielding device of one embodiment according to the present invention.

The remote control system shown in FIG. 12 includes the electric shielding device illustrated in FIGS. 1 and 11 described above, a smart speaker 100 having an Internet-based network connection, a mobile terminal 200 such as a smartphone, a router 300, and a cloud server 400. , And an operation signal transmitting device 500.

The smart speaker 100 is a device that recognizes the voice of the registered user U and performs processing according to the voice by the AI (Artificial Intelligence) function. In this example, it is used for operating an electric shielding device that uses this AI function. Application software is installed. This application software recognizes a voice indicating a specific language related to the opening / closing operation of the shielding material, converts it into an open command, a closing command, and a stop command as commands related to the opening / closing operation, and further, various commands related to this converted operation. Is made to function in the smart speaker 100 as a voice / communication signal conversion unit 600 that converts an IP (Internet Protocol) format communication signal. Further, various commands related to the converted operation are stored in the payload of the IP format communication signal with the own device as the transmission source and the destination as the operation signal transmission device 500 in the IP header of the communication signal. As a result, when the smart speaker 100 recognizes the voice of the registered user U indicating a specific language related to the opening / closing operation, the smart speaker 100 issues various commands related to the converted operation via the router 300 (or may be via the mobile terminal 200). It has a function of transmitting the including communication signal to the operation signal transmission device 500.

The mobile terminal 200 is a communication device such as a smartphone that enables mobile communication, and application software that presents an operation screen 200a for operating the electric shielding device is installed. In addition, as a function of this application software, a speaker indicating a specific language related to the opening / closing operation of the shielding material is recognized, converted into an open command, a closing command, and a stop command as commands related to the opening / closing operation, and further converted. The mobile terminal 200 can be made to function as a voice / communication signal conversion unit 600 that converts various operations-related commands into IP format communication signals, and further, the smart speaker 100 is provided with the function of the voice / communication signal conversion unit 600. Alternatively, the voice / communication signal conversion unit 600 may be made to function by the application software on the mobile terminal 200 side in a state of being connected to the smart speaker 100 by communication.

On the operation screen 200a presented to the mobile terminal 200, as shown in the figure, an open button "(OPEN or Δ, etc.)" 221, a close button "(CLOSE, ▽, etc.)" 222, and a stop button "(STOP, etc.)" , Or □, etc.) ”223 is presented. Fully closed tilt button "(↑ / ↓)" 226 and reverse fully closed tilt button "(↓ / ↑)" 227 are provided as operation buttons for operating the tilt operation of the slats.

You can send a stop command. Further, the fully closed tilt button "(↑ / ↓)" 226 and the reverse fully closed tilt button "(↓ / ↑)" 227 are used to continuously operate the tilt operation of the slats while being pressed. Commands are continuously issued, and when the press is released, continuous command transmission is stopped.

Therefore, the smart speaker 100 and the mobile terminal 200 issue one of an open command, a close command, and a stop command to the transmission signal transmission device 500 so as to transmit the operation signal toward the electric shielding device to be operated. It is configured as an operation terminal that transmits communication signals including.

In particular, the smart speaker 100 or the mobile terminal 200 recognizes a voice indicating a specific language related to the opening / closing operation of the shielding material, converts it into an open command, a closing command, and a stop command as commands related to the opening / closing operation, and this conversion. By providing the voice / communication signal conversion unit 600 that converts the command into an IP format communication signal including the command, the transmission signal transmission device 500 is made to transmit the operation signal toward the electric shielding device to be operated. Based on the above, it is configured as a voice operation device that transmits a communication signal including any one of an open command, a close command, and a stop command.

The router 300 is a device that relays communication signals between each communication device (in this example, between the smart speaker 100, the mobile terminal 200, the cloud server 400, and the operation signal transmission device 500).

The cloud server 400 is a server that operates on the Internet that relays communication between the mobile terminal 200 and the operation signal transmission device 500 (furthermore, relays communication between the smart speaker 100 and the operation signal transmission device 500). It may be a system configuration to be used.) A home server (not shown) that has the same function as the cloud server 400 and monitors and manages the open / closed state of the shielding material of one or more electric shielding devices to be operated may be provided instead of the cloud server 400. Alternatively, the system configuration may further include the home server (not shown).

When the operation signal transmitting device 500 receives the communication signal received from the smart speaker 100 or the mobile terminal 200, the operation signal transmitting device 500 extracts various commands related to the operation stored in the communication signal, and one or more electric shielding devices to be operated. It is a device that transmits by short-range wireless communication (or may be wired communication), and is a device dedicated to the remote operation system in this example. An external device such as a wired switch 21, an infrared remote controller 22, a wireless remote controller 23, or a communication terminal such as a personal computer (PC) 24, which has a function of designating each command by the button operation described above and transmitting the operation signal, may be used. It can also be configured as an operation signal transmitter 500.

