  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Various characteristic items shown in the following embodiments can be combined with each other. In the embodiment described below, an example of application to a string pull curtain rail is shown, but in the present invention, the shielding material is opened and closed with a change in angle in accordance with the movement of a runner supported so as to be movable along the hanger rail. It can also be applied to other shielding devices.

1. First Embodiment A first embodiment of the present invention will be described with reference to FIGS. The shielding device of the present embodiment includes a large number of runners 3 a and 3 b supported so as to be movable along the hanger rail 1. The hooks of the runners 3 a and 3 b protrude downward through an opening groove 1 a provided in the hanger rail 1, and a curtain (shielding material) 11 is suspended and supported by the runners 3 a and 3 b via a hook member 13.

  A guide portion 7 is provided at one end of the hanger rail 1 (the right end in FIG. 1A). The guide unit 7 includes a support shaft 7a fixed to the hanger rail 1 and a pulley 7b rotatably supported by the support shaft 7a. The operation cord 5 is hung on the pulley 7b, extends along the hanger rail 2, and is bent by the pulley 15 provided at the other end of the hanger rail 2 (the left end in FIG. 1A). As shown in c), the hanger rail 2 is hung in a loop from the other end.

  The operation code 5 is connected to two adjacent top runners 3a at positions P1 and P2. The leading runner 3 a can be moved in the hanger rail 1 by operating the operation cord 5 that is suspended from the hanger rail 1. For example, when the opening direction operation portion 5o of the operation cord 5 is pulled down as shown by the arrow A in FIG. 1C, the two leading runners 3a are separated from each other as shown by the arrow A in FIG. Move in the direction. The runners other than the head runner 3a are subsequent runners 3b. When the head runner 3a moves in the direction of arrow A, the runner is pulled by the curtain 11 to move together with the head runner 3a, and the curtain 11 is opened.

On the other hand, when the operation cord 5 is moved in the direction opposite to the arrow A by lowering the closing direction operation portion 5s of the operation cord 5 as indicated by the arrow B in FIG. It moves and the curtain 11 is closed. In addition, since the curtain 11 moves with the movement of the head runner 3a, the subsequent runner 3b connected to the curtain 11 also moves with the curtain 11.
As described above, the curtain 11 is opened and closed by the operation of the operation code 5.

  As shown in FIG. 1C, the operation cord 5 is drooped in a loop shape, and if the user is caught by the lower end R of the loop, there is a possibility of causing an accident. Therefore, in this embodiment, the safety is ensured by providing the separation portion 9 that is separated when an excessive tensile force exceeding a predetermined threshold is applied to the operation cord 5. In the present embodiment, the separation unit 9 is provided so as to connect both ends of the operation cord 5. As a threshold value at which the separation unit 9 is separated, a value larger than the tensile force applied to the operation cord 5 when the curtain 11 is opened and closed is set normally. It is also possible to make the value small enough to be surely separated even when a user with a low weight such as an infant is caught by the operation cord 5. For example, the load applied to the loop is set to 5 to 6 kgf, and the tensile force applied to the operation cord alone is set to a value of 2 to 3 kgf or less. An example of the configuration of the separation unit 9 is shown in FIG.

  2 includes a male member 115 and a female member 116 molded of synthetic resin. The female member 116 is formed in a cylindrical shape, and a locking groove 117 is formed in the circumferential direction on the inner peripheral surface of the tip.

  An insertion hole 118 through which the operation cord 5 can be inserted is formed at the base end portion of the female member 116. In order to attach the operation cord 5 to the female member 116, the end of the operation cord 5 is inserted into the insertion hole 118 from the proximal end side of the female member 116. When the caulking member 119 is attached to the end of the operation cord 5 and caulked, the caulking member 119 comes into contact with the peripheral portion of the insertion hole 118 in the female member 116 as shown in FIG. Is held by the female member 116.

  The male member 115 is attached to the end of the operation cord 5 by outsert molding. The distal end portion of the male member 115 is formed with a diameter that can be fitted to the distal end portion of the female member 116, and a protrusion 120 that can be engaged with the locking groove 117 is formed in the circumferential direction on the outer peripheral surface of the distal end portion. Is formed.

  And if the front-end | tip part of the male type | mold member 115 is fitted to the front-end | tip part of the female-type member 116, the protrusion 120 will be engaged with the latching groove | channel 117 elastically. In this state, when an excessive tensile force exceeding a predetermined threshold is applied to the male member 115 and the female member 116 in the direction in which the male member 115 and the female member 116 are separated from each other, the fitting between the male member 115 and the female member 116 is released. Yes.

