Description

Technical Field

[0001] The utility model relates to a curtain, in particular to a structure of a shielding material used for the curtain. Background Art

[0002] Common vertical curtains currently include an upper beam and a curtain body. The curtain body is operably mounted on the upper beam and includes multiple shielding elements. When the user wishes to adjust the intensity of incoming light from outside or to protect personal privacy from being directly viewed from outside, the user can further control the expansion, contraction, or deflection of the curtain body by pulling a cord and / or operating a lever.

[0003] In early designs, single curtains typically used a single fabric. However, this design presented several problems. First, single-fabric curtains appeared monotonous and lacked aesthetic appeal, which did not meet consumer demand for diverse curtain designs. Second, due to the limitations of a single fabric, the shade level could not be adjusted based on user needs.

[0004] Recently, some new designs have emerged in which a single shelter, while made of the same fabric material, is formed using different weave patterns in different areas. While this design allows for slight variations in the texture of the shelter, it also comes with a more complex manufacturing process, leading to increased production costs. Furthermore, the variability in appearance achieved through different weave patterns is still limited, leaving room for improvement. Utility Model Content

[0070] See also Figures 1 to 3 , showing a three-dimensional view, a three-dimensional exploded view and a front view of an embodiment of the curtain of the utility model. Figures 1 to 3 In the illustrated embodiment, the curtain 1 can be installed in an opening of a building, such as a window, a door, an arch, and the like. The curtain 1 includes an upper beam 10 , a control mechanism 20 , and a curtain body 30 .

[0071] In this embodiment, the upper beam 10 is made of a rigid material (such as plastic, metal, alloy or composite material, etc.), and the upper beam 10 is generally a hollow rectangular parallelepiped, and defines a receiving space for part of the control mechanism 20 to be disposed therein. The control mechanism 20 includes Figure 1 The operating rod 22 is exposed on the upper beam 10, and Figure 2 The transmission shaft 24, pulley 26, and connecting assembly 28, etc., disposed within the accommodation space of the upper beam 10, are conventionally known and will not be described in detail here. The curtain body 30 is suspended below the upper beam 10 via the control mechanism 20, which controls the transmission shaft 24, pulley 26, and connecting assembly 28 disposed within the accommodation space of the upper beam 10. The user can control the curtain body 30 via the control mechanism 20 to deploy, retract, or rotate it, depending on the usage scenario.

[0072] See also Figures 1 to 5 The curtain body 30 includes a plurality of shielding members 40, the number of which can be increased or decreased according to the width of the curtain 1 and the difference in design requirements. Figure 1 When in the open light-transmitting state, each shielding object 40 is roughly U-shaped and is arranged closely together. Preferably, each shielding object 40 can remain independent and can be separated by force to allow users to pass through freely.

[0073] Please refer to Figures 6 to 8 , Figures 6 to 8 Schematic diagram of different viewing angles of an embodiment of the shielding device of the utility model after being flattened, wherein: Figure 6 is the rear view, Figure 7 For top view, Figure 8is a front view. In this embodiment, the shielding member 40 includes a first shielding member 42, a second shielding member 44, and a third shielding member 46. The first shielding member 42 is divided into a first region 424 and a second region 426 along a first centerline 422 along its length. The second shielding member 44 is disposed in the first region 424 of the first shielding member 42. The first and second shielding members 42, 44 are ultrasonically welded together in a stacked manner along their length. The third shielding member 46 is disposed in the second region 426 of the first shielding member 42. The first and third shielding members 42, 46 are ultrasonically welded together in a stacked manner along their length.

[0074] In this embodiment, the material of the first shielding member 42 is different from the material of the second shielding member 44, and the material of the first shielding member 42 is also different from the material of the third shielding member 46, but the material of the second shielding member 44 and the third shielding member 46 are the same. In other embodiments, the materials of the first shielding member 42, the second shielding member 44, and the third shielding member 46 may all be different or all be the same. In other embodiments, the material of the first shielding member 42 and the second shielding member 44 is the same, but the material of the first shielding member 42 and the third shielding member 46 are different.

