[0003] The prior art CN106988665A discloses a rising louver that can block the lower half of the louver at the required height without affecting the sunlight entering from the upper half. It satisfies the need for lighting while also taking good care of the user's privacy. Although it can control the rotation of the louvers while pulling them up or down through the cooperation of the central sliding transmission gear and the rack and pinion, thus achieving the purpose of unilateral operation, the following technical problems still exist: the central sliding self-locking component is always connected to the central sliding mechanism. After the louver is flipped into place, it is necessary to overcome friction to continue to rise or fall, resulting in poor control feel.

[0016] Example 1 See Figures 1 to 10 A single-sided controllable, rise-type venetian blind insulated glass unit includes a window body 1, venetian blinds 2, a controller 3, and a lifting assembly 4. The venetian blinds 2 are located inside the window body 1. The window body 1 has a conventional structure, including a frame, inner glass, outer glass, etc. The specific structure will not be described in detail. The controller 3 is located on one side of the window body 1 and consists of an inner controller 31 and an outer controller 32. The inner controller 31 is located inside the window body 1, and the outer controller 32 is located outside the window body 1. The two controllers are magnetically attracted to each other for relative control; this is a conventional technology, and the specific structure and principle will not be described in detail. The frame on one side of the window body 1, facing the venetian blinds 2, has an extension edge 11 with opposing wire grooves 12. The lifting assembly 4 includes a first lifting rope 41, a second lifting rope 42, a first corner seat 43, and a second corner seat 44; The first corner bracket 43 is located at the corner of the window 1 above the controller 3, and the second corner bracket 44 is located at another corner of the window 1 on the same horizontal plane. The traction beam 21 is located on the upper part of the Venetian blind 2. One end of each of the two lifting ropes is fixed to the first corner bracket 43, and the other end goes down past the first movable pulley 311 on the inner controller 31, then goes up past the first fixed pulley 431 on the first corner bracket 43. The first lifting rope 41 goes down along the groove 12 and is fixed to one side of the traction beam 21. The second lifting rope 42 goes around the second fixed pulley 441 on the second corner bracket 44 and then turns downward to be fixed to the other side of the traction beam 21. It also includes a flipping assembly 5, which includes a flipping shaft 51, several flipping ladder ropes 52, several flipping seats 53, a rack 54, and a clutch mechanism 55; Half of the flip seat 53 is fixed inside the lower frame of the window 1, and the other half is set inside the traction beam 21. The flip shaft 51 is connected to the flip seat 53 inside the traction beam 21 in sequence. One end of the flip ladder rope 52 is fixed to the upper flip seat 53, and the other end is fixed to the lower flip seat 53. The slats of the Venetian blind 2 are laid on the flip ladder rope 52. How the flip shaft 51 and the flip seat 53 are connected, how the slats of the Venetian blind 2 are laid on the flip ladder rope 52, and how the flip ladder rope 52 operates are all conventional technologies, and will not be described in detail.
[0017] The rack 54 is mounted on the inner wall of one side groove 12. The flipping shaft 51 and the rack 54 are connected by a clutch mechanism 55. The gear shaft 554 meshes with the rack 54. The clutch mechanism 55 includes a mounting base 551, a gear shaft mounting bracket 552, a drive shaft 553, a gear shaft 554, a bearing 555, and a spring 556. Mounting base 551 is fixed to one side of the inner cavity of traction beam 21. Mounting base 551 has a first mounting cavity 5511 and a second mounting cavity 5512. Both the first mounting cavity 5511 and the second mounting cavity 5512 are cylindrical. The diameter of the first mounting cavity 5511 is smaller than the diameter of the second mounting cavity 5512. The second mounting cavity 5512 is provided with a first stop bar 5513 in the axial direction. A drive shaft 553 is disposed within a mounting base 551. One side of the drive shaft 553 is a mounting section 5531, and the other side is a connecting section 5532. The mounting section 5531 is disposed within a first mounting cavity 5511 and connected to a tilting shaft 51. The connecting section 5532 is disposed within a second mounting cavity 5512. A retaining ring 5533 is provided between the mounting section 5531 and the connecting section 5532. One side of the retaining ring 5533 is in contact with the inner wall of the second mounting cavity 5512. A second retaining strip 5534 is provided on the other side of the retaining ring 5533. A gap is provided between the second retaining strip 5534 and the connecting section 5532. The gear shaft mounting bracket 552 is fixed on the mounting base 551. The gear shaft mounting bracket 552 is provided with a mounting post 5521. The gear end 5541 of the gear shaft 554 is rotatably connected to the mounting post 5521. The shaft end 5542 of the gear shaft 554 is sleeved on the connecting section 5532 of the transmission shaft 553. The shaft end 5542 of the gear shaft 554 is sequentially sleeved with a bearing 555 and a spring 556. The bearing 555 is connected to the groove plate 13 of the two wire grooves 12. The spring 556 has raised limiting pieces 5561 at both ends. The included angle between the two limiting pieces 5561 is adapted to the maximum flip angle of the venetian blind 2 blades. When the spring 556 rotates, the limiting pieces 5561 at both ends will connect with the first stop bar 5513 or the second stop bar 5534.
