  The present invention relates to a movable rod system, and more particularly, to a system having a light shelf (inner rod) that can be used for daylighting while reflecting direct light by tilting indoors.

  As this type of movable fence system, a large-area window is divided into an upper window and a lower window by a window bar installed in the middle in the vertical direction, and a rotary fence supported by a rotation fulcrum provided on the window frame. A system is known in which the amount of light collected from the upper window is adjusted (Patent Document 1).

  In the system of Patent Document 1, the range in which the amount of light can be adjusted is limited to the range of the upper window. For this reason, there is a problem that it is difficult for sufficient light to reach the interior of the room, and there has been a demand for a device that more actively performs daylighting in the interior of the room.

  Although it is not movable, it is a blind in which a large number of slats are arranged over the entire vertical length of the window in order to allow natural light to reach the interior of the room uniformly from the side of the window. One that gradually changes from horizontal to diagonally downward is known (Patent Document 2).

This lifting mechanism allows all or some of the movable rods to be released downward from the storage location, and can move one movable rod or a group of movable rods independently of the remaining movable rods,
Furthermore, each movable rod is tilted, and the posture can be maintained at a constant tilt angle.

  This means proposes a plurality of movable rods C that can be lifted and tilted along the inside of the wall 1 including the window (see FIGS. 1 and 2). By tilting the movable rod to near the horizontal, light can be taken into the back of the room, and by moving the movable rod close to the vertical, incidence of reflected light can be limited only near the window of the room. Moreover, the adjustment range of the lighting by such a movable rod can be adjusted by raising and lowering the movable rod. A light shielding unit may be provided below the lowest movable rod. As an installation method, in the preferred illustrated example, the movable rod is hangable with an appropriate number of connecting cords that respectively connect the lifting and lowering and tilting of the movable rod to the inner and outer parts of the movable rod. It can be changed as appropriate.

In the configuration of this means, “a movable rod or a group of movable rods can be lifted and lowered independently from the remaining movable rods” means that all of them can be moved together like slats constituting a blind.

Examples of the sliding means include those that always move in contact with the window and those that move up and down slightly away from the window and buffer the collision with the window when the movable rod is shaken.

The third means has second means, and the lifting mechanism has a pair of rotating bodies that rotate in accordance with the driving device for each movable rod, and is connected to each movable rod. The base end of the connecting string can be wound on one of the pair of rotating bodies, and the base end of the second connecting string connected to the movable rod can be wound on the other end of the pair of rotating bodies. Fixed to the
And about the movable rod which should be stored in a storage place, it shall be in the state where rotational force is not transmitted from a drive device to both rotating bodies corresponding to the movable rod.

The movable rods are connected to a plurality of second connecting strings suspended from a multi-stage rotating body having the same structure, and the lowermost movable rod of each group is earlier, the lower one is the upper one. While forming so as to move up and down late,
The outer portion and the inner portion of the movable rods other than the lowest in each group are connected in series with one first connecting string and one second connecting string, and between the movable rods. Each of the connecting string portions has a structure that can be elastically extended by a load of the movable rod.

In this means, as shown in FIG. 17, a plurality of movable rods C are divided into the same number of groups g ₁ , g ₂ ... Are operated by a pair of driving devices (a driving device for operating the outer portion of each movable rod and a driving device for operating the inner portion). Movable canopy C _A least significant of each group is connected by a plurality of connecting straps depending from multistage rotating member (non-stretchable). The movable rods other than the lowest are operated by one connecting string inside and outside, and the connecting string portion between each movable rod is a string portion B26 that can be extended by the load of the movable rod.

It is controlled so that the rotation speed ratio increases as the order of counting the ridges from the bottom decreases.

