DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) First Embodiment (A-1) Configuration of First Embodiment Hereinafter, a first embodiment of an opening device and a flexible member exercising device according to the present invention will be described. This will be described in detail with reference to the drawings. The opening device according to the first embodiment includes a flexible member exercising device.

FIG. 2 is a schematic perspective view showing an essential part of the opening device 1 of the first embodiment. FIG.
2 is a longitudinal sectional view taken along the line II in FIG.
Also, components other than the components shown in FIG. FIG.
FIG. 4 is a front view of the upper bracket portion in FIG. 1 (a front view as seen from the indoor side described later.
FIG. 5 is a sectional view taken along line IV-IV, and FIG. 5 is a sectional view taken along line VV in FIG.

As shown in FIGS. 1, 4 and 5, the opening device 1 of the first embodiment is provided as a device for shielding the indoor side of an opening 2 for communicating indoors and outdoors. . The sash 3 is provided on the outdoor side,
The sash 3 is irrelevant to the features of the first embodiment, and further description will be omitted.

As shown in FIG. 2, the opening device 1 has a sheet-like member 10, an upper winding shaft 11, a lower winding shaft 12, an upper guide roller 13, and a lower guide roller 14 as main components. .

As will be described later, the sheet-like member 10 is sufficiently longer than the vertical length of the opening 2 to be shielded, and one end in the longitudinal direction is attached to the upper winding shaft 11 and the other end is connected to the lower side. It is attached to the winding shaft 12 and is wound around both the upper winding shaft 11 and the lower winding shaft 12. The direction of the portion of the sheet-like member 10 pulled out from the upper winding shaft 11 is changed by the upper guide roller 13 provided close to the upper winding shaft 11 so as to be along the vertical direction. The direction of the sheet-like member 10 pulled out from the side take-up shaft 12 is also changed by the lower guide roller 14 provided close to the lower take-up shaft 11 so as to be along the vertical direction. . That is, the position of the portion blocking the opening 2 of the sheet-shaped member 10 between the upper guide roller 13 and the lower guide roller 14 is always the same.

The upper winding shaft 11 functions as a drive shaft for moving the sheet-like member 10 upward.
The lower winding shaft 12 functions as a drive shaft when the sheet-shaped member 10 is moved downward.

A pair of sprockets 15 and 1 are provided at one end (for example, the right end as viewed from the indoor side) of the upper winding shaft 11.
The driving force of a motor (upper motor) 18 is transmitted via a motion transmission mechanism including the motor 6 and the chain 17 (or another motion transmission mechanism including a belt and a pulley).

On the other hand, the other end of the upper take-up shaft 11 (for example, the left end as viewed from the indoor side) is connected to a motion transmission mechanism (a belt and a pulley such as a belt and a pulley) including a pair of sprockets 19 and 20 and a chain 21. (A motion transmission mechanism may be used), and is electrically connected to a brake 22 that can electrically vary the braking force. With the brake 22, the rotation of the upper winding shaft 11 can be suppressed.

Similarly, a pair of sprockets 2 is attached to one end (for example, the right end when viewed from the indoor side) of the lower winding shaft 12.
The driving force of a motor (lower motor) 26 is transmitted via a motion transmission mechanism composed of 3 and 24 and a chain 25.

The other end of the lower take-up shaft 12 (for example, the left end as viewed from the indoor side) is electrically connected to a braking force via a motion transmission mechanism including a pair of sprockets 27 and 28 and a chain 29. Is connected to a brake 30 which can change the lower take-up shaft 12.
Rotation can be suppressed.

At least at the connection end of the upper winding shaft 11 and the lower winding shaft 12 with the motors 18 and 26, a width-direction position regulating circle for regulating the position of the sheet-like member 10 in the width direction. Plates 31 and 32 are provided.

The upper winding shaft 11 and the lower winding shaft 12
A width-direction position regulating disk may be provided on the other end side of the sheet, and a width-direction position regulating disk may also be provided on the upper guide roller 13 and the lower guide roller 14.

The upper take-up shaft 11, the lower take-up shaft 12, the upper guide roller 13 and the lower guide roller 14 are different depending on whether they are set up or down, but the same member can be used. However, if the same members are applied to the motors 18 and 26 and the brakes 22 and 30 irrespective of the difference between the upper and lower parts (for example, if these members are unitized), unlike the first embodiment, If the motor 18 is provided on the “right side” when viewed from the indoor side, the lower motor 2
6 must be provided on the "left side" when viewed from the indoor side.

However, in the first embodiment,
As described above, the upper motor 18 and the lower motor 26 are provided on the same side. This is because, even when the sheet-shaped member 10 is moved up or down, the traveling direction is correctly along the vertical direction, and an attempt is made to prevent even slight meandering or skewing. Hereinafter, it will be described that if the upper motor 18 and the lower motor 26 are provided on the same side, slight meandering and skewing of the sheet-shaped member 10 can be prevented.

The vertical length of the opening 2 is, for example, 1 to 1.
Since the distance is about 3 m, and the distance between the upper winding shaft 11 and the lower winding shaft 12 also corresponds to the distance, the sheet member 10 travels a considerable distance. In such a case, if the intended configuration or method for regulating the position in the width direction is not applied, meandering or skew of the sheet-like member 10 may occur.

