JP 2001-301465 A

  When the shade opening / closing direction length of the shade opening is large, if the structure that covers the shade opening / closing with only one roll is used, the length of the shade becomes longer, and the center of the shade tends to loosen when the shade is closed. When the shade is opened, there is a problem that the roll storage space increases because the roll winding diameter of the roll increases. In such a case, a structure in which a plurality of rolls are arranged and the shade is divided as in Patent Document 1 is advantageous.

  However, in the structure described in Patent Document 1, since the roll is disposed so as not to move in the middle of the shade opening, the roll and the horizontal beam covering the roll always exist in the shade opening. There is a problem of lack of openness when fully opened. In addition, since each shade has a structure that opens and closes independently, there is a problem that a plurality of motors are required to drive each shade when it is electrically driven.

  The present invention has been created to solve such a problem. In a roll shade device having a plurality of rolls, there is no obstacle such as a lateral beam in the opening of the shade, and a plurality of one drive source can be used. An object of the present invention is to provide a roll shade device capable of opening and closing the shade.

In order to solve the above-described problems, a roll shade device according to the present invention includes a proximal shade, a proximal roll connected to one end of the proximal shade to unwind and wind the proximal shade, and the proximal shade. A movable shade disposed adjacent to the movable shade, connected to one end of the movable shade, unwinding and winding the movable shade, movable along the shade opening / closing direction, and other than the proximal shade A connecting member for connecting the end and the rotation support shaft of the moving roll, a driving means for driving the other end of the moving shade along the shade opening / closing direction, and the base end roll is always urged to rotate in the winding direction. A proximal roll urging means; and a moving roll urging means for constantly urging the moving roll in the winding direction. When the shade is closed, the driving means is driven in the shade closing direction. The moving shade is unwound against the urging force of the moving roll urging means, and the proximal shade is urged by the proximal roll urging means as the moving roll moves in the shade closing direction. When the shade is opened, the drive means is driven in the shade opening direction, the moving shade is wound by the urging force of the moving roll urging means, and the moving roll is moved in the shade opening direction. The base end shade is wound by the urging force of the base end roll urging means, and the rotating support shaft of the moving roll and the rotating support shaft of the base end roll are orthogonal to the shade deployment surface. It is configured to be displaceable in the direction, and the moving support shaft and the rotating shaft of the base roll are displaced in a direction perpendicular to the shade development surface, thereby moving the moving roller. Edo and each shade deploying surface of the proximal shade is characterized by being configured so as to be parallel to the shade opening and closing direction.

According to the present invention, since the moving roll is movable in the shade opening and closing direction, there is a roll and a horizontal beam covering the roll in the middle of the shade opening when the shade is opened as in Patent Document 1. There is no. Therefore, the roll shade device is excellent in a feeling of opening when the shade is opened.
Further, since the proximal shade is unwound and wound in conjunction with the movement of the moving roll, each moving shade and proximal shade can be unwound and wound with a single drive source. It becomes a typical roll shade device.
According to the present invention, both development surfaces of the moving shade and the base end shade are connected in a flush manner, and the appearance of the shade is improved.

  In the roll shade device of the present invention, a plurality of movable roll units each including the movable shade, the movable roll, and the movable roll urging means are arranged in a shade opening / closing direction, and are positioned closer to the proximal end roll. The other end of the moving shade of the first moving roll unit to be connected to the rotating support shaft of the moving roll of the second moving roll unit adjacent to the first moving roll unit is connected by a moving roll connecting member. It is characterized by.

  According to the present invention, even if the shade opening direction length of the shade opening is large, the roll shade device can be easily handled.

  In the roll shade device according to the present invention, the rotation support shaft of the moving roll engages with a long hole formed in the connection member, and the rotation support shaft of the moving roll is displaced in a direction orthogonal to the shade deployment surface. Accordingly, the rotation support shaft of the moving roll moves in the elongated hole, so that the gap between the moving shade and the front end of the base end shade is maintained constant. It is characterized by that.

