FIELD OF THE INVENTION  
         [0001]    The present invention relates to a power saving device for adjusting shutter ropes, wherein other than pulling a shutter with less power, the shutter can be assembled easily.  
         BACKGROUND OF THE INVENTION  
         [0002]    The shutters with large sizes can not be used to replace cloth window curtains due to a large force being necessary for operating the rope. The current power saving device of shutter has pulleys in the plug at the lower beam. The ropes pass through the same holes of blades so that the holes must be prolonged. Other than difficult in assembly, the strength of the blades must be weakened. If to save more power, the length of the rope must be prolonged with an inverse ratio to the saved power. Therefore, a too long rope makes the outlook of the shutter not beautiful. Furthermore, the operation is inconvenient.  
         SUMMARY OF THE INVENTION  
         [0003]    Accordingly, the primary object of the present invention is to provide a power saving device for adjusting shutter ropes, wherein other than pulling a shutter with less power, the shutter can be assembled easily.  
           [0004]    To achieve the object, the present invention provides a power saving device for adjusting shutter ropes and the method of the same comprising:  
           [0005]    An upper beam is embedded with a plurality of pulley boxes, an ohms, a plurality of winding boxes and a rope retaining seat; wherein each winding box has a rolling shaft; and the rope retaining seat has a balance strip;  
           [0006]    A lower beam has a plurality of holes and a plurality of pulleys;  
           [0007]    A plurality of blades each has holes;  
           [0008]    Wherein winding boxes are classified two sets. The two winding box set are symmetrical to a center of the upper beam and each winding box set is fixed with a rope. The two ropes pass through respective holes on the blades, and then winds through a first pulley on the lower beam; and then extends and winds through a second pulley of the same set with the first pulley on the lower beam; then the two ropes passes upwards through the respect holes on the blades, and then passes through the upper sides of rolling shaft below the winding boxes, the two ropes pass through outlets at an upper and a lower side of the balance strip; and then the two ropes are combined as one first combine rope; then the first combined rope passes through an opening at another side of the rope retaining seat to be formed as a second combined rope, this second combined rope is combined with the first combined rope at the outlets of the rope retaining seat to be as a combined rope; when this combined rope is pulled, one end of the rope will left the shutter, and another end of the rope receives the rope to be in an inner space of the upper beam.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0030]    In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.  
         [0031]    Referring to FIGS. 1, 2,  16 ,  17 ,  18 , and  19 . The upper beam  5  is sequentially embedded with a pulley box  1 , an ohm  2 , a winding box  31 , a winding box  32 , a winding box  33 , a winding box  34 , and a rope retainer  4 . The pulley box  1  is installed with a pulley  1   a . The ohm  2  has a guide groove  21 , a guide groove  22 , a hook  23 , a rotary rod  24  and a link shaft  25  penetrating through the winding box  31 , winding box  32 , winding box  33  and winding box  34 .  
         [0032]    The winding box  31  is installed with a guide groove  311 , a guide groove  312 , a guide groove  313 , and a rolling shaft  31   a . The winding box  32  is installed with a guide groove  321 , guide groove  322 , guide groove  323 , and rolling shaft  32   a . The winding box  33  is installed with a guide groove  331 , a guide groove  332 , a guide groove  333 , and a rolling shaft  33   a . The winding box  34  is installed with a guide groove  341 , a guide groove  342 , a guide groove  343 , and a rolling shaft  34   a.    
         [0033]    The rope retainer  4  is formed with an opening  41 , and an opening  42 , a balance strip  43 , an outlet  44 , a fixing wheel  45  and a fixing wheel  46 .  
         [0034]    The blade  61 , blade  62 , blade  63 , blade  64 , blade  65  and blade  66  are passed by the ladder rope  11 , ladder rope  12 , ladder rope  13  and ladder rope  14 . The upper ends of the ladder rope  11 , ladder rope  12 , ladder rope  13  and ladder rope  14  pass through the hole  5   a , hole  5   c , hole  5   d , hole  5   f , hole  5   g , hole  5   i , hole  5   j  and hole  51  of the upper beam  5  to be fixed to the winding box  31 , winding box  32 , winding box  33 , and winding box  34 . The lower ends thereof are fixed to the holes (such as hole  75   a  with respect to the winding box  31 , and the hole  75   b  with respect to the winding box  32 ) of the lower beam  7   x  with respect to the winding box  31 , winding box  32 , winding box  33 , and winding box  34  by the plug  91 , plug  92 , plug  93  and plug  94 . The shaft  811 , shaft  821 , shaft  831 , and shaft  841  pass through the pulley  810 , pulley  820 , pulley  830 , and pulley  840  to be fixed to the lower beam  7   x.    
