Therefore, various window curtains can be seen in homes and offices, and window curtains have become a necessity in people's lives. The current market window curtains are rolled up and then unfolded, and the curtain surface often has bending deformation unevenness problems. These bending deformations can cause light leakage and affect the blocking effect, and also cause visual unattractiveness. CONTENT OF THE INVENTION

[0004] The specific technical scheme of the utility model is as follows:

The reinforcing unit is arranged in the form of an arc-shaped lath structure, the arc-shaped lath structure has good straightness and bending resistance, the bending deformation resistance in the extension direction of the arc-shaped lath structure is further enhanced, the continuously connected arc-shaped lath structure can also be rolled up in the direction perpendicular to the structure extension direction, the bending deformation resistance of the window curtain is greatly enhanced by arranging the arc-shaped lath structure on the surface of the window curtain, the flatness of the window curtain is improved, and the window curtain can also be rolled up. Therefore, the scheme can effectively solve the unevenness problem of bending deformation on the surface of the curtain body when the window curtain is rolled up and then unfolded.

DETAILED DESCRIPTION

[0035] In order for those skilled in the art to better understand the technical scheme of the present application, the present application will be further described in detail below in conjunction with specific embodiments.

[0036] Figure 1 A diagram showing the structure of a curtain of an embodiment. A curtain 1 comprises a reel 10, a support 20, a curtain body 30 and a crossbar 40. The reel 10 is installed on the support 20. The first edge 301 of the curtain body 30 is connected with the reel 10, and the opposite second edge 302 is connected with the crossbar 40. The reel 10 is rotated to drive the curtain body 30 to be rolled up / expanded. The crossbar 40 is connected with the curtain body 30 and moves in unison with the curtain body 30. A reinforcing structure layer 50 is arranged on one side of the curtain body 30. The reinforcing structure layer 50 comprises a plurality of reinforcing units 501 connected continuously. Each reinforcing unit 501 comprises a base layer 502 and a reinforcing layer 503. The base layer 502 and the reinforcing layer 503 are stacked to form a two-layer arc-shaped board-like structure 5011. The top 5012 of the arc-shaped board-like structure 5011 is spaced apart and connected with one side of the curtain body 30.

[0037] Further explanation and description, Figure 2 A diagram showing the shape of the reinforcing structure layer of an embodiment, Figure 3 A diagram showing the connection between the reinforcing structure layer and the curtain body of an embodiment. The reinforcing structure layer 50 comprises a plurality of reinforcing units 501 connected continuously. Figure 2The reinforcing unit 501 includes a base layer 502 and a reinforcing layer 503, the base layer 502 and the reinforcing layer 503 are laminated to form a two-layer arc-shaped strip structure 5011, the top 5012 of the arc-shaped strip structure 5011 is arranged in intervals, the top 5012 of the arc-shaped strip structure 5011 is connected to one side of the curtain body 30. Figure 3 The reinforcing unit 501 includes a base layer 502 and a reinforcing layer 503, the base layer 502 and the reinforcing layer 503 are laminated to form a two-layer arc-shaped strip structure 5011, the top 5012 of the arc-shaped strip structure 5011 is arranged in intervals, the top 5012 of the arc-shaped strip structure 5011 is connected to one side of the curtain body 30.

[0038] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0039] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0040] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0041] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0042] Further, the bending strength of the base layer 502 is less than or equal to the bending strength of the reinforcing layer 503.

[0043] Further explanation, the cross-sectional shape of the reinforcing layer 503 and the base layer 502 constitutes an arc-shaped strip structure is not limited to the drawings shown in this application, can be circular, multiple curve shape, etc., because the change of the cross-sectional shape of the reinforcing layer does not have a greater impact on the inherent mechanism of its promotion of the bending strength of the reinforcing structure layer.

[0044] Further explanation, the base layer 502 can be more than two layers of material of the multilayer composite layer, the reinforcing layer 503 can also be more than two layers of the multilayer material layer, thus constituting the reinforcing unit 501 can also be three, four, five, more than two layers of multilayer structure, here will not be listed; can be known that, to increase the bending strength of the reinforcing unit 501 composed of the base layer 502 and the reinforcing layer 503, more layers of reinforcing layer 503 can be set to adjust, and for different bending deformation of the product, the reinforcing structure layer 50 with corresponding bending resistance can be used to resist the bending deformation of the product, which can achieve better flatness of the product.