  In this means, as shown in FIG. 16, it is proposed to provide a main drive device B20 for raising and lowering a plurality of movable rods C and an auxiliary drive device B21 for tilting the movable rods C. Each of the driving devices incorporates clutch means in a power transmission path between the driving shaft of the driving device and the rotating shaft of the rotating body B3 linked to the connecting string of the movable rod C. The difference between the main drive device B20 and the auxiliary drive device B21 is that the former is linked to both of the two rotary bodies B3 associated with each movable rod C, whereas the latter is linked to one of the two rotary bodies B3. If you do it, it is enough. Further, a speed change means B22 is provided between the main drive device B20 and the two rotating bodies B3, and the rotational speed ratio becomes larger as the order counted from the bottom with respect to the movable rod C detached from the storage place becomes smaller. I am doing so. That is, the lower rotating body B3 descends faster.

  1 to 8 show a movable rod system A according to the first embodiment of the present invention. In addition, in FIG. 1, 1 is a wall body with a window part, 2 is a ceiling, 3 is a floor. This movable fence system is preferably constructed on the ceiling 2 side near the wall body W.

  FIG. 1 shows the overall configuration of the movable rod system A. The movable rod system A includes an elevating mechanism B, a plurality of movable rods C, a bag storage place D, a light shielding means E, and an operation unit F.

  Hereinafter, based on FIG. 1, the fundamental structure and function of a movable rod system are demonstrated.

  First, the elevating mechanism B has a driving device B1 formed by a motor or the like, and transmits rotational power from the driving device B1 to the rotating body B3 via the power shaft B2. In the present embodiment, a pair of rotating bodies B3 are provided for one movable rod C, and a driving device B1 and a power shaft B2 are provided corresponding to each rotating body B3. Each driving device B1 is controlled by a control device B6.

  This control device B6 can determine the number of movable rods C to be fed out from the storage location and the respective inclination angles according to the solar altitude measured by this sensor in conjunction with a solar altitude sensor (not shown). This solar altitude sensor may be provided inside or outside the wall body 1. Further, instead of measuring the solar altitude with the solar altitude sensor, the solar altitude may be calculated. For example, solar altitude data for year-round date / time is stored in a computer storage device for each latitude / longitude, and the latitude / longitude of the installation location is entered. The altitude should be calculated.

  The base ends of the first connecting string B4 and the second connecting string B5 that extend inward through the insertion hole formed in the ceiling 2 are fixed to the pair of rotating bodies B3. Each connecting string can be extended to the indoor side and retracted to the ceiling side.

  The leading end of the first connecting string B4 is connected to an appropriate position on the outer portion of each movable rod C, and the distal end of the second connecting string B5 is connected to an appropriate position on the inner portion of each movable rod C.

  A light shielding means E that can be expanded and contracted in the vertical direction is suspended from an appropriate position of the lowest movable rod C to the vicinity of the floor 3. Further, in the illustrated example, the operation unit F is attached near the lowest movable rod C. The operation unit F is connected to the control device B6 by wire (not shown) or wirelessly, and can transmit an operator's command to the control device. The operation unit F may receive a signal transmitted from a remote controller (not shown) and transmit the signal to the control device B6.

  FIG. 2 shows the basic operation of the system. When the operator commands the lifting / lowering mode for a certain movable rod C, the control device B6 drives the driving device B1 corresponding to the certain movable rod. As a result, the first connecting string B4 and the second connecting string B5 are drawn out indoors at a constant speed or pulled into the ceiling, so that each movable rod C can be lifted and lowered while maintaining a certain posture. (See the two-dot chain line in FIG. 2). In the illustrated example, a part of the plurality of movable rods C originally stored in the storage location D is left in the storage location D, and the remaining movable rods C are lowered.

  Next, when the operator commands the tilting mode of the movable rod C, the control device B6 drives the drive device B1, and only one of the first connection string B4 and the second connection string B5 is driven by this drive. It is extended inward or engulfed into the ceiling. Since a plurality of movable rods C are used to block direct light and light is taken into the back of the room, it is necessary to lengthen the protruding size of one movable rod C (the length that the rod protrudes from the wall side). Absent. Therefore, the indoor space can be used widely, and the power required to move each movable rod is not so great. The detailed operation of the system will be described later, and the structure of each member will be described first.