  With the above configuration, when an excessive tensile force is applied to the operation cord 5, the operation cord 5 is non-looped to ensure safety. Moreover, it is preferable that the isolation | separation part 9 is comprised so that it can return to an original state by reconnecting after isolation | separation.

  Further, the exposed portion length L1 of the operation cord 5 from the hanger rail 1 is preferably equal to or longer than the moving distance L2 of the leading runner 3a when the curtain 11 is opened and closed. The moving distance L2 is between the position l2 where the leading runners abut each other when fully closed and cannot move in the fully closed direction from the position l1 where the runner is folded when fully opened and the runner or the curtain itself abuts and cannot move further in the fully open direction. Is the distance. In this case, the separation part 9 can be arranged so that the separation part 9 is always outside the hanger rail 1 when the curtain 11 is opened and closed. According to such a configuration, since the separation part 9 does not enter the hanger rail 1, it is easy to grasp the connection state of the separation part 9.

  Moreover, it is preferable to arrange | position the isolation | separation part 9 so that tensile force may not be added to the isolation | separation part 9 when operating the operation cord 5 so that runner 3a, 3b may be moved to the direction which opens the curtain 11. FIG. For example, in the case of FIG. 1C, when opening the curtain 11, the upper portion of the opening direction operation portion 5 o of the operation cord 5 is gripped, and the operation cord 5 is pulled down in the direction of arrow A. Accordingly, by placing the separating portion 9 at a relatively low position in the opening direction operation portion 5o of the operation cord 5 as shown by a position r1 in FIG. 1C, a tensile force is applied to the separating portion 9 when the curtain 11 is opened. Can be prevented.

  When the curtain 11 is opened, the separation unit 9 moves from the position r1 to the position r2 while the leading runner 3a moves from the position l1 to the position l2. Since the position r2 is higher than the position r1, when closing the operation direction 5s of the operation cord 5 as shown by the arrow B in order to close the curtain 11, the lower side than the separation unit 9 is gripped. Easy to pull down. In this case, a tensile force is applied to the separating portion 9.

  In this way, the position r2 of the separation part 9 with the curtain 11 closed is made higher than the position r1 of the separation part 9 with the curtain 11 open, so that the separation is performed only when the curtain 11 is opened. A tensile force can be applied to the portion 9. When the curtain 11 is opened, the operation cord 5 is pulled down against the resistance force caused by the runner or the accumulation of the fabric. Therefore, when the curtain 11 is opened, the tensile force applied to the operation cord 5 closes the curtain 11. At this time, it becomes larger than the tensile force applied to the operation cord 5. Therefore, the maximum tensile force applied to the separating portion 9 can be reduced by setting the positions r1 and r2 of the separating portion 9 in the open state and the closed state of the curtain 11 as described above. Further, in order to further reliably suppress the tensile force from being applied to the separating portion 9 during the opening direction operation of the curtain 11, the length of the closing direction operation portion 5s is set to L2 or more, and the separating portion 9 is provided to the closing direction operation portion 5s. It is preferable to provide it.

  The diameter of the separating portion 9 is determined by the diameter of the introduction port 14 of the operation cord 5 or the clearance between the pulley 15 provided in the introduction port 14 and the guide portion for both the male member 115 and the female member 116. Largely formed. Even when the operation cord 5 is unlooped when an excessive tensile force is applied to the operation cord 5, the male member 115 or the female member 116 of the separating portion 9 is not connected to the inlet 14 of the operation cord 5 or the pulley. It is impossible to pass through the gap between 15 and its guide part, and it is prevented from being drawn into the runner travel space inside the hanger rail 1. Therefore, the user can identify the connection state of the separation part 9, and it becomes easy to reconnect the separated male member 115 and female member 116 at the exposed portion and return to the original state.

This embodiment can also be implemented in the following forms.
-Although the said embodiment is an example of application to the double curtain curtain which uses two runners of substantially the center as a head runner, the same structure is applicable also to a single curtain curtain. In this case, the operation code 5 may be connected to the runner at the end, and this runner may be used as the top runner. In the case of double-opening curtain rails, the runner moving distance L2 when opening and closing is about half the width of the hanger rail 1, but in the case of single-opening curtain rails, the runner moving distance L2 when opening and closing is Is almost equal to the width of. Therefore, in the example applied to the single curtain curtain, the exposed portion length L1 is preferably equal to or longer than the length obtained by subtracting the convolution dimension from the width of the hanger rail 1.
The guide portion 7 is constituted by a sliding surface provided on an end cap attached to the end portion of the hanger rail 1, for example, instead of the shaft 7a and the pulley 7b, and the operation cord 5 is slid on the sliding surface. You may make it make the operation cord 5 circulate within the hanger rail 1 by moving.
-A tension pulley or a tension weight through which the separating portion 9 can pass may be installed at the lower end R of the loop. In this case, the length from the inlet 14 to the tension pulley or tension weight may be set to L2 or more. Further, the separating unit 9 is preferably provided at a position where the tensile force is not applied when the curtain 11 is operated in the opening direction and the tensile force is applied when the curtain 11 is operated, for example, in the closing direction operation portion 5s.

