About the Security Device "Net Launcher® "
Nippon Koki Co., Ltd. to which Mr. Takahiro Yamada and his colleagues belong, has developed a new crime prevention tool, the "Net Launcher® ", which deploys a net to restrain a suspicious person a few meters away.
Net Launcher® has four features.
First, since it uses a non-explosive gas generator, it is not subject to the Explosives Control Act, and there are few restrictions on its handling.
Second, the net can be used at a distance from a suspicious person because of its flying mechanism, whereas in the past it was necessary to confront a suspicious person using a man catcher.
Third, the weights used to make the net fly were designed to fly radially in eight directions so that the weights would not strike the target directly, thus ensuring safety.
Fourth, by using a gas generator instead of high-pressure gas, the total weight was reduced to less than 1 kg.
The machine can be easily handled by women and other people who are not strong enough to handle it because there is almost no recoil when it is operated.
I In the development stage of this product, they evaluated the flight path of the weight and conducted wind tunnel tests to evaluate the effect of wind on the deployability of the net, which is an important condition, and designed a net that can be deployed reliably.
Net Launcher® is gaining recognition as an effective crime prevention tool due to its convenience in that it does not classify as explosives and the safety of flying objects, and is used by many organizations including kindergartens, elementary and junior high schools, hospitals, local crime prevention associations, and police.
Net Launcher® has opened up a new product field by applying the knowledge gained from the development of explosives to non-explosive products.
Since Net Launcher® was launched in 2005, improved products were launched in 2007 and 2008, continuing its contribution to the crime prevention field.
These achievements are the result of their contributions to new fields of explosives technology, and they are worthy of the Japan Explosives Society Technology Award.