In the remote control system shown in FIG. 12 configured in this way, as described above, the control device 10 of the electric shielding device controls each of the plurality of shielding materials arranged in the front and rear so as to be electrically able to move up and down. However, without requiring an individual command to identify each shielding material, it is electrically operated by an operation signal having only one set of open command, closing command, and stop command as commands related to the opening / closing operation of the shielding material. It can be raised and lowered with.

Then, as described below, the operation using the voice or the operation screen shown in FIG. 12 is electrically operated by an operation signal having only one set of an open command, a close command, and a stop command as commands related to the opening / closing operation of the shielding material. 13 (a) and 13 (b) show an operation example of the same-direction lowering control and an operation example of the same-direction ascending control in the electric shielding device of one embodiment according to the present invention, respectively.

[When operating by voice]
For example, in order to perform a lowering operation of each of the plurality of shielding materials arranged before and after by voice, the function of the voice / communication signal conversion unit 600 in the smart speaker 100 (or the voice / communication signal conversion unit 600 in the mobile terminal 200) is used. (By the function of), one of the predetermined shielding materials (example: rear screen 6R) can be lowered by the first "close the screen" voice (see FIG. 13 (a-1)). The other shielding material (eg, front screen 6F) can be lowered by a second consecutive "close screen" voice (see FIG. 13 (a-2)).
Further, for example, in order to perform an ascending operation of each of the plurality of shielding materials arranged before and after by voice, the function of the voice / communication signal conversion unit 600 in the smart speaker 100 (or voice / communication signal conversion in the mobile terminal 200) is used. (By the function of part 600), the other shielding material (eg, front screen 6F) can be raised by the first "open screen" voice (see FIG. 13 (b-1)), and is continuous. The second "open screen" voice can raise one of the shielding materials (eg, rear screen 6R) (see FIG. 13 (b-2)).

[When operating from the operation screen]
On the other hand, in the operation on the operation screen 200a on the mobile terminal 200, in order to perform the lowering operation of each of the plurality of shielding materials arranged in the front and rear, the first lowering command is transmitted by pressing the close button 222 once. , One of the predetermined shielding materials (eg, rear screen 6R) can be lowered (see FIG. 13 (a-1)), and the second lowering command is issued by the second pressing of the continuous closing button 222. Upon transmission, the other shielding material (eg, front screen 6F) can be lowered (see FIG. 13 (a-2)).
Further, in the operation on the operation screen 200a on the mobile terminal 200, in order to perform the raising operation of each of the plurality of shielding materials arranged in the front and rear, the first raising command is transmitted by pressing the open button 221 once. , The other shielding material (eg, front screen 6F) can be raised (see FIG. 13 (b-1)), and when the second raising command is sent by the second pressing of the open button 221 in succession, One of the shielding materials (eg, rear screen 6R) can be raised (see FIG. 13 (b-2)).

The 60 is provided with an insertion hole formed of a round hole, an elongated hole, or the like, and an elevating cord 3L hanging from the head box 1 and penetrating the intermediate rail 7U is inserted into the insertion hole. Therefore, the elevating cord 3L hangs down on the back side of the lower screen 6L so that it cannot be visually recognized from the front as shown in FIG. 14B to enhance the aesthetic appearance. However, according to the present invention, an insertion hole may be provided in a substantially central portion of the lower screen 6L in the front-rear direction so that the elevating cord 3L inserted through the insertion hole can be visually recognized from the front. Further, as shown in FIG. 14C, a pitch holding cord 4L is hung from the head box 1 behind the elevating cord 3L, and the lower end thereof is attached to the bottom rail 7L. A large number of annular support cords 40 are provided at equal intervals in the pitch holding cord 4L, and an elevating cord 3L is inserted through the support cord 40. Then, when the bottom rail 7L is lowered to extend the lower screen 6L, the protruding pieces 60 are supported by the support cords 40 of the pitch holding cords 4L so that the folds of the lower screen 6L are held at substantially equal intervals. It has become.

Winding drums 51U and 51L are arranged side by side in front of and behind each of the support members 5 arranged at appropriate positions (two locations on the left and right in this example) in the head box 1 and are rotatably supported.

The upper end of the elevating cord 3U (which is a string-shaped cord in this example, but may be a tape-shaped elevating tape) is attached to each winding drum 51U so that it can be wound or rewound. The lower end penetrates an insertion hole formed in each protruding piece 60 provided on the outdoor side of the upper screen 6U and is attached to the intermediate rail 7U. The take-up drum 51U is formed so that the diameter gradually decreases in one direction in the axial direction. In this example, the string-shaped elevating cord 3U is spirally wound around the take-up drum 51U. There is.

Further, the upper end of the elevating cord 3L (which is a string-shaped cord in this example, but may be a tape-shaped elevating tape) is attached to each winding drum 51L so that it can be wound or rewound, and the elevating cord is attached. The lower end of the 3L penetrates an insertion hole formed in each protruding piece 60 provided on the outdoor side of the upper screen 6U, further penetrates the intermediate rail 7U, and is provided on the outdoor side of the lower screen 6L. It penetrates the insertion hole formed in the projecting piece 60 and is attached to the bottom rail 7L. The take-up drum 51L is formed so that the diameter gradually decreases in one direction in the axial direction. In this example, the string-shaped elevating cord 3L is spirally wound around the take-up drum 51L. There is.

