A blind assembly includes a headrail, a guide member carried by the headrail and defining a channel therethrough, a tilt basket received within the channel, first and second cords operatively engaging a number of blind slats and extending from the number of slats upwardly through the tilt basket with the first cord coupled to the guide member adjacent to one terminal end of the channel and the second cord coupled to the guide member adjacent to an opposite terminal end of the channel, and an actuator to cause relative movement between the tilt basket and the elongated guide member along the channel to adjust a tilt angle of the number of slats between a full forward tilt with the tilt basket abutting one terminal end of the channel and a full rearward tilt with the tilt basket abutting the opposite terminal end of the channel.

A window blind includes an outer framework and a blind unit. The outer framework defines a retaining space therein, and has two open grooves in spatial communication with the retaining space. The blind unit includes a plurality of slats and two ladder strings. Each of the slats has an intermediate portion, and two end portions respectively extending into the open grooves of the outer framework. Each of the ladder strings is retained in a respective one of the open grooves, and interconnects the corresponding end portions of the slats retained in the respective one of the open grooves.

A locking device for window blind between two panes of glass is disclosed. The window blind is arranged between tow panes of glass through the attraction of the inside magnet and the outside magnet to transmit power to control the operation of the window blind. The locking device may achieve the effects of controlling smoothly and stopping firmly. The locking device may comprise a control shaft and a track. The control shaft includes a locking body, a switch, a hook, a spring, a bearing, and a magnet. The control shaft may be connected with the track through a hook position. The window blind is controlled by attraction of the inside magnet and the outside magnet to achieve the effects of control of raising and lowering the window blind between two panes of glass and light modulation. The locking device is controlled the engagement and disengagement between the hook and the track by the switch to ensure the window blind stopping at any position and without sliding down.

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.

The present invention concerns a system for screening a fixture, such as a Venetian blind in a double glazing, comprising at least one screening element, and a transmission system connected to it for moving it between different operating positions and causing different levels of screening of the fixture. The transmission system comprises two pulleys and a transmission belt with a toothing for meshing with at least a first pulley. A barrier element, for example a U-shaped or closed profile, is arranged between the pulleys and is interposed between two longitudinal sections of the belt to prevent contact between distinct portions of the toothing of the belt.

A louver-blind double glazed window unit comprises a frame defining first and second faces of the unit with respective first and second windows mounted thereto, and outer side and inner sides. An inner chamber is defined between the frame and the first and second windows. Louvers extend within the chamber and are pivotally mounted to the frame. An actuator assembly is positioned within an operating part of the frame for pivoting the louvers between open and closed positions. An inner magnet is positioned at the inner side of the frame. An external manual operator is movably positioned on the outer side of the frame and comprises an outer magnet magnetically communicating with the inner magnet. Moving the external manual operator along the outer side of the frame causes the inner magnet to move in tandem therewith thereby actuating the actuator assembly to pivot the plurality of louver members.
