Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is an entrance door that allows escape in an emergency, and more specifically, an entrance door for a house such as a house, especially a concrete condominium, which can be easily handled by hand even if the entrance door breaks due to an earthquake or fire It relates to the entrance door that can be pushed down to escape. In an independent house, even if the entrance door does not open due to an earthquake etc., there is a space around it, and it is possible to escape from the back window or back door, but in an apartment etc. the exit is only the entrance, and it can be the upper floor above 2 floors The more difficult it is to escape. In that sense, it can be said that the entrance door of the present invention is suitable for a concrete apartment house.
[0002]
[Prior art]
When a house collapses due to an earthquake, there is a tragedy in which residents are confined in the house because the entrance door does not open when the area around the entrance is distorted even if it does not collapse. Also, when the door is closed with a finger between the vertical stile of the door and the outer frame in normal use, an infant's thin finger may be caught in the gap between them, causing an accident such as a fracture. .
[0003]
This danger is due to the fact that the conventional entrance door has a hinged opening and closing mechanism. Hinge attachment is permanent and cannot be easily removed even if it is distorted by an earthquake. In addition, the fingers are sandwiched between the doors at 90 degrees to allow hinges to be connected, and there is no gap when the door is closed. If a resident, especially an infant, closes the door with a finger in the gap, it will be pinched as it is and an accident will result in a finger fracture.
[0004]
From this point of view, the present inventor has completed the utility model registration No. 3071004. The above idea and features will be described with reference to FIG. 4. In an emergency when the door is partially broken due to an earthquake and cannot be opened from the inside, the driver 17 is inserted into the screw 25 of the working unit 18 that operates the upper pivot pin 16 of the door. Then, the screw was rotated to retract the pivot pin 16 so as to be detached from the upper frame. The driver 17 is always stored in a pocket 19 provided inside the door.
[0005]
[Problems to be solved by the invention]
However, in this case, the essential driver 17 is not necessarily securely held in the pocket 19 and may not be found in an emergency. Also, if an earthquake occurs at night, a power outage is expected, and the resident is usually panicked. In such a mental state, it is very difficult to take out the driver 17 from the pocket 19 and to operate the screw 25 by groping in the dark. Because he is panicking, the driver 17 may be dropped from the hand. Once dropped, it is almost impossible to find a small driver 17 in the dark, panic, and with the furniture scattered.
[0006]
As an advantage of the previous device, the driver 17 has a long handle and can be applied with a large force. For this reason, the coupling mechanism between the screw 25 and the pivot pin 16 can be manufactured with relatively little care. Therefore, for example, it was possible to cope with conventional techniques using racks and pinions.
[0007]
Considering the problems and advantages described above, the problems exceed the advantages. Moreover, the problem with such devices is not just a matter of taste. It rarely happens, but once it happens, it is related to human life. It's too late to happen. There is a need for improvement here. The point of improvement is to improve the pivot mechanism of the pivot pin 16 so that the operation tool of the pivot pin 16 can be handled easily and simplified.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, the entrance door is pivotally supported by the upper and lower frames constituting the entrance through the upper and lower pivot pins ,
An operating mechanism for pushing down the upper pivot pin is engaged with the first gear having a first gear having an axis perpendicular to the surface of the door and an axis perpendicular to the surface of the door. a second gear is constituted by a connecting rod for connecting said pivot pin and said second gear,
At the tip of the shaft of the first gear, a knob is attached so as to be rotatable about an axis along the surface of the door,
Rutotomoni pay working portion of the actuating mechanism in a recess formed in the side surface of the indoor side of the door, wherein the working portion, said knob in an emergency through the shaft upright rotating said first gear Is contained,
Always by attaching a lid rotatably edge of the working portion is the working unit is characterized by being closed by the lid.
[0009]
[Effects of the Invention]
Since the entrance door is a pivot pin that can move up and down without using a conventional hinge, even if the door does not open due to an earthquake or fire, the door can be easily operated by operating a simple work section provided inside the door. The upper pivot pin can be retracted so that the door can be easily pushed out of the room. Moreover, since the working part does not protrude from the side surface on the indoor side of the door, there is no problem in daily life.
[0010]
Furthermore, since the door is attached not by a hinge but by a shaft, the corner of the door can be formed in an arc shape (so-called round shape) as indicated by reference numeral 21 in FIG. There is no longer any worry or danger of injury.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The front door 1 is supported by being inserted into a pivot pin hole 5 having an upper frame formed with a pivot pin 6 that protrudes upward and backward. Even if it is said to be able to move forward and backward, it is maintained in a protruding state during normal times and fulfills the function of pivoting the door. If an emergency such as an earthquake does not occur, the situation will last forever. If an emergency occurs and the pivot pin 6 is removed from the pivot pin hole 5, the door is removed by hand. 1 and 2, a working portion 10 of the door pivot pin 6 is formed in the vicinity of the left corner of the door 1 as viewed from the room. The working unit 10 is formed as a recess as shown in FIG. 1 so as not to protrude from the rear surface of the door (inside the room). In the illustrated embodiment, a lid 11 is hinged to the lower edge of the opening of the working unit 10 in the illustrated embodiment and opens and closes in the direction of the arrow in FIG.
[0012]
In the working unit 10, the head of a screw 7 integral with the shaft of the first gear 2 protrudes in the room direction, and a knob 9 is rotatably attached by a pivot 8. The knob 9 is normally housed in the working unit 10 in FIG. 1. In the event of an emergency, if the knob 9 is raised forward and rotated in the direction of the arrow in FIG. 2, the first gear 2 rotates clockwise in FIG. As the second gear 3 rotates counterclockwise, the connecting rod 4 is pushed downward.
[0013]
The operation of the gears 2 and 3 is the lifeline of the present invention. Daily treatment is important so that the gear group can be operated with a slight force. However, it is virtually impossible to maintain such a mechanism in preparation for natural disasters that do not know when it will come, and there is no value as an invention if an amateur resident is expected to do so. It is desirable to function in the event of no maintenance. Therefore, in the present invention, consideration is given to maintaining airtightness as a countermeasure against rusting of the gear mechanism and providing an appropriate lubricating oil injection port at a suitable location, but the method is within the scope of conventional technology, so details Omitted.
【The invention's effect】
When the connecting rod 4 is pushed down, the door pivot pin 6 is pushed down accordingly, and the door is detached from the upper frame so that it can be pushed outward by hand. This eliminates the danger of residents being trapped inside the house.
[0014]
Since the corner of the door 1 in the vicinity of the pivot pin 6 has an arc shape (see reference numeral 21 in FIG. 4), it is possible to prevent an accident in which a finger is caught between the vertical stile and the vertical frame regardless of the inside or outside of the house.