The inventor of the present invention rotates the winding shaft (11 or 12) during the repetition of the trial manufacture and the durability test, and the like. (In the end portion side), it was found that the position in the width direction of the sheet-like member 10 on the winding shaft (11 or 12) slides very little. Winding shaft (11
And 12) are made of a rigid body, but when viewed microscopically, the end where the driving force is introduced is twisted to advance, and It is considered that the tension vector has not only a vector component in the intended traveling direction but also a vector component toward the end where the driving force is introduced.

Considering the property that the position in the width direction of the sheet-like member 10 slides toward the end where the driving force is introduced (to the end where the motor is provided) as described above, If the motors 18 and 26 are provided on different sides, since the sliding direction is different between the upward movement and the downward movement, skew is likely to occur, and meandering is likely to occur depending on the uniformity of the material of the sheet-like member 10.

On the other hand, when the upper and lower motors 18 and 26 are provided on the same side as in the first embodiment, the directions in which the upper and lower motors are slid are the same. By offsetting the vector component in the sliding direction by the drag from the width-direction position regulating discs 31 and 32, the sheet-like member 10 travels only in the intended direction at both the time of the upward movement and the time of the downward movement. And meandering and skewing can be prevented.

Each of the brakes 22 and 30 is basically a lower winding shaft 12 or an upper winding shaft 11 of the other of the upper winding shaft 11 or the lower winding shaft 12 to which the brakes 22 and 30 are connected.
Is a driving shaft for moving the sheet-shaped member 10, the braking force is controlled by a control means 95 (see FIG. 7) described later, whereby the running of the sheet-shaped member 10 is controlled. Time tension is controlled.

FIG. 6 is a plan view showing a state where the sheet-like member 10 has been removed from the apparatus and extended.

As shown in FIG. 6, the sheet-like member 10
A plurality of (four in FIG. 6) shielding function regions 7 having an area and a shape substantially equal to the area and the shape of the opening 2 to be shielded
0-1 to 70-4 are arranged in the longitudinal direction. The upper and lower ends of the sheet-shaped member 10 are provided with discarded winding portions 71U and 71D as attachment margins for the upper winding shaft 11 and the lower winding shaft 12, respectively. In addition, between the shielding functional regions, the connecting portions 72-1 and 72 function as margins when clearly defining the shielding functional region and attaching a sheet constituting the shielding functional region.
-2 and 72-3 are provided.

Each of the shielding function areas 70-1,..., 70-4
Are different in function when they are located at a position where they block the opening 2. Here, as a sheet-like member (sheet base material) before completion, a sheet in which the position of each shielding function area is a through hole is prepared, and a sheet having a different shielding function is provided with a through hole at the position of each shielding function area. And stick it to close it,
The sheet member 10 may be completed. In addition, as a sheet member (sheet base material) before completion, a light-transmitting 1
The sheet-shaped member 10 may be completed by preparing a sheet made of sheets, and applying a sheet having a different shielding function on the position of each shielding function area. Further, the sheet-like member 10 may be completed by performing a printing process or a partial punching process on the sheet base material. Furthermore,
Prepare each sheet part as each shielding function area,
The sheet-like member 10 may be completed by joining the sheet portions in the longitudinal direction.

As an example of the sheet member 10, the shielding function area 70-1 is a light shielding sheet, and the shielding function area 70-
2 is a shoji paper, the shielding function area 70-3 is a net,
An example in which the shielding function region 70-4 is a completely transparent hole can be given.

In the case where the sash 3 is provided on the outdoor side as in the first embodiment, in consideration of the operation of the sash 3, a shield function area having a completely transparent hole is prepared. That is useful.

The shielding function of the shielding function area 70-i is not limited to the above. For example, a plurality of objects having different light-shielding amounts may be provided, and may have a shielding function such as sound insulation, heat insulation, and blindfolding, and further provide an artistic background such as a picture pattern or a character pattern. It may be.
Modifications from this viewpoint will be described in more detail.

A plurality of marks 73R and 73L used for managing the position of the shielding function area are provided at the right end and the left end (only one end may be provided) of the sheet member 10. The marks 73R and 73L may be code data indicating the position of a bar code or the like, but here, it is assumed that light is simply blocked. The right end and / or left end area of the sheet member 10 other than the marks 73R and 73L is translucent. In addition, the mark 73 </ b> R distinguishes each shielding function area, and the mark 73 </ b> L is for detecting the upper and lower end positions of the sheet-shaped member 10.

Mark 73R for distinguishing each shielding function area
Is a set of three boundary portions of each shielding function area. Of the three marks, the middle mark 73R-2 functionally instructs to stop the motor being driven, and the upper mark 73R-1 switches from constant-speed running to deceleration during upward movement. The timing is indicated, and the lower mark 73R-3 indicates the timing of switching from the constant speed traveling to the deceleration during the downward movement.

The two marks 73L for detecting the upper and lower end positions of the sheet-like member 10 are one set. The mark 73L-1 near the end of the two marks indicates the stop of the motor being driven, and the mark 73L-1 far from the end.
Reference numeral 2 designates a timing for switching from constant speed traveling to deceleration.

In the case of the mark shown in FIG. 6, the marks 73L-1 and 73L-2 for detecting the upper end position are
It also serves as a deceleration mark and a stop mark of the uppermost shielding function area 70-1 at the time of downward movement, and the lowermost position detection marks 73L-1 and 73L-2 are the lowermost shielding function at the time of upward movement. It also serves as a deceleration mark and a stop mark in the area 70-4.

