The traveling roller 68 is accommodated so as to be able to travel a runner passage in the indoor side rail 1F. An auxiliary roller 70 is rotatably supported by the pair of runner members 64 a and 64 b obliquely below the traveling roller 68. The auxiliary roller 70 is disposed at a position sandwiched by the opening edge of the bottom side opening of the indoor side rail 1F, and rolls on the opening edge when the leading runner 5F moves. Retaining holes that fit with the mounting shafts 51a and 52a of the belt joints 51 and 52 at positions not overlapping the traveling roller 68 and the auxiliary roller 70 when viewed from the thickness direction of the pair of runner members 64a and 64b, respectively. 84 are formed. The belt joints 51 and 52 are connected to the leading runner 5F by fitting the mounting shafts 51a and 52a into the holding holes 84, respectively.

  The belt joints 51 and 52 are formed of a synthetic resin, and each include a belt holding portion 53 for holding the end 9 a of the transfer belt 9. Each of the belt holders 53 is integrally formed with the attachment shafts 51a and 52a, and is configured to be snap-engageable with the holding members 51b and 52b. That is, the claws 57 of the holding members 51b and 52b are engaged snap-fit through the space surrounded by the concave portion 56 provided in the belt holding portion 53. Further, the width of the end 9a of the transfer belt 9 is narrower than the width of the other portion 9c, and has an engagement tooth 9b of a predetermined pitch. The belt holding portion 53 is formed with a plurality of engagement recesses 55 with which the engagement teeth 9 b are engaged. Therefore, the belt joints 51 and 52 hold the end 9a of the transfer belt 9 by holding the end 9a of the transfer belt 9 in the thickness direction by the respective belt holding portions 53 and the holding members 51b and 52b. It can be done.

  Thus, the leading runner 5F movable in the indoor rail 1F is fixed to the transfer belt 9 in the indoor rail 1F.

  As shown in FIG. 4, in the leading runner 5R, mainly, a pair of runner members 64a and 64b made of synthetic resin and a metal connection plate 63 to which the pair of runner members 64a and 64b are attached are integrated by screws 83. It is a member connected in a way. A fitting hole 79 is formed in the main body 67 of the pair of runner members 64a and 64b so that the fitting piece 78 of the connecting plate 63 can be fitted from below. Then, the fitting piece 78 of the connecting plate 63 is fitted from below the main body 67 of the pair of runner members 64a and 64b, and the insertion hole 80 provided in the lower portion of each main body 67 of the pair of runner members 64a and 64b The screw hole 82 provided in the connecting plate 63 is aligned, and the screw 83 is screwed into the screw hole 82 of the connecting plate 63 located in the main body 67 through the insertion hole 80 to penetrate the main body 67. It is connected integrally.

  A pair of traveling rollers 68 is rotatably supported by the pair of runner members 64a and 64b so as to be sandwiched in the thickness direction. The traveling roller 68 is movably accommodated in a runner passage in the outdoor side rail 1R. An auxiliary roller 70 is rotatably supported by the pair of runner members 64 a and 64 b obliquely below the traveling roller 68. The auxiliary roller 70 is disposed at a position sandwiched by the opening edge of the bottom side opening of the indoor side rail 1F, and rolls on the opening edge when the leading runner 5R moves. Each runner member 64a, 64b is configured by inserting the pin 72 through the support hole 74 provided in the upper portion 73 of the main body 67 into the auxiliary roller 70 and then attaching the traveling roller 68 to the main body 67 with the core shaft 77. be able to.

  The pair of runner members 64a and 64b are engaged with the main body 90a of the contact piece 90 projecting in a substantially square rod shape at a position not overlapping the traveling roller 68 and the auxiliary roller 70 when viewed in the thickness direction A holding hole 84 is formed. By attaching the main body 90a of the abutted piece 90 to the holding hole 84, the abutted piece 90 is connected to the leading runner 5R, and the tip of the main body 90a from the side portion of the leading runner 5R has a thickness of the traveling roller 68 Protrusively longer than.

