Description

Technical Field

[0001] The invention belongs to the technical field of hollow glass, and in particular relates to an improvement on a manually rising hollow louver glass window. Background Art

[0002] Built-in blinds and hollow glass are widely used in both high-rise and low-rise buildings (even bungalows). Among the existing technologies, the most widely used in the market is the descending blinds, that is, when the blinds set in the two layers of glass are fully opened, the blinds are stored at the top. When shading and shielding are required, the blinds are lowered. When light adjustment is required, the light adjustment is achieved by flipping the blades. However, when many bungalows, residents on both sides of the aisle, and residents on the lower floors use this type of blinds, the lower part of the window that needs to be shielded is often "open", and the environment inside the window is clear at a glance, which poses a privacy problem. In addition, the traditional descending type also has the problem of sunlight entering the room from the bottom. The ground reflected light after the sunlight enters the room causes glare discomfort to the people inside.

[0003] Therefore, those skilled in the art in the prior art have proposed electric and manual related technical measures to meet the needs of rising type Venetian blinds.

[0004] For example, the utility model patent technology of "Name: Rising Venetian Blinds, Authorization Announcement No.: CN 207092919 U" proposed a structural form of rising Venetian Blinds. However, after studying its specific technical measures, it was found that the operation was cumbersome and required manual locking; the structure was cumbersome and the structure of the middle sliding component was complex; the middle sliding component had many parts and heavy weight, so the manual operation force was also large. In addition, the case also uniquely proposed another flip device, namely the dimming frame, which cannot be applied in the field of insulating glass technology.

[0005] Therefore, how to improve the manual lifting structure to adapt it to the application in the blind hollow glass window, and further optimize its structure to reduce the operating force, has become a technical problem to be solved urgently in this field. Summary of the invention

[0022] like Figures 1 to 9 A manual blind upward hollow glass comprises a window 1 and a blind 2, wherein the blind 2 is arranged in the window 2, and the window 1 is a conventional structure, comprising a frame, inner glass, outer glass and other components, and the specific structure is not described in detail, see Fig. 9 The side frame of the window body 1 is provided with an extension edge 11 on the side facing the blind 2, and opposite wire grooves 11 are provided on the two extension edges 11, and also includes a blind lifting component 3 and a blind turning component 4.

[0023] See also Figure 3 , 4 The shutter lifting assembly 3 includes a lifting controller 31, a lifting rope 32, a traction beam 33, a first corner seat 34 and a second corner seat 35.

[0024] The lifting operator 31 is arranged on one side of the window body, and is divided into an inner lifting operator 311 and an outer lifting operator 312. The two are controlled by magnetic attraction. The specific principle and structure are not repeated here. The first corner seat 34 is arranged at the corner of the window body 1 above the lifting operator 31. See the figure. The second corner seat 35 is arranged at another corner of the window body 1 on the same horizontal plane. The traction beam 33 is arranged on the upper part of the venetian blind 2. One end of the lifting rope 32 is fixed on the first corner seat 34, and the other end is downwardly passed around the first movable pulley 3111 arranged on the inner lifting operator 311. In this embodiment, a counterweight block 3113 is arranged above the inner lifting operator 311, and a first movable pulley 3111 is arranged on the counterweight block 3113. Then it goes upward around the first fixed pulley 341 on the first corner seat 34, goes downward along the wire groove 111, turns and passes through the traction beam 33 and goes upward, goes around the second fixed pulley 351 on the second corner seat 35 and turns again, goes around the first fixed pulley 341 downward, then goes around the first movable pulley 3111 upward, and is finally fixed to the first corner seat 34.

[0025] See also Figure 3 , 5 The shutter flip assembly 4 includes a flip controller 41, 411 is an inner flip controller, 412 is an outer flip controller, a third corner seat 42, a flip pull rope 43, a plurality of flip ladder ropes 44, a flip shaft 45 and a plurality of flip seats 46.

[0026] The flip controller 41 is divided into an inner flip controller 411 and an outer flip controller 412, both of which are controlled by magnetic attraction. The specific principle and structure are not repeated here. One end of the flip ladder rope 44 is fixed to the traction beam 33 by a metal buckle, and the other end is wrapped around the rotator of the flip seat 46. The venetian blind 2 is mounted on the flip ladder rope 44. The flip seat 46 and the flip ladder rope 44 themselves are conventional technologies and are not repeated here.

[0027] However, the present invention innovatively fixes the flip seat 46 in the lower frame of the window 1, see Fig.11 The third corner seat 42 is arranged at the corner of the window 1 below the second corner seat 35, one end of the flip shaft 45 is connected to the first roller 421 arranged on the third corner seat 42, and the other end is connected to the rotator on the flip seat 46 in turn; this setting mode breaks the traditional concept of setting the flip seat 46 at the top, and its advantage is that the mass of the traction beam 33 is reduced in this case, because according to the technical practice in this field, the flip seat 46 must be set on the traction beam 33.

[0028] See also Fig.10 , 11One end of the flip rope 43 is fixed on the inner flip controller 411, and the other end is passed around the second roller 47 arranged on the second corner seat 35, then passed around the first roller 421 downward, and finally connected to the inner flip controller 411 upward; after many experiments by the inventor, it was verified that this structural form can reliably realize the flipping of the blades.