Although not shown in FIGS. 2 to 5, a photoelectric sensor (mark detection sensor) including a light emitting unit and a light receiving unit for detecting the marks 73R and 73L is provided. Hereinafter, the photoelectric sensor corresponding to the mark 73R is referred to as an area position sensor, and the photoelectric sensor corresponding to the mark 7373L is referred to as a sheet upper / lower sensor.

The installation positions of the area position sensor and the upper and lower end sensors of the sheet may be any positions as long as the marks 73R and 73L can be detected and the traveling of the sheet-like member 10 can be controlled.

Although a reflection type photoelectric sensor can be used (this case also constitutes another embodiment of the present invention), the reflection type sensor has a sheet-like member 10 whose wavy running. Detection accuracy is lower than that of the transmission type.

The distance between the light emitting unit and the light receiving unit constituting the photoelectric sensor is about 5 to 10 cm. For example, it is preferable to use a light emitting unit and a light receiving unit that can cope with a distance of about 3 m. This is in consideration of the case where the end of the sheet-shaped member 10 becomes dirty due to long-term use. Therefore, the light shielding property of the mark 73 is set to be considerably large.

FIG. 7 is a block diagram showing an electrical configuration of the opening device 1 according to the first embodiment.

The opening device 1 according to the first embodiment has, as an electrical configuration, the above-described upper motor 18, lower motor 26, upper brake 22, lower brake 30, and area position sensor (reference numeral 90 in FIG. 7). ), And upper and lower sheet sensors (represented by reference numeral 91 in FIG. 7), and further have the following configuration.

Power supply protection circuit 92, power-on switch 9
3, an operation unit 94, a control unit 95, a motor drive unit 96, a brake drive unit 97, and an abnormality notification unit 98.

The opening device 1 according to the first embodiment is supposed to use a commercial power supply as a power supply, so that a commercial power supply can be taken in through a power supply protection circuit 92 that performs overcurrent protection and overvoltage protection. It has been done.

The power switch 93 is connected to the power protection circuit 9.
2 for taking in the commercial power supply through the inside.

The operation section 94 receives an operation for instructing the sheet-like member 10 to feed the shielding function area and gives the operation to the control section 95.

Here, when the number of the shielding function areas in the sheet-like member 10 is small (for example, about four), the operation keys corresponding to the respective shielding function areas on a one-to-one basis (the operation keys are provided with the shielding keys). Characters representing functions (for example, “light-shielding sheet”, “screen door”, “shoji paper”, “through-hole”, etc.) are provided, and the operation of the operation keys is performed by opening the shielding function area. The command may be regarded as a command to be positioned at the second shielding position. In this case, a storage unit is required in the control unit 95 for storing information about which shielding function area is located at the shielding position of the opening 2.

When the number of shielding function areas in the sheet-like member 10 is large, a key for instructing to move up by one shielding function area or a key for instructing to move down by one shielding function area is provided. It is also possible to provide an instruction to feed in units of one shielding function area.

Further, the number of the shielding function areas to be moved up or down may be inputted by numeral. In this case, in the control unit 95, a storage unit that stores information on the number of the shielding function region at the shielding position of the opening 2 counting from the top or bottom is stored. Required.

The control unit 95 includes, for example, a sequencer, a relay, and a relay contact.
When the switching of the shielding function area positioned at the shielding position is instructed, the entire movement operation and stop operation of the shielding function area (sheet-like member 10) are controlled. Control unit 9
In this control, the control unit 5 checks the moving position and the like based on the area position sensor 90 and the upper and lower end sensors 91 of the sheet and switches the control content. The control unit 95 controls the movement operation and the stop operation of the shielding function area by giving predetermined drive signals and control signals to the motor drive unit 96 and the brake drive unit 97.

The control section 95 also monitors whether or not an abnormality has occurred during the switching operation of the shielding function area located at the shielding position of the opening 2 (during the travel of the sheet-like member 10). When an abnormality is detected, the motors 18 and 26 are stopped or a notification start signal is given to the abnormality notification unit 98.

The motor drive section 96 drives and controls the upper motor 18 and / or the lower motor 26 under the control of the control section 95.

(In FIG. 7, "M" indicates the motor body, and "B" indicates the motor body).
Represents a brake). In addition, the motor driving unit 96
Supplies a motor drive signal corresponding to the speed instructed by the control unit 95. For example, when the upper motor 18 and the lower motor 26 are induction motors, the motor drive unit 96 includes an inverter, and the inverter changes the cycle or voltage of the PWM signal applied to the induction motor to reduce the speed. Make it variable. If the upper motor 18 and the lower motor 26 are three-phase motors, the motor driving unit 96 generates a three-phase drive signal from a commercial power supply.

The brake drive unit 97 controls the upper brake 22 and / or the lower brake 30 under the control of the control unit 95.

As described above, the upper motor 18 and the lower motor 26 themselves have a built-in brake (lock function), but the brake in the motor can only unlock or lock, and the braking force is variable. There is no control. Therefore, the independent upper brake 22 and lower brake 30 that can electrically change the braking force are applied, and as described above, the tension at the time of traveling of the sheet-shaped member 10 becomes a value within the intended tension range. In addition, the braking force of the upper brake 22 and / or the lower brake 30 is changed by the brake driving unit 97.