  According to the present invention, light leakage from the shade gap can be reduced with a simple structure.

  According to the present invention, an economical roll shade device that is excellent in a feeling of opening when the shade is opened and that can open and close a plurality of shades with a single drive source.

“First Embodiment”
In FIG. 1 (a), a sunroom 71 is formed surrounded by a wall 72 of a house, a glass-covered top plate 73, and side plates 74. The top plate 73 is inclined downward as it goes from the wall 72 to the side plate 74, for example. The roll shade device 1 is disposed below the top plate 73 so as to perform light collection and light shielding from the top plate 73.

The moving shade 4 disposed adjacent to the base shade 2 and the rear end (one end) of the moving shade 4 are connected to unwind and wind the moving shade 4 and move along the shade opening / closing direction S. The movable roll 5, the connecting member 7 that connects the front end (other end) of the base end shade 2 and the rotation support shaft 6 of the movable roll 5, and the front end (other end) of the movable shade 4 in the shade opening / closing direction S Driving means 8 for driving along, proximal end roll urging means 9 for always urging the proximal end roll 3 in the winding direction Q1, and moving roll for always urging the moving roll 5 in the winding direction Q2. And a force means 10.

"Guide rail 11"
As shown in FIG. 2, the guide rail 11 is attached to the wall body 72 via a cross beam 75. The guide rail 11 is a member that guides the shade opening / closing operation of the base end shade 2 and the moving shade 4 and the movement of the moving roll 5. The guide rail 11 has a rear end attached to a fixing portion 75A of the cross beam 75 and extends toward the side plate 74 along the top plate 73 shown in FIG. 1, and a front end thereof is attached to a fixing portion (not shown). The guide rails 11 are provided as a pair on both sides of the base shade 2 and the moving shade 4. The guide rail 11 is made of, for example, an extrusion mold material made of an aluminum alloy. FIG. 2 shows a mode in which a plurality of roll shade devices 1 are arranged in parallel in the left-right direction in accordance with the width specification of the sunroom 71. As shown in FIG. 3 and the like, for example, a decorative plate 76 is attached to the lower portion of the guide rail 11.

  As shown in FIG. 4, a roll guide groove 31 that guides the movement of the rotary spindle 6 of the moving roll 5 in the shade opening / closing direction S, the shoe 25 of the proximal shade 2, and the moving shade are provided on the side surface of the guide rail 11. A shoe guide groove 32 for guiding the four shoes 26 and a cable groove 33 for inserting a push-pull cable 27 described later are formed.

  As shown in FIGS. 3 and 5, a guide member 34 that guides the vertical displacement of the base end roll 3 and the moving roll 5 is attached to the guide rail 11. The guide member 34 is a member having an elongated rectangular parallelepiped shape in the extending direction of the guide rail 11, and is formed by cutting out a part of the groove plate 35 constituting the roll guide groove 31 of the guide rail 11. It is fitted and fixed to the portion 36. A first support shaft moving groove 37 extending in the direction T (hereinafter simply referred to as direction T) with respect to the shade development surface is formed on the rear side of the guide member 34, and on the front side, on the front side (shade). A second support shaft moving groove 38 is formed which is displaced downward in the direction of the closing direction and whose lower end communicates with the roll guide groove 31.

"Base end roll 3"
1 and 2, the base end roll 3 includes a cylindrical roll cylinder 12 that winds the base end shade 2 around the circumferential surface, and a rotation support shaft 13 that is positioned on the axis of the roll cylinder 12. Configured. A torsion coil spring 18 is interposed between the roll cylinder 12 and the rotary support shaft 13 as the base end roll urging means 9 in a twisted state. That is, the roll cylinder 12 is configured to be relatively rotatable with respect to the rotation support shaft 13 via the torsion coil spring 18. The torsion coil springs 18 are arranged as a pair inside both ends of the roll cylinder 12, one end being locked to the inner peripheral surface of the roll cylinder 12, and the other end being locked to the rotation support shaft 13. .