  3 and 4 show the entire configuration of the movable bag storage place D and the lifting mechanism B. FIG.

  A wide-open box D1 is attached to the opening provided in the ceiling 2 shown in FIG. An insertion hole D2 for inserting the first connection string B4 and the second connection string B5 is formed at an appropriate position on the upper plate of the box D1.

  Further, an elevating mechanism B is installed above the box D1. The illustrated lifting mechanism B has a casing B7, and a pair of lifting devices B8 are built in the casing B7. Each of the lifting units B8 is for winding the first connecting string B4, and the other lifting unit B8 is for winding the second connecting string B5.

  Each lifting device B8 includes a lifting unit B9 formed by linearly connecting a driving device B1, a power shaft B2, and a rod-shaped rotating body B3, and a plurality of lifting units B9 are supported by an L-shaped blanket B10. . The rotating body B3 in the illustrated example is constituted by a pipe, and the base ends of the first connecting string B4 to the second connecting string B5 are respectively connected to the three connecting strings. It is fixed so that it can be wound. Depending on the load and length of the panel (inner collar), the number and position of the fixed portions of the string can be appropriately changed.

  Here, the first connecting string B4 and the second connecting string B5 may be anything as long as they have a string shape having a strength to support a load when the movable rod is raised and lowered and tilted, for example, a wire. Can do.

  The rotating body B3 may have any structure as long as the rotating body B3 can be rotated around the rotation axis in the forward direction (the connecting string feeding direction) and in the reverse direction (winding direction). The rotation axis of the rotating body B3 is set parallel to the width direction of the wall body 1. Further, the distance between the virtual extension surface s above the inner surface of the wall 1 shown in FIG. 4 and each rotation shaft is such that a roller C4 (described later) contacts the inner surface of the wall 1 when each movable rod C is lowered into the room. Is determined to be possible.

  FIG. 5 shows the configuration of the movable rod C. The movable rod C is composed of a movable plate C1 and sliding means C2. The movable plate C1 is a plate material that is long in the horizontal direction along the wall 1, and is preferably formed of a material having an appropriate light reflectance. The upper surface of the movable plate C1 may be a mirror surface or a diffuse reflection surface. In addition to the mirror surface material, a member that slightly transmits light (half mirror or milky white panel) may be used.

  The leading ends of the first connecting string B4 are pivotally attached to several places outside the movable plate C1, and the leading ends of the second connecting string B5 are pivotally attached to several places inside the movable plate C1. The pivot location is set so as to be shifted in the longitudinal direction or the width direction of the movable plate C1 between the movable rods C so that the movable rods can be moved up and down independently.

  The sliding means C2 includes a holder C3 attached to the back surface of the movable plate C1, and a roller C4 held on the front end side of the holder C3. In the illustrated holder C3, the rear end portion of the holding rod is inserted into the case with the outer end open via an elastic body, and a roller C4 is attached to the tip of the holding rod. The mounting location of the sliding means C2 may be shifted in the longitudinal direction for each movable rod C. Thereby, even when a plurality of movable baskets C are stacked in the storage place D, it is possible to prevent the sliding means C2 from interfering.

FIG. 6 shows an example of the control method in the summer period to the intermediate period when the movable rod system of the present invention is provided on the south surface.
First, as shown in FIG. 6A, when the solar altitude is high (for example, when the profile angle α is 80 ° or more), shielding and lighting are performed with a single movable rod, but the solar altitude is gradually decreased (for example, α is As it becomes about 70 °, it becomes impossible to shield and light with only one sheet. At this time, as shown in FIG. 6B, the second movable rod comes down from the ceiling surface, and the two movable rods are shielded from light and lighted to prevent direct light from reaching the floor surface. Further, as the solar altitude becomes lower (for example, α becomes about 60 °), the two movable rods are lowered as shown in FIG. Further, when α becomes about 50 °, for example, as shown in FIG. As described above, the distance between the movable rods gradually decreases as the solar altitude decreases. The angle of the movable rod also changes gradually. Thereafter, light shielding and daylighting are performed in the same way up to the final number (see FIGS. 6C to 6D).

