Abstract: The invention refers to a pull cord arrangement for a roller blind or a venetian blind, comprising a winding element (4) arranged to be connected to a blind (6) such that the blind (6) is released or wound in response to a rotational movement of the winding element (4) about a rotational axis; a connecting element (28) coupled to the winding element (4) to rotate together with the winding element (4); and a pull cord (50) engaging the connecting element (28) so as to control the rotation of the connecting element (28) and thus the winding element (4) as the pull cord (50) is operated.

Abstract: In one aspect, a slat configured for use with a covering for an architectural structure includes a route slot defined at least partially by a route wall that is recessed relative to one or more outer faces of the slat. Additionally, the recessed route wall further defines a through-hole for passing a cord through the route slot between the opposed outer faces of the slat. By configuring the disclosed route slot in this manner, the dimensions of the through-hole can be significantly reduced while still allowing full tilting of the slat to the closed position, thereby increasing light control and privacy for the associated covering.

Abstract: A hand-held curtain is provided. The curtain includes a left bracket, a right bracket corresponding to the left bracket, and a pylon connected to the left bracket and the right bracket. A scroll is arranged on the left bracket and the right bracket; a roller blind is arranged on the scroll; and coiling apparatuses used for coiling the scroll are respectively arranged on the left bracket and the right bracket.

Abstract: The present invention provides a cordless blind apparatus that can be conveniently operated without a cord. The cordless blind apparatus includes: a roller that is fitted on a rotary shaft; a screen that is wound or unwound on the roller; a weight that is connected to the lower end of the screen and applies torque in a first direction in which the screen is unwound from the roller by the gravity; an elastic member that applies torque in a second direction in which the screen is wound, by applying elastic force to the roller; and a friction stopper assembly that generates friction force on the roller.

Abstract: A box for a system for opening and closing a communication route between two separate areas, the system including separation means suitable for allowing and preventing, respectively, at least partially, crossing of the route by light, may include: a box body configured to accommodate a movement unit of the system; and support elements for the movement unit. The box body may have a major extension direction. The box body may be defined by support and closing profiles, both extending along the direction. The support profile may define at least one upper, lower, and connecting wall. The closing profile may define a closing wall. The closing profile may be removably fixable to the support profile for closing the box body. When the closing profile is fixed to the support profile, a distance between the closing wall and the connecting wall may be less than or equal to 20 millimeters.

Abstract: A winding structure includes two automatic winding mechanisms each including a side plate, a rotary member and an elastic member. The rotary member is provided with a receiving space, a through hole and a first fitting portion. The elastic member is mounted in the receiving space and is disposed at a one way helical state. The elastic member is provided with a clamping portion secured on the side plate and a second fitting portion secured on the first fitting portion of the rotary member. The side plate is provided with an extending portion extending through the through hole of the rotary member. The rotary member is rotated on the extending portion of the side plate and is returned to an original position automatically by the restoring force of the elastic member.

Abstract: A spring roller blind system is provided that has a roller blind module, a height adjusting module, a winding module, a first main adjusting device disposed on the height adjusting module, a second main adjusting device disposed on the winding module, an auxiliary adjusting element, and a fixing element. The height adjusting module and the winding module are respectively disposed on two ends of the roller blind module. The auxiliary adjusting element is selectively and detachably disposed on a first main adjusting element of the first main adjusting device or a second main adjusting element of the second main adjusting device for adjusting the height adjusting module or the winding module. The fixing element is selectively inserted into a fixing recess of the winding module for positioning the second main adjusting element.

Abstract: A curtain controller structure includes a fixing seat, an assembling seat having an accommodation space formed between the fixing seat and the assembling seat. The assembling seat includes a first chamber. A bead chain disc is disposed in the accommodation space. A first driving assembly is disposed in the first chamber of the assembling seat and has a first driving unit and a second driving unit. A traction string is connected to the first driving unit or the second driving unit of the first driving assembly and the bead chain disc.
