ANGLE REGULATOR OF ELECTROMOTIVE BLIND

摘要

PURPOSE: An angle regulator of an electromotive blind is provided to operate a blind and to regulate an angle of a blind simultaneously using one driving motor and to cut down expenses by simplifying the whole structure. CONSTITUTION: In the electromotive blind which comprises a fixed frame(1) fixed on the upper part of a window, a housing unit(2) coupled on the fixed frame(1), a rotary bar(3) supported by the housing unit(2) by the power from a driving motor(9), many blind wings(5) operated vertically by winding or unwinding a control belt(6) by the rotary bar(3), and a bearing belt(7) supporting each blind wing(5) to be operated, the angle regulator of the electromotive blind contains a primary movable cam(12) attached on one end of a rotary shaft(11) fitted axially to the rotary bar(3), a rotary angle control member for making the primary movable cam(12) take the motive force from the rotary bar(3), and a secondary movable cam(13) whose cam shaft(13a) is coupled with the uppermost wing(5') of the blind wings(5) connected with the primary movable cam(12) by a connecting link(14) to take motive force.
