  The invention according to Patent Document 1 is intended to ensure the opening of the door even by deformation of the door frame due to an earthquake. By rotating the knob, the gear group stored in the door is operated to rotate the pivot shaft. It can be moved to open the door. In Patent Document 1, as a specific configuration, the head of a screw 7 integral with the shaft of the first gear 2 protrudes in the working portion 10 in the indoor direction, and the knob 9 is pivoted by the pivot 8. It is pivotally attached. The knob 9 is (generally) normally housed in the working unit 10, and the first gear 2 is rotated clockwise in FIG. And the second gear 3 rotates counterclockwise as the second gear 3 rotates counterclockwise. Accordingly, a configuration is disclosed in which the connecting rod 4 is pushed downward. Further, it is described that the operation of the gears 2 and 3 is important in the configuration, and that there is a concern about the problem that the gears are not maintained.

  However, with regard to operability based on the configuration, it is complicated in an emergency to continuously perform an operation of raising the knob toward the front and an operation of rotating the knob only in a predetermined rotation direction. For example, in the description of the comparison with the prior art in Patent Document 1 (paragraph number 0005), “If an earthquake occurs at night, a power outage is expected, and the resident is usually in a panic state. In addition, it is very difficult to grope in the dark (omitted). ”As it is, it is difficult to determine whether the knob rotation operation in the dark is correct to turn right or to the left. . Furthermore, when maintenance of the rotation mechanism of the knob is insufficient, it is very difficult to open the door. In order to rotate the knob, it is necessary to apply a certain amount of force to the fingertip and wrist, and depending on the degree of maintenance, it may be impossible for the elderly and children in particular.

  On the other hand, as shown in Patent Document 2, the pivot shaft protrudes from the upper and lower ends of one side of the door, and the pivot shaft is rotatably supported in the vicinity of the upper and lower ends of the door frame. The door mounting structure that can be freely opened and closed allows the pivot shaft to be retracted even if the side wall and the side frame of the door frame are in a pressure contact state in the event of an earthquake. It can be considered that it is possible to remove the entrance door from the door frame by applying it to the entrance door as in 1.

  However, the invention according to Patent Document 2 is configured only on the assumption that it is used for hanging a door of a simple and light bathroom or the like. This is a configuration in which the operation knob attached at a high place must be kept downward against the impact resilience force. For this reason, when the above configuration is applied to heavy doors such as entrance doors, it is a fact that elderly people and children who are not accustomed to hanging the doors can remove the doors while holding the lever downward with one hand. If it is possible to keep it down, even if it is possible, it will tilt the door to the worker side, so the balance when holding the door will be worse and there is a risk that the door will fall to the worker side It is very expensive and may fall with the door and lead to important things.

  The present invention has been made in view of the above circumstances, and is a detachable device for emergency response doors that is truly highly operable, can be operated even by children and elderly people, and has high safety during opening work. And provision of the emergency response door using the same is a problem to be solved by the invention.
