Abstract: An extensible curtain rail includes a rail main body, more than one connection seat and a decorative panel. The decorative panel and the rail main body are assembled and connected with each other by means of the connection seat. The connection seat can be inward contracted or outward extended to adjust the gap between the decorative panel and the rail main body in accordance with different sizes of curtain assemblies to facilitate installation thereof. The decorative panel is detachable from the rail main body to provide larger installation space and more quickly install the curtain assembly.

Abstract: A rainbow blind structure includes a drive shaft, two sleeves, two side caps, a lower weight and a locating plate. The drive shaft is connected with the side caps via the sleeves and rollable. The side caps are connected with the lower weight by means of screws. The rainbow blind sheet is wound over the drive shaft. When a blind sheet winder is operated to wind or unwind the blind sheet, the drive shaft is driven to move up and down, whereby the lower weight is moved up and down with the drive shaft. The weight of the lower weight can keep the blind sheet plane and tidy. The lower weight is formed with a locating slot. When a blind sheet is affixed to the lower weight to enclose the same, the locating plate is inserted in the locating slot to locate the blind sheet around the lower weight.

Abstract: A roller curtain structure includes a cord winder seat, two curtain sheets, several sunshade fabrics and two lower weights. The two curtain sheets are connected with two sides of the reel and naturally suspended therefrom at equal height. The lower weights are connected to bottom ends of the two curtain sheets to apply downward pull force to the curtain sheet so as to provide a smooth sunshade face. When it is desired to shade the sunlight, the reel is rotated to wind one of the curtain sheets to lift one of the two lower weights and make the two curtain sheets get closer to each other. Accordingly, the sunshade angle of the sunshade fabrics connected between the curtain sheets is synchronously adjusted to partially or fully shade the sunlight.

Abstract: A roller curtain fixing bracket for both inner and outer windows, which is composed of two identical components for more conveniently installing the entire roller curtain assembly on the wall faces of the inner and outer windows. The roller curtain fixing bracket includes a base seat, two connection boards integrally extending from two ends of the base seat in reverse directions, and two support boards connected with the connection boards to form a main structure of the fixing bracket. After the main structures of the fixing brackets are locked on the left and right corners of the window, one single roller curtain assembly or double roller curtain assemblies can be installed on the support boards to provide sunlight shading effect.

Abstract: A curtain cord winder structure includes a cord winder base seat, a shaft, a cord reel, a movable cover board and a movable bracket. The curtain cord winder structure is characterized in that the cord reel includes an outer drum-shaped structure composed of multiple arched recessed wall faces and multiple arched raised wall faces that are connected with each other and an inner reinforcement structure formed on inner circumference of the cord reel. When the pull cord is wound around the outer drum-shaped structure of the cord reel, the pull cord is securely supported and located to save strength in operation of the pull cord. The inner reinforcement structure serves to reinforce the outer drum-shaped structure to avoid deformation of the cord reel.

Abstract: A pull cord fixing support for inner and outer windows includes a main support body, a movable support, a roller and a fixing toothed section, which are assembled with each other. The pull cord fixing support serves to fix a bead pull cord on a wall. The bead pull cord is first connected and engaged with the roller mounted on the movable support by means of the fixing toothed section. Then a fixing screw is used to affix the main support body on the wall. At the same time, the fixing toothed section is pulled downward to disengage the fixing toothed section from the roller. Under such circumstance, the bead pull cord can be operated. The roller is freely rotatable along with the movable support. Therefore, the pull cord can be universally operated. The pull cord fixing support is applicable to both inner window and outer window.

Abstract: A roller curtain fixing bracket assembly includes a left support, a right support, a decoration board and two cover boards covering the left and right supports. A roller curtain device can be installed between the main bodies of the left and right supports. Each of the left and right supports has a plane board main body and several fixing boards protruding from outer edges of the plane board main body. Front edge of each of two fixing boards extending from two sides of the plane board main body is formed with a split. The decoration board has a horizontal panel and a vertical panel. A top end and a certain section of the vertical panel are formed with hook bars inserted and latched in the splits of the left and right supports and assembled therewith. The cover boards serve to conceal the seams between the supports and the decoration board.

Abstract: A support structure for increasing fixing force of a curtain. The support structure includes an insert body including a main body with a central hollow structure and a metal pin body. The metal pin body can be plugged into the hollow structure of the main body. The metal pin body has a protruding cylindrical rod section. The insert body is received in a central socket of the curtain control seat. The curtain control seat has two protruding engagement bodies disposed on two sides of the central socket. The protruding cylindrical rod section of the metal pin body is inserted into the through hole of the fixing bracket and the engagement bodies are correspondingly fixedly engaged with rectangular perforations of the fixing bracket. Accordingly, the fixing force of the curtain is increased and the stability of the curtain sheet is enhanced.

Abstract: A double-roller curtain mount structure includes a fixing bracket, a support rod and two fixing members. The support rod is fitted through and connected with the fixing bracket. The two fixing members are locked on the support rod to fix the support rod on the fixing bracket. The support rod has an internal space. Two roller curtain assemblies can be inserted into the internal space of the support rod from two sides of the fixing bracket to get closer to the fixing bracket so as to shorten the light gaps between the two roller curtains and the fixing bracket and enhance the sunlight shading effect of the roller curtains.

Abstract: A roller curtain fixing bracket assembly includes a left support, a right support, a decoration board and two cover boards covering the left and right supports. A roller curtain device can be installed between the main bodies of the left and right supports. Each of the left and right supports has a plate board main body and several fixing boards protruding from outer edges of the plane board main body. Front edge of each of two fixing boards extending from two sides of the plane board main body is formed with a split. The decoration board has a horizontal panel and a vertical panel. A top end and a certain section of the vertical panel are formed with hook bars inserted and latched in the splits of the left and right supports and assembled therewith. The cover boards serve to conceal the seams between the supports and the decoration board.
