Therefore, as shown in Figure 1, by using a door hinge assembly (1) of the form embedded in the door frame, to the structure that combines the latch (4) engaging the door hinge assembly on one side corners of the lower and top of the door. Is installed.

In the door hinge assembly according to the prior art, when the door is opened by applying an external force, the door hinge assembly according to the prior art does not stably maintain the state as long as the door is opened without moving. In other words, the door closes automatically or seems to remain open, but closes easily with a slight external force.

Therefore, while the elderly and children who are not agile in response to external situation changes know that the door is open, the door is suddenly closed by an air pressure car and injured while not aware that the door is open, and there is a risk of safety accident. For example, if someone else keeps the door open or if there is no other person, the door must be opened with the object in front of the door, and the door must not be closed with one foot. . In addition, even if it is necessary to leave the door open for ventilation, there is a problem that you need to hold the door until the ventilation is completed, or to use a support or a heavy object, or a specially designed tool or device.
