That is, in the door closing confirmation device 10 of the present invention, the door opening means for moving or rotating by the motor 11 or the electric actuator 12 is installed in the door frame 1a, The door opening detecting means for detecting whether or not the door is opened is provided at a position adjacent to the door opening means or between the door and the door frame.

As shown in FIG. 2 and FIG. 3, the door opening means is provided with a case 13 on the door frame 1a, and the door 13 is provided on the shaft of the motor 11 installed inside the case 13 And a rack 15 which is engaged with the pinion 14 is installed movably in the case 13 and is driven by a pinion 14 rotated by the operation of the motor 11, 15 are moved so as to apply an opening force to the door 1 in the opening direction of the door 1.

Then, if the locking device 2 of the door 1 such as the front door operates properly and the door 1 is not opened, it can be confirmed that the door 15 is not moved and the door 1 is properly locked. 1 is opened and the rack 15 is moved, the door opening detecting means is turned on.

Accordingly, although not shown, the controller can notify the user through the speaker, which is a warning light, as the door opening detecting means is turned on.

In the case of a fire door or the like, the closing force of the door locker is confirmed. When the door is closed, the motor 11 or the electric actuator 12 described below is actuated to open the door by the door opening means. It is possible to confirm the reference value closing force of a door of a refrigerator or the like.

It is obvious that the power of the motor 11 or the electric actuator 12 is determined according to the opening force of a door such as a door or a fire door.

On the other hand, in the case of the locking apparatus of the EM lock system which locks the door by the magnetic force, since the closing force of the door is very large, the opening of the door can not be confirmed in the same manner as in FIGS.

Therefore, in order to increase the movement force of the rack 15, a reduction gear 16 is installed between the axes of the pinion 14 and the motor 11 as shown in FIG.

Further, in order to further increase the opening force for confirming the closed door 11, the door opening means is provided with a case 13 on the door frame 1a as shown in FIG. 5, A worm 17 is provided on the axis of the motor 11 provided inside and a rack 15 which is engaged with the worm 17 is movably installed in the case 13 and rotated by the operation of the motor 11 The rack 15 is moved by the worm 17 and an opening force is applied to the door 1 in the opening direction of the door 1. [