  The angle of the movable rod is basically adjusted in accordance with the solar altitude so that the reflected light from the movable rod C hits a specified distance (assuming about 15 m) on the ceiling surface. However, if the solar altitude is too high, the angle of tilting becomes too tight, so an angle limit is provided. In the example of FIG. 6, the angle limitation is not applied in FIG. 6D for the intermediate period, and the angle limitation is applied in FIGS. 6A to 6C for the summer period. . By providing the angle restriction, the reach of light on the ceiling surface is reduced, but the mirror surface portion (upper surface portion) of the movable rod C becomes difficult to see, so the visual feeling is considered to be improved. A method for setting the angle according to the designated distance will be described later.

  FIG. 7 shows an example of a control method in the intermediate period to winter period when the movable rod system of the present invention is provided on the south surface. When the profile angle is 40 °, five movable rods (see FIG. 7A), and when the profile angle is 30 ° to 10 °, six movable rods (FIGS. 7B to 7D). Reference) Shielding and daylighting are performed. If the profile angle is 30 ° or less, the angle limit is set so that the light is as deep as possible in the range where the direct light does not reach the floor with 6 ridges. This is because it is difficult to design an excessive number of movable rods.

  These controls can be realized by operating the control device B6 based on the measured value of the solar altitude sensor as described above. Specific examples of the solar altitude and the number and angle of the ridges mentioned in the above embodiment are used in the control method of the program executed by the control device B6. Further, mathematical formulas used for the control method will be described next.

FIG. 8 shows a method of controlling the tilt angle of the movable rod C of the present application. In the drawing, the relationship between the inclination angle θ of the movable rod C with respect to the horizontal direction and the feeding length ΔL of the second connecting string B5 with respect to the first connecting string B4 is shown. When the distance between the respective ends of the first connecting string B4 and the second connecting string B5 is L, the above ΔL is approximately given by the following equation.
[Formula 1] ΔL = sin θ

  FIG. 9 is a diagram for explaining a control method of the distance d of the light that reflects the movable fence from the window and reaches the ceiling side, the fence distance hs, and the fence angle θ.

First, the reach distance d of the reflected light will be described. 9A, the highest incident point of sunlight on the outer end of the movable rod C and above the movable rod is o, the reflection point on the inner edge side of the movable rod is a, and the ceiling directly above the reflection point a. Is represented as b, the arrival point of the reflected light as c, and the solar altitude as α. If the distance from the point o to the point b is d ₁ and the distance from the point b to the point c is d ₂ , d = d ₁ + d ₂ . D ₁ = L × cos θ. If the distance in the vertical direction between the outer end of the movable rod and the position of the ceiling (the position of another movable rod (not shown) housed on the ceiling side) is h _s , d ₂ = (h _s + h ₁ ) / tan (α-2θ). Furthermore, since it can be seen from the drawing that h ₁ = L × sin θ, the following expression is obtained.
[Formula 2] d ₂ = (h _s + L × sin θ) / tan (α−2θ)

Next, the wrinkle interval h _s will be described. The perpendicular foot drawn from the apex e of the triangular oea to bottom oa shown in FIG. 9 (B) and a point f, the length of the perpendicular line and L _1. Since the relationship of L ₁ = h _s × cos α is derived from the triangle oef and the relationship of L ₁ = L × sin (α−θ) is derived from the triangle aef, the following equation is finally obtained.
[Formula 3] h _s = L × sin (α−θ) / cos α

