Description

Technical Field

[0001] This utility model relates to the technical field of Venetian blinds, and in particular to a Venetian blind ladder belt that prevents strangulation. Background Technology

[0002] Venetian blinds mainly consist of a top beam, a bottom beam, and slats connected between the top and bottom beams by a ladder rope. The top beam has a rotating mechanism. The ladder rope has two warp threads, with its upper and lower ends connected to the rotating mechanism and the bottom beam, respectively. Several weft threads are placed between the two warp threads of the ladder rope. The slats cross the weft threads. When one of the two warp threads of the ladder rope moves up and down relative to the other, the slats rotate, opening and closing the blinds. The lifting rope controls the raising and lowering of the slats. Lifting the rope raises the bottom beam, retracting the Venetian blinds; loosening the rope lowers the bottom beam, lowering the Venetian blinds. The ladder rope and lifting rope are independent components. Modern pull cords are not fixed to the ladder ropes; the lifting rope can be separated from the ladder rope. If there are children in the home, the lifting rope may be separated for play, potentially causing strangulation injuries to the children.

[0003] Chinese Patent Publication No. CN201367843Y, published on December 23, 2009, discloses a ladder-band structure for a Venetian blind, comprising: a rod extending laterally; one or more thin blades, 0.1-0.3 mm thick, arranged vertically at intervals at the bottom of the rod, each thin blade having at least two side sections with corresponding cord holes for a brake cord; a blade adjustment device, installed on the rod to adjust the angle of the thin blades; and at least two narrow, thin ladder-bands extending vertically downward from the bottom of the rod, each ladder-band including vertically spaced front and rear bands and horizontally connected between the front and rear bands with vertically spaced blade support portions, wherein the width of the front and rear bands is 8-15 mm and the thickness is 0.2-0.4 mm, and the positions of the front and rear bands are opposite to the cord holes of the thin blades. The drawback of this invention is that the lifting rope and ladder belt are installed separately, which can easily cause injury to children. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies where the lifting rope and ladder belt are separate, which can easily cause strangulation injuries. It provides a ladder belt for venetian blinds that integrates the lifting rope and ladder belt into one unit to prevent strangulation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A type of anti-snagging Venetian blind ladder belt includes a ladder belt body, connecting ropes, a protective sleeve, and a lifting rope. Connecting ropes are installed on both sides of the ladder belt body. One side of the connecting rope is connected to the ladder belt body, and the other side of the connecting rope is connected to the protective sleeve. The lifting rope is connected to the protective sleeve.

[0007] The ladder belt body is used to hold the slats. The ladder belt body drives the slats to rotate, and the rotation achieves light blocking. Protective sleeves are fixed to one side of the ladder belt body by connecting ropes on both sides, connecting the protective sleeves and the ladder belt body as one unit. After connection, a lifting rope is inserted into the protective sleeve. The presence of the lifting rope allows the Venetian blinds to be raised. The purpose of the protective sleeve is to protect the lifting rope. In case it is cut, it can also connect the lifting rope and the ladder belt into a whole, making it difficult to separate. This prevents the lifting rope from causing strangulation injury to people, thus achieving the purpose of assembling the lifting rope and the ladder belt into one unit.

[0008] Preferably, the ladder belt body includes pull ropes and ladder ropes. There are two pull ropes, and the two ends of each ladder rope are connected to the pull ropes on both sides. Several sets of ladder ropes are provided, with two ladder ropes in each set, and these sets are evenly distributed along the pull ropes. The ladder belt body consists of pull ropes and ladder ropes. The pull ropes on both sides are connected by ladder ropes. The pull ropes are used to control the tilt angle of the blades for shading. Several sets of ladder ropes are connected between the two pull ropes. Each set of ladder ropes holds one blade. The pull ropes on both sides are at different heights, changing the tilt angle of the ladder ropes and thus controlling the tilt angle of the blades. Each set of ladder ropes has two ladder ropes, placed on the upper and lower sides of the corresponding blade. The lower ladder rope controls the tilt of the blade, while the upper ladder rope assists in straightening it when it needs to be straightened. Both ends of the ladder ropes are connected to the pull ropes, which control the tilt of the ladder ropes. Blades are placed on each of the several sets of ladder ropes. This design allows for both upper and lower limit guidance of the blades to straighten them.

