A curtain system is described which includes a curtain having a plurality of rod engaging members attached thereto, a plurality of rods each having a first end, and a curtain release mechanism attached to each rod at the first end thereof. The rod engaging members each include a stem having a first end and a second end, the first end of the stem configured for engagement with the curtain release mechanism, and a keyway formed in the stem and proximate the first end of the stem.

A retractable covering for an architectural opening includes a headrail in which a control system is mounted and a fabric suspended from the headrail. The fabric is mounted to be moved laterally between a rolled up retracted position and an extended position across the architectural opening. At least one roller about which the fabric can be wrapped is mounted at an end of the headrail for rotation about a vertical axis, and the system includes a flexible control element that is substantially horizontally disposed for moving the covering between extended and retracted positions.

An electric curtain and a curtain retraction device including a toothed chain; an outer housing; a drive motor, the toothed chain extends into the outer housing; a reducer, a power output end of the drive motor is inserted into the reducer, so as to be connected with the reducer in a transmission way, the reducer has a first power output part; a power output module including a power output shaft, a clutch component and a driving gear, the power output shaft is inserted into the first power output part, so as to be connected with the reducer in a transmission way, the clutch component is arranged between the power output shaft and the driving gear, the driving gear is configured to move the toothed chain. The drive motor, the reducer and the power output module are all coaxially installed inside the outer housing.

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.

This motorized carriage for opening/closing a curtain is able to move along a rail thanks to a friction wheel driven by an electric motor and pivot mounted in a casing containing this electric motor. The casing is provided with at least two members for suspending it from the rail or from the rod, which include a support and/or a base element and at least one pivoting roller. The casing is equipped with at least one housing for partially accommodating and reversibly immobilizing each suspension member, so that the pivoting rollers or the shoes of the suspension members are mounted removably on the casing. The support is mounted, removably and via a rotational movement (F4), in the housing. Elements allow the support to be immobilized about its axis of rotation. The movement assembly (E) includes a casing and at least two sets of two suspension members.

An adjustable mounting bracket for a tension assembly for a continuous looped operator includes a mounting projection defining a projection extending from a surface of the mounting projection, and a bracket member defining a first elongated aperture, the first elongated aperture configured to receive the projection, wherein the projection is configured to slide within the first elongated aperture, and wherein the mounting projection is configured to removably fasten to the bracket member.

A device for opening and closing curtains includes a curtain rail with at least one channel open in the curtain-to-be-hung direction and at least one curtain holding part held movably in the channel in the channel longitudinal direction by guides, for attaching the curtain. The guides are adjustable along the rail via an electric motor drive by a drive mechanism. A laterally-arranged, window-like opening is made in at least one section of the rail profile cross-section, which provides access from outside the rail at least to the channel for the drive mechanism. A structural unit for the electromotive drive and/or a deflection of the drive mechanism is insertable into this opening and fixable therein laterally on the rail for passing the drive mechanism through the region for the electromotive drive and/or the deflection. Also, a method connects an electromotive drive and/or a deflection to the rail profile cross-section.
