DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] Referring to FIGS. 1 to 8, the operation device 10 of the present invention comprises a ladder 11, a receiving element 12, a cord 13 and multiple connecting elements 14. The receiving element 12 accommodates the cord 13 therein. The connecting elements 14 are connected to the ladder 11 and the receiving element 12 to combine the cord 13 and the ladder 11. In other words, the ladder 11, the receiving element 12, the cord 13 and the connecting elements 14 each are a module, and these modules are assembled as needed to easily assemble the operation device 10. Each of the modules has different colors so as to meet aesthetic purposes.

[0032] The receiving element 12 can be a netted element or an enclosed and soft element. If the receiving element 12 is a netted element, the cord 13 can be seen via the netted structure, and the cord 13 cannot be pulled out from the netted element. If the receiving element 12 is an enclosed and soft element, the cord 13 cannot be seen. The cord 13 is accommodated in the receiving element 12 when making the receiving element 12. Alternatively, the cord 13 is accommodated in the receiving element 12 after the receiving element 12 is manufactured. It is noted that the connecting elements 14 can directly extend through the ladder 11 and the receiving element 12. That is to say, the receiving element 12 and the ladder 11 each have holes, so that the connecting elements 14 extend through the holes of the receiving element 12 and the ladder 11. Alternatively, the connecting elements 14 may be sewed to the ladder 11 and the receiving element 12 when the receiving element 12 and the ladder 11 do not have holes. The material and color of the ladder 11, the receiving element 12 the cord 13 and the connecting elements 14 can be varied as needed. When the ladder 11 or the receiving element 12 needs to be replaced, the connecting elements 14 are removed first, and the ladder 11 or the receiving element 12 can be replaced.

[0033] The shutter 1 of the present invention comprises at least one operation device 10, multiple slats 20, a top rail 30, a bottom rail 40, at least one scrolling member 50 and at least one control member 60. The operation device 10 supports the multiple slats 20 between the top rail 30 and the bottom rail 40. The operation device 10 is connected to the scrolling member 50. The cord 13 is connected to the control member 60, and the control member 60 controls the cord 13 to lift or lower the slats 20. The operation device 10 hides the cord 13 to make the shutter be safer than the conventional shutters. The operation device 10 is easily to be manufactured and assembled. The operation device 10 may have at least one scrolling spring to control the cord 13.

[0034] When replacing the cord 13, the connection end 132 of the new cord 13′ is tied to the distal end 131 of the original cord 13. The connection end 132 of the original cord 13 is pulled so as to introduce the new cord 13′ into the receiving element 12. The connection end 132′ of the new cord 13′ is then connected to the scrolling member 50, and the distal end 131′ of the new cord 13′ is fixed to the bottom rail 40. The original cord 13 can be replaced with the new cord 13′ which can be thicker or thinner than the original cord 13.

[0035] The method for manufacturing the operation device 10 for shutters 1 of the present invention comprises:

[0036] a step (a): forming a ladder 11;

[0037] a step (b): forming a receiving element 12, a cord 13 accommodated in the receiving element 12, and

[0038] a step (c): connecting multiple connecting elements 14 to the ladder 11 and the receiving element 12.

[0039] The ladder 11 supports and controls the slats 20 to rotate. The cord 13 is accommodated in the receiving element 12 when making the receiving element 12 in the step (b). Alternatively, the cord 13 is accommodated in the receiving element 12 after the receiving element 12 is manufactured in the step (b).

[0040] The receiving element 12 can be a netted element or an enclosed and soft element. The receiving element 12 can be made of transparent material.

[0041] The connecting elements 14 are sewed to the ladder 11 and the receiving element 12, or the connecting elements 14 extend through the ladder 11 and the receiving element 12 with a distance formed between any adjacent connecting elements 14.

[0042] The receiving element 12, the cord 13 and the connecting elements 14 have different colors or an identical color.

[0043] It is noted that the sequence of the step (b) and the step (c) of the method of the present invention can be changed. The step (b) is proceeded before the step (c) can simplify the manufacturing. If step (c) is proceeded before the step (b), the connecting elements 14 do not penetrate through the cord 13 or press the cord 13.

[0044] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