2. Second Embodiment A second embodiment of the present invention will be described with reference to FIGS. This embodiment is similar to the first embodiment, and this embodiment is an example applied to a single curtain curtain, and safety is ensured by providing a separation portion 9 on a split runner 3a. This is the main difference. Hereinafter, the difference will be mainly described.

  This embodiment is an example applied to a single curtain curtain, and the runner at the end is the leading runner 3a, and the remaining runner is the subsequent runner 3b. Then, by operating the operation code 5, the curtain 11 is opened and closed by moving the leading runner 3 a in the hanger rail 1. In FIG. 3, the leftmost runner is the leading runner 3a, but the rightmost runner may be the leading runner 3a.

  The leading runner 3a includes first and second runners 4a and 4b. One end of the operation cord 5 is connected to the runner 4a at the position P1, and the other end of the operation cord 5 is connected to the runner 4b at the position P2. The runner 4a includes arms 4a1 each having a locking claw 4a2 at the tip on both sides in the front-rear direction shown in FIG. The pair of arms 4a1 sandwich the both side surfaces 4b1 of the runner 4b, and the locking claws 4a2 are locked on the back surface of the runner 4b, whereby the runners 4a and 4b are engaged. The runner 4 a includes a hook 4 a 4 that protrudes downward from the opening groove 1 a provided on the support surface 1 b of the hanger rail 1. The hook 4a4 is provided with an opening 4a5 for hooking the hook member 13. The runners 4a and 4b include rollers 4a3 and 4b3 that roll on the support surface 1b.

  In the present embodiment, the runner 4a, 4b is a separation portion 9, and when an excessive tensile force exceeding a predetermined threshold is applied to the operation cord 5, the distance between the pair of arms 4a1 is increased and the runner 4a, The engagement between 4b is released, and the operation cord 5 is non-looped to ensure safety. After the engagement is released, the runners 4a and 4b are separated by sliding in the hanger rail 1 without dropping from the opening groove 1a of the hanger rail 1. When returning to the original state, the runners 4a and 4b can be slid and moved closer together in the hanger rail 1 to be re-engaged, so that the original state can be easily returned. The front-rear width (width in the front-rear direction in FIG. 3B) W of the opening groove 1a at the center of the travel surface in the hanger rail 1 is the left-right width in the travel direction of the runners 4a, 4b (left-right direction in FIG. 3B). Less than width). Therefore, even if the runners 4a and 4b rotate in the horizontal direction in the separated state, the runners 4a and 4b do not fall off the opening groove 1a. The runner front and rear widths may be substantially the same as the front and rear widths of the runners 4 a and 4 b so that the runners 4 a and 4 b cannot be rotated in the hanger rail 1 in the horizontal direction. In that case, the front-rear width W of the opening groove 1a at the center of the running surface may be larger than the left-right width in the running direction of the runners 4a, 4b. The runners 4a and 4b may be configured so that the runners 4a and 4b cannot be rotated in the horizontal direction within the hanger rail 1 by providing the running surface with ridges or ridges that restrict the movement of the rollers 4a3 and 4b3 in the front and rear direction. This also prevents the runners 4a and 4b from rotating in the horizontal direction when the runners 4a and 4b are separated from each other, so that the runners 4a and 4b do not fall off the opening groove 1a. The runners 4a and 4b only need to be able to travel on the bottom surface (support surface) in the hanger rail 1, and even the rolling runners interposing the rollers 4a3 and 4b3 with respect to the support surface 1b slide as shown in FIG. You may be a runner.

This embodiment can also be implemented in the following forms.
-Although the said embodiment is an application example to a single curtain curtain, the same structure is applicable also to a double curtain rail. In this case, as shown in FIG. 1, the two runners in the approximate center are the leading runners, and the operation cords 5 are connected to these runners so that these runners move in opposite directions when the operation cords 5 are operated. do it. Similarly, the third to sixth embodiments can also be applied to the double curtain curtain.

3. Third Embodiment A third embodiment of the present invention will be described with reference to FIGS. This embodiment is similar to the second embodiment, and is mainly different in that safety is ensured by providing a separation portion 9 between the operation cord 5 and the leading runner 3a. Hereinafter, the difference will be mainly described.

