Title: Opening/closing control device for motor-driven shutter
Inventor: WATANABE KOICHI
IPC: E06B9/88
Filed: 1995-06-30
Abstract: PURPOSE: To ensure the stoppage and the proper operation of a motor for opening and closing a shutter by releasing engagement with a locking member in synchronization with the startup of the motor, and causing a detection member to detect the arrival of the turned locking member at a locking position. CONSTITUTION: When a shutter 2 is descending, a locking member is kept in such a state as capable of freely turning toward a locking position. When the shutter 2 further descends, a latch projection 3 begins to catch the latch section of the locking member, and turns the member toward the locking position according to the descend of the shutter 2. Then, the locking member arrives at the locking position when the shutter 2 reaches the lowest limit, and a holding member is engaged with the engagement section of the locking member for restricting the turning motion thereof. In this case, the locking member catches the latch projection 3, and concurrently a detection member detects the locking position of the locking member, thereby stopping a motor for opening and closing the shutter 2.  Also, when the shutter 2 ascends on the startup of the motor, the holding member is released from the engagement section of the locking member in synchronization with the startup of the motor, and releases the projection 3.
