[Previous technology] —The design of general horizontal jalousie is mostly installed in—horizontal rail—rewinding H 'in order to wind up and suspend a predetermined number of parallel drooping extensions: pull ropes, and these pull ropes are It is used to hang most curtains that can be stacked and unfolded upside down, and provides the sagging weight by the pre-weighted element set under the bottommost curtain. Generally, the number of drawstrings required for horizontal blinds is at least two. Of course, when the length of the curtain sheet is long, the number of drawstrings can be increased as needed. As for the operation of the retractor, most of the winding rods arranged at coaxial intervals are used to retract and suspend each rope separately, that is, when the curtains are to be stacked upwards, they are driven synchronously. Each—the rolls are rolled up to retract the corresponding ropes, and when the curtains are to be unfolded downwards, each of the rolls is driven to suspend the corresponding ropes down synchronously. π U.S. Patent Publication No. 5328113 discloses the winding capacity of the curtain retractor. The main winding up of the curtain retractor is wound around the outer peripheral surface of the reel. The number of turns of the ropes overlap each other, so that when the curtains are to be lowered down, the ropes are stuck due to the overlap and the curtains cannot be lowered smoothly. In order to solve the lack of description, the retractor designed in the Xinli patent case such as Announcement No. 168230, 171008, etc., is convenient to set one of the relative screwing for M269350 to wind up the rope and the outer peripheral surface is provided with a threaded reel. And a rope guide block to solve the aforementioned deficiency '§ When the reel is driven to rotate, the rope guide block is caused to move relative to the shaft in an axial direction, and the cooperation of the rope guide and the rope block is used to make the roll rod in the roll At the same time of pulling the rope, the rope can be wound on the roll along the thread pattern through the relative movement of the guide block and the roll. The design of the retractor mentioned above, although it can regulate the winding of the pulling rope along the thread pattern on the winding rod through the cooperation of the winding rod and the rope guide block, so as to avoid the ropes from overlapping each other during winding, but this design When the curtain operation retractor releases the pull rope, when such curtain sheets are blocked by obstacles and cannot be dropped down, it will form a winding that cannot be smoothly drooped and loosely wound outside the roll rod. When the objects are removed, these curtains will instantly drop and pull down the slack rope, so that the slack rope quickly changes from the slack state to the state tightly tied to the outside of the reel. Because it cannot be sequentially wound on the thread of the reel, it is easy for the ropes to overlap and wind on the outside of the reel. In addition, the surface of the reel is uneven due to the setting of the threads. When the overlap causes jamming, the mutually overlapping parts of the pull rope cannot be relatively axially slid due to the obstruction of the embossed surface of the thread. It is easy to cause the state of the pull rope to be jammed and difficult to unlock, so there is an improvement. Necessary "〇 [new ] Therefore, 'the purpose of this new model is to provide a retractor that can gradually retract and release the pull rope and can reduce the chance of the rope from being jammed when the pull rope is blocked from falling. The retractor is suitable for being installed in a horizontally extending rail frame M269350 for retracting and laying a drawstring. The retractor includes a screw that can be driven into the holder, -The coiled cup 々 and the shaft of the screw are axially connected to the rope guide mechanism for guiding the drawstring. The screw has the opposite 帛 -end. The roll is axially connected to the body in a rotatable manner. The dried first end portion has a connecting end portion close to the screw and a fixed rope end portion away from the β screw # and used to fix the _ end of the draw rope. The rope guide mechanism includes the phase fixing company The & ^, screw seat and a rope guide, the screw seat is screwed to the 4 screw buckle, and can be axially displaced between the first and second ends of the screw due to the rotation of the screw, the guide The rope is parallel to the screw and has a guide: the pulling rope passes through the guide hole and is fixed to the fixed rope end of the winding rod, when When the screw seat is axially displaced relative to the screw between the first and second ends, the guide hole of the guide member is used to guide the displacement of the draw rope between the fixed end and the connecting end of the winding rod. And the winding rod spirally retracts the drawstring.

