Description

Technical Field

[0001] The utility model relates to a retractable shading strip. Background Art

[0002] Existing curtain designs, without dedicated blackout strips on both sides, can be inadequate at blocking light. This is because there's often a gap between the curtain and the window frame or wall. This can allow light to penetrate these gaps during daytime or nighttime situations where complete light blockage is required (such as during sleep), compromising the shading effect. To improve this, blackout strips can be added to both sides of the curtain to block the gap between the curtain and the window frame, thereby enhancing light-blocking performance.

[0003] There are some curtains currently available on the market that are equipped with blackout strips, but these strips are often manufactured to standard lengths, which means they cannot perfectly adapt to all window sizes. Because the heights of windows in users' homes vary, the fixed blackout strips may be too long or too short, resulting in the need to cut them during installation to match specific window sizes. Such cutting not only requires additional time and tools, but also, if not done properly, may affect the functionality and aesthetics of the blackout strips. Therefore, the applicant designed a retractable blackout strip. Utility Model Content

[0030] (Example 1)

[0031] See Figure 1-2 The retractable shade strips of this embodiment are installed on both sides of the curtain to block the gap between the curtain and the wall. They include side rails and end caps 1. The side rails are recessed, with one side open, into which the curtain's edges are positioned. The side rails include outer rails 2 and inner rails 3. The outer rails 2 are located at either end of the side rails. The outer rails 2 are spaced apart from the inner rails 3, and the inner rails 3 are inserted into the outer rails 2, allowing them to slide relative to each other along their lengths. Two end caps 1 are installed, one at the outer ends of the two outer rails 2 at the ends of the side rails. This embodiment describes the case where there are two outer rails 2 and one inner rail 3. Of course, in other embodiments, if the curtain is too tall, multiple outer rails 2 and inner rails 3 may be required. In this case, it is sufficient to ensure that there is only one more outer rail 2 than inner rail 3, with the outer rails 2 at both ends of the side rails. In a preferred embodiment, the length of the outer rail 2 is greater than half the length of the inner rail 3.

[0032] For details, see Figure 2 The outer rail 2 includes an outer rail bottom edge 2-1 and outer rail side edges 2-2 connected on both sides of the outer rail bottom edge 2-1, an outer rail folded portion 2-3 is provided on the outer rail side edge 2-2, and an insertion cavity 2-4 is formed between the outer rail folded portion 2-3 and the outer rail side edge 2-2; the inner rail 3 includes an inner rail bottom edge 3-1 and inner rail side edges 3-2 connected on both sides of the inner rail bottom edge 3-1, an inner rail folded portion 3-3 is provided on the inner rail side edge 3-2, and the inner rail folded portion 3-3 cooperates with the insertion cavity 2-4.

[0033] A first shading portion 2-5 is symmetrically positioned on the outer rail's folded portion 2-3, and a second shading portion 3-4 is symmetrically positioned on the inner rail's side edge 3-2. Both the first shading portion 2-5 and the second shading portion 3-4 are equipped with shading brushes, providing shading at both the front and rear ends of the curtain's sides, enhancing the shading effect. As a preferred option of this embodiment, the first shading portion 2-5 is flush with the second shading portion 3-4, allowing for a smooth transition between the outer rail 2 and inner rail 3 during retraction and deployment, preventing the curtain from being caught by protruding portions.

[0034] A third shading portion 3-5 is provided on the side of the inner rail bottom edge 3-1 facing the outer rail bottom edge 2-1, and a shading brush is provided in the third shading portion 3-5. Since there is a tiny gap between the inner rail 3 and the outer rail 2, a shading brush is installed on the third shading portion 3-5 to avoid light leakage between the gaps.

[0035] The first shading part 2-5, the second shading part 3-4 and the third shading part 3-5 are all "T"-shaped inlay grooves, and the opening of the inlay groove is smaller than the bottom. The shading brush is adapted to the shape of the inlay groove. The shading brush can be fixed after being embedded. The installation is relatively simple and does not require glue, screws, etc. to fix. It will not fall off easily.

[0036] The bottom edge 2-1 of the outer rail is provided with a calibration slot 2-6 to facilitate drilling during production and to locate the centerline position during later installation. During later installation, the shading strip is stretched to the required height and the side rails are fixed to the wall with screws.

[0037] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