Next, the saddle angle θ will be described. As described above, h _s × cos α = L × sin (α−θ). This equation can be solved with θ using an inverse trigonometric function.
[Formula 4] θ = α−sin ⁻¹ {(h _s × cos α) / L}

FIG. 10 is a flowchart of control of the movable system of the present invention. The control procedure is explained below.
(A) First, the angle θ of the eyelid is calculated from the profile angle, the height of the window, and the length of the eyelid. In the initial state, for example, the number of baskets may be assumed to be an appropriate number (for example, a minimum number). If the single ridge is placed at the lower limit position of the range of the window whose light amount is to be adjusted with the heel (see FIG. 6A), the distance from the outer edge of the heel to the ceiling is the heel distance h _s. It becomes. Thus, the heel angle θ can be calculated using Equation 4.
(B) Next, it is determined whether or not the calculated saddle angle θ is within a preset lower limit value. When the wrinkle angle is within the lower limit, the wrinkle interval and the number of sheets for preventing direct light are calculated from the profile angle, the wrinkle length, and the wrinkle angle. When the wrinkle angle is not within the lower limit value, the wrinkle angle is reset to the lower limit value, and the wrinkle interval and the number of sheets for preventing direct light are calculated from the profile angle, the wrinkle length, and the wrinkle angle.
(C) Next, it is determined whether the number of cards is within the upper limit range. When the number of saddles is within the upper limit range, the reach distance is calculated from the profile angle, window height, and saddle angle. When the number of saddles is not within the upper limit range, the number of saddles is set to the upper limit value, and the reach distance is calculated from the profile angle, the window height, and the saddle angle.

  In addition, when the control device B6 is configured by a microcomputer and the above mathematical formula is stored, when the desired angle is specified, the first connecting string and the second connecting string are set so that the inclination angle of the movable rod C becomes the angle. The feeding length can be automatically adjusted.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various changes or modifications can be made within the scope of the claims, and such changes or modifications. Are also included within the scope of the present invention.

  Hereinafter, other embodiments of the present invention will be described. In these descriptions, descriptions of the same configurations as those of the first embodiment are omitted.

  11 and 12 show a second embodiment of the present invention. In the present embodiment, gears and clutch means are introduced into the power system between the driving device B1 and the rotating body B3 so that the rotational force is transmitted from one driving device B1 to the rotating shafts of the plurality of rotating bodies B3. It is composed.

  In the illustrated example, as shown in FIG. 11, a driving gear B11 is attached to the power shaft B2 of the driving device B1, and a driven gear B12 is attached to the rotating shafts of the plurality of rotating bodies B3. To the first driven gear B12 and from the first driven gear B12 to the second driven gear B12 via the transmission gear B13. Clutch means B14 is provided between each driven gear B12 and the rotating body B3 so that the respective rotation shafts of the driven gear B12 and the rotating body B3 can be connected or disconnected.

  FIG. 12 is a sectional view of a conventionally known configuration example of the clutch means B14. The clutch means B14 rotates around the rotating shaft in conjunction with the driven gear B12, and engages with the rotating groove B15 having a recessed groove extending in the axial direction on the inner side of the tubular wall, and the recessed groove in the rotating cylinder. Thus, there are a moving piece B16 that rotates together with the rotating cylinder and can move forward and backward in the cylinder axis direction, and a rotating piece B17 that can be rotated by friction with the moving piece B16, and rotates via this rotating piece B17. The rotational force is transmitted to the rotating shaft (power shaft B2) of the moving body B3.

  The two rotating bodies B3 may be a pair of rotating bodies corresponding to one movable rod C. Accordingly, the movable rod C can be tilted by blocking the rotational force applied to one of the two rotating bodies B3 moved by one drive device B1 by the clutch means and rotating only the other.

  13 to 15 show a third embodiment of the present invention. In the present embodiment, a main drive device B20 for raising and lowering the plurality of movable rods C is provided.