[0045] Further explanation, by setting the reinforcing structure layer 50 to the reinforcing unit 501 of the at least two layers of structure containing the base layer 502 and the reinforcing layer 503 connected continuously, the reinforcing layer 503 enhances the strength of the reinforcing unit 501, and the bending strength of the reinforcing structure layer 50 is improved, thereby overcoming the limitation of the bending strength of the single-layer arc-shaped strip structure of the reinforcing structure layer 50. The reinforcing unit 501 is set to the arc-shaped strip structure 5011, and the arc-shaped strip structure 5011 has good straightness and bending resistance, so that the bending deformation strength in the extension direction of the arc-shaped strip structure 5011 is further enhanced, and the continuously connected arc-shaped strip structure can also be wound in the direction perpendicular to the structure extension direction. By setting the arc-shaped strip structure on the surface of the curtain body, the bending deformation strength of the curtain is greatly enhanced, thereby improving the flatness of the curtain, and the curtain can also be wound, so that the problem of bending deformation and unevenness of the curtain when it is unfolded on the curtain surface after winding can be effectively solved.

[0046] Further explanation, the horizontal bar 40 has the functions of decoration and counterweight, and its shape is not unique, and the cross section can be trapezoidal, rectangular or circular. The material of the horizontal bar 40 can be selected from metal materials such as iron and stainless steel, and can also be selected from plastic and glass fiber. The two ends of the horizontal bar 40 can be provided with end covers for beautification. The end covers can be increased by a small step for limiting the curtain surface after winding and shielding the gap. The connection between the winding shaft 10, the horizontal bar 40 and the curtain body 30 can be any one of bonding, pressing, buckling and the like.

[0047] Preferably, Figure 4Figure 1 is a schematic view of the relationship between the extending direction of the top of the arc-shaped lath structure of the embodiment and the direction of the shaft axis of the roller. The extending direction of the top of all the arc-shaped lath structures is parallel to each other and consistent with the direction of the shaft axis of the roller (indicated by the arrow in the middle). Figure 4

[0048] Further explanation and description, the extending direction of the top of the arc-shaped lath structure is parallel to each other, which is beneficial to provide a more uniform support force, ensure the effective connection between the reinforcing structure layer 50 and the surface of the curtain body 30, and maintain the flatness of the surface of the curtain body 30. For the window curtain, it is beneficial to uniform winding and storage, and avoid excessive local bending to form creases.

[0049] Further explanation and description, here the top of the arc-shaped lath structure parallel to each other can refer to the top of the arc-shaped lath structure in the same plane of the reinforcing structure layer, or can refer to the top of the arc-shaped lath structure parallel to each other in space, at this time the top of the arc-shaped lath structure is not completely in the same plane of the reinforcing structure layer.

[0050] Preferably, Figure 5 Figure 2 is a schematic view of the connection between adjacent reinforcing units through the inverted arc-shaped lath structure of the embodiment. Any two adjacent reinforcing units 501 are connected through the inverted arc-shaped lath structure 5014.

[0051] Further explanation and description, the transition connection between any two adjacent reinforcing units is realized through the inverted arc-shaped lath structure 5014, the stability of the reinforcing unit is maintained, and the straightness and bending resistance of the reinforcing unit are guaranteed. The continuity of the reinforcing unit is realized by the interconnection between the reinforcing unit and the inverted arc-shaped lath structure, the shaking between the reinforcing units is avoided, the connection stability between the reinforcing unit and the surface of the curtain body is maintained, the separation between the reinforcing structure layer 50 and the surface of the curtain body 30 caused by the shaking of the reinforcing unit is avoided, and thus the long-term stable flatness of the surface of the curtain body 30 under the action of the reinforcing unit is maintained.

[0052] Preferably, Figure 6 Figure 3 is a schematic view of the connection between the arc-shaped lath structure and the inverted arc-shaped lath structure through the straight plate of the embodiment. Any adjacent arc-shaped lath structure 5011 and inverted arc-shaped lath structure 5014 are connected through the straight plate 5013.

[0053] Further explanation and description, the connection between the arc-shaped lath structure and the inverted arc-shaped lath structure through the straight plate can improve the stability of the entire reinforcing structure layer 50, and thus improve the flatness of the window curtain.

[0054] Further, Figure 7 Figure 4 is a schematic view of the connection between adjacent reinforcing units through the straight plate of the embodiment. Any two adjacent reinforcing units 501 are connected through the straight plate 5013.

[0055] ​Further, the two adjacent reinforcing units are connected by straight plates, which is beneficial to simplify the connection difficulty of the adjacent reinforcing units.

[0056] Further, the two adjacent reinforcing units 501 can also be connected by other structures with curved cross-sections, which will not be listed one by one. It can be understood that the reinforcing units 501 are not isolated from each other, but form a whole through the structural connection, thereby realizing the continuity of the reinforcing structure layer 50, avoiding the separation of the reinforcing units from the curtain body due to the shaking / twisting of the reinforcing units, thereby maintaining the long-term stable connection between the curtain body and the reinforcing units, and the flatness of the connection between the reinforcing structure and the curtain body.

