<First Embodiment>
As shown in FIG. 3, the roman shade 10 includes a head rail 12 attached to a wall surface or ceiling of a room via a fixing bracket (not shown), and an upper end attached to the head rail 12. The shield member 11 has the same width, and the lifting / lowering cord 13 that is suspended from the head rail 12 so as to be lifted and that has a lower end connected to a lower portion of the shield member 11. The shielding material 11 is formed of a cloth, a screen or the like. In this embodiment, the shielding material 11 is a plain-style shielding material. A plurality of tapes 11a are sewn on the back surface of the plain-style shielding material 11 with a predetermined interval in the horizontal direction and extending in the vertical direction, and the loop ring with a predetermined interval in the vertical direction is sewn to these tapes 11a. 11b (FIGS. 1 and 2) are provided. The plurality of tapes 11a are sewn to the back surface of the shielding material 11 so as to face a lifting cord 13 suspended from a cord insertion member 14 described later in the head rail 12. The loop ring 11b is formed so as to be positioned in the vertical plane, that is, a ring that is curved in the vertical plane is formed.

  The head rail 12 has a rail body 12a made by extrusion or pultrusion of a metal such as an aluminum alloy, and lid bodies 12b provided at both ends of the rail body 12a (FIG. 3). In the internal space of the head rail 12, a plurality of cord insertion members 14 are accommodated at arbitrary positions in the longitudinal direction of the head rail 12. Further, a number of lifting / lowering cords 13 corresponding to the number of cord insertion members 14 are inserted into the internal space of the head rail 12, and one end portion of these lifting / lowering cords 13 is shielded from a corresponding predetermined cord insertion member 14. 11 hangs down along the back surface. In addition, the code | symbol 16 in FIG. 3 is the weight bar provided in the lower edge of the shielding material 11. FIG.

  On the other hand, among the plurality of loop rings 11b (FIGS. 1 and 2) provided at predetermined intervals in the vertical direction along the tape 11a, the plurality of loop rings excluding the lowermost loop ring include an elevating cord 13. A guide ring 20 is attached, and a cord locking member 30 is attached to the lowermost loop ring (FIG. 3). The guide ring 20 includes an insertion ring portion 21 that is inserted into the loop ring 11b, and a loose insertion ring portion 22 that is provided integrally with the insertion ring portion 21 and into which the elevating cord 13 is loosely inserted.

  A plane including the loose insertion ring portion 22 is configured to coincide with a plane including the insertion ring portion 21 (FIGS. 1 and 2). The loose insertion portion 22 has a notch 22a. The notch 22a is on a straight line passing through the center of each ring hole of the insertion ring portion 21 and the loose insertion ring portion 22 in the loose insertion ring portion 22, and a connection portion between the insertion ring portion 21 and the loose insertion ring portion 22. Are formed on the opposite side. The formation of the notch 22a divides the loose insertion ring 22 into a pair of arms 22b and 22c. A protrusion 22d protrudes from the tip of one arm 22b of the pair of arms 22b and 22c, and a recess 22e is formed at the tip of the other arm 22c so that the protrusion 22d is detachably engaged. Specifically, the first thin portion 22f is formed by removing one surface of the tip of one arm 22b so that the thickness thereof is halved, and one of the first thin portions 22f is removed. The projection 22d is provided on the surface. Further, the other thin portion 22g is formed by removing the other surface of the other arm 22c so that the thickness thereof is halved, and the second thin portion 22g is formed in a substantially C shape. A recess 22e is provided. When a load of a predetermined value or more in the direction separating the lifting / lowering cord 13 from the shielding material 11 is applied to the lifting / lowering cord 13, the pair of arms 22b and 22c are elastically deformed, and the projection 22d is detached from the recess 22e and further cut away. 22 a is configured to be expanded by the lifting / lowering cord 13.

  In addition, the code | symbol 21a in FIG.1 and FIG.2 is the insertion port formed by notching a part of insertion ring part 21 in order to insert the insertion ring part 21 in the loop ring 11b. Although this insertion port 21a can easily insert the insertion ring portion 21 into the loop ring 11b, the insertion ring portion 21 once inserted into the loop ring 11b cannot be easily detached from the loop ring 11b. Moreover, the said insertion ring part 21 and the loose insertion ring part 22 are integrally formed by plastics, such as a polycarbonate.

  The cord locking tool 30 (FIG. 3) attached to the lowermost loop ring includes a first member attached to the lowermost loop ring (not shown), and a second member for locking one end of the lifting / lowering cord 13. And a coupling member that removably couples the first member and the second member. And when the load more than predetermined value acts on the raising / lowering cord 13, it is comprised so that a 1st member may detach | leave from a 2nd member and the one end part of the raising / lowering cord 13 may detach | leave from the shield 11. FIG.

