This technology is a non-automatic sliding door device for a door frame with an opening and storage space. When opening or closing the sliding door, the force applied by the user to the drive mechanism is transmitted to a pinion on a rotating shaft and a rack attached to the door, moving the door horizontally.
Manual sliding doors require significant effort to push or pull by hand, making them inconvenient when your hands are full. While electric doors with sensors and motors solve this, they come with higher installation and maintenance costs, and there has been a lack of specific technology to address the drawbacks of both methods.
This technology features a drive lever on the door frame that moves vertically, supported by a lever base fixed to the floor. When the lever is pressed with a foot, the pinion on the rotating shaft pushes the rack horizontally to open the door. The rack is tilted upward in the opening direction, and a guide roller on the rotating shaft, along with a guide rib that limits its height, ensures the pinion and rack remain engaged. An elastic member connecting the door frame and the door provides constant force in the closing direction to assist with automatic return. It can be applied to hospital and laboratory hygiene zone doors, kitchen and warehouse workspaces where hands are often occupied, and restroom or public facility sliding doors, enabling hygienic access without electricity or sensors by allowing hands-free operation.