[0057] Further, the single arc-shaped plate structure can be formed by bending the sheet material, that is, the sheet material is bent in one direction at a position line on the sheet material, and then the sheet material is bent in the opposite direction at a position line a certain distance away from the position line. In this way, the sheet material is continuously and alternately bent in two opposite directions at a certain interval to form the reinforcing structure layer.

[0058] Further, the sheet material can be made of PET, PC, PMMA or other plastic materials, which can be a roll of plastic material that is continuously bent and then cut into the size of the curtain surface, and then adhered to the curtain surface by adhesive; or it can be a single sheet of plastic material that is continuously bent and then adhered to the curtain surface.

[0059] Preferably, Figure 8 The size of the reinforcing structure layer of the embodiment and the surface size of the curtain body are shown in the schematic diagram, wherein the length of the reinforcing structure layer 50 is G, and the width of the reinforcing structure layer 50 is K.

[0060] The size of the reinforcing structure layer 50 is set to cover the surface area of the curtain body 30. Specifically, the length G of the reinforcing structure layer 50 is equal to the length of the surface of the curtain body 30, and the width K of the reinforcing structure layer 50 is equal to the width of the surface of the curtain body 30.

[0061] Further, the size of the reinforcing structure layer 50 fully covers the surface of the curtain body 30, which can provide more complete bending resistance to the surface of the curtain body 30, and avoid local deformation of the curtain body surface without the reinforcing structure layer.

[0062] Further, in the case where the edges of the curtain body 30 surface are relatively flat, the length G of the reinforcing structure layer 50 can be smaller than the length of the curtain body 30, and the width K of the reinforcing structure layer 50 can be smaller than the width of the surface of the curtain body 30. In this way, the weight of the curtain can be reduced, and the flatness requirement of the curtain can be more easily met.

[0063] Preferably, Figure 9The schematic diagram of the reinforcing unit size of the embodiment. The height of the reinforcing unit is h, and the thickness of the reinforcing unit is L. h can be set as 2mm-100mm, and L can be set as 2mm-50mm.

[0064] As shown in FIG. 1a, when the reinforcing structure layer is composed of only the arc-shaped strip structure or connected by straight plates, the height H of the reinforcing unit refers to the height of the arc-shaped strip structure, and the thickness L of the reinforcing unit refers to the thickness of the arc-shaped strip structure. Figure 9 As shown in FIG. 1b, when the reinforcing structure layer is composed of the arc-shaped strip structure and the inverted arc-shaped strip structure or connected by straight plates, the height H of the reinforcing unit refers to the distance between the top centers of the adjacent arc-shaped strip structures, and the thickness L of the reinforcing unit refers to the total thickness of the arc-shaped strip structure, the inverted arc-shaped strip structure and the connected straight plates. Figure 9 As shown in FIG. 1b, when the reinforcing structure layer is composed of the arc-shaped strip structure and the inverted arc-shaped strip structure or connected by straight plates, the height H of the reinforcing unit refers to the distance between the top centers of the adjacent arc-shaped strip structures, and the thickness L of the reinforcing unit refers to the total thickness of the arc-shaped strip structure, the inverted arc-shaped strip structure and the connected straight plates.

[0065] Further explanation, the height h of the reinforcing unit and the thickness L of the reinforcing unit can determine the amount of material, the difficulty of forming, the bending deformation strength of the formed reinforcing structure layer and the rolling size of the curtain, so under the premise of meeting the bending strength of the reinforcing structure layer, appropriate height and thickness are beneficial to save cost and avoid the size of the curtain after rolling being too large and occupying too much space. When the height h of the reinforcing unit is less than 2mm and the thickness L of the reinforcing unit is less than 2mm, the difficulty of forming the reinforcing structure layer is greatly increased, and the bending deformation strength of the formed reinforcing structure layer is smaller, which is not conducive to resisting the bending deformation of the curtain after rolling. When the height h of the reinforcing unit is greater than 100mm and the thickness L of the reinforcing unit is greater than 50mm, the amount of material and the rolling size of the curtain are greatly increased, the large amount of material leads to the weight of the curtain being too heavy, the large rolling size is not conducive to the packaging, transportation and installation of the curtain, and also reduces the service life of the curtain.

[0066] Further, the height h of the reinforcing unit can gradually decrease / increase along one direction, and the thickness L can gradually increase / decrease along one direction. In addition, the height h of the reinforcing unit and the thickness L can change as follows: the height h changes along one direction with a trend, and the thickness L is unchanged; the thickness L changes along one direction with a trend, and the height h is unchanged.