  On the other hand, the other end portions of the plurality of lifting cords 13 inserted into the inner space of the head rail 12 are guided to the inner space of the head rail 12 in one direction (leftward in FIG. 3) and After being inserted into a stopper (not shown) which is a provided stopping means, the head is suspended from the end of the head rail 12 and connected to the operation knob 31. The stopper is configured to prohibit or allow the raising of the lifting / lowering cord 13 on the side where the operation knob 31 is provided (the operation knob 31 side). Specifically, when the stopper is raised after the lifting / lowering cord 13 on the operation knob 31 is lowered, the stopper prohibits the lifting of the lifting / lowering cord 13 on the operation knob 31 side. Once the lifting / lowering cord 13 is lowered, the lifting / lowering cord 13 is allowed to rise again. Here, reference numeral 31 a in FIG. 3 is a connecting string that connects the operation knob 31 to the lower end of the shielding material 11.

  One end side of the lifting / lowering cord 13 suspended from the cord insertion member 14 built in the head rail 12 is connected to the loose insertion ring portions 22 of the plurality of guide rings 20 attached to the back surface of the shielding member 11 via the loop ring 11b. After being inserted and routed vertically downward, it is connected to a cord locking tool 30 attached to the lower end of the shielding material 11 via a loop ring (FIG. 3). As a result, when the lifting / lowering cord 13 on the operation knob 31 side is raised, the lifting / lowering cord 13 on the side (shielding material 11 side) suspended from the cord insertion member 14 of the head rail 12 and connected to the shielding material 11 is lowered, and vice versa. When the lifting / lowering cord 13 on the operation knob 31 side is lowered, the lifting / lowering cord 13 on the shielding material 11 side rises so that the shielding material 11 can be lifted and folded.

  The usage method of the guide ring 20 for the raising / lowering cord 13 of the shielding material 11 comprised in this way is demonstrated. The insertion ring portion 21 of the guide ring 20 is inserted into the plurality of loop rings 11b excluding the lowermost loop ring among the plurality of loop rings 11b provided on the back surface of the plain-style shielding material 11. It inserts from the mouth 21a. At this time, since the loop ring 11b is positioned in the vertical plane, the fitting ring portion 21 and the loose insertion ring portion 22 of the guide ring 20 are positioned in the horizontal plane (FIGS. 1 and 2). Accordingly, the lifting / lowering cord 13 extending in the vertical direction can be smoothly loosely inserted into the loose insertion ring portions 22 of the plurality of guide rings 20 attached to the back surface of the shielding member 11 with a predetermined interval in the vertical direction. And the one end part of the raising / lowering cord 13 is latched by the cord latching tool 30 attached to the loop ring of the lowest end.

  Thus, when the lifting / lowering cord 13 is guided by the guide ring 20 attached along the back surface of the shielding member 11, that is, during the normal lifting / lowering operation of the lifting / lowering cord 13, the lifting / lowering cord 13 can be easily removed from the loose insertion ring portion 22. The lifting / lowering cord 13 can be lifted / lowered smoothly without the lifting / lowering cord 13 being cut into the notch 22a of the loose insertion ring 22. On the other hand, when a load greater than or equal to a predetermined value in the direction in which the lifting / lowering cord 13 is separated from the shielding material 11 acts on the lifting / lowering cord 13, the pair of arms 22b and 22c of the guide ring 20 is elastically deformed, and the protrusion 22d extends from the recess 22e. Since it is separated and the notch portion 22 a is further spread by the lifting / lowering cord 13, the lifting / lowering cord 13 is quickly detached from the loose insertion ring portion 22. As a result, damage to the components of the roman shade 10 can be prevented, and children, elderly people, etc. that have come into contact with the lifting cord 13 can be released quickly. Further, not only the notch portion 22a is formed in the loose insertion ring portion 22 of the guide ring 20, but also a projection 22d is projected from the tip of one arm 22b of the pair of arms 22b, 22c and the other Since the recess 22e in which the projection 22d is detachably engaged is formed at the tip of the arm 22c of the arm 22c, the lifting cord 13 is detached from the loose insertion ring portion 22 by adjusting the engagement state of the projection 22d with the recess 22e. The minimum load value (for example, about 1 kg) can be set relatively accurately.

