Title:
DUAL-ROLL BLIND DEVICE HAVING CONTROLLABLE RIGHT AND LEFT LATERAL MOVEMENT DISTANCE
Document Type and Number:
WIPO Patent Application WO/2010/140723
Kind Code:
A1
Abstract:
The present invention relates to a dual-roll blind device having controllable right and left lateral movement distance for adjusting the light-shielding status or the light-transmitting status by restricting the lateral movement distance of the blind. According to the present invention, the rotation members of the movement-adjusting parts rotate along a screw shaft and restrict the transmision of the rotations of the screw shaft to a lateral-moving shaft when the rotations of the screw shaft are below a certain number, which moves a second blind raw material on a set distance up to the width of a light-transmitting part or a light-shielding part. When the rotations are more than this certain number, the rotations of the screw shaft are transmitted to the lateral moving shaft thus restricting further rotations of the screw shaft, thereby precisely measuring the distance of the horizontal movements of the second blind raw material. According to the present invention, a user can easily adjust light-shielding or light-transmitting status, thereby making the device convenient to use, and when the width of the light-transmitting and light-shielding parts is changed, the distance of the movement of the blind raw material can accurately be adjusted accordingly, thereby adapting appropriately.
