Description

Technical Field

[0001] The present invention relates to a corner connector structure, in particular to a corner connector structure used for a screen apparatus such as a folding screen or a rolling bar screen.Background Art

[0002] A currently used screen apparatus, including both a folding screen window and a rolling bar screen window, often uses a plurality of wheel bodies to bypass a track wire or uses a wire adjusting apparatus to adjust the tightness of the track wire. However, due to such a structural configuration that the current wheel body or the wire adjusting apparatus is assembled on a frame material of a window frame, when a screen is opened or closed, the track wire is prone to swing due to stress, leading to the situation that the track wire often swings out of the track of the window frame, which is prone to result in the situation that the screen is unsmoothly opened or closed or gets stuck when the screen is subsequently opened or closed.

[0003] KR20080029057A discloses a folding insect screen system integrated with a sunshade, including a corner connector structure that connects horizontal and vertical frames. The system features a tension adjustment mechanism mounted on the frame materials, allowing for the adjustment of wires that secure the insect screen and sunshade in place. However, KR20080029057A does not disclose the direct installation of a wire adjuster within the corner connector structure itself. Instead, the wire adjuster is mounted onto pre-processed holes or grooves in the frame materials, requiring additional material preparation and increasing installation complexity.

[0004] CN211776943U discloses a corner connector structure designed for connecting the horizontal and vertical frames of door and window frameworks. The structure includes angle arms with buckle portions and hook portions to facilitate connection and alignment. However, CN211776943U does not disclose integrating a wire adjuster within the corner connector structure. Instead, it focuses on the mechanical connection of frames and components without addressing the adjustment or tensioning of wires.

[0005] CN111322001A discloses a screen wire adjustment and control device featuring a fixing seat with a containing groove and an elastic shifting sheet to facilitate the assembly and disassembly of a thread adjusting body. While this device focuses on improving the ease of handling the wire adjustment mechanism, it is mounted onto frame materials rather than directly integrated into a corner connector structure. CN111322001A also relies on pre-processed grooves or holes in the frame material for installation.Summary of the Invention