  The rotation support shaft 13 is configured to be movable in the shade opening / closing direction S and displaceable in the direction T by being engaged with and guided by the first support shaft moving groove 37 described above. The reason why the rotation support shaft 13 is displaceable in the direction T is that the base shade 2 unrolled and unfolded due to a change in the winding diameter of the base end shade 2 in the roll cylinder 12 is inclined with respect to the shade opening / closing direction S. This is to correct the problem. That is, if the rotation support shaft 13 is configured to be undisplaceable in the direction T, the winding diameter of the roll cylinder 12 decreases as the proximal shade 2 is unwound. On the other hand, the rear end of the base end shade 2 is deployed with an upward slope, leading to poor appearance. On the other hand, in this embodiment, when the base end shade 2 is unwound from the roll cylinder 12, the rotation support shaft 13 is guided by the first support shaft moving groove 37, and the shade development surface within the direction T is obtained. It is configured to be displaced in a direction T1 approaching (hereinafter referred to as an orthogonal proximity direction T1 with the shade development surface). Thereby, the developed proximal shade 2 is parallel to the shade opening / closing direction S, and the developed proximal shade 2 looks good.

  As shown in FIG. 5, collars 15 having flat portions 15 </ b> A and 15 </ b> A formed on the peripheral surface are axially attached to both ends of the rotation support shaft 13. The flat portions 15A and 15A slide so as to face the inner surface of the first support shaft moving groove 37. As a result, the rotation support shaft 13 becomes a stator attached to the guide member 34 so as not to rotate around its axis, and the urging force of the torsion coil spring 14 is applied to the roll cylinder 12 which is the rotor.

  The vertical movement of the rotary support shaft 13 is performed by using, for example, the weight drop of the base end roll 3. As shown in FIG. 1, the base end roll 3 is disposed so that the base end shade 2 in a wound state is placed on the fixing portion 75 </ b> A of the cross beam 75. When the base end shade 2 is unwound and the winding diameter is reduced, the rotation support shaft 13 is lowered by the self-weight of the base end roll 3, and the base end shade 2 is wound up to increase the winding diameter. Then, the rotation support shaft 13 is raised by being pushed upward from the fixed portion 75A.

  When the first support shaft moving groove 37 is formed along the direction T as in the present embodiment, the rotating support shaft 13 is smoothly weighted due to friction between the collar 15 and the groove inner surface of the first support shaft moving groove 37. It may not be possible to fall. In this case, for example, the lower end of the first support shaft moving groove 37 is displaced more forward than the upper end in the shade opening / closing direction S (for example, the first support shaft moving groove 37 extends in the vertical direction in FIG. 1). ) What is necessary is just to form. In this case, with the winding and unwinding of the base end shade 2, the base end roll 3 moves in the shade opening / closing direction S by the amount of the displacement.

  As shown in FIGS. 1 and 5, the periphery of the front end of the base end shade 2 is supported by a holder 20. The holder 20 is a long member that is substantially the same as the width of the proximal shade 2, and has a top surface portion 20A, a rear surface portion 20B, and a bottom surface portion 20C. It has an almost U shape. The front end of the base end shade 2 is formed into a bag shape by folding back and the like, and a core bar 21 is inserted inside. The periphery of the front end of the base end shade 2 is folded back so as to go into the holder 20 from the lower surface portion 20 </ b> C side, and then fixed to the holder 20 by the stopper member 22. The stop member 22 is locked to, for example, a claw portion formed on the upper surface portion 20A. The front end of the stop member 22 always abuts against the peripheral surface of the movable shade 4 wound around the movable roll 5 regardless of the winding diameter by the cam action of the long hole 24 of the connecting member 7 described later. It is like that.

