Abstract: A safe curtain control assembly which does not require screws to assemble is revealed. The safe curtain control assembly includes a stopping portion located on a wall of a cavity of a base forming a raised structure, and a recessed area is formed by the wall of the cavity and the stopping portion. A sleeve, an elastic member and a drive member are mounted within the cavity of the base in turn. A second stopping flange of the drive member is positioned in the recessed area between the wall of the cavity and the stopping portion for preventing the sleeve, the elastic member, and the drive member assembled from being released. Thereby the base, the sleeve, the elastic member and the drive member are secured firmly without screws so as to save time and cost for each assembly.

Abstract: A fast positioning structure of a safe position limiting device of a roller blind is disclosed herein. It mainly comprises a controller having an axle rod, an axial rail limiting assembly assembled to the axle rod and having a screw member, an elastic member in the screw member, and an inner tube with which a first tooth part is provided, a touch member for limiting the inner tube in the screw member, a positioning member and a position limiting member disposed at an external of the screw member, and an outer sleeve tube disposed at an external of the screw member and having a seal cap with which a second tooth part is provided at one end thereof for corresponding to the first tooth part of the inner tube.

Abstract: A screwless curtain control assembly is revealed. An assembly segment is disposed on one end of a bead chain base while first radial positioning parts and first axial positioning parts are arranged at the assembly segment alternately. A sleeve including second radial positioning parts and second axial positioning parts is mounted to the assembly segment of the bead chain base. Thereby the bead chain base and the sleeve are connected stably by the first radial positioning parts and the first axial positioning parts connected to and positioned by the second radial positioning parts and second axial positioning parts respectively. Thus both labor time for fastening screws and cost of the screws are saved. Therefore the screwless curtain control assembly meets the modern industry's requirement for high efficiency at low cost.

Abstract: A curtain reel structure for rapidly positioning and locking is disclosed herein. It mainly comprises a winding spool, a reel seat for an assembly of the winding spool and having a neck part, a removable lock element pivotally connected to the neck part of the reel seat, and a flexible member engaged with the neck part of the reel seat. The removable lock element pivots to change direction and contacts the flexible member to lift and lower the flexible member.

Abstract: A curtain reel structure for assembling a blind cord rapidly is disclosed herein. It mainly comprises a winding spool, a reel seat on which the winding spool is assembled, a first positioning device disposed between the winding spool and the reel seat and having a first chamber and a first sliding seat inserted into the first chamber, wherein the first sliding seat is provided with a first accommodating slot for accommodating the blind cord, and a second positioning device disposed between the winding spool and the reel seat and having a second chamber and a second sliding seat inserted into the second chamber, wherein the second sliding seat is provided with a second accommodating slot for accommodating the blind cord.

Abstract: A safety device for a curtain controller is provided. The safety device comprises a base, a bead chain wheel, and a cover. A shaft sleeve having a conical shape is disposed in a through hole of the base to connect a shaft's terminal and thus be fixed in a sleeving hole, having a shape to fit the shaft sleeve, of the bead chain wheel, so that the motions of the shaft sleeve and the bead chain wheel are linked. A bead chain is wound on the bead chain wheel. When the bead chain is pulled down, the shaft sleeve can drive the rotation of the bead chain wheel. The upper part of the cover is pivotally connected to the base, and the lower part of the cover buckles the base. Therefore, when the bead chain is instantly pulled down, the cover can be opened to drop the bead chain wheel.

Abstract: The invention relates to a curtain security structure driven by a bead chain, comprising an upper assembler, a lower assembler, and flexible support parts to be assembled correspondingly. A lower rotary wheel of the lower assembler is engaged with an upper rotary wheel of the upper assembler. The two flexible support parts are inserted from the bottom of the lower assembler to assemble the upper and the lower assemblers. An upper bead chain and a lower bead chain are entwined and disposed in upper and lower bead pockets respectively via pockets disposed on struts of the flexible support parts. When children improperly use the curtain security structure and thus are entwined by the lower bead chain and struggle, the lower bead chain, the lower assembler and the flexible support part can simultaneously detach from the upper assembler to prevent the children from being damaged to achieve the safe protection effect.

Abstract: A safety assembly structure of a curtain bead chain is revealed herein. It comprises a bead chain having a string with a plurality of beads and having a safety assembly thereon for controlling a curtain. The safety assembly includes two insert blocks for joining to both ends of the string of the bead chain and a connecting unit wrapping around the two insert blocks for connecting thereof.
