BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel blind having a curtain function and a horizontal blind function.

[0002]

2. Description of the Related Art Hitherto, for example, lace curtains have been suitably used as windows having the characteristics of not allowing the interior to be seen from the outside and the exterior to be seen from the interior of the room, and having a characteristic of taking in soft light. I have. However, lace curtains are insufficiently shaded when the sunlight is strong,
It has the disadvantage that the room can be seen from the outside at night.

In order to solve this drawback, for example, a number of horizontal slats are arranged vertically at predetermined intervals, and a horizontal blind for adjusting the lighting by changing the inclination of the slats by a ladder code is used as a curtain for a race. It is common that it is attached.

[0004]

However, if a curtain and a blind are provided side by side, the curtain and the blind must be operated separately, which is troublesome and inconvenient. Further, there is a problem that a space for mounting both the curtain and the blind is required, and that the mounting must be performed separately, which is troublesome.

[0005] An object of the present invention is to provide a novel blind which solves such a conventional problem.

[0006]

In order to solve the above-mentioned problems, the present invention integrates a curtain and a blind. That is, in the blind of the present invention, the screen is hung down from the take-up cylinder supported at both ends, and the screen is made to be able to move up and down by rotation of the take-up cylinder. A large number of tilting slats are arranged side by side at predetermined intervals vertically along the curtain raw cloth between the curtain raw cloths, and each of the slats is supported by a supporting member attached to the curtain raw cloth. The winding drum is divided into a drum main body that rotates integrally with its central rotation axis, and an auxiliary body that can be joined to the drum main body, and the upper end of one of the opposing curtain fabrics is attached to the drum main body, and the other is attached to the drum main body. The upper end of the curtain cloth is attached to the trunk body via the auxiliary body, the auxiliary body is supported away from the trunk main body when the screen is lowered most, and when the screen is raised from the lowest position, the trunk main body is supported. Auxiliary member after a predetermined angular rotation is joined pulled the curtain raw cloth to the barrel main body is obtained by such wind the screen winding Todo.

[0007]

[0008]

[Function] While the soft atmosphere of the curtain is maintained by the opposing curtain fabric, the shading is adjusted by tilting the slat. Moreover, the curtain fabric and the slats are raised and lowered simultaneously by raising and lowering the screen.

Further, since the winding cylinder is divided into a main body and an auxiliary body and the screen is wound on the winding cylinder, a slat having a convexly curved upper surface is wound along the winding cylinder, and the screen is screened. Can be easily wound without bulkiness.
