FRONT DOOR SECURITY DEVICE
The present invention relates to a front door security device capable of preventing an intruder from forcibly opening a front door being closed while a resident enters the house through the front door. The front door security device of the present invention includes a main body; a belt unit having one end fixed to the front door and the other end woundably connected to a spool installed in the main body; a ratchet gear unit that allows the spool to rotate in one direction in which the front door is closed and prevents the spool from rotating in the other direction in which the front door is opened; an encoder unit that detects the open or closed state of the front door in real time through the rotating direction of the spool; and a control unit that prevents the front door from being forcibly opened when it is sensed that the rotating direction of the spool is switched to the front door opening direction while the front door is being closed.
본 발명은 거주자가 현관문을 통해 집안으로 들어오는 도중에 외부 침입자가 닫히고 있는 현관문을 강제로 열지 못하도록 할 수 있는 현관문 방범장치에 관한 것이다.
