[0004] Double-layer curtains are a common type of curtain, consisting of an inner and outer layer. They offer enhanced light-blocking, heat-insulating, and decorative effects. However, traditional double-layer curtains have several issues with the connection between the inner and outer layers. For example, the use of gluing or sewing makes them inconvenient to remove and replace. Furthermore, the adhesive used to connect double-layer curtains with glue weakens over time, causing the connection between the inner and outer layers to loosen, compromising the overall appearance of the curtains. Furthermore, the adhesive's stickiness can easily damage the curtains when they need to be separated for replacement or cleaning.

[0005] Another traditional connection method is to sew the inner and outer curtains together. However, this method is not convenient for disassembly, requiring the entire seam to be removed to separate the inner and outer curtains, which affects secondary use. In addition, the seams may affect the appearance of the curtains and introduce additional process complexity and production costs during the sewing process. [Utility Model Content]

[0007] In order to solve the problem in the prior art that the inner curtain and the outer curtain are connected by gluing or sewing in traditional double-layer curtains, which makes them inconvenient to disassemble and replace, the present application provides a double-layer curtain with a connector.

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] See also Figures 1 to 6 A double-layer curtain with a connecting piece includes an inner curtain 1, an outer curtain 2 and a connecting piece 3. The inner curtain 1 is provided with a plurality of first openings 4, and the outer curtain 2 is provided with a plurality of second openings 5 corresponding to the plurality of first openings 4. The corresponding first openings 4 and second openings 5 are used for the connecting piece 3 to pass through to connect the inner curtain 1 and the outer curtain 2.

[0032] The present invention discloses a double-layer curtain with a connector. By inserting the connector through a first opening and a second opening, the inner curtain and the outer curtain are connected. This structural arrangement facilitates installation and removal, making replacement and cleaning of the curtains more convenient and quicker to adapt to different seasons and decorative needs. Furthermore, the use of adhesives or sewing is avoided, reducing the complexity and production costs of the curtain manufacturing process.

[0033] Furthermore, as a preferred embodiment of the present invention but not a limitation, the distance between two vertically adjacent first openings 4 on the outer curtain 2 is S, and the distance between two vertically adjacent second openings 5 on the inner curtain 1 is L, wherein S>L.

[0034] In this embodiment, Figure 2 As shown, when the spacing distance S between the first openings is greater than the spacing distance L between the second openings, the outer curtain can protrude outward and hang down naturally. This method can maintain a good light-proof rate. The outer curtain can cover the gap between the first opening and the second opening to prevent light from overflowing.

[0035] Furthermore, as a preferred embodiment of the present invention but not limiting, each of the first openings 4 and each of the second openings 5 are respectively arranged along the length direction of the inner curtain 1 and the outer curtain 2, and the first openings 4 and the second openings 5 are for the connector 3 to pass through to form a plurality of unit blocks 8 on the outer curtain 2, and the unit blocks 8 are provided with fold portions 9 that make the unit blocks 8 protrude outward from the inner curtain 1.

[0036] In this embodiment, each unit block is connected by a connector and arranged vertically. This structure can enhance the layering and three-dimensional effect of the curtain, making the curtain more visually rich and diverse. At the same time, because each unit block is independent, the user can choose to open or close a specific unit block as needed to achieve different shading, ventilation, or decorative effects. Providing a folded portion on the unit block allows the unit block to protrude from the inner curtain layer, further enhancing the three-dimensional effect of the curtain. When the curtain is opened, the folded portion can give the unit block a certain curvature or fold, making the curtain look more natural and soft. In addition, the folded portion can also increase the elasticity and flexibility of the curtain, making the curtain more durable during use and less prone to deformation or damage.

[0037] Furthermore, as a preferred embodiment of this solution but not a limitation, it further includes a plurality of first openings 4 arranged along the width direction of the inner curtain 1 and a plurality of second openings 5 arranged along the width direction of the outer curtain 2 .

[0038] In this embodiment, the number of connection points between the inner and outer curtains can be increased, thereby improving the stability and firmness of the connection. When the curtains are pulled or blown by wind, the multiple connection points can better distribute the force, reducing the pressure on a single connection point and preventing the connection from loosening or damaging.

[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, the connector 3 includes a penetration portion 31 passing through the first opening 4 and the second opening 5 , and a limiting portion 32 for limiting the connector 3 from falling out of the first opening 4 and the second opening 5 .

[0040] In this embodiment, the design of the connecting portion allows the connector to easily pass through the first and second openings of the inner and outer curtains, thereby achieving a quick connection between the inner and outer curtains. This design avoids the complex procedures required by traditional connection methods, such as the use of glue or sutures, and improves the efficiency and convenience of the connection. The design of the stopper effectively prevents the connector from falling out of the first and second openings, thereby ensuring the stability and reliability of the connection between the inner and outer curtains. The stopper can be implemented in various ways, such as using an elastic material to allow it to return to its original shape and lock onto the edge of the opening after passing through, or by providing a barb, protrusion, or other structure on the stopper to allow it to lock onto the edge of the opening. Depending on the material and thickness of the curtains, the connecting portion can be selected in different shapes, such as round rod, I-beam, or oval, to enhance the stability and aesthetics of the connection. In addition, for special occasions or needs, such as outdoor use or curtains requiring wind and water resistance, the connector can be coated or treated with special coatings to improve its durability and functionality. In short, by rationally designing the structure and material of the connector, a variety of implementation methods can be achieved to meet the diverse needs of users.