"Moving roll 5"
In FIG. 1 and FIG. 2, the moving roll 5 includes a cylindrical roll cylinder 16 that winds the moving shade 4 around the circumferential surface, and a rotating support shaft 6 that is positioned on the axis of the roll cylinder 16. Has been. A torsion coil spring 18 is interposed between the roll cylinder 16 and the rotary spindle 6 as the moving roll biasing means 10 in a twisted state. That is, the roll cylinder 16 is configured to be relatively rotatable with respect to the rotation support shaft 6 via the torsion coil spring 18. The torsion coil springs 18 are arranged as a pair inside the both ends of the roll cylinder 16, and one end is locked to the inner peripheral surface of the roll cylinder 16 and the other end is locked to the rotary spindle 6. . These moving rolls 5 have the same structure as that of the proximal roll 3.

The rotating support shaft 6 is movable in the shade opening / closing direction S and displaced in the direction T by being engaged with and guided by the second support shaft moving groove 38 of the guide member 34 and the roll guide groove 31 of the guide rail 11. It is configured to be possible. The reason for displacing the rotating support shaft 6 in the direction T is the same as in the case of the base end roll 3, and the unfolded moving shade 4 is shaded in accordance with the change in the winding diameter of the moving shade 4 in the roll cylinder 16. This is to make it parallel to the opening / closing direction S.
The rotation support shaft 6 and the rotation support shaft 13 do not need to be moved along the direction T, and may be moved with displacement in the direction T like the second support shaft movement groove 38 described above.

As shown in FIG. 5, collars 19 having flat portions 19 </ b> A and 19 </ b> A formed on the peripheral surface are axially attached to both ends of the rotation support shaft 6. The flat portions 19A and 19A slide so as to face the inner surfaces of the second support shaft moving groove 38 and the roll guide groove 31. As a result, the rotation support shaft 6 becomes a stator attached to the guide member 34 and the guide rail 11 so that the rotation support shaft 6 cannot rotate around its axis, and the urging force of the torsion coil spring 18 is applied to the roll cylinder 16 which is the rotor.
Further, the periphery of the front end of the movable shade 4 is also supported by a holder 23 similar to the holder 20 on the proximal shade 2 side. At both ends of the holder 23, shoes 26 that slide in the shoe guide grooves 32 of the guide rail 11 are formed. The shoe 26 may be integrally formed with the holder 23.

"Connecting member 7"
In FIG. 5, the connecting member 7 is provided on both sides of the holder 20 so as to be integrated with the holder 20. The connecting member 7 and the holder 20 may be formed by integral molding. The connecting member 7 is formed with a long hole 24 for penetrating and locking the rotary spindle 6 of the moving roll 5. The long hole 24 functions as a relief hole that absorbs the amount of displacement when the rotation support shaft 6 slides in the second support shaft moving groove 38 and is displaced in the T direction. Further, in the present embodiment, the long hole 24 is formed in an inclined shape so that the lower end is displaced rearward in the shade opening / closing direction S rather than the upper end, as can be seen from FIG. This is to change the relative position of the rotary spindle 6 and the connecting member 7 in the shade opening / closing direction S even when the rotary spindle 6 is displaced in the direction T and the winding diameter of the moving roll 5 is changed. This is because the gap U formed between the movable shade 4 and the vicinity of the front end of the proximal shade 2 is kept constant. The connecting member 7 is formed with a shoe 25 that slides in the shoe guide groove 32 of the guide rail 11.

“Drive 8”
The drive means 8 includes a push-pull cable 27 (FIG. 3) that is inserted into the cable groove 33 of the guide rail 11 and has a tip connected to the holder 23, and a motor 28 (FIG. 1) that drives the push-pull cable 27. Has been. The motor 28 is placed on the fixed portion 75 </ b> A of the cross beam 75. The push-pull cable 27 and the holder 23 are connected via a shoe 26, for example.