It is preferable that the number of steps of the braking force that can be taken by the upper brake 22 and the lower brake 30 is plural. In the following description of the operation, the upper brake 22 and the lower brake 30 will be described as being able to take at least three states: a state where there is no braking force, a state where the braking force is weak, and a state where the braking force is strong. The state where the braking force of the upper brake 22 is weak and the state where the braking force is strong are not the same as the state where the braking force of the lower brake 30 is weak and the state where the braking force is strong. The reason for this will be described later.

The abnormality notification unit 98 is, for example, an LED and / or a buzzer, and performs an abnormality notification operation when a notification activation signal is given from the control unit 95.

For example, all may be provided in the lower case 57. In this case, the power-on switch 93 and the operation unit 9
It is preferable that the abnormality notification section 98 be provided on the surface of the lower case 57. Further, for example, all of the components 92 to 98 may be provided at positions separated from the upper case 56 and the lower case 57. Further, for example, a power-on switch 93, an operation unit 94, and an abnormality notification unit 98 are provided at positions away from the upper case 56 and the lower case 57, and the power protection circuit 92, the control unit 95, the motor drive unit 96, and the brake drive The part 97 is connected to the upper case 56 or the lower case 57.

(A-2) Operation of First Embodiment Next, the operation of the opening device 1 of the first embodiment having the above configuration will be described. In the following description, it is assumed that the operation unit 94 can instruct only the upward movement or the downward movement of only one shielding function area.

First, the operation for moving the sheet-like member 10 upward will be described in detail with reference to the flowchart of FIG.

When the user wants to move the shielding function area, which is one shielding function area below, from the shielding function area which is currently shielding the opening 2 to a position where the opening 2 is to be shielded, After the ON switch 93 is turned on, the operation unit 94 is instructed to move upward by one shield function area. At this time, the control unit 95 starts a series of processes shown in FIG.

In the case of the opening device 1 of the first embodiment, since the shielding function area is changed several times a day, the user needs to turn on the power during the period in which the shielding function area is not changed. Often the switch 93 will be off. When the power-on switch 93 has already been turned on when the user wants to change the shielded function area, the user immediately performs an operation of instructing the operation unit 94 to move up by one shielded function area.

The control unit 9 which has started a series of processes shown in FIG.
5 is the output signal of the sheet upper and lower edge sensor,
Based on the position information in the sheet-shaped member 10 of the shielding function area that is currently shielding the opening 2 and is internally stored,
It is determined whether it is possible to execute the upward movement only for the designated one shielding function area (step 100). That is, it is determined whether or not the shielding function area that is currently blocking the opening 2 is the lowest shielding function area of the sheet-shaped member 10.

If the area is the lowermost shielding function area, it is not possible to perform the upward movement for the designated one shielding function area. Therefore, the control section 95 causes the abnormality notification section 98 to execute the operation ignoring notification (step 101). The series of processes shown in FIG.

If the shielding function area that is currently blocking the opening 2 is not the lowest shielding function area of the sheet-like member 10, the control unit 95 operates the brakes in the upper motor 18 and the lower motor 26. The state is switched to the unlocked state, the upper brake 22 is set to a state where the braking force does not work, and the lower brake 30 is set to a state where the braking force is weak (step 102).

The control unit 95 starts the built-in start time elapse timer that measures the time elapsed from the start time, starts the upper motor 18, and performs acceleration control based on the time measured by the start time elapse timer. Do (Step 10
3, 104).

Thereafter, the control unit 95 determines whether or not the time measured by the start time elapse timer has exceeded a first predetermined time which defines the timing of switching from acceleration control to constant speed traveling (step 105). If it has not exceeded the first predetermined time, the control section 95 returns to step 104 described above and continues the acceleration control.

For example, assuming that the speed at the constant speed traveling during the upward movement is X, when a drive signal (voltage) for causing the upper motor 18 to execute the speed X is given at the time of starting, the speed changes from 0 to X. The speed changes abruptly, so that the sheet-like member 10
Of the sheet-like member 10 may be greatly increased.

Therefore, an acceleration control is introduced. In the acceleration control, for example, immediately after the start, a drive signal for executing the speed X / N (N is an integer of 2 or more) is given for a predetermined time T,
During the next time T, a drive signal for executing the speed 2X / N is given, and thereafter, a drive signal for executing 3X / N, 4X / N,. Take it to X. The time of switching to the drive signal for executing the speed X determined by the time T is the above-described first predetermined time.

When the acceleration end timing comes, the control unit 95
Is switched to constant speed running (constant speed upward motion) (step 10).
6). During traveling at a constant speed, the control unit 95 determines that the time counted by the start time elapse timer is longer than the normal time (time from start to stop) required to move up by one shield function area.
(Step 10)
7).

Here, the fact that a positive result is obtained means that the deceleration mark is not detected even after the second predetermined time longer than the normal time required for the upward movement for one shielding function area. In other words, the control unit 95 performs processing when an abnormality occurs, such as stopping the upper motor 18 or activating the abnormality notification unit 98 (step 108), and ends the series of processing illustrated in FIG.

If the second predetermined time has not elapsed since the start of the motor, the control section 95 checks whether or not a deceleration mark has been detected (step 109). Return to and continue the constant speed ascent.

When the deceleration mark is detected, the control unit 95
Switches the lower brake 30 to a state where the braking force is strong,
Further, a built-in deceleration mark detection time elapse timer for counting the time elapsed from the detection of the deceleration mark is started (step 110).