  This embodiment is an example applied to a single curtain curtain, and the runner at the end is the leading runner 3a, and the remaining runner is the subsequent runner 3b. Then, by operating the operation code 5, the curtain 11 is opened and closed by moving the leading runner 3 a in the hanger rail 1. The runners 3a and 3b are provided with rollers 3a3 and 3b3, and the rollers 3a3 and 3b3 are arranged between the two guide strips 1c parallel to each other so that the runners 3a and 3b extend along the guide strips 1c. It can be moved. In FIG. 5, the rightmost runner is the leading runner 3a, but the leftmost runner may be the leading runner 3a.

Hereinafter, the runners 3a and 3b of the present embodiment will be described with reference to FIGS. In FIGS. 6A to 6E, the runners 3a and 3b are illustrated with the hooks and rollers omitted for convenience.
As shown in FIGS. 6A to 6B, one end and the other end of the operation cord 5 are connected to the leading runner 3a. An engaging portion 5 a is provided at one end of the operation cord 5. The engaging part 5a includes a substantially cylindrical main body part 5a1 and an expanded diameter part 5a2 projecting annularly from the main body part 5a1 in the radial direction. The leading runner 3a includes an engaging portion 3c that engages with the engaging portion 5a. The engaging portion 3c includes an opening 3c1 having substantially the same shape as the main body 5a, and an annular engaging groove 3c2 provided in the opening 3c1. By inserting the main body 5a1 into the opening 3c1 and engaging the expanded diameter portion 5a2 with the engagement groove 3c2, the engagement portions 5a and 3c can be engaged with each other. A stopper 5 b is provided at the other end of the operation cord 5. When the stopper 5b is locked by the leading runner 3a, the other end of the operation cord 5 is connected to the leading runner 3a at the position P1.

  In the present embodiment, the separation portion 9 is provided between the operation cord 5 and the leading runner 3a. When an excessive tensile force exceeding a predetermined threshold is applied to the operation cord 5, as shown in FIG. The engagement between the engaging portions 5a and 3c is released, and the operation cord 5 is non-looped to ensure safety. After the engagement is released, the original state can be restored by re-engaging the engaging portions 5a and 3c.

  Further, as shown in FIGS. 6D to 6E, the operation cord 5 can be inserted into the subsequent runner (preferably the subsequent runner adjacent to the leading runner 3a) 3b, and the engagement portion 5a cannot be inserted. It is preferable to provide the insertion hole 3b1. In this case, even if the engaging portions 5a and 3c are separated, the engaging portion 5a is locked by the subsequent runner 3b, so that the subsequent runner 3b close to the leading runner 3a moves to the end of the hanger rail 1. However, the further movement of the engaging portion 5a is prevented, and the engaging portion 5a is not pinched by the pulley 15 or dropped from the hanger rail 1. Further, since the insertion hole 3b1 and the engaging portion 3c are located at the same position substantially overlapping in the front-rear surface direction while being positioned on the runner travel line, the succeeding runner that prevents the engaging portion 5a from moving from the separated state By bringing 3b close to the leading runner 3a, the engaging portion 5a can be easily brought into contact with the engaging portion 3c. Re-engagement can be achieved by inserting the rounded engagement portion 5a into the engagement portion 3c. For this reason, it becomes easy to re-engage the engaging portions 5a and 3c. In FIG. 6D, the insertion hole 3b1 is notched, but it may be a closed through hole. The insertion hole through which the operation cord 5 can be inserted and the engaging portion 5a cannot be inserted may be provided in another member that does not support the curtain in the hanger rail 1 instead of being provided in the subsequent runner 3b. Even in this case, since the engaging portion 5a remains in the hanger rail 1, it is easy to return to the original state.

4). Fourth Embodiment A fourth embodiment of the present invention will be described with reference to FIG. This embodiment is similar to the third embodiment, with the main difference being that when an excessive tensile force is applied to the operation cord 5, the diameter of the operation cord 5 is increased instead of being non-looped. is there. Hereinafter, the difference will be mainly described.

  In the present embodiment, the configurations of the other end of the leading runner 3a and the operation cord 5 are the same as those in the third embodiment. The operation cord 5 includes a surplus length portion 5c on the distal end side of the engaging portion 5a similar to that of the third embodiment, and the distal end of the surplus length portion 5c is connected to the front runner 3a at the position P2. The surplus length portion 5c is provided on the traveling surface of the hanger rail 1, or is supported by a guide piece or guide strip provided at another height position or front and rear position in the hanger rail 1, and is pushed by the leading runner or When pulled, it can move back and forth with the leading runner.

