Description

Technical Field

[0001] This utility model relates to the field of free door hinge technology, and in particular to a free door with an integrated upper and lower hinge structure. Background Technology

[0002] In some applications, swing doors cannot be constructed as a single, floor-to-ceiling structure, requiring the door panels to be split into upper and lower sections. Hinges, which allow the door to open and close smoothly and naturally, often require separate connections at the bottom corner of the upper door and the top corner of the lower door when installed on split-section doors. This process is inefficient, aesthetically unappealing, and negatively impacts the user experience. Furthermore, swing doors are typically used frequently, demanding high structural strength and stability. Therefore, designing an integrated hinge structure for swing doors, connecting the bottom corner of the upper door and the top corner of the lower door as a single unit, is essential to improve installation efficiency, maintain aesthetics, enhance the user experience, and ensure structural strength and stability.