"Action"
The operation of the roll shade device 1 will be described mainly with reference to FIG. First, the operation when the shade is closed will be described. FIG. 6A shows a state in which the base end shade 2 and the moving shade 4 are wound up to the maximum by the base end roll 3 and the moving roll 5, respectively, and the shade opening is fully opened. In this state, the rotation support shaft 13 of the proximal roll 3 is located at the upper end of the first support shaft movement groove 37, and the rotation support shaft 6 of the movement roll 5 is located at the upper end of the second support shaft movement groove 38. . Further, the rotation support shaft 6 is located at the upper end of the long hole 24 of the connection member 7.

  When the motor 28 is driven, the holder 23 moves forward via the push-pull cable 27, and as shown in FIG. 6B, the movable roll 5 is pulled forward so that the rotary spindle 6 moves through the second spindle moving groove 38. The moving shade 4 is unwound from the moving roll 5 against the urging force of the torsion coil spring 18 while descending. When the rotating support shaft 6 moves down the second support shaft moving groove 38, that is, when the rotating support shaft 6 is displaced in the direction T1 perpendicular to the shade development surface, the rotating support shaft 6 moves in the long hole 24 accordingly. Then, the connecting member 7 is pulled forward by the cam action, so that the front end of the stop member 22 (FIG. 1) always keeps a light contact with the peripheral surface of the movable shade 4. Therefore, the gap U is kept constant. The unfolded moving shade 4 is parallel to the shade opening / closing direction S. When the movable shade 4 is unwound to the maximum, the rotating support shaft 6 is positioned at the lower end of the second support shaft moving groove 38 as shown in FIG. Further, the rotation support shaft 6 is located at the lower end of the long hole 24 as well.

  When the holder 23 further moves forward from the state of FIG. 6C, the movable roll 5 moves forward by the rotation support shaft 6 moving in the roll guide groove 31 of the guide rail 11. The proximal end shade 2 is unwound from the proximal end roll 3 by pulling the front end of the proximal end shade 2 through the connecting member 7 by the advance of the moving roll 5. As shown in FIG. 6 (d), in the state where the base end shade 2 is unwound to the maximum, the rotation support shaft 13 of the base end roll 3 is moved by the weight of the base end roll 3 and further by the tension of the base end shade 2. The first support shaft moving groove 37 is displaced to the lower end. As a result, the deployed proximal shade 2 is parallel to the shade opening / closing direction S.

  Next, the operation when the shade is opened will be described. 6D, when the motor 28 is driven in the reverse direction, the holder 23 moves backward via the push-pull cable 27. Since the front end of the stop member 22 (FIG. 1) is in contact with the peripheral surface of the movable shade 4, the rotation support shaft 6 is displaced in the direction T2 away from the shade development surface (the orthogonal separation direction T2 with the shade development surface). As long as the rotation support shaft 6 does not move up the long hole 24, the stop member 22 has a function of regulating the winding of the movable shade 4. Therefore, when the holder 23 moves backward, the movable shade 4 is maintained in the substantially unfolded state, and the proximal end shade 2 is moved to the proximal end roll by the biasing force of the torsion coil spring 18 of the proximal end roll biasing means 9 of the proximal end roll 3. It is rolled up by three. As shown in FIG. 6 (c), when the winding diameter of the proximal shade 2 at the proximal roll 3 is increased, the lower end of the peripheral surface of the proximal shade 2 is fixed to a fixing portion 75A of the horizontal beam 75 (FIG. 1). Is pushed upward from above, the rotation support shaft 13 of the base end roll 3 rises in the first support shaft movement groove 37 and is positioned at the upper end. The rotating support shaft 6 of the moving roll 5 is located at the lower end of the second support shaft moving groove 38.