Then, deceleration control is performed on the upper motor 18 (step 111). During this deceleration, the control unit 9
Step 5 confirms whether or not the time counted by the start time elapse timer has exceeded a second predetermined time longer than the normal time required for the upward movement of one shielding function area (whether or not an abnormality has occurred) (step S5). 112), if it has exceeded, a process at the time of occurrence of an abnormality such as stopping the upper motor 18 or activating the abnormality notification unit 98 is performed (step 108), and the series of processes shown in FIG. 8 is ended.

During the deceleration, the control unit 95 sets the third timer which is longer than the time required from the detection of the deceleration mark to the detection of the stop mark in the normal deceleration operation. It is checked whether or not a predetermined time has passed (whether or not an abnormality has occurred) (step 113). If the time has exceeded, an abnormality such as stopping the upper motor 18 or activating the abnormality notification unit 98 is detected. The processing at the time is performed (step 108), and the series of processing shown in FIG. 8 is terminated.

When no abnormality is detected during the deceleration period, the control unit 95 checks whether or not a stop mark has been detected (step 114). If no stop mark has been detected, the control unit 95 proceeds to step 111. Back, upper motor 1
8, the deceleration control is continued.

Here, in the deceleration control for the upper motor 18, since the braking force of the lower brake 30 has already been increased,
The number of speed steps may be considerably smaller than during acceleration. In addition, deceleration is achieved only by the strong braking force of the lower brake 30,
If the stop can be executed without any problem, the deceleration control in step 111 may be omitted.

When the stop mark is detected, the control unit 95
Stops the rotation of the upper motor 18 and
Then, both the internal brakes of the lower motor 26 and the lower motor 26 are locked, and the upper brake 22 and the lower brake 30 are both in a state where the braking force does not work (step 115), and the series of processes shown in FIG.

FIG. 8 shows the operation at the time of the upward movement of one shielding function area. However, the same processing is performed at the time of the downward movement of one shielding function area. That is, the "upper motor 18" in FIG.
6 may be read as "upper motor 18", "upper brake 22" as "lower brake 30", and "lower brake 30" as "upper brake 22".

Here, the upward movement is performed in the direction opposite to the direction of gravity, while the downward movement is performed along the direction of gravity.
In the first embodiment, the operation at the time of the upward movement is slightly different from the operation at the time of the downward movement.

That is, at the time of the downward movement, the sheet-like member 10 may be pulled out from the upper guide roller 13 by gravity. Therefore, the lower braking force of the upper brake 22 and the strong braking force of the upper brake 22 are higher than the lower brake 30 which operates at the time of the upward movement. Both braking forces are increased. For example, in relative terms,
If the weak and strong braking forces of the lower brake 30 operating during upward movement are 0.1 and 2, the weak and strong braking forces of the upper brake 22 operating during downward movement are reduced to 3.5 and 9, respectively. I do.

Further, in consideration of the influence of gravity, the time for switching from starting to constant speed traveling during downward movement may be shorter than the time for switching from starting to constant speed traveling during upward movement described above.
The speed itself at the constant speed traveling may be changed from the time of the upward movement.

(A-3) Effect of First Embodiment As described above, according to the opening device 1 of the first embodiment, a plurality of shielding function areas having different shielding functions are arranged in the longitudinal direction. The sheet-shaped member 10 is connected to the upper and lower winding shafts 11 and
2 is driven so that a desired shielding function area can be stopped at a position where the opening 2 is shielded, so that an apparatus capable of providing many shielding functions can be realized.

Further, according to the flexible member exercising device (sheet-like member exercising device) of the first embodiment, the upper winding shaft 11 serving as the driving shaft during upward movement takes in the driving force from the upper motor 18. Part side and lower winding shaft 12 which becomes a drive shaft at the time of downward movement
However, since the same side is used as the end side that takes in the driving force from the lower motor 26, it is possible to prevent skewing and meandering during upward movement and downward movement.

Further, according to the flexible member exercising device (sheet-like member exercising device) of the first embodiment, the upper winding shaft 1
An upper brake 22 and a lower brake 30 are provided at the end opposite to the end where the first and lower winding shafts 12 take in the driving force from the upper motor 18 and the lower motor 26 so that the braking force can be switched in multiple stages. When the upper motor 18 is providing the driving force, the lower brake 30 exerts the braking force, and when the lower motor 26 is providing the driving force, the upper brake 22 exerts the braking force. The tension at the time of traveling of the sheet-shaped member 10 can be made appropriate, and the sheet-shaped member 10 can be prevented from waving.

(B) Second Embodiment Next, a second embodiment of the opening device and the flexible member exercising device according to the present invention will be briefly described with reference to the drawings.

FIG. 9 is a block diagram showing the electrical configuration of the opening device of the second embodiment. The same or corresponding portions as those in FIG. 8 showing the electrical configuration of the first embodiment are provided. The same reference numerals are given.

The opening device 1A according to the second embodiment has a different power supply configuration from the opening device 1 according to the first embodiment, and the mechanical configuration shown in FIGS. The configuration is the same as that of the first embodiment, and the electrical configuration other than the power supply configuration is also the same as that of the first embodiment.

That is, the opening device 1 of the second embodiment
A includes a natural energy / electric energy conversion unit 120, and receives electric energy from the natural energy / electric energy conversion unit 120 via a power stabilization circuit 121.
It is supplied to each part.