  FIG. 13 shows the principle of this embodiment. As shown in the figure, the main drive device B20 is linked to a plurality of rotating bodies B3 via a power shaft B2, a clutch means 14, a driving gear B11, and a driven gear B12. The illustrated driven gear B12 functions for low-speed rotation, medium-speed rotation, and high-speed rotation, respectively, by changing the gear ratio. However, for the sake of simplicity, the diameter of each driven gear is depicted on the drawing.

  In this embodiment, the ratio of the number of rotations of the driven gear for low-speed rotation, the driven gear for middle-side rotation, and the driven gear for high-speed rotation is 3: 2: 1, but the ratio can be changed as appropriate. it can.

  When the solar altitude is high, as shown in FIG. 13A, the clutch means B14 corresponding to the first movable rod from the bottom is connected, and the clutch means B14 corresponding to other movable rods is disconnected. As a result, only the rotating body B3 associated with the first movable rod rotates, and the first movable rod is raised and lowered. When the solar altitude is medium, as shown in FIG. 13B, the clutch means B14 corresponding to the first and second movable rods from the bottom is connected, and the clutch means B14 corresponding to the remaining movable rods is disconnected. Yes. As a result, the ratio of the descending speed of the first movable rod from the bottom to the descending speed of the second movable rod is 2: 1. When the solar altitude is low, the clutch means B14 corresponding to all the movable rods is connected as shown in FIG. As a result, the ratio of the descending speed of the first movable rod from the bottom, the descending speed of the second movable rod, and the descending speed of the third movable rod is 3: 2: 1. Since a constant speed ratio is maintained, the gap between the movable rods and the gap between the movable rod and the storage location of the movable rod are uniform, and the appearance is good.

  With the above configuration, the plurality of movable rods C can be lifted and lowered simultaneously. In FIG. 13, the connecting strings of the movable rods are drawn so as to move between the three rotating bodies arranged in the left-right direction in the figure. (3) a multiple gear that overlaps the driven gear is provided, a chain gear is provided between the multiple gear and the gear attached to the rotating shaft of the rotating body, and the chain is a gear in each stage of the multiple gear by a conventionally known method. What is necessary is just to employ | adopt the gear change mechanism which moves between. 14 and 15 show the configuration of such a known gear change mechanism. In the figure, B23 is a chain gear, and B22 is a driven gear B12 with a transmission means B22. The gist of the structure is that two intermediate gears are attached to the tip of the arm of the transmission means B22, and the chain gear B23 is laid in the order of driving gear → first intermediate gear → second intermediate gear → driven gear. Give it. The arm is moved in the axial direction of the driven gear B12 by a pressing means (not shown) to change the gear from one gear of the driven gear B12 to another gear (see Patent Document 3). .

  In the present invention, the gear change of the movable rod C relative to the rotating body B3 and the on / off of the clutch means may be controlled by the control device B6. Specifically, only the clutch means corresponding to the movable rod C to be removed from the storage location is turned on, the others are turned off, and among the movable rods C to be separated from the storage location, the order counted from the lower side is small. The control device B6 is configured so that the gear ratio is set so that the connection string feeding speed increases as the length increases.

  FIG. 16 shows a fourth embodiment of the present invention. In addition to the configuration of the third embodiment, this embodiment includes an auxiliary drive device B21 for tilting the plurality of movable rods C. The auxiliary driving device B21 is linked to a plurality of rotating bodies B3 via a power shaft B2, a clutch means B14, a driving gear B11, a transmission gear B13, and a driven gear B12.

  In order to tilt the plurality of movable rods C, first, each clutch means on the main drive device B20 side is turned off with respect to each rotating body B3 of the movable rod C detached from the storage location D, and the auxiliary drive device B21 side. Each clutch means is turned on. And what is necessary is just to operate the auxiliary drive device 21 and to transmit a rotational force with respect to the rotary body B3. Thereby, the plurality of movable rods C can be tilted all at once.

