Description

Technical Field

[0001] This application relates to the field of curtains, specifically to a type of curtain. Background Technology

[0002] Curtains are common items in people's lives, used for blocking light, protecting privacy, blocking wind and sun, and maintaining indoor temperature. Therefore, various types of curtains can be seen in both homes and offices, making them a necessity. However, curtains on the market often exhibit unevenness and warping after being rolled up and unrolled. This warping can cause light leakage, affecting the light-blocking effect and creating an unsightly appearance. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses a curtain. By setting a reinforcing structural layer on the surface of the curtain body, the anti-bending support of the reinforcing structural layer on the surface of the curtain body is utilized to avoid the unevenness problem of bending deformation when the curtain is rolled up and unfolded, thus ensuring the flatness of the curtain body surface.

[0004] The specific technical solution of this utility model is as follows:

[0005] A curtain includes: a roller, a support, a curtain body, and a horizontal rod. The roller is mounted on the support. A first side of the curtain body is connected to the roller, and an opposite second side is connected to the horizontal rod. Rotating the roller will roll up or unroll the curtain body. One side of the curtain body is provided with a reinforcing structural layer. The reinforcing structural layer includes a plurality of continuously connected reinforcing units. Each reinforcing unit includes an arc-shaped slat structure. The tops of the arc-shaped slat structures are spaced apart and connected to one side of the curtain body.

[0006] By incorporating a reinforcing structural layer on one side of the curtain, comprising several continuously connected reinforcing units, each including an arc-shaped slat structure, the bending strength of the curtain surface is enhanced. The arc-shaped slat structure possesses excellent straightness and bending resistance. The inclusion of this reinforcing structural layer along the extension direction of the arc-shaped slat structure further strengthens the resistance to bending deformation. Furthermore, the continuously connected arc-shaped slats can be rolled up in a direction orthogonal to the extension direction. By placing these arc-shaped slats on the curtain surface, the curtain's bending deformation resistance is enhanced while ensuring its rolling up and unrolling capability, thereby improving its flatness and effectively solving the problem of unevenness caused by bending deformation on the curtain surface after rolling up and unrolling in existing curtain systems.

[0007] Furthermore, the top extension directions of all the aforementioned arc-shaped strip structures are parallel to each other and consistent with the direction of the roll axis.

[0008] The parallel extension directions of the top of the curved slat structure help provide a more even supporting force, ensuring an effective connection between the reinforced structural layer and the curtain surface, and maintaining the flatness of the curtain surface. For curtains, this facilitates even rolling and storage, avoiding excessive bending in certain areas that can create creases.

[0009] Furthermore, the thicknesses of the arc-shaped strip structures are either completely the same, partially the same, or completely different.

[0010] Furthermore, any two adjacent reinforcing units are connected by an inverted arc-shaped strip structure.

[0011] The transition between any two adjacent reinforcing units is achieved through an inverted arc-shaped slat structure, maintaining the stability of the reinforcing units and ensuring their straightness and bending resistance. The continuity of the reinforcing units is achieved by alternating connections between the reinforcing units and the inverted arc-shaped slat structure, preventing swaying between units and maintaining the connection stability between the reinforcing units and the curtain surface. This prevents the reinforcing units from separating from the curtain surface due to swaying, thus maintaining the long-term stable flatness of the curtain surface under the action of the reinforcing units.

[0012] Furthermore, any adjacent arc-shaped strip structures and inverted arc-shaped strip structures are connected by straight plates.

[0013] Furthermore, any two adjacent reinforcing units are connected by a straight plate.

[0014] Setting a straight plate connection between any two adjacent reinforcing units helps to simplify the connection difficulty between adjacent reinforcing units.

[0015] Furthermore, the size of the reinforcing structural layer covers an area equal to the surface area of ​​the curtain.

[0016] The reinforced structure fully covers the curtain surface, providing more complete bending resistance and preventing localized deformation of areas where the reinforced structure is not covered.

[0017] Furthermore, the height of the reinforcing unit is 2mm to 100mm, and the thickness is 2mm to 50mm.

[0018] The height and thickness of the reinforced unit can determine the amount of material used and the size of the rolled-up curtain. Appropriate height and thickness can help save costs and avoid the curtain from being too large and taking up too much space after being rolled up.

[0019] Furthermore, the curtain also includes a protective film layer disposed on the side of the reinforcing structural layer away from the curtain body.

[0020] The protective film layer can both protect the reinforcing structural layer and make the curtains more beautiful.

[0021] Furthermore, the curtain also includes a curtain box and side frames. The curtain box has a cavity and an opening. The cavity is used to accommodate the roller, and the opening facilitates the rolling / unrolling of the curtain. The side frames are located on two sides of the curtain that are not in the direction of the roller axis. The side frames and the curtain are connected by guide rails. The two sides of the curtain are embedded in the guide rails, and the curtain slides in the guide rails to roll / unroll.

