A mosquito net of a compartment of an access of a vehicle with a floor and a riser includes a frame and a curtain connected to the frame. The frame includes a first vertical upright, a top rail and a bottom rail configured to be secured to the vehicle, and a second upright free to slide on the top rail and bottom rail.

The system has a pleated net run by ropes that begin from the same side of the retention case, cross the net and continue upwards to all upper fixed horizontal guide, and are fastened at the upper part of the system. This invention uses wire rope which has one edge fastened at the upper truck, passes horizontally above the net, then parses through the pulley at the upper part of the sliding case, follows a vertical course towards the second pulley at the lower part of the sliding guide, crosses the lower fixed horizontal guide and is fastened on the lower part of the vertical fixed side guide. In case of a system with two or more leaves, this invention uses a ropes' central end component, tension adjusters and a ropes' run component.

A curtain hanging assembly that consists of a curtain assembly able to effect horizontal opening and closing of curtains, and includes two elastic motor units provided with elastic feedback. Interactive dynamics between the two elastic motor units, through linear linkage, respectively cause torque forces produced to be in mutual opposition, enabling the let down area of the curtains to be naturally fixed at any height position.

A blockout blind system includes side tracks fitted with brushes in conjunction with a pelmet fitted with flaps ensure no light can pass around the blind. The flaps and brushes have offset apertures either side of the blind to allow for airflow thus preventing the blind being sucked out or pushed in by open or leaking windows and air conditioning systems. The system also conceals the chain for operating the blind thus eliminating strangulation hazards for children and animals. The design allows the system to be fitted to existing roller blinds.

This roller shade device is provided with: a shade; a shade take-up roller for taking up the shade; wires which are attached to the shade; wire take-up rollers which are disposed with the axial centers thereof offset from the shade take-up roller and which are used for taking up the wires; reversal pulleys for reversing the direction of the wires; tension imparting means for imparting tension to the shade and the wires by application of bias such that the shade take-up roller and the wire take-up rollers are separated from the reversal pulleys; and interlocking rotating means for rotating the shade take-up roller and the wire take-up rollers in an interlocked manner. According to this roller shade device, a large width can be secured for the shade.

The present invention relates to a large-sized external awning system which includes a winch provided at an upper story, a rooftop or the ground of a high-rise building, two guide wires spaced apart at a predetermined distance to be provided in parallel, a plurality of raising and lowering rods provided with wire-passing holes through which the guide wires pass such that the raising and lowering rods are raised and lowered along the guide wires, and an awning coupled to the raising and lowering rods and unfolded so as to block the sunlight when the raising and lowering rods are spaced apart from each other.

A cover opening device of an electric sunshade for a side window is provided for connecting between a base and a protecting cover of the electric sunshade and connecting with a curtain support rod. The cover opening device operates by the curtain support rod mounted with a driving element passing through a pedestal, a linkage rod part connected with an abutted part connecting with the protecting cover to move the abutted part downward by a press of the driving element and to pivot the protecting cover for covering a groove by the linkage rod part, and an elastic element providing resilience force for opening the protecting cover. The cover opening device has a mechanism that opens the protecting cover beforehand and closes the protecting cover afterwards, thereby preventing the curtain from colliding with the protecting cover when the curtain is extending out and rolling up.

A covering for an architectural opening is provided. The covering may include a roller, a shade, and an assembly associated with the roller. The assembly may include a biasing element and a retention element. The biasing element may be operably associated with the roller to selectively rotate the roller. The biasing element may be preloaded. The retention element may be associated with the biasing element. The retention element may be operable to release the preload in the biasing element at an extended shade position.

A roll-up door including a flexible curtain having a front surface, a back surface, a first end coupled to a shaft, a second end opposite the first end, and first and second side edges extending between the first end and the second end, the flexible curtain being moveable between a retracted position wherein the flexible curtain is coiled around the shaft and a deployed position wherein the flexible curtain is uncoiled from the shaft. A first retention band is mounted along at least a portion of the first side edge of the flexible curtain, the first retention band including an inner surface at least partially facing towards the flexible curtain, an outer surface opposite the inner surface, a fixed edge attached to the flexible curtain generally parallel to the first side edge, and a free edge opposite the fixed edge and movable relative to the fixed edge.

A retractable curtain system is provided and includes a curtain support system, a curtain, and a retraction system. The curtain support system includes a pair of outer walls and an upper frame to provide a curtain receiving space. The curtain covers the curtain receiving space and includes a first non-transparent panel and transparent panel connected to the first non-transparent panel. The retraction system is connected to the curtain to lower and raise the transparent panel.