[0018] In this embodiment, the mounting base 551 is provided with a plurality of insertion holes 5514, and the gear shaft mounting bracket 552 is provided with corresponding insertion strips 5522. The gear shaft mounting bracket 552 is fixed on the mounting base 551 by insertion and fitting.
[0019] It also includes a louver attitude-maintaining mechanism 6, which includes a third corner seat 61 and several pull ropes 62. One end of the pull rope 62 is connected and fixed to the flip seat 53 in the traction beam 21, and the other end passes through the through hole on the venetian blind 2, changes direction by passing around the transmission wheel in the bottom flip seat 53, changes direction again by passing around the pull rope pulley in the third corner seat 61, and then changes direction again by passing around the second moving pulley 63 on the inner controller 31, and finally is fixed on the third corner seat 61.
[0020] It also includes a magnetic attraction device 8, which consists of a first magnetic block located on the upper part of the traction beam and a corresponding second magnetic block located inside the upper frame of the window. The magnetic attraction device 8 can serve to fix the blinds 2 in place and prevent them from sliding down under the influence of gravity after reaching the top.
[0021] Implementation of the upward movement function of Venetian blinds: When the external controller 32 is moved downward, the internal controller 31 slides downward simultaneously, and the two lifting ropes also extend downward. The lifting ropes in the cable groove 12 are simultaneously lifted upward, which in turn drives the traction beam 21 to lift upward, thereby realizing the upward movement of the venetian blind 2.
[0022] Correspondingly, when the traction beam 21 is lifted upwards, it causes the pull rope 62 located in the louver attitude holding mechanism 6 to extend upwards, while the pull rope 62 inside the glass cavity shortens downwards to accommodate the upward movement of the louvered blind 2. The pull rope 62 can prevent the blades from shifting left or right during movement.
[0023] Similarly, by sliding the external controller 32 upwards, the Venetian blind 2 is lowered.
[0024] Venetian blinds can be flipped up and down. The external controller 32 slides up and down a short distance, and the internal controller 31 slides up and down synchronously, driving the two lifting ropes to move up and down, which in turn drives the traction beam 21 to move up and down accordingly. This in turn drives the gear shaft 554, which is inserted into the end of the traction beam 21, to move up and down. Because the gear shaft 554 is meshed with the rack 54, the gear shaft 554 rotates, which drives the flip shaft 51 to rotate at a certain angle, further driving the upper and lower flip seats 53 to rotate synchronously, and finally driving the flip ladder rope 52 to move up and down, thereby realizing the corresponding flipping action of the Venetian blind 2.
[0025] The function of clutch mechanism 55: When the gear shaft 554 meshes with the rack 54 and rotates clockwise, the gear shaft 554 rotates synchronously, and the spring 556 also rotates clockwise. After the limiting piece 5561 on the side of the spring 556 near the mounting base 5511 contacts the second stop bar 5534, when it continues to rotate, it pushes the transmission shaft 553 to rotate synchronously, which in turn drives the flipping shaft 51 to rotate clockwise synchronously. As the rotation continues, when the limiting piece 5561 of the spring 556 near the bearing 555 contacts the first stop bar 5513, the inner ring of the spring 556 will be expanded radially under the reverse force of the first stop bar 5513, thereby creating a gap between the shaft end 5542 and the spring 556. The rotation of the gear shaft 554 will not be able to drive the spring 556 to rotate, that is, the spring 556 will not push the transmission shaft 553 to rotate synchronously. In other words, the gear shaft 554 "spins freely" relative to the transmission shaft 553. In subsequent movements, the rotation of the gear shaft 554 will not have to overcome the reverse force from the flipping ladder rope 52 and the flipping seat 53, which greatly reduces the operating force and reduces working noise.
[0026] Example 2 See Figure 15 and 16The difference from Embodiment 1 is that this embodiment also includes an auxiliary counterweight mechanism 7, which includes an auxiliary counterweight block 71 and a counterweight connecting rope 72. The auxiliary counterweight block 71 is provided with a third movable pulley 73. One end of the counterweight connecting rope 72 is fixed to the inner controller 31, and the other end goes up past the first counterweight rope pulley in the first corner seat 43, then down past the second counterweight rope pulley in the second corner seat 44, and after passing the third movable pulley 73 on the auxiliary counterweight block, it is fixed to the second corner seat 44.
[0027] In this embodiment, an auxiliary counterweight mechanism 7 is designed to further reduce the force required for operation and greatly improve the feel of operation.
[0028] Example 3 See Figure 17 The difference from Embodiment 1 is that in Embodiment 1, one end of the first lifting rope 41 is fixed to the first corner seat 43, and the other end goes downwards past the first movable pulley 311 on the inner control unit 31, then upwards past the first fixed pulley 431 on the first corner seat 43. The first lifting rope 41 goes downwards along the groove 12 and passes through the traction beam 21, then upwards past the second fixed pulley 441 on the second corner seat 44, then turns to the right, past the first fixed pulley 431 on the first corner seat 43, past the first movable pulley 311 on the inner control unit 31, and finally upwards and is fixed to the first corner seat 43. This provides another lifting method.