[0029] See also Figure 3 , 6 , and also includes a shutter posture maintaining mechanism 5, which includes a fourth corner seat 51 and a plurality of pull ropes 52. The fourth corner seat 51 is arranged at the corner of the window body 1 below the first corner seat 34. One end of the pull rope 52 is connected and fixed to the traction beam 33, and the other end is passed through the through hole on the shutter 2, changes direction after passing through the transmission wheel in the flip seat 46, and then changes direction after passing through the pull rope pulley 511 in the fourth lower corner seat 51, and then changes direction again after passing through the second movable pulley 53 below the inner lifting manipulator 311, and finally fixed on the fourth corner seat 51. As for the blind posture holding structure 5, the present invention breaks the traditional blind system that uses ropes made of inelastic materials, and can use ropes with certain elasticity to complete the technical task. The advantage of having certain elasticity is that it can maintain a certain tension, ensuring that the top of the pull rope 52 is fixedly connected to the bottom surface of the traction beam 33, and the bottom of the pull rope 52 is connected to the second movable pulley 53 at the bottom of the inner lifting controller 311 through the pulley change direction. In this case, the length of the pull rope 52 is relatively fixed, and it forms a complete pulling rope system with the lifting rope system. The lower end of the bottom beam of the blind is always in a straight state between the rope winder 36, thereby realizing the constraint of the blind sheet in the lateral direction of the window.

[0030] A traction beam plug 331 is provided on both sides of the traction beam 33. The traction beam plug 331 includes a plug body 3311, a cover plate 3313 and a bearing 3314. One end of the plug body 3311 is embedded in the inner cavity of the traction beam 33, and the other end is provided with a fixing buckle 3312, which fastens the cover plate 3313 and the plug body 3311. The bearing 3314 is installed between the cover plate 3313 and the plug body 3311. In this embodiment, the inner ring of the bearing 3314 is embedded in the fixing buckle 3312 to realize the bearing 3 The installation of 314, the bearing 3314 is connected to the slot plate 112 of the line slot 111 on both sides, and the track between the slot plates 112 forms a constraint to prevent the traction beam 33 from shaking when the traction beam plug 331 drives the traction beam 33 to move up and down, thereby improving the operation stability, and there is sliding friction between the bearing 3314 and the slot plate 112, and the operation is smooth. Through holes that are interconnected are provided in the middle of the plug body 3311 and the cover plate 3313, and are connected to the inner cavity of the traction beam 33.

[0031] The cover plate 3313 is provided with roller seats 3315 on the upper and lower sides, and the roller seats 3315 are provided with lifting rope rollers 3316; the lifting rope 32 passes through the wire groove 111 of the side frame, overlaps the lifting rope rollers 3316, passes through the plug cover plate 3313, the through hole in the middle of the plug body 3311, and then passes through the inner cavity of the traction beam 33 and out from the other end. Such a structure greatly reduces the friction between the lifting rope 32 and the traction beam 33.

[0032] In this embodiment, a magnetic device 6 is also included, a magnetic block A61 is provided on the upper part of the traction beam 33, and a magnetic block B62 is correspondingly provided in the upper frame of the window body 1. The magnetic device 6 can play a fixing role to prevent the blind 2 from sliding down under the action of gravity after reaching the top.

[0033] How to realize the upward function of the blinds: By operating the outer lifting inner controller 312, the inner lifting inner controller 311 slides downward synchronously, the lifting rope 32 extends downward, and the lifting rope 32 in the wire groove 111 is lifted upward synchronously, thereby driving the upward lifting beam 3, so as to realize the upward movement of the blind 2.

[0034] Correspondingly, when the upward beam 3 is lifted, the pull rope 52 located in the shutter posture holding mechanism 5 is driven to extend upward, and the pull rope 52 in the glass cavity is shortened downward to adapt to the upward movement of the shutter 2. The pull rope 52 can prevent the blades from shifting left and right during the movement.

[0035] Similarly, the inner controller 312 slides upwards corresponding to the outer lifting operation to achieve the lowering of the blind 2.

[0036] How to implement the flip function of the blinds: The outer flip controller 412 is controlled to slide up and down in a short distance, and the inner flip controller 411 is synchronously slid up and down, driving the flip pull rope 43 to move, thereby driving the first roller 412 to rotate at a certain angle, further driving the flip shaft 45 to rotate, thereby driving the rotator in the flip seat 46 to rotate synchronously, and finally driving the flip ladder rope 44 to move up and down, thereby realizing the corresponding flipping action of the blind 2.

[0037] There is another optimized embodiment of the present invention, see Figure 12 to Figure 14 , this embodiment also includes an auxiliary counterweight mechanism 7, the auxiliary counterweight mechanism 7 includes an auxiliary counterweight block 71 and a counterweight connecting rope 72; An auxiliary counterweight block 71 is set on the upper inner part of the frame on one side of the flip manipulator 41, and a third movable pulley 711 is set on the auxiliary counterweight block 71. One end of the counterweight connecting rope 72 is fixed to the inner lifting manipulator 311, and the other end is upwardly passed through the first counterweight rope pulley 73 in the first transmission seat 34, and downwardly passed through the second counterweight rope pulley 74 in the second transmission seat 35. After passing the third movable pulley 711 on the auxiliary counterweight block 71, it is moved upward and fixed to the second corner seat 35.

[0038] The additional auxiliary weight mechanism 7 can reduce the force during manipulation, greatly improving the upward operation feel during manipulation.

[0039] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present invention, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present invention.