  According to such a configuration, when an excessive tensile force exceeding a predetermined threshold is applied to the operation cord 5 and the engagement between the engaging portions 5a and 3c is released, the operation cord 5 is unlooped. Instead, the diameter is increased by the length of the extra length portion 5c. If the diameter of the operation cord 5 is increased, the position of the lower end R of the loop of the portion hanging from the hanger rail 1 is lowered accordingly, and safety is ensured. Further, even after the engagement portions 5a and 3c are disengaged, one end of the operation cord 5 remains connected to the leading runner 3a, so that it is easy to return to the original state.

5. Fifth Embodiment A fifth embodiment of the present invention will be described with reference to FIGS. The present embodiment is the same as the first embodiment in terms of ensuring safety by providing the operation cord 5 with the separation portion 9, but the operation cord 5 is disposed in the hanger rail 1. The main difference is that it is connected to. Hereinafter, the difference will be mainly described. The loop belt 17 corresponds to the “loop body” in the claims, and a string-like loop cord can be used as the loop body in addition to the belt-like loop belt 17.

  The shielding device of the present embodiment includes a large number of runners 3 a and 3 b supported so as to be movable along the hanger rail 1. The runners 3 a and 3 b protrude downward through an opening groove 1 a provided in the hanger rail 1, and a curtain (shielding material) 11 is suspended and supported by the runners 3 a and 3 b through a hook member 13.

  Guide portions 19 and 29 are provided at both ends of the hanger rail 1. Each of the guide portions 19 and 29 includes support shafts 19a and 29a fixed to the hanger rail 1 and pulleys 19b and 29b rotatably supported by the support shafts 19a and 29a. A loop belt 17 is hung on the pulleys 19b and 29b. One end and the other end of the operation cord 5 are connected to the loop belt 17 at positions P1 and P2, respectively. The operation cord 5 passes through the hanger rail 2 from the positions P1 and P2, and is turned by the turning portion 15 provided at the other end of the hanger rail 2 (the left end in FIG. 8A). ), The hanger rail 2 is hung in a loop from the other end.

  The leading runner 3a is connected to the loop belt 17 at the position P1. The leading runner 3 a can be moved in the hanger rail 1 by operating the operation cord 5 that is suspended from the hanger rail 1. For example, when the operation code 5 is pulled down as indicated by arrow B in FIG. 8C, the operation code 5 moves in the direction of arrow B in FIG. 8B. Since the loop belt 17 is connected to the operation cord 5 at the position P2, when the operation cord 5 moves in the direction of arrow B within the hanger rail 1, the loop belt 17 circulates around the pulleys 19b and 29b in the direction of arrow B. To do. Since the leading runner 3a is connected to the loop belt 17 at the position P1, when the position P2 of the loop belt 17 moves in the direction of the arrow B within the hanger rail 1, the leading runner 3a is shown in FIG. Moving to the right, the state shown in FIG. 9 is obtained. In the state shown in FIG. 9, the curtain 11 is substantially fully open, and the separation unit 9 has moved to a position close to the hanger rail 1.

  When the operation cord 5 is pulled down from the state shown in FIG. 9 as indicated by the arrow A in FIG. 9B, the operation cord 5 moves in the direction of the arrow A in FIG. 9A. Since the loop belt 17 is coupled to the operation cord 5 at the position P1, the position P1 of the loop belt 17 moves in the arrow A direction when the operation cord 5 moves in the arrow A direction. Since the leading runner 3a is connected to the loop belt 17 at the position P1, when the loop belt 17 is rotated in the direction of arrow A, the leading runner 3a moves in the direction of arrow A in FIG. The state shown in FIG. 10 is obtained. In the state shown in FIG. 10, the curtain 11 is substantially fully closed, and the separation unit 9 moves to the position indicated by 10 (b).

In the present embodiment, as in the first embodiment, the length of the exposed portion of the operation cord 5 from the hanger rail 1 is equal to or longer than the moving distance of the leading runner 3a when the curtain 11 is opened and closed. The curtain 11 is always located outside the hanger rail 1 when the curtain 11 is opened and closed. According to such a configuration, as in the first embodiment, the user can identify the connection state of the separation unit 9, and reconnect the separated male member 115 and female member 116 at the exposed portion. It becomes easy to return to the original state.
In addition, since the drive system cord (loop belt 17) and the operation system cord (operation code 5) are separated and the operation system cord can be separated, the operation system code is separated and the number of separations is increased. Even if it becomes unusable, the drive system code is alive, so there is no problem with the drive system code.

This embodiment can also be implemented in the following forms.
The guide portions 19 and 29 are constituted by a sliding surface provided on an end cap attached to the end portion of the hanger rail 1, for example, instead of the shaft and the pulley, and the loop belt 17 is slid on the sliding surface. You may make it make the loop belt 17 circulate within the hanger rail 1 by moving.

