Abstract

PURPOSE:To obtain a condition to capture a criminal and to take back a stolen article by providing a capture net consisting of a rough mesh band having a falling weight at its tip, and a means to drop and expand the net. CONSTITUTION:The burglar preventing net is prepared in a gateway 6 of a building such as a bank, and immediately before a robber 14 runs away from the gateway 6, a net dropping/expanding means 5 is operated. Then, a capture net 1 is dropped and expanded at the gateway 6, and shuts off the escape route of the robber 14. Here, the robber 14 cannot sufficiently confirm the capture net 1 consisting of the rough mesh, the rubber 14 collides with the capture net 1 of himself, pulls out the net, inserts his hands, feet and head into the rough mesh 4, and loses his free action. Thus, the robber is made into a condition in which he cannot run away, and the condition to take back the stolen article and to capture the robber can be obtained.

Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a security net that is installed at the entrance and exit of a building, which is an escape route for bank robbers, etc., and is used to capture criminals, recover stolen goods, etc. .

``Prior Art'' and ``Problems to be Solved by the Invention'' In the case of financial robberies, which often occur, there are few effective means to catch criminals fleeing from building entrances or recover stolen goods, and they are often forced to flee. I often end up.

The present invention was developed in view of the above-mentioned circumstances, and provides a new security net that can be installed at building entrances and exits that serve as escape routes for criminals, and used to capture criminals and recover stolen goods.

``Means for Solving the Problems'' The security net of the present invention that achieves the above objects has ``a coarse mesh made of fine threads through which at least a person's limbs can be inserted;
It consists of a trapping net that forms a band and has a falling weight at the tip, and a net winding section that winds up and stores the long trapping net and attaches it to the upper part of a passageway such as a building entrance. The first invention comprises a structure in which a net falling tensioning means is installed to fall and stretch a catching net at an entrance/exit etc. by the gravity fall of the falling weight, and an intermediate falling weight is provided between the catching net of the first invention. Immediately before a financial robber or the like attempts to escape through a building entrance or exit, a trapping net is dropped and stretched to make escape difficult.

"Function" In the security nets 1 to 1 of the present invention configured as described above, just before a financial robber or the like tries to escape from a building entrance, etc., a trapping net is dropped and stretched over the entrance. Limbs, etc. can get entangled in the coarse mesh of the culprit, making it difficult for the culprit to escape, making it possible to capture the culprit and recover stolen goods.

"Example" Hereinafter, a detailed explanation will be given based on an example. First, with reference to FIG. 1.2 showing the first embodiment of the present invention, the security net of the present invention has a falling weight 3 at the tip and forms a wide band body,
It consists of a trapping net 1 made of a coarse mesh 4 in the shape of a base mesh, and a net winding section 2 that winds up and stores the trapping net 1 and attaches it to the upper part of a building entrance 6. The net winding section 2 includes: When necessary, the captured net 1 that has been rolled up and stored is
A net dropping tensioning means 5 is provided which is pulled out and hung down by the gravity fall of the falling weight 3.

In detail, the capture thread 1 is made of thin transparent nylon thread, and has a base mesh 4 with a coarse mesh 4 large enough to allow human limbs and necks to pass through, and a mesh width B equal to the width of the entrance 6. , it forms a band with a length of 2L, which is approximately twice the falling distance L (vertical distance between the net winding part 2 and the floor surface 13), and several falling weights 3 arranged at arbitrary intervals are placed horizontally at the tip. Installed in a row.

On the other hand, in the net winding section 2, a net drum 8 is rotatably accommodated in a storage box 7 provided at the upper part of the entrance/exit 6, and the net drum 8 winds and stores the catching net 1. It is installed. Further, the net drop tensioning means 5 is composed of an opening/closing plate 9 which pivots at the negative end so that it can be opened and closed freely and which exposes the bottom of the storage box, and an excitation pin 10 which locks the closing position of the opening/closing plate 9. , when the switch 11 connected to the excitation pin 10 is energized, the excitation pin 10 fitted in the locking hole]2 of the opening/closing plate 9 in the closed position
is forcibly retreated and the opening/closing plate 9 is released, and due to its own weight, the opening/closing plate 9 moves to the position shown in the dotted line, the bottom of the storage box 7 is released, and the falling weight 3 on the opening/closing plate 9 is released. .

Then, when the falling tensioning means 5 to the above net 1 is activated,
As shown in FIG. 1 (13) (C), the falling weight 3 rapidly falls to the floor 13 due to its own gravity, and at the same time the catching net 1 is pulled out and falls, and the net winding part 2 and the floor 1
The structure is such that the catching net 1 is automatically hung down and stretched between the three spaces.

The security net having the above structure is installed at the entrance/exit 6 of a building such as a bank, and when the robber 14 activates the net dropping/stretching means 5 immediately before attempting to escape from the entrance/exit 6, the trapping net 1 is placed at the entrance/exit 6. It is dropped and placed in a state that blocks the criminal 14's escape route. However, as the criminal 14 tries to escape from the entrance/exit 6 in a hurry, the criminal 14 cannot sufficiently check the capture net 1, which is made of thin transparent thread and has a coarse mesh, and as shown in FIG. net 1~1
Even if the criminal 14 is in a panic and pulls out his/her own limbs and neck, entangling them in the coarse mesh 4, losing freedom and trying to escape from the trapping net 1, the panicked criminal 14 easily slips into the trapping net 1.
Moreover, the strong thread cannot be easily cut, so the longer the criminal waits, the more difficult it becomes for him to escape, forcing him into a situation where he has to recover the stolen goods or capture the criminal. 'Next, FIG. 3 shows a second embodiment of the present invention, in which a security net comprising the same trapping nets 1 to 1 as in the first embodiment, a net winding section 2, and a net falling tensioning means 5 is used. , the catching net 1 has a length approximately three times the vertical distance between the net winding part 2 and the floor surface 13, and an intermediate falling weight 12 is located at an intermediate position approximately at a distance of IL to 2L from the falling weight 3.
is the provision. According to this second embodiment, when the criminal 14 hits the trapping net 1 and moves forward and tries to escape while dragging the trapping net 1, the intermediate falling weight 12 falls behind the criminal 14 as shown by the dotted line in the figure. However, since the criminal 14 loses his freedom like a fish in a cast net, there is a unique effect that the performance of catching the criminal is further improved.

In the above configuration of the present invention, the trapping nets 1 to 1 may be made of synthetic fiber yarn other than the transparent nylon thread, and the specific size of the coarse mesh 4 may be made finer than in the above embodiments. It should be something that you can fit your hands and feet through. Further, the net dropping and tensioning means 5 may be any known means other than the above-mentioned embodiments, and in short, any means that automatically drops and tensions the catching net 1 by the gravitational action of the falling weight 3 may be used. A sensor may be provided at a key point above the entrance/exit 6, and when a criminal enters, the sensor is turned on to catch the criminal 14 who is trying to escape, and the net dropping/stretching means 5 is automatically activated.

"Effects of the Invention" As explained above, the crime prevention net of the present invention has excellent performance in catching criminals such as financial robbers and forcing them into situations where they recover stolen goods, and has excellent effects that serve as a powerful means of defense against robbers. be.