Natural energy / electric energy conversion unit 1
Examples of 20 include a solar cell, a wind power generator, and a hydraulic power generator. If the natural energy / electrical energy converter 120 is a solar cell, it is provided, for example, outdoors near the sash 3, on a roof, or on an independent outdoors. If the natural energy / electrical energy converter 120 is a wind power generator, it is provided, for example, outdoors or on the roof near the sash 3 or on an independent outdoors. If the natural energy / electrical energy conversion unit 120 is a hydroelectric generator, for example, the natural energy / electrical energy conversion unit 120 may be provided together with the rainwater flow path mechanism on the roof near the sash 3 or on the roof, or provided independently on the outside.

The power supply stabilization circuit 121 has a power storage function therein, and is provided with a natural energy / electric energy conversion unit 12.
By adjusting the amount of electric energy from zero, power is stably supplied to each unit.

According to the opening device 1A of the second embodiment, the same effects as those of the first embodiment can be obtained. In addition to this, according to the opening device 1A of the second embodiment, it is possible to technically respond to the energy saving demand of society.

When stable power supply cannot always be performed with only the electric energy from the natural energy / electrical energy converter 120, a commercial power supply or a storage battery may be used. In this case, it is necessary to provide a configuration in the power supply stabilizing circuit 121 that monitors the amount of stored electric energy from the natural energy / electrical energy conversion unit 120 and switches the power supply according to the amount.

(C) Third Embodiment Next, a third embodiment of the opening device and the flexible member exercising device according to the present invention will be briefly described with reference to the drawings.

FIG. 10 shows an opening device 1 according to the third embodiment.
FIG. 2B is a schematic diagram illustrating a configuration of a main part of B, in which the same and corresponding parts as those in the above-described drawings according to the first embodiment are denoted by the same reference numerals.

The opening device 1B according to the third embodiment is similar to the device shown in FIG.
As shown in FIG.
10 (indicated by 10-1 and 10-2 respectively in FIG. 10), and each sheet-shaped member 10-1,
The configuration for moving the 10-2 is also provided in two layers.

That is, the two upper winding shafts 11-1 and 11-1
1-2, two lower winding shafts 12-1, 12-2, two upper guide rollers 13-1, 13-2, two lower guide rollers 14-1, 14-2, 2 Upper motors 18-
1, 18-2 (omitted in FIG. 10), two lower motors 2
6-1 and 26-2 (omitted in FIG. 10), two upper brakes 22-1 and 22-2 (omitted in FIG. 10), and two lower brakes 30-1 and 30-2 (in FIG. 10). (Omitted).

Here, a total of four motors 18-1 and 18-
2, 26-1 and 26-2 are all provided on the same side, and a stable position in the width direction that prevents skew or meandering of the first sheet member 10-1, and a second sheet member The stable position in the width direction where the skew and meandering of the sheet member 10-2 is prevented is correctly overlapped.

The sheet members 10-1, 10-2
The control method for sending the shielding function area for each of the above is the same as in the first embodiment.

According to the opening device 1B of the third embodiment, substantially the same effects as those of the first embodiment can be obtained. Here, in the case of the opening device 1B of the third embodiment, since the sheet-shaped members are provided in two layers, two shielding functions (the same may be the same) can be exhibited. It also has an effect.

For example, if the first shielding function area that shields the opening 2 is a screen door and the second shielding function area is a lace cloth, it is possible to achieve an insect repellent function, a ventilation function, and a weak light shielding function. it can. The same function can be exerted by applying a lace cloth when the sheet-like member is single, but in the case of the lace cloth, insects may lay eggs on the lace cloth. Can be prevented.

It is to be noted that not only a double sheet but also a sheet
Needless to say, it may be necessary to provide more than weight.

As a modified embodiment of the third embodiment, the embodiment shown in FIG. 11 can be mentioned.

That is, an endless sheet-like member 10 is applied, and the sheet-like member 10 is looped over the upper main shaft 11A and the lower main shaft 12A, so that the two shielding functional regions are doubled in the opening 2A. It may be located at the shielding position.

In the apparatus shown in FIG. 11, only one of the main shafts (for example, 11A) can be used as the drive shaft. Further, depending on the running direction of the sheet-like member 10, the main shafts that become the driving force are controlled by the main shafts 11A and 11B. You can also switch.
In the latter case, for the reason described in the first embodiment, the end to which the driving force is applied by the main shaft 11A and the end to which the driving force is applied by the main shaft 11B are connected to the sheet-like member 10. And the same side when viewed from the width direction.

(D) Other Embodiments In the description of each of the above embodiments, various modified embodiments have been referred to, but further modified embodiments as exemplified below can be cited.

(D-1) In each of the above embodiments,
Although the sheet-like member shields almost the entire opening, the shielding area is not limited to this.

For example, as shown in FIG. 12, a sash (device) 130 is
And a sash lower frame 133, in which two upper and lower sash glasses (not shown) are mounted, only one of the upper and lower sash glass portions (the upper side in FIG. 12) is used as the opening device of the present invention. You may make it shield at 134.

As described above, even if the opening is not clearly divided into two or more, a part of the opening may be shielded.

Even when a part of the opening is shielded, the object to be shielded is called “opening” in the claims.

(D-2) In each of the above embodiments,
The movement of the sheet-shaped member is performed in units of the shielding function area,
Although only one of the shielding function areas is shown at the position where the opening is shielded, a part (or a plurality of shielding function areas) of a plurality of shielding function areas is arranged vertically to shield. There may be.

