Abstract
Description
Technical Field
[0001] This utility model relates to an improved Shangri-La curtain, belonging to the field of blackout curtain technology. Background Technology
[0002] Shangri-La blinds are decorative sunshades, typically composed of two sheer panels and several flexible blackout sheets connecting them. By adjusting the relative height of the two panels, the state of the flexible blackout sheets can be adjusted, bringing the panels closer together until completely closed, or moving them further apart until fully open. When fully closed, the blinds achieve optimal blackout and can be rolled up. During use, Shangri-La blinds ensure a degree of privacy while allowing some light to enter, maintaining excellent transparency and providing a pleasant user experience.
[0003] However, the sides of the Shangri-La blinds perpendicular to the direction of the blind fabric's extension, i.e., along the width of the blind fabric, are in an open state. In this partially closed state, the flat, narrow spaces formed by the two sheets of fabric and several flexible blackout panels easily accumulate mosquitoes and are difficult to clean. Under long-term use, a good user experience cannot be maintained. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, this invention proposes an improved Shangri-La blind that allows for easy maintenance of the blind material, prevents the accumulation of mosquitoes, and maintains the adjustable light-blocking effect of the Shangri-La blind.
[0005] This utility model relates to an improved Shangri-La curtain, comprising:
[0006] The upper rail is rotatable; the axial surface of the upper rail is provided with a first fixing area and a second fixing area.
[0007] Translucent fabric; in the extension direction, the front end of the translucent fabric is positioned in the first fixed area of the upper rail;
[0008] A flexible light-blocking sheet is provided with several sheets along the extension direction of the light-transmitting fabric; one end of the upper and lower ends of the flexible light-blocking sheet is fixed to the light-transmitting fabric as the first end, and the other end is not fixed to the light-transmitting fabric as the second end; in the flexible light-blocking sheet, the second end of one of the two adjacent sheets can be connected or overlapped with the first end of the other sheet.
[0009] The light-blocking adjustment rope extends in the same direction as the light-transmitting fabric, and several sets are provided along the direction parallel to the width of the light-transmitting fabric; the light-blocking adjustment rope is fixedly connected to the second end of the flexible light-blocking sheet; the front end of the light-blocking adjustment rope is set in the second fixed area of the upper rail.
[0010] The lower beam; the rear ends of the translucent fabric and the light-blocking adjustment rope are set on the lower beam.
[0011] The improved Shangri-La blind has both a light-transmitting state and a light-blocking state;
[0012] When the light is transmitted, the second ends of the light-blocking adjustment rope and the flexible light-blocking sheet are far away from the light-transmitting fabric. When the vertical distance between the second end of the flexible light-blocking sheet and the light-transmitting fabric reaches the maximum distance between the two, the improved Shangri-La blind is in the maximum light-transmitting state.
[0013] In the blackout state, both the blackout adjustment cord and the flexible blackout sheet are close to the light-transmitting fabric; when two adjacent flexible blackout sheets are joined or overlapped, the improved Shangri-La blind is in the maximum blackout state.
[0014] Butt joint refers to the edges of two adjacent flexible light-blocking sheets touching vertically at the same horizontal height along the width direction. Overlapping refers to a partial overlap of two adjacent flexible light-blocking sheets within a horizontal height range along the extension direction of the light-transmitting fabric, where the second end of one sheet overlaps the first end of the other sheet by a certain length. Compared to butt joint, overlapping provides better light blocking and avoids glare at certain angles caused by gaps at the edges. For overlapping, preferably, the overlap length is no more than 5% to 10% of the length of the flexible light-blocking sheet.
[0015] In some specific implementation schemes, the flexible light-blocking sheet is bonded and fixed to the light-transmitting fabric, and the fixed length is a first length; preferably, the first length is 15% to 25% of the length of the flexible light-blocking sheet.
[0016] In some specific implementation schemes, the flexible light-blocking sheet does not extend beyond the width of the translucent fabric; that is, the width of the flexible light-blocking sheet can be equal to or less than the width of the translucent fabric. Preferably, the width of the flexible light-blocking sheet is equal to the width of the translucent fabric. When the width of the flexible light-blocking sheet is less than the width of the translucent fabric, light-blocking treatment is required on both sides of the translucent fabric in the width direction to ensure the light-blocking effect. The light-blocking treatment can be by sewing on opaque fabric. The material of the opaque fabric can be the same as that of the flexible light-blocking sheet. If different opaque fabrics are used, it is best to ensure that the color and light-blocking performance of the opaque fabric are the same as those of the flexible light-blocking sheet. The light-blocking treatment can also be by pasting opaque material onto the translucent fabric.
