A stop structure for a cordless curtain includes a bracket, a mounting seat, a rotation wheel, a locking piece, and a spring. The bracket has a resting portion. The mounting seat has an axle. The rotation wheel is mounted on the axle and has at least one positioning hole. The locking piece is rotatably mounted on the mounting seat and has a first end provided with a positioning projection positioned in the at least one positioning hole. A push member is biased between a second end of the locking piece and the mounting seat. When the resting portion presses the locking piece, the positioning projection is detached from the at least one positioning hole. The spring is mounted in the rotation wheel and connected with the rotation wheel and the axle.

The invention relates to an operating mechanism for a cordless window covering such as a roller blind, comprising at least one substantially stationary inner shaft which is connectable to the fixed world and at least one axially rotatable drive shaft configured for driving and thereby lowering and/or raising the window covering. The system is in particular configured to provide controlled operation of a cordless window covering.

A retractable, coilable, security barrier screen easily mounted around a door, window or other building opening such as a hallway entrance. The barrier is designed to withstand considerable forces from blunt force strikes, bullets and edged weapon slashing. As such, it has a strengthened spool tube, novel security barrier attachment methods, and redundant operational features such as dual (top and bottom spool locks), quad spool locking pins and a dual attachment for the fabric security barrier to the screen lock strip that includes both gluing and plate riveting.

The present disclosure relates to a system for supporting a roller clutch assembly for a fabric covering. The system includes a housing assembly with a first side, a second side, a third side, and a fourth side. At least one of the first, second, third, and fourth sides defines a mounting interface of the housing assembly within a depth of the housing assembly. The system also includes a bracket received within the depth of the housing assembly and which is removably coupled to the mounting interface.

An opening/closing direction restriction mechanism for a manual shutter device and an opening/closing direction restriction mechanism for a suspended sliding door device. This opening/closing direction restriction mechanism is provided with: a flange fixedly mounted on a fixed shaft; a bracket which is loosely fitted to the fixed shaft and can be integrally rotated with a winding member; and a two-way clutch which can be switched between a reverse rotation inhibited state in which the revolution of a planetary external gear along a winding direction of the winding member is allowed and the revolution of the planetary external gear along an unwinding direction is inhibited, and a forward rotation inhibited state in which the revolution of the planetary external gear along the winding direction of the winding member is inhibited and the revolution of the planetary external gear along the unwinding direction is allowed.

A method of covering a cavity window with an external awning, including the steps of: providing an awning, the awning having a flexible mesh screen and a spring loaded roller drum mounted along a bottom end thereof and around which the screen can be wound so that the awning can be selectively operated, the screen being sized to extend within the cavity in which the window is fitted and substantially across the width and height of the cavity; securing a mounting bracket to a lintel extending across an upper portion of the cavity, the bracket being disposed within the cavity and configured for securing an upper end of the awning within the cavity; securing an upper end of the awning to the bracket; and securing a lower end of the awning to a lower portion of the cavity to cover the window.

A door curtain anti-dropping device for a rolling door is provided. The device comprises a worm shaft connected to the output shaft of the door operator, and a drive shaft comprising a limiting disc with through holes. The worm wheel having receiving slots is fixed on the drive shaft to mesh with the worm. The driven wheel is disposed adjacent to the limiting disc. Baffle plates designed to cover the through holes and receiving slots extend from the driven wheel. Plural latching pins stored with spring potential energy are compressed by the baffle plates and retained in the through holes and receiving slots. When the worm wheel is excessively worn and dislocated from the driven wheel, the baffle plates are moved to allow the latching pins to spring out and insert into the notches of the front cover, thereby lock the worm wheel and prevent the winding shaft from rotating.

A multifunction securing mechanism for a compartment closable by a door and includes a key cylinder, a latching assembly which may be a two-point latching assembly movable between a latching and an unlatching position, a rotatable member configured for a lazy-cam function connecting the key cylinder and latching assembly, at least one catch located on a surface adjacent the outside of the door, and a bar pivotally mounted to the outside of the door and movable between a first closed position and a second opened position. A first release mechanism is located on an interior side of the door for changing a positon of the latching assembly, and a second release mechanism is located on the interior side of the door for changing a position of the bar, both for allowing a user to open a latched and secured door from the inside.

The child safety gate system is a modular barricade that forms a barricade in a door selected from a plurality of previously identified doors. The child safety gate system comprises a gate, a plurality of pivot frames and a plurality of latch frames. There is a one to one correspondence between any pivot frame selected from the plurality of pivot frames and a latch frame selected from the plurality of latch frames. Each door contained within the plurality of previously identified doors has installed in it a pivot frame the corresponding latch frame. The selected pivot frame and the corresponding latch frame are used to removably attach the gate to any selected door. This modular behavior allows the installation of the barricade structure in any door selected from the plurality of previously identified doors as required.
