The at least one attracting member and the at least one attracted member are magnetically attracted with each other.

Abstract: A shade includes a main unit and a plurality of magnetic members. The main unit includes a shade cloth member and a plurality of transverse bars. The shade cloth member is provided with a first tubular portion and a second tubular portion and divided into a first shading portion and a second shading portion. The second shading portion is divided into a plurality of movable shading pieces each provided with a plurality of transverse mounting sleeves. The transverse bars are mounted in the second tubular portion and the mounting sleeves. The magnetic members are mounted in the transverse bars. Thus, the second shading portion can regulate the incident sunlight passing through the shade cloth member by expanding, partially folding or fully folding each of the movable shading pieces to adjust the shading effect of the shade cloth member.

Abstract: A curtain bead chain fixing device includes a bead chain guide way through which a bead chain as a pull cord for controlling a curtain is extended and thereby becomes connected to the fixing device, and an elastically movable interfering element being normally pushed into the bead chain guide way to interfere with the free movement of the bead chain in and along the bead chain guide way. When the fixing device is adequately mounted to a wall surface according to specified installation procedures, the interfering element is forced out of the bead chain guide way to release the bead chain therefrom. Therefore, a user of the curtain is urged and guided to adequately mount the fixing device to hold the bead chain in place, and undesired accidents caused by a swinging bead chain can be avoided.

Abstract: A curtain rail structure includes a first rail unit having two adjacent first sliding rails, each of which defining on one side a first sliding channel; a second rail unit movably connected with the first rail unit and including two second sliding rails separately and movably received in the first sliding rails and respectively defining on one side a second sliding channel corresponding to and communicating with one of the first sliding channels; and a plurality of hanging units separately and movably connected to the first and the second sliding rails and respectively including sliding members movably mounted to the first and the second sliding channels, and a hanger member connected to the sliding members. The second sliding rails can be extended from or retracted into the first sliding rails, allowing the curtain rail structure to be practically and conveniently used with differently sized windows and be easily mounted.

Abstract: In a retarding structure for rolling a curtain and a manufacturing method thereof, the retarding structure includes a housing, a shaft and an elastic element. The shaft is movably coupled into the housing, an end of the shaft is extended out from the housing; and an elastic element is sheathed onto the shaft, and both ends of the elastic element are abutted against internal walls of the housing respectively. The housing can be combined with any curtain rod having an automatic rolling mechanism, such that when a curtain fabric rolled up to the curtain rod by the automatic rolling mechanism, the shaft together with the elastic element are used to gradually increase the resistance produced during the rolling, so as to prevent the curtain fabric from rolling up instantly, and achieve the effects of preventing the curtain from being damaged easily and providing a universal application.

Abstract: A safety support for a curtain comprises a supporting base having a receiving unit set at one side of the supporting base, and a supporting plate coupling to one side of the supporting base, wherein the supporting plate comprises a connecting unit which is coupled to the receiving unit of the supporting base, and an aperture. The safety support is constructed in such that when the external force exerted on the safety support of the curtain exceeds a pre-determined safety weight setting, the connecting unit of the supporting plate will disconnect immediately from the receiving unit of the supporting base so that the curtain will be detached from the supporting plate of the safety support so that the child is protected from suspension from the curtain.

Abstract: A mounting aid for installing curtain rod brackets includes a main body is at two opposite ends with correspondingly arranged marking holes. With the mounting aid, a user can easily utilize the marking holes to put marks on a wall at desired positions for fixing curtain rod brackets, allowing quick execution of subsequent steps of fixing brackets and assembling the curtain rod to complete the installation of a curtain at reduced labor and time cost.

Abstract: A safety mechanism for Roman shade includes a shade assembly having a head rail, a shade cloth connected to the head rail, and connecting members set on the shade cloth; a lifting unit connected to the shade assembly and having pull cords and raising cords connected thereto; a plurality of butt-connecting devices connected to the pull cords and each having two detachably connected upper and lower sleeves; and a plurality of locking members associated with the raising cords and detachably engaged with the connecting members. When a pull cord or a raising cord is subjected to a load excessively larger than a force needed to lift or lower the shade cloth, the upper and lower sleeves of the butt-connecting device on that pull cord will separate from each other and the locking members on that raising cord will disengage from the connecting members, making the Roman shade safer for use.

Abstract: A safety device for roller shade bead chain includes a connecting seat, a rotary disc disposed atop the connecting seat and provided along a circumferential face with a plurality of retaining recesses, an elastic element located between the connecting seat and the rotary disc, and a cover plate assembled to the connecting seat to restrict the rotary disc and the elastic element to the connecting seat. A bead chain for controlling a roller shade can be wound around the rotary disc, and then pulled into a straight state before the connecting seat is fixed to a predetermined position. The bead chain being pulled straight and held in place via the safety device will not swing freely to dangerously entangle with and strangulate a child, and is therefore safer for use.

Abstract: A curtain bead chain fixing device includes a bead chain guide way through which a bead chain as a pull cord for controlling a curtain is extended and thereby becomes connected to the fixing device, and an elastically movable interfering element being normally pushed into the bead chain guide way to interfere with the free movement of the bead chain in and along the bead chain guide way. When the fixing device is adequately mounted to a wall surface according to specified installation procedures, the interfering element is forced out of the bead chain guide way to release the bead chain therefrom. Therefore, a user of the curtain is urged and guided to adequately mount the fixing device to hold the bead chain in place, and undesired accidents caused by a swinging bead chain can be avoided.
