Description of the new type: [Technical field to which the new type belongs] This creation relates to a shutter opening and closing device for a jalousie, which is built into the upper beam and can be controlled with two ladder ropes and pulls on each side. As a device for opening, closing, and retracting the curtain, it can be applied to various wide-diameter blinds with different wire diameters and ladder ropes of different shapes, which can achieve smooth and smooth opening and closing of the curtain and Saver. [Prior art] * Press ", please refer to the first and second pictures. It is known that one is to control the two ladder ropes (A) and pull ropes (magic curtains) on each side of the jalousie. The film opening and closing and retracting device is composed of a receiving seat (10), a sliding seat (20), a spool (30), and an outer cylinder (40). The receiving seat (10) is installed on the upper seat. Inside the beam (0, there is an accommodation area (101) for the outer cylinder (40) to set therebetween.) The accommodation area (101)-one end is for the outer cylinder (40) to pass through, and the other end is open. Li L102) and the positioning portion (103), and the through hole (102) is for two ladder ropes (A / through), and the positioning portion (103) is for the sliding seat (20) to be placed in between; the sliding seat ( 2) For the reel (30) to pass through and have a middle hole (201) for the drawstring (B) to pass out of the seat (10), a continuous groove is formed on the periphery of the reel (30) (301), with a perforation (302) for one end of the drawstring (β) to be fixed; the outer tube (40) is sleeved on the outside of the spool (30) and positioned at the receiving seat (10) In the accommodation area (101), a ring-shaped recess (401) is formed on the outer cylinder (40) for the ladder rope (Α). However, the outer cylinder (40) provided in the above-mentioned curtain opening and closing and retracting device is a ring-shaped recess (40) for the ladder rope (A), and a winding rope (0) for winding. Between the inner diameter of the outer cylinder (40) and the outer diameter of the spool (30), the limits for the use of the predetermined [thin strip] wire diameter M269349 and the ladder rope (A) and The rope (b) [as shown in the third figure], since the annular recess (401) of the outer cylinder (40) and the fixed wire diameter of the two ladder ropes are in close contact,
合，故倘若所使用之梯繩（A)線徑超過固定線徑之大〔或 小〕，那麼其過大〔或小〕之梯繩（A)線徑則與環狀凹部（4〇1) 間的接觸面積小，相對磨擦力不足〔如第四圖所示〕，以 致梯繩（A)受拉動時受阻而使轉動不順暢，造成簾片開啟和 關閉中有不元全之問題；再加上拉繩（B)的固定線徑係容置 外筒（40)内徑與捲線筒（3〇)外徑間，倘若另外使用超過固 定線徑為大之其他拉繩，則易致否則會因外筒（4〇)包覆捲 線筒（30)之間產生有阻礙之摩擦力，致使外筒（4〇)轉動遲 純，而影響影響簾片收放中亦有作動不順暢之情形。 ，爹閱第五圖所示，習知其二為使用較大百葉窗簾規 格〔，幅Y之較粗線徑的梯繩及拉繩，為考量其所承載能 力不影響簾片啟閉和收放操作的順暢，故其必須將簾片之 啟閉用寿簾片之收放用的操作方面，各別獨立形成簾片之 啟閉裝置(70)及簾片之收放裝置⑽），企圖改善上述簾片 啟閉、收放I置不適用較粗線徑的梯繩及拉繩之缺失。Therefore, if the wire diameter of the ladder rope (A) used is larger (or smaller) than the fixed wire diameter, the wire diameter of the ladder rope (A) that is too large [or small] is the same as that of the annular recess (401). The contact area between them is small, and the relative friction force is insufficient [as shown in the fourth figure], so that the ladder rope (A) is blocked when it is pulled and the rotation is not smooth, resulting in incompleteness in the opening and closing of the curtain; In addition, the fixed wire diameter of the drawstring (B) accommodates the inner diameter of the outer cylinder (40) and the outer diameter of the spool (30). If other drawstrings larger than the fixed wire diameter are used, it is easy to cause otherwise. The friction between the outer cylinder (40) and the winding reel (30) will cause obstruction, which will cause the late rotation of the outer cylinder (40), which will affect the operation of the curtain. . As shown in the fifth figure, the second one is the use of larger jalousie specifications [, ladder ropes and pull ropes with a larger diameter of Y, for consideration of its carrying capacity will not affect the opening and closing and closing of the curtain The opening and closing operation is smooth, so it must be used to open and close the shutters. For the operation of the retracting and unwinding of the curtains, the shutter opening and closing device (70) and the shutter retracting device ⑽) are independently formed. Improve the lack of opening and closing and rewinding of the curtains, which are not applicable to ladder ropes and pull ropes with larger wire diameters.
