Description

Technical Field

[0001] This utility model belongs to the technical field of louvered insulated glass accessories, specifically involving the improvement of the flip ladder rope structure of louvered insulated glass. Background Technology

[0002] Built-in venetian blinds insulated glass systems, also known as insulated venetian blinds, are a new type of energy-saving product that installs venetian blinds inside insulated glass. The venetian blinds inside the insulated glass have the functions of raising, lowering, and rotating the blinds. The operation and control of the blinds are achieved through manual or electric control of the closing and lifting devices.

[0003] The flip ladder rope is a crucial component for enabling the Venetian blind to flip. The flipping principle of existing conventional flip ladder ropes is as follows: [See...] Figure 6 and Figure 7 The two main ropes b move relative to each other, causing the middle ladder rope c to tilt, which in turn causes the leaf a, which is placed on the ladder rope c, to tilt and flip, achieving the effect of closing and blocking light.

[0004] The aforementioned flip-up ladder rope has the following technical problems: After flipping, a relatively wide gap H will exist between the blades, and the angle of this gap H is small, resulting in poor light-blocking performance. Furthermore, because the angle of the gap H is small, the interior can still be seen through certain angles, failing to meet the user's need for privacy.

[0005] Therefore, how to further reduce the gap when the louvers are closed and increase the viewing angle of the gap so that it is not easy for people in adjacent buildings to see the privacy inside the louvers has become a technical problem that urgently needs to be solved. Utility Model Content

[0006] To address the above technical issues, this utility model provides a highly closed flipping ladder rope, which, after the blades flip, has a small gap between the blades, good light-blocking performance, and meets the user's need to protect privacy.

[0007] The technical solution of this utility model is: a high-closed flipping ladder rope, including a flipping rope body, the flipping rope body including two vertical main ropes, a number of ladder ropes evenly arranged between the two main ropes, and at least one long ladder rope between adjacent ladder ropes.

[0008] The long ladder rope is 5% to 15% longer than the ladder rope.

[0009] Preferably, the ladder ropes are arranged at equal or unequal intervals.

[0010] Preferably, each long ladder rope is also provided with at least one secondary long ladder rope adjacent to it.

[0011] Preferably, the ladder rope and the long ladder rope are made of flexible material.

[0012] Preferably, the elastic deformation range of the ladder rope and the long ladder rope is 1.2 to 1.4 times the normal length.

[0013] Preferably, the long ladder rope is 0.5 to 3 mm longer than the ladder rope.

[0014] Preferably, the ladder rope and the long ladder rope are short-fiber polyester rope or elastic nylon rope.

[0015] This invention breaks with the traditional model where the ladder ropes between the two main ropes are of uniform length, and innovatively incorporates both a ladder rope and a long ladder rope. The uniformly long ladder rope ensures the distance between the two main ropes; the long ladder rope alters the point of gravity after the blades flip, allowing the blades to tilt and sink deeper. The long ladder rope supports a larger flip angle for the blades, resulting in better light blocking and a wider viewing angle. This makes it difficult to see inside even if there is a significant height difference between adjacent buildings, achieving a high degree of closure.

[0016] The two types of ladder ropes are made of softer materials, which allows the two main ropes to move up and down more, further ensuring that the blades can close better when they flip. Attached Figure Description

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "vertical", "horizontal", "inner", "outer", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example 1

[0031] Figures 1 to 3 The middle is a high-closed flip ladder rope, see Figure 1 It is installed inside the glass cavity of window 1, and the Venetian blind 2 is driven to complete the flipping action by the flipping control device 4. The above are all existing technologies, and the specific structure and working principle will not be described in detail. In addition to the manual flipping structure shown in the figure, those skilled in the art can also use other flipping structures, such as electric flipping structures, to complete the flipping operation. Figure 1 This should not be construed as a limitation on the application scenarios of this utility model.

[0032] See Figures 1 to 3 The structure includes a flipping rope 3, which comprises two vertically placed main ropes 31. Several ladder ropes 32 are evenly arranged between the two main ropes 31, and a long ladder rope 33 is arranged between adjacent ladder ropes 32. It should be noted that the length of the ladder rope 32 is adapted to the diameter of the flipping roller in the flipping structure, which ensures the distance between the two main ropes 31. This is a conventional technology and will not be elaborated further in this case.

[0033] The long ladder rope 33 is 5% to 15% longer than the ladder rope 32. In this embodiment, the long ladder rope 33 is 2 mm longer than the ladder rope 32.

[0034] In this embodiment, each long ladder rope 33 is also provided with at least one secondary long ladder rope 34 adjacent to it. The two ends of the secondary long ladder rope 34 and the two ends of the adjacent long ladder rope 33 are located at the same place. The diameter of both the long ladder rope 33 and the secondary long ladder rope 34 is smaller than that of the ladder rope 32. The secondary long ladder rope 34 can achieve greater elastic deformation while ensuring the load-bearing strength.

[0035] In this embodiment, the ladder rope 32 and the long ladder rope 34 are made of flexible material, such as short-fiber polyester rope or elastic nylon rope. The elastic deformation range of the ladder rope 32 and the long ladder rope 34 is 1.2 to 1.4 times their normal length.

[0036] The principle behind the flip-ladder rope structure of this invention for achieving high blade closure is as follows: See Figure 2 and Figure 3 The spacing between the two main ropes 31 under normal conditions is controlled by the ladder rope 32. After the two main ropes 31 move up and down, compared with the existing flip ladder rope structure of the same size, when the main ropes 31 move up and down by the same distance, the longer ladder rope 32 is longer, and the blades 21 sink more deeply after tilting. Therefore, the visible gap h between the blades 21 is smaller. In this embodiment, the spacing between the blades 21 is less than 2 mm, achieving high closure.

[0037] The ladder rope is made of short-fiber polyester rope or elastic nylon rope, which is more flexible, allowing the two main ropes 31 to move up and down to a greater extent, and further enabling the blades 21 to close better when flipping.

[0038] The flip-up ladder rope provided by this utility model enables the louvered insulated glass to have good light-blocking performance and meets the user's need to protect privacy.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that, see... Figure 4 and Figure 5 In this embodiment, three long ladder ropes 33 are provided between adjacent ladder ropes 32. Providing more long ladder ropes 33 ensures a better closure effect.

[0041] The ladder ropes 32 are arranged at equal or unequal intervals. That is, the distance between adjacent ladder ropes 32 can be set in various forms according to the user's needs, such as equal intervals, increasing distance from top to bottom, or decreasing distance from top to bottom; when the intervals are equal, an equal number of long ladder ropes 33 can be set between adjacent ladder ropes 32; when the distance increases from top to bottom, the number of long ladder ropes 33 between adjacent ladder ropes 32 gradually increases, such as two at the top, three in the middle, etc.; similarly, a decreasing distance from top to bottom can be set.

[0042] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