For example, as shown in FIG. 13, the upper half of the opening is shielded by the lower half of the mesh (shielding area) 140 and the lower half of the opening is shielded by the light shielding sheet (shielding area) 1.
It is also possible to make it possible to shield the upper half 41. For example, in a case where the eaves 142 are located outdoors, when the light blocking function and the insect repelling, ventilation, and ventilation functions are simultaneously performed, the shielding state in FIG. 13 is effective. In this case, a mark can be added to the sheet-like member to enable position management in units of half the length of the shielding function area, and up and down movements are possible in half units of the shielding function area And

In addition, the opening may be shielded by a combination of arbitrary portions of two shielding function areas instead of half of the shielding function area as shown in FIG. For example, the operation unit is provided with an arbitrary upward movement key or an arbitrary downward movement key that is moved up or down only during the operation period, and the sheet-shaped member is operated only during a period in which the arbitrary upward movement key or the arbitrary downward movement key is operated. The opening may be shielded by moving the sheet-like member at the time of completion of the operation.

Further, as one shielding function area (as the shielding function area itself), areas having different shielding functions in the upper and lower portions as shown in FIG. 13 may be provided in the sheet-like member.

(D-3) The function of the shielding function area in the sheet-like member as the opening device is arbitrary. For example, fire prevention, waterproofing, windproofing, crime prevention, bulletproofing, shading, sound insulation, heat insulation, sunshading, rainproofing, blindfolding, taking in diffused sunlight, providing background images (including bulletin boards), describing and erasing. Functions such as a blackboard, a projector and a slide screen.

The material of each shielding function area in the sheet member is also optional. For example, cloth (light-shielding type, fire protection using silica cloth, waterproofing type, etc.), net (for insect repellent, sunshade, etc.), paper (shoji paper, etc.), steel net (blindfold, bulletproof, sunshade, etc.) , Steel plates (for crime prevention, fire prevention, etc.), and pipes (pipes arranged side by side to form a sheet (blindness); crime prevention, fire prevention, etc.). Further, a slat-like shutter may be used.

The configuration of the sheet-like member is not limited to that shown in FIG. 6, but may be any as long as the shielding function areas are provided in parallel. For example, as shown in FIG. 14, a plurality of strings 152 are connected to a pair of wires 150 and 151 in a ladder shape, and a plurality of shielding function unit sheets 153 (FIG. 14 Examples of “net”, “blindfold” and “transparent sheet” may be attached. In the example of FIG. 14, the lowermost shielding area in the drawing is made of slats, and the slats are directly attached to the pair of wires 150 and 151.

Even when a steel net, steel plate, pipe or the like is made of a material, it is necessary to have flexibility as a whole. Therefore, in the claims, the expression “flexible member” is applied.

Further, the attachment of each shielding function area to the sheet base may be any of adhesion, welding, sewing, insertion, and the like. Alternatively, a sheet portion for each shielding function area may be prepared, and the sheet portions may be completed by directly connecting them.

(D-4) In each of the above embodiments,
Although the sheet-like member (therefore, the opening device) is provided on the indoor side, the present invention is not limited to this. For example, a sheet-like member may be provided on the outdoor side. Further, for example, if the sash device has a double sash configuration, a portion of a sheet-like member exhibiting a shielding function may be passed between the double sashes. A portion of the sheet-like member exhibiting a shielding function may be passed between the multilayer glasses.

(D-5) In each of the above embodiments,
Although the sheet-like member at the position for shielding the opening is not protected at all, the sheet-like member may be covered with a cover such as transparent glass. That is, the sheet-like member at the position where the opening is shielded may be contained in the case.

Here, if the lid rotates about an axis provided at one end or slides, the end of the lid at which the lid starts to open is moved by the drive motor. It is preferable to make it the side to be made. As described above, since the sheet-like member slightly slides on the side on which the motor is provided, maintenance and inspection of the motor is more important than that of the brake.

(D-6) In each of the above embodiments,
In order to drive one sheet-like member, the one provided with a motor on each of the upper and lower sides is shown, but one motor is provided,
The driving force of the motor may be transmitted to one of the upper winding shaft and the lower winding shaft by a clutch, a movement transmitting mechanism, or the like. It should be noted that “first
The “drive source” and “second drive source” include this case.

[0139] Even in this case, it is preferable that the ends of the upper winding shaft and the lower winding shaft to which the driving force is transmitted be on the same side.

Similarly, one brake may be selectively operated with respect to the upper winding shaft and the lower winding shaft. The “first braking mechanism” and the “second braking mechanism” in the claims include this case.

(D-7) In each of the embodiments described above, the sheet-like member is not provided with the shielding function region exhibiting the exact same shielding function. However, the shielding function region exhibiting the identical shielding function is not provided. A plurality of functional regions may be provided.

For example, when the number of shielding function areas of the sheet-like member is large, a plurality of shielding function areas which are considered to be frequently selected may be provided so that the time required for moving to the shielding function area can be shortened. .

(D-8) In each of the above embodiments, the sheet-like member is not completely changed once the sheet-like member is completed. However, the function addition or deletion of the shield function area is performed. May be made so as to be able to cope with a partial change accompanying the above, or a partial replacement due to breakage or damage. Referring to FIG. 6 described above as an example, a light-shielding sheet 70-1, a shoji paper 70-2, and a net 70-3 as a light-shielding function area
And the like are detachably attached to the main body of the sheet-shaped member 10 by a detachable member such as a fastener so that the shielding function area of the sheet-shaped member 10 can be partially changed or partially replaced. Is also good. The same applies to FIG. 14 described above.