  The abutted piece 90 is formed of a synthetic resin, and includes a main body 90a and a proximal end 90b. The proximal end 90 b functions as a fall prevention of the main body 90 a with respect to the holding hole 84.

  In addition, the contact piece 90 can be made into various forms by the attachment method. As a method of attaching the abutted piece 90 to the holding hole 84, for example, fitting, press-fitting, adhesion or the like is assumed. For example, as shown in FIG. 5A, when attaching by fitting, a hook-like fitting projection 90c is provided on the side of the main body 90a of the abutted piece 90, and the tip of the main body 90a is After being inserted into the holding hole 84, it can be configured to be locked by the fitting projection 90c. Alternatively, as shown in FIG. 5 (b), when attaching by press-fitting, the main body 90a is configured to expand in cross section from the tip to the base end, and the tip of the main body 90a is inserted into the holding hole 84. Then, it can be configured to be pressed and locked. Further, as shown in FIG. 5C, when attaching by adhesion, for example, the tip of the main body 90a can be inserted into the holding hole 84 and then fixed by the adhesive 95.

  In this manner, the leading runner 5R movable in the outdoor rail 1R can be configured in common with most members constituting the leading runner 5F except for the abutted piece 90, and It is suppressing the cost rise. However, when it is not intended to share the leading runner 5F with the leading runner 5F, the runner member 64b and the non-contacting piece 90 may be an integral part.

  On the other hand, the locking block 12 fixed to the transfer belt 9 in the outdoor side rail 1R has a contact piece 25 capable of coming into contact with the abutted piece 90 of the leading runner 5R. The locking block 12 can also be configured in a form in which the main body 90 a of the abutted piece 90 is shortened.

  As shown in FIG. 6, the locking block 12 is made of synthetic resin, and is composed of a belt holding member 12a and a holding member 12b. The belt holding member 12a is adapted to snap-engage the claws 21 of the holding member 12b through the space surrounded by the recess 23 provided in the belt holding member 12a. The transfer belt 9 has a narrow portion 9d narrower than the width of the other portion 9c which is not a place to which the locking block 12 is attached, and has engaging teeth 9b of a predetermined pitch. . The belt holding member 12a is formed with a plurality of engagement recesses 24 with which the engagement teeth 9b are engaged. Therefore, the locking block 12 can hold the narrow portion 9d of the transfer belt 9 by holding the narrow portion 9d of the transfer belt 9 in the thickness direction by the belt holding portion 12a and the holding member 12b. . The belt holding member 12a is formed with a contact piece 25 which can come in contact with the contact piece 90 of the leading runner 5R.

  In this manner, the locking block 12 fixed to the transfer belt 9 in the outdoor rail 1R is configured to have the contact piece 25 capable of coming into contact with the contact piece 90 of the leading runner 5R. .

  Next, with reference to FIG. 7, the relative positional relationship between the leading runner 5R and the locking block 12 in the outdoor side rail 1R and the relative positional relationship between the runner 4 and the locking block 12 in the outdoor side rail 1R will be described. . FIGS. 7A and 7B are plan views showing the relative positional relationship between the leading runner 5R and the locking block 12 and the relative positional relationship between the runner 4 and the locking block 12, respectively.

As shown in FIG. 7A, the relative positional relationship between the leading runner 5R and the locking block 12 is such that the abutted piece 90 of the leading runner 5R and the abutting piece 25 of the locking block 12 can contact each other. It is guided by the outdoor side rail 1R. On the other hand, as shown in FIG. 7B, in the runner 4, the pair of traveling rollers 41 is rotatably supported by the core shaft 42 so as to be sandwiched in the thickness direction of the main body 40. Further, although the main body 40 rotatably supports the suspending member 43 for suspending the curtain material on the horizontal surface, the pair of traveling rollers 41 can travel along the runner passage of the outdoor side rail 1R. Since it is accommodated, the relative positional relationship between the runner 4 and the locking block 12 is always guided by the outdoor side rail 1R so as not to abut each other.