[0075] However, regardless of the materials used for the first shielding member 42, the second shielding member 44, and the third shielding member 46, in order to ultrasonically weld the second shielding member 44 and the third shielding member 46 to the first shielding member 42, in some embodiments, the first shielding member 42 must comprise at least a thermoplastic material, while the second shielding member 44 and the third shielding member 46 do not necessarily comprise a thermoplastic material. In other embodiments, the second shielding member 44 and the third shielding member 46 must comprise at least a thermoplastic material, while the first shielding member 42 does not necessarily comprise a thermoplastic material. In other embodiments, the first shielding member 42, the second shielding member 44, and the third shielding member 46 all comprise a thermoplastic material. The property of thermoplastic materials that melt and then solidify during the ultrasonic welding process allows the different shielding members to be welded together to form a shield.

[0076] The aforementioned thermoplastic material can be at least one of polyester (PET), nylon, polyethylene (PE), polypropylene (PP), polycarbonate (PC), polystyrene (PS), polyvinyl chloride (PVC), polylactic acid (PLA), ethylene vinyl acetate (EVA), polyurethane (PU), and polyamide (PA). The thermoplastic material can be present in the form of a fiber, i.e., as one or all of the materials constituting the shielding element, or in the form of a surface coating.

[0077] like Figures 6 to 8In the embodiment, the second shielding member 44 and the third shielding member 46 are all made of thermoplastic materials. For example, the material of the second shielding member and the third shielding member is a non-woven fabric made of polyester fiber, or a non-woven fabric made of a combination of polyester fiber and nylon fiber. The first shielding member 42 does not contain thermoplastic materials, but is made of natural fibers such as cotton, linen and other materials. At this time, when the first shielding member 42, the second shielding member 44 and the third shielding member 46 of the shield 40 are ultrasonically welded, the second shielding member 44 and the third shielding member 46 will be partially melted and then adhered to the first shielding member 42, forming welding areas P1 and P2. Figure 6 and Figure 8 As shown, since the second shielding member 44 and the third shielding member 46 in this embodiment are made of thermoplastic material, and the first shielding member 42 does not include thermoplastic material, after ultrasonic welding, only the welding areas P1 and P2 (such as Figure 8 The front view shows the welding point 68), but the rear view does not have it (as shown in FIG. Figure 6 (as shown in the rear view). Conversely, if the second shielding member 44 and the third shielding member 46 are swapped with the first shielding member 42, after ultrasonic welding, the welded area is visible only from the rear view, not from the front view. It will be appreciated that if all shielding members are made of thermoplastic material, the welded area will be visible from both the front and rear views after ultrasonic welding.

[0078] In other embodiments, the second and third shielding members may also be made of composite materials composed of thermoplastic materials and other materials based on the user's aesthetic preferences, interior design, and light transmittance. Other materials may include yarn, cloth, natural fibers, artificial fibers, synthetic fibers, plastics, wood, and metal materials, and may be made into the fabric of the shielding members through forming processes such as weaving, knitting, braiding, or non-woven fabrics.

[0079] Please refer to Figures 6 to 8 In this embodiment, the second shielding member 44 has a second centerline 442 along its length. The second centerline 442 divides the second shielding member 44 into a second inner region 444 and a second outer region 446. The second inner region 444 is adjacent to the first shielding member 42, while the second outer region 446 is distal to the first shielding member 42. The ultrasonic welding area P1 between the first and second shielding members 42 and 44 is located within the second inner region 444 of the second shielding member 44. The third shielding member 46 has a third centerline 462 along its length. The third centerline 462 divides the third shielding member 46 into a third inner region 464 and a third outer region 466. The third inner region 464 is adjacent to the first shielding member 42, while the third outer region 466 is distal to the first shielding member 42. The ultrasonic welding area P2 between the first and third shielding members 42 and 46 is located within the third inner region 464 of the third shielding member 46.

[0080] See also Figures 8 to 10 To avoid the risk of the shielding pieces being easily torn from the edges of the welding areas P1 and P2 due to the user pulling after ultrasonic welding, in this embodiment, the distribution of the welding points 68 in the ultrasonic welding area P1 between the first shielding piece 42 and the second shielding piece 44, and the distribution of the welding points 68 in the ultrasonic welding area P2 between the first shielding piece 42 and the third shielding piece 46 are both arranged in a repeated and non-continuous pattern. For example, Figure 9 The distribution of the welding points 70 in the welding area P3 is point-shaped. Figure 10 The weld points 72 in welding area P4 are shown as short horizontal lines. By distributing the weld points 68, 70, and 72 in ultrasonic welding areas P1, P2, P3, and P4 in a non-contiguous manner, the shield 40 can achieve better tear resistance. Furthermore, to ensure the stability and reliability of ultrasonic welding, the ultrasonic welding equipment should contact the shield with a thermoplastic material or coating to ensure that each weld point 68, 70, and 72 can reliably melt the thermoplastic material or coating.