  When the rotation support shaft 6 of the moving roll 5 is positioned at the lower end of the second support shaft moving groove 38, the force of winding the moving shade 4 by the biasing force of the torsion coil spring 18 of the moving roll biasing means 10 causes the stop member 22 to be wound. Since it acts as a force that pushes backward, the force that pushes the stopper member 22 backward acts as a force that raises the rotary support shaft 6 in the long hole 24 and the second support shaft moving groove 38. As a result, the rotary support shaft 6 moves up the long hole 24 and the second support shaft moving groove 38, and the moving shade 4 is moved by the urging force of the torsion coil spring 18 of the moving roll urging means 10 of the moving roll 5. And then returns to the state of FIG. 6A through the state of FIG.

  As described above, the base end shade 2, the base end roll 3 connected to one end of the base end shade 2 to unwind and wind up the base end shade 2, and the base end shade 2 are disposed. The movable shade 4 is connected to one end of the movable shade 4 to unwind and wind up the movable shade 4, and can move along the shade opening / closing direction S. A connecting member 7 that connects the rotation support shaft 6 of the roll 5, a driving means 8 that drives the other end of the movable shade 4 along the shade opening / closing direction S, and the base end roll 3 that always rotates in the winding direction Q 1. A proximal roll urging means 9 for urging and a moving roll urging means 10 for constantly urging the moving roll 5 in the winding direction Q2; when the shade is closed, the driving means 8 is driven in the shade closing direction. , Moving shade 4 moves The base end shade 2 resists the urging force of the base end roll urging means 9 as the moving roll 5 moves in the shade closing direction. When the shade is opened, the driving means 8 is driven in the shade opening direction, the moving shade 4 is wound up by the urging force of the moving roll urging means 10, and the moving roll 5 is moved in the shade opening direction. Accordingly, if the base shade 2 is wound up by the urging force of the base end roll urging means 9, the following effects can be obtained.

(1) Since the moving roll 5 is configured to be movable in the shade opening / closing direction S, the roll does not exist in the middle of the opening of the shade when the shade is opened as in Patent Document 1. Therefore, it becomes the roll shade apparatus 1 excellent in the open feeling at the time of shade opening.
(2) Since the base shade 2 is unwound and wound in conjunction with the movement of the moving roll 5, each unwinding and winding of the moving shade 4 and the base shade 2 is performed by one drive source (motor 28), an economical roll shade device 1 is obtained.

  The rotation support shaft 6 of the moving roll 5 and the rotation support shaft 13 of the proximal end roll 3 are configured to be displaceable in the T direction, and the rotation support shaft 6 of the moving roll 5 and the rotation support shaft 13 of the proximal end roll 3 are shaded. If the shade development surfaces of the moving shade 4 and the base end shade 2 are arranged in parallel with the shade opening / closing direction S by displacing in the orthogonal proximity direction T1 with the development surface, the movement shade 4 and the base end shade 2 are configured. The two shade development surfaces are arranged in a single plane, and the appearance of the shade is improved.

  Further, the rotation support shaft 6 of the moving roll 5 is engaged with the elongated hole 24 formed in the connecting member 7, and the rotation support shaft 6 of the moving roll 5 is displaced in the direction T. If the shaft 6 moves in the long hole 24 and the gap U between the moving shade 4 and the front end of the base shade 2 is maintained constant, light from the gap U can be obtained with a simple structure. Leakage can be reduced.

“Second Embodiment”
A second embodiment will be described with reference to FIGS. When the unit configured to include the movable shade 4, the movable roll 5, and the movable roll urging means 10 in the first embodiment is referred to as a “movable roll unit”, the second embodiment defines the movable roll unit as a shade opening / closing direction. This relates to a configuration in which a plurality of S are arranged. Hereinafter, the moving roll unit positioned closer to the proximal roll 3 will be described as a first moving roll unit 41, and the moving roll unit adjacent to the front side of the first moving roll unit 41 will be described as a second moving roll unit 42. Further, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The first moving roll unit 41 and the second moving roll unit 42 have the same configuration. The front end (the other end) of the moving shade 4 of the first moving roll unit 41 and the rotating spindle 6 of the moving roll 5 of the second moving roll unit 42 are connected by a moving roll connecting member 43. The structure itself of the moving roll connecting member 43 is the same as that of the connecting member 7, and the difference is that the connecting member 7 connects the other end of the base shade 2 and the rotating spindle 6 of the moving roll 5, whereas the moving roll The connecting member 43 connects the other end of the moving shade 4 of one moving roll unit (first moving roll unit 41) and the rotating spindle 6 of the moving roll 5 of the other moving roll unit (second moving roll unit 42). Is to connect.