  In the double curtain device of the first embodiment configured as described above, the curtain material is obtained by the contact / non-contact between the contact piece 25 of the locking block 12 and the contact piece 90 of the leading runner 5R. When closing the curtain member 7F with the 7R and the curtain member 7F fully open, the curtain member 7R is also closed simultaneously, and when the curtain member 7R is fully closed, the curtain member 7R is opened and closed. Is maintained in the fully closed state, and when the curtain 7R is opened and closed with the curtain 7F in the fully open state, the curtain 7F is maintained in the fully open state.

  This operation will be described with reference to FIGS. 8 to 10. In each of FIGS. 8 to 10, (a) and (c) are plan views, (b) and (d) are schematic front views, and (a) and (b) correspond to each other. Explanatory drawing and (c) and (d) are the state explanatory views corresponding to each other.

  First, referring to FIGS. 8 (a) and 8 (b), FIGS. 8 (a) and 8 (b) are plan views showing the operation when the curtains 7F and 7R are both fully open and the curtains 7F are closed. It is a front view showing a figure and outline. When both the curtains 7F and 7R are fully open and the curtain 7F is operated to close in the left direction, the leading runner 5F that suspends and supports the curtain 7F moves in the leftward direction in the indoor rail 1F. Then, since the leading runner 5F is fixed to the transfer belt 9, the transfer belt 9 moves clockwise in the figure. At this time, the locking block 12 is fixed to the transfer belt 9 moving rightward in the outdoor side rail 1R, and the contact piece 25 of the lock block 12 and the abutted piece 90 of the leading runner 5R It abuts and moves the leading runner 5R rightward in the outdoor side rail 1R. Therefore, the curtain material 7R suspended and supported by the leading runner 5R moves in the right direction in synchronization with the movement of the curtain material 7F in the left direction. Therefore, when closing the curtain material 7F from a state in which the curtain material 7R and the curtain material 7F are fully open, the curtain material 7R is also closed at the same time, and as a result, as shown in FIG. In the above operation, both curtains 7F and 7R can be fully closed.

  Next, referring to FIGS. 9 (a) and 9 (b), FIGS. 9 (a) and 9 (b) show the operation when the curtain 7F is closed from the fully open state with the curtain 7R being fully closed. They are the top view which shows these, and a front view shown roughly. When the curtain member 7F is operated to close the curtain member 7F from the fully open state with the curtain member 7R being fully closed, the leading runner 5F that suspends and supports the curtain member 7F moves in the indoor side rail 1F in the left direction. Then, since the leading runner 5F is fixed to the transfer belt 9, the transfer belt 9 moves clockwise in the figure. At this time, the locking block 12 is fixed to the transfer belt 9 moving rightward in the outdoor side rail 1R, and the locking block 12 also moves rightward, but the curtain material 7R is fully closed. Therefore, the leading runner 5R is located at the right end of the outdoor side rail 1R. Therefore, the abutment piece 25 of the locking block 12 does not abut on the abutted piece 90 of the leading runner 5R until it is positioned at the right end of the outdoor rail 1R, and the position of the leading runner 5R does not change. Therefore, the movement of the curtain material 7R suspended and supported by the leading runner 5R also does not change. Similarly, referring to FIGS. 9 (c) and 9 (d), FIGS. 9 (c) and 9 (d) respectively show opening of the curtain 7F from the fully closed state with the curtain 7R being fully closed. They are the top view which shows operation | movement, and a front view shown roughly. Also in this case, the front runner 5R is located at the right end of the outdoor side rail 1R because the curtain 7R is fully closed. Therefore, even if the transfer belt 9 moves, the contact piece 25 of the locking block 12 does not contact the contact piece 90 of the leading runner 5R until it is positioned at the right end of the outdoor rail 1R. The position of the leading runner 5R does not change. Therefore, the movement of the curtain material 7R suspended and supported by the leading runner 5R also does not change. Therefore, when opening and closing the curtain material 7F from the state of the curtain material 7R being fully closed, the motion of the curtain material 7R can be maintained without changing the movement of the curtain material 7R.