The fixed end 52 of the cord is firstly fitted with the plug sleeve 53 It is mounted on the corresponding pivot plate 8 M269350 32, but it is not absolutely necessary to implement the joint 53, and the fixed end 52 can be directly mounted on the pivot plate 32. The fixed rope end ^ has a perforation 52 at the proximal end thereof, and the end of the drawstring 23 can pass through the perforation 521 to be tied and positioned. The rope guide mechanism 6 includes a screw seat M screwed to the outside of the rod 4, a rope guide member 62 fixed on the screw seat 61, and a ㈣ 63 fixed on the rope guide member 62. The screw seat 61 in this embodiment is a U-shaped plate-shaped body with internal threads, and when screwed to the outside of the screw 4, it is restricted by the «, so that when the screw 4 rotates, the screw 4 is blocked. The screw seat η is "turned" with the screw cymbal to thereby allow the screw seat 61 to be axially displaced between the first and second end portions 41 and 42 of the screw 4 due to the rotation of the screw 4. The deviating rope member 62 is fixed horizontally. It is knotted at the bottom of the screw seat 61, and extends an appropriate length from the screw seat ο towards the direction of the winding rod 5, and is parallel to the screw * and the winding rod $: square, and the rope guide 62 is near the winding rod 5- The end is provided with a guide hole 621 through which i and the pull rope 23 pass. The ring 63 is wrapped around the guide hole 621, and its setting function is to provide a smooth surface to make the pull ^ 23 可Passing through the guide hole 621 relatively smoothly, so the arrangement of the ring 圏 ^ is not necessary. In this embodiment, the rope guide 62 and the ring 63 are made of f material, but the metal is not used in practice. The material is limited, for example, the material-body injection molding integral rope guide mechanism 6 is also used. ^ This is to be further explained-the pull rope 23 is the first to wear the portion 52 from bottom to top After guide 621, it is then fixed to the two fixed ends of the winding rod 5 op! When the screw seat 61 is displaced relative to the screw 4 in the first and second ends of the four, the rope guide 62 will With the relative displacement, the M269350 guide hole ⑵㈣ the pull rope 23 is displaced between the _ end portion 51 of the winding rod 5. The W and Lian driving device 7 has a body that can pass through the screw rod 5 in a rotatable manner. A driving rod 71, a body rotatingly fixed to the driving rod 7 factory, a rotating wheel 72 ', and a 73 which can be operated to pull the rotating wheel 72 upward. The chain rope 73 drives the runner 72 to rotate 'make the driving rod' rotate the chain rope into a common structure of curtains' and the driving device :: the structure j achieves the driving rod 71 from the way of electric driving = driving. The purpose of driving the screw 4 and the winding rod 5 is not limited to the above-mentioned driving method during implementation. As a result, when the curtain sheet 22 is hanging to cover the window, the screw seat of the rope guide mechanism 6 61 is near the first end portion 4 of the screw 4 as shown in FIG. 2. The guide hole 621 of the rope guide 62 is near the fixed rope end of the winding rod ^, and the pull rope 24 is from bottom to bottom. The upper part passes through the holder 21, the bottom plate 3 of the pivot base 3, and the guide hole 621 of the rope guide 62, and then is fixed to the rope end 52 of the winding rod 5. At this time, if you want When the curtain sheet 22 is folded up, the chain 73 of the driving device 7 can be pulled to drive the screw 4 and the winding rod 5 to rotate, so that the guide hole 621 of the rope guide 62 is gradually moved from the fixed end 52 to the connection end. The part 51 and the reel 23 can be guided by the guide hole 621 of the rope guide 62, and as shown in FIG. 3, the fixed end 52 is gradually pulled to the connecting end 5 丨 and is rotated by the reel. 5 in a spiral The winding mode is used for winding and positioning, so that the pulling ropes 23 do not overlap each other on the outer peripheral surface of the winding rod 5. As long as the chain rope 73 of the driving device 7 is pulled in the opposite direction to drive the screw 4 and the winding rod 5 to rotate in the opposite direction, The guide hole 621 of the rope guide 62 can be reversely moved from the connection end 51 to the fixed rope end 52. Under normal circumstances, the pull rope 23 can be guided by the guide hole 621 of the rope guide 62 From the state of being wound on the roll rod $, it is sequentially lowered down through the guide hole 621. Since the drawstrings 23 do not overlap with each other during winding, there will be no jamming when hanging down in the past. In addition, it must be further explained that, since this embodiment uses a smooth cylindrical winding rod 5 to wind up the pull rope 23, when each curtain sheet 22 is blocked by