17 to 18 show a fifth embodiment of the present invention. In the present embodiment, the plurality of movable rods C are controlled by being divided into a plurality of groups g ₁ , g ₂ ... Composed of the same number of movable rods.

For the movable eaves C _A least significant of each group, with respect to the bottom of movable eaves C _A of the plurality (two in FIG intellectual example), we are prepared two multistage rotary body B25. This multi-stage rotating body B25 is configured by joining a plurality of rotating bodies having different diameters corresponding to the number of groups in a coaxial manner, and rotatably connecting around one rotating shaft. .

  In these configurations, the plurality of first connection strings B4 hanging from the respective stages of the one multistage rotating body B18 are disposed on the outer portion of the movable rod C and from the respective stages of the other one multistage rotating body B25. A plurality of second connecting strings B5 that are suspended are connected to the inner portions of the movable rods C, respectively. The connecting string connected to these movable rods is assumed to be non-stretchable.

In the drawing, the lowermost movable rod C _A is white, and the other movable rods C are white. Further, the non-stretchable portion of the connecting string is painted white, and the elastically extendable portion as described below is painted black with both ends sandwiched by white circles.

  Regarding the movable rods C other than the lowest in each group, the same order counted from the bottom of each group as a pair, the outer portion of the movable rod of the same set is the same one first connecting string B4, The inner portions of the same set of movable rods C are connected in series with the same second connecting string B5. Each connecting string is wound around a separate rotating body B3.

A connecting portion between the movable rods C connected in series is a string portion B26 that can be elastically extended by its own weight. This string portion B26 extends due to the weight of the movable rod C when the movable rod C is separated from the lowermost movable rod, and is appropriate between the other movable rod C in the unfolded state shown in FIG. The elasticity is such that a large distance is maintained. In other words, when the distance is d ₁ and the weight of the movable rod is w, the spring constant k is such that k = d ₁ / w is established.

  The extendable string portion B26 can be bent in advance like an S-shape or a waveform, and the bent portion can be forcibly stretched. In the drawing, the extendable string portion is painted black, but it is not necessary that the entire black painted portion can be extended.

  FIG. 18 shows a preferred example of this embodiment. In this example, a mainspring type winding means B27 is provided in a part of the extendable string portion B26 (in the illustrated example, the attachment portion to the movable rod). This winding means B27 rotatably supports a winding shaft B29 inside a case B28 having a string outlet B30, and winds a string of a certain length around the winding shaft B29. The legs of the mainspring B31 connected to the winding shaft B29 are locked inside the case B28. The case B28 is fixed to the movable plate C1 of the movable rod. The elastic force of the spring B31 is designed to be smaller than the load of one movable rod. Thereby, when a load of a movable rod is applied to the connecting string, the connecting string is pulled out against the elastic force of the mainspring B31, and when the load is released, the connecting string is wound up again.

In the present embodiment, as the basis for operating a lowermost movable eaves C _A, the ratio of the diameter of each stage of the multistage rotary body, in the case of 2 split 1: 2, in the case of 3 split 1: 2 : It is good to set so that it becomes an integer multiple like 3. Then, when the multi-stage rotating body B25 is rotated by a certain amount, the reference movable rod C moves all at once at a speed proportional to the diameter ratio from the storage place D and stops at a fixed position. Thus lowest distance between the movable visor C _A constant. The movable rods other than the lowest in one group are pushed down by the lowest movable rod in the upper group (see FIG. 17 (A)) and then descend by their own weight (see FIG. 17 (B)). .

  According to the configuration of the present embodiment, the number of driving devices and connecting strings can be omitted. As a preferred embodiment, if the number of movable rods is about 6, two driving devices are applied to each movable rod as in the first embodiment, and if it is more than that, the movable rod is appropriately used. It can be divided into groups and can be individually controlled for each group as in this embodiment.