[0022] The curtain box has a cavity to accommodate and cover the roller, serving to decorate and beautify the curtains. It also has an opening for easy rolling and unrolling of the curtain. Side frames are located on two sides of the curtain that are not aligned with the roller axis. The side frames and curtain are connected by rails, allowing the curtain to slide within the rails for rolling and unrolling. The side frames effectively enhance the curtain's stability in windy conditions. Attached Figure Description

Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0037] Figure 1 This is a schematic diagram of the structure of a curtain according to an embodiment. A curtain 1 includes: a roller 10, a support 20, a curtain body 30, and a horizontal rod 40. The roller 10 is mounted on the support 20. A first side 301 of the curtain body 30 is connected to the roller 10, and an opposite second side 302 is connected to the horizontal rod 40. Rotating the roller 10 causes the curtain body 30 to roll up / unroll. The horizontal rod 40 is connected to the curtain body 30 and moves in unison with it. A reinforcing structural layer 50 is provided on one side of the curtain body 30. The reinforcing structural layer 50 includes a plurality of continuously connected reinforcing units 501. Each reinforcing unit 501 includes an arc-shaped strip structure 5011, with its top 5012 spaced apart and connected to one side of the curtain body 30.

[0038] To explain further, Figure 2 This is a schematic diagram of the shape of the reinforcing structure layer in an embodiment. Figure 3 This is a schematic diagram of the connection between the reinforcing structural layer and the curtain body in an embodiment. The reinforcing structural layer 50 includes a plurality of continuously connected reinforcing units 501. Figure 2 The portion within the dashed box), the reinforcing unit 501 includes an arc-shaped strip structure 5011, with the tops 5012 of the arc-shaped strip structure 5011 spaced apart, and the tops 5012 of the arc-shaped strip structure 5011 ( Figure 3 (As shown by the dashed line) is connected to the surface of the curtain.

[0039] Further explanation, such as Figure 2 As shown, the top 5012 of the arc-shaped strip structure 5011 mentioned in this utility model can refer to the top of the arc surface of each reinforcing unit 501, or it can refer to the connection between adjacent reinforcing units.

[0040] To further explain, by connecting a reinforcing structural layer 50 composed of continuously connected arc-shaped strip structures 5011 to the surface of the curtain body, the bending strength of the curtain body 30 of the window 1 can be enhanced. The arc-shaped strip structures 5011 have good straightness and bending resistance. By setting the reinforcing structural layer 50 as an arc-shaped strip structure 5011, the bending deformation strength along the extension direction of the arc-shaped strip structures 5011 is enhanced. Moreover, the continuously connected arc-shaped strip structures 5011 can also be rolled up in a direction orthogonal to the extension direction of the structure. By setting the arc-shaped strip structures 5011 on the surface of the curtain body 30, while ensuring that the curtain 1 can be rolled up, the bending deformation strength of the curtain 1 can be greatly enhanced, thereby improving the flatness of the curtain and effectively solving the problem of unevenness caused by bending deformation on the surface of the curtain body after the existing curtains are rolled up and unfolded.

[0041] To further explain, the crossbar 40 serves both decorative and counterweight functions. Its shape is not unique; the cross-section can be trapezoidal, rectangular, or circular. The crossbar 40 can be made of metals such as iron or stainless steel, or plastic, fiberglass, etc. End caps can be installed at both ends of the crossbar 40 for aesthetic purposes. These end caps can also include small steps to limit the movement of the rolled-up curtain surface and conceal gaps. The connection between the roller 10, the crossbar 40, and the curtain body 30 can be achieved through any method, such as adhesive bonding, pressure strip pressing, or snap fasteners.

[0042] Preferred, Figure 4 This is a schematic diagram showing the relationship between the top extension direction of the arc-shaped strip structure and the axis of the roll in this embodiment. The extension directions of the tops 5012 of all the arc-shaped strip structures 5011 are parallel to each other and consistent with the axis of the roll 100. Figure 4 (Direction indicated by the middle arrow).

[0043] To further explain, it can be understood that the tops 5012 of the arc-shaped strip structure 5011 can be distributed on two opposite surfaces of the reinforcing structure layer 50. Here, the parallelism of the tops 5012 of the arc-shaped strip structure 5011 can refer to the tops 5012 of the arc-shaped strip structure 5011 being parallel to each other within the same surface of the reinforcing structure layer, or it can refer to the tops 5012 of the arc-shaped strip structure 5011 being parallel to each other in space. In this case, the tops 5012 of the arc-shaped strip structure 5011 are not completely within the same surface of the reinforcing structure layer 50.