6). Sixth Embodiment A sixth embodiment of the present invention will be described with reference to FIGS. This embodiment is similar to the fifth embodiment, and is mainly different in that safety is ensured by providing a separating portion 9 between the operation cord 5 and the loop belt 17. Hereinafter, the difference will be mainly described.

  In the present embodiment, as shown in FIG. 12, by engaging the fixing tool 21 and the auxiliary member 23 with the loop belt 17 sandwiched between the fixing tool 21 and the auxiliary member 23, these are moved to the position P <b> 1 of the loop belt 17. Fix against. The fixture 21 includes a base portion 21a, claw portions 21b provided on both side edges of the base portion 21a, and engaging portions 21c provided on the base portion 21a. The engaging portion 21c includes a shaft portion 21c1 and a male portion 21c2, and an engaging groove 21c3 is provided in the shaft portion 21c1. The auxiliary member 23 includes a base portion 23a. The base 23a is provided with a recess 23c. The inner circumferential surface of the loop belt 17 is provided with a continuous irregular shape, and the outer circumferential surfaces of the two pulleys 19b and 29b are also provided with corresponding irregularities so that the loop belt 17 and the pulleys 19b and 29b slide on each other. Therefore, as shown in the seventh embodiment, when at least one of the pulleys 19b and 29b is urged by a spring motor or a spring, the rotational torque of the pulleys 19b and 29b can be transmitted to the loop belt 17. It has become. The loop belt 17 is supported by a belt support rib 1 d formed in the hanger rail 1 so as to protrude from the front and rear inner walls of the hanger rail 1. A plurality of concave portions 23c of the base portion 23a are provided at a pitch engageable with the belt convex portion 17a. By engaging the upper and lower claw portions 21b with the upper and lower side edges 23b of the base portion 23a so that the loop belt 17 is sandwiched between the auxiliary member 23 and the fixture 21 with the convex portion 17a engaged with the concave portion 23c. The fixing tool 21 and the auxiliary member 23 can be fixed to the loop belt 17. Since the fixture 21 is engaged with the notch 17b of the loop belt 17, the lower surface 17c of the loop belt 17 and the lower surface 21d of the fixture 21 other than the notch 17b have substantially the same height. The auxiliary member 23 is provided with an extension 23d. By inserting the extension 23d into an opening (not shown) provided in the leading runner 3a, the leading runner 3a is connected to the loop belt 17. It moves together.

  One end of the operation cord 5 is provided with an engaging portion 5d. The engaging portion 5d includes a pair of arms 5d1 and a claw portion 5d2 provided on the arm 5d1. The arm 5d1 is formed of, for example, a synthetic resin and has elasticity in a direction extending from the engaging portion 21c of the fixture 21. The engaging portion 5d may be outsert-molded and fixed to the operation cord 5, or may be fixed to the operation cord 5 by a method such as knotting or caulking (not shown) after being formed as a separate part. When the engaging portion 5d is pressed against the fixture 21 in the longitudinal direction of the hanger rail 1, the distance between the pair of arms 5d1 increases, and when the claw portion 5d2 gets over the shaft portion 21c1, the claw portion 5d2 contacts the shaft portion 21c1. The engaging portions 5 d and 21 c are engaged in the longitudinal direction of the hanger rail 1. Since the groove width of the engagement groove 21c3 is substantially close to the thickness of the arm 5d1, the engagement portion 5d is also held in the front-rear direction. Relative movement of the engaging portion 5d and the loop belt 17 during the runner moving operation is prevented by the engagement of the engaging portions 5d and 21c. The engaging portions 5d and 21c are substantially at the same height position while being supported by the belt support rib 1d.

  In this embodiment, the separation portion 9 is provided between the operation cord 5 and the loop belt 17, and when an excessive tensile force exceeding a predetermined threshold is applied to the operation cord 5, the distance between the pair of arms 5 d 1 is elastic. The engagement between the engaging portions 5d and 21c is released, and the operation cord 5 is non-looped to ensure safety. Even if the engaging portion 5d is detached from the hanger rail 1 due to non-looping, the other end of the operation cord 5 is jointed to the loop belt 17 at the position P2, so that the operation cord 5 is not lost. . When the engaging portions 5d and 21c are reengaged after the engagement between the engaging portions 5d and 21c is released, first, when the engaging portion 5d is detached from the hanger rail 1 The engaging portion 5 d is inserted into the hanger rail 1 from the introduction port 14 at the end of the hanger rail 1. When the engaging portion 5d is not dropped from the hanger rail 1 or after the engaging portion 5d is inserted from the introduction port 14 at the end of the hanger rail 1, the engaging portion 5d is positioned along the belt support rib 1d. It may be moved in the direction of P1, brought into contact with the fixture 21c of the loop belt 17 and elastically fitted. Accordingly, the original state can be easily restored.

