20120144744 | DOUBLE DOOR CONTROLLING APPARATUS AND METHOD THEREOF - The present invention includes, a failure sensing part to sense the failure created in the encoder mode and sensorless mode to control the door; a main control part to convert the main operation part and backup control part mutually when a failure is sensed by the primary operation mode by the failure sensing part after deciding either of the encoder mode or sensorless mode as a primary operation mode and another one is decided as a backup operation mode; and a location/speed conversion part to perform the door control by calculating the door moving distance according to the corresponding mode when the operation mode is converted by the main control part. | 06-14-2012 |
20120073208 | ELECTRIC DOOR-LOCKING SYSTEM USING A CAM - The invention relates to an electric door-locking system to be applied to at least one electric door body that is movable in a sliding manner, and includes forwardly and reversely rotatable screws disposed side by side along a direction in which the electric door body slides at the side of a door frame; a cam assembly provided at a predetermined position of the screws to perform a locking function and an unlocking function; and a sliding unit provided with a locking roller resiliently biased in a direction toward the cam assembly and engaging with the cam assembly to perform the locking function, one end of the sliding unit being rotatably connected to the screw and the other end of the sliding unit being connected to the electric door body. | 03-29-2012 |
20120017517 | ELECTRICAL DOOR - LOCKING DEVICE - An electrical door-locking device includes screws which are rotatable in a forwards and backwards direction, and are placed in line on one side of a door frame in the direction in which the electrical door main body slides; locking hooks located adjacent to the screws; and a sliding unit equipped with a rotatably-provided locking lever having a latch for latching onto the locking hooks when the electrical door main body is closed and is equipped with a locking-lever-pressing part for pressing the locking lever such that the latch of the locking lever unlatches from the locking hooks, and one end of which is rotatably linked to the screws and the other end of which is linked to the electrical door main body. | 01-26-2012 |
