  In the guide ring for the lifting / lowering cord according to the first aspect of the present invention, the lifting / lowering cord is loosely inserted into the guide ring fitted into the uppermost loop ring of the shielding member, that is, the inner ring portion of the uppermost guide ring. A lifting / lowering cord is loosely inserted into a guide ring fitted to a loop ring other than the uppermost loop ring, that is, an outer ring portion of a guide ring other than the uppermost guide ring, and the lifting / lowering cord is detached from the outer ring portion by a cord releasing mechanism. Since the lifting / lowering cord is not easily detached from the inner ring part of the uppermost guide ring, it can be relatively easily removed from the outer ring part of the guide ring other than the uppermost guide ring via the cord removal mechanism. break away. As a result, it is possible to prevent the lifting / lowering cord loosely inserted into the inner ring portion of the uppermost guide ring from being unintentionally detached from the guide ring due to an impact caused by a collision with other parts when the shielding material is folded up. When a load is applied to the lifting / lowering cords loosely inserted into the outer ring portion of the guide ring other than the uppermost guide ring, the lifting / lowering cords can be detached from these guide rings.

  In the lifting cord guide ring according to the second aspect of the present invention, the lifting cord is loosely inserted into the insertion ring portion of the uppermost guide ring, and the lifting cord is loosely inserted into the loose insertion ring portion of the guide ring other than the uppermost guide ring. In addition, the cord detachment mechanism is configured so that the lifting / lowering cord can be detached from the loose ring, so that the lifting / lowering cord does not easily detach from the fitting ring portion of the uppermost guide ring, but a guide other than the uppermost guide ring. It detaches relatively easily from the loose insertion ring portion of the ring via a cord detachment mechanism. As a result, it is possible to prevent the lifting / lowering cord loosely inserted into the fitting ring portion of the uppermost guide ring from dropping unintentionally from the guide ring due to an impact caused by a collision with other parts when the shielding material is folded up. When a load is applied to the lifting / lowering cords loosely inserted in the loose insertion ring portions of the guide rings other than the uppermost guide ring, the lifting / lowering cords can be detached from these guide rings. Further, since the lifting / lowering cord is loosely inserted into the insertion ring portion of the uppermost guide ring, the inner ring portion can be dispensed with. As a result, the guide ring can be reduced in size. Furthermore, since the insertion notch is formed in the insertion ring, the insertion ring of the uppermost guide ring is inserted into the loop ring from the insertion notch and the lifting cord is inserted into the insertion ring of the uppermost guide ring. It can be loosely inserted from the notch. As a result, the insertion ring portion of the uppermost guide ring can be easily inserted into the loop ring, and the lifting / lowering cord can be easily loosely inserted into the insertion ring portion of the uppermost guide ring.

  In the lifting cord guide ring according to the third aspect of the present invention, the cord detaching mechanism of the guide ring has a clearance narrower than the diameter of the lifting cord or is a notch for separation with no clearance. The pair of arms formed in the outer ring part or loose insertion ring part by the notch for detachment of the guide ring other than the uppermost guide ring is elastic when a load exceeding the predetermined value in the direction away from As a result of the deformation, the detachment notch is pushed out by the lifting cord. As a result, the lifting / lowering cord can be reliably detached from the guide rings other than the uppermost guide ring.

  In the guide ring for the lifting / lowering cord according to the fourth aspect of the present invention, when a load of a predetermined value or more in the direction separating the lifting / lowering cord from the shielding material acts on the lifting / lowering cord, a pair of guide rings other than the uppermost guide ring is used. The arm is elastically deformed, the projection is detached from the recess, and the notch is further pushed out by the lifting cord, so that the lifting cord is quickly detached from the outer ring portion of the guide ring. As a result, it is possible to prevent damage to the components of the roman shade, and it is possible to quickly release a child, an elderly person, or the like that contacts the lifting cord. Also, during normal lifting operation of the lifting / lowering cord guided by the guide ring along the shielding material, the lifting / lowering cord does not easily detach from the outer ring portion of the guide ring other than the uppermost guide ring, and the lifting / lowering cord The elevating cord can be raised and lowered smoothly without biting into the cutout portion of the outer ring portion. Further, not only is a notch formed in the outer ring part, but also a recess is provided with a protrusion projecting from one arm tip of the pair of arms of the outer ring part and releasably engaging the other arm tip. Since it is formed, the minimum value of the load when the lifting / lowering cord is detached from the loose insertion ring portion can be set relatively accurately by adjusting the engagement state of the protrusion with the concave portion.

  In the lifting cord guide ring according to the fifth aspect of the present invention, since the plane including the loose insertion ring portion is configured to coincide with the plane including the insertion ring portion, the loop ring is positioned in the vertical plane. This guide ring can be applied to the shielding material. That is, the lifting / lowering cord can be smoothly inserted into the loose insertion ring portion in a state where the insertion ring portion is fitted into the loop ring. The lifting cord is guided by the guide ring along the shielding material and moves up and down smoothly.

  In the lifting cord guide ring according to the sixth aspect of the present invention, the plane including the loose insertion ring portion passes through the center of each ring hole of the insertion ring portion and the loose insertion ring portion with respect to the plane including the insertion ring portion. The guide ring can be applied to a sharp-style shielding material in which a loop ring is positioned in a horizontal plane because it is configured to rotate around a straight line and be orthogonal. That is, the lifting / lowering cord can be smoothly inserted into the loose insertion ring portion in a state where the insertion ring portion is fitted into the loop ring. The lifting cord is guided by the guide ring along the shielding material and moves up and down smoothly.

  In the lifting cord guide ring according to the seventh aspect of the present invention, the fitting ring portion of the guide ring can be fitted into the loop ring from the fitting notch, so that the fitting ring portion of the guide ring can be easily fitted into the loop ring. The lifting / lowering cord can be loosely inserted directly into the inner ring of the uppermost guide ring from the notch for loose insertion, or the lifting / lowering cord can be inserted once into the insertion ring of the uppermost guide ring from the notch for insertion. Since the ring portion can be loosely inserted from the notch for loose insertion, the lifting / lowering cord can be loosely inserted into the inner ring portion of the uppermost guide ring easily or relatively easily.

When the lifting / lowering cord 13 is guided by the plurality of guide rings 80 attached to 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 is not easily detached from the loose insertion ring portion 82. The elevating cord 13 can be raised and lowered relatively smoothly. Further, since the lifting / lowering cord 13 is loosely inserted into the insertion ring portion 81 of the uppermost guide ring 80, the lifting / lowering cord 13 does not easily detach from the insertion ring portion 81 of the uppermost guide ring 80. As a result, the lifting / lowering cord 13 loosely inserted in the fitting ring portion 81 of the uppermost guide ring 80 is unintentionally detached from the guide ring 80 due to an impact caused by a collision with other parts when the shielding member 11 is folded up. Can be prevented. Moreover, since the lifting / lowering cord 13 is loosely inserted into the fitting ring portion 81 of the uppermost guide ring 80, the inner ring portion of the first embodiment can be dispensed with. As a result, the guide ring 80 can be made smaller than in the first embodiment. Further, since the lifting / lowering cord 13 is loosely inserted into the loose insertion ring portion 82 of the guide ring 80 other than the uppermost guide ring 80, 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. When acted, the pair of arms 82b and 82c formed on the loose insertion ring portion 82 of the guide ring 80 other than the uppermost guide ring 80 is elastically deformed, and the detachable cutout portion 86 is expanded by the lifting / lowering cord 13.
