2. Description of the Related Art Conventionally, in blind shutters, as shown in FIG. 1, the slats move up and down in a horizontal state, and the angle can only be adjusted once the slats have descended to the bottom.
could not.

0003

In the past, the angle of each slat could not be tilted arbitrarily until the blind shutter was completely closed.

[0004] However, each slat in the blind shutter may be in a half-open state.

[0005] As described above, there are many requests to be able to adjust the angle of the slats so as to block sunlight etc. even when each slat is in the middle of its closing operation.

[0006]

[Means for Solving the Problems] Therefore, the present invention provides an angle adjusting body in which each slat of a blind shutter is equipped with a clutch body that corresponds to a horizontal regulating stopper and an inclination angle regulating stopper during closing of each slat. By using an angled closing device for the blind shutter that is tilted at an appropriate angle through the slats, it is possible to adjust the lighting without having to lower each slat all the way to the bottom, as in the case of conventional methods, and by stopping it halfway. This solves the above problem.

The rod portion 5a and, by extension, the slat 1 are configured to have an inclination angle.

Furthermore, when the plurality of slats 1, 1, ... are in a polymerized state, the rod parts 5a, 5a, ... of the plurality of connecting rods 5, 5, ... are in a polymerized state, as shown in FIG. It is arranged and polymerized.

A power section is mounted on the guide rail B and inside the shutter case A. As shown in FIGS. 5 and 6, the configuration of the power section is mainly composed of an angle adjustment body D and a sprocket body E, and the angle adjustment body D is connected to the angle setting link C. The slats 1, 1, . . . are connected at an angle.

Furthermore, the sprocket body E is for opening and closing each of the slats 1, 1, . . . by using a plurality of slats 1, 1, . .

The angle adjusting body D is, as shown in FIG.
It is composed of a cylindrical portion 6, an outer connecting portion 7, and an inner connecting portion 8. The cylindrical portion 6 is formed into a hollow cylindrical shape, and a clutch body 13 is housed inside the inner peripheral side surface thereof.

The outer connecting portion 7 and the inner connecting portion 8 are formed to protrude from the outer circumferential side of the cylindrical portion 6, and in a specific embodiment, a fan-shaped cam plate is formed from the outer circumferential side of the cylindrical portion 6. 9 is formed, and an outer connecting portion 7 and an inner connecting portion 8 are present within the cam plate 9. Further, the outer connecting portion 7 and the inner connecting portion 8 are formed to be shifted in plan and to be at different levels.

The sprocket body E, as shown in FIG.
It consists of a shaft part 10 and a sprocket part 11, and opens and closes each slat 1, 1, . . . via a chain 12.

The shaft portion 10 of the sprocket body E is inserted into the inner circumferential surface of the cylindrical portion 6 of the angle adjusting body D via the clutch body 13, and as shown in FIG.
3, the cylindrical portion 6 of the angle adjustment body D rotates with the rotation of the shaft portion 10 of the sprocket body E, and also as shown in FIG.
0, the shaft portion 10 and sprocket portion 11 of the sprocket body E are configured to be able to rotate even if the cylindrical portion 6 is forcibly stopped.

The clutch body 13 is of a coil spring type, and has end projections 13b, 13b formed on both sides of a coiled tightening portion 13a.

The tightening force of the tightening portion 13a is strengthened or loosened by slight movement of the end projections 13b, 13b.

The end protrusions 13b, 13b protrude outward from the cylindrical portion 6 from two slit-like notches 6a, 6a formed in the cylindrical portion 6 of the angle adjusting body D.

Further, around the angle adjusting body D, as shown in FIGS. The angle is limited within a predetermined range.

That is, as shown in FIG. 5, the end projections 13b, 13b of the clutch body 13 housed in the angle adjusting body D protrude outside from the slit-like notches 6a, 6a of the cylindrical portion 6. One of the end protrusions 13b, 13b contacts the horizontal regulating stopper 14, and the other contacts the inclination angle regulating stopper 15, as shown in FIG. Outer connecting portion 7 of adjustment body D
and limits the movable range of the inner connecting portion 8.

Furthermore, when the end projections 13b, 13b of the clutch body 13 in the cylindrical portion 6 of the angle adjustment body D come into contact with the horizontal regulation stopper 14 and the inclination angle regulation stopper 15, the clutch body 13 is tightened. The tightening force of the portion 13a will be loosened.

[0035]The rotation of the cylindrical part 6 stops, and accordingly, the outer connecting part 7 and the inner connecting part 8 also stop moving, but the shaft part 10 of the sprocket body E and the sprocket part 11 continue to rotate. , each slat 1, 1, . . . is only raised and lowered by a chain 12 wrapped around a sprocket portion 11.

The outer connecting part 7 of the angle adjusting body D is connected to the uppermost outer link piece 2a of the outer link part 2, and the inner connecting part 8 is connected to the uppermost inner link piece 3 of the inner link part 3.
Connected to a.

The connection is made by a connecting body 16, and as a specific example of the connecting body 16, as shown in FIG. 7, a metal wire or a chain is used. Sometimes.

When the cylindrical portion 6 of the angle adjustment body D rotates within a predetermined angle range, the outer connecting portion 7 and the inner connecting portion 8 move on the circumference with the rotation of the cylindrical portion 6, and accordingly, the connecting portion 7 and the inner connecting portion 8 move on the circumference. The bodies 16, 16 move up and down to move the outer link part 2 and the inner link part 3 in the up and down direction.

As the outer link portion 2 and inner link portion 3 move in the vertical direction, the angles of the connecting rods 5a, 5a, . . . of the connecting rods 5, 5, . . . fixed to the slats 1, 1, . changes, and as a result, the inclination angles of the slats 1, 1, . . . also change.

Furthermore, each slat 1 is inclined at an appropriate angle (approximately 45 degrees) when the blind shutter is closed, and the angle of inclination can be adjusted by the angle adjustment member D.

Specifically, this can be achieved by changing the distance between the two end protrusions 13b, 13b of the clutch body 13 in the angle adjusting body D.

This is because, as shown in FIG. 7(a) or FIG. 9, the slat 1 is in a horizontal state with the end protrusion 13b of the angle adjustment body D in contact with the horizontal regulation stopper 14. Furthermore, as shown in FIG. 8(a) or FIG. 10, the inclination angle of the slat 1 at the time of the closing operation is determined at the time when the end projection 13b comes into contact with the inclination angle regulating stopper 15.

That is, since the inclination angle of the slat 1 is determined by the contact of the end protrusion 13b of the angle adjustment body D with the inclination angle regulating stopper 15, the size of the inclination angle regulating stopper 15 can be changed as appropriate. Therefore, the inclination angle of the slat 1 can be set arbitrarily.

Furthermore, the two end projections 1 of the angle adjustment body D
The inclination angle of the slat 1 can also be changed by appropriately changing the distance between the slats 3b and 13b.

Furthermore, as shown in FIG. 8(b), cam pieces 12a are fixed to appropriate locations on the chain 12, and the cam pieces 12a are configured to pass through 15 inclination angle regulating stoppers. The inclination angle regulating stopper 15 is moved when the cam piece 12a passes through the 15 inclination angle regulating stoppers.

The inclination angle regulating stopper 15 allows the cylindrical portion 6 of the angle adjusting body D to rotate only within a predetermined angle range, but when the inclination angle regulating stopper 15 is moved by the cam piece 12a, the cylindrical portion 6 rotates. The rotation of the slats 1, 1, . . . can be made vertical.
