Abstract

PURPOSE:To capture a criminal and prevent a crime from occurring by mounting a fence slidable in the lateral direction on the side face of the cylinder of a revolving door, automatically closing the fence when the criminal passes through the door and providing a function, in which the criminal is confined in the revolving door. CONSTITUTION:Fences 5a, 5b only closing the doorway of a door are installed to the side face of a revolving door, to which three doors 2 rotated only in the fixed direction (x) are set up, respectively along the circumferences of an exit 26b and an entrance 26a in the sides of the exit 26b and the entrance 26a. A switch for a gear sliding the fences 5a, 5b in the lower section of the revolving door is pulled before a criminal passes through the revolving door, thus interlocking a gear conformed to revolution pushing the doors and the gear engaged with the teeth of the fences 5a, 5b by a chain and tuning the gears. The fences 5a, 5b are closed along rails 4a, 4b, and the criminal is confined naturally in the revolving door, thus capturing the criminal smoothly, then resulting in the intensification of a burglarproof countermeasure, enhancing restraint force to a crime.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a revolving door having a function of capturing a criminal in a cylindrical door extremely smoothly and having an excellent crime prevention property.

[0002]

2. Description of the Related Art When a crime such as a robbery occurs in any store or facility such as a financial institution to a convenience store, the police are used to catch the criminal.
Also, there was no particular security measure.

[0003]

[Problems to be Solved by the Invention] It is only by relying on the police to catch a vicious criminal, which is very economical, labor and time consuming. Nevertheless, the problem may not be solved. Therefore, by installing a criminal capture device at the door that everyone can pass, it is possible to catch the criminal without danger, and it will also prevent crime, so the drawbacks of the future Can be eliminated.

[0004]

According to the present invention, fences are provided in the outer frame of a revolving door to close two entrances and exits, and some gears are provided under the floor of the fence and the revolving door shaft. Provided, fixed with gear stoppers and releasing the gear stoppers in an emergency, those gears mesh, and the fence automatically slides sideways to close in conjunction with the rotation that pushes the door of the revolving door. , The criminal can be locked inside the revolving door, solving the problem.

[0005]

[Operation] In the revolving door of the present invention, when a criminal tries to escape from this door, if the gear that was rotating the revolving door and the gear of the fence are disengaged before the criminal tries to escape from this door, When the criminal tries to get out of the door, the fence slides sideways to the door as the door pushes and closes the door. Therefore, when a crime occurs in the store or the like, it is possible to catch the criminal safely and without relying on others.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First of all, how to use this criminal capture door, usually, while pushing the door 2 in the X direction around the center axis 1 of the door,
6a to 26b, or vice versa. It should be noted that this door is designed to rotate only in the X direction. here,
It is assumed that a crime has occurred in a store equipped with this door. At that point, the clerk would switch on an alarm, etc., but then pull the switch 21 on the criminal capture door before the criminal subsequently tried to escape through the door. Then gear 10
a and 10b fall around the rotating shafts 13a and 13b of the gears, the teeth 11a and 11b and 11a 'and 11b' mesh vertically, and the door 2 is centered on the central axis 1 of the door, and the door 2 is X When pushed in the direction, the gear 21 under the floor 6 also rotates in the same direction about the central axis 1 at the same time, and the gear 14a,
Since 14b is also connected by the chain 16, it simultaneously rotates about the shafts 13a and 13b. Therefore, the rotary shaft 13
Gear 10a vertically meshed with gear 14a centering on a
Meshes with the teeth 23a of the fence 5a, so that the fence 5a closes along the rail 4a in accordance with the rotation of pushing the door 2. Similarly, 10b is rotated by vertically engaging 14b with the rotating shaft 13b, and the shaft 1 engaging with 10b is rotated.
Since 10c centering on 2 meshes with the teeth 23b of the fence 5b, it rotates to move the fence 5b along the rail 4b. The criminals are captured as described above, and the size of each of these gears is adjusted so that the fence closes at a speed three times the rotation speed of the door. This fence 5a,
A ball bearing 24 is packed under 5b so that the fences 5a and 5b can be closed by a light force. Further, the central shaft 1 and the fences 5a and 5b are supported by the ceiling 25, and a ball bearing 24 is also placed here to improve sliding of the fences 5a and 5b.

[0007]

As described above, according to the revolving door of the present invention, the following effects can be obtained. Before the criminal tried to escape through this revolving door, he unlocked the gears so that the gears at the bottom of the door that matched the rotation of the door meshed with the gears of the fence, and the criminal released the revolving door. At the same time as the door rotates to try to escape to the outside, the fence slides sideways at the door entrance and exit, making it possible to confine the criminal inside the revolving door, and when a crime occurs in the store etc. Criminals can be caught very smoothly, and by installing this door, it is possible to strengthen crime prevention measures, such as leading to a restraining force to prevent crime.

Claims (1)

[Claims] 1. Three doors that rotate only in a fixed direction from the center of the cylinder and two fences along the side surface of the cylinder that close the entrances and exits are provided at two places, respectively, before a criminal passes through the revolving door. By sliding the two fences, by unhooking the gear at the bottom of the revolving door, the gear that matches the rotation pushing the door meshes with the gear on the fence so that the criminal is inevitably trapped inside the cylinder. Revolving door characterized by having done.
