Motor-actuated hands-free door opening and closing system

Abstract

A cost-effective, hands-free door opener activated via foot, cane, remote, Bluetooth, security systems, smart home technology, or proximity sensors which promotes hygienic and accessible door operation without physical contact. This device features a linear motion mechanism with a spring-loaded drive wheel, ensuring stable operation across varied surface types, environments, and door orientations. It includes precise control over the angle, distance, and speed of door opening and closing, complemented by user interfaces. Sensors adapt to environmental conditions and user presence, reducing pathogen transmission risks. Programmable delays for door operations cater to different traffic flows and safety requirements. The system supports various motor types and power setups including wireless operation and charging, suitable for retrofitting existing doors in commercial, institutional, and residential areas. Safety features detect obstructions, ensuring seamless operation. This invention integrates robust mechanical design with intelligent sensors integrated by a controller, enhancing door functionality in diverse environments.
