  • Publication number: 20140174678
    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.

  • Publication number: 20130264018
    Abstract: A roller curtain controller includes a cap, a collar, a locating block, a pull cord reel and an outer sleeve. The cap is recessed to forma receiving space. The cap has a restriction stem protruding from a bottom wall of the receiving space. The collar is fitted on a fixed end of the restriction stem and the locating block is fitted on a front end of the restriction stem. The pull cord reel is fitted on the collar and spaced from the bottom wall of the receiving space by the collar to form a gap so as to reduce frictional noise. The locating block is assembled with the outer sleeve. By means of the support of the locating block, a central axis of the restricting stem is prevented from being deflected under the weight of the roller curtain so that the roller curtain can be operated more smoothly.

  • Publication number: 20130247336
    Abstract: A roller shutter bead chain connector includes a connector main body having an internal receiving space for receiving beads of the bead chain. Two engagement slots are formed at two ends of the connector main body. A string segment between two beads is engaged into the engagement slot to connect the connector main body with the bead chain for controlling the up and down movement of the roller shutter. The connection main body can be fitted on any section of the bead chain as necessary, whereby the connection main body can be stopped to locate the roller shutter curtain at a desired height.

  • Publication number: 20130067835
    Abstract: A decorative frame body includes at least four decorative boards and several fixing seats. Each decorative board has a sunshade section and an engagement channel formed on the bottom face of the decorative board. Each fixing seat has a fixing base and latch sections extending from the fixing base in adaptation to the engagement channel. The fixing seats are fixed on the wall face beside the window frame. The latch sections of the fixing seats are latched in the engagement channel to connect the decorative boards with the fixing seats as a decorative periphery of the window. The sunshade sections of the decorative boards serve to block the gaps between the blind slats and the window frame and prevent the sunlight from going into the room from the gap.

  • Patent number: 8365362
    Abstract: A safety release device for Roman blind pull cord is disposed between the control pull cord of the Roman blind and a lower suspension thereof. The safety release device includes a latch body for connecting with the pull cord, a latch ring seat connected with the lower suspension of the Roman blind, and a connection barrel. The latch body can be plugged into and latched with the connection barrel or extracted out of the connection barrel. The latch body has a latch force greater than the weight of the suspended Roman blind. When an abnormal pulling force greater than the latch force between the latch body and the connection barrel is applied to the pull cord in any direction, the latch body will be easily extracted out of the connection barrel to avoid tangle of the pull cord with a kid and ensure safety in use of the Roman blind.

  • Publication number: 20120227913
    Abstract: A polygonal drum for controlling blind slats is pivotally connected with a control bar in a blind tilt mechanism for adjusting the angle of the blind slats or controlling opening/closing the blind slats. The polygonal drum includes an elongated equilateral polygonal drum body having multiple plane sidewalls with equal area. The plane sidewalls form the periphery of the elongated equilateral polygonal drum body for winding/unwinding a ladder string by equal length. Accordingly, the blind slats can be easily stably operated and adjusted without obstacle. The polygonal drum further includes multiple reinforcement ribs perpendicularly extending from inner faces of the plane sidewalls to integrally connect with a control bar passage. The reinforcement ribs serve to increase the strength of the polygonal drum so as to overcome the problem of deformation of the conventional control drum.

  • Patent number: 8201789
    Abstract: A blind support for installation of a blind rail. The blind support includes a main support body and an engagement member. The main support body has two horizontal support boards and a vertical support board connected between the horizontal support boards to form a support body with an open side. The blind rail can be placed into the main support body through the open side thereof and supported by the main support body. The engagement member has horizontally extending abutment sections that can be slidably received slide channels of the main support body. Each abutment section has a key body projecting therefrom. The key bodies are engageable in engagement holes formed on the main support body to block the open side thereof and enclose and support the blind rail.

  • Publication number: 20120091246
    Abstract: A cord winder seat structure installed in a shutter rail for controlling opening/closing of the slats of the shutter. The cord winder seat structure includes a cord reel having a polygonal drum body. The polygonal drum body is composed of several plane sidewalls connected with each other. The polygonal drum body has several angles contained between the plane sidewalls. A pull cord is wound around the polygonal drum body for rotating the cord reel. The angles of the polygonal drum body serve as pull points for the pull cord. When a user pulls the pull cord to rotate the cord reel, the pull cord can apply a pull force to the angles to more precisely operate and locate the cord reel and save strength. An oblique slot is formed on a plane sidewall of the drum body on an inner side thereof to avoid tangling of the pull cord.