[0017] In some specific implementation schemes, the light-blocking adjustment rope is bonded or sewn to the flexible light-blocking sheet, and the fixing length is the second length; preferably, the second length is 15% to 25% of the length of the flexible light-blocking sheet. The light-blocking adjustment ropes are arranged in an array along the width direction of the flexible light-blocking sheet at a certain interval, preferably 15% to 20% of the width of the flexible light-blocking sheet.
[0018] Preferably, the sewing fixation can be done by hand or by sewing machine. Considering the ease of operation and processing efficiency, adhesive fixation is the best, followed by mechanical sewing fixation, and then hand sewing fixation.
[0019] Compared with the prior art, the present invention has the following technical effects:
[0020] 1) Using a light-blocking adjustment cord instead of the inner layer of gauze, compared to double-layer gauze, it will not form a flat and narrow space that is closed at the top and bottom and open at the left and right with the flexible light-blocking sheet, thus avoiding the accumulation of mosquitoes in this space and making the curtain easy to clean.
[0021] 2) The improved Shangri-La blinds retain the adjustable light-blocking effect, and the light-blocking effect mainly comes from the flexible light-blocking sheet. Therefore, compared with double-layered gauze, the light-blocking effect remains unchanged in the fully blackout state.
[0022] 3) Using a light-blocking adjustment rope instead of the inner layer yarn reduces material costs compared to double-layer yarn;
[0023] 4) The light-transmitting fabric can be placed on either the light-facing side or the shaded side, making installation flexible. Attached Figure Description

[0029] The present invention will now be described in detail with reference to specific embodiments.
[0030] Example 1
[0031] like Figure 1 and Figure 2As shown, this embodiment relates to an improved Shangri-La blind, comprising: an upper track 100, a light-transmitting fabric 200, a flexible blackout sheet 300, a blackout adjustment cord 400, and a lower beam 500. In this embodiment, the dimensions parallel to the extension direction of the light-transmitting fabric are used as the length dimensions of the light-transmitting fabric, the flexible blackout sheet, and the blackout adjustment cord, and the dimensions parallel to the width direction of the light-transmitting fabric are used as the width dimensions of the light-transmitting fabric and the flexible blackout sheet.
[0032] The upper rail 100 is rotatably mounted, and its axial surface is provided with a first fixing area 101 and a second fixing area 102; a typical upper rail structure is as follows: Figures 2-4 The diagram shows a roller shutter tube with two square grooves; alternatively, a conventional roller shutter tube with only one square groove can be used, in which case the groove serves as both the first and second fixed areas. In the circumferential direction of the upper rail, the angle between the first fixed area 101 and the second fixed area 102 affects the length of the light-blocking adjustment rope 400, the length of the flexible light-blocking sheet 300, the spacing of the flexible light-blocking sheet 300, and the rotation angle required to adjust the upper rail 100 to achieve optimal light blocking and transmission effects. Other structural aspects of the roller shutter tube do not require improvement; they can be configured as needed, such as the presence, number, and location of reinforcing ribs within the roller shutter tube. The upper rail 100 can be driven by a combination of beaded ropes and beaded wheels as in existing technologies, or by a motor.
[0033] The following explanation uses an upper rail 100 with two square grooves as an example. One square groove serves as the first fixing area 101, and the other serves as the second fixing area 102. The two are arranged sequentially around the circumference of the upper rail, with an included angle preferably of 180°. At this angle, the flexible light-blocking sheet 300 has the longest length and the largest spacing, which is beneficial for the production of the improved Shangri-La blind.
[0034] In the extending direction of the light-transmitting fabric 200, the front end of the light-transmitting fabric 200 is positioned in the first fixing area 101 of the upper rail 100. This "setting" is a broad definition of fixing, which can be direct fixing, such as adhesive fixing, or indirect fixing, such as limiting fixing via a square groove. This limits the front end of the light-transmitting fabric 200 to the first fixing area 101, allowing the light-transmitting fabric 200 to gradually wrap around or detach from the surface of the upper rail 100 during rotation. For the limiting fixing, given that the light-transmitting fabric 200 is light-transmitting, thin, and has poor rigidity, to improve the limiting fixing effect, the front end of the light-transmitting fabric 200 can be fixed to a sheet material with better rigidity (such as woven packing straps) and then inserted into the first fixing area 101. The fixing method can be adhesive, Velcro, nail fixing, etc. This fixing length is a first length; preferably, the first length is 15% of the length of the flexible light-blocking sheet.