Explanatory drawing and (c) and (d) are the state explanatory views corresponding to each other.

  First, referring to FIGS. 13 (a) and 13 (b), FIGS. 13 (a) and 13 (b) are plan views showing the operation when the curtains 7F and 7R are both fully open and the curtains 7F are closed. It is a front view showing a figure and outline. When both the curtain members 7F and 7R are fully open, the curtain member 7F is operated to close in the right direction, the leading runner 5F that suspends and supports the curtain member 7F moves in the indoor rail 1F in the right direction. Then, since the leading runner 5F is fixed to the transfer belt 9, the transfer belt 9 in the indoor side rail 1F moves clockwise in the figure, and the first drive gear 16 also rotates clockwise in the figure. At this time, the rotation of the first drive gear 16 is transmitted to the second drive gear 18, and the transfer belt 9 in the outdoor outer rail 1R also rotates clockwise in the drawing. A locking block 12 is fixed to the transfer belt 9 in the outdoor side rail 1R, and the contact piece 25 of the lock block 12 abuts on the abutted piece 90 of the leading runner 5R to make the leading runner 5R a chamber.

Therefore, the movement of the curtain material 7R suspended and supported by the leading runner 5R also does not change. Similarly, referring to FIGS. 14 (c) and 14 (d), FIGS. 14 (c) and 14 (d) show the operation when the curtain 7F is closed from the fully open state while the curtain 7R is fully closed. They are the top view which shows these, and a front view shown roughly. Also in this case, the front runner 5R is located at the right end of the outdoor side rail 1R because the curtain 7R is fully closed. Therefore, the abutment piece 25 of the locking block 12 does not abut on the abutted piece 90 of the leading runner 5R until it is positioned at the right end of the outdoor rail 1R, and the position of the leading runner 5R does not change. Therefore, the movement of the curtain material 7R suspended and supported by the leading runner 5R also does not change. Therefore, when opening and closing the curtain material 7F from the state of the curtain material 7R being fully closed, the motion of the curtain material 7R can be maintained without changing the movement of the curtain material 7R.

  Next, referring to FIGS. 15 (a) and 15 (b), FIGS. 15 (a) and 15 (b) respectively fold the curtain 7R from the fully closed state to the right with the curtain 7F being fully open. They are the top view which shows the operation | movement at the time of opening at 1, and a front view shown roughly. When the curtain member 7R is operated to open the curtain member 7R from the fully closed state with the curtain member 7F in the fully open state, the leading runner 5R not fixed to the transfer belt 9 contacts the locking block 12 to move in the right direction in the drawing. There is no such thing. Therefore, the transfer belts 9 for the rails 1R and 1F do not move, and the leading runner 5F does not move, so the curtain material 7F is also maintained in the fully open state. Similarly, referring to FIGS. 15 (c) and 15 (d), in FIGS. 15 (c) and 15 (d), with the curtain 7F fully open, the curtain 7R is folded leftward from the fully closed state. They are the top view which shows the operation | movement at the time of opening at 1, and a front view shown roughly. Also in this case, since the leading runner 5F does not move, the curtain material 7F is also maintained in the fully open state. Therefore, when opening and closing the curtain material 7R from the fully open state of the curtain material 7F, the movement of the curtain material 7F is not changed, and the fully open state can be maintained.

  As described above, according to the second embodiment, when the curtain material 7R (for example, the lace curtain) and the curtain material 7F (for example, the drape curtain) are fully open, the lace curtain is closed simultaneously. When the draped curtain is opened and closed while the lace curtain is fully closed, the laced curtain is kept fully closed. When the lace curtain is opened and closed while the draped curtain is fully open, the draped curtain is fully opened. Maintained. In addition, when configuring the double curtain device electrically, cost reduction can be achieved with one motor, and control burden on each motor can be reduced. Therefore, the cost does not occur in the quality. Can be adapted to the actual usage form while improving the