[0009] Preferably, the pull rope has several evenly distributed connecting ropes. One end of each connecting rope is connected to the pull rope, and the other end passes through the protective sleeve and connects to the pull rope. The pull rope has several evenly distributed connecting ropes, positioned on one side of the pull rope. These connecting ropes are used to connect to the fixing sleeve. One end of each connecting rope is connected to the pull rope, and the other end passes through the protective sleeve and connects back to the pull rope. By using these connecting ropes to install the protective sleeve on the connecting ropes on both sides, the connection between the pull rope and the protective sleeve prevents the protective sleeve from moving when the pull rope is pulled to control the blade angle. This design allows for better connection of the protective sleeve.

[0010] Preferably, a connecting rope is installed between every two sets of ladder ropes. The connecting ropes are distributed one between every two sets of lifting ropes. This distribution ensures even force distribution when pulling the lifting ropes to rise, better lifting the main body of the ladder belt, and also prevents the protective sleeve from separating from the pulling rope when lifting the protective sleeve. This design ensures even force distribution.

[0011] Preferably, the protective sleeve has a mesh structure and is tubular in shape. The lifting rope is placed inside the protective sleeve, with both its top and bottom ends positioned outside. The lifting rope, placed inside the protective sleeve, is pulled to raise the ladder belt body, thereby stacking the blades. The flexible mesh structure of the protective sleeve ensures that the lifting rope remains connected to the ladder belt body while also protecting it from damage. The flexible protective sleeve allows for better stacking of the lifting rope. The presence of the protective sleeve connects the ladder belt body and the lifting rope as a single unit without interference, thus protecting the lifting rope.

[0012] Preferably, the connecting rope and the pull rope are woven together as a single unit, and the ladder rope and the pull rope are also woven together as a single unit. The fact that the connecting rope and the pull rope are woven together as a single unit increases the connection strength between them, ensuring that the protective sleeve does not easily separate from the pull rope. Similarly, the ladder rope is woven together as a single unit with the pull rope, further increasing the connection strength between them. This design improves the overall strength of the ladder strap.

[0013] The beneficial effects of this utility model are: the lifting rope and the ladder belt are assembled into one piece, so as to limit and guide the blades to return to the correct position both above and below, which can better connect the protective sleeve, ensure uniform force distribution, protect the lifting rope, and improve the strength of the ladder belt.

[0015] In the diagram: 1. Ladder belt body; 2. Connecting rope; 3. Protective sleeve; 4. Lifting rope; 5. Pull rope; 6. Ladder rope. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 In the embodiment shown, a ladder belt for anti-snagging Venetian blinds includes a ladder belt body 1, a connecting rope 2, a protective sleeve 3, and a lifting rope 4. The connecting rope 2 is installed on both sides of the ladder belt body 1. One side of the connecting rope 2 is connected to the ladder belt body 1, and the other side of the connecting rope 2 is connected to the protective sleeve 3. The lifting rope 4 is connected to the protective sleeve 3.

[0018] The ladder belt body 1 includes pull ropes 5 and ladder ropes 6. There are two pull ropes 5. The two ends of the ladder ropes 6 are connected to the pull ropes 5 on both sides respectively. There are several groups of ladder ropes 6, with two ladder ropes in each group. The several groups of ladder ropes 6 are evenly distributed along the pull ropes 5.

[0019] The pull rope 5 is equipped with several evenly distributed connecting ropes 2. One end of the connecting rope 2 is connected to the pull rope 5, and the other end of the connecting rope 2 passes through the protective sleeve 3 and is connected to the pull rope 5. A connecting rope 2 is installed between every two sets of ladder ropes 6.

[0020] The protective sleeve 3 has a mesh structure and is tubular. The lifting rope 4 is placed inside the protective sleeve 3, with both its upper and lower ends on the outside of the protective sleeve 3. The connecting rope 2 and the pull rope 5 are woven together as one piece, and the ladder rope 6 and the pull rope 5 are woven together as one piece.

[0021] In use, pulling rope 5 raises one rope to the other, causing the ladder rope 6 to tilt. The tilting of the ladder rope 6 changes the angle of the blades between the two ladder ropes 6 in each group, thus providing shade. Because the protective sleeve 3 is made of mesh, pulling rope 5 does not affect the lifting rope 4.

[0022] When the lifting rope 4 is pulled up, the lower end of the lifting rope 4 rises, which drives the lower beam to rise. Since the lifting rope 4 is placed inside the protective sleeve, when the lifting rope 4 is pulled up, the protective sleeve 3 will rise and stack along the lifting rope 4. At the same time, the ladder belt body 1 and the protective sleeve 3 will be stacked together through the connecting rope 4.

[0023] Since the lifting rope 4 is connected to the pull rope of the ladder belt body 1 through the protective sleeve 3, it is not easy to separate the two, which can avoid strangulation and protect the lifting rope 4 located on the outside of the ladder belt body 1.
