Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problems: a conventional revolving door is dangerous such as in the case of the Roppongi Hills (R) where a child was pinched to death (as shown in Fig.1); on the other hand an auto-locking door as shown in Fig.2 allows an outsider following a legal passenger to illegally enter a building, and therefore it is not safe in terms of crime prevention or does not exert windbreak performance. <P>SOLUTION: There is provided a safety door which is formed of double door elements so that the second door element does not open unless the first door element is closed. Further a space defined by the two door elements is set to about an extent where only one person can stand, and therefore the safety door can exclude an intruder. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an entrance door.

  Conventionally, there is a revolving door type as shown in FIG. 1 or a sliding type as shown in FIG.

  As shown in the example of Roppongi Hills, the conventional revolving door as shown in FIG. 1 is dangerous, such as the death of a child when it is caught. Moreover, since there is no windshield, there is a lot of air conditioning loss.

  A double door is used so that the second door does not open unless the first door is closed, and the space between the two doors is a space for about one person to enter.

  In the conventional auto-lock type, it was impossible to prevent a follow-in intruder, but this tracking thief invasion was prevented, it had a windshield action, and it was safe and low-cost without being caught, and escape was possible quickly.

  As shown in FIG. 3, a double door is provided, and the two doors are interlocked to make the space of the two doors into a space for about one person.

  FIG. 1 shows a known revolving door, in which a cylindrical glass 2 is provided in a part of a partition 1, a rotating shaft and a motor are provided at the center 3 of the cylindrical glass, and the glass is rotated by the motor 3 around the rotating shaft. Although the door 4 is provided, there are many accidents in various places such as Roppongi Hills where the entering person 5 is caught in the door 4 and is dangerous. In addition, it cannot be auto-locked and more than one person can enter the revolving door.

  FIG. 2 also shows a well-known auto-lock door, where a sliding door 6 is provided in the partition 1 and a specific registrant 8 can enter by pressing a personal identification number button 7, but it is not specified while the door 6 is open. If another person 9 follows the registrant 8, the door 6 is open so that the person can enter. Therefore, it is defenseless for crime prevention. Further, since the door is opened and closed, it cannot be shielded from wind, and cold air and warm air enter the room 10 to reduce the air conditioning effect.

FIG. 3 shows an embodiment of the present invention. Doors 11 and 12 are provided at the opening of the wall 1 and supported by hinges 13 and 14 to open and close. The door 11 and the door 12 are locked by a lock 15 and a lock 16, respectively. At the entrance is a button 7 for pressing a personal identification number. When the specific person 8 presses the button 7 with the personal identification number, the lock 15 of the first door 11 is released and the first door 11 is opened. Can enter the space 17 between the first door 11 and the second door.
Even if an unspecified person 9 tries to enter while the first door 11 is open, the space between the first door 11 and the second door 12 is a narrow space that can be entered by only about one person. It can only be entered, and the unspecified person 9 cannot enter because there is no space for entering. Even if it enters, the specific person 8 and the unspecified person 9 enter the narrow space 17 of the first door 11 and the second door 12 together, so that the specific person 8 recognizes the unspecified person 9. Or, however, you can exclude it from entering. Since a switch 18 for the second door is provided in the space 17 between the first door 11 and the second door 12 and a person entering the space 17 presses the switch 18, the lock 16 of the second door 12 is released. The door 12 can be opened to enter the room. When exiting, the lock 16 is removed and the second door 12 is opened, the lock 15 is removed, the first door 11 is opened, and the user can quickly exit. Reference numeral 19 denotes an electric circuit for controlling them. Since the present invention is configured as described above, it is possible to prevent an unspecified person from entering as in the known auto-lock shown in FIG. 2, and the space 17 also serves as a windshield room. Since the throat is stagnant, there is no intrusion of cold or warm air, so the air conditioning effect is good, and since the doors are opened one by one, there is no accident where people are caught between the motor 3 and the revolving door 4 as shown in FIG.

FIG. 4 shows an embodiment of the electric circuit 19 in FIG. As a result, the electric lock 15 is opened by the password, and the second door lock 16 is activated while the first door is open, the first door is closed, and the second door switch 18 is pressed. Only the electric circuit in which the lock 16 of the second door is released.
The above is an embodiment of the present invention. For example, the first door is a slide-type auto-lock, all the doors are slid, the number of doors is two or more, and various combinations and structures However, any change in the electric circuit can be considered, and these are all included in the present invention.
