Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a coverless rolling curtain. Background Art

[0002] Existing coverless roller blinds have some obvious limitations in design and use. These problems are mainly reflected in two aspects:

[0003] The first is light leakage from the top. After installing a hoodless roller blind, a gap often appears at the top due to the varying thickness of the fabric on the roller when the blind is lowered, causing light to leak into the room from the top. When the blind is fully lowered, the fabric on the roller overlaps minimally, maximizing the space above the roller and causing the most light leakage. Light leakage from the top not only affects the blind's light-blocking effectiveness and reduces its practicality, but also compromises the user's visual comfort, especially in situations where complete light blockage is required, such as when sleeping or watching a movie.

[0004] Second, the lack of aesthetic appeal. Existing hoodless roller blinds typically feature a single cylindrical roller shaft, lacking decorative appeal. When the roller shaft is exposed, it becomes difficult to blend in with the surroundings, especially in interiors where detail is paramount. It easily becomes a focal point, severely impacting the overall aesthetic of the curtain and failing to meet the aesthetic requirements of modern curtain design. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects of the prior art and provide a coverless rolling curtain.

[0006] In order to achieve the above purpose and other purposes, the present invention is implemented by including the following technical solutions: the present invention proposes a coverless roller blind, including a side bracket; a roller, whose two ends are respectively fixed on the two side brackets, for winding up the curtain cloth; a support assembly, whose two ends are respectively fixed on the two side brackets, and is arranged at the front end and lower end of the roller, and its upper end is not lower than the upper end surface of the roller after all the curtain cloth is wound around it; the curtain cloth is wound around the support assembly from the top of the roller forward, creating an appearance of a cover at the front end and lower end of the roller.

[0007] In one embodiment, the support assembly includes a first support member, and an upper end surface of the first support member is an arc surface.

[0008] In one embodiment, the support assembly is arranged at the front end and the lower end of the roller, and the curtain fabric is wound on the support assembly from the top of the roller forward, creating a cover appearance at the front end and the lower end of the roller.

[0009] In one embodiment, the support assembly includes a first support member, a second support member and a third support member, the upper end surface of the first support member is not lower than the upper end surface of the roller after all the curtain fabrics are wound around it; the second support member is vertically arranged below the first support member, and its lower end surface is lower than the lower end surface of the roller after all the curtain fabrics are wound around it; the third support member is horizontally arranged behind the second support member.

[0010] In one embodiment, the third support member is located behind the reel.

[0011] In one embodiment, the curtain fabric is sequentially wound around the front upper end of the first support member, the front lower end of the second support member, and the upper end of the third support member starting from above the winding shaft.

[0012] In one embodiment, the contact surfaces between the first supporting member, the second supporting member and the third supporting member and the curtain fabric are arc surfaces.

[0013] In one embodiment, the first support member, the second support member and the third support member are all cylindrical.

[0015] In one embodiment, the curtain fabric is wound around the upper end, the front end and the lower end of the first support member and the upper end of the second support member in sequence starting from above the winding shaft.

[0016] In one embodiment, contact surfaces between the first supporting member and the second supporting member and the curtain fabric are arc surfaces.

[0017] In one embodiment, the first support member is a rectangular parallelepiped with semicircular arcs at the upper and lower ends, and the second support member is a cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The utility model provides support assemblies at the front and lower ends of the roller, and the upper end of the support assemblies is not lower than the upper end surface of the roller after all the curtain fabrics are wound around it. This allows the curtain fabrics on the support assemblies to completely cover the roller and the curtain fabrics on it. Therefore, as the curtain fabrics are lowered, the upper end of the coverless roller blind will not move downward as the thickness of the curtain fabrics decreases, thereby greatly improving the light leakage problem existing in traditional coverless roller blinds.

[0020] 2. The curtain fabric is wound forward from the top of the roller onto the support assembly, so that the curtain fabric creates a cover appearance at the front end or the front end and the bottom end of the roller, which can achieve the visual effect of the unshaded roller blind being curtain fabric from top to bottom, thereby improving the integrity of the curtain and achieving the effect of beautifying the appearance;

[0021] 3. The utility model adopts a three-cylinder support component design to create a cover appearance at the front and bottom ends of the scroll, which can save the raw materials of the support parts to the greatest extent and reduce production costs;

[0022] 4. The present invention creates a cover appearance at the front and lower ends of the roller shaft, and adopts a support assembly design with two support members, which can simplify the overall installation process of the coverless roller blind. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to avoid confusion with the present invention, some technical features known in the art are not described.