[0035] A flexible light-blocking sheet 300 is provided with several pieces along the extension direction of the light-transmitting fabric. In this embodiment, the upper end of the flexible light-blocking sheet 300 is fixed to the light-transmitting fabric 200 as the first end, and the lower end is fixedly connected to the light-blocking adjustment rope 400 as the second end. For two adjacent flexible light-blocking sheets 300, the second end of the front sheet and the first end of the rear sheet can overlap, with an overlap length of 8% of the length of the flexible light-blocking sheet, and the overlap length being the same as the width of the flexible light-blocking sheet. Preferably, the flexible light-blocking sheet 300 does not exceed the width of the light-transmitting fabric 200 in the width direction of the light-transmitting fabric; that is, the width of the flexible light-blocking sheet 300 can be equal to or less than the width of the light-transmitting fabric 200. In this embodiment, it is preferred that the width of the flexible light-blocking sheet 300 is equal to the width of the light-transmitting fabric 200.
[0036] In the extending direction of the translucent fabric 200, the front end of the light-blocking adjustment rope 400 is positioned in the second fixing area 102 of the upper rail 100. The front end of the light-blocking adjustment rope 400 can first be fixed to a fabric with good flexibility and poor rigidity, and then, similar to the translucent fabric 200, be fixedly connected to a sheet material with good rigidity, such as a woven packing strap, before being inserted into the first fixing area 101. Alternatively, the second fixing area 102 can be perforated, and the front end of the light-blocking adjustment rope 400 can be tied into the hole for fixation. Several groups of light-blocking adjustment ropes 400 are provided along the width direction of the translucent fabric, for example, four groups arranged in an array. The spacing between two adjacent groups of light-blocking adjustment ropes 400 is preferably 20% of the width of the flexible light-blocking sheet. The light-blocking adjustment rope is sewn and fixed to the flexible light-blocking sheet, with a fixing length of the second length, which is 20% of the length of the flexible light-blocking sheet. The number of light-blocking adjustment ropes in the same group can be one or more. By setting multiple parallel light-blocking adjustment ropes with small spacing (relative to different groups of light-blocking adjustment ropes) or nearly no spacing, it is easier to adjust the light blocking and light transmission. Flexible light-blocking sheets have advantages such as more stable stress and bending state, and are more sturdy and durable.
[0037] The rear ends of the translucent fabric 200 and the light-blocking adjustment rope 400 are mounted on the lower beam 500. This mounting is a broad definition of fixation, which can be direct fixation, such as adhesive bonding, or indirect fixation, such as fixation via a through-slot. For fixation via a through-slot, the lower beam 500 has a through-slot 501, through which the lower ends of the translucent fabric 200 and the light-blocking adjustment rope 400 are fixedly connected and pass through the through-slot 501, thus achieving fixation; the through-slot 501 is perpendicular to the radial direction of the upper rail. The fixed connection between the lower ends of the translucent fabric 200 and the light-blocking adjustment rope 400 can be direct or indirect. For indirect fixation, the lower end of the light-blocking adjustment rope 400 can be fixed to a fabric with good flexibility and poor rigidity, which is then fixedly connected to the light-blocking fabric 200. For direct fixation, a perforated hanging method can also be used.
[0038] For example, a longitudinal sectional view perpendicular to the axis of the upper rail. Figure 2 , Figure 3 and Figure 4 As shown, the improved Shangri-La blind described in this embodiment has both a light-transmitting state and a light-blocking state;
[0039] When the light is transmitted, the second ends of the light-blocking adjustment rope 400 and the flexible light-blocking sheet 300 are far away from the light-transmitting fabric 200. When the vertical distance between the second end of the flexible light-blocking sheet 300 and the light-transmitting fabric 200 reaches the maximum distance between them, the improved Shangri-La blind is in the maximum light-transmitting state.
[0040] In the blackout state, both the blackout adjustment cord 400 and the flexible blackout sheet 300 are close to the light-transmitting fabric; when the second end of one of the two adjacent flexible blackout sheets 300 overlaps with the first end of the other, the improved Shangri-La blind is in the maximum blackout state.
[0041] This embodiment describes the process of adjusting light transmission and shading by using the side of the translucent fabric as the light-facing side and the side of the shading adjustment rope as the back-facing side. Of course, in practical applications, the side of the shading adjustment rope can also be used as the light-facing side and the side of the translucent fabric as the back-facing side for adjusting light transmission and shading.
[0042] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
