In the frame, a lifting / lowering cord winding device is disposed, and an operating device with an operating chain hanging down is attached to one end of the frame. The drive shaft is rotated via the operation device by operating the operation chain, and the curtain fabric can be raised and lowered based on the rotation of the drive shaft.

In the above-described curtain, the lifting / lowering cord winding device is fixed to the frame with a fixing screw, or as disclosed in Patent Document 1, the fixing bracket provided on the bearing member of the lifting / lowering cord winding device is rotated. By moving it, it is fixed to the frame.

Also, a fixing device for fixing the lifting / lowering cord winding device to the frame using the elasticity of synthetic resin has been proposed. In particular, in the case of a raised curtain where the curtain fabric is attached to the frame at the installation site, in order to insert the lifting / lowering cord through the guide ring attached to the back surface of the curtain fabric, the fixing position of the lifting / lowering cord winding device is fixed to the frame. It is necessary to adjust in the longitudinal direction. Therefore, in order to fix the lifting / lowering cord winding device at a desired position of the frame, the fixing screw and the fixing bracket as described above are used.

(About solar shading device)
In the hoisting curtain for fixing the bearing member of the lifting / lowering cord winding device with a fixing screw, a tool such as a screwdriver is required for the fixing operation, and the operation of screwing the fixing screw from below the frame is complicated.

In the fixing device that fixes the lifting / lowering cord winding device to the frame using the elasticity of the synthetic resin, the holding force deteriorates with time due to plastic deformation of the synthetic resin, and therefore the lifting / lowering cord winding device cannot be stably fixed. .

The fixing device disclosed in Patent Document 1 has a configuration in which the fixing member is brought into contact with the vicinity of the opening of the frame and the bearing member is pressed against the ceiling surface in the frame.

Next, a specific configuration of the lifting / lowering cord winding device 5 will be described with reference to FIGS. As shown in FIG. 4, the frame 1 is formed of a substantially rectangular tube-shaped member having an opening that opens downward. The support member 8 is made of a synthetic resin having elasticity, and is formed into a shape that can be inserted into the frame 1 from the side of the frame 1, and both longitudinal ends thereof are longer than the frame 1 in the longitudinal direction of the frame 1. It is held movably only in the direction. Further, bearing

portions

20 a and 20 b are formed at both ends in the longitudinal direction of the support member 8.

The winding shaft 9 is formed so that the diameter gradually decreases from one end to the other end, and shaft portions 21 are formed at both ends thereof. The shaft portion 21 is rotatably supported by a bearing hole 18 formed in the bearing portion 20a and a bearing groove 19 formed in the bearing portion 20b.

Further, a pair of protrusions 19 a for holding the shaft portion 21 in the bearing groove 19 are provided on the inner surface of the bearing groove 19 so as to face each other. On the other end side of the winding shaft 9, a latching portion 22 that latches the upper end of the lifting / lowering cord 6 is formed. An upper end of the lifting / lowering cord 6 is attached to the latching portion 22, passes through the outer peripheral surface of the winding shaft 9, and is suspended downward from a guide portion 23 provided at one end portion of the support member 8. Yes.

When the winding shaft 9 is rotated in the lifting / lowering cord winding direction, the lifting / lowering cord 6 is wound around the large-diameter side of the winding shaft 9 and is sequentially fed toward the small-diameter side so as to be wound spirally. . A pressure contact member 24 is attached to the other end of the support member 8 to fix the support member 8 in the frame 1 so as not to move. The pressure contact member 24 is formed by bending a metal wire that is elastically deformed in a deformable region.

That is, a rectangular locking portion 25 is formed by bending an intermediate portion of one wire, and the wire extending on both sides of the locking portion 25 is bent at a right angle in the same direction at a position near the locking portion 25.

Parallel portions

26a and 26b are formed.

The

parallel portions

parallel portions

26a and 26b are bent at right angles in the direction away from each other. Rotating

fulcrum portions

27a and 27b are formed.

Support grooves 28a and 28b are formed at the upper end of the bearing portion 20b on the other end side of the support member 8 so that the

Then, when the operation piece 32 is bent in the arrow A direction from the state shown in FIG. 6, the locking portion 25 of the pressure contact member 24 rotates in the same direction with the support grooves 28a and 28b as the rotation fulcrum, and FIG. As shown, the locking portion 25 is held by the holding portion 35.

When the elastic piece 34 is pressed upward, that is, in the direction of arrow B shown in FIG. 3, the tip of the elastic piece 34 is bent upward due to the elasticity of the synthetic resin so that the locking portion 25 is detached from the holding portion 35.

When the pressure contact member 24 is rotated in the direction of arrow A by the operation of the operation piece 32 from the state shown in FIGS. 6 and 7, the

parallel portions

26 a and 26 b of the pressure contact member 24 are inclined surfaces 29. Ride on the protrusion 31 and the interval is increased.

Then, as shown in FIG. 4, the

rotation fulcrum portions

27a and 27b move away from each other, that is, in the directions of the arrows C1 and C2, and the tips of the

rotation fulcrum portions

27a and 27b are pressed against the inner surface of the frame 1. As a result, the support member 8 is fixed to the frame 1 so as not to move.

