Description

Technology Field

[0001] The present invention relates to a handle for a sliding door, and more specifically, to a handle for a sliding door that utilizes a handle profile made of metal or synthetic resin material, which facilitates connection and assembly with a sliding door panel or a sliding door side frame, while suppressing play, noise, or detachment caused by repeated loading. Background Technology

[0003] Sliding doors are a widely used opening and closing mechanism in various spaces, including residential, office, commercial, medical, and public facilities. Compared to hinged doors, they offer the advantages of occupying less space and minimizing interference with movement when opened. In particular, the adoption of sliding doors has become standard in fields such as interior partitions, built-in wardrobes, shower booths, showcases, balcony windows, and interior doors. Consequently, the handle component for opening and closing the door is treated as a critical element that determines usability, safety, durability, and aesthetic quality.

[0004] However, conventional sliding doors have a problem of reduced structural reliability, such as damage or breakage at the joint between the handle and the frame or panel, or the handle becoming detached, because the load generated by pulling and pushing operations during repetitive opening and closing is concentrated on the handle and transferred to the door panel or door side frame.

[0005] In addition, conventional sliding doors vary in panel material, thickness, and frame shape depending on the usage environment, and standard specifications and tolerance ranges inevitably differ by manufacturer. Consequently, they are often designed to fit panels or frames of a specific thickness, and to apply them to other systems, separate handle specifications or separate connecting parts must be added. This results in poor component compatibility of the handle, making universalization difficult.

[0006] In addition, conventional sliding doors have problems such as complex assembly processes or large variations in work quality due to the numerous process variables—including handle alignment, hole machining precision, and tightening torque management—when attaching handles to the sliding door panels or frames, which can easily lead to quality variations depending on the operator's skill level.