[0034] Example 1

[0035] Please combine Figure 1 and Figure 2 This embodiment provides a coverless roller blind 10, comprising a side bracket 13, a roller 11, and a support assembly 12. The ends of the roller 11 are respectively fixed to the two side brackets 13 for winding up curtain fabric 14; the ends of the support assembly 12 are respectively fixed to the two side brackets 13 and are arranged at the front end and lower end of the roller 11, with the upper end thereof not lower than the upper end surface of the roller 11 after winding up all the curtain fabric 14; the curtain fabric 14 is wound forwardly on the support assembly 12 from the top of the roller 11, so that the curtain fabric 14 creates a cover-like appearance at the front end and lower end of the roller 11, thereby achieving the visual effect of the coverless roller blind being curtain fabric from top to bottom, improving the integrity of the curtain, and achieving the effect of beautifying the appearance.

[0036] At the same time, this design allows the curtain fabric 14 on the supporting assembly 12 to completely cover the roller 11 and the curtain fabric 14 thereon. Therefore, as the curtain fabric 14 is lowered, the upper end of the coverless roller blind 10 will not move downward as the thickness of the curtain fabric 14 decreases, thereby greatly improving the light leakage phenomenon existing in traditional coverless roller blinds.

[0037] Specifically, the support assembly 12 includes a first support member 121, a second support member 122 and a third support member 123. The first support member 121, the second support member 122 and the third support member 123 are all cylinders. The upper end surface of the first support member 121 is not lower than the upper end surface of the roller 11 after all the curtain fabrics 14 are wound around it; the second support member 122 is vertically arranged below the first support member 121, and its lower end surface is lower than the lower end surface of the roller 11 after all the curtain fabrics 14 are wound around it; the third support member 123 is horizontally arranged behind the second support member 122; the curtain fabric 14 is wound around the front upper end of the first support member 121, the front lower end of the second support member 122 and the upper end of the third support member 123 in sequence from the top of the roller 11, so that the curtain fabric 14 creates a cover appearance at the front and lower ends of the roller 11.

[0038] It should be noted that it is not necessary for the first support member 121, the second support member 122, and the third support member 123 to be cylindrical. This design saves raw materials for the support members and reduces production costs. In other embodiments, the first support member 121, the second support member 122, and the third support member 123 can also have other desired shapes, as long as the contact surface with the curtain fabric 14 is a circular arc surface, such as a rectangular parallelepiped with semicircular arcs at the upper and lower ends.

[0039] Furthermore, the third support member 123 is located behind the reel 11 . This design allows the third support member 123 to be closer to the window, thereby preventing the curtain fabric 14 from being too far away from the window and causing unnecessary light leakage.

[0040] Example 2

[0041] like Figure 3 As shown, this embodiment provides a hoodless roller blind 20, which differs from embodiment 1 in that the support assembly 22 only includes a first support member 221 and a second support member 222. This embodiment uses only two support members, which can simplify the installation of the hoodless roller blind 20 compared to embodiment 1.

[0042] Specifically, the first support member 221 is a rectangular parallelepiped with semicircular arcs at its upper and lower ends. The upper end surface of the first support member 221 is no lower than the upper end surface of the reel 21 after all the curtain fabrics 24 are wound around it, and the lower end surface of the first support member 221 is lower than the lower end surface of the reel 21 after all the curtain fabrics 24 are wound around it. The second support member 222 can be a cylinder and is horizontally arranged behind the first support member 221. The curtain fabric 24 is sequentially wound around the upper end, front end, and lower end of the first support member 221, as well as the upper end of the second support member 322, starting from above the reel 31. This creates a cover-like appearance for the curtain fabric 24 at the front end and lower end of the reel 21.

[0043] Example 3

[0044] Please combine Figure 4-Figure 6 This embodiment provides a hoodless roller blind 30, comprising side brackets 33, a reel 31, and a support assembly 32. The reel 31 has its two ends fixed to the two side brackets 33, for winding up curtain fabric 34. The support assembly 32 has its two ends fixed to the two side brackets 33, and is disposed at the front end of the reel 31, with its upper end no lower than the upper end surface of the reel 31 after winding up all the curtain fabric 34. The curtain fabric 34 is wound forwardly around the support assembly 32 from above the reel 31, allowing the curtain fabric 34 to naturally droop at the front end of the reel 31. This creates the visual effect of a hoodless roller blind being entirely covered with curtain fabric from top to bottom, thereby improving the integrity of the curtain and enhancing its appearance.

[0045] At the same time, this design allows the curtain fabric 14 on the supporting assembly 32 to completely cover the roller 31 and the curtain fabric 34 thereon. Therefore, as the curtain fabric 34 is lowered, the upper end of the coverless roller blind 30 will not move downward as the thickness of the curtain fabric 34 decreases, thereby greatly improving the light leakage phenomenon existing in traditional coverless roller blinds.

[0046] Specifically, the support assembly 32 may only include a first support member 321, and the upper end surface of the first support member 321 is an arc surface. Figure 5 As shown, the first support member 321 may be a cylinder; Figure 6 As shown, the first support member 321 may also be a cuboid with semicircular arcs at the upper and lower ends.

[0047] Therefore, the present invention effectively overcomes the shortcomings of the prior art and possesses high industrial value. The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