Next, the operation of the lifting / lowering cord winding device 5 configured as described above will be described. In order to fix the lifting / lowering cord winding device 5 accommodated in the frame 1 and having the drive shaft 10 inserted through the winding shaft 9 at a desired position in the frame 1, as shown in FIG. It is assumed that it is removed from the part 35.

In this state, as shown in FIG. 7, the tips of the

rotation fulcrums

27 a and 27 b of the pressure contact member 24 are not pressed against the inner surface of the frame 1, so that the support member 8 is moved in the longitudinal direction of the frame 1 within the frame 1. It is movable.

After the support member 8 is moved to a desired position, the operation piece 32 is pushed in the direction of arrow A, and the locking portion 25 of the pressure contact member 24 is hooked on the holding portion 35 of the elastic piece 34 as shown in FIG. Then, as shown in FIG. 4, the

parallel portions

26a and 26b of the pressure contact member 24 ride on the protrusion 31 from the inclined surface 29, and the

rotation fulcrum portions

27a and 27b move in the directions of the arrows C1 and C2, and the rotation fulcrum portion 27a. 27b are pressed against the upper part of the inner surface of the frame 1 so that the lifting / lowering cord winding device 5 is fixed in the frame 1 so as not to move.

Further, when the elastic piece 34 is pushed upward, that is, in the direction of the arrow B from the state where the lifting / lowering cord winding device 5 is fixed to the frame 1, the locking portion 25 is detached from the holding portion 35. Then, the pressure contact member 24 is rotated to the state shown in FIG. 6, the pressure contact of the

rotation fulcrum portions

27 a and 27 b to the inner side surface of the frame 1 is released, and the lift cord winding device 5 is moved relative to the frame 1. It will be in a state to get.

In the lifting / lowering cord winding device 5 configured as described above, the following effects can be obtained.
(1) In a state where the locking portion 25 of the pressure contact member 24 is not engaged with the holding portion 35 of the elastic piece 34, the position of the lifting / lowering cord winding device 5 can be adjusted in the longitudinal direction of the frame 1 within the frame 1. .
(2) When the locking portion 25 of the pressure contact member 24 is engaged with the holding portion 35 of the elastic piece 34, the tips of the

rotation fulcrum portions

27a and 27b are pressed against the inner side surface of the frame 1, so The device 5 can be fixed in the frame 1.
(3) The tips of the

rotation fulcrum portions

27 a and 27 b can be pressed against the upper end portion of the inner surface of the frame 1. Since the frame 1 is opened downward, it is easy to ensure the dimensional accuracy of the interval between the upper portions of the inner side surfaces, and plastic deformation due to the press contact force hardly occurs. Therefore, the lifting / lowering cord winding device 5 can be stably fixed to the frame 1.
(4) Using the elasticity of the pressure contact member 24, the tips of the

rotation fulcrums

27a and 27b are pressed against the upper end of the inner surface of the frame 1, so that the height of the protrusion 31 can be sufficiently secured. For example, even if the dimension between the inner side surfaces of the frame 1 varies slightly, the lifting / lowering cord winding device 5 can be stably fixed.
(5) Since the press contact member 24 is formed of a metal having elasticity, the press contact force hardly deteriorates with time.

Further, in a solar shading device of a type that does not have a winding shaft, the guide roller can be fixed at an arbitrary position in the longitudinal direction of the frame 1 by the support member and the fixing means having the same configuration as in the above embodiment. It may be configured. In such a case, the support member 8 is configured to be able to support the guide roller.

(One Embodiment of the Second Aspect of the Present Invention)
An embodiment embodying a second aspect of the present invention will be described below with reference to the drawings. In the raised curtain shown in FIG. 8, the curtain fabric 2 is suspended and supported from the frame 1, and the bottom rail 4 is inserted and supported in a bag-like portion 3 formed at the lower end portion of the curtain fabric 2.

A hexagonal bar-shaped drive shaft 10 is inserted in the center of the winding shaft 9 so as not to be relatively rotatable, and one end of the drive shaft 10 is fitted to the output shaft of the operating device 11a attached to one end of the frame 1. It is worn.

A pulley 12 is rotatably supported in the operation device 11a, and an endless ball chain 13 is hooked on the pulley 12. Then, the pulley 12 is rotated by the operation of the ball chain 13.

In the operating device 11a, a torque limiter 14 and a clutch device 15a are provided. The rotation of the pulley 12 is transmitted to the drive shaft 10 via the torque limiter 14 and the clutch device 15a.

The torque limiter 14 limits the rotational torque transmitted from the pulley 12 to the clutch device 15a to a predetermined value or less, and the ball chain 13, the pulley 12, the clutch device 15a or the lifting / lowering cord winding device due to excessive rotational torque. 5 is prevented in advance.

The clutch device 15 a transmits the rotation of the pulley 12 due to the operation of the ball chain 13 to the drive shaft 10, and does not transmit the rotation of the drive shaft 10 when the curtain fabric 2 is lowered in its own weight to the pulley 12. Operate.

