A connector for coupling to a bead chain is disclosed. In use, the connector is arranged and configured so that the connector can pass over a bearing. In one example of an embodiment, the bearing is positioned in a tensioner so that the connector moves through the tensioner, which is operatively coupled to the bead chain. In one example embodiment, application of a force on the bead chain to move the covering between an extended position and a retracted position, self-orients the connector so that a top portion of the connector faces and/or contacts the bearing so that the connector smoothly passes across an exterior arcuate surface of the bearing. In one example embodiment, the top portion includes a curved surface to contact the curved surface of the bearing.

A method for manufacturing an operation device for shutters includes a step of forming a ladder a step of forming a receiving element, a cord accommodated in the receiving element, and a step of connecting multiple connecting elements to the ladder and the receiving element. The operation device for shutters includes a ladder, a receiving element accommodating a cord therein, and the connecting elements connected to the ladder and the receiving element.

A blind having a blind operating mechanism and an endless loop blind control element for operating the blind mechanism, comprising: an enclosure extending from an upper end to a lower end, with the endless loop blind control element enclosed within the enclosure between the upper end to the lower end of said enclosure, when in a first position; a connector supporting the upper end of the enclosure adjacent to the blind operating mechanism and depending downwardly from it; and the lower end of said enclosure moveable from said first position towards that upper end to a second position so as to permit operation of said endless loop blind control element. The invention also relates to a lower housing displaceable towards the enclosure.

The invention to which this application relates is apparatus and a method for use with blinds and louvres, hereinafter referred to, in a non-limiting manner, as blinds and which includes roller blinds, roman blinds and Venetian blinds. The apparatus and method allows the free end of the blind to be selectively positioned and retained at a predetermined position intermediate the fully retracted and fully extended positions and to be retained at that position.

An adjustment device for a drawstring of a curtain with a curtain body includes a base fixed to a bottom end of the curtain body and defining a shaft hole, a reel received and rotatably mounted in the shaft hole of the base, and a locking assembly for limiting an axial displacement of the reel. A sidewall bounding the shaft hole of the base defines a through slot. The base forms a number of first positioning portions distributed in a circle about a central axis of the shaft hole. An end of the drawstring passes through the through slot of the sidewall bounding the shaft hole and is wound on the reel. The reel forms a number of second positioning portions cooperating with the first positioning portions to prevent the reel from rotating.

A tensioner for use with an architectural-structure covering including an operating element (e.g., a cord, a chain, or the like) is disclosed. The tensioner selectively securing a position of the operating element relative to the tensioner. In one embodiment, the tensioner includes a body, a slider, a bearing, and an optional biasing member. The body may include a first body member coupled to a second body member. The slider is movably positioned within the body between first and second positions to selectively enable movement of the operating element relative to the tensioner. The bearing includes a projection for coupling to the second body member to prevent the second body member from being decoupled from the first body member. In this manner, when the bearing is enclosed within the body, a user cannot readily open the body (e.g., a user cannot readily separate the first and second body members).

A window blind includes a housing, a slat assembly, a slat angle adjusting device, and a first cord. The slat assembly is provided below the housing, and has multiple slats and a bottom end portion. The slat angle adjusting device includes a rotating shaft assembly provided in the housing, and a ladder assembly which includes at least two ladders connected to the rotating shaft assembly for turning the slats. The first cord passes on a front or a rear side of the slats, and connects the rotating shaft assembly and the bottom end portion. Throughout the duration of the rotation of the rotating shaft assembly, the first cord and a warp, which belongs to the ladder assembly and on the same side as the first cord, are both reeled into or out of the housing concurrently, and the slats and the bottom end portion are all rotated concurrently as well.