[0041] Furthermore, as a preferred embodiment of the present invention but not a limitation, the connecting member 3 is provided with a through hole 7 for the Roman curtain cord 6 to pass through so as to limit the connecting member 3 from escaping from the first opening 4 and the second opening 5 .

[0042] In this embodiment, the through hole can be used to allow the pull cord to pass through to control the stretching, so that the pull cord can be raised and lowered in a straight line, and can also prevent the inner and outer curtains from detaching.

[0043] Furthermore, as a preferred embodiment of the present invention but not a limitation, the connecting member 3 is made of a flexible material. When the outer curtain 2 is connected to the inner curtain 1, the limiting portion 32 is folded and passed through the first opening 4 and the second opening 5 to allow the connecting portion 31 to pass through the first opening 4 and the second opening 5. At the same time, the limiting portion 32 is unfolded to limit the connecting member 3 from being separated from the first opening 4 and the second opening 5.

[0044] In this embodiment, the connector, made of flexible materials such as polyester, cotton, linen, velvet, or silk, exhibits excellent bending and folding properties, making connecting the inner and outer curtains more convenient and flexible. Furthermore, the user can easily fold the connector into a suitable shape as needed, allowing it to pass smoothly through the first and second openings without damaging or deforming the curtains. Flexible materials, as well as rigid materials such as plastic and metal sheets, can also be used. By setting an appropriate opening ratio and swinging the connector left and right, rigid materials can be inserted through the openings.

[0045] Furthermore, as a preferred embodiment of this solution but not a limitation, the length of the side of the limiting portion 32 away from the connecting portion 31 is smaller than the length of the side of the limiting portion 32 close to the connecting portion 31 .

[0046] In this embodiment, this structural arrangement facilitates the insertion of the connector through the first and second openings, improving connection convenience. The longer portion of the other side continues through the openings and eventually catches the edge of the other side. In this way, the stopper forms a stable buckle structure, firmly securing the connector to the curtain.

[0047] Furthermore, as a preferred embodiment of the present invention but not a limitation, the diameter of the through hole 7 is larger than the diameter of the Roman curtain cord 6 .

[0048] This embodiment allows the Roman curtain cord to easily pass through the through-hole, thereby securing and limiting the connector. Due to the large diameter of the through-hole, the Roman curtain cord encounters little resistance when passing through, allowing users to conveniently operate without the need for additional tools or equipment. Furthermore, the larger through-hole diameter reduces friction between the Roman curtain cord and the connector, thereby reducing the force required to pull the curtain. When the user needs to open or close the curtain, they only need to gently pull the Roman curtain cord to control the curtain without exerting excessive force. This not only improves the user experience but also extends the service life of the Roman curtain cord and connector.

[0049] Furthermore, as a preferred embodiment of the present invention but not a limitation, the connecting member 3 passes through the second opening 5 and the first opening 4 in sequence so that the limiting portion is located close to the inner curtain 1 .

[0050] In this embodiment, by locating the stopper near the inner curtain layer, the connector forms a hidden structure between the inner and outer curtain layers, maintaining the neatness and aesthetics of the curtains without detracting from their appearance. When the curtains are closed, the connector and stopper are concealed within the curtains, avoiding the visual inconvenience that can arise with traditional connection methods.

[0051] Furthermore, as a preferred embodiment of the present invention but not a limitation, the fold portion 9 includes a first fold 91 and a second fold 92 located below the unit block 8 , and a third fold 93 located above the unit block 8 .

[0052] This embodiment primarily utilizes a curtain that is rolled up using a roller system. Creases are formed during winding. The first and second creases can be formed by pre-pressing or by the natural rolling of the inner and outer curtain layers. The first crease allows the unit blocks to bulge outward when the curtain is unfolded, highlighting the curtain's texture and layering, adding visual richness. This not only makes the curtain more decoratively appealing, but also adds a unique sense of depth and artistry to the interior, enhancing the overall decorative effect. The third crease can be formed by pre-pressing or by the natural rolling of the inner and outer curtain layers, creating a richer texture and layering. The second crease creates a more natural and smooth concave-convex effect when the curtain is unfolded. This dual crease design not only enhances the curtain's decorative qualities but also creates a deeper and warmer indoor atmosphere by visually enhancing light and shadow effects. Thus, the second crease adds a further artistic element to the curtain, enhancing the indoor aesthetic and comfort.

[0053] In this embodiment 1, Figure 6 As shown, it includes multiple independent outer curtains 2, the second opening includes a top opening 100 provided at the top of the outer curtain 2, and a bottom opening 200 provided at the bottom of the outer curtain 2. The multiple independent outer curtains 2 are arranged in sequence from top to bottom on the inner curtain 1, and in two adjacent outer curtains 2, the bottom opening 200 of the outer curtain 2 located above corresponds to the bottom opening 200 of the outer curtain 2 located below. The connecting member 3 passes through the corresponding bottom opening 200, the top opening 100 and the second opening 5 of the inner curtain 1 in sequence to connect the inner curtain 1 and the outer curtain 2.

[0054] The working principle of this embodiment is as follows:

[0055] The present invention discloses a double-layer curtain with a connector. By inserting the connector through a first opening and a second opening, the inner curtain and the outer curtain are connected. This structural arrangement facilitates installation and removal, making replacement and cleaning of the curtains more convenient and quicker to adapt to different seasons and decorative needs. Furthermore, the use of adhesives or sewing is avoided, reducing the complexity and production costs of the curtain manufacturing process.