A stopper device 16 is disposed in the frame 1, and the drive shaft 10 is inserted through the stopper device 16. Then, after the drive shaft 10 is rotated in the pulling-up direction of the curtain fabric 2, when the ball chain 13 is released, the drive shaft 10 is prevented from rotating in the curtain fabric descending direction and the curtain fabric 2 is prevented from falling by its own weight. .

When the ball chain 13 is released by slightly rotating the drive shaft 10 in the pulling-up direction of the curtain fabric 2 from the state in which the drape of the curtain fabric 2 is prevented, the operation of the stopper device 16 is released and the curtain device 2 is released. The dough 2 is lowered by its own weight.

Next, a specific configuration of the operating device 11a will be described with reference to FIGS. As shown in FIGS. 9 and 11, the operation device 11 a has an intermediate plate 19 and a case cap 20 attached to the tip end side of the case 18. The case 18, the intermediate plate 19, and the case cap 20 are formed in line symmetry in the front-rear direction of the raised curtain.

The pulley 12 is rotatably supported on a support shaft 21 formed on the inner surface of the case cap 20, and the torque limiter 14 is disposed inside the pulley 12. When the pulley 12 is rotated by the operation of the ball chain 13, the output gear 22 of the torque limiter 14 is always rotated.

Further, the torque limiter 14 is set so as not to transmit a rotational torque exceeding a preset value to the output gear 22, and when the torque acts on the pulley 12, the pulley 12 idles with respect to the output gear 22. Yes.

The output gear 22 is meshed with a transmission gear 23 that is rotatably supported by the intermediate plate 19. Accordingly, the transmission gear 23 is rotated with the rotation of the output gear 22. The case 18 is formed with a cylindrical portion 24 projecting toward the frame 1 on the base end surface, and the clutch device 15 a is accommodated in the cylindrical portion 24. The input shaft 25 of the clutch device 15a is fitted to the central portion of the transmission gear 23 so as not to be relatively rotatable, and the end portion of the drive shaft 10 is fitted to the output shaft 26 of the clutch device 15a so as not to be relatively rotatable. Yes.

The clutch device 15 a transmits the rotation of the transmission gear 23 to the drive shaft 10 and operates so that the rotational torque applied to the drive shaft 10 from the lifting / lowering cord winding device 5 is not transmitted to the transmission gear 23.

As shown in FIGS. 11 and 12, the cylindrical portion 24 of the case 18 can be inserted into the frame 1, and the upper portion of the case 18 and the intermediate plate 19 with the cylindrical portion 24 inserted into the frame 1. When the tapping screw 30 is screwed into the rib 29 at the top of the frame 1 through the insertion holes 27 and 28 provided in the case 1, the case 18 is fixed to the frame 1.

Further, in assembling the operating device 11a, the case 18 is fixed to the frame 1 in a state in which the clutch device 15a, the intermediate plate 19, and the transmission gear 23 are accommodated in the case 18. Then, the pulley 12 and the torque limiter 14 on which the ball chain 13 is hung are attached to the case cap 20, and the case cap 20 is fixed to the case 18 with screws 35.

A flat surface 31 is formed on both sides of the outer peripheral surface of the cylindrical part 24, and

ribs

32 and 33 extending downward are formed on both sides of the lower part. When the cylindrical portion 24 is inserted into the frame 1, one of the flat surfaces 31 comes into contact with the rear inner surface of the frame 1, and the other comes into contact with the rib 34 protruding in the horizontal direction from the front inner surface of the frame 1. It has become.

The

ribs

32 and 33 sandwich a rib 35 protruding upward on both sides of the opening of the frame 1. With such a configuration, the cylindrical portion 24 can be inserted in a state of being positioned in the frame 1 in the circumferential direction.

The operation device 11a configured as described above is a right operation device attached to the right end of the frame 1. By replacing the clutch device 15a of the operation device 11a with a left operation clutch device, The operation device for the left operation can be obtained.

FIG. 10 shows the operating device 11b for left operation. The operating device 11b has the same configuration as the operating device 11a for right operation except for the clutch device 15b. In the clutch device 15b, the direction of the rotational torque transmitted to the drive shaft 10 is opposite to that of the clutch device 15a.

In addition, since the cylindrical portion 24 of the case 18 is formed in line symmetry, the case 18 and the case cap 20 are also formed in line symmetry because the case 18 and the case cap 20 can be similarly inserted into the left end of the frame 1. The operating device 15b is similar in design to the operating device 15a.

Next, the operation of the hoisting curtain configured as described above will be described. In the lifting curtain for the right operation shown in FIG. 8, for example, when the ball chain 13 hanging down indoors from the pulley 12 is pulled downward, the rotation of the pulley is transmitted to the drive shaft 10 via the clutch device 15a, and is moved up and down. The cord 6 is wound around the lifting / lowering cord winding device 5 and the curtain fabric 2 is pulled up.

When the ball cloth 13 is released after the curtain cloth 2 is pulled up to the desired height, the operation of the stopper device 16 prevents the curtain cloth 2 from falling by its own weight, and the curtain cloth 2 is held at the desired height.