This embodiment can also be implemented in the following aspects.
The engagement portion 5d may have a larger diameter than the gap between the pulley 15 and its guide portion (not shown) so that it does not fall out.
-The engaging part 21c may be provided in the auxiliary member 23, and the engaging part 5d may be disengaged from the extending part 23d.
-The extension part 23d is not provided in the auxiliary member 23, but the leading runner 3a may be fixed to the loop belt 17 by another member, and the auxiliary member 23 may be a belt fixing-dedicated part.
-The notch 17b is not provided in the loop belt 17, but the height of the engaging part 5d from the belt support rib 1d may be increased to match the engaging positions of the engaging part 5d and the engaging part 21c.

7). Seventh Embodiment A seventh embodiment of the present invention will be described with reference to FIGS. This embodiment is similar to the sixth embodiment, and includes a biasing pulley unit 31 in which a pulley is biased by a biasing means instead of the guide portion 29, and the shielding material is unidirectionally driven by a biasing force. The main difference is that it can be moved automatically. Hereinafter, the difference will be mainly described.

  As shown in FIG. 13, the urging pulley unit 31 includes a pulley 39 that is rotatably supported by a pulley case 33, and a drive unit 35 that applies an urging force to the pulley 39 via a transmission shaft 38. The drive unit 35 includes a housing 43, a fixed plug 45, a rotary plug 51, and a torsion coil spring 49. The housing 43 is fixed to the pulley case 33 with a fixing screw 53. The fixed plug 45 is supported by the fixing pin 47 so as not to rotate with respect to the housing 43. The rotary plug 51 is supported so as to rotate integrally with the transmission shaft 38. Since the transmission shaft 38 rotates together with the pulley 39, the pulley 39 and the rotary plug 51 rotate integrally. One end of the torsion coil spring 49 is non-rotatably connected to the fixed plug 45, and the other end is non-rotatably connected to the rotary plug 51.

  With such a configuration, when the opening direction operation portion 5o (shown in FIG. 11C) of the operation cord 5 is pulled down and the pulley 39 is rotated in the opening direction, the rotary plug 51 rotates relative to the fixed plug 45. By doing so, the torsion coil spring 49 is stored. The pulley 39 is biased in the closing direction of the curtain 11 by the stored torsion coil spring 49. By urging the pulley 39, the leading runner 3 a is urged in the closing direction of the curtain 11 via the loop belt 17.

  A cam portion 40 having a substantially semicircular cross section is provided on the bottom surface of the pulley 39. The pulley case 33 includes a slide groove 41 having a substantially semicircular cross section on the surface facing the cam portion 40. A clutch ball 55 is disposed between the cam portion 40 and the slide groove 41. The clutch ball 55 is movable along the slide groove 41. The cam portion 40 is constituted by the cam portion 40, the slide groove 41, and the clutch ball 55.

  As shown in FIG. 14A, the cam portion 40 includes an outer groove 40o, an inner groove 40i, a release groove 40r, a retracting groove 40s, and a pocket 40p. The clutch ball 55 relatively moves along each groove of the cam portion 40 while moving along the slide groove 55. Hereinafter, the relative movement of the clutch ball 55 with respect to each groove of the cam portion 40 is also simply referred to as “movement”.

  In the stop state in which the operation cord 5 is not operated with the curtain 11 partially or completely open, as will be described later, the clutch ball 55 is guided to the pocket 40p, as shown in FIG. The state where the clutch ball 55 is in the pocket 40p is the initial state. In this state, since the pulley 39 is biased in the closing direction, the clutch ball 55 is locked by the pocket 40p. For this reason, the pulley 39 does not rotate and the opening of the curtain 11 is maintained. From this state, when the opening direction operation portion 5o of the operation cord 5 is pulled down short and the pulley 39 is rotated in the opening direction as shown in FIG. 14C, the clutch ball 55 is moved along the release groove 40r to the outer groove. When the pulley 39 moves toward 40o and the rotation angle of the pulley 39 becomes R or more, the clutch ball 55 enters the outer groove 40o beyond the outer groove boundary OB. When the operation cord 5 is released in this state, the pulley 39 is rotated in the closing direction by the urging force. At this time, as indicated by an arrow in the outer groove 40o in FIG. 14C, the clutch ball 55 moves along the outer groove 40o and does not enter the pocket 40p. For this reason, the curtain 11 automatically moves in the closing direction without stopping.