[0044] To further explain, the parallel extension directions of the top 5012 of the arc-shaped strip structure 5011 help provide a more uniform supporting force, ensuring an effective connection between the reinforced structure and the curtain surface, and maintaining the flatness of the curtain surface. For curtains, this facilitates even rolling and storage, avoiding excessive bending in certain areas that could cause creases.

[0045] Preferred, Figure 5 This is a schematic diagram of the shape of the arc-shaped strip structure in an embodiment. The thickness of the arc-shaped strip structure 5011 on the reinforcing structural layer is recorded as L. The thickness of each arc-shaped strip structure 5011 can have various combinations, such as... Figure 5 As shown in Figure a, the thickness L of the arc-shaped strip structure 5011 can be exactly the same; as Figure 5 As shown in Figure b, the thickness L of the arc-shaped strip structure 5011 can be partially the same; as Figure 5 As shown in Figure c, the thickness L of the arc-shaped strip structure 5011 can be completely different. By changing the thickness L of each arc-shaped strip structure, the bending strength of the reinforced structure can be varied.

[0046] Preferred, Figure 6 This is a schematic diagram of adjacent reinforcing units connected by an inverted arc-shaped strip structure in an embodiment. Any two adjacent reinforcing units 501 are connected by an inverted arc-shaped strip structure 5014. Figure 6 (The part inside the dashed box).

[0047] To further explain, the height and thickness of the arc-shaped strip structure on the reinforcing structural layer can be exactly the same as the height and thickness of the inverted arc-shaped strip structure; or the height and thickness of the arc-shaped strip structure on the reinforcing structural layer can be different from the height and thickness of the inverted arc-shaped strip structure. The definition of height and thickness here is the same as the definition of height and thickness of the reinforcing unit in the following text.

[0048] To further explain, the inverted arc-shaped strip structure 5014 achieves a transitional connection between any two adjacent reinforcing units 501, maintaining the stability of the reinforcing units and ensuring their straightness and bending resistance. The alternating connection between the reinforcing units and the inverted arc-shaped strip structure ensures the continuity of the reinforcing units, preventing swaying between them and maintaining the connection stability between the reinforcing units and the curtain surface. This prevents the reinforcing units from separating from the curtain surface due to swaying, thus maintaining the long-term stable flatness of the curtain surface under the action of the reinforcing units.

[0049] To further explain, the reinforcing structural layer can be formed by bending the sheet. The reinforcing structural layer is formed by bending the sheet in one direction along a position line and then bending it in the opposite direction along a position line a certain distance away. By continuously and alternately bending the sheet in two opposite directions at a certain interval, the reinforcing structural layer can be formed.

[0050] To further explain, the sheet material can be made of plastic materials such as polyethylene terephthalate (PET), polycarbonate (PC), and polymethyl methacrylate (PMMA). It can be made by continuously bending rolls of plastic material and cutting them to the size of the curtain surface, and then bonding them to the curtain surface with adhesive; or it can be made by continuously bending single sheets of plastic material and then bonding them to the curtain surface.

[0051] Preferred, Figure 7 The diagram illustrates the connection between the arc-shaped strip structure and the inverted arc-shaped strip structure in this embodiment via a straight plate. Any adjacent arc-shaped strip structure 5011 and inverted arc-shaped strip structure 5014 are connected by a straight plate 5013.

[0052] Preferred, Figure 8 The diagram illustrates the connection of adjacent reinforcing units via a straight plate in this embodiment. Any two adjacent reinforcing units 501 are connected via a straight plate 5013.

[0053] To further explain, setting a straight plate connection between any two adjacent reinforcing units helps to simplify the connection difficulty between adjacent reinforcing units.

[0054] Preferred, Figure 9 This is a schematic diagram illustrating the dimensions of the reinforcing structural layer and the surface dimensions of the curtain body in an embodiment. The length of the reinforcing structural layer 50 is denoted as G, and the width as K. The size of the reinforcing structural layer 50 is set to cover an area equal to the surface area of ​​the curtain body 30. More specifically, the length G of the reinforcing structural layer 50 can be set to be equal to the length of the surface of the curtain body 30, and the width K of the reinforcing structural layer 50 can be set to be equal to the width of the surface of the curtain body 30. To further explain, the reinforcing structural layer 50 fully covers the surface of the curtain body 30, providing more complete bending resistance and preventing localized deformation of areas where the reinforcing structural layer is not covered.

[0055] To further explain, when the edges of the curtain surface are relatively flat, the length G of the reinforcing structural layer can be less than the length of the curtain surface 30, and the width K of the reinforcing structural layer 50 can be less than the width of the curtain surface 30. This setting can reduce the weight of the curtain and achieve the flatness requirement of the curtain more easily.

