Abstract

An anti-riot device is provided that includes a net containing tube, and multiple shot holes in the upper area connecting with air outlet space. The shot holes are equidistantly spaced from the central axis of the device and are circumferentially angularly inclined. The lower side of the air outlet space communicates with a high pressure gas device. The net containing tube receives a high strength net body and a propellant board with a gas receiving concave shaped surface inside. Multiple bullets received in the shot holes are coupled to a periphery of the net body. The bottom of the net contained tube has multiple gas holes and an air outlet board.

Claims

1. An improved anti-riot device, comprising:

a high pressure gas storage device disposed at a lower portion of the device and being in fluid communication with an air outlet space;

a net containing tube disposed in a front portion of the device;

an air outlet board having multiple gas holes formed therethrough being disposed a lower end of the net containing tube, the gas holes being in fluid communication with the air outlet space;

multiple shot holes circumferentially disposed around an upper end of the net containing tube and in fluid communication with the air outlet space, each of the shot holes having upper and lower ends equidistantly spaced from a central axis of the device and angularly offset one from the other to define a circumferential angular inclination;

a net body having a plurality of bullets coupled to an outer periphery thereof, the net body being disposed in the net containing tube with the plurality of bullets respectively disposed in the shot holes; and

a propellant board having a gas receiving concave surface disposed in the net containing tube and positioned between the air outlet board and net body, the gas receiving concave surface of the propellant board concentrating gas pressure to propel the bullets of the net body from the shot holes and thereby quickly deploy the net body into an umbrella shape as it is projected from the net containing tube responsive to release of high pressure gas from the high pressure gas storage device.

2. An improved anti-riot device according to claim 1, further comprising an electrical launcher for initiating release of the high pressure gas from the high pressure gas storage device.
