Description

Technical Field

[0001] This invention relates to the field of curtains, and more specifically to a method for replacing Venetian blind slats. Background Technology

[0002] Venetian blinds are a type of window that originated in China. In ancient Chinese architecture, there were straight-lattice windows, which were used in various dynasties from the Warring States period to the Han Dynasty. The vertical lattice windows are called straight-lattice windows, and the horizontal lattice windows are called horizontal-lattice windows. Horizontal-lattice windows are a primitive style of venetian blinds, or you could say that they are the original state of venetian blinds. Venetian blinds are now widely used in many aspects of life.

[0003] Venetian blinds are generally made of opaque aluminum slats. However, regardless of the material, the slats may bend or break during use. Under current technology, when slats are damaged and need to be replaced, all slats must be removed and replaced with new ones. Finally, the slats must be threaded and reinstalled. The entire replacement process is very complicated. Therefore, people usually choose to send the blinds back to the manufacturer for repair or have the manufacturer send someone to repair them, which is time-consuming and costly.

[0004] Currently, there are attempts to reduce the difficulty of replacing the louvers. For example, the published patent CN113819536A involves a horizontal louver that replaces the louver blades by adding a series of structural components such as a fixing ball, an arc-shaped fixing block, a spring, and a groove to the device. However, there are too many components involved, which limits the application range of the louver. The replacement steps are also very complicated and impractical. Summary of the Invention

[0005] In view of the problems raised in the background art, the present invention provides a method for replacing louver blades to solve the problems, and the present invention will be further described below.

[0006] A method for replacing louver blades includes the following steps:

[0007] Cut off the damaged target blade and place the spare blade on the ladder rope at the original target blade position;

[0008] First, slide the wire into the blade through the wire guide groove;

[0009] Place the two connecting parts of the connector on the upper and lower sides of the blade, respectively;

[0010] The connector is fastened so that the T-shaped inlet slot and the through slot form a closed opening, and the pull wire is placed in the closed opening to realize the replacement of the blade.

[0011] Optionally, the connector fastening step specifically includes: sliding the pull wire into the T-shaped inlet groove of the connector; the connector's clip engaging with the clip groove, so that the T-shaped inlet groove and the through groove form a closed opening.

[0012] Optionally, the fastening step of the connector specifically includes: the clip of the connector passes through the slot and then fastens with the slot on the other side, thus closing the wire passage into a closed opening.

[0013] Furthermore, the method for replacing louver blades also includes, after fastening the connectors, pulling the edge wire into the wire groove.

[0014] Beneficial effects: Compared with the prior art, the present invention provides the replacement blades and connectors as accessories to consumers. Consumers can replace the damaged blades themselves in daily life. When replacing the blades, there is no need to disassemble the venetian blinds. Simply cut the target blade, align the blade directly with the pull line and install it so that the pull line slides into the blade. Then, directly fasten the connector to the blade, enclose the pull line in the blade, and clamp and fasten the spare blade and connector. The steps are simple and easy to operate, which is acceptable to consumers. Attached Figure Description

[0022] The following detailed description of a specific embodiment of the present invention is based on the accompanying drawings.

[0023] A method for replacing louver blades involves clamping spare blades 2 onto the louver using a connector 1.

[0024] It should be noted that the insertion method of the guy wires for suspending the blades is a conventional technique, generally consisting of three vertically parallel guy wires. The outer two wires are located outside the blade, and the middle one passes through the blade. The three parallel guy wires are connected by a horizontal guy wire, which supports the blade. (See attached diagram.) Figure 1-2 This embodiment does not provide a detailed explanation of the principles involved. The wires mentioned below refer to the middle wires that pass through the blades.

[0025] Reference Appendix Figure 3-4 In one embodiment 1, the connector 1 includes two movable parts that are movably connected. One movable part is provided with a locking head 101, and the other movable part is provided with a locking groove 102. The spare blade 2 used for replacement is structurally different from the original blade. Specifically, the original blade is only provided with a wire hole, and the wire hole is located in the middle of the blade, while the blade 2 to be replaced is provided with an open wire groove 201, which extends to the edge of the blade.

[0026] The length of the connector 1 is longer than the width of the blade. After the blade 2 is fastened, it is tightly clamped by the two connectors, and the two side edges are restricted between the connection point and the fastening point of the connector. In addition, in this embodiment, the connector 1 is provided with a T-shaped cable inlet groove 103, which extends to the outside of the connector.

[0027] Based on the structural features of this connector, a method for replacing louver blades is provided, comprising the following steps:

[0028] Cut off the damaged target blade and place the spare blade on the ladder rope at the original target blade position;

[0029] First, slide the pull wire 3 into the blade 4 through the wire groove 201 of the blade;

[0030] Place the two connecting parts of connector 1 on the upper and lower sides of blade 4 respectively;

[0031] Slide the pull wire 3 into the T-shaped inlet groove 103 of the connector 1;

[0032] The connector's clip 101 engages with the slot 102, forming a closed opening between the T-shaped inlet slot 103 and the through slot 201.

[0033] In this embodiment, the target blades can be replaced without disassembling the louvers, and the blades can be fully wrapped and clamped, providing strong clamping force.

[0034] Reference Appendix Figure 5-6In another embodiment 2, the connector 1 includes two movable parts that are movably connected. One movable part is provided with a locking head 101, and the other movable part is provided with a locking groove 102. The spare blade 2 for replacement is also provided with an open wire passage groove 201, which extends to the edge of the blade. The length of the connector 1 is shorter than the width of the blade. The blade 2 is provided with a locking opening 202, which corresponds to the locking groove 102 of the connector.

[0035] Based on the structural features of this connector, a method for replacing louver blades is provided, comprising the following steps:

[0036] Cut off the damaged target blade and place the spare blade on the ladder rope at the original target blade position;

[0037] First, slide the pull wire 3 into the blade 4 through the wire groove 201 of the blade;

[0038] Place the two connecting parts of connector 1 on the upper and lower sides of blade 4 respectively;

[0039] The connector's clip (not shown) passes through the clip 202 and engages with the clip 102 on the other side, sealing the wire groove 201 into a closed opening.

[0040] In this embodiment, the connector and the blade are mechanically connected to form a whole. Unlike the above embodiment, which relies solely on the friction between the connector and the blade to maintain the whole, this embodiment is in an absolutely static state. Furthermore, in this embodiment, the connector only clamps the blade portion, and there is no need to laterally oscillate the pull wire during installation, making blade replacement more convenient.

[0041] Furthermore, in Embodiment 1, the connector 1 has a wire-pressing groove 104 at the edge of the connection and the fastening point of the movable part, and in Embodiment 2, the connector 1 has a wire-pressing groove 104 at the connection of the movable part. Furthermore, after the replacement method is described, the method further includes: pulling the edge pull wire into the wire-pressing groove 104. The wire-pressing groove 104 is designed to limit the pull wire and prevent it from sliding on the edge of the connector or blade.

[0042] This invention provides the replacement blades and connectors as accessories to consumers, allowing them to easily replace damaged blades in their daily lives. Replacement does not require disassembling the louvers; simply cut the target blade and clamp it to the connector. The process is simple, easy to operate, and acceptable to consumers.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
