A holder for a seamless control cord of a curtain for quickly fixing the seamless control cord or a bead chain is composed of a base seat, an outer cover and elastic members and fixed on a wall face by fixing members. The base seat and the outer cover are respectively formed with two perforations. Each perforation has a cord passage formed on the same axis. When holding the control cord, the seamless control cord is directly passed through the cord passage of the outer cover into the perforation and then passed through the cord passage of the base seat into the perforation. Then, the elastic members push the outer cover to misalign the two perforations so as to hold the control cord and fully fix the control cord. Under such circumstance, the control cord is prevented from swinging or a child cannot play the control cord.

A manually operated override release mechanism for use with a motorized window shade assembly having a shade fabric with a leading edge, the shade fabric being disposed behind a pane and movable between an opened position and a closed position upon operation of a motor. The override release mechanism has an actuator movable between a first position and a second position and biased in the first position. The actuator has a first side secured to one end of a cable, and a second side. The other end of the cable is connected to the motor.

The present invention relates to an alarm for detecting and alerting a person of an event where a device is pulled on for an extended period of time. Specifically, the present invention relates to an alarm implemented on a pull-string. Even more specifically, the present invention relates to an apparatus, system, and method of using the same that alerts a person when something becomes tangled or is otherwise caught up in the pull-string of window blinds, shades, or other light blocking devices.

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.

A safety bead chain for blinds is revealed. An external member and a mounting member are disposed on two ends of the bead chain respectively. The external member consists of a groove and at least two first locking parts arranged around the groove. The mounting member is set with at least two second locking parts locked with the first locking parts correspondingly. Thus the external member and the mounting member are locked with each other to form a safety bead fastener bead with the same shape as a bead of the bead chain. The two ends of the bead chain are released from each other once a pulling force is applied to the bead chain to keep children from getting tangled in the bead chain. Moreover, the bead chain is moved around the clutch in a circular manner. Users can operate the bead chain more conveniently.

An actuating device (10) actuates a shading system with a string element (44). An unintended detachment of a first partial structure (12) from a second partial structure (13) in the intended use is avoided as much as possible and a detachment of the first partial structure (12) from the second partial structure (13) is possible with low forces for avoiding injuries. The actuating device (10) includes a first coupling element (26, 27) that in the released position does not mesh with a second coupling element (28, 29), and in the locking position, with an interaction of the first coupling element (26, 27) with the second coupling element (28, 29), a detachment of the first partial structure (12) from the second partial structure (13) is prevented because of a positive-locking connection between the first coupling element (26, 27) and the second coupling element (28, 29).
