A tensioned punchless window shade system

Abstract

This utility model discloses a tension-type no-drill curtain system, including a mounting rail with tension heads installed at its ends and at least one roller blind shell connected parallel to the mounting rail. The mounting rail is installed on the window frame via the tension heads at its ends, and the length of the roller blind shell is matched to the window frame size. This utility model's curtain track uses a multi-track design, making the no-drill mounting track independent of the roller blind tube. This eliminates the need to leave tensioning and expansion areas at both ends of the conventional tension-type no-drill roller blind tube. Therefore, compared to existing tension-type no-drill roller blinds, the roller blind tube length is set closer to the width of the window frame, allowing the width of the curtain fabric wound around it to better match the window frame. After installation, the curtain system of this utility model has a smaller gap between the curtain fabric and the window frame, stronger light-blocking and light-prevention capabilities, and a stronger shading effect on the window frame when unfolded, resulting in a more aesthetically pleasing overall appearance.

Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a tension-type, no-drill curtain system. Background Technology

[0002] Curtains are common household items that prevent direct sunlight from entering the room, thus protecting the indoor environment. There are various types of curtains, including but not limited to roller blinds and Venetian blinds based on structural design. Over the years, roller blinds have evolved into fixed-mount and expansion-tension roller blinds. Expansion-tension roller blinds are characterized by their telescopic mounting mechanism, allowing for installation without drilling holes in the window frame. They can adapt to slightly different window sizes. These drill-free expansion-tension blinds are also widely used in Venetian blinds and other similar designs. However, unlike Venetian blinds, roller blinds require the fabric to be wound onto a roller tube for storage. Due to the expansion-tension structure, the main structure of the curtain shell... Since both ends of the roller blind are equipped with tensioning heads, the width of the groove between the curtain roller tube and the window frame cannot be matched. Therefore, in existing tensioning roller blinds, after the curtain is unfurled, there is usually a gap on both sides of the curtain width from the inner wall of the window frame that is equal to or greater than the extension length of the tensioning head. This gap not only allows the window frame and window to be seen directly, but also, due to the space between the curtain and the window glass, outdoor light will be refracted into the room through the gap, thus affecting its light-blocking effect. This makes the tensioning no-drill roller blind a defect that greatly affects its use in practical applications. Utility Model Content

[0003] In view of the existing technology, the purpose of this utility model is to provide a design for a tension-type, punch-free roller blind system, which features a smaller gap between the curtain and the window frame after installation, stronger light blocking and light leakage prevention capabilities, and a more aesthetically pleasing overall appearance.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tension-type hole-free curtain system, including an installation rail with a tension head installed at the end and at least one roller blind shell connected in parallel with the installation rail. The installation rail is installed at the window frame through the tension head at the end, and the length of the roller blind shell is set to match the size of the window frame.

[0005] As a further feature of the above solution, the length of the mounting rail is less than the length of the roller shutter shell, and the end of the mounting rail is provided with a telescopic groove for a tensioning head.

[0006] As a further feature of the above solution, the mounting rail is fixedly connected to the roller shutter shell.

[0007] As a further feature of the above solution, a slot structure is provided between the mounting rail and the roller shutter shell for axial movable engagement, and screws are also provided for connection and fixation between the mounting rail and the roller shutter shell.

[0008] As a further provision of the above scheme, the mounting rail and the roller shutter shell are installed side by side in a direction perpendicular or horizontal to the window.

[0009] As a further feature of the above scheme, the roller shutter housing is provided with a roller shutter track tube, which is used for winding the roller shutter fabric.

[0010] As a further feature of the above scheme, the end of the roller blind track is also provided with a roller blind control head, which adopts a beaded roller blind system.

[0011] As a further provision of the above scheme, the roller shutter track tube is equipped with an electric mechanism or a spring mechanism, both of which are used to control the rotation of the roller shutter track tube relative to the roller shutter shell.

[0012] Beneficial effects: This utility model's expansion-type no-drill curtain system, applied in the field of roller blinds, compared with existing technology solutions, uses a multi-track design for the curtain track, making the no-drill installation track independent of the roller blind tube. This eliminates the need to leave expansion and contraction areas at both ends of the conventional expansion-type no-drill roller blind tube. Consequently, compared with existing expansion-type no-drill roller blinds, it allows for a roller blind tube length closer to the width of the window frame, resulting in a better fit between the width of the curtain fabric and the window frame. The expansion-type no-drill roller blind system of this utility model has a smaller gap between the curtain fabric and the window frame after installation, providing stronger light blocking and light leakage prevention capabilities. When unfolded, it also provides stronger shading of the window frame and a more aesthetically pleasing overall appearance. Attached Figure Description