         [0035]    The winding box  31  and winding box  32  are classified as one set and winding box  33  and winding box  34  are as another set. The rope  15  is fixed to the rolling shaft  32   a  of the winding box  32  and then passes downwards through the hole  5   e  and the blade  61 , blade  62 , blade  63 , blade  64 , blade  65  and blade  66  at positions with respect to the hole  5   e . Then, it winds through the right side of the pulley  820  on the lower beam  7   x  and then passes through the holes of the blade  61 , blade  62 , blade  63 , blade  64 , blade  65  and blade  66  with respect to the hole  5   b , and then passes through the rolling shaft  31   a , guide groove  313 , guide groove  323 , guide groove  333 , and guide groove  343  to the outlet  44  of the rope retaining seat  4 . The rope  16  is fixed to the rolling shaft  33   a  of the winding box  33 , and then passes through the holes  5   b  and holes of blade  61 , blade  62 , blade  63 , blade  64 , blade  65  and blade  66  with respect to the hole  5   b . Then it passes through the left side of the pulley  830  on the lower beam  7   x  and then from the right side of the pulley  840  passes upwards through the holes of the blade  61 , blade  62 , blade  63 , blade  64 , blade  65  and blade  66  with respect to the hole  5   k  and the hole  5   k . Then it passes through the rolling shaft  34   a , and guide groove  343  of the winding box  34  to the outlet  44  of the rope retaining seat  4 .  
         [0036]    Then the rope  15  and rope  16  are combined and fixed out of the outlet  44 . The extension of the ropes  15  and  16  are formed as a rope  17 . The rope  17  passes through the opening  42  to enter into the upper beam  5 . Then it passes through the guide groove  341 , guide groove  331 , guide groove  321 , guide groove  311 , and guide groove  21  to pass through the pulley  1   a  and then it passes through the guide groove  22 , guide groove  312 , guide groove  322 , guide groove  332 , and guide groove  342 . Then it passes out from the opening  41  and passes through the fixing ring  47  with the original section of the rope  17  and is combined therewith.  
         [0037]    When the fixing ring  47  or the rope  17  below the fixing ring  47  is pulled leftwards and downwards, the rope  15 , rope  16  and rope  17  are also pulled. The rope  16  and rope  17  lift the lower beam  7  (shutter) upwards. The rope  17  stores the rope  15  and rope  16  in the inner space of the upper beam  5  along the periphery of the upper beam  5 . If the rope  17  is released rightwards and upwards, then the rope  15  and rope  16  are buckled between the fixing wheel  45  and fixing wheel  46 . Therefore, other than power being saved and assembling easily, the rope can be stored.  
         [0038]    With reference to FIGS. 3 and 4, in the lower beam  7 , the pulley  810  and pulley  820  are classified as one set and are installed with an upper left panel  71 , an upper right panel  72 , a left panel  73 , a hole  73   a , a right panel  74 , a hole  74   a , a hole  74   b , a hole  75   a , and a hole  75   b . The shaft  811  and shaft  821  pass through the pulley  810  and pulley  820  to be fixed to the lower beam  7   x . The rope  15  winds downwards through the right side of the pulley  820  and upwards from the left side of the pulley  810 . The hole  75   a  and hole  75   b  on the bottom plate  75  may be inserted by plug  91  and plug  92  so as to fix the ladder rope  11  and ladder rope  12  in the lower beam  7   x . The upper left panel  71  and upper right panel  72  can suffer from the weight of the blade  61 , blade  62 , blade  63 , blade  64 , blade  65  and blade  66  so as not to deform.  
         [0039]    Referring to FIGS. 5, 6 and  7 , FIG. 5 is an exploded perspective view of the second preferred embodiment of the present invention. The difference of this embodiment from the first embodiment is that the structure of the lower beam  7   y  is different from the lower beam  7   x , while the other parts are identical.  
         [0040]    In the lower beam  7   y , the pulley  810  and pulley  820  are formed as one set and have an upper left panel  7   a , a flange  7   a   1 , an upper right panel  7   b , a flange  7   b   1 , a middle plate  7   c , a bottom plate  7   d , a hole  7   d   1 , a hole  7   d   2 , plug  71   a , a flange  71   a   1 , a plug  71   b , a flange  71   b   1 , an opening  714 , an opening  715 , a plug  72   a , a flange  72   a   1 , a plug  72   b , a flange  72   b   1 , an opening  724 , an opening  725 . The rope  15  passes downwards through the right side of the pulley  820  and then passes upwards from the left side of the pulley  810 . The hole  7   d   1  and hole  7   d   2  on the bottom plate  7   d  can be inserted by the plug  91  and plug  92  so as to fix the ladder rope  11  and ladder rope  12  in the lower beam  7   y . The upper left panel  7   a  and upper right panel  7   b  can suffer from the weight of the blade  61 , blade  62 , blade  63 , blade  64 , blade  65  and blade  66  so as not to deform. Other than increasing the strength of the lower beam  7   y , the middle plate  7   c  has the function of fixing the plug  71   a , plug  71   b , plug  72   a  and plug  72   b.    
