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).

A window blind includes a headrail, a bottom rail, a plurality of slats, and a cord. The slats are arranged between the headrail and the bottom rail, and each slat has two bores and one or plural of locking slots. Each locking slot has an open end and a closed end, and the opening end of the locking slot is connected to the bore. The cord passes through the headrail and the bores of the slats, and being fastened to the bottom rail. A diameter of the cord is greater than or equal to a width of the locking slot. As a result, the cord goes into the locking slot quickly and can be clamped by edges of the locking slot while a kid is trying to pull the cord out of the slats.

The present invention is a tensioner for securing a loop of roller blind chain to a window frame and to a wall adjacent the window frame. The tensioner includes a member having a top portion with a peripheral edge, a bottom portion, opposite end portions, opposite side portions, and a central aperture passing through the opposite side portions and positioned between the opposite end portions and between the top and bottom portions. The central aperture is dimensioned to permit the roller blind chain to pass there through. The member has a first thickness separating the opposite first and second sides of the member and a second thickness between the central aperture and the peripheral edge, the first thickness and the second thickness each being greater than the distance separating the beads of the chain. The member is configured such that the member is mountable in both a vertical orientation on the window frame wherein the opposite side portions are oriented in horizontal alignment and the end portions are oriented in vertical alignment and a horizontal orientation wherein the opposite side portions are oriented in vertical alignment and the end portions are oriented in horizontal alignment. Finally, the top portion of the member is curved such that the loop of roller chain is positioned perpendicular to the wall when the member is mounted in its horizontal orientation.

A locking member to be used in conjunction with a guide ring and a lift cord configured to raise of lower a covering for an architectural opening, such as a window, door or the like, is disclosed. The locking member is configured to engage the guide ring and the lift cord in such a way that the locking member has a selective rotative ability, which allows the lift cord to freely move in a first direction to raise or lower the covering, but the locking member will move or rotate about the guide ring when the lift cord is pulled in a second direction to pinch the lift cord between the locking member and the guide ring so that the lift cord is prevented from being pulled away from the covering far enough to create a loop of a certain diameter.

A cord safety device for a window covering includes a first and a second body. The first body includes: a first pivot portion, disposed on a periphery; a first fixing portion, disposed on a periphery at a predetermined angle with respect to the first pivot portion; a first stop portion, disposed on an inner side of the first body and protruded towards the second body; a first recess, disposed on an upper periphery; and a guiding block, disposed on one end of the first stop portion adjacent to the first fixing portion, in which the guiding block has a guiding surface for guiding the cords. The second body includes: a second pivot portion, disposed corresponding to the first pivot portion; and a second fixing portion, disposed corresponding to the first fixing portion, thereby being separably fixed with the first fixing portion.

A cord winding device for a window covering includes a casing, a reel rotatably mounted on the casing, a torsion spring biased between the casing and the reel, a limit ring secured on the casing and abutting the reel to limit the reel between the casing and the limit ring, and a pull cord attached a bottom of the casing. Thus, the lift cord of the window covering is wound around and stored in the reel of the cord winding device so that the lift cord is rolled up to a higher position to prevent the children from being tangled with the lift cord so as to protect the safety of the children.