[0067] Preferably, Figure 10 The schematic diagram of the reinforcing layer of the embodiment arranged on the base layer. As shown in FIG. 2a, the reinforcing layer 503 can be arranged on one side of the base layer 502; as shown in FIG. 2b, the reinforcing layer 503 can be arranged on the opposite two sides of the base layer 502. Figure 10 The schematic diagram of the reinforcing layer of the embodiment arranged on the base layer. As shown in FIG. 2a, the reinforcing layer 503 can be arranged on one side of the base layer 502; as shown in FIG. 2b, the reinforcing layer 503 can be arranged on the opposite two sides of the base layer 502. Figure 10 The schematic diagram of the reinforcing layer of the embodiment arranged on the base layer. As shown in FIG. 2a, the reinforcing layer 503 can be arranged on one side of the base layer 502; as shown in FIG. 2b, the reinforcing layer 503 can be arranged on the opposite two sides of the base layer 502.

[0068] Preferably, the window curtain further comprises a protective film layer, which is arranged on the side of the reinforcing structure layer 50 away from the curtain body 30, and covers the reinforcing structure layer 50. When the curtain body is rolled up or unrolled, the protective film layer is also rolled up or unrolled.

[0069] Further explanation, the protective film layer can be a flexible film or a flexible sheet, and the material can be one or more of polyacrylate, polyethylene terephthalate, fluorinated polymer, polyethylene naphthalate, parylene, polycarbonate, polyimide, and other transparent resin materials. The protective film layer can not only protect the reinforcing structure layer 50, but also make the rolling or unrolling process of the curtain body more beautiful.

[0070] Figure 11 Another window curtain structure is shown in the embodiment. On the basis of the foregoing, the window curtain 1 further comprises a curtain box 70 and a side frame 80. The curtain box 70 is provided with a cavity for accommodating the roller 10, and covers the roller 10 to play a role of decorating and beautifying the window curtain. The curtain box 70 is provided with an opening, so that the curtain body can be extended out of the opening when unrolled, and can be rolled into the opening when rolled up. The side frame 80 is located on the two sides of the curtain body 30 which are not in the rolling direction of the roller 10. The side frame 80 and the curtain body 30 are connected through a guide rail 801, and the two side edges of the curtain body 30 are embedded in the guide rail 801 to be fixed. In this way, the two side edges of the curtain body 30 can slide in the guide rail 801, so as to realize the rolling and unrolling of the curtain body.

[0071] In addition, the setting of the side frame 80 and the guide rail 801, and the embedding of the curtain body 30 in the guide rail 801 to be fixed and tensioned, can effectively enhance the stability of the window curtain when encountering wind.

[0072] Further explanation, the motor can also be arranged in the curtain box 70, and the motor is connected with one end of the roller. The motor provides power for the rolling and unrolling of the entire window curtain. By controlling the motor to drive the roller to rotate, the rolling and unrolling of the window curtain can be controlled.

[0073] The shape of the curtain box 70 can be square, circular or polygonal, etc. The decorative edge (cover) is generally used for hidden or embedded products, and the shape can be "L" shape, "T" shape or special shape. The connection between the parts in the curtain box 70 can be achieved by using screws, buckles or welding.

[0074] In summary, the curtain of the utility model, through setting the reinforcing structure layer 50 into the reinforcing unit 501 of at least two layers of structure of the continuous connection of the base layer 502 and the reinforcing layer 503, the strength of the reinforcing layer 503 is enhanced to the reinforcing unit 501, the bending strength of the reinforcing structure layer 50 is improved, thereby overcoming the limitation of the bending strength improvement of the single-layer arc-shaped batten structure reinforcing structure layer. Further setting the reinforcing unit 501 shape is arc-shaped batten structure 5011, and the arc-shaped batten structure 5011 has good straightness and bending resistance, so that the bending deformation strength in the extension direction of the arc-shaped batten structure 5011 is further enhanced, and the continuously connected arc-shaped batten structure can also be wound in the direction orthogonal to the structure extension direction, by setting the arc-shaped batten structure on the curtain surface, the bending deformation strength of the curtain can be greatly enhanced, thereby improving the flatness of the curtain, and the curtain can also be wound, so that the unevenness problem of the curtain after being wound and unfolded on the curtain surface can be effectively solved.

[0075] The above is only the preferred embodiment of the utility model, and it should be pointed out that the above preferred embodiment should not be regarded as the limitation of the utility model, and the protection scope of the utility model should be limited by the range defined by the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the utility model, and these improvements and refinements should also be regarded as the protection scope of the utility model.
