Claims

[Scope of utility model registration request]

There is a horizontally long fixed frame with an open lower end that is attached to the lower end of the door, and inside this fixed frame it is installed so that it can be raised and lowered.
A horizontally long closing frame with an open lower end surface with packing material attached to both sides of the lower end, and an operating protrusion at the tip that slides laterally when it comes into contact with the door mounting frame, lowering the closing frame. The actuating plate is located between the fixed frame and the closing frame, and is fixed so that the actuating protrusion always protrudes from the fixed frame by tensioning a spring between the fixed frame and the fixed frame. The lower pin of the link, which is slidably provided on the frame and whose upper part is pivotally supported on the fixed frame with a pin, is inserted into the elongated hole of the closing frame, and the protrusion formed on the upper part of this link is engaged with the actuating plate. A lower door closing device characterized in that an operating plate and a closing frame are connected, and a lifting pin attached to the closing frame is fitted into a vertical groove formed in a fixed frame.
