Abstract: A sun screen device includes a pair of slide rails, a screen body, and a pair of rods. Each of the slide rails has an end portion. The screen body has lateral ends, and an operating end that interconnects the lateral ends of the screen body and that is movable along the slide rails. The rods are respectively disposed in the slide rails. Each of the rods has an end portion that is coupled to the end portion of the respective one of the slide rails. Each of the lateral ends of the screen body is formed with a loop that is sleeved on a respective one of the rods.

Abstract: A pull cord device for controlling raising and lowering of a base rail of a window covering includes a locking wheel having a toothed segment turnable between locked and unlocked positions to engage and disengage from a cord spool, respectively, a cord-release controlling member having a cord retaining region to engage a pull cord to be movable along a linear running path when the pull cord is pulled in the unlocked position, a guideway disposed in the locking wheel, and including an angularly extending first route and a looped route, a guided member having a key end disposed in the guideway, and a linkage coupling the controlling member with the locking wheel such that when the controlling member is moved, the locking wheel is turned from the locked position to the unlocked position, and such that, in the unlocked position, the cord retaining region remains unmoved in each of regions in the looped route.

Abstract: A shade roller has a seat, a loop hooked onto the seat, a side cover, a planet wheel engaged with the loop, a chain-retaining wheel secured in the side cover, a driving wheel engaged with the planet wheel, a beaded chain, and a fixing block engaged with the driving wheel. When the beaded chain is pulled, the planet wheel revolves around a fixing pin, and causes the driving wheel and the fixing block to revolve together, whereby a curtain can be raised or lowered.

Abstract: A stacking mechanism for shutter members of a shutter mechanism, comprising: a rotatable screw with external thread of length L and pitch P1; a plurality of N traveling nuts mounted on the screw, having internal thread of pitch P1 and external thread of pitch P2,P1>P2; an arrester preventing rotation of the nuts within a length L1 of the screw, while allowing sliding; and a threaded member of pitch P2 adapted to engage the external thread of the nuts within a length L2 of the screw. In a first position of the mechanism, the nuts are arranged over the length L1. Upon rotation of the screw, the nuts slide along the screw at rate P1 per 1 turn, transit from L1 to L2, and then slide within the length L2 at a rate P2 per 1 turn, thereby achieving reversibly a second position of the mechanism where they are arranged over the length L2,L2<L1.

Abstract: A window blind structure with multiple rods and blinds includes a plurality of support brackets, hook elements, head rails, and blind bodies wherein each support bracket is equipped with a fixing end with multiple fixing thru-holes disposed thereon for the secure engagement of locking screws therewith, and a suspending arm properly extending forwards from the fixing end thereof and provided with a plurality of equally-spaced retaining members each surrounded by a retaining space for the location of a matched hanging rod thereon. Both sides of the retaining member is defined by a set of left/right movement spaces to match with the hook element having a hanging portion to hook onto the hanging rod thereby and an inserting block with indented recesses disposed at the bottom end thereof to engage with an inserting groove disposed at the upper section of the head rail thereby.

Abstract: An assembly includes a housing that has a tubular shape provided with opposed open ends, a planar top surface with spaced apertures adjacent to the ends thereof, and is formed from durable and non-corrosive material. Couplings are insertable into the open ends and are adaptable along a longitudinal axis of the housing. Each coupling has a core provided with a linear bore formed at an angle offset from a vertical axis and a hole formed therein which is positional with an associated one of the apertures. Quick-release pins are insertable into corresponding ones of the apertures and holes, maintaining the couplings at a static relationship with the housing. Coextensive support shafts are interfittable into the bores after the couplings are displaced from the housing. A flexible cord has opposed ends tethered to the support shafts so that the cord maintains a sufficient tension for supporting wet clothes therefrom.