[0081] See also Figures 11 to 13 , Figures 11 to 13 Schematic diagram of another embodiment of the shield of the utility model after being flattened at different viewing angles, wherein: Figure 11 is the rear view, Figure 12 For top view, Figure 13 It is a front view. In this embodiment, the second shielding member 64 includes a second base 64B and a second surface coating 64L, and the third shielding member 66 includes a third base 66B and a third surface coating 66L. The second surface coating 64L and the third surface coating 66L include thermoplastic materials, and such thermoplastic materials include at least one of polyester (PET), nylon (Nylon), polyethylene (PE), polypropylene (PP), polycarbonate (PC), polystyrene (PS), polyvinyl chloride (PVC), polylactic acid (PLA), ethylene / vinyl acetate (EVA), polyurethane (PU) and polyamide (PA). Thermoplastic materials are non-sticky and solid at room temperature, and will only melt and become sticky under the high temperature of ultrasonic welding. Depending on the process requirements, the surface coating can be applied to the entire base of the shielding member, or only to a partial area for use in ultrasonic welding. As Figures 11 to 13 As shown, the second surface coating 64L and the third surface coating 66L are only applied to the area adjacent to the first shielding member 62. Therefore, when the first shielding member 62, the second shielding member 64, and the third shielding member 66 of the shield 60 are ultrasonically welded, the surface coatings 64L and 66L of the second shielding member 64 and the third shielding member 66 are partially melted and then adhered to the first shielding member 62 to form a welded area.

[0082] Figures 11 to 13 The advantage of the embodiment is that, since the thermoplastic material used to weld the shield is coated on the surface of the base, any fabric that can be attached to the surface of the thermoplastic material can be selected as the base, thereby increasing the diversity of base fabric selection. In addition, since the surface coating containing the thermoplastic material is not sticky at room temperature, the first shielding member 62, the second shielding member 64 and the third shielding member 66 can be stored separately before the shield 60 is ultrasonically welded, which makes inventory management and material transportation more advantageous. In addition, in this embodiment, when the first shielding member 62, the second base 64B and the third base 66B are all made of opaque materials, the weld area formed after ultrasonic welding is transparent regardless of the front view (such as Figure 13 as shown) or rear view (as shown Figure 11 Therefore, the front and rear appearances of the shield 60 are consistent, and there are fewer restrictions on manufacturing and application.

[0083] At Figures 6 to 13 In the embodiment described above, the second and third shielding members must comprise at least a thermoplastic material. In other embodiments, when the first shielding member must comprise at least a thermoplastic material, the first shielding member may be made entirely of thermoplastic material. Alternatively, a composite material composed of a thermoplastic material and another material may be used. Furthermore, a fabric having a thermoplastic surface coating applied to the surface of the thermoplastic material and / or the other material may be used.

[0084] See also Figures 14 to 16 , Figures 14 to 16 Schematic diagram of another embodiment of the shield of the utility model after being flattened at different viewing angles, wherein: Figure 14 is the rear view, Figure 15 For top view, Figure 16 In this embodiment, the shielding member 40A includes a first shielding member 42 , a second shielding member 44 , a third shielding member 46 , a fourth shielding member 48 and a fifth shielding member 50 .

[0085] The fourth shielding member 48 and the second shielding member 44 are both disposed in the first region 424 of the first shielding member 42, and the first region 424 of the first shielding member 42 is sandwiched between the second shielding member 44 and the fourth shielding member 48. The second shielding member 44 and the fourth shielding member 48 are ultrasonically welded to the first shielding member 42 in a stacked manner along the length direction.

[0086] The fifth shielding member 50 and the third shielding member 46 are both disposed in the second region 426 of the first shielding member 42, and the second region 426 of the first shielding member 42 is sandwiched between the third shielding member 46 and the fifth shielding member 50. The third shielding member 46 and the fifth shielding member 50 are ultrasonically welded to the first shielding member 42 in a stacked manner along the length direction.

