Abstract
The present invention relates to a door operating system for controlling the movement of a door, more particularly to “no touch” door openers for public washrooms and households. The system has a motor with a gear chain where the high gear is generally semicircularly shaped engaged with a swinging arm coupled with the door through the roller and a pilot plate. The unit is activated upon receipt of the signal from overhead passive infrared or hand proximity detecting sensors and has a controlling system to provide for opening and closing the door, as well as retraction of the arm in the event of door encountering an obstacle or in an overload condition of the motor. The arm and a gear are linked pivotally with each other and with the unit housing. They are coupled through a spring suspension system and have a clutch mechanism preventing overloading. The only external moving part is the arm, which is, along with geared sector, protected by a flexible member providing security to prevent accidental jamming of objects by it. The unit may be battery operated with a low voltage and low power AC/DC switching wall adapter. In autonomous operation it can provide up to 700 opening cycles without external power.