[0056] Furthermore, Figure 10 This is a schematic diagram of the reinforcing unit dimensions in an embodiment. Let the height of the reinforcing unit be h, and the thickness be L. h can be set to 2 mm to 100 mm, and L to 2 mm to 50 mm. Figure 10 As shown in Figure a, when the reinforcing structural layer consists only of arc-shaped strip structures connected by straight plates, the height h and thickness L of the reinforcing unit are only the height and thickness of the arc-shaped strip structures; as shown in Figure a. Figure 10As shown in Figure b, when the reinforcing structure layer consists of arc-shaped strip structures and inverted arc-shaped strip structures connected by straight plates, the height h of the reinforcing unit refers to the distance between the top centers of adjacent arc-shaped strip structures, and the thickness L of the reinforcing unit refers to the total thickness of the arc-shaped strip structures, inverted arc-shaped strip structures, and the connecting straight plates.

[0057] To further explain, the height h and thickness L of the reinforcing unit 501 determine the amount of material used, the difficulty of molding, the bending deformation resistance of the molded reinforcing structural layer, and the roll-up size of the curtain. Therefore, under the premise of meeting the bending deformation resistance of the reinforcing structural layer, appropriate height and thickness are beneficial to saving costs and avoiding excessively large sizes and space occupation after the curtain is rolled up. When the height h and thickness L of the reinforcing unit are less than 2 mm, the difficulty of molding the reinforcing structural layer increases significantly, and the bending deformation resistance of the molded reinforcing structural layer is relatively low, which is not conducive to resisting the bending deformation after the curtain is rolled up. When the height h is greater than 100 mm and the thickness L is greater than 50 mm, the amount of material used and the roll-up size of the curtain increase significantly. The significant increase in material usage leads to excessive weight of the curtain, and the excessively large roll-up size is not conducive to the packaging, transportation, and installation of the curtain, and will also reduce the service life of the curtain.

[0058] Furthermore, 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.

[0059] In addition, the height h and thickness L of the reinforcing unit can also vary as follows: the height h changes along one direction while the thickness L remains constant; or the thickness L changes along one direction while the height h remains constant.

[0060] Preferred, Figure 11 As shown in another schematic diagram of the curtain structure in the embodiment, the curtain 1 also includes a protective film layer 60. The protective film layer 60 is disposed on the side of the reinforcing structure layer 50 away from the curtain body 30. The protective film layer 60 covers the reinforcing structure layer 50. When the curtain body 30 is rolled up or unrolled, the protective film layer 60 is also rolled up or unrolled together.

[0061] To further explain, the protective film layer 60 can be a flexible film or a flexible sheet. Its material can be one or more of the following transparent resin materials: polyacrylate, polyethylene terephthalate, fluorinated polymer, polyethylene terephthalate, polyxylene, polycarbonate, polyimide, etc. The protective film layer 60 can both protect the reinforcing structural layer 50 and make the winding or unwinding process of the curtain 30 more aesthetically pleasing.

[0062] Preferred, Figure 12As shown in another schematic diagram of the curtain structure in this embodiment, the curtain 1 also includes a curtain box 70 and side frame 80. The curtain box 70 is provided with a cavity for accommodating the roller 10 and covering the roller 10, thus serving to decorate and beautify the curtain. The curtain box 70 has an opening, so that the curtain can extend out of the opening when it is unfolded and can be rolled in through the opening when it is rolled up. The side frame 80 is located on two sides of the curtain 30 that are not in the direction of the rolling axis. The side frame 80 and the curtain 30 are connected by a guide rail 801. The two sides of the curtain 30 are embedded in the guide rail 801 and fixed, so that the two sides of the curtain 30 can slide in the guide rail 801, thereby realizing the rolling up and unfolding of the curtain.

[0063] In addition, the side frame 80 and guide rail 801 are designed so that the curtain body 30 is embedded in the guide rail 801 for fixed tension, which can effectively enhance the stability of the curtain when exposed to wind.

[0064] To further explain, a motor can also be installed inside the curtain box 70. The motor is connected to one end of the roller 10. The motor provides power for the entire curtain 1 to be rolled up and down. By controlling the motor to drive the roller 10 to rotate, the rolling up and down of the curtain can be controlled.

[0065] The curtain box 70 can be square, round, or polygonal in shape. Its decorative edge (cover) is generally only used in concealed or embedded products, and its shape can be "L", "T", or irregular. The various parts of the curtain box 70 can be connected by screws, clips, welding, etc. The roller 10 can use different involute structures to improve the height difference problem at the connection between the roller 10 and the curtain surface. The height of the involute can be changed according to the actual situation.

[0066] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