an obstacle, it cannot be dropped down to form a pull rope. When the 23 cannot sag smoothly and the bee winds around the outside of the reel 5, even if the obstacle is removed momentarily, the drawstring 23 in a loose state is pulled by the curtain sheets 23 that are instantly lowered and pulled down, and the rope is pulled 23 During the rapid pull-down process, it can be relatively unobstructed by sliding on the smooth surface of the reel 5 And greatly reduce the probability that the drawstrings 23 are overlapped and wound on the outside of the reel 5, and even if they are overlapped, it is not easy to cause a jam phenomenon. Therefore, compared with the conventional winding of the drawstrings on the uneven thread surface, As far as the design is concerned, the design of this embodiment can effectively reduce the probability that the pull ropes overlap each other and jam on the surface of the external thread of the winding rod. As shown in FIG. 4, the second preferred embodiment of the new type retractor and the aforementioned implementation The difference is that the pivot base 3 further includes a support plate 33 extending upward from the bottom plate 31, and the support plate 33 is interposed between the two pivot plates 32 in parallel. Also in this embodiment, the screw 4 and The roll rod 5 is not made by plastic integral injection molding, but is separately formed by plastic injection molding and then joined, so that the screw 4 is inserted into the connection end portion 51 of the roll rod 5 with its first end portion 41, In addition, the connecting end portion 51 has a protruding ring 511 protruding radially around one end thereof. The protruding ring 511 has a ring groove 512 recessed in the outer peripheral surface thereof, and correspondingly rotatably corresponds to the% groove 5 12. Fit on the top edge of the support plate 3 3 M269350 of the pivot base 3, so that the screw 4 and the winding rod 5 The joint is supported. _The design of the segmented assembly of the screw 4 and the winding rod 5 can use different straight imitation winding rods 5 to match winding ropes of different lengths, so that the overall retractor has better versatility. The selection principle of the diameter of the winding rod 5 described above is that the longer the long draw rope 23 must be rolled up with the larger diameter winding rod 5. In addition, the fixed rope end 52 of the winding rod 5 further has a communication groove 522 extending inwardly from the end surface to the perforation 521 for the lateral insertion of the pull rope 23, and the width of the communication groove 522 is wider than the outer width. Narrow, and the width of the inner end is slightly narrower than the diameter of the perforation 522, so it can be convenient for the drawstring 23 to be knotted before the end, and then to extend from the communication groove 522 into the perforation 521 horizontally, so that the knotted part is affected The limitation is located inside the perforation 521. As shown in Figs. 5 and 6, the third preferred embodiment of the new type of retractor differs from the first embodiment described above in that the rope guide mechanism 6 is made of plastic injection molding and includes In addition to the screw seat 6 and the rope guide member M ′, a limit plate 64 parallel to the screw seat 61 is included, but the ring 63 in the foregoing m example is not provided. The limit plate 64 is formed to protrude beside the guide hole 621 of the rope guide 62 and is located at the side of the guide hole 621 # near the post 6 _, and the limit plate 64 is pivotally sleeved on the roll The rod 5 is external and is restricted by the rail frame 21 to prevent the rope guide 62 from being skewed and twisted due to the traction torque of the rope 23 passing through the guide hole 621. To sum up, the new retractor uses the relative axial displacement of the screw 4 screwed with each other and the screw seat 61 of the rope guide mechanism 6 to move the rope guide hole 621 of the rope guide Q gradually and smoothly from the smooth roll rod. 5 to wind up and release the drawstring 23, so that when the drawstring 23 encounters the curtain sheet 22 'being blocked during the release period, M269350 causes the drawstring 23 to be loosely wound around the outside of the roll rod 5, and it will be on the curtain sheet. 22 During the fast removal of the pull rope 23 while removing the obstruction, the pull rope 23 can slide on the smooth surface of the reel 5 unobstructed by the pull rope 23, which greatly reduces the probability of the rope being jammed on the reel 5 Therefore, it can indeed achieve the purpose of creation. However, the above are only the three preferred embodiments of the new model. When the scope of the new model cannot be limited by this, that is, the simple equivalent changes and modifications made according to the scope of the patent application and the description of the new model , Are still covered by the new patent.