A drive shaft 2U is inserted through the central shaft of each take-up drum 51U, the rotation of the drive shaft 2U is transmitted to the take-up drum 51U, and the driving force of the take-up drum 51U is transmitted to the drive shaft 2U. ing.

Similarly, a drive shaft 2L is inserted through the central shaft of each take-up drum 51L, the rotation of the drive shaft 2L is transmitted to the take-up drum 51L, and the driving force of the take-up drum 51L is transmitted to the drive shaft 2L. It has become like.

By the way, the take-up drum 51U is provided with a clutch mechanism 52U as an obstacle detection / stopping device that locks the rotation of the drive shaft 2U when the lowering of the intermediate rail 7U is hindered by contact with an obstacle. Further, the take-up drum 51L is provided with a clutch mechanism 52L as an obstacle detection / stopping device that locks the rotation of the drive shaft 2L when the lowering of the bottom rail 7L is hindered by contact with an obstacle.

One end of the drive shaft 2U is connected to the output shaft of the motor 9U via the drive shaft coupler 20U, and the rotation of the output shaft of the motor 9U is transmitted to the drive shaft 2U. Therefore, the drive shaft 2U is rotated by the driving force of the motor 9U, and the elevating cord 3U is wound or rewound by the take-up drum 51U based on the rotation of the drive shaft 2U, so that the intermediate rail 7U can be raised and lowered. As a result, the upper screen 6U can be raised and lowered. Since the take-up drum 51U uses the tension related to the elevating cord 3U (the own weight of the upper screen 6U and the intermediate rail 7U) when the upper screen 6U is lowered, the driving force thereof is from the take-up drum 51U to the drive shaft 2U. And adjusts the driving force related to the driving shaft 2U to control the descent.

Further, one end of the drive shaft 2L is connected to the output shaft of the motor 9L via the drive shaft coupler 20L, and the rotation of the output shaft of the motor 9L is transmitted to the drive shaft 2L. Therefore, the bottom rail 7L can be raised and lowered by rotating the drive shaft 2L with the driving force of the motor 9L and winding or rewinding the elevating cord 3L with the take-up drum 51L based on the rotation of the drive shaft 2L. As a result, the lower screen 6L can be raised and lowered. Since the take-up drum 51L uses the tension related to the elevating cord 3L (the own weight of the lower screen 6L and the bottom rail 7L) when the lower screen 6L is lowered, the driving force thereof is from the take-up drum 51L to the drive shaft 2L. And adjusts the driving force related to the driving shaft 2L to control the descent.

Reference numeral 10 denotes a configuration in which each component of the control device 10 shown in FIG. 3 can be diverted to perform elevating control with respect to the upper screen 6F and the lower screen 6L, and substantially the same control can be performed. The illustrated description will be omitted.

For example, by configuring the motors 9U and 9L with DC motors, respectively, by controlling the duty ratio of the pulse signal supplied from the control device 10 to the motors 9U and 9L, the control device 10 controls the rotation speeds of the motors 9U and 9L. Can be controlled. Further, encoders 8U and 8L for detecting the rotation speeds and rotation amounts of the drive shafts 2U and 2L are arranged in the head box 1, and the control device 10 uses the pulse signals output from the encoders 8U and 8L. Based on this, the speed of the encoder pulse and the count value of the number of pulses are managed to control the rotation speed and the amount of rotation of the motors 9U and 9L. By such an operation, the control device 10 appropriately adjusts the ascending / descending speed of the upper screen 6U or the lower screen 6L in response to various commands included in the operation signal, and also adjusts the ascending / descending speed of the upper screen 6U or the lower screen 6U or the lower part. The ascending / descending stop position of the screen 6L is controlled.

In the electric pleated screen of the present embodiment configured in this way, the intermediate rail 7U is pulled up to just below the head box 1, and the upper screen 6U is folded between the head box 1 and the intermediate rail 7U, and the bottom rail is folded. When the 7L is lowered, the lower screen 6L from the head box 1 is shielded to a desired position.

Further, when the intermediate rail 7U is lowered to the top of the bottom rail 7L with the bottom rail 7L lowered to the lower limit, the lower screen 6L is folded between the intermediate rail 7U and the bottom rail 7L, and is intermediate between the head box 1 and the head box 1. The upper screen 6U is shielded from the rail 7U. Therefore, for example, if the upper screen 6U is used as a daylighting material and the lower screen 6L is used as a light-shielding material, the degree of freedom in adjusting the amount of daylighting can be increased.

Then, if the bottom rail 7L is lowered to the lower limit and the intermediate rail 7U is positioned between the head box 1 and the bottom rail 7, the soft light transmitted through the upper screen 6U made of the daylighting material can be collected. can.

When the bottom rail 7L is pulled up to the upper limit and opened, the bottom rail 7L is pulled up together with the intermediate rail 7U, and the upper screen 6U and the lower screen 6L are folded between the head box 1 and the bottom rail 7L. can do.
