Abstract

A distraction device is comprised of a hollow container that is divided into a first chamber and a second chamber. An explosive charge capable of producing a loud sound and a brilliant flash of light fills the second chamber. A standard M201 hand grenade fuse is installed in the distraction device so that the fuse is in communication with the first chamber. The fuse initiates the sequential ignition of several combustible compositions in the distraction device. A first combustible composition generates a combustion gas of sufficient pressure in the first chamber to separate the expended fuse from the distraction device before the device explodes. The first composition also ignites a combustible time-delay composition, which in turn ignites a spark-producing composition that detonates an explosive output charge. Separation of the fuse from the distraction device before the explosive charge is detonated prevents the fuse from becoming a lethal projectile. The distraction device is useful in law enforcement and military encounters for distracting and temporarily disorienting a suspect or enemy.

Dependent claims

A distraction device comprising:

a container that is substantially hollow inside;
separator means within the container for dividing the inside of the container into a first chamber and a second chamber, wherein the separator means has a first surface in the first chamber and a second surface in the second chamber;
aperture means in the container for communication between the first chamber and environment surrounding the container;
rupturable membrane means for closing the aperture in the container;
opening means in the separator means for communication between the first chamber and the second chamber;
a combustible, rapid-burning, gas-producing, first composition in the first chamber over the first surface of the separator means;
a combustible, spark-producing, third composition in the second chamber over the second surface of the separator means;
a combustible, time delay, second composition in the opening means in the separator, wherein the combustible second composition is in contact with the first composition and the third composition and is capable of being ignited by the first composition and of subsequently igniting the third composition;
an explosive output charge in sufficient amount in the second chamber to produce an audible blast and brilliant flash of light to distract or disorient a subject proximate to the distraction device, wherein the output charge is ignitable by the spark-producing, third composition;
and
wherein the container is comprised of lightweight material that forms non-lethal fragments if the container breaks when the distraction device initiates.

A distraction device comprising:

a container that is substantially hollow inside, wherein the container has a front opening and an opposing rear opening;
a rear wall enclosing the rear opening of the container;
front wall means for enclosing the front opening of the container;
aperture means in the front wall means for communication between the inside of the container and environment surrounding the container;
rupturable membrane means for closing the aperture in the front wall means;
separator means within the container for dividing the inside of the container into a first chamber proximate the front wall means and a second chamber proximate the rear wall, wherein the separator means has a first surface facing the front wall and a second surface facing the rear wall;
opening means in the separator means for communication between the first chamber and the second chamber;
a combustible, rapid-burning, gas-producing, first composition in the first chamber over the first surface of the separator means;
a combustible, spark-producing, third composition in the second chamber over the second surface of the separator means;
a combustible, time delay, second composition in the opening means in the separator, wherein the combustible second composition is in contact with the first composition and the third composition and is capable of being ignited by the first composition and of subsequently igniting the third composition;
an explosive output charge in sufficient amount in the second chamber to produce an audible blast and brilliant flash of light to distract or disorient a subject proximate to the distraction device, wherein the output charge is ignitable by the spark-producing, third composition;
and
wherein the container is comprised of lightweight cardboard material that readily forms non-lethal fragments if the container breaks when the distraction device initiates.

A distraction device comprising:

a container that is substantially hollow inside, wherein the container has a front opening and an opposing rear opening;
a rear wall enclosing the rear opening of the container;
front wall means for enclosing the front opening of the container;
separator means within the container for dividing the inside of the container into a first chamber proximate the front wall means and a second chamber proximate the rear wall, wherein the separator means has a first surface facing the front wall and a second surface facing the rear wall;
opening means in the separator means for communication between the first chamber and the second chamber;
aperture means in the front wall means for communication between said first chamber of the container and environment surrounding the container;
a combustible, rapid-burning, gas-producing, first composition in the first chamber over the first surface of the separator means;
a M201 hand grenade fuse in the aperture means in the front wall means for igniting said first composition;
a combustible, spark-producing, third composition in the second chamber over the second surface of the separator means;
a combustible, time delay, second composition in the opening means in the separator, wherein the combustible second composition is in contact with the first composition and the third composition and is capable of being ignited by the first composition and of subsequently igniting the third composition;
an explosive output charge in sufficient amount in the second chamber to produce an audible blast and brilliant flash of light to distract or disorient a subject proximate to the distraction device, wherein the output charge is ignitable by the spark-producing, third composition;
and
wherein the first composition is provided in an effective amount to generate a combustion gas of sufficient pressure in the first chamber to cause separation of the M201 hand grenade fuse from the container before the output charge is ignited, and further wherein the container is comprised of lightweight material that readily forms non-lethal fragments if the container breaks when the distraction device initiates.