(D-9) In each of the above embodiments,
Although the upper motor and the lower motor have a built-in brake mechanism (lock mechanism), a motor without a brake mechanism (lock mechanism) may be applied.

That is, since the upper winding shaft and the lower winding shaft are each connected to a brake, the braking force of these brakes is used to stop the upper winding during the period when the sheet member is stopped. Unnecessary rotation of the take-up shaft and the lower take-up shaft may be prevented.

(D-10) In each of the above embodiments, only the braking force of the lower brake is changed during the upward movement period, and only the braking force of the upper brake is changed during the downward movement period. However, the braking force of the upper and lower brakes may be changed during the upward movement period and the downward movement period.

A description will be given of an upward movement as an example. For example, a change in the speed at the time of the initial acceleration of the upward motion is given to the upper motor, and a drive signal for achieving the speed at the constant speed traveling at the time of stability is given. May be gradually reduced to obtain an initial desired change during acceleration. Also, for example, at the time of deceleration before stopping in upward movement, not only the lower brake but also the braking force of the upper brake may be applied to obtain a desired change during deceleration.
In this case, it is preferable to increase the braking force of the lower brake so as to prevent the tension of the sheet-shaped member from becoming too loose.

The upper brake and the lower brake intended to adjust the tension of the sheet-like member apply a braking force to the corresponding upper winding shaft and lower winding shaft. May be applied to apply a braking force to the vehicle to adjust the tension of the sheet-shaped member during traveling. For example, each of the upper and lower guide rollers of the first embodiment is replaced by a set of two guide rollers provided so as to sandwich the sheet-like member, and here (for example, on one roller) May be applied.

(D-11) In the above embodiments, guide rollers are provided above and below, but these guide rollers may be omitted.

Conversely, between the upper and lower guide rollers,
It may have one or more guide rollers. In this case, the portion of the sheet-like member between the upper and lower guide rollers does not have to be on the same plane.

(D-12) In each of the above embodiments, the operation unit for instructing the movement of the sheet-like member is connected to the control unit by wire, but a remote control system may be applied. good.

(D-13) In each of the above embodiments, the case where the sheet-like member is moved by a predetermined amount when an operation is performed on the operation unit has been described. However, an automatic movement function may be introduced. good.

For example, when a plurality of shielding function areas for providing different background images are continuously provided on the sheet-like member, each shielding function area is kept for a predetermined time (for example, 30 seconds).
If it is stopped only for a minute), it may be automatically moved to the next position of the shielding function area.

(D-14) In each of the above embodiments, the position management of the shielding function area is performed by the output from the photoelectric sensor. However, it is needless to say that other methods may be used. For example, if a stepping motor is used as the motor, the position of the shielding function area may be managed by the number of pulses for driving the stepping motor. Further, a rotary encoder may be provided on the upper and / or lower winding shaft, and the position of the shielding function area may be managed by the output. Further, the position of the sheet-like member is detected by a mechanical position detection configuration such as a limit switch (in this case, a through-hole or a protruding piece is required at the end in the width direction of the sheet-like member), and the shielding function area May be managed.

(D-15) In each of the above embodiments, the abnormality monitoring during running of the sheet-like member is monitored by the time from the start or the like. However, instead of this, or in addition to this, Other methods may be applied. For example, a tension sensor (for example, a tension sensor that detects the tension of a portion of the sheet-shaped member at a position where the opening is blocked)
A tension roller may be provided to monitor the occurrence of an abnormality by the tension.

(D-16) In each of the above embodiments, the traveling direction of the sheet-like member is shown as being up and down.
The direction may be a horizontal direction or a horizontal direction (parallel to the ground), or may be an oblique direction (for example, applied to a skylight).

Further, the vehicle may travel along a curved surface. For example, many buildings in which the outer wall is curved and the window is curved have recently appeared, and the sheet-shaped member may be caused to travel along the curved surface of such a curved window. In this case, a guide roller is required at an appropriate position.

(D-17) In each of the above embodiments, the opening device for the window-like opening has been described.
The type of the opening is not limited to this, and may be a roof or a door.

For example, it may be a terrace, a carport, or an arcade roof. In the case of these roofs, it is not an opening through which an object can pass, but an opening through which an object can pass may be provided, and the opening device of the present invention may be provided. An opening device may be provided. In the latter case, the roof itself is not an opening through which objects can pass, but it is an optical opening, and the openings of the present invention are intended to include such openings.

The opening targeted by the present invention is not limited to an opening for a building, but may be, for example, an opening for a ship or a vehicle.

(D-18) The flexible member exercising device of the present invention is intended to be applied to an opening device, but requires a reciprocating motion of the flexible member. Alternatively, the present invention can be applied to another portable device.

Even when the flexible member exercising device of the present invention is applied to a device other than the opening device, each of the above-described embodiments (including modified embodiments) is the same as that applied to the opening device. Can be applied as it is. For example,
A solar cell can be used as a power source.

[0163]

According to the opening device of the present invention, many shielding functions can be provided even with one device.

Further, according to the flexible member exercising device of the present invention, the flexible member can run without meandering, skewing or waving.
