A lining is provided that covers doors or windows to provide protection against all inclement weather conditions. The lining prevents sunlight or any other type light from entering inside a room. The lining that includes horizontal slotted blinds that are operated manually using a flat cord. The horizontal slotted blinds work using tongue and groove concept.

A roller clutch for a window shade includes a housing, a bead chain wheel, and a roller adapter. Transmission of movement from the bead chain to the roller adapter depends upon the force applied by the bead chain to the roller clutch.

The present invention provides an under-structure of a blind apparatus.

An under-structure of a blind apparatus according to an embodiment of the present invention includes: a first bar that holds the lower end of a screen; a plug that is coupled to an end of the first bar and has a first through-hole at the center; a second bar that receives the first bar and has a slit through which the screen comes out; a cover that is fixed to an end of the second bar and has a second through-hole communicating with the first through-hole; and a wrench plug that is coupled to the outside of the cover and is fitted in the first through-hole through the second through-hole to transmit torque.

A roller blind apparatus comprising a control apparatus; an idle end; and a roller tube located between the control apparatus and the idle end, wherein the control apparatus is coupled to a first corner bracket; the idle end includes one of an idle end spindle and an aperture and a second corner bracket includes the other the idle end spindle and an aperture, wherein the idle end spindle is rotatably mounted within the aperture such that the idle end is rotatably coupled to the second corner bracket; a first frame forming element is located between the first and second brackets; and wherein the frame forming element covers the roller tube.

A control mechanism for a blind suspended by lift cords, said control mechanism comprising a hollow rod articulated to the headrail and accommodating said lift cords extending to an elevation assembly operated by an actuator slidingly received over the rod; wherein upward displacing of the actuator entails lowering of the blind and downwards displacing of the actuator entails raising of the blind, said control mechanism further comprising a friction mechanism for arresting the blind at any respective elevation and a regulation mechanism configured for selectively setting the extent of displacement of the actuator based on the weight of the blind.

A retractable barrier system and method for inhibiting access to designated private and public areas both indoors and outdoor, including retail and warehouse aisles and the like, includes a flexible screen retractable and extensible from a rotatable rod coupled to a mounting member, the mounting member having an attachment mechanism for coupling with a receiving member such as storage rack assembly support post or bracket or the like.

A retractable barrier system for inhibiting access to designated private and public areas both indoors and outdoors, including by way of example but not limitation, retail and warehouse aisles and the like, includes a flexible screen retractable and extensible from a rotatable rod coupled to a mounting member, the mounting member having an attachment mechanism for coupling with a receiving member, wherein a winding mechanism is coupled to the rotatable rod for retractably receiving and extending the flexible screen, the flexible screen is comprised of material having a sufficient modulus of elasticity to promote substantially smooth retractably receiving thereof and may further include tapering between ends thereof, and the winding mechanism may include a guide member having a surface of sufficient diameter oriented substantially perpendicular to the flexible screen to guide the flexible screen upon retractably receiving the screen.