As shown in FIG. 9, the second support shaft moving groove 38 formed in the guide member 34 is lowered downward in the forward direction (shade closing direction) like the second support shaft moving groove 38 of the first embodiment. The inclined groove 38B is displaced and has a lower end communicating with the roll guide groove 31 and a horizontal groove 38A extending rearwardly along the shade opening / closing direction S from the upper end of the inclined groove 38B.
Further, the push-pull cable 27 (FIG. 3) is connected to the holder 23 attached to the front end of the second moving roll unit 42.

"Action"
The operation of the roll shade device 1 will be described mainly with reference to FIG. First, the operation when the shade is closed will be described. FIG. 10A shows a state in which the base end shade 2 and each moving shade 4 are wound up to the maximum by the base end roll 3 and each moving roll 5, respectively, and the shade opening is fully opened. In this state, the rotation support shaft 13 of the base end roll 3 is located at the upper end of the first support shaft moving groove 37, and the rotation support shaft 6 of the moving roll 5 of the first moving roll unit 41 is the second support shaft moving groove 38. The rotary support shaft 6 of the moving roll 5 of the second moving roll unit 42 is positioned at the front end of the horizontal groove 38A of the second supporting shaft moving groove 38. Further, the rotary support shaft 6 of the moving roll 5 of the first moving roll unit 41 is positioned at the upper end of the long hole 24 of the connecting member 7, and the rotary support shaft 6 of the moving roll 5 of the second moving roll unit 42 is connected to the moving roll. It is located at the upper end of the long hole 24 of the member 43.

  When the motor 28 is driven, the holder 23 of the second moving roll unit 42 moves forward via the push-pull cable 27, and the moving roll 5 of the second moving roll unit 42 is pulled forward as shown in FIG. 10B. Thus, the moving shade 4 is unwound from the moving roll 5 against the urging force of the torsion coil spring 18 while the rotating support shaft 6 descends the inclined groove portion 38B of the second support shaft moving groove 38. When the rotating support shaft 6 descends the inclined groove portion 38B of the second support shaft moving groove 38, that is, when the rotating support shaft 6 is displaced in the orthogonal proximity direction T1 with the shade development surface, the rotation support shaft 6 is moved accordingly. The front end of the stop member 22 (FIG. 1) moves around the movable shade 4 of the second movable roll unit 42 by moving in the long hole 24 of the connection member 43 and pulling the movable roll connection member 43 forward by a cam action. Maintain a light contact with the surface at all times. Therefore, the gap U is kept constant. The unfolded moving shade 4 is parallel to the shade opening / closing direction S. When the moving shade 4 of the second moving roll unit 42 is unwound to the maximum extent, as shown in FIG. 10C, the rotating support shaft 6 of the second moving roll unit 42 is moved to the second support moving groove 38. Located at the lower end of Further, the rotation support shaft 6 is located at the lower end also in the long hole 24 of the movable roll connecting member 43.

  When the holder 23 of the second moving roll unit 42 further advances from the state of FIG. 10C, the rotation supporting shaft 6 of the second moving roll unit 42 is guided by the roll guide groove 31 of the guide rail 11. To move forward. Then, the forward end of the second moving roll unit 42 pulls the front end of the moving shade 4 of the first moving roll unit 41 via the moving roll connecting member 43, so that the rotation support shaft 6 of the first moving roll unit 41 is moved. While moving forward in the horizontal groove portion 38A of the second support shaft moving groove 38, the inclined groove portion 38B is lowered. For the same reason as in the case of the second moving roll unit 42, the gap U between the moving shade 4 and the front end of the proximal shade 2 is kept constant, and the deployed moving shade 4 is parallel to the shade opening / closing direction S. . When the moving shade 4 of the first moving roll unit 41 is unwound to the maximum extent, as shown in FIG. 10 (d), the rotating support shaft 6 of the first moving roll unit 41 is the second support shaft moving groove 38. Located at the lower end of Further, the rotation support shaft 6 is located at the lower end also in the long hole 24 of the connection member 7.

