Title:
AUTOMATIC CLOSING DEVICE AND AUTOMATIC CLOSING DEVICE UNIT
Document Type and Number:
Japanese Patent JP2017089323
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an automatic closing device that prevents overloading of a motor, when the motor is operated after an opening/closing member is positioned at a closed position in contact with a box body.SOLUTION: An automatic closing device 1 is disposed at a closing position 2A in contact with a box body 3, by driving an opening/closing member 2. The automatic closing device 1 includes a gear mechanism 21 for transmitting driving force of a motor 20 to an output shaft 11, to which the opening/closing member 2 is connected. A transmission mechanism 21 includes a fourth composite gear 26 (a driving force releasing mechanism) at an intermediate position on a driving force transmission route. The fourth composite gear 26 allows an operation to transmit the driving force from the motor 20 to the fourth composite gear 26, when the motor 20 is in operation after an output gear 27 positioned on a downstream side in a transmission direction of the driving force than the fourth composite gear 26 comes to a halt, as the opening/closing member 2 comes into contact with the box body 3 at the closing position 2A. This prevents the entire gear mechanism 21 from coming into a locked state, when the opening/closing member 2 reaches the closing position 2A.SELECTED DRAWING: Figure 9
