(3) The front ends of the rotation fulcrum portions 27a and 27b can be crimped to the upper end portion of the inner side surface of the frame 1. Since the frame 1 is opened downward, it is easy to ensure the dimensional accuracy of the interval of the upper portion of the inner side surface, and it is less likely to cause plastic deformation due to the crimping force. Thus, the lifting cord winding device 5 can be stably fixed to the frame 1.

(4) The front ends of the rotation fulcrum portions 27a and 27b are press-contacted to the upper end portion of the inner side surface of the frame 1 by the elastic action of the crimping member 24, so that the size between the inner surfaces of the frame 1 is sufficiently ensured as long as the height of the projections 31 is sufficiently ensured. Slightly biased The lift cord winding device 5 can also be stably fixed by the difference.

(5) Since the crimping member 24 is formed of a metal having elasticity, it is less likely to cause deterioration of the pressure contact force over time.

(6) By pressing the operation piece 32 exposed to the opening of the frame 1, the engagement portion 25 of the pressure contact member 24 can be hooked on the holding portion 35 of the elastic piece 34. Therefore, the fixing operation of the lifting cord winding device 5 housed in the frame 1 can be easily performed without a tool.

(7) By pressing the elastic piece 34 exposed to the opening of the frame 1 upward, the engagement portion 25 can be detached from the holding portion 35. Therefore, the fixing release operation of the lifting cord winding device 5 housed in the frame 1 can be easily performed without a tool.

The above embodiment can also adopt the following embodiments.

The lifting rope winding device is not limited to the pull-up type curtain, and can be implemented by fixing the lifting cord winding device of the pleated curtain to the frame, and fixing any component to the curtain rail.

Further, in a state in which the weight s2 of the curtain blank s2 is prevented from falling, the chain s13 is slightly rotated in the direction of pulling the curtain blank s2, and the operation of the stopper s16 is released, and the curtain blank s2 is lowered by its own weight.

Next, a specific configuration of the operation device s11a will be described with reference to Figs. 9, 11, and 12. As shown in FIGS. 9 and 11, the operation device s11a mounts the intermediate plate s19 and the case cover s20 on the distal end side of the casing s18. And, the casing s18, the intermediate plate s19, and the casing cover s20 are in the front and rear direction of the roll-up curtain It is formed in line symmetry.

The pulley s12 is rotatably supported in a support shaft s21 formed on the inner surface of the casing cover s20, and the torque limiter s14 is disposed inside the pulley s12. Further, when the pulley s12 is rotated by operating the ball chain s13, the output gear s22 of the torque limiter s14 normally rotates.

Further, the torque limiter s14 is set to not transmit a rotational torque that exceeds a predetermined value to the output gear s22, and if the torque acts on the pulley s12, the pulley s12 idles with respect to the output gear s22.

The output gear s22 is meshed with a transmission gear s23 that is rotatably supported on the intermediate plate s19. Thereby, the transmission gear s23 rotates in accordance with the rotation of the output gear s22. In the casing s18, a cylindrical portion s24 that protrudes toward the frame s1 is formed on the base end surface, and the clutch device s15a is housed in the tubular portion s24. The input shaft s25 of the clutch device s15a is fitted to the center portion of the transmission gear s23 so as to be relatively rotatable, and the end portion of the drive shaft s10 is fitted to the output shaft s26 of the clutch device s15a so as to be relatively rotatable.

Further, the clutch device s15a operates as follows: the rotation of the transmission gear s23 is transmitted to the drive shaft s10, and the rotational torque of the lift cord winding device s5 acting on the drive shaft s10 is not transmitted to the transmission gear s23.

As shown in FIGS. 11 and 12, the tubular portion s24 of the casing s18 can be inserted into the frame s1, and is placed in the casing s18 and the intermediate plate s19 in a state in which the tubular portion s24 is inserted into the frame s1. Upper insertion holes s27, s28 The tapping screw s30 is screwed into the rib s29 on the upper portion of the frame s1, and the casing s18 is fixed to the frame s1.

Next, the action of the pull-up type curtain having the structure as described above will be explained. In the pull-up type curtain for right operation shown in FIG. 8, for example, when the ball chain s13 which hangs down from the pulley s12 to the indoor side is pulled downward, the rotation of the pulley is transmitted to the drive shaft s10 via the clutch device s15a, and the pull-up is pulled up. The rope s6 is wound onto the lifting rope winding device s5, and the curtain blank s2 is lifted.

After the curtain blank s2 is lifted to the desired height, when the ball chain s13 is released, the curtain blank s2 is kept at a desired height by the operation of the stopper device s16, which prevents the curtain blank s2 from falling due to its own weight.

From this state, the ball chain s13 is slightly pulled in the lifting direction of the curtain blank s2, and then the hand is released, the operation of the stopper device s16 is released, and the curtain blank s2 is lowered by its own weight. At this time, the drive shaft s10 rotates in the rewinding direction of the elevating rope, but the rotation of the drive shaft s10 is not transmitted to the transmission gear s23 due to the action of the clutch device s15a. Thereby, the ball chain s13 does not rotate.

When the clutch device s15a of the operating device s11a is replaced by the clutch device s15b, the operating device s11b for the left operation is configured. When the operation device s11b is attached to the left end of the frame s1 as shown in Fig. 13, and the ball chain s13 hanging from the pulley s12 toward the indoor side is pulled downward, the rotation of the pulley It is transmitted to the drive shaft s10 via the clutch device s15b, and the lift cord s6 is wound onto the lift cord winding device s5, and the curtain blank s2 is lifted.

After the curtain blank s2 is lifted to the desired height, the ball chain s13 is released, and the curtain blank s2 is prevented from falling due to its own weight due to the operation of the stopper device s16, and the curtain blank s2 is maintained at a desired height.

From this state, the ball chain s13 is slightly pulled in the pulling direction of the curtain blank s2, and then the hand is released, the operation of the stopper s16 is released, and the curtain blank s2 is lowered by its own weight. At this time, the drive shaft s10 rotates in the rewinding direction of the elevating rope, but the rotation of the drive shaft s10 is not transmitted to the transmission gear s23 due to the action of the clutch device s15b. Thereby, the ball chain s13 does not rotate.

The operation devices s11a and s11b of the pull-up blinds configured as described above can obtain the effects described below.

(1) When the curtain blank s2 is lowered by its own weight, the ball chain s13 can be prevented from rotating.
