Description

Technical Field

[0001] This invention specifically relates to a trackless and frameless glass sliding door. Background Technology

[0002] Traditional glass sliding doors often use floor-mounted tracks that protrude from the ground, posing a tripping hazard and easily accumulating dust, making them difficult to clean and affecting both the aesthetics and safety of the overall design. Meanwhile, some frameless glass sliding doors, while aiming for a minimalist look, have a simple top guide structure, relying solely on a single guide wheel for support. This makes the door prone to wobbling and instability during horizontal movement, and can even lead to derailment.

[0003] Furthermore, existing glass sliding doors often use drilling holes in the glass to fix them to metal brackets. These holes easily create stress concentrations, increasing the risk of glass breakage. They also require high installation precision and are inconvenient to adjust. When the door reaches either end, there is a lack of buffer protection, making it prone to hard collisions with walls or frames, generating noise and potentially damaging the glass. Therefore, how to improve the stability, safety, and ease of installation of glass sliding doors while achieving a minimalist, trackless, and frameless appearance is a pressing technical problem that needs to be solved in this field. Summary of the Invention