[0087] In this embodiment, the fourth shielding member 48 has the same width, length, and material as the second shielding member 44, and the fifth shielding member 50 has the same width, length, and material as the third shielding member 46. In other embodiments, the width, length, and material can be adjusted based on user needs, achieving a specific aesthetic or light-blocking effect by combining different widths, lengths, and materials.

[0088] However, regardless of the width, length, and material of the first shielding member 42, the second shielding member 44, the third shielding member 46, the fourth shielding member 48, and the fifth shielding member 50, in order to allow the second shielding member 44, the third shielding member 46, the fourth shielding member 48, and the fifth shielding member 50 to be ultrasonically welded to the first shielding member 42, the first shielding member 42 must at least be made of a thermoplastic material, while the second shielding member 44, the third shielding member 46, the fourth shielding member 48, and the fifth shielding member 50 do not necessarily need to be made of a thermoplastic material. In other embodiments, the second shielding member 44, the third shielding member 46, the fourth shielding member 48, and the fifth shielding member 50 must be made of a thermoplastic material, while the first shielding member does not necessarily need to be made of a thermoplastic material.

[0089] like Figures 14 to 16 In the embodiment, the first shielding member 42 is made entirely of a thermoplastic material, such as a non-woven polyester fabric. The second, third, fourth, and fifth shielding members 44, 46, 48, and 50 are not made of thermoplastic materials, but are instead made of natural fibers such as cotton and linen. When the first, second, third, fourth, and fifth shielding members 42, 44, 46, 48, and 50 of the shield 40A are ultrasonically welded, the first shielding member 42 is partially melted and then bonded to the second, third, fourth, and fifth shielding members 44, 46, 48, and 50, respectively, forming welded areas P5, P6, P7, and P8.

[0090] The advantage of this embodiment is that since only the first shielding member 42 includes a thermoplastic material, while the second shielding member 44, the third shielding member 46, the fourth shielding member 48, and the fifth shielding member 50 do not include a thermoplastic material, during ultrasonic welding, only the first shielding member 42 is melted to form the welding areas P5, P6, P7, and P8. At the same time, the other second shielding members 44, the third shielding member 46, the fourth shielding member 48, and the fifth shielding member 50 will block the areas of the first shielding member 42 that are melted and deformed, thereby making the appearance of the shield 40A more beautiful.

[0091] Preferably, the second shielding member 44 and the fourth shielding member 48 do not overlap with the first shielding member 42, as shown in FIG. Figure 15 The connection area P9 can also be coated with a thermoplastic surface coating and then joined by ultrasonic welding, or by gluing, sewing, etc. Similarly, between the third shielding member 46 and the fifth shielding member 50, as shown in FIG. Figure 15 The connecting area P10 can also be coated with a thermoplastic material and then joined by ultrasonic welding, gluing, sewing, etc. This double-layered shielding member provides a better light-shielding effect for the shield 40A and also improves the overall stiffness of the shield 40A.

[0092] It's worth noting that the curtain body of a single window curtain is not limited to using only a single type of shielding material, such as only shielding material 40, only shielding material 60, or only shielding material 40A. In some embodiments, the curtain body of a single window curtain may utilize a combination of shielding material 40, shielding material 60, and shielding material 40A. For example, the curtain body of a single window curtain may alternate between shielding material 40 and shielding material 40A, creating a repetitive and interlaced design. In other embodiments, the curtain body of a single window curtain may utilize shielding material 40A on only two sides, with multiple shielding materials 40 positioned between two shielding materials 40A. This can enhance light blocking on both sides of the curtain body and reduce light leakage from both sides.

[0093] In summary, the shielding members 40, 40A, 60 of the present invention utilize ultrasonic welding to allow the shielding members 40, 40A, 60 to be combined with shielding members of different materials to create a specific visual style and meet specific usage requirements, while also reducing production costs and improving production efficiency.

[0094] The specific embodiments presented in the detailed description of the implementation methods are only used to facilitate the explanation of the technical content of the present invention, and are not intended to narrowly limit the present invention to the above embodiments. Various changes and implementations made without departing from the spirit of the present invention and the scope of the following patent applications are all within the scope of the present invention.