<Second Embodiment>
4 to 6 show a second embodiment of the present invention. 4 to 6, the same reference numerals as those in FIGS. 1 to 3 denote the same components. In this embodiment, the guide ring 60 is inserted into a loop ring 51b attached to the shielding member 51, and a loose insertion in which the lifting / lowering cord 13 is loosely provided integrally with the insertion ring part 61. The plane including the ring part 62 and the plane including the ring ring part 62 is centered on a straight line passing through the center of each ring hole of the ring ring part 61 and the ring ring part 62 with respect to the plane including the ring ring part 61. It is configured to rotate and be orthogonal (FIGS. 4 and 5). In this embodiment, the shielding material 51 is a sharp-style shielding material (FIG. 6). A plurality of tapes 51a are sewn on the back surface of the sharp-style shielding material 51 with a predetermined interval in the vertical direction and extending in the horizontal direction. Rings 51b (FIGS. 4 and 5) are respectively provided. These loop rings 51b are formed so as to be positioned in a horizontal plane, that is, a ring that is curved in the horizontal plane is formed.

  On the other hand, among the plurality of loop rings 51b (FIG. 6) provided at predetermined intervals in the vertical direction for each tape 51a, a guide for guiding the lifting / lowering cord 13 is provided to a plurality of loop rings excluding the lowermost loop ring. The ring 60 is attached, and the cord locking member 30 is attached to the lowermost loop ring. Further, one end side of the lifting / lowering cord 13 suspended from the cord insertion member 14 built in the head rail 12 is a loose insertion ring portion of a plurality of guide rings 60 attached to the back surface of the shielding member 11 via a loop ring 51b. After being inserted through 62 and routed vertically downward, it is connected to a cord locking tool 30 attached to the lower end of the shielding member 51 via a loop ring (FIG. 6). As a result, when the lifting / lowering cord 13 on the operation knob 31 side is raised, the lifting / lowering cord 13 on the side (shielding material 51 side) that is suspended from the cord insertion member 14 of the head rail 12 and connected to the shielding material 51 is lowered. When the lifting / lowering cord 13 on the operation knob 31 side is lowered, the lifting / lowering cord 13 on the shielding member 51 side rises so that the shielding member 51 can be lifted and folded. The configuration other than the above is the same as that of the first embodiment.

  The usage method of the guide ring 60 for the raising / lowering cord 13 of the shielding material 51 comprised in this way is demonstrated. The insertion ring portion 61 of the guide ring 60 is inserted into the plurality of loop rings 51b excluding the lowermost loop ring among the plurality of loop rings 51b provided on the back surface of the sharp-style shielding material 51. It inserts from the opening 61a. At this time, since the loop ring 51b is positioned in the horizontal plane, the insertion ring portion 61 inserted into the loop ring 51b is positioned in the vertical plane, and the loose insertion ring portion 62 orthogonal to the insertion ring portion 61 is in the horizontal plane. Located (FIGS. 1 and 2). As a result, the elevating cord 13 extending in the vertical direction can be smoothly loosely inserted into the loosely inserted ring portions 62 of the plurality of guide rings 60 attached to the back surface of the shielding member 51 at a predetermined interval in the vertical direction. And the one end part of the raising / lowering cord 13 is latched by the cord latching tool 30 attached to the loop ring of the lowest end.

  Thus, when the lifting / lowering cord 13 is guided by the guide ring 60 attached along the back surface of the shielding member 51, that is, during the normal lifting / lowering operation of the lifting / lowering cord 13, the lifting / lowering cord 13 can be easily removed from the loose insertion ring portion 62. The lifting / lowering cord 13 can be lifted / lowered smoothly without the lifting / lowering cord 13 being bitten into the notch 62a of the loose insertion ring 62. On the other hand, when a load greater than or equal to a predetermined value in the direction separating the lifting / lowering cord 13 from the shielding material 51 is applied to the lifting / lowering cord 13, the pair of arms 22b and 22c of the guide ring 60 is elastically deformed, and the projection 22d extends from the recess 22e. Since it is separated and the notch 22a is further expanded by the lifting / lowering cord 13, the lifting / lowering cord 13 is quickly detached from the loose insertion ring 62. As a result, damage to the components of the roman shade 50 can be prevented, and children, elderly people, etc. that have come into contact with the elevating cord 13 can be quickly released. Further, not only the notch portion 22a is formed in the loose insertion ring portion 62, but also a protrusion 22d is provided at the tip end of one arm 22b of the pair of arms 22b, 22c of the loose insertion ring portion 62 and the tip end of the other arm 22c. Since the recess 22e in which the protrusion 22d is releasably engaged is formed on the upper and lower ends, the minimum value of the load when the lifting / lowering cord 13 is detached from the loose ring portion 62 is adjusted by adjusting the engagement state of the protrusion 22d with the recess 22e. (For example, about 1 kg) can be set relatively accurately.
