IMPROVED INFRARED REMOTE CONTROL, DEVICE FOR VENETIAN BLIND
AND CURTAIN
BACRGQOU~D I THY E~TION
The present invention relates to an improved infrared remote control device for Venetian blind and curtain, more particularly, to a remote / manual control device for Venetian blind and curtain.
Venetian blind and curtain are usually used to regulate outdoor light rays shining into a house. As they help to iTn~ediately iTnprove the indoor atTnosphere. Their variety in colors and patterns effect a good decoration, Venetian blind and curtain therefore become a favorite in the modern interior decoration field.
Conventional Venetian blind and curtain include two pull ropes. One of the pull ropes is horizontally oriented and pulls the slats or cloth to spread across a window or retreat. The other one is a directional pull rope and adjusts the angular position of the slats. Generally, these two pull ropes are controlled by manual operation and it is not a trouble for a norTnal person to draw a blind or curtain by hands. However, it is still an inconvenience for the in-house patients, elders and those who are inconvenient to Jove, and Tore particularly, if a window is located at a 7 AL l. L
high level, thy associated blind or curtain is more inconvenient to operate by hands.
Therefore the present invention is based on the problem stated above to provide an infrared remote control device for Venetian blind and curtain such that it no longer has the disadvantages described above.
UREA OF THE INVENTION
The infrared revote control device is attached to the Venetian blind and curtain to raise or to lower the Venetian blind and curtain, and to adjust angular position of the slats through a remote control or the basic manual operation remained as an alternative way of operation in case of power failure.
The main object of the present invention is to provide an infrared remote/manual control device for Venetian blind or curtain to wake drawing blind or curtain easy for the elders and those who are stall and weak.