  When the holder 23 of the second moving roll unit 42 further moves forward, the first moving roll unit 41 moves forward by the rotation support shaft 6 being guided by the roll guide groove 31 of the guide rail 11. The proximal end shade 2 is unwound from the proximal end roll 3 by pulling the front end of the proximal end shade 2 through the connecting member 7 by the advance of the first moving roll unit 41. As shown in FIG. 10 (e), in the state where the base end shade 2 is unwound to the maximum, the rotation support shaft 13 of the base end roll 3 is caused by the weight of the base end roll 3 and the tension of the base end shade 2. The first support shaft moving groove 37 is displaced to the lower end. As a result, the deployed proximal shade 2 is parallel to the shade opening / closing direction S.

  Next, the operation when the shade is opened will be described. When the motor 28 is driven in the reverse direction, the holder 23 of the second moving roll unit 42 moves backward via the push-pull cable 27. Since the front end of the stopping member 22 of the holder 23 of the first moving roll unit 41 is in contact with the peripheral surface of the moving shade 4 of the second moving roll unit 42, and the front end of the stopping member 22 of the holder 20 of the proximal end roll 3 Are in contact with the peripheral surface of the movable shade 4 of the first moving roll unit 41, so that the respective rotation support shafts 6 are displaced in the direction T2 perpendicular to the shade development surface, and the respective rotation support shafts 6 have the long holes 24. Unless it raises, the stop member 22 bears the function which regulates winding of each moving shade 4. Therefore, when the holder 23 of the second moving roll unit 42 moves backward, each moving shade 4 is maintained in a substantially unfolded state, and the proximal shade 2 is a torsion coil spring of the proximal roll urging means 9 of the proximal roll 3. The base end roll 3 is wound by the urging force of 18. As shown in FIG. 10 (d), when the winding diameter of the base end shade 2 at the base end roll 3 is increased, the lower end of the peripheral surface of the base end shade 2 is the fixed portion 75A of the cross beam 75 (FIG. 1). Is pushed upward from above, the rotation support shaft 13 of the base end roll 3 rises in the first support shaft movement groove 37 and is positioned at the upper end. The rotating support shaft 6 of the moving roll 5 is located at the lower end of the second support shaft moving groove 38.

  When the rotary support shaft 6 of the moving roll 5 of the first moving roll unit 41 is positioned at the lower end of the second support shaft moving groove 38, the rotary support shaft 6 is connected to the connecting member 7 for the same reason as in the first embodiment. The moving shade 4 is wound by the urging force of the torsion coil spring 18 of the moving roll urging means 10 while ascending the elongated hole 24 and the inclined groove portion 38 </ b> B of the second support shaft moving groove 38. Next, in the same manner, the second moving roll unit 42 has the rotating shade 6 ascending the elongated hole 24 of the moving roll connecting member 43 and the inclined groove portion 38B of the second supporting shaft moving groove 38, while the moving shade 4 has the moving roll. It is wound by the biasing force of the torsion coil spring 18 of the biasing means 10. As a result, the state returns to the state of FIG. 10A through the states of FIGS.

  As described above, if a plurality of moving roll units are arranged in the shade opening / closing direction S, the roll shade device 1 can be easily handled even when the shade opening / closing direction length of the shade opening is large.

  The preferred embodiment of the present invention has been described above. The present invention can be applied to a sunshade that opens and closes an opening formed in, for example, a vehicle roof in addition to a sunroom.
