Multiple first magnets are connected to the lower portion of the inside of each curtain piece, and multiple second magnets are connected to the top portion of the outside of each curtain piece. The second curtain unit is connected to the third curtain unit, and third curtain unit is connected to the first curtain unit. The multiple curtain pieces are able to be individually folded to introduce outside light into the room via the folded curtain pieces.

Abstract: A Roman shade includes a translucent layer and at least one opaque layer. The translucent layer is connected to the top box. Multiple rows of first magnets are positioned transversely on the translucent layer. A translucent area is formed between any two adjacent rows of the first magnets. The opaque layer includes multiple rows of second magnets positioned transversely thereon, and an opaque area is formed between two any adjacent rows of the second magnets. The at least one opaque layer is folded to attract the second magnets on the at least one opaque layer to the first magnets on the translucent layer to expose the translucent areas.

Abstract: A cordless curtain assembly includes a fabric connected to a top rail. The fabric has multiple transverse folding sections and each folding section has a passage defined therein. Multiple magnetic units are respectively received in the passages of the folding sections and each have a carrier, multiple clamping members and multiple magnetic parts. The carrier of each magnetic unit has two reception areas defined in the top thereof. Each clamping member has a press bar and two legs which respectively extend from the underside of the press bar.
