A tensioning mechanism for a blind assembly is contemplated. The mechanism includes one or more constant force springs affixed to a frame member so as to hold a belt driver and gear assembly in sufficient tension to translate axial movements of an operator into rotational force sufficient to raise or lower the blind (i.e., sun-blocking elements).

The present disclosure provides for a blind assembly. The blind assembly includes a head rail, a bottom rail, and sun-blocking slots. Pull cords connect the head rail to the bottom rail. The pull cords allow the bottom rail to translate towards the head rail. The pull cords include a first pull cord and a second pull cord. Each of the pull cords are fed through apertures of the bottom rail. The pull cords are tied together after feeding them through the bottom aperture. A user may adjust the bottom rail without having to alter the lengths or knots of the pull cords.

In one embodiment, the present invention relates to a belt tensioning device for a hollow blind that comprises: a holder seat equipped with a lower belt gear on the top portion of the holder, the holder seat is in clearance fit with a lumen of a side frame of the hollow blind and is provided with a group of V-shaped slots from top to bottom therein, each V-shaped slot is equipped with a clip therein, the slip has a width slightly larger than the width of the lumen of the side frame of the hollow blind when being bent. The present invention allows the belt tensioning device to move along a single direction within the side frame of the hollow blind so that the distance between two belt gears can be gradually adjusted, thereby maintaining a proper tensioning force in the belt.

The present invention relates to a built-in sun-shading device of hollow glass. The built-in sun-shading device comprises a cord-winding mechanism, a transmission mechanism controlling the rotation of the cord-winding mechanism and a sun-shading mechanism connected onto the cord-winding mechanism. The cord-winding mechanism comprises a cord-winding shaft, a group of cord-winding propellers are arranged on the cord-winding shaft, the transmission mechanism is connected with the cord-winding mechanism, and the sun-shading mechanism is connected onto the cord-winding propellers. The built-in sun-shading device of the hollow glass, which uses a single cord-winding shaft, can wind a plurality of cords and enable the sun-shading mechanism to be folded and unfolded in a balanced mode. The single cord-winding shaft does not need to move back and forth, is simple in terms of structure and has high assembling efficiency. In addition, the built-in sun-shading device of the hollow glass uses the cords to limit slats from moving to and fro, which thus enables the slats to stack up orderly, reduces contact between the slats and hollow glass, protects the coating film on the surface of the hollow glass and reduces friction. Furthermore, the built-in sun-shading device of the hollow glass uses a handle with frictional damping in one direction and overcomes a phenomenon that the large sun-shading mechanism may easily decline itself due to the large self-weight after being lifted.

Disclosed is a hollow glass built-in sun-shading apparatus, the apparatus comprising a rope winding mechanism, a transmission mechanism for controlling the rotation of the rope winding mechanism, and a sun-shading mechanism connected to the rope winding mechanism, wherein the rope winding mechanism comprises a rope winding shaft (1); a set of rope winding propellers (2) are arranged on the rope winding shaft (1); the transmission mechanism is connected to the rope winding shaft (1); and the sun-shading mechanism is connected to the rope winding propellers (2). Since a single rope winding shaft is used, multiple pull ropes (13) can be wound so as to retract and release the sun-shading mechanism evenly; and the single rope winding shaft does not need to move left and right, thus the structure is simple and the assembly efficiency is high. At the same time, the pull ropes (13) are used to prevent blades (11) from moving back and forth, such that the blades are stacked in order so as to reduce contact and friction with the hollow glass, thus protecting the coating film on the surface of the glass. Furthermore, by using handles (7, 8) with friction damping in one direction, the disadvantage that the large-size sun-shading mechanism easily slides down automatically after raising up due to the relatively high weight is avoided.