  In addition, when a long pulling operation is performed on the opening direction operation portion 5o of the operation cord 5 from the state of FIG. 14B, the clutch ball 55 in the pocket 40p is moved along with the rotation of the pulley 39 in the opening direction. As shown by the arrow A1 in FIG. 14D, it moves to the outer groove 40o through the release groove 40r. When the pulley 39 is further rotated in the opening direction, the clutch ball 55 is guided to the drawing groove 40s by the guide wall 40g. When the rotation angle of the pulley 39 becomes S or more, the clutch ball 55 reaches the inner groove 40i beyond the inner groove boundary IB. When the pulley 39 is further rotated in the opening direction in this state, the clutch ball 55 moves along the inner groove 40i and does not enter the pocket 40p. For this reason, the movement of the curtain 11 in the opening direction is not hindered.

  When the operation cord 5 is released while the clutch ball 55 is in the inner groove 40i, the pulley 39 is rotated in the closing direction, and the clutch ball 55 moves toward the pocket 40p as indicated by an arrow A3 along with the rotation. Then, as shown in FIG. 14 (b), it is locked by the pocket 40p. For this reason, the curtain 11 does not automatically move in the closing direction. In this manner, when the operation cord 5 is released after performing a long pulling operation on the opening direction operation portion 5o of the operation cord 5, the opening of the curtain 11 can be maintained at a predetermined position.

  In this way, the locked state and unlocked state of the rotation of the pulley 39 can be switched using only the opening direction operation portion 5o of the operation cord 5. When pulling down the operation portion 5o in the opening direction of the operation cord 5, a pulling force against the urging force is applied to the position P2 in FIG. 11B. At this position, the operation cord 5 can be separated from the loop belt 17. Since it is not configured, the operation cord 5 is not separated from the loop belt 17. In the position P1 of FIG. 11 (b), since the separation part 9 is provided between the operation cord 5 and the loop belt 17, in an emergency, the operation code 5 is separated from the loop belt 17 in the separation part 9, and safety is ensured. Secured.

This embodiment can also be implemented in the following aspects.
As the urging means for the pulley 39, another urging means such as a spring may be employed instead of the torsion coil spring. Even if a biasing force is directly applied to the loop belt 17 by directly connecting a tension spring to the loop belt 17 and pulling it from the end of the hanger rail 1 or attaching a cord connected to a weight to the loop belt 17. Good. Further, an urging force may be directly applied to the leading runner 3a and the operation cord 5. In any case, a biasing force that moves the leading runner 3a in one direction is applied directly or indirectly.

The semi-automatic closing operation may be performed by urging the leading runner 3a in the opening direction of the curtain 11. In that case, the closing direction operation portion 5s (illustrated in FIG. 11C) of the operation cord 5 is operated to switch between the rotation locked state and the unlocked state of the pulley 39. Further, it is preferable to provide the separation portion 9 on the position P2 side where no tensile force is applied so that the operation cord 5 is not separated from the loop belt 17 when the operation direction 5s of the operation cord 5 is operated. Examples of the separation unit 9 include those shown in the first embodiment and the sixth embodiment.

-The shape of the cam part 40 shown in FIG. 14 is an illustration, and another structure which has the same function may be sufficient. For example, the configuration may include a first groove and a second groove that are separated from each other in the radial direction and extend in the circumferential direction of the pulley, and a pull-in groove and a pocket that are disposed between the first and second grooves. The lead-in groove and the pocket are arranged at positions separated in the circumferential direction. The first groove is provided with a guide wall that guides the clutch ball in the first groove to the drawing groove. In addition, a release groove extending from the pocket toward the first groove is provided. The first groove may be either inside or outside in the radial direction with respect to the second groove. Moreover, you may provide a pocket in the multiple places of the circumferential direction.

The cam portion 40 may be provided on the pulley case 33 and the slide groove 41 may be provided on the pulley 39. In addition, since the clutch portion can be provided in any interlocking rotating body that rotates in conjunction with the movement of the leading runner 3a, if there is an interlocking rotating body other than the pulley 39, the clutch portion is attached to the interlocking rotating body. It may be provided. The clutch part provided in the interlocking rotating body is configured to generate a holding torque necessary for stopping the movement of the leading runner 3a.

The configuration of the urging means and the clutch unit described in the present embodiment can be applied to an operating device that does not have a loop body as in the first to fourth embodiments and the operation cord is hooked on the pulley. is there.

-From another viewpoint, this invention can be grasped | ascertained as an operating device of the shielding apparatus which can operate a shielding material semiautomatically by said biasing means and a clutch part. From this viewpoint, the separation unit 9 is not always necessary.
