ABSTRACT:
A waste receptacle door opener is set forth herein. The waste receptacle's door is automatically opened upon a user's approach and then automatically closed upon the user's departure. The door opening device includes an active infrared proximity sensor for detecting the presence of a user. An electric motor is actuated by a signal generated by the sensor. An actuator arm on the electric motor pulls a flexible cable attached to the door to pull the door open when the motor is activated. The flexible cable allows the door to be opened in the event of a power failure.