         [0041]    In assembly, the shaft  811  and shaft  821  pass through the pulley  810  and pulley  820  and then enter into the lower side of the upper left panel  7   a  and upper right panel  7   b  through the opening  714 , opening  715 , opening  724  and opening  725 . Then the plug  71   a , plug  71   b , plug  72   a  and plug  72   b  are embedded into the opening  714 , opening  715 , opening  724  and opening  725 . The flange  7   a   1 , flange  7   b   1 , flange  71   a   1 , flange  71   b   1 , flange  72   a   1 , and flange  72   b   1  serve to retain the shaft  811  and shaft  812  to be in proper positions in the lower beam  7   y.    
         [0042]    The shaft  831  and shaft  841  pass through the pulley  830  and pulley  840  to enter into the lower beam  7   y  to be formed as another set. The structure is identical to the set formed by the pulley  810  and pulley  820 .  
         [0043]    As shown in FIG. 8, a schematic perspective view of the plug  91  is illustrated. The plug  9  has a round cylinder  911 , a groove  911   a , a groove  911   b , and a round sleeve  912 . The structures of the plug  92 , plug  93 , and plug  94  are identical to that of the plug  91 .  
         [0044]    Referring to FIGS. 9, 10,  11 , and  12 , FIG. 9 is an exploded perspective view of the preferred embodiment of the present invention. The difference of FIG. 9 from the first embodiment illustrated in FIG. 1 is that the lower beam  7  has a coupling means  81 , a coupling means  82 , a coupling means  83  and a coupling means  84  which are coupled thereon. The other parts are identical.  
         [0045]    In the lower beam  7 , the coupling means  81  and coupling means  82  are formed as a set and have a pulley  810 , a shaft  811 , a shaft  812 , an upper left panel  81   a , an upper right panel  81   b , a left panel  81   c , a hole  81   c   1 , a hole  81   c   2 , a right panel  81   d , a hole  81   d   1 , a hole  81   d   2 , a bottom plate  81   e , a hole  81   e   1 , a pulley  820 , a shaft  821  a shaft  822 , an upper left panel  82   a , an upper right panel  82   b , a left panel  82   c , a right panel  82   d , a hole  82   d   1 , a hole  82   d   2 , a bottom plate  82   e , a hole  82   e   1 , etc. The bottom of the lower beam  7  has a hole  713 , a hole  723 , a hole  733  and a hole  743  with respect to the a coupling means  81 , a coupling means  82 , a coupling means  83  and a coupling means  84 .

The shaft  811  and shaft  821  pass through the pulley  810  and pulley  820  and then are fixed to the coupling means  81  and coupling means  82 . The rope  15  winds through the right side of the pulley  820  and then passes upwards from the left side of the pulley  810 . The shaft  812  penetrates thereby the hole  81   d   1  and hole  912   a , hole  81   c   2  and the lower beam  7  for enhancing the fixedness between the coupling means  81  and lower beam  7 . Similarly, the coupling means  82 , coupling means  83  and coupling means  84  have respective shafts passing through the lower beam  7 , plug  92   a , plug  93   a  and plug  94   a  to enhance the fixedness between the coupling means  82 , coupling means  83 , coupling means  84  and lower beam  7 .

         [0052]    A schematic perspective view of the blade  61  is illustrated in FIG. 20, the blade  61  has hole  611 , hole  612 , hole  613  and hole  614  which are channel of the rope  15  and rope  16 . Similarly, the blade  62 , blade  63 , blade  64 , blade  65 , blade  66  have respective holes.  
         [0053]    By above structure of the present invention, in practical utilization, the number of the winding boxes of each rope set can be changed with the number of the winding box of each product. If the number of the winding box is six, then the first, second and third winding boxes are classified as one set, and the fourth, fifth and sixth winding boxes are classified as one set. If the If the number of the winding box is five, then the first, second winding boxes are classified as one set, and the fourth, fifth winding boxes are classified as one set. The space for receiving the ropes can be installed at any space for receiving the rope, such as the upper side or lower side or front side or the rear side of the upper beam. The constructions are identical to the former.  
         [0054]    The present invention are thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.

Summary:
A power saving method for adjusting shutter ropes and the device of the same are disclosed. Winding boxes are classified into two sets. Two winding box sets are symmetrical to a center of the upper beam and each winding box set is fixed with a rope. The two ropes pass through respective holes on the blades, and then winds through a first pulley on the lower beam; and then extends and winds through a second pulley. Then the two ropes passes upwards through the respect holes on the blades. Then the two ropes pass through the outlets of the balance strip; and then are combined as one first combine rope. Then the first combined rope passes through an opening of the rope retaining seat to be formed as a second combined rope. This second combined rope is combined with the first combined rope at the outlets of the rope retaining seat.
