Title: Sealed magnetic-controlled window blind between two panes of glass

Description:
FIELD OF THE INVENTION 
     The present invention relates to a sealed magnetic-controlled window blind between two panes of glass. 
     BACKGROUND OF THE INVENTION 
     There are three kinds of the conventional magnetic-controlled window blinds. The first kind of the conventional magnetic-controlled window blinds is that the light modulation device and the raising device are separated. The light modulation device is mounted at a top portion of the window blind. The raising device is mounted at a left side or a right side of the window blind. The disadvantage is that the light modulation device is hard to be operated while the window blind is too high. 
     The second kind thereof is that the light modulation device and the raising device are mounted at the left side and the right side of the window blind respectively. The disadvantage is that the user must move to different sides to operate the light modulation device and the raising device which are mounted at the left side and the right side of the window blind. It is inconvenient. 
     The third kind thereof is that the light modulation device is integrated with the raising device. That is, the light modulation device is assembled with the raising device, and an outside control bar is exposed outside to control them for performing light modulation, raising and lowering the window blind. Because the leaves are closed, the pull cord will rub against the aluminum plate while raising the window blind. There will be much dust staying on the pull cord and the leaves and the window blind may become dirty. 
     Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a sealed magnetic-controlled window blind between two panes of glass.

     Referring now to the drawings where like characteristics and features among the various figures are denoted by like reference characters. 
     Please refer to  FIGS. 1 to 3 , the sealed magnetic-controlled window blind between two panes of glass according to the present invention comprises a blind body, a frame, and a control system. 
     The bind body includes a head rail set  10 , a pulley set  11 , a plurality of leaves  29 , a bottom rail  30 , and a ladder cord  28 . 
     The frame includes an upper portion  2 , a right side portion  4 , a left side portion  8 , a left side rail  9 , a lower portion  6 , and a lower rail  7 . The upper portion  2 , the right side portion  4 , the left side portion  8 , and the lower portion  6  are connected with one another by corner connectors. The blind body is fastened to the upper portion  2  of the frame through the head rail set. The left side portion  8  and the left side rail  9  may be engaged with each other. The lower portion  6  and the lower rail  7  may be engaged with each other. A desiccant may be arranged inside a sealed space which is defined in the left side portion  8  and the lower portion  6  so as to make sure that the sealed space is dry and prevent the glass from fogging. The lower rail  7  and the left side rail  9  have a U-shaped groove respectively. The leaves  29  may be received in the U-shaped grooves to shield the light leakage between the leaves  29  and the frame. 
     The control system comprises a raising inside control set  23 , a raising outside control set  18 , a raising cord set  24 , a light modulation inside control set  22 , a gyroscope  20 , a light modulation outside control set  19 , a spring  21 , a light modulation cord set  25 , a corner set, an iron bar  27 , an inner rail  16 , and an outer rail  17 . The corner set includes a light modulation wheel  12 , a light modulation bearing  13 , a corner body  14 , a pulley  26 , and a light modulation cover  15 . The inner rail  16  is fastened to the right side portion  4 . The outer rail  17  is stuck to the glass by a double-side tape. 
     When raising the window blind, it may be performed by the inner rail  16 , the raising cord set  24 , and the corner set. The inner rail  16  and the outer rail  17  may make sure that the raising inside control set  13  and the raising outside control set  18  are only moved up and down but not left and right. One end of the raising cord set  24  is fastened on the bottom rail, passing through at least one blind hole of the leaves and the iron core of the pulley set  11  to turn an angle of 90 degree, turned an angle of 90 degree downwardly by the corner set, passing through the pulley which is arranged on the raising inside control set  13  to turn an angle of 90 degree upwardly, and then fastened on the corner set to form a combination of a fixed pulley (the pulley on the corner set) and a movable pulley (the pulley on the raising inside control set  13 ). When the raising outside control set  18  is moved on the outer rail  17  downwardly, the raising inside control set  13  is moved with the raising outside control set  18  downwardly due to the magnetic attraction between the raising outside control set  18  and the raising inside control set  13 . The pull cord which is arranged inside the inner rail  16  is moved downwardly due to the downward movement of the raising inside control set  13  so as to raise the window blind. When the raising outside control set  18  is moved upwardly, the raising inside control set  13  is also moved upwardly due to the magnetic attraction. The pull cord which is arranged in the inner rail  16  is released and the sides of the window blind are moved downwardly due to the gravity of the leaves and the bottom rail. According to above mentioned structure and operation, raising or lowering the window blind which is sealed between two panes of glass is performed by the magnetic attraction between the between the raising outside control set  18  and the raising inside control set  13  (the magnets may be used). In addition, the operation of raising or lowering the window blind may be smooth due to the arrangement of the pulleys (or bearing) which are arranged on the raising inside control set  13  and the outside control set  17 . The raising outside control set  18  may have a T-shaped buckle which may cooperate with a T-shaped groove of the outer rail  17  to make sure that the raising outside control set  18  is moved along a direction of the outer rail  17 . 
     A light modulation system of the window blind comprises the light modulation inside control set  22 , the gyroscope  20 , the light modulation outside control set  19 , the spring  21 , the light modulation cord set  25 , the corner set, the iron bar  27 , the inner rail  16 , and the outer rail  17 . One end of the light modulation cord set  25  is fastened to a bottom end of the light modulation inside control set  22 , the other end of the light modulation cord set  25  is fastened to an upper end of the spring  21  which is arranged under the light modulation cord set  25 , a bottom end of the spring  21  is fastened to the pull cord, the pull cord is extended downwardly to the gyroscope  20  to turn an angle of 180 degree to extend upwardly, the pull cord is winded around the light modulation wheel  12  with an angle of 180 degree to extended downwardly, and then the pull cord is fastened to a top end of the light modulation inside control set  22  to form a light modulation circulation. The magnets may be arranged at the light modulation inside control set  22  and the light modulation outside control set  19 . When the light modulation outside control set  19  is moved up and down, the light modulation inside control set  22  is moved with the light modulation outside control set  19  up and down and drives the pull cord to move. The light modulation wheel  12  is driven by the pull cord to rotate through the light modulation cord set  25 , the iron bar  27  is driven by the light modulation wheel  12  to rotate, the pulley set  11  is driven by the iron bar  27  to rotate, and then the ladder cord  28  is driven by the pulley set  11  to perform the function of light modulation. Besides, the operation of raising or lowering the window blind may be smooth due to the arrangement of the pulleys (or bearing) which are arranged on the raising inside control set  13  and the outside control set  17 . The spring  21  may make sure that the tension of the pull cord is enough. The bearing  13  may make sure that the light modulation is smooth. The light modulation cover  15  may make sure that the pull cord will not be separated. The light modulation inside control set  22  and the light modulation outside control set  19  may be arranged at an upper end or a lower end of the raising inside control set  13  and the raising outside control set  17  if necessary.
