Abstract: A slide rail structure for a window blind includes at least one extensible rail set, at least one pulley set, and a plurality of top brackets. The extensible rail set is provided with at least two slide rails which are loosely extended with respect to each other and are assembled together, and a side of each slide rail is provided with an open slot. The pulley set is loosely assembled in the slide rail of extensible rail set, and is extended out of the open slot at one side of each slide rail. A side of each top bracket is formed with an arc-shape locking part for sheathing the slide rail of extensible rail set, and a top of each top bracket is provided with a hole for locking and positioning. The slide rail structure can be easily and quickly assembled, can be rigidly positioned and can slide smoothly.

Abstract: Composite curtains embodying a plurality of rows of pleats located on upper portions of curtain units of curtains include that corresponding fastening members stitched to a front side and reverse side of two side edges of each of the curtain units. A draw pleat tape is located on a reverse side of an upper cover valance of an upper portion of the curtains, and a variable lower hem is located on a lower side of each of the curtain units. Two curtain units or more than two curtain units can be joined together to form curtains of an appropriate width by means of the fastening members. Furthermore, the draw pleat tape can be used to adjust width of the upper cover valance, and the variable lower hem can be used to adjust length of the curtain units, thereby enabling the curtains to match actual width of a variety of windows.

Abstract: Composite curtains comprising a plurality of rows of pleats configured on top portions of each curtain, moreover, a plurality of curtain hooks is configured on top portions of the pleats. The present invention is characterized in that corresponding fastening members are sewn on a front side and a reverse side of two side edges of each of the curtains respectively, thus enabling the curtains to be joined together to form an appropriate width by means of the fastening members, and thereby suitably shading split widths of a window.

Abstract: A side wheel assembly of curtain track as a flexible assembly, includes a frame, a fastening member, a sealing member and related elements, which are all formed from plastic materials. The invention has a compact structure, and the elements thereof are assembled and located using simple fastening procedures, thereby accomplishing quick assembly purposes.

Abstract: A rolled tube fabrication method of making a rolled tube by: cutting a surface-treated metal sheet material subject to the desired size, and then bending the two opposite lateral side edges of the surface-treated metal sheet material into a respective hooked portion, and then forcing the two hooked portions of the surface-treated metal sheet material to hook each other, and then roller-ramming the hooked area of the surface-treated metal sheet material so as to obtain a finished rolled tube.
