PURPOSE:To open and close a door at a speed and angle desired by a person opening the door by opening and closing the door via a computer correspondingly to a value of pressure exerted on a handle portion and sensed by a pressure sensor. CONSTITUTION:A pressure sensor 8, 9 is installed between two semi-circular plates 11 each mounted to a door handle 2, and the handle 2. A computer 4 is provided for processing a pressure value sensed by the pressure sensor 8, 9 and transmitting the signal to a motor 3. To open (or close) the door 1, a person touches the handle 2 and then the pressure sensor 8 (9) senses the pressure and transmits an electric signal corresponding to the pressure value to the computer 4. The computer 4 processes it in several steps and converts it into a voltage or current and transmits the signal to a motor 3, for opening (or closing) the door 1 at a desired speed and angle. |